Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is A-A direction of the present invention schematic cross-section.
Wherein: 1-motor, 2-shaft coupling, 3-servomotor I, 4-upright guide rail, the upper planker of 5-, 6-horizontal guide rail, 7-diamond wheel, planker under 8-, 9-servomotor II, 10-pulley mechanism, 11-ball screw framework.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described further:
As Fig. 1 and Fig. 2, a novel numerical control crushing for screw rotor grinding machine, comprises motor 1, two shaft couplings 2, a servomotor I 3, a upright guide rail 4, upper planker 5, horizontal guide rail 6, two diamond wheels 7, a lower planker 8, servomotor II 9, pulley mechanism 10 and two ball screw frameworks 11.
