A sliding plate 8 is provided between the two connecting plates 7, and a sliding groove 9 is provided above the connecting plate 7 and the sliding plate 8, and a threaded seat 10 is provided at the bottom of the sliding plate 8. The threaded seat 10 is arranged in the guide rail groove 5 and is threadedly connected to the threaded rod 6, and the connecting plate 7 is arranged in the connecting groove 4; a lubrication mechanism is provided on the slide seat 2 to realize the lubrication function of the linear slide composed of the linear guide rail 1 and the slide seat 2.

[0026] Specifically, the lubrication mechanism includes a lubrication port 11, a lubrication pipe 12 and a connecting port 13. A threaded hole is provided on the threaded seat 10, and a lubrication port 11 is provided on the threaded seat 10 above the threaded rod 6. A connecting port 13 is provided on one side of the top of the slide seat 2. The connecting port 13 is connected to the lubrication port 11 through a lubrication pipe 12. The lubrication pipe 12 is arranged inside the slide seat 2, the connecting plate 7 and the sliding plate 8. Through existing oil injection equipment, such as an oil injection pump and an oil injection pipe, the oil injection pipe is connected to the connecting port 13, and the lubricating liquid is injected from the connecting port 13 through the lubrication pipe 12, and the lubricating liquid is injected into the threaded rod 6 in the guide rail groove 5 through the lubrication port 11. As the slide seat 2 moves, the lubrication function of the linear slide is realized.

[0027] Furthermore, the driving mechanism 3 includes a driving box 31, a worm gear 32, a worm 33 and a servo motor 34. A driving box 31 is provided at one end of the linear guide rail 1. A worm gear 32 and a worm 33 are provided inside the driving box 31. The worm gear 32 and the worm 33 are meshingly arranged. One side of the worm gear 32 is connected to one end of the threaded rod 6 through a connecting shaft, and one end of the worm 33 is connected to the output end of the servo motor 34 through a coupling. The servo motor 34 is mounted on one side of the driving box 31 through a motor. The servo motor 34 drives the worm 33 in the driving box 31 to rotate. The rotation of the worm 33 drives the worm wheel 32 meshing with it to rotate. The rotation of the worm wheel 32 drives the threaded rod 6 to rotate inside the guide rail groove 5 through the connecting shaft.

[0028] Furthermore, the connecting groove 4 and the connecting plate 7 are both arranged in an inclined structure, and the lower inclined end of the connecting groove 4 and the connecting plate 7 is arranged away from the threaded rod 6. The connecting groove 4 and the connecting plate 7 have a structure that is high inside and low outside, which can prevent dust from entering the threaded rod 6 and the guide groove 5 inside the linear guide 1 from the connecting groove 4. The opposite sides of the top of the linear guide 1 are both arranged in a groove structure, and the upper end of the sliding groove 9 is arranged corresponding to the groove structure at the top of the linear guide 1. The structure between the linear guide 1 and the slide seat 2 is compact and the sliding is stable.

[0029] Furthermore, limiting grooves 14 are provided at the lower ends of the opposite sides of the linear guide rail 1, and limiting sliders 15 are provided on the slide seat 2 below the connecting plate 7. The limiting sliders 15 are slidably arranged in the limiting grooves 14. When the slide seat 2 slides on the linear guide rail 1, the limiting sliders 15 on the opposite sides of the slide seat 2 slide in the limiting grooves 14 on the opposite sides of the linear guide rail 1, thereby increasing the stability of the sliding structure of the slide seat 2 on the linear guide rail 1.

[0030] Furthermore, mounting plates are provided on opposite sides of the linear guide rail 1, and assembly holes are provided on the mounting plates to facilitate the installation of the linear guide rail 1. The connecting groove 4 and the limiting slide groove 14 are set to the same length, and the mounting plates are provided on the linear guide rail 1 at the opposite ends of the limiting slide groove 14. The installation of the mounting plates will not hinder the sliding of the slide seat 2 on the linear guide rail 1.

[0031] Furthermore, a recessed groove is provided on one side of the top of the slide seat 2, and the connecting port 13 is provided inside the recessed groove. A sealing plug is provided in the recessed groove so that the connecting port 13 does not affect the flatness of the top of the slide seat 2, and the sealing plug blocks the connecting port 13 to prevent dust from entering the connecting port 13 when the oil is not filled.

[0032] The usage method of this embodiment is as follows: the servo motor 34 drives the worm 33 in the drive box 31 to rotate, and the rotation of the worm 33 drives the worm gear 32 engaged with it to rotate, and the rotation of the worm gear 32 drives the threaded rod 6 to rotate inside the guide rail groove 5 through the connecting shaft, and the threaded seat 10 threadedly connected on the threaded rod 6 moves inside the guide rail groove 5. The movement of the threaded seat 10 drives the connecting plate 7 to slide inside the connecting groove 4 through the sliding plate 8, and the limiting sliders 15 on the opposite sides of the slide seat 2 slide within the limiting slide grooves 14 on the opposite sides of the linear guide 1, thereby driving the slide seat 2 to slide on the linear guide 1 through the driving mechanism 3. Since the guide rail groove 5 and the threaded rod 6 are arranged inside the linear guide 1, and the connecting plate 7 and the connecting groove 4 are arranged in an inclined structure with the inside high and the outside low, it can greatly reduce the entry of dust into the inside of the guide rail groove 5, and avoid dust increasing the threaded rod 6. The friction resistance between the linear guide 1 and the threaded seat 10, and between the threaded seat 10 and the guide rail groove 5, makes the linear slide composed of the linear guide 1 and the slide seat 2 have a good dust-proof function; and the worm wheel 32 and the worm 33 cooperate to realize the drive of the linear slide, and the self-locking, smooth transmission and compact structure of the worm wheel 32 and the worm 33 are used to make the linear slide slide stably; remove the sealing plug in the recessed groove on the connecting port 13, connect the oil filling pipe to the connecting port 13, and use the existing oil filling equipment to inject the lubricating liquid from the connecting port 13 through the lubrication pipe 12, and inject the lubricating liquid into the threaded rod 6 in the guide rail groove 5 through the lubrication port 11. As the slide seat 2 moves, the linear slide is lubricated; the dust-proof and lubrication functions of the linear slide are combined to reduce the influence of dust on the guide rail groove 5 and the threaded rod 6 during operation and effectively reduce wear, so that the linear slide slides smoothly and with low wear.
