Technical Field
The utility model relates to a slide rail especially relates to a ball formula linear slide rail.
Background
The linear slide rail is also called a linear guide rail, and a linear guide rail refers to a motion system which is composed of a linear track and a slide block and is used for reciprocating linear motion in a given direction. The linear guide rail can be divided into a roller type linear guide rail, a cylindrical type linear guide rail and a ball type linear guide rail according to the structure, and is widely applied to industrial automation. The system comprises the industries of aerospace, new energy, intelligent logistics, rail transit, medical equipment, furniture and home furnishing and the like.
Due to the influence of the product structure and the processing technology, the linear slide rail has the following defects:
a. the cylindrical ball guide rail has larger integral installation size due to the structure; the ball guide rail has higher requirements on the use environment; after long-time use, the gap between the sliding block and the track is increased due to the abrasion of the cylindrical track, so that the problems of shaking and the like are caused.
b. The ball type linear guide rail has the advantages of high precision and large load capacity, but due to the structure of the ball type slide block, the ball type linear guide rail cannot be freely separated from a track, the procedure is complicated during installation and disassembly, balls are easily lost, and the slide block is damaged. In addition, because the ball type linear guide rail has high precision, the precision requirement on the mounting surface is high, if certain errors exist in the processing of the mounting surface, the mounting work is extremely difficult, and the working efficiency is influenced.
In summary, a linear slide rail with a more suitable structure is needed to meet a plurality of demands of industries such as industrial automation, rail transit, intelligent logistics, medical instruments, special vehicles and the like.
