A processing device for rod-shaped workpieces

Abstract

The invention belongs to the field of shaft-like / rod-like workpiece processing and particularly relates to a processing device for a rod-like workpiece. The processing device comprises a base, a first workbench and a second workbench; the first workbench is mounted at one end of the base, can freely move relative to the base along the length direction of the base and can freely move along the height direction of the base; the second workbench is mounted at the other end of the base and can freely move relative to the base along the length direction of the base and can freely move along the height direction of the base; the first workbench is arranged in a way of being opposite to the second workbench; the first workbench is provided with a first centre along the length direction of the base; the second workbench is provided with a second centre along the length direction of the base; and when being located on the same height, the first centre and the second centre are located on the same axis. The problem that a centre of a rod-like rough workpiece is not aligned with a centre of a processing machine tool can be solved.

Description

technical field [0001] The invention belongs to the field of processing shaft-shaped / rod-shaped workpieces, in particular to a processing device for rod-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 chuc...

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
