[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a spring welding device, comprising a fixed bracket, an electric lifting rod is suspended above the fixed bracket, a welding module is installed at the bottom end of the electric lifting rod, a guide rail is provided below the welding module, two sliders are slidably connected to the guide rail, two sliders are provided with two clamping parts arranged opposite to each other, the guide rail is installed on the second turntable, the second transmission rod is connected below the second turntable, and the second transmission rod is connected to the output end of the second forward and reverse motor at one end away from the second turntable.

[0007] Optionally, the clamping part includes a slide groove, a push rod, a clamping plate, a cam, a cam groove, a first turntable, a first transmission rod and a first forward and reverse motor. The outer shell of the clamping part is provided with three slide grooves, and each of the three slide grooves is slidably connected to a push rod. A clamping plate is provided at one end of the push rod away from the slide groove, and a cam is connected to one end of the push rod away from the clamping plate. The three cams are respectively slidably connected to corresponding cam grooves. The three cam grooves are arranged on the first turntable. A first transmission rod is provided on the first turntable. An end of the first transmission rod away from the push rod is connected to the output end of the first forward and reverse motor, and the first forward and reverse motor is fixed inside the clamping part.

[0011] Optionally, the fixed bracket is provided with a controller.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, two clamping parts arranged opposite to each other can respectively stabilize two different springs or metal structures. The two clamping parts are driven by a slider and slide freely on the guide rail. According to the length of the clamped object, the position of the clamped object can be flexibly adjusted, and the position where the two need to be welded is adjusted to just below the welding module.

The first turntable is specially provided with three cam grooves divided into three parts. The inside of the cam groove is smoothly connected to the cam, and the cam is connected to three clamping plates outside through a push rod. Therefore, when the first forward and reverse motor drives the first transmission rod to rotate, the cam will slide in the cam groove, thereby driving the three clamping plates to approach or move away from each other, so as to clamp and fix the object quickly and accurately.

[0025] In this embodiment, the two clamping parts 4 arranged opposite to each other can respectively stabilize two different springs or metal structures. The two clamping parts 4 are driven by the slider 9 and slide freely on the guide rail 8. According to the length of the clamped object, the position of the clamped object can be flexibly adjusted, and the position where the two need to be welded is adjusted to be directly below the welding module 3. Through the drive of the second forward and reverse motor 19, the second transmission rod 16 rotates and drives the second turntable 15 to rotate, so that the angles of the two clamping parts 4 can be accurately adjusted, and the structure to be welded can be further flexibly positioned and fixed. At the same time, the electric lifting rod 2 ensures that the welding module 3 can be stably lifted and lowered, and the two structures can be accurately welded, which significantly improves the welding efficiency. In addition, the guide rail 8 adopts an iron structure, and magnetic stones are arranged on the guide rail 8 on both sides of the slider 9, so that the slider 9 can be quickly fixed, avoiding the shaking problem that may occur during the welding process.

[0026] The clamping part 4 includes a slide groove 5, a push rod 6, a clamping plate 7, a cam 10, a cam groove 11, a first turntable 12, a first transmission rod 13 and a first forward and reverse motor 14. The outer shell of the clamping part 4 is provided with three slide grooves 5, and each of the three slide grooves 5 is slidably connected to a push rod 6.

The inside of the cam groove 11 is smoothly connected to the cam 10, and the cam 10 is connected to the three clamping plates 7 on the outside through the push rod 6. Therefore, when the first forward and reverse motor 14 drives the first transmission rod 13 to rotate, the cam 10 will slide in the cam groove 11, thereby driving the three clamping plates 7 to approach or move away from each other, so as to clamp and fix the object quickly and accurately, ensuring a stable and efficient clamping process.
