Description

Technical Field

[0001] The utility model relates to the technical field of grinding machines, in particular to a stable and reliable liquid static pressure type numerically controlled horizontal spindle circular table surface grinding machine. Background Art

[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, and a few use other abrasive tools such as oilstones and abrasive belts and free abrasives for processing, such as honing machines, super finishing machines, belt grinders, grinders and polishing machines.

[0003] According to a stable and reliable liquid hydrostatic CNC horizontal spindle rotary table surface grinder proposed with announcement number CN215317520U, the application proposes that the inner cavity of the liquid hydrostatic grinding head mechanism is always filled with sufficient oil when working, so that the spindle has good rotation accuracy, and always remains stable and reliable within a larger speed and load range. The spindle bearing system has good rigidity and strength, and works stably and reliably, effectively reducing temperature rise. However, the application uses two clamping plates to clamp the cylindrical workpiece, and the cylindrical workpiece will inevitably shake during the processing; for this reason, we provide a stable and reliable liquid hydrostatic CNC horizontal spindle rotary table surface grinder to solve the above problems. Utility Model Content

[0007] Furthermore, a hydraulic push rod is fixedly connected to the upper surface of the bottom bin, a mounting plate is fixedly connected to the top of the hydraulic push rod, a rotating motor is mounted on the top of the mounting plate, and a grinding wheel body is fixedly connected to the output shaft of the rotating motor.
