[0018] The device includes an I-shaped rod 103 and an L-shaped frame 301. Two L-shaped clamping rods 201 are slidably connected to the I-shaped rod 103 via slots. A mating disc 303 is rotatably connected to the L-shaped frame 301 via bearings. The mating disc 303 is connected to the two L-shaped clamping rods 201 via a transmission structure. The transmission structure enables the two L-shaped clamping rods 201 to slide synchronously closer to or further away from each other on the I-shaped rod 103. A rectangular groove 305 is provided on the mating disc 303. An electric drive structure is slidably connected to the L-shaped clamping rods 201 via slots. The electric drive structure can drive the mating disc 303 to rotate through the rectangular groove 305. Multiple gripping rods 306 are welded and fixed to the mating disc 303.

[0019] When clamping is required, the electric drive structure drives the mating disc 303 to rotate, thereby causing the transmission structure to move. This causes the two L-shaped clamping rods 201 to slide closer to each other on the I-shaped rod 103, thereby using the two L-shaped clamping rods 201 to clamp and fix the workpiece, achieving the clamping effect in metal processing.

[0020] In actual use, if the electric drive structure that drives the mating disc 303 to rotate suddenly fails during metal processing, making it impossible to drive the two L-shaped clamping rods 201 via electric drive, the electric drive structure can be slid off the L-shaped frame 301 to separate it from the rectangular groove 305. Then, the operator can temporarily drive the mating disc 303 to rotate by holding multiple gripping rods 306, thereby temporarily driving the transmission structure to move. After the two L-shaped clamping rods 201 move to clamp the workpiece, the rotated mating disc 303 is fixed, facilitating subsequent workpiece processing. This allows the equipment to achieve manual and automatic clamping functions. Even if the electric drive fails, the clamping work can still be completed manually, ensuring the stability of the clamping operation and providing a stable guarantee for subsequent metal workpiece processing.

[0021] After removing the malfunctioning electric drive structure and manually clamping it in place, the staff can repair and maintain the electric drive structure to restore its normal operation. Then, the electric drive structure can be moved back to allow it to engage with the rectangular groove 305 again, ensuring the long-term effectiveness of subsequent clamping operations.

[0022] It also includes a fixing threaded hole 302 opened on the L-shaped frame 301.

[0023] After manually rotating multiple gripping rods 306, and using the transmission structure to enable the two L-shaped clamping rods 201 to manually clamp the workpiece, the rotating mating disc 303 can be fixed by screwing bolts into the fixed threaded hole 302, thereby ensuring the clamping stability of the workpiece, avoiding vibration of the workpiece during subsequent processing, and ensuring the processing effect.

[0024] The electric drive structure includes a sliding part 401 that is slidably connected to the L-shaped frame 301 through a slot. A rotating plate 402 is rotatably connected to the sliding part 401 through a bearing. A rectangular protrusion 404 is integrally formed on the rotating plate 402. The rectangular protrusion 404 can be inserted into the rectangular groove 305. An auxiliary threaded hole is provided on the sliding part 401.

[0025] Under normal conditions, the rectangular protrusion 404 is inserted into the rectangular groove 305. When it is necessary to drive the mating disc 303 to rotate, the rotating plate 402 is rotated, which in turn drives the rectangular protrusion 404 to rotate. This causes the rectangular protrusion 404 to drive the rectangular groove 305 to rotate, thereby completing the electric drive clamping effect and providing a stable guarantee for the subsequent metal processing.

[0026] The sliding part 401 is fixed by screwing bolts into the auxiliary threaded hole. When it is necessary to manually drive the mating disc 303 to rotate, the bolts are loosened first to remove the fixing effect on the sliding part 401. Then the sliding part 401 is slid. After the sliding part 401 slides until the rectangular protrusion 404 is pulled out from the rectangular groove 305, the bolts are tightened again to fix the sliding part 401 for a second time, which brings convenience to subsequent maintenance operations.

[0027] The electric drive structure also includes a drive motor 403 that is bolted to the sliding part 401, and the output shaft of the drive motor 403 is fixed to the rotating plate 402 via a coupling.

[0028] The output shaft of the drive motor 403 is rotated by starting the drive motor 403, which in turn drives the rotating plate 402 to rotate. The rectangular protrusion 404 and the rectangular groove 305 are used to drive the mating disc 303 to rotate, so that the two L-shaped clamping rods 201 can complete the subsequent clamping and fixing effect by electric drive.

[0029] When the drive motor 403 malfunctions and causes the sliding part 401 to slide open, the drive motor 403 can be repaired and maintained to restore the subsequent electric drive effect in a timely manner.

[0030] The transmission structure includes a gear 304 welded and fixed to the mating disc 303. Each L-shaped clamp 201 is welded and fixed with a rack 203. The two racks 203 are symmetrically arranged and both racks 203 mesh with the gear 304.

[0031] When the mating disc 303 rotates, it can drive the gear 304 to rotate synchronously. Then, through the meshing transmission relationship between the gear 304 and the two racks 203, the two racks 203 respectively drive the two L-shaped clamping rods 201 to slide, so that the two L-shaped clamping rods 201 move away from or closer to each other, thus completing the clamping or releasing effect on the workpiece.

[0032] Each of the L-shaped clamps 201 is bonded with a rubber layer 202.

[0033] During clamping, the rubber layer 202 on the two L-shaped clamping rods 201 can contact the workpiece, thereby gently clamping the workpiece, buffering the clamping force, and preventing damage to the workpiece.

[0034] It also includes a processing table 101 welded and fixed to the lower side of the I-shaped rod 103, and the processing table 101 is welded and fixed to the L-shaped frame 301.

[0035] The machining table 101 allows workers to place workpieces on it and then clamp them using two L-shaped clamping rods 201, further facilitating the clamping operation and ensuring the accuracy and stability of the clamping, thus facilitating subsequent processing.

[0036] It also includes multiple support legs 102 that are welded and fixed to the underside of the processing table 101.

[0037] Multiple support legs 102 can provide stable support for the processing table 101, so that the processing table 101 is stably supported to a certain height, which further facilitates subsequent processing operations. At the same time, the multiple support legs 102 can be fixed by screwing bolts into the bottom of the multiple support legs 102.

[0038] It also includes a vertical rod 104 fixed to the I-shaped rod 103, an auxiliary pressure plate 501 slidably connected to the vertical rod 104, and a compression spring 502 fixed between the auxiliary pressure plate 501 and the vertical rod 104.

[0039] After the workpiece is placed on the processing table 101, the auxiliary pressure plate 501 can be used to press against the upper side of the workpiece, and the elastic force provided by the compression spring 502 can be used to firmly press the workpiece, thereby further improving the clamping and fixing effect of the workpiece and bringing convenience to subsequent processing.

[0040] At the same time, when performing manual clamping operations, the clamping effect can be further enhanced by the auxiliary pressure plate 501, further enhancing the manual-automatic function.

[0041] The compression spring 502 consists of a diagonal bar and a straight bar.

[0042] When the workpiece is fed in, it can be fed in from the inclined bar of the auxiliary pressure plate 501, so that the workpiece can automatically lift the auxiliary pressure plate 501 upward. When the tool enters the lower side of the straight bar area, the elastic force applied by the compression spring 502 can be used to assist in clamping the workpiece, and further complete the stable clamping function.
