Description
Technical Field
[0001] This utility model relates to a hydrostatic turntable support assembly mechanism, belonging to the technical field of hydrostatic turntable equipment. Background Technology
[0002] A hydrostatic rotary table is a high-precision rotary positioning device widely used in precision engineering for manufacturing high-precision equipment. With the development of industrial technology, the requirements for the precision and stability of rotary table equipment are becoming increasingly stringent, necessitating the addition of support components. A search revealed Chinese patent CN218592312U, which discloses a hydrostatic rotary table structure for CNC machine tools. In this patent, a rotating limiting plate is used, allowing the detector to be positioned at different locations above the hydrostatic rotary table. After the servo motor is activated, it drives the drive gear to rotate, which in turn drives the rack to move. Because the drive rack engages with the limiting strip, the limiting strip moves accordingly, enabling the detector to perform a lateral scan on the upper surface of the hydrostatic rotary table, thus achieving comprehensive detection of the surface. However, the hydrostatic rotary table in this patent is fixed to the CNC machine tool and cannot move vertically. Summary of the Invention
