Railway wagon brake pipe system joint body all-position welding device

Abstract

The invention discloses a railway wagon brake pipe system joint body all-position welding device, belongs to welding production equipment, and in particular relates to a welding device of a long and large brake pipe system. The railway wagon brake pipe system joint body all-position welding device comprises a support platform. The key technology is that a pneumatic three-jaw chuck and a rotary platform driven by a direct-current motor are fixedly installed on the support platform; the rotary platform and the pneumatic three-jaw chuck are coaxial, and the rotary platform rotates relative to the pneumatic three-jaw chuck; a pneumatic V-shaped clamping component is arranged in a position on the support platform, which is corresponding to the pneumatic three-jaw chuck; and an auxiliary bracket is arranged in a position corresponding to the pneumatic V-shaped clamping component. According to the invention, a brake pipe system can be welded in a convenient, safe and labor-saving way in all positions; the positioning accuracy is high; the production safety is ensured; the welding quality is high; unqualified products are reduced; and the production efficiency is high.

Description

technical field [0001] The utility model relates to an all-position welding device for a joint body of a brake pipe system of a railway freight car, which belongs to welding production equipment, in particular to welding equipment for a large brake pipe system. Background technique [0002] The braking system of railway freight cars in my country uses compressed air as the braking source power, and operates and controls the train operation by changing the air pressure. The brake system is mainly composed of various control valves, brake piping, and basic braking devices. The brake piping is used to transmit compressed air. The brake piping is mainly welded by the pipe and the joint body, and then connected with fasteners. onto the car body. [0003] At present, vertical welding is adopted for brake pipe welding, and the clamping and positioning of the pipe and joint body is simple. Although the welding seam welding position is good, it is difficult to ensure the verticality...

AI Technical Summary

Problems solved by technology

[0003] At present, vertical welding is adopted for brake pipe welding, and the clamping and positioning of the pipe and the joint body is simple. Although the welding position of the weld seam is good, it is difficult to ensure the verticality and coaxiality of the pipe fitting and the joint body.

At the same time, there are the following problems for vertical welding: it is difficult to load and unload long pipe fittings, and the operator needs to repeatedly move the pipe with a length of about 5 meters and a weight of 15 kg from a horizontal state to a vertical state, and then lay it flat after welding. The labor intensity is high, it is difficult to control, and the pipe is easy to fall and cause safety accidents; in addition, because the welding operation is carried out indoors, there is a crane traveling in the room, and the too long pipe will interfere with the crane after it is placed vertically, and it is easy to cause safety accidents
