Detailed description of the invention
Below in conjunction with accompanying drawing, the better embodiment of reciprocating power tool is described.
Please refer to Fig. 1 and Fig. 2, disclose the reciprocating power tool 100 of an embodiment, comprise casing 110, the gear-box 120 be arranged in casing 110, the reciprocating lever 130 be arranged in gear-box 120, with the matched case lid 140 of gear-box 120 and the motor 150 that is arranged in casing 110.The transmission mechanism 160 connecting reciprocating lever 130 and motor 150 is also provided with in gear-box 120.Motor 150 drives reciprocating lever 130 axially reciprocating along it by the transmission mechanism 160 in gear-box 120, and reciprocating lever 130 can drive working head (non-label) reciprocating.
The handle 114 that casing 110 comprises main body 112 and is connected with main body 112.Gear-box 120 and motor 150 are contained in main body 112.The setting of handle 114 makes reciprocating power tool 100 be easy to carry and operate, can internal battery in handle 114, is used for CD-ROM drive motor 150 to work, and electric power connection line also can be made to draw from handle 114 to be connected with external power source.
Please refer to Fig. 2, reciprocating lever 130 to be arranged in gear-box 120 and can to make axially reciprocating.Also be fixed with fairlead 170 in gear-box 120, reciprocating lever 130 can be arranged in fairlead 170 axially slidably.So, motor 150 drives reciprocating lever 130 axially reciprocating along it in fairlead 170 by the transmission mechanism 160 in gear-box 120.The both sides of reciprocating lever 130 are fixed with the first locating part 182 and the second locating part 184 respectively, are used for respectively being slidably matched with the first locating slot 122 on gear-box 120 and case lid 140 and the second locating slot 142.When reciprocating lever 130 is reciprocating, the first locating part 182 of both sides and the second locating part 184 can position reciprocating lever 130 from the both sides of reciprocating lever 130 respectively, and prevent from rotating during reciprocating lever 130 axially-movable, the stability of location is higher.First locating part 182 and the second locating part 184 are arranged in axially staggering of reciprocating lever 130 with fairlead 170, can simplify the structure of fairlead 170, also reduce its manufacturing cost.
In the present embodiment, the first locating part 182 and the second locating part 184 are integral type structure, and they are two ends that reciprocating lever 130 given prominence to by alignment pin 180.Please refer to Fig. 2, alignment pin 180 perpendicular to the axis X of reciprocating lever 130, and runs through reciprocating lever 130.Particularly, reciprocating lever 130 is provided with through hole (not shown), alignment pin 180 and through hole interference connect, and the two ends of alignment pin 180 protrude from the both sides of reciprocating lever 130 respectively, to form the first locating part 182 and the second locating part 184 respectively.As shown in Figure 2, gear-box 120 inwall is provided with the first locating slot 122 coordinated with the first locating part 182; Case lid 140 is provided with the second locating slot 142 coordinated with the second locating part 184, wherein the first locating part 182 and the second locating part 184 to extend into respectively in the first locating slot 122 and the second locating slot 142 and can slide along the axial direction of reciprocating lever 130.So, the both sides of reciprocating lever 130 are provided with locating part and are used for preventing reciprocating lever 130 from rotating, and when reciprocating lever 130 moves back and forth, the stability of location is higher.In addition, need point out, alignment pin 180 also can be not orthogonal to the axis X of reciprocating lever 130, as long as all outstanding reciprocating lever 130 in its two ends, and can be slidably matched with the first locating slot 122 and the second locating slot 142 respectively.
In the present embodiment, the first locating part 182 of reciprocating lever 130 both sides and the second locating part 184 are integral type structure.Be appreciated that all forming locating part in the both sides of reciprocating lever 130 also can be obtain by other means.As being also be inserted in the through hole be opened on reciprocating lever 130 from both sides respectively with two alignment pins, now effect is identical with arranging an alignment pin running through reciprocating lever 130.Also can be, in the both sides of reciprocating lever 130 respectively one-body molded go out a projection.Can also be that one in the first locating part 182 and the second locating part 184 is alignment pin, and another is integrated projection on reciprocating lever 130.In addition, when the first locating part 182 of reciprocating lever 130 both sides and the second locating part 184 are not for integral type structure, they can be corresponding in reciprocating lever 130 position axially, also can stagger, be slidably matched as long as can reach with the first locating slot 122 and the second locating slot 142.
The first locating slot 122 on gear-box 120 has two kinds of set-up modes at least.A kind of mode is: gear-box 120 inwall is fixed with keeper 124, and aforementioned first locating slot 122 is opened on keeper 124.Because the first locating slot 122 is arranged on keeper 124, when the first locating slot 122 weares and teares increase, can by changing the stability that keeper 124 recover to locate quickly and easily.Another kind of mode is: the first locating slot 122 is directly opened on gear-box 120 inwall, now, also can be understood as the first locating slot 122 and is opened in one with on the integrated keeper of gear-box 120.
Please refer to Fig. 3 and Fig. 4, a side of case lid 140 is provided with a pair gusset 144, and aforementioned second locating slot 142 is formed between a pair gusset 144.A pair gusset 144 is another side punching press from case lid 140 and bending is formed, and this kind mode technique is simple and cost is lower.Certainly, gusset 144 also can be that sheet material is fixed on the side of case lid 140 by modes such as welding and is formed.Need point out, the second locating slot 142 can also be fall into from a side fovea superior of case lid 140 to be formed.Case lid 140 is by securing member 190(screw, bolt etc.) removably connect with gear-box 120, facilitate reciprocating lever 130 and on the Installation and adjustment of locating part.Second locating slot 142 is arranged on case lid 140, and directly utilize spacing second locating part 142 of case lid 140, the element of reciprocating power tool 100 is few, easy to assembly.
To sum up, in above-mentioned reciprocating power tool 100, the both sides of reciprocating lever 130 are provided with locating part, and be slidably matched to prevent reciprocating lever 130 from rotating with the first locating slot 122 and the second locating slot 142 respectively, the stability of location is higher.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
