Description

Linear guide

This creation relates to the field of rail technology, and more particularly to a linear guide.

Linear guides, also known as line rails, slide rails, linear guides, linear slide rails, are mainly used for linear reciprocating motions, and can bear a certain torque, can achieve high-precision linear motion under high load; linear guide The function of the movement is to support and guide the moving parts, and make a reciprocating linear motion in a predetermined direction; according to the friction property, the linear motion guide rails can be divided into a sliding friction guide rail, a rolling friction guide rail, an elastic friction guide rail, a fluid friction guide rail, and the like. Linear bearings are mainly used in automation machinery. Linear guides are mainly used on mechanical structures with high precision requirements, such as machine tools, bending machines, laser welding machines, etc.

The existing linear guide rail generally includes a slide rail and a slider, wherein a slide groove is disposed at a center of the bottom of the slider, the slider is spanned on the slide rail through the sliding slot, and a plurality of ball slides are disposed between the sliding slot and the slide rail. So that the friction between the slider and the slide rail is minimized.

However, during the operation of the linear guide rail, foreign matter such as dust and the like are easily infiltrated at the critical section of the slider and the slide rail, and at the top surface of the rail, so that the sliding between the slider and the slide rail is blocked, which increases the relationship between the two. Friction, if foreign matter such as infiltrated dust accumulates excessively, it may also cause The slider is disengaged from the rail.

Therefore, how to develop and improve the shortcomings of the above-mentioned conventional linear guides is a goal that the relevant industry needs to work hard to develop. This creator has the idea of thinking and creating, and has designed with years of experience. This work was initiated by a multi-party discussion and trial sample test, and several revisions and improvements.

Conventional linear guides tend to penetrate foreign matter such as dust and accumulate between the slider and the slide rail, which is a technical problem to be solved.

The present invention provides a linear guide comprising: a slide rail and a slider, the slider bottom is provided with a sliding slot, and the slider is spanned on the slide rail through the sliding slot, A sliding passage is disposed between the sliding slot and the sliding rail and is mounted with a rolling element, so that the sliding member can be reciprocally displaced back and forth on the sliding rail by the rolling element, and the rolling element can be a ball or a roller An upper retainer is disposed between the slide rail and the slider, and the upper retainer is disposed in the slider, and a first spacer and a first spacer are respectively disposed on the two ends of the upper retainer a second spacer, the first spacer and the second spacer are connected by the upper holder, and the slider is disposed between the first spacer and the second spacer And the slide rail and the slider are further arranged There is a middle holder and a lower holder, the middle holder and the lower holder are disposed in the slider, the middle holder is disposed on both sides of the slide rail, and the lower holder is disposed at the The two sides of the bottom end of the slide rail, and the two ends of the middle retainer and the lower retainer are respectively connected to the first spacer and the second spacer, and the two ends of the slide rail are respectively correspondingly disposed The first end dustproof blade and the second end dustproof blade are slidably connected to the sliding rail, and the two ends of the sliding rail are respectively separated by a first end dustproof blade and a second end dustproof blade. Correspondingly, a first end cover and a second end cover are disposed, the first end cover is disposed between the first spacer and the first end dustproof blade, and the second end cover is disposed on the Between the second spacer and the second end dustproof blade, the first end cover and the second end cover are slidably connected to the slide rail, thereby obtaining a linear guide.

The present invention provides a linear guide rail which utilizes the arrangement of the upper retainer to prevent dust on the top surface of the slide rail from entering the slide rail, and two spacers are disposed at both ends of the upper retainer, and the middle retainer is disposed on both sides of the slide rail. The placement of the lower retainer on both sides of the bottom end further reduces dust entering the linear guide.
