Description

Technical Field

[0001] The utility model relates to the field of servo motors, in particular to a servo motor with a lubrication structure. Background Art

[0002] With the rapid development of modern industrial automation and precision manufacturing technology, servo motors, as the core actuators of the control system, have a vital role in the operating efficiency and product quality of the entire system in terms of performance stability and accuracy. During the operation of the servo motor, due to the presence of friction, wear and other factors, the mechanical parts inside the motor will generate certain resistance and heat, which will not only reduce the operating efficiency of the motor, but may also have an adverse effect on the service life of the motor.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 , Figure 4 and Figure 5 The utility model provides an embodiment: a servo motor with a lubrication structure, including a servo motor 1, a delivery pipe 23 that can deliver lubricating oil to the bearing is arranged at the top of the servo motor 1, and a lubrication component is arranged at the top of the servo motor 1. The lubrication component includes a support plate 22 that supports the positioning sleeve 2 and the liquid storage tube 21. The bottom end of the support plate 22 is fixedly installed on the top of the servo motor 1, and a motor 4 that can drive the liquid storage tube 21 to rotate is fixedly installed on the left side of the support plate 22. The motor 4 is an existing structure and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The right side of the output shaft of the motor 4 is fixedly connected with a liquid storage tube 21 for storing lubricating liquid.

[0033] Furthermore, the delivery pipe 23 passes through and is fixedly connected to the right side of the support plate 22, and the right side of the support plate 22 is fixedly connected with a positioning sleeve 2 for providing support, the liquid storage tube 21 passes through and is rotatably connected to the inner wall of the positioning sleeve 2, and the inner wall of the bottom end of the positioning sleeve 2 is fixedly connected with an extrusion ring 26 which contacts the ball 24 and squeezes the ball 24 to make the lubricating liquid flow out, and the inner wall of the liquid storage tube 21 is fixedly connected with a support block 212 supporting the positioning block 210, and two groups are provided, and a positioning block 210 supporting the ball 24, a positioning rod 28, and a spring 27 is fixedly connected between the two groups of support blocks 212, and a circular groove 29 is provided on the front surface of the positioning block 210 for providing the positioning rod 28 with sliding extrusion spring 27 and supporting the ball 24.

[0034] Reference Figure 2 , Figure 3 and Figure 5 A liquid adding assembly is provided on the right side of the liquid storage tube 21 , and the liquid adding assembly includes a threaded sleeve 31 that can add lubricating liquid into the liquid storage tube 21 from the threaded sleeve 31 , and the threaded sleeve 31 is fixedly connected to the right side of the liquid storage tube 21 .

[0035] Reference Figure 3 , Figure 4 and Figure 5The extrusion ring 26 is set to a semicircular arc shape. By setting the extrusion ring 26 to a semicircular arc shape, the ball 24 can be squeezed so that the ball 24 moves inward and moves out of the discharge hole 211, so that the lubricating liquid can flow out from the discharge hole 211. The inner wall of the circular groove 29 is slidably connected with a positioning rod 28 supporting the ball 24. The bottom end of the positioning sleeve 2 is provided with a connecting hole 25 for providing the lubricating liquid to flow into the conveying pipe 23 and flow to the bearing. The connecting hole 25 is connected to the conveying pipe 23. The positioning rod 28 is elastically connected to the positioning block 210 through a spring 27. One end of the spring 27 is fixedly connected to the inner wall of the rear surface of the circular groove 29, and the other end of the spring 27 is fixedly connected to the rear surface of the positioning rod 28. The ball 24 is squeezed inward by the squeezing ring 26 to drive the positioning rod 28 to move and squeeze the spring 27. At this time, the lubricating fluid can flow out to the bearing. At the same time, when it stops being used, the reverse force of the squeezing of the spring 27 can drive the positioning rod 28 to reset, so that the ball 24 resets and slides into the discharge hole 211 to block the discharge hole 211, thereby preventing the lubricating fluid from flowing out and causing waste when not in use.

[0036] Reference Figure 2 , Figure 3 and Figure 4 The front surface of the positioning rod 28 is fixedly connected with a ball 24 which can block the discharge hole 211 and can be moved out of the discharge hole 211 to allow the lubricating liquid to flow to the bearing. The positioning rod 28 is slidably connected to the front surface of the positioning block 210. The outer wall of the front surface of the liquid storage tube 21 is provided with a discharge hole 211 for the lubricating liquid to flow out. The ball 24 slides on the inner wall of the discharge hole 211. The right end of the liquid storage tube 21 is close to the right side of the positioning sleeve 2 and is set to a transparent material, which can facilitate the observation of the amount of lubricating liquid in the liquid storage tube 21.

[0037] Reference Figure 1 , Figure 2 and Figure 5 The threaded sleeve 31 is connected to the inner wall of the liquid storage tube 21. The protective cover 3 can be moved out of the threaded sleeve 31 by rotating the protective cover 3. At this time, the lubricating liquid can be added into the liquid storage tube 21, which improves the efficiency and convenience of operation and reduces the tediousness and inconvenience caused by adding lubricating liquid. The right side of the threaded sleeve 31 is threadedly connected to the protective cover 3, and the left side of the protective cover 3 is fixedly connected to a rubber ring 32 that can increase the contact area and friction with the liquid storage tube 21, thereby increasing the sealing and stability of the connection.

[0038] Working principle: When in use, the liquid storage tube 21 is driven to rotate by starting the motor 4, and the rotation of the liquid storage tube 21 drives the positioning block 210 and the ball 24 to rotate. After the ball 24 rotates and contacts the extrusion ring 26, it is squeezed by the extrusion ring 26, so that the ball 24 moves inward, drives the positioning rod 28 to move the extrusion spring 27, and the ball 24 moves inward, so that the lubricating liquid flows out from the discharge hole 211, flows to the inner wall of the bottom end of the positioning sleeve 2, and then flows into the conveying pipe 23 through the connecting hole 25, and flows to the bearing in the servo motor 1 through the conveying pipe 23, so that the bearing can be lubricated. By arranging multiple groups of extrusion rings 26, balls 24, and discharge holes 211 in conjunction with the motor 4, the lubricating liquid can be continuously delivered, ensuring that during the operation of the servo motor 1, the bearings can always be fully and timely lubricated, effectively reducing friction and wear, and ensuring the stable performance and service life of the servo motor 1.

[0039] When the servo motor 1 is used up, the motor 4 is turned off, so that the extrusion ring 26 releases the extrusion of the ball 24. The reverse force of the extrusion of the spring 27 can drive the positioning rod 28 and the ball 24 to reset, thereby blocking the discharge hole 211 to prevent the lubricating liquid from flowing out and wasting. When it is necessary to add lubricating liquid, the protective cover 3 can be rotated to be threadedly connected with the threaded sleeve 31 so that the protective cover 3 is opened. At this time, the lubricating liquid can be conveniently added from the threaded sleeve 31. After adding, the protective cover 3 can be rotated to be threadedly connected with the threaded sleeve 31 so that the protective cover 3 can be opened. At this time, the lubricating liquid can be conveniently added from the threaded sleeve 31. After adding, the protective cover 3 can be rotated to be threadedly connected with the threaded sleeve 31 so that the protective cover 3 can be moved to drive the rubber ring 32 to contact the liquid storage tube 21, thereby increasing the contact area and friction with the liquid storage tube 21, and improving the stability and sealing of the connection of the protective cover 3, thereby improving the efficiency and convenience of operation, and reducing the tediousness and inconvenience that may be caused by adding lubricating liquid.
