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
The present invention relates to a kind of manufacture method and welding equipment that is used for the hollow piston of compressor.
Background technology
Disclose the manufacture method of a kind of compressor with the hollow form piston in application number is 00135072.2 patent of invention, operations such as assembling that this method is all and welding all should be finished in depressor area.This manufacture method is because assembling and be welded in the negative pressuren zone and carry out, and brings equipment requirement height, characteristics such as operation easier is big, efficient is relatively low.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of have under the normal pressure of being equipped in carry out the manufacture method and the welding equipment of the compressor hollow piston of production efficiency height, characteristics such as simple to operate.
The manufacture method of compressor hollow piston of the present invention, the hollo head of piston is by being fixedly connected on a closure member one at least on the hollow cylindrical member of an end opening at two ends; Described closure member has the cylindrical boss of the hollow cylindrical member of stretching into, this boss cooperate with the inwall of hollow cylindrical member and its length less than the length of hollow cylindrical member axial notch; Fluted on fluted on described hollow cylindrical member and the contacted axial end of closure member, radial end face, on circumference, have connection shaft to the groove of radial groove, thereby the hollow space that makes described hollow cylindrical member connect the hollow piston that the back forms with closure member has the exhaust passage; Hollow cylindrical member and closure member are connected into one; The electron beam welding operation is welded into a whole all coupling parts of piston component in negative pressuren zone by welding equipment.
On the one end inwall of the required sealing of described hollow cylindrical member the groove that extends to openend internally can be arranged, on the end face of one end of the required sealing of described hollow cylindrical member the groove that runs through the hollow cylindrical member wall thickness can be arranged, can be useful on the circumference of the openend inwall of described hollow cylindrical member be communicated with the hollow cylindrical member wall on have axially and the groove of radial groove, thereby make and form at least one exhaust passage on the hollow cylindrical member, or adopt and use the same method, can with three kinds of exhaust passages simultaneously or a part be distributed in hollow cylindrical member on the end face and periphery of the closure member that engages.
Described electron beam welding operation comprises step, be clamped in a plurality of pistons to be welded that assembled in the anchor clamps respectively, then whole weld jig is put into the welding booth, make the welding booth become negative pressure state with the vacuum extractor extracting air, because there is the exhaust passage commissure of piston to be welded, so can in vacuum chamber, finish vacuum requirements together to cavity, start the welding procedure workpiece after circling, welder's part and workpiece to be welded switch again, finish up to whole workpiece welding to be welded, the anchor clamps of finishing welding are taken out in vacuum chamber, finish welding; Described anchor clamps have rotation and two functions of revolution; Described piston is in the only rotation but do not revolve round the sun of when welding piston.
Welding equipment of the present invention is made up of electron beam gun, vacuum chamber and weld jig, vacuum extractor.
Manufacture method according to above-mentioned described compressor hollow piston has characteristics such as technology is simple, cost is low.
