Above-mentioned eccentric wheel type emery wheel hole support fixture, also comprise rotating spanner, described rotating spanner comprises the sleeve being positioned at center, the outside of described sleeve is evenly distributed with support bar, the afterbody of described support bar is provided with bulb, the number of described bulb is identical with the number of pressing handle, and described rotating spanner is established on center shaft by jacket casing, and described bulb contacts with pressing handle.
Above-mentioned eccentric wheel type emery wheel hole support fixture, described sleeve is arranged with hook spanner and puts forth effort hole.
Above-mentioned eccentric wheel type emery wheel hole support fixture is matched in clearance between described sleeve and central shaft.
Above-mentioned eccentric wheel type emery wheel hole support fixture is matched in clearance between described eccentric wheel and alignment pin.
Above-mentioned eccentric wheel type emery wheel hole support fixture, described supporting base is stepped.
Above-mentioned eccentric wheel type emery wheel hole support fixture, described eccentric thickness is less than the thickness of emery wheel.
The beneficial effects of the utility model:
The utility model still adopts the mounting means of mandrel, and on the one hand, mandrel is provided with stair-stepping supporting base, and this stair-stepping setting can play distributed support power, and the beneficial effect avoiding stress to concentrate, makes it be more applicable for type horizontal processing machine tool; On the other hand, the utility model without flange, but adopts eccentric wheel with the emery wheel that is locked, be conducive to the carrying out of type horizontal processing machine tool cross grinding, and eccentric thickness is less than the thickness of emery wheel, so eccentric wheel can not cover part emery wheel, normal grinding work therefore can not be interfered.
Further, process to realize emery wheel clamped one time, end face and cylindrical, except guarantee emery wheel hole supports, also need the concentricity ensureing emery wheel hole and mandrel, therefore the utility model is also provided with rotating spanner simultaneously.Rotating spanner can drive all eccentric wheels to rotate simultaneously, rotational angle and radial displacement in the same size, realizes locking simultaneously, guarantees certain concentricity.Specifically, first adjust each eccentric initial angle, direction and radial displacement in the same size, then force rotates this rotating spanner, and rotating spanner is while rotation, and each bulb promotes to rotate with its corresponding pressing handle contacted, pressing handle band movable eccentric wheel rotates, after eccentric wheel rotates, produce displacement in radial direction, form radial load, thus support lock tight sand wheel, rotating backward this rotating spanner can unlock; Wherein, the angle that the angle that each bulb turns over all turns over rotating spanner is identical, so each pressing handle rotate angle also identical and be equal to each eccentric wheel rotate angle, the size of the radial displacement that each eccentric wheel is final is also identical thus, so the radial load of each eccentric wheel to emery wheel hole is identical, ensure that the concentricity of emery wheel hole and mandrel thus.
As can be seen here, radial displacement propping sand wheel bore after the utility model utilizes eccentric wheel to rotate, and utilize the frictional force in eccentric wheel and emery wheel hole to lock emery wheel, can realize emery wheel can being fixed without flange, and be applicable to type horizontal processing machine tool, in addition the utility model not only can ensure the concentricity of emery wheel hole and mandrel by the setting of rotating spanner, realizes emery wheel clamped one time, end face and cylindrical and processes simultaneously, and can easily clamping, dismounting emery wheel.
