The beneficial effects of the utility model are:
Than prior art, the utility model is at a plastics sliding sleeve of the outside socket of axle despot, the through-hole wall of this plastics sliding sleeve and axle core is slidably matched, thereby in the time that axle despot moves back and forth, alleviate the wearing and tearing to axle core, increase the service life of axle core, and guaranteed that electric main shaft has higher running precision; In addition, the utility model also has advantages of simple in structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 10, axle core; 11, through hole; 12, taper portion; 13, end ring; 14, copper mouse cage; 15, flux sleeve; 16, flywheel; 17, flange; 20, axle despot; 21, plastics sliding sleeve; 30, chuck; 40, dish spring; 50, cutter.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
As shown in Figure 1, for a kind of air floated high speed electric mandrel axle core component of the present utility model, it comprises axle core 10, axle despot 20, chuck 30 and dish spring 40, wherein, axle core 10 inside are provided with a through hole 11, this through hole 11 is through to the lower surface of axle core 10 by the upper surface of axle core 10, the bottom of through hole 11 is provided with a taper portion 12, and the internal diameter of this taper portion 12 from top to bottom increases successively.Axle despot 20 is arranged in through hole 11, and it can be along the sliding axially of through hole 11, and concrete, axle despot 20 outer surface fixed cover is connected to a plastics sliding sleeve 21, and this plastics sliding sleeve 21 is slidably matched with through hole 11 inner surfaces of axle core 10.Chuck 30 is arranged on the bottom of through hole 11, and the upper end of this chuck 30 is fixedly connected on axle despot 20 bottom, and chuck 30 coordinates with taper portion 12, for clamping cutter 50.Dish spring 40 is arranged between axle despot 20 and axle core 10, it is for applying an elastic stress upwards to axle despot 20, make the upwards direction of taper portion 12 (away from) motion of axle despot 20, the top ends that is positioned at taper portion 12 at through hole 11 inwalls of axle core 10 is provided with a flange 17 being positioned at below axle despot 20, dish spring 40 is enclosed within the outside of chuck 30, and the lower surface that is pressed on flange 17 and axle despot 20 is pushed up respectively at its two ends.
