[0002] Sheet metal is a common flat material, usually with a rectangular cross-section, and is widely used in various fields such as construction, manufacturing, and decoration because it has a flat surface, high strength, and diverse uses. Sheet metal processing is a common manufacturing and processing method, which usually involves cutting, shaping, joining, and surface treatment of sheet metal.

Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0022] Example 1

[0023] like Figure 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides a clamping device for sheet metal processing, including a hollow frame 1. A threaded column 2 is movably connected to the inner cavity of the hollow frame 1 through a bearing. A threaded sleeve 3 is threadedly connected to the surface of the threaded column 2. A motor 4 is fixedly connected to the left side of the hollow frame 1. The output shaft of the motor 4 passes through the inner cavity of the hollow frame 1 and is drivenly connected to the left end of the threaded column 2. A clamping mechanism 5 is provided on the front side of the threaded sleeve 3. A support block 6 is fixedly connected to the right side of the hollow frame 1. A support column 7 is movably connected to the inner cavity of the support block 6 through a bearing. A positioning mechanism 8 is provided on the top of the support block 6. A handle 9 is fixedly connected to the top of the support column 7. A base 10 is fixedly connected to the bottom of the support column 7.

[0024] like Figure 1-4 As shown, the clamping mechanism 5 is used to clamp the plate. After clamping, the left and right positions of the plate can be adjusted by starting the motor 4. The motor 4 can drive the threaded column 2 to rotate. When the threaded column 2 rotates, it can adjust the position of the threaded sleeve 3, thereby adjusting the position of the clamping mechanism 5 and the clamped plate. After moving the positioning mechanism 8 upward, the angle of the hollow frame 1 can be adjusted. After the adjustment is completed, the positioning mechanism 8 is reset, and the hollow frame 1 can be repositioned.

[0025] Example 2

[0026] Reference Figure 2 and 3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0027] In this embodiment, the clamping mechanism 5 includes a fixing plate 501, which is disposed on the front side of the threaded sleeve 3. Clamping plates 502 are disposed on both sides of the fixing plate 501. A threaded rod 503 is movably connected to the inner cavity of the fixing plate 501 through a bearing. The inner cavities of the two upper clamping plates 502 are threadedly connected to the surface of the threaded rod 503, and the back sides of the two lower clamping plates 502 are fixedly connected to the fixing plate 501.

[0028] A connecting block 504 is fixedly connected to the back of the fixing plate 501. The back of the connecting block 504 is fixedly connected to the threaded sleeve 3. A limit post 11 is slidably connected to the inner cavity of the connecting block 504. Both ends of the limit post 11 are fixedly connected to the inner wall of the hollow frame 1.

[0029] like Figure 2 and 3 As shown, rotating the threaded rod 503 can adjust the height of the upper clamping plate 502, allowing it to gradually approach the lower clamping plate 502 and clamp the plate between the two clamping plates 502. The limiting post 11 plays a limiting role in the threaded sleeve 3, preventing it from deflecting at an angle during left and right movement.

[0030] Example 3

[0031] Reference Figure 3 and 4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0032] In this embodiment, the positioning mechanism 8 includes a movable ring 801, which is sleeved on the surface of the support column 7 and slidably connected to the surface of the support column 7. The front and back sides of the movable ring 801 are fixedly connected with locking blocks 802. The top of the support block 6 is provided with a locking groove 803, and the bottom of the locking block 802 extends into the inner cavity of the locking groove 803 and engages with the inner cavity of the locking groove 803.

[0033] A spring 804 is fitted on the surface of the support column 7. The top of the spring 804 is fixedly connected to the handle 9, and the bottom of the spring 804 is fixedly connected to the movable ring 801. An auxiliary frame 805 is fixedly connected to the top of the locking block 802.

[0034] The front of the support column 7 is provided with a through groove 12, and the inner cavity of the through groove 12 is slidably connected to a limiting block 13. The front and back of the limiting block 13 are fixedly connected to the inner wall of the movable ring 801.

[0035] like Figure 3 and 4As shown, by pulling the auxiliary frame 805 upward, the movable ring 801 can be moved, and the movable ring 801 can then move the locking block 802 until it moves out of the slot 803. After it moves out, the hollow frame 1 can be rotated. During this process, the spring 804 will be squeezed by the movable ring 801 and deformed. The return force of the spring 804 can reset the movable ring 801, so that it can drive the locking block 802 back into the slot 803 to position the hollow frame 1.

[0036] In use, the sheet material is first placed between the two clamping plates 502. Then, the threaded rod 503 is rotated, which adjusts the height of the upper clamping plate 502, allowing it to gradually approach the lower clamping plate 502 and clamp the sheet material between the two clamping plates 502. After clamping, the sheet material can be processed. During processing, if the left and right positions of the sheet material need to be adjusted, the motor 4 is started. The motor 4 drives the threaded column 2 to rotate. When the threaded column 2 rotates, it can adjust the position of the threaded sleeve 3, thereby adjusting the clamping mechanism 5 and the clamped material. To adjust the position of the plate, when it is necessary to adjust the processing angle of the plate, first pull the auxiliary frame 805 upward. The auxiliary frame 805 can drive the movable ring 801 to move, and the movable ring 801 can then drive the locking block 802 to move until it moves out of the slot 803. After it moves out, the hollow frame 1 can be rotated. During this process, the spring 804 will be squeezed by the movable ring 801 and deformed. The return force of the spring 804 can reset the movable ring 801, so that it can drive the locking block 802 to re-enter the slot 803 to position the hollow frame 1.
