[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Refer to Figures 1-6, A grasping structure for feeding in the production of a traction wheel, including a base 1. A chamber 2 is provided inside the base 1. A servo motor 3 is fixedly installed on the bottom of the chamber 2. The upper end of the drive shaft of the servo motor 3 is fixedly connected to a rotating rod 4. The upper end of the rotating rod 4 vertically rotates through the top surface at the central position of the chamber 2. The upper end of the rotating rod 4 is fixedly connected to a rotating table 5. The servo motor 3 drives the rotating rod 4 and the rotating table 5 to rotate, and enables the rotating table 5 to rotate smoothly under the limiting action of the pulley 11 and the annular limiting groove 13. Two pulleys 11 are fixedly installed at the lower end of the rotating table 5 away from the rotating rod 4. The upper end of the base 1 is fixedly connected to an annular seat 12. An annular limiting groove 13 is provided at the upper end of the annular seat 12. Both pulleys 11 are inserted into the annular limiting groove 13 and roll and abut against each other. When the pulley 11 moves in the annular limiting groove 13, it can provide stable support for the rotation of the rotating table 5. A first cylinder 6 is fixedly installed at the upper end of the rotating table 5. The free end of the piston rod of the first cylinder 6 is fixedly connected to a mounting block 7. A U-shaped seat 8 is fixedly connected to the mounting block 7. The first cylinder 6 cooperates with the U-shaped seat 8 and the U-shaped bracket 10 to drive the clamping mechanism to move horizontally. A second cylinder 9 is fixedly installed inside the U-shaped seat 8. The open end of the U-shaped seat 8 is vertically upward. The mounting block 7 and the U-shaped seat 8 are fixedly connected by a number of bolts. The second cylinder 9 is fixedly installed on the bottom of the open end of the U-shaped seat 8 away from the mounting block 7. The second cylinder 9 cooperates with the U-shaped bracket 10 to drive the clamping mechanism to move vertically, facilitating the adjustment of the grasping operation angle and position according to actual needs and improving production efficiency.

[0025] The piston rod of the second cylinder 9 vertically penetrates through the U-shaped seat 8. A U-shaped bracket 10 is fixedly connected to the lower end of the piston rod of the second cylinder 9. A grasping mechanism is arranged inside the U-shaped bracket 10. The grasping mechanism includes hydraulic cylinders 14 respectively fixedly installed on the side walls of the vertical sections on both sides of the U-shaped bracket 10. The piston rods of the two hydraulic cylinders 14 respectively horizontally penetrate through the side walls of the vertical sections on both sides of the U-shaped bracket 10. Clamping blocks 15 are fixedly connected to the opposite side walls of the piston rods of the two hydraulic cylinders 14. When the two hydraulic cylinders 14 on the U-shaped bracket 10 are started, the two hydraulic cylinders 14 drive the two clamping blocks 15 to move horizontally towards each other until the traction wheels are respectively inserted into the circular slots 16 on the two clamping blocks 15. Circular slots 16 are arranged on the opposite side walls of the two clamping blocks 15 near the lower end. Through grooves 17 are arranged inside the two clamping blocks 15. The two through grooves 17 are arranged near the upper end of the clamping blocks 15. Two springs 18 are fixedly installed on the top surfaces of the two through grooves 17. The lower ends of the two springs 18 on the same side are fixedly connected to T-shaped rods 19. The lower ends of the vertical sections of the two T-shaped rods 19 respectively penetrate through the bottoms of the two through grooves 17. Arc-shaped abutting blocks 20 are fixedly connected to the lower ends of the two T-shaped rods 19 located inside the circular slots 16. The traction wheels inserted into the circular slots 16 are abutted and pressed against the arc-shaped abutting blocks 20, so that the arc-shaped abutting blocks 20 drive the T-shaped rods 19 to compress the springs 18 inside the through grooves 17 under force. At the same time, after the electromagnet 21 is powered on, it is attracted and positioned with the traction wheel, so as to effectively clamp and position the traction wheel in the circular slot 16. During unloading, only need to cut off the power supply of the electromagnet 21, and then start the two hydraulic cylinders 14 to drive the two clamping blocks 15 to separate horizontally until the traction wheel disengages from the circular slot 16, which is convenient and fast to position the traction wheel. The structure is simple and practical. The arc-shaped abutting block 20 is made of rubber. An electromagnet 21 is embedded in the arc-shaped inner wall at the center position of the arc-shaped abutting block 20. The side wall of the electromagnet 21 is seamlessly connected with the arc-shaped inner wall of the arc-shaped abutting block 20. The electromagnet 21 is used to position the traction wheel in the circular slot 16.

[0026] When the utility model is in use, the servo motor 3 in the chamber 2 on the base 1 is started, so that the servo motor 3 drives the rotating rod 4 and the rotating table 5 to rotate, and the rotating table 5 rotates smoothly under the limiting action of the pulley 11 and the annular limiting groove 13. At this time, the rotating table 5 cooperates with the first cylinder 6, the U-shaped seat 8 and the U-shaped bracket 10 to drive the clamping mechanism to rotate smoothly. At the same time, the first cylinder 6 cooperates with the U-shaped seat 8 and the U-shaped bracket 10 to drive the clamping mechanism to move horizontally, and the second cylinder 9 cooperates with the U-shaped bracket 10 to drive the clamping mechanism to rise and fall vertically, so as to adjust the grasping operation angle and position according to actual needs and improve production efficiency. When the two clamping blocks 15 move to the side of the traction wheel, the traction wheel is placed opposite to the two clamping blocks 15. Start the two hydraulic cylinders 14 on the U-shaped bracket 10, so that the two hydraulic cylinders 14 drive the two clamping blocks 15 to move horizontally relative to each other until the traction wheels are respectively inserted into the circular slots 16 on the two clamping blocks 15. At this time, the traction wheel and the arc-shaped abutment block 20 are pressed against each other, so that the arc-shaped abutment block 20 is forced to drive the T-bar 19 to compress the spring 18 in the through groove 17. At the same time, the electromagnet 21 is energized and attracted to the traction wheel for positioning, thereby effectively clamping and positioning the traction wheel in the circular slot 16. When unloading, it is only necessary to cut off the power to the electromagnet 21, start the two hydraulic cylinders 14 to drive the two clamping blocks 15 to separate horizontally until the traction wheel is detached from the circular slot 16, so that the traction wheel can be positioned quickly and conveniently, and the structure is simple and practical.
