Description

Technical Field

[0001] The utility model relates to the field of linear guide pairs, and specifically, to a silent micro linear guide pair. Background Technique

[0002] Traditional linear guide pairs, such as a rolling linear guide pair disclosed in the utility model with the application number CN201120285563.1, include a guide rail and a slider. The slider is provided with a groove adapted to the cross-sectional shape of the guide rail. The slider is connected to the guide rail through the groove and can move axially along the guide rail. A raceway is provided at the connection between the groove of the slider and the guide rail, and balls are arranged in the raceway. A returner and a return block are respectively fixedly connected to both ends of the slider. A top retainer is fixedly connected at the connection between the top of the guide rail and the slider, and side retainers are fixedly connected at the connections between both sides of the guide rail and the slider. A ball retainer chain is arranged between the balls, and an oil cup is arranged on the return block. The above technical solution reduces the wear rate of the balls and improves the service life of the balls and the product.

[0003] Currently, the dust-proof requirements for linear guide pairs are relatively high. In the case of a relatively harsh production environment, the service life is not long, dust is easy to enter the raceway, and it is inconvenient to clean the dust entering the guide rail. After long-term use, it is easy to cause wear of the balls, and there will be relatively large noise when the balls contact the guide rail. Currently, it is very easy for some balls not to come into contact with the lubricant in the existing lubricant. A silent micro linear guide pair is needed to solve this problem. Content of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solution: A silent micro linear guide pair includes a guide rail, a first slider is slidably connected to the guide rail. First connection parts and second connection parts are respectively installed at both side ends of the first slider. An oil injection nozzle is installed on the first connection part, an adjustment component is installed on the second connection part, a dust-proof brush is installed on the adjustment component, a retainer is installed inside the first slider, and balls are installed inside the retainer.

[0006] As a preferred technical solution of the utility model, a rotary handle is installed on the adjustment component. A threaded rod is fixedly installed at the bottom end of the rotary handle. The bottom end of the threaded rod is threadedly connected to a threaded groove. The threaded groove is in the middle of a moving block. The bottom end of the moving block is installed with a dust-proof brush.

[0007] As a preferred technical solution of the utility model, second sliders are fixedly installed at both side ends of the moving block. The second sliders are slidably connected to the slide rods at both sides. The bottom ends of the slide rods are fixedly installed with bottom blocks.

[0008] As a preferred technical solution of the present utility model, the threaded rod is threadedly connected to the connecting block, and a slot is provided at the bottom end of the second slider.

[0010] As a preferred technical solution of the present utility model, both the first connecting portion and the second connecting portion are threadedly connected to the first slider through bolts.

[0011] Compared with the prior art, the present utility model has the following beneficial effects:

[0012] (1) The present utility model is a silent micro linear guide pair. The setting of the linear guide pair adjustment component of the device can manually rotate the rotary handle to realize the height adjustment of the dust brush at the bottom end of the moving block.

[0019] Next, with reference to the drawings and specific implementation modes, the utility model will be further described:

[0020] Embodiment 1

[0021] Reference Figure 1 And Figure 3 Referring to FIGS. and, Embodiment 1 includes a guide rail 1, a first slider 2 is slidably connected to the guide rail 1, a first connecting part 3 and a second connecting part 5 are respectively installed at both ends of the first slider 2, a grease nipple 4 is installed on the first connecting part 3, an adjusting assembly is installed on the second connecting part 5, a dust removal brush 8 is installed on the adjusting assembly, a retainer 22 is installed inside the first slider 2. The retainer inside the slider eliminates the friction between the balls 21, enabling the balls 21 to be evenly spaced for movement. The retainer 22 is installed with balls 21. The bottom end of the grease nipple 4 is connected to a diverging pipe 19, and the diverging pipe 19 is connected to the balls 21 through a through hole 20. Both the first connecting part 3 and the second connecting part 5 are threadedly connected to the first slider 2 through bolts 6;

[0022] In this embodiment, the grease nipple 4 is connected to the diverging pipe 19 and diverges to each ball 21, ensuring that the contact ends of the balls 21 and the guide rail 1 can be lubricated with a lubricant, further reducing noise and achieving a silent effect.

[0023] Embodiment 2

[0024] Reference Figure 2 Referring to FIGS. and, this embodiment further describes Embodiment 1. It includes an adjusting assembly, a rotating handle 9 is installed on the adjusting assembly, a threaded rod 11 is fixedly installed at the bottom end of the rotating handle 9, the bottom end of the threaded rod 11 is threadedly connected to a thread groove 14, the thread groove 14 is in the middle of a moving block 12, a dust removal brush 8 is installed at the bottom end of the moving block 12, second sliders 13 are fixedly installed at both ends of the moving block 12, the second sliders 13 are slidably connected to slide bars 16 at both ends, the bottom ends of the slide bars 16 are fixedly installed with bottom blocks 17, the threaded rod 11 is threadedly connected to a connecting block 10, and slots 18 are provided at the bottom ends of the second sliders 13;

[0025] In this embodiment, the height of the dust removal brush 8 is controlled by the adjusting assembly, which also facilitates the cleaning of dust on the guide rail 1 when the second slider 13 is moving.

[0026] In specific applications, an adjustment component is installed on the second connecting part 5 of the linear guide pair provided in this device. By manually rotating the rotating handle 9, the moving block 12 at the bottom end of the threaded rod 11 can be driven to rotate. Since both sides of the moving block 12 are slidably connected to the sliding rod 16 through the second sliders 13, the height adjustment of the moving block 12 can be realized. Moreover, a dust removal brush 8 is installed at the bottom end of the moving block 12. By controlling the height of the dust removal brush 8 through the adjustment component, when the second slider 13 is moving, it is also convenient to clean the dust on the guide rail 1, solving the problem of time-consuming dust cleaning on the guide rail 1. At present, there will be relatively large noise during the use of the linear guide pair. This device connects the oil injection nozzle 4 to the shunt pipe 19 and shunts to each ball 21, ensuring that the contact ends of the balls 21 and the guide rail 1 can be lubricated by the lubricant. In cooperation with the setting of the sound insulation material of the linear guide pair itself, the noise is further reduced to achieve a silent effect, thereby extending the service life of the linear guide pair.
