Abstract

The utility model relates to a combined grinding tool for superhard grinding material, particularly a tangent wheel and a bowl wheel used for grinding stone and ceramic. The combined grinding tool for superhard grinding material of the utility model is composed of a powder material layer and a base body, wherein the base body is combined and is formed by the fixed connection of a core sleeve with a convex table and a core plate with a concave table by a press plate and bolts. Because the base body of the utility model adopting the structure is combined, the core sleeve is replaced and the core plate does not need to be replaced when the material layer of the grinding tool is consumed, therefore the manufacture cost and the material cost of the core plate can be saved. The utility model is particularly suitable for the tangent wheel and the bowl wheel of large size.

Description

A kind of combined type superhard abrasive material grinding tool

Technical field

The utility model relates to a kind of superhard abrasive material grinding tool.

Background technology

Used superhard abrasive material grinding tool, connect to form by powder layer and matrix two partial fixings, matrix is an integral body, matrix is provided with the locating hole that is complementary with use equipment, the grinding tool of this structure, because matrix is fixedlyed connected with powder layer and is integral, powder is finished using, and whole grinding tool is then scrapped together, so waste is serious, especially the tangent of grinding stone material and pottery is taken turns and the bowl wheel, the volume of matrix account for tool whole grinding tool at least half because volume is big, supplies consumption is many, then waste even more serious, though some unit carries out the matrix recycling for saving, need handle the residual diamond bed of material when using because of reclaiming, add freight charges again, the manpower and materials of saving are limited.

The utility model content

The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of energy economical with materials and human cost and grinding tool easy for installation are provided.

The purpose of this utility model is achieved through the following technical solutions:

A kind of combined type superhard abrasive material grinding tool, comprise powder layer and matrix, the assembly that described matrix is made up of the central layer of fixedly connected equipment and the core retainer plate that is connected with powder layer, described central layer excircle is provided with " L " type concave station, described core retainer plate inner periphery is provided with the boss that matches with concave station, concave station and boss are the axial height K of the axial height H of matched in clearance and boss more than or equal to concave station in the axial direction, and the mating surface of pressing plate, concave station and boss by compressing boss between central layer and core retainer plate and being threaded is fixedlyed connected.

Describedly be threaded to being connected of the screwed hole that is provided with on the bolt that passes the through hole that is provided with on the pressing plate and the central layer.

Described being threaded to pressing plate made nut and passed the hole that is provided with on the central layer) the connection of bolts and nuts.

Fixedly connected between described pressing plate and central layer by pin.

Described powder layer is positioned at the grinding tool end face.

Described powder layer is positioned at the grinding tool circumferential surface

Adopt the grinding tool of the utility model structure, since matrix adopting the split-type structural of forming by central layer and core retainer plate, be connected with concave station, pressing plate, bolting by the boss that is provided with on it between central layer and core retainer plate, central layer is fixed on the axle of machine, when the loss of the grinding tool bed of material finishes, connecting bolt only need come loose, take off and have the core retainer plate that remains the bed of material, change the new grinding tool that does not have central layer of a slice again and get final product work, and central layer can be reused, so saved manufacturing and the Master Cost and the labour cost of grinding tool central layer, saved on transport costs and easy to operate.

The utility model is further introduced below in conjunction with accompanying drawing:

Fig. 2 is for adopting the bowl wheel schematic diagram of the another kind of structure of the utility model;

Fig. 3 is for adopting the utility model structure tangent wheel schematic diagram;

Fig. 4 is Fig. 3 vertical view;

Fig. 5 is for adopting the another kind of tangent wheel schematic diagram of the utility model structure;

The specific embodiment

Grinding tool of the present utility model is mainly used in the grinding of stone material and ceramic tile limit portion, especially it is bigger to be fit to volume, the grinding tool that the matrix materials are more, take turns as tangent, the bowl wheel, flat wheel and face wheel, as Fig. 1,3, shown in 5, the utility model grinding tool comprises powder layer 1 and the matrix that is matched and formed by central layer 3 and core retainer plate 2, central layer 3 is provided with the locating hole of fixedlying connected with device therefor, its excircle be provided with core retainer plate 2 inner peripherys on " L " type concave station 4 of matching of the boss 7 that is provided with, concave station 4 and boss 7 are matched in clearance and the boss 7 axial lengths axial length more than or equal to concave station 4 in the axial direction, central layer 3 passes through concave station 4 and boss 7 mating surface 8 diametrically with core retainer plate 2, bolt 5 and the pressing plate 6 that is pressed on the boss 7 are fixedly connected, for guaranteeing that boss 7 cooperates closely with the radially faying face 8 of concave station 4, prevent that central layer 3 and 2 of core retainer plates relatively rotate in the work, the axial length H of preferred boss 7 is greater than the axial length K of concave station 4, can guarantee to compress boss 7 by the rightabout active force of pressing plate 6 and mating surface 8 like this, increase the cooperation intensity of 2 of central layer 3 and core retainer plates; During installation, the B face is a locating surface, and central layer 3 is fixed on the device therefor, core retainer plate 2 is enclosed within on central layer 3 excircles, makes boss 7 embed concave station 4, presses pressing plate 6, tight a bolt and 5 get final product, when changing grinding tool, only need unclamp bolt 5, move lower platen 6, extraction has the core retainer plate 2 of the remaining bed of material, change new core retainer plate 2 and get final product, because central layer 3 and 2 of core retainer plates are matched in clearance in the axial direction, it is very convenient therefore to load and unload grinding tool.As shown in Figure 2, pressing plate 6 can be designed to the nut of bolt 5, bolt 5 passes the hole 9 that is provided with on the central layer 3 and is connected with nut 10, when pressing plate 3 is circle, is convenient the installation, and pressing plate 6 and central layer 3 are located by connecting by pin 11.
