Description

Technical Field

[0001] The utility model relates to the technical field of linear slide rails, in particular to a miniature linear guide pair with a wide cross section. Background Art

[0002] The linear guide pair consists of two parts: the guide rail and the slider. The slider includes the slider body, rolling elements, end plastic covers and other components to ensure the cyclic rolling of the rolling elements. When in use, the slider uses the steel balls inside it as the medium to make a linear motion on the guide rail. The linear slider uses the rolling elements as the medium to make a linear motion on the guide rail, which will cause a certain temperature rise and wear, and it needs to be regularly lubricated for maintenance.

[0003] According to a disclosed end plastic cover and linear guide pair (Announcement No.: CN110985539A), in the above application, lubricating oil can be injected into the circulation channel through the oil filling hole. The lubricating oil can fully and stably lubricate the rolling elements, reducing the probability of problems such as temperature rise and wear of the rolling elements when the rolling elements move linearly on the guide rails, thereby reducing the wear between the rolling elements and the guide rails, and improving the service accuracy and life of the linear guide pair.

[0004] However, during the actual use of the above-mentioned equipment, the oil outlet end of the oil outlet hole continuously flows lubricating oil to the track on the ball to lubricate the surface of the ball. Although long-term continuous oil discharge can ensure the continuous lubrication effect of the ball, it will also waste lubricating oil excessively and increase the operating cost of the equipment. In view of this, we propose a wide-section micro linear guide pair. Utility Model Content

[0005] The utility model aims to provide a miniature linear guide pair with a wide cross-section to solve the problems raised in the above-mentioned background technology.

[0014] Compared with the prior art, the utility model provides a wide-section miniature linear guide pair, which has the following beneficial effects:

[0015] 1. The wide-section micro linear guide pair is provided with a lubrication mechanism. Lubricating oil is injected into the oil filling end of the slider body, and discharged through the porous oil outlet to lubricate the track of the guide body, thereby reducing the loss of lubricating oil. The uniform plate further evenly spreads the discharged lubricating oil. During the contact between the uniform plate and the lubricating oil, the lubricating oil generates resistance to the uniform plate. Under the action of the telescopic spring, the uniform plate is slightly shaken, so that the lubricating oil is spread more evenly, saving lubricating oil to a certain extent while ensuring the operation of the ball.

Under the action of the elastic force of the return spring to squeeze the lubricating oil, the subsequent application at the gap position is more even. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In addition, in order to promote the mechanism 4, it includes a collecting plate 401, the surface of the mounting table 302 is slidably connected to the collecting plate 401, and a collecting groove 402 is opened on the surface of the collecting plate 401. The inner wall of the collecting groove 402 is fixedly connected to a reset spring 404, and one end of the reset spring 404 away from the collecting groove 402 is fixedly connected to a movable plate 403, and the shape of the movable plate 403 is adapted to the shape of the collecting groove 402. The widths at both ends of the movable plate 403 are greater than the width in the middle, and the horizontal positions of the two ends of the movable plate 403 are adapted to the horizontal position of the oil outlet 301, so as to collect a certain amount of lubricating oil for smearing on uneven parts.

[0027] In an embodiment of the utility model, the cross-sectional shape of the movable groove 304 is adapted to the cross-sectional shape of the T-block 306, and the cross-sectional shape of the movable groove 304 is larger than the cross-sectional shape of the T-block 306, so that the T-block 306 can slightly shake inside the movable groove 304, and the number of telescopic springs 305 is set to be several, and the several telescopic springs 305 are fixedly installed in a circular array on the outer sides of both ends of the T-block 306, and the number of collecting plates 401 is set to two groups, and the collecting plates 401 and the uniform plates 303 are on the same horizontal line, and the uniform plates 303 are arranged between the collecting plates 401 and the oil outlet 301, and a certain amount of lubricating oil is first collected to apply it to the uneven parts to ensure that the surface of the track 8 is more uniform, and the surface of the dust baffle 7 is provided with an oil filling end to facilitate the injection of lubricating oil, and the oil outlet 301 is positioned against the surface of the track 8 to facilitate lubrication of the surface of the track 8.
