The invention discloses a flexible precise grinding operation platform which comprises an XY-axis sliding table used for clamping a workpiece and a grinding head mechanism located above the XY-axis sliding table and moving in the Z-axis direction. The grinding head mechanism comprises a first servo motor, a lead screw, an elastic body stretching out and drawing back in the Z-axis direction and a grinding head installed at the bottom of the elastic body. The first servo motor drives the lead screw to move up and down. The bottom end of the lead screw abuts against the upper end of the elastic body. According to the flexible precise grinding operation platform, the grinding head can achieve flexible contact and constant-pressure floating relative to the workpiece, vibration can be effectively reduced, and the quality of the machined surface of the workpiece and the service life of the grinding head are guaranteed. Due to the fact that the pressure applied to the workpiece by the grinding head depends on the displacement amount of the lead screw and the elastic modulus of the elastic body, the flexible precise grinding operation platform can accurately obtain the pressure applied to the workpiece by the grinding head by controlling and obtaining the rotation angle output outwards by the first servo motor, and technicians can conveniently analyze the grinding and polishing mechanism of the workpiece and materials of the workpiece.
Description
technical field [0001] The invention relates to the field of machining, in particular to a flexible precision grinding operation platform. Background technique [0002] Abrasive belt grinding, as an ideally compatible grinding and polishing method that can achieve flexible smoothness and precise quality control, can obtain good surface quality, improve grinding efficiency and product qualification rate, and has been gradually and successfully applied to Precision grinding of high-performance components such as aero-engine blades and blisks. [0003] However, for the research on the grinding and polishing mechanism of difficult-to-machine materials such as single crystal superalloys, titanium alloys, and composite materials used in the cutting-edge fields of national defense, the currently used CNC abrasive belt grinding machine tools are only suitable for production and processing, not suitable for Based on the research and analysis of the above grinding and polishing mecha...
