Abstract

The invention relates to the technical field of automobile part manufacturing, in particular to a rear axle support drilling device. The rear axle support drilling device further comprises a supporting base located on the outer side of an air cylinder support. The supporting base is provided with a limiting disc. The air cylinder support is composed of a bottom plate, a left limiting plate and a right side plate. The right side plate is provided with drill bit via holes. The upper portion of the left limiting plate and the upper portion of the right side plate are fixedly connected with the lower portion of the bottom plate, and the left limiting plate and the right side plate are fixed to the support. According to the device, the supporting base is additionally arranged and staggered from the air cylinder support, and drill bits cannot be affected accordingly; the supporting base is provided with the limiting disc, the limiting disc is matched with a circular hole in a rear axle support, when a pressing air cylinder conducts downward pressing, the circular hole in the rear axle support is right formed in the limiting disc in a sleeving manner, and therefore tight fixing can be achieved; and the left limiting plate can limit the left side of the rear axle support, the rear axle support can be prevented from moving leftwards in the drilling process, and the drilling precision is guaranteed.

Description

technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to a rear axle shaft support drilling device. Background technique [0002] After the rear axle bracket is formed, it needs to be put into the CNC machine tool to process four mounting holes and a center hole. On one side of these mounting holes, several connecting holes need to be drilled to fix the vehicle. Traditional processing The mode of connecting hole is to process successively on drilling machine, because connecting hole is at least two, thereby needs to process twice on drilling machine, needs twice to fix rear axle support, wastes time and energy. For this reason, the applicant has applied for a rear axle shaft support drilling device, application number: 201410503213.6, which includes a bracket, a compression cylinder, a first motor, a reduction box and a second motor; the compression cylinder is fixed on the cylinder On the bracket, the cylinder bracke...
