Abstract
A working device of a noncircular workpiece, such as a piston of an internal combustion engine, is improved. A workpiece 10 is held by a work spindle and rotated. A noncircular working device 100 has a noncircular working unit base 110 and is provided with a servo motor 104. A noncircular working unit 120 is positioned along a Y axis, and an arbitrary cutting tool 133 is selected from a cutting tool group 130. A servo motor 112 reciprocates the noncircular working unit 120 on an X2 axis in synchronization with the rotation of the work spindle and performs noncircular working of the workpiece 10.
Claims5
A working device having a work head provided with a work spindle which rotates a workpiece and a noncircular working device,
- the noncircular working device, comprising:
- a noncircular working unit provided with multiple cutting tools;
- a noncircular working unit base which slidably supports the noncircular working unit along a radial axis line of the workpiece;
- a motor for noncircular working which is attached to the noncircular working unit base and reciprocates the noncircular working unit;
- and
- means for positioning the noncircular working unit base along an axis line orthogonal to the radial axis line of the workpiece.
A working device having a work head provided with a work spindle which rotates a workpiece and a noncircular working device,
- the noncircular working device, comprising:
- a noncircular working unit provided with multiple cutting tools;
- a noncircular working unit base which slidably supports the noncircular working unit along a radial axis line of the workpiece;
- a motor for noncircular working which is attached to the noncircular working unit base and reciprocates the noncircular working unit;
- and means for positioning the noncircular working unit base along an axis line orthogonal to the radial axis line of the workpiece,
- wherein the cutting tools mounted on the noncircular working unit are constituted by groups of multiple cutting tools which are attached parallel to a moving direction of the noncircular working unit base.
A working device having a work head provided with a work spindle which rotates a workpiece and a noncircular working device,
- the noncircular working device, comprising:
- a noncircular working unit provided with multiple cutting tools;
- a noncircular working unit base which turnably supports the noncircular working unit;
- a motor for noncircular working which is attached to the noncircular working unit base and reciprocates the noncircular working unit;
- and means for indexing the noncircular working unit base around an axis line parallel to the axis line of the workpiece,
- wherein the cutting tools mounted on the noncircular working unit are constituted by groups of multiple cutting tools which are attached radially to a turning direction of the noncircular working unit base.
