Problems solved by technology
For many shaft parts, the runout requirement of the outer circle of the end is not very high. If the internal grinding machine uses a three-jaw chuck to clamp the shaft parts and grind them, then this situation will easily lead to poor processing quality of the inner circle of the workpiece. , can not meet the process requirements

The invention relates to the field of machine tool accessories, in particular to a transmission mechanism of a grinding machine. The transmission mechanism comprises a connecting disc and a circular-tube-shaped connector; the connecting disc and the connector are connected into a whole through a universal joint structure; a moving ring is arranged on the connector; a pushing ring for driving the moving ring to move is connected to the connector in a threaded mode; through holes penetrate through the connector in the radial direction; the through holes are evenly distributed in the circumferential direction of the connector; arc-shaped clamping blocks slide in the through holes; bevel-shaped connecting rods are hinged between the outer sides of the clamping blocks and the outer side of the moving ring; a partition plate is arranged on the inner side of the connector in the radial direction of the connector; a plurality of conical blocks are glidingly connected to the partition plate in the radial direction; the conical blocks are evenly distributed in the circumferential direction of the partition plate; a connecting block is fixed to the center of the moving ring; and a push-pull rod is hinged between one end of each conical block and the connecting block. The transmission structure of the grinding machine can adapt to outer circle run-out of shaft parts, so that the machining quality of the grinding machine on the shaft parts is guaranteed.
Description
technical field [0001] The invention relates to the field of machine tool accessories, in particular to a grinding machine transmission mechanism. Background technique [0002] The internal grinding machine is mainly used for grinding the surface of the inner hole and the end surface of the cylindrical, conical or other shapes. The headstock of the internal grinder drives the workpiece to rotate, that is, the outer circle of the workpiece is usually clamped by a three-jaw chuck to realize the synchronous rotation of the headstock of the internal grinder and the workpiece. This clamping method has high requirements for the beating of the outer circle of the workpiece. The runout to the circle should not be too large. For many shaft parts, the runout requirement of the outer circle of the end is not very high. If the internal grinding machine uses a three-jaw chuck to clamp the shaft parts and grind them, then this situation will easily lead to poor processing quality of the ...
