Rolling column connection keeping device

Abstract

The invention is an originally true roller coupling holding device, comprising connecting parts, holding parts and spacing part, where the holding parts are opposite by twos and vertically connected with the connecting parts and the upper and lower ends of the two opposite holding parts are each connected with a spacing part, the spacing parts are paired by twos and arranged between two rollers, the butt side of the spacing part butts against and linearly contacts with the contact rolling surface of the roller and the butt sides of the opposite spacing parts correspond to the axes of the rollers and are located on the two sides of a non-operating contact rolling surface; the junctions of the spacing parts and the holding parts are equipped with rapping allow groove; the invention is convenient to integrated moulding rapping, and quick and mass production, and the butt side of the spacing part avoids the rollers' bad actions, such as deflection, rubbing, collision and jitter in the rolling course.

Description

technical field [0001] The present invention provides a coupling and retaining device for linear components using rollers as rolling elements. The unique design of the spacer is used to produce the effects of easy integral molding and rapid mass production, and can avoid skewed friction and collision of rollers. Make sure the linear slides drive smoothly. Background technique [0002] With the continuous advancement of modern science and technology, due to the continuous development and improvement of precision feed systems, linear slide rail technology and its products have become the most important part of many precision machines. Various linear mechanism products have been widely used in human life, processing In factories and high-tech equipment, although the development of linear slide rail technology is very rapid, users still need continuous improvement of technology, so linear products such as: linear slide rail still have many problems to be developed, and related t...

AI Technical Summary

Problems solved by technology

[0005] 1. In the prior art, the spacer 11 of the chain 12 is directly formed between the rollers 10 by using the roller 10 as the core of the mold. The production technology is very complicated, and the mold size needs to be changed according to different sizes. When it is longer, the number of rollers 10 to be inserted will increase relatively, the time of production operation will become longer, and the difficulty of production will be higher. Therefore, the technical cost of this existing product is higher.

[0006] 2. Since the spacer 11 is directly formed between the rollers 10 by using the roller 10 as the core of the mold, a release agent must be applied between the spacer 11 and the rollers 10 before the spacer 11 is formed, which also causes The problem of complicated production operations and high cost

[0009] 1. In this prior art, the spacer portion 13 of the protruding connecting portion 131 is directly molded between the rollers 10 by using the roller 10 as the core of the mold. The production technology is also complicated, and the mold size also needs to be adjusted according to different chain sizes. When the dimension changes for a long time, the machine will become relatively larger, and the cost and difficulty of production operations will be higher.

[0010] 2. Since the spacer 13 is also directly formed between the rollers 10 by using the roller 10 as the core of the mold, a release agent must be applied between the spacer 13 and the rollers 10 before the spacer 13 is formed. Complicated production operations and cost a lot

[0011] 3. The protruding connecting part 131 of the second prior art is arranged in the center of the contact rolling surface side of the roller 10, and the slider must be processed with a specific guide in the roller groove of the relative roller operation contact part. groove, because the guide groove is not easy to process, so the second prior art still has a higher production cost, and the protruding connecting portion 131 affects the rolling smoothness

[0012] 4. In the second prior art, the spacer 13 still accommodates the rollers 10 with two concave surfaces, and the radius of curvature of the two concave surfaces of the spacer 13 is the same as that of the rollers 10. Fully fitted surface contact also increases the frictional resistance between the roller and the spacer

[0015] 1. Since the second connecting portion 15 is installed on the contact side of the two end surfaces of the roller 10, and the second connecting portion 15 is flush with the operation contact portion of the roller 10, the connecting portion 15 of the third prior art embodiment will affect The operation of the contact parts on both sides of the roller 10 will form the rolling resistance of the roller 10 during operation and easily form contact friction

[0016] 2. In addition, the oblique support portion 14 of the third prior art is a reduced-contraction oblique extension type, so a short spacer portion 16 will only contact the middle portion of the roller 10, since the roller 10 is only held by one side Therefore, the spacer 16 used for holding in the third prior art will easily swing under the cooperation of the inclined support part 14, which will lead to uneven running force

[0017] It can be seen from the above products that the roller system using linear mechanism in the past still cannot maintain stable operation for a long time; in view of the above defects, in today's pursuit of ideals, practicality and progress, it is a goal to strive for improvement.
