Description
Technical field
the utility model belongs to a kind of mechanical Special tool for assembling, assembling when being mainly used in gonnecting rod body two support bolt.Also can be used for the assembling of similar workpiece.
Background technology
the assembling of gonnecting rod body bolt (seeing Fig. 1,2,3), Main Function is that gonnecting rod body I and connecting rod cap II are connected, on connecting-rod bolts A, there is one section with the optical axis of groove, with the unthreaded hole interference fit in gonnecting rod body I, and by bolt A, connecting rod cap II is accurately fixing.When engine operation, connecting rod ASSY not only can bear radial load can also bear transverse load, guarantees that the connecting rod ASSY of engine normally moves.Wherein, L is the width of the major part nose end of gonnecting rod body I, and H is the height of gonnecting rod body I unthreaded hole, the concave station breach that B is gonnecting rod body, and C is the thickness of gonnecting rod body I.For a long time, such connecting-rod bolts assembling has mainly been combined by craft and hydraulic press.First a support bolt A is put into the unthreaded hole of gonnecting rod body, the head of rotating bolt, bolt head is alignd with the concave station breach B of gonnecting rod body, then knock bolt head with "painted-face" character in opera, the reeded optical axis of bolt band is knocked in the unthreaded hole of gonnecting rod body (1/2nd places of the high H of gonnecting rod body I unthreaded hole).Use the same method and complete again the assembling of another support bolt.Two support bolts are manual to be completed after assembling, puts on the workbench of hydraulic press again together with gonnecting rod body, two support bolts is depressed into the plane of the concave station breach B of gonnecting rod body.Hand assembled bolt requires high to operator's technical ability; secondly; with "painted-face" character in opera, knock bolt in the process of bolt head (ellipse) and often there will be rotation phenomenon; cause bolt head can not align with the concave station breach of gonnecting rod body; at this moment operative employee will pound out bolt with "painted-face" character in opera; readjust after bolt head aligns with the concave station breach of gonnecting rod body and knock in again bolt, again with hydraulic press, be pressed into.The assembling repeatedly of bolt has destroyed the magnitude of interference of gonnecting rod body unthreaded hole and bolt band groove optical axis, and efficiency of assembling is lower like this, difficult quality guarantee, and bolts assemblies will cause gonnecting rod body to be scrapped together with bolt after surpassing three times simultaneously.Badly influence completing of the connecting rod production schedule.Head it off, imperative at present.
Summary of the invention
the main technical problems to be solved in the utility model and object are: the defect existing according to gonnecting rod body bolts assemblies operation, and design a kind of special fixture and replace existing assembling mode, fundamentally overcome efficiency of assembling lower, the phenomenon that difficult quality ensures.Realize and effectively improve efficiency of assembling, guarantee the quality of workpiece assembling process, and adapt to the demand of producing in enormous quantities.
main technical schemes of the present utility model: gonnecting rod body bolts assemblies fixture comprises lower bolster, backing plate, locating piece, guide plate, rear position plate, guide pillar, return spring, depression bar, depression bar elbow-board, cover plate, guide pin bushing, cope match-plate pattern, die shank, pin, hexagon socket head cap screw, concrete structure:
lower mold mechanism, on lower bolster, with the fixing backing plate of pin and hexagon socket head cap screw, two locating pieces and two guide plates are fixed on to the right and left of backing plate with pin and hexagon socket head cap screw, after assembling, guarantee that the distance between two locating pieces is consistent with the width dimensions of gonnecting rod body major part nose end, rear position plate is fixed on backing plate with pin and hexagon socket head cap screw, after having assembled, the pilot hole centre distance that guarantees rear position plate and guide plate is 1/2nd of gonnecting rod body gauge, again guide pillar lower end is assemblied on lower bolster, return spring is sleeved on guide pillar;
upper die mechanism; depression bar is assemblied on depression bar elbow-board; depression bar elbow-board is connected with hexagon socket head cap screw with pin with cover plate and is fixed on cope match-plate pattern; assembled the face of two depression bars of rear assurance in same plane; die shank is fixed on cope match-plate pattern with hexagon socket head cap screw; again guide pin bushing upper end is assemblied on cope match-plate pattern to the endoporus on guide pin bushing endoporus and cope match-plate pattern both sides and guide pillar matched in clearance.
the utility model proves by practical application: gonnecting rod body bolts assemblies clamp structure is simple, easy to operate, and the assembly quality of workpiece is stable.Technical ability to operating personnel is less demanding, has cancelled hand assembled work step, and labour intensity significantly reduces.The generation of having stopped waste product, efficiency of assembling at least improved more than three times than originally, had guaranteed completing smoothly of the production schedule, can meet the needs of large-scale production.
