Automobile rear axle reducer shell large end face drilling clamp

Abstract

Disclosed is an automobile rear axle reducer shell large end face drilling clamp. A drill plate device is arranged at the bottom of an automobile rear axle reducer shell. The automobile rear axle reducer shell is fixed to the drill plate device through a clamping device. The two ends of the drill plate device are connected with a left rotation device and a right rotation device which are arranged on a clamp support correspondingly. The automobile rear axle reducer shell rotates through a rotation air cylinder arranged on the left rotation device. A locating air cylinder is arranged under a drill jig top plate in the drill plate device. The locating air cylinder is connected with an air channel of a rotation connector of the right rotation device through an air passage. According to the automobile rear axle reducer shell large end face drilling clamp provided by the invention, the automatic locating air cylinder and the rotation air cylinder are adopted in the drilling clamp, so that automatic locating and overturning of a workpiece are achieved, and accordingly the precision and quality of hole machining of the workpiece are improved. The automobile rear axle reducer shell large end face drilling clamp is simple in structure, convenient to operate, light, handy and attractive. The problem of air pipe torsion during workpiece overturning is solved, the operation safety is improved, the labor intensity of workers is relieved, and the work efficiency is improved by 20% or above.

Description

technical field [0001] The invention relates to a drilling jig, in particular to a drilling jig for the large end face of the casing of the automobile rear axle. Background technique [0002] There are multiple holes on the large end face of the automobile rear axle reducing shell that need to be processed. There are many types of holes and high technological requirements. During the process of processing the holes, the workpiece needs to be turned over many times to discharge the iron filings generated during the construction to facilitate construction. The existing drilling jig for the large end face of the rear axle casing of the automobile is positioned by manual visual inspection of the gap, and the chips are removed by manual multiple flipping. Using this method, the labor intensity of the workers during the construction process is high, and there are inaccurate positioning of the processing holes. The problem. Contents of the invention [0003] The technical proble...
