[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figures 1 to 2As shown in the figure, an embodiment of the present invention provides a wheel roundness correction device for a power-assisted bicycle, including a processing table 1. A first rotating hole 11 is provided in the middle of the processing table 1. A first movable frame 2 is provided on one side above the first rotating hole 11. A second movable frame 23 is provided on the side of the first rotating hole 11 away from the first movable frame 2. A rotating component 21 is installed at the top of the side of the first movable frame 2 away from the second movable frame 23. A rotating sleeve 22 is rotatably connected to the top of the side of the first movable frame 2 near the second movable frame 23. A rotating sleeve 22 is also rotatably connected to the top of the side of the second movable frame 23 near the first movable frame 2. A wheel body 4 is provided between the first movable frame 2 and the second movable frame 23. Multiple sets of correction components of different sizes are provided below the wheel body 4. A switching component is rotatably connected inside the first rotating hole 11. The multiple sets of correction components are connected to the switching component. The switching component can automatically adjust the correction component of the corresponding size to the top of the processing table 1 according to the width of the wheel body 4.

[0035] The switching component includes a rotating block 31 rotatably connected inside the first rotating hole 11, and pushers 3 are provided at both ends of the rotating block 31. The correction component includes a lifting frame 35 provided at the end of the electric telescopic rod 311 away from the rotating block 31, and a correction ball 36 is provided inside the lifting frame 35. Conical columns 37 are provided on both sides above the correction ball 36.

[0036] During the production of electric bicycle wheels, metal is bent and shaped under the force of processing machinery. After the wheels are processed, their roundness is tested. Wheels with unqualified roundness will cause bumps when the electric bicycle is driven and will affect the stability of the tire. Therefore, when a wheel with unqualified roundness is detected, it needs to be corrected. At this time, the unqualified wheel body 4 is placed downward from above the first rotating hole 11. At this time, the wheel body 4 can drive the switching component. During the downward movement of the wheel body 4, it drives the push frame 3 on both sides. The push frame 3 drives the rotating block 31 to rotate. The size of the multiple correction components is arranged in order from small to large. Therefore, the larger the size of the wheel body 4, the longer the push frame 3 moves. The longer the push frame 3 moves, the larger the angle of rotation of the rotating block 31. The larger the rotation angle, the larger the size of the correction component will be and rotate it to the bottom of the wheel body 4. Thus, the corrective component can be switched according to the size of the wheel body 4. The larger the size of the correction component, the larger the size of the correction ball 36 and the conical column 37.

[0037] When the width of the wheel body 4 is the preset minimum size, the wheel body 4 matches the minimum size correction component. The pusher 3 will not be pushed, and the position of the correction component remains fixed. After the wheel body 4 moves between the first moving frame 2 and the second moving frame 23, it is fixed between the first moving frame 2 and the second moving frame 23 by two rotating sleeves 22. Then the correction component moves to the bottom position of the wheel body 4. At this time, the rotating component 21 drives the rotating sleeve 22 to rotate, which can make the wheel body 4 rotate slowly. While the wheel body 4 is rotating, the correction component corrects the wheel body 4. The correction ball 36 rolls inside the groove on the outside of the wheel body 4, which can correct the groove of the wheel body. During the correction process, the conical column 37 squeezes the deformed parts on both sides of the wheel body 4 to the center to reset, so that the metal ring of the wheel component 4 is corrected inside and outside at the same time. During the correction process, the correction component remains fixed. Therefore, when the wheel body 4 rotates, the deformed position will be squeezed by the correction component, so that its deformed part is adjusted. The wheel body 4 can be corrected after rotating multiple times.

[0038] When the width of the wheel body 4 is greater than the preset minimum size, the pusher 3 is pushed by the wheel body 4. At this time, the pusher 3 can drive multiple sets of correction components to rotate and make the correction components of the corresponding size rotate to the bottom of the wheel body 4. At this time, the wheel body 4 can be corrected by the correction ball 36 and the conical column 37 of the corresponding size. In this way, the correction size can be automatically adjusted when the wheel body 4 is corrected, without manual calibration. Moreover, the corresponding size adjustment does not require manual control of the size, which can prevent the wheel body 4 from deforming during the correction process due to adjustment errors.

[0039] like Figures 1 to 6 As shown, rotating blocks 31 are fixed with rotating columns 312 at both ends. A guide groove 313 is provided on the outer side of the rotating column 312. The two guide grooves 313 are symmetrically arranged about the vertical center line of the rotating block 31. A second rotating hole 34 is provided at the bottom of one side of the push frame 3. A protrusion 341 is fixed at the top of the second rotating hole 34. The second rotating hole 34 is fitted on the outside of the rotating column 312. The protrusion 341 is slidably connected to the inside of the guide groove 313. An electric telescopic rod 311 with the same number and position as the correction component is installed on the outer side of the rotating block 31. The end of the electric telescopic rod 311 away from the rotating block 31 is fixedly connected to the correction component.

[0040] When the wheel body 4 is placed between the rotating sleeves 22, the outer side of the wheel body 4 will contact the pushers 3 on both sides. The pushers 3 are pushed so that the second rotating hole 34 can slide outside the rotating column 312. At this time, the protrusion 341 will slide inside the guide groove 313. The protrusion 341 will be guided by the edge of the guide groove 313 to make the rotating column 312 rotate. The rotating column 312 drives the rotating block 31 to rotate. The rotating block 31 drives the correction component to rotate through the electric telescopic rod 311. At this time, the wheel body 4 drives the pushers 3 to move to both sides by a preset distance. The pushers 3 drive the protrusion 341 so that the guide groove 313 drives the rotating column 312 to rotate by a preset angle. At this time, the rotating column 312 drives the rotating block 31 so that the preset corresponding correction component can rotate to the bottom of the wheel body 4. The correction component can be pushed to the bottom of the wheel body 4 through the electric telescopic rod 311. Then the correction component can be pressed against the wheel body 4 and corrected when the wheel body 4 rotates.

[0041] like Figures 1 to 5 As shown, a push plate 32 is fixed to the top of the push frame 3 near the rotating block 31, and an arc plate 321 is fixed to the top of the push plate 32. The two sets of arc plates 321 are symmetrically arranged about the vertical center line of the rotating block 31.

[0042] When the wheel body 4 pushes the push frame 3 downward, an arc plate 321 is provided so that the wheel body 4 can easily drive the push frame 3. When the wheel body 4 moves downward, its edge contacts the arc plate 321. Under the action of the arc surface of the arc plate 321, the push plate 32 is driven to move. When the push plate 32 moves, it can drive the push frame 3 to move to both sides. The push plate 32 is used to extend the contact range between the push frame 3 and the wheel body 4. The push frame 3 can be driven to move within the length range of the push plate 32.

[0043] like Figures 1 to 5 As shown, a set of first sliding grooves 124 are provided on both sides of the first rotating hole 11. There are two first sliding grooves 124 in each set. The pusher 3 is slidably connected inside the first sliding groove 124. A second spring 33 is fixed on the side of the bottom of the pusher 3 away from the push plate 32. The other end of the second spring 33 is fixedly connected to the inner wall of the first sliding groove 124.

[0044] When the pusher 3 is pushed and moved, it will slide inside the first slide groove 124. At this time, the first slide groove 124 will play a limiting and guiding role for the pusher 3, so that the pusher 3 can maintain horizontal movement during the movement. At the same time, the second spring 33 can be squeezed when the pusher 3 moves on both sides. When the wheel body 4 is corrected and removed, the elastic force of the second spring 33 will push the pusher 3 to reset, which is convenient for the next correction.

[0045] like Figures 1 to 7 As shown, a pressure sensor is fixed between the electric telescopic rod 311 and the lifting frame 35, and the top of the calibration ball 36 can be pressed against the inside of the groove on the outside of the wheel.

[0046] When the calibration component is in use, it is first driven by the rotating block 31 to rotate to the corresponding position. Then, the electric telescopic rod 311 located above is activated to push the lifting frame 35 upward. At this time, the lifting frame 35 drives the calibration ball 36 to stick to the bottom end of the wheel body 4. After sticking, the pressure value of the pressure sensor increases. At this time, the operation of the electric telescopic rod 311 is stopped. Then, the wheel body 4 is driven to rotate and can be calibrated by the calibration ball 36. During the rotation, the calibration ball 36 rolls inside the groove on the outside of the wheel body 4, which can squeeze the protrusion of the wheel body 4 to deform it. This deformation is achieved by squeezing.

[0047] like Figures 1 to 8 As shown, the bottom ends of the two conical columns 37 can be pressed against the inner surface of the wheel, and the outer metal ring of the wheel can be locked by the correction ball 36 and the conical columns 37.

[0048] During the processing, the two sides of the wheel body 4 may deform, which will cause the outer side of the wheel body 4 to extend outward and affect the correction. Therefore, during the process of the correction ball 36 pressing the wheel body 4, the conical column 37 can limit the inner side of the wheel body 4. When the wheel body 4 rotates, the conical column 37 will roll with the wheel body 4. The conical column 37 can press the deformed parts on both sides of the wheel body 4 back to the center to restore them, thereby achieving further correction.

[0049] like Figures 1 to 8 As shown, sliding holes 351 are provided on both sides of the lifting frame 35. A connecting sleeve 371 is rotatably connected to the side of the conical column 37 away from the correction ball 36. Sliding rods 372 are fixed on both sides of the connecting sleeve 371. The sliding rods 372 are slidably connected inside the sliding holes 351. Connecting blocks 361 are rotatably connected to both sides of the correction ball 36. A second slider 373 is fixed at the bottom end of the connecting sleeve 371. A third groove 362 is provided at the top end of the connecting block 361. The second slider 373 is slidably connected inside the third groove 362.

[0050] Before and after use, the tapered column 37 will interfere with the wheel body 4. Therefore, the position of the tapered column 37 needs to be adjusted before and after use. Before use, the electric telescopic rod 311 pushes the lifting frame 35 closer to the bottom of the wheel body 4. At this time, the sliding rod 372 is at the highest point of the sliding hole 351. The sliding rod 372 drives the connecting sleeve 371 to position the tapered column 37 away from the correction ball 36. Then, the lifting frame 35 is fitted onto the outside of the bottom of the wheel body 4. At this time, the correction ball 36 will contact the wheel body 4. Under the thrust of the wheel body 4, the correction ball 36 will be pushed downward. When the correction ball 36 moves downward, it drives the connecting block 361 to descend. The connecting block 361 passes through... The second slider 373 pulls the connecting sleeve 371 downward, and the connecting sleeve 371 drives the tapered column 37 to move downward. During the movement, the sliding hole 351 guides the sliding rod 372, which allows the connecting sleeve 371 to move closer to the correction ball 36. The connecting sleeve 371 pushes the tapered column 37 to move above the correction ball 36. When the sliding rod 372 slides into the vertical path inside the sliding hole 351, the tapered column 37 can be placed in the area above the correction ball 36. At this time, the tapered column 37 will be attached to the inner side of the wheel body 4, which can complete the position adjustment of the tapered column 37. At the same time, the second slider 373 slides inside the third sliding groove 362 to adaptively adjust the connection position between the connecting sleeve 371 and the connecting block 361.

[0051] like Figures 1 to 8 As shown, a telescopic column 363 is fixed to the bottom end of the connecting block 361, and a third spring 364 is sleeved on the outside of the telescopic column 363. The top end of the third spring 364 is fixedly connected to the connecting block 361, and the bottom end of the third spring 364 is fixedly connected to the lifting frame 35.

[0052] During the downward movement of the connecting block 361, the third spring 364 is compressed. At the same time, the connecting block 361 pushes the telescopic column 363 into the interior of the lifting frame 35. When the correction ball 36 needs to be separated from the wheel body 4, the electric telescopic rod 311 is activated to pull the lifting frame 35 downward to reset. At this time, the correction ball 36 gradually loses the squeezing force. The elastic force of the third spring 364 pushes the connecting block 361 to reset. The connecting block 361 drives the connecting sleeve 371 to move upward. The slide rod 372 guides the connecting sleeve 371 to pull the conical column 37 to both sides to separate it from the top of the correction ball 36. Then the correction ball 36 can be separated from the wheel body 4. During the correction of the wheel body 4, the correction component is first made to fit tightly with the wheel body 4. Then the electric telescopic rod 311 is controlled to adjust to the position of the preset diameter of the wheel body 4. During the rotation of the wheel body 4, the deformation area of ​​the wheel body 4 can be gradually corrected to the position of the same preset diameter.

[0053] like Figures 1 to 3As shown, a moving block 123 is fixed at the bottom of the first moving frame 2 and the second moving frame 23. A moving groove 122 is opened between the first sliding grooves 124. The moving block 123 is slidably connected inside the moving groove 122. A threaded rod 121 is rotatably connected inside the two moving grooves 122. The outer sides of both ends of the threaded rod 121 are provided with opposite patterns. The threaded rod 121 is threadedly connected to the moving block 123. A first motor 12 is installed on one side of the processing table 1. The end of the rotating shaft of the first motor 12 is fixedly connected to the threaded rod 121.

[0054] When the wheel body 4 is installed inside the rotating sleeve 22, the first moving frame 2 and the second moving frame 23 are initially separated to the maximum distance. Then, the wheel body 4 is placed between the first moving frame 2 and the second moving frame 23. Then, the first motor 12 is started to drive the threaded rod 121. The threaded rod 121 drives the moving block 123 to slide inside the moving groove 122. The moving block 123 drives the first moving frame 2 and the second moving frame 23 to move closer. At this time, the rotating sleeve 22 can be driven to be sleeved on the outside of the wheel body 4 shaft. When the wheel body 4 needs to be removed, the first motor 12 can be started to rotate in the opposite direction. At this time, the first moving frame 2 and the second moving frame 23 move in opposite directions, which makes it convenient to install and remove the wheel body 4.

[0055] like Figures 1 to 10 As shown, the rotating sleeve 22 has an internal movable cavity 221. The movable cavity 221 has multiple guide holes 222 on the side near the fixed opening. A clamping block 24 is slidably connected inside the guide holes 222. A rotating frame 243 is rotatably connected inside the movable cavity 221. A first slider 242 is rotatably connected to the bottom end of the rotating frame 243 near the clamping block 24. A second groove 241 is provided at the top of the clamping block 24. The first slider 242 is slidably connected inside the second groove 241. A push post 223 is slidably connected to the middle of the rotating sleeve 22. One end of the push post 223 extends into the interior of the movable cavity 221. A first spring 244 is fixed to the end of the rotating frame 243 away from the clamping block 24. The other end of the first spring 244 is fixedly connected to the inner wall of the movable cavity 221.

[0056] After the axle of the wheel body 4 is inserted into the rotating sleeve 22, the axle pushes the push column 223, which in turn pushes the rotating frame 243 to rotate. As the rotating frame 243 rotates, it presses the clamping block 24 downward from the inside of the guide hole 222. At this time, the clamping block 24 can clamp the axle inside the rotating sleeve 22. The anti-slip texture on the bottom of the clamping block 24 can prevent slippage when the axle rotates. When the first moving frame 2 and the second moving frame 23 drive the rotating sleeve 22 to separate from the axle, the anti-slip texture does not affect the sliding of the axle. At the same time, the elastic force of the first spring 244 pushes the rotating frame 243 to reset, and the rotating frame 243 pulls the clamping block 24 back to its original position. During this process, the second sliding groove 241 and the first sliding block 242 are used to transmit the force of lifting and lowering the clamping block 24 and the rotating frame 243, which can realize the automatic clamping of the axle of the wheel body 4 inside the rotating sleeve 22.
