[0022] Such as Figure 1 、 Figure 2As shown in the figure, an integrated oil and gas rotary chuck includes a chassis 1. A chuck body 2 is fixedly connected to the right side surface of the chassis 1. A lower cylinder 3 and an upper cylinder 4 are sleeved on the surface of the chuck body 2. A first through hole A is formed on the surface of the lower cylinder 3, and a second through hole B is formed on the surface of the upper cylinder 4. A piston 5 is arranged at the end of the first through hole A. A thrust ball bearing 18 is attached to the right side of the piston 5. A sliding sleeve 6 is attached to the right side of the thrust ball bearing 18, and the sliding sleeve 6 is slidably connected to the chuck body 2. A dust-proof ring 7 is clamped between the upper cylinder 4 and the sliding sleeve 6. A retaining ring 8 is fixedly installed between the chassis 1 and the lower cylinder 3. A deep groove ball bearing 19 is fixedly sleeved on the surface of the chuck body 2. A fastening assembly is arranged between the deep groove ball bearing 19 and the sliding sleeve 6. A ball roller 17 is sleeved on the surface of the dust-proof ring 7. A clamping portion is arranged at the right end of the chuck body 2. More specifically, when oil or gas enters from the first through hole A, the oil or gas pushes the piston 5 to move to the right. The piston 5 pushes the thrust ball bearing 18 to move to the right. The moving ring of the thrust ball bearing 18 drives the sliding sleeve 6. After the sliding sleeve 6 is converted by a taper, it drives the collet 20 to radially contract, and the jaws 21 on the collet 20 clamp the workpiece. The upper cylinder 4 is fixed from moving to the right through the intermediate deep groove ball bearing 19, and the rotation will not cause the rotation to jam. The specific actions are as follows. When oil / gas enters from the second through hole B, it drives the piston 5 to move to the left. The piston 5 pulls the dust-proof ring 7 to move to the left. Then, through the ball roller 17 on the dust-proof ring 7, the end face of the sliding sleeve 6 is pushed, so that the sliding sleeve 6 also moves to the left. Since the collet 20 is fixed on the chassis 1, the collet 20 will not move to the left, so that the collet 20 and the sliding sleeve 6 are forced to separate. Under the action of its own elastic force, the collet 20 can achieve the purpose of forcibly loosening the workpiece, and then the continuous opening and clamping work can be realized to achieve automated production.

[0023] The fastening assembly includes a first nut 9 and a second nut 10. A bolt is threadedly connected to the surface of the deep groove ball bearing 19, and the bolt is threadedly connected to both the first nut 9 and the second nut 10. It should be noted that the bolt, the first nut 9, and the second nut 10 are used in cooperation to install and fix the deep groove ball bearing 19.

[0024] A flange is arranged on the surface of the sliding sleeve 6, and the flange is attached to the surface of the ball roller 17. More specifically, by arranging the flange, the ball roller 17 can effectively contact the sliding sleeve 6 during the moving process, so as to push the sliding sleeve 6 to move.

[0025] The clamping portion includes a collet 20. A plurality of jaws 21 are slidably connected to the inner wall of the collet 20, and the left ends of the jaws 21 are fixedly connected to the chassis 1. It should be noted that when the sliding sleeve 6 pushes the collet 20 to move, the jaws 21 will be squeezed, so as to use the jaws 21 for clamping and fixing. When the sliding sleeve 6 retracts, it drives the collet 20 to reset, so as to relieve the extrusion of the jaws 21, and the jaws 21 will lose the clamping function.

[0026] A second oil seal 12, a fifth oil seal 15 and a sixth oil seal 16 are arranged between the upper cylinder block 4 and the dust-proof ring 7, and a fourth oil seal 14 is arranged between the lower cylinder block 3 and the dust-proof ring 7. More specifically, by arranging the second oil seal 12, the fifth oil seal 15 and the sixth oil seal 16, the contact surface between the upper cylinder block 4 and the dust-proof ring 7 is sealed.

[0027] A third oil seal 13 is arranged between the chuck body 2 and the sliding sleeve 6, and a first oil seal 11 is arranged between the lower cylinder block 3 and the upper cylinder block 4. It should be noted that the third oil seal 13 is used to enhance the sealing performance between the chuck body 2 and the sliding sleeve 6, and the first oil seal 11 is arranged to seal the gap between the lower cylinder block 3 and the upper cylinder block 4.

[0028] In summary: When oil or gas enters from the first through hole A, the oil or gas pushes the piston 5 to move to the right. The piston 5 pushes the thrust ball bearing 18 to move to the right. The moving ring of the thrust ball bearing 18 drives the sliding sleeve 6. After the taper conversion, the sliding sleeve 6 drives the spring collet 20 to contract radially, and the jaws 21 on the spring collet 20 clamp the workpiece. The upper cylinder block 4 is fixed by the intermediate deep groove ball bearing 19 and does not move to the right, and rotation will not cause rotation jamming. The specific operation is as follows. When oil / gas enters from the second through hole B, it drives the piston 5 to move to the left. The piston 5 pulls the dust-proof ring 7 to move to the left. Then, through the ball roller 17 on the dust-proof ring 7, the end face of the sliding sleeve 6 is pushed, so that the sliding sleeve 6 also moves to the left. Since the spring collet 20 is fixed on the chassis 1, the spring collet 20 will not move to the left, so that the spring collet 20 and the sliding sleeve 6 are forced to separate. Under the action of its own elastic force, the spring collet 20 can achieve the purpose of forcibly loosening the workpiece, and then the continuous opening and clamping operation can realize automated production, avoiding the situation where the existing chuck may not be able to be loosened.
