Arc striking and extinguishing plate installation tool

Abstract

The invention discloses an arc striking and extinguishing plate installation tool for installing an arc striking plate or an arc extinguishing plate. The arc striking and extinguishing plate installation tool comprises a positioning portion, a porcelain strip, a positioning plate and an elastic member, wherein the positioning portion comprises an arc striking plate mounting groove for accommodating and positioning an arc striking plate and a porcelain strip mounting groove for accommodating the porcelain strip, the porcelain strip mounting groove is located below the arc striking plate mounting groove, and the porcelain strip mounting groove and the arc striking plate mounting groove communicate with each other along the welding line direction; the porcelain strip is placed in the porcelain strip mounting groove; the positioning plate is used to prop against the end portion of the arc striking plate / arc extinguishing plate; one end of the elastic member is fixed in the arc striking plate mounting groove while the other end of the elastic member is connected with the positioning plate, the elastic member applies an elastic force to the end of the arc striking plate / arc extinguishingplate through the positioning plate, and the other end of the arc striking plate / arc extinguishing plate props against base metal to be welded. The parts of the arc striking and extinguishing plate installation tool have the advantages of simple structure, small quantity, low cost, convenient assembly and disassembly, reusability, and the like, and the welding construction of a butt-welding seamis greatly facilitated.

Description

technical field [0001] The invention relates to a tool for installing an arc striking and extinguishing plate, which belongs to the technical field of welding tools. Background technique [0002] Welded structure bogie frames are widely used in various types of railway freight cars, passenger cars, locomotives, EMUs, subways and other vehicles at home and abroad. As the basic part of the bogie, the frame integrates the parts and components on the bogie into a whole, and bears and transmits various forces and loads. Due to the complex structure of the frame and various forces and loads, there are very strict requirements on the welding of the frame. The welding quality of the weld directly determines the performance of the frame. Butt welds are widely used in beam assembly welding to connect the entire frame into a whole. [0003] In the frame welding structure, important welds, especially butt welds are commonly used in the assembly welding of frame components. In order to...

AI Technical Summary

Problems solved by technology

The arc-starting and arc-resting plates need to be cut off after welding. Due to the influence of welding deformation, it is very easy to cut off the main body of the component when cutting off the arc-starting and arc-resting plates, which affects the quality of the structure.

[0005] The existing arc starting and resting plates that are independent of the base metal need to be installed flat with the base metal and in good contact with the base metal. The installation of the arc starting and resting plates is time-consuming and laborious, and the installation quality is unstable
