Description

TECHNICAL FIELD

[0001] The utility model relates to guide rail technical field, concretely is a kind of guide rail with good wear resistance. BACKGROUND

[0002] Guide rail: the groove or ridge made of metal or other materials, which can bear, fix, guide mobile devices or equipment and reduce their friction. The longitudinal groove or ridge on the surface of the guide rail is used to guide, fix machine parts, special equipment, instruments, etc. Guide rail is also called slide rail, linear guide rail or linear slide rail, which is used for linear reciprocating motion occasions. It has higher rated load than linear bearings and can withstand certain torque. It can realize high-precision linear motion under high load.

[0003] For example, the authorized announcement number "CN220726856U" is named a guide rail with good wear resistance. When the guide rail needs to be lubricated, the electric push rod drives the pressing plate to move inward, the pressing plate extrudes the sponge block, the lubricating oil enters the inside of the guide rail along the inclined block, the lubricating oil is coated, the staff can automatically coat the lubricating oil, and the wear resistance of the guide rail is improved. However, the existing guide rail with good wear resistance improves the wear resistance of the guide rail by placing the sliding block on the inner side of the guide rail and adding an anti-wear coating on the inner side of the guide rail. However, the main wear of the guide rail is caused by the frictional resistance of the contact between the sliding block side wall and the inner side of the guide rail. Therefore, as long as the sliding block side wall and the inner side of the guide rail come into contact and friction, the wear of the guide rail is inevitable. Therefore, the current wear-resistant coating method is a temporary solution, which affects the wear resistance of the guide rail with good wear resistance.

[0004] At the same time, the existing guide rail with good wear resistance improves the wear resistance by injecting lubricating oil into the guide rail and fully coating the lubricating oil in the guide rail with the sponge block. However, after absorbing the lubricating oil, the sponge block needs to be squeezed out for use. If the lubricating oil is not discharged in time after use, the lubricating oil will remain in the inner side of the guide rail and the inner side of the sponge block. After the guide rail stops running, the lubricating oil loses its carrier and easily solidifies. The solidified lubricating oil will not provide lubricating ability, causing blockage in the guide rail with good wear resistance and smooth sliding problems, which affects the working efficiency of the guide rail with good wear resistance.
