Problems solved by technology

[0003] The technical problem solved by the present invention is to provide a threaded soft three-claw suitable for turning and processing thin-walled sleeve parts, and connect the arc-plate type threaded connector of the soft three-claw body by screwing the inner thread of the compression nut The external thread of the external thread compresses the parts in the axial direction and clamps the parts radially, which solves the technical problems of easy deformation, slow clamping and inability to guarantee the processing accuracy of thin-walled sleeve parts in the prior art.

Abstract

A threaded soft three-claw is provided, which has a soft three-claw body, and the soft three-claw body is vertically fixed to an arc-plate type threaded connector with an axial height h>2 / 3h1, and the arc-plate type threaded connector is used for leaning on the support And it is suitable for the outer peripheral side wall of the thin-walled sleeve parts to be processed, wherein the arc plate type threaded connector is made of external threads, and the screw connection is made of internal threads and is the same as the central axis of the three-jaw chuck body The compression nut of the shaft axially compresses the thin-walled sleeve parts to be processed and at the same time radially clamps the thin-walled sleeve parts to be processed on the three-jaw chuck body. The invention has good anti-deformation effect of parts, high processing precision, low cost, convenient manufacture and simple operation.

Description

technical field [0001] The invention belongs to the technical field of three-jaw chuck claw tooling used for turning and processing thin-walled sleeve parts, and in particular relates to a threaded soft three-jaw. Background technique [0002] At present, when turning precision machining thin-walled sleeve parts 4 (see Figure 10-Figure 12 ), generally use fan-shaped soft three-jaws or design special fixtures to realize processing, but these two methods have different disadvantages. Among them, although the soft three jaws of the fan-shaped soft three-jaw chuck can radially clamp the thin-walled sleeve parts 4 with concentricity, due to the limited axial thickness of the fan-shaped jaw body, when the centripetal positioning is clamped, the clamping A slightly larger force will lead to plastic deformation of the part; and too small clamping force will cause the part to rotate relative to the three-jaw chuck under the action of cutting force; therefore, the existing fan-shaped...
