The specific embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further.
Extremely shown in Figure 4 like Fig. 2; The interlock of compound saw of the present invention; Comprise interlock 1 and latch 2, interlock 1 is " L " shape, and an end of interlock 1 is connected with the bench saw workbench 6 of compound saw; The other end of interlock 1 is provided with arc groove 3, and said latch 2 passes this arc groove 3 and inserts in the diagonal cutting saw body 13 of compound saw.
Interlock 1 comprises orthogonal interlocking clamp 11 and interlocking connecting rod 12, and in the actual fabrication process, interlocking clamp 11 is in the same place for assembling through screw with interlocking connecting rod 12.Arc groove 3 comprises top circular arc and bottom circular arc, and the diameter of top circular arc is greater than the diameter of bottom circular arc.Latch 2 comprises latch cap and bolt axle, and bolt axle comprises latch leading portion 21, latch stage casing 22 and latch latter end 23 vertically, and the diameter of latch leading portion 21, latch stage casing 22 and latch latter end 23 reduces successively.
The interlock of compound saw of the present invention in use, at first the end with interlock 1 is installed on the bench saw workbench 6 of compound saw, can install through screw, also can be directly through being welded to connect; Then, the base of " L " shape interlock 1 is installed in through screw 9 on the diagonal cutting saw body 13 of compound saw, interlock 1 can serve as the axle rotation with this screw 9; At last, latch 2 is inserted in the circular hole 10 of diagonal cutting saw body 13 through arc groove 3.
When diagonal cutting saw is worked; Unclamp two lockings that are installed in body one side and handle knob 7, bench saw workbench 6 will rise to peak under the effect of two stage clips 4 so, and bench saw workbench 6 drives interlock 1 and rotates around screw 9 when rising; Make the top circular arc of the arc groove 3 on the interlock 1 and the circular hole 10 of diagonal cutting saw body 13 be in concentric position; Stir latch 2 this moment, and the latch stage casing 22 of latch 2 is stuck in the top circular arc of arc groove 3 of interlock 1, at this moment; The bolt axle of latch 2 no longer inserts in the swing arm circular hole 14 of swing arm 15, and diagonal cutting saw body 13 hex bolts in addition is an action of lifting or pressing down; This moment, locking handled knob 7, and bench saw workbench 6 is fixed, and the limiting plate 8 that goes up and down simultaneously also plays position-limiting action to bench saw workbench 6, and saw blade can not expose the upper table surface of bench saw workbench 6, promptly can the safety operation diagonal cutting saw.Because bolt axle passes circular hole 10 and the riveted joint of latch cap from diagonal cutting saw body 13 inside, and the diameter of latch leading portion 21 is greater than the diameter of the circular hole 10 of diagonal cutting saw body 13, so latch 2 can not be pulled out body 13.
When bench saw is worked, on the diagonal cutting saw workbench, be furnished with a saw blade low protection cover, body 13 is pressed down, as shown in Figure 3; Stir latch 2, the latch latter end 23 of latch 2 is stuck in the bottom circular arc of interlock 1 arc groove 3, the latch leading portion of latch 2 21 inserts in the swing arms in 15 the swing arm circular hole 14, at this moment; Body 13 can not lift again, and the saw blade that exposes below the bench saw workbench 6 partly is blocked, and unclamps two lockings and handles knob 7, bench saw workbench 6 is depressed into minimum point after locking handle knob 7; At this moment, saw blade exposes the upper table surface of bench saw workbench 6, and locking is handled knob after 7; Bench saw workbench 6 is locked, and interlock 1 presses down at bench saw workbench 6 under the drive of process, serves as the axle rotation with screw 9; Interlocking connecting rod 11 pulling interlocking clamps 12 make interlocking clamp 12 glide along screw 9, and latch 2 is positioned at the bottom circular arc of interlock 1 arc groove 3.
The interlock of compound saw of the present invention has good interlocked usefulness, and at work, pressing down of body 13 must just can be operated when bench saw workbench 6 rises to peak; Want and freely body 13 to be pressed down or to lift; Just must extract latch 2, promptly let the latch stage casing 22 of latch 2 get in the top circular arc of interlock 1 arc groove 3, if when bench saw workbench 6 does not also rise to peak; The top circular arc of interlock 1 arc groove 3 will depart from the circular hole 10 of body 13 so; The diameter of the bottom circular arc of interlock 1 arc groove 3 forces body 13 not press down less than latch stage casing 22 diameters of latch 2, security that can safeguard work.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
