Description

  The present invention relates to a linear slide rail kit, and more particularly to a linear slide rail kit and a method of using the same.

As shown in FIG. 1, the main constituent members of a conventional linear slide rail 1 are a slide block 2, a slide rail 3 and a number of rolling balls 4 (steel balls), a dustproof piece, an end cover and its circulation member, a scrape, and a rolling. Such as a ball cage.
The conventional linear slide rail 1 is a mechanical assembly in which the slide block 2 performs linear motion along the slide rail 3 by utilizing infinite rolling circulation of the rolling ball 4 between the slide block 2 and the slide rail 3.
Since the linear slide rail 1 performs high-precision linear motion under a high load, it has gradually become one of the important parts in the localization and surveying systems of the precision science and technology industry and the precision machine industry.

However, as shown in FIG. 2, the linear slide rail 1 is subjected to a certain pre-pressure during assembly, so that the rolling ball 4 contacts between the slide block 2 and the slide rail 3 at a pre-installed contact angle.
Pre-installation is generally a 45 degree contact angle.
Thus, after a certain period of use, not only the rolling ball 4 itself is worn out, but also a few that show a straight line at the position where the slide block 2 and the slide rail 3 are in contact with the rolling ball 4 (pre-installation contact angle position). Is generated (see FIG. 3).
Thus, the localization accuracy is lowered and the transmission smoothness is poor.

A general countermeasure against this is to replace the entire linear slide rail 1, that is, the slide block 2, the slide rail 3, and the rolling ball 4 at the same time to ensure localization accuracy and smooth transmission.
However, this increases the cost of the maintenance equipment, especially because the manufacture of slide rails is the most difficult and the highest cost, so frequent replacements raise the maintenance costs of contractors.

  In the prior art, the entire linear slide rail is replaced in order to solve the problem of low localization accuracy and poor transmission smoothness, but this has a drawback of increasing the maintenance cost.

  The present invention relates to a linear slide rail kit that increases the number of times a slide rail is used, extends the service life of the slide rail, and lowers maintenance costs, and a method of using the same.

The linear slide rail kit according to the present invention includes a slide rail, a first slide block, some first rolling balls, a second slide block, some second rolling balls, a third slide block, and some third rolling balls.
On the outer surface of the slide rail, there are four rows of slide rail rolling groove tanks, and the four rows of slide rail rolling groove tanks are positioned on both sides of the slide rail in two rows.
The first slide block has a first perforation, and an inner surface of the first perforation has four rows of first slide block rolling groove tanks, and the four rows of first slide block rolling groove tanks are Two rows are positioned on two sides of the inner surface of the first perforation, and each first slide block rolling groove tank has a predetermined contact angle.
The second slide block has a second perforation, and an inner surface of the second perforation has four rows of second slide block rolling groove tanks, and the four rows of second slide block rolling groove tanks are Two rows are positioned on two sides of the inner surface of the second perforation, and the contact angle of each second slide block rolling groove tank is different from the contact angle of the first slide block rolling groove tank.
As a result, the first slide block and the first rolling ball are used correspondingly to the slide rail for a certain period of time, and a first wear track is formed on each slide rail rolling groove tank of the slide rail. Thus, when the accuracy and smoothness of the first slide block become poor, the first slide block and the first rolling ball are replaced, and the second slide block, the second rolling ball, and the The second rolling ball is driven to the second slide block rolling groove tank, and the second rolling ball is the movement track on each slide rail rolling groove tank of the slide rail. It is located outside the first wear track, which does not affect the accuracy and smoothness of the second slide block movement. .
In addition, a second wear track is formed on each slide rail rolling groove tank of the slide rail due to the wear, but the first wear track and the second wear track do not overlap each other.
Thereby, the service life of a slide rail can be extended by using a slide rail many times, and the effect which reduces a maintenance expense can be achieved.

The present invention further provides a method of using the linear slide rail kit, which includes the following steps.
On the outer surface of the slide rail, there are four rows of slide rail rolling groove tanks, and the four rows of slide rail rolling groove tanks are positioned on both sides of the slide rail in two rows.
Using the first slide block and some first rolling balls, the first slide block has a first perforation, and the inner surface of the first perforation has four rows of first slide block rolling groove tanks. The four rows of the first slide block rolling groove tanks are positioned on the two sides of the inner surface of the first perforation in two rows, and the first slide block rolling groove tanks have a predetermined contact angle. Each of the first rolling balls is in contact with the slide rail rolling groove tank of the slide rail and the first slide block rolling groove tank of the first slide block.
When the first slide block and the first rolling ball are used over a period of time on the slide rail, a first wear track is formed on each slide rail rolling groove tank of the slide rail due to wear. As a result, when the accuracy and smoothness of the first slide block become poor, the first slide block and the first rolling ball are removed from the slide rail.
Next, using the second slide block and some second rolling balls, the second slide block has a second perforation, and the inner surface of the second perforation has four rows of second slide block rolling groove tanks. The four rows of second slide block rolling groove tanks are located on the two sides of the inner surface of the second perforation in two rows, and the contact angle of each second slide block rolling groove tank and the The contact angle of the first slide block rolling groove tank is different, and each of the second rolling balls is in contact with the slide rail rolling groove tank of the slide rail and the second slide block rolling groove tank of the second slide block, The second slide block, the second rolling ball, and the slide rail can be continuously matched and used.
The second rolling ball is driven by the second slide block rolling groove tank, and the second rolling ball has a movement trajectory on each slide rail rolling groove tank of the slide rail located outside the first wear trajectory. Does not affect the accuracy and smoothness of the two slide block movement.
Thus, by using the slide rail many times, the service life of the slide rail can be extended, and the effect of reducing the maintenance cost can be achieved.
