Description
Technical field
The utility model relates to erratic star wheel field, is specifically related to a kind of novel erratic star wheel.
Background technology
Sapphire is the important materials of processing blue light diode, has very important status at semiconductor applications.Before the sapphire sheet making client's needs, grind after will cutting into slices to sapphire.In prior art, the double side grinding process that adopts after sapphire slices is processed more.Add man-hour, by grounds travel particle, sapphire sheet is ground.The grinding of sapphire liner is a very important technological process during sapphire substrate manufactures, and which determines the total thickness variations of wafer after sapphire slices, angularity, the correlated qualities such as surface roughness.Time traditional carrier is used for the grinding to all kinds of non-standard, cause cost high, after grinding, defect is many, and easy fragmentation, so there is Combined wheel, but existing Combined wheel in use, and between Combined wheel, friction is large, heat dispersion is poor, and Combined wheel is fragile, improves production cost.
Utility model content
For solving the problem, the utility model provides a kind of novel erratic star wheel, when making work, creates certain buffer strip, improve yield rate between female wheel and son wheel.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of novel erratic star wheel, comprise female wheel and son wheel, female wheel excircle is provided with the tooth mated with milling apparatus, have some through holes of to take turns external diameter with described son and matching in it, through hole is provided with one group of wire casing I and group wire casing II, the bottom of described wire casing I and wire casing II is semicircle, top is rectangle, and top is provided with reducing; The width of described wire casing I is 3.7 ~ 3.9 millimeters, and the degree of depth is 1.7 ~ 1.9 millimeters; The width of described wire casing II is 3.7 ~ 3.9 millimeters, and the degree of depth is 1.4 ~ 1.6 millimeters, and described son wheel is provided with the projection matched with described wire casing I, wire casing II and reducing.
As preferably, described one group of wire casing I comprises eight wire casing I, and one group of wire casing II comprises 16 wire casing II.
As preferably, in described son wheel, be provided with the hole holding workpiece to be processed.
As preferably, the width of described wire casing I is 3.8 millimeters, and the degree of depth is 1.8 millimeters; The width of described wire casing II is 3.8 millimeters, and the degree of depth is 1.5 millimeters.
The utility model, by rationally arranging two groups of wire casing I and wire casing II varied in size, when making work, creates certain buffer strip between female wheel and son wheel, improves yield rate.
Accompanying drawing explanation
Fig. 1 is the female wheel structural representation of a kind of novel erratic star wheel of the utility model embodiment.
Fig. 2 is the structural representation of an embodiment of the utility model neutron wheel.
Fig. 3 is the structural representation of an embodiment of the utility model neutron wheel.
Detailed description of the invention
In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Figure 1-3, this concrete enforcement provides a kind of novel erratic star wheel, comprise female wheel 1 and son wheel 5, female wheel 1 excircle is provided with the tooth mated with milling apparatus, have some through holes 2 of to take turns 5 external diameters with described son and matching in it, through hole 2 is provided with one group of wire casing I 3 and one group of wire casing II 4, the bottom of described wire casing I 3 and wire casing II 4 is semicircle, top is rectangle, and top is provided with reducing; The width of described wire casing I 3 is 3.7 ~ 3.9 millimeters, and the degree of depth is 1.7 ~ 1.9 millimeters; The width of described wire casing II 4 is 3.7 ~ 3.9 millimeters, and the degree of depth is 1.4 ~ 1.6 millimeters, and described son wheel 5 is provided with the projection 6 matched with described wire casing I 3, wire casing II 4 and reducing.
Described one group of wire casing I 3 comprises eight wire casing I, 3, one group of wire casing II 4 and comprises 16 wire casing II 4.
The hole holding workpiece to be processed is provided with in described son wheel 5.
The width of described wire casing I 3 is 3.8 millimeters, and the degree of depth is 1.8 millimeters; The width of described wire casing II 4 is 3.8 millimeters, and the degree of depth is 1.5 millimeters.
Wherein, the quantity of described through hole 2 is 4, and the material of described female wheel 1 is blue steel, and the material of described son wheel 5 is plastic material.
This is specifically implemented by rationally arranging two groups of wire casing I and wire casing II varied in size, and when making work, creates certain buffer strip, improve yield rate between female wheel and son wheel.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
