Abstract

The utility model discloses a grinding disk for a grinder, which comprises a disk body (3), wherein a shaft hole (4) for connection with a motor driving shaft is formed on the disk body (3); cutter mounting holes for mounting a cutter are formed on the disk body (3); the cutter mounting holes are divided into three groups; the first group of the cutter mounting holes comprises a plurality of trapezoid through holes (1) uniformly distributed along a circumferential direction; the second group of the cutter mounting holes comprises a plurality of threaded through holes I (2) uniformly distributed along a circumferential direction; the third group of the cutter mounting holes comprises a plurality of threaded through holes II (5) uniformly distributed along the circumferential direction; the threaded through holes I (2) are formed near the trapezoid through holes (1); the radial distance from the trapezoid through holes (1) to the center of the disk body (3) is longer than that from the threaded through holes II (5) to the center of the disk body (3); and the radial distance from the threaded through holes I (2) to the center of the disk body (3) is longer than that from the threaded through holes II (5) to the center of the disk body (3). In the grinding disk for the grinder, a cutter is more convenient to exchange.

Description

The grinder mill

Technical field:

The utility model relates to a kind of mill, specifically is a kind of grinder mill.

Background technology:

Grinder of the prior art generally all is to be disc-shape with mill, during work, rotate by the high speed of mill and to drive the cutter that is connected on the mill, make cutter relatively surface to be machined relatively rotate, cutter then can rub with surface to be machined in the rotation process, and then realizes the grinding to surface to be machined.In above-mentioned process of lapping, can reach different grinding effects, as fineness being required than higher finished surface or specially increasing surface roughness to increase coating adhesion, avoid the surface that coating flakes or only remove the machined surface etc. of the old lacquer in ground, above-mentioned various effect all is to be processed by specific cutter, for this reason, the user will constantly change the cutter on the mill in process usually, to satisfy different finished surface requirements, but, because described mill generally all only is furnished with a cutter, therefore cause the user when changing cutter, to have to very heavy mill is also unloaded together, and then other cover mill and a cutter loaded onto, operate and so forth to process and bring very large trouble when different surfaces need be changed different cutters to the user.

The utility model content:

The technical problems to be solved in the utility model is that a kind of convenient grinder mill of cutter of changing is provided.

Technical solution of the present utility model is, a kind of grinder mill with following structure is provided, and it comprises disk body; Described disk body is provided with and is used for the axis hole that is connected with motor driving shaft; Described disk body is provided with the cutter installing hole that is used for mounting cutter; Described cutter installing hole has three groups; First group of cutter installing hole comprises that several are along circumferential equally distributed trapezoidal hole; Second group of cutter installing hole comprises that several are along circumferential equally distributed tapped through hole I; The 3rd group of cutter installing hole comprises that several are along circumferential equally distributed tapped through hole II; Described tapped through hole I is positioned at the trapezoidal hole next door; The radial distance of described trapezoidal hole and disk body core is greater than the radial distance of tapped through hole II and disk body core; The radial distance of described tapped through hole I and disk body core is greater than the radial distance of tapped through hole II and disk body core.

After adopting above structure, compared with prior art, the utlity model has following advantage: only to be furnished with a cutter different with mill of the prior art, because the utility model is provided with three groups of cutter installing holes that are used for mounting cutter on described disk body, therefore, the utility model can utilize these three groups of cutter installing holes to be equipped with dissimilar cutters, thereby make the utility model when processing has different require surperficial, only needing to change corresponding cutter gets final product, need not again the mill of heaviness is carried out dismounting together, and then the operation when making things convenient for the utility model to change cutter greatly.

The specific embodiment:

The utility model is described in further detail below in conjunction with the drawings and specific embodiments:

As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, in this specific embodiment, the utility model grinder comprises disk body 3 with mill; Described disk body 3 is provided with three and is used for the axis hole 4 that is connected with motor driving shaft 10, and described three axis holes 4 evenly distribute along disk body 3 is circumferentially equidistant; Described disk body 3 is provided with the cutter installing hole that is used for mounting cutter; Described cutter installing hole has three groups, and first group of cutter installing hole comprises eight along disk body 3 circumferential equally distributed trapezoidal holes 1; Second group of cutter installing hole comprises six along disk body 3 circumferential equally distributed tapped through hole I2; The 3rd group of cutter installing hole comprises three along disk body 3 circumferential equally distributed tapped through hole II5.Described tapped through hole I2 is positioned at trapezoidal hole 1 next door; The radial distance of described trapezoidal hole 1 and disk body 3 cores is greater than the radial distance of tapped through hole II5 and disk body 3 cores; The radial distance of described tapped through hole I2 and disk body 3 cores is greater than the radial distance of tapped through hole II5 and disk body 3 cores.

In this specific embodiment, described disk body 3 is connected with three types cutter, and this cutter of three types is respectively cutter I6, cutter II8 and cutter III9.As shown in Figure 2, described cutter I6 has eight, and every cutter I6 is all matched with trapezoidal hole 1 by the trapezoid boss (not shown) of bottom, during work, be stuck in tightly in the trapezoidal hole 1 under the action of centrifugal force that trapezoid boss can produce when disk body 3 rotations, thereby cutter I6 can be fixed on the disk body 3 firmly.As shown in Figure 3, described cutter II8 has six, every cutter II8 all is connected on the disk body 3 by screw, flat shim and tapped through hole I2, and every being equipped with broach shell 7 between cutter II8 and the disk body 3.As shown in Figure 4, described cutter III9 has three, every cutter III9 all is connected on the disk body 3 by screw, flat shim and tapped through hole II5, and every being equipped with broach shell 7 between cutter III9 and the disk body 3.As shown in Figure 5, the utility model generally is mounted in grinder frame 11 front bottom end, and its operation principle is same as the prior art, also is to carry out work under the driving of motor driving shaft 10, so do not repeat them here.
