Description

Technical Field

[0001] The utility model belongs to the technical field of spoke processing, and in particular relates to a spoke cooling and transmission device. Background Art

[0002] The spokes are the connecting structure on the wheel hub, which maintains the structural strength of the entire wheel hub. When the wheel hub is subjected to the load of the vehicle, the spokes will increase the structural strength of the wheel hub to resist the large pressure load borne by the wheel hub.

[0003] During the production and processing of spokes, after the spoke blanks produced by casting are die-casted with iron parts, the spokes need to be transferred to the next process through a conveyor for further processing, such as transferring the spokes to a cutting lathe to remove the excess structure on the spokes.

[0004] Specifically, a robotic arm grabs the spokes from the die-casting lathe and loads them onto a conveyor belt. Then, a robotic arm grabs the spokes at the discharge end of the conveyor belt and feeds them into the cutting equipment.

[0005] However, in actual operation, it was discovered that when the robotic arm grabs the spokes from the die-casting lathe and loads them onto the conveyor belt, the spokes with special-shaped structures cannot maintain a fixed posture during the transmission process on the conveyor belt. Therefore, during the transmission process, not only are the spokes prone to rolling and sliding on the conveyor belt, but when the spokes are transmitted to the end position of the conveyor belt, the change in the spoke posture makes it difficult for the robotic arm to grasp the spokes. Therefore, in actual operation, when the spokes with special-shaped structures that are prone to change their posture during transmission are transmitted to the unloading end position (end) of the conveyor belt, it is difficult for the robotic arm to accurately grasp the spokes, resulting in the need for manual posture correction during actual operation. However, this method not only results in low processing efficiency, but also has a high risk of manual posture correction. Specifically, the high-speed operating robotic arm is very likely to collide with the operator's hands and body, thereby causing production safety accidents.

[0006] Therefore, keeping the spoke posture unchanged during the transmission process can not only greatly improve production efficiency, but also greatly increase production safety. Utility Model Content

[0042] Example 1

[0043] like Figure 1-4 As shown, a spoke cooling transmission device includes a conveyor. Specifically, the conveyor is a conventional chain conveyor disclosed in the prior art, and its main structure includes a frame 41 and a chain conveyor belt 42 installed on the frame 41. The chain conveyor belt 42 is driven by a motor, a transmission roller and other structures installed on the frame 41.

[0044] During the loading process, the robotic arm grabs the spokes produced by the previous process equipment and loads them onto the chain conveyor belt 42. In order to avoid excessive changes in the posture of the spokes with high irregularities during transportation, which makes it difficult for the robotic arm on the next working equipment to grab the materials when unloading, a guide rail mechanism 43 is fixedly installed on the above-mentioned frame 41 and is spaced apart from the conveyor belt.

[0045] The guide rail mechanism 43 is used to transfer the spokes in a sliding, guiding and limiting manner.

[0046] Specifically, the spokes are loaded onto the guide rail mechanism 43 , and the bottom of the spokes is subjected to the friction force of the conveyor belt and slides and transmits on the guide rail mechanism 43 .

[0047] Specifically, the guide rail mechanism 43 includes a first disconnected guide rail structure and a second continuous guide rail 432 spaced apart on both sides; the first disconnected guide rail structure includes a short guide rail 434 (fixed on the frame 41 and kept spaced apart from the chain conveyor belt 42) and a long guide rail 432 corresponding to the short guide rail 434.

[0048] The second continuous guide rail 432 and the long guide rail 432 are fixedly connected via a cantilever mounting structure 433 , and the long guide rail 432 , the second continuous guide rail 432 and the conveyor belt are spaced apart by the cantilever mounting structure 433 .

[0049] Specifically, the long guide rail 432 and the second continuous guide rail 432 are cantilevered as follows:

[0050] The cantilever mounting structure 433 includes a pad mounting seat respectively fixedly connected to the frame 41, the top of the pad mounting seat is fixedly connected to a T-shaped fixing seat 4331, the T-shaped fixing seat 4331 is fixedly assembled with a mounting rod 4332, the inner end of the mounting rod 4332 is fixedly connected to an end fixing seat 4333, the bottom of the end fixing seat 4333 is fixedly connected to a connecting column 4334 set vertically downward, and the connecting column is fixedly connected to a bottom fixing seat 4335; the bottom fixing seat 4335 is fixedly connected to a cantilever fixing rod 4336 fixedly connected to the corresponding second continuous guide rail 432 and the long guide rail 432.

[0051] At the same time, the second continuous guide rail 432 is set horizontally, the long guide rail 432 is set obliquely, and the right end of the long guide rail 432 is inclined toward the long guide rail 432; a guide gap is formed between the long guide rail 432 and the second continuous guide rail 432.

[0052] During operation, when the robotic arm grabs the spoke and loads it between the short guide rail 434 and the second continuous guide rail 432, the spoke is supported between the short guide rail 434 and the second continuous guide rail 432, and the bottom of the spoke is supported on the chain plate conveyor 42. Under the friction force of the chain plate conveyor 42, the spoke slides between the short guide rail 434 and the second continuous guide rail 432, and continues to slide after switching from between the short guide rail 434 and the second continuous guide rail 432 to between the long guide rail 432 and the second continuous guide rail 432.

[0053] Because the spokes are supported on the long guide rail 432 and the second continuous guide rail 432, and the long guide rail 432 and the second continuous guide rail 432 limit the spokes, the posture of the spokes will not change randomly during the transmission process. When the spokes move to the end of the long guide rail 432 and the second continuous guide rail 432, the posture of the spokes will still not change, which makes it easier for the robotic arm to clamp the spokes.

[0054] This method solves the technical defect that the spoke posture is easily changed during the transmission process of the traditional conveyor belt, which makes it difficult for the robotic arm to accurately grasp the spoke during the blanking process.

[0055] Example 2

[0056] like Figure 1-4 As shown, based on the structure of Example 1, the spoke cooling and transmission device of this embodiment further includes a stop mechanism 44 fixedly connected to the unloading end of the conveyor belt; the spoke is transmitted to the unloading end of the conveyor belt and is stopped by the stop mechanism 44.

[0057] The stop mechanism 44 includes a stop plate, the front and rear ends of which are fixedly connected to the frame 41 respectively, and the bottom of the stop plate is spaced apart from the conveyor belt.

[0058] The shape of the stop plate is:

[0059] The stopper plate includes a trapezoidal portion 442 (front side), which is integrally formed with a rectangular portion 441 (rear side). The trapezoidal portion 442 and the rectangular portion 441 are each fixedly mounted to the frame 41 via a plurality of connecting plates 443. Specifically, the top of the frame 41 is fixedly connected to a spacer block to which the connecting plates 443 are mounted.

[0060] At the same time, the inner side wall of the trapezoidal portion 442 has an inclined guide surface 4421. When the spoke is transferred to the stop plate position, the spoke slides toward the rectangular portion position with higher support stability under the guidance of the inclined guide surface 4421 and stops on the stop plate. At this time, the robotic arm grabs the spoke.

[0061] The stop plate of the above structure can stably stop the wheel spoke, making it easier for the robot arm to stably grasp the material.

[0062] Example 3

[0063] like Figure 1-4 As shown, this embodiment builds on the structure of Example 2. To achieve controlled loading, the spoke cooling and conveying device further includes a first sensor structure for controlling loading and a second sensor structure for controlling conveyor operation, in accordance with existing methods. Specifically, the first sensor structure includes a plurality of first infrared sensors 45 installed between the left side of the frame 41 (the first infrared sensors 45 are spaced apart front to back). The second sensor structure includes a plurality of second infrared sensors 46 installed between the right side of the frame 41.

[0064] The first infrared sensor 45 is used to detect whether there is a spoke between the short guide rail 434 and the second continuous guide rail 432. If yes, the first infrared sensor 45 controls the robot arm to stop loading the spoke according to the conventional control method disclosed in the prior art.

[0065] As in the conventional method, a second infrared sensor 46 detects whether there is a spoke at the stop plate position. If there is, the second infrared sensor 46 controls the conveyor to stop transporting the spokes according to the conventional control method to prevent the spokes from accumulating. When the spoke at that position is picked up by the robot arm, the conveyor continues to transport the spokes.

[0066] Example 4

[0067] like Figure 1-4 As shown, this embodiment is based on the structure of embodiment 2. Since the surface temperature of the spokes is relatively high after being die-cast in the previous die-casting process, in order to achieve cooling, according to the existing cooling method, the spoke cooling and transmission device also includes an air cooling mechanism at the top position of the frame 41.

[0068] Similar to the existing air cooling method, a fan bracket (not shown) is installed between the top of the rack 41, and several cooling fans 47 are installed on the fan bracket. The cooling fans 47 drive the cooling air flow toward the conveyor belt to cool the conveying spokes.

[0069] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
