Hydrodynamic suspension polishing device based on hydraulic mechanism

Abstract

The invention discloses a hydrodynamic suspension polishing device based on a hydraulic mechanism. The hydrodynamic suspension polishing device comprises a lifting assembly and a polishing assembly, wherein the lifting assembly comprises a base, a rolling guide rail, a sliding shaft sleeve, a ball screw, a coupler, a middle supporting plate, an upper cover plate and a stepping motor; the polishing assembly comprises a polishing tool disc, a polishing solution container, a second coupler, a ball spline shaft, a fixed plate, a guide column, a movable plate, a micro hydraulic cylinder, a hydraulic pump, a belt wheel, a synchronous belt and a servo motor. The hydrodynamic suspension polishing device has the following advantages: the hydraulic mechanism is adopted to overcome the self-weight of the polishing assembly so as to realize the purpose that hydrodynamic pressure suspends a polishing disc during the polishing process; polishing solution is adopted to immerse a polishing tool and the immersion liquid environment of workpieces so as to weaken the negative effect caused by friction heat during the polishing process; the servo motor directly drives the polishing tool disc through the belt wheel to avoid the error accumulation caused by the complicated transmission link and improve the processing precision.

Description

technical field [0001] The invention relates to the field of polishing, and proposes a hydraulic suspension polishing device based on a hydraulic mechanism, which is mainly used in the fields of machinery, optics, electronics and the like. Background technique [0002] Ultra-precision machining is necessary to achieve high shape accuracy, surface accuracy and surface integrity. With the increasing requirements for product quality and diversification, more and higher requirements are put forward for ultra-precision machining. Ultra-precision polishing is currently the most important means of final processing. [0003] Currently, non-contact polishing is the main polishing method to obtain ultra-smooth surfaces. Non-contact polishing means that the workpiece and the polishing disc do not come into contact during polishing, and only the fine particles in the polishing liquid are used to impact the surface of the workpiece to obtain a good surface shape accuracy of the machine...
