It is respectively provided with the upper pinch rollers group mechanism that workpiece upper surface is compressed corresponding to circular ring type rolling ring above two optical axises, described upper pinch rollers group mechanism includes clamping arm, clamping arm front end is provided with two pinch rollers, two pinch rollers are arranged side by side and make intermediate formation one compress chamber, clamping arm rear portion is provided with the cylinder for driving clamping arm to lift, clamping arm rear end is connected by rotating shaft a support bar, support bar lower end is provided with guide rail, guide rail is fixed on base, makes workpiece radially location by mobile upper pinch rollers group mechanism and circular ring type matching rolling ring.

One for technique scheme is improved by: for preventing flexural deformation, further respectively has auxiliary in the lower section of described two optical axises and supports seat, and auxiliary supports seat and is made up of bearing and the roller that is fixed on bearing, and roller contacts with the periphery of optical axis.

Beneficial effect:

This utility model longaxones parts quenching/tempering machine tool clamping rotary drive mechanism, is improved by structure, it is possible to be supported workpiece simultaneously, clamp and rotation process；The tailstock being made up of locking unit and sliding unit by setting, making mechanism's flexible adjustment convenient, clamping is stable, it is achieved that steel pipe part inner and outer pipes impewdance matching long to different size, tempering add the fast clamp location in man-hour, effectively improve processing technique, improve working (machining) efficiency and quality.
