New Description: [New Technology Field] This creation is about a replaceable fluid restrictor, especially the size of the oil passage exit that adjusts and rotates the control rod into and out of the adjustment chamber. , by the outflow of the throttle. [Prior Art] The slipper of the machine tool is the main guiding and supporting mechanism of the moving shaft. The traditional machine tool bearing adopts linear sliding or hard-acting, the linear sliding rail adopts roller or ball transmission, and the hard handle is in contact with the movable part. Applying Turcite wear-resistant sheet to the surface to force lubrication with the slide oil. Both have a certain number of years of use. After using for a period of time, they need to be repaired again, and environmental problems cannot be recovered after using the lubricating oil. In addition, the movement between the table of the conventional machine tool and the track such as the linear slide rail or the hard rail is a mixed friction mechanism, and the frictional force changes greatly, and the backlash problem is also increased, and there is a rubber slip in the low speed movement (Stick). -slip) is generated, which causes the positioning to be inaccurate and needs to be compensated by the controller. At the same time, due to the intermittent forced lubrication of the slide rail during the processing, the work platform has a regular oil-scraping knife mark, but the controller cannot be used. The compensation is improved, especially for the production of lamp molds or high-precision workpieces that require smooth machining surfaces. The machine tool motion platform needs stable motion. At present, the machine tool needs to improve this problem. Therefore, the use of hydrostatic bearing slippery systems will be a good solution. Furthermore, hydrostatic bearings have a large load carrying capacity and are also more widely applicable than linear rails or hard handles. For linear hydrostatic bearing design f, different designs are made according to the needs of use. The main considerations are hydraulic oil supply system and structural design. M330885 hydrostatic bearing is a new type of bearing, T. . . j in contact ball or roller bearing, which has 咼 rigidity, high damping, low wear ^ ^ t inflammation, and nowadays it is used for precision Grinding machine and ultra-precision machine tool. In 1938, the American astronomical telescope rotary table adopts hydrostatic bearing μ, which rotates at a low speed of 1/12 horsepower per day-week. It can be seen that the use of hydrostatic a bearing at low speed load has good performance and can be accurate. Precise positioning. In the early years, the country has made static hydrostatic bearing technology on the grinding machine, which can greatly improve the precision of the grinding machine and the life of the sliding machine, and reduce the maintenance of the machine tool. Since the chest is quiet (four) has begun to use the machine, the hydrostatic (four) bearing _ The team used multi-oil cavity bearing design parameters to obtain the best value of the effective oil seal area under the minimum oil film thickness and friction loss. The pressure of the static pressure oil chamber is a very important part. The surface of the static pressure oil chamber is used to investigate the effects of different oil chamber depths, throttling modes and gap thickness on the pressure distribution. The results show that the injection oil is similar to the orifice restrictor (O Riffice Restrictor) 'There is a lower probability of generating a turbulent vortex in the flow field with a pressure gradient in the cavity when the depth of the oil cavity is shallow. It shows that the orifice throttle and shallow oil cavity design are better than the deep oil cavity without throttling pressure. The dynamic pressure effect. The influence of the capillary hydrocyclone (Capi 1 iary Restrict〇r) on the static and dynamic characteristics of the static hydrostatic slide is mainly studied in the research of the hydrostatic bearing. It can be seen that reducing the capillary diameter can obtain better bearing capacity and oil film rigidity, and can be used in a machine tool to improve the displacement accuracy.

When the plurality of oil pipes are connected to the throttle body (2), the oil entering from the hydraulic oil inlet (22) is caused by the distribution groove (31) of the adjusting rod (3). The oil passage outlet (23) of the main body of the circumference is a taper surface joint, and the oil outlet (23) of the adjustment chamber (21) is adjusted by adjusting and rotating to adjust the oil outlet (23) to control the outflow of the oil. 8 M330885 “ The plug-in orifice restrictor of the first embodiment is used as the pressure adjustment element day, and the principle of the oil (four) force adjustment is to adjust the oil passage of the adjustment chamber (9) by the rotation control of the adjustment rod (3).

According to the capillary throttling organ of the second embodiment of the present invention, the difference between the capillary restrictor and the plug-in orifice restrictor lies in that the adjusting rod (3) is: the matching groove (31) exhibits a capillary length adjusting characteristic, and The principle uses the thread as the capillary: the diameter 'uses the adjustment rod (3) to adjust the pressure adjustment end (32), the adjustment rod (7) thread is located in the fixed element (1), the longer the spiral path, the greater the pressure drop, otherwise the smaller The principle is used to adjust the pressure in the throttle body (2). When the invention is applied to the slide rail of the machine tool, the sliding system adopts a symmetric hydrostatic bearing structure, and the throttle body (2) is controlled symmetrically. Multi-cavity and special hydraulic circuit design make it self-compensating. In addition, the plug-in orifice restrictor of this creation is the throttle body (2) and the adjusting rod as the inlet pressure and pressure regulating element (3) ),although When the force source is supplied by the hydraulic press (not shown), this creation can adjust multiple pressure modes with a small number of plug-in orifice restrictors, and use the adjusting rod (3) to distribute the flow between the bearing surfaces of the distribution groove (31). It is automatically compensated for the hydraulic pressure.
