Description

Linear slide group

This creation is related to linear slides, and more specifically to a linear slide set.

According to the first figure, the main components of the linear slide 1 are the slider 2, the slide rail 3 and the majority of the balls 4 (steel balls), and some other components such as the dustproof sheet, the end cover and the choke element thereof. The oil scraper and the ball retainer are mainly mechanical components that use the ball 4 to perform an infinite rolling cycle between the slider 2 and the slide rail 3 to linearly move the slider 2 along the slide rail 3, due to the linear slide rail 1 High-precision linear motion can be carried out under high load, so it has gradually become one of the important components in the positioning and measurement system of the precision technology industry and precision machinery industry. However, as shown in the second figure, the linear slide 1 has a certain pre-stress during assembly, and the ball 4 is contacted between the slider 2 and the slide rail 3 at a predetermined contact angle, generally 45 degrees. Contact angle. In this way, after using for a period of time, not only the balls 4 themselves will wear, but also the sliding track 2 and the sliding rails 3 at the position of contact with the balls 4 (predetermined contact angle position) will also produce a multi-track and straight-line wear track 5 (As shown in the third figure), which leads to a problem of lowering the positioning accuracy and poor transmission smoothness. In this case, the general method is to replace the entire set of linear slide rails 1, that is, the slider 2, the slide rail 3 and the balls 4, to ensure the positioning accuracy and the smoothness of the transmission. However, as a result, the cost of maintenance equipment will increase, especially the production of slide rails is the most difficult and the cost is the most expensive. Too frequent replacements will make the maintenance cost of the operators too high.

In view of this, the main purpose of the present invention is to provide a linear slide group which can increase the number of times the slide rail is used and extend the service life of the slide rail to achieve a reduction in maintenance cost. Therefore, the present invention provides a linear slide group, which mainly comprises: a slide rail having four rows of slide rail rolling grooves on the outer surface thereof, and the four rows of slide rail rolling grooves are two or two slides. a first slider having a first perforation, the inner surface of the first perforation having four rows of first slider rolling grooves, and the four rows of the first slider rolling grooves are two by two Positioned on two sides of the inner surface of the first perforation, and each of the first slider rolling grooves has a predetermined contact angle; a plurality of first balls; and a second slider having a second perforation The inner surface of the two perforations has four rows of second slider rolling grooves, the four rows of second slider rolling grooves are two or two on the two sides of the inner surface of the second perforation, and the second sliders The contact angle of the rolling groove is different from the contact angle of the first slider rolling groove; a plurality of second balls; thereby, the first slider and the first ball are first used with the sliding rail for a period of time, And after grinding a first wear track on each of the slide rail rolling grooves of the slide rail, replacing the first slider and the first a ball, and the second slider is used in combination with the second ball and the slide rail, the second ball is driven by the second slider rolling groove, and the second ball is on the sliding groove of each slide rail The motion trajectory is outside the first wear trajectory, so that the accuracy and smoothness of the displacement of the second slider are not affected, and a second wear trajectory is ground on each of the sliding rail grooves of the slide rail. The first wear track and the second wear track do not overlap each other, thereby achieving the effect of being able to use the slide rail multiple times and extending the service life of the slide rail to reduce the maintenance expenditure.
