Abstract
The utility model discloses a grinding disc. The grinding disc comprises a metal base disc and a grinding layer. A rotating shaft location hole is formed in the lower surface of the metal base disc. The grinding layer is composed of an iron sheet layer and a grinding material layer, the grinding material layer is attached to one side surface of the iron sheet layer, and the other side surface of the iron sheet layer is connected and fixed with the upper surface of the metal base disc. The grinding disc has the advantages that the grinding layer of the grinding disc and the metal base disc are detachably arranged, when the grinding disc is used, the grinding layer and the metal base disc are firmly connected through magnetic force, grinding operation can be carried out normally, when the grinding layer is damaged and needs to be replaced, the grinding layer only needs to be pried to be separated from the metal base disc and independently replaced, and therefore the grinding disc and a rotating shaft do not need to be disassembled, the grinding layer does not need to be removed, and the like. Replacement operation is convenient, time is saved, and replacement cost is saved.
Description
Technical field
The utility model relates to a kind of milling tools, particularly a kind of mill.
Background technology
Mill is a kind of common milling tools, according to the difference of mill size, and the workpiece of the different materials such as glass, metal, jewel that can be used for polishing.Existing mill structure is by plating, sintering, the method such as spray, cohere diamond, cubic boron nitride, corundum, carborundum or other abrasive material to be adhered in the Metal Substrate panel surface of circle, forms the mill layer, then mill is fixedly connected with rotating shaft.Mill is because long-term the use, mill layer will inevitably constantly wear and tear, after the mill layer is sharp, just do not need to change, and this mill layer and metal basal disc to be the mill of an integral body just need the whole mill of replacing, again the mill layer of loss is taken off and remove, again adhere to abrasive material and form new mill layer and could use.As seen this mill needs dismounting when changing, and is very inconvenient, and very large to the work for the treatment of amount of mill layer.
The utility model content
The utility model purpose: for the problems referred to above, the purpose of this utility model provide a kind of simple in structure, change easily mill, save cost and time.
Technical scheme: a kind of mill, comprise metal basal disc, mill layer, described metal basal disc lower surface offers the rotating shaft locating hole, described mill layer is comprised of iron sheet layer and abrasive material, described abrasive material is attached to described iron sheet layer one side surface, and described iron sheet layer opposite side surface is connected and fixed with the upper surface of described metal basal disc.
Described metal basal disc upper surface is provided with several fixing holes, places magnet in the described fixing hole, and the magnetic force of the upper surface of iron sheet layer opposite side surface and metal basal disc by magnet is fixed and is connected, connect reliably, and convenient disassembly.
Described fixing hole evenly distributes at the upper surface of described metal basal disc, and magnetic force evenly distributes, and makes metal basal disc and the fixation of iron sheet layer.
Described mill be shaped as discoid or the square plate shape.
Beneficial effect: compared with prior art, the mill layer and the metal basal disc that the utility model has the advantages that mill are detachable, and mill grinds layer and firmly is connected by magnetic force with the metal basal disc in use, normally carry out sanding operation, when mill layer wearing and tearing need to change, only need prize the mill layer it is separated with the metal basal disc, the mill layer is changed separately got final product, need not to dismantle mill and rotating shaft, take off except grinding layer etc., change operation easily, save time, save the cost of changing.
Description of drawings
Fig. 1 is the utility model structural front view;
Fig. 2 is the A-A view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 2.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
Shown in accompanying drawing 1-3, a kind of mill, comprise metal basal disc 1, mill layer, magnet 5, the lower surface of metal basal disc 1 offers the rotating shaft locating hole, the upper surface of metal basal disc 1 evenly distributes and has offered several fixing holes 4, and magnet 5 is positioned in the fixing hole 4, and the mill layer is comprised of iron sheet layer 2 and abrasive material 3, abrasive material 3 is attached to iron sheet layer 2 one side surface by plating, sintering, the method such as spray, cohere, and iron sheet layer 2 opposite side surface is connected and fixed by magnetic force with metal basal disc 1 upper surface.Offer quantity and the position of fixing hole 4 are connected and fixed needed suction size with the mill layer and arrange according to size, the metal basal disc 1 of mill.Mill be shaped as discoid or square plate shape or other shape.
Mill is fixedly connected with rotating shaft after finishing according to above-mentioned manufacturing, can carry out normal sanding operation.When abrasive material 3 losses of mill layer seriously need to be changed, prize the mill layer, weaken magnetic force, iron sheet layer 2 is separated with metal basal disc 1, namely detachable mill layer is changed the mill layer separately.Mill layer is made separately, for consumable accessory standing.
Claims (4)
1. mill, comprise metal basal disc (1), mill layer, described metal basal disc (1) lower surface offers the rotating shaft locating hole, it is characterized in that: described mill layer is comprised of iron sheet layer (2) and abrasive material (3), described abrasive material (3) is attached to described iron sheet layer (2) one side surface, and described iron sheet layer (2) opposite side surface is connected and fixed with the upper surface of described metal basal disc (1).
