Closing tool for end socket of air cylinder

Abstract

The invention provides a closing tool for an end socket of an air cylinder. The closing tool comprises an end socket outer lining ring, a clamping device, an end socket lining film, a compression device and a runner wheel device, wherein the end socket outer lining ring supports the end socket and clings to the outer wall of the end socket, the clamping device supports and clamps the end socket outer lining ring, the end socket lining film is arranged in the end socket and clings to the inner wall of the end socket, the compression device compresses the end socket lining film towards the end socket, the runner wheel device is provided with a runner wheel used for compressing the end socket to form a closed opening, the clamping device is connected with a driving mechanism, and the driving mechanism drives the clamping device to rotate relative to the runner wheel. The closing tool mainly has the following beneficial effects: the end socket is respectively fastened internally and externally by the end socket outer lining ring and the end socket lining film, so that the end socket hardly deforms during the closing process, the straight edge part is not influenced, and the closing precision is high; only one person can implement the whole closing process, the installation and adjustment operations are simple and convenient, the closing operation carried out on one end socket can be finished within about five minutes, the production efficiency is improved greatly, and the production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a tool for closing the head of a train air cylinder. Background technique [0002] The air cylinder is a key component in the braking system of a train. The air cylinder includes the main air cylinder on the locomotive, as well as the main air cylinder and auxiliary air cylinder on the vehicle. When the locomotive starts, the wind pressure enters the main air cylinder and auxiliary air cylinder of all vehicles; when the locomotive is stopped, the air from the brake hose is released, and at this time the air pressure of the main air cylinder is lower than that of the auxiliary air cylinder, causing the auxiliary air The cylinder pushes the brake shoe, causing the brake shoe to be close to the wheel to stop the vehicle. [0003] Because its performance is superior to ordinary air cylinders, aluminum alloy air cylinders have been widely used in subways and high-speed...

AI Technical Summary

Problems solved by technology

In order to facilitate the assembly and welding of the aluminum alloy air cylinder and meet the welding performance requirements and assembly requirements, according to the EN286-4 standard, the aluminum alloy air cylinder is designed with a certain angle of closing edge, but the closing machine currently on the market is too simple. Without the inner lining mold of the head, it is difficult to control the straight side size of the head after closing. The outer diameter of the head is greatly deformed, the inclination of the straight side cannot be guaranteed, and the closing is slow, which cannot meet the quality and speed requirements.
