Cross shaft drilling device for vehicle rear axle

Abstract

The invention discloses a cross shaft drilling device for a vehicle rear axle. The device comprises a drilling platform; a cross shaft clamping base and a cross shaft drilling machine are arranged on the machining platform; the cross shaft clamping base is provided with a cross shaft clamping head capable of rotating; the cross shaft drilling machine includes a left drilling machine and a right drilling machine; a cross shaft drilling machine guide rail is arranged on the tabletop of the machining platform; the left drilling machine and the right drilling machine are both movably arranged on the cross shaft drilling machine guide rail; the cross shaft clamping head includes a chuck capable of rotating; a cross shaft positioning disc is arranged in the center of the chuck; and a locking screw rod for locking a cross shaft is arranged on the cross shaft positioning disc. The cross shaft drilling device for the vehicle rear axle synchronously drills holes in two opposite directions, rotates the cross shaft by 90 degrees for drilling again, finishes total machining of the cross shaft only by two times of drilling, and is fast in speed and low in accumulation error.

Description

technical field [0001] The invention relates to a cross shaft processing device, in particular to a drilling device for a rear axle cross shaft of an automobile. Background technique [0002] The cross shaft used for the rear axle of an automobile needs to be punched at the shaft ends in four directions. In the prior art, it is usually clamped by a jig as disclosed in 2014206583292, and then punched one by one with a punching tool. The speed is slow, and the centering error of the holes at both ends is large. In view of this, there is an urgent need for a processing device that improves the drilling efficiency and reduces the cumulative error of the end holes. Contents of the invention [0003] In view of this, the object of the present invention is to provide a drilling device for the cross shaft of the rear axle of an automobile, which overcomes the above-mentioned defects of the prior art, has high drilling efficiency, and greatly reduces the cumulative error of drillin...
