Description

Linear Guides

The invention relates to the technical field of guide rails, in particular to a linear guide rail.

Linear guides are also called linear guides, slide guides, linear guides, and linear guides. They are mainly used in linear reciprocating motions, and can bear a certain torque, and can achieve high-precision linear motion under high load conditions; linear guides The function of movement is to support and guide the moving parts and perform reciprocating linear motion in a predetermined direction. Depending on the nature of the friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, and fluid friction guides. ; Linear bearings are mainly used in automatic machinery, linear guides are mainly used in mechanical structures with high accuracy requirements, such as machine tools, bending machines, laser welding machines, etc.

The existing linear guide generally includes a slide rail and a slider, wherein a slide groove is provided at the center of the bottom of the slider, the slider is arranged on the slide rail through the slide groove, and a plurality of ball slides are provided between the slide groove and the slide rail. To minimize the friction between the slider and the slide rail.

However, during the work of the linear guide, the critical section of the slider and the slide rail and the top surface of the track are prone to infiltration of foreign matter such as dust, which makes the sliding between the slider and the slide rail blocked, increasing the gap between the two. The frictional force, if foreign matter such as infiltrated dust accumulates excessively, may also cause the slider and the slide rail to detach.

Therefore, the present inventor was thinking about the idea of creation in view of this, and designed it based on many years of experience. After many discussions and trials, he experimented with samples, and revised and improved many times to launch the invention.

It is known that linear guides are prone to infiltrate foreign matter such as dust and cause accumulation between the slider and the slide rail. This is a technical problem to be solved.

According to the linear guide rail of the present invention, the linear guide rail includes a slide rail and a slide block, and a slide groove is provided at the bottom of the slide block. The slide block is provided on the slide rail through the slide groove. A slide rail is provided between the slide groove and the slide rail, and a rolling element is installed, so that the slider can be moved back and forth on the slide rail by the rolling element. The rolling element may be a ball or a roller. An upper retainer is further provided between the slide rail and the slider. The upper retainer is provided in the slider. A first spacer and a first retainer are respectively disposed at two ends of the upper retainer. Two spacers, the first spacer and the second spacer are connected through the upper holder, and the slider is disposed between the first spacer and the second spacer, Further, a middle holder and a lower holder are further provided between the slide rail and the slider. The middle holder and the lower holder are provided in the slider, and the middle holder is provided in the slider. On both sides of the slide rail, the lower retainer is disposed on the bottom end of the slide rail. Side, and two ends of the middle holder and the lower holder are respectively connected to the first spacer and the second spacer, and two ends of the slider are correspondingly provided with a first end dust wiper blade respectively. And a second end dust wiper blade, the first end dust wiper blade and the second end dust wiper blade are both slidably connected to the slide rail, and two ends of the slider are respectively provided with a first end cover correspondingly And a second end cap, the first end cap is disposed between the first spacer and the first end dust wiper, and the second end cap is disposed between the second spacer and the second spacer Between the second end dust wiper blades, both the first end cover and the second end cover are slidably connected to the slide rail; thereby, the linear guide can be formed.

According to the linear guide of the present invention, the arrangement of the upper holder can prevent dust on the top surface of the slide rail from entering the slide rail, and two spacers are provided at both ends of the upper holder, and the middle holder and the bottom are provided on both sides of the slide rail. Lower holders on both sides of the end further reduce the dust entering the linear guide.
