[0002] Traditional wheel hub machining systems require a first-stage, second-stage, and third-stage machining center. The first-stage center machine processes the outer rim (partially), inner rim, inner spokes, flange face, and center hole of the wheel hub. The second-stage center machine processes the outer rim (partially), outer spokes, and cap (cap stop + cap groove). The third-stage center machine processes the bolt holes and valve holes, and marks the ends of the valve holes. Furthermore, drilling the bolt holes and valve holes, and marking the ends of the valve holes are performed sequentially, which is time-consuming. In addition, the three machines forming a single machining system require a large floor space and are costly. Summary of the Invention

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] like Figure 1 As shown, an embodiment of the present invention provides a wheel hub turning and drilling composite machining equipment, including a bed 100, a workpiece spindle 200, a wheel hub fixture 300, a first machining device 400, and a second machining device 500.

[0022] The bed 100 is the main load-bearing structure, used to support other components.

[0023] The workpiece spindle 200 is mounted on the bed 100.

[0024] Specifically, the workpiece spindle 200 is set vertically, and the axis of the workpiece spindle 200 is perpendicular to the horizontal plane.

[0025] The hub fixture 300 is mounted on the workpiece spindle 200 and is used to hold the hub 10 to be processed.

[0026] Specifically, the hub fixture 300 is set at the top of the workpiece spindle 200. The hub fixture 300 is used to hold the hub 10 to be processed. When the hub 10 to be processed is held by the hub fixture 300, the axis of the hub 10 to be processed is coaxial with the axis of the workpiece spindle 200.

[0027] Combination Figure 1 and Figure 2The first processing device 400 is mounted on the bed 100 and is capable of processing the wheel hub 10 to be processed. The first processing device 400 includes a first drive mechanism 410, a first turret 420 drivenly connected to the first drive mechanism 410, and a bolt hole processing assembly 430 mounted on the first turret 420.

[0028] Specifically, the first turret 420 is located above the hub clamp 300, and the bolt hole machining assembly 430 is connected below the first turret 420 and located above the hub clamp 300.

[0029] It is understood that the first drive mechanism 410 is used to drive the first turret 420 to move, thereby moving the bolt hole processing assembly 430. The first turret 420 itself can also adjust the position of the bolt hole processing assembly 430. Thus, under the coordinated action of the first drive mechanism 410 and the first turret 420, the bolt hole processing assembly 430 can be moved to the corresponding position so that the bolt hole processing assembly 430 can process bolt holes 11 at the corresponding positions on the wheel hub 10 to be processed, which is held by the wheel hub fixture 300. It should be noted that in this embodiment, four bolt holes 11 need to be drilled on the wheel hub 10 to be processed. By adjusting the position of the bolt hole processing assembly 430, the four bolt holes 11 can be processed sequentially.

[0030] Specifically, the first drive mechanism 410 can drive the first turret 420 to move along a first direction, a second direction and a third direction, which are perpendicular to each other, wherein the first direction is parallel to the axis of the workpiece spindle 200.

[0031] It is understandable that when the first drive mechanism 410 drives the first turret 420 to move along the first direction, the bolt hole processing assembly 430 moves along the first direction with the first turret 420; when the first drive mechanism 410 drives the first turret 420 to move along the second direction, the bolt hole processing assembly 430 moves along the first turret 420 along the second direction; when the first drive mechanism 410 drives the first turret 420 to move along a third direction, the bolt hole processing assembly 430 moves along the first turret 420 along the third direction.

[0032] The first drive mechanism 410 includes a first translation drive 411, a second translation drive 412, and a third translation drive. The first translation drive 411 drives the first turret 420 to move along a first direction, the second translation drive 412 drives the first turret 420 to move along a second direction, and the third translation drive drives the first turret 420 to move along a third direction. The first translation drive 411, the second translation drive 412, and / or the third translation drive can be an electric lead screw.

[0033] Furthermore, the wheel hub machining combined machining equipment also includes a first slide 610 and a second slide 620. The second slide 620 can be driven by the second translation drive 412 to move along a second direction. The first slide 610 is slidably disposed on the second slide 620. The third translation drive can drive the first slide 610 to move along a third direction. The first turret 420 is disposed on the first slide 610. The first translation drive 411 can drive the first turret 420 to move along a first direction.

[0034] like Figure 4 As shown, the first turret 420 includes a first turret base 421, a first rotary drive assembly 422 disposed on the first turret base 421, and a first cutter head 423 drivenly connected to the first rotary drive assembly 422. The bolt hole machining assembly 430 has a bolt hole machining tool 431 disposed on the first cutter head 423.

[0035] Specifically, the first turret 421 is the main component that provides mounting positions for other parts of the first turret 420. The first turret 421 is slidably connected to the first slide table 610, and the first drive mechanism 410 is drivenly connected to the first turret 421. In the first direction, the first cutter head 423 is located on the side of the first turret 421 near the hub clamp 300. The first cutter head 423 is used to mount the bolt hole machining tool 431. The first cutter head 423 can be driven by the first rotary drive assembly 422 to rotate around the first rotation axis, and drive the bolt hole machining tool 431 to rotate around the first rotation axis. The first rotation axis is parallel to and spaced apart from the axis of the workpiece spindle 200.

[0036] Understandably, the first rotary drive assembly 422 can drive the first cutter head 423 to rotate around the first rotation axis, thereby causing the bolt hole machining tool 431 to rotate around the first rotation axis, thus adjusting the position of the bolt hole machining tool 431. When it is necessary to machine bolt holes 11 on the wheel hub 10 to be machined, the first drive mechanism 410 and the first rotary drive assembly 422 work together to drive the bolt hole machining tool 431 to move to the corresponding machining position, and the position of the bolt hole machining tool 431 can be adjusted by the first drive mechanism 410 to complete the machining of the bolt holes 11 on the wheel hub 10 to be machined.

[0037] It should be noted that the first rotary drive assembly 422 may include a motor and corresponding transmission components. The motor drives the first cutter head 423 to rotate around the first rotation axis through the transmission components.

[0038] like Figure 1As shown, the second processing device 500 is mounted on the bed 100. Specifically, the second processing device 500 is arranged side by side with the first processing device 400. In this embodiment, the second processing device 500 and the first processing device 400 are arranged side by side along a second direction. The second processing device 500 can also process the wheel hub 10 to be processed. It can be understood that the first processing device 400 is used to process a part of the structure of the wheel hub 10 to be processed, and the second processing device 500 is also used to process a part of the structure of the wheel hub 10 to be processed.

[0039] Combination Figure 1 , Figure 2 and Figure 3 The second processing device 500 includes a second drive mechanism 510, a second turret 520 drivenly connected to the second drive mechanism 510, and a valve hole drilling assembly 530 and a valve hole denting assembly 540 disposed on the second turret 520.

[0040] Specifically, the second turret 520 is located above the wheel hub clamp 300, and the valve bore drilling assembly 530 and the valve bore grooving assembly 540 are connected below the second turret 520 and located above the wheel hub clamp 300.

[0041] Understandably, the second drive mechanism 510 is used to drive the second turret 520 to move, thereby moving the valve bore drilling assembly 530 and the valve bore denting assembly 540. The second turret 520 itself can also adjust the position of the valve bore drilling assembly 530 and the valve bore denting assembly 540. Thus, under the coordinated action of the second drive mechanism 510 and the second turret 520, the valve bore drilling assembly 530 can be moved to the corresponding position first, so that the valve bore drilling assembly 530 drills the valve bore 12 at the corresponding position of the wheel hub 10 to be processed, which is held by the wheel hub chuck 300. Then, under the coordinated action of the second drive mechanism 510 and the second turret 520, the valve bore denting assembly 540 can be moved to the corresponding position first, so that the valve bore denting assembly 540 dents the valve bore 12.

[0042] Specifically, the second drive mechanism 510 can drive the second turret 520 to move along the first direction and the second direction.

[0043] Understandably, when the second drive mechanism 510 drives the second turret 520 to move in the first direction, the valve hole drilling assembly 530 and the valve hole denting assembly 540 move along with the second turret 520 in the first direction; when the second drive mechanism 510 drives the second turret 520 to move in the second direction, the valve hole drilling assembly 530 and the valve hole denting assembly 540 move along with the second turret 520 in the second direction.

[0044] The second drive mechanism 510 includes a fourth translation drive 511 and a fifth translation drive 512. The fourth translation drive 511 drives the second turret 520 to move along a first direction, and the fifth translation drive 512 drives the second turret 520 to move along a second direction. The fourth translation drive 511 and / or the fifth translation drive 512 may be electric lead screws.

[0045] Furthermore, the wheel hub machining combined machining equipment also includes a third slide 630; a fifth translation drive 512 is used to drive the third slide 630 to move along the second direction, the second turret 520 is slidably disposed on the third slide 630, and a fourth translation drive 511 is able to drive the second turret 520 to move along the first direction.

[0046] Of course, in other embodiments, the second drive mechanism 510 can also drive the second turret 520 to move in a third direction. When the second drive mechanism 510 drives the second turret 520 to move in a third direction, the valve hole drilling assembly 530 and the valve hole denting assembly 540 move along the second turret 520 in the third direction.

[0047] like Figure 5 As shown, in some embodiments, the second turret 520 includes a second turret base 521, a second rotary drive assembly 522 disposed on the second turret base 521, and a second cutter head 523 drivenly connected to the second rotary drive assembly 522. The valve hole drilling assembly 530 and the valve hole grooving assembly 540 are both disposed on the second cutter head 523.

[0048] Specifically, the second turret base 521 is the main component providing mounting positions for other parts of the second turret 520, and the second turret base 521 is slidably connected to the third slide table 630. The second drive mechanism 510 is drivenly connected to the second turret 520. In the first direction, the second cutter head 523 is disposed on the side of the second turret base 521 near the workpiece spindle 200. The second cutter head 523 is used to mount the valve hole drilling assembly 530 and the valve hole grooving assembly 540. The second cutter head 523 can be driven by the second rotary drive assembly 522 to rotate around the second rotation axis, and drive the valve hole drilling assembly 530 and the valve hole grooving assembly 540 to rotate around the second rotation axis. The second rotation axis is parallel to and spaced apart from the axis of the workpiece spindle 200.

[0049] Understandably, the second rotary drive assembly 522 can drive the second cutter head 523 to rotate around the second rotation axis, thereby causing the valve hole drilling assembly 530 and the valve hole scouring assembly 540 to rotate, thus adjusting the positions of the valve hole drilling assembly 530 and the valve hole scouring assembly 540. When it is necessary to machine the valve hole 12 on the wheel hub 10 to be processed, the second rotary drive assembly 522 drives the valve hole drilling assembly 530 to rotate to the corresponding processing position, and the position of the valve hole drilling assembly 530 can be adjusted by the second drive mechanism 510 to complete drilling the valve hole 12 on the wheel hub 10 to be processed. When it is necessary to scour the end of the valve hole 12, the second rotary drive assembly 522 drives the valve hole scouring assembly 540 to rotate to the corresponding processing position, and the position of the valve hole scouring assembly 540 can be adjusted by the second drive mechanism 510 to complete scouring the valve hole 12.

[0050] It should be noted that the second rotary drive assembly 522 may include a motor and corresponding transmission components. The motor drives the second cutter head 523 to rotate around the second rotation axis through the transmission components.

[0051] It should be noted that the valve bore drilling assembly 530 can be moved to the valve bore drilling position to drill the valve bore 12 on the wheel hub 10 to be processed, and the valve bore scouring assembly 540 can be moved to the valve bore scouring position to scour the end of the valve bore 12; wherein, the orientation of the valve bore drilling tool 531 of the valve bore drilling assembly 530 located at the valve bore drilling position is opposite to the orientation of the valve bore scouring tool 541 of the valve bore scouring assembly 540 located at the valve bore scouring position.

[0052] like Figure 2 As shown, specifically, the valve hole drilling assembly 530 can drill from top to bottom when drilling the valve hole 12 in the wheel hub 10 to be processed. Figure 3 , Figure 8 and Figure 9 As shown, when the valve bore grooving assembly 540 grooves the end of the valve bore 12, it can process from bottom to top. Compared with the traditional method, which uses a specific valve bore grooving tool to extend from the top of the valve bore 12 into the valve bore 12 and uses a reverse scraping method, this method can directly use general-purpose tools with shorter tool lengths, which can reduce the risk of vibration and make the processing more stable, reducing the risk of scratches.

[0053] like Figure 6 , Figure 7 As shown, it should be noted that the valve bore drilling tool 531 and the valve bore scouring tool 541 are both adjustable in angle and mounted on the second turret 520. Thus, the angles of the valve bore drilling tool 531 and the valve bore scouring tool 541 can be adjusted according to design requirements to meet various needs.

[0054] It should be further noted that in some embodiments, the first turret 420 and the second turret 520 are arranged in a horizontal direction; in other embodiments, the first turret 420 and the second turret 520 are arranged in a vertical direction.

[0055] In addition, both the first turret 420 and the second turret 520 are vertical, or both the first turret 420 and the second turret 520 are horizontal.

[0056] In operation, the wheel hub machining combined machining equipment of the present invention allows the first drive mechanism 410 and the first turret 420 to collaboratively drive the bolt hole machining assembly 430 to drill bolt holes 11 on the wheel hub 10 to be machined; the second drive mechanism 510 and the second turret 520 can first collaboratively drive the valve hole drilling assembly 530 to drill valve holes 12 on the wheel hub 10 to be machined, and then collaboratively drive the valve hole scouring assembly 540 to scour the end of the valve hole 12. Specifically, while the bolt hole machining assembly 430 is machining the bolt holes 11 on the wheel hub 10 to be machined, the valve hole drilling assembly 530 drills the valve holes 12 on the wheel hub, and then the valve hole scouring assembly 540 scours the end of the valve holes 12. In this way, the corresponding valve holes 12 can be machined on the wheel hub 10 to be machined while the bolt holes 11 are being machined, which can greatly save the corresponding machining time.

[0057] It should be noted that the first turret 420 can be equipped not only with the bolt hole machining assembly 430, but also with other machining assemblies, such as first other machining assemblies for machining the riser of the wheel hub 10 to be machined and for machining the front surface of the wheel hub 10 to be machined. Specifically, the first cutter head 423 can be equipped not only with the bolt hole machining assembly 430, but also with other cutting tools, such as first other cutting tools for machining the riser of the wheel hub 10 to be machined and for machining the front surface of the wheel hub 10 to be machined. The second turret 520 can be equipped not only with the valve hole drilling assembly 530 and the valve hole scouring assembly 540, but also with other second other machining assemblies, such as machining assemblies for machining the outer rim of the wheel hub 10 to be machined. Specifically, the second cutter head 523 can be equipped not only with the valve hole drilling assembly 530 and the valve hole scouring assembly 540, but also with other cutting tools, such as second other cutting tools for machining the outer rim of the wheel hub 10 to be machined.

[0058] While the first machining device 400 is machining the riser and front side of the wheel hub 10 to be machined, the second machining device 500 simultaneously completes the machining of the outer rim of the wheel hub 10 to be machined; while the first machining device 400 is machining the bolt holes, the second machining device 500 can also complete the drilling and denting of the valve holes; the coordinated machining of the first machining device 400 and the second machining device 500 can complete the traditional second and third stage machining while maintaining a basically the same machining cycle as the one-stage three-turret structure turning center, and equal to or slightly higher than the machining time of the traditional two-stage equipment.

[0059] It should be noted that in a traditional wheel hub machining system, a first-stage machine tool, a second-stage machine tool, and a third-stage machine tool are required. The first-stage machine tool is used to machine the outer rim (partial area), inner rim, inner spokes, flange face, and center hole of the wheel hub 10 to be machined. The second-stage machine tool is used to machine the outer rim (partial area), outer spokes, and cap opening (cap stop + cap groove) of the wheel hub 10 to be machined. The third-stage machine tool is used to machine the bolt holes and valve holes of the wheel hub 10 to be machined and to make grooves at the ends of the valve holes. By applying the wheel hub turning and drilling composite machining equipment of this application to a wheel hub machining system, the wheel hub machining system of this application can be used as a second-stage main machine. In this new wheel hub machining system, the first-stage main machine is used to machine the outer rim (partial area), inner rim, inner spokes, flange surface, and center hole of the wheel hub 10 to be machined. The wheel hub turning and drilling composite machining equipment of this application is used to machine the outer rim (partial area), outer spokes, cap opening (cap stop + cap groove), bolt holes, and valve holes of the wheel hub 10 to be machined, and to carve grooves at the ends of the valve holes. Thus, the new second-stage machining time is only slightly increased or equal to that of the traditional second-stage machining, but it reduces auxiliary time such as robot operation, thereby improving the system's machining efficiency.

[0060] In addition, the layout of traditional wheel hub processing systems is as follows: Figure 10 As shown, the layout of the wheel hub machining system using the wheel hub turning and drilling composite machining equipment of this application is as follows: Figure 11 As shown, the new wheel hub processing system has a more compact layout and higher space utilization.

[0061] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention.
