Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model. Embodiment 1

[0022] As shown in the attached Figures 1 to 4 A high-precision hanging cylinder with fast response, including a cylinder 1, a locking assembly 2 and an adjusting base 3. A locking assembly 2 is arranged above the cylinder 1. A connecting block 12 is arranged on one side of the cylinder 1 away from the locking assembly 2. Docking brackets 11 are arranged on both sides of the connecting block 12. The adjusting base 3 is arranged on the side of the docking bracket 11 away from the cylinder 1. The cylinder 1 includes a cylinder barrel 101, a piston 13, a piston seal ring 14, a wear-resistant ring 15 and a buffer sleeve 16. Pistons 13 are arranged on both sides of the inner wall of the cylinder barrel 101. A piston seal ring 14 is arranged at the center of the cylinder barrel 101 and the piston 13. A wear-resistant ring 15 is arranged on the side of the piston seal ring 14 away from the locking assembly 2. A buffer sleeve 16 is arranged on the side of the wear-resistant ring 15 away from the piston seal ring 14.

[0023] Among them: when the cylinder 1 is used again, when the piston 13 in the cylinder 1 moves, the moving position of the piston 13 inside the cylinder barrel 101 is detected by a displacement sensing probe 17, and the detected signal is detected by a human-machine interaction interface 10. Then, during the operation of the cylinder 1, when the piston 13 is reset, a force sensing probe 18 inside the buffer sleeve 16 detects the force exerted during each operation of the cylinder 1, so as to obtain detailed data during the operation of the cylinder 1. And when the cylinder 1 needs to adjust the output angle, at this time, the inclination angle of the cylinder 1 is adjusted through the adjusting base 3, so as to complete the adjustment of the cylinder 1, and high precision during the operation of the cylinder 1 is obtained through the displacement sensing probe 17 and the force sensing probe 18 connected to the human-machine interaction interface 10, so that the cylinder 1 can respond quickly. Embodiment 2

[0024] Based on Embodiment 1, the solution in Embodiment 1 will be further refined and introduced in combination with the following specific working methods, as shown in Figures 1 to 4 shown, see the following description for details:

[0025] As a preferred embodiment, the oil cylinder 1 further includes a displacement sensing probe 17, a force sensing probe 18, a buffer valve 19 and a sealing ring 20. A force sensing probe 18 is disposed on the side of the displacement sensing probe 17 away from the piston sealing ring 14. A buffer valve 19 is disposed on the side of the cylinder barrel 101 away from the piston 25. A sealing ring 20 is disposed at the center of the cylinder barrel 101 and the locking assembly 2. When the oil cylinder 1 is in use, the displacement sensing probe 17 and the force sensing probe 18 are respectively used to detect the movement of the piston 13 in the oil cylinder 1 and the pressure after reset, so as to complete the quick response during the operation of the oil cylinder 1. The oil cylinder 1 is buffered during the movement of the piston 13 through the cooperation of the buffer valve 19 and the buffer sleeve 16, so as to maintain and improve the stability of the oil cylinder 1 during use, thereby improving the safety of the oil cylinder 1 during use.

[0026] As a preferred embodiment, the adjustment base 3 includes a connecting plate 4, a rotating shaft 5 and a first gear 6. A rotating shaft 5 is disposed at the center of the two connecting plates 4. A first gear 6 is disposed on the side of the rotating shaft 5 away from the oil cylinder 1. When adjusting the oil cylinder 1 through the adjustment base 3, the first gear 6 is driven by a second gear 7. When the first gear 6 rotates, the first gear 6 drives the rotating shaft 5 to rotate, so that the docking bracket 11 connected to the rotating shaft 5 drives the oil cylinder 1 to rotate, thereby maintaining the angle adjustment of the oil cylinder 1. A bearing is installed at the connection between the connecting plate 4 and the rotating shaft 5 to reduce the friction of the rotating shaft 5.

[0027] As a preferred embodiment, the adjustment base 3 further includes a second gear 7, a speed reducer 8, a servo motor 9 and a human-machine interface 10. The second gear 7 is disposed on the side away from the connecting plate 4 with a speed reducer 8. The speed reducer 8 is disposed on the side away from the second gear 7 with a servo motor 9. The servo motor 9 is disposed on the side away from the speed reducer 8 with a human-machine interface 10. The first gear 6 and the second gear 7 are meshed with each other. The oil cylinder 1 forms a rotating structure between the connecting block 12, the docking bracket 11 and the adjustment base 3. The servo motor 9 is equipped with an electromagnetic brake. When the servo motor 9 receives a stop command and cuts off the current, the electromagnetic brake is activated, generating a magnetic force to attract the iron core inside the brake, thereby generating a frictional force to lock the motor shaft and prevent the shaft from rotating. When the servo motor 9 rotates, the servo motor 9 rotates in cooperation with the speed reducer 8, thereby driving the second gear 7 to rotate. A connecting block 12 is installed at the bottom of the oil cylinder 1, and the connecting block 12 is restricted by the docking bracket 11. Then the servo motor 9 drives the connecting block 12 through the rotating shaft 5, so that the oil cylinder 1 installed on the connecting block 12 rotates.

[0028] As a preferred embodiment, the locking assembly 2 includes a locking bracket 21, a fixed bracket 24, a limiting block 2401, a spring 25 and a deceleration bracket 26. A fixed bracket 24 is arranged above the inner wall of the locking bracket 21. Limiting blocks 2401 are arranged on both sides of the fixed bracket 24. A spring 25 is arranged on the side of the fixed bracket 24 away from the first gear 6. A deceleration bracket 26 is arranged on the side of the spring 25 away from the fixed bracket 24. When the oil cylinder 1 fails, the locking assembly 2 receives a signal transmitted by the human-machine interface 10 at this time, causing the motor 23 to rotate and the motor 23 to squeeze the rod body inside the limiting bracket 22, causing the spring 25 that is tightened in the rod body in contact with the limiting block 2401 to be pulled away from the reset position, so that the restriction of the limiting block 2401 is released. Then the spring 25 inside the locking bracket 21 can be reset. Then the locking bracket 21 drives the fixed bracket 24 and the deceleration bracket 26 to fit with the piston 13. Then when the fixed bracket 24 receives the downward impact force of the piston 13, since the fixed bracket 24 is composed of two groups of rod bodies and a rotating shaft, when the deceleration bracket 26 receives the downward pressure of the piston 13, the angle of the fixed bracket 24 changes to increase the contact area between the fixed bracket 24 and the locking bracket 21, so that the deceleration bracket 26 buffers the reset after the failure of the piston 13, thereby protecting the operation of the oil cylinder 1.

[0029] As a preferred embodiment, the locking assembly 2 further includes a limiting bracket 22 and a motor 23, and a motor 23 is arranged at the centers of the limiting bracket 22 and the piston 13.

[0030] The working process of the present utility model is as follows: When the oil cylinder 1 is in use, the displacement sensing probe 17 and the force sensing probe 18 are respectively used to detect the movement of the piston 13 in the oil cylinder 1 and the pressure after reset, so as to complete the rapid response during the operation of the oil cylinder 1. And the oil cylinder 1 is buffered during the movement of the piston 13 through the buffer valve 19 and the buffer sleeve 16, so as to maintain and improve the stability of the oil cylinder 1 during use, thereby improving the safety of the oil cylinder 1 during use. Then, when adjusting the oil cylinder 1 through the adjusting base 3, the first gear 6 is driven by the second gear 7. When the first gear 6 rotates, the first gear 6 drives the rotating shaft 5 to rotate, so that the docking bracket 11 connected to the rotating shaft 5 drives the oil cylinder 1 to rotate, thereby maintaining the adjustment of the angle of the oil cylinder 1. A bearing is installed at the connection between the connecting plate 4 and the rotating shaft 5 to reduce the friction of the rotating shaft 5. And the servo motor 9 is equipped with an electromagnetic brake. When the servo motor 9 receives a stop command and the current is cut off, the electromagnetic brake is activated, generating a magnetic force to attract the iron core inside the brake, thereby generating a frictional force to lock the motor shaft and prevent the shaft from rotating. When the servo motor 9 rotates, the servo motor 9 rotates in cooperation with the speed reducer 8, thereby driving the second gear 7 to rotate. And a connecting block 12 is installed at the bottom of the oil cylinder 1, and the connecting block 12 is restricted by the docking bracket 11;

[0031] Then the servo motor 9 drives the connecting block 12 through the rotating shaft 5, so that the oil cylinder 1 installed on the connecting block 12 rotates. When the oil cylinder 1 fails, the locking assembly 2 receives the signal transmitted by the human-machine interface 10, causing the motor 23 to rotate, and the motor 23 squeezes the rod body inside the limit bracket 22, so that the spring 25 tensioned in the rod body contacting the limit block 2401 is separated from the reset position, releasing the restriction of the limit block 2401. Then the spring 25 inside the locking bracket 21 can be reset, and then the locking bracket 21 drives the fixed bracket 24 to fit the deceleration bracket 26 with the piston 13. Then, when the fixed bracket 24 receives the downward impact force of the piston 13, since the fixed bracket 24 is composed of two groups of rod bodies and a rotating shaft, when the deceleration bracket 26 receives the downward pressure of the piston 13, the angle of the fixed bracket 24 changes to increase the contact area between the fixed bracket 24 and the locking bracket 21, so that the deceleration bracket 26 buffers the reset after the failure of the piston 13, thereby protecting the operation of the oil cylinder 1. The above is the working principle of the high-precision hanging bin oil cylinder with fast response.
