Double-spindle handstand turning and milling composite machining system

Abstract

The invention relates to a double-spindle handstand turning and milling composite machining system which comprises a turning spindle and a milling spindle. The tail of the turning spindle faces upwards and the head of the turning main shaft faces downwards in a handstand manner, and a workpieces is lifted and clamped to rotate. The tail portion of the milling spindle faces downwards and the head portion of the milling spindle faces upwards in a handstand manner, and a tool is clamped to rotate. The turning spindle is arranged above the milling spindle, and a workpiece is arranged between the two spindles and is machined with a hole opening facing downwards. The head portion of the turning spindle is fixedly provided with a hydraulic three-claw chuck, and the three-claw chuck goes from andback to an unloading station of a workpiece storing and transporting system. The turning spindle is driven by a feeding system for completing feeding movement of all linear coordinate axes. A power tool rest is fixedly installed below the turning spindle and does not do feeding movement. A chain type closed circulation workpiece storing and transporting system is used for bringing blanks to be machined into the workpiece unloading station in a machine tool and transporting machined finished pieces out of the unloading station. By means of the double-spindle handstand turning and milling composite machining system, the chip discharging and removing function of the a machine tool spindle is improved based on the basic principle and structure, a single machine tool or wire groups are not affected or little affected by accumulated chip, and therefore parts can be continuously and automatically machined with high performance for a long time.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a double-spindle inverted turning-milling compound processing system. Background technique [0002] In the traditional vertical lathe, the tail of the main shaft faces down and the head faces up to clamp the workpiece to rotate; in the traditional vertical boring and milling machine, the tail of the main shaft faces up and the head faces down to hold the tool to rotate. For these two types of machine tools with parallel spindles, the hole of the workpiece is processed upwards, and chip removal and cleaning are very difficult, and chip accumulation in the hole is serious. For blind hole parts, tool chip removal becomes more difficult, which affects the normal processing of the machine tool, and even breaks the tool waste. Accidents and other long-standing historical issues. Contents of the invention [0003] The technical problem to be solved by the present invention is:...
