Problems solved by technology

[0002] With the improvement of the manufacturing level of large and super-large gears, the measurement level and detection accuracy of gears must be improved accordingly. The existing gear measuring instruments are difficult to meet the measurement level and detection accuracy of large and super-large gears. And super-large gears have large loads. On the one hand, large loads and load changes can easily cause deformation of the overall mechanism of the measuring instrument; second, it is difficult to ensure high precision and high sensitivity when the rotary table moves with a large load; third, large-quality workpieces The large inertia during rotation will have an impact on the control system parameters

Embodiment Construction

[0024] Attached below figure 1 , 2 , 3, 4 describe an embodiment of the present invention.

[0025] A large-scale gear measuring instrument, which is composed of mutually independent three-coordinate measuring device 36, rotary table 22 and tailstock column device 37, and the three-coordinate measuring device 36 and tailstock column device 37 are located on the rotary table 22 sides. The rotary table 22 is centered and assembled on the rotary table base 7 through the support of the hydrostatic guide rail and the hydrostatic bearing;

[0026] The bottom plate 101 of the rotary table 22 is horizontally fixed on the base 7 of the rotary table. The bottom plate 101 is equipped with a static pressure plate 104. The inner hole 116 and the upper and lower end surfaces of the static pressure plate 104 are provided with a static pressure oil chamber 117. The ring-shaped end surface of the lower end of the table top 108 is attached to the upper end surface of the static pressure plat...

Abstract

The invention provides a large gear measuring instrument. The gear measuring instrument comprises a measuring device and a rotary worktable mutually independent and arranged side by side, and the measuring device is located on one side of the rotary worktable; the rotary worktable is centered and assembled on a pedestal of the rotary worktable through a liquid hydrostatic slideway bearing and a liquid hydrostatic bearing; and the rotary worktable is driven by a twin-worm backlash eliminating transmission mechanism installed on the pedestal of the rotary worktable. The large gear measuring instrument comprises three mutually independent parts including the three-dimensional measuring device, the liquid hydrostatic rotary worktable and a tailstock pillar device, and the liquid hydrostatic rotary worktable can bear loads with large mass; the split type structure can reduce the influence of loads with small mass on measurement accuracy so as to meet the purpose of precision measurement on gears with large mass and large inertia.
