Description
Technical field
The utility model belongs to optical mirror slip manufacture field more particularly to a kind of erratic star wheel for optical mirror slip.
Background technology
The consumptive material that erratic star wheel is used as grinder is widely used in piezo-electric crystal, optical glass producing, sapphire and adds
The industries such as work, Ceramic manufacturing are indispensable production consumptive materials in modern industrial production activity.In recent years, with science and technology
Fast development, finished product base material crystal wafer demand increasingly increases, and especially the popular electronics product such as mobile phone, tablet computer is general
And touch screen rapid development, more so that eyeglass precise finiss polishing demand is at a tremendous pace, therefore, to the processed goods of finished product base material
More stringent requirements are proposed for matter and yield rate, also has higher expectation to erratic star wheel.But existing erratic star wheel is unfavorable for throwing
The generation of the problems such as circulation of light powder liquid, the easy scattered error degree or even sliver for increasing piece.
Invention content
To solve the above-mentioned problems, the utility model provides a kind of erratic star wheel for optical mirror slip, can improve powder liquid
Fluency, reduce piece scattered error and throw piece when resistance.
It adopts the following technical scheme that thus：A kind of erratic star wheel for optical mirror slip, including erratic star wheel ontology, the trip
Several gears are arranged in star-wheel body peripheral, and several cavities and stream powder hole are opened up on the erratic star wheel ontology, it is characterised in that：It is described
Cavity includes the unit cavity of rectangle or square, and the unit cavity is in inside and outside two ring centered on the erratic star wheel center of circle
Shape is distributed, and the inner ring, which is equipped with outer ring between unit cavity and each unit cavity, has equal central angle；The stream
Including one to three-level unit stream powder hole, wherein first order unit stream powder hole is located at the erratic star wheel center of circle, first order unit stream powder in powder hole
Hole is circular hole and the center of circle is overlapped with the erratic star wheel center of circle, and second level unit stream powder hole is described between each inner ring each unit cavity
Second level unit stream powder hole is in irregular polygon hole；Third level unit stream powder hole is located between each unit cavity of outer ring, described
Third level unit stream powder hole hole triangular in shape.
Further, in the unit cavity of the inside and outside two circles distribution of the erratic star wheel, outer ring is equipped with 8 square units
Cavity has 45 ° of central angles in outer ring between two neighboring haplotype lumen type chamber；The inner ring is equipped with 3 square units
Cavity has 120 ° of central angles in inner ring between two neighboring unit cavity.
Further, the first order unit stream powder hole is the circular hole of diameter 20mm；The second level unit stream powder hole packet
Include two irregular quadrilateral holes and an irregular pentagon hole, the second level unit stream powder hole and inner ring unit cavity
Outline border spacing is 7-9mm；The third level unit stream powder hole includes 8 tri-angle-holed, and third level unit stream powder hole and outer ring are single
The outline border spacing of first cavity is 6-8mm.
Further, four interior angles of the unit cavity are respectively equipped with circular chamfer groove, the chamfer groove
Radius is 1-1.1mm.
It, can be effectively in circular motion by upper disk stream by the stream powder hole being arranged to the full extent on erratic star wheel and cavity
Under polishing fluid be more assigned to lower wall polishing pad so that the chemical reaction in polishing process reaches relatively flat with mechanism
Weighing apparatus greatly reduces the generation of machinery scuffing, improves the yields of polishing product.Through the above scheme, it is arranged on erratic star wheel
Inside and outside two ring chamber and three-level stream powder hole, not only increase cavity, increase the number of erratic star wheel while converted products, improve
Processing efficiency, and the stream powder number of perforations of erratic star wheel is increased to the full extent, improve the fluency of powder liquid, reduces dissipating for piece
Resistance when difference and throwing piece.Through the above scheme, hence it is evident that improve the uniformly penetrating of polishing powder, reduce and throw the frightened situations such as split of piece
Occur.
