Description

[0001] The present application relates to the field of precision machinery and hydrostatic pressure technology, and particularly to a novel composite throttler and a high-rigidity anti-overturning hydrostatic guide rail structure. BACKGROUND

[0002] The conventional hydrostatic guide rail test platform usually adopts a single sliding block, which is prone to failure when subjected to overturning torque, resulting in a significant reduction in linear motion precision. The conventional throttler is usually designed in an integrated manner, which is prone to blockage and difficult to maintain in a harsh working environment, thereby reducing the service life. The conventional thin-film feedback throttler uses a single throttling mode, which has low throttling efficiency and poor adjustment capacity. In an environment with large load variation, the conventional thin-film feedback throttler has slow adjustment speed, thereby resulting in poor guide rail rigidity performance. SUMMARY

[0023] The inner part of the inner cover plate 6 is respectively provided with a first oil inlet flow channel 11, a first oil outlet flow channel 12 and a second oil outlet flow channel 13, one side of the elastic film 10 is provided with a first connecting hole 14, the central position of the first small hole throttling piece 8 is provided with a first throttling hole 15, one side of the first small hole throttling piece 8 is provided with a first oil outlet hole 16, one end of the first oil inlet flow channel 11 is respectively communicated with the first connecting hole 14 and the first throttling hole 15, the other end of the first oil inlet flow channel 11 is communicated with the oil outlet on the upper part of the side wall of the first static pressure slider 2 or the oil outlet on the upper part of the side wall of the second static pressure slider 3, one end of the first oil outlet flow channel 12 is communicated with the first oil outlet hole 16, the other end of the first oil outlet flow channel 12 is communicated with the oil inlet on the middle part of the side wall of the first static pressure slider 2 or the oil inlet on the middle part of the side wall of the second static pressure slider 3, one end of the second oil outlet flow channel 13 is communicated with the inside of the outer cover plate 7, the other end of the second oil outlet flow channel 13 is communicated with the oil inlet on the lower part of the side wall of the first static pressure slider 2 or the oil inlet on the lower part of the side wall of the second static pressure slider 3.

[0024] The inner part of the outer cover plate 7 is respectively provided with a second oil inlet flow channel 17 and a third oil outlet flow channel 18, the center position of the second small hole throttle piece 9 is provided with a second throttle hole 19, one side of the second small hole throttle piece 9 is provided with a second oil outlet hole 20, one end of the second oil inlet flow channel 17 is communicated with the first connecting hole 14, the other end of the second oil inlet flow channel 17 is communicated with the second throttle hole 19, the other end of the elastic film 10 is provided with a second connecting hole 21, one end of the third oil outlet flow channel 18 is communicated with the second oil outlet hole 20, the other end of the third oil outlet flow channel 18 is communicated with the second connecting hole 21, one end of the second oil outlet flow channel 13 is communicated with the second connecting hole 21.

[0025] The working principle of the throttle 4 is that the hydraulic oil flows from the first oil inlet flow channel 11 on the upper part of the inner cover plate 6, is branched in the inner part of the inner cover plate 6, one part reaches the first throttle hole 15 of the first small hole throttle piece 8 to perform first-stage throttling, the other part reaches the second throttle hole 19 of the second small hole throttle piece 9 to perform second-stage throttling, and finally flows back to the inner part of the first static pressure sliding block 2 or the inner part of the second static pressure sliding block 3 through the first oil outlet flow channel 12 and the second oil outlet flow channel 13 respectively, and then flows out to each oil cavity surface through the oil outlet of the side wall of the first static pressure sliding block 2 or the oil outlet of the side wall of the second static pressure sliding block 3.

[0026] The hydraulic oil flowing through one side of the inner cover plate 6 of the throttle is directly communicated with the lower load oil cavity of the first static pressure sliding block 2 or the second static pressure sliding block 3 through the corresponding first oil outlet flow channel 12, and this part of oil liquid constitutes the actual oil supply of the lower oil cavity, and its pressure state changes synchronously with the load of the lower oil cavity.

[0027] The hydraulic oil flowing through one side of the outer cover plate 7 of the throttle is communicated with the upper load oil cavity of the first static pressure sliding block 2 or the second static pressure sliding block 3 through the second oil outlet flow channel 13, and this part of oil liquid constitutes the actual oil supply of the upper oil cavity, and its pressure state changes with the change of the working condition of the upper oil cavity.

[0028] Therefore, the upper and lower oil cavities are not shared by the same pressure source, but are independently supplied by different flow paths in the throttle.

[0029] The elastic film 10 arranged between the inner cover plate 6 and the outer cover plate 7 effectively isolates the oil pressure corresponding to the upper and lower oil cavities, and at the same time serves as a sensitive element for pressure feedback adjustment. When the external load or overturning moment acts on the guide rail system, the pressure in the upper and lower oil cavities will be different, and the pressure difference will act on both sides of the elastic film 10, causing the elastic film 10 to deform elastically under the action of the pressure difference. The deformation of the elastic film 10 will cause the change of the throttling gap or the equivalent liquid resistance, thereby adaptively adjusting the oil flow and pressure distribution flowing through the throttle.

[0030] The first pressure sensor 22 is installed at the end of the first static pressure slider 2 away from each other, which is used to detect the actual load oil cavity surface pressure value of the first static pressure slider 2. The four first pressure sensors 22 detect the pressure values on the upper side, lower side, left side and right side of the first static pressure slider 2 respectively. The position where the first pressure sensor 22 is installed at the end of the first static pressure slider 2 close to each other is installed with a plug.

[0031] The first static pressure slider 2 arranged on the left side in the guide rail main platform 1 mainly bears the basic load and multi-degree-of-freedom constraint of the guide rail system. It forms a stable static pressure oil film through the upper and lower, left and right load oil cavities, effectively limits the movement of the first static pressure slider 2 in the vertical direction, horizontal direction and pitch and roll direction, and thus provides high stiffness basic support for the guide rail system.

[0032] The second pressure sensor 23 is installed at one end of the second static pressure slider 3 at the rear end, which is used to detect the actual load oil cavity surface pressure value of the second static pressure slider 3. The two second pressure sensors 23 detect the pressure values on the upper side and lower side of the second static pressure slider 3 respectively. The position where the second pressure sensor 23 is installed at the second static pressure slider 3 at the front end is installed with a plug.

[0033] The second static pressure slider 3 arranged on the right side in the guide rail main platform 1 is arranged at a distance from the first static pressure slider 2 along the length direction of the guide rail main platform 1. The second static pressure slider 3 is provided with upper and lower load oil cavity surfaces. When the guide rail system is subjected to external load or overturning moment, the pressures of the upper and lower oil cavities of the second static pressure slider 3 will change with the load, and a pair of support forces in opposite directions will be formed between the upper and lower oil cavities. Due to the effective force arm between the second static pressure slider 3 and the first static pressure slider 2, the pair of support forces can form a counteracting moment in the guide rail system to resist overturning, thereby significantly improving the anti-overturning ability of the overall structure.

[0034] The first static pressure slider 2 and the second static pressure slider 3 are connected by a screw rod and an oil inlet plate 24. The oil inlet plate 24 is used to inject hydraulic oil into the first static pressure slider 2 and the second static pressure slider 3. The bottom surface of the oil inlet plate 24 is in contact with the top surface of the first static pressure slider 2 on the left side. The bottom surface of the oil inlet plate 24 is in contact with the top surface of the second static pressure slider 3 on the right side. The side wall of the oil inlet plate 24 is provided with an oil inlet connected with the external oil circuit. The bottom surface of the oil inlet plate 24 is provided with an oil outlet on both sides. The top surface of the first static pressure slider 2 and the second static pressure slider 3 is provided with an oil inlet. The oil outlet on the left side of the bottom surface of the oil inlet plate 24 is connected with the oil inlet on the top surface of the first static pressure slider 2. The oil outlet on the right side of the bottom surface of the oil inlet plate 24 is connected with the oil inlet on the top surface of the second static pressure slider 3.

[0035] The mutual cooperation of the constraint effect of the first static pressure slide block 2 on the multiple degrees of freedom and the anti-overturning moment formed by the second static pressure slide block 3 at the far end realizes high rigidity support and stable operation of the guide rail system under high load and eccentric load working conditions without significantly increasing the structure size, and avoids the problem that the traditional single slide block static pressure guide rail is easy to lose stability under the action of the overturning moment.

[0036] The top surface of the guide rail main platform 1 is connected with upper cover plates 25 on the left and right sides through screw rods, the upper cover plate 25 on the left side is used for forming an oil film with a certain rigidity between the first static pressure slide block 2 and the hydraulic oil, so as to avoid upward deviation of the first static pressure slide block 2, and the upper cover plate 25 on the right side is used for forming an oil film with a certain rigidity between the second static pressure slide block 3 and the hydraulic oil, so as to avoid deviation of the second static pressure slide block 3.

[0037] The high-pressure hydraulic oil enters the load oil cavity of the first static pressure slide block 2 and the second static pressure slide block 3 through the throttle, and a stable static pressure oil film is formed between the first static pressure slide block 2, the second static pressure slide block 3 and the guide rail main platform 1, the upper cover plate 25 and the side pressure plate 5, which completely isolates each relative motion part in the bearing state and makes it in a non-contact suspension state, and the support force, guiding force and constraint force borne by the first static pressure slide block 2 and the second static pressure slide block 3 are all derived from the pressure distribution inside the static pressure oil film, rather than the direct contact between solid parts.

[0038] The buffer mechanism includes a mounting plate 26 and a buffer bolt 27, the mounting plate 26 is connected with the end of the side pressure plate 5 through a screw rod, the buffer bolt 27 penetrates the other end of the mounting plate 26, and a rubber buffer head 28 is arranged on the end of the buffer bolt 27 close to the second static pressure slide block 3.

[0039] Working principle: The external high-pressure hydraulic oil is connected through the oil inlet of the side wall of the oil inlet plate 24, and flows into the two first static pressure slide blocks 2 on the left side and the two second static pressure slide blocks 3 on the right side in the guide rail main platform 1 through the oil outlets on the left and right sides of the bottom surface of the oil inlet plate 24 respectively; The hydraulic oil enters the first static pressure slider 2 and the second static pressure slider 3, and then flows into the throttle 4 connected thereto: the oil flows into and is divided from the first oil inlet flow channel 11 of the inner cover plate 6 of the throttle 4, one way through the first throttling hole 15 of the first small hole throttling piece 8 to complete the first throttling, and the oil after the first throttling flows back to the first static pressure slider 2 or the second static pressure slider 3 through the first oil outlet flow channel 12, the other way through the first connecting hole 14 of the elastic film 10 into the second oil inlet flow channel 17 of the outer cover plate 7, and through the second throttling hole 19 of the second small hole throttling piece 9 to complete the second throttling, and the oil after the second throttling flows back to the first static pressure slider 2 or the second static pressure slider 3 through the third oil outlet flow channel 18, the second connecting hole 21 of the elastic film 10 and the second oil outlet flow channel 13, and finally flows out from the corresponding oil outlet of the first static pressure slider 2 or the second static pressure slider 3 to each oil cavity surface to form a supporting oil film to realize the floating and stable movement of the component; During operation, the first pressure sensor 22 detects the load oil cavity pressure on the upper side, lower side, left side and right side of the first static pressure slider 2 in real time, and the second pressure sensor 23 detects the load oil cavity pressure on the upper side and lower side of the second static pressure slider 3, so as to ensure the adjustment accuracy through pressure feedback; The upper cover plate 25 and the side pressure plate 5 on the guide rail main platform 1 realize the upper and lower limiting and left and right positioning of the static pressure slider respectively, the buffer mechanism at the end of the side pressure plate 5 buffers the movement impact force through the rubber buffer head 28, the two first static pressure sliders 2 and the two second static pressure sliders 3 are cooperated, and the dynamic adjustment capacity of the composite throttle 4 is combined, so that the overturning moment is effectively resisted, and the high rigidity and linear motion precision of the overall structure are ensured.
