[0019] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0020] See attached Figure 1-5 A wire rack welding positioning tool comprises a positioning bracket 1 and a welding tool, wherein the positioning bracket 1 is provided with a plurality of positioning grooves, and the plurality of positioning grooves cooperate with the iron wires forming the wire rack 2 and the connecting member 3 to fix the positions of the wire rack 2 and the connecting member 3; the welding tool comprises an upper electrode 8 and a lower electrode 9 which form a connected circuit after contact, and corresponding positions of the upper electrode 8 and the lower electrode 9 are formed with a through groove 10 for the positioning bracket 1 to pass through.

[0021] Based on the above technical solution, it should be noted that after the upper electrode 8 and the lower electrode 9 simultaneously contact the wire rack 1, the circuit is connected for welding due to the electrical conductivity of the wire. The upper electrode and the lower electrode in the present invention are the motor structure of the riveting welding machine, and the related circuits, lifting structures, and driving mechanisms all adopt the riveting welding machine structure commonly used in the art. The above content is not suitable for the scope of improvement and protection of this application, and this application does not limit other related structures of the riveting welding machine.

[0022] Furthermore, the positioning bracket 1 is a tic-tac-toe structure composed of four support plates, the four support plates include two parallel long plates and two parallel short plates, the four support plates are all straight plates, adjacent long plates and short plates are perpendicular to each other, and a number of positioning grooves are arranged on the upper surfaces of the four support plates.

[0023] Furthermore, the plurality of positioning grooves include a wire rack positioning groove 4 and a connector positioning groove 5. Among the two parallel long plates, one long plate has two connector positioning grooves 5 in the middle for assembling two parallel sides of the connector 3, and the other long plate has an arc groove 6 in the middle for accommodating the bent end of the connector 3.

[0024] Furthermore, a support platform 7 for supporting the bent end is provided inside the arc groove 6, and the support platform 7 is connected to the inner surface of the middle part of the long plate. The upper surface of the support platform 7 is inclined to match the bent end of the connector 3. In the above description, the opposite side of the two parallel plates is the inner side.

[0025] Furthermore, the four support plates are welded and connected, and the support platform 7 is welded on the positioning bracket 1 .

[0026] Furthermore, the upper electrode 8 is installed in the upper electrode holder, the lower electrode 9 is installed in the lower electrode holder, and the upper electrode holder and the lower electrode holder are connected to the internal circuit of the riveting welding machine.

[0027] Based on the above technical solution, the part of the upper electrode 8 that is far from the lower electrode 9 and installed in the upper electrode holder is a connected structure, which is convenient for the overall current path of the upper electrode 8. The upper electrode 8 is formed with a through groove 10 that cuts off the upper electrode 8 along the thickness direction on the side close to the lower electrode 9, so that the positioning bracket 1 can slide through. The part of the lower electrode 9 that is far from the upper electrode 8 and is located in the processing platform 11 and installed in the lower electrode holder is a connected structure, which is convenient for the overall current path of the lower electrode 9. The part of the lower electrode 9 that is close to the upper electrode 8 and exposed to the processing platform 11 is formed with a through groove 10 that cuts off the lower electrode 9 along the thickness direction, so that the positioning bracket 1 can slide through.

[0028] Furthermore, when the positioning bracket slides into the through groove of the lower electrode, the lower surface of the positioning groove in the positioning bracket is flush with the upper surface of the lower electrode, so that the lower electrode is contacted and supported by the wire frame in the positioning bracket.

[0029] Furthermore, a wire rack welding positioning tool also includes a processing platform 11, the lower electrode 9 is embedded in the processing platform 11, the lower bottom surface of the through groove 10 of the lower electrode 9 is flush with the upper surface of the processing platform 11, and the positioning bracket 1 slides on the processing platform 11.

[0030] Based on the above technical solution, the welding position of the wire rack 2 and the connector 3 needs to be between the upper electrode 8 and the lower electrode 9, but the wire rack 2 and the connector 3 are replaced between the upper electrode 8 and the lower electrode 9. Due to limited space, it is inconvenient to operate and it is easy to bump the electrodes. Therefore, the lower electrode 9 is embedded in the processing platform 11, so that the lower bottom surface of the through groove 10 of the lower electrode 9 is flush with the upper surface of the processing platform 11. There is no slideway on the surface of the processing platform 11, which is convenient for directly lifting or lowering the positioning bracket 1. The positioning bracket 1 can slide directly on the upper surface of the processing platform 11 and the through groove 10 of the lower electrode 9. When welding, the positioning bracket 1 equipped with the wire rack 2 and the connector 3 is slid along the through groove 10 of the lower electrode 9, so that the connector 3 is located between the upper electrode 8 and the lower electrode 9, the wire rack 2 contacts the upper surface of the lower electrode 9, and the upper electrode 8 is pressed down. The circuits between the upper electrode 8, the connector 3, the wire rack 2, and the lower electrode 9 are connected, and welding is performed. After welding is completed, the upper electrode 8 is lifted, the circuit is disconnected, and the positioning bracket 1 is slid along the through groove 10 of the lower electrode 9 to make the connecting part 3 withdraw from the welding position. The positioning bracket 1 can also be directly lifted to separate the positioning bracket 1 from the lower electrode 9, so that the connecting part 3 withdraws from the welding position, the welded product is removed, and a new wire rack 2 and connecting part 3 are re-installed in the positioning bracket 1, and the positioning bracket 1 is slid so that the connecting part enters the welding position between the upper electrode 8 and the lower electrode 9, and the above process is repeated.

[0031] according to Figure 1-Figure 4In the direction shown in the figure, the part where the wire rack 2 cooperates with the positioning bracket 1 is one side of the installation connector 3, including three longitudinal wires and four transverse wires. The four transverse wires are divided into two groups, each with two wires, which are respectively located on both sides of the three longitudinal wires. The connector is located in the middle of the three longitudinal wires. The parallel wires on both sides of the connector are arranged and welded with the three longitudinal wires in a cross-shaped manner. The bent end of the connector 3 clamps the outermost longitudinal wire. Correspondingly, the two short plates of the positioning bracket 1 are arranged horizontally, and three wire rack positioning grooves 4 are correspondingly arranged on the two short plates for assembling and positioning the three longitudinal wires. The two long plates are arranged longitudinally, the first long plate is connected between the first and second wire rack positioning grooves of the two short plates, a wire rack positioning groove 4 is arranged at each end of the first long plate, used to support and position the two inner transverse wires among the four transverse wires, two connector positioning grooves 5 are arranged in the middle of the first long plate, used to support and position the parallel wires on both sides of the connector 3, the second long plate is connected behind the third wire rack positioning groove of the two short plates, and an arc groove 6 is arranged in the middle of the second long plate, used to accommodate the bent end of the connector 3. The through grooves of the upper electrode and the lower electrode are for the first long plate to slide through, and when the first long plate of the positioning bracket 1 slides into the through groove 10 of the lower electrode 9, the two long plates are located outside the upper and lower electrodes 8 and 9, and the side surface of the lower electrode close to the second long plate is concave to form a cavity, so as to facilitate the entry of the bent end of the connector and the support platform 7 of the positioning bracket.

[0032] It should be noted that Figure 1-Figure 5 The wire rack and positioning bracket are used as an example of a structural style. If the arrangement of the wires of the wire rack to be processed is changed or the fixed position of the connecting piece is changed, the positioning bracket and the positioning groove position need to be adaptively changed. At the same time, the slot position and number of the upper and lower electrodes may also need to be changed. The deformed positioning bracket structure and its adapted welding electrode also fall within the protection scope of the present utility model.
