[0023] Specifically, the lifting and tilting device 2 includes a connecting frame 21, a lifting plate 22, a motor 23, a tilting assembly 24 and a screw rod 25. The connecting frame 21 is installed above the connecting block 6, and the motor 23 is installed above the connecting frame 21. The screw rod 25 is installed on the side of the motor 23 close to the connecting frame 21. The lifting plate 22 is installed on the outside of the screw rod 25 and on the inside of the connecting frame 21 through a thread. The lifting plate 22 and the clamping plate assembly 3 are connected through the tilting assembly 24.

[0025] Specifically, the outer shape of the connecting frame 21 is L-shaped, and the lifting plate 22 and the connecting frame 21 are closely attached to each other.

[0026] By adopting the above technical solution, the device can perform certain limiting and guiding work on the movement of the lifting plate 22 through the connecting frame 21, thereby preventing the lifting plate 22 from rotating and deviating during the movement.

[0027] Specifically, the tilting assembly 24 includes a vertical plate 241, a first magnet ring 242, a connecting shaft 243 and a second magnet ring 244. The vertical plate 241 is installed on the side of the lifting plate 22 close to the clamping plate assembly 3, the connecting shaft 243 is installed on the side of the clamping plate assembly 3 close to the vertical plate 241, the second magnet ring 244 is installed on the outer side of the connecting shaft 243, and the first magnet ring 242 is installed at the edge of the side of the vertical plate 241 close to the second magnet ring 244.

[0029] When this embodiment is used, when the device is needed to clamp the workpiece during workpiece welding, the clamping plate assembly 3 is operated to clamp the workpiece, and then the driving assembly 8 is operated.

Then the staff rotates the clamping plate assembly 3 so that it rotates with the connecting shaft 243 in the tilting assembly 24 to a suitable tilting angle. The connecting shaft 243 is connected to the vertical plate 241 by a bearing. The mutual attraction between the first magnet ring 242 and the second magnet ring 244 can enhance the rotation resistance and prevent the occurrence of accidental rotation. The clamping work is completed.

[0030] Example 2

[0031] The difference between this embodiment and Embodiment 1 is that the purification treatment device 4 includes an L-shaped box 41, a connecting plate 42, activated carbon 44, a partition 45 and a fan 46, an L-shaped box 41 is arranged between the splint assembly 3 and the pointer 5, the splint assembly 3 and the L-shaped box 41 are connected by a connecting plate 42, two partitions 45 are installed on the inner side of the L-shaped box 41, the inner side of the L-shaped box 41 and the position between the two partitions 45 are filled with activated carbon 44, and a fan 46 is installed on the side of the L-shaped box 41 close to the pointer 5.

[0032] By adopting the above technical solution, the device can purify the waste gas generated during the processing to a certain extent through the cooperation of structures such as activated carbon 44 and partition 45 when necessary, so as to better meet the working needs in different situations.

[0033] Specifically, the purification device 4 further includes a blocking block 43 , and the blocking block 43 is installed via threads on one side of the L-shaped box 41 and at a position on the side of the activated carbon 44 away from the connecting plate 42 .

[0034] By adopting the above technical solution, the staff can unscrew the blocking block 43 to replace the activated carbon 44 when necessary, thereby reducing the difficulty of replacing the activated carbon 44 and alleviating the labor burden of the staff.

[0035] When this embodiment is used, when the exhaust gas needs to be purified during welding work, the fan 46 in the purification treatment device 4 is started. Under the action of the fan 46, the exhaust gas enters the L-shaped box 41 and is then purified by the activated carbon 44 between the two partitions 45. After the purification is completed, the possibility of adverse effects caused by the exhaust gas is reduced. When necessary, the staff can unscrew the blocking block 43 and replace the activated carbon 44. The connecting plate 42 plays a connecting role.

[0036] The structures and principles of the base assembly 1 composed of a first chamber and a base, the splint assembly 3 composed of a fixed plate, a second handle, a through hole, a second chamber, a threaded rod, a moving block, a connecting rod, an opening, a splint and an anti-slip pad, a pointer 5, a rotating shaft assembly 7 composed of a second rotating shaft, a second gear and a second opening, and a driving assembly 8 composed of a first opening, a first handle, a first gear and a first rotating shaft in the utility model have been disclosed in an angle-adjustable workpiece clamping device disclosed in Chinese patent application No. 201820067944.4. The working principle is to first rotate the second handle to rotate the threaded rod. Since there are two moving blocks threadedly connected to the threaded rod, the threads at the upper and lower ends of the threaded rod are set in opposite directions, and the two The two moving blocks are symmetrically arranged at the upper and lower ends of the threaded rod. When the threaded rod rotates, the two moving blocks are restricted by the connecting rod, and the two moving blocks can only move to one side or the opposite side. The direction of movement of the two moving blocks depends on the direction of rotation of the second handle. When the two moving blocks move to the opposite side, the two clamps clamp the tool to be polished. By rotating the first handle, the first rotating shaft and the first gear are rotated. Since the second gear is meshed with the first gear, the first gear drives the second gear to rotate, thereby rotating the vertical plate, thereby changing the vertical angle of the tool to be polished, which is convenient for processing the tool into different arcs. A pointer is arranged on the vertical plate, and an angle scale line corresponding to the pointer is arranged on the base to facilitate angle adjustment.

[0037] The working principle and use process of the utility model are as follows: when the device is needed to clamp the workpiece during workpiece welding, the clamping plate assembly 3 is operated to clamp the workpiece, and then the driving assembly 8 is operated. The driving assembly 8 drives the clamping plate assembly 3 and the workpiece thereon to rotate to a suitable direction through the rotating shaft assembly 7 and the connecting block 6 and other structures. An angle scale corresponding to the pointer 5 is provided on the base assembly 1 to facilitate the judgment of the angle. Then the staff starts the motor 23 in the lifting and tilting device 2, thereby driving the screw rod 25 to rotate. The screw rod 25 is threadedly connected to the lifting plate 22, and the lifting plate 22 and the connecting frame 21 are tightly attached to each other, so the screw rod 25 drives the lifting plate 22 and other structures to move, thereby adjusting the height of the clamping plate assembly 3 and the workpiece thereon, and then The staff rotates the clamping plate assembly 3 so that it and the connecting shaft 243 in the tilting assembly 24 are rotated to a suitable tilting angle. The connecting shaft 243 is connected to the vertical plate 241 by a bearing. The mutual attraction between the first magnet ring 242 and the second magnet ring 244 can enhance the rotation resistance and prevent the occurrence of accidental rotation. The clamping work is completed; when the exhaust gas needs to be purified during the welding work, the fan 46 in the purification treatment device 4 is started. Under the action of the fan 46, the exhaust gas enters the L-shaped box 41 and is then purified by the activated carbon 44 between the two partitions 45. After the purification is completed, the possibility of adverse effects caused by the exhaust gas is reduced. When necessary, the staff can unscrew the blocking block 43 to replace the activated carbon 44. The connecting plate 42 plays a connecting role.
