Description

The connection part of this upper shell cover assembly of upper shell cover assembly, laser bonding and compressor
Technical field
The utility model relates to the upper shell cover assembly of a kind of compressor, particularly compressor, the connection part of this upper shell cover assembly of laser bonding and comprises the compressor of above-mentioned upper shell cover assembly.
Background technique
Compressor is the core component of chiller plant.For vertical compressor, its housing is made up of upper shell cover assembly, main casing and lower cover usually.As shown in FIG. 1 to 3, in prior art, the upper shell cover assembly of compressor is made up of lid 10 ' and sealed wiring post 20 ' usually.Lid 10 ' is provided with the mounting hole 101 ' of accommodating sealed wiring post 20 ', outlet pipe (not shown) can also be provided with, the vitreous humor 203 ' that sealed wiring post 20 ' comprises tenminal block 201 ', sealed wiring post steel seat 202 ' and tenminal block 201 ' and sealed wiring post steel seat 202 ' is tightly connected, the edge part 202a ' of the below of sealed wiring post steel seat 202 ' is provided with the shirt rim 202b ' tilted laterally.
The upper shell cover assembly of compressor in prior art, its sealed wiring post 20 ' is the bond technology adopting resistance welding formula with the connection of lid 10 ', as shown in Figure 4 (for ease of observing, sealed wiring post 20 ' illustrate only sealed wiring post steel seat 202 '), namely first sealed wiring post 20 ' is placed on lower electrode 30, sealed wiring post 20 ' is inserted in again in the mounting hole 101 ' of lid 10 ', mounting hole 101 ' is contacted with the shirt rim 202b ' of sealed wiring post steel seat 202 ', finally by the exerting pressure of mounting hole 101 ' of upper electrode 40 pairs of lids 10 ', welding machine discharges, realize being tightly connected of lid 10 ' and sealed wiring post 20 '.
In prior art, the defect of bond technology is:
1, welded structure defect: as shown in Figure 4, the sealed wiring post steel seat 202 ' of sealed wiring post 20 ' is the conical surface with the surface of contact (i.e. the internal surface of the shirt rim 202b ' of edge part 202a ') of lower electrode 30.This conical surface is adding more difficult control in man-hour, the actual size deviation about had within 3 °, can cause like this: (1) sealed wiring post 20 ' reduces with the area of contact of the conical surface of lower electrode 30, impact welding specific conductance, and the weld strength after product pressure welding; (2) not the mating of the conical surface, when upper electrode 40 pairs of upper shell cover assemblies are pressurized to a certain degree, sealed wiring post 20 ' easily produces plastic deformation, causes the destruction of the vitreous humor 203 ' to sealed wiring post 20 '.
2, resistance type welding machine pressure welding: weldment thermal distortion is larger, welding heat affected zone is also larger, due to the existence of the upper vitreous humor 203 ' of sealed wiring post 20 ', high temperature during pressure welding, vibrations easily cause breaking of vitreous humor 203 ', to the damage very large (physical strength and the temperature of glass are inversely proportional to) of vitreous humor 203 '.
3, condenser type welding machine pressure welding: weldment thermal distortion, welding heat affected zone ratio resistance formula pressure welding are much little, but be subject to the impact of " pressure welding " structure, above-mentioned conical surface matching problem cannot be escaped, and because of the discharge time of condenser type welding machine very short, about 0.02s, so it proposes higher requirement to fixture positioning precision and weldment pretreatment aspect.
Key points of quality control when sealed wiring post 20 ' pressure welding operation is factory's manufacture always, the bad scrappage caused of pressure welding rear vitreous body 203 ' is substantially 0.5% ~ 2%, if the vitreous humor 203 ' of poor sealing is dressed up complete machine directly will cause compressor leakage, cause complete machine to scrap, also easily cause security incident.How to prevent the pressure welding of sealed wiring post vitreous humor from breaking, improve conforming product rate, become a great problem of welding technique application.
