Abstract

The invention discloses a thin-walled cone workpiece machining process and a clamp device thereof. A cone workpiece comprises a big end face and a small end face. According to the process, the clamp device is arranged for conducting the four steps of turning of a technological top, turning of a spinning technological flange edge, turning of the small end face and turning of the big end face. The clamp device comprises a first clamp mechanism and a second clamp mechanism. The first clamp mechanism comprises a conical sleeve and a conical sleeve fixing device. The conical sleeve is matched and fixed with the conical sleeve fixing device through a bolt. The second clamp mechanism comprises a mandrel, a locknut, an expansion plate, a limiting plate and a core expansion nut. The locknut and thecore expansion nut are arranged on the mandrel. The mandrel penetrates through the interior of the cone workpiece, one end of the mandrel is clamped through a clamping jaw, and the other end of the mandrel abuts against a centre. The cone workpiece is fixed axially and radially, the radial stiffness and strength and the axial stiffness and strength of the cone workpiece are greatly improved, theproblems that thin-walled cone workpieces are difficult to clamp and liable to be deformed by clamping during machining are effectively solved, and the dismounting and mounting efficiency during assembling is improved.

Description

Technical field [0001] The invention relates to the field of mechanical processing, in particular to a processing technology of a thin-walled cone workpiece and a fixture device thereof. Background technique [0002] The main technical requirements for cone workpieces are the perpendicularity between the two end faces and the axis and the mutual parallelism between the two end faces. The thin-walled cone workpiece has a very thin wall and weak radial rigidity. It is easily deformed due to factors such as cutting force, cutting heat and clamping force during the machining process, which makes it difficult to guarantee the technical requirements, while the general processing methods cannot For this type of workpiece clamping and processing, the current processing technology and process of thin-walled cone workpieces using ordinary lathes, thin-walled workpieces have technical problems such as easy deformation, part dimensional accuracy, position accuracy and surface roughness are n...
