In addition, four sidepiece 20b are arranged in the support member 20a place of machine frame 20, and these sidepieces have sealed machine frame 20 in the embodiment shown in the side.But, in an alternative enforcement variant, naturally also can abandon these sidepieces 20b.
Support member 20a limits a receiving room in the inside of machine frame 20, is installed in the assembly of the lathe at machine frame place, and for example driver can be placed in the described receiving room by protectorate.Be a bench circular saw at this lathe of embodiment shown in Figure 1, only shown that wherein a saw arranges 60, comprise that the protection of saw blade 62 and a subordinate arranges 64, wherein, saw blade 62 just partly stretches out from a base plate 24 of machine frame 20.
During the lathe operation, base plate 24 is used for supporting workpiece to be processed.Corresponding therewith, base plate 24 has a clear and definite slit shape cavern part 26 in the zone of the saw blade 62 of bench circular saw, and saw blade 62 extends through this cavern part at least partially when lathe moves.In addition, be provided with movably block 28a and 28b at base plate 24, they can form workpiece to be processed contact-making surface (
).
At last, a rolling arrangement with two rollers 22 has been installed at machine frame 20 places, has been used for the lathe that rolling type transportation is arranged in machine underframe 10 places.
According to the present invention, for other details that is installed in machine frame 20 places, for example, cable support and the operating unit that is used for operation (switch on and off and control) bench circular saw just do not remake detailed explanation here.
In the position of machine underframe shown in Figure 1, supporting leg 30 be open and support machine frame 20 and lathe (representing with saw arrangement 60) from (a showing) bottom surface.Supporting leg 30 has feet 30a and 30b at this, and for example, they can be made by the material different from supporting leg 30 itself, especially rubber or analog, thus better skid resistance and stability are provided on the bottom surface.The difference of feet 30a and feet 30b is to have a flange, and described flange serves as the block of the supporting leg (with reference to figure 2b) that can push.Simultaneously, feet 30a is because its shape can be used as handle (with reference to figure 2c).
As following more detailed description of being undertaken by the diverse location of machine underframe, supporting leg 30 is connected through the hinge and 32 and 34 is supported on rotationally machine frame 20 places.In the first embodiment of the present invention, chain connection 32 and 34 difference be, being connected through the hinge 34 can also be with respect to machine frame 20 translation supporting leg 30 except rotating supporting leg 30 with respect to machine frame 20.
Fig. 2 a to Fig. 2 f shows is diverse location according to machine underframe of the present invention, and wherein, Fig. 2 a shows is the deposit position of machine underframe 10 and the lathe that is installed on it.Machine underframe 10 can be transformed into transporting position by a flip-flop movement (with reference to the arrow that indicates with " B " among the figure 2b).For the rolling transportation that makes machine underframe and the lathe that is installed on it is easier, at least overwhelming majority of two supporting legs 30 that is accommodated in the receiving room inside of machine frame 20 in deposit position is pulled out (with reference to the arrows of using " C " sign the figure 2c) from receiving room.In this position, namely so-called go-cart position can easily be transported to another place to the machine underframe from a place as luggage truck, and wherein, the supporting leg 30 that stretches out can be used for the machine underframe guiding that will roll and turn to.
If the machine underframe enters the operating position among Fig. 2 f now, two other supporting leg also will rotate out from receiving room (with reference to the arrow that indicates with " D " the figure 2d) so, and is used for guiding the supporting leg 30 of machine underframe 20 to rotate (with reference to the arrow that indicates with " E " among the figure 2e) to the operating position with respect to this machine underframe.At last, must again turn over the machine underframe, in order to enter the operating position, whole four supporting legs all are used to be supported on the bottom surface in the operating position again.
Each the spendable position that has again shown in detail the machine underframe at Fig. 3 a to Fig. 3 c.At Fig. 3 d, the machine underframe is in its operating position shown in Fig. 3 c, still, is not to be front view but side view as Fig. 3 a-c.
Fig. 3 a to Fig. 3 c conforms to the machine underframe shown in Fig. 2 a to Fig. 2 f with Fig. 1 substantially with the second embodiment shown in Fig. 3 d, wherein, this embodiment does not have side cover plate (Seitenwangen) 20b and the lathe above the machine underframe that can be installed in is omitted.In addition, the difference of the embodiment shown in Fig. 3 a to Fig. 3 d has been to give prominence to the movably feet of supporting leg.Feet 130a shown in Fig. 3 a to Fig. 3 d forms by this way, and namely they not only can also be as block as handle in the go-cart position as in the first embodiment.Yet since its embodiment they the machine underframe is difficult in its operating position or stops and occur undesirablely to topple over and so make machine underframe 110 have higher stability in its operating position.
From figure, especially in Fig. 3 c and Fig. 3 d, can identify, difference between chain connection or hinge 132 and 134 is: 132 on the hinge that Fig. 3 c left side shows is used for the supporting leg 130 of subordinate is supported on machine frame 120 places, wherein, especially can from Fig. 3 d, identify, the support member 120a of the subordinate of machine frame 120 is not parallel with base plate 124 in the zone that hinge 132 is installed, but tilts towards base plate a little.Cause thus, hinge 132 and therefore with hinged supporting leg 130 at the turning cylinder that can rotate about it with respect to machine frame 120, tilt equally relative to each other.Can realize that whereby supporting leg 130 has larger supporting surface in the bottom surface in the pull-out location, and supporting leg 130 can leave better in the receiving room in folding into the position in, and can not stop each other.
Hinge 132 can comprise two hinge fractions, and they form first collecting part of frame support 120a jointly, and they are installed in described collecting part place, and second collecting part of supporting leg to be fixed.Supporting leg can be installed in hinge 132 places by diverse ways, and for example, collecting part can be tapered, and causes the supporting leg of an insertion to remain in the collecting part by friction.Also can consider the fixing means variant that substitutes, for example cooperate by form fit or material.
In addition, can in the zone of the first collecting part, setting can make corresponding hinge 132 with the mode of the least possible friction device with respect to frame support 120a rotation, for example, sliding axle carrier ring or analog.At last, a release mechanism or a safety arrangement 150 can be set in order to corresponding hinge is protected with respect to frame support 120a at least one position in the zone of the second collecting part.
In addition, in order to guarantee that the machine underframe can reliably and safely support a workpiece to be processed in the operating position, also be provided with a safety and arrange 150, described safety is arranged in and can stops supporting leg 130 also to forbid that with respect to undesirable rotation of machine frame 120 and in chain connection 134 supporting leg 130 moves with respect to machine frame 120 except stoping undesirable rotation in the chain connection 132.
This type of safety arranges 150 can pass through, and for example, displaceable braking bolt or analog form, and in order to prevent undesirable rotation, described braking bolt can mesh with a corresponding Ministry of State Security that is positioned at the frame support 120a place of subordinate.This type of corresponding Ministry of State Security can comprise a cavern part, depression or to block (Gegenanschlag).Safety element can directly be arranged in frame support 120a place or be arranged in one extraly with above the part that it is fixedly connected with, for example, and a keep plate.In addition, displaceable braking bolt can form a block and stop whereby supporting leg with respect to undesirable translation of chain connection 134.
In the enforcement variant that can imagine, can in the zone of the second collecting part of hinge 132 or 134, arrange one with the brake lever of the braking bolt of subordinate, described lever energy joins in the cavern part at frame support 120a place of subordinate, so that hinge 132 or 134 is fixed on its position.Same braking bolt or another braking bolt can serve as the block of the supporting leg 130 in the second collecting part of hinge 134 and this supporting leg is remained on its extended position.Can by following manner simply the motion lever to discharge safeguard construction 150, thereby make braking bolt break away from corresponding engagement, like this this bolt just can make hinge 132 or 134 move with respect to frame support 120a motion and/or supporting leg 130 chain connection 134 with respect to subordinate.Especially preferred, safety arranges 150 can have extraly a flexible member, and described flexible member is the similar pre-tensioner position a safety of safety device.
What Fig. 4 a to Fig. 4 d showed is another embodiment of a machine underframe of the present invention, is that enforcement or the supporting leg 230 of machine frame 220 is all different from the first two embodiment being articulated and connected of machine frame 220 places in described machine underframe.The view of Fig. 4 a to Fig. 4 d is corresponding to Fig. 3 a to Fig. 3 d.
The machine frame 220 of the 3rd embodiment comprises that equally 224, four frame support 220a of a base plate stretch from base plate downwards as table leg.In order to carry out firmly also being provided with extra support member 254, these support members are such as hereinafter also being used as to institute's descriptions the guide rail of the supporting leg that can move into.
Implement in the variant at this, folding supporting leg 230 is not only hingedly, can be connected with machine frame 220 rotationally with respect to machine frame, but also can be installed in movably the machine frame place.Here, the support member of each leg shape of machine frame 220 or leg support member 220a have a cavern part 240 (shown in the dotted line among Fig. 4 b), and supporting leg 230 stretching, extensions are passed described cavern part and are pushed in the receiving room by described cavern part.
Translation by two blocks 250 above the supporting leg 230 and 252 restriction supporting legs 230.Here, the first block 250 that is arranged in the receiving room is to form by an independent element, and described element is connected with the supporting leg 230 of subordinate by a chain connection 234.Block limits each supporting leg 230 on the one hand from the motion of pulling out of the receiving room of machine frame 220.In addition, block 250 can also serve as the slip pin that is directed in guide rail 254.
Here, chain connection 234 consists essentially of a slotted hole 234b, and a carrying bolt 234a is accommodated in the described slotted hole rotationally and movably.Here, carrying bolt 234a is fixedly connected with supporting leg 230, and slotted hole 234b belongs to stop element 250.In addition, chain connection 234 comprises two hinge fractions, leg support and leg articulated elements, and they are fixedly connected with supporting leg 230 or block 250 respectively an end.Form slotted hole 234b in another end separately of hinge fraction or take within it carrying bolt 234a.
If supporting leg 230 is pulled outward by cavern part 240 now as far as possible, until block 250 is run into the inboard of leg support member 220a, the slotted hole 234b of chain connection 234 usefulness carrying bolt 234a and subordinate then stretches out at the opposite side of frame supported 220a so, thereby causes the supporting leg 230 can be with respect to block 250 and also can rotate (with reference to figure 4c) with respect to machine frame 220.By the deadweight of machine frame 220, carrying bolt 234a to lower support, causes cavern part 240 to move with respect to the top edge of the leg articulated elements of chain connection 234 in slotted hole 234b inside.Therefore, in this mechanism, can stop the undesirable of supporting leg 230 to open or push by automatically locking.
The contact-making surface of machine frame 220 outsides and the orientation of slotted hole 234b are to select by this way equally, and when namely only having the upper end of slotted hole 234b in carrying bolt 234a reclines Fig. 5 c, the supporting leg 230 of subordinate could rotate.Carrying bolt 234a can only realize by following manner with respect to this position of slotted hole 234b, namely, the machine underframe is raised or moves to another position (can compare with position shown in Fig. 2 b), the user can make supporting leg 230 move towards machine frame 220 in the mode of expectation in described position, until he can rotate supporting leg with respect to machine frame 220.Only have when supporting leg 230 rotates with respect to machine frame 220, supporting leg just can be conducted through cavern part 240 and be pushed in the receiving room of machine frame 220.
Wherein, in receiving room, push supporting leg 230 constantly, until the second block 252 of machine frame 220 outsides that recline.Can find out that from Fig. 4 d the second block 252 plays stabilization extraly, its mode is for interconnecting two supporting legs 230 respectively.
In addition, since supporting leg 230 be by support 254 and block 250 by one-sided guiding, when it is in folding and pushes in the position also for the protection of the machine tool assembly that is placed in the receiving room.
