Description

Erratic star wheel

Technical field

The utility model relates to a kind of erratic star wheel.

Background technology

Erratic star wheel is applied in glass, eyeglass, silicon chip, and the fixture of the various plane polishing operation such as hard disk, be otherwise known as polishing jig or polishing pad etc.Current erratic star wheel is generally made up of glass-fiber-plate or is made up of metallic steel, but in concrete use procedure, the erratic star wheel wearability that glass-fiber-plate is made is inadequate, intensity is little, and can exert pressure to erratic star wheel during machine operation, service life is short then, quality is unstable, and cost own is also high; In the erratic star wheel course of work that metallic steel is made, the easy striking work in its edge, causes product fraction defective to promote, and rapid wear machine.

Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of erratic star wheel of new structure, make it have more value in industry.

Utility model content

The purpose of this utility model is to provide a kind of erratic star wheel, and it can reduce coefficient of friction, reduces product fraction defective, improves service life and reduce costs, and this erratic star wheel is when ensureing compression resistance, and thickness can be thinner.

In order to achieve the above object, the utility model adopts following technical scheme: a kind of erratic star wheel, comprise the matrix with inner ring hole and the core portion on the matrix and made by resin material is installed, described core portion is positioned at the inner ring hole of matrix, described matrix comprises metallic wheel body and is coated in the wear-resisting withstand voltage coating on described metallic wheel body, on the thickness direction of described erratic star wheel, the two sides in described core portion are protruded in the two sides of described matrix.

Further, the perimeter wall in described core portion is provided with the chimeric block of some T-shaped shapes, on the inner wall of the inner ring hole of described matrix, depression is formed with the embedded hole of T-shaped shape, and described chimeric block is embedded in described embedded hole.

Further, laser weld is passed through between described chimeric block and embedded hole.

Further, bondd by adhesive between described core portion and the inner ring hole of matrix.

Further, described core portion buckle is fixing on the matrix.

Further, described resin material is the one in high strength epoxy resin, amide based resins, acrylic resin, mylar.

Further, described wear-resisting withstand voltage coating is diamond-like coating or titanium nitride coating.

By such scheme, the utility model at least has the following advantages: because erratic star wheel of the present utility model is combined by matrix and core portion, matrix is the metallic wheel body being coated with wear-resisting withstand voltage coating, and again on the thickness direction of erratic star wheel, the two sides in core portion are protruded in the two sides of matrix, thus operationally, buffering stress can be provided, reduce product fraction defective, reduce coefficient of friction, improve the core in service life of erratic star wheel, reduce cost; In addition, compared with prior art, when identical compression resistance, the thickness of erratic star wheel of the present utility model can be thinner.

Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model erratic star wheel;

Fig. 2 is the enlarged drawing of circle A in Fig. 1.

Detailed description of the invention

Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.

See Fig. 1 and Fig. 2, a kind of erratic star wheel 10 described in the utility model one preferred embodiment comprises the core portion 2 having matrix 1 and be arranged on described matrix 1, inner ring hole 11 is formed in described matrix 1, the outer circumference of matrix 1 is formed with the gear teeth 12, described core portion 2 is positioned at the inner ring hole 11 of matrix 1, and described matrix 1 comprises metallic wheel body (not shown) and is coated in the wear-resisting withstand voltage coating (not shown) on described metallic wheel body.On the thickness direction of described erratic star wheel 10, the two sides in described core portion 2 are protruded in the two sides of described matrix 1, and namely the thickness of matrix 1 is greater than the thickness in core portion 2.This core portion 2 is made by resin material, in the present embodiment, described resin material is high strength epoxy resin, wear-resisting withstand voltage coating is diamond-like coating, certainly, in other embodiments, described resin material can also be the one in amide based resins, acrylic resin, mylar, and wear-resisting withstand voltage coating can be titanium nitride coating.

In the present embodiment, the perimeter wall in described core portion 2 is provided with the chimeric block 21 of some T-shaped shapes, on the inner wall of the inner ring hole 11 of described matrix 1, depression is formed with the embedded hole 13 of T-shaped shape, and described chimeric block 21 is embedded in described embedded hole 13, and passes through laser weld between the two.By this kind of structure, core portion 2 can be made to be connected with matrix 1 tightr, when avoiding work, workpiece the accident such as frequently to clash into and easily comes off.Certainly, in other embodiments, described core portion 2 and matrix 1 can also combine by other means, e.g., are bondd between described core portion 2 and the inner ring hole 11 of matrix 1 by adhesive; Or described core portion 2 is fixed on described matrix 1 by buckle structure.

In sum, above-mentioned erratic star wheel 10 tool has the following advantages:

1, because erratic star wheel 10 is combined by matrix 1 and the core portion 2 made by resin material, matrix 1 for being coated with the metallic wheel body of wear-resisting withstand voltage coating, so relative to existing technologies, it can reduce costs;

2, because inside is the core portion 2 made by resin material, so, when work, the shock of stress can be cushioned, contribute to the fraction defective reducing product, and the service life of this erratic star wheel 10 can also be improved;

3, due on the thickness direction of erratic star wheel 10, the two sides in core portion 2 are protruded in the two sides of matrix 1, so when avoiding work, workpiece is to the friction in core portion 2 and exert pressure, contribute to the service life of improving erratic star wheel 10;

4, because matrix 1 is for being coated with the metallic wheel body of wear-resisting withstand voltage coating, so, add the wearability of erratic star wheel 10, add compression resistance advantage, and the corruption rust of all right isolating metal wheel body itself, thus improve the corrosion-resistant of this erratic star wheel, make grinding, coefficient of friction when reducing polishing and between two-way pressure dish; In addition, when identical compression resistance, the thickness of this erratic star wheel 10 can be thinner;

5, by the cooperation of the chimeric block 21 in core portion 2 and the embedded hole 13 of matrix 1, core portion 2 can be made to be connected with matrix 1 tightr, when avoiding work, workpiece the accident such as frequently to clash into and easily comes off.

The above is only preferred embodiment of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
