Description

Technical Field

[0001] This invention belongs to the field of wheel hub turning, specifically relating to turning equipment and methods for correcting runout on the end face of aluminum alloy wheel hubs. Background Technology

[0002] This is a special CNC lathe designed specifically for the excessive runout of the flange mounting end face of automotive aluminum alloy wheel hubs. Its core function is to smooth the annular flange end face that is attached to the brake disc on the inner side of the wheel hub through automatic scanning detection and micro-precision turning.

[0003] Patent publication number CN221952337U relates to a cutting tool for turning wheel hubs. The tool includes a tool shank with a hook at its front end. An insert for turning the center hole and cap groove of the wheel hub is detachably connected to the end of the hook, allowing the insert to be fixed to the tool shank at a certain rotation angle. This patent, by setting the hook, allows the insert to be fixed to the tool shank at a certain rotation angle, enabling the tool to extend from the front of the wheel hub riser and perform reverse turning of the center hole and cap groove across the cap groove face. This solves the problem that traditional turning tools are not suitable for turning specially shaped wheel hubs, optimizes the machining process for specially shaped wheel hubs, and improves machining efficiency. Simultaneously, the patent, through the setting of a positioning structure, ensures the radial and axial positioning accuracy of the tool and effectively avoids radial rotation of the tool due to torque during machining, ensuring machining accuracy.

[0004] In existing technologies, by setting up a positioning structure, the radial and axial positioning accuracy of the tool is ensured, and the radial rotation of the tool due to torque during the machining process is effectively avoided, thus ensuring machining accuracy. However, during the turning of wheel hubs, the temperature of the aluminum chips generated can reach several hundred degrees Celsius. The chips melt and adhere to the inner side of the wheel hub, forming hard aluminum lumps, which affect the stability of the wheel hub. At the same time, when the wheel hub needs to be removed, the wheel hub is too heavy and may fall directly to the ground, causing the wheel hub to be bumped and damaged, affecting normal use. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this disclosure provides a turning equipment and method for correcting runout on the end face of aluminum alloy wheel hubs. According to a first aspect of the present disclosure, a turning device for correcting runout of an aluminum alloy wheel hub end face is provided: comprising: a lathe, wherein a turning device is provided inside the lathe, a fixed table is provided inside the lathe, a wheel hub is provided on the surface of the fixed table, a linear motor is fixedly mounted on the surface of the fixed table, a limit block is fixedly mounted on the output end of the linear motor, a ring is fixedly mounted on the surface of the limit block, a circular plate is slidably mounted on the inner wall of the ring, a fixed plate is fixedly mounted on the surface of the linear motor, and a guide wheel is rotatably mounted on the surface of the limit block. A belt is fixedly installed on the surface of the plate. The end of the belt away from the fixed plate is fixedly installed on the surface of the circular plate. A groove is opened on the surface of the circular plate. An L-shaped slide rod is slidably installed on the inner wall of the groove. There are four L-shaped slide rods. A guide groove is opened on the inner wall of the circular ring. The L-shaped slide rods are slidably connected to the guide groove. When the circular plate moves towards the limiting block, it will drive the L-shaped slide rods to move towards the limiting block. When the L-shaped slide rods move towards the limiting block, they will slide along the guide groove, so that the upper and lower L-shaped slide rods slide in opposite directions along the guide groove.

[0006] Optionally, a first spring is provided between the ring and the circular plate, and the circular plate is reset by the elastic force of the first spring. A second spring is provided between the slide groove and the L-shaped slide rod, and the L-shaped slide rod is reset by the elastic force of the second spring.

[0007] Optionally, the linear motor is equipped with a lifting device and a limiting device for lifting the wheel hub. The lifting device includes a push plate, a sliding frame, a sliding seat, and a pulley frame. The push plate is fixedly installed at the output end of the linear motor. The sliding frame is slidably installed on the surface of the linear motor. The sliding seat is slidably installed on the surface of the linear motor. The pulley frame is rotatably installed on the inner wall of the sliding seat. The push plate pushes the sliding frame to move upward. The upward movement of the sliding frame pushes the pulley frame to rotate upward. The upward movement of the pulley frame supports the bottom of the wheel hub.

[0008] Optionally, a short rod is fixedly mounted on the surface of the linear motor, a trapezoidal frame is slidably mounted on the surface of the limiting block, and an arc-shaped slider is slidably mounted on the surface of the limiting block. The short rod will squeeze the inclined surface of the trapezoidal frame, causing the trapezoidal frame to move upward. The upward movement of the trapezoidal frame will push the arc-shaped slider to move closer to the wheel hub. The arc-shaped slider will press against the wheel hub, making the wheel hub fit tightly against the fixed platform.

[0009] Optionally, a No. 3 spring is provided between the sliding frame and the linear motor, and the sliding frame is reset by the elastic force of the No. 3 spring. A No. 4 spring is provided between the sliding seat and the linear motor, and the sliding seat is reset by the elastic force of the No. 4 spring. A No. 5 spring is provided between the limiting block and the trapezoidal frame, and the trapezoidal frame is reset by the elastic force of the No. 5 spring. A No. 6 spring is provided between the limiting block and the arc-shaped slider, and the arc-shaped slider is reset by the elastic force of the No. 6 spring.

[0010] Optionally, the limiting device includes a U-shaped frame, a connecting rod, a limiting rod, and a trapezoidal slider. The U-shaped frame is slidably mounted on the surface of the sliding frame, the connecting rod is fixedly mounted on the top of the U-shaped frame, the limiting rod is slidably mounted on the top of the connecting rod, and the trapezoidal slider is slidably mounted on the surface of the sliding frame. The upward movement of the sliding frame drives the U-shaped frame to move upward, which in turn drives the connecting rod and the limiting rod to move upward, thereby blocking the wheel hub through the limiting rod.

[0011] Optionally, a trapezoidal seat is slidably mounted on the surface of the sliding frame, a sliding plate is slidably mounted on the inner wall of the sliding frame, and a trapezoidal plate is fixedly mounted on the bottom of the sliding plate. When the trapezoidal slider moves away from the connecting rod, it will release the limiting position on the connecting rod. The U-shaped frame, connecting rod and limiting rod are reset, so that the limiting rod can block the wheel hub again.

[0012] Optionally, a first return spring is provided between the U-shaped frame and the sliding frame, and the U-shaped frame is reset by the elastic force of the first return spring. A second return spring is provided between the trapezoidal slider and the sliding frame, and the trapezoidal slider is reset by the elastic force of the second return spring. A third return spring is provided between the sliding frame and the trapezoidal seat, and the trapezoidal seat is reset by the elastic force of the third return spring. A fourth return spring is provided between the sliding frame and the sliding plate, and the sliding plate is reset by the elastic force of the fourth return spring.

[0013] This invention provides a turning device and method for correcting runout on the end face of aluminum alloy wheel hubs. It has the following beneficial effects: This invention uses a ring and a circular plate to cover the inner ring of the wheel hub, exposing the flange end face. This prevents aluminum chips generated during machining from falling onto the inner ring of the wheel hub. The excessively high temperature of the chips would melt and adhere to the inner side of the wheel hub, forming hard aluminum lumps that would affect the stability of the wheel hub. The circular plate pushes the aluminum chips away from the inner wall of the ring to prevent them from accumulating on the inner wall of the ring and affecting subsequent processing. Two upper and lower L-shaped sliding rods slide in opposite directions along the guide groove to remove aluminum chips near the flange end face. This prevents aluminum chips from scratching the flange surface when repairing other wheel hubs, which would damage the flange surface, affect the installation of the flange and the vehicle, and pose a safety hazard.

[0014] This invention uses an upward-moving pulley bracket to support the bottom of the wheel hub, preventing it from slipping off the handle and falling to the ground when the wheel hub is removed from the mounting platform due to its weight. This prevents the wheel hub from being deformed and affecting its normal use. By providing auxiliary support to the bottom of the wheel hub during disassembly, the wheel hub is easier to remove and the replacement and installation are safer. The arc-shaped slider abuts against the wheel hub, ensuring a tight fit between the wheel hub and the mounting platform and preventing gaps that could cause the wheel hub to slip during maintenance. Positional deviations can affect actual data, leading to excessive or insufficient machining and affecting the accuracy of machining.

[0015] This invention uses a limiting rod to block the wheel hub, preventing it from slipping off the fixed platform when the arc-shaped slider moves away from the hub, causing damage and affecting normal use. The limiting rod prevents the wheel hub from accidentally falling, improving equipment safety. Simultaneously, the movement of the trapezoidal slider away from the connecting rod releases the limiting force on the connecting rod, allowing the first return spring to reset the U-shaped frame, connecting rod, and limiting rod, enabling the limiting rod to re-block the wheel hub without manual release. This makes operation more convenient and prevents the wheel hub from slipping off the fixed platform due to forgetting to release the limiting rod, thus avoiding damage. Attached Figure Description

[0018] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0019] Please see Figure 1 - Figure 5 One embodiment of the present invention is a turning device for correcting runout of the end face of an aluminum alloy wheel hub, comprising: a lathe 1, a turning device 2 disposed inside the lathe 1, a fixed table 3 disposed inside the lathe 1, a wheel hub 4 disposed on the surface of the fixed table 3, a linear motor 5 fixedly mounted on the surface of the fixed table 3, a limit block 6 fixedly mounted on the output end of the linear motor 5, a ring 7 fixedly mounted on the surface of the limit block 6, a circular plate 8 slidably mounted on the inner wall of the ring 7, a fixed plate 9 fixedly mounted on the surface of the linear motor 5, and a guide wheel 10 rotatably mounted on the surface of the limit block 6. A belt 11 is fixedly installed on the surface of the fixed plate 9. The end of the belt 11 away from the fixed plate 9 is fixedly installed on the surface of the circular plate 8. A sliding groove is opened on the surface of the circular plate 8. An L-shaped sliding rod 12 is slidably installed on the inner wall of the sliding groove. Four L-shaped sliding rods 12 are provided. A guide groove 13 is opened on the inner wall of the circular ring 7. The L-shaped sliding rod 12 is slidably connected to the guide groove 13 to remove aluminum chips near the flange end face. This is to prevent aluminum chips from scratching the flange surface when repairing other wheel hubs 4, which would damage the flange surface and affect the installation of the flange and the vehicle, posing a safety hazard.

[0020] A first spring is installed between the ring 7 and the circular plate 8. The circular plate 8 is reset by the elastic force of the first spring. A second spring is installed between the slide groove and the L-shaped slide rod 12. The L-shaped slide rod 12 is reset by the elastic force of the second spring.

[0021] The method of using the above-mentioned aluminum alloy wheel hub end face runout correction turning equipment includes the following steps: Step 1: Insert the scanned wheel hub 4 into the fixed platform 3, then the output of the linear motor 5 drives the limit block 6 to move closer to the wheel hub 4, and then the flange end face is corrected by the turning device 2 moving closer to the wheel hub 4. Step 2: At the same time, when the limiting block 6 moves towards the wheel hub 4, it drives the ring 7 and the circular plate 8 to move towards the wheel hub 4. The ring 7 and the circular plate 8 cover the inner ring of the wheel hub 4, exposing the flange end face. This prevents aluminum chips generated during the machining process from falling onto the inner ring of the wheel hub. The high-temperature aluminum chips melt and adhere to the inner surface of the wheel hub, forming hard aluminum blocks that affect the stability of the wheel hub. Step 3: At the same time, after the correction is completed, the linear motor 5 drives the limit block 6, the ring 7 and the circular plate 8 to move away from the wheel hub 4, and the belt 11 pulls the circular plate 8 to move closer to the limit block 6. The circular plate 8 pushes the aluminum chips away from the inner wall of the ring 7 to prevent the aluminum chips from accumulating on the inner wall of the ring 7 and affecting subsequent processing. Step 4: Simultaneously, the circular plate 8 moves towards the limit block 6, causing the L-shaped slide rod 12 to move towards the limit block 6. The L-shaped slide rod 12 moves towards the limit block 6 and slides along the guide groove 13, causing the upper and lower L-shaped slide rods 12 to slide in opposite directions along the guide groove 13, removing aluminum shavings near the flange end face. This prevents aluminum shavings from scratching the flange surface during wheel hub 4 repairs, which could damage the flange surface, affect the installation of the flange and the vehicle, and pose a safety hazard.

[0022] In this embodiment, during operation: the scanned wheel hub 4 is inserted into the fixed platform 3. Then, the output of the linear motor 5 drives the limiting block 6 to move closer to the wheel hub 4. Subsequently, the turning device 2 moves closer to the wheel hub 4 to correct the flange end face. Simultaneously, as the limiting block 6 moves closer to the wheel hub 4, it also drives the ring 7 and the circular plate 8 to move closer to the wheel hub 4. The ring 7 and the circular plate 8 cover the inner ring of the wheel hub 4, exposing the flange end face. This prevents aluminum chips generated during the turning process from falling onto the inner ring of the wheel hub. Excessive heat from these chips would cause them to melt and adhere to the inner side of the wheel hub, forming hard aluminum lumps that affect the stability of the wheel hub. After the correction is complete, the linear motor 5 drives the limiting block 6 and the ring 7... As the circular plate 8 moves away from the wheel hub 4, the belt 11 pulls the circular plate 8 towards the limit block 6. The circular plate 8 pushes aluminum chips away from the inner wall of the ring 7 to prevent them from accumulating and affecting subsequent processing. At the same time, the movement of the circular plate 8 towards the limit block 6 will also cause the L-shaped slide rod 12 to move towards the limit block 6. The L-shaped slide rod 12 will slide along the guide groove 13, causing the upper and lower L-shaped slide rods 12 to slide in opposite directions along the guide groove 13, removing aluminum chips near the flange end face. This prevents aluminum chips from scratching the flange surface when repairing other wheel hubs 4, which would damage the flange surface, affect the installation of the flange and the vehicle, and pose a safety hazard.

[0023] Please see Figure 1 - Figure 7Based on the above embodiments, in another embodiment of the present invention, the linear motor 5 is provided with a lifting device and a limiting device for lifting the wheel hub 4. The lifting device includes a push plate 141, a sliding frame 142, a sliding seat 143, and a pulley frame 144. The push plate 141 is fixedly installed at the output end of the linear motor 5, the sliding frame 142 is slidably installed on the surface of the linear motor 5, the sliding seat 143 is slidably installed on the surface of the linear motor 5, and the pulley frame 144 is rotatably installed on the inner wall of the sliding seat 143. This is to prevent the wheel hub 4 from being too heavy and falling to the ground when it is removed from the fixing platform 3, which would cause the wheel hub 4 to be deformed and affect its normal use. By providing auxiliary support to the bottom of the wheel hub 4 during the disassembly process, it is easier to disassemble the wheel hub 4 and make the replacement and installation safer.

[0024] A short rod 145 is fixedly mounted on the surface of the linear motor 5, a trapezoidal frame 146 is slidably mounted on the surface of the limit block 6, and an arc-shaped slider 147 is slidably mounted on the surface of the limit block 6 to prevent gaps in the middle from causing the wheel hub 4 to slide during maintenance. Positional deviation will affect the actual data, resulting in too much or too little machining, which will affect the accuracy of machining.

[0025] A No. 3 spring is installed between the sliding frame 142 and the linear motor 5. The sliding frame 142 is reset by the elastic force of the No. 3 spring. A No. 4 spring is installed between the sliding seat 143 and the linear motor 5. The sliding seat 143 is reset by the elastic force of the No. 4 spring. A No. 5 spring is installed between the limiting block 6 and the trapezoidal frame 146. The trapezoidal frame 146 is reset by the elastic force of the No. 5 spring. A No. 6 spring is installed between the limiting block 6 and the arc-shaped slider 147. The arc-shaped slider 147 is reset by the elastic force of the No. 6 spring.

[0026] In this embodiment, during operation: After maintenance, the output of the linear motor 5 moves away from the fixed platform 3, causing the push plate 141 to move away from the fixed platform 3. As the push plate 141 moves away from the fixed platform 3, it contacts the inclined surface of the sliding frame 142. The push plate 141 then pushes the sliding frame 142 upwards. This upward movement of the sliding frame 142 pushes the pulley frame 144 to rotate upwards. The upward movement of the pulley frame 144 provides support to the bottom of the wheel hub 4, preventing it from falling to the ground due to its weight when removing it from the fixed platform 3. This would cause the wheel hub 4 to be deformed and affect its normal use. By providing auxiliary support to the bottom of the wheel hub 4 during disassembly... The design facilitates the disassembly of the wheel hub 4, making replacement and installation safer. Simultaneously, when the limiting block 6 moves closer to the wheel hub 4, it causes the trapezoidal frame 146 to move closer to the wheel hub 4. As the trapezoidal frame 146 moves closer to the wheel hub 4, it contacts the short rod 145. The short rod 145 then presses against the inclined surface of the trapezoidal frame 146, causing the trapezoidal frame 146 to move upwards. This upward movement of the trapezoidal frame 146 pushes the arc-shaped slider 147 closer to the wheel hub 4. The arc-shaped slider 147 then presses against the wheel hub 4, ensuring a tight fit between the wheel hub 4 and the fixed platform 3. This prevents gaps that could cause the wheel hub 4 to slip during maintenance. Positional deviations would affect actual data, leading to excessive or insufficient machining and impacting machining accuracy.

[0027] The limiting device includes a U-shaped frame 151, a connecting rod 152, a limiting rod 153, and a trapezoidal slider 154. The U-shaped frame 151 is slidably mounted on the surface of the sliding frame 142, the connecting rod 152 is fixedly mounted on the top of the U-shaped frame 151, the limiting rod 153 is slidably mounted on the top of the connecting rod 152, and the trapezoidal slider 154 is slidably mounted on the surface of the sliding frame 142. This prevents the wheel hub 4 from losing its compression and sliding off the fixed platform 3 when the arc-shaped slider 147 moves away from the wheel hub 4, which would cause the surface of the wheel hub 4 to be bumped and deformed, affecting normal use.

[0028] A trapezoidal seat 155 is slidably mounted on the surface of the sliding frame 142, and a sliding plate 156 is slidably mounted on the inner wall of the sliding frame 142. A trapezoidal plate 157 is fixedly mounted on the bottom of the sliding plate 156. There is no need to manually release the limit, making the operation more convenient. This prevents the wheel hub 4 from slipping off the fixed platform 3 without being blocked by the limit rod 153, which would cause damage to the wheel hub 4.

[0029] A first return spring is provided between the U-shaped frame 151 and the sliding frame 142. The first return spring's own elastic force drives the U-shaped frame 151 to return to its original position. A second return spring is provided between the trapezoidal slider 154 and the sliding frame 142. The second return spring's own elastic force drives the trapezoidal slider 154 to return to its original position. A third return spring is provided between the sliding frame 142 and the trapezoidal seat 155. The third return spring's own elastic force drives the trapezoidal seat 155 to return to its original position. A fourth return spring is provided between the sliding frame 142 and the sliding plate 156. The fourth return spring's own elastic force drives the sliding plate 156 to return to its original position.

[0030] The upward movement of the sliding frame 142 causes the U-shaped frame 151 to move upward. This upward movement of the U-shaped frame 151, in turn, causes the connecting rod 152 and the limiting rod 153 to move upward. The limiting rod 153 blocks the wheel hub 4, preventing it from slipping off the fixed platform 3 when the arc-shaped slider 147 moves away from the wheel hub 4, thus avoiding damage to the surface of the wheel hub 4, deformation, and affecting normal use. The limiting rod 153 prevents the wheel hub 4 from slipping off the platform 3. To prevent accidental drops and improve equipment safety, when the wheel hub 4 needs to be removed, the connecting rod 152 is pushed downwards. As the connecting rod 152 moves downwards, it contacts the inclined surface of the trapezoidal slider 154. Once the connecting rod 152 disengages from the inclined surface of the trapezoidal slider 154, the elastic force of the second return spring will cause the trapezoidal slider 154 to return to its original position. Subsequently, the trapezoidal slider 154 will limit the connecting rod 152. The downward movement of the connecting rod 152 will cause the limiting rod 153 to move downwards, and the limiting rod 153 will disengage. After removing the obstruction from the wheel hub 4, the wheel hub 4 can be removed from above the fixed platform 3. Simultaneously, when a different wheel hub 4 is installed, the output of the linear motor 5 drives the push plate 141 to move closer to the fixed platform 3, which in turn pushes the trapezoidal plate 157 upwards. The upward movement of the trapezoidal plate 157 drives the sliding plate 156 upwards, which in turn pushes the trapezoidal seat 155 away from the connecting rod 152. The movement of the trapezoidal seat 155 away from the connecting rod 152 then drives the trapezoidal slider 15... Moving the trapezoidal slider 154 away from the connecting rod 152 will release the limit on the connecting rod 152. This will cause the elastic force of the first return spring to drive the U-shaped frame 151, the connecting rod 152, and the limit rod 153 to reset, allowing the limit rod 153 to block the wheel hub 4 again without manual release of the limit. This makes the operation more convenient and prevents the wheel hub 4 from slipping off the fixed platform 3 due to forgetting to release the limit, which could cause damage to the wheel hub 4.

[0031] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and application concept of this application, should be included within the scope of protection of this application.

The high-temperature aluminum chips melt and adhere to the inner surface of the wheel hub, forming a hard aluminum block, which affects the stability of the wheel hub. Step 3: At the same time, after the correction is completed, the linear motor (5) drives the limit block (6), the ring (7) and the circular plate (8) to move away from the wheel hub (4), and the belt (11) pulls the circular plate (8) to move closer to the limit block (6). The circular plate (8) pushes the aluminum chips away from the inner wall of the ring (7) to prevent the aluminum chips from accumulating on the inner wall of the ring (7) and affecting subsequent processing. Step 4: At the same time, the circular plate (8) moves towards the limit block (6), causing the L-shaped slide bar (12) to move towards the limit block (6). The L-shaped slide bar (12) moves towards the limit block (6) and slides along the guide groove (13), so that the upper and lower L-shaped slide bars (12) slide in opposite directions along the guide groove (13) to remove the aluminum chips near the flange end face, so as to prevent the aluminum chips from scratching the flange surface when repairing the wheel hub (4), causing damage to the flange surface, affecting the installation of the flange and the vehicle, and posing a safety hazard.
