Abstract
The invention discloses a reciprocating lever part for a reciprocating saw. The reciprocating lever part comprises a reciprocating lever, a cutter clamping apparatus and a locating apparatus. The cutter clamping apparatus is arranged at one end of the reciprocating lever, and the locating apparatus is arranged at the other end of the reciprocating lever. The locating apparatus comprises a locating pin, a pair of sliding blocks and a casing tube. The locating pin is fixed on the reciprocating lever, the pair of sliding blocks is detachably mounted at two ends of the locating pin, and the casing tube is fixed on a casing of the reciprocating saw. The sliding block slides along the inner wall of the casing tube when the reciprocating lever reciprocates. The reciprocating lever part is low in manufacture cost and long in service life.
Description
Technical field
The present invention relates to a kind of reciprocating saw, relate in particular to a kind of reciprocating lever parts of reciprocating saw.
Background technology
The saw blade that reciprocating saw generally includes motor, gear transmission part, reciprocating lever parts, is arranged on the fork parts between gear transmission part and the reciprocating lever parts and moved back and forth by the drive of reciprocating lever parts.Wherein, reciprocating lever only need have along its axial free degree, and in order to limit its radial and axial rotary freedom, reciprocating saw also arranges positioner at reciprocating lever usually.A kind of positioner of the prior art is included in a pair of locating part of stopper of end welding of reciprocating lever, one-body molded both sides at stopper and is installed in sleeve pipe on the reciprocating saw.This sleeve pipe is provided with chute, and above-mentioned locating part can be slidingly matched in sleeve pipe along this chute.
Yet stopper in the above-mentioned positioner adopts steel-casting, the difficult processing of its profile and need being welded on the reciprocating lever, thereby manufacturing process's more complicated and cost are higher; In addition, the mating surface between this locating part and the sleeve pipe is less, is worn easily, so shortened the service life of reciprocating lever parts.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of cheap for manufacturing cost and service life the reciprocating lever parts of long reciprocating saw.
In order to solve the problems of the technologies described above, the present invention gets by following technical proposals and solves: a kind of reciprocating lever parts of reciprocating saw, comprise reciprocating lever, be arranged on the knife-clamping device of an end of reciprocating lever and the positioner that is arranged on the other end of reciprocating lever, it is characterized in that: described positioner comprises the alignment pin that is fixedly mounted on the described reciprocating lever, be removably mounted on a pair of slide block at the two ends of described alignment pin, and be fixedly mounted on sleeve pipe on the housing of described reciprocating saw, when described reciprocating lever was reciprocating, described slide block slided along the inwall of described sleeve pipe.
In addition, the present invention also proposes following attached technical scheme:
Described reciprocating lever arranges through hole, described alignment pin and described through hole phase interference fit.
Described alignment pin is vertical mutually with described reciprocating lever.
Described slide block is dismountable to be set on the described alignment pin.
Described slide block can rotate with respect to described alignment pin.
The inwall of described sleeve pipe is provided with chute, and described slide block can slide in described chute.
The shape of described slide block is roughly rectangle, and is made by powder metallurgy.
Compared with prior art, the invention has the advantages that: reciprocating lever parts provided by the present invention, positioner wherein by be fixedly mounted on alignment pin on the described reciprocating lever, be removably mounted on described alignment pin two ends a pair of slide block and be fixedly mounted on sleeve pipe on the housing of described reciprocating saw, described slide block slides along the inwall of described sleeve pipe, contact area between slide block and the sleeve pipe is bigger like this, more wear-resisting, so long service life, those parts processing and manufacturings are simple, cost is cheaper.

Fig. 2 is the three-dimensional installation diagram of the reciprocating lever parts of reciprocating saw among Fig. 1.
Fig. 3 is the section plan of reciprocating lever parts among Fig. 2.
Fig. 4 is the cutaway view of A-A line in Fig. 3.
The specific embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof technical solution of the present invention is done further nonrestrictive detailed description.
With reference to Fig. 1, reciprocating saw corresponding to preferred embodiment of the present invention, it is mainly used in timber is cut, and the saw blade 14 that comprises motor 20, gear transmission part 31, reciprocating lever parts 34, is arranged on the fork parts 38 between gear transmission part 31 and the reciprocating lever parts 34 and moved back and forth by 34 drives of reciprocating lever parts.
With further reference to Fig. 2 to Fig. 4, above-mentioned reciprocating lever parts 34 comprise reciprocating lever 13, are arranged on the knife-clamping device 9 of an end of reciprocating lever and the positioner 11 that is arranged on the other end of reciprocating lever, and wherein knife-clamping device 9 is matched with above-mentioned saw blade 14.These reciprocating lever parts 34 are supported on the enclosure interior of machine by bearing block 17.Reciprocating lever 13 is one-body molded reciprocating lever plug 18, and an end of above-mentioned fork parts 38 inserts in this reciprocating lever plug 18, for reciprocating lever 13 provides reciprocating force.
The a pair of slide block 8 at the two ends that above-mentioned positioner 11 comprises the alignment pin 7 that is fixedly mounted on the reciprocating lever, be removably mounted on alignment pin 7 and be fixedly mounted on sleeve pipe 10 on the housing of described reciprocating saw, when described reciprocating lever 13 was reciprocating, described slide block 8 slided along the inwall of described sleeve pipe 10.Particularly, reciprocating lever 13 arranges through hole 15 in the direction perpendicular to its axial B, described alignment pin 7 and described through hole 15 phase interference fit, and alignment pin 7 is vertical mutually with reciprocating lever 13.In addition, give prominence to respectively outside through hole 15 at the two ends of alignment pin 7, above-mentioned this to slide block 8 dismountable two ends that are set in described alignment pin 7 respectively.The shape of described slide block 8 is roughly rectangle, and is made by powder metallurgy.The inwall of described sleeve pipe 10 is provided with chute 12, and described slide block 8 can slide in described chute 12.Like this, setting by the rectangular shaped slider 8 made by powder metallurgy, slide block 8 is set on the alignment pin 7, and can relatively rotate between slide block 8 and the alignment pin 7, make that slide block 8 can not suppressed extremely when reciprocating saw had longitudinal oscillation in cutting in sleeve pipe 10, and the contact area between slide block 8 and the sleeve pipe 10 is big, more wear-resisting, so service life is longer, and its processing and manufacturing cost is cheaper.
It is pointed out that above-mentioned preferred embodiment only is explanation technical conceive of the present invention and characteristics, its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit essence is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
