Machining positioning clamp for box body of gearbox

Abstract

The invention discloses a machining positioning clamp for a box body of a gearbox. The machining positioning clamp comprises a base and a gearbox body, wherein an upper box body positioning mechanism used for horizontally fixing an upper box body, a lower box body positioning mechanism used for horizontally fixing a lower box body and a gearbox body positioning mechanism used for vertically fixing the gearbox body are sequentially arranged on the base from left to right. According to the machining positioning clamp, the upper box body of the gearbox, the lower box body and the gearbox body can be clamped at the same time; error caused by manual clamping during a machining process is reduced; and the fit precision between fit planar surfaces machined on the upper and lower box bodies is improved. The defect that the clamp needs to be changed when multiple parts are machined at the same time is overcome; the machining efficiency and machining quality are improved; and clamping force is uniform and stable due to the use of hydraulic cylinders, so that the machining precision is favorably ensured.

Description

technical field [0001] The invention relates to a processing and positioning fixture for a gearbox, in particular to a processing and positioning fixture for a gearbox case. Background technique [0002] At present, with the continuous improvement of people's living standards, automobiles have become a frequently used means of transportation. The automobile manufacturing industry is also developing rapidly. As people's requirements for the performance of automobiles are getting higher and higher, the requirements for machining accuracy of auto parts are also getting higher and higher. In the processing of the gearbox housing, since the mating end faces of the upper and lower casings of the gearbox are very precise, high machining accuracy is required. In the process of processing, since the workpiece cannot be clamped at one time, multiple parts need to be replaced back and forth, which makes the processed workpiece have large errors and is difficult to use together, which ...

AI Technical Summary

Problems solved by technology

In the process of processing, since the workpiece cannot be clamped at one time, multiple parts need to be replaced back and forth, which makes the processed workpiece have large errors and is difficult to use together, which brings great inconvenience to the processing and production of the enterprise.

At the same time, when processing the end face where the large diameter of the gearbox body is located, it is necessary to re-clamp and change the tool, which greatly increases the labor intensity and reduces the processing efficiency.
