Technical Field

[0001] This utility model relates to the field of lead screw technology, specifically a high-precision pressure lead screw. Background Technology

[0002] In rolling mills in industries such as steel, metallurgy, and mining, the pressing screw is connected to the pressing roll via a nut and a screw drive. Rotating the screw controls the roll gap size and the amount of material reduction, pushing the material between the rolling mill rolls to achieve compression and shape change.

[0003] Existing high-precision lead screws often have their screws exposed. To ensure the normal operation of the lead screw, the screw and nut need to be effectively lubricated. However, adding lubricant is inconvenient, thus lacking practicality. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a high-precision lead screw, which has the following advantages:

[0015] This invention has the advantage of facilitating the application of lubricant to the surface. The operator places the threaded sleeve on the lead screw body, adds lubricating oil to the storage tank through the filling pipe, and then rotates the threaded sleeve. At the same time, the pump body is turned on, causing the pump body to draw the lubricating oil in the storage tank into the L-shaped pipe. After entering the pipe body, the lubricating oil is driven into the thread groove of the lead screw body by the rolling of the balls, thus facilitating the application of lubricating oil to the surface of the lead screw body and solving the problem of the inconvenience of adding lubricant.

[0025] 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.

[0026] Example 1

[0027] See Figure 1-4 A high-precision lead screw, characterized in that it includes a lead screw body 1; a lubrication assembly 2 is provided on the lead screw body 1, the lubrication assembly 2 including: a threaded sleeve 21, threadedly connected to the outer wall of the lead screw body 1; a storage tank 22, provided on the threaded sleeve 21; a liquid filling pipe 23, inserted into the storage tank 22; a pump body 24, provided on the storage tank 22, with its water inlet end inserted into the storage tank 22 and fixedly connected to the storage tank 22; an L-shaped pipe 25, fixedly connected to the water outlet end of the pump body 24; a pipe body 26, provided on the L-shaped pipe 25; a ball bearing 27, rotatably connected to the inner wall of the pipe body 26; a housing 4 is fixedly connected to the outer wall of the L-shaped pipe 25, and a plurality of pipe bodies 26 are provided on the housing 4, and a ball bearing 27 is rotatably connected to the inner wall of each pipe body 26; a hydraulic pressure sensor 5 is provided on the housing 4.

[0028] When ready for use, the operator places the threaded sleeve 21 onto the screw body 1, opens the valve on the filling pipe 23 to add lubricating oil into the storage tank 22 through the filling pipe 23, and then closes the valve on the filling pipe 23. Then, the operator rotates the threaded sleeve 21, simultaneously turning on the pump body 24. The pump body 24 draws the lubricating oil from the storage tank 22 into the L-shaped pipe 25, and then into the pipe body 26. Through the rolling of the balls 27, the lubricating oil enters the threaded groove of the screw body 1, thus facilitating the application of lubricating oil to the surface of the screw body 1. This improves the practicality of the device. After the lubricating oil in the L-shaped tube 25 enters the housing 4, it can enter multiple tubes 26, thereby simultaneously lubricating through multiple balls 27, improving the lubrication effect and application efficiency. After the lubricating oil in the housing 4 is full, the hydraulic pressure sensor 5 transmits an electrical signal to the distribution box, which then transmits the electrical signal to the controller. The controller then transmits the electrical signal to the pump body 24, which automatically shuts down and stops replenishing lubricating oil into the housing 4. This prevents the pump body 24 from running continuously after the housing 4 is full, thus improving the stability of the device.

[0029] Example 2

[0030] See Figure 1-4Based on Embodiment 1, auxiliary functions have been added;

[0031] The lead screw body 1 is provided with an auxiliary component 3, which includes: a slide rod 31, which is fixedly connected to the bottom of the storage tank 22, two of which are symmetrically arranged and both are slidably connected to the threaded sleeve 21; a spring 32, which is provided on the storage tank 22; multiple springs 32 are provided, and each spring 32 is fixedly connected at both ends to the bottom of the storage tank 22 and the outer wall of the threaded sleeve 21 respectively; and a one-way valve 6 is provided on the liquid filling pipe 23.

[0032] During use, the spring 32 pulls the storage box 22 towards the center of the screw body 1, and the position of the storage box 22 is restricted by the slide rod 31, so that the storage box 22 drives the ball bearings 27 on the box body 4 to always be in close contact with the screw body 1, thereby improving the coating effect; multiple springs 32 can increase the tension of the springs 32 on the device, further improving the coating effect; the one-way valve 6 on the liquid filling pipe 23 can eliminate the need to open or close the valve on the liquid filling pipe 23 before and after adding lubricating oil to the device, improving the convenience of the device.

[0033] 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.
