Specific details of the apparatus and the operation of the utility model are set forth in the following description with reference to the figures.

A combined machine tool for machining a steering knuckle is composed of a portal frame 1, a Y-axis driving motor 2, a Y-axis moving slide block 3, an X-axis driving motor 4, an X-axis moving slide block 5, a first Z-axis driving motor 6, a second Z-axis driving motor 7, a first main shaft 8, a second main shaft 9, a first swinging main shaft 10, a second swinging main shaft 11, a front protective door 12, a rear protective door 13, an upper protective door 14, an A-axis turntable driving motor 15, an A-axis turning plate 16, a first C-axis driving motor 17, a second C-axis driving motor 18, a third C-axis driving motor 19, a fourth C-axis driving motor 20, a first C-axis 21, a second C-axis 22, a third C-axis 23, a fourth C-axis 24 and a workbench support 25.

The two portal frames 1 are symmetrically arranged left and right, wherein a Y-axis driving motor 2 is arranged on the left portal frame, the output end of the Y-axis driving motor 2 is connected with a Y-axis moving slide block 3, and the Y-axis moving slide block 3 can be driven to vertically move through the Y-axis driving motor 2 to form a Y-axis of the machine tool; the X-axis driving motor 4 is fixed on the Y-axis moving slide block 3, the output end of the X-axis driving motor 4 is connected with the X-axis moving slide block 5, and the X-axis moving slide block 5 can be driven to horizontally move through the X-axis driving motor 4 to form an X axis of the machine tool; the first Z-axis driving motor 6 and the second Z-axis driving motor 7 are fixed on the X-axis moving sliding block 5, the output end of the first Z-axis driving motor 6 is connected with the first main shaft 8, the output end of the second Z-axis driving motor 7 is connected with the second main shaft 9, and the first main shaft 8 and the second main shaft 9 can be driven to move in a feeding mode through the first Z-axis driving motor 6 and the second Z-axis driving motor 7, so that a left double Z-axis of the machine tool is formed. The right portal frame structure is the same as the left side, and X-axis and Y-axis kinematic pairs are the same, and the difference is that the right double Z-axis is different, and the right double Z-axis comprises a first swing main shaft 10 and a second swing main shaft 11. The term "oscillating spindle" here means that the spindle can rotate about the X axis, and an oscillating movement of the spindle about the X axis is achieved by the oscillating spindle.

The workbench support 25 is a fixed base, a fourth shaft, namely an A shaft and a turning plate thereof, can drive the A shaft turning plate to rotate 360 degrees through the A shaft turntable driving motor 15, four C shafts are arranged on the A shaft turning plate 16 and are respectively a first C shaft 21, a second C shaft 22, a third C shaft 23 and a fourth C shaft 24, and the four C shafts are respectively driven by a first C shaft driving motor 17, a second C shaft driving motor 18, a third C shaft driving motor 19 and a fourth C shaft driving motor 20.
