Description

Technical Field

[0001] The present application relates to the technical field of welding equipment, and in particular to a welding jig and welding equipment. Background Art

[0002] With the increasing use of new energy vehicles, flat wire motors are a very important component in new energy vehicles and play a vital role in the performance of the entire vehicle. The welding of flat copper wire is an important link in the production and manufacturing of flat wire motors. The quality of welding determines the quality of the entire flat wire motor. Usually, the welding process parameters need to be tested before formal welding. During welding, whether the material can be aligned during clamping has a great influence on the welding result. However, due to the influence of harmful factors such as high temperature, smoke, radiation, etc. of laser welding, it is impossible to directly fix the welding workpiece by hand during the welding process. Therefore, it is usually necessary to use a clamp to fix the flat wire during the welding test.

[0003] In the flat copper wire welding, there is a type of X-Pin type winding, which belongs to the lap welding of the bevel. Usually before welding, the welding product needs to be tested and welded to determine its welding parameters. During the welding test, the relatively simple welding fixture is usually used to fix and position the product manually. However, simple general fixtures cannot clamp flat copper wire materials quickly and efficiently, and cannot ensure the flatness of the bevel and the tight fit between the copper wires, which will lead to low welding efficiency. At the same time, the poor alignment of the bevel and the loose fit between the copper wires will lead to poor welding results, which will have a great impact on the laser welding test results, that is, it will lead to low test efficiency, inaccurate test results and other problems, which seriously affect normal production.

[0055] like Figure 1 As shown, an embodiment of the present application provides a welding fixture 100. The welding fixture 100 includes a fixing assembly 110, a clamping assembly 120 and an adjusting assembly 130.

[0056] The fixing assembly 110 has a receiving groove 113 , and the clamping assembly 120 is disposed in the receiving groove 113 .

[0057] In this embodiment, the clamping assembly 120 includes a first clamping member 121 and a second clamping member 122, which are used to clamp the first flat copper wire 101 and the second flat copper wire 102 together and align the chamfered surfaces of the first flat copper wire 101 and the second flat copper wire 102.

[0058] Specifically, by placing the welding jig 100 of this embodiment on a flat welding workbench, and then by tilting the first flat copper wire 101 and the second flat copper wire 102 between the first clamping piece 121 and the second clamping piece 122, and placing the end of the first flat copper wire 101 with the beveled surface and the end of the second flat copper wire 102 with the beveled surface against the surface of the welding workbench, and by placing the surface of the welding jig 100 as a reference for aligning the beveled surfaces of the flat copper wires, the problem of difficulty in aligning the beveled surfaces of the flat copper wires due to manual clamping and universal clamping during welding proofing of the flat copper wires is effectively solved, the efficiency of aligning the beveled surfaces of the flat copper wires is improved, and the welding efficiency and welding quality are improved.

[0059] Among them, the fixing assembly 110 includes a clamping screw 1122, one end of the clamping screw 1122 is located in the accommodating groove 113, the clamping screw 1122 is located on the side of the second clamping member 122 away from the first clamping member 121, and one end of the clamping screw 1122 close to the second clamping member 122 abuts against the second clamping member 122. The clamping screw 1122 is used to push the second clamping member 122 and the first clamping member 121 to jointly clamp the first flat copper wire 101 and the second flat copper wire 102.

[0060] The adjusting assembly 130 is respectively disposed on one side of the first clamping member 121 and the second clamping member 122 , and the adjusting assembly 130 is used to adjust the relative position of the first clamping member 121 and the second clamping member 122 .

[0061] In the related art, usually the simpler welding fixture is manually fixed and positioned. However, the simple universal fixture cannot quickly and efficiently clamp the flat copper wire material, and cannot ensure the flatness of the bevel and the tight fit between the copper wires, which will lead to low welding efficiency. At the same time, the poor alignment of the bevel and the loose fit between the copper wires will lead to poor welding effect, which has a great impact on the laser welding test results, that is, it leads to low test efficiency, inaccurate test results and other problems, which seriously affects normal production.

[0062] In this embodiment, the welding jig 100 includes a fixing component 110, a clamping component 120 and an adjusting component 130. By placing the welding jig 100 of this embodiment on a flat welding workbench, and then by tilting the first flat copper wire 101 and the second flat copper wire 102 between the first clamping piece 121 and the second clamping piece 122, and making the beveled surface of the first flat copper wire 101 and the beveled surface of the second flat copper wire 102 fit with the table of the welding workbench, and by using the table as a reference for the alignment of the beveled surfaces of the flat copper wires, the problem of the difficulty in aligning the beveled surfaces of the flat copper wires due to manual and universal clamping during welding proofing of the beveled surfaces of the flat copper wires is effectively solved, the efficiency of aligning the beveled surfaces of the flat copper wires is improved, and the welding efficiency and welding quality are improved. At the same time, in this embodiment, the clamping screw 1122 is used to tighten the second clamping piece 122 so that the ends of the two flat copper wires with the beveled surfaces are completely fitted, reducing the influence of clamping on the welding effect and further improving the welding quality.
