Abstract
The present invention relates to a forming method for a hollow head of a compressor piston, particularly to a forming method for a hollow piston of an air conditioner compressor of automobiles. The hollow head of the piston is manufactured by that a sealing part is fixedly connected to a hollow cylindrical component with at least one of two ends opened so as to seal the opened end of the hollow cylindrical component, wherein the fixed connection is implemented by argon arc weld, projection weld or screw connection. The method of the present invention has the characteristics of high efficiency and simple operation.
Description
Technical field
The present invention relates to a kind of by a closure member being welded to one at least on the hollow cylindrical member of the end opening in the two ends, thereby seal the opening end of this hollow cylindrical member, and be formed for the method for hollo head of the piston of compressor, relate in particular to the formation method of the box type piston of automobile air conditioner compressor.
Background technique
The inventor is that 01111932.2 formation method that is called the hollow header of piston that is used for swash-plate-type compressor discloses a kind of transmitted beam and can weld closure member is fixed to hollow cylindrical member at application number.It is higher that this bundle can be welded into.
Summary of the invention
The object of the present invention is to provide a kind of closure member to be fixed to method on the hollow cylindrical member, this fixation method cost is low, easy to operate, guarantees that there is the favorable mechanical performance piston joint.
The formation method of the hollow header of piston of compressor of the present invention under the effort that reduces piston weight, has proposed to make the piston with hollo head.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, thereby seals the opening end of this hollow cylindrical member and make; Described two parts that are in contact with one another have concentricity, and by rotate the welding of finishing whole circle circumferential weld in anchor clamps, described welding method is argon arc welding.
Described hollow cylindrical member can be to comprise diapire and the cylindrical section that extends vertically from the diapire circumference; Described closure member can be the cylindrical section that comprises the attachment portion that is connected with reciprocating drive mechanism and the end is arranged, and both are in aggregates; Described hollow cylindrical member opening end end face contacts with the end face of closure member cylindrical section and is connected; The excircle of the end face of the cylindrical section of described closure member extends to form a mounting portion vertically, and the inner peripheral surface of the external peripheral surface of mounting portion and the cylindrical section of hollow cylindrical member is fitted to each other; Argon arc welding connects can metal argon arc welding or non-melting electrode argon arc welding.
Described hollow cylindrical member opening end inner circumferential surface has internal thread, the extension external peripheral surface of the closure member of Pei Heing has the outside thread that matches with internal thread with it, and is bonding by the outer surface that is extruded with the hollow cylindrical member that is threaded or the adding additives that is threaded then.
Be extended with continuous or interrupted triangular shaped cylinder on the hollow cylindrical member opening end end face, this leg-of-mutton top contacts with the outer circumference portion branch of closure member cylinder part end face, and connects by the projection welding of resistance welding.
Adopt the present invention to connect the beneficial effect of the method for closure member and hollow cylindrical member: have production product efficiency height, easy to operate, the characteristics that cost is low.

Embodiment
The present invention is further elaborated below in conjunction with accompanying drawing:
In accompanying drawing 1, the hollo head of piston is by being fixedly connected on a closure member 1 on the hollow cylindrical member 2 of an end opening, thereby seals the opening end of this hollow cylindrical member and make; Closure member 1 is to comprise the attachment portion that is connected with reciprocating drive mechanism, the attachment portion is in aggregates with the cylindrical section that has diapire and extend vertically along the diapire excircle, the end face of the end face of the cylindrical section of closure member 1 and the cylindrical section of hollow cylindrical member is in contact with one another, the cylindrical section end face inner circumferential portion of closure member 1 extends axially the cylindricality mounting portion, and the external peripheral surface of this mounting portion cooperates with the inner circumferential surface at the place, cylindrical section end of cylinder, and the end face of contact connects closure member and hollow cylindrical member by metal argon arc welding.
In Fig. 2, the end face of contact is to connect closure member 1 and hollow cylindrical member 2 by non-melting electrode argon arc welding, in order to guarantee welding reliability, the phenomenon of avoiding the appearance of weld seam to concave, place, end that closure member and hollow cylindrical member are in contact with one another is by extruding or be processed to form radially the flange of extension, welds by non-melting electrode argon arc welding then.
In Fig. 3, the external peripheral surface of closure member 1 mounting portion has outside thread to be connected with the screw-internal thread fit of the cylindrical section end inner circumferential surface of cylinder, then by the be threaded outer surface of part of extrusion cylinder, the tightness and the reliability that increase to connect.
In Fig. 4, the opening end end face upper edge of described hollow cylindrical member extends axially into the cylinder of numerous adjacent in twos triangular shaped formations, leg-of-mutton top contacts with the end face of closure member cylindrical section excircle part, and described closure member 1 is connected with the projection welding of hollow cylindrical member 2 by resistance welding.
