Ultrahigh-precision numerically-controlled non-circular curved surface composite grinder

Abstract

An ultrahigh-precision numerically-controlled non-circular curved surface composite grinder comprises a grinder bed and an upright post capable of moving forwards and backwards; a workbench is located at the front end of the grinder bed; a headstock, a tailstock and a measuring device are mounted on the workbench; a horizontal-axis grinding wheel disc and a vertical-axis grinding wheel disc are mounted on the movable upright post; a composite grinding function is realized through accurate control of four servo axes, namely an axis X, an axis Y, an axis Z and an axis C; and a workpiece can be subjected to excircle grinding, plane surface grinding, groove grinding, prismatic polyhedron grinding and end surface grinding through one-time clamping, and can also be subjected to non-circular curved surface grinding through linkage differential complement of the axis C and the axis X. The ultrahigh-precision numerically-controlled non-circular curved surface composite grinder has the characteristics of high machining precision, wide application range, high production efficiency and the like.

Description

technical field [0001] The invention relates to a grinding machine in mechanical processing equipment, in particular to an ultra-high-precision numerical control non-circular surface compound grinding machine, which belongs to the field of mechanical processing machine tools. Background technique [0002] Grinding machine in mechanical processing equipment is a conventional precision machining machine tool, including internal cylindrical grinding machine, external cylindrical grinding machine, surface grinding machine, tool grinding machine, etc., according to the layout of the main shaft of the grinding head, it is divided into two types: vertical axis and horizontal axis. Conventional grinding machines generally only have A grinding head with a single function, the grinding machine for grinding the outer circle cannot grind the plane, and the grinding machine for grinding the plane cannot grind the outer circle. Recently, some multi-grinding head compound grinding machines...

[0002] Grinding machine in mechanical processing equipment is a conventional precision machining machine tool, including internal cylindrical grinding machine, external cylindrical grinding machine, surface grinding machine, tool grinding machine, etc., according to the layout of the main shaft of the grinding head, it is divided into two types: vertical axis and horizontal axis. Conventional grinding machines generally only have One grinding head with a single function, the grinding machine for grinding the outer circle cannot grind the plane, and the grinding machine for grinding the plane cannot grind the outer circle

Recently, some multi-grinding head compound grinding machines have also appeared, such as CN103817582A has introduced a kind of numerical control internal and external circle and end face compound grinding machine, it is provided with three horizontal grinding heads, mainly for the inner hole, end face, outer surface of various gears in the automobile industry. For the finishing of rotating surfaces such as circles, CN103302558A introduces a CNC compound grinding machine and its grinding method, which is also aimed at the finishing grinding of the inner circle, outer circle and end face of large bearings or gears. These are special grinding machines for specific parts. For some shaft parts, such as the oil port side of the input shaft of the automobile power steering gear, polyhedral shaft, outer circle, axial groove, end face, etc., how to achieve high-precision grinding in one clamping, and non-circular surfaces such as camshafts High-precision grinding, currently the existing grinding machine and technology can not be realized
