Drum spring press-fit tool for parking cylinder

Abstract

The invention discloses a drum spring press-fit tool for a parking cylinder. The drum spring press-fit tool comprises a bottom plate for placing a cylinder body of the parking cylinder and a mountingplate arranged above the bottom plate, wherein the cylinder body of the parking cylinder can be fixedly connected with the mounting plate after being placed on the bottom plate; two guide posts whichare symmetrically arranged are arranged on the two sides of the top of the mounting plate; a guide plate capable of sliding on the two guide posts in a reciprocating manner is sleeved between the twoguide posts; and a limiting block positioned between the guide plate and the mounting plate is also sleeved on each guide post. The drum spring press-fit tool has the advantages that the structural design is ingenious, the assembly, disassembly and compression are very convenient, the safety and reliability are very high, the cylinder body and a cylinder cover of the parking cylinder can be kept in a correct mounting posture in the press-fit process of a drum spring, the drum spring press-fit tool is conveniently matched with a unit cylinder intermediate body for mounting, the assembly accuracy is greatly improved, the assembly quality is guaranteed, the overall size can be reduced to meet the requirement of an assembly production line, the drum spring press-fit tool can also be used on anautomatic assembly line of the parking cylinder, and the working efficiency is further improved.

Description

technical field [0001] The invention relates to an auxiliary tool for assembling a parking cylinder of a brake caliper for a railway vehicle, in particular to a drum-shaped spring press fitting tool for a parking cylinder, which belongs to the technical field of mechanical tooling fixtures. Background technique [0002] When the parking cylinder of a railway vehicle is installed, because the drum spring provides the braking force when the vehicle is parked, the spring force of the drum spring is relatively large, and it is difficult to press and install; The principle of the lead screw is to design the tooling to press the drum spring. When pressing, the screw is manually rotated to convert the rotation of the screw into a downward press movement. Although this method or tooling can be used to press the drum spring Press-fitting, but this method is labor-intensive, labor-intensive, and unsafe; at the same time, the volume of the tooling is generally relatively large, and the...

[0002] When the parking cylinder of a railway vehicle is installed, because the drum spring provides the braking force when the vehicle is parked, the spring force of the drum spring is relatively large, and it is difficult to press and install; The principle of the lead screw is to design the tooling to press the drum spring. When pressing, the screw is manually rotated to convert the rotation of the screw into a downward press movement. Although this method or tooling can be used to press the drum spring Press-fitting, but this method is labor-intensive, labor-intensive, and unsafe; at the same time, the volume of the tooling is generally relatively large, and the press-fitting posture of the drum spring cannot be guaranteed, the production efficiency is also low, and it is not easy to install in an automated assembly line. Realized above, which limits the realization of automatic installation of the whole set of parking cylinders
