Problems solved by technology
On the one hand, non-destructive testing is time-consuming and labor-intensive, requiring special equipment and testing personnel; on the other hand, resistance spot welding has lower requirements for operators and better welding consistency. Determine welding parameters
[0004] However, the existing resistance spot welding equipment cannot conveniently realize the automatic alignment of the welding test plate, cannot guarantee the length of the lap edge of the test plate, and does not have functions such as auxiliary welding tongs positioning
The single-side spot welding operation of the existing resistance spot welding tool is complicated, and the test parameters after welding are difficult to meet the needs of actual work

The invention provides a resistance spot welding tool, comprising: a tool body, one end of the tool body is used to connect with one end of the static electrode of the welding tongs, a moving electrode of the welding tongs is arranged above the other end of the static electrode of the welding tongs, and the static electrode of the welding tongs Cooperate with the moving electrode of the welding tongs to define the installation space; the supporting plate is set in the installation space and connected to the other end of the static electrode of the welding tongs to be supported by the static electrode of the welding tongs, and the sample to be welded is set on the supporting surface And at least a part of it stops against the raised part; the pressing block is arranged on the sample to be welded to compress the sample to be welded and the supporting plate in the installation space; the connecting piece is connected to the supporting plate and the sample to be welded respectively The parts are connected with the briquetting block to fix the supporting plate, the sample to be welded and the briquetting block on the static electrode of the welding tongs. The resistance spot welding tool according to the embodiment of the present invention can ensure the alignment between the sample to be welded, the position of the welding spot and the moving electrode of the welding tongs, and is convenient for the subsequent tensile test.
Description
technical field [0001] The invention relates to the technical field of mechanical welding, and more specifically, relates to a resistance spot welding tool. Background technique [0002] Because resistance spot welding does not require filler metals such as welding wires and electrodes, and welding materials such as argon gas and CO2 gas, and the metallurgical process is simple, the operation is flexible and convenient, the welding cost is low and the productivity is high, it is currently the most important welding method for body sheet welding. [0003] The quality of welding directly determines the connection strength of the car body, which has an important impact on the safety of the car body. On the one hand, non-destructive testing is time-consuming and labor-intensive, requiring special equipment and testing personnel; on the other hand, resistance spot welding has lower requirements for operators and better welding consistency. Therefore, destructive tests of welding ...
