Description

Technical Field

[0001] The utility model relates to the field of machine tools, in particular to an auxiliary chip removal fixture for a compound machine tool. Background Art

[0002] A compound machine tool is a CNC machine tool that integrates multiple processing technologies. It can complete multiple processing operations on the same machining center, such as milling, turning, drilling, etc., which improves the processing flexibility and comprehensive utilization rate of the machine tool.

[0003] When punching a plate product using a machine tool, a sleeve cutting tool is usually used for the punching process, that is, a driving motor drives the sleeve cutting tool to rotate so that the sleeve cutting tool cuts a circular hole on the plate product. However, when the sleeve cutting tool cuts a circular hole in the plate, circular waste generated by cutting the hole on the plate will be stuck in the sleeve cutting tool. When taking out the waste inside the sleeve cutting tool, the waste inside the sleeve cutting tool is usually taken out manually using a rod-shaped object. However, this will reduce the working efficiency of the machine tool and is not convenient for the machine tool to drive the sleeve cutting tool to rise and reset, so as to squeeze out the waste inside the sleeve cutting tool.
