Description

Technical Field

[0001] This utility model belongs to the technical field of sheet metal processing auxiliary equipment, specifically relating to a transfer device for laser cutting of sheet metal parts. Background Technology

[0002] Vacuum suction cup lifters for sheet metal parts are industrial lifting equipment specifically designed for handling large sheet metal parts that are flat or slightly curved. Their core working principle is to use vacuum negative pressure to adsorb the workpiece, thereby achieving safe, efficient, and non-destructive gripping and movement. Compared to traditional mechanical claws or magnetic lifters, their biggest advantage lies in their ability to contact the workpiece through evenly distributed adsorption force, avoiding scratches, deformation, or magnetization of the sheet metal parts that may be caused by clamping pressure or magnetism. It is a non-contact, flexible transfer device for automated sheet metal part cutting and production.

[0003] However, existing sheet metal vacuum suction cup hangers are usually fixed to the crossbeam with screws. When the position of the suction cup needs to be adjusted, each screw needs to be removed and adjusted, which is time-consuming and laborious. When dealing with sheet metal parts of different sizes or shapes, it is not possible to adjust the position of the suction cup by quickly adjusting the structure, which affects the ease of use of the equipment.

Through the configuration of the middle outer frame, rack, locking external gear, sliding internal gear, locking block, spring, welding plate, suction cup outer frame, slide rod, and pull handle, the operator only needs to operate the pull handle to drive the slide rod, which will disengage the locking block from the locking external gear, thereby releasing the rotation restriction of the sliding internal gear. This allows for flexible adjustment of the middle outer frame and suction cup outer frame along the crossbeam or suction cup mounting rod. After adjustment, releasing the pull handle will cause the spring to automatically push the locking block back to its original position and re-engage with the locking external gear, achieving reliable locking of the sliding internal gear. This structure not only effectively ensures the positioning stability of the vacuum suction cup during sheet metal part transfer, preventing displacement or shaking, but also significantly enhances the adaptability to sheet metal parts of different sizes and shapes.

This allows the transfer device to adapt to the laser cutting and handling needs of various specifications of sheet metal parts, thereby improving handling efficiency. The telescopic structure also maintains a safe distance between the operator and the sheet metal parts when holding the handle, effectively avoiding collisions during the transfer process and enhancing operational safety.

[0024] In this embodiment, the sheet metal vacuum suction cup lifter is an industrial lifting device specifically designed for handling large sheet metal parts that are flat or slightly curved. When using the sheet metal vacuum suction cup lifter, the operator first connects the entire lifter to the lifting equipment through the lifting hole 1 on the hanger 4. The vacuum generator 2 installed on the crossbeam 13 can be activated by the suction cup button 7. The vacuum negative pressure generated by the generator is transmitted to the vacuum suction cup 11 through the vacuum connecting pipe 3. The operator lowers the lifter so that the vacuum suction cups 11 on the suction cup outer frame 24 at both ends of the suction cup mounting rods 14 on both sides of the crossbeam 13 are tightly attached to the surface of the sheet metal part. After the vacuum suction cups 11 firmly adhere to the workpiece, the lifting equipment can be operated to lift the lifter. The operator can stabilize the sheet metal part transfer process and control the direction of the sheet metal part by holding the handle 5, thereby safely transferring the sheet metal part.

[0025] like Figure 1 , Figure 2 , Figure 3and Figure 4 As shown, the middle outer frame 16 is welded to the suction cup mounting rod 14. The suction cup mounting rod 14 can be sleeved with the crossbeam 13 through the middle outer frame 16. The rack 15 is fixedly installed to the crossbeam 13 by screws.

The shaft of the sliding internal gear 20 on one side passes through one side of the middle outer frame 16. The locking external gear 19 is welded to the shaft of the sliding internal gear 20. The locking external gear 19 and the sliding internal gear 20 rotate synchronously. The locking gear block 21 can mesh with the locking external gear 19. The slide rod 18 is welded to the locking block 21, the spring 22 is sleeved with the slide rod 18, the welding plate 23 is welded to the middle outer frame 16, the slide rod 18 passes through the welding plate 23 and can slide on the welding plate 23, the pull handle 17 is welded to the slide rod 18, the suction cup outer frame 24 is provided with a sliding internal gear 20 and a locking external gear 19 in the same way, the locking external gear 19 is also provided with a locking structure, the suction cup mounting rod 14 is respectively installed with racks 15 on both sides, and the sliding internal gear 20 on the suction cup outer frame 24 meshes with the racks 15.

This releases the position lock of the sliding internal gear 20 on the rack 15, enabling flexible adjustment of the middle outer frame 16 and suction cup outer frame 24 along the crossbeam 13 or suction cup mounting rod 14. After adjustment, the pull handle 17 is released, and the spring 22 pushes the locking block 21 to re-engage with the locking external gear 19, firmly locking the sliding internal gear 20. This ensures that the vacuum suction cup 11 maintains stable positioning during the transfer of sheet metal parts, preventing displacement or shaking. This not only improves the adaptability to sheet metal parts of different sizes and shapes but also greatly shortens the adjustment time, improves the convenience of equipment adjustment, and saves time and effort.
