Polishing machine
First Claim
1. A polishing machine for polishing the surface of a workpiece comprising:
- a base;
a driving shaft rotatably attached to the base;
a first surface plate rotatably attached to said base and provided with a plate surface, said first surface plate having a through-hole which the driving shaft is passed through;
a sun gear slidably connected to said driving shaft to slide in the axial direction of said driving shaft and provided with a projection enclosing said driving shaft, said projection extending along said driving shaft and having a threaded portion on an outer circumference thereof;
an internal ring gear on said base and arranged concentric with said sun gear and enclosing said sun gear;
a plurality of carriers arranged between said sun gear and said internal ring gear within the same plane, said carriers being in mesh with said sun gear and said internal ring gear, and lying on said first surface plate, each of the carriers having a plurality of through-bores in which the workpieces are housed;
a driving means for moving said internal ring gear to engage with or disengage from said carriers, and means for rotating said internal ring gear;
a sun gear actuating member attached to said driving shaft, limited of its movement in the axial direction, and provided with a threaded portion which is screwed onto the threaded portion of the projection of said sun gear which serves as a feed screw for adjusting the axial location of the sun gear relative to the carriers;
a second surface plate arranged apart from said first surface plate and provided with a plate surface which faces that of said first surface plate;
a second surface plate moving means for moving said second surface plate to approach and separate from said first surface plate; and
an abrasive member attached to the plate surface of at least one of said first and second surface plates to polish the surfaces of the workpieces.

Abstract
A polishing machine for polishing the surfaces of the workpieces to be processed has upper and lower surface plates which are rotated relative to each other. A plurality of carriers are placed between the upper and lower surface plates and each of the carriers has a plurality of bores into which the workpieces are fitted. These carriers are engaged with both the sun gear and the internal ring gear within the same plane. In account of the sun gear and the internal ring gear, the carriers are rotated round the sun gear, turning round their own axes. The internal ring gear can be lifted up and down by a lift mechanism. The sun gear is slidably attached to a hollow driving shaft and has a feed screw which is engaged with a feed nut. This feed nut is rotatably fitted onto the hollow driving shaft in such a way that the nut is limited of its movement in the axial direction. The sun gear can be lifted up and down independently of the internal ring gear when an operating means including the feed screw and nut is operated.
