The rotating shaft 8 is vertically arranged, and a gear 9 meshing with the rack column 6 is fixedly installed on the rotating shaft 8. When the hardware decoration piece needs to be moved into or out of the frame 1, the motor 7 is powered on to drive the rotating shaft 8 to rotate, thereby adjusting the position of the moving platform 5, so that the operator can more conveniently assemble or disassemble the hardware decoration piece; The moving platform 5 is provided with a moving assembly for driving the two moving plates 18 to move horizontally; The moving assembly includes two guide rods 14 fixedly installed in the moving platform 5, and a slider 15 is slidably sleeved on the guide rod 14, a connecting end 17 is integrally connected to the slider 15, and a moving plate 18 is arranged on the connecting end 17. The guide rod 14 is horizontally arranged, and the moving plate 18 and the connecting end 17 extend to the upper end position outside the moving platform 5.

It is supplemented that the number of the rotating rods 19 is adjusted according to the specifications of the moving plate 18, so that the brackets 20 on the rotating rods 19 can clamp multiple sets of hardware decorative parts, thereby making it more convenient for operators to assemble the hardware decorative parts. The brackets 20 are fixedly mounted on the rotating rods 19, and the brackets 20 are fixedly mounted with symmetrically arranged sleeves 21 and telescopic rods 27, and the sleeves 21 are slidably sleeved with a moving rod 22, and a spring 23 is welded between the moving rod 22 and the sleeves 21; A pressure rod 25 is installed in the moving rod 22, and a limit plate 26 that is movably opposed to the hardware decoration is fixedly installed on the pressure rod 25. A pressure end 24 is fixedly installed on the moving rod 22. A traction rod 28 is connected between the output end of the telescopic rod 27 and the two pressure ends 24. The pressure rod 25 and the moving rod 22 extend to the lower end position outside the sleeve 21. The sleeve 21 guides the moving rod 22, so that the moving rod 22 can smoothly pull the pressure rod 25 and the limit plate 26 when moving.

The two ends of the traction rod 28 are respectively connected to the output end of the telescopic rod 27 and the pressure end 24 by pins. Before the hardware decoration is limited, the limit plate 26 is selected according to the specifications of the hardware decoration, so that the output end of the telescopic rod 27 can drive the two limit plates 26 to clamp the hardware decoration from both sides after the contraction of the output end of the telescopic rod 27. The frame 1 is provided with a driving assembly 4 for driving the welding machine 3 to correspond to the hardware decorative piece; The driving assembly 4 includes a transverse cylinder fixedly mounted on the frame 1, a guide block connected to the transverse cylinder is provided on the sliding sleeve in the frame 1, a longitudinal cylinder connected to the welder 3 is fixedly mounted on the guide block, the transverse cylinder can adjust the position of the welder 3, and the longitudinal cylinder can adjust the height of the welder 3, a sealing door is installed on the pin shaft on the frame 1, and a transparent observation window is provided on the sealing door, and a filter box 2 for filtering smoke is provided on the frame 1; The sealing door can seal the frame 1, and the filter box 2 can filter the smoke in the frame 1, so that the operator next to the frame 1 can ensure his own safety during operation; A set of hardware decorations is installed in the corresponding two brackets 20, and the hardware decorations are clamped by the limit plate 26, and then the rotating rod 19 drives the hardware decorations to rotate by the driving of the telescopic rod 1 27, so that the welding device 3 can process multiple sets of hardware decorations in sequence, effectively improving the efficiency of processing the hardware decorations; It should be noted that the specific models and specifications of the filter box 2, welder 3, transverse cylinder, longitudinal cylinder, motor 1 7, motor 2 11, telescopic rod 1 27, and telescopic rod 2 30 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0021] The present invention can be explained by the following operation mode: The specifications of the limit plate 26 are selected according to the specifications of the hardware decoration parts; When the hardware decoration part is a rectangular parallelepiped or plate-shaped structure, the limiting plate 26 is selected to be a plate-shaped structure; When the hardware decoration part is a cylindrical structure, the limiting plate 26 is selected to be an arc structure; Extend the pressure rod 25 equipped with the limit plate 26 into the moving rod 22, and use a fixing bolt to connect the moving rod 22 and the pressure rod 25; Extend the hardware decoration parts into two corresponding brackets 20 respectively; The output end of the telescopic rod 27 contracts and drives the traction rod 28 to deflect. The position difference generated when the traction rod 28 deflects can pull the pressure end 24. The pressure end 24 drives the moving rod 22 to slide in the sleeve 21. The spring 23 is stressed, so that the moving rod 22 drives the pressure rod 25 and the limit plate 26 to slide in the bracket 20, so that the two limit plates 26 clamp one end of the hardware decoration. Repeat the above steps to install all three sets of hardware decorations; The output end of the motor 7 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the gear 9 to pull the rack column 6. When the rack column 6 moves, it drives the moving platform 5 to slide in the frame 1, and the moving platform 5 drives the hardware decoration parts to move into the frame 1; The output end of the second motor 11 drives the screw rod 12 to rotate, and the screw rod 12 drives the two nuts 13 to move toward or in opposite directions when rotating; When the two nuts 13 move in opposite directions, the connecting end 17 is driven to slide in the long hole, and the connecting end 17 drives the two moving plates 18 to move toward each other. When the two moving plates 18 move toward each other, the two hardware decorative parts are driven to contact each other. The horizontal cylinder can adjust the position of the guide block, and the vertical cylinder can adjust the height of the welder 3; The sealing door seals the frame 1, and the filter box 2 can filter the smoke in the frame 1; The output end of the telescopic rod 2 30 is extended and retracted to drive the active rack 31 to move. When the active rack 31 moves, it drives the rotating rod 19 to rotate through the meshing gear 29. The rotating rod 19 drives the bracket 20 and the hardware decoration to rotate, and then the hardware decoration is welded; When the guide block moves, it drives the welder 3 to weld the three sets of hardware decoration parts on the moving platform 5 respectively; After the metal decorations on the movable platform 5 are welded, the output end of the motor 7 drives the rotating shaft 8 to rotate, thereby moving the movable platform 5 out of the frame 1, and the operator removes the welded metal decorations.
