Embodiment

[0035] see details figure 1 :

[0036] A processing method for a special-shaped bearing bush, comprising the following steps:

[0037] Need to use a fixture, the fixture includes a base 1, the base 1 can be made of No. 45 steel, or spring steel, the base 1 is a cylinder, and the base 1 is provided with an inclined hole 8, which is eccentrically opened on the base 1. The inclination of the inclined hole 8 is greater than 0° and less than or equal to 21.3°. In this embodiment, the inclination of the inclined hole 8 is 12°. There is a threaded hole on the left end wall of the base body 1, and a stopper 6 and a hexagonal bolt 5 are also included. , There is a through hole on the block 6, the hexagonal bolt 5 passes through the through hole and is screwed into the threaded hole, the upper side of the block 6 is used to block part of the inclined hole 8, and there is a first expansion joint 3 and three The second expansion joint 4, the first expansion joint 3 and several second ex...

Abstract

The invention relates to the technical field of special-shaped bearing bush production, and discloses a machining method of a special-shaped bearing bush. The machining method comprises the following steps that a clamp needs to be used, the clamp comprises a base body, an inclined hole is formed in the base body, a check block is in threaded connection with the end wall of one end of the base body, one side of the check block blocks part of the inclined hole, and a first expansion gap and a plurality of second expansion gaps are formed in the base body. The first expansion gap and the second expansion gaps are uniformly distributed on the base body in the circumferential direction of the inclined hole, and the first expansion gap penetrates through the base body and communicates with the inclined hole. The machining method comprises the steps of A, workpiece clamping; B, mounting of the clamp; C, primary bevel cutting; and D, secondary slope cutting. The inclination degree of the inclined hole is set, so that the inclination degree of the cutting inclined plane is obtained, a turning tool does not need do other motions during feeding, the turning tool is not prone to damage in the cutting process, and the problems that in the prior art, the inclination degree of the cutting inclined plane is inaccurate, and the turning tool needs to run in a specific route in the cutting process, so that the turning tool is prone to damage are solved.

Description

technical field [0001] The invention relates to the technical field of producing special-shaped bearing pads, in particular to a processing method for special-shaped bearing pads. Background technique [0002] With the continuous development of productivity, the difficulties encountered in the processing are constantly being overcome by people; special-shaped bearing bushes, small models, and high-power special accessories, because of their difficulty in processing and high cost, will be used in large-scale international automobiles in 2019. According to the development seminar, automakers also hope that parts companies can improve the processing of special-shaped bearings in order to better reduce the processing difficulty and cost of special-shaped bearings. [0003] The special-shaped bearing pad refers to the non-standard cylindrical bearing pad. The end surface of the special-shaped bearing pad often has a beveled part. The current process of processing the beveled surf...
