[0002] In the process of modern industrial automation, cylinders, as core actuators, are deeply integrated into fields such as machinery manufacturing, automobile production, food packaging, and electronic assembly due to their ability to convert compressed air pressure energy into mechanical energy and achieve linear reciprocating or oscillating motion. Whether it is the precision assembly of automobile parts, the fine processing of electronic products, or the automated production line of food packaging, cylinders are the key to ensuring the smooth operation of the production process. However, as industrial production accelerates towards high precision, high efficiency, and flexibility, higher requirements are placed on cylinder performance. Traditional cylinders have fixed stroke and thrust, making it difficult to adapt to complex and ever-changing working conditions. Whenever production tasks are adjusted, cylinders need to be replaced frequently, which not only significantly increases costs but also prolongs downtime, becoming a bottleneck restricting the improvement of production efficiency. In addition, some cylinders are inconvenient to adjust, and although some have adjustment structures, the operation is complicated and the adjustment accuracy is low, making it impossible to quickly and accurately match the production rhythm.

[0024] Please see Figure 1-4 This utility model provides a technical solution:
[0025] A cylinder with an adjustable structure includes a base plate 1. A rectangular sliding opening 2 is formed on the upper left side of the base plate 1. A limit guide rod 3 is fixedly connected to the middle of the inner front wall and the middle of the inner rear wall of the rectangular sliding opening 2. An adjustment fixing frame 4 is fixedly connected to the upper right side of the base plate 1. An operation key 5 is fixedly connected to the upper front end of the adjustment fixing frame 4. A cylinder adjustment device 6 is fixedly connected to the middle front end of the adjustment fixing frame 4. The lower end of the cylinder adjustment device 6 is located inside the rectangular sliding opening 2 and is movably connected to the limit guide rod 3.
[0026] In this embodiment, the cylinder adjustment device 6 includes a servo motor 61, which is fixedly connected to the front end of the adjustment bracket 4. The output end of the servo motor 61 passes through the middle of the front end of the adjustment bracket 4 and is fixedly connected to a screw rod 62. The rear end of the screw rod 62 is movably connected to the adjustment bracket 4 through a bearing. A reinforcing clamping plate frame 63 is threadedly movably connected to the front of the outer surface of the screw rod 62. A long bolt 64 is threadedly movably connected to the left rear end of the reinforcing clamping plate frame 63. A cylinder adjustment structure 65 is clamped to the inner right wall of the reinforcing clamping plate frame 63.
[0027] Through the above solution: the servo motor 61 drives the screw rod 62 to rotate, which in turn moves the reinforced clamping plate frame 63 axially, achieving precise adjustment of the position of the cylinder adjustment structure 65. The long bolt 64 firmly locks the cylinder adjustment structure 65 into the reinforced clamping plate frame 63 to ensure stability. Through the precise control of the servo motor 61, the cylinder stroke and thrust can be adjusted in real time, adapting to different working conditions without replacing the cylinder. The modular design means that maintenance only requires replacing the corresponding components, reducing downtime. Compared with the traditional method, this device significantly reduces equipment costs and downtime losses, improves production flexibility and efficiency, and becomes a key solution to solve production bottlenecks.
[0028] In this embodiment, the cylinder adjustment structure 65 includes a cylinder body 651, a piston rod 652 is disposed inside the cylinder body 651, a front locking nut 653 and a rear locking nut 654 are respectively threadedly connected to the front and rear parts of the outer surface of the piston rod 652, the front of the outer surface of the cylinder body 651 is threadedly connected to an adjusting nut stroke assembly 655, the adjusting nut stroke assembly 655 is located in front of the front locking nut 653, a reinforcing connecting plate 656 is fixedly connected to the front right end of the cylinder body 651, and limit sliders 657 are fixedly connected to the front and rear lower ends of the cylinder body 651. The two limit sliders 657 are slidably connected within the rectangular sliding opening 2, the lower end surface of the cylinder body 651 is in close contact with but not fixed to the upper end surface of the base plate 1, the cylinder body 651... 1. Two limiting sliders 657 are interlocked with the limiting guide rod 3. The cylinder body 651 is snapped into the reinforcing plate frame 63 by the reinforcing connecting plate 656. The reinforcing connecting plate 656 is detachably connected to the reinforcing plate frame 63 by the long bolt 64. The adjusting nut stroke assembly 655 includes a stroke adjusting nut column 6551. The rear end of the stroke adjusting nut column 6551 is fixedly connected to a turning block 6552. Several anti-slip convex strips 6553 are fixedly connected in a ring array on the outer surface of the turning block 6552. The front end of the stroke adjusting nut column 6551 is fixedly connected to an anti-collision pad 6554. The turning block 6552, the stroke adjusting nut column 6551 and the anti-collision pad 6554 are threadedly connected to the front of the outer surface of the piston rod 652.
[0029] The above scheme involves rotating the turning block 6552 of the adjusting nut stroke assembly 655, which, through its threaded connection with the piston rod 652, drives the stroke adjusting nut column 6551 to move back and forth, thereby precisely controlling the extension length of the piston rod 652 and achieving fine-tuning of the stroke. The front locking nut 653 and the rear locking nut 654 can fix the position of the piston rod 652 to prevent loosening. The cylinder body 651, through the limit slider 657, cooperates with the rectangular slide 2 and the limit guide rod 3 to ensure the stability and accuracy of movement. The detachable connection of the reinforcing connecting plate 656, the long bolt 64, and the reinforcing clamp frame seat 63 facilitates overall disassembly and maintenance. This structure is easy to operate, has high adjustment accuracy, can quickly adapt to the production rhythm, and significantly improves production efficiency and equipment practicality.
[0030] It should be noted that this utility model is a cylinder with an adjustable structure. During use, firstly, when the cylinder needs adjustment, press operation key 5 to start the servo motor 61. The servo motor 61 drives the screw rod 62 to rotate. Since the screw rod 62 is threadedly connected to the reinforcing plate frame 63, the reinforcing plate frame 63 moves back and forth along the screw rod 62, thereby moving the cylinder body 651, which is engaged with the reinforcing plate frame 63, achieving initial adjustment of the cylinder stroke. The cylinder body 651 slides within the rectangular sliding opening 2 and along the limiting guide rod 3 via the lower limiting slider 657, ensuring the stability and guidance of the movement. For more precise adjustment, the cylinder body 651 can be rotated... The rotating block 6552 of the adjustable nut stroke assembly 655 drives the stroke adjusting nut column 6551 to move on the piston rod 652, controlling the extension length of the piston rod 652. The front locking nut 653 and the rear locking nut 654 can fix the position of the piston rod 652. Therefore, the stroke is initially adjusted by components such as the servo motor 61, screw rod 62, and reinforced card plate frame seat 63. Precise fine-tuning is performed by combining the adjustable nut stroke assembly 655. The limit slider 657 and the limit guide rod 3 ensure stable operation. This effectively solves the problems of poor adaptability and inconvenient adjustment of traditional cylinders. It can quickly and accurately adapt to different working conditions, improve production efficiency, and reduce equipment replacement costs.
