Description

The present invention relates to a linear slide device, and more particularly to a linear slide device and a dustproof holding structure thereof.

The application of the linear slide device in the industry is spreading day by day.
In addition to achieving a very precise transfer and supply effect, the linear slide device has many advantages such as a low friction consumption rate, high energy conversion performance, low noise, and high rigidity, which makes it difficult to break.

Lubricating oil is filled in the area corresponding to the rolling body of the slide rail and the slide block in order to reduce abrasion wear between the parts and realize smooth transfer.
However, these lubricating oils are extremely susceptible to the influence of the surrounding environment, and are liable to cause defective conditions such as dust adhering.
Or the problem that lubricating oil leaks also arises by the design of a structure.
Therefore, how to achieve dust prevention and leakage prevention is an important issue that the industry is working on.

As disclosed in Patent Document 1, a conventional linear slide device includes a slide rail, a slide block, and a dustproof cage.
The slide block includes a main slide block and two end covers connected to end portions of the main slide block.
The dustproof retainer is installed between the slide rail and the slide block, and the dustproof retainer extends from each rectangular end position of the rectangular substrate and the rectangular substrate. Is provided.
At the time of combination, the insertion sections are inserted into the end lids, respectively, and assembled and positioned.

However, the conventional linear slide device has the effect of preventing dust and preventing leakage, but these dustproof cages are consumed when used normally for a long time and must be replaced.
However, since the insertion section is inserted and fixed inside the end lid, in the process of replacement and assembly, the end lid can be removed first, and then the dustproof cage can be finally removed from the slide block.
This is inconvenient for maintenance, replacement of parts, and assembly, and further increases the working time of maintenance personnel, which increases the cost.
The present invention has been made in view of the above-described drawbacks of the conventional linear slide device and its dustproof holding structure.
