It is featured as connecting piston base with rotary slope disc in compressor and moving closed hollow cylinder in hole of air cylinder of compressor reciprocally, seal-connecting the first component of piston with the second component, welding connection periphery of two said component of piston by consumable electrode argon arc welding to form two said components to be an integral unit.
Description
Technical field
The present invention relates to a kind of hollow piston in compressor and manufacture method thereof, this box type piston is used for inclined disc type variable compressor.The present invention adopts the piston of the band hollow cylinder of aluminum alloy manufacturing can satisfy the weight requirement that reduces piston, reaches requirement of strength.
Background technique
Piston is reciprocating parts, wishes to reduce its weight.For reducing the size of compressor, need to strengthen the rotating speed of live axle, also need to reduce the weight of piston.In addition, in inclined disc type variable compressor, in order stably to regulate the tilt angle between swash plate and the live axle, and reduce the noise in the compressor operation process, need reduce the weight of piston especially.
Have at present and adopt laser beam welding, electron beam welding, friction welding, be threaded etc. method is made box type piston.These methods all have the following disadvantages.
1, Chinese patent publication number CN1290814A discloses the employing electron beam, laser beam comes the welding processing box type piston.This method equipment investment is very big, the processing charges height.And the bridging of weld seam is poor, easily produces pore.
2, Chinese patent publication number CN1374453A and CN1245264A disclose the employing friction welding and have processed box type piston.This method can make and produce flange in the hollow piston cylinder body, has increased the weight of piston.In addition, flange comes off in the compressor process sometimes, influences the compressor operating dynamic balancing.
3, Chinese patent publication number CN1619148A discloses and has adopted the manufacturing box type piston that is threaded.When this method is made,, so just increased the weight of piston for proof strength need increase the wall thickness of hollow cylinder.In addition, the manufacturing efficiency of this method is also lower.
Summary of the invention
The object of the present invention is to provide a kind of piston cheaply, simultaneously, the present invention also provides the manufacture method of this piston.
Realize that technological scheme of the present invention is:
Piston is made up of the piston seat and the hollow cylinder of dribbling face groove, wherein a certain circumference of piston along hollow cylinder is separated, and the part that comprises piston seat is called first parts, and remaining part is called second parts.According to the position difference of cutting apart circumference, first parts can comprise piston seat, or the part of piston seat and hollow cylinder, also can be the hollow cylinder body portions of piston seat and band opening.First parts and second parts are tightly connected and make it form a hollow cylinder.The described method that is tightly connected can be to be provided with the sealed attachment part at least one face of the joint of two parts.Or the interference drive fit of two parts by the inside and outside circle side face formed be tightly connected.After being tightly connected, on the circumference of first parts and the second parts joint with the method for metal argon arc welding or argon tungsten-arc welding with the two parts piston that is welded into a whole.
The box type piston intensity height that adopts the present invention to make, the welding equipment investment is little, low cost of manufacture, the manufacturing efficiency height, steady quality, and processing method is simple, realizes easily, is fit to auto parts machinery and produces characteristics in enormous quantities.

Embodiment
Fig. 2 to Fig. 5 is four embodiments shown in hollow piston in compressor of the present invention and the manufacture method thereof.First parts and second parts are integrally welded with two parts near engaging on the circumference of the end of the hollow cylinder of piston seat among Fig. 2.First parts among Fig. 3 and second parts are integrally welded with two parts engaging on the circumference of the bottom end face of hollow cylinder.First parts among Fig. 4 engage on a certain circumference of hollow piston cylinder body with second parts, and it is integrally welded.First parts among Fig. 5 engage on a certain circumference of the bottom end face of hollow piston cylinder body with second parts, and it is integrally welded.Welding adopts metal argon arc welding or tungsten argon arc soldering method to realize.Described metal argon arc welding is the direct current metal argon arc welding, pulse metal argon arc welding and the collaborative pulse modulated pulse metal argon arc welding of band low frequency; Argon tungsten-arc welding is meant ac tungsten inert gases welding and pulse ac argon tungsten-arc welding; When argon tungsten-arc welding, a kind of method is to adopt filler wire, and another kind of method is to adopt mother metal from molten.
As Fig. 6, shown in Figure 8, at first parts and the second parts joint sealed attachment part is housed, can between first parts and second parts, apply an external force by the axial direction along hollow cylinder, guarantee sealing good in whole welding process.
As shown in Figure 7, box type piston first parts and second parts adopt the interference drive fit.Can realize sealing good in the whole welding process equally.
The present invention is suitable for the application example of two pistons of time processing equally, as Fig. 9, shown in Figure 10.
