Description
Technical field:
The utility model relates to the improvement of the processing unit (plant) of eccentric bushing.
Background technology:
Eccentric bushing is one of critical piece of gyratory crusher.The processing arrangement of eccentric bushing carried out on 3 meters sleeping carriages or 5 meters sleeping carriages in the past, used the processing of rimmer knife bar usually.But because eccentric bushing is oversize, the length that causes processing knife bar is long, makes the rigidity deficiency of knife bar; Knife bar produces the cutter relieving phenomenon man-hour adding, and it is low that tapered sleeve rough surface after the processing is spent, and influenced the precision and the quality of product, even produces and scrap.
The utility model content:
The utility model is exactly at the problems referred to above, a kind of production efficiency height is provided, can guarantees the processing unit (plant) of the eccentric bushing of product quality.
For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises base, and the two ends, the left and right sides on the base are respectively arranged with unit head, revolving body, between the chuck of its structural feature unit head and the revolving body leading screw is set, the screw of leading screw is provided with cutter; The barreled tooth flank of leading screw termination is meshed with the internal gear of inner rotary member in the revolving body, and the lateral denticle wheel that is fixedly coupled dish on the connecting axle is meshed with the internal gear of external rotary member, the internal gear of inner rotary member, and the internal gear of external rotary member is fixed on the connecting axle; The gland of revolving body is provided with holding screw; The external rotary member internal gear is provided with clutch on the connecting axle, and a side of clutch is provided with dog screw; The internal gear of inner rotary member lacks a tooth than the internal gear of external rotary member, but the modulus of gear is identical.
The beneficial effects of the utility model:
The utility model has been realized the high-quality and high-efficiency of eccentric bushing processing by differential feed mechanism of moving forward, increases work efficiency 20%, and the roughness of eccentric bushing concentric reducer endoporus has been reached more than the Ra0.8, has guaranteed quality.The utility model amount of feeding is less, stable, compact to design, more be applicable to the empty eccentric bushing fine finishining in the various gyratory crushers.

The specific embodiment:
The utility model comprises base 1, and the two ends, the left and right sides on the base 1 are provided with unit head 2, revolving body 6 respectively, between the chuck 3 of unit head 2 and the revolving body 6 leading screw 4 is set, and the screw 19 of leading screw 4 is provided with cutter head 22; The rack barrel 9 of leading screw 4 terminations is meshed with the internal gear 10 of inner rotary member 11 in the revolving body 6, the internal gear 10 that is fixedly coupled a dish lateral denticle of 14 wheel 13 internal gears 12 with external rotary member 16, inner rotary member 11 on the connecting axle 8 is meshed, and the internal gear 12 of external rotary member 16 is fixed on the connecting axle 8; The gland 15 of revolving body 6 is provided with holding screw 17; On the connecting axle 8 external rotary member 16 internal gears 12 be provided with clutch 7, a side of clutch 7 is provided with dog screw 18; The internal gear 10 of inner rotary member 11 lacks a tooth than the internal gear 12 of external rotary member 16, but the modulus of gear is identical.
Be fixed with knife rest 21 on the screw 19 on the leading screw 4, the both sides of knife rest 21 are provided with the cutter groove 20 of cutter 22, and the side of cutter groove 20 is provided with trip bolt 23.Screw 19 can be fixed in knife rest 21 on the screw 19 by pressing plate 24.
Below in conjunction with a description of drawings course of action of the present utility model:
In process, by the locking of clutch 7, revolving body 6 rotates under unit head 2 chucks 3 drive; When holding screw 17 unclamps, leading screw 4 revolution, but not feed.When holding screw 17 tightenings, the internal gear 12 of external rotary member 16 drives pinion 13 and rotates, and the internal gear 10 of 13 whiles of pinion and external rotary member 16 internal gears 12, inner rotary member 11 meshes simultaneously; The internal gear 10 of inner rotary member 11 meshes simultaneously with pinion 13, rack barrel 9 simultaneously; Differ under the situation of a tooth at the internal gear 12 of external rotary member 16 internal gear 10 with inner rotary member 11, leading screw 4 makes knife rest 21 segment distance of having gone ahead when rotating, and has just finished processing to eccentric bushing 5 through this process.
