Problems solved by technology

For internal combustion engine crankshaft and connecting rod journal technology, traditional processing equipment can no longer keep up with the pace of modern production in terms of cycle time and processing quality stability. For internal combustion engine crankshaft machining, the machine tool lacks rigidity, and ordinary cutterhead cutting is not suitable for machining large crankshafts, and the maintenance frequency of CNC lathes has increased significantly after three or four years of use

Abstract

The invention relates to a high-accuracy numerical control excircle milling machine and belongs to the technical field of machine tool operation. The high-accuracy numerical control excircle milling machine comprises a machine body and a machine tool. The machine body is in an inverted L shape. The machine tool is mounted on the machine body. The machine tool comprises a unit A, a screw type chip removing machine, a flat plate type chip removing machine and a unit B. The unit A is located at the outer end of the screw type chip removing machine; the unit B is located at the outer end of the flat plate type chip removing machine; the screw type chip removing machine and the flat plate type chip removing machine are perpendicular to each other and the inner end of the screw type chip removing machine and the inner end of the flat plate type chip removing machine are communicated; the screw type chip removing machine is higher than the flat plate type chip removing machine. The high-accuracy numerical control excircle milling machine is applied to crankshaft connecting rod journal machining and has the advantages of being low in cost, high in accuracy, good in machining stability and the like.

Description

technical field [0001] The invention relates to a high-precision numerically controlled cylindrical milling machine, which belongs to the technical field of machine tool operations. Background technique [0002] Internal combustion engine crankshaft processing is a machinery manufacturing industry that requires high automation, high precision, fast production cycle and good processing stability. In recent years, based on various considerations such as changes in the labor force structure and enterprise cost management, the reduction of production line operators and the integration of equipment processing procedures have become a trend. For internal combustion engine crankshaft and connecting rod journal technology, traditional processing equipment can no longer keep up with the pace of modern production in terms of cycle time and processing quality stability. For the machining of internal combustion engine crankshafts, machine tools lack rigidity. Ordinary cutterhead cuttin...
