Problems solved by technology

[0002] The high-speed rail brake cylinder is a component of the high-speed railway train brake. During production, it needs to perform drilling, boring and milling comprehensive cutting processing on its multiple surfaces. In order to ensure the mutual shape and position tolerance of each processing surface, it is required to complete multiple surfaces in one clamping. Processing, the existing technology uses a large horizontal five-axis machining center to cut the cylinder block of the high-speed rail brake. The large horizontal five-axis machining center is an expensive and general-purpose metal cutting processing equipment, and its processing cost is also high. The center processes high-speed rail brake cylinders in large quantities, which makes the cost of high-speed rail brake cylinders high;
[0003] Using ordinary three-axis machining centers to process high-speed rail brake cylinders requires multiple surface changes and clamping processes, and the accumulation of deviations in multiple clamping and surface changes leads to the problem that the shape and position tolerance of the product is easily out of tolerance and the processing efficiency is low; Therefore, the prior art has the problems and deficiencies of high cost, low efficiency, and easy out-of-tolerance defects

Abstract

The invention discloses a clamp device for processing a brake cylinder of a high-speed rail train, comprising a dividing head (1), a positioning clamp (2), a cylinder tail stock (3) and a pedestal. In the technical scheme, the clamp device is formed by the quarter dividing head driven and locked by a high-accuracy hydraulic valve, the positioning clamp, the cylinder tail stock and the pedestal; when in application, the positioning clamp is clamped by a dividing head clamping disc; a workpiece is clamped by the positioning clamp and is tightly pressed on the positioning clamp by means of the cylinder tail stock; and the hydraulic valve of the dividing head is driven by a numerical control milling machine to control the dividing head to drive the workpiece to be matched with the cutting of a cutting tool in a controlled mode so as to automatically rotate and change the surface. Thus, the invention overcomes the problems and defects of high cost, low efficiency and possible out-of-tolerance in the prior art, and ensures that the multi-surface processing of the brake cylinder of the high-speed rail train can be finished in one-time clamping procedure on a general numerical control milling machine through fast clamping and controlled rotation and surface changing, thereby achieving the purposes of reducing the cost, improving the efficiency and improving the product qualification rate.
