The cross plate 17 is arranged at the output end of the syringe cylinder 15 and the upper end surface of the cross plate 17 is in contact with the slide rod 16. Specifically, the cross plate 17 can be driven to move up and down along the linear direction of the slide rod 16 by extending and retracting the syringe cylinder 15, so as to subsequently grab the blank. The linear bearing 14 can limit the slide rod 16, so that the structure is more stable when the cross plate 17 moves.

[0031] Among them Figure 1 As shown, the drive assembly includes a motor 5, a motor mounting plate 6, a connecting block 9, a screw support seat 10 and a screw 11. The motor mounting plate 6 is installed on the lower end surface of the top plate 4 and is located at the center position of the two slide rails 7. The motor 5 is installed on the side of the motor mounting plate 6. The screw support seat 10 is installed on the lower end surface of the top plate 4 and the screw support seat 10 and the motor 5 are on the same horizontal center line. The screw 11 is sleeved inside the screw support seat 10 and the end of the screw 11 close to the rotary chuck 2 is connected to the output end of the motor 5. Specifically, the motor 5 can be set to drive the screw 11 to rotate, and then the connecting block 9 can drive the mounting base 13 to move left and right along the linear direction of the screw 11, so as to facilitate the subsequent transportation of the blank.

[0033] Among them Figure 1As shown, the upper end surface of the cross plate 17 is installed with a slide cylinder 19 and the output end of the slide cylinder 19 is installed with a top block assembly 18. The slide cylinder 19 can drive the top block assembly 18 to move left and right. Specifically, when the rotary electric cylinder 12 rotates, it can be retracted by the slide cylinder 19, and the top block assembly 18 can push the blank to the rotary chuck 2 for locking, and repeat the processing of the other end of the blank without manual reinstallation, thereby improving the production efficiency of the equipment.

Specifically, the blank can be placed by the placement base plate 21 for subsequent grasping, and the set stop block 22 can contact the lower end surface of the blank to prevent the blank from being displaced when the connecting tube 23 grasps the blank, thereby affecting the subsequent progress.

[0034] Working principle: First, a rotating chuck 2 is installed on the upper end surface of the processing base plate 1, which is used to clamp the blank and then rotate it. The support column 3 is used to support the top plate 4. The motor 5 can drive the screw rod 11 to rotate. The screw support seat 10 is used to limit the screw rod 11, so that the connecting block 9 can drive the mounting base 13 to slide left and right along the linear direction of the slide rail 7 with the slider 8. The slider 8 is used to support the mounting base 13, so that the structure is more stable when the mounting base 13 is displaced. The syringe cylinder 15 is extended and retracted to drive the cross plate 17 to move up and down along the linear direction of the slide rod 16, so that the blank can be grabbed later. The linear bearing 14 can limit the slide rod 16, so that the structure is more stable when the cross plate 17 moves. The rotary electric cylinder 12 can drive the connecting cylinder 23 to rotate. The outer wall of the clamping tube 20 is circumferentially provided with a connecting tube 23, and a spring 24 is provided inside the connecting tube 23, and the upper end surface of the spring 24 contacts the limit column 25. The reaction force of the spring 24 can make the multiple groups of limit columns 25 fit tightly with the blank, which can firmly limit the blank. When the other end of the blank needs to be processed, the blank can be rotated by the rotary electric cylinder 12. After the rotary electric cylinder 12 rotates, it can be retracted by the slide cylinder 19, and the top block assembly 18 can push the blank to the rotary chuck 2 and lock it, and the other end of the blank can be repeatedly processed without manual reinstallation, thereby improving the production efficiency of the equipment. The placement base 21 provided can place the blank for subsequent grasping, and the provided stop block 22 can contact the lower end surface of the blank to prevent the blank from being displaced when the connecting tube 23 grasps the blank, thereby affecting the subsequent process.
