Problems solved by technology

[0010] In order to effectively solve the problem that the existing helical milling device is large in size and mass, resulting in excessive load on the joint arm robot and the end of the machine tool, and at the same time, the adjustment accuracy of the rotation angle of the eccentric adjustment axis is low, and the rotation consistency between the eccentric adjustment axis and the revolution axis is poor. The problem of accumulation of errors caused by the nesting of layer standard bearings, the invention provides a device and method for making helical milling holes

Abstract

The invention belongs to the technical field of automatic hole production, and concretely relates to a helical milling device and a helical milling method. The helical milling device comprises an autorotation shaft, an eccentric adjusting shaft, a revolution shaft, a revolution belt pulley, an adjusting belt pulley and a control system, and further comprises an adjusting shaft detection grating ruler and a revolution shaft detection grating ruler, and full-closed loop detection is performed on the rotation angle of the eccentric adjusting shaft and the synchronization of the revolution shaft and the eccentric shaft. The revolution shaft, the eccentric adjusting shaft and the autorotation shaft of the device are provided with raceways, rolling elements are clamped in the raceways, and the self race ways and the rolling elements are adopted to substitute standard bearings, so problems of low rotating angle adjusting precision of existing helical milling devices and poor rotating consistence of the eccentric adjusting shaft and the autorotation shaft, and problems of overlarge use load of a hinged arm robot and a machine tool end and error accumulation caused by nesting of multilayerstandard bearings, caused by large size and large mass of the device are solved.

Description

technical field [0001] The invention relates to the technical field of automatic hole making, in particular to a helical hole milling device and method. Background technique [0002] One generation of materials and one generation of equipment, with the increasing use of high-end materials such as composite materials and titanium alloys in the fields of aviation, aerospace, transportation and other high-end equipment manufacturing, composite materials, difficult-to-process materials and their composites will follow. High-efficiency and high-precision machining requirements for high-precision assembly holes in high-end equipment manufacturing applications. As an emerging hole processing technology, helical milling holes are replacing traditional drilling processes to meet the high-efficiency and high-precision holes in high-end equipment. processing needs. [0003] The focus of the application of the helical milling process is to develop a special helical milling device to re...
