Description

Technical Field

[0001] This utility model relates to the field of machining technology, and more specifically, to a five-axis machining center for wheel hubs. Background Technology

[0002] A five-axis machining center, also known as a five-axis linkage machining center, is a high-tech, high-precision machining center specifically designed for machining complex curved surfaces. It has five axes that enable five-axis linkage machining and is adept at machining spatial curved surfaces, irregular shapes, hollowing, drilling, oblique holes, and bevel cutting.

[0003] Currently, wheel hub machining is usually completed in a five-axis machining center. The five-axis machining center adjusts the position through the XYZ three axes and adjusts the angle through the AC or BC two axes, enabling the wheel hub to be milled in all directions in three-dimensional space. However, after the existing five-axis machining center has finished machining the wheel hub, it usually needs to be manually removed from the machining center. Since the wheel hub has a certain weight, it is easy to get tired by manually removing the wheel hub for a long time, and the manual material removal speed is slow, resulting in low work efficiency.

[0027] Example:

[0028] Please see Figure 1-5 A five-axis machining center for wheel hubs includes a base 1, a three-axis guide rail module 2 at the top of the base 1, a drive motor 3 on the three-axis guide rail module 2, a milling cutter 4 fixedly connected to the output end of the drive motor 3, a cradle turntable 5 fixedly connected inside the base 1, a horizontal turntable 6 inside the cradle turntable 5, a positioning chuck 7 fixedly connected to the top of the horizontal turntable 6, and the positioning chuck 7 corresponding to the milling cutter 4; and a lifting cylinder module 8 fixedly connected to one side of the base 1. A lifting frame 9 is fixedly connected to the output end. A multi-stage telescopic electric cylinder 10 is fixedly connected to one side of the lifting frame 9. A slide 11 is fixedly connected to the output end of the multi-stage telescopic electric cylinder 10. The slide 11 is slidably connected to the inner side of the lifting frame 9. A rotating frame 12 is rotatably connected to the inner side wall of the slide 11. The rotating frame 12 corresponds to the cradle turntable 5. A push-pull cylinder module 13 is movably hinged to the bottom of the slide 11 through a hinge shaft. The output end of the push-pull cylinder module 13 is movably hinged to one side of the rotating frame 12 through a hinge shaft.

[0029] In this embodiment, during the milling of the wheel hub, the wheel hub is placed on the horizontal turntable 6 and positioned using the positioning chuck 7. The three-axis guide rail module 2 drives the drive motor 3 to move along the XYZ axes, adjusting the position of the milling cutter 4 to correspond with the wheel hub. The cradle turntable 5 and the horizontal turntable 6 drive the wheel hub to rotate along the A and C axes, adjusting the wheel hub's machining position. This, combined with the milling cutter 4, enables five-axis multi-directional machining. After the wheel hub machining is completed, the three-axis guide rail module 2 drives the drive motor 3 and the milling cutter 4 to reset. The reset of the drive motor 3 and the milling cutter 4 does not affect the removal of the wheel hub. The cradle turntable 5 drives the horizontal turntable 6 and the positioning chuck 7 to reset the wheel hub. The wheel hub is placed horizontally. Then, the positioning chuck 7 releases the wheel hub from its fixation. The multi-stage telescopic electric cylinder 10 pushes the slide 11 to slide inside the lifting frame 9. The slide 11 drives the rotating frame 12 to insert into the cradle turntable 5 and be located below the wheel hub. The lifting cylinder module 8 controls the lifting frame 9 to rise. The lifting frame 9 drives the slide 11 and the rotating frame 12 to rise, so that the rotating frame 12 lifts the wheel hub from the horizontal turntable 6. The wheel hub moves to the upper side of the positioning chuck 7. The push-pull cylinder module 13 pushes the rear end of the rotating frame 12 to rotate slightly upward inside the slide 11. The rotating frame 12 tilts inside the slide 11, so that the wheel hub slides forward out of the machining center to enter the next process.

[0030] Specifically, an auxiliary rod assembly 14 is fixedly connected to the bottom of the lifting frame 9, and the auxiliary rod assembly 14 is slidably inserted into the base 1.

[0031] In this embodiment, when the lifting cylinder module 8 controls the lifting frame 9 to rise, the auxiliary rod group 14 slides within the base 1 to ensure the stability of the lifting frame 9 during the lifting process.

[0032] Specifically, the inner wall of the lifting frame 9 is provided with a sliding groove 15, and the outer surface of the slide frame 11 is fixedly connected with a sliding strip 16, which is slidably connected in the sliding groove 15.

[0033] In this embodiment, when the multi-stage telescopic electric cylinder 10 controls the slide 11 to slide inside the lifting frame 9, the slide 11 drives the slide bar 16 to slide in the slide groove 15. The sliding connection between the slide bar 16 and the slide groove 15 keeps the movement of the slide 11 stable.

[0034] Specifically, two sets of rollers 17 are rotatably connected inside the rotating frame 12, and the two sets of rollers 17 are symmetrically distributed.

[0035] In this embodiment, when the rotating frame 12 tilts and the hub slides out of the machining center, the two sets of internal rollers 17 make the hub slide out more smoothly.

[0036] Specifically, a support platform 18 is fixedly connected to the top of the base 1, and a three-axis guide rail module 2 is fixedly connected to the top of the support platform 18.

[0037] In this embodiment, the support platform 18 is used to support the three-axis guide rail module 2, so that the three-axis guide rail module 2 can be kept at the required height to control the movement of the drive motor 3 and the milling cutter 4.

[0038] Specifically, a waste removal channel 19 is fixedly connected inside the base 1, and one end of the waste removal channel 19 extends through to one side of the base 1.

[0039] In this embodiment, the impurities generated by the milling cutter 4 during wheel hub milling will fall into the machine base 1, and the impurity discharge channel 19 in the machine base 1 will collect and discharge the impurities.

[0040] Working principle: When machining the wheel hub, the wheel hub is placed on the horizontal turntable 6 and positioned using the positioning chuck 7. The three-axis guide rail module 2 drives the drive motor 3 to move along three axes, adjusting the position of the milling cutter 4 to correspond with the wheel hub. The cradle turntable 5 and the horizontal turntable 6 drive the wheel hub to rotate along two axes, adjusting the wheel hub's machining position. The wheel hub position adjustment, combined with the milling cutter 4 position adjustment, achieves five-axis multi-directional machining. After machining, the three-axis guide rail module 2 drives the drive motor 3 and the milling cutter 4 to reset. The cradle turntable 5 drives the horizontal turntable 6 and the positioning chuck 7 to place the wheel hub horizontally. Then, the positioning chuck 7 releases the wheel hub from its fixation. The multi-stage telescopic electric cylinder 10 pushes the slide 11 to slide inside the lifting frame 9. The slide 11 drives the turntable 12 to insert into the cradle. The turntable 5 is located below the wheel hub. The lifting cylinder module 8 controls the lifting frame 9 to rise. The lifting frame 9 drives the slide 11 and the turntable 12 to rise, so that the turntable 12 lifts the wheel hub from the horizontal turntable 6 to the upper side of the positioning chuck 7. The push-pull cylinder module 13 pushes the rear end of the turntable 12 to rotate upward in the slide 11. The turntable 12 tilts slightly in the slide 11, so that the wheel hub slides forward in the turntable 12 to enter the next processing step in the machining center. After the wheel hub is removed, the push-pull cylinder module 13 pulls the turntable 12 to reset in the slide 11. The multi-stage telescopic electric cylinder 10 controls the slide 11 and the turntable 12 to reset. The lifting cylinder module 8 controls the lifting frame 9 to move down and reset, so that the turntable 12 retracts to the rear side of the cradle turntable 5, which facilitates the removal of subsequent wheel hubs.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
