Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of numerical control machine tool, especially to a double-spindle double-five-axis vertical-horizontal hybrid machining machine tool. BACKGROUND

[0002] The traditional five-axis linkage machining machine tool is installed in the direction of water or vertical relative to the workpiece, that is, only horizontal and vertical machining assemblies are installed each time, and the single spindle orientation type limits the movement direction of the cutter to some extent, so that only limited parts of the workpiece can be machined in single clamping. In the aerospace, automobile and die manufacturing industries, there are a large number of large-size complex structural parts, such as integral bladed disks and large engine casings. Such parts have the characteristics of complex structure and high part forming precision, and it is difficult to complete the machining of all features on a single vertical five-axis machining machine tool or a single horizontal five-axis machining machine tool. Therefore, all machining processes are often completed in succession on multiple vertical and horizontal five-axis machining machine tools. Multiple machining processes of multiple devices involve multiple processes, and the time consumed by workpiece loading and unloading and spindle tool changing in each process accounts for a large proportion of the entire machining cycle of the part, which greatly restricts the manufacturing efficiency of the part. Moreover, when the machining process involves re-clamping, it is difficult to ensure the consistency of the clamping position, which will inevitably lead to positioning cumulative error and reduce the machining precision of the workpiece. Therefore, how to provide a high-precision and high-efficiency compound machining center device to realize high-quality and high-efficiency manufacturing of high-precision complex parts is a problem that needs to be solved by those skilled in the art.
