Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a ball screw for facilitating lubrication, comprising: fixed lead screw 1, the nut 2, steel ball 3 and logical groove 4, fixed lead screw 1 outside is connected with nut 2, be connected with steel ball 3 between fixed lead screw 1 and the nut 2, it sets up in nut 2 to lead to groove 4, it installs fixed block 5 to lead to the groove 4 inner wall, the inside lubrication groove 6 of having seted up that runs through of fixed block 5, it has seted up seal groove 7 to lead to groove 4 inner wall, the inner wall that leads to groove 4 that is close to seal groove 7 has seted up draw-in

groove

8, 5 tops of fixed block are provided with seal 9, the outside of seal 9 that is close to seal groove 7 is connected with sealing washer 10, extrusion groove 11 has been seted up in the seal 9 top outside, extrusion groove 11 internal connection has spring 12, spring 12 one end is connected with fixture block 13, fixed block 5 and nut 2 structure as an organic whole, constitute block structure between fixture block 13 and the draw-in groove 8.

During specific implementation, normally, the mode of adding the lubricant through the ball screw is to add the lubricant after detaching the locking bolt inside the nut 2, the process is too troublesome, the seal block 9 can be pulled at the moment, the seal block 9 can be driven to move when moving, the spring 12 can be extruded when moving, the seal block 9 can be driven to move while moving, because the seal ring 10 is made of rubber, the seal block 9 can drive the clamp block 13 to move out of the inside of the clamping groove 8 when moving out of the seal groove 7 when the seal ring 10 is moved out of the seal groove 7, the lubricant can be added into the inside of the through groove 4 when moving out of the inside of the through groove 4, the lubricant can flow to the surface of the fixed block 5 through the through groove 4, the lubricant can flow into the inside of the nut 2 through the lubrication groove 6 inside of the fixed block 5 to contact with the steel ball 3, the lubricant can lubricate the steel ball 3 at the moment, the friction force of the steel ball 3 is reduced, and the rolling effect of the steel ball 3 is increased.

Referring to fig. 1,2,3 and 4, when lubricant is added to the ball screw, the lubricant can be quickly added without removing a locking bolt inside the nut 2.

Referring to fig. 1,2 and 3, the nut 2 is further provided with a first connecting ring 14, a second connecting ring 15 and an elastic hose 16, the first connecting ring 14 is mounted at both ends of the fixed screw 1, and the second connecting ring 15 is mounted on the outer circumferential surface of the left end of the nut 2. An elastic hose 16 is connected between the first connection ring 14 and the second connection ring 15 at the left end of the fixed screw 1. Another set of elastic hoses 16 is connected between the right end of the nut 2 remote from the second connection ring 15 and another set of first connection rings 14 at the right end of the fixed screw 1. The first connecting rings 14 are arranged in two groups symmetrically with respect to the center of the fixed screw 1.

During the concrete implementation, because fixed lead screw 1 on the ball exposes in the external world for a long time, external tiny dust can fall on fixed lead screw 1, influence fixed lead screw 1's life, because the outside of fixed lead screw 1 is provided with flexible hose 16, can extrude a set of elastic hose 16 through second go-between 15 and self when nut 2 drives steel ball 3 and rolls, stretch another set of elastic hose 16, and elastic hose 16 stretches the inner wall of elastic hose 16 when reaching the maximum distance also can not contact with fixed lead screw 1's the outside, elastic hose 16 can prevent dust fixed lead screw 1 this moment.

Referring to fig. 1,2 and 3, it can be seen that the fixed screw 1 on the ball screw is not contaminated by external dust.

In summary, when the ball screw convenient for lubrication is used, the elastic hose 16 is installed on the outer side of the fixed screw 1, and after the ball screw is used for a certain period of time, lubricant can be added to the surface of the steel ball 3 through the lubricating groove 6 inside the fixed block 5, so that the surface of the steel ball 3 is smoothed by the action of the lubricant, and the ball screw can work better.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
