[0002] Linear guides are also called linear rails, slide rails, linear guides, linear slides, etc. They are mainly divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. Linear guides are usually used in high-precision or high-speed linear reciprocating motion occasions, and can bear a certain torque, and can achieve high-precision linear motion under high load. In the process of linear motion, in order to improve the efficiency of the movement, lubricating grease needs to be applied to the guide rail.

[0003] Existing linear guides need to be repeatedly sprayed with lubricating oil when running for a long time to reduce the friction between the roller and the guide. Manual spraying of lubricating oil consumes a lot of time and energy, reducing the efficiency of the use of linear guides. At the same time, the firmness of the movement of the two sides of the linear motion guide under high load is poor, and derailment may occur. Utility Model Content

[0008] Furthermore, an oil filling port is provided on the upper end surface of the main rail, and the oil filling port is sealed by a sealing bolt. A plurality of transparent windows are provided on the outer side of the main rail.

[0009] Furthermore, second auxiliary slideways are provided on both sides of the main rail, and the auxiliary slideways are provided with a plurality of flow openings communicating with the second auxiliary slideways.

[0010] Furthermore, the auxiliary support frame is an arc-shaped ladder-shaped support frame that diffuses support outwards, and the lower end of the ladder-shaped support frame is rotatably connected to a roller that rotates in the second auxiliary slideway.

[0011] Furthermore, each corner of the upper end surface of the main guide rail is an arc surface structure, the main guide rail is an aluminum alloy stainless steel plate, and an anti-rust layer is provided on the main guide rail.

[0012] Furthermore, the model of the micro pump is WPY350.
