Abstract

The invention provides a precision excircle turning clamp for a thin-wall flange. The precision excircle turning clamp comprises a chuck mounted on a machine tool, and a plurality of clamp bodies which are annularly arrayed along the axial direction of the chuck and are fixed on the chuck through threaded fasteners, wherein each clamp body comprises a clamping block with one end fixed on the chuck through the corresponding threaded fastener and the other end being an arc curved surface, and two pressing plates which are respectively located on two sides of the corresponding clamping block and are fixed on the clamping block through the threaded fasteners. According to the precision excircle turning clamp, provided by the invention, for the thin-wall flange, the thin-wall flange is circumferentially located by the clamping blocks mounted on the chuck and radially located by the pressing plates mounted on the clamping blocks, and the clamping blocks and the thin-wall flange as well as the pressing plates and the thin-wall flange are both in surface contact, so that the thin-wall flange can be located more precisely, and the turning accuracy is higher.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a clamp, in particular to a thin-wall flange precision vehicle outer circle clamp. Background technique [0002] Conventional thin-walled flanges have thin walls, insufficient rigidity, and are easy to deform. Using conventional fixtures, the machining accuracy cannot meet the requirements and the pass rate is low due to the uneven clamping force that causes the deformation of the parts. For the cylindrical turning of thin-walled flanges with high requirements, it is difficult to control the deformation with conventional fixtures, and it is also difficult to ensure the processing accuracy. [0003] Chinese Utility Model Patent (CN 204321649 U) discloses a multi-point auxiliary support and clamping device for machine tools. The bottom of the pile head base is provided with a "T"-shaped slider, and the two sides of the pile head base are provided with auxiliary support arms. A plu...
