Abstract

A grinding wheel comprises a circular disk and an aluminum core component. A through hole is arranged at the center of the circular disk; the aluminum core component includes an integrated aluminum core cover, a nut and a locking part; the nut is positioned on the top of the aluminum core cover; the aluminum core cover is positioned on the top of the circular disk; a connecting threaded hole is arranged on the upper portion of an inner cavity of the nut; a positioning hole with a size same with that of a central hole of the aluminum core cover is arranged on the lower portion of the inner cavity of the nut and communicated with the central hole; the diameter of the positioning hole is larger than the large diameter of the connecting threaded hole; the locking part is composed of an integrated base plate and locking sleeves connected onto the top of the base plate; the locking sleeves are positioned inside the positioning hole and the through hole; the base plate is positioned at the bottom of the circular disk; a locking threaded hole is arranged on the upper portion of an inner cavity of the locking sleeve; the large diameter of the locking threaded hole is equal to that of the connecting threaded hole; and a hexagonal through hole capable of leading a wrench to be inserted into is arranged at the center of the base plate. The grinding wheel has the advantage of capability of repeatedly using the aluminum core component, thereby being capable of greatly saving use cost.

Description

Emery wheel

Technical field:

The utility model relates to a kind of grinding tool that is used for the metalwork surface is carried out grinding, specifically is a kind of reusable aluminium core assembly, thereby saves the emery wheel of use cost greatly.

Background technology:

At present, emery wheel on the market all is made up of an aluminium core assembly and the uniform circular disk body of thickness usually, the center of circular disk body has through hole, the aluminium core assembly is included as holistic aluminium core cap, be positioned at the nut at aluminium core cap top and be positioned at the aluminium core retainer plate that aluminium core cap bottom can be inserted into the circular disk body through hole, the screwed hole of nut communicates with aluminium core retainer plate round cavity, the aluminium core cap is positioned at the circular disk body top, when the aluminium core assembly of said structure is connected with circular disk body, the producer is inserted into the aluminium core retainer plate in the through hole earlier, and then aluminium core retainer plate and circular disk body through hole riveted, in other words, what aluminium core assembly and circular disk body adopted is non-dismountable connected mode, this makes that behind the abrasion of grinding wheel, the user has to aluminium core assembly and circular disk body are abandoned together, thereby causes bigger waste to the user.

The utility model content:

The technical problems to be solved in the utility model is a kind of reusable aluminium core assembly to be provided, thereby to save the emery wheel of use cost greatly.

Technical solution of the present utility model is, a kind of emery wheel with following structure is provided: it comprises circular disk body and aluminium core assembly, the circular disk body center has through hole, the nut that the aluminium core assembly is included as holistic aluminium core cap and is positioned at aluminium core cap top, the aluminium core cap is positioned at the circular disk body top, wherein, the aluminium core assembly also comprises a locking member, the inner chamber top of nut is the connecting thread hole, the inner chamber bottom of nut be one with identical size of aluminium core cap centre bore and the locating hole that communicates, the diameter of locating hole is greater than the big footpath in connecting thread hole, locking member is by forming for holistic chassis and the lock sleeve that is connected the top, chassis, lock sleeve is positioned at locating hole and through hole, the chassis is positioned at the circular disk body bottom, the inner chamber top of lock sleeve is the locking screw pit, and the big footpath of locking screw pit equals the big footpath in connecting thread hole, and center chassis has one can be for the hexagon through hole of spanner insertion.

After adopting above structure, compared with prior art, the utility model emery wheel has the following advantages: being riveted together by aluminium core retainer plate and circular disk body through hole with the prior art emery wheel different is, the utility model emery wheel is when saving the aluminium core retainer plate, increased a locking member that removably connects with the aluminium core cap, therefore, when the emery wheel after the wearing and tearing need be changed, the user only needs locking member is pulled down, the circular disk body that will need then to change is taken out replacing and is got final product, in other words, the aluminium core assembly in the utility model emery wheel can repeat to use, thereby has saved use cost greatly.

Fig. 2 is the sectional structure schematic diagram of edge " A-A " line among Fig. 1;

Fig. 3 is the decomposition texture schematic diagram of the utility model emery wheel.

The specific embodiment:

Below in conjunction with the drawings and specific embodiments the utility model emery wheel is described further:

As Fig. 1, Fig. 2 and shown in Figure 3, in this specific embodiment, the utility model emery wheel comprises circular disk body 4 and aluminium core assembly, circular disk body 4 centers have through hole 11, the aluminium core assembly comprises a locking member, aluminium core cap 3 and the nut 2 that is positioned at aluminium core cap 3 tops, aluminium core cap 3 is positioned at circular disk body 4 tops, the inner chamber top of nut 2 is connecting thread hole 1, the inner chamber bottom of nut 2 be one with aluminium core cap 3 centre bores, 10 identical sizes and the locating hole 5 that communicates, the diameter of locating hole 5 is greater than the big footpath in connecting thread hole 1, locking member is by forming for holistic chassis 7 and the lock sleeve 6 that is connected 7 tops, chassis, lock sleeve 6 tops are positioned at locating hole 5, lock sleeve 6 bottoms are positioned at through hole 11, chassis 7 is positioned at circular disk body 4 bottoms, the inner chamber top of lock sleeve 6 is locking screw pit 9, and the big footpath of locking screw pit 9 equals the big footpath in connecting thread hole 1, and 7 centers, chassis have one can be for the hexagon through hole 8 of die nut (not shown) insertion.

When the utility model emery wheel uses, can by connecting thread hole 1 aluminium core cap 3 be connected on the abrasive machine rotating shaft (not shown) earlier, circular disk body 4 is installed then, by locking screw pit 9 locking member is connected circular disk body 4 bottoms at last, and utilizes die nut that locking member is tightened on the abrasive machine rotating shaft.
