Brake cylinder seat assembly tool

Abstract

The invention discloses a brake cylinder seat assembly tool which comprises a bottom plate, a limiting plate, a first limiting block and a second limiting block. A rectangular connecting plate assembling groove is formed in the middle of the upper surface of the bottom plate, and two mutually parallel seat plate assembling grooves are formed in the position between the connecting plate assemblinggroove and the end part of the bottom plate; the limiting plate is arranged at the end, far away from the seat plate assembling grooves, of the bottom plate, the end part of the limiting plate is integrally connected with an upward protruding limiting convex part, and the inner side edge of the limiting convex part is attached to the end part of the bottom plate; the first limiting block is fixedly connected to the tail end of the limiting plate and is perpendicular to the limiting plate, the outer side surface of the first limiting block is kept flush with the end part of the limiting plate,all parts of the welded brake cylinder seat can be effectively mechanically fixed, a welding seam is always in a mechanically fixed state during welding, deformation caused by welding is effectively prevented and absorbed, the quality of the welding seam is improved, and the precision of a welded workpiece is high, and the manual labor intensity is also reduced.

Description

technical field [0001] The invention belongs to the technical field of assembly and welding of a brake cylinder seat of a bogie of an engineering model work vehicle, and in particular relates to a tool for assembling a brake cylinder seat. Background technique [0002] The brake cylinder seat of the bogie of the engineering vehicle operation vehicle is an asymmetric open structure composed of two seat plates and a connecting plate. The seat plate is low carbon steel with a plate thickness of 14mm, and the connecting plate is low carbon steel with a plate thickness of 10mm. . Since there is no break in each component during welding, double-sided fillet welding is adopted, and multi-layer and multi-pass welding is used in order to reduce welding deformation. The drawing design requirements of the brake cylinder block are high, its shape and position tolerance, flatness and verticality are required to be within 1mm, the linear tolerance is within 1mm, and the size of the inter...

AI Technical Summary

Problems solved by technology

The drawing design requirements of the brake cylinder block are high, its shape and position tolerance, flatness and verticality are required to be within 1mm, the linear tolerance is within 1mm, and the size of the internal file is 0-1mm. The strict requirements have led to the occurrence of existing butt welding processes. Welding deformation, the defect that the brake cylinder seat after welding cannot meet the size requirements
