Description

[0002] When the cylinder barrel part is subjected to internal hole push boring processing on a boring machine, its positioning and clamping rely on the inner conical surfaces of the headstock and the tailstock chuck, and the positioning and clamping of the cylinder barrel are achieved by contacting and pressing against the pre-turned chamfers at both ends of the cylinder barrel. During the actual processing, affected by the machining errors such as roundness and coaxiality of the chamfer machining of the cylinder barrel, there will be a situation where the central axes of some cylinder barrels do not coincide with the central axes of the headstock and the tailstock during clamping. This will result in the non-tight contact between the inner conical surfaces of the headstock and the tailstock and the chamfer surfaces of the cylinder barrel, so that the workpiece will slide relatively due to the unstable positioning and clamping fit at the headstock or tailstock end during processing, and finally the workpiece cannot continue to be processed or defects will appear in the inner hole.
