Description

Technical Field

[0001] The present invention relates to the technical field of machining equipment, and in particular to a wheel hub machining equipment. Background Art

[0002] Traditional wheel hub machining is divided into one-sequence machining, two-sequence machining, and three-sequence machining. The first, second, and third sequences are completed by three devices respectively; the main contents of the three-sequence machining are: bolt hole machining, valve hole machining, plug-in hole machining, etc. The wheel hubs with plug-in holes for new energy vehicles have a large number of plug-in holes, and the three-sequence machining time is long. In automated production, with the addition of auxiliary functions such as loading and unloading, wheel hub fixture flushing, and visual system position detection, the total time of the three sequences is much longer than that of the one-sequence machining and the two-sequence machining, resulting in a serious imbalance in the beats of the first, second, and third sequences of wheel hub machining.

[0003] The machining of forged wheel hubs is divided into one-sequence machining, three-sequence milling, and drilling machining; the main contents of the three-sequence machining are: milling the front face, spoke window, bolt hole machining, valve hole machining, plug-in hole machining, etc.; for forged wheel hubs, the three-sequence machining time is long. In automated production, combined with loading and unloading, wheel hub fixture washing, and visual system position detection, the total time of the three-sequence machining is much longer than that of the one-sequence machining, and the machining rhythm is seriously unbalanced.

[0004] Patent document with publication number CN118404122A discloses a wheel hub valve hole processing equipment, which has a loading and unloading position and a processing position. It can process the valve hole while loading and unloading, thereby improving efficiency. However, it tilts the wheel hub by setting an inclined placement plate to process a valve hole that meets the requirements. If the angle of the valve hole changes, it is necessary to replace the placement plate with a different angle, which is troublesome to operate. At the same time, the wheel hub valve hole processing equipment can only realize the processing of the valve hole and has a single function. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a wheel hub machining device that can process valve holes at different angles in a simple manner while having more comprehensive machining functions.

[0006] According to some embodiments of the present invention, the wheel hub machining equipment includes: a frame; a wheel hub clamping mechanism, which is arranged on the frame, the wheel hub clamping mechanism includes a rotating component, a first clamping component arranged on the rotating component, and a second clamping component arranged on the rotating component, the rotating component can drive the first clamping component and the second clamping component to rotate around a rotating axis at the same time, when one of the first clamping component and the second clamping component is in the first position, the other is in the second position, wherein the path of the first clamping component and the second clamping component rotating from the first position to the second position is a first path, and the path of the first clamping component and the second clamping component rotating from the second position to the first position is a second path, and both the first clamping component and the second clamping component can be controlled by the rotating component The wheel hub of the first clamping assembly is respectively located at the upper and lower material positions, the processing position and the valve hole processing position, and the wheel hub of the second clamping assembly is respectively located at the upper and lower material positions, the processing position and the valve hole processing position when the second clamping assembly is respectively located at the first position, the second position and the third position; the wheel hub of the second clamping assembly is respectively located at the upper and lower material positions, the processing position and the valve hole processing position; a processing mechanism is arranged on the frame, the processing mechanism has a main shaft, the main shaft is arranged toward the wheel hub clamping mechanism, and the main shaft is configured to be able to assemble a tool to process at least the front face, the spoke window and / or at least some types of holes of the wheel hub located at the processing position, and can also process the valve hole of the wheel hub located at the valve hole processing position.

[0007] The wheel hub machining equipment according to the embodiment of the present invention has at least the following beneficial effects:

[0008] The first clamping assembly is located at the first position, the second clamping assembly is located at the second position, and both the first clamping assembly and the second clamping assembly are unloaded, which is an initial state. One of the usage scenarios of the wheel hub machining apparatus of the present invention is:

[0009] First, the wheel hub is installed on the first clamping assembly; then, the rotating assembly works to drive the first clamping assembly to rotate from the first position to the second position, and at the same time drives the second clamping assembly to rotate from the second position to the first position; when the first clamping assembly is in the second position, the wheel hub on the first clamping assembly is in the processing position, at this time, the processing mechanism can process the wheel hub (for example, bolt holes, plug-in holes, front / spoke windows, etc.), while the processing mechanism is processing the wheel hub on the first clamping assembly, the second clamping assembly is in the first position, at this time, the second clamping assembly can be flushed, position detected by the visual system, and loaded, wherein, according to the actual situation of the wheel hub processing technology, the processing time of the wheel hub in the processing position is greater than the total time of the wheel hub in the loading and unloading positions and auxiliary functions, when the processing of the wheel hub in the processing position is completed, the clamping assembly in the first position has completed the loading and unloading and auxiliary functions, and is in a ready state; after processing and loading are completed, the rotating assembly works to drive The first clamping assembly rotates from the second position to the third position. At this time, the wheel hub on the first clamping assembly is in the valve hole processing position, and the processing mechanism can process the valve hole on the wheel hub. When the valve hole is added, the rotating assembly is activated to drive the first clamping assembly to rotate from the third position to the first position, and at the same time drive the second clamping assembly to rotate to the second position. When the first clamping assembly is in the first position, the wheel hub on the first clamping assembly can be unloaded and a new wheel hub to be processed can be loaded. At this time, the second clamping assembly is in the second position, and the processing mechanism can process the wheel hub on the second clamping assembly. After processing and loading are completed, the rotating assembly is activated to drive the second clamping assembly to rotate from the second position to the third position. At this time, the wheel hub on the second clamping assembly is in the valve hole processing position, and the processing mechanism can process the valve hole on the wheel hub. When the valve hole is added, the rotating assembly is activated to drive the second clamping assembly to rotate from the third position to the first position, and at the same time drive the first clamping assembly to rotate to the second position. Thereafter, the above steps can be repeated to alternately process the wheel hubs on the first clamping assembly and the second clamping assembly.

[0010] The first clamping assembly is located at the first position, the second clamping assembly is located at the second position, and the first clamping assembly and the second clamping assembly are unloaded as the initial state. Another use case of the wheel hub machining device of the present invention is:

[0011] First, the wheel hub is installed on the first clamping assembly; then, the rotating assembly works to drive the first clamping assembly to rotate from the first position to the third position. At this time, the wheel hub on the first clamping assembly is in the valve hole processing position, and the processing mechanism can process the valve hole on the wheel hub; when the valve hole addition is completed, the rotating assembly works to drive the first clamping assembly to rotate from the third position to the second position, and at the same time drives the second clamping assembly to rotate to the first position; when the first clamping assembly is in the second position, the wheel hub on the first clamping assembly is in the processing position. At this time, the processing mechanism can process the wheel hub (for example, bolt holes, plug-in holes, front / spoke windows, etc.). While the processing mechanism is processing the wheel hub on the first clamping assembly, the second clamping assembly located in the first position can be flushed, the visual system position is detected, and the material is loaded. Among them, according to the actual situation of the wheel hub processing technology, the processing time of the wheel hub in the processing position is longer than the time when the wheel hub is in the loading and unloading position for loading and unloading and auxiliary Total function time: When the processing of the hub in the processing position is completed, the clamping assembly in the first position has completed the loading and unloading and auxiliary functions and is in a ready state; when the processing and loading are completed, the rotating assembly works to drive the second clamping assembly to rotate from the first position to the third position. At this time, the hub on the second clamping assembly is in the valve hole processing position, and the processing mechanism can process the valve hole on the hub; when the valve hole addition is completed, the rotating assembly works to drive the second clamping assembly from the third position to the second position, and at the same time drives the first clamping assembly to rotate to the first position; when the second clamping assembly is in the second position, the hub on the second clamping assembly is in the processing position. At this time, the processing mechanism can process the hub (for example, bolt holes, plug-in holes, front / spoke windows, etc.). While the processing mechanism is processing the hub on the second clamping assembly, it can load and unload the hub on the first clamping assembly in the first position. Afterwards, the above steps can be repeated to alternately process the hubs on the first clamping assembly and the second clamping assembly.

[0012] It is understandable that when the hub machining equipment of the present invention is in use, when the hub on one of the clamping assemblies is in the processing position, loading and unloading can be carried out on the other clamping assembly. In this way, the auxiliary time required for additional loading and unloading, hub fixture flushing, and visual system position detection is saved, which greatly improves the hub processing production efficiency, shortens the total processing time of the three-sequence hub machine tool, balances the entire hub processing cycle, and greatly shortens the total hub processing cycle. In addition, when the hub machining equipment of the present invention is in use, the angle of the hub can be adjusted by means of the rotating assembly so that it meets the angle deflection requirements of the valve hole processing, optimizes the machine tool structure, eliminates the need to set up another set of rotating mechanisms, and reduces the equipment cost. Moreover, no matter what the design value of the valve hole angle is, the rotating assembly can be used to adjust the specific position of the third position to meet the valve hole processing requirements.

[0013] According to some embodiments of the present invention, the first path and the second path form a circular path, or the first path and the second path are two paths in opposite directions.

[0014] According to some embodiments of the present invention, the rotating assembly includes a driving source and a turntable drivingly connected to the driving source, and the first clamping assembly and the second clamping assembly are both disposed on the turntable.

[0015] According to some embodiments of the present invention, the rotation axis of the turntable is vertical.

[0016] According to some embodiments of the present invention, a central axis of a hub mounted on the first clamping assembly and / or the second clamping assembly is horizontal.

[0017] According to some embodiments of the present invention, the central axis of the main shaft is horizontal.

[0018] According to some embodiments of the present invention, an inclined chip removal surface is provided on the frame, and the chip removal surface is located below the area between the main shaft and the processing position. A chip removal groove is provided at the bottom of the chip removal surface, and the wheel hub machining equipment also includes a chip conveyor for discharging chips in the chip removal groove.

[0019] According to some embodiments of the present invention, the processing mechanism further includes a displacement assembly, which is used to drive the spindle to feed so that the stroke of the spindle meets the processing requirements of the wheel hub.

[0020] According to some embodiments of the present invention, there are multiple first clamping assemblies, and there are multiple second clamping assemblies, and the number of the second clamping assemblies is equal to the number of the first clamping assemblies. The multiple first clamping assemblies and the multiple second clamping assemblies are arranged back to back in a one-to-one correspondence, and the processing mechanism has multiple spindles.

[0021] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0044] Example 1:

[0045] like Figure 1 As shown, the wheel hub machining equipment provided in the first embodiment of the present invention, specifically in this embodiment, is a horizontal structure, which includes a frame 100, a wheel hub clamping mechanism 200 and a machining mechanism 300.

[0046] The frame 100 is the main supporting mechanism.

[0047] The wheel hub clamping mechanism 200 is disposed on the frame 100 , and the wheel hub clamping mechanism 200 is used to clamp the wheel hub 10 .

[0048] Combine Figure 2 and Figure 4 The wheel hub clamping mechanism 200 includes a rotating assembly 210 , a first clamping assembly 220 disposed on the rotating assembly 210 , and a second clamping assembly 230 disposed on the rotating assembly 210 .

[0049] Specifically, the rotating assembly 210 is rotatably disposed on the frame 100 and includes a rotating drive source 211 and a turntable 212 drivingly connected to the rotating drive source 211. The rotating drive source 211 is indirectly or directly disposed on the frame 100. The driving shaft of the rotating drive source 211 is connected to the turntable 212. The rotating drive source 211 can drive the turntable 212 to rotate around the axis (rotation axis) of the turntable 212. The rotating drive source 211 can be a motor.

[0050] Furthermore, a support frame 400 is further provided on the frame 100 , the rotation driving source 211 is provided on the support frame 400 , the turntable 212 is rotatably connected to the support frame 400 , and the turntable 212 can rotate relative to the support frame 400 .

[0051] Furthermore, the rotation axis of the turntable 212 is arranged perpendicular to the horizontal plane. In other words, the axial direction of the rotation axis of the turntable 212 is the vertical direction, and the rotation driving source 211 is used to drive the turntable 212 to rotate around the rotation axis of the turntable 212.

[0052] The first clamping assembly 220 and the second clamping assembly 230 are both fixed on the turntable 212 . When the turntable 212 rotates, it can drive the first clamping assembly 220 and the second clamping assembly 230 to rotate together around the rotation axis of the turntable 212 .

[0053] Furthermore, both the first clamping assembly 220 and the second clamping assembly 230 can be used to clamp the wheel hub 10. When the first clamping assembly 220 and the second clamping assembly 230 clamp the wheel hub 10, the central axis of the wheel hub 10 is horizontal. When the turntable 212 rotates under the drive of the rotary drive source 211, the wheel hub 10 clamped by the first clamping assembly 220 and the second clamping assembly 230 also rotates about the rotation axis of the turntable 212.

[0054] When the first clamping assembly 220 is located at the first position ( Figure 4 The first clamping assembly 220 is located in the position), the second clamping assembly 230 is located in the second position ( Figure 4 When the first clamping assembly 220 is in the second position, the first clamping assembly 220 is in the first position. It is understood that the first clamping assembly 220, driven by the rotating assembly 210, can rotate from the first position to the second position. During this process, the second clamping assembly 230, driven by the rotating assembly 210, rotates from the second position to the first position.

[0055] Further, the position of the hub 10 on the first clamping assembly 220 located at the first position is defined as the upper and lower material positions 11 . It can be understood that the position of the hub 10 on the second clamping assembly 230 located at the first position is also the upper and lower material positions 11 .

[0056] Specifically, both the first clamping assembly 220 and the second clamping assembly 230 can clamp the wheel hub 10. When the unloaded first clamping assembly 220 rotates to the first position, the wheel hub 10 can be loaded so that the wheel hub 10 is clamped by the first clamping assembly 220. When the first clamping assembly 220 that has clamped the wheel hub 10 rotates to the first position, the wheel hub 10 can be removed from the first clamping assembly 220. It is also understandable that when the unloaded second clamping assembly 230 rotates to the first position, the wheel hub 10 can be loaded so that the wheel hub 10 is clamped by the second clamping assembly 230. When the second clamping assembly 230 that has clamped the wheel hub 10 rotates to the first position, the wheel hub 10 can be removed from the second clamping assembly 230.

[0057] Furthermore, the position of the hub 10 on the first clamping assembly 220 in the second position is defined as the processing position 12. It is understood that the position of the hub 10 on the second clamping assembly 230 in the second position is also the processing position 12. The processing mechanism 300 can process certain types of holes, front surfaces, and spoke windows on the hub 10 located in the processing position 12. Specifically, the processing mechanism 300 can process holes and surfaces such as bolt holes, plug-in holes, front surfaces, and spoke windows on the hub 10 located in the processing position 12.

[0058] Furthermore, the path for the first clamping assembly 220 to rotate from the first position to the second position is the first path, and the path for the second clamping assembly 230 to rotate from the first position to the second position is also the first path; the path for the first clamping assembly 220 to rotate from the second position to the first position is the second path, and the path for the second clamping assembly 230 to rotate from the second position to the first position is also the second path. The first clamping assembly 220 can be controlled by the rotation assembly 210 to stop and remain at the third position within the first path, and the second clamping assembly 230 can also be controlled by the rotation assembly 210 to stop and remain at the third position within the first path. In other embodiments, the third position is located along the second path.

[0059] In some embodiments, the first path and the second path form a circular path; in other embodiments, the first path and the second path are two paths in opposite directions.

[0060] It should be noted that when the first clamping assembly 220 is located at the third position, the wheel hub 10 on the first clamping assembly 220 is located at the valve hole processing position 13 ( Figure 5 、 Figure 6The processing mechanism 300 is capable of processing the valve hole 14 on the wheel hub 10 located at the valve hole processing position 13; it can be understood that when the second clamping assembly 230 is located at the third position, the wheel hub 10 on the second clamping assembly 230 is located at the valve hole processing position 13.

[0061] It should be further explained that the processing mechanism 300 is disposed on the frame 100 and is spaced apart horizontally from the wheel hub clamping mechanism 200. The processing mechanism 300 has a spindle 310, the central axis of which is horizontal. The spindle 310 can be equipped with a tool to perform processing. The spindle 310 is perpendicular to the rotation axis of the turntable 212. When the wheel hub 10 is in the processing position 12, the axis of the wheel hub 10 is parallel to the spindle 310. At this time, the tool on the spindle 310 can process bolt holes and plug-in holes in the wheel hub 10 (the axes of the bolt holes and plug-in holes are parallel to the axis of the wheel hub 10). When the wheel hub 10 is in the valve hole processing position 13, the axis of the wheel hub 10 forms a certain angle with the spindle 310. At this time, the tool on the spindle 310 can process the valve hole 14 in the wheel hub 10 (the axis of the valve hole 14 forms a certain angle with the axis of the wheel hub 10).

[0062] It will be appreciated that the specific location of the third position can be determined based on the design value of the angle between the axis of the valve hole and the axis of the wheel hub 10. Specifically, by ensuring that the angle between the axis of the spindle 310 and the axis of the wheel hub 10 located at the valve hole machining position 13 is the same as the design value of the angle between the axis of the valve hole and the axis of the wheel hub 10, or is within the allowable error range, the tool on the spindle 310 can machine a desired valve hole on the wheel hub 10 located at the valve hole machining position 13.

[0063] Combine Figure 1 and Figure 2 It is understandable that the processing mechanism 300 further includes a displacement assembly 330 , which can drive the spindle 310 to feed so that the stroke of the spindle 310 meets the processing requirements of the wheel hub 10 .

[0064] Combine Figure 2 and Figure 3 Specifically, the displacement assembly 330 includes a first drive member 331, a second drive member 332, and a third drive member 333. Specifically, the first drive member 331, the second drive member 332, and the third drive member 333 respectively drive the main shaft 310 to move in three mutually perpendicular directions. The first drive member 331 is used to drive the main shaft 310 along its axial direction. The first drive member 331, the second drive member 332, and the third drive member 333 can be linear drive mechanisms such as pneumatic cylinders, oil cylinders, and electric lead screws.

[0065] Furthermore, the processing mechanism 300 also includes a spindle box 320, the spindle 310 is connected to the spindle box 320, the spindle box 320 is arranged on the displacement assembly 330, and the displacement assembly 330 also includes a first slide 334 and a second slide 335. The first slide 334 is used to move the spindle box 320 in the horizontal plane and to move the spindle box 320 in the vertical direction.

[0066] It should be noted that the second slide 335 can be disposed on the first slide 334. In other embodiments, the first slide 334 can also be disposed on the second slide 335. It is understood that the guide structure for guiding the spindle housing 320 is not limited to the above-mentioned slide.

[0067] It is understandable that the spindle 310 moves under the drive of the displacement assembly 330 , thereby adjusting its position and processing different positions on the wheel hub 10 .

[0068] The first clamping assembly 220 is located at the first position, the second clamping assembly 230 is located at the second position, and both the first clamping assembly 220 and the second clamping assembly 230 are unloaded as an initial state. One of the usage scenarios of the wheel hub machining apparatus of the present invention is:

[0069] First, the wheel hub 10 is installed on the first clamping assembly 220; then, the rotating assembly 210 works to drive the first clamping assembly 220 to rotate from the first position to the second position, and at the same time drives the second clamping assembly 230 to rotate from the second position to the first position; when the first clamping assembly 220 is in the second position, the wheel hub 10 on the first clamping assembly 220 is in the processing position 12, at this time, the processing mechanism 300 can process the wheel hub 10 (for example, processing bolt holes, plug-in holes, front / spoke windows, etc.), while the processing mechanism 300 processes the wheel hub 10 on the first clamping assembly 220 When the wheel hub is in the processing position, the second clamping assembly is in the first position. At this time, the second clamping assembly 230 can be flushed, the visual system position is detected, and the material is loaded. According to the actual situation of the wheel hub processing technology, the processing time of the wheel hub in the processing position is greater than the total time of the wheel hub in the loading and unloading position and the auxiliary functions. When the wheel hub in the processing position is processed, the clamping assembly in the first position has completed the loading and unloading and auxiliary functions and is in a ready state; after the processing and loading are completed, the rotating assembly 210 works to drive the first clamping assembly 220 to rotate from the second position to the third position. At this time, the first clamping assembly 22 0 is in the valve hole processing position 13, and the processing mechanism 300 can process the valve hole on the wheel hub 10; when the valve hole addition is completed, the rotating component 210 works to drive the first clamping component 220 to rotate from the third position to the first position, and at the same time drives the second clamping component 230 to rotate to the second position; when the first clamping component 220 is in the first position, at this time, the wheel hub 10 on the first clamping component 220 is in the loading and unloading position 11, the wheel hub 10 on the first clamping component 220 can be unloaded and a new wheel hub 10 to be processed can be loaded, at this time, the wheel hub 10 on the second clamping component 230 The hub 10 is in the processing position, and the processing mechanism 300 can process the hub 10 on the second clamping assembly 230. After processing and loading are completed, the rotating assembly 210 operates to drive the second clamping assembly 230 to rotate from the second position to the third position. At this time, the hub 10 on the second clamping assembly 230 is in the valve hole processing position 13, and the processing mechanism 300 can process the valve hole on the hub 10. After the valve hole is added, the rotating assembly 210 operates to drive the second clamping assembly 230 to rotate from the third position to the first position, and simultaneously drives the first clamping assembly 220 to rotate to the second position. Afterwards, the above steps can be repeated to alternately process the hub 10 on the first clamping assembly 220 and the second clamping assembly 230.

[0070] The first clamping assembly 220 is located at the first position, the second clamping assembly 230 is located at the second position, and the first clamping assembly 220 and the second clamping assembly 230 are unloaded as the initial state. Another use case of the wheel hub machining equipment of the present invention is:

[0071] First, the wheel hub 10 is installed on the first clamping assembly 220; then, the rotating assembly 210 works to drive the first clamping assembly 220 to rotate from the first position to the third position. At this time, the wheel hub 10 on the first clamping assembly 220 is in the valve hole processing position 13, and the processing mechanism 300 can process the valve hole on the wheel hub 10; when the valve hole addition is completed, the rotating assembly 210 works to drive the first clamping assembly 220 to rotate from the third position to the second position, and at the same time drives the second clamping assembly 230 to rotate to the first position; when the first clamping assembly 220 is in the valve hole processing position 13, ... When in the second position, the wheel hub 10 on the first clamping assembly 220 is in the processing position 12. At this time, the processing mechanism 300 can process the wheel hub 10 (for example, processing of bolt holes, plug-in holes, front / spoke windows, etc.). While the processing mechanism 300 is processing the wheel hub 10 on the first clamping assembly 220, the second clamping assembly 230 can be flushed, position detected by the visual system, and loaded. According to the actual situation of the wheel hub processing technology, the processing time of the wheel hub in the processing position is longer than the total time of the wheel hub in the loading and unloading position for loading and unloading and auxiliary functions. When the wheel hub in the processing position is processed, the clamping assembly in the first position has completed the loading and unloading and auxiliary functions and is in a ready state; when the processing and loading are completed, the rotating assembly 210 works to drive the second clamping assembly 230 to rotate from the first position to the third position. At this time, the wheel hub 10 on the second clamping assembly 230 is in the valve hole processing position 13, and the processing mechanism 300 can process the valve hole on the wheel hub 10; when the valve hole addition is completed, the rotating assembly 210 works to drive the second clamping assembly 230 from the third position to the third position. The first clamping assembly 220 is rotated to the second position and simultaneously drives the first clamping assembly 220 to rotate to the first position. When the second clamping assembly 230 is in the second position, the hub 10 on the second clamping assembly 230 is in the processing position 12. At this time, the processing mechanism 300 can process the hub 10 (for example, processing bolt holes, plug-in holes, front / spoke windows, etc.). While the processing mechanism 300 is processing the hub 10 on the second clamping assembly 230, it can also load and unload the hub 10 on the first clamping assembly 220 in the first position. Afterwards, the above steps can be repeated to alternately process the hub 10 on the first clamping assembly 220 and the second clamping assembly 230.

[0072] It is understandable that when the hub machining equipment of the present invention is in use, when the hub 10 on one of the clamping assemblies is in the processing position 12 for processing, loading and unloading can be carried out on the other clamping assembly. In this way, the auxiliary time required for additional loading and unloading, hub fixture flushing, and visual system position detection is saved, which greatly improves the hub processing production efficiency, shortens the total processing time of the three-sequence hub machine tool, balances the entire hub processing cycle, and greatly shortens the total hub processing cycle. In addition, when the hub machining equipment of the present invention is in use, the angle of the hub 10 can be adjusted by means of the rotating assembly 210 so that it meets the angle deflection requirements of the valve hole processing, optimizes the machine tool structure, eliminates the need to set up another set of rotating mechanisms, and reduces the equipment cost. Moreover, no matter what the design value of the valve hole angle is, the rotating assembly 210 can be used to adjust the specific position of the third position to meet the valve hole processing requirements.

[0073] like Figure 1 As shown, the frame 100 is further provided with an inclined chip discharge surface 500, which is located below the area between the spindle 310 and the machining station 12. A chip discharge groove 600 is provided at the bottom of the chip discharge surface 500. The wheel hub machining equipment also includes a chip conveyor 700 for discharging chips in the chip discharge groove 600. In this way, the generated discharge can be discharged in a timely manner.

[0074] Furthermore, both the rotating assembly 210 and the processing mechanism 300 adopt protective measures to prevent chips generated during processing from entering the interior of the rotating assembly 210 and the processing mechanism 300.

[0075] It should be noted that the wheel hub machining equipment further includes a tool magazine 800 arranged on the frame 100 .

[0076] Example 2:

[0077] like Figure 7 As shown, there are two first clamping assemblies 220 and two second clamping assemblies 230. The two first clamping assemblies 220 and the two second clamping assemblies 230 are arranged opposite each other in a one-to-one correspondence. The processing mechanism 300 has multiple spindles 310. This embodiment can realize dual loading and unloading positions 11, dual processing positions 12, and dual valve hole processing positions 13, further improving efficiency.

[0078] It is understandable that in other embodiments, the number of the corresponding first clamping assembly 220, the second clamping assembly 230 and the main shaft 310 can also be set to more than three.

[0079] It is understandable that when the hub machining equipment of the present invention is in use, when the hub 10 on one of the clamping assemblies is in the processing position 12 for processing, loading and unloading can be carried out on the other clamping assembly. In this way, the auxiliary time required for additional loading and unloading, hub fixture flushing, and visual system position detection is saved, which greatly improves the hub processing production efficiency, shortens the total processing time of the three-sequence hub machine tool, balances the entire hub processing cycle, and greatly shortens the total hub processing cycle. In addition, when the hub machining equipment of the present invention is in use, the angle of the hub 10 can be adjusted by means of the rotating assembly 210 so that it meets the angle deflection requirements of the valve hole processing, optimizes the machine tool structure, eliminates the need to set up another set of rotating mechanisms, and reduces the equipment cost. Moreover, no matter what the design value of the valve hole angle is, the rotating assembly 210 can be used to adjust the specific position of the third position to meet the valve hole processing requirements.

[0080] Example 3:

[0081] like Figure 8 As shown, the wheel hub machining equipment involved in the third embodiment of the present invention, wherein the main difference from the first embodiment lies in the displacement assembly 330. In the third embodiment, the third slide 336 is arranged on the second slide 335, and the spindle housing 320 is arranged on the third slide 336. Among them, the first driving member 331 is arranged on the third slide 336, and the first driving member 331 can drive the spindle housing 320 and the spindle 310 to move in a direction parallel to the axial direction of the spindle 310. Specifically, the first driving member 331 can drive the spindle housing 320 and the spindle 310 to move along the third slide 336 toward the wheel hub clamping mechanism 200 or move away from the wheel hub clamping mechanism 200, so as to facilitate the processing of the wheel hub 10.
