Description

The cloth wheel

Technical field

The utility model relates to a kind of instrument that polishes usefulness, relate in particular to a kind of cloth wheel that can carry out meticulous polishing to the surface of workpiece, it is mainly used in carries out polishing to the surface of workmanship (as carving), five metals device, mechanical workpieces and building.

Background technology

When polishing was carried out on the surface of workpieces such as carving, five metals device, mechanical workpieces and building, method commonly used was that the cloth wheel is inserted in the chuck of electronic or pneumatic tool (as electric drill), carried out under the latter's high speed rotation drives.

Visible Fig. 1 of structure of the cloth wheel of common in the market polishing usefulness, its primary structure characteristics are: the body 1 ' of cloth wheel is made up of multilayer wool cloth 3 ', is bonded together with seccotine between each layer wool cloth 3 ', in order to avoid break away from mutually; Also have a round bar 2 ' behind its surface coating seccotine, to insert in addition from the bottom of cloth wheel body 1 ', the shape of the other end of this round bar 2 ' and specification then are complementary with the chuck of electronic or pneumatic tool (as electric drill), so that round bar can be installed to smoothly and carries out work in the above-mentioned chuck when using.

Yet there is following shortcoming in above-mentioned cloth wheel: the cloth wheel that (1) has said structure can only utilize its side as the polishing face, and its top end face can not be used for workpiece is carried out polishing; And the cloth wheel generally is mounted in this type electric tool of electric drill or other pneumatic tools, the high speed of relying on the latter is rotated the motion that drives self, so when handling big flat work pieces, when particularly polishing being carried out in the middle part on big plane, the side of cloth wheel has only the part to contact with machined surface, contact-making surface is little, and inhomogeneous, insufficient, operating difficulties, inefficiency; (2) in addition, concave surface, the particularly dark concave surface that uses such cloth wheel also to be difficult to workpiece carries out the effective polishing processing; (3) between each layer cloth owing to be to bond together with seccotine, this operation is obviously comparatively numerous and diverse, uses between each layer cloth of back to break away from mutually easily, scraps very soon thereby cause this cloth to be taken turns; (4) moreover, because the above-mentioned round bar that is installed in the chuck of instrument such as electric drill is also fixing with cloth wheel body by seccotine, so same disengaging mutually easily between them, insecure, be not durable.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of its top end face and also can be used as the polishing face and make the cloth wheel easier, that applicability is wider, more durable.

The technical scheme in the invention for solving the technical problem is: the body of this cloth wheel is made up of laminates, and comprise and be with externally threaded connector, ring, pad and tapped bar, describedly be with externally threaded connector to run through every layer of cloth, ring and pad successively, this is with the end and the tapped bar thread connection of externally threaded connector, and described cloth embeds in the ring.

Tapped bar described in the utility model can be tapped hexagonal bar.

Cloth described in the utility model is cotton.

The utility model compared with prior art, its advantage is: (1) since the laminates of the utility model cloth wheel be embedded in the ring, can make each layer cloth upwards closely bundle close, thereby be able to form the polishing face at the top end face of cloth wheel; The formation of this top polishing face has not only increased work area than the cloth wheel of prior art, and can mould the polishing face that shape adapts with it arbitrarily according to the difference of work piece; (2) because the polishing face of this cloth wheel is omnibearing, overcome the defective of the instruments such as electric drill that match with it thus, make it to be advantageously used in to the middle part of big flat work pieces and the polishing of dark concave surface, thereby enlarged the scope of application that this cloth is taken turns; (3) owing to be with externally threaded connector to run through all layer of cloths, its end has tapped bar fastening again, so each layer cloth combines closely mutually reliably, does not need to bond together with seccotine again, saves the production process of cloth wheel thus, and this cloth wheel is also more durable; (4), more easy to operate during therefore acquisition easily, and hexagonal bar mounting or dismounting than circular pin because tapped hexagonal bar is a general part; (5) because the cloth of cloth wheel body is a cotton, therefore than low, the easier acquisition of cloth of cost of wool.
