Press fitting-disassembling integrated tool for bogie rotary arm node rubber sleeve

Abstract

The invention discloses a press fitting-disassembling integrated tool for a bogie rotary arm node rubber sleeve. The integrated tool comprises a press head, a positioning disassembling seat and a supporting seat, wherein the height of the press head can be increased and decreased; the supporting seat is arranged on one side of the positioning disassembling seat; a central through hole is formed in the positioning disassembling seat, and the hole diameter of the central through hole is larger than the outer diameter of the rotary arm node rubber sleeve; the top of the positioning disassembling seat is coaxially provided with a removable limit ring, and the inner diameter of the limit ring is smaller than the outer diameter of the inner wall of a rotary node hole; the section of the limit ring is in an L shape, and the top of the limit ring can extend into a rotary node hole and be attached to the inner wall of the rotary node h ole. By adopting the structure, only one set of the tool can achieve press fitting and disassembling of the bogie rotary arm node rubber sleeve, the manufacturing cost is low, and the wide application and popularization value is achieved. In addition, a positioning rotary arm can be effectively supported, the concentricity of the rotary arm node hole and the rotary arm node rubber sleeve is high, the press fitting or disassembling precision is high, and the rotary node hole is not prone to being damaged.

Description

technical field [0001] The application relates to an auxiliary tooling in the production process of a bogie, in particular to a tooling integrating press-fitting and dismounting of a rubber sleeve at a pivot arm node of a bogie. Background technique [0002] Bogies, such as the PW-220K bogies produced by our company, have also become the main type of bogies for 25T passenger cars. As of the end of 2014, 1,400 vehicles have been installed, and the use of them will continue to increase. [0003] The continuous application of bogies brings new problems. As stipulated in the passenger car maintenance regulations newly issued by our company, it is required to repair and update the rubber sleeves of the joints of the pivot arm. [0004] However, at present, there is no tooling equipment for pressing and unloading the rubber sleeve of the PW-220K bogie jib node in the domestic depots and a convenient and effective process. At the same time, the tooling used by the factory in the ...

AI Technical Summary

Problems solved by technology

[0004] However, at present, there is no tooling equipment for pressing and unloading the rubber sleeve of the PW-220K type bogie jib node rubber sleeve and a convenient and effective process in every depot in China.

At the same time, the tooling used by the factory in the early stage can only be used for press-fitting work, and it cannot effectively support the boom. The joint hole of the pivot arm is not concentric with the rubber sleeve of the pivot arm. After pressing, the joint hole of the pivot arm often has strain, which is inconvenient to use high manufacturing cost
