Summary of the invention
The utility model is to provide a kind of eccentric angle can be in harmonious proportion the adjustable ball lapping mechanism of normal pressure, be used for solving existing " spheroid " geometric accuracy and surface roughness after grinding and often do not reach requirement, thereby cause the difficult quality technical problem up to standard of " ball valve ".
For achieving the above object, the technical solution of the utility model is: a kind of eccentric angle can be in harmonious proportion the adjustable ball lapping mechanism of normal pressure, comprise abrasive disk, abrasive disk rotating drive shaft, internal axle sleeve, lifting overcoat, be characterized in: abrasive disk rotating drive shaft is fixedly connected with internal axle sleeve, internal axle sleeve upper end is provided with and regulates and cap and stage clip adjustment cap, internal axle sleeve lower end is slidably connected by flat key II and lifting overcoat, between stage clip adjustment cap lower surface and lifting jacket bottom upper surface, holddown spring is housed; Lifting jacket bottom is fixedly connected with U-shaped, and U-shaped is connected with abrasive disk by universal joint.
Between internal axle sleeve and abrasive disk rotating drive shaft, by flat key I, be fixedly connected with internal axle sleeve hold-down screw.On internal axle sleeve cylindrical, have lifting overcoat link slot, lifting overcoat link slot is connected with the dog screw on lifting overcoat cylindrical.Lifting overcoat is connected with U-shaped by lifting overcoat link slot and U-shaped set bolt.
The beneficial effects of the utility model are;
(1) rotatablely moving of abrasive disk imported (Fig. 4) into by abrasive disk rotating drive shaft, by internal axle sleeve, lifting overcoat, lifting overcoat link slot, U-shaped, universal joint, reach abrasive disk, abrasive disk axis and vertical axis have departed from an angle drift angle a, and with this state departing from, around vertical axis, rotate, the movement locus of abrasive disk is similar to the motion of Ho La hoop;
(2) size of drift angle a is adjustable: unclamp U-shaped set bolt (Fig. 5), move U-shaped the position with respect to lifting overcoat, can adjust easily the size of drift angle a;
(3) to act on the normal pressure on spheroid be adjustable to abrasive disk: adjust and regulate and the high and low position of cap, stage clip adjustment cap, can change the elastic force of holddown spring, thereby change abrasive disk, act on the normal pressure on spheroid.
The utility model has changed the motion mode of abrasive disk, and the axis of abrasive disk self and rotation have departed from an angle drift angle a, and has the function of " eccentric angle can be in harmonious proportion abrasive disk adjustable to the normal pressure of spheroid ".It is adjustable that abrasive disk has departed from an angle drift angle a(angle with its axis and vertical axis) position, around vertical axis, rotate, comprehensively both motions, the result obtaining is: spheroid is around horizontal rotational shaft, abrasive disk is to be similar to the motion mode of " Ho La hoop ", around vertical axis, rotate, grinding track is good, and geometric accuracy and the surface roughness of spheroid after grinding is all significantly improved.
