DETAILED DESCRIPTION

[0018] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0019] The first embodiment of the present application is:

[0020] See alsoFigures 1 to 4 , wherein Figure 1 is a schematic diagram of the overall structure of the conductive mechanism of a two-station spot welding fixture, Figure 2 is a schematic diagram of the structure of the conductive device, Figure 3 is the overall left view of the conductive mechanism of the two-station spot welding fixture, Figure 4 is a schematic diagram of the structure of the auxiliary component. The present utility model provides a conductive mechanism for a two-station spot welding fixture: including a fixture lower base 101, a lower electrode 102, an upper electrode 103 and a conductive device. The conductive device includes a conductive block 104, an insulating support block 105, an adjustment component and an auxiliary component. The adjustment component includes a slide rail 106 and a reversing cylinder 107. The auxiliary component includes an insulating block 108 and a flexible connecting copper strip 109. A first threaded hole 110 is provided on the flexible connecting copper strip 109. Corresponding holes 111 are provided on both the conductive block 104 and the fixture lower base 101. Through the foregoing solution, it is solved that when the conductive mechanism works, the contact surface of the fixture lower base 101 through which the discharge current passes is easily ablated by the large current, resulting in an uneven contact surface (large change in discharge current), the welding quality of the workpiece cannot be guaranteed, and the service life of the fixture is shortened. It can be understood that the foregoing solution can be used to prevent the large current from directly passing through the non-working surface when the conductive mechanism works, so that the conductive mechanism works stably during use, and the welding quality is guaranteed. It can also be used to facilitate the installation and disassembly of the flexible connecting copper strip 109, so as to facilitate its replacement.

[0021] For this specific embodiment, the lower electrode 102 is located above the fixture lower base 101, the upper electrode 103 is located above the lower electrode 102. The fixture lower base 101 is used for conducting electricity to the workpiece. The lower electrode 102 and the upper electrode 103 are sequentially arranged above the fixture lower base 101. When the conductive mechanism works, the discharge current passes through the upper electrode 103 to the workpiece to be spot welded, then to the lower electrode 102, and finally reaches the fixture lower base 101, thereby completing the conductive operation.

[0022] Among them, the conductive block 104 is arranged on the lower base 101 of the fixture. The insulating support block 105 is fixedly connected to the conductive block 104 and is located on one side of the conductive block 104. The adjusting assembly is arranged on the lower base 101 of the fixture. The conductive block 104 is connected to the adjusting assembly and moves on the lower base 101 of the fixture through the adjusting assembly. The auxiliary assembly is arranged on the lower base 101 of the fixture. The adjusting assembly is arranged on the upper surface of the lower base 101 of the fixture. The conductive block 104 is connected to the adjusting assembly. The conductive block 104 is used to transfer current from the lower electrode 102 to the lower base 101 of the fixture. The conductive block 104 can be horizontally moved and vertically adjusted on the lower base 101 of the fixture through the adjusting assembly, so as to facilitate the conduction of current for workpieces to be spot welded with different sizes. The insulating support block 105 is fixed on the lower base 101 of the fixture. The setting of the insulating support block 105 can prevent the lower base 101 of the fixture from being burned by large current and extend the service life of the lower base 101 of the fixture. The auxiliary assembly is arranged on the lower base 101 of the fixture. The setting of the auxiliary assembly can prevent the contact surface between the conductive block 104 and the lower base 101 of the fixture from being burned by large current when the current is too large, resulting in an uneven contact surface, thereby avoiding the problem that the welding quality of the workpiece cannot be guaranteed. During the use of this conductive mechanism, by setting the auxiliary assembly, after adjusting the position of the conductive block 104 according to the workpiece to be spot welded, the discharge current of the mechanism sequentially passes through the upper electrode 103, the workpiece to be spot welded, the lower electrode 102, the conductive block 104, the auxiliary assembly and the lower base 101 of the fixture, so that large current is prevented from directly passing through the non-working surface during the operation of the conductive mechanism, making the conductive mechanism work stably during use and ensuring the welding quality.

[0023] Secondly, the slide rail 106 is fixedly connected to the lower base 101 of the fixture and is slidably connected to the conductive block 104; the reversing cylinder 107 is fixedly connected to the lower base 101 of the fixture and is threadedly connected to the conductive block 104. The slide rail 106 is arranged on the upper surface of the lower base 101 of the fixture. The conductive block 104 moves on the slide rail 106 through a slider, so as to adjust the horizontal position of the conductive block 104. The reversing cylinder 107 is arranged on the upper surface of the lower base 101 of the fixture. The output end of the reversing cylinder 107 is connected to the conductive block 104. The output end of the reversing cylinder 107 is connected to the conductive block 104 in the form of a ball screw, so that when the reversing cylinder 107 is started, it can drive the conductive block 104 to move in the vertical direction, thereby facilitating the adjustment of the position of the conductive block 104 and making it convenient to conduct current for workpieces to be spot welded with different sizes.

[0024] Meanwhile, the insulating block 108 is detachably connected to the lower base 101 of the fixture and is located between the lower base 101 of the fixture and the conductive block 104. The insulating block 108 is disposed on the upper surface of the lower base 101 of the fixture, and the insulating block 108 is located on the lower surface of the conductive block 104. The arrangement of the insulating block 108 prevents current from directly passing through the conductive block 104 into the lower base 101 of the fixture during conduction, thereby protecting the lower base 101 of the fixture.

[0025] In addition, the flexible copper strip 109 is detachably connected to the conductive block 104 and is also detachably connected to the lower base 101 of the fixture; the first threaded hole 110 penetrates through the flexible copper strip 109; both the conductive block 104 and the lower base 101 of the fixture are provided with corresponding holes 111 adapted to the first threaded hole 110. The flexible copper strip 109 is formed by stacking multiple layers, the surface of the flexible copper strip 109 is arc-shaped, and the first threaded holes 110 are provided on both sides of the flexible copper strip 109. The corresponding hole 111 adapted to the first threaded hole 110 is provided at the left bottom of the conductive block 104, and the corresponding hole 111 is also provided on the left side of the lower base 101 of the fixture. After screwing the corresponding bolts into the first threaded hole 110 and the corresponding hole 111, it is convenient to install the flexible copper strip 109 between the lower base 101 of the fixture and the conductive block 104. The arc-shaped surface of the flexible copper strip 109 prevents large current from directly passing through the non-working surface during operation, making the mechanism more stable in use, improving the welding quality, and facilitating the installation and disassembly of the flexible copper strip 109, thereby facilitating its replacement.

[0026] When using the conductive mechanism of a two-workstation spot welding fixture according to this embodiment, during the use of this conductive mechanism, by setting the insulating block 108 and the flexible copper strip 109, after adjusting the position of the conductive block 104 according to the workpiece to be spot welded, the discharge current of the mechanism sequentially passes through the upper electrode 103, the workpiece to be spot welded, the lower electrode 102, the conductive block 104, the insulating block 108, the flexible copper strip 109, and the lower base 101 of the fixture. Thus, the conductive mechanism prevents large current from directly passing through the non-working surface during operation, making the conductive mechanism stable in use and ensuring the welding quality.
