Boring automatic centering clamp of drive axle housing

Abstract

The invention provides a boring automatic centering clamp of a drive axle housing, relating to a clamp for the mechanical processing field. The boring automatic centering clamp comprises a fixing base, and two sets of clamping positioning devices symmetrically connected to two ends of the fixing base, wherein each set of clamping positioning devices comprises a transmission case, a sliding block I, a sliding block II, a clamping block I and a clamping block II; a slide rail is mounted on the top wall of the transmission case; the sliding block I and the sliding block II are glidingly connected to the slide rail, and protruded on the upper surface of the top wall of the transmission case; the clamping block I is connected to the sliding block I, while the clamping block II is connected to the sliding block II; symmetrically mounted clamping parts having the same shape are concavely arranged in the clamping block I and the clamping block II, respectively; and the transmission case is internally provided with a transmission mechanism for sliding the sliding block I and the sliding block II to reversely move on the lead rail in order to control the clamping block I and the clamping block II to clamp or release the drive axle housing. The boring automatic centering clamp provided by the invention has the advantages of automatically aligning the axes of the sleeve holes at two ends of the drive axle housing, and quickly performing positioning and clamping.

Description

technical field [0001] The invention relates to a clamp used in the field of mechanical processing, in particular to a tool clamp used in boring. Background technique [0002] The drive axle housing is an important part of the car, such as image 3 As shown, the bushing holes A at both ends of the drive axle case need to ensure a high coaxiality. The drive axle case is obtained from castings after boring and turning. The coaxiality of the tube hole and whether the tooling and fixture used for boring can align the axes of the casing holes at both ends of the drive axle case determine whether the machined casing holes at both ends of the drive axle case can meet the coaxiality requirements The important factor is that the existing tooling fixture used for boring the drive axle case cannot automatically align the axes of the casing holes at both ends of the drive axle casing. On the same center line, each clamping of a drive axle housing workpiece needs to be adjusted and meas...

Problems solved by technology

[0002] The drive axle housing is an important part of the car, such as Figure 3, the casing holes A at both ends of the drive axle housing need to ensure high coaxiality, and the drive axle housing is made of castings through boring, turning and other processing techniques After processing, it is necessary to ensure the coaxiality of the casing holes at both ends of the drive axle case when boring. Whether the casing holes at both ends of the drive axle casing can meet the coaxiality requirements is an important factor. The existing tooling fixture used for boring the drive axle casing cannot automatically align the axes of the casing holes at both ends of the drive axle casing. It is necessary to adjust and measure to make the axes of the bushing holes at both ends of the drive axle case basically on the same center line. Every clamping of a drive axle case workpiece needs to be adjusted and measured before it can be processed, and the work efficiency is low.
