Reconfigurable gear compound machining center

Abstract

The invention discloses a reconfigurable gear combined machining center. The reconfigurable gear combined machining center comprises a tool main movement SP1-axis system, a diamond roller dressing SP2-axis system, a radial feed X-axis system, an axial feed Z-axis system, a tangent feed Y-axis system, a spiral angular indexing A-axis system, a working table indexing C-axis system, a rear stand column auxiliary positioning Z2-axis system, an automatic tool switching system and an online measurement system. A machine tool has the high-precision composite machining functions including the forming and gear milling functions, the contour evolution gear hobbing functions, the shaping and gear grinding functions and the five-axis linkage milling function, the outer circles and the end faces of shaft class parts and disc class parts can be simultaneously milled or ground, the requirement for the rough and fine machining of small and medium size externally-toothed cylindrical straight bevel gears, spiral gears, various special-shaped tooth surfaces and free-form surfaces can be met, multiple purposes are achieved through one machine, the machining efficiency of a single product is improved by 30% or higher, the device input is saved by 50%, and the floor area of plants is reduced by 60%.

Description

technical field [0001] The invention relates to a gear processing machine tool, more specifically to a reconfigurable gear compound machining center, which belongs to the field of advanced manufacturing technology. Background technique [0002] Gears are the basic parts of the machinery industry. In recent years, the downstream industries of the gear industry have developed vigorously, including automobiles, construction machinery, wind power nuclear power thermal power energy devices, rail transit, robots, aerospace and weaponry, ships and marine engineering equipment, etc.; In the seven years from 2007 to 2013, the sales of the gear industry have maintained a substantial increase. As of 2013, the annual output value has exceeded 200 billion yuan. There are obvious gaps with developed countries in terms of process parameters and gear testing equipment. The overall quality stability of the product is poor, the production efficiency is low, and the energy consumption is high....

AI Technical Summary

Problems solved by technology

The substantial increase in the absolute number of gears, coupled with the continuous increase in the ratio of hardened gears, has led to an increase in the demand for grinding gears driven by double factors, and the domestic ratio of hardened gears is only 7%. , about the general ratio of foreign hard tooth surfaces, so this growth will continue for a long time
