Abstract

The utility model relates to a positioning and rotating device of a centreless grinding machine. The positioning and rotating device of a centreless grinding machine is provided with a machine seat. Two slide blocks which can relatively slide are arranged on the machine seat. The interiors of the slide blocks are respectively provided with one rotary shaft. The front ends and the rear ends of the rotary shafts are respectively provided with rotary wheels and driven gears. The original movable gear which is driven by a driving motor simultaneously acts on two driven gears to make two rotary wheels rotated in the same direction. The two rotary wheels are matched with a press rod to clamp a column-shaped work object in a three-point mode to drive the column-shaped work object to rotate to be ground. Due to the fact that the sizes of the outer diameters of work objects are different, when the wheel distance of the two rotary wheels is needed to be regulated, the wheel distance of the two driven gears is changed. The height of the driving motor together with the original movable gear is regulated, and the gear matching relation of the original movable gear and the driven gears is accurate.

Description

Aligning and rotating unit of centreless grinder

The utility model relates to a kind of location, tumbler of centerless lapping machine.

The location of the centerless lapping machine of prior art, tumbler see also shown in Fig. 1,2,3, and it mainly comprises:
