Abstract

The utility model discloses a cutter mounting structure of building material equipment, in particular to a cutter mounting and fixing structure of a floor polishing machine. The cutter mounting structure consists of a screw, a protruding positioning column and a magnet; wherein, the protruding positioning column and the magnet are arranged on a grinding disc body; the screw is arranged on a cutter and in the position corresponding with the protruding positioning column; the screw is slightly larger than the protruding positioning column; and the magnet is pre-buried and embedded on the grinding disc body. When the utility model is installed, the protruding positioning column is inserted into the screw on the cutter, and the cutter is absorbed on the grinding disc body under the absorption effect of the magnet. When the utility model is disassembled, the cutter can be directly pried from the grinding disc body. The utility model has the advantages of simple structure, convenient installation and easy promotion.

Description

A kind of cutter mounting structure of building equipment

Technical field

The utility model relates to a kind of cutter mounting structure of building equipment, is meant the mount fixing structure of the cutter of building material machineries such as a kind of terrace sanding machine especially.

Background technology

On plant equipment such as sanding machine, for ease of changing mill or prolonging sanding machine service life, generally adopt compound mill structure, Chinese patent (CN2161417Y) promptly discloses this compound mill structure.This compound mill structure is that the mill that will be connected with motor improves design, is made of mill body that is connected with motor and the cutter that is fixed on the mill body.When improved like this advantage is to change mill, only needs to change the cutter that is fixed on the mill body and get final product, comparatively convenient.

At present, cutter is fixed on the mill body the general screw that adopts fixes, the deficiency of this fixed form maximum is: when changing cutter, need every screw unscrewed and cutter could be taken off after taking off, behind the cutter changing, also need every screw is tightened again, take time and effort very much.Even more serious is that screw is for a long time stressed may to cause its distortion, just at this moment screw is unscrewed difficulty more.In a word, being screwed cutter is not a kind of desirable mode.

Summary of the invention

It is a kind of time saving and energy saving that the purpose of this utility model is to provide, the cutter mounting structure of being convenient to remove and install.

For realizing the purpose of this utility model, intend by the following technical solutions:

A kind of cutter mounting structure of building equipment on the mill body that is connected with motor, is provided with projection reference column and magnet, with the corresponding position of reference column screw is set on cutter.

Described magnet is pre-buried being embedded on the mill body, and the projection reference column is fixed on the mill body.

Described screw is more bigger than the projection reference column on the mill body.

The design's principle is: in working order down, the mill body rotates at a high speed, and the force direction that is subjected to that is fixed on that the mill body fixes a cutting tool is along the direction of rotation of mill, and is stressed bigger, thereby adopts the reference column of projection to insert fixed cutting tool in the screw on the cutter.And on the direction perpendicular to the mill body, cutter is stressed less, thereby adopts magnet just cutter can be fixed.

Compared with prior art, the utlity model has following technological progress:

1,, during dismounting, directly cutter is levered up and to take off with screwdriver etc. because cutter is suction-operated by magnet that cutter is adsorbed on the mill body; During installation, cutter is adsorbed onto promptly finishes installation on the mill body.

2, because screw is slightly larger than the projection reference column, be out of shape even if the projection reference column is stressed for a long time, also be unlikely in the screw that is stuck in cutter, can not influence removing and installing of cutter.

Description of drawings:

Fig. 1 is example structure figure of the present utility model.

Fig. 2 is the mill body vertical view of the utility model embodiment.

Fig. 3 is the cutaway view of the A-A ' part of Fig. 2.

Label among the figure is: 1: screw; 2: the projection reference column; 3: magnet; 4: cutter; 5: the mill body;

The specific embodiment

Fig. 1 has illustrated the structure of embodiment of the present utility model, the pre-buried magnet 3 of inlaying on mill body 5, and projection reference column 2 is set, and on cutter 4, screw 1 is set with the projection reference column 2 corresponding positions of mill body 5, and screw 1 is more bigger than projection reference column 2.During installation, allow projection reference column 2 insert screw 1 on the cutters 4, and cutter 4 is adsorbed on the mill body 5, promptly finished the installation of cutter 4 by the suction-operated of magnet 3.During dismounting cutter 4, directly it is got final product down from mill body 5 sleds.

Fig. 2 has illustrated the vertical view of mill body 5 of this embodiment, and on mill body 5, the mill body part of the fixed structure that is combined to form by projection reference column 2 and magnet 3 is distributed on the mill body 5.

Fig. 3 is the cutaway view of the A-A ' part of Fig. 2, one end of projection reference column 2 is fixed on the mill body 5, the other end is to outer process, should guarantee, the height of projection reference column 2 is slightly less than the thickness of cutter 4, after soon cutter 4 was fixed on the mill body 5, during cutter 4 contact work packages, projection reference column 2 can not touch work package.Magnet 3 is pre-buried being embedded on the mill body 5, and outwards not outstanding.

For increasing the service life, described magnet 3 is permanent magnet.
