Description

Technical Field

[0001] The present invention relates to the technical field of intelligent conveying of automobile wheel hubs, and in particular to intelligent automatic side unhooking and conveying equipment for automobile wheel hubs. Background Art

[0002] After the spokes and rims are extruded and assembled, they need to be transported to welding, inspection, and painting stations. The condition of the hub determines whether it can be directly processed on the conveying equipment without removal. The condition of the hub also determines whether it is convenient and labor-saving for workers to remove and install the hub on the conveyor line. In the existing technology, the lifting device used is often an S-shaped hook. When removing the hub, it is necessary to lift it upward to unhook the two and then pull it out horizontally. During this process, the S-shaped hook will also shake, causing the worker to spend a little more physical effort in the removal process. Long-term assembly line production operations will make workers overly tired. In addition, the angle of the hub is not constant each time it is taken, causing the worker to first adjust the hub to face the worker and then remove the hub. This process also consumes a lot of physical effort. And because of this, it is impossible to set up a robot to automatically remove the wheel hub. Instead, the wheel hub needs to be positioned by the equipment before it can be picked up by the robot. Therefore, it is necessary to design an intelligent automatic side unhooking conveying equipment for automobile wheel hubs, which can save workers from removing the wheel hubs and save workers' physical strength. The angle of each pick-up is constant, which further saves physical strength. It can also be used for a robot to clamp and remove the wheel hub. Summary of the Invention

Furthermore, when a worker needs to remove the wheel hub, the jacking mechanism can be used to lift the mounting frame, causing the wheel hub to automatically rotate and move to a position facing the worker. In this position, the locking mechanism automatically unlocks, allowing the worker to simply pull out the wheel hub horizontally, maintaining a constant angle each time. This saves the worker considerable physical effort, and allows the wheel hub to be removed using a robotic arm.

[0015] After the wheel is removed, the angle limiter automatically locks the arm, eliminating the need for a lifting mechanism when the wheel is subsequently installed. After installation, the wheel automatically pushes the unlocking mechanism, unlocking the angle limiter and allowing the wheel to rotate downward to the center position. This intelligent automatic side-unhooking conveying device for automotive wheels now offers a new level of flexibility, enabling flipping and automatic unhooking compared to traditional conveyor lines, making it easier for workers or robots to remove the wheel. It represents an intelligent wheel suspension conveying system. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Embodiment: The present invention provides an intelligent automatic side unhooking conveying device for automobile wheel hubs, such as Figure 1-9As shown, it includes a track 1, a conveyor chain 2 and multiple hangers, each hanger includes a mounting frame 3, a guide slide 4, a bent arm 5 and a hinged rod 6. The conveyor chain 2 can be slidably installed in the track 1, and the track 1 is pushed to slide in the conveyor chain 2 by the moving device. The guide slide 4 can be rotatably installed on the rotating shaft 2a of the track 1, and the mounting frame 3 can be vertically slidably installed on the guide slide 4. The middle part of the bent arm 5 is hinged to the middle part of the bottom end of the mounting frame 3, one end of the hinged rod 6 is hinged to the guide slide 4, and the other end of the hinged rod 6 is hinged to the end of the bent arm 5 at the top. The other end of the bent arm 5 is fixedly provided with a seat 9 for the wheel hub 10 to be clamped, and the seat 9 is fixedly provided with a locking mechanism 7 for locking the wheel hub 10. An extension arm 3d is provided on the mounting frame 3, and a lifting mechanism 8 for lifting the mounting frame 3 upward is provided in the production process. When the wheel hub 10 needs to be installed, the extension arm 3d is first lifted upward by the working end of the lifting mechanism 8, so that the bending arm 5 is rotated to Figure 2 In the state shown, the wheel hub 10 can be clamped into the clamping seat 9. After the clamping is completed, the working end of the lifting mechanism 8 is retracted downward, and the wheel hub 10 is locked by the locking mechanism 7 during the downward rotation process. Figure 1 The status shown.

[0029] When the wheel hub 10 needs to be removed in each production process, Figure 1 Moving in the direction of the arrow shown will convert Figure 2 The state shown. Then follow Figure 2 Remove the hub 10 in the direction of the arrow shown.

[0030] The above method ensures that the wheel hub 10 can be perpendicular to the side when it is picked up. When picking it up, it only needs to be pulled horizontally to separate it from the lifting device. The entire picking process is simple, which can save workers' physical strength. It only requires one action and the picking speed is relatively fast. Compared with traditional lifting devices, it does not need to move the wheel hub 10 upward to unhook it from the lifting device before picking it up.

[0031] During transportation, the wheel hub 10 can be positioned below the mounting bracket 3, ensuring its center of gravity is oriented vertically downward during movement. While the right side of the sling also has some structure, its overall weight can be reduced by adding a counterweight on the left side. It should be noted that while each wheel hub 10 has a different weight, the slings used are uniform, making it impossible to change the counterweights of all slings after replacing a specific wheel hub 10.

[0032] Among them, if the above method is used, the lifting mechanism 8 needs to be lifted upward each time the wheel hub 10 is installed. However, the movement of the conveyor chain 2 can only take into account the time required for the production process. If a long wait is required to install the wheel hub 10, a long waiting time is required. In order to improve the production process, an angle limiting mechanism 11 is also included. The angle limiting mechanism 11 includes a clamping block 11a and an elastic extrapolation mechanism. The clamping block 11a can be installed on the extension arm 3d in a horizontally slidable manner. The extension arm 3d is provided with a square sliding hole 3e for the clamping block 11a to slide outward. When the axis of the wheel hub 10 rotates to a horizontal state, the elastic extrapolation mechanism pushes the clamping block 11a to contact the side of the bent arm 5. The elastic extrapolation mechanism is fixedly installed in the extension arm 3d. When the axis of the hub 10 is not rotated to a horizontal state, the arm 5 will cover the block 11a, so that the block 11a cannot be ejected, ensuring that the arm 5 can rotate. Once the axis of the hub 10 is rotated to a horizontal state, the block 11a that is no longer blocked will be pushed out by the elastic push mechanism, restraining the arm 5, so that the arm 5 cannot rotate downward, and the arm 5 will be in a state of rotation. Figure 2 When subsequently loading the wheel hub 10, the worker can directly insert the wheel hub 10 horizontally without the need for the jacking mechanism 8 to push it upward, thus saving the time required for loading the wheel hub 10.

[0033] The elastic outward pushing mechanism includes a hinged rod 11b, a guide post 11c and a spring 11d. The guide post 11c is slidably mounted on the extension arm 3d. One end of the hinged rod 11b is hinged to the clamping block 11a, and the other end of the hinged rod 11b is hinged to one end of the guide post 11c. The spring 11d is used to provide an elastic force for the guide post 11c to move closer to the clamping block 11a. Since the clamping block 11a is blocked by the bent arm 5, the clamping block 11a cannot be pushed outward. Once the bent arm 5 rotates to Figure 2 In the state shown, the clamping block 11a will pop out quickly, thereby limiting the bending arm 5.

[0034] After the wheel hub 10 is installed, how to release the locking block 11a from locking the bending arm 5, and the whole process is convenient. To this end, a release mechanism 12 is also included. The release mechanism 12 is used to automatically release the angle lock of the bending arm 5 when the wheel hub 10 is installed. The release mechanism 12 includes a connecting rod 12a, a second guide post 12b, and a contact plate 12c. The second guide post 12b can be mounted on the mounting frame 3 for horizontal sliding. The contact plate 12c is fixedly mounted on one end of the second guide post 12b. The connecting rod 12a is connected to the second guide post 12b and the first guide post 11c. When the wheel hub 10 is installed on the clamping seat 9, the end of the wheel hub 10 contacts the contact plate 12c, and the block 11a is retracted into the extension arm 3d. When the wheel hub 10 is installed on the holder 9, it pushes the contact plate 12c toward the mounting frame 3. During this process, the second guide post 12b pulls the first guide post 11c via the connecting rod 12a, which in turn pulls the first clamping block 11a into the extension arm 3d. Once installation is complete, the first clamping block 11a is completely retracted into the extension arm 3d. Unencumbered, the curved arm 5 is able to rotate downward under the weight of the mounting frame 3 and the tension of the hinged rod 6.

[0035] In order to automatically release the wheel hub 10 when rotating downward and automatically lock the wheel hub 10 when rotating upward, the locking mechanism 7 includes an arc-shaped baffle 7a, a displacement shaft 7b, a second spring 7c, a second clamping block 7d and an inner pulling mechanism 7e. The arc-shaped baffle 7a is fixedly mounted on the extension arm 3d. The axis of the arc-shaped baffle 7a is coaxially arranged with the rotation axis of the bent arm 5. A clamping tube 9a is provided on the clamping seat 9. The displacement shaft 7b is inserted into the clamping tube 9a. One end of the displacement shaft 7b is an arc-shaped structure and contacts the outer edge of the arc-shaped baffle 7a. Spring 2 (7c) applies an elastic force to the displacement shaft 7b, pushing it toward the arc-shaped baffle 7a. A contraction notch (7a1) is defined at the top of the arc-shaped baffle 7a. The other end of the displacement shaft 7b is tapered. The clamping tube (9a) includes a guide hole for the second clamping block (7d) to slide through. An internal pull mechanism (7e) is fixedly mounted within the clamping tube (9a) and is used to pull the two second clamping blocks (7d) inward. When the axis of the displacement shaft 7b rotates horizontally, the end of the displacement shaft 7b is inserted into the contraction notch (7a1), and the end of the second clamping block (7d) is retracted into the clamping tube (9a). Once the second clamping block (7d) is retracted into the clamping tube (9a), the wheel hub (10) and the clamping tube (9a) can be engaged by pushing horizontally. When fully inserted, one side of the wheel hub (10) is coplanar with one side of the second clamping block (7d). During the subsequent downward rotation of the holder 9, the end of the displacement shaft 7b will be pushed outward by the shrinkage notch 7a1, and the inclined surface of the displacement shaft 7b will push the second clamping block 7d out of the inside of the clamping tube 9a, so that the second clamping block 7d is locked to the wheel hub 10.

[0036] When the end of the displacement shaft 7b is away from the second clamping block 7d, the second clamping block 7d is pulled inward by the inner pulling mechanism 7e, so that the second clamping block 7d can be received into the clamping tube 9a.

[0037] A retaining ring is provided on the displacement shaft 7 b , and the retaining ring is used to contact the second spring 7 c , one end of the second spring 7 c contacts the retaining ring, and the other end contacts the clamping seat 9 .

[0038] The inward-pulling mechanism 7e comprises a hinged rod 7e1, a sliding post 7e2, a spring 7e3, and a fixed end cap 7e5. One end of the hinged rod 7e1 is hinged to the second clamping block 7d, while the other end is hinged to the leading end of the sliding post 7e2. A limiting circular plate 7e4 is provided at the trailing end of the sliding post 7e2. The fixed end cap 7e5 is fixedly mounted on the clamping tube 9a. The sliding post 7e2 and the fixed end cap 7e5 are slidably connected. The spring 7e3 provides an elastic force to pull the sliding post 7e2 away from the displacement axis 7b. The elastic force of the spring 7e3 causes the hinged rod 7e1 to pull the second clamping block 7d inward. The elastic force of the spring 7e3 does not need to be high; it only needs to be sufficient to pull the second clamping block 7d inward.

[0039] The holder 9 also includes a baffle 9b and multiple circumferentially mounted posts 9c. The clamping tube 9a is fixedly mounted on the baffle 9b, and a central portion of the baffle 9b includes a clearance hole for the displacement shaft 7b to pass through. The baffles 9b limit the final position of the hub 10, while the posts 9c prevent the hub 10 from rotating after being engaged with the clamping tube 9a.

[0040] The mounting frame 3 includes a frame body 3a and two guide posts 3b. The guide slide 4 includes a guide plate 4a and a rotating plate 4b fixedly connected to the guide plate 4a. The rotating plate 4b is rotatably connected to the rotating shaft 2a. The two guide posts 3b are slidably connected to the guide plates 4a. The frame body 3a is fixedly mounted on the bottom of the two guide posts 3b, and a limiting circular plate 2c is fixedly mounted on the top of each guide post 3b. The frame body 3a is used for mounting other mechanisms. The bottom of the frame body 3a is provided with a rotating shaft for the bending arm 5 to rotate. When the frame body 3a is lifted upward, the guide posts 3b will slide vertically on the guide plates 4a. When the frame body 3a moves freely downward to its final position, the limiting circular plate 2c will limit the final position of the guide plates 4a.

[0041] The lifting mechanism 8 comprises a vertical pusher 8a and a riser 8b fixedly provided on the upper portion, wherein the vertical pusher 8a is used for vertically lifting the riser 8b upwards. By controlling the vertical pusher 8a to work, the vertical pusher 8a will lift the riser 8b upwards so that the extension arm 3d can be vertically pushed.

[0042] The frame 3a is fixedly provided with a counterweight 13. By providing the counterweight 13, the weight on both sides of the sling can be evenly distributed.

[0043] When the worker needs to remove the wheel hub 10, he lifts it upwards through the vertical pusher 8a, and the arm 5 is pulled and rotated by the mounting frame 3 and the hinge rod 6, and the wheel hub 10 will be removed from the wheel hub 10. Figure 1 Rotate to Figure 2 At this time, the angle limiting mechanism 11 locks the bending arm 5, and the locking mechanism 7 is unlocked, and the worker can remove the wheel hub 10.

[0044] When the worker needs to install the hub 10 on the lifting device, he pushes the hub 10 onto the clamping tube 9a. When the clamping tube 9a is pushed until it fits the baffle 9b, the unlocking mechanism 12 pulls the angle limit mechanism 11 to unlock the bending arm 5. The hub 10 can then rotate downward. At the beginning of the downward rotation, the displacement shaft 7b is pushed outward by the movable arc baffle 7a, and the locking mechanism 7 locks the hub 10.

[0045] This intelligent automatic side-unhooking conveying device for automobile wheels allows the wheel hub 10 to be vertically positioned at the center of the sling during transportation, ensuring a stable center of gravity and preventing wear and damage to the conveyor chain 2. When a worker needs to remove the wheel hub 10, the jacking mechanism 8 can lift the mounting frame 3, causing the wheel hub 10 to automatically rotate 90 degrees and move to a position facing the worker. In this position, the locking mechanism 7 automatically unlocks, allowing the worker to simply pull out the wheel hub 10 horizontally, maintaining a constant angle each time. This saves the worker considerable physical effort, and allows the wheel hub 10 to be removed using a robotic arm.

[0046] After the wheel hub 10 is taken out, the angle limiting mechanism 11 automatically locks the bending arm 5. When the wheel hub 10 is subsequently installed, there is no need to use the jacking mechanism 8. After installation, the wheel hub 10 can automatically push the unlocking mechanism 12 to unlock the angle limiting mechanism 11, so that the wheel hub 10 can rotate downward to the center position.

[0047] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
