[0035] Translation rail 3: It is arranged on the middle line of the base 1 and is used for translation movement of the clamp arm 2 along the straight line direction.

[0036] Side rails 4 are symmetrically arranged on both sides of the translation rail 3 and located at both ends and the middle of the translation rail 3, and are used for the sliding movement of the clamp arm 2 in the vertical direction.

[0037] Clamp arm 2: Slidingly mounted on the translation rail 3 and the side rail 4 through a driving assembly, used to fix the various components of the cabinet.

[0038] Clamp cylinder 10: installed on the clamp arm 2, with a clamping plate 11 provided at its output end for clamping cabinet components.

[0039] Driving assembly: includes a rack 5, a gear 15 and a driving motor 13, used to control the movement of the clamp arm 2.

[0040] Drive components

[0041] Rack 5: fixedly mounted on the top of the translation rail 3 and the side rail 4, meshing with the gear 15 for transmitting power.

[0042] Gear 15 is rotatably mounted on the side wall of the opening 19 at the bottom of the clamp arm 2 via the rotating shaft 16 , meshes with the rack 5 , and converts the power of the drive motor 13 into movement of the clamp arm 2 .

[0043] Driving motor 13: fixedly mounted on the outer wall of the clamp arm 2, with its output end connected to the rotating shaft 16 via a coupling, for driving the gear 15 to rotate.

[0044] Guidance and connection

[0046] Slide rod 17: The bottom of the clamp arm 2 is slidably connected to the guide groove 6 through the slide rod 17 to ensure the stability and accuracy of the clamp arm 2 during movement.

[0047] Working process

[0048] Initial position setting:

[0049] Place the base 1 on the workbench and select a suitable position according to the size and shape of the cabinet.

[0050] The clamp arm 2 is installed on the translation slide rail 3 and the side slide rail 4 through the driving assembly to ensure that the clamp arm 2 can slide freely on the slide rail.

[0051] Clamp arm 2 positioning:

[0052] According to the position of the cabinet component to be fixed, the drive motor 13 is started, and the drive motor 13 drives the rotating shaft 16 to rotate through the coupling.

[0053] The gear 15 on the rotating shaft 16 is engaged with the rack 5 , so that the clamp arm 2 moves to a predetermined position along the translation slide 3 and the side slide 4 .

[0054] During the movement, the slide bar 17 at the bottom of the clamp arm 2 slides in the guide groove 6 to ensure the smoothness and accuracy of the movement.

[0055] Clamping operation:

[0056] When the clamp arm 2 reaches the predetermined position, the clamp cylinder 10 is activated so that the output end of the clamp cylinder 10 pushes the clamping plate 11 close to the cabinet component.

[0057] The clamping plate 11 fixes the cabinet components in a predetermined position, ensuring the precise alignment of the welding parts.

[0058] Welding operations:

[0059] After the clamping operation is completed, welding work is carried out.

[0060] During the welding process, the clamp arm 2 remains stable and motionless to ensure the welding quality.

[0061] Release and reset:

[0062] After welding is completed, the clamp cylinder 10 is started in the reverse direction to separate the clamping plate 11 from the cabinet component.

[0063] The driving motor 13 is started in reverse to return the clamp arm 2 to the initial position for the next operation.

[0068] Slideways 22 and Auxiliary Rods: Two slideways 22 are symmetrically provided on the sidewalls of the lifting slot 9. The mounting frame 7 is slidably connected to the slideways 22 via auxiliary rods. This design allows the mounting frame 7 to slide smoothly along the slideways 22 under the action of the lifting cylinder 8, ensuring the stability of the clamp cylinder 10 during the lifting process.

[0069] Optimize the technical solution again: Improved design of splint 11

[0070] Buffering rubber pad 21: The inner side of the splint 11 is wrapped with a buffering rubber pad 21. The design of the buffering rubber pad 21 can protect the clamped cabinet components from damage and reduce scratches or other damage that may occur during the clamping process.

[0071] Limiting plate 12 and T-shaped splicing groove: A limiting plate 12 is provided on the top of the clamping plate 11. A T-shaped splicing groove is provided on the top of the clamping plate 11. The limiting plate 12 is slidably connected to the T-shaped splicing groove via a splicing rod 20.
