[0001] The invention relates to the technical field of motorcycle wheel hub cutting and positioning, in particular to a rough blank cutting and positioning device for motorcycle wheel hub processing. Background Art

[0002] As a key component connecting the vehicle to the ground, the manufacturing accuracy and quality of the motorcycle wheel hub are directly related to the safety, comfort and durability of the entire vehicle. In the production and processing of motorcycle wheels, rough cutting is one of the key steps in the wheel hub processing process. It not only determines the initial shape and dimensional accuracy of the wheel hub, but also directly affects the smooth progress of subsequent processing steps and the performance of the final product.

The front side of the bottom of the first scraper 16 is fixedly connected to one end of the first connecting member 18, and the other end of the first connecting member 18 is fixedly connected to the second scraper 17. The second scraper 17 is used to remove burrs on the inner side of the wheel hub. When the wheel hub is driven to rotate by the motor 13, the first scraper 16 and the second scraper 17 can fit the outer surface and the inner surface of the wheel hub, so as to efficiently remove the burrs. When batch processing is carried out, it can ensure that the burrs of each wheel hub are removed evenly and consistently, thereby improving the consistency of product quality.

The force storage spring 22 is used to drive the brush 24 to slide downward so that the brush 24 can adapt to the wheels of different sizes for fitting. When the wheel rotates, the bottom of the brush 24 can color the outer surface of the wheel, so that the color of the burr is different from that of the wheel body, making the burr more conspicuous, thereby improving the accuracy and efficiency of identifying the burr. After the burr is removed, the color contrast between the burr and the surrounding area is more distinct, so that the staff can more easily identify the thoroughness of the removal of the tiny burr.

[0039] refer to Figures 8 to 10 As shown, a rough blank cutting and positioning device for motorcycle wheel hub processing is provided, wherein a toggle member 3 is fixedly connected to the right side of the front end of the first scraper 16, and the first scraper 16 is used to drive the toggle member 3 to slide simultaneously, and the end of the toggle member 3 away from the first scraper 16 is inclined, and the end of the toggle member 3 away from the first scraper 16 is pressed and matched with a latch 31, and the toggle member 3 is used to squeeze the latch 31 to cause the latch 31 to slide upward, and the outer surface of the latch 31 is slidably connected to the right side of the connecting block 111, and the outer surface of the bottom of the latch 31 is fixedly sleeved with a tension spring 32, and the upper surface of the tension spring 32 is fixedly connected to the lower surface of the right side of the connecting block 111, and the tension spring 32 is used to The latch 31 is driven to reset and the bottom of the latch 31 is clamped on the upper surface of the connecting frame 113. The latch 31 is used to clamp the connecting frame 113. The outer surface of the rotating column 112 is symmetrically fixed with a second torsion spring 33. The outer sides of the second torsion springs 33 are fixedly connected to the inner side of the connecting frame 113. The second torsion springs 33 are used to drive the rotating column 112 to flip outward. When the first scraper 16 slides forward, it can indirectly drive the latch 31 to move upward, so that the second torsion spring 33 drives the first scraper 16 and the second scraper 17 to flip outward through the connecting block 111, so that the staff can clearly observe the stuck position and size and take corresponding measures.

[0040] refer to Fig.11 and Fig.12As shown, a rough blank cutting positioning device for motorcycle wheel hub processing is provided, wherein the outer surface of the front side of the rotating column 112 is fixedly connected to the second connecting member 4, the rotating column 112 is used to drive the second connecting member 4 to flip downward at the same time, the rear side of the left end of the second connecting member 4 is slidably connected to the limiting member 42, the outer surface of the limiting member 42 close to the second connecting member 4 is fixedly sleeved with a return spring 41, the side of the return spring 41 away from the limiting member 42 is fixedly connected to the rear side of the second connecting member 4, and the return spring 41 is used to drive the limiting member 42 to reset and move The outer surface of the fixing column 15 is slidably engaged with the limit plate 43, and the outer surface of the limit plate 43 is provided with a ring-shaped through-going groove. The groove provided on the outer surface of the limit plate 43 is engaged with the side of the limit member 42 away from the second connecting member 4. The limit member 42 is used to engage the limit plate 43 to prevent the limit plate 43 from rotating again. When the rotating column 112 is flipped outward, the limit member 42 is indirectly driven to be engaged with the outer surface of the limit plate 43, so that the limit plate 43 is fixed to the wheel hub, so that the staff can better remove the hard burrs.

[0041] The complete working principle and steps of the above embodiment are as follows:

[0042] refer to Figures 1 to 4 As shown, when the wheel hub processing equipment is in the initial state, the motor 13 is in the off state, and the pressure spring 19, the first torsion spring 110 and the linear spring 115 are all in a naturally relaxed state;

[0043] When the staff uses the equipment to remove burrs on the outer surface of the wheel hub, they first slide the support frame 12 to the right. When the support frame 12 moves to the right, it will slide into the inner side of the fixing member 11 and move the linear spring 115 to the extrusion state. At this time, the telescopic member 14 is adjusted to an appropriate length according to the size of the wheel hub, and the wheel hub is inserted into the outer surface of the fixing column 15. At this time, the linear spring 115 in the compressed state will drive the support frame 12 to move to the left, so that the left side of the support frame 12 fits the right side of the wheel hub, and when the wheel hub is placed on the outer surface of the fixing column 15, the outer surface of the fixing column 15 will fit the lower surface of the first scraper 16 and lift the first scraper 16 upward. When the first scraper 16 flips upward, it will drive the first torsion spring 110 to rotate to a power storage state through the fixing block 114. At this time, when the motor 13 is started, the output end of the motor 13 will drive the telescopic member 14 to rotate simultaneously, and when the telescopic member 14 rotates, it will drive the wheel hub to rotate simultaneously through the fixed column 15, and the first torsion spring 110 in the power storage state will drive the first scraper 16 to flip downward through the fixed block 114, and when the first scraper 16 flips downward, it will drive the second scraper 17 to flip downward simultaneously through the first connecting member 18, at this time, the lower surface of the rear side of the first scraper 16 will fit the outer surface of the wheel hub, and the lower surface of the rear side of the second scraper 17 will fit the lower surface of the inner side of the wheel hub, as the wheel hub rotates, the first scraper 16 and the second scraper 17 can efficiently remove burrs on the outer surface of the wheel hub, and can ensure that the burrs of each wheel hub are removed evenly and consistently during batch processing, thereby improving the consistency of product quality.

[0044] When hard burrs appear on the outer surface of the wheel hub, the burrs on the outer surface of the rotating wheel hub will prompt the first scraper 16 to slide forward. When the first scraper 16 slides forward, it will prompt the pressure spring 19 to move to a compressed state, and when the first scraper 16 moves forward, it will touch the trigger switch on the rear side of the connecting block 111. Since the trigger switch on the rear side of the connecting block 111 is electrically controlled and connected to the inner side of the motor 13, when the trigger switch on the rear side of the connecting block 111 is triggered, the output end of the motor 13 will stop rotating, thereby preventing the hard burrs from damaging the first scraper 16 and the second scraper 17. When the staff removes the hard burrs, the pressure spring 19 in a compressed state will drive the first scraper 16 to move backward. As the first scraper 16 moves backward, it will be separated from the contact with the trigger switch on the rear side of the connecting block 111. At this time, the motor 13 can drive the wheel hub to rotate again through the telescopic member 14 and the fixed column 15, and the first scraper 16 and the second scraper 17 will be re-attached to the outer surface of the wheel hub.

[0045] refer to Figures 5 to 7 As shown, when the wheel hub processing equipment is in the initial state, the force storage spring 22 is in a naturally relaxed state;

[0046] As the staff completes the placement of the wheel hub, the outer surface of the top of the wheel hub will fit against the bottom of the brush 24 and push the brush 24 upward. As the brush 24 is pushed upward, the storage column 23 will be moved to a compressed state, and the storage column 23 can drive the bottom of the brush 24 to fit tightly against the outer surface of the wheel hub. At this time, when the paint is put into the storage barrel 2, the paint inside the storage barrel 2 will be transported to the inside of the storage column 23 through the guide column 21. Since the inner side of the storage column 23 is symmetrically connected to the inner side of the guide column 21 through sliding, the paint inside the storage column 23 will be transported to the inside of the brush 24. As the wheel hub rotates, the paint inside the brush 24 will be smeared on the outer surface of the wheel hub, making the color of the burr different from that of the wheel hub body, making the burr more conspicuous, thereby improving the accuracy and efficiency of identifying the burr. After the burr is removed, the color contrast between the burr and the surrounding area is more distinct, allowing the staff to more easily identify tiny burrs and achieve a more thorough removal.

[0047] refer to Figures 8 to 10 As shown, when the wheel hub processing equipment is in the initial state, the bottom of the latch 31 is clamped on the upper surface of the connecting frame 113, the tension spring 32 is in a naturally relaxed state, and the second torsion spring 33 is in a force storage state;

[0048] When the first scraper 16 touches the hard burr, the first scraper 16 will drive the toggle member 3 to move forward at the same time. Since the front side of the toggle member 3 is inclined, the toggle member 3 will squeeze the outer surface of the latch 31 when it moves forward and drive the latch 31 to move upward. As the latch 31 moves upward on the left side of the connecting block 111, the tension spring 32 will be moved to a compressed state, and the latch 31 will also be disengaged from the bottom of the latch 31 from the upper surface of the connecting frame 113 when it moves upward. At this time, the second torsion spring 33 in the power storage state will rotate through the rotating column 112 drives the connecting block 111 to flip clockwise, and when the connecting block 111 flips clockwise, it will drive the first scraper 16 to flip at the same time through the fixed block 114, and when the first scraper 16 flips clockwise, it will also drive the second scraper 17 to flip at the same time. At this time, the first scraper 16 and the second scraper 17 can be separated from the fit on the outer surface of the wheel hub, and the staff can clearly observe the position and size of the jam and take corresponding measures. In addition, when the first scraper 16 and the second scraper 17 are turned outward, defects on the wheel hub surface caused by forced burr removal can be avoided.

[0049] As the staff removes the burrs, the connecting block 111 will be able to flip counterclockwise, and the flipping of the connecting block 111 counterclockwise can drive the latch 31 to flip at the same time, and the bottom of the latch 31 will be re-engaged with the outer surface of the top of the connecting frame 113 when the latch 31 flips counterclockwise, and the connecting block 111 will drive the first scraper 16 to flip at the same time through the fixed block 114, and the first scraper 16 can drive the second scraper 17 to flip counterclockwise at the same time, so that the first scraper 16 and the second scraper 17 are re-attached to the outer surface of the wheel hub, and the connecting block 111 drives the rotating column 112 to flip at the same time, and the second torsion spring 33 symmetrically fixed on the outer surface of the rotating column 112 returns to the stored force state.

[0050] refer to Fig.11 and Fig.12 As shown, when the wheel hub processing equipment is in the initial state, the return spring 41 is in a naturally relaxed state, and the rear side of the limiting member 42 has not yet been engaged with the groove on the outer surface of the limiting plate 43;

[0051] As the rotating column 112 rotates counterclockwise, the second connecting member 4 fixedly connected to the outer surface of the rotating column 112 will be driven to rotate at the same time, and the return spring 41 will drive the limit member 42 to flip at the same time when it rotates counterclockwise. At this time, the limit member 42 will be stuck in the groove on the outer surface of the limit plate 43 when it flips counterclockwise, and the rear side of the limit member 42 will be attached to the limit plate 43, which will move the return spring 41 to a compressed state. When the limit plate 43 is stuck, the fixed column 15 slidingly connected to the inner side of the limit plate 43 will be stuck at the same time, and the fixed column 15 can drive the wheel hub to be stuck, thereby preventing the wheel hub from rotating. At this time, the staff can better remove the hard burrs, and the stationary wheel hub can improve the stability of the operation, and can also avoid unnecessary scratches and damage to the wheel hub when removing the burrs.

[0052] When the staff has finished removing the burrs, the rotating column 112 can be rotated clockwise. As the rotating column 112 rotates, the limiting member 42 can be driven to rotate at the same time through the second connecting member 4, causing the rear side of the limiting member 42 to be disengaged from the clamping connection on the outer surface of the limiting plate 43, and the return spring 41 in the compressed state can drive the limiting member 42 to return to the initial state.

[0053] Although the present disclosure has been shown and described with reference to specific exemplary embodiments of the present disclosure, it should be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents.
