The drilling machining station is equipped with a second spindle 20. The second spindle 20 can change its angle through the first rotary platform 21 to realize the drilling and denting machining of valve holes, as well as the chamfering machining of bolt holes.

[0017] The first turret 4 is located on the left side of the turning spindle 28, and the third turret 30 is located on the inner side of the turning spindle 28. The first spindle 10 is located on the upper left of the third turret 30, and the second turret 14 is located on the upper right. The first tool magazine 6 is located on the far left of the bed 2. The second station on the right is the drilling station. The second spindle 20 is located above the second fixture 24, and the second tool magazine 25 is located on the far right of the bed 2.

[0018] The first servo X-axis 3, the first servo Z-axis 7, and the first turret 4 form the first tool station. The first servo X-axis 3 and the first servo Z-axis 7 drive the first turret 4 to move along the X-axis and Z-axis, and complete the rough turning process of the aluminum wheel outer rim through the outer rim rough turning tool 8. The fourth servo Z-axis 31, the first servo Y-axis 29, and the third turret 30 form the second tool station. The fourth servo Z-axis 31 and the first servo Y-axis 29 drive the third turret 30 to move along the Y-axis and Z-axis, and complete the finish turning process of the aluminum wheel outer rim through the outer rim finish turning tool 32.

[0019] The second servo Z-axis 12 and the second servo X-axis 9 form a two-axis linkage servo unit, driving the first moving platform 13 to move along the X-axis and Z-axis. The first spindle 10 is fixed on the first moving platform 13 and is connected to the bolt hole drill bit 11. A first tool magazine 6 is set on the left side, which stores bolt hole drill bits 11 for different products, and can complete the bolt hole processing of aluminum wheels.

It can complete the valve hole processing, valve hole grooving, bolt hole chamfering, and bolt hole grooving processes of aluminum wheels. Specifically, the second motor controls the valve hole drill bit 22 to perform processing through the second spindle 20. The third rotary motor can control the second spindle 20 to tilt at an angle, thereby completing the valve hole processing, valve hole grooving, bolt hole grooving, and bolt hole chamfering processes. The fourth rotary motor controls the second tool magazine 25 to switch between relevant valve hole drill bits, valve hole grooving drill bits, and bolt hole chamfering drill bits.

[0022] The first tool changing robot 5 and the second tool changing robot 26 are respectively located below the first tool magazine 6 and the second tool magazine 25, and are used to perform tool changing operations.

[0023] The working process of a dual-station milling and turning machine tool for aluminum wheels is as follows: First, the aluminum alloy wheel 23 is clamped on the first fixture 27. The turning spindle 28 rotates, driving the aluminum alloy wheel 23 to the turning speed. The wheel is then machined using the roughing tool 8 of the first row of cutters for the outer rim, while simultaneously the second turret 14 uses the riser cutting tool 15 for machining. After the riser machining is completed, the second turret 14 changes tools and uses the front roughing tool 16 for machining. At this point, the first row of cutters has completed part of the rough machining of the outer rim. The second row of cutters uses the outer rim finishing tool 32 to finish the rough-machined outer rim portion. With the roughing and finishing of the outer rim and the front roughing and finishing machining completed, the turning of the wheel is finished. Figure 2 As shown.

[0024] At this point, the first spindle 10 rotates, sequentially machining the bolt holes of the wheel. After the bolt holes are machined, the machining at the first station is complete, and the wheel is transferred to the second fixture 24 at the second station via the grippers. The second spindle 20 rotates and is positioned at a suitable angle via the first rotating platform 21 to machine the valve holes, valve hole recesses, bolt hole chamfers, and bolt hole recesses. After machining is completed, the machining at the second station is finished, and the aluminum wheel is transferred off the production line to subsequent processes, such as... Figure 3 As shown.
