[0016] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0017] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0018] Embodiment 1

[0019] like Figure 1As shown, a specific embodiment of the utility model provides a copper gasket 500 welding positioning and clamping tooling, which has a positioning and clamping function and can implement rapid welding, and specifically includes a plurality of positioning pins 100 arranged at intervals, an elastic member 200 is sleeved on the positioning pin 100, and a detachable limiting plate 300 is horizontally inserted at the upper end of the positioning pin 100. When the lower end of the positioning pin 100 is inserted into the copper plate 400 and the copper gasket 500 arranged vertically, the elastic member 200 is compressed so that its lower end abuts against the copper plate 400 and its upper end abuts against the limiting plate 300.

[0020] like Figure 1 As shown, through the above-mentioned arrangement, the positioning and clamping tooling in this embodiment adopts a split structure, and the positioning pin 100 and the elastic member 200 and the limiting plate 300 are detachable and separable. When some parts are damaged in production applications, the corresponding parts can be replaced in time, which can effectively reduce the overall time consumption. The positioning pin 100 can be positioned after insertion, and after the positioning is completed, it is clamped and positioned by the spring structure. The clamping tooling is easy to assemble and use, and through the convenient and fast disassembly and assembly method, the assembly line operation in the reflow soldering process can be realized, thereby improving production capacity and production efficiency.

[0021] like Figure 1 As shown, in order to improve the stability of the limiting piece 300 inserted into the upper end of the positioning pin 100, the upper end of the positioning pin 100 is provided with a positioning ring groove arranged at intervals in the upper and lower parts of the outer periphery of the limiting piece 300, and the limiting piece 300 is arranged in a U shape, and the opening of the limiting piece 300 can be inserted into the positioning ring groove. In this way, after the limiting piece 300 is inserted into the positioning ring groove, the limiting piece 300 forms a limit so that the elastic member 200 can stably apply a clamping force to the copper plate 400, and the limiting piece 300 can be quickly removed to release the clamping force of the elastic member 200.

[0022] In actual application, the positioning pin 100 is made of Teflon material; since Teflon material does not adhere to the solder used to weld the copper sheet, the positioning pin 100 is more convenient to disassemble and can be reused; the limit plate 300 is cut and formed from stainless steel; in addition, the elastic member 200 is a wire spring, which can accumulate elastic force when compressed to apply a stable clamping force to the copper plate 400 to ensure the welding effect. In production, when the lower end of the positioning pin 100 is inserted into the copper plate 400 and the copper gasket 500 arranged up and down, the positioning pin 100 forms a clearance fit with the copper plate 400 and the copper gasket 500. In this embodiment, the positioning pins 100 are arranged in pairs, so as to implement positioning on both ends of the copper plate 400.

[0023] Embodiment 2

[0024] This embodiment uses the positioning and clamping tool in the first embodiment to propose a process for welding, positioning and clamping a copper gasket 500, including the following steps:

[0025] Step 1. Positioning: stack the unsoldered copper plate 400 and copper gasket 500 up and down, and use the lower end of the positioning pin 100 to insert the copper plate 400 and the copper gasket 500 from top to bottom. After the positioning pin 100 is inserted, it can be positioned so that the positioning pin 100 and the copper plate 400 and the copper gasket 500 have a clearance fit, and the copper plate 400 and the copper gasket 500 cannot be relatively offset, thereby completing the quick positioning operation.

[0026] Step 2. Clamping; put the elastic member 200 on the positioning pin 100 so that the lower end of the elastic member 200 abuts against the copper plate 400, and insert the limiting plate 300 horizontally into the positioning ring groove so that the upper end of the elastic member 200 abuts against the limiting plate 300; that is, after the positioning is completed, the spring structure is used to clamp and position, and the clamping tooling is easy to assemble and use. Through convenient and fast disassembly and assembly, assembly line operation during reflow soldering can be achieved.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
