Technical Field
[0001] The invention relates to the technical field of welding positioner electrode devices, in particular to a welding positioner electrode device and method. Background Art
[0002] The welding positioner is a commonly used welding auxiliary equipment in welding operations. During actual use, poor electrode contact often occurs, resulting in poor welding. For general welding equipment, the negative pole of the welding power supply will be directly connected to the workpiece to be welded, but there are multiple moving axes in the welding positioner, and the motor cannot be directly connected to the workpiece to be welded. The current solution is to install the negative pole line of the welding machine at the position of the rotating disk of the welding positioner. Friction conducts electricity between the rotating disk and the electrode. However, general welding positioners have the problem of decreased conductivity after electrode wear during production, and the problem of electrode leakage causing the encoder of the external axis motor of the welding positioner to burn out.
[0003] Based on this, a welding positioner electrode device is now provided, which can eliminate the disadvantages of the existing device. Summary of the invention
[0004] The object of the present invention is to provide an electrode device for a welding positioner to solve the problems of electrode wear leading to decreased electrode conductivity and electrode leakage in the background art.
[0005] To achieve the above object, the present invention provides the following technical solutions:

[0007] On the basis of the above technical solution, the present invention also provides the following optional technical solution:
[0008] In an optional solution: the wiring module includes a conductive seat arranged on a conductive rod, the conductive seat is provided with a wiring terminal connected to the wire, the wiring terminal is penetrated by a fixing bolt, and the fixing bolt penetrates the conductive seat and is threadedly connected to the conductive rod.
[0009] In an optional scheme: the contact pressure maintaining structure includes a reset spring sleeved on the outside of the conductive rod, the outer diameter of the reset spring is smaller than the inner diameter of the plug-in sleeve, an annular spring pressure plate is slidably provided in the plug-in sleeve, the spring pressure plate is sleeved on the outside of the conductive rod, the plug-in sleeve is provided with a guide component for guiding the spring pressure plate, and a pressure adjustment component for adjusting the compression amount of the reset spring is provided on the outside of the plug-in sleeve.

[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. The present invention supports the conductive rod by a reset spring. When the conductive rod is worn, the reset spring is extended so that the contact pressure between the conductive rod and the rotating disk of the welding positioner does not disappear directly, thereby ensuring the conductive performance between the conductive rod and the rotating disk.
[0016] 2. The present invention provides an insulating plate to provide an insulating isolation effect on the conductive rod, thereby preventing current leakage on the conductive rod from causing damage to other equipment.
[0017] 3. The present invention drives the spring pressure piece to move in the plug-in sleeve through the circular nut, thereby changing the compression amount of the reset spring, which is convenient for adjusting the contact pressure between the conductive rod and the turntable during installation. At the same time, after the conductive rod is excessively worn, the supporting force provided by the reset spring is reduced. By rotating the circular nut, the spring pressure piece is driven to compress the reset spring, so that the reset spring provides sufficient supporting force for the conductive rod again, thereby eliminating the need to replace the conductive rod, extending the replacement cycle of the conductive rod, improving production efficiency, and reducing production costs.

[0025] In this embodiment, the insulating plate 107 acts as an insulator to prevent the current on the conductive rod 103 from leaking. The wiring module firmly connects the wires to the conductive rod 103 to ensure the normal operation of the conductive rod 103. After the conductive rod 103 is worn, the contact pressure maintaining structure reduces the change in contact pressure between the conductive rod 103 and the rotating disk of the welding positioner, thereby ensuring the conductive performance between the conductive rod 103 and the rotating disk.
[0026] In one embodiment, Figure 2 As shown, the wiring module includes a conductive seat 104 arranged on a conductive rod 103, and a wiring terminal 105 connected to the electric wire is provided on the conductive seat 104.
