Roller assembly for a guide rail guard

Abstract

This utility model discloses a roller accessory for a guide rail protective cover, belonging to the technical field of protective cover technology. It includes a mounting plate with two connecting feet fixedly connected to its bottom end. Each connecting foot has a rotating hole, and a shaft is rotatably connected within these holes. A roller assembly is fixedly connected to the circumferential surface of the shaft, and the roller assembly is located between the lower side of the mounting plate and the two connecting feet. In this utility model, the mounting plate is connected inside the guide rail protective cover, and both ends of the shaft are rotatably connected to the two rotating holes on the connecting feet. When the protective cover extends or retracts on the guide rail, the roller assembly contacts the guide rail and rolls. During the rolling process, the rolling force is always concentrated at the rotating connection point between the shaft and the two connecting feet, thus ensuring stable rolling regardless of the width of the rollers. This guarantees the extension and retraction effect of the guide rail protective cover and avoids wear caused by direct friction between the non-rotating rollers and the guide rail.

Description

Technical Field

[0001] This utility model relates to the field of protective cover technology, and more specifically, to a roller accessory for a guide rail protective cover. Background Technology

[0002] Guide rail protective covers are devices used to protect machine tool guide rails. They can protect the internal hard guide rails, linear guide rails, ball screws, or transmission racks of machine tools from external corrosion and damage. They are widely used in various machine tool equipment. Among them, the most common guide rail protective cover is the accordion type. The accordion type guide rail protective cover is a flexible protective cover that can be folded and protects the exposed guide rails by means of telescoping.

[0003] Currently, to improve the smoothness of expansion and contraction, accordion-style guide rail protective covers typically incorporate internal roller components that contact the guide rail. These roller components help reduce friction, making the protective cover expand and contract more smoothly, thereby improving the equipment's operating efficiency and stability. Existing roller components involve rotating the rollers onto a shaft, with the rollers contacting the guide rail surface and rolling along the guide rail as the protective cover expands and contracts. However, the force on the rollers is distributed according to their width. Since most guide rail surfaces are typically quite smooth, this force distribution causes the rollers to not rotate and instead rub directly against the guide rail. This not only affects the expansion and contraction effect of the guide rail protective cover but also causes wear on the guide rail and rollers. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a roller accessory for a guide rail protective cover. The aim is to solve the problem that in the prior art, roller accessories are mounted on a shaft with the roller rotating. The roller contacts the guide rail surface and rolls on the guide rail as the protective cover extends and retracts. However, the force on the roller is dispersed according to its width. Since most guide rail surfaces are usually quite smooth, this force dispersion causes the roller to not rotate and instead rub directly against the guide rail. This not only affects the extension and retraction effect of the guide rail protective cover but also causes wear on the guide rail and the roller.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] A roller accessory for a guide rail protective cover includes a mounting plate. Two connecting feet are fixedly connected to the bottom end of the mounting plate. Each of the two connecting feet has a rotating hole. A shaft is rotatably connected in the two rotating holes. A roller assembly is fixedly connected to the circumferential surface of the shaft, and the roller assembly is located on the lower side of the mounting plate and between the two connecting feet.

[0009] As a preferred embodiment of this utility model, the bottom ends of the two connecting feet are provided with locking holes, and the two locking holes are respectively connected to the two rotating holes and correspond to the shaft.

[0010] As a preferred embodiment of this utility model, the upper part of the mounting plate is provided with a snap-fit ​​groove, and the upper part of the mounting plate is fixedly connected with an elastic buckle, and the elastic buckle is located in the snap-fit ​​groove.

[0011] As a preferred embodiment of this utility model, the mounting plate has a through hole, and the through hole communicates with the snap-fit ​​groove.

[0012] 3. Beneficial effects

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) In this scheme, the mounting plate is connected inside the guide rail protective cover, and the two ends of the shaft are rotatably connected to the two rotating holes opened by the two connecting feet. When the protective cover extends and retracts on the guide rail, the roller group contacts the guide rail and rolls. During the rolling process, the rolling force is always concentrated at the rotating connection between the shaft and the two connecting feet, so that the roller can maintain stable rolling regardless of its width, ensuring the extension and retraction effect of the guide rail protective cover and avoiding wear caused by the roller not rotating and directly rubbing against the guide rail.

[0023] Please see Figure 1-3 A roller accessory for a guide rail protective cover includes a mounting plate 1. Two connecting feet 2 are fixedly connected to the bottom end of the mounting plate 1. Each connecting foot 2 has a rotating hole 3. A shaft 4 is rotatably connected in the two rotating holes 3. A roller assembly 5 is fixedly connected to the circumferential surface of the shaft 4, and the roller assembly 5 is located between the lower side of the mounting plate 1 and the two connecting feet 2.

[0024] In this embodiment, the roller assembly 5 is fixed on the shaft 4. The shaft 4 is installed in two rotating holes 3 and rotates between two connecting feet 2, so that the two roller assemblies 5 can rotate on the underside of the mounting plate 1. The mounting plate 1 is installed inside the guide rail protective cover, so that the roller assembly 5 contacts the guide rail surface. When the guide rail protective cover extends or retracts, the roller assembly 5 slides on the guide rail surface following the extension or retraction of the protective cover, making the extension or retraction of the protective cover smoother.

[0025] Specifically, each of the two connecting feet 2 has a mounting port 6 at its bottom end, and the two mounting ports 6 are connected to the two rotating holes 3 and correspond to the shaft 4.

[0026] In this embodiment, the two connecting feet 2 have a certain degree of elasticity, so that the two mounting holes 6 also have a certain degree of elasticity. The two ends of the shaft 4 are respectively engaged and installed into the two rotating holes 3 through the two elastic mounting holes 6, so that the shaft 4 can be rotated and connected in the two rotating holes 3 opened in the two connecting feet 2.

[0027] Specifically, the upper part of the mounting plate 1 is provided with a snap-fit ​​groove 7, and the upper part of the mounting plate 1 is fixedly connected with an elastic buckle 8, and the elastic buckle 8 is located in the snap-fit ​​groove 7.

[0028] In this embodiment, the mounting piece 1 is snapped into the connection point inside the guide rail protective cover by the snap-fit ​​groove 7. The elastic buckle 8 uses its own elasticity to elastically press and fix the connection part of the guide rail protective cover in the snap-fit ​​groove 7, thereby maintaining a stable connection between the mounting piece 1 and the protective cover. The protective cover drives the roller assembly 5 to roll smoothly on the guide rail through the mounting piece 1.

[0029] Specifically, the mounting plate 1 has a through hole 9, and the through hole 9 is connected to the snap-fit ​​groove 7.

[0030] In this embodiment, after the connection of the protective cover is inserted into the snap-fit ​​groove 7 and fixed, the through hole 9 corresponds to the connection of the protective cover in the snap-fit ​​groove 7. The through hole 9, together with the bolt, can lock and fix the protective cover and the mounting piece 1, further improving the stability of the connection between the protective cover and the mounting piece 1.

[0031] Working principle: The roller assembly 5 is fixed on the circumferential surface of the shaft 4. The two ends of the shaft 4 are respectively inserted into two rotating holes 3 for rotational connection. The shaft 4 and the roller assembly 5 are both located on the lower side of the mounting plate 1. The mounting plate 1 is fixedly connected inside the guide rail protective cover, so that the roller assembly 5 contacts the guide rail surface. When the protective cover extends and retracts on the guide rail, it drives the mounting plate 1 to move. The mounting plate 1 drives the roller assembly 5 and the shaft 4 to move. The roller assembly 5 contacts the guide rail surface and rolls through the shaft 4, so that the protective cover can extend and retract smoothly on the guide rail.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
