The variable amplitude part is sealed to the lower part of the upper part and the upper part of the lower part. A hydraulic chamber for holding hydraulic oil is formed between the variable amplitude part, the upper part, and the lower part. The inlet pipe is suitable for supplying hydraulic oil into the hydraulic chamber; The testing mechanism is suitable for testing the pressure inside the hydraulic cavity.

[0024] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] refer to Figures 1 to 2At least one embodiment provides a hydraulically driven variable amplitude guide rail based on hydraulic pressure detection, comprising: a guide rail body 1, which includes an upper part 11 contacting the lower part of the slider, a lower part 12 contacting the mounting position, and a variable amplitude part 13 contacting the side of the slider. The variable amplitude part 13 is sealed to the lower part of the upper part 11 and the upper part of the lower part 12. A hydraulic chamber 17 for holding hydraulic oil is formed between the variable amplitude part 13, the upper part 11, and the lower part 12. Hydraulic oil at a certain pressure is filled into the hydraulic chamber 17 as needed to ensure that the pressure of the variable amplitude part 13 on the side of the slider is maintained at a certain amount, thereby ensuring stable operation of the slider; an inlet pipe 2, which is adapted to supply hydraulic oil into the hydraulic chamber 17; and a detection mechanism 3, which is adapted to detect the pressure in the hydraulic chamber 17. Both the inlet pipe 2 and the detection mechanism 3 are connected to an external control system. When the external control system supplies hydraulic oil to the inlet pipe 2, the hydraulic chamber 17 detects the pressure in the hydraulic chamber 17 and transmits signals to the external control system.

[0026] In some embodiments, the amplitude-changing portion 13 is in sliding contact with both the upper portion 11 and the lower portion 12 to ensure that the width of the amplitude-changing portion 13 can be adjusted; the cross-section of the amplitude-changing portion 13 is rectangular.

[0027] In some embodiments, the amplitude-changing part 13 includes two side parts 14 that are sealed to the upper part 11 and the lower part 12; a hydraulic chamber 17 is located between the two side parts 14, the upper part 11 and the lower part 12.

[0028] In some embodiments, both ends of the side portion 14 include flanges 18; the two flanges 18 of one side portion 14 are sealed to the two flanges 18 of the other side portion 14.

[0029] In some embodiments, the amplitude-changing part 13 further includes a limiting shaft 16; a guide groove 15 is provided on the side part 14; the limiting shaft 16 is inserted into the guide grooves 15 on both sides to guide the middle part of the side part 14, ensuring that the straightness of the side part 14 is qualified, and to ensure that the overall cross-sectional area of ​​the amplitude-changing part 13 is constant.

[0030] In some embodiments, the limiting shaft 16 and the guide groove 15 are transitionally fitted to ensure that the straightness of the two sides 14 remains good when they approach and move away from each other, and to guide the two sides 14; the guide grooves 15 of the two sides 14 are on the same plane.

[0031] In some embodiments, the inlet pipe 2 is disposed at one of the flanges 18; the inlet pipe 2 is connected to the hydraulic chamber 17.

[0032] In some embodiments, the detection mechanism 3 is disposed at one of the flanges 18; the detection mechanism 3 is connected to the hydraulic chamber 17.

[0033] In some embodiments, the detection mechanism 3 includes an inlet pipe 31 and a hydraulic pressure measuring component 32; the hydraulic pressure measuring component 32 is connected to the hydraulic chamber 17 through the inlet pipe 31 and is used to monitor the pressure in the hydraulic chamber 17 in real time, thereby ensuring that the force on the side of the slider meets the requirements. The model of the hydraulic pressure measuring component 32 is ALKC400D.

[0034] Working principle: The slider is snapped onto the outside of the guide rail 1. At this time, the slider is attached to the upper surface of the upper part 11, and the sides of the slider are separated from the amplitude transformer 13. The external control system introduces hydraulic oil into the hydraulic chamber 17 through the inlet pipe 2. The hydraulic oil accumulates and expands in the hydraulic chamber 17, pushing the two sides 14 away from each other. The two sides 14 slide between the upper part 11 and the lower part 12. At the same time, the sides 14 slide relative to each other along the limiting shaft 16. The hydraulic chamber 17 remains sealed throughout the process. When the pressure inside the hydraulic chamber 17 reaches the preset threshold, the hydraulic pressure measuring component 32 transmits the pressure detection signal to the external control system. The external control system stops supplying oil to the hydraulic chamber 17 through the inlet pipe 2. At this time, the sides 14 are attached to the two sides of the slider, so that the preload of the slider reaches the standard state. The slider slides on the guide rail 1 with moderate tightness. The sides 14 continuously provide support force to the sides of the slider, effectively preventing the slider from shaking. The guide rail 1 can be put into normal use.
