Abstract
The invention relates to a piston electron beam welding method, which comprises the following steps: 1, a piston is cleaned and press mounted; 2, the piston is horizontally fixed on a fixture capable of autorotating, the fixture and the piston enter a vacuum chamber, and simultaneously the vacuum chamber is vacuumized; 3, an electron beam is vertically aligned to a welding seam of the piston downwards, and moves circularly by taking the center of the welding seam of the piston as the center of a circle and taking the width of the welding seam of the piston as a diameter, and simultaneously the piston autorotates through the fixture to weld the circumferential welding seam of the piston; and 4, the fixture provided with the piston is moved out of the vacuum chamber, and the piston is disassembled to complete the welding of the electron beam of the piston. In the piston electron beam welding method, the electron beam moves circularly by taking the center of the welding seam of the piston as the center of a circle and taking the width of the welding seam of the piston as a diameter, and in the stirring process of the electron beam, bubbles in liquid metal can be broken and discharged, bubbles in the welding seam can be effectively avoided, the rejection rate of the piston is reduced, and the production cost is reduced.
Description
Technical field
The present invention designs the electron beam welding field of compressor of air conditioner piston, especially a kind of piston electro-beam welding method.
Background technology
Shown in the weld seam of compressor of air conditioner piston such as the A of Fig. 1; In the industry electron beam welding is all adopted in the welding of compressor of air conditioner piston at present; And in electron beam welding process; Because the certain impact power of electron beam has certain stirring to molten metal liquid, cause that there is a spot of bubble easily in weld seam inside when cooling.These a spot of bubbles then can cause the serviceability of piston to descend, and piston breaks down easily, further influences the operate as normal of compressor.Often this type piston need be looked into when check and remove, and as substandard product, has so just reduced the yield rate of piston electron beam welding, thereby has improved the processing cost of piston.
Summary of the invention
The objective of the invention is provides a kind of bubble residual in the weld seam of effectively eliminating for the deficiency that solves above-mentioned technology, improves the piston electro-beam welding method of electron beam welding yield rate.
In order to achieve the above object, the piston electro-beam welding method that the present invention designed, the first step: piston is cleaned and press-fits; Second step: piston be horizontally fixed on can the anchor clamps of rotation on, anchor clamps and piston entering vacuum chamber vacuumize vacuum chamber simultaneously; The 3rd step: electron beam is aimed at the weld seam of piston straight down and is the center of circle with the center of the weld seam of piston, is that diameter is made circular motion with the width of piston weld seam, and piston is made spinning motion through anchor clamps simultaneously, can realize the welding to the piston circumferential weld; The 4th step: shift out vacuum chamber to the anchor clamps that piston is housed, unload lower piston, promptly accomplish electron beam welding to piston.
The resulting piston electro-beam welding method of the present invention, in vacuum chamber, electron beam is vertically aimed at the weld seam of piston, utilizes anchor clamps to drive the piston rotation, realizes the whole disposable welding to the piston circumferential weld.Electron beam is the center of circle with the center of piston weld seam simultaneously; Width with the piston weld seam is that diameter is made circular motion, in the electron beam agitation, can let bubble in the molten metal break and discharge; Can effectively avoid existing in the weld seam bubble; Reduce the percent defective of piston, reduce production costs, and can improve the serviceability of piston.

Fig. 1 is the structure of piston sketch map.
The specific embodiment
Through embodiment the present invention is done further description below.
Embodiment 1:
The piston electro-beam welding method that present embodiment is described, i.e. method: the first step: piston is cleaned and press-fits to welding through electron beam shown in the A of the weld seam of piston such as Fig. 1; Second step: piston be horizontally fixed on can the anchor clamps of rotation on, anchor clamps and piston entering vacuum chamber vacuumize vacuum chamber simultaneously; The 3rd step: electron beam is aimed at the weld seam of piston straight down and is the center of circle with the center of the weld seam of piston, is that diameter is made circular motion with the width of piston weld seam, and piston is made spinning motion through anchor clamps simultaneously, can realize the welding to the piston circumferential weld; The 4th step: shift out vacuum chamber to the anchor clamps that piston is housed, unload lower piston, promptly accomplish electron beam welding to piston.
