Abstract

The utility model relates to a matching structure of a reservoir cylinder body and a connection tube, which comprises a cylinder body and an air-out connection tube. The lower end of the air-out connection tube is arranged in the lower port of the cylinder body, and the lower port of the cylinder body is a rotary extrusion necking. At least two interior locating points are arranged on the rotary extrusion necking, and the lower port of the air-out connection tube adopts a spin over which is matched with the interior convex locating points in an interference or a transition way. The air-out connection tube and the cylinder of the coordination structure adopt the tight assembled structures, but after the tight assembly, the matching parts can be ensured to have clearance and the solder infiltration quality can be ensured. The flame weld can be adopted with an air-out bent tube, and adopting the structure can eliminate a welding procedure of furnace integrated welding. A dual-channel flame weld is adopted to carry out the welding directly, and welding material only adopts strong solder. Not only the cost of solder is low, the turnaround speed is accelerated, but the fabrication technology is simple and the manufacturing burden is greatly reduced.

Description

Reservoir cylindrical shell and adapter fit structure

[technical field]

The utility model relates to the cooler compressor reservoir, relates in particular to a kind of novel fit structure of outgoing gas connection tube and cylindrical shell in the reservoir.

[background technology]

In the prior art, cooler compressor is consulted Fig. 1 with the structure of reservoir, is made up of air inlet pipe 1, the bend pipe 2 of giving vent to anger, outgoing gas connection tube 3, cylindrical shell 4, filter screen 5.In this structure, it is high to consider between outgoing gas connection tube 3 and the cylindrical shell 4 that axiality requires, so, in the prior art these two accessories are all adopted as shown in Figure 1 structure, adopt the mode of the tight dress of complete closed to assemble, adopt following two kinds of welding manners to weld again:

1, after each spare and accessory parts assembling of reservoir, welding manner adopts " one weldering in the stove ", and welding material all adopts " silver solder " or " phosphor bronze ".

2, after cylindrical shell 4, filter screen 5 and outgoing gas connection tube 3 assemblings, adopt " red copper " scolder to carry out " one weldering in the stove " earlier, adopt " brass " scolder and its air inlet pipe 1, the bend pipe 2 of giving vent to anger to carry out the welding of twice flame again.

More than two kinds of welding procedures scolder cost height not only, and processing technology complexity, particularly the manufacturing cost of " one weldering in the stove " is higher much than alternate manner.

[summary of the invention]

The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of reservoir cylindrical shell and takes over fit structure, can either effectively guarantee the axiality requirement of cylindrical shell and adapter, can simplify adding technology again, increases work efficiency, and reduces cost.

For achieving the above object, the utility model proposes a kind of reservoir cylindrical shell and take over fit structure, comprise cylindrical shell and outgoing gas connection tube, the bottom of described outgoing gas connection tube is arranged in the lower port of cylindrical shell, the lower port of described cylindrical shell is the spinning reducing, be equipped with at least two convex anchor points in the spinning reducing, enlarging, enlarging and interference of convex anchor point or interference fits are adopted in the bottom of described outgoing gas connection tube.

As preferably, described at least two convex anchor points are all on same periphery.

As preferably, the quantity of described convex anchor point is 2 or 3 or 4.

As preferably, described at least two convex anchor points are on different peripheries.

As preferably, the quantity of described convex anchor point is 8, divides to be on 2 different peripheries, is symmetrically distributed with 4 convex anchor points on each periphery.

The beneficial effects of the utility model: the same structure that adopts tight dress of outgoing gas connection tube and cylindrical shell in the utility model, but can guarantee that its matching part has the gap behind the tight dress, guarantee scolder infiltration quality, can adopt the flame welding with the bend pipe of giving vent to anger.Adopt this structure can cancel the welding procedure of " one weldering in the stove ", directly adopt the mode of twice flame welding to weld, welding material is as long as adopt a kind of " strong solder ", not only the scolder cost is low, turnaround speed is accelerated, and manufacturing process is simple, and manufacturing expense reduces greatly.

Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.

[specific embodiment]

Embodiment one:

Consult Fig. 3, reservoir cylindrical shell and adapter fit structure, comprise cylindrical shell 4 and outgoing gas connection tube 3, the bottom of described outgoing gas connection tube 3 is arranged in the lower port of cylindrical shell 4, the lower port of described cylindrical shell 4 is the spinning reducing, be equipped with at least two convex anchor points 6 in the spinning reducing, enlarging, enlarging and 6 interference of convex anchor point or interference fits are adopted in the bottom of described outgoing gas connection tube 3.Described at least two convex anchor points 6 are all on same periphery.The quantity of described convex anchor point 6 can be 2 or 3 or 4, and the convex anchor point 6 on the general same periphery is symmetrically distributed on periphery.As another kind of mode, also can on same periphery, stamp the interior male structure of whole annular.

Whole process is:

1. cylindrical shell 4 forms through the spinning reducing, and it cooperates reservation certain clearance amount the outside dimension after the internal diameter size after the reducing and outgoing gas connection tube 3 enlargings;

2. get ready in spinning reducing place of cylindrical shell 4, get convex anchor point 6, get ready and can form on equipment such as hydraulic press or punch press, anchor point is to convex, makes its outgoing gas connection tube 3 enlarging positions just carry out the mode of close-fitting with the position of the convex anchor point 6 of cylindrical shell 4.The quantity of convex anchor point 6 can adopt two, three, four or more a plurality of.

3. outgoing gas connection tube 3 adopts special tooling with cylindrical shell 4 assemblings, guarantees to assemble back size and axiality.

4. after outgoing gas connection tube 3 assembles with cylindrical shell 4, adopt the flame welding, the bend pipe 2 of giving vent to anger, 4 flame welding of outgoing gas connection tube 3 and cylindrical shell; Cylindrical shell 4 other ends and air inlet pipe 1 are carried out a flame welding again and are finished whole reservoir.

By above design processing mode, as long as adopt the welding of twice flame just can finish, and guaranteed the infiltration quality of cooperation and scolder equally, needn't pass through the technology of furnace brazing again, thereby manufacturing cost reduces greatly.

Embodiment two:

Consult Fig. 4, in the present embodiment, convex anchor point 6 is in respectively on 2 different peripheries, and the convex anchor point 6 on each periphery is symmetrically distributed.As adopting 8 convex anchor points 6 altogether, 4 the convex anchor points 6 that then distribute on each periphery are made a call to a convex anchor point 6 for each 90 °.

The foregoing description is to explanation of the present utility model, is not to qualification of the present utility model, any structure after the utility model simple transformation is all belonged to protection domain of the present utility model.
