Described emery wheel is rounded, and the periphery of the circle that emery wheel is in is the grinding surface of emery wheel, and described grinding surface circularizes, mill The longitudinal section of bevel is made up of arc surface, first conical surface and second conical surface, and the central angle of described arc surface is α, described α=90 °, Described first conical surface and plane of grinding wheel institute angle degree are β, described β=19 °, described second conical surface and plane of grinding wheel institute angle Spend for γ, described γ=56 °;
Further, described 3rd motor is contrary with the rotation direction of the first motor and the second motor.
Operation principle:
By collet, valve top is fixed, telescopic cylinder promotes slide block to drive the level shifting to the right of the first motor Dynamic, Valve Disc is resisted against on the locating piece of pressing plate, realizes being accurately positioned of valve, subsequent hydraulic lift is to moving down Dynamic, drive emery wheel to move down, realize the grinding to Valve Disc.
Beneficial effects of the present invention are:
A kind of Valve Disc high accuracy one-shot forming grinding attachment that the present invention provides, its structure is simple, reasonable in design, leads to Cross the first motor and collet and the second motor and pressing plate uses cooperatively and for valve to be fixed on horizontal level, more pass through locating piece Positioning it is ensured that the degree of accuracy of the fixed position of valve, by being applied in combination of hydraulic lift, the 3rd motor and emery wheel, Valve Disc is carried out with grinding, many quasi spline of the grinding surface of emery wheel and the angle requirement of grinding surface, can effectively lower The in order difficulty of processing of manufacturing procedure, carries out one-time formed ground to Valve Disc simultaneously, shortens technological process, And only need one-time positioning, greatly reduce cost of labor, also significantly improve production efficiency simultaneously, improve the essence of valve Degree.
