[specific embodiment]

Below the structure of main accompanying drawings numerical control rotary table.This numerical control rotary table is mainly used in laser cutting machine incising pipes usefulness, and central through-hole footpath is big, cooperates different laser cutting machine chucks can realize cutting processing to tubing such as pipe, square tube, conical tube, elliptical tubes.

As Fig. 1-shown in Figure 4, numerical control rotary table comprises pedestal 10 and is fixed on motor 20 and transmission device on the pedestal 10.Transmission device comprises pinion 30 and revolution support wheel 40.Motor 20 is fixed on a side of pedestal 10, and pinion 30 and revolution support wheel 40 are fixed on the opposite side of pedestal 10.

Pinion 30 is driven by motor 20, rotatablely moves by driving revolution support wheel 40 with 40 external toothings of revolution support wheel.Revolution support wheel 40 high-precision gear structures for customization, rotary part 42 and support component 44 are combined, simplified frame for movement greatly, revolution support wheel 40 central authorities are provided with through hole, the aperture is 210mm, can satisfy the process requirements of different-diameter tubing.

In preferred embodiment, pinion 30 adds resilient tensioning anti-backlash mechanism for a pair of bidentate wheel that is linked in together between two pinions, pinion 30 and gear wheel 40 are meshed fully, eliminates backlass, improves running accuracy.The tensioning anti-backlash mechanism is one group of compression spring and backing pin combination, opposite face at two pinions 30 has relative arc groove, in arc groove, place compression spring and backing pin, under the effect of compression spring power, two pinions 30 are done relative twist motion, and the transverse tooth thickness that is equivalent to pinion 30 strengthens, and pinion 30 and gear wheel 40 are meshed fully, eliminate backlass, improve running accuracy.

In preferred embodiment, motor 20 adopts servomotor, and also the be provided with reductor 50 of numerical control rotary table between motor 20 and pinion 30 carries out the one-level deceleration, preferably high-precision planetary reducer, speed reducing ratio between itself and the pinion 30 is 8: 1, cooperate the double reduction (speed reducing ratio is 19: 4) between pinion 30 and the revolution support wheel 40, the speed reducing ratio of whole numerical control rotary table is 38: 1, be much higher than the rotary table 180: 1 of general import equipment or 90: 1 speed reducing ratio, the raising of several times the rated speed of revolution support wheel 40, be fit to the laser cutting machine cutting at a high speed, processing characteristic efficiently.In addition, on pedestal 10, also be provided with zero-bit switch 60, be used for the servomotor processing of making zero that when workbench starts, resets.
