Chain holder for moving guide

The present invention relates to a chain holder for a mobile guiding device, in particular to a load rail and a no-load rail for a mobile guiding device (also called a linear slider) for maintaining a rolling body in a load rail. Improved with a chain holder that operates in an unloaded track arrangement.

Referring to FIG. 1, the present mobile guiding device 20 (also referred to as a linear slider) is provided for slidingly disposed on a linear slide 40, and is disposed by the internal load track of the moving guide 20 and the unloaded track 202. A plurality of rolling bodies 30 (shown in FIGS. 2 and 3) cause the rolling bodies 30 to roll on the linear slide rails 40, thereby achieving the function of the moving guide 20 sliding on the linear slide rails 40 with low frictional resistance characteristics. Such a moving guide 20 is often used in the field of precision machinery.

Referring again to FIGS. 2 and 3, the structure of the load rail and the unloaded rail 202 of the present mobile guiding device 20 is divided into two parts, one is a main rail for the rolling body 30 to operate, and the other is to provide a chain holder. 10 sliding guide grooves 203 formed on both sides of the load rail and the unloaded rail 202, so that a bendable chain retainer 10 can be disposed on the load rail and the unloaded rail 202. The two side edges 102 of the chain belt holder 10 are slidably disposed in the guiding groove 203, and the rolling elements 30 are disposed in the receiving portion of the chain belt holder 10. 101, the chain holder 10 is slid together with the rolling bodies 30 in the load rail and the unloaded rail 202 (when the moving guide 20 moves on the linear rail 40).

However, the guiding groove 203 is small, so that the chain holder 10 is embedded in the side 102 of the guiding groove 203, and is easily caught in the seam between the moving guiding device 20 and the two-end circulator 201 when sliding. A, lightly causes the mobile guiding device 20 to not smoothly slip, and the chain chain retainer 10 is broken more severely. Therefore, how to overcome the problems occurring in the operation of the above-mentioned conventional chain belt holder is a technique that is actively disclosed in the present invention.

The purpose of the present invention is to provide a chain holder for a mobile guiding device, thereby achieving the purpose of smooth operation of the chain holder.

In order to achieve the above object, the chain holder for the mobile guiding device is used for causing a plurality of rolling bodies inside a moving guiding device to be guided by the limit of the chain holder, so that the rolling body does not The load rails inside the mobile guiding device are separated from the unloaded rails or collided with each other. The preferred technical solution comprises: a strip-shaped flexible strip body; a plurality of side by side are formed on the flexible strip body a rolling body accommodating portion for accommodating a rolling body; and a guiding body respectively disposed at two ends of the flexible tape body, the guiding body having a diameter larger than the flexible body The thickness of the belt body is less than or equal to the diameter of the rolling body.

The chain holder for the movement guiding device further includes a rolling body holding portion between the rolling element accommodating portions for restricting the rolling body from being located in the rolling body accommodating portion. .

In the chain holder for the above-described movement guide device, the flexible belt body, the rolling element accommodation portion, the rolling element holding portion, and the guide body are integrally molded by plastic injection molding.

In the chain holder for the above-described moving guide device, the rolling body is a circular roller, and the guiding body is the same cylinder as the roller.

In the chain holder for the above-described moving guide device, the rolling element is a circular ball, and the guiding body is the same spherical body as the ball.

In the above-mentioned chain guide for a moving guide device, the flexible belt body includes two parallel guide strips; the rolling element holding portion is a block connected between the two guide strips, in the two strips The rolling element receiving portion is formed between the guiding strip and each of the rolling element holding portions; and the guiding body is located at an end between the two guiding strips.

In the chain holder for the moving guide device, one end of the rolling element holding portion and a pair of side surfaces adjacent to the rolling body receiving portion respectively form a blocking convex portion, and the stopping convex portion has a rolling The curved surface of the body contact.

The chain holder for the present mobile guiding device uses the guiding body at the two ends of the flexible belt body to be disposed on the load rail and the unloaded rail inside the moving guiding device, so that when the moving guiding device slides and is arranged in a straight line On the slide rail, when the rolling body is supported to roll on the linear slide rail, the flexible belt body can be guided to move by the guide body, and the guide rails on both sides can be restrained from running around when the chain belt is running. 100% cross the track joint without the occurrence of a snapping, avoiding the guide strips on the two sides being stuck and broken in the guiding grooves of the load rail and the unloaded rail, so that the chain retainer can run smoothly. efficacy.
