Description

Structurally improved flat surface abrasive cloth wheel

The utility model relates to a kind of polishing disk that is used to polish, and particularly relates to a kind of structurally improved flat surface abrasive cloth wheel.

Please consult shown in Fig. 1,2 simultaneously, it mainly is made up of a some emery cloth A and a disk B to commonly use flat surface abrasive cloth wheel, wherein emery cloth A is to glue together the mode stationary arrangement on disk B, because emery cloth A only combines with disk B in the gummed mode, therefore when rotation polishing friction is used at a high speed, be easy to make it to come off and can't continue to use.With the use situation of present flat surface abrasive cloth, because of emery cloth A comes off the quantity of scrapping will be greater than the quantity of using abrasion naturally, it does not meet economic benefit except owing to frequent replacing emery cloth A brings inconvenience, more will cause the raising of use cost.In addition, please cooperate again and consult Fig. 3, because disk B is for bearing emery cloth A, so its diameter only be slightly less than glue and after emery cloth A outer rim, and the occupation mode of this flat surface abrasive cloth wheel mainly is to utilize the outward flange of emery cloth A, the suitable angle that tilts contacts polished thing, so the abrasion situation of this flat surface abrasive cloth wheel is the inwardly wearing and tearing gradually of outer rim by emery cloth A.Commonly using flat surface abrasive cloth wheel, when emery cloth A wears away to disk B top, promptly can't continue again for polishing operation, avoiding the polished thing of disk B scratch surface, and emery cloth A can't effectively be utilized, cause the waste of material.

Main purpose of the present utility model is to provide a kind of structurally improved flat surface abrasive cloth wheel, and it can firmly fix emery cloth, effectively utilizes emery cloth, avoids waste of material, and then improves the structurally improved flat surface abrasive cloth wheel of its fastness, durability.

The purpose of this utility model is realized by following technical scheme.

A kind of structurally improved flat surface abrasive cloth wheel, comprise polylith emery cloth sheet and disk, its improvements are: the medial extremity of each emery cloth sheet is set as a breach for one jiao in the described polylith emery cloth sheet, makes another dihedral become bare terminal end, the overlapping emery cloth wheel face that is arranged in a ring-type of this polylith emery cloth sheet; Described disk is the emery cloth dish, and the emery cloth that it adopted is for circular, and its central authorities are provided with a recessed groove, and recessed groove central authorities are provided with a circular hole; Also be provided with clamp ring and lower clamping, wherein go up clamp ring central authorities and be provided with a circular hole, its outer ring edge is auxilliary strong its stress and punching press is set as a Jiong shape lip limit; Lower clamping, its central authorities are provided with a circular hole, and upwards form a convex wall in its interior ring edge.

Whereby, last clamp ring and lower clamping can be placed on emery cloth wheel face inner edge, by stamping technology Zhe is turned in the outside punching press in the upper end of convex wall and form a lip limit, make its pressing on last clamp ring, and then clamping emery cloth sheet securely, bottom surface with emery cloth sheet, lower clamping is glued on the emery cloth dish again, so that it is combined into firm, a durable emery cloth wheel.

Concrete structure of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Fig. 1 is a schematic perspective view of commonly using the flat surface abrasive cloth wheel construction.

Fig. 2 is a vertical view of commonly using the flat surface abrasive cloth wheel construction.

Fig. 3 is a cutaway view of commonly using the flat surface abrasive cloth wheel construction.

Fig. 4 is the exploded perspective schematic diagram of the utility model structure.

Fig. 5 is the vertical view of the utility model structure.

Fig. 6 is the cutaway view of the utility model structure.

As shown in Figure 4, the utility model mainly is made up of parts such as clamp ring 20, lower clamping 30, emery cloth dish 40 on polylith emery cloth sheet 10 and, wherein:

Polylith emery cloth sheet 10, one jiao of the medial extremity of its each emery cloth sheet 10 make another dihedral become bare terminal end 11 through cutting into a breach, and this polylith emery cloth sheet 10 can form the emery cloth wheel face of a ring-type through overlapping arrangement.

Last clamp ring 20, it is to be made by the sheet metal punch forming, and its central authorities are provided with a circular hole 21, and its outer ring edge is auxilliary strong its stress and punching press is set as a Jiong shape lip limit.

Lower clamping 30, it is to be made by the sheet metal punch forming, is provided with a circular hole 31 in the central, and encircles edge within it and upwards form a convex wall 32.

Emery cloth dish 40, it is to cut into circle with emery cloth, and its central authorities are provided with a recessed groove 41, and recessed groove 41 central authorities are provided with a circular hole 42.

Please consult Fig. 5,6 simultaneously, the utility model is nested with the emery cloth wheel face inner edge that forms by some emery cloth sheet 10 overlapping arrangements by last clamp ring 20 with lower clamping 30, and at this moment, the convex wall 32 of lower clamping 30 can upwards be placed through in the circular hole 21 of clamp ring 20.By stamping technology the upper end of convex wall 32 is formed a lip limit 32A to the Zhe that turns up, pressing is on last clamp ring 20, and then can be by last clamp ring 20 and lower clamping 30 bare terminal end 11 of clamping emery cloth sheet 10 securely, card with emery cloth dish 40 is coated with sticker again, and exert pressure the bottom surface of emery cloth sheet 10, lower clamping 30 is glued on the emery cloth dish 40, so that it is combined into an emery cloth wheel securely.

From the above and embodiment shown in the drawings as can be known, the utility model mainly is held on the bare terminal end 11 of some emery cloth sheets 10 by last clamp ring 20 and lower clamping 30, make its combination more securely, cooperate sticker again and be glued on the emery cloth dish 40, when reaching rotation polishing at a high speed, emery cloth sheet 10 can not produce the shortcoming that comes off.When the outward flange of emery cloth sheet 10 tilts an angle when polishing action, its abrasion situation is by the inwardly wearing and tearing gradually of outer rim of emery cloth sheet 10, when emery cloth sheet 10 wears away to emery cloth dish 40 (the disk B that is equivalent to commonly use) top, this emery cloth dish 40 is also with the 10 friction polishings of emery cloth sheet, except can effectively utilizing emery cloth sheet 10, it can not caused outside the waste of material, and this emery cloth dish 40 more help to rub carrying out of polishing improved its practicality greatly and saves material cost.

Therefore, the utility model has the progressive that improves the practical usefulness of product really, and its structure be not seen on the market, so meet the important document of novel patent application.
