Description

Brazing tool structure for spacer of oil cooler

Technical Field

The utility model relates to a technical field is made to the automobile-used oil transfer cooler, in particular to oil cooler spacer frock structure of brazing.

Background

In the heat exchanger plant of the automotive industry, an oil cooler is a very common plant.

In the existing oil cooler manufacturing, the outer spacers of the oil cooler header are connected in a brazing mode.

However, because the common brazing temperature window of the coating material of the separator and the coating materials of other parts is small, in actual operation, the coating material of the separator is easily lost at high brazing temperature, so that a gap is formed at the joint of the inner side of the separator and other parts, the leakage of products is caused, and unqualified products are produced.

Therefore, how to prevent the oil cooler header and the corresponding spacer from generating a gap in the brazing process and leakage becomes a technical problem which needs to be solved urgently by the technical personnel in the field.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned defect of prior art, the utility model provides an oil cooler spacer frock structure of brazing, the purpose of realization is solved oil cooler header and corresponding spacer and produces the breach at the in-process of brazing, stops the production of unqualified product, improves production efficiency.

In order to achieve the purpose, the utility model discloses an oil cooler spacer frock structure of brazing, collect the pipe including the oil cooler, and with the oil cooler collects the pipe and passes through the fixed spacer of the mode of brazing.

The spacers are symmetrically arranged on two sides of the oil cooler header;

the inner side surface of each spacer is fixedly connected with the oil cooler header pipe in a brazing mode;

the outer side surfaces of the two spacers are respectively provided with a pressing block;

each pressing block presses the corresponding spacer towards the inner side direction of the spacer.

Preferably, each of the pressing blocks obtains a force for pressing the corresponding spacer by arranging an elastic body.

More preferably, the elastic body is a tension spring.

More preferably, two ends of the tension spring are respectively connected with the two pressing blocks.

Preferably, the two pressing blocks are respectively connected with the two clamping parts of the spring clamp clamping opening.

The utility model has the advantages that:

the utility model discloses an use and to solve oil cooler header and corresponding spacer and produce the breach at the in-process of brazing, stop the production of unqualified product, improve production efficiency.

The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.

Detailed Description

Examples

As shown in FIG. 1, the brazing tooling structure for the oil cooler spacer comprises an oil cooler header 1 and a spacer 2 fixed with the oil cooler header 1 in a brazing mode.

Wherein, the spacers 2 are symmetrically arranged at two sides of the oil cooler header 1;

the inner side surface of each spacer 2 is fixedly connected with the oil cooler header 1 in a brazing mode;

the outer side surfaces of the two spacers 2 are respectively provided with a pressing block 3;

each pressing piece 3 presses the corresponding spacer 2 toward the inner side thereof.

The principle of the utility model is as follows:

by applying a force to the spacer 2 to push the spacer 2 to the welding point, the spacer 2 is enabled to obtain a tendency of moving to the welding point during brazing, when the coating material of the spacer 2 is lost at high brazing temperature, the welding point of the spacer 2 is pushed to move, the lost coating material is compensated, and the defect that a gap is generated and leakage occurs after welding is eliminated.

In some embodiments, each pressure piece 3 is provided with an elastic body to obtain a force to press the corresponding spacer 2.

In some embodiments, the elastomer is a tension spring 4.

In some embodiments, two ends of the tension spring 4 are respectively connected with the two pressing blocks 3.

In some embodiments, two pressing pieces 3 are respectively connected with two clamping parts of the spring clamping opening.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
