[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a precision slide cylinder with automatic locking and unlocking, including a cylinder body 1 and a piston rod 3. The piston rod 3 is located inside the cylinder body 1. Compressed air enters the cylinder body 1, pushing the piston rod 3 to move. A slide groove 16 is provided at the top of the cylinder body 1. A connecting plate 6 is slidably connected inside the slide groove 16. The connecting plate 6 moves along the interior of the slide groove 16. A slide body 2 is fixedly connected to the top of the connecting plate 6. The slide body 2 moves, causing the connecting plate 6 to move as well. One end of the piston rod 3 is fixedly connected to the slide body 2. The piston rod 3 moves, causing the slide body 2 to move as well. A first locking hole 4 is provided on one side of the slide groove 16, and a second locking hole 5 is provided on the other side of the slide groove 16. A first locking block 7 is slidably connected to one end of the connecting plate 6, and a second locking block 5 is slidably connected to the other end of the slide groove 16. Hole 5 and the first locking block 7 are used together. The other end of the connecting plate 6 is slidably connected to the second locking block 8. The first locking hole 4 and the second locking block 8 are used together. The first locking block 7 and the second locking block 8 enter the second locking hole 5 and the first locking hole 4 respectively to lock the slide body 2. The first locking block 7 and the second locking block 8 are fixedly connected to one side of the iron plate 11. The iron plate 11 moves and moves the first locking block 7 and the second locking block 8. The connecting plate 6 is detachably connected to the electromagnet 13 between the first locking block 7 and the second locking block 8. When the electromagnet 13 is energized, it generates magnetic force. Under the attraction of the magnetic force, the iron plate 11 moves the first locking block 7 and the second locking block 8 towards the electromagnet 13, so that the first locking block 7 and the second locking block 8 are disengaged from the second locking hole 5 and the first locking hole 4 respectively.

[0022] Furthermore, the connecting plate 6 is symmetrically fixedly connected with a slide rod 9. The two ends of the first locking block 7 and the second locking block 8 are slidably connected to the slide rod 9. The first locking block 7 and the second locking block 8 move along the outside of the slide rod 9 to maintain the stability of the first locking block 7 and the second locking block 8 during movement. A spring 10 is provided on the outside of the slide rod 9. When the first locking block 7 and the second locking block 8 move, they squeeze the spring 10. The spring 10 generates elastic force when squeezed. When the spring 10 loses its squeezing force, under the action of the elastic force, the spring 10 carries the first locking block 7 and the second locking block 8 into the second locking hole 5 and the first locking hole 4 respectively.

[0023] Furthermore, a laser displacement sensor 17 is fixedly connected to one end of the cylinder body 1 to detect the moving distance of the slide body 2. A control panel 18 is fixedly connected to one side of the cylinder body 1. The electromagnet 13, the laser displacement sensor 17, and the cylinder body 1 are all electrically connected to the control panel 18 to better control the overall device.

[0024] Furthermore, the bottom of the connecting plate 6 is detachably connected to the fixing frame 12 by bolts, which facilitates the removal of the fixing frame 12 from the connecting plate 6, thereby allowing for the inspection or replacement of the buffer pad 15 or the electromagnet 13. The electromagnet 13 is detachably connected to the fixing frame 12 by bolts, which facilitates the replacement or inspection of the electromagnet 13.

[0025] Furthermore, buffer pads 15 are provided on both sides of the fixing frame 12, and a groove is provided at the bottom of the connecting plate 6. The buffer pads 15 move along the groove to one side of the first locking block 7 and the second locking block 8. After the electromagnet 13 is energized, the first locking block 7 and the second locking block 8 move towards the electromagnet 13 under the action of magnetic force, reducing the impact when the first locking block 7 and the second locking block 8 come into contact with the inner wall of the connecting plate 6.

[0026] Furthermore, both sides of the fixing frame 12 are provided with connecting grooves 14 that penetrate its surface, so as to prevent the thickness of the fixing frame 12 from affecting the magnetic force of the electromagnet 13 and to better attract the iron plate 11.

[0027] In use, when the slide body 2 needs to move, the electromagnet 13 is energized via the control panel 18. The magnetic force generated by the electromagnet 13 attracts the iron plate 11 to move in the direction of the electromagnet 13. The iron plate 11, carrying the first locking block 7 and the second locking block 8, overcomes the elastic force of the spring 10 and moves into the connecting plate 6, causing the first locking block 7 and the second locking block 8 to be pulled out from the second locking hole 5 and the first locking hole 4, respectively. One end of the first locking block 7 and the second locking block 8 contact the buffer pads 15 on both sides of the fixing frame 12. Through the buffering effect of the buffer pads 15, the impact of the first locking block 7 and the second locking block 8 is buffered, extending the first locking block 7... The lifespan of the second locking block 8 is used to unlock the slide body 2. At this time, compressed air is introduced into the cylinder 1 to push the piston rod 3 to move, thereby driving the slide body 2 with the connecting plate 6 to move along the slide groove 16. When the slide body 2 moves to the designated position, the laser displacement sensor 17 detects the position of the slide body 2 and feeds the position signal back to the control panel 18. The control panel 18 controls the electromagnet 13 to be de-energized, the iron plate 11 loses its magnetic attraction, and the elastic force of the spring 10 pushes the first locking block 7 and the second locking block 8 into the second locking hole 5 and the first locking hole 4 respectively, thereby locking the slide body 2.
