Brake cylinder hydraulic clamp capable of meeting multiple machining procedures

Abstract

The invention discloses a brake cylinder hydraulic clamp capable of meeting multiple machining procedures. Positioning bases are arranged on a bottom plate, and positioning planes for positioning thearc surfaces of the bottoms of brake cylinders and positioning blocks acting with the front side surfaces of the brake cylinders are arranged on the positioning bases; the positioning bases are further hinged to inclined column tight pressing plates, the inclined column tight pressing plates are connected with a hinge mechanism, wherein the hinge mechanism is driven by a first driving source, theinclined column tight pressing plates are in linkage with the hinge mechanism and act on the rear side surface of the brake cylinders, so that the inclined column tight pressing plates cooperate withthe positioning blocks to limit angular freedom degree of the brake cylinder; and the hydraulic clamp is further provided with axial positioning blocks, a second driving source for driving the axial positioning blocks to ascend or descend is arranged on the bottom plate, the axial positioning blocks are used for carrying out axial positioning on the brake cylinders after ascending, and shaft end positions of the brake cylinders are emptied after the axial positioning blocks descending. According to the clamp, full-sequence machining process is completed under one-time clamping, so that processing manufacturability is improved, and the equipment configuration is more flexible.

Description

[0001] The patent application of the present invention is a divisional application of the invention title "a hydraulic fixture for processing brake wheel cylinders and a method for processing brake wheel cylinders". The application date of the original application is January 13, 2017, and the application number is 2017100235532 . technical field [0002] The invention relates to a hydraulic clamp, in particular to a hydraulic clamp for processing brake wheel cylinders. Background technique [0003] At present, the machining process of the brake wheel cylinder is as follows: the first sequence of CNC lathe machining the step mounting surface of the cylinder block; the second sequence of CNC lathe processing the cylinder hole and both ends of the cylinder hole with the step mounting surface of the cylinder block; Each small hole is processed by the type machining center. In the above-mentioned machining process, the workpiece needs to be clamped 3 times to complete the full-s...

AI Technical Summary

Problems solved by technology

In the above-mentioned machining process, the workpiece needs to be clamped 3 times to complete the full-sequence machining process, and the first sequence process needs to be equipped with 2 sets of equipment, the second and third processes need to be equipped with 1 set of equipment, and a total of 4 sets of equipment are required to be equipped. Effectively balance the processing cycle time of each process; when machining the cylinder hole in the second step of the machining process, due to the equipment performance limitation of the CNC lathe, the spindle speed is not high enough to meet the roughness requirements of the machined cylinder hole, forcing the workpiece to be processed in the first step. After the completion of the third sequence, an additional sequence of honing process is required to ensure the roughness of the cylinder bore of the workpiece
