[0023] The utility model is further described below in conjunction with embodiments.

[0024] Embodiment 1:

[0025] See also Figure 2-Figure 5The clamping assembly 2 includes a support column 21 fixedly connected to the top of the fixed plate 42, a connecting plate 22 fixedly connected to the top of the support column 21, a rotating rod 23 movably passing through the connecting plate 22, a clamping frame 24 fixedly connected to one end of the rotating rod 23, a clamping plate 25 arranged on the inner side of the clamping frame 24, a first knob 27 fixedly connected to the other end of the rotating rod 23, and a limit block 26 movably connected to the outer surface of the rotating rod 23, the inner surface of the limit block 26 is provided with a positive thread channel 261, the outer surface of the rotating rod 23 is provided with a reverse thread channel 231, the positive thread channel 261 and the reverse thread channel 231 are arranged correspondingly, and the clamping plate 25 is used to clamp the workpiece. In the initial state, the limit block 26 is threadedly connected to the outer surface of the rotating rod 23, and the positive thread channel 261 is engaged with the reverse thread channel 231. At this time, the outer surface of the limit block 26 is against the outer surface of the connecting plate 22. The locking mechanism of the limit block 26 effectively fixes the rotating rod 23 inside the connecting plate 22. When the welding direction of the workpiece needs to be adjusted, the limit block 26 is rotated to make the reverse thread channel 231 away from the positive thread channel 261, and the initial locking state of the rotating rod 23 is released. By rotating the first knob 27, the rotating rod 23 is driven to rotate, thereby driving the clamping plate 25 to rotate, which is convenient for adjusting the welding direction of the workpiece.

[0026] A second groove 241 is provided on one side of the clamping frame 24, and a bidirectional threaded rod 5 is movably arranged inside the second groove 241. A second knob 51 is movably connected to one end of the clamping frame 24, and a slider is threadedly connected to the outer surface of the bidirectional threaded rod 5, and the slider is fixedly connected to the clamping plate 25. One end of the bidirectional threaded rod 5 is rotatably connected to the inner wall of the second groove 241, and the other end of the bidirectional threaded rod 5 passes through the second groove 241 and is fixedly connected to the second knob 51. The clockwise or counterclockwise rotation of the second knob 51 can realize the clockwise or counterclockwise rotation of the bidirectional threaded rod 5, thereby facilitating the adjustment of the slider and the clamping plate 25 and facilitating the clamping of workpieces of different sizes.

[0027] The outer surface of the clamping plate 25 is fixedly connected with an anti-skid pad 251, which is a component made of rubber material. The rubber anti-skid pad 251 has a high friction coefficient, which is convenient for effectively increasing the friction between the contact surface with the workpiece and ensuring that the workpiece is stable and does not slide during the welding process.

[0028] There are two groups of clamping components 2, one group of which is arranged at the top of the fixture workbench 1, and the other group of which is arranged above the first groove 12. One group of the clamping components 2 is used to complete the preliminary fixation of the workpiece, and then the other group of the clamping components 2 is adjusted to reach the optimal welding position. Through the coordinated work of the two groups of clamping components 2, it is convenient to firmly clamp two different workpieces for welding.

[0029] An absorption component 6 for absorbing welding gas is arranged above the clamp workbench 1. The absorption component 6 includes a support plate 61 fixedly connected to one side of the clamp workbench 1, a top plate 62 fixedly connected to the top of the support plate 61, a suction fan 63 fixedly connected to the top of the top plate 62, a suction pipe 64 fixedly connected to the air inlet end of the suction fan 63, and a suction hood 65 fixedly connected to the bottom end of the suction pipe 64. The suction pipe 64 runs through the top plate 62. During welding, the suction hood 65 is placed close to the welding area to directly capture the smoke and harmful gases generated during the welding process. The suction pipe 64 extracts these pollutants through the suction fan 63, which is convenient for improving the working environment and protecting the health of operators.

[0030] The air outlet end of the suction fan 63 is fixedly connected to an air outlet pipe 631, one end of the air outlet pipe 631 is fixedly penetrated by a purification box 3, the top of the purification box 3 is fixedly penetrated by an exhaust pipe 31, and activated carbon purification cotton is arranged inside the purification box 3. The activated carbon purification cotton has extremely strong adsorption capacity, which is convenient for effectively removing harmful components in smoke and harmful gases generated during welding. The purified gas is discharged through the air outlet pipe 631, which greatly reduces the concentration of harmful substances.

[0031] When in use, the first group of clamping components 2 is used to complete the preliminary fixing of the workpiece, and then the second group of clamping components 2 is adjusted to complete the work of fixing the workpiece, that is, the clockwise or counterclockwise rotation of the second knob 51 is realized to realize the clockwise or counterclockwise rotation of the bidirectional threaded rod 5, thereby adjusting the slider and the clamping plate 25 to clamp workpieces of different sizes. After the clamping is completed, the motor 41 is started, and the motor 41 drives the unidirectional threaded rod 4 to rotate, thereby driving the fixing plate 42 to rotate along the unidirectional threaded rod 4, thereby adjusting the second group of clamping components 2 to the best welding position. Through the coordinated work of the two groups of clamping components 2, it is convenient to firmly clamp two different workpieces for welding. When welding, the suction hood 65 is placed close to the welding area to directly capture the smoke and harmful gases generated during the welding process. The suction pipe 64 will remove these pollutants. The gas is extracted through the suction fan 63 and enters the purification box 3. After being filtered by the activated carbon purification cotton, it is discharged through the air outlet pipe 631, which is convenient for improving the working environment and protecting the health of the operators. In the initial state, the limit block 26 is threadedly connected to the outer surface of the rotating rod 23, and the forward thread channel 261 is engaged with the reverse thread channel 231. At this time, the outer surface of the limit block 26 is against the outer surface of the connecting plate 22. The locking mechanism of the limit block 26 effectively fixes the rotating rod 23 inside the connecting plate 22. When the welding direction of the workpiece needs to be adjusted, the limit block 26 is rotated to make the reverse thread channel 231 away from the forward thread channel 261, and the initial locking state of the rotating rod 23 is released. The rotating rod 23 is driven to rotate by rotating the first knob 27, thereby driving the clamping plate 25 to rotate, which is convenient for adjusting the welding direction of the workpiece.
