Abstract

The utility model discloses a cutter mounting structure, comprising a cutter and a millstone body, wherein a magnet is embedded in the millstone body; the cutter comprises a tool bit and a base plate; a projecting positioning column is arranged on the base plate; and a hole is formed on the millstone body at a position corresponding to the projecting positioning column. The cutter mounting structure is characterized in that a lug extending outwards along the outer edge of the base plate is arranged on the base plate; a groove is formed at the outer edge of the millstone body and matched with the lug; a projection is formed at the center of the millstone body; and a notch is formed on the base plate at a position corresponding to the projection. The cutter mounting structure cannot cause loosening of the cutter and the millstone body due to deformation of the projecting positioning column or unstable attraction of the magnet; the connection between the cutter and the millstone body is firmer; the pressure of the projecting positioning column is reduced; and the service life of the cutter is prolonged.

Description

A kind of cutter mounting structure

Technical field

The utility model relates to the technical field of structures of the training equipment of polishing, particularly a kind of cutter mounting structure.

Background technology

In Architectural Equipment, often can use grinding machine.For the ease of changing mill, generally take the structure of compound mill.In the prior art, (publication number is: CN201313276Y) disclose a kind of cutter mounting structure of building equipment, it is fixed on cutter on the mill body through magnet and projection reference column Chinese patent, when dismounting, cutter is levered up and can take off.This technology has realized effect for convenience detach; But only fix cutter and mill body through magnet and projection reference column; The mill body connects motor and tells when object is polished in rotation; Be easy to cause the distortion of projection reference column, may cause becoming flexible between cutter and the mill body, service life is also corresponding low.

The utility model content

It is a kind of simple in structure that the purpose of the utility model is to provide, and is connected firmly, the cutter mounting structure that conveniently unloads, increases the service life.

For realizing the purpose of the utility model, adopt following technical scheme:

A kind of cutter mounting structure comprises cutter and mill body, is inlaid with magnet on the mill body; Cutter includes cutter head and base plate, and the projection reference column is arranged on the base plate, and position corresponding with the projection reference column on the mill body is provided with the hole; It is characterized in that: have on the said base plate along the base plate outer rim to overhanging ear, the outer rim of mill body is provided with groove, and groove matches with ear; There is convexity at the center of mill body, and the position of respective protrusions is provided with breach on the base plate.

Further, cutter head is installed on the ear of base plate.

When the utility model is installed; With do not install in the cutter cutter head one facing to the mill body; Hole on the corresponding mill body of projection reference column, the magnet on the mill body firmly adsorbs base plate, and the projection reference column inserts aerial on the mill body; Ear on the base plate snaps in the groove on the mill body, and the convexity at mill body center is passed the breach of relevant position on the base plate.Cutter is connected through above-mentioned structure with the mill body, and both fix.The part of cutter head is given prominence to above the mill body, and when mill body connection motor rotated at a high speed, cutter head was accomplished polishing work.

Compared with prior art, the utility model has following advantage:

The first, the installation of cutter and mill body is with fixing more firm.Except magnet and projection reference column fixing, the ear on the groove fit base plate of mill body, the disk on the mill body cooperates the circumferential notch on the base plate, and cutter and mill body are effectively engaged.When mill body connection motor rotates at a high speed, can not worry to become flexible because of the projection reference column is out of shape not firm cutter and the mill body-fixed of causing of perhaps magnet absorption.

The second, multiple fixed form can alleviate the pressure of projection reference column.When mill body connection motor rotates at a high speed; Centrifugal force is bigger, relies on magnet and projection reference column to fix the scheme of cutter and mill body in the prior art, inevitably can cause the quick distortion of projection reference column; The mode that the utility model quadruple is fixing; Can effectively slow down the pressure of projection reference column, protection projection reference column increases the service life.

The specific embodiment

Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and embodiment.

In conjunction with Fig. 1, Fig. 2 and Fig. 3, the utility model relates to a kind of cutter mounting structure, comprises cutter 1, mill body 2; Cutter 1 comprises base plate 11 and cutter head 12; Have on the base plate 11 along its outer rim to overhanging ear 111, cutter head 12 is welded on the ear 111, and projection reference column 112 is located on the base plate 11; Mill body 2 is inlaid with magnet 21, and mill body 2 is being provided with hole 22 with projection reference column 112 corresponding positions; The outer rim of mill body 2 is provided with groove 23, and there is convexity 24 at the center, with protruding 24 corresponding positions a breach 113 is arranged on the base plate 11; Groove 21 matches with ear 111, and protruding 24 match with breach 113.During installation; Over against mill body 2, in the hole 22 that projection reference column 112 inserts on the mill bodies 2, the ear 111 on the base plate 11 snaps in the groove 23 with the one side of cutter 1 no cutter head 12; In the breach 113 that convexity 24 snaps on the base plate 11, accomplish cutter 1 and fix with being connected of mill body 2.In use; The utility model can not take place because of distortion of projection reference column or not firm cutter and the loosening situation of mill body-fixed of causing of magnet absorption; Cutter is connected more firm with the mill body, slowed down the pressure of projection reference column, has prolonged the service life of cutter.

Claims
