Embodiment Construction

[0016] Such as figure 1 As shown, the present invention provides a self-centering expansion welding fixture, including: a clamp body 1, a centering tension ring 2, a fixed guide rail 3, a pull rod 4, a spring 5, an air pipe 6, a cylindrical thin-walled part 7, a cylinder Shaped thin-walled parts 8, slider 9, screw 10. Such as figure 1 As shown: Part 1 is the clamp body, which cooperates with the cylindrical thin-walled part 8 to play a rough positioning role; the material of the centering tensioning ring 2 is copper to prevent the bonding of the part and the fixture; the slider 9 and the centering tensioning ring 2 Use screws 10 to connect and fix. Pull rod 4 moves downwards and its side cone pushes slide block 9 to move outwards along fixed guide rail 3, so that cylindrical thin-walled cover 7 and cylindrical thin-walled tube 8 are centered and tightened simultaneously. Pass into shielding gas from vent pipe 6, carry out welding. After the welding is completed, the pull r...

Abstract

The invention belongs to the field of clamps, and relates to an automatic centering and expanding welding clamp. The clamp comprises a clamp body, a ventilation pipe and a locating device. The locating device comprises a centring and expanding ring, a fixed guide rail, a pull rod with a wedge face, elastic parts and a sliding block. The welding clamp capable of achieving automatic centring, expanding and rapid and automatic separating and dismounting on barrel-shaped thin-walled parts is designed, and meanwhile the clamp has the effects of avoiding weld joint oxidization and adhesion of the barrel-shaped thin-walled parts and the clamp.

Description

technical field [0001] The invention belongs to the field of fixtures and relates to a self-centering expansion welding fixture. Background technique [0002] For welding cylindrical thin-walled parts, there are difficulties in positioning, clamping and assembling before welding; it is easy to deform during welding, the weld is easy to oxidize, and it is difficult to disassemble the fixture after welding. Therefore, it is necessary to use welding fixtures to ensure the welding accuracy of parts. Contents of the invention [0003] The purpose of the present invention is to design a welding fixture that can realize automatic centering, tensioning, and quick automatic separation and disassembly of cylindrical thin-walled parts, and at the same time has the effect of preventing weld oxidation and cylindrical thin-walled parts from sticking to the fixture . [0004] The invention provides a self-centering expansion welding fixture, which includes: a clamp body, a vent pipe an...
