Embodiment Construction

[0014] exist figure 1 In the manufacturing method of the compressor hollow piston described in the present invention, the hollow head of the piston is fixedly connected to a hollow cylindrical part 2 with an open end by a sealing part 1; The cylindrical boss of the shaped part, the boss is matched with the inner wall of the hollow cylindrical part and its length is less than the length of the axial groove of the hollow cylindrical part; The hollow cylindrical part 2 of the axial end face 15, 16 has a groove 5 on the inner wall of the axial end face 15, and the hollow cylindrical part 2 of the radial end face 17, 18 of the hollow cylindrical part 2 in contact with the closure 1 There are grooves 3 on the radial end surface 17, and there are axial and radial concave grooves on the inner peripheral end surface of the hollow cylindrical component 2 on the circumferential surfaces 19, 20 of the hollow cylindrical component 2 that are in contact with the closure 1. The groove 4 of ...

Abstract

The invention discloses a method for producing a hollow piston of compressor and relative welding device, which only arranges one or more channel of exhaust channels on the joint end-face and surface of hollow piston subassembly; the welded piston subassembly can be pre-assembled into integration at the atmosphere pressure to be packaged into welding clamp in one batch. Then extracting the vacuum chamber to vacuum condition and processing electrical beam welding. Since the invention has special structure and reasonable distribution of exhaust channels, the invention can be processed easily and avoid the effect on the quality of weld seam.

Description

technical field [0001] The invention relates to a manufacturing method and welding equipment for a hollow piston used in a compressor. Background technique [0002] In the patent of invention with the application number 00135072.2, a method for manufacturing a hollow piston for a compressor is disclosed, and all processes such as assembly and welding of the method should be completed in a decompression zone. Since the assembly and welding are carried out in the negative pressure area, the manufacturing method has the characteristics of high equipment requirements, difficult operation, and relatively low efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a method for manufacturing hollow pistons of compressors and welding equipment with the characteristics of equipment under normal pressure, high production efficiency, and simple operation. [0004] In the manufacturing method of...
