Partitioned side wall friction stir welding integration universal fixture

Abstract

The invention discloses a partitioned side wall friction stir welding integration universal fixture, and relates to the technical field of subway vehicle side wall auxiliary welding equipment. The partitioned side wall friction stir welding integration universal fixture comprises a fixture body, a movable compression mechanism, a plurality of horizontal compressors, a plurality of C-shaped clampsand a plurality of vertical compressors, wherein the fixture body comprises a plurality of beams arranged in a parallel mode, a plurality of girders arranged in a parallel mode, a plurality of laterallimiting plates, a plurality of horizontal compressor mounting seats, a plurality of vertical compressor mounting seats and a plurality of connection seats, and the movable compression mechanism comprises a plurality of door-shaped frames, a vertical lead screw mechanism and two linear guide rails. By using the partitioned side wall friction stir welding integration universal fixture, a worker only needs to complete one-time clamping and fixing operation for the partitioned side wall friction stir welding integration universal fixture and an operation platform, and then the partitioned side wall friction stir welding integration universal fixture can adapt to clamping and positioning requirements of all wall board welding steps, the worker only needs to clamp the operation platform on different positions of the partitioned side wall friction stir welding integration universal fixture in different welding steps, time and labor are saved, and work efficiency of side wall friction stir welding is greatly improved.

Description

technical field [0001] The invention relates to the technical field of welding auxiliary devices for side walls of subway vehicles, in particular to a universal fixture for friction stir welding integration of block side walls. Background technique [0002] Such as Figure 1 to Figure 3 As shown, the side wall 13 of the subway vehicle is made up of No. 1 wallboard 13-1, No. 2 wallboard 13-2, No. 3 wallboard 13-3 and No. 4 wallboard 13-4, wherein, No. 1 wallboard 13 -1 is a wall panel with a radian, and the other wall panels are straight wall panels. Using the friction stir welding technology to complete the welding of the side wall 13 needs six steps: the front welding of the No. 1 wall panel 13-1 and the No. 2 wall panel 13-2; the No. 1 wall panel 13-1 and the No. 2 wall panel 13-2 The reverse welding of No. 3 wall panel 13-3 and No. 4 wall panel 13-4; The reverse side welding of No. 3 wall panel 13-3 and No. 4 wall panel 13-4; No. 1 wall panel that will complete the weldi...

Problems solved by technology

[0004] In order to solve the welding process of existing welding fixtures, multiple fixtures need to be used together, resulting in a large storage space for the fixtures, and frequent disassembly and assembly of the fixtures during welding, resulting in cumbersome operation steps, long welding time, low work efficiency, and frequent disassembly The fixture will reduce the service life of the fixture, and every time the fixture is installed, it needs to be adjusted, which is a time-consuming and laborious technical problem. The present invention provides a universal fixture for friction stir welding of block side walls
