Abstract
The utility model discloses the anti-eccentric fastening and loading device of a kind of blade grinder, comprise ring flange, ring flange is provided with and fixedly clamps axle and replaceablely clamp axle, the center of circle of described ring flange is provided with a deep hole, the described axle that fixedly clamps is fixed on the center of circle of deep hole, fixedly clamp on axle and be also equipped with a spring, the described replaceable axle that clamps comprises the portion that clamps of plate-like and the axis body of taper, the described portion that clamps and axis body are provided with a through through hole clamping portion and axis body, blue dish with deep hole is the center of circle also circular array show many magnetic posts, the utility model can improve, stablize VC machine periphery grinding radial run-out precision, thus the service life of the saw blade processed is reached unanimity.
Description
Technical field
The utility model relates to the anti-eccentric fastening and loading device of blade grinder.
Background technology
Ferrous materials cutting is large by saw blade cuts power, and when eccentricity value is large, service life can reduce, the mode that clamps of usual Japanese import VC blade grinder is at saw blade centre bore by the replaceable axle mount that is installed, locking saw blade to be processed is clamped again with ring flange, behind grinding periphery, radial run-out is at 0.03-0.04mm, the replaceable axle that clamps of this fastening and loading device is column, inevitably gap is there will be when being therefore installed and between saw blade centre bore, again because VC blade grinder adopts centralized positioning grinding, locating shaft and centre bore adopt interference fits tolerance, along with the difference of saw blade centre bore precision, after grinding, radial run-out precision is not quite similar, when causing saw blade to use there is larger difference in the life-span.
Utility model content
The utility model object is to overcome above-mentioned the deficiencies in the prior art, provides a kind of blade grinder anti-eccentric fastening and loading device, to improve, to stablize radial run-out precision during grinding saw blade.
The technical solution of the utility model is: the anti-eccentric fastening and loading device of a kind of blade grinder, comprise ring flange, ring flange is provided with and fixedly clamps axle and replaceablely clamp axle, the center of circle of described ring flange is provided with a deep hole, described fixedly clamp on the center of circle that axle is fixed on deep hole and to extend deep hole outside, fixedly clamp on axle and be also equipped with a spring, described spring is positioned at deep hole, the described replaceable axle that clamps comprises the portion that clamps of plate-like and the axis body of taper, the described portion that clamps and axis body are provided with a through through hole clamping portion and axis body, internal diameter and the equal diameters fixedly clamping axle of described through hole, the described diameter in the portion that clamps and the equal diameters of deep hole, replaceable clamp axle sleeve put fixedly to clamp on axle and hold out against by spring, ring flange with deep hole is the center of circle also circular array show many magnetic posts, many described magnetic posts are inserted in the fixing hole on ring flange, the top of magnetic posts and the end face of ring flange flush.
The described portion that clamps and axis body are formed in one structure.
Described through hole two ends are inclination angle transition with the end face clamping portion and axis body respectively.
Described magnetic posts has the six roots of sensation.
The beneficial effects of the utility model are: during the utility model converted products, sucked by ring flange magnetic force after being installed on saw blade centre bore by the replaceable axle that is installed, because the replaceable axle that is installed can slide on the axle that is fixedly installed, be installed saw blade time, because replaceable axis of the present utility model is taper, the replaceable axle that is installed is moved by the magnetic force of spring and ring flange, saw blade is made to be installed on the be installed shaft position identical with center hole size, thus avoid replaceable being installed between axle and saw blade centre bore to have gap, and then the radial run-out precision reduced when periphery is ground, by the change of the above-mentioned mode that is installed, VC machine periphery can be made to grind radial run-out stable accuracy within 0.03mm.
