Description

Technical Field

[0001] This utility model relates to the field of electric cylinders, specifically a structure for a vertically moving electric cylinder that applies balanced pressure. Background Technology

[0002] An electric cylinder is a modular product that integrates a servo motor and a lead screw, converting the rotary motion of the servo motor into linear motion.

[0003] In the current technology, electric cylinders use an electric motor as a power source. The motor generates rotational motion through current drive. This rotational motion is converted into linear motion through a transmission mechanism (usually a lead screw, nut, etc.). When the lead screw rotates, the nut that cooperates with the lead screw will move linearly along the axis of the lead screw, thereby realizing the extension and retraction of the electric cylinder.

[0004] However, existing electric cylinders have poor pressure uniformity during use; therefore, a balanced pressure vertical motion electric cylinder structure is proposed to address the above problem. Utility Model Content

[0024] Specific implementation examples are given below.

[0025] Please see Figure 1-5 As shown, a balanced pressure vertical motion electric cylinder structure includes an upper body 11 and a lower body 12, with a support rod 13 fixedly connected between the upper body 11 and the lower body 12; a ball screw 14 is rotatably connected to the middle of the upper body 11 and the lower body 12; a drive assembly capable of driving the ball screw 14 to rotate is installed on the upper body 11; a movable seat 15 is connected to the ball screw 14 through a ball screw nut pair; multiple push rods 16 are fixedly connected to the movable seat 15; sliding holes are opened on the upper part of the lower body 12 at positions corresponding to the push rods 16; the push rods 16 pass through the sliding holes; and a push plate 17 is fixedly connected to the end of the push rod 16 away from the movable seat 15.

[0026] The drive assembly includes a motor 21, a drive pulley, and a driven pulley. The motor 21 is fixedly mounted on the side of the upper body 11. The drive pulley is fixedly connected to the output shaft of the motor 21. The driven pulley is fixedly connected to the end of the ball screw 14. A transmission belt 22 is mounted on the drive pulley and the driven pulley.

[0027] In use, the upper seat 11 and the lower seat 12 are connected and fixed together by the support rod 13. The drive assembly is installed on the upper seat 11. The drive assembly drives the ball screw 14 to rotate. The rotation of the ball screw 14 will drive multiple moving seats 15 to move, thereby driving multiple push rods 16 to move. The push rods 16 pass through the sliding hole. The push plate 17 is moved by the multiple push rods 16. The push plate 17 applies pressure. The multiple push rods 16 cooperate to improve the pressure stability and balance of the electric cylinder's vertical pressure application.

[0028] The drive assembly includes a motor 21, which drives the lead screw to rotate via a drive pulley, a driven pulley, and a transmission belt 22.

[0029] Furthermore, such as Figure 1-5 As shown, a linear bearing 31 is fixedly connected to the middle of the sliding hole, the push rod 16 passes through the linear bearing 31 and slides with it, and a ball bearing 32 is installed at the rotatable connection of the ball screw 14; a pressure sensor 4 is fixedly installed at the bottom of the push plate 17.

[0030] During use, a linear bearing 31 is installed inside the sliding hole, and a ball bearing 32 is installed at the rotating part of the ball screw 14. This can improve the stability during the movement, reduce the friction during the movement, reduce noise, and improve accuracy.

[0031] Furthermore, such as Figure 1-5 As shown, there are four push rods 16 and four support rods 13, which are evenly distributed in a ring.

[0032] In use, the four push rods 16 and the support rods 13 are evenly distributed in a 360° ring to ensure the stability of pressure application.

[0033] Furthermore, such as Figure 1-5 As shown, a cylinder 5 is installed on the upper seat 11 and the lower seat 12; an air blowing seat 61 is fixedly connected to the bottom of the lower seat 12, and a through hole 62 is opened at the corresponding position of the push rod 16 on the air blowing seat 61. An air supply channel 64 is opened in the middle of the through hole 62, and a tapered opening 63 is opened at the end of the through hole 62 away from the air blowing seat 61.

[0034] During use, cylinders 5 are installed on the upper body 11 and the lower body, which serve as dustproof measures to facilitate use in high-dust environments. An air blowing seat 61 is installed at the bottom of the lower body 12. The air supply channel 64 of the air blowing seat 61 is connected to an external air pump through a corresponding pipe. The airflow will enter the through hole 62 along the air supply channel 64, and then be guided from the conical opening 63 below to blow onto the surface of the push rod 16, thereby removing dust from the surface of the push rod 16 and reducing wear on the push rod 16 in high-dust environments.

[0035] Working principle: During use, the upper seat 11 and the lower seat 12 are connected and fixed together by the support rod 13. The drive assembly is installed on the upper seat 11. The drive assembly drives the ball screw 14 to rotate. The rotation of the ball screw 14 will drive multiple moving seats 15 to move, thereby driving multiple push rods 16 to move. The push rods 16 pass through the sliding hole. The multiple push rods 16 drive the push plate 17 to move. The push plate 17 applies pressure. The multiple push rods 16 cooperate to improve the pressure stability and balance of the electric cylinder's vertical pressure application.

[0036] The drive assembly includes a motor 21, which is connected to the lead screw via a drive pulley, a driven pulley, and a transmission belt 22 to drive the lead screw to rotate. During use, a linear bearing 31 is installed inside the sliding hole, and a ball bearing 32 is installed at the rotating part of the ball screw 14. This improves stability and friction during operation, reduces noise, and increases precision. During use, the four push rods 16 and the support rod 13 are evenly distributed in a 360° ring to ensure the stability of pressure application. During use, a cylinder 5 is installed on the upper seat 11 and the lower seat to provide dust protection for use in dusty environments. An air blowing seat 61 is installed at the bottom of the lower seat 12. The air supply channel 64 of the air blowing seat 61 is connected to an external air pump through a corresponding pipe. The airflow enters the through hole 62 along the air supply channel 64 and is then guided from the conical opening 63 below to blow onto the surface of the push rod 16, thus removing dust from the surface of the push rod 16 and reducing wear on the push rod 16 in dusty environments.
