Therefore, it is particularly important to develop a linear guide with a precision adjustment function. This kind of guide can achieve fine adjustment of its guiding accuracy through a built-in micro-adjustment mechanism or by using special materials and designs, so as to compensate for the accuracy deviation caused by long-term operation or external environmental changes. For example, the fine adjustment of accuracy can be achieved by adjusting screws, using wedge blocks, or by means of magnetism. In addition, this kind of guide is often equipped with highly sensitive sensors to monitor its motion state and position information in real time to ensure precise control of the motion. In the prior art, the adjustment accuracy is low, the stability is poor, and the maintenance is difficult, which needs to be improved. For this reason, we have proposed a linear guide with a precision adjustment function. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.
[0023] Please refer to Figures 1-4 , a linear guide with a precision adjustment function, including a V - groove aluminum alloy 8. One end of the V - groove aluminum alloy 8 is fixed with an end cover 16, and the other end of the V - groove aluminum alloy 8 is fixed with a motor 9. The motor 9 is fixedly connected to a lead screw 15 through a connecting sleeve 11. A fixing block 13 is sleeved on the outer surface of the lead screw 15, and four sliders 2 are movably installed below the fixing block 13.
[0024] Furthermore, the lower surface of the slider 2 is closely fitted with the groove on one side of the lead screw 15. Rectangular grooves are provided on both sides inside the slider 2. Four screw holes are provided on the upper surface of the slider 2. A square slide rail 14 is movably installed inside the slider 2. Four screw holes are provided on both sides of the slider 2. Adjusting bolts 1 4 and adjusting bolts 2 5 are provided on both sides of the slider 2. The adjusting bolt 1 4 is located above the adjusting bolt 2 5. One ends of the adjusting bolt 1 4 and the adjusting bolt 2 5 are movably installed in the grooves on the surface of the adjusting bracket 3.
[0025] Furthermore, a rotating shaft 1 is rotatably installed inside the adjusting bracket 3. An adjusting pulley 6 is sleeved on the outer surface of the rotating shaft 1. The two ends of the rotating shaft 1 do not contact the inner wall of the groove inside the slider 2. The peripheral edge of the adjusting pulley 6 coincides with the edge of the square groove inside the slider 2. The cross - section of the adjusting bracket 3 is trapezoidal, and there is a protrusion on one side of the adjusting bracket 3.
[0026] Furthermore, a grease nipple 7 is provided below the slider 2. There is a hole inside the grease nipple 7, and the hole inside the grease nipple 7 communicates with the square groove inside the slider 2.
[0027] Furthermore, the motor 9 is fixed on one side surface of the motor fixing plate 10. The lower part of the motor fixing plate 10 is fixed above the V-groove aluminum alloy 8. Square slide rails 14 are fixed on both sides of the motor fixing plate 10, and the edges of the square slide rails 14 are rounded.
[0028] Furthermore, the surface of the lead screw 15 is provided with fine threads. The lower part of the end cover 16 is fixed on the upper surface of the V-groove aluminum alloy 8. Square slide rails 14 are fixed on both sides of the end cover 16.
[0029] Furthermore, a flange 12 is movably installed on one side of the fixing block 13. Four sliders 2 are fixed below the fixing block 13 by sixteen hexagon socket head cap screws. One ends of the adjusting bolt 1 4 and the adjusting bolt 2 5 do not contact the outer surface of the fixing block 13.
[0030] Working principle: In this utility model, after the motor 9 is started, it drives the lead screw 15 to rotate through the connecting sleeve 11. The rotation of the lead screw 15 causes the fixing block 13 to move along the axial direction of the lead screw 15. Since the fixing block 13 and the four sliders 2 are fixed by hexagon socket head cap screws, the sliders 2 also move together with the fixing block 13. The lower surface of the slider 2 fits tightly with the groove on one side of the lead screw 15, ensuring the smoothness and accuracy of the movement. When it is necessary to adjust the accuracy of the linear guide rail, it can be achieved by adjusting the adjusting bolt 1 4 and the adjusting bolt 2 5. These two adjusting bolts are installed in the surface grooves of the adjusting bracket 3, and one ends of them cooperate with the internal rectangular grooves of the slider 2. By rotating the adjusting bolt 1 4 and the adjusting bolt 2 5, the position of the slider 2 can be finely adjusted, so as to compensate for the accuracy deviation caused by long-term operation or external environmental changes. In addition, the rotating shaft 1 inside the adjusting bracket 3 and the sleeved adjusting pulley 6 form an adjusting mechanism. The rotation of the rotating shaft 1 can drive the adjusting pulley 6 to move, thereby affecting the position of the slider 2, providing another way of accuracy adjustment. In order to reduce wear and extend the service life, a grease nipple 7 is provided below the slider 2, through which the slider 2 can be lubricated. The structural design of the entire linear guide rail takes into account easy maintainability. For example, the layout of the motor 9 and the motor fixing plate 10 facilitates the maintenance and replacement of the motor 9. At the same time, the V-groove aluminum alloy 8 serves as the main structure of the guide rail, providing stable support. Through such a design, the linear guide rail of this utility model has the characteristics of high adjustment accuracy, good stability, and easy maintenance while ensuring the movement accuracy and repeat positioning accuracy.
[0031] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
