Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of processing equipment, in particular to a turning and milling compound processing center. Background Art
[0002] A turning-milling composite machining center is a device that combines turning and milling processing methods on a single machine tool. It can complete the processing of multiple surfaces in a single clamping, so that the workpiece meets the use requirements in terms of shape accuracy, position accuracy and integrity of the processed surface. It has multiple motion axes, the most common of which are X, Y, Z axes and C axis for rotation. The coordinated movement of these axes can realize complex processing actions and meet the processing requirements of different shapes and angles.
[0003] The turning-milling composite machining center uses its milling function, combined with high-precision control devices, to accurately process the contour curve of the cam and turn the camshaft journal, ensuring the overall accuracy of the camshaft and helping to optimize the engine's intake and exhaust efficiency.
[0004] The turning-milling composite machining center can turn the outer circle of the drive shaft to ensure the diameter accuracy and cylindricity of the shaft, and mill the keyway and spline connection parts at the same time. However, for complex accessories, multiple processing steps are currently required. If it is not possible to use multiple mechanisms for simultaneous processing, the turning, milling and drilling operations must be completed in sequence. For a mold accessory that requires turning multiple surfaces and milling complex cavities, under the traditional single-process processing method, the transition between each process requires waiting for the previous process to be completed, tool replacement and repositioning operations, resulting in a significant increase in the entire processing time, thereby extending the production cycle.
