[0002] In the wheel manufacturing industry, as die-casting efficiency increases year by year, machining has gradually become a narrow bottleneck in the overall production line balance. There is an urgent need for new technologies to break away from existing processing methods. This patent breaks down and reorganizes the second and third machining steps of wheel machining, and based on the requirements of milling and turning composite machining processes, develops a new type of single-station machining tool that integrates the two and three machining steps. This improves the machine tool's integration, significantly increasing production efficiency while reducing machine tool footprint and production costs. Summary of the Invention

[0003] In view of this, the present invention aims to propose a single-station machining tool for aluminum wheels that integrates the second-stage turning and the third-stage drilling processes, reducing the number of machining tools from the existing three to two, thereby reducing the equipment footprint.

[0015] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0016] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] The following is for reference. Figures 1 to 2 The embodiments of the present invention are described in conjunction with the two- and three-stage integrated single-station machining tool for aluminum wheels.

[0018] A single-station machining center for aluminum wheels, comprising a chip conveyor 1, a bed 2, a valve hole drill bit to be replaced 3, a first disc-type tool magazine 4, a first servo X-axis 5, a first servo Z-axis 6, a first moving platform 7, a servo B-axis 8, a valve hole spindle 9, a servo angle head 10, a valve hole drill bit 11, a second servo Z-axis 12, a second moving platform 13, a bolt hole spindle 14, a bolt hole drill bit 15, a second disc-type tool magazine 16, a bolt hole drill bit to be replaced 17, a third servo Z-axis 18, an outer wheel rim turning tool 19, a third moving platform 20, a second servo X-axis 21, an aluminum wheel to be processed 22, a wheel fixture 23, and a machine tool turning spindle 24. Aluminum chips can be discharged during machine tool processing via chip conveyor 1; bolt holes can be machined via bolt hole drill bit 15; valve holes can be machined via valve hole drill bit 11; drill bits can be replaced via first disc tool magazine 4 and second disc tool magazine 16; and outer rims can be machined via outer rim turning tool 19.

[0019] The main workstation of the equipment is a milling and turning composite machining station. The workpiece is clamped in a single station, eliminating the need for secondary clamping and eliminating the positioning errors of the second-stage turning and third-stage drilling in traditional machining. Multiple machining axes are set up, and by optimizing the process layout, parallel machining of machining processes can be achieved, which greatly improves machining efficiency. The traditional two processes are combined into one process, saving floor space and improving the layout of the workshop.

[0020] The equipment is equipped with a turning spindle 24 at the center, which can drive the wheel clamp 23 to rotate and simultaneously drive the aluminum wheel 22 to be processed to rotate to a predetermined speed. A tool-cutting position is set on the right side of the worktable. The Y direction of this position is aligned with the centerline of the wheel to be processed. It consists of a third servo Z-axis 18, an outer wheel rim turning tool 19, a third moving platform 20, and a second servo X-axis 21. The outer wheel rim turning tool 19 is fixed on the third moving platform. The third moving platform 20 is driven by the third servo Z-axis 18 and the second servo X-axis 21 to complete the feed of the outer wheel rim turning tool 19, thereby realizing the turning of the wheel 22 to be processed.

[0021] A drilling station is set at the center of the equipment, which is the same station as the turning station.

[0022] The first servo X-axis 5, the second servo Z-axis 12, the second moving platform 13, the bolt hole spindle 14, and the bolt hole drilling bit 15 together form the bolt hole machining station. The first servo X-axis 5 and the second servo Z-axis 12 jointly drive the second moving platform 13 to move above the bolt hole to be machined. The bolt hole spindle 14 drives the bolt hole drilling bit 15 to reach the predetermined speed. With the indexing function of the turning spindle 24, the bolt hole is machined.

[0023] The first servo X-axis 5, the first servo Z-axis 6, the first moving platform 7, the servo B-axis 8, the valve bore spindle 9, the servo angle head 10, and the valve bore drill bit 11 together constitute the valve bore machining station. The valve bore drill bit 11 is fixed on the servo angle head 10, which is connected to the valve bore spindle 9 to provide drilling power. The servo B-axis 8 is fixed on the first moving platform 7, and its output end is connected to the valve bore spindle 9. The first servo X-axis 5 and the first servo Z-axis 6 jointly drive the first moving platform 7, causing the valve bore drill bit 11 to reach a preset position. The servo angle head 10 and the servo B-axis 8 then position the valve bore drill bit 11 at a suitable angle to accommodate various valve bore angles. By using the servo angle head 10 and the servo B-axis 8 in combination, the positional interference problem of traditional dual-spindle machining can be avoided, truly achieving parallel machining of bolt holes and valve bores, significantly improving machining efficiency.

[0024] The equipment is also equipped with auxiliary processing stations: a first disc-type tool magazine 4 is set on the upper left of the machine tool, which contains different specifications of valve hole drill bits 3 for valve hole drill bit replacement; a second disc-type tool magazine 16 is set on the upper right of the machine tool, which contains different specifications of bolt hole drill bits 17 for bolt hole drill bit replacement; and a chip conveyor 1 is set at the bottom of the machine tool to remove aluminum chips generated during the processing.

[0025] The chip conveyor 1 removes aluminum chips during machine tool processing. The bolt hole drill 15 and valve hole drill 11 are used for bolt hole machining. The first and second disc tool magazines 4 and 16 allow for drill bit replacement. The outer rim turning tool 19 is used for outer rim machining. The machine tool turning spindle 24 has an indexing function, enabling fixed-angle rotation, which rotates the aluminum wheel 22 to be machined to a preset angle. The first servo X-axis 5 drives the second moving platform 13 to move, bringing the bolt hole spindle 14 directly above the bolt hole. The second servo Z-axis feeds the bolt hole drill 15, achieving the target bolt hole machining. The machine tool spindle 24 then rotates the workpiece to a fixed angle, repeating the machining process to machine the next bolt hole. The machine tool spindle 24 uses its indexing function to rotate the valve hole of the aluminum wheel 22 to the target angle. The first servo X-axis 5 drives the first moving platform 7 to move. The first servo Z-axis 6, servo B-axis 8, and servo angle head 10 work together to achieve path interpolation, thus machining the valve hole according to the target position. The bed 2 is equipped with a turning and milling compound machining station. The machine tool turning spindle 24 is directly connected to the wheel fixture 23 for rotation, thereby driving the aluminum wheel 22 to rotate. The second servo X-axis 21 and the third servo Z-axis 18 jointly drive the third moving platform 23 to feed the outer rim turning tool 19, thereby realizing the turning machining of the aluminum wheel 22 and achieving the two turning processes of traditional wheel machining.

[0026] The working process of a single-station machining center for aluminum wheels, integrating two-stage and three-stage machining, is as follows: The machine tool receives communication information and knows the drill bit model required for the wheel to be processed. The first disc-type tool magazine 4 replaces the required valve hole drill bit; the second disc-type tool magazine 16 replaces the required bolt hole drill bit. The aluminum wheel 22 to be processed is placed on the wheel fixture 23, and the fixture clamps the wheel in preparation for processing. The machine tool turning spindle 24 rotates, and after reaching the predetermined speed, the third moving platform 20 drives the outer rim turning tool 19 to perform turning processing. After the turning processing is completed, the machine tool turning spindle 24 uses the indexing device to rotate the aluminum wheel 22 to be processed to the preset angle and fix it. The first moving platform 7, the valve hole spindle 9, the servo B-axis 8, and the servo angle head 10 cooperate to process the valve hole, while the second moving platform 13 and the bolt hole spindle 14 cooperate to process the bolt hole synchronously. During the processing, the chip conveyor 1 removes the aluminum chips generated during the processing. After the processing is completed, the wheel is removed and enters the next work cycle.

[0027] Compared with existing technologies, the aluminum wheel two- and three-stage integrated single-station machining center of the present invention has the following advantages:

[0028] This invention discloses a single-station machining center for aluminum wheels, integrating two-stage and three-stage machining processes. Based on parallel machining principles, it achieves a shorter process flow without increasing processing time. It can machine valve holes at different angles using an angle head paired with a servo B-axis, and integrates turning and drilling functions, replacing the two-stage turning and three-stage drilling of traditional wheel machining. Multi-stage parallel machining significantly improves processing efficiency; integrating two processes saves costs and floor space; and requiring only one milling-turning station eliminates positioning errors from secondary clamping, improving product quality.
