Abstract

The invention discloses a clamping fixture for outer cylinder parts. The clamping fixture comprises a flexible clamping system and a transfer fixture, wherein the flexible clamping system is connectedwith a base plate; the left end of a base shaft penetrates through the base plate, and is connected with the flexible clamping system through a zero positioning pull nail; a tensioning ring sleeves the outer side of the right end of the base shaft through a thread; a conical pin glidingly sleeves the right end; the tensioning ring, the base shaft and the conical pin are connected through positioning pins; a slotting bushing sleeves the outer side of the right end of the conical pin; an outer conical surface is arranged on the conical pin; an inner hole of the slotting bushing is correspondingly set as a conical hole; the right end surface of the base shaft is a positioning surface; the positioning surface is perpendicular to the axis of the base shaft; and the tail end surfaces of the parts are contacted with the positioning surface of the base shaft for positioning. The clamping fixture needs no additional process boss, uses self characteristics of the parts for realizing positioningand clamping, realizes complete positioning, and solves the problems of axial rotation and movement in a traditional clamping mode.

Description

technical field [0001] The invention belongs to the technical field of clamping fixtures, and in particular relates to a clamping fixture for outer cylinder parts. Background technique [0002] At present, the outer cylinder parts use the chuck and the top to realize "one clamp and one top" on the turn-milling compound machine tool. However, there are still many problems in the clamping of outer cylinder parts. There are two typical problems: [0003] First, the parts need to be designed with a separate process boss, which increases the processing content of the parts and complicates the process; [0004] Second, there is always the problem of movement and rotation along the axial direction, and the manufacturing risk is high. Due to the unreliability of clamping, in actual processing, it is necessary to reduce the risk of part rotation by reducing cutting parameters and increasing position review. The efficiency is low, and the operator is stressed. [0005] Therefore, t...
