[0030] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0031] like Figures 1 to 4 As shown, the multi-combination precise positioning device includes a fixed plate 1 and a movable plate 15. An A telescope 2 is provided on the fixed plate 1. The A telescope 2 reciprocates the A positioning module along the X direction. The A positioning module has a plurality of A limit columns 5. The end positions of different A limit columns 5 extended along the Y direction are different. A B telescope 16 is provided on the movable plate 15. The B telescope 16 reciprocates the B positioning module along the X direction. The B positioning module has a plurality of B limit columns 19. The end positions of different B limit columns 19 extended along the Y direction are different. The movable plate 15 approaches the fixed plate 1 along the Y direction, so that any B limit column 19 docks with any A limit column 5 to form a stop positioning.

[0032] The A telescopic device 2 and the B telescopic device 16 can be any one of a pneumatic cylinder, a hydraulic cylinder, and an electric push rod. The above telescopic devices all have a telescopic shaft that can drive the positioning module to perform horizontal displacement.

[0033] like Figures 1 to 4As shown, the telescopic axis of the A telescope 2 is fixedly connected to the A base 4 of the A positioning module through the A support rod 3. At least two A limit columns 5 are arranged on the outer side of the A base 4, and the A limit columns 5 are arranged along the Y direction; the A telescope 2 drives the telescopic axis to extend or shorten, and synchronously drives the A base 4 to move back and forth along the X direction through the A support rod 3, so that the A limit columns 5 on the A base 4 also move synchronously.

[0034] An assembly block 6 is provided on the top surface of base A 4. This assembly block 6 has at least two threaded holes defined along the Y-axis. These holes threadably engage adjustment rods 7, which are positioned one above and one below the A-limiting posts 5. The threaded engagement of the adjustment rods 7 allows their extension along the Y-axis to be adjusted independently by turning them, thereby adapting to varying positioning constraints.

[0035] A guide rail 8 is provided on the fixed plate 1 along the X direction, and a slider 9 is provided at the bottom of the A base 4. The slider 9 is engaged with the guide rail 8 to form a guide-sliding connection; Figure 5 As shown, an A left limit switch 10 and an A right limit switch 11 are provided on the fixed plate 1 at both ends of the A guide rail 8 in a one-to-one correspondence, and an A limit block 12 is provided at the bottom of the A base 4 in a corresponding manner, and the A limit block 12 is located between the A left limit switch 10 and the A right limit switch 11.

[0036] The A telescopic device 2 drives the A base 4 to slide along the A guide rail 8, providing guidance and stability for the sliding process; it simultaneously drives the A limit block 12 to move back and forth. When the A limit block 12 contacts the A left limit switch 10, the A telescopic device 2 stops. When the A limit block 12 contacts the A right limit switch 11, the A telescopic device 2 stops. The moving range of the A base 4 is determined by the left and right limit switches.

[0037] A buffer 13 is provided on both sides of the fixed plate 1, and an A buffer plate 14 is provided at the bottom of the A base 4. A buffer end protrudes from both sides of the A buffer plate 14, which press against the A buffer 13 to form a buffering resistance. When the B limit post 19 on the movable plate 15 and the A limit post 5 on the fixed plate 1 are docked and collided, the A buffer end on one side of the A buffer plate 14 presses against the A buffer 13, thereby providing a damping force through the A buffer 13 to absorb the impact force, ensure smooth docking, and prevent damage caused by the collision.

[0038] like Figures 1 to 4 As shown, the telescopic axis of the B telescope 16 is fixedly connected to the B base 18 of the B positioning module through the B support rod 17. At least two B limit columns 19 are arranged on the outer side of the B base 18, and the B limit columns 19 are arranged along the Y direction; the B telescope 16 drives the telescopic axis to extend or shorten, and synchronously drives the B base 18 to move back and forth along the X direction through the B support rod 17, so that the B limit columns 19 on the B base 18 also move synchronously.

[0039] An adjustment block 20 is provided on the top surface of the B base 18 corresponding to each B limit column 19. A Y adjustment slot is provided on the adjustment block 20. At least two locking holes are provided on the top surface of the B base 18 in communication with the Y adjustment slot. Screws 21 are sequentially passed through the adjustment slot and the locking hole to form a locking fixation. Loosening the screw 21 releases the adjustment block 20, allowing the adjustment block 20 to freely extend and retract along the Y direction within the length range of the Y adjustment slot. After the adjustment block 20 is extended and retracted to the desired length, the screw 21 is tightened to fix the position of the adjustment block 20, thereby adjusting the extension position of the outer end of the adjustment block 20. When any B limit column 19 is docked with any A limit column 5, the corresponding adjustment block 20 and the adjustment rod 7 are opposed to or even docked with each other, thereby achieving top pressure restriction on the B limit column 19 and the A limit column 5 to avoid excessive collision between the two.

[0040] The outer sides of base A 4 and base B 18 are provided with multiple steps, each with different Y-positioned surfaces. Each step surface is provided with a limit post A 5 and a limit post B 19. The multiple steps create a wide Y-distance difference, thereby expanding the positioning range of the limit posts and improving adjustment flexibility.

[0041] A B guide rail 22 is provided on the movable plate 15 along the X direction, and a B slider 23 is provided at the bottom of the B base 18. The B slider 23 engages with the B guide rail 22 to form a guide-sliding connection; Figure 5 As shown, a B left limit switch 24 and a B right limit switch 25 are correspondingly provided at both ends of the B guide rail 22 on the movable plate 15, and a B limit block 26 is correspondingly provided at the bottom of the B base 18, and the B limit block 26 is located between the B left limit switch 24 and the B right limit switch 25.

[0042] The B telescope 16 drives the B base 18 to slide along the B guide rail 22, providing guidance and stability during the sliding process; it simultaneously drives the B limit block 26 to move back and forth. When the B limit block 26 contacts the B left limit switch 24, the B telescope 16 stops. When the B limit block 26 contacts the B right limit switch 25, the B telescope 16 stops. The moving range of the B base 18 is determined by the left and right limit switches.

[0043] B buffers 27 are provided on both sides of the movable plate 15, and a B buffer plate 28 is provided at the bottom of the B base 18. B buffer ends protrude from both sides of the B buffer plate 28, which press against the B buffers 27 to provide a buffering resistance. When the B limit posts 19 on the movable plate 15 collide with the A limit posts 5 on the fixed plate 1, causing an impact, the B buffer ends on one side of the B buffer plate 28 press against the B buffer 27, thereby providing a damping force through the B buffer 27 to absorb the impact force, ensuring a smooth docking while preventing damage caused by the impact.

[0044] The fixed plate 1 is mounted on the fixed side of the telescopic actuator, while the movable plate 15 is mounted on the movable side. The movable side drives the movable plate 15 toward or away from the fixed plate 1 on the fixed side. The telescopic actuator is specifically a pneumatic cylinder, with the cylinder body representing the fixed side and the piston rod representing the movable side. The cylinder drives the piston rod to retract, pulling the movable plate 15 toward the fixed plate 1, causing the two limit posts on either side to collide and limit the cylinder. The displacement of the two telescoping devices allows for the collision of different limit posts, enabling precise positioning of the cylinder at different locations.

[0045] How this multi-combination precise positioning device works:

[0046] 1. The A telescopic device 2 drives the telescopic shaft to extend or shorten, and synchronously drives the A base 4 to move back and forth along the X direction through the A support rod 3, so that the A limit column 5 on the A base 4 also moves synchronously.

[0047] 2. The B telescopic device 16 drives the telescopic shaft to extend or shorten, and synchronously drives the B base 18 to move back and forth along the X direction through the B support rod 17, so that the B limit column 19 on the B base 18 also moves synchronously.

[0048] 3. The cylinder drives the piston rod to retract, pulling the movable plate 15 close to the fixed plate 1, so that the adjusted B limit column 19 collides with the A limit column 5, achieving the precise positioning of the currently used cylinder.
