A cross shaft connection processing system and processing technology

Abstract

The invention relates to the field of cross shaft processing, in particular to a cross shaft connection processing system and processing technology, comprising a fixed base and a moving frame, a moving chute is provided on the top of the fixed base, the moving frame is slidably installed in the moving chute, and the moving frame A support frame with an annular structure is fixedly installed on the top of the support frame, and two symmetrically arranged first cylinders and two symmetrically arranged second cylinders are fixedly installed on the inner wall of the support frame. The installation position of the first cylinder is the same as that of the second cylinder. The installation positions are alternately distributed. The existing cross shaft machining methods tend to cause inconsistent grinding accuracy of the end of the same cross shaft when processing the cross shaft, and also easily lead to inconsistent opening positions and depths of the screw holes at the end of the cross shaft. The invention solves the problem that the grinding precision of the end of the cross shaft, the position and the depth of the opening holes are not consistent when processing the cross shaft in the existing cross shaft processing method.

Description

technical field [0001] The invention relates to the field of cross shaft processing, in particular to a cross shaft connection processing system and a processing technology. Background technique [0002] Cross shaft connection generally refers to a cross shaft rigid universal joint, which generally consists of a cross shaft and two universal forks. It is used for the position where the direction of the transmission axis needs to be changed. It is the "joint" part of the universal transmission of the automobile drive system. [0003] The cross shaft is generally processed by casting. After the cross shaft is processed and formed, there will generally be a large number of metal burrs on the surface. At this time, the cross shaft cannot be used directly. Therefore, after the cross shaft is cast and formed, it generally needs to go through For grinding, it is also necessary to open a screw hole at the cross end of the cross shaft so that the universal fork can be connected to t...

Problems solved by technology

[0003] The cross shaft is generally processed by casting. After the cross shaft is processed and formed, there will generally be a large number of metal burrs on the surface. At this time, the cross shaft cannot be used directly. Therefore, after the cross shaft is cast, it generally needs to pass through At the same time, it is necessary to open a screw hole at the cross end of the cross shaft to connect the universal fork to the cross shaft. However, most of the existing cross shaft grinding methods are to fix the cross shaft with a clamp and then manually grind it. The device and the drilling device grind and drill the cross shaft. When grinding and drilling, it is necessary to process the cross end of the cross shaft through multiple operations. When using this processing method to process the cross shaft, it is easy to make the same cross shaft The grinding accuracy of the shaft end is inconsistent, and it is easy to cause the position and depth of the screw hole at the end of the cross shaft to be inconsistent. This situation is likely to affect the subsequent connection between the cross shaft and the universal yoke, which brings inconvenience to the processing of the cross shaft connection, and The existing cross shaft processing method is not efficient when processing the cross shaft, which brings inconvenience to the processing of the cross shaft connection
