Description

Technical Field

[0001] This utility model relates to the field of guide rail sliders, specifically a dustproof and noise-reducing linear guide rail slider assembly. Background Technology

[0002] With the rapid development of modern industrial technology, linear guide slider assemblies, as crucial transmission components in mechanical equipment, directly affect the overall operating performance of the equipment. Linear guide slider assemblies are widely used in high-precision, high-efficiency industrial fields such as CNC machine tools, semiconductor equipment, and automated production lines to achieve precise linear motion control.

[0003] However, existing linear guide slider assemblies generally suffer from insufficient dustproof and noise reduction performance. In complex and variable industrial environments, especially those with large amounts of dust particles, traditional linear guide slider assemblies are easily intruded by dust. Once these dust particles enter the slider, they accelerate wear between the slider and the guide rail, leading to decreased motion accuracy and shortened service life. Utility Model Content

[0004] The purpose of this invention is to provide a dustproof and noise-reducing linear guide slider assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dustproof and noise-reducing linear guide slider assembly includes a base plate. A mounting component is welded to the front end of the base plate, and a motor is mounted on the front end of the mounting component. A lead screw is fixedly connected to the drive end of the motor. A bearing seat is fixedly connected to the axial center of one end of the base plate near the mounting component. A lead screw cylinder is threaded to the outer wall of the lead screw, and a top plate is fixedly connected to the outer wall of the lead screw cylinder. The top plate includes a sliding groove block. An mounting strip is fixedly connected to the inner wall of the groove block. A semi-arc cylinder is fixedly connected to the outer wall of the mounting strip. An inner groove is fixedly connected to the inner side of the semi-arc cylinder. A ball groove is formed on the outer wall of the inner groove, and a ball is installed at the opening of the ball groove.

[0007] As a further embodiment of this utility model: a bearing component is fixedly connected to the end of the substrate, and the bearing component is rotatably connected to the bottom of the lead screw.

[0008] As a further improvement of this utility model, the number of ball grooves is three sets, and the three sets of ball grooves are respectively opened on the left, right and lower sides of the inner cavity of the semi-arc cylinder.

[0009] As a further improvement of this utility model: the inner frame of the substrate is fixedly connected to slide rails on both the left and right sides, and the slide rails are slidably connected to the slide block.

[0010] As a further improvement of this utility model, the ball groove is arc-shaped, and the opening degree of the ball groove is smaller than the radius of the ball.

[0011] As a further improvement of this utility model: the outer wall of the semi-arc cylinder is provided with an installation groove, and the installation groove is slidably connected to the installation strip.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model controls the operation of a motor, which drives a lead screw to rotate. When the lead screw rotates, it causes the threaded lead screw cylinder to move back and forth. Because the top plate fixed to the outer wall of the lead screw cylinder, together with the sliding block and the slide rails on the left and right sides of the inner frame of the base plate, slides and limits the movement of the lead screw cylinder after the lead screw rotates, ensuring that the lead screw cylinder can only move back and forth when the lead screw is rotating. The mounting strip connected to the inner side of the sliding block, together with the mounting groove, connects the sliding block and the semi-arc cylinder, which is used to fix the semi-arc cylinder to the inner wall of the sliding block to reduce noise. Its structure is more optimized and its design is more reasonable. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4In this embodiment of the present invention, a dustproof and noise-reducing linear guide slider assembly includes a base plate 1. A mounting component 5 is welded to the front end of the base plate 1. A motor 4 is mounted on the front end of the mounting component 5. A lead screw 2 is fixedly connected to the drive end of the motor 4. A bearing seat 3 is fixedly connected to the axial part of one end of the base plate 1 near the mounting component 5. A lead screw cylinder 8 is threadedly connected to the outer wall of the lead screw 2. A top plate 6 is fixedly connected to the outer wall of the lead screw cylinder 8. The top plate 6 includes a sliding groove block 7. An installation strip 15 is fixedly connected to the inner wall of the groove block 7. A semi-arc cylinder 13 is fixedly connected to the outer wall of the installation strip 15. An inner groove 10 is fixedly connected to the inner side of the semi-arc cylinder 13. A ball groove 11 is opened on the outer wall of the inner groove 10. A ball 12 is installed at the groove opening of the ball groove 11.

[0021] A bearing 9 is fixedly connected to the end of the substrate 1, and the bearing 9 is rotatably connected to the bottom of the lead screw 2.

[0022] There are three sets of ball grooves 11, which are respectively opened on the left, right and lower sides of the inner cavity of the semi-arc cylinder 13.

[0023] The inner frame of the substrate 1 is fixedly connected to slide rails on both the left and right sides, and the slide rails are slidably connected to the slide block 7.

[0024] The ball groove 11 is arc-shaped, and the opening degree of the ball groove 11 is smaller than the radius of the ball 12.

[0025] The outer wall of the semi-arc cylinder 13 is provided with an installation groove 14, and the installation groove 14 is slidably connected to the installation strip 15.

[0026] The working principle of this utility model is as follows:

[0027] In use, the control motor 4 operates, driving the lead screw 2 to rotate. When the lead screw 2 rotates, it will drive the threaded lead screw cylinder 8 to move back and forth. Because the top plate 6 fixed on the outer wall of the lead screw cylinder 8 cooperates with the sliding block 7 and slides on the left and right sides of the inner frame of the base plate 1, the lead screw cylinder 8 is limited after the lead screw 2 rotates, ensuring that the lead screw cylinder 8 can only move back and forth when the lead screw 2 is rotating.

[0028] The mounting strip 15 connected to the inner side of the slide block 7 cooperates with the mounting groove 14 to connect the slide block 7 and the semi-arc cylinder 13, which is used to fix the semi-arc cylinder 13 to the inner wall of the slide block 7.

[0029] The ball groove 11 on the inner wall of the semi-arc cylinder 13, together with the ball 12, is used to slide on the slide rail, ensuring the stability of the slide block 7 during the stabilization process.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
