Description

Technical Field

[0001] The invention relates to the technical field of hub body processing, and in particular to an automatic flipping and positioning device for hub surface processing. Background Art

[0002] The surface processing of the wheel hub body refers to a series of surface treatment processes performed on the wheel hub body to improve its appearance, corrosion resistance, wear resistance and overall performance. This process usually includes the following steps: first, the wheel hub body is polished and deburred to ensure a smooth and flawless surface; then it is cleaned to remove oil and impurities; then surface treatments such as electroplating, spraying, anodizing, etc. are performed, which can give the wheel hub body different colors and glosses while improving its corrosion resistance and wear resistance; finally, protective treatments are performed, such as coating with protective paint, to further protect the surface of the wheel hub body and extend its service life. The surface processing of the wheel hub body not only improves the appearance of the product, but also enhances its performance.

[0003] At present, there is a common technical bottleneck in the process of processing the surface of the hub body, that is, it is necessary to use a complex manipulator structure to realize the flipping operation of the hub body. This step not only increases the complexity and manufacturing cost of the equipment, but also during the flipping process, the hub body is often easy to deviate from the original transmission track, resulting in inaccurate position. In order to solve this problem, it is usually necessary to install an additional positioning mechanism to accurately define the position of the hub body. However, this solution not only increases the complexity and maintenance cost of the system, but also has many inconveniences in actual use, such as cumbersome operation and low efficiency. Therefore, how to simplify the hub body flipping mechanism, improve the accuracy and stability of flipping, and reduce the dependence on additional positioning mechanisms has become a technical problem that needs to be solved in the industry.

[0015] The beneficial effects of the present invention are as follows: Through the clamping mechanism provided in the present invention, when the hub body is flipped by the flipping mechanism, the flipping arm of the flipping mechanism drives the clamping housing to press downward against the surface of the non-flipped hub body, so that the first inclined surface of the snap ring contacts the side surface of the hub body, causing the snap ring to be extruded outward, and the elastic component is extruded. Until the convex block is pressed down to reach the position of the wheel groove on the side surface of the hub body, the snap ring is extruded toward the inside of the wheel groove by the restoring elastic force of the elastic component toward the inside, so that the snap ring is stuck in the wheel groove of the hub body to realize the clamping and locking of the hub body. Subsequently, the flipping arm of the flipping mechanism drives the entire clamping mechanism and the hub body to be flipped 180 degrees toward one side of the conveyor belt until the second inclined surface of the top block contacts and presses the unlocking groove inside the unlocking block, and as the flipping arm continues to press down, the unlocking block is extruded and slid outward by the top block, and the unlocking block drives the snap ring to slide outward until the snap ring completely leaves the wheel groove of the hub body, and the hub body is unlocked from the inside of the clamping mechanism and accurately placed on the other side of the conveyor belt, realizing the precise clamping and locking of the hub body during the flipping process, as well as the automatic unlocking and accurate placement after flipping, effectively simplifying the flipping mechanism, improving the accuracy and stability of flipping, and at the same time avoiding the use of an additional positioning mechanism, enhancing the operation efficiency and convenience; Through the provided flipping mechanism of the present invention, during use, the driving motor drives the rotating disk to rotate. The rotating disk drives the transmission rod and the rack to reciprocate up and down through the rotating rod. When the rack slides downward, it meshes with the runner through the tooth groove, driving the runner to rotate counterclockwise by 180 degrees. The flipping arm on the other side of the runner drives the clamping mechanism and the hub body clamped in the middle to flip 180 degrees on the surface of the conveyor belt. After flipping, the hub body is unlocked and placed down. Subsequently, the rack slides upward to the limit and then slides downward, driving the runner to rotate clockwise. The flipping arm on the other side of the runner drives the clamping mechanism to rotate towards the unflipped hub body and clamp and fix the unflipped hub body. By continuously rotating the rotating disk through the driving motor, automatic clamping, 180-degree flipping, and precise placement of the hub body are achieved, simplifying the operation process, improving the flipping efficiency and accuracy, and ensuring the stability and safety of the hub body during the flipping process; Through the provided conveying mechanism of the present invention, when conveying the hub body, the driving motor drives the transmission shaft to rotate. The transmission shaft drives the sliding rod to rotate through the connecting rod. When the sliding rod approaches the grooved pulley, it is caught in the sliding groove of the grooved pulley, driving the grooved pulley to rotate a certain angle. The grooved pulley drives the first tooth block to rotate through the rotating shaft. The first tooth block drives the conveying roller to rotate a certain angle through the linkage belt and the second tooth block, so that the hub body on the surface of the conveyor belt is conveyed a certain distance. When the hub body is clamped and locked by the clamping mechanism, the hub body is in a static state. When the hub body is completely flipped and unlocked and placed down, the sliding rod slides into the sliding groove of the grooved pulley, driving the grooved pulley to rotate a certain angle. The flipped hub body and the unflipped hub body are conveyed forward a certain distance through the conveyor belt, so that the unflipped hub body is conveyed to the position where the previous hub body was clamped and locked, and the flipped hub body is sent out of the inner side of the clamping mechanism, achieving precise control and positioning of the hub body during the conveying process, ensuring the stable conveying of the hub body before and after flipping, simplifying the conveying process, improving the conveying efficiency, and providing a reliable guarantee for the continuous processing of the hub body.

Detailed implementation manners

[0017] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0018] Refer to Figures 1-9 , an automatic flipping and positioning device for hub surface machining, including the following embodiments:

[0019] Embodiment 1: An automatic flipping and positioning device for hub surface processing, comprising flipping mechanisms 3 installed on both sides of the main board 2, which are used to automatically flip the hub body 6 on the surface of the conveying mechanism 5; the flipping mechanism 3 includes a rotating disk 303, a rotating wheel 308 and a flipping arm 312. The rotating disk 303 is rotatably connected to the lower part of the outside of the main board 2. One side of the rotating disk 303 is rotatably connected to a transmission rod 305 through a rotating rod 304. The upper end of the transmission rod 305 is fixedly connected to a rack 307. The rotating wheel 308 is rotatably connected to the upper part of the outside of the main board 2. One side of the rotating wheel 308 is fixedly connected to a flipping plate 310. The flipping arm 312 is fixedly connected to the side surface of the flipping plate 310; a driving motor 302 is fixedly connected to the lower part of the inside of the main board 2 through a motor base 301. The rotating disk 303 is drivingly connected to the output end of the driving motor 302. The transmission rod 305 is slidably connected to the outside surface of the main board 2 through a fixing block 306. A tooth groove 309 is formed on the side surface of the rotating wheel 308. The rotating wheel 308 is meshed with the rack 307 through the tooth groove 309. Two groups of flipping mechanisms 3 are provided. The two groups of flipping mechanisms 3 are respectively installed on the surfaces of the main boards 2 on both sides. The two groups of flipping mechanisms 3 are connected to each other through a connecting shaft rod 311. The connecting shaft rod 311 is fixedly connected to the inside of the two flipping plates 310 to realize the synchronous rotation of the two flipping plates 310. During use, the driving motor 302 drives the rotating disk 303 to rotate. The rotating disk 303 drives the transmission rod 305 and the rack 307 to realize up and down reciprocating sliding through the rotating rod 304. When the rack 307 slides downward, it is meshed with the rotating wheel 308 through the tooth groove 309, driving the rotating wheel 308 to rotate counterclockwise by 180 degrees. The flipping arm 312 on the other side of the rotating wheel 308 drives the clamping mechanism 4 and the hub body 6 clamped in the middle to flip 180 degrees on the surface of the conveyor belt 511. After flipping, the hub body 6 is unlocked and put down. Subsequently, the rack 307 slides upward to the limit and then slides downward, driving the rotating wheel 308 to rotate clockwise. The flipping arm 312 on the other side of the rotating wheel 308 drives the clamping mechanism 4 to rotate towards the unflipped hub body 6 and clamp and fix the unflipped hub body 6. By driving the rotating disk 303 to continuously rotate through the driving motor 302, automatic clamping, 180-degree flipping and precise placement of the hub body 6 are realized, the operation process is simplified, the flipping efficiency and accuracy are improved, and at the same time, the stability and safety of the hub body 6 during the flipping process are ensured.

[0020] Embodiment 2: The clamping mechanism 4 installed inside the flipping arm 312 is used for automatically positioning and clamping and releasing the hub body 6; the clamping mechanism 4 includes a snap ring 406, an unlocking block 404 and a top block 409. The snap ring 406 is movably connected to one side of the clamping housing 401 through an elastic component 403. The unlocking block 404 is fixedly connected to the side surface of the snap ring 406. A first inclined surface 407 is provided on the lower surface of the snap ring 406. A convex block 408 is fixedly connected to the inner side of the snap ring 406. An unlocking groove 405 is formed in the inner side of the unlocking block 404. The top block 409 is fixedly connected to the upper surface of the bracket 1. A second inclined surface 410 is provided on the side surface of the top block 409. During the process that the flipping arm 312 drives the clamping mechanism 4 and the hub body 6 to flip to one side of the conveyor belt 511, when the flipping arm 312 is about to be parallel to the horizontal plane, the flipping arm 312 presses down so that the unlocking block 404 of the clamping mechanism 4 is squeezed downward, and the unlocking groove 405 of the unlocking block 404 is squeezed downward and contacts the second inclined surface 410 of the top block 409. Through the squeezing action of the second inclined surface 410 of the top block 409, the unlocking block 404 drives the snap ring 406 to slide outward, realizing the unlocking and releasing of the hub body 6;A structural groove 402 is formed on the inner side of the clamping housing 401. The elastic component 403 and the unlocking block 404 are both located inside the structural groove 402. There are two sets of clamping mechanisms 4, and the two sets of clamping mechanisms 4 are respectively installed on the inner sides of the two flipping arms 312. By simultaneously clamping towards the middle or relaxing towards the two sides of the hub body 6 through the two sets of clamping mechanisms 4, stable clamping and relaxation of the hub body 6 are achieved. When the flipping mechanism 3 flips the hub body 6, the flipping arm 312 of the flipping mechanism 3 drives the clamping housing 401 to press down towards the surface of the non-flipped hub body 6, so that the first inclined surface 407 of the snap ring 406 contacts the side surface of the hub body 6, causing the snap ring 406 to be extruded outwards. The elastic component 403 is squeezed until the convex block 408 presses down to reach the position of the wheel groove 7 on the side surface of the hub body 6. Then, through the restoring elastic force of the elastic component 403 towards the inside, the snap ring 406 is extruded towards the inside of the wheel groove 7, so that the snap ring 406 is stuck in the wheel groove 7 of the hub body 6, realizing the clamping and locking of the hub body 6. Subsequently, the flipping arm 312 of the flipping mechanism 3 drives the entire clamping mechanism 4 and the hub body 6 to perform a 180-degree flip towards one side of the conveyor belt 511 until the second inclined surface 410 of the top block 409 contacts and squeezes the unlocking groove 405 inside the unlocking block 404. And as the flipping arm 312 continues to press down, the unlocking block 404 is extruded and slides towards the outside by the top block 409. The unlocking block 404 drives the snap ring 406 to slide towards the outside until the snap ring 406 completely leaves the wheel groove 7 of the hub body 6. The hub body 6 is unlocked from the inside of the clamping mechanism 4 and accurately placed on the other side of the conveyor belt 511. This realizes the precise clamping and locking of the hub body 6 during the flipping process, as well as the automatic unlocking and accurate placement after flipping, effectively simplifies the flipping mechanism 3, improves the accuracy and stability of flipping, and at the same time avoids the use of an additional positioning mechanism, enhancing the operation efficiency and convenience.;

[0021] Embodiment 3: The conveying mechanism 5 installed on the inner upper part of the bracket 1 is used to intermittently convey the hub body 6; a wheel groove 7 is formed on the side surface of the hub body 6, which is used to clamp and lock the hub body 6 by clamping the bump 408 inside the wheel groove 7. The conveying mechanism 5 includes a Geneva wheel 504, a conveying roller 508 and a conveyor belt 511. The Geneva wheel 504 is rotatably connected to the inner lower part of the main board 2 through a rotating shaft 506. A number of groups of sliding grooves 505 are formed on the surface of the Geneva wheel 504. The output end of the driving motor 302 is drivingly connected to a transmission shaft 501. A sliding rod 503 is fixedly connected to the side surface of the transmission shaft 501 through a connecting rod 502. When the sliding rod 503 rotates close to the Geneva wheel 504, it is clamped into the sliding groove 505 on the surface of the Geneva wheel 504 to drive the Geneva wheel 504 to rotate a certain angle. A first tooth block 507 is fixedly connected to the side surface of the rotating shaft 506. A second tooth block 509 is fixedly connected to one end of the conveying roller 508. The conveying roller 508 and the rotating shaft 506 are mutually drivingly connected through the first tooth block 507, the second tooth block 509 and a linkage belt 510. The conveying roller 508 is rotatably connected to the inner upper part of the bracket 1. A tensioning wheel 513 is rotatably connected to the inner side of the main board 2. The tensioning wheel 513 and the two conveying rollers 508 are mutually connected through a conveyor belt 511. When the Geneva wheel 504 is driven by the sliding rod 503 to rotate a certain angle, the conveying roller 508 is driven to rotate a certain angle, so that the hub body 6 on the surface of the conveyor belt 511 is conveyed a certain distance. A limiting groove 512 for limiting the position of the hub body 6 during conveying is formed on the outer surface of the conveyor belt 511. When conveying the hub body 6, the driving motor 302 drives the transmission shaft 501 to rotate. The transmission shaft 501 drives the sliding rod 503 to rotate through the connecting rod 502. When the sliding rod 503 approaches the Geneva wheel 504, it is clamped into the sliding groove 505 of the Geneva wheel 504, driving the Geneva wheel 504 to rotate a certain angle. The Geneva wheel 504 drives the first tooth block 507 to rotate the hub body 6 through the rotating shaft 506. The first tooth block 507 drives the conveying roller 508 to rotate a certain angle through the linkage belt 510 and the second tooth block 509, so that the hub body 6 on the surface of the conveyor belt 511 is conveyed a certain distance. When the hub body 6 is clamped and locked by the clamping mechanism 4, the hub body 6 is in a static state. When the hub body 6 is completely flipped and unlocked and lowered, the sliding rod 503 slides into the sliding groove 505 of the Geneva wheel 504, thereby driving the Geneva wheel 504 to rotate a certain angle. The flipped hub body 6 and the unflipped hub body 6 are conveyed forward a certain distance through the conveyor belt 511, so that the unflipped hub body 6 is conveyed to the position where the previous hub body 6 was clamped and locked. The flipped hub body 6 is sent out of the inner side of the clamping mechanism 4, realizing the precise control and positioning of the hub body 6 during the conveying process, ensuring the stable conveying of the hub body 6 before and after flipping, simplifying the conveying process at the same time, improving the conveying efficiency, and providing a reliable guarantee for the continuous processing of the hub body 6.

[0022] During use, the hub body 6 is placed in the limiting groove 512 on the surface of the conveyor belt 511 at a specified interval. The driving motor 302 is started. The driving motor 302 first drives the rotating disk 303 to rotate. By pulling the rotating rod 304, the transmission rod 305 and the upper rack 307 through the rotating disk 303, reciprocating up and down sliding is realized. The rack 307 meshes with the rotating wheel 308 through the tooth groove 309, and the number of teeth of the rack 307 is half of the number of teeth of the tooth groove 309 on the surface of the rotating wheel 308. Therefore, the reciprocating up and down sliding of the rack 307 drives the rotating wheel 308 to rotate 180 degrees and then rotate 180 degrees in the opposite direction to realize reciprocating rotation. At the same time, the turning plate 310 on one side of the rotating wheel 308 drives the turning arm 312 and the clamping mechanism 4 to perform reciprocating turning movements. When the clamping mechanism 4 turns to the unturned hub body 6, the first inclined surface 407 on the lower surface of the snap ring 406 contacts the side surface of the hub body 6 through the downward pressure of the clamping mechanism 4, causing the snap ring 406 to be extruded outward. At this time, the elastic component 403 is extruded. As the snap ring 406 continues to be pressed downward, until the convex block 408 inside the snap ring 406 is stuck in the wheel groove 7 of the hub body 6, the reset elastic force of the elastic component 403 pops the snap ring 406 inward and makes the convex block 408 stuck in the wheel groove 7 of the hub body 6, realizing the clamping and locking of the hub body 6. At this time, the turning arm 312 drives the clamping mechanism 4 and the hub body 6 to turn toward one side of the conveyor belt 511. When the clamping mechanism 4 and the hub body 6 turn to be gradually parallel to the horizontal plane, the second inclined surfaces 410 of the two top blocks 409 fixedly installed on both sides of the upper surface of the bracket 1 contact and squeeze the unlocking groove 405 of the unlocking block 404, causing the unlocking block 404 to pull the snap ring 406 and the convex block 408 to slide outward, realizing the unlocking of the hub body 6 until the convex block 408 completely leaves the wheel groove 7 of the hub body 6. At this time, the slide bar 503 fixedly connected to the side surface of the transmission shaft 501 rotates and is stuck in the sliding groove 505 of the grooved pulley 504, driving the grooved pulley 504 to rotate a certain angle. The grooved pulley 504 drives the first tooth block 507 to rotate through the rotating shaft 506. The rotating shaft 506 drives the second tooth block 509 and the conveyor roller 508 to rotate a certain angle through the first tooth block 507 and the linkage belt 510, so that the hub body 6 that has been turned over and unlocked on the surface of the conveyor belt 511 is conveyed forward a certain distance, causing the turned-over hub body 6 to leave the inside of the clamping mechanism 4, and conveying and moving the next unturned hub body 6 to the position to be clamped, waiting for the turning arm 312 to drive the clamping mechanism 4 to reset and clamp and turn over the unturned hub body 6. In this way, the turning and positioning of the hub body 6 are realized reciprocally.

[0023] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
