Problems solved by technology

However, there is a problem in Patent Document 1 that when the workpiece is loaded into the machine tool, the centering process is performed after the workpiece is temporarily placed on the temporary support of each chuck device.
When inserting the tip next, the tip hits the two ends of the workpiece and cannot be inserted into the tip hole. There are problems such as abnormal stop of the machine tool.
In Patent Document 2, there is also an alignment problem, specifically: the first temporary support and the second temporary support are fixed at the relative position to the tip, and when the temporary support surfaces at both ends of the workpiece have errors, the When the central axis and the axis of the top are at the same height, the support of the first temporary support surface and the second temporary support surface will cause the central axis of the workpiece to be different from the top, and the machine tool will also be abnormal at this time; and the first temporary support surface and the second temporary support surface have high precision requirements, and the cost of the machine tool is high; in addition, it is necessary to set the first temporary support surface and the second temporary support surface of the workpiece as circumferential surfaces, and the first temporary support surface and the second temporary support surface of the workpiece The accuracy requirements of the second temporary support surface are higher
[0003] And there is no good technical means in the prior art that can accurately solve the above technical problems

Abstract

The invention belongs to the field of machining of shaft-shaped / bar-shaped workpieces, in particular to a machining device for shaft-shaped workpieces. The device comprises a base, a first workbench and a second workbench, and further comprises a temporary workpiece supporting table. The temporary workpiece supporting table is installed on the base in the mode of being capable of moving in the longitudinal direction and the height direction of the base, and is located between the first workbench and the second workbench. The purpose that shaft-shaped / bar-shaped workblanks are aligned to a centre of a machine tool can be achieved through the machining device.

Description

technical field [0001] The invention belongs to the field of processing shaft-shaped / rod-shaped workpieces, in particular to a processing device for shaft-shaped workpieces. Background technique [0002] At present, processing machine tools for the purpose of efficiently processing forged or cast shaft / rod workpieces (such as crankshaft blanks, etc.) are generally processed by positioning the center. For example, Patent Document 1: Japanese Patent Application Laid-Open No. 2007-245282, and Patent Document 2: Chinese Patent CN104271292A "Method for Manufacturing Rod-shaped Parts". Among them, the processes performed in Patent Document 1 when machining a workpiece are: a centering process, a temporary support portion forming process, and a final finishing process. However, there is a problem in Patent Document 1 that, when a workpiece is loaded into a machine tool, the centering process is performed after the workpiece is temporarily placed on the temporary support of each ch...
