Abstract

The utility model discloses a grinding device for buttons made of hard stone materials, such as gemstones and jadestones. At least one group of loading mould disks and grinding disks are arranged in the structure, the grinding disks can contact with the loading mould disks, and the grinding disks can also be used for grinding. Button materials can be positioned and fixed on the grinding surface of the loading mould disk, the grinding surface shape of the grinding disk corresponds to the grinding surface of the loading mould disk, and the grinding surface of the grinding disk is coated with grinding materials. At least one of the loading disk and the grinding disk can be driven by a driving mechanism to rotate; when one of the loading disk and the grinding disk is connected with an appropriate swing mechanism, the disk can also simultaneously make reciprocating swinging slip motion during the rotating and grinding time, which is even better for balancing grinding and preventing partial rapid abrasion of the grinding device.

Description

Abrasive device for hard stone material button

The utility model relates to a kind of lapping device of processing rigid building stones class button, be specially adapted to process gem and jade class button.

The button of using on the business suit mostly is macromolecular material compression mouldings such as plastics, lucite.As hard stone buttons such as rock quartz, agate, gem and jade then still can only be by the grain attrition process by artificial, not only labour intensity is big, and efficient is low, and the quality of button, specification can't guarantee unified standard, also greatly limit output, be difficult to satisfy the demand that garment processing industry increases day by day.

The purpose of this utility model is to provide a kind of attrition process hard stone button that can be used for for addressing this problem, the lapping device of the high-grade button of particularly various gem and jade classes.

At least be provided with the grinding mill that one group of loading mould grinds with being in contact with it in the button lapping device of the present utility model.The lapped face of loading mould can be multi-form for plane, convex surface or concave surface etc., but from make things convenient for production operation with convex form for well.Can be provided with on this lapped face as the placement of appropriate formats such as groove, draw-in groove and fixedly fixing, the location structure of button blank, even also can directly it be bonded on this abradant surface.Grind mill with the contacted abradant surface of loading mould lapped face on be coated with grinding abrasives such as diamond dust, carborundum powder, and its shape also should adapt with the shape of loading mould lapped face.Under driving mechanism drives, the loading mould and grind in the mill rotation another static or the two do rightabout rotation simultaneously, all can between its contacted abradant surface, produce to grind and move, the button blank that is opposite on the loading mould grinds.

In the grinding campaign of this rotation, be in the button at loading mould centre and peripheral position owing to have different abrasive wire speed, the degree of wear of its degree of grinding and grinding mill all is unbalanced., loading mould and the side and the suitable swing mechanism that grind in the mill can be linked, this swing mechanism should make this, and the two can produce the sliding motion of reciprocally swinging formula for this reason.The area that grinds the mill abradant surface this moment preferably can be less than the area of loading mould lapped face.The result of the sliding motion of this reciprocally swinging formula just can make the button at the higher peripheral position of abrasive wire speed on the loading mould be ground by batch (-type) ground, the button that is in the lower centre of linear velocity is then by continuously grinding, and the degree of wear of grinding mill also can be tending towards balanced.Though with the loading mould with grind mill and be connected in respectively simultaneously and also can make it produce relative sliding motion on the swing mechanism that can do the rightabout motion, obviously can make structure complicated, also not have this kind necessity.Comparatively simple mode then is to have only in the two at this under the situation of side with the driving mechanism rotation, and a non-rotary side and swing mechanism are linked.

Below specify structure of the present utility model by example shown in the drawings, but obvious scope of the present utility model is not limited in following example.

Fig. 1 structural representation of the present utility model

The plan structure state of Fig. 2 Fig. 1

As seen from the figure, being connected with the loading mould 4 that a lapped face evagination is dome shape, be fixed with some button blanks 5 with bonding mode on its lapped face in the button lapping device of the present utility model by the top of the front axle 3 of motor 1 driven rotary.The top of loading mould 4 is provided with an abradant surface can grinding mill 6 contacted with it, the indent dome shape of its abradant surface for adapting with loading mould 4 lapped face shapes, its area is less than the area of loading mould 4 lapped faces, and is coated with grinding abrasive.Grinding mill 6 links by universal hinging mode and the spherical inserted link 11 that is connected on the swing mechanism 10.One end of swing mechanism 10 for the swing rotating shaft 13, other end support on supporting plate 14, and by connecting rod 9 be connected in rear axle 7 joining eccentric wheels 8 on.Motor 1 rotates at the loading mould 4 that drives front axle 3 and be connected on the front axle, and when compressing thereon 6 on grinding mill and produce the spin finishing motion by self gravitation, belt pulley on the front axle 3 has also driven rear axle 7 and connection eccentric wheel 8 rotations thereon simultaneously, connecting rod 9 promptly drives

swing mechanism

10 and 13 makes reciprocally swinging around the shaft, by with it joining spherical inserted link 11 just can make grind mill 6 and loading mould 4 when doing the spin finishing motion again at the sliding motion of making the reciprocally swinging formula.

If be provided with the above-mentioned loading mould of many groups in this example simultaneously and grind disc-grinding mechanism, then grinding efficiency can improve greatly.

Claims
