Rapid clamping device for machining split grooves of oblique connecting rod of automobile by linear cutting

Abstract

The invention discloses a rapid clamping device for machining split grooves of an oblique connecting rod of an automobile by linear cutting. The rapid clamping device comprises a horizontally arranged large bottom plate and a small bottom plate connected to the top surface of the large bottom plate; the top surface of the small bottom plate is connected to a small head hole positioning pin capable of abutting against the inner hole wall of a small head hole of the oblique connecting rod, and the edge of the large bottom plate is provided with a pair of large head hole positioning pins capable of abutting against the inner hole wall of a large head hole of the oblique connecting rod. Compared with the prior art, the technical solution of the invention has the advantages that by adjusting the position of positioning pin sliding blocks, the position of the large head hole of the oblique connecting rod can be fixed in advance, rapid and precise positioning can be realized, and consistency between the depths and perpendicularities of split grooves in the two sides can be ensured. By using the small head hole positioning pin and the large head hole positioning pins to limit and fix three positions of the oblique connecting rod, a rubber push block ensures positioning accuracy and stability in a machining process, such that the quality of the split grooves is higher. The small head hole positioning pin and the positioning pin sliding blocks can be moved, such that the rapid clamping device is suitable for clamping of the oblique connecting rods of various types, and thus has greater universality.

Description

technical field [0001] The invention relates to the technical field of automobile connecting rod cracking groove processing, in particular to a fast clamping device for wire cutting processing automobile inclined connecting rod cracking grooves. Background technique [0002] The connecting rod is an important part of the engine. It connects the piston and the crankshaft, and transmits the force on the piston to the crankshaft, thereby converting the reciprocating motion of the piston into the rotational motion of the crankshaft. Therefore, the precision of the connecting rod body and the connecting rod cover Processing and assembly are critical and difficult. [0003] With the continuous development of the automobile industry, the connecting rod cracking groove processing technology is a manufacturing technology that breaks through the traditional processing concept. Among them, when processing the connecting rod, it is necessary to process the cracking groove at the predet...

AI Technical Summary

Problems solved by technology

If the inner diameter of the large end hole and the inner diameter of the small end hole of the connecting rod do not meet the predetermined requirements, the clamping of the connecting rod becomes very difficult, and even the clamping process cannot be performed.

At the same time, every time a type of connecting rod is processed, the corresponding fixture needs to be replaced, which not only increases the time cost, but also increases the fixture cost accordingly
