Description

Technical Field

[0002] An electric cylinder is an actuator that converts the rotary motion of an electric motor into linear motion. It has advantages such as compact structure, high control precision, and fast response speed, and is widely used in automation equipment, robots, medical devices and other fields.

[0003] Traditional electric cylinders typically use lead screws and nuts or timing belts to convert the rotary motion of a motor into linear motion. However, in practical applications, due to factors such as load eccentricity and installation errors, the piston rod of the electric cylinder is prone to rotation, leading to the following problems:

[0004] 1. Affects motion accuracy: The rotation of the piston rod will cause the load to deflect, affecting the accuracy of linear motion and even causing equipment failure;

[0005] 2. Shortened service life: The rotation of the piston rod will accelerate the wear of the guide components and seals, thus shortening the service life of the electric cylinder;

[0006] 3. Safety hazards exist: In some application scenarios, the rotation of the piston rod may cause the equipment to go out of control, posing a safety hazard. Utility Model Content

[0023] The following drawings will disclose several embodiments of this utility model. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these physical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0024] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0025] This embodiment provides an electric cylinder with anti-rotation function. The electric cylinder can effectively prevent the piston rod 13 from rotating during the movement, thereby preventing the load from deflecting, improving the movement accuracy, and also effectively preventing wear of the electric cylinder's seals, thus increasing the service life of the electric cylinder. Furthermore, preventing the piston rod 13 from rotating can effectively prevent equipment from going out of control, thereby reducing equipment safety hazards.

[0026] Combination Figures 1 to 3 As shown, the electric cylinder with anti-rotation function in this embodiment includes an electric cylinder body 10 and an anti-rotation part 20. The electric cylinder body 10 includes a driver 11, a cylinder body 12 and a piston rod 13. The driver 11 drives the piston rod 13. The piston rod 13 is installed in the cylinder body 12 and moves along the length of the cylinder body 12. The anti-rotation part 20 can perform anti-rotation treatment on the piston rod 13 to prevent the piston rod 13 from rotating during the movement, thereby realizing the high-precision use of the electric cylinder.

[0027] In this embodiment, the driver 11 is a motor, and the driver 11 drives the piston rod 13 through a transmission structure (not shown in the figure). The transmission structure in this embodiment is a transmission belt. Under the transmission action of the transmission belt, the piston rod 13 moves linearly back and forth along the length of the cylinder 12.

[0028] Combination Figure 1 and Figure 2As shown, the anti-rotation part 20 of this embodiment includes a mounting block 21, a guide shaft 22, and an anti-rotation block 23. The mounting block 21 is located at the end of the cylinder body 12, and the end of the guide shaft 22 is connected to the end of the piston rod 13 through the anti-rotation block 23. In this embodiment, the mounting block 21 is fixedly installed at the end of the cylinder body 12. The piston rod 13 and the guide shaft 22 are both arranged through the mounting block 21. One end of the anti-rotation block 23 is fixedly connected to the end of the piston rod 13, and the other end is fixedly connected to the end of the guide shaft 22. When the piston rod 13 performs linear reciprocating motion, the guide shaft 22 moves synchronously under the connection of the anti-rotation block 23. Since the mounting block 21 is fixedly set, the piston rod 13 is connected to the guide shaft 22 in conjunction with the anti-rotation block 23. When the piston rod 13 moves, the guide shaft 22 can guide its movement and play an anti-rotation role, preventing the piston rod 13 from rotating during the movement.

[0029] In this embodiment, the mounting block 21 is provided with a first through hole 211 and a second through hole 212. The first through hole 211 corresponds to the position of the piston rod 13 so that the piston rod 13 passes through the mounting block 21. The second through hole 212 corresponds to the position of the guide shaft 22 so that the guide shaft 22 passes through the mounting block 21. The first through hole 211 allows the piston rod 13 to pass stably through the mounting block 21, and the second through hole 212 allows the guide shaft 22 to pass stably through the mounting block 21, so that the guide shaft 22 can effectively cooperate with the piston rod 13 to guide the piston rod 13 and prevent it from rotating.

[0030] Furthermore, in this embodiment, a guide sleeve 30 is provided on the mounting block 21. The guide sleeve 30 cooperates with the guide shaft 22 to guide the movement of the guide shaft 22. The guide sleeve 30 is provided on the mounting block 21 to stably install and guide the guide shaft 22.

[0031] In this embodiment, the electric cylinder with anti-rotation function is used in practical applications. The mounting block 21 is fixedly installed at the end of the cylinder body 12, and the anti-rotation block 23 connects the end of the piston rod 13 to the end of the guide shaft 22. When the piston rod 13 performs linear reciprocating motion, the guide shaft 22 moves synchronously under the connection of the anti-rotation block 23, so that the piston rod 13 and the guide shaft 22 pass through the mounting block 21 synchronously. Under the cooperation of the mounting block 21 and the anti-rotation block 23, the guide shaft 22 guides the piston rod 13 and plays an anti-rotation role, effectively preventing the piston rod 13 from rotating during the movement, thereby preventing the load on the electric cylinder from deflecting, improving the movement accuracy, and also effectively preventing wear on the seals of the electric cylinder, increasing the service life of the electric cylinder. Furthermore, the anti-rotation of the piston rod 13 can effectively prevent equipment loss of control, thereby reducing equipment safety hazards.
