Abstract
The utility model discloses a clamp for assembling a connecting rod bush, which is mainly used for assembling a bush for an engine connecting rod with a wedged structure at the small end. The main technical scheme is as follows: a bracket is fixed at the right side of a base; an adjusting screw is arranged on the bracket; a slot is arranged above the right part of the base; the slot is internally provided with a wedged positioning block; a core shaft is coaxially arranged in a hole at the right part of the base; a connecting rod large-hole positioning core shaft is arranged at the left part of the base; simultaneously, two positioning blocks are arranged at the front part and the rear part of the positioning core shaft respectively. Proved by the practical application, the defects of sliding and deformation generated in the assembling process of the original bush, and low qualified rate of products can be overcome radically, therefore, the assembling quality and efficiency of the connecting rod bush can be improved effectively, and the requirements on batch production of the connecting rod can be met.
Description
One, technical field
The utility model belongs to a kind of press assembling jig, is mainly used in the engine link assembling lining of microcephaly for wedge structure.
Two, background technology
Usually assemble the method (seeing Fig. 1,2) of lining, be directly connecting rod 1 to be placed on the supporter, connecting rod do not positioned or fix, lining 2 is enclosed within on the mandrel, mandrel is aimed at the microcephaly hole of connecting rod 1, and forcing press moves downward and promotes mandrel lining is pressed in the small end of connecting rod hole.The connecting rod that assembles lining is by follow-up machined, and the part that the removal lining is higher than the small end of connecting rod inclined-plane gets final product.Because the small end of connecting rod structure is wedge shape, when the assembling lining, bush end face is at 2 with the inclined-plane of small end of connecting rod and contacts that lining can produce and slide, distortion in assembling process, even the appearance phenomenon that can't be pressed into.Operating efficiency is very low, and product is difficult to meet specification requirement, has a strong impact on manufacturing schedule, the incompatible demand of producing in batches far away.
Three, utility model content
The main technical problems to be solved in the utility model and purpose are: the problem that occurs when the assembling lining for the connecting rod of wedge structure according to the microcephaly, design a kind of assembling jig that has positioning and fixing and accurately lead, fundamentally overcome and produce defectives such as slip, distortion in the lining assembling process, improve the quality and the efficient of connecting rob bushing assembling effectively, satisfy the demand that this kind connecting rod is produced in batches.
Main technical schemes of the present utility model: the structure of anchor clamps is, fix a support on the base right side, adjustment screw is housed on support, a groove is arranged on the base right part, wedge locating block is installed in the groove, and mandrel of coaxial installation in the hole of base right part is installed a connecting rod macropore positioning core axle at the base left part, on the both sides, front and back of positioning core axle, a locating piece is installed respectively simultaneously.
The utility model proves by practical application: anchor clamps are reliable and stable at work, guiding is good during the lining assembling, lining is pressed into quality and meets specification requirement, the assembling qualification rate rises to more than 95% by original 60%, it is about about 30% to reduce loss due to spoiled work, has solved the problem of microcephaly for the connecting rob bushing assembling difficulty of wedge structure.Can satisfy the demand that this kind connecting rod is produced in batches.
Four, description of drawings
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is done to describe in further detail.
Fig. 1 is to have assembled connecting rod 1 front view of the microcephaly of lining 2 for wedge structure.
Fig. 2 is the lining figure before the assembling.
