Description

Technical Field

[0001] The utility model relates to the technical field of a novel linear guide rail, in particular to a novel linear guide rail. Background Art

[0002] Linear guides are generally used in mechanical devices, transmission systems and other mechanisms. In mechanical devices or transmission systems, some parts need to move linearly to change their positions. In this case, linear guides can play a better role in guiding the movement of parts. Linear guides can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. They are used to support and guide moving parts to make reciprocating linear motion in a given direction. Depending on the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides and other types.

[0003] The existing device has the following shortcomings when in use: the linear guide rail will wear out after being used for a period of time, the distance between the roller and the slide rail groove is too large to be precisely matched, which easily causes the linear guide rail to shake during operation, thereby affecting the smoothness of the track operation, and the roller cannot be adjusted up and down to adapt to the slide rail grooves of different heights opened on the guide rail, so it is not very practical. Utility Model Content

[0004] The purpose of the utility model is to provide a novel linear guide rail to solve the problems raised in the above background technology.

[0006] By adopting the above technical scheme, the threaded rod rotates through the threaded hole A opened on the slider assembly A and the threaded hole B opened on the slider assembly B, so that the slider assembly A and the slider assembly B are assembled into a slider assembly and installed on the linear guide rail. The rollers installed on the slider assembly A and the slider assembly B move on the slide rail groove set on the linear guide rail. When the linear guide rail is worn after being used for a period of time, the threaded rod is driven to rotate by rotating the rotating ring installed on one end of the threaded rod clockwise. Because the threaded rod is threadedly connected with the threaded hole A and the threaded hole B, the slider assembly A and the slider assembly B are relatively moved, driving the roller to move toward the slide rail groove. By adjusting the movement of the roller, the problem of excessive distance between the roller and the slide rail groove when the track is worn and unable to accurately match and easily shake is avoided, thereby improving the stability of the track operation. By rotating one end of the lead screw forward and backward, because the lead screw is threadedly connected with the screw hole opened on the slider assembly A, the lead screw moves up and down to cooperate with the connecting block, driving the roller to move up and down, and the roller can be adjusted up and down to adapt to the slide rail grooves of different heights opened on the guide rail, thereby improving the practicality of the track slider.

[0007] Preferably, the slider assembly A is provided with an auxiliary slide groove, the slider assembly B is provided with an auxiliary plate, and the auxiliary plate is slidably connected to the auxiliary slide groove.

[0008] By adopting the above technical solution, the auxiliary plate is slidably connected with the auxiliary slide groove, so that the slider assembly A and the slider assembly B can be easily assembled.

[0009] Preferably, a slide rail groove is provided on the linear guide rail.

[0010] By adopting the above technical solution, the roller is slidably connected with the slide rail wall in the slide rail groove.

[0011] Preferably, the slider assembly A and the slider assembly B are both equipped with rollers and roller adjustment structures.

[0012] By adopting the above technical solution, the rollers on the slider assembly A and the slider assembly B are adjusted up and down respectively through the roller adjustment structure.

[0013] Preferably, a base is installed at the bottom of the linear guide rail, and bolts are installed on the base.

[0014] By adopting the above technical solution, the linear guide rail is fixed in the working position by bolts on the base.

[0015] Preferably, the slider installed on the connecting block is slidably connected to a sliding groove opened on the inner wall of the slider assembly A.

[0016] By adopting the above technical solution, the stability of the connecting block when it moves up and down is ensured.

[0017] Preferably, the threaded hole A provided on the slider assembly A and the threaded hole B provided on the slider assembly B are aligned.

[0018] Compared with the prior art, the beneficial effects of the utility model are: by adjusting the movement of the roller, the problem of the distance between the roller and the slide rail groove being too large and unable to precisely match and easily shaking when the track is worn is avoided, thereby improving the smoothness of the track operation, and being able to adjust the roller up and down to adapt to the slide rail grooves of different heights opened on the guide rail, thereby improving the practicality of the track slider.

When the linear guide is worn after being used for a period of time, the rotating ring 7 installed on one end of the threaded rod 6 is rotated clockwise to drive the threaded rod 6 to rotate. Because the threaded rod 6 is threadedly connected with the threaded hole A5 and the threaded hole B13, the slider assembly A4 and the slider assembly B12 are relatively moved, driving the roller 8 to move toward the slide rail groove 3. By adjusting the movement of the roller 8, the problem of excessive distance between the roller 8 and the slide rail groove 3 when the track is worn and unable to accurately match and easily shake is avoided, thereby improving the stability of the track operation. By rotating one end of the screw rod 9 forwards and reversely, because the screw rod 9 is threadedly connected with the screw hole 15 opened on the slider assembly A4, the screw rod 9 moves up and down to cooperate with the connecting block 10, driving the roller 8 to move up and down, and the roller 8 can be adjusted up and down to adapt to the slide rail grooves of different heights opened on the guide rail, thereby improving the practicality of the track slider.

[0026] Reference Figure 1 , Figure 2 , Figure 3 The slider assembly A4 is provided with an auxiliary slide groove 11, and the slider assembly B12 is installed with an auxiliary plate 14. The auxiliary plate 14 is slidably connected to the auxiliary slide groove 11. The auxiliary plate 14 is slidably connected to the auxiliary slide groove 11, which facilitates the combined assembly of the slider assembly A4 and the slider assembly B12. The linear guide rail 1 is provided with a slide rail groove 3, and the roller 8 is slidably connected to the slide rail wall in the slide rail groove 3. The slider assembly A4 and the slider assembly B12 are both installed with rollers 8 and roller adjustment structures, and the rollers 8 on the slider assembly A4 and the slider assembly B12 are adjusted up and down respectively through the roller adjustment structure.

[0027] Reference Figure 2 , Figure 3 , Figure 4A base 2 is installed at the bottom of the linear guide 1, and bolts are installed on the base 2. The linear guide 1 is fixed in the working position by the bolts on the base 2. The slider installed on the connecting block 10 is slidably connected with the slide groove opened on the inner wall of the slider assembly A4, ensuring the stability of the connecting block 10 when moving up and down. The threaded hole A5 opened on the slider assembly A4 is aligned with the threaded hole B13 opened on the slider assembly B12.

[0028] The implementation principle of a novel linear guide rail in the embodiment of the present application is as follows: the linear guide rail 1 is fixed in the working position by bolts on the base 2, and the threaded rod 6 is rotated to pass through the threaded hole A5 opened on the slider assembly A4 and the threaded hole B13 opened on the slider assembly B12, so that the slider assembly A4 and the slider assembly B12 are assembled into a slider assembly and installed on the linear guide rail 1, and the roller 8 installed on the slider assembly A4 and the slider assembly B12 moves on the slide rail groove 3 set on the linear guide rail 1. When the linear guide rail is worn after being used for a period of time, the threaded rod 6 is driven to rotate by rotating the rotating ring 7 installed at one end of the threaded rod 6 clockwise, because the threaded rod 6 and the threaded hole A5 is threadedly connected with the threaded hole B13, so that the slider assembly A4 and the slider assembly B12 move relative to each other, driving the roller 8 to move toward the slide rail groove 3. By adjusting the movement of the roller 8, the problem of excessive distance between the roller 8 and the slide rail groove 3, which cannot be precisely matched and is prone to shaking when the track is worn, is avoided, thereby improving the stability of the track operation. By rotating one end of the screw rod 9 forwards and reversely, because the screw rod 9 is threadedly connected with the screw hole 15 opened on the slider assembly A4, the screw rod 9 moves up and down to cooperate with the connecting block 10, driving the roller 8 to move up and down, and the roller 8 can be adjusted up and down to adapt to the slide rail grooves of different heights opened on the guide rail, thereby improving the practicality of the track slider.
