[0030] Example 1

[0031] like Figure 1 As shown, the contact welding positioning device proposed in this utility model includes a base 1, a support column 2 fixed on the top of the base 1, a top plate 3 fixedly installed on the top of the support column 2, two cylinders 4 installed on the top plate 3, and a rectangular frame 5 fixed between the piston rods of the two cylinders 4; the position is adjusted by starting the cylinders 4 to drive the rectangular frame 5 to descend.

[0032] like Figures 1 to 5 As shown, two rectangular holes 6 are opened on both sides of the rectangular frame 5. Multiple position adjustment components are slidably installed between the two rectangular holes 6. The position adjustment components are slidably installed on the slide plate 7 between the two rectangular holes 6. The slide plate 7 moves horizontally. A slider 14 for installing the clamping component is slidably installed on one side of the slide plate 7. The slider 14 moves vertically, thereby realizing the position adjustment of the clamping component in the plane. The clamping position can be arbitrarily adjusted according to the alloy position on the switch base. It is suitable for processing various specifications of switch bases and improves the compatibility of the device.

[0033] like Figures 2 to 5 As shown, the slide plate 7 is provided with a limiting component 1 for fixing the position of the slide plate 7. The limiting component 1 includes a spring 8 fixed to the end of the slide plate 7. One end of the spring 8 is fixed with a handle 9. Both ends of the handle 9 are fixed with connecting rods 10. One end of the connecting rods 10 is fixed with a clamping plate 11 that abuts against the rectangular frame 5.

[0034] In addition, a groove 12 is provided on one side of the slide plate 7, and two track rods 13 are fixed in the groove 12. The slider 14 is slidably sleeved on the track rods 13, and the track rods 13 provide a moving track for the slider 14.

[0035] It is worth noting that the slider 14 is equipped with a limiting component two for fixing the position of the slider 14 on the slide plate 7. The limiting component two includes a bolt 15 threaded onto the slider 14. One end of the bolt 15 abuts against one of the track rods 13. By the bolt 15 abutting against the track rod 13, the position of the slider 14 can be fixed.

[0036] like Figure 6As shown, in this embodiment, a clamping assembly for clamping the contacts is installed on the position adjustment assembly. The clamping assembly includes a cylindrical tube 16 fixed to the bottom of the slider 14, a spring column 17 fixed inside the cylindrical tube 16, and a pressure rod 18 fixed to the bottom of the spring column 17. The bottom of the pressure rod 18 slides through the lower end face of the cylindrical tube 16 and is fixed with a pressure block 19. By starting the cylinder 4, the rectangular frame 5 is driven to descend, which in turn drives the clamping assembly to descend. The pressure block 19 presses against the top of the alloy contact. Then, the rectangular frame 5 continues to descend, the spring column 17 is compressed, and then the cylinder 4 stops, thus achieving clamping and fixing of the alloy contact, which is convenient to operate.

[0037] The working principle of this embodiment is as follows: The base 1 is used to place the switch base, and the switch base holds the alloy contacts. The spring 8 is always in a stretched state. By pulling the handle 9, the spring 8 is stretched again, the clamping plate 11 is disengaged from the rectangular frame 5, and the horizontal position of the slide plate 7 is moved until the horizontal position of the slide plate 7 is consistent with the horizontal position of the pressed alloy contacts. Then, the handle 9 is released, and under the restoring force of the spring 8, the clamping plate 11 abuts against the rectangular frame 5, thus fixing the position of the slide plate 7. Then, the bolt 15 is rotated to disengage from the track rod 13, and then the longitudinal position of the slider 14 is moved, thereby realizing the planar adjustment of the clamping assembly, so that the clamping assembly is located directly above the alloy contacts. The clamping position can be arbitrarily adjusted according to the alloy position on the switch base, which is suitable for processing various specifications of switch bases and improves the compatibility of the device. By starting the cylinder 4, the rectangular frame 5 is driven to descend, which drives the clamping assembly to descend. The pressure block 19 presses against the top of the alloy contacts, and then the rectangular frame 5 continues to descend, the spring column 17 is compressed, and then the cylinder 4 stops, realizing the clamping and fixing of the alloy contacts. The operation is convenient.

[0038] Example 2

[0039] like Figure 2 As shown, based on Embodiment 1, a guide rod is fixed inside the rectangular hole 6, and the slide plate 7 is slidably fitted onto the guide rod. The guide rod provides movement guidance for the slide plate 7, enabling the slide plate 7 to move stably.

[0040] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
