[0039] Please see Figures 1 to 3This embodiment proposes a grinding device for grinding a front fork 100, which includes a grinding part 1 and a driving part 2. The grinding part 1 has a grinding head that abuts against the front fork 100. The grinding head is made of a flexible material and the grinding part 1 is used to grind the front fork 100. The driving part 2 has a driving end 21 that moves with multiple degrees of freedom. The grinding part 1 is disposed on the driving end 21 so that the grinding head moves along different curved surfaces of the front fork 100.
[0040] Understandably, during the grinding process, the drive unit 2 can drive the grinding head to move along different curved surfaces of the fork 100. Since the grinding head is made of a flexible material, it can adapt to changes in the curved surface during the grinding process to ensure that the grinding head can contact different positions of the fork 100 and to ensure the contact area between the grinding head and the fork 100, thereby improving the grinding rate of the fork 100. The grinding rate refers to the percentage of the grinding area that occupies the entire surface of the fork 100.
[0041] The drive unit 2 is preferably a multi-axis robot as in the prior art. The end effector of the multi-axis robot, which serves as the drive end 21 of the drive unit 2, has multiple free ends that can move, thereby adapting to different curved surfaces of the fork 100 and ensuring grinding quality.
[0042] Furthermore, the grinding section 1 also includes a rotating member 11 and a grinding base 12. The rotating member 11 has a rotating end that rotates around its own axis, and the rotating end is connected to the grinding base 12. The grinding head is detachably mounted on the grinding base 12. It is understood that the rotating member 11 is preferably a pneumatic motor as in the prior art. The shaft of the pneumatic motor serves as the rotating end of the rotating member 11 and is connected to the grinding base 12. During the grinding process, the pneumatic motor can drive the grinding base 12 to rotate, thereby driving the grinding head to rotate, so as to grind the fork 100. The grinding head is detachably mounted on the grinding base 12 to facilitate replacement of the grinding head, thereby ensuring grinding quality. The detachable method is preferably a snap-fit or similar method as in the prior art, which will not be elaborated here.
[0043] Furthermore, the grinding seat 12 is disc-shaped and coaxially arranged with the rotating end. This arrangement ensures that the grinding seat 12 does not shift during rotation, thereby guaranteeing the grinding quality of the fork 100.
[0044] In this embodiment, the grinding head is preferably a grinding sponge. It is understood that a grinding sponge is a flexible material composed of a sponge substrate and grinding particles, possessing high elasticity. During the grinding process, with the rotation of the rotating component 11 and the movement of the driving part 2, the grinding sponge can adapt well to the curvature of different parts of the fork 100, thereby providing a uniform grinding effect to ensure the grinding rate of the fork 100. In some other feasible embodiments, the grinding head can also be a grinding structure such as a rubber-based grinding tool in the prior art, which will not be elaborated here.
[0045] The grinding head is hemispherical. This hemispherical shape allows for a better fit to the concave and convex surfaces of the fork 100, further ensuring grinding quality. Furthermore, compared to a flat grinding head, which suffers from stress concentration at the edges leading to scratches on the fork 100 surface or rapid wear, the hemispherical grinding head distributes internal stress evenly along the curved surface under pressure, thus preventing scratches on the fork 100 surface and ensuring the grinding head's lifespan.
[0046] In this embodiment, the grinding device further includes a clamping part 3 and a rotating part 4. The clamping part 3 is used to clamp the front fork 100; the rotating part 4 is connected to the clamping part 3 and is used to control the front fork 100 to rotate at a preset angle so that the front fork 100 has multiple grinding positions. It can be understood that under the action of the rotating part 4, the front fork 100 can be controlled to rotate at a preset angle so that the front fork 100 rotates to different grinding positions. After multiple rotations, the front fork 100 can achieve 360° rotation. With the cooperation of the rotating part 4 and the driving part 2, the grinding rate of the front fork 100 can be improved.
[0047] Optionally, the preset angle is 30°, 40°, 45°, or 60°. It is understood that after multiple rotations, the fork 100 can rotate one full turn, ensuring the thorough grinding of the fork 100. In this embodiment, the preset angle is preferably 45°, meaning that the fork 100 can achieve a 360° rotation after 8 rotations.
[0048] The clamping part 3 is preferably a three-jaw chuck, which can clamp the upper tube 110 of the fork 100. The rotating part 4 is preferably a hollow rotary motor, which has a hollow rotor as the rotating end. The hollow rotor is coaxially arranged with the upper tube 110 clamped in the three-jaw chuck to avoid deviation of the fork 100 during rotation and further ensure the uniformity of grinding at each position of the fork 100.
[0049] In this embodiment, a clamping part 3 and a rotating part 4 constitute a set of clamping components, and the grinding device is provided with at least two sets of clamping components. The grinding device also includes a platform 5 and a base 6. The platform 5 is divided into a grinding area and a loading / unloading area, and the drive unit is located in the grinding area. The base 6 is rotatably mounted on the platform 5, and all clamping components are located on the base 6. The fork 100 clamped by the clamping components can extend to the outside of the base 6. It can be understood that the operator installs the fork 100 onto the clamping part 3 in the loading / unloading area, and then rotates the base 6 by rotating a rotating structure such as a rotating motor to move the fork 100 to the grinding area. Under the action of the drive unit and the grinding head, the fork 100 can begin to be ground. After grinding, the base 6 is rotated again to rotate the fork 100 to the loading / unloading area to complete the unloading. The whole process can reduce the loading / unloading time, thereby improving the grinding efficiency.
[0050] Furthermore, baffles 7 are provided between each clamping component, and the baffles 7 are fixed to the base 6. It is understood that debris will be generated during the grinding process, and the baffles 7 can block the debris in the grinding area, thereby ensuring the cleanliness of the loading and unloading area.
[0051] In addition, the base 6 is preferably elongated, the rotating motor is connected to the middle of the base 6, and when the fork 100 is installed in the clamping part 3, it can extend to the outside of the base 6, thereby preventing debris from falling onto the base 6 and further ensuring the cleanliness of the loading and unloading area.
[0052] In this embodiment, the grinding device also includes a collection chamber 8, which is funnel-shaped and disposed in the grinding area, below the base 6. The collection chamber 8 is used to collect the debris that falls off after grinding. It is understood that during the grinding process, the debris falling off the fork 100 can be collected by the collection chamber, thereby ensuring the cleanliness of the grinding area.
[0053] In this embodiment, the grinding device further includes a lifting part 9, which is disposed on the platform 5 and located in the loading and unloading area. The lifting part 9 is used to apply a lifting force to the fork 100 to be clamped by the clamping part 3, so that the clamping part 3 can stably clamp the fork 100. It can be understood that when the fork 100 is installed in the loading and unloading area, the lifting part 9 can apply a lifting force to the fork 100, thereby enabling the fork 100 to be in a stable state during installation. This avoids uneven weight distribution or irregular shape of the fork 100, which could lead to instability during installation. It also ensures the consistency of different forks 100 when clamped, thus helping to ensure the consistency of different forks 100 during the grinding process.
[0054] For example, the lifting part 9 includes a lifting cylinder 91 and a lifting rod 92. The lifting cylinder 91 is disposed on the platform 5, and the lifting rod 92 is horizontally disposed at the piston rod end of the lifting cylinder 91. The lifting cylinder 91 is used to lift the lifting rod 92 to a preset height. It can be understood that under the action of the lifting cylinder 91, the lifting rod 92 can be moved to a preset height to abut against the two lower tubes 120 of the front fork 100, thereby enabling the front fork 100 to be stably installed on the clamping part 3, and also ensuring the consistency of different front forks 100 during the installation process.
[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
