[0002] In the process of manufacturing wheel hubs, an intelligent suspension conveying system is usually used to convey the wheel hubs. Different wheel hubs require different spraying processes and the number of spraying times also varies. After the spraying process of the wheel hub is completed, it is necessary to transfer it from the spraying line to the conveying line in time to avoid the continued circulation of the wheel hub and waste of costs. At the same time, the wheel hub that has not completed the spraying process continues to stay on the spraying line and continues the spraying process. At present, in the process of line transfer, a robot is mostly used to grab the line transfer and transport. The number of robots transported each time is limited, and continuous line transfer cannot be achieved. The line transfer efficiency is low. In order to solve the above problems, the present invention provides a continuous coating wheel hub line transfer lifting and conveying system. Summary of the invention

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0028] The present invention provides a continuous coating wheel hub rotating line lifting and conveying system, such as Figures 1 to 9 shown.

[0029] Embodiment 1: The present invention provides a continuous coating wheel hub rotating line lifting and conveying system, comprising a base frame 1, wherein the base frame 1 is mounted on the top side wall of the wall through a mounting plate fixedly connected thereto, and a section of the external coating line 2 and the conveying line 3 both pass through the base frame 1, and the coating line 2 and the conveying line 3 have opposite conveying directions inside the base frame 1, and a plurality of hooks 6 are fixedly mounted on the coating line 2 and the conveying line 3, and the opening direction of the hooks 6 on the coating line 2 and the conveying line 3 is opposite to the movement direction thereof (for example, the coating line 2 drives the hooks 6 thereon to move to the right, and the opening direction of the hooks 6 on the coating line 2 is toward the left), and the coating line 2 and the conveying line 3 both adopt an intelligent suspension conveying system (the intelligent suspension conveying system is a prior art, so the present invention will not elaborate on it), the coating line 2 can drive the wheel hub to move in the coating working area, and the conveying line 3 can transfer the coated wheel hub to the warehouse.

[0030] The hanging rod 4 is connected to the hooks 6 on the coating line 2 and the conveying line 3 respectively through the connecting head 5 fixedly connected thereon. The connecting hanging rod 4 is used to suspend the support wheel hub. An auxiliary support rod 7 is fixedly installed on the base frame 1. The hanging rod 4 is provided with a makeshift frame adapted to the auxiliary support rod 7. The shape of the makeshift frame is "C" shape. The auxiliary support rod 7 can assist in supporting the hanging rod 4 in the process of the coating line 2 driving the hanging rod 4 to move. When the hanging rod 4 needs to be transferred from the coating line 2 to the conveying line 3, the auxiliary support rod 7 is raised, and the hanging rod 4 rises along the inclined surface where the auxiliary support rod 7 is raised. The connecting head 5 on the hanging rod 4 is disengaged from the hook 6 on the coating line 2, and then is captured by the hook 6 on the conveying line 3, and is finally conveyed to the warehouse by the conveying line 3.

[0031] Embodiment 2: On the basis of embodiment 1, in order to ensure that the hanging rod 4 is transported more smoothly and lifted and lowered stably by the coating line 2 and the conveyor line 3, a roller 8 is arranged inside the clearance frame. During transportation, the roller 8 abuts against the auxiliary support rod 7. The upper side surface of the auxiliary support rod 7 is set as an inclined surface with a high middle and low sides. The circumferential surface of the roller 8 is matched with the upper side surface of the auxiliary support rod 7. The roller 8 and the auxiliary support rod 7 cooperate with each other to limit the hanging rod 4.

[0032] The auxiliary support rod 7 includes a first support rod 701 and a second support rod 702. The first support rod 701 and the second support rod 702 are fixedly installed on the base frame 1 through a connecting rod 703. A lifting rod 704 is provided between the first support rod 701 and the second support rod 702. One end of the lifting rod 704 is hinged to the first support rod 701. The lifting rod 704 is driven by an electric push rod 705 installed on the connecting rod 703. The outer shell of the electric push rod 705 is hinged to the connecting rod 703. The output rod of the electric push rod 705 is hinged to the lifting rod 704. When the output rod of the electric push rod 705 is extended, the lifting rod 704 remains in a horizontal state and is in the same straight line as the first support rod 701 and the second support rod 702. When the output rod of the electric push rod 705 is retracted, the lifting rod 704 rotates upward around the hinge point between it and the first support rod 701.

[0033] Driven by the coating line 2, the hanging rod 4 moves from the first support rod 701 to the second support rod 702. When it is necessary to transfer the hanging rod 4 from the coating line 2 to the conveyor line 3, the output rod of the electric push rod 705 retracts and the lifting rod 704 rotates upward, so that when the hanging rod 4 is driven by the coating line 2, the roller 8 rises along the inclined surface of the lifting rod 704 to lift the hanging rod 4. When the connecting head 5 rises to the height of the opening of the hook 6, the hanging rod 4 is disengaged from the hook 6 on the coating line 2. At this time, the hook 6 on the conveyor line 3 will be connected to the connecting head 5 and drive the connecting head 5 to move in the direction of the first support rod 701, and the roller 8 will descend along the inclined surface of the lifting rod 704 and be transported to the warehouse by the conveyor line 3.

[0034] In order to prevent the roller 8 from colliding with the lifting rod 704 during movement, causing the hanging rod 4 to shake and affecting the stability of the hanging rod 4, the roller 8 is set to be able to slide up and down in the clearance frame; A slider 10 is rotatably installed at one end of the roller 8, and a ring sleeve 11 is rotatably connected to the other end. The slider 10 is slidably installed in a slide groove 12 provided on the side wall of the yield frame. A first spring 13 is connected between the slider 10 and the groove wall at one end of the slide groove 12. When the roller 8 collides with the raised lifting rod 704 during movement, the first spring 13 can play a buffering role to prevent the hanging rod 4 from shaking.

[0035] Embodiment three: On the basis of the second embodiment, in order to ensure the stability of the hanging rod 4 when it is raised or lowered, a clamping portion is provided on the hanging rod 4, and a support frame 9 is provided on the base frame 1. When the hanging rod 4 rises, the clamping portion will extend from the inside of the hanging rod 4 under the action of the roller 8 and be clamped with the support frame 9, so that the hanging rod 4 can be raised and lowered stably. At the same time, the clamping portion can cooperate with the first spring 13, so that the roller 8 can better alleviate the impact force.

[0036] The clamping portion includes a stepped shaft 14, which is slidably installed in a stepped groove 15 provided on the hanging rod 4, and the diameter of the upper end of the stepped shaft 14 is smaller than the diameter of the lower end. A second spring 16 is connected between the stepped shaft 14 and the stepped groove 15. The lower end of the stepped shaft 14 is fixedly connected to the ring sleeve 11, and the upper end of the stepped shaft 14 is symmetrically fixedly connected to two spring plates 17. The upper ends of the two spring plates 17 are fixedly connected to a top cover 18, and a rotatable ball 19 is embedded in the upper side of the top cover 18.

[0037] Both ends of the lower opening of the support frame 9 are fixedly connected with support bars 21 adapted to the spring plate 17. One end of the support bar 21 close to the first support rod 701 is in a vertical state, and the other end is in a horizontal state, and the two ends of the support bar 21 have a smooth transition.

[0038] When the roller 8 is subjected to the pressing force of the lifting rod 704, the roller 8 will overcome the elastic force of the first spring 13 and the second spring 16 and move upward, so that the stepped shaft 14 will extend from the inside of the hanging rod 4 and be inserted into the inside of the support frame 9, pressing against the support frame 9. In the process of the hanging rod 4 constantly following the movement of the coating line 2, the roller 8 will gradually rise, so that the top cover 18 can gradually press against the inner wall of the support frame 9, and the two spring plates 17 will gradually begin to deform. The middle parts of the two spring plates 17 will bend in a direction away from each other and fit with the horizontal section of the support bar 21, and then can adapt to the support frame 9. When the connecting head 5 is disengaged from the hook 6 on the coating line 2, the hanging rod 4 can also remain stable. The spring plate 17 will press against the support bar 21 and the inner wall of the support frame 9 under the action of its own elastic force, so that the hanging rod 4 can be better maintained stable.

[0039] A push rod 20 is provided between the two spring plates 17, and the push rod 20 is fixedly mounted on the upper end surface of the stepped shaft 14, and is used to apply opposite pressing forces to the two spring plates 17, so that when the top cover 18 is not pressed against the inner wall of the support frame 9, the middle parts of the two spring plates 17 will also bend in directions away from each other, thereby ensuring that when the top cover 18 is pressed against the inner wall of the support frame 9, the middle parts of the spring plates 17 can stably bend in directions away from each other.

[0040] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
