| 61 | Improved grinding machine and method of grinding | EP98102404.5 | 1995-04-20 | EP0846517A2 | 1998-06-10 | Laycock, Michael |
A method of grinding crankpins (56) of a crankshaft (54) wherein the machine is under computer control and the grinding wheel (40) is advanced and retracted under computer control so as to follow the planetary motion of the crankpin as the crankshaft rotates. This maintains grinding contact between the wheel and the pin to allow the grinding of the latter. The crankshaft is mounted between centres and is rotated by a drive unit (52, 46), drive being transmitted to the end of the crankshaft via a connecting means (10) which is torsionally rigid in a plane perpendicular to the axis of rotation of the crankshaft but which is readily deformable in other planes to accommodate misalignment and so as to decouple the crankshaft (54) from the drive (52,46) other than to transmit pure rotation to the crankshaft. |

| PURPOSE:To surely machine a tow-dimensional shaped groove and a projection with respect to the center of a disk in a chuck device which is installed on a numerically controlled milling board, etc. by holding a workpiece having the disk shaped portion in a centered condition. CONSTITUTION:A workpiece 7 is placed on a workpiece placing portion 5 with the positioning circular hole 72 thereof being fitted on a pin having a rhombic section. After that, a movable claw 3 is moved along an X axis to fix the workpiece 7 between fixing claws 4 and the movable claw 3. At this time, since the pin 6 is provided on the X axis of the X-Y axes the centers of which are the original point of the chuck 2, the rotation of the workpiece 7 will not take place during machining. As for the shape of the pin 6, the dimension in the direction conforming to the X axis is larger than the dimension in the direction perpendicular to the X axis, if the relative position to an end mill tool is conformed to the previously set original point of a computer program for controlling the center of the workpiece 7 with the center of the master workpiece, the shifting of center in the X axis direction can be suppressed to half the dispersion of the workpiece 7. | ||||||

| PURPOSE:To hold a center pin with high accuracy in spite of the clearance between a holding body and the center pin and prevent the lowering of accuracy caused by change with time by loosely fitting the center pin into the holding body having a pressure-oil storage groove and holding the center pin by means of the elastic deformation of the holding body. CONSTITUTION:As a workpiece 11 is fed, a draw screw 8 is drawn and a high pressure oil is fed into a storage groove 13 from a hydraulic pump prior to the completion of holding by a jaw 7. A holding body 12 is fitted into a holder 3 and surrounded by the whole periphery of a storage groove 13 on the inner peripheral face 14a of a fitting portion 14 forming a closed chamber, while the holder 3 is firmly formed in a body with a chuck body 2. Hence, the pressure of oil acts toward the axis of the holding body 12 and elastically deforms the bottom portion having a thin wall thickness (t), interposingly holding a loosely fitted center pin 4 and absorbing the clearance to carry out center adjustment for making the chuck body 2 agree with the axis of the center pin 4, thereby holding the workpiece 11 with high accuracy. | ||||||

| PURPOSE:To prevent the generation of chucking trouble even if a stop trouble is generated on a movable body by keeping a holding hook in an opened state until the movable body is allowed to reach an advance edge by the advance of a plunger and permitting the holding hook to be opened and closed only at the advance edge. CONSTITUTION:Even if a trouble which suspends the advance transfer of a movable body 7 generates during said transfer, the relative shift between a hook transfer body 45 and a plunger 39 is suppressed by the rigid engagement between the upper surface 45b in the rear edge part of the hook transfer body 45 and a closing regulating surface 51a, and the hook transfer body 45 and the plunger 39 keep an integral form, and the closing of a holding hook 47 except at an advance edge position is prevented. When the slip preventing ring 9 of the movable body 7 contacts a stepped part 3a, the movable body 7 is stopped at the advance edge, and the engagement between the upper surface 45b in the rear edge part and the regulating surface 51a is released. Then, the plunger 39 advances furthermore, and the flat surface guiding part 49a of a pin 49 is guided by the inclined surface 37 to a floating plunger 33, and shifts the rear part 45a of the hook transfer body outwardly in the radial direction, and the holding hook 47 is shifted to the center side, keeping a supporting shaft 43 as center, and the edge part of a work W is held. | ||||||
