Embodiment Construction

[0018] The structure and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that these examples are used to illustrate the present invention and not to limit the scope of the present invention. The implementation conditions used in the examples can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not indicated are usually the conditions in routine experiments.

[0019] see Figure 1 to Figure 4 , the present invention includes a throttle mount 1 and an open washer 4 installed in the throttle mount 1 , a needle gauge 3 , a spring 6 and a left end plug 7 . The throttle mounting base 1 is composed of a throttle mounting hole 11, a top screw mounting hole 12, an oil outlet 13 and an oil inlet passage 14. Coincidentally, the diameter of the restrictor mounting hole where the left end plug 7 is located is greater than ...

Abstract

The invention relates to a needle gauge throttle. The needle gauge throttle comprises a throttle installation seat; a throttle installation hole, jackscrew installation holes, an oil outlet and an oilinlet channel are arranged in the throttle installation seat; the axis of the throttle installation hole is superposed with the axis of the oil outlet; a left end plug, a spring, a needle gauge and an opening washer are sequentially arranged in the throttle installation hole; the oil outlet is arranged on the opening washer side; the needle gauge is cylindrical; the diameter of the needle gauge is smaller than that of the throttle installation hole at the position of the needle gauge; the jackscrew installation holes are arranged on the circumferential surface of the throttle installation hole and communicate with the throttle installation hole; jackscrews are arranged in the jackscrew installation holes; an axial inclination angle of the needle gauge is changed by adjusting the screwingdepth of the jackscrews; and the oil inlet channel communicates with the throttle installation hole. According to the needle gauge throttle, the structure is compact, the performance is excellent, thesize precision of the throttle diameter is high, meanwhile, since the needle gauge is a standard part, the interchangeability is good, the processing cost is greatly reduced compared with a traditional throttle, and the needle gauge is durable in use and strong in corrosion resistance.

Description

technical field [0001] The invention relates to a restrictor for hydrostatic support, in particular to a pin gauge restrictor for hydrostatic support in ultra-precision machine tools. Background technique [0002] Hydrostatic bearings have the advantages of small frictional resistance, long service life, wide speed range, good anti-vibration performance, high precision, and good adaptability, so they are widely used in ultra-precision machine tools. The restrictor is a necessary and very important component in the constant pressure oil supply hydrostatic support system, which plays the role of automatically adjusting the pressure of the oil chamber, so that the constant pressure oil supply hydrostatic support system has the corresponding oil film bearing capacity and oil film stiffness . Commonly used restrictors mainly include fixed restrictors and variable restrictors. Although the variable restrictor can make the static stiffness of the support reach infinity through re...
