Technical Field

[0001] This utility model relates to the field of mechanical transmission technology, specifically a screw-fixed nut rotary transmission structure. Background Technology

[0002] Mechanical transmission is a technology that transmits motion and power through mechanical components. Its core is to convert the motion form, speed, or torque of the prime mover into the state required by the actuator. During the transmission process, the transmission of force and motion is achieved through direct contact or meshing between components. The screw and nut transmission structure is an important branch of mechanical transmission. It belongs to the core transmission form in the mechanical transmission system that converts rotary motion into linear motion. The two are related as part and whole. Mechanical transmission is a general term that covers a variety of transmission methods. The screw and nut transmission is a specific implementation method with a specific function and typical structure. However, in the existing screw and nut transmission structure, the screw arm is too long, resulting in insufficient rigidity. Vibration and abnormal noise occur during high-speed movement, affecting the transmission accuracy and making it inconvenient to use. Utility Model Content

A nut seat is sleeved on the surface of the lead screw, and a connecting frame is installed on the surface of the nut seat. A gear is rotatably installed inside the connecting frame. A sliding groove is installed on the surface of the base, and a slider is slidably installed inside the sliding groove. A motor is installed on the surface of the slider, and the output shaft of the motor is connected to the gear. A lubrication structure is provided on the surface of the main body.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the lead screw fixed nut rotary transmission structure: 1. A motor, gear, and connecting frame are provided. The nut seat is directly connected to the gear through the connecting frame. When the motor drives the gear to rotate, the gear meshes with the tooth blocks on the surface of the nut seat, causing the nut seat to rotate on the surface of the lead screw, so that the nut seat rotates along the thread on the surface of the lead screw, thereby positioning the lead screw. 2. An infrared sensor and an electromagnet are installed. The infrared sensor detects the position of the nut seat. When the nut seat is about to move to the bottom of the nozzle, the infrared sensor transmits an electrical signal to the control system. The control system then activates the electromagnet, causing its end to pop out. The electromagnet then pushes the storage bag through the push plate, causing the lubricating oil inside the storage bag to spray out. This lubricates the surface of the lead screw and improves the practicality of the device. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a screw-fixed nut rotary transmission structure, including a main body 10, a base 20, a fixed seat 201, a screw 202, a nut seat 30, a connecting frame 301, a gear 302, a motor 303, a slider 304, a slide groove 305, a support plate 40, a connecting sleeve 401, a storage bag 402, a nozzle 403, an infrared sensor 404, an electromagnet 405, and a push plate 406; This lead screw fixed nut rotary transmission structure facilitates lubrication of the lead screw 202 and improves its stability. The specific implementation method is as follows: A base 20 is installed inside the main body 10, and fixed seats 201 are symmetrically installed on the surface of the base 20. A lead screw 202 is fixedly connected between the two fixed seats 201. A nut seat 30 is sleeved on the surface of the lead screw 202, and a connecting frame 301 is installed on the surface of the nut seat 30. A gear 302 is rotatably installed inside the connecting frame 301. A slide groove 305 is installed on the surface of the base 20, and a slider 304 is slidably installed inside the slide groove 305. A motor 303 is installed on the surface of the slider 304, and the output shaft of the motor 303 is connected to the gear 302. A lubrication structure is provided on the surface of the main body 10. The lubrication structure includes: a support plate 40 is installed on the surface of the main body 10, and connecting sleeves 401 are installed at equal intervals on the surface of the support plate 40. A storage device is embedded inside the connecting sleeve 401. The storage bladder 402 has a nozzle 403 installed at its bottom. An infrared sensor 404 is installed on the surface of the support plate 40, and an electromagnet 405 is installed on the surface of the support plate 40. A push plate 406 is connected to the end of the electromagnet 405. The nut seat 30 has internal threads and is threaded to the lead screw 202. Tooth blocks are installed around the surface of the nut seat 30 and mesh with the gear 302. The nut seat 30 is rotatably connected to the connecting frame 301, and is threaded to the gear 302 and the connecting frame 301. The slider 304 is slidably connected to the groove 305. The bottom of the nozzle 403 is positioned corresponding to the lead screw 202, and the end of the push plate 406 is in contact with the surface of the storage bladder 402.

[0022] When the motor 303 is started, its output shaft drives the gear 302 to rotate synchronously, causing the gear 302 to rotate inside the connecting frame 301. Simultaneously, the gear 302 meshes with the toothed blocks surrounding the surface of the nut seat 30. As the gear 302 rotates, it drives the nut seat 30 to rotate through the meshing of the toothed blocks, causing the nut seat 30 to rotate on the surface of the lead screw 202. Because the nut seat 30 has internal threads, and the lead screw 202 between the fixed seats 201 is threaded, the nut seat 30 generates linear displacement along the threads on the surface of the lead screw 202 during rotation, achieving the conversion between rotational and linear motion. The nut seat 30 rotates inside the connecting frame 301, and during its linear motion, it pushes the connecting frame 301 to move, causing the connecting frame 301 to drive the gear 302 to move. The gear 302 drives the motor 303 to move, causing the bottom of the motor 303 to drive the slider 304 to move. The slider 304 slides inside the groove 305, causing the motor 303 to move synchronously with the nut seat 30. Infrared sensor 404 monitors the position of nut seat 30 in real time. When nut seat 30 is about to move to the bottom of a nozzle 403, the corresponding infrared sensor 404 sends a signal to the control system. The control system activates electromagnet 405. After electromagnet 405 is energized, its end extends out and pushes push plate 406 towards storage bladder 402. Under the action of the pushing force, storage bladder 402 is gradually squeezed. After storage bladder 402 is compressed, the lubricant inside it is sprayed out through nozzle 403. The nozzle 403 corresponds to the position of lead screw 202. The lubricant is accurately sprayed on the surface of lead screw 202 and simultaneously wets the contact area between nut seat 30 and lead screw 202, completing the lubrication operation.

[0023] Working principle: When using the lead screw fixing nut rotation transmission structure, a storage bag 402, a nozzle 403, an infrared sensor 404, an electromagnet 405, and a push plate 406 are provided to facilitate lubrication of the lead screw 202, improve the stability of the lead screw 202, and increase the overall practicality.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
