Elastic supporting tool for machining thin-wall inner conical surface part

Abstract

The utility model discloses an elastic support tool for processing a thin-wall inner conical surface part, which comprises a tool body and a fastener which are detachably connected, one end of the tool body is a fixed seat, the other end of the tool body is an expansion seat, a plurality of expansion grooves are uniformly distributed on the outer side of the expansion seat, an annular step is arranged on the periphery of the fixed seat, and the annular step is arranged on the outer side of the expansion seat. The step is used for limiting displacement of the thin-wall inner conical surface part on the outer side of the expansion seat; when the thin-wall inner conical surface part is nested on the outer side of the expansion seat, the fastener penetrates through the end of the thin-wall inner conical surface part and extends into the inner side of the expansion seat, the expansion groove is driven to contract or expand by adjusting the connecting position of the fastener on the inner side of the expansion seat, and the outer wall of the expansion seat is attached to the inner conical surface of the thin-wall inner conical surface part. The fixture has the advantages of compact structure, convenience in disassembly and assembly, reliability in connection, convenience in clamping and positioning and the like, provides stable support for a thin-walled part with a conical surface in the inner shape, and improves the quality stability of machining of an outer shape circle at the conical surface.
