[0002] A CNC machining center is a high-efficiency automated machine tool composed of mechanical equipment and a CNC system, suitable for machining complex parts. However, due to their large footprint and high cost, CNC machining centers are not suitable for single-type machining, such as simple turning or simple milling. Currently, turning is still performed on lathes and milling on milling machines, requiring separate operations on two different machine tools.

The chuck is mounted on the upper end of the turning electric spindle. A rotary cylinder for driving the turning electric spindle is provided at the lower end of the turning electric spindle.

[0006] The milling assembly includes a milling electric spindle and a swivel head base, with the milling electric spindle rotatably mounted on the swivel head base. Compared to existing technologies, this solution achieves both turning and milling of parts by vertically arranging the turning and milling assemblies opposite each other on the machine bed, and allowing the milling assembly to be displaced relative to the turning assembly. This is achieved by integrating the turning and milling assemblies onto a single machine bed, satisfying the needs of parts requiring two different machining processes. The overall structure of the composite machine tool is compact, and it occupies a small area.

[0007] In some preferred embodiments, a column is provided on the rear side of the bed, and the displacement mechanism is mounted on the column.

[0009] To realize the X-axis displacement mechanism, in some preferred embodiments, the X-axis displacement mechanism includes a first linear guide rail and a saddle mounted on a column. The first linear guide rail is arranged along the X-axis direction. A first slider is provided on the saddle and is slidably mounted on the first linear guide rail. A first screw is rotatably mounted on the column. The first screw is arranged parallel to the first linear guide rail and is threadedly connected to the saddle.

[0011] In order to realize the first drive mechanism and the second drive mechanism, in some preferred embodiments, both the first drive mechanism and the second drive mechanism are servo motors.

[0012] To facilitate tool changing for the milling assembly and improve its automation, in some preferred embodiments, a tool magazine assembly is provided on one side of the column, which is used to change tools for the milling assembly.

[0013] In order to facilitate the removal of waste chips after turning and milling without affecting the turning and milling, in some preferred embodiments, the chip removal groove includes a first groove and a second groove provided on the upper surface of the machine bed, and the turning assembly is located between the groove opening of the first groove and the groove opening of the second groove.

[0014] In some preferred embodiments, both the first groove and the second groove extend downward from the upper surface of the bed to one side of the bed.

[0015] In some preferred embodiments, the openings of the first groove and the second groove both have outward-facing flared openings.

[0016] The beneficial effects of this utility model are as follows: When using the vertical turning and milling composite machine tool of this utility model, turning and milling components are arranged opposite each other in the vertical direction on the machine bed, and the milling component can be displaced relative to the turning component, so as to realize turning and milling of parts. They are integrated on one machine bed to meet the needs of parts for two processing operations. The overall structure of the composite machine tool is compact and occupies a small area. It avoids the problem that the existing method still requires turning to be done on a lathe and milling to be done on a milling machine. This method requires turning and milling to be done on two separate machine tools, which increases the processing time of parts and also results in a large footprint and high operating costs.
