Numerical-control combined gear milling and hobbing machine for machining large-modulus gear and application thereof

Abstract

The invention relates to a numerical-control combined gear milling and hobbing machine for machining a large-modulus gear and application thereof. The machine comprises a numerical control computer and is characterized in that a disc milling cutter and a hobbing cutter are fixedly arranged on a cutter bar, and a cutter bar gasket group is arranged between the hobbing cutter and the disc milling cutter; one face of an angular sliding plate is abutted with a cutter holder through a Y-shaped guide track and a guide groove, the other face of the angular sliding plate is supported on a vertical sliding plate through an A-direction bearing and a bearing, and the other face of the vertical sliding plate is abutted with an upright column through a Z-direction guide track and a guide groove; the upright column is abutted with a bed body through a guide track which is arranged horizontally in an X direction and a guide groove; a gear blank workbench is supported on a bottom surface through a C-direction shaft and a bearing which are engaged with each other; and clamps are arranged on the gear blank workbench. Under the control of the numerical control computer, the machine can perform the milling operation and hobbing operation on a gear with the modulus more than or equal to 15 mm in one step, so as to greatly increase the work efficiency.

Description

technical field [0001] The present invention relates to a numerically controlled gear hobbing machine and its application, in particular to a composite numerically controlled gear hobbing machine which has both slot milling and hobbing capabilities and is specially used for processing large modulus gears, and the application of the numerically controlled composite milling gear hobbing machine to process large Modular gear method. Background technique [0002] In recent years, wind power, shipbuilding, cement, metallurgy and other industries have developed rapidly, and the demand for mechanical transmission equipment has gradually increased. As a key component of mechanical transmission equipment, the market for gears has also increased accordingly. [0003] There are many ways to process gears, including gear hobbing, gear shaping, gear milling, gear shaving, gear grinding, etc. Among them, large modulus gears are usually processed by gear hobbing and gear milling.
