Abstract
The utility model relates to a self-aligning grinding wheel. The utility model has the structure that the inner wall of a centre hole of the utility model is provided with one to twenty ring-shaped grooves, wherein the width of each groove is 0.5-100 mm, the depth of each groove is 1-200 mm, and the cross section of each groove is in an L shape, an n shape, a V shape, a U shape, a semicircle, a semiellipse shape, a sawtooth shape or the combination of all shapes. The outer diameter of each elastic ring is matched with each ring-shaped groove, the inner diameter of each elastic ring is smaller than the hole diameter of the centre hole of the grinding wheel, namely the shaft diameter of a standard main shaft within 0.05-10 mm, and each elastic ring is embedded in each ring-shaped groove. The grinding wheel is arranged on a main shaft; since each elastic ring is in an interference fit with the main shaft, each elastic ring is uniformly deformed, a gap between the centre hole of the grinding wheel and the main shaft is made up, the goal of automatically aligning the coaxiality of the centre hole and the main shaft is achieved, and the problem of the oversize of the radial runout of the outer circle surface of the grinding wheel during the operation of the grinding wheel is prevented. The maximum radial runout of the outer circle of the grinding wheel is only 0-0.02 mm according to a test. The effect that a diamond grinding wheel and the main shaft which are coaxal are used for the edge grinding of glass is achieved, and the edge chipping of the glass is avoided. The grinding wheel is also suitable for a grinding device which is processed by crisp and hard materials such as stone, ceramic, etc. The utility model has the advantages of simple structure and low cost.
Description
(1) technical field
The utility model relates to a kind of grinding wheel for grinding, is specially a kind of self-aligning grinding wheel.
(2) technical background
All to use emery wheel in the processing of crisp and hard materials such as glass, stone material, pottery.Emery wheel is mounted on the motor transmission shaft (being main shaft), and main shaft drives emery wheel rotation carrying out grinding operation.After emery wheel is assemblied on the main shaft, if big gap has been arranged between the centre bore of emery wheel and the main shaft, will make the coaxiality error of emery wheel and main shaft bigger than normal, the run-out error of periphery is also bigger than normal when having caused the emery wheel rotation.In the use of emery wheel, emery wheel on main shaft repeatedly the dismounting meeting main shaft is caused to a certain degree wearing and tearing, main shaft is diminished.When the deviation from circular from of main shaft, scale error are big in addition, also can cause the gap between main shaft and the emery wheel centre bore to strengthen.If glass edge-grinding machine is under these circumstances, the skive on it in use, conference bump glass is crossed in circular runout, causes glass to collapse the limit, becomes waste product.In addition, high-quality emery wheel has characteristics such as high-wearing feature, high efficiency, if be contained on the worn out main shaft, its offset is difficult to break-in, and it is more serious that glass collapses the limit, the high-quality emery wheel can not use, its high efficiency also can not get performance, can only use low-quality emery wheel, like this, not only have a strong impact on the production efficiency and the crudy of glass processing industry, also influenced the raising of emery wheel manufacturing enterprise technical merit and economic benefit simultaneously.In the processing of crisp and hard materials such as stone material, pottery also similar problem can appear.So the grinding industry presses for the problem of the quick levelling of axiality that solves emery wheel and main shaft, to improve grinding quality and efficient.
(3) utility model content
The purpose of this utility model is a kind of self-aligning grinding wheel of design, and this emery wheel is installed on the main shaft, can regulate the axiality of emery wheel and main shaft automatically, so that the circular runout of emery wheel its periphery when rotating is in allowed band.
The self-aligning grinding wheel of the utility model design, comprise that there is the emery wheel disk of centre bore at the center, 1～20 cannelure is arranged on the inwall in heart hole therein, the width of groove is 0.5mm～100mm, groove depth is 1mm～200mm, the elastic ring internal diameter that its external diameter matches with cannelure is standard main shaft diameter of axle 0.05mm～10mm less than emery wheel centre bore aperture, and external diameter is overgauge main shaft diameter of axle 2mm～400mm greater than emery wheel centre bore aperture, and elastic ring embeds in the cannelure.
This emery wheel is installed on the main shaft, and nut is fastening.Because the elastic ring and the main shaft that embed on the emery wheel inwall are interference fit, the homogeneous deformation of elastic ring has remedied the gap between emery wheel centre bore and the main shaft, makes the gap of emery wheel and main shaft be in uniform state, to reach the purpose of aligning its axiality automatically.
Self-aligning grinding wheel of the present utility model can effectively solve the axiality that emery wheel is installed on the non-type main shaft and align problem automatically, and the circular runout that prevents emery wheel its periphery in service is excessive.
Test: process the axle of the main shaft after the similar wearing and tearing, this self-aligning grinding wheel of installation on it, last jack panel.The operation conditions of simulate glass edge polisher clamps this axle with lathe pawl dish, rotates lathe pawl dish, checks the situation of beating of this self-aligning grinding wheel outer round surface with dial gauge.When the gap of axle and skive was 0～2mm, if use plain wheel, the periphery circular runout reached 0～2mm, and the self-aligning grinding wheel of the utility model design is installed, and it only is 0～0.02mm that its cylindrical maximum radial is beated.Reached the effect of glass edging with skive and edge polisher main shaft axiality, the glass of promptly having avoided producing therefrom collapses the limit.This self-aligning grinding wheel also is applicable to the grinding attachment of crisp and hard material processing such as stone material or pottery, and simple in structure, and cost is low, is easy to apply.
