This device is intended to improve processing efficiency, ensure processing accuracy, and ensure the safety of the operation process.

[0003] For example, publication number CN219925068U discloses a clamping device for welding metal doors and windows, comprising a workbench fixedly mounted on several supporting legs, a welding gun provided on the workbench, and a lifting device for the welding gun. A movable plate is slidably mounted on the workbench, and a placement plate is rotatably mounted on the movable plate. The placement plate has several through-grooves uniformly arranged around the circumference, each of which has a movable clamping claw. A drive device capable of controlling the movement of the clamping claw is fixedly mounted on the placement plate. This utility model has a simple structure, an ingenious design, and is easy to operate. It can position and lock metal doors and windows during welding, improving welding efficiency, meeting market demand, and is suitable for promotion.

[0004] However, in the existing technology, the friction between the metal and the clamping surface during long-term use or clamping causes the clamping surface to wear. The wear of the clamping surface will reduce the clamping effect and even cause the metal doors and windows to slip or be damaged during the processing. The current existing clamping devices are inconvenient to disassemble, assemble and replace, which affects the clamping effect and processing efficiency. Utility Model Content

[0014] The utility model adopts a modular assembly design to carry out portable replacement of worn clamping devices. When in use, the palm of the hand holds the groove and pulls the push-pull plate outward. The push-pull plate drives the protrusion to slide outward in the connecting groove and compresses the first return spring. At this time, the protrusion is moved out of the limit groove, and then the mounting block is removed for replacement and maintenance. During installation, it is only necessary to insert the mounting block into the mounting groove and apply a lateral force to the protrusion.

[0015] The utility model provides a flip positioning mechanism to perform secondary limiting on metal doors and windows. When the metal doors and windows are pre-positioned, the handle is held and the horizontal plate is pulled outward. The horizontal plate drives the movable block to slide in the first movable groove through the guide block, the movable block, the rotating rod and the fixed block and stretches the second return spring. At this time, the guide block is flipped 90 degrees in the rotating rod through the movable block, and the end of the guide block is slid and engaged into the second movable groove. At this time, as the second return spring rebounds and resets, the horizontal plate is driven to move closer to the middle, thereby performing secondary limiting and fixing on both sides of the metal doors and windows, further improving the clamping effect.

When in use, the palm of the hand holds the groove 8 and pulls the push-pull plate 7 outward. The push-pull plate 7 drives the protrusion 6 to slide outward in the connecting groove 4 and compresses the first return spring 5. At this time, the protrusion 6 is removed from the limit groove 10, and then the mounting block 9 is removed for replacement and maintenance. During installation, it is only necessary to insert the mounting block 9 into the mounting groove 3 and apply a lateral force to the protrusion 6. When the mounting block 9 fits into the mounting groove 3, the first return spring 5 resets and drives the protrusion 6 to move to the limit groove 10 to complete the positioning assembly, which is convenient for subsequent disassembly and maintenance, and improves the clamping effect and processing efficiency.

[0024] like Figure 1-4 As shown, the outer wall of the mounting block 9 is fixedly connected to the motor 11, the output end of the motor 11 is transmission-connected to the bidirectional screw 12, the surface of the bidirectional screw 12 is symmetrically threaded with a clamping plate 13, the inner cavity of the clamping plate 13 is sequentially provided with a first moving groove 14 and a guide groove 24 from the outside to the inside, and the first moving groove 14 is connected to the second moving groove 23, the inner wall of the second moving groove 23 is provided with a guide groove 24, the inner side wall of the first moving groove 14 is fixedly connected to a plurality of second return springs 15, one end of the second return spring 15 is fixedly connected to a moving block 16, and the moving block 16 is fixed to the first moving groove 14. When the second return spring 15 is engaged, the guide block 20 is turned 90 degrees in the rotating rod 18 through the movable block 19, and the end of the guide block 20 is slidably engaged in the second movable groove 23. At this time, the rebound of the second return spring 15 drives the cross plate 21 to move closer to the middle, thereby performing secondary limit fixation on both sides of the metal doors and windows, avoiding displacement and dislocation of the metal doors and windows, and ensuring the stability of subsequent processing.

[0025] like Figure 1-4As shown, a flip positioning mechanism is provided on the outer side of the moving block 16, and the flip positioning mechanism includes fixed blocks 17 symmetrically fixedly connected to the outer side of the moving block 16. Two adjacent groups of fixed blocks 17 are fixedly connected by a rotating rod 18. The surface of the rotating rod 18 is rotatably connected to a movable block 19. One side of the outer surface of the movable block 19 is fixedly connected to a guide block 20, and the guide block 20 slides in a guide groove 24. The side of the guide block 20 away from the movable block 19 is fixedly connected to a transverse plate 21, and the side of the transverse plate 21 away from the guide block 20 is fixedly connected to a handle 22. Hold the handle 22 And pull the cross plate 21 outward, the cross plate 21 drives the movable block 16 to slide in the first movable groove 14 and stretch the second return spring 15 through the guide block 20, the movable block 19, the rotating rod 18 and the fixed block 17. At this time, the guide block 20 is flipped 90 degrees in the rotating rod 18 through the movable block 19, and the end of the guide block 20 is slid and engaged in the second movable groove 23. At this time, as the second return spring 15 rebounds and resets, the cross plate 21 is driven to move closer to the middle, thereby performing secondary limit fixation on both sides of the metal doors and windows, enhancing the clamping effect and improving processing efficiency.

[0026] Working principle: When in use, first place the metal door and window on the upper surface of the main body 1, and the output end of the motor 11 drives the bidirectional screw rod 12 to rotate, and the bidirectional screw rod 12 drives the clamping plate 13 to move toward each other to pre-clamp and fix the two sides of the metal door and window. Then, hold the handle 22 and pull the horizontal plate 21 outward. The horizontal plate 21 drives the movable block 16 to slide in the first movable groove 14 through the guide block 20, the movable block 19, the rotating rod 18 and the fixed block 17 and stretch the second return spring 15. At this time, the guide block 20 is turned 90 degrees in the rotating rod 18 through the movable block 19, and the end of the guide block 20 is slid and engaged in the second movable groove 23. At this time, as the second return spring 15 rebounds and resets, the horizontal plate 21 is driven to move closer to the middle, thereby performing secondary limit fixation on the two sides of the metal door and window, effectively avoiding the displacement and dislocation of the metal door and window after pre-clamping and fixation;

[0027] When the clamping device is worn and needs to be repaired or replaced, hold the groove 8 with your palm and pull the push-pull plate 7 outward. The push-pull plate 7 drives the protrusion 6 to slide outward in the connecting groove 4 and compresses the first return spring 5. At this time, the protrusion 6 is moved out of the limit groove 10, and then the mounting block 9 is removed for replacement and repair. During installation, you only need to insert the mounting block 9 into the mounting groove 3 and apply a lateral force to the protrusion 6. When the mounting block 9 fits into the mounting groove 3, the first return spring 5 resets and drives the protrusion 6 to move to the limit groove 10 to complete the positioning assembly, which is convenient for subsequent disassembly and maintenance, improves the clamping effect and processing efficiency, has a simple overall structure, is easy to operate, and is suitable for large-scale promotion.
