Lubricating system for universal double-swing head of large-scale numerical control machining center

Abstract

The invention relates to a lubricating system for a universal double-swing head of a large-scale numerical control machining center. The lubricating system comprises an external gas source, an internal oil tank, an oil gas generating device and an oil gas conveying device, wherein the oil gas generating device consists of a compressed air nozzle piece and an oil gas mixing block; the compressed air nozzle piece is a rotation body, and a hollow inner cavity comprises an inlet pipe, a throat pipe and a conical nozzle cavity sequentially from a compressed air inlet to a compressed air outlet; a hollow inner cavity of the oil gas mixing block comprises an inlet cavity, a vacuum cavity, a diffusion cavity and an outlet cavity sequentially from the compressed air inlet to the compressed air outlet; the external gas source is communicated with the inlet pipe of the compressed air nozzle piece by a compressed air pipeline; the oil gas conveying device comprises an oil gas distributor, an output pipeline and a condensation nozzle; lubricating points of the universal double-swing head are formed at an outlet of the condensation nozzle; the condensation nozzle is connected with the output pipeline; the output pipeline is connected with the oil gas distributor; the oil gas distributor is communicated with the outlet cavity of the oil gas mixing block. The lubricating system is good in lubricating and cooling effects, low in requirement on space sizes and reasonable in cost.

Problems solved by technology

[0007] In order to overcome the traditional thin oil pressure lubrication and high-speed grease lubrication in large-scale CNC machining centers, the lubrication and cooling effect is poor, and the lubrication system requires a large space size, which affects the performance of the CNC universal double-oscillating head. Insufficient overall processing speed and precision, the present invention proposes a lubricating system for a large-scale CNC machining center with a universal double-oscillating head that has good lubricating and cooling effects, low requirements on space size, and reasonable cost
