Abstract
The utility model discloses a kind of easy-to-mount whirligig, comprise rotary body and the holder with described rotary body pivot joint, the bottom surface of described rotary body is upwards arranged with groove, the bottom surface of described groove is convexly equipped with rotating shaft downwards, the bottom surface of described rotating shaft exposes to the bottom surface of described rotary body, and the bottom surface of described rotating shaft is upwards arranged with pyramidal pits, described pyramidal pits matches with the tapered protrusion of projection upper surface in the middle part of described holder.The setting of pyramidal pits and tapered protrusion, makes rotary body can rotate flexibly around the tapered protrusion on holder, and meanwhile, make rotary body can dismounting easily, the utility model structure be simple, and flexible rotation, cost are low and be convenient to dismounting.
Description
Technical field
The utility model relates to machine tool accessory technical field, particularly relates to a kind of easy-to-mount whirligig.
Background technology
Whirligig under prior art in machine tool accessory, most complex structure, accessory is many, install loaded down with trivial details, cost is higher and be not easy to dismounting.
Utility model content
It is simple that the purpose of this utility model there are provided a kind of structure, the low and easy-to-mount whirligig of flexible rotation, cost.
For reaching this object, the utility model by the following technical solutions:
A kind of easy-to-mount whirligig, comprise rotary body and the holder with described rotary body pivot joint, the bottom surface of described rotary body is upwards arranged with groove, the bottom surface of described groove is convexly equipped with rotating shaft downwards, the bottom surface of described rotating shaft exposes to the bottom surface of described rotary body, and the bottom surface of described rotating shaft is upwards arranged with pyramidal pits, described pyramidal pits matches with the tapered protrusion of projection upper surface in the middle part of described holder.
Wherein, described groove internal clearance is combined with locating piece, and the middle part of described locating piece is provided with the axis hole with described rotating shaft matched in clearance, and the upper surface of the bottom surface of described locating piece and described holder fits tightly.
Wherein, gap is provided with between the upper surface of described holder and the lower surface of described rotary body.
Wherein, gap is provided with between the upper surface of described locating piece and described groove.
Wherein, the upper surface of described rotary body is provided with the screwed hole for fastening load.
Wherein, the outer surface of described tapered protrusion and described pyramidal pits is respectively arranged with wearing layer.
The beneficial effects of the utility model: the utility model comprises rotary body and the holder with described rotary body pivot joint, the bottom surface of described rotary body is upwards arranged with groove, the bottom surface of described groove is convexly equipped with rotating shaft downwards, the bottom surface of described rotating shaft exposes to the bottom surface of described rotary body, and the bottom surface of described rotating shaft is upwards arranged with pyramidal pits, described pyramidal pits matches with the tapered protrusion of projection upper surface in the middle part of described holder.The setting of pyramidal pits and tapered protrusion, makes rotary body can rotate flexibly around the tapered protrusion on holder, and meanwhile, make rotary body can dismounting easily, the utility model structure be simple, and flexible rotation, cost are low and be convenient to dismounting.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of easy-to-mount whirligig of the utility model.
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
In figure: 1. rotary body, 11. grooves, 12. rotating shafts, 13. pyramidal pits, 2. holder, 3. locating piece.
Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing 1 to Fig. 2
A kind of easy-to-mount whirligig, comprise rotary body 1 and the holder 2 with the pivot joint of described rotary body 1, the bottom surface of described rotary body 1 is upwards arranged with groove 11, the bottom surface of described groove 11 is convexly equipped with rotating shaft 12 downwards, the bottom surface of described rotating shaft 12 exposes to the bottom surface of described rotary body 1, and the bottom surface of described rotating shaft 12 is upwards arranged with pyramidal pits 13, described pyramidal pits 13 matches with the tapered protrusion of projection upper surface in the middle part of described holder 2.
As preferred embodiment of the present utility model, described groove 11 internal clearance is combined with locating piece 3, the middle part of described locating piece 3 is provided with the axis hole with described rotating shaft 12 matched in clearance, and the upper surface of the bottom surface of described locating piece 3 and described holder 2 fits tightly.The setting of locating piece 3, can play good correcting effect, when the load deviation of gravity center rotating shaft of rotary body upper surface, can play a very good protection to rotating shaft.
As further preferred embodiment, between the upper surface of described holder 2 and the lower surface of described rotary body 1, be provided with gap, between the upper surface of described locating piece 3 and described groove 11, be provided with gap.This structural design, is convenient to rotary body and better rotates.In order to further reduce the rotating friction force of rotary body, the outer surface of described tapered protrusion and described pyramidal pits 13 is respectively arranged with wearing layer, wearing layer preferably ceramic layer.
As further preferably, the upper surface of described rotary body 1 is provided with the screwed hole for fastening load.
Below know-why of the present utility model is described in conjunction with specific embodiments.These describe just in order to explain principle of the present utility model, and can not be interpreted as the restriction to the utility model protection domain by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, and these modes all will fall within protection domain of the present utility model.
