Description

Technical Field

[0001] This utility model relates to the technical field of wheel rolling transfer equipment, specifically to a conveying device for preparing double-rimmed wheels. Background Technology

[0002] In the industrial manufacturing process of double-flanged wheels, the conveying and transfer of wheel blanks is a crucial link connecting core processes such as forging, machining, and testing. Its operational efficiency, safety, and equipment protection directly affect the overall production line's capacity, product qualification rate, and equipment lifespan. As a core load-bearing component in rail transportation, heavy machinery, and other fields, the blanks of double-flanged wheels have significant characteristics: firstly, they are large and heavy, with single blanks typically weighing hundreds of kilograms or even tons, requiring extremely high stability during transfer; secondly, after completing hot working processes such as forging, the surface temperature of the blank is usually maintained at a high level, a characteristic that can easily damage contact equipment during subsequent conveying and reversing operations. Furthermore, the asymmetrical profile formed by the double-flanged protrusions further increases the difficulty of controlling the blank's posture, especially when it needs to be changed from a horizontal state (wheel axis parallel to the conveying surface) to a vertical state (wheel axis perpendicular to the conveying surface) to adapt to subsequent gripper grasping or processing equipment feeding, placing even stricter demands on the rationality of the operational plan. In existing technologies, the industry generally adopts an integrated operation mode of "robotic arm-integrated clamping-transfer-reversal" for the conveying and reversing of double-flanged wheel blanks. Specifically, conventional conveying devices can only achieve horizontal linear conveying of wheel blanks and cannot autonomously complete posture adjustment. When the production process requires the blank to be changed from a horizontal to a vertical state, it must rely entirely on the robotic arm to perform the operation: first, the clamping mechanism at the end of the robotic arm clamps the flange or hub of the blank, and then the robotic arm rotates through multi-degree-of-freedom joints to drive the blank to complete lifting, reversing (usually 90° or 180°), and transfer actions, finally sending the blank adjusted to a vertical state to the target station. Although this mode achieves the posture conversion and transfer function of the blank to a certain extent, in practical applications, due to the characteristics of the blank's large weight and high temperature, it exposes many unavoidable defects, which seriously restrict the stable operation and efficiency improvement of the production line. First, the risk of falling is significant, resulting in poor safety. Due to the extreme weight of the wheel blank, the robotic arm must simultaneously bear the gravitational load of the blank and the inertial load generated by the reversing motion during clamping and reversing. When the clamping mechanism wears down due to long-term use, the clamping force weakens, or the driving torque of the robotic arm joints deviates due to load fluctuations, the blank is highly susceptible to slippage and falling accidents. Such accidents not only lead to deformation and scrapping of valuable blanks, causing direct economic losses, but may also cause impact damage to surrounding equipment on the production line, and even threaten the personal safety of operators. In high-frequency transfer scenarios, the probability of this risk increases significantly. Secondly, the robotic arm is prone to burns from prolonged contact with high-temperature blanks, resulting in severe equipment wear and tear. The surface temperature of double-flanged wheel blanks is typically high immediately after heat treatment, while the gripping mechanism of the robotic arm is mostly made of metal, and some joints and wiring have poor tolerance to high-temperature environments. In the integrated "gripping-transfer-reversing" mode, the robotic arm needs to be in direct contact with the high-temperature blank for extended periods (covering the entire process of gripping, lifting, reversing, and transferring), causing heat to be rapidly conducted to the gripping mechanism and the robotic arm itself. Over time, this leads to performance degradation of the gripping mechanism material due to high temperatures, such as decreased hardness and deformation, further reducing gripping stability. Furthermore, high temperatures easily damage the lubricating grease, seals, and wiring insulation layers inside the robotic arm joints, resulting in increased failure frequency and a significantly shortened lifespan. This not only increases equipment maintenance and replacement costs but also affects the continuous operation efficiency of the production line due to frequent equipment downtime. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a conveying device for preparing double-rimmed wheels. This device uses a reversing module to change the orientation of the wheel blank during transport, transforming it from a horizontal to a vertical state. This facilitates gripping and transport by the clamps. Compared to existing methods that use a robotic arm to hold the blank before reversing it during transport, this step-by-step approach avoids the risk of the wheel blank falling due to its excessive weight. It also prevents the robotic arm from being burned due to prolonged contact between the blank and the robotic arm.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a conveying device for preparing double-rimmed wheels, comprising a clamping module and a reversing module. The clamping module includes a frame with grippers slidably disposed on the frame. The reversing module includes a base located below the frame, a support above the base, a rotating shaft at the upper part of the support, a flipping plate at the middle of the rotating shaft, and a limiting plate at the lower part of the flipping plate.

[0005] As a further improvement to the above technical solution: The upper part of the flip plate is provided with a clearance groove, which is coaxially distributed with the flip plate.

[0006] The limiting plate is arc-shaped, and the top of the arc of the limiting plate coincides with the center line of the flipping plate. Supporting ribs are provided on both sides of the top of the arc below the limiting plate.

[0007] The bracket is provided with a support column and a flip-limiting column on both sides, and the bottom of the flip plate is provided with a slot corresponding to the position of the flip-limiting column.

[0008] The upper part of the support column is provided with a support plate that fits against the lower surface of the flip plate.

[0009] The gripper includes a mounting base, with gripping arms at both ends of the mounting base, and a drive source for rotating the gripping arms is provided on the upper part of the mounting base.

[0010] The drive source includes a telescopic push rod, the output end of which is provided with a double-sided rack, and the upper part of both gripping arms is provided with a meshing toothed disc.

[0011] The gantry is equipped with a traveling trolley connected to a drive source.

[0012] The beneficial effects of this utility model embodiment are as follows: The conveying device for preparing double-rimmed wheels includes a clamping module and a reversing module. The clamping module includes a frame with grippers slidably mounted on it. The reversing module includes a base located below the frame, a support above the base, a rotating shaft on the upper part of the support, a flipping plate in the middle of the rotating shaft, and a limiting plate at the lower part of the flipping plate. By reversing the wheel blank during the transfer process through the reversing module, the wheel blank is reversed from a horizontal to a vertical state, which facilitates the clamping and transfer of the grippers. Compared with the existing method of using a robotic arm to clamp the blank and then reversing it during transfer, the distributed operation method can avoid the risk of the wheel blank falling due to its excessive weight. It can also avoid the risk of the robotic arm being burned due to prolonged contact between the wheel blank and the robotic arm. Under the premise of ensuring stable transfer, it can reduce the time and cost of equipment cooling, thereby improving the continuity of operation. Attached Figure Description

[0015] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0016] like Figure 1-5 As shown, the conveying device for manufacturing double-rimmed wheels in this embodiment includes a clamping module and a reversing module. The clamping module is based on a frame 1, wherein a traveling trolley 19 is directly mounted on the frame 1 and can move horizontally along the frame 1. It is connected to a drive source 15 to provide power support for the movement of the clamping components. As the power core of the clamping action, the drive source 15 includes a telescopic push rod 16 and a double-sided rack 17. The double-sided rack 17 is mounted on the output end of the telescopic push rod 16 and can move up and down with the extension and retraction of the telescopic push rod 16. The core actuator of the gripping module is the gripper, which consists of a mounting base 13 and two gripping arms 14. The two gripping arms 14 are respectively mounted on both ends of the mounting base 13, and each gripping arm 14 has a meshing toothed disc 18 on its upper part. The meshing toothed disc 18 meshes with the double-sided rack 17 of the drive source 15. When the double-sided rack 17 moves with the telescopic push rod 16, it can drive the two gripping arms 14 to rotate synchronously through tooth transmission, thereby realizing the gripping and releasing action of the wheel. The reversing module is located below the clamping module, with the base 2 as the mounting base. Its core support structure is the bracket 3, which is fixedly installed above the base 2. Supporting columns 9 and flipping limiting columns 10 are respectively set on both sides, and a rotating shaft 4 is installed on the upper part. The middle part of the flipping plate 5 is connected to the rotating shaft 4 on the upper part of the bracket 3, and can rotate around the rotating shaft 4 to realize the flipping action, providing a bearing base for wheel reversal. The upper part of the flipping plate 5 has a clearance groove 7, which is coaxially distributed with the flipping plate 5 to avoid interference between components during wheel placement and flipping. At the same time, the bottom of the flipping plate 5 has a locking groove 11, which corresponds to the position of the flipping limiting column 10 on the side of the bracket 3. When the flipping plate 5 is flipped to a specific angle, the locking groove 11 can engage with the flipping limiting column 10 to achieve precise limiting of the flipping angle. A limiting plate 6 is provided at the lower part of the tilting plate 5. The limiting plate 6 has an overall arc-shaped structure, with its apex coinciding with the center line of the tilting plate 5. It is used to laterally limit the wheels placed on the tilting plate 5 and prevent the wheels from shifting during the tilting process. Below the limiting plate 6, there are also supporting ribs 8, which are located on both sides of the apex of the arc. These supporting ribs enhance the structural strength of the limiting plate 6 and ensure the stability of the limiting effect. In addition, a support plate 12 is installed on the upper part of the support column 9. Its top surface is in contact with the lower surface of the tilting plate 5. When the tilting plate 5 is in the initial horizontal position, it can provide bottom support for the tilting plate 5 and ensure the stability of the tilting plate 5 when it carries the wheels. The working principle / assembly process of this solution is as follows: The rolled wheel blank is placed on the flipping plate 5. At this time, the flipping plate 5 is in a horizontal state, and the wheel blank is placed flat on the flipping plate 5. Then the flipping plate 5 rotates from the horizontal position to the direction of the frame 1. After the rotation is completed, the angle between the flipping plate 5 and the base 1 is 5-10 degrees. The rotation of the flipping plate 5 changes the flat wheel blank to a vertical state. At this time, the traveling trolley 19 drives the gripper to move above the wheel blank and transfer it to the forming device for secondary processing.
