Cycloid rotational indexing-based novel vertical milling machine

Abstract

The invention relates to vertical milling machines and belongs to the field of machining. A cycloid rotational indexing-based novel vertical milling machine is characterized by comprising a machine body mechanism, a milling head mechanism and a worktable mechanism. The cycloid rotational indexing-based novel vertical milling machine comprises two working modes: rotational indexing machining and milling by an eccentric milling cutter. In the rotational indexing machining mode, the milling cutter in compound movements of rotation and revolution is matched with two-dimensional translation of a to-be-machined workpiece and a vertical movement of the milling head mechanism to form a special movement track of the milling cutter relative to the to-be-machined workpiece so as to machine a special part in a complex shape. The milling mode by the eccentric milling cutter is as follows: the milling cutter is fixed in an expected position relative to the rotary center of a spindle box to form the eccentric milling cutter, and the rotation movement of the eccentric milling cutter is combined with two-dimensional translation of the to-be-machined workpiece and a vertical movement of the milling head mechanism. The cycloid rotational indexing-based novel vertical milling machine provided by the invention retains the functions of a conventional milling machine and increases a mode of efficiently machining the part in the special shape by cycloid rotational indexing. The two modes can be freely switched, so that the cycloid rotational indexing-based novel vertical milling machine is of certain universality.

Description

technical field [0001] The invention relates to a vertical milling machine, in particular to a novel vertical milling machine with two working modes of rotary division processing and eccentric milling cutter milling processing. Background technique [0002] High-efficiency NC machining is an inevitable development trend in the field of NC machining, and cycloid rotary indexing (spinning) machining technology is one of the key technologies for high-efficiency NC machining. Based on the principle of cycloid, the multi-process and multi-process intermittent processing in traditional processing is changed into continuous processing, which realizes efficient and continuous milling processing, and can be applied to the cycloid pin wheel processing of robot joint RV reducer.
