Abstract

The invention relates to a clamping method and a clamp for thin-wall cylindrical part turning as well as a processing device. The clamp comprises a first supporting shaft and a second supporting shaft, wherein one end of the first supporting shaft and one end of the second supporting shaft are connected to a tightening mechanism; the tightening mechanism is used for applying inner supporting forceto the two ends of a thin-wall cylindrical part; a limiting structure is arranged on the tightening mechanism; and the limiting structure is used for limiting axial movement of the thin-wall cylindrical part. The clamping method and the clamp disclosed by the invention avoid the problem that a workpiece has clamping deformation and chattering, and improve processing precision.

Description

technical field [0001] The invention relates to the technical field of turning processing, in particular to a clamping method, a fixture and a processing device for turning a thin-walled cylindrical part. Background technique [0002] The existing processing methods and tooling for thin-walled cylindrical parts mainly include: first, the most common method is to add an elastic sleeve to the outer circle of the workpiece for radial clamping or clamping with a three-jaw chuck. This technology is easy to clamp the workpiece Deformation, reduced precision, and low production efficiency; the second is the one-piece shaft fixation, allowing the workpiece to be set on the shaft and fixed at both ends, and the middle is filled with rubber, paraffin and other media. Due to the heat generated by the processing engineering, the media will melt and the filling will be uneven. , so it is easy to cause the workpiece to flutter. The integrated solid shaft type makes the machine tool spind...
