Description
Technical field
The present invention relates to small tool, be specifically related to a kind of frame saw of two-sided clamping saw blade.
Background technology
Pincers worker is very important work post in machining, and along with the fast development of equipment manufacture and the extensive use of high-end Precision Manufacturing Technology, the status of pincers worker in manufacturing industry is also more and more higher.Sawing processing is one of basic skills of pincers worker, and the quality of sawing and speed directly affect the quality of the follow-up processing of product and quality.The main tool of sawing is frame saw.There is following shortcoming in existing frame saw: the one, and it is spacing by rivet that the front end of saw bow is connected with expansion link, rivet is easily thrown off from saw bow, causes expansion link and saw bow fixing not firm, causes fractureing of saw blade, is difficult to restore to the original state once rivet and saw bow are thrown off; The 2nd, one end that expansion link puts in saw bow is pressed into convex, and this structure is easy to make expansion link and saw bow to separate; Thereby affect the normal use of frame saw; The 3rd, the two ends of fixing saw blade are by steady pin and single plane, and have straight trough on the face of cylinder of steady pin, cause the intensity of steady pin to be seriously undermined, and in the time of sawing, are very easily subject to tightening to cause and fractureing of the swing wearing and tearing of saw blade and saw blade.Steady pin and pull bar are blind hole tight fits, after steady pin is broken, cannot repair, and the pull bar that can only more renew, can increase maintenance cost and the waste that causes material like this; The 4th, the mode of steady brace is the rectangular surfaces curving by sheet steel material, and this structure increases fit clearance between pull bar and rectangular surfaces, the swinging of saw blade while easily causing sawing, thus cause saw kerf to depart from sawing position, even cause product rejection.
Summary of the invention
The object of the present invention is to provide a kind of frame saw of rational in infrastructure, two-sided clamping saw blade easy to use.It can improve service life, the reliability of sawing and the efficiency of processing of existing frame saw, reduces use cost, eliminates safe hidden trouble.
For achieving the above object, technical scheme of the present invention, it comprises saw bow, expansion link, front retainer ring and rear retainer ring, described saw bow is made F type, and its one end is provided with handle, and the other end is provided with screwed hole, centre position is provided with rear retainer ring, in described screwed hole, is furnished with stop screw; Described expansion link is made L-type, its one end is provided with hook groove, the other end is provided with front retainer ring, the long limit of described expansion link is provided with multiple semicircle stopper slots, one end containing hook groove on described expansion link extend in saw bow, is connected with saw bow by the engaging of stop screw and semicircle stopper slot; In described front retainer ring, be provided with front main tie and front subtie, described front main tie is followed closely and is connected by prelocalization with front subtie; In described rear retainer ring, be provided with rear main tie, one end of described rear main tie is connected with rear retainer ring by wing nut, and the other end matches with rear subtie by connecting pin and rear locating pin.
In technique scheme, described front retainer ring and rear retainer ring endoporus are respectively provided with four equal and opposite in directions and orthogonal plane, and described front main tie and the surface of front subtie are respectively provided with the face of isosceles right triangle, and its one end is made T-shaped; The face of cylinder of described rear main tie is provided with four equal and opposite in directions and orthogonal plane, one end that described front main tie and front subtie coordinate is provided with a gap that saw blade is thick, and one end that described rear main tie coordinates with rear subtie is also provided with a gap that saw blade is thick.
Adopt after technique scheme, can eliminate expansion link and come off from saw bow, realize the reliable location of saw blade on saw bow, avoid the accident of saw blade alignment pin to rub, thereby cause the rising of maintenance cost and the waste of material.
