[0029] The inner wall bottom of installation shell 1 is provided with connecting mechanism 3, connecting mechanism 3 includes fixed shell 31 being fixedly connected to the inner wall bottom of installation shell 1, the inner wall left side of fixed shell 31 is rotatably connected with bidirectional threaded rod 32, the right end of screw rod is passed through annular nozzle 24, then rotate turntable 33, turntable 33 drives bidirectional threaded rod 32 to rotate.

[0030] The right end of the bidirectional threaded rod 32 is rotatably extended to the outside of the fixed shell 31, and the right end of the bidirectional threaded rod 32 is fixedly connected with a rocking disc 33. The outer wall of the reciprocating lead screw 22 is slidably connected with a second sliding shell 34. The rocking disc 33 drives the bidirectional threaded rod 32 to rotate, and the bidirectional threaded rod 32 drives the two third sliding shells 38 and the two circular shells 39 to slide on the inner wall of the fixed shell 31 and move to the center thereof, so as to adaptively clamp the lead screw.

[0031] The two second sliding shells 34 are symmetrically arranged with the mounting shell 1 as the center axis. The inner wall bottom of the mounting shell 1 is fixedly connected with a storage shell 35 for storing lubricant.

[0032] The top of the storage shell 35 is hingedly connected with a cover shell 36. The other end of the connecting pipe 25 is in communication with the left side of the storage shell 35 and is fixedly connected. The motor 21 drives the reciprocating lead screw 22 to rotate, and the reciprocating lead screw 22 drives the first sliding shell 23, the annular nozzle 24 and the connecting pipe 25 to rotate and reciprocate left and right. Then, the liquid pump 37 is started to deliver the lubricant to the inside of the annular nozzle 24 through the connecting pipe 25 for spraying, so as to realize uniform spraying of the lead screw left and right reciprocally.

[0033] The outer wall of the connecting pipe 25 is fixedly connected with the liquid pump 37. The bottom of the liquid pump 37 is fixedly connected with the inner wall bottom of the mounting shell 1. The reciprocating lead screw 22 is driven to rotate by starting the motor 21. The reciprocating lead screw 22 drives the first sliding shell 23, the annular nozzle 24 and the connecting pipe 25 to rotate and reciprocate left and right. Then, the liquid pump 37 is started to deliver the lubricant to the inside of the annular nozzle 24 through the connecting pipe 25 for spraying, so as to realize uniform spraying of the lead screw left and right reciprocally.

[0034] The outer wall of the bidirectional threaded rod 32 is threadedly sleeved with a third sliding shell 38. The two third sliding shells 38 are symmetrically arranged with the mounting shell 1 as the center axis. The top of the two third sliding shells 38 is fixedly connected with the bottom of the two second sliding shells 34. At the same time, the two third sliding shells 38 drive the two second sliding shells 34 to slide on the outer wall of the reciprocating lead screw 22 and move to the center of the reciprocating lead screw 22. According to the length of the lead screw, the first sliding shell 23 and the annular nozzle 24 are limited in the travel path of the reciprocating lead screw 22, so that the annular nozzle 24 can reciprocate and spray according to the length of the lead screw.

[0035] The outer walls of the two third sliding shells 38 are slidably connected to the inner wall of the fixed shell 31. Circular shells 39 are fixedly connected to the right side of the left third sliding shell 38 and the left side of the right third sliding shell 38. A rocker plate 33 drives a bidirectional threaded rod 32 to rotate. The bidirectional threaded rod 32 drives the two third sliding shells 38 and the two circular shells 39 to slide along the inner wall of the fixed shell 31 and move towards its center to adapt and clamp the lead screw. Simultaneously, the two third sliding shells 38 drive the two second sliding shells 34 to slide along the outer wall of the reciprocating lead screw 22 and move towards its center. The length of the lead screw limits the travel path of the first sliding shell 23 and the annular nozzle 24 on the reciprocating lead screw 22, allowing the annular nozzle 24 to reciprocate and spray according to the length of the lead screw. This operation allows for spraying of lead screws of different lengths, achieving wider applicability. Furthermore, the cooperation between the reciprocating lead screw 22 and the second sliding shell 34 ensures precise lubrication of the lead screw, avoiding over-lubrication or under-lubrication.

[0036] One specific application of this embodiment is: the liquid pump 37, which plays the role of delivering lubricating oil in the precision lubrication device for the lead screw. The liquid pump can draw lubricating oil from the storage shell and deliver it to the lubrication point of the lead screw through the connecting pipe. By adjusting the operating parameters of the liquid pump, the flow rate and pressure of the lubricating oil can be controlled to ensure that the lubricating oil can cover the surface of the lead screw and reduce friction and wear.

[0037] When using this device, open the cover 36, pour the lubricant into the storage shell 35, place the lead screw through the connecting mechanism 3, and then start the motor 21. The motor 21 drives the reciprocating lead screw 22 to rotate, which in turn drives the first sliding shell 23, the annular nozzle 24, and the connecting pipe 25 to rotate and move back and forth. Then, start the liquid pump 37 to deliver the lubricant through the connecting pipe 25 to the inside of the annular nozzle 24 for spraying, achieving uniform spraying of the lead screw by reciprocating left and right. The lead screw 22 drives the first sliding housing 23, the annular nozzle 24, and the connecting pipe 25 to rotate and move back and forth. Then, the liquid pump 37 is started to deliver the lubricant through the connecting pipe 25 to the inside of the annular nozzle 24 for spraying, so as to achieve uniform spraying of the lead screw back and forth. Through the above operation, it can be ensured that the lubricant is evenly sprayed on the surface of the lead screw, avoiding the problem of uneven application by manual application. Uniform lubrication can effectively reduce friction during the operation of the lead screw, reduce wear, improve the accuracy and performance of the lead screw, and at the same time reduce wear on the surface of the lead screw and extend its service life.

[0038] When using this device, the right end of the lead screw is passed through the annular nozzle 24, and then the rocker 33 is rotated. The rocker 33 drives the bidirectional threaded rod 32 to rotate. The bidirectional threaded rod 32 drives the two third sliding shells 38 and the two circular shells 39 to slide on the inner wall of the fixed shell 31 and move towards its center to adapt and clamp the lead screw. At the same time, the two third sliding shells 38 drive the two second sliding shells 34 to slide on the outer wall of the reciprocating lead screw 22 and move towards the center of the reciprocating lead screw 22. The length of the lead screw limits the travel path of the first sliding shell 23 and the annular nozzle 24 on the reciprocating lead screw 22, so that the annular nozzle 24 can reciprocate according to the length of the lead screw for spraying. The rocker 33 drives the bidirectional threaded rod 32 to rotate. 32 drives the two third sliding shells 38 and the two round shells 39 to slide on the inner wall of the fixed shell 31 and move towards its center to adapt and clamp the lead screw. At the same time, the two third sliding shells 38 drive the two second sliding shells 34 to slide on the outer wall of the reciprocating lead screw 22 and move towards the center of the reciprocating lead screw 22. The first sliding shell 23 and the annular nozzle 24 are restricted in their travel path on the reciprocating lead screw 22 according to the length of the lead screw, so that the annular nozzle 24 can reciprocate according to the length of the lead screw to perform spraying. Through the above operation, it can adapt to the spraying of lead screws of different lengths, achieving a wider range of applicability. At the same time, the cooperation of the reciprocating lead screw 22 and the second sliding shell 34 achieves precise lubrication of the lead screw, avoiding the problems of over-lubrication or insufficient lubrication.
