A welding equipment suitable for valve manufacturing

Abstract

The invention provides a welding equipment suitable for the production and manufacture of valves, including a support device; two first mounting plates are fixedly connected to the bottom of the support device, ten support columns are installed on the support device, and the ten support columns are fixed The running track is connected; four positioning devices are fixedly connected to the supporting device, and the structures on the four positioning devices are the same; the driving device is installed on the running track, and the adjusting part is installed on the driving device; the driving device is installed with The upper mold positioning device; the welding support part, which is rotatably connected to the driving device; the welding part is installed on the welding support part, and the positioning device is installed, and the propulsion can be realized by rotating and positioning the propulsion shaft. The structure is simple and stable. By adjusting the four positioning propulsion shafts, the coaxiality of the valve parts and the running track can be adjusted, which effectively improves the welding accuracy of the valve, greatly reduces the defective rate, and avoids the occurrence of "virtual welding" at the same time.

Description

technical field [0001] The invention belongs to the technical field of valve production, and more specifically relates to welding equipment suitable for valve production and manufacture. Background technique [0002] Valves are the control components in the fluid delivery system. They have the functions of cut-off, adjustment, diversion, prevention of reverse flow, pressure stabilization, diversion or overflow pressure relief. Valves can be used to control air, water, steam, various corrosive media, mud, etc. Due to the important role of valves in the flow of various types of fluids such as oil, liquid metal and radioactive media, the assembly and welding of valves is particularly important. At this time, welding equipment for valve manufacturing must be used to assist in the completion Valve welding work. [0003] For example, the application number: CN201811457614.7 involves automatic valve welding equipment, including electric push rod, turntable, main shell, screw, moto...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a kind of welding equipment suitable for valve production and manufacturing, to solve the problem that the existing welding equipment for valve production and manufacturing does not have a welding coaxial fixing structure, and the valve assembly starts welding when the basic assembly of the valve assembly is not in place. The service life of the valve is greatly reduced, and the inaccurate butt joint of the valve components leads to "false welding" in the welding, which increases the defective rate; there is no ring valve welding device, and the welding position needs to be adjusted frequently, resulting in the inability to quickly weld the valve work, the welding speed is slow, which affects production efficiency; the welding torch positioning structure is not set, and the welding position required by different valves cannot be met. While the welding limitations are large, the inability to accurately adjust the welding angle of the welding torch will reduce the quality of the welding process.
