Description

Linear slide group and use method thereof

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

As shown in the first figure, the main components of the linear slide rail 1 are the slider 2, the slide rail 3, and most of the balls 4 (steel balls), and some other components, such as dust wipers, end caps and flow elements. Oil scraper and ball retainer, which are mainly mechanical components that use ball 4 to perform an infinite rolling cycle between the slider 2 and the slide rail 3 to make the slider 2 move linearly along the slide rail 3. It can perform high-precision linear motion under high load, so it has gradually become one of the important components in positioning and measuring systems of precision technology industry and precision machinery industry. However, as shown in the second figure, the linear slide rail 1 will have a certain preload during assembly, and the ball 4 will contact the slide rail 2 and the slide rail 3 at a preset contact angle, which is generally 45 degrees. Contact angle. In this way, after using for a period of time, not only the ball 4 itself will wear, but also the slider 2 and the slide rail 3 in contact with the ball 4 (preset contact angle position) will generate multiple, linear wear tracks 5 (As shown in the third figure), which in turn leads to problems of reduced positioning accuracy and poor transmission smoothness. Here, the general practice is to replace the entire set of linear slide rails 1, that is, the slide rails 2, the slide rails 3 and the balls 4, in order to ensure the accuracy of positioning and the smoothness of transmission. However, in this way, it will cause the cost of maintenance equipment to increase, especially the slide rail manufacturing is the most difficult, the cost is the most expensive, too frequent replacement will make the maintenance cost of the industry too high.

In view of this, the main purpose of the present invention is to provide a linear slide rail group and a method for using the same, which can increase the number of times the slide rail is used and extend the service life of the slide rail, so as to reduce the maintenance cost. For this reason, the present invention provides a linear slide rail group, which mainly includes: a slide rail with four rows of slide rail rolling grooves on its outer surface, the two rows of two On both sides of the rail; a first slider with a first perforation, the inner surface of the first perforation has four rows of first slider rolling grooves, and the four rows of first slider rolling grooves are two or two Located 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 number of first balls; a second slider having a second perforation, the first The inner surface of the two perforations has four rows of second slider rolling grooves, and the four rows of second slider rolling grooves are two or two on 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 rolling groove of the first slider; a number of second balls; thereby, the first slider and the first ball are first used with the slide rail for a period of time, After grinding a first wear track on each of the rolling grooves of the slide rail, the accuracy and smoothness of the first slider are caused. When it is not good, the first slider and the first ball are replaced, and the second slider is used with the second ball and the slide rail. The second ball is subject to the rolling groove of the second slider. Driven, the movement track of the second ball on each of the slide track rolling grooves falls outside the first wear track, so that the accuracy and smoothness of the displacement of the second slide is not affected, and is in the slide track. A second wear trajectory is ground on each of the rolling grooves of each slide rail, and the first wear trajectory and the second wear trajectory do not overlap each other, thereby achieving the ability to use the slide rail multiple times and extending the service life of the slide rail to reduce Maintain the effectiveness of expenditure. This creation also provides a method for using a linear slide rail group, which mainly includes the following steps: taking a slide rail, the outer surface of the slide rail has four rows of slide rail rolling grooves, and the four rows of slide rail rolling grooves are Two and two sides are on both sides of the slide rail; a first slider and a plurality of first balls are taken, the first slider has a first perforation, and the inner surface of the first perforation has four rows of first slides Block rolling grooves, the four rows of first slider rolling grooves are two or two on two sides of the inner surface of the first perforation, and each of the first slider rolling grooves has a predetermined contact angle, etc. The first ball is in contact with the rolling groove of the sliding rail of the sliding rail and the rolling groove of the first sliding block of the first sliding block; the first sliding block and the first rolling ball are used on the sliding rail for a period of time. And after grinding a first wear track on each of the rolling grooves of the slide rail, resulting in poor accuracy and smoothness of the first slide block, the first slide block and the first ball Remove from the slide rail, and then take a second slider and a number of second balls, the second slider has a second perforation, the first The inner surface of the perforation has four rows of second slider rolling grooves. The four rows of second slider rolling grooves are two or two on two sides of the inner surface of the second perforation, and the second sliders roll. The contact angle of the groove is different from the contact angle of the rolling groove of the first slider. The second balls are in contact with the rolling groove of the sliding rail of the slide rail and the rolling groove of the second slider of the second slider. Inside, and the second slider and the second ball continue to be used with the slide rail, the second ball is driven by the rolling groove of the second slider, and the second ball is on the rolling groove of each slide rail The motion trajectory falls outside the first wear trajectory, so that the accuracy and smoothness of the displacement of the second slider are not affected, so as to achieve the ability to use the slide rail multiple times and extend the service life of the slide rail, thereby reducing maintenance costs. The effect of expenditure.
