Description

Linear slide rail set and its use method

technical field

The invention relates to the technical field of linear slide rails, and more specifically refers to a linear slide rail set and a method for using the same.

Background technique

As shown in Figure 1, the main components of the linear slideway 1 are the slider 2, the slideway 3 and the multi-grain ball 4 (steel ball), and some other components, such as the dust-proof sheet, the end cover and its return element, the oil scraper Sheet and ball retainer, which mainly use the ball 4 to perform infinite rolling cycle between the slider 2 and the slide rail 3, so that the slider 2 can move linearly along the slide rail 3. Since the linear slide rail 1 can operate under high load Therefore, it has gradually become one of the important components in the positioning and measurement system of the precision technology industry and the precision machinery industry.

However, as shown in Figure 2, the linear slide rail 1 will have a certain preload during assembly, and make the ball 4 contact with a preset contact angle between the slider 2 and the slide rail 3, generally 45 degrees of contact horn. In this way, after using for a period of time, not only the ball 4 itself will be worn out, but also the position where the slider 2 and the slide rail 3 are in contact with the ball 4 (preset contact angle position) will produce multiple linear wear tracks 5 (as shown in Figure 3), which in turn leads to the 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 slider 2 , the slide rail 3 and the ball 4 synchronously, so as to ensure the accuracy of positioning and the smoothness of transmission. However, in this way, the cost of maintaining the equipment will increase, especially the manufacturing of slide rails is the most difficult and the cost is also the most expensive. Too frequent replacement will make the maintenance cost of the industry too high.

Therefore, the above is the introduction of each component of the linear slide rail assembly 100 provided by the first preferred embodiment of the present invention, and then its assembly method and its use characteristics are introduced as follows:

Firstly, the slide rail 90 is taken, and the slide rail 90 is inserted into the first through hole 111 of the first slide block 11, and the first ball 12 is located between the slide rail rolling groove 91 and the slide rail rolling groove 91 of the slide rail 90. The first sliding block rolling groove 112 of the first sliding block 11 exerts a preload on the sliding rail 90 and the first sliding block 11 , so that the first ball 12 and the sliding rail of the sliding rail 90 The inner wall surface of the rolling groove 91 is in contact with the lowest point of the inner wall surface of the first slider rolling groove 112 of the first slider 11 (as shown in FIG. 4 ), and the contact angle is 35 degrees.

After the slide rail 90 and the first slider 11 have been used for a period of time, the inner wall surfaces of each slide rail rolling groove 91 of the slide rail 90 and the inner wall surfaces of each first slider rolling groove 112 of the first slider 11 , after being worn out by the first ball 12 to form a linear first wear track 13 (as shown in Figure 7, only the slide rail 90 is shown), when the accuracy and smoothness of the first slider 11 are not good, then The first slider 11 and the first ball 12 can be removed from the slide rail 90 .

Next, the slide rail 90 is inserted into the second through hole 211 of the second slide block 21 , the second ball 22 is located between the slide rail rolling groove 91 of the slide rail 90 and the second slide rail 21 of the second slide block 21 . slide block rolling groove 212, and apply a preload to the slide rail 90 and the second slide block 21, so that the second ball 22 and the slide rail rolling groove 91 inner wall surface of the slide rail 90 and the The lowest point of the inner wall surface of the second slider rolling groove 212 of the second slider 21 contacts (as shown in FIG. 5 ), and its contact angle is 45 degrees. The second ball 22 is driven by the second slider rolling groove 212, The movement track of the second ball 22 in each slide rail rolling groove 91 of the slide rail 90 falls outside the first wear track 13, so that the accuracy and smoothness of the displacement of the second slide block 21 are not affected.

After the slide rail 90 and the second slide block 21 have been used for a period of time, the inner wall surfaces of each slide rail rolling groove 91 of the slide rail 90 and the inner wall surfaces of each second slide block rolling groove 212 of the second slide block 21 , after the second ball 22 wears out a linear second wear track 23 (as shown in Figure 7), when the accuracy and smoothness of the second slider 21 are not good, the second slider 21 can be The block 21 is removed from the slide rail 90 , and the second wear track 23 on each slide rail rolling groove 91 of the slide rail 90 does not overlap with the first wear track 13 .

Finally, the slide rail 90 is inserted into the third through hole 311 of the third slide block 31 , and the third ball 32 is located between the slide rail rolling groove 91 of the slide rail 90 and the third end of the third slide block 31 . Slide block groove 312, and this slide rail 90 and this 3rd slide block 31 apply a preload, make this 3rd ball 32 and the slide rail rolling groove 91 inner wall surface of this slide rail 90 and with this first The lowest point contact between the inner walls of the third slider rolling groove 312 of the three sliders 31 (as shown in Figure 6 ), the contact angle is 55 degrees, the third ball 32 is driven by the third slider rolling groove 312, The movement track of the third ball 32 on each slide rail rolling groove 91 of the slide rail 90 falls outside the first wear track 13 and the second wear track 23, so that the accuracy and smoothness of the displacement of the third slide block 31 are not good. Affected.

After the slide rail 90 and the third slide block 31 have been used for a period of time, the inner wall surfaces of the slide rail rolling grooves 91 of the slide rail 90 and the inner wall surfaces of the third slide block rolling grooves 312 of the third slide block 31 , after being worn out by the third ball 32 into a linear third wear track 33 (as shown in Figure 7), when the accuracy and smoothness of the third slider 31 are not good, the slide rail 90 can be moved to the The third slide rail 30 is removed, and a new set of linear slide rail sets 100 is replaced, and the third wear track 33 on each slide rail rolling groove 91 of the slide rail 90 is not in contact with the first wear track 13 and Overlaps this second wear track 23 .

Therefore, in the present invention, the contact angle of the first slider 11 is 35 degrees, the contact angle of the second slider 21 is 45 degrees, and the contact angle of the third slider 30 is 55 degrees. The contact angles of the second and third sliders 11, 21, and 31 are all different, and the first wear track 13, the second wear track 23 and the third wear track 33 can be worn out on the slide rail 90 respectively, and the first wear track 13. The second wear track 23 and the third wear track 33 do not overlap. Therefore, the slide rail 90 in the present invention can be used in conjunction with the first slider 11 and the first ball 12, the second slider 21 and the second ball 22, and the third slider 31 and the third ball 32 respectively, neither Affecting the positioning accuracy can prolong the service life of the slide rail 90 to three times, so as to greatly reduce the maintenance cost for replacing the slide rail 90 .

Among them, the number of times the slide rail 90 of the linear slide rail group 100 can be reused depends on the needs of the working environment. It is used in conjunction with the slide rail 90 sequentially.

Referring to Fig. 8 to Fig. 12, a linear slide rail set 200 is provided for the second preferred embodiment of the present invention, which includes a slide rail 90, a first slider 11, a plurality of first Ball 12, a second slide block 21, some second balls 22, a third slide block 31 and some third balls 32, the main difference between the two is:
