Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

The base plate 1 serves as the mounting carrier for the parts. Four rectangularly distributed support rods are connected to the lower sides of the base plate 1 and the support frame 2 to support the device. The upper parts of the left and right sides of the base plate 1 are arc-shaped and extend downwards, serving as the device's function. The rear side of the base plate 1... A support frame 2 is welded to the surface. Guide plates are symmetrically connected to the upper front side of the support frame 2. The rear side of the mounting frame 6 contacts the guide plates on the support frame 2 for guiding the mounting frame 6. A motor 3 is bolted to the upper side of the support frame 2. A screw 301 is rotatably connected to the support frame 2. The output shaft of the motor 3 rotatably passes through the support frame 2 and is connected to the screw 301 via a coupling. The screw 301 is threaded with a mounting frame 6. A processing device 7 is mounted on the mounting frame 6. Electric slide rails are symmetrically mounted on the upper side of the base plate 1. 71. A movable plate 8 is connected between the electric sliders on two electric slide rails 71. A placement disk 9 is slidably connected to the movable plate 8. An electromagnet 10 is connected to the upper side of the placement disk 9. Fixed plates 11 are symmetrically connected to the front and back sides of the lower side of the movable plate 8. A rotating rod 12 is rotatably connected between the two fixed plates 11. A connecting rod 15 is rotatably connected to the movable plate 8. The upper end of the connecting rod 15 contacts the placement disk 9. A second gear 14 is connected to the upper part of the connecting rod 15. The rear end of the rotating rod 12 is connected to the lower end of the connecting rod 15, and a first gear 13 is connected to the lower end of the connecting rod 15. The first gear 13 is engaged, and four racks 16 are slidably connected to the lower side of the placement disk 9. All four racks 16 are engaged with the second gear 14. The placement disk 9 is located between the four racks 16. A clamping plate 17 is connected to one end of the four racks 16 near the electromagnet 10. The electric slide rail 71 is started to drive the placement disk to move. The electromagnet magnetically attracts the workpiece, which facilitates the placement of the workpiece. The rotating rod 12 is rotated to make the clamping plate 17 clamp and fix the workpiece. The motor 3 is started to drive the processing equipment 7 to move and adjust its height. The processing equipment 7 performs processing operations on the workpiece.

[0020] like Figure 4 As shown, it also includes a connecting plate 19, a mounting plate 20, a contact plate 21, and an elastic element 22. The connecting plate 19 is welded onto the mounting frame 6, the mounting plate 20 is welded onto the left side of the support frame 2, the contact plate 21 is welded onto the connecting plate 19, the contact plate 21 is slidably connected to the mounting plate 20, and the elastic element 22 is wound between the mounting plate 20 and the contact plate 21. The contact plate 21 is used for secondary fixation of the workpiece, and the auxiliary processing equipment 6 processes the workpiece.

[0021] like Figure 3 As shown, it also includes an anti-slip pad 18, and the anti-slip pad 18 is connected to the side of the four-ply plate 17 near the electromagnet 10.

[0022] When this device is needed, the electric slide rail 71 is activated. The electric slider on the electric slide rail 71 moves, causing the moving plate 8 to move forward. The moving plate 8 drives the placement disc 9, electromagnet 10, fixed plate 11, rotating rod 12, first gear 13, connecting rod 15, second gear 14, rack 16, clamping plate 17, and anti-slip pad 18. The workpiece is placed on the placement disc 9, and the electromagnet 10 attracts the workpiece. The electric slide rail 71 is then controlled to rotate in the reverse direction, driving the above components to reset. Subsequently, rotating rod 12 drives the first gear 13 to rotate. Through the meshing transmission of the two first gears 13, the connecting rod 15 and the second gear 14 rotate. The second gear 14 drives the rack 16 to move inward. The rack 16 drives the clamping plate 17 and anti-slip pad 18 to move, clamping and fixing the workpiece to prevent displacement during subsequent processing. The anti-slip pad 18 increases the friction between the clamping plate 17 and the workpiece. Start motor 3. The output shaft of motor 3 rotates, driving screw 301 to rotate. Screw 301 drives mounting bracket 6, processing equipment 7, connecting plate 19, mounting plate 20, contact plate 21, and elastic element 22 to move downward, thereby adjusting the height of processing equipment 7. When contact plate 21 contacts and presses against the workpiece surface, elastic element 22 deforms adaptively. Contact plate 21 cooperates with clamping plate 17 to fix the workpiece on placement disc 9. Start processing equipment 7 to process the workpiece. After processing is completed, control motor 3 to reverse and drive the above components to reset. Elastic element 22 returns to its original shape. Contact plate 21 resets and detaches from workpiece surface under the elastic force of elastic element 22. Reverse rotation of rotating rod 12 resets the above components. Clamping plate 17 detaches from anti-slip pad 18 and workpiece surface. Remove the processed workpiece. Subsequent workpiece processing can be carried out according to the above operation.
