Description

[0002] Automation is an inevitable driving force behind the rapid development of modern technology and industrialization. In the production of wheel spokes, the simplistic manual operation mode and outdated production pace have become industry drawbacks. Automated processing and operation of wheel spokes are now entering the market. Specifically, existing technologies face the following technical problems:

[0003] (1) The lifting mechanism is designed in the center and also needs to be designed with a centering structure. The mechanism needs to solve the problem of large variation range of wheel spoke diameter and integrated lifting and rotation design.

[0004] (2) The range of wheel spoke models is large and the identification and positioning of the wheel spoke rotation air hole is required. Therefore, a lifting mechanism needs to be designed. The lifting mechanism is suitable to be designed in the middle lifting center. The linkage-type centering clamping mechanism and gear-type centering clamping mechanism commonly used in the industry are characterized by high design difficulty, high cost, bulky structure, and poor stability. Moreover, the rotation axis of the above-mentioned existing technology mechanism is set in the center, which will interfere with the lifting and rotating mechanism when the lifting and rotating are performed.

[0070] A chain centering, lifting, and rotating mechanism includes a body 1, a transmission component 2, a centering component 3, and a lifting and rotating component 4;

[0071] The main body 1 includes a receiving area 5 and a working area 6;

[0072] The receiving area 5 is used to receive wheel spokes from the output end of the previous process;

[0073] The centering component 3 and the lifting and rotating component 4 are located in the working area 6 of the main body 1;

[0074] The transmission component 2 provided on the main body 1 is used to transmit the spokes from the receiving area 5 to the working area 6;

[0075] The centering component 3 is used to adjust the position of the spokes so that the center of the spokes is located on the central axis of the mechanism;

[0076] The lifting and rotating assembly 4 is used to lift and rotate the centered wheel spokes simultaneously. The lifted and rotated wheel spokes are then picked up by the robot in the next process and removed from the mechanism.

[0077] This application discloses a chain-driven centering and lifting rotation mechanism, a piece of equipment used in the production process of wheel spokes. This equipment ensures accurate gripping and rotational vent identification and positioning of the wheel spokes while they are rotating face down, thereby automating the wheel spoke production process. Due to the wide range of wheel spoke models in industry and the need for vent identification and positioning, a lifting mechanism is required, ideally located at the center of the lifting operation. Conventionally used linkage-type and gear-type centering and gripping mechanisms in the industry are characterized by high design difficulty, high cost, bulky structure, and poor stability. This application addresses the problems of existing technologies by designing a chain-driven centering and lifting rotation mechanism.

[0078] like Figure 1 , 4 As shown in Figures 6 and 7, as a further embodiment of this embodiment, the transmission component 2 includes a pad 7 disposed on the body 1 and a roller 8 rotatably disposed on the pad 7.

[0079] The pads 7 and the rollers 8 are arranged in parallel and at equal intervals;

[0080] The roller 8 is driven to rotate, thereby transmitting the spokes placed on it.

[0081] As a further embodiment of this example, the roller 8 is driven by a drive sprocket at the output end of the motor 9 to drive the drive chain, thereby causing the drive chain to drive the driven sprocket at the end of the roller 8 to rotate, thus making all the rollers 8 rotate synchronously.

[0082] As a further embodiment of this example, the transmission component 2 includes an overall transmission unit 10 and a segmented transmission unit 11;

[0083] The overall transmission unit 10 is located in the non-working area 6 on the main body 1;

[0084] The roller 8 provided at the overall transmission section 10 is a single unit;

[0085] The segmented transmission unit 11 is disposed in the working area 6 on the main body 1;

[0086] The rollers 8 provided in the segmented transmission section 11 are a pair of rollers 8 arranged opposite each other and spaced apart, and the gap between the pair of rollers 8 is used to avoid the lifting and rotating assembly 4.

[0087] As a further embodiment of this invention, the transmission component 2 further includes a material stop 12;

[0088] The baffle 12 is detachably or movably mounted on the body 1 and is used to block the spoke from continuing to advance when the center of the spoke reaches the axial centerline of the centering assembly 3.

[0089] The position of the baffle 12 is adjusted on the body 1 according to the size of the wheel spokes.

[0090] The chain-aligning lifting and rotating mechanism disclosed in this application receives wheel spokes from the previous process, and the spokes are transported to the working area 6 via the transmission component 2. Before reaching the working area 6, the transmission component 2 operates using a single, integral roller 8. One end of the roller 8, driven by a motor 9 and a drive chain, is the driving end, and the other end is the driven end. At the working area 6, each roller 8 is divided into two sections (i.e., two short rollers 8 arranged coaxially at intervals), with the working area 6 between them. At this time, both sections of the roller 8 are driven and move synchronously.

[0091] like Figure 3 , 6 As shown in Figures 7 and 8, as a further embodiment of this embodiment, the centering component 3 includes a pushing cylinder 13, a first pushing part 14, a second pushing part 15, and a chain centering structure 16.

[0092] The push cylinder 13 is fixedly mounted on the body 1;

[0093] The first pushing unit 14 is connected to the output end of the pushing cylinder 13;

[0094] The second pushing part 15 is disposed on the opposite side of the first pushing part 14, and moves synchronously in the opposite direction to the first pushing part 14 through the chain centering structure 16.

[0095] As a further embodiment of this embodiment, the chain alignment structure 16 includes a first sprocket 17 and a second sprocket 18 disposed on the body 1, a first connecting plate 19 disposed on the first pushing part 14, a second connecting plate 20 disposed on the second pushing part 15, and a synchronous chain 21 disposed on the first sprocket 17 and the second sprocket 18.

[0096] The first connecting plate 19 and the second connecting plate 20 are disposed between the first sprocket 17 and the second sprocket 18;

[0097] The synchronization chain 21 includes chain segment A 22 and chain segment B 23;

[0098] One end of the A-segment chain 22 is connected to the end of the first connecting plate 19 away from the first sprocket 17. After the chain extends towards the second sprocket 22, it passes around the second sprocket 18, and the other end of the A-segment chain 22 is connected to the end of the second connecting plate 20 close to the second sprocket 22.

[0099] One end of the B-segment chain 23 is connected to the end of the second connecting plate 20 away from the second sprocket 18. After the chain extends towards the first sprocket 17, it passes around the first sprocket 17, and the other end of the B-segment chain 23 is connected to the end of the first connecting plate 19 close to the first sprocket 17.

[0100] The synchronization chain 21 is connected to the first connecting plate 19 or the second connecting plate 20 via an end connector;

[0101] One end of the end connector is fixedly mounted on the first connecting plate 19 or the second connecting plate 20, and the other end is hinged to the end of the synchronous chain 21 by screws.

[0102] As a further embodiment of this embodiment, the first pushing part 14 includes a first substrate 24 and two pushing rods 25;

[0103] The two push rods 25 are symmetrically arranged on the first substrate 24;

[0104] The first connecting plate 19 is fixedly disposed at the end of the first substrate 24 away from the push rod 25;

[0105] The main body 1 is provided with a first limiting plate 26, and the first limiting plate 26 and the first substrate 24 are arranged opposite each other in the vertical direction.

[0106] The first limiting plate 26 is provided with a limiting groove 27, and the push rod 25 is disposed in the limiting groove 27;

[0107] The second pushing part 15 includes a second substrate 28 and two pushing rods 25;

[0108] The two push rods 25 are symmetrically arranged on the second base plate 28;

[0109] The second connecting plate 20 is fixedly disposed at the end of the second substrate 28 away from the push rod 25;

[0110] The main body 1 is provided with a second limiting plate 29, and the second limiting plate 29 and the second substrate 28 are arranged opposite each other in the vertical direction;

[0111] The second limiting plate 29 is provided with a limiting groove 27, and the push rod 25 is disposed in the limiting groove 27.

[0112] The chain centering and lifting rotation mechanism disclosed in this application enables the first pushing part 14 and the second pushing part 15 to move synchronously through the chain centering structure 16. When the pushing cylinder 13 drives the first pushing part 14 to move toward the second pushing part 15, the B segment of the chain 23 is pulled by the first connecting plate 19, thereby driving the second connecting plate 20 and the second pushing part 15 to move closer to the first pushing part 14; when the pushing cylinder 13 drives the first pushing part 14 to move away from the second pushing part 15, the A segment of the chain 22 is pulled by the first connecting plate 19, thereby driving the second connecting plate 20 and the second pushing part 15 to move away from the first pushing part 14. During this process, since the first sprocket 17 and the second sprocket 18 are of equal size and parallel, when the synchronous chain 21 moves in the horizontal direction, the approach distance between the first connecting plate 19 and the second connecting plate 20 is the same, thereby enabling the two sides of the centering assembly 3 to move synchronously toward or away from the center, ensuring precise centering operation.

[0113] like Figure 4 , 5 As shown, as a further embodiment of this example, the lifting and rotating assembly 4 includes a lifting cylinder 30, a drive motor 31, a lifting plate 32, and a lifting and rotating plate 33.

[0114] The lifting cylinder 30 is fixedly mounted on the main body 1;

[0115] The lifting plate 32 is connected to the output end of the lifting cylinder 30;

[0116] The drive motor 31 is fixedly connected to the lifting plate 32;

[0117] The output end of the drive motor 31 is directly or indirectly connected to the lifting rotating plate 33.

[0118] As a further embodiment of this embodiment, the drive motor 31 is connected to the lifting rotating plate 33 through a reduction gear set 34;

[0119] The reduction gear set 34 includes a first gear 35 and a second gear 36 that mesh with each other.

[0120] The diameter of the first gear 35 is smaller than the diameter of the second gear 36;

[0121] The first gear 35 is connected to the output end of the drive motor 31;

[0122] The upper end face of the second gear 36 is fixedly connected to the lifting rotating plate 33 by fasteners.

[0123] The chain centering, lifting, and rotating mechanism disclosed in this application first transmits the spokes to the working area 6 via the transmission component 2, where they are then centered by the centering component 3. After centering, the lifting and rotating mechanism begins operation. The lifting cylinder 30, fixed to the main body 1, raises and lowers the other components as a whole. After the drive motor 31 starts, it drives the first gear 35 to rotate. The smaller diameter first gear 35 drives the meshing second gear 36 to rotate. The angular velocity of the second gear 36 is less than that of the first gear 35, thus achieving deceleration. The lifting and rotating plate 33 rotates with the second gear 36, thereby lifting and rotating the spokes placed on it. The robot in the next process then removes the spokes for subsequent operations. The drive motor 31 is then turned off, and the lifting cylinder 30 resets.

[0124] By adopting the above technical solution, this application has the following beneficial effects:

[0125] (1) Through the coordinated work of the transmission component 2, the centering component 3 and the lifting and rotating component 4, the mechanism realizes the full automation of the wheel spoke from receiving, transmission, centering to lifting and rotating, which provides a strong guarantee for the automated operation of the wheel spoke production process and significantly improves production efficiency.

[0126] (2) Through the precise design of the centering component 3, it is ensured that the center of the wheel spokes can be accurately located on the central axis of the mechanism, providing reliable conditions for the robot to accurately grip the wheel spokes when they are running face down, reducing the risk of gripping failure or damage due to positional deviation. The centering component 3 realizes the synchronous reverse movement of the first pushing part 14 and the second pushing part 15 through the chain centering structure 16, ensuring the accuracy of the centering operation, further improving the accuracy of the wheel spoke positioning, and providing a good foundation for subsequent processing.

[0127] (3) In view of the large range of wheel spoke models in industry, the mechanism can adapt to wheel spokes of different sizes and shapes through the adjustable baffle 12, which enhances the versatility and flexibility of the equipment.

[0128] (4) The lifting and rotating assembly 4 adopts a design combining a lifting cylinder 30 and a drive motor 31 to achieve smooth lifting and rotation of the wheel spokes. By introducing a reduction gear set 34, the speed control during the rotation process is further optimized, ensuring the stability and accuracy of the wheel spoke rotation, which facilitates the robot in the next process to identify and locate the air vents.

[0129] (5) Compared with the linkage or gear-type centering and clamping mechanisms commonly used in the industry, the chain centering structure 16 of this application is simpler in design, reducing design difficulty and manufacturing cost, while improving the stability and reliability of the equipment.

[0130] (6) By cleverly designing the structure of the transmission component 2 in the working area 6 (such as using a pair of oppositely arranged and spaced rollers 8), the lifting and rotating component 4 is effectively avoided, making the entire mechanism structure more compact, saving space, and facilitating flexible arrangement on the production line.

[0131] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.
