DETAILED DESCRIPTION

[0022] The utility model will be further described below in connection with the drawings and embodiment.

[0023] Please combine with reference to Figure 1 , Figure 2 And Figure 3 Among them Figure 1 The utility model provides a lightweight electric cylinder's main structure perspective view; Figure 2 The utility model provides a lightweight electric cylinder's main structure plane view; Figure 3A structural view of the side seat provided by this utility model.

[0024] In the specific implementation process, such as Figures 1-3 As shown, the device includes a base 1, on which a cylinder 2 and a servo motor 3 are mounted. The output shaft 4 of the cylinder 2 is fixed by a support 5. Several side seats 6 are fixed on the cylinder 2. Limiting rods 7 are installed through the side seats 6. The top of the limiting rods 7 is fixed to the support 5. A support shaft 8 is provided on one side of the side seat 6. Several through holes 9 are opened on one side of the limiting rods 7. One end of the support shaft 8 is inserted into the side seat 6 and extends into the side seat 6. When the output shaft 4 of the electric cylinder is working, the limiting rods 7 will be driven to move along with it. The limiting rods 7 can stabilize the output shaft 4, limit the lateral displacement of the electric cylinder under heavy load conditions, reduce vibration and shaking, and thus improve the accuracy of the motion trajectory.

[0025] A baffle 10 is fixed on the support shaft 8, and a spring 11 is sleeved on the support shaft 8. One end of the spring 11 is fixed on the baffle 10, and the other end of the spring 11 is fixed on the side seat 6. A lifting ring 12 is provided on one side of the cylinder body 2. Multiple protrusions 13 are fixed on the lifting ring 12. The protrusions 13 are located below the support shaft 8. Multiple guide rails 14 are fixed on the base 1. The guide rails 14 pass through the lifting ring 12 and are slidably connected to the lifting ring 12. An electric telescopic rod 15 is installed on the base 1. The output end of the electric telescopic rod 15 is fixed on the lifting ring 12. The end of the support shaft 8 away from the side seat 6 is rounded to ensure that the support shaft 8 can be pushed into the through hole 6 when the protrusion 13 moves upward.

[0026] A bracket 16 is installed on the base 1, and a cooling fan 17 is installed on the bracket 16. The exhaust side of the cooling fan 17 faces the servo motor 3. The housing of the servo motor 3 is made of aluminum alloy. The use of aluminum alloy housing for the servo motor 3 in this lightweight electric cylinder can significantly reduce the overall weight and also enhance its heat dissipation effect. Together with the cooling fan 17, it can quickly dissipate heat during long-term operation.

[0027] The working principle of this utility model is as follows: When the output shaft 4 of the electric cylinder is working, several limit rods 7 will be driven to move along with it, and the several limit rods 7 can stabilize the output shaft 4, limit the lateral displacement of the electric cylinder under heavy load conditions, reduce vibration and shaking, and thus improve the accuracy of the motion trajectory.

[0028] When the output shaft 4 is stationary and provides support, the electric telescopic rod 15 will drive the lifting ring 12 to move upward. When the protrusion 13 moves upward, the support shaft 8 will be pushed into the through hole 9, improving the self-locking capability of the output shaft 4. When the output shaft 4 needs to move, the electric telescopic rod 15 will drive the lifting ring 12 to move downward. Under the action of the spring 11, the support shaft 8 will disengage from the through hole 9, thereby canceling the fixation of the limit rod 7.

[0029] The circuit and the control involved in the utility model are prior art, and will not be described in detail here.
