Detailed Description
The utility model will be further described with reference to the drawings and examples.
As shown in fig. 1 to 3, a workpiece clamping device for a heavy deep hole scraping and rolling machine tool comprises a clamping seat 1 arranged on the outer circle of a workpiece, a body shell 2 is arranged on the upper part of the clamping seat 1, and a flange cover 3 is arranged at one end of the body shell 2. The worm shaft 4 is installed in a cavity a formed by the body housing 2 and the flange cover 3, and a rectangular spiral groove 41 is provided at the outer circumference of the worm shaft 4. The body housing 2 and the flange cover 3 are respectively provided with a round hole for positioning the worm shaft 4 in the circumferential direction, and two end surfaces of the worm shaft 4 are respectively provided with a plane bearing 5 for bearing the axial force received by the worm shaft 4. The steel strip 6 is provided with a plurality of grooves 61 arranged in parallel, the deflection angle of the grooves 61 is consistent with the helix angle of the helical groove 41, one end of the steel strip 6 is arranged on the clamping seat 1, and after the other end winds the periphery of a workpiece, the other end enters the cavity A along the guide groove on the clamping seat 1 and is meshed with the worm shaft 4. By rotating the worm shaft 4, the circumference around which the steel belt 6 and the clamping seat 1 are wound can be continuously reduced, and the excircle of the workpiece can be clamped. Because the steel belt 6 has flexibility, the outer circle of the workpiece can be closely attached everywhere finally, and reliable clamping is realized.
