Description

Technical Field

[0001] This invention relates to the field of wheel hub processing technology, and in particular to a wheel hub precision machining equipment. Background Technology

[0002] Battery wheel hubs are usually manufactured by die casting, which involves pressing an upper mold with a lower mold. The resulting wheel hub requires further finishing, which is usually done on a lathe.

[0003] Because battery wheel hubs are small in size, they need to be produced in large quantities. During production, they can simply be placed in a lathe and wait for the lathe to process them before being taken out. However, large-scale production requires workers to manually load and unload the materials, which places high demands on the workers and is relatively inefficient. Summary of the Invention

[0004] To address the problem that existing technologies require manual loading and unloading of materials during large-scale production of battery wheel hubs, which places high demands on workers and results in relatively low efficiency, this application provides a wheel hub precision machining equipment, the specific solution of which is as follows.

[0005] A wheel hub precision machining equipment includes a storage and retrieval mechanism, a conveying mechanism, and a processing mechanism. The storage and retrieval mechanism includes a processing area and a finished product area. Both the processing area and the finished product area are provided with storage and retrieval rods, which are used to place wheel hubs. The storage and retrieval mechanism further includes an infeed conveyor belt and an outfeed conveyor belt. The conveying mechanism includes a conveyor frame. One end of the infeed conveyor belt is set to the processing area, and the other end of the infeed conveyor belt is set to the conveyor frame. One end of the outfeed conveyor belt is set to the finished product area, and the other end of the outfeed conveyor belt is set to the conveyor frame. A horizontal moving component is set on the conveyor frame. The horizontal moving component is slidably connected to the conveyor frame and moves along the conveyor frame. When the horizontal moving component moves, it can be aligned with the outfeed conveyor belt and the infeed conveyor belt respectively. The horizontal moving component is also provided with a vertical moving component, and the vertical moving component is provided with a rotating component. The rotating component is rotatably connected to the vertical moving component. The rotating component is provided with a double-headed gripper, and the double-headed gripper is rotatably connected to the vertical moving component. Each end of the double-headed gripper is provided with a gripper head, and each gripper head is capable of gripping the wheel hub. The machining mechanism includes a machine tool for inserting the wheel hub and performing turning.

[0006] By adopting the above technical solution, a conveyor frame is set up and the wheel hubs are transported by a double-headed gripper. The double-headed gripper can transport two wheel hubs at the same time, which speeds up the production line cycle. Then, the wheel hubs are turned and finished by a machining mechanism. The production process does not require too many workers and can be carried out more stably and efficiently.

[0007] Optionally, the access mechanism further includes an access rack, which is also provided with a vertical moving component and a horizontal moving component with the same structure. The vertical moving component is fixedly provided with an access gripper, and the access gripper is also provided with a gripper head, which is used to grip the wheel hub.

[0008] By adopting the above technical solutions, the storage and retrieval grippers can perform the two processes of feeding and feeding the wheel hub simultaneously, which can effectively reduce the footprint of the wheel hub processing equipment and complete the storage and retrieval of workpieces within a smaller range, thereby reducing costs to a certain extent.

[0009] Optionally, the gripper head includes a double-headed cylinder, with piston rods at both ends of the double-headed cylinder that move synchronously. A clamping plate is provided on the piston rod of the double-headed cylinder, and the clamping plate can clamp the wheel hub on both sides. Multiple clamping wheels are rotatably provided on the clamping plate corresponding to the wheel hub. The clamping wheels can abut against the wheel hub and are driven to rotate by a motor, and the clamping wheels can drive the wheel hub to rotate.

[0010] By adopting the above technical solution, the double-headed cylinder can synchronously drive the clamping plates on both sides to move towards the wheel hub, thereby fixing the wheel hub. The clamping wheel can drive the wheel hub to rotate by rotating, so that the wheel hub can be aligned with the machine tool tool during subsequent processing.

[0011] Optionally, a positioning ring is also provided on the lower side of the access gripper. The positioning ring is fixedly connected to the gripper head and does not interfere with the clamping plate. The positioning ring is used to abut against and position the wheel hub.

[0012] By adopting the above technical solutions, the positioning ring can abut against the wheel hub, avoiding excessive contact between the wheel hub and the clamping plate, which would cause interference and affect clamping, thus improving the stability of clamping the wheel hub.

[0013] Optionally, the positioning ring is provided with a positioning groove corresponding to the protrusion of the wheel hub, the positioning groove is for the wheel hub to be inserted into, and a squeezing nozzle is provided in the positioning groove. The squeezing nozzle is positioned facing the center of the wheel hub. When the wheel hub enters the positioning groove, it can push the squeezing nozzle. The squeezing nozzle is used to store water-based marking liquid, and the squeezing nozzle can spray the marking liquid along the protrusion of the wheel hub.

[0014] By adopting the above technical solutions, the positioning groove can further locate the protrusion of the wheel hub. After positioning, it can be directly positioned according to the position of the wheel hub protrusion. When it is sent into the machine tool for processing, it can be directly aligned with the angle to be processed without further adjustment of the wheel hub angle. The extrusion nozzle and the sprayed water-based marking liquid can further assist in processing. After applying the water-based marking liquid, it is more convenient to judge the position and angle of the wheel hub, further improving the convenience and accuracy of finishing.

[0015] Optionally, a guide plate is provided on the positioning ring corresponding to the extrusion nozzle. The guide plate is arranged along the protrusion of the hub. Multiple adsorption heads are also embedded on the positioning ring. The adsorption heads can adsorb the hub. Multiple air nozzles are provided inside the guide plate. The air nozzles are connected to the adsorption heads. The air nozzles can blow gas toward the protrusion of the hub to assist the marking liquid to spread evenly and dry.

[0016] By adopting the above technical solution, the guide plate can guide the spraying of water-based marking liquid, so that the water-based marking liquid can be sprayed more accurately on the location to be marked, while the adsorption head can fix the hub more stably. When adsorbing the hub, the air nozzle starts to work to assist the marking liquid to spread evenly and dry.

[0017] Optionally, a turning frame is provided between the feeding conveyor belt and the conveyor frame. A turning slide is slidably provided on the turning frame. A turning seat is rotatably provided on the turning slide. A turning claw is provided on the turning seat. The turning claw is used to hold the hub. A clamping wheel is also rotatably provided on the turning claw.

[0018] By adopting the above technical solution, setting up flipping grippers and clamping wheels, the hub can be effectively flipped, and the clamping wheels can drive the hub to rotate, adjusting the angle of the hub so that the hub angle can be adjusted to align with the machine tool's cutting tool.

[0019] Optionally, the flipping frame is also equipped with a vision sensor, which is electrically connected to the flipping gripper and is oriented toward the flipping gripper. The vision sensor is used to detect the position and angle of the wheel hub and then control the rotation of the flipping gripper. The vision sensor can read the marking liquid and control the flipping gripper to rotate the wheel hub.

[0020] By adopting the above technical solution, the visual sensor can effectively determine the position of the wheel hub protrusion, read the water-based marking liquid on it, effectively determine the angle of the wheel hub, and adjust the wheel hub for subsequent machine tool processing.

[0021] Optionally, a cleaning assembly is also included, which is located at one end of the conveyor frame near the discharge conveyor belt. The cleaning assembly includes a cleaning frame and a cleaning air pump. The cleaning frame has a cleaning groove for the wheel hub to be inserted into, and the cleaning air pump is used to blow air onto the wheel hub.

[0022] By adopting the above technical solution, some debris will remain on the wheel hub after the machine tool is processed, and water-based marking liquid will also adhere to the wheel hub. Therefore, it is necessary to spray and dry the wheel hub with a cleaning nozzle to complete the cleaning and further improve the convenience.

[0023] Optionally, a cleaning nozzle is also provided at the cleaning trough. The cleaning nozzle is used to spray cleaning fluid containing cleaning debris and labeling liquid onto the wheel hub. A collection pipe is also provided on the cleaning rack. The collection pipe is used to discharge the cleaning fluid and debris.

[0024] By adopting the above technical solutions, the cleaning nozzles can clean the water-based marking liquid, thereby reducing the difficulty of cleaning the water-based marking liquid adhering to the wheel hub. Furthermore, the cleaning liquid and debris can be discharged through the collection pipe, avoiding the accumulation of cleaning liquid and debris.

[0025] In summary, this application has at least the following beneficial effects: This application solves the problem that in the mass production of battery wheel hubs, workers are required to manually load and unload materials, which is demanding on workers and relatively inefficient. This application sets up an automated transportation and processing flow, which requires less worker involvement and has high processing efficiency, thereby reducing the requirements for workers and improving processing accuracy. This application also improves the convenience of finishing by setting up components that can mark and clean the wheel hub, enabling the wheel hub to be marked and adjusted in position to complete the finishing process, and further reducing manual intervention.

[0032] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] A wheel hub precision machining equipment, such as Figure 1 and Figure 2 As shown, the system includes a storage and retrieval mechanism 1, a conveying mechanism 2, and a processing mechanism 3. The storage and retrieval mechanism 1 includes a processing area 11 and a finished product area 12. Both the processing area 11 and the finished product area 12 are equipped with storage and retrieval rods 13 for placing wheel hubs. In a specific implementation, the wheel hubs are hollow, allowing them to be stacked one by one on the storage and retrieval rods 13. In other embodiments, a pushable frame can be placed under the processing area or the finished product area 12 to push the wheel hubs out, further improving convenience.

[0034] like Figure 1 and Figure 2 As shown, the storage and retrieval mechanism 1 also includes a feeding conveyor belt 21 and a discharging conveyor belt 22. The conveying mechanism 2 includes a conveyor frame 23. One end of the feeding conveyor belt 21 is set to the processing area 11, and the other end of the feeding conveyor belt 21 is set to the conveyor frame 23. One end of the discharging conveyor belt 22 is set to the finished product area 12, and the other end of the discharging conveyor belt 22 is set to the conveyor frame 23. The feeding conveyor belt 21 and the discharging conveyor belt 22 are actually conveyor belts with racks on their inner sides. A sliding platform is also set on its inner side. The platform is driven by the racks to achieve cyclic reciprocating motion, thereby completing the conveying of the hub. In other embodiments, a common reciprocating conveyor belt can also be used for transportation, and the effect is actually similar.

[0035] like Figure 1 and Figure 2As shown, a horizontal moving component 232 is provided on the conveyor frame 23. The horizontal moving component 232 is slidably connected to the conveyor frame 23 and moves along the conveyor frame 23. When the horizontal moving component 232 moves, it can be aligned with the discharge conveyor belt 22 and the feed conveyor belt 21 respectively. A vertical moving component 231 is also provided on the horizontal moving component 232. A rotating component 233 is provided on the vertical moving component 231. The rotating component 233 is rotatably connected to the vertical moving component 231. A double-headed gripper 24 is provided on the rotating component 233. The double-headed gripper 24 is rotatably connected to the vertical moving component 231. Each end of the double-headed gripper 24 is provided with a gripper head 241, and both gripper heads 241 can grip the wheel hub. In practical implementation, both the horizontal moving component 232 and the vertical moving component 231 adopt linear mechanisms based on the same principle, which can effectively guide the horizontal and vertical axis movement of the double-headed gripper 24. The double-headed gripper 24, in conjunction with the rotating component 233, can rotate along multiple axes and simultaneously clamp two workpieces, further improving workpiece processing efficiency. The processing mechanism 3 includes a machine tool 31, which is used to place the wheel hub and perform turning. Its working principle is the same as that of a conventional machine tool 31. However, it should be noted that the processing of the machine tool 31 requires pre-programming; therefore, the wheel hub needs to be aligned at a pre-set angle during processing.

[0036] like Figure 1 and Figure 2 As shown, the storage and retrieval mechanism 1 also includes a storage and retrieval rack 14, which is also equipped with a vertical moving component 231 and a horizontal moving component 232 with the same structure. A storage and retrieval gripper 15 is fixedly mounted on the vertical moving component 231, and a gripper head 241 is also provided on the storage and retrieval gripper 15. The gripper head 241 is used to grip the wheel hub. In specific implementation, the gripper head 241 can effectively grip and place the wheel hub, thereby completing the feeding and discharging of the wheel hub.

[0037] like Figure 3 As shown, the gripper head 241 includes a double-headed cylinder 242. Both ends of the double-headed cylinder 242 are equipped with piston rods that move synchronously. A clamping plate 243 is mounted on the piston rod of the double-headed cylinder 242. The clamping plate 243 can clamp the wheel hub on both sides. Multiple clamping wheels 244 are rotatably mounted on the clamping plate 243 corresponding to the wheel hub. The clamping wheels 244 can abut against the wheel hub and are driven to rotate by a motor, thus driving the wheel hub to rotate. In a specific implementation, the clamping wheels 244 are driven by a miniature motor. like Figure 2 and Figure 3 As shown, a positioning ring 151 is also provided on the lower side of the access gripper 15. The positioning ring 151 is fixedly connected to the gripper head 241. The positioning ring 151 and the clamping plate 243 do not interfere with each other. The positioning ring 151 is used to abut and position the wheel hub. In specific implementation, the positioning ring 151 is directly fixed to the gripper head 241 through a connecting rod, and the wheel hub is positioned by abutting against it.

[0038] like Figure 3 and Figure 4 As shown, a positioning groove 152 is provided on the positioning ring 151 corresponding to the protrusion of the wheel hub. The positioning groove 152 is for the wheel hub to be inserted into. A squeezing nozzle 153 is provided in the positioning groove 152, facing the center of the wheel hub. When the wheel hub enters the positioning groove 152, it can push the squeezing nozzle 153. The squeezing nozzle 153 is used to store water-based marking liquid, and the squeezing nozzle 153 can spray the marking liquid along the protrusion of the wheel hub. In specific implementation, the positioning groove 152 can determine the position for the wheel hub protrusion to be inserted, thereby positioning the angle when the wheel hub is fed into the lathe, so that the wheel hub can be accurately processed. When the positioning is accurate, the squeezing nozzle 153 is pressurized and sprays water-based marking liquid to mark the position of the wheel hub protrusion, which can more accurately determine the angle of the wheel hub. Water-based marking liquid uses water as a solvent and is divided into dye type and pigment type according to the colorant. According to the function, it is divided into washable, fluorescent, fast-drying, etc., and is widely used in industrial scenarios that require temporary marking and require environmental protection and easy cleaning.

[0039] like Figure 3 and Figure 4 As shown, a guide plate 154 is provided on the positioning ring 151 corresponding to the extrusion nozzle 153. The guide plate 154 is arranged along the protrusion of the wheel hub. Multiple adsorption heads 155 are also embedded in the positioning ring 151. The adsorption heads 155 can adsorb the wheel hub. Multiple air nozzles 156 are provided in the guide plate 154. The air nozzles 156 are connected to the adsorption heads 155. The air nozzles 156 can blow gas towards the protrusion of the wheel hub to assist in the even spreading and drying of the marking liquid. In specific implementation, the wheel hub can only be attached and adsorbed when the protrusion is aligned with the positioning groove 152 of the positioning ring 151. During adsorption, the extrusion nozzle 153 can spray water-based marking liquid, and the air nozzles 156 blow gas to spread the water-based marking liquid and achieve a certain drying effect.

[0040] like Figure 1As shown, a turning frame 25 is provided between the feeding conveyor belt 21 and the conveyor frame 23. A turning slide 251 is slidably mounted on the turning frame 25, and a turning seat 252 is rotatably mounted on the turning slide 251. A turning gripper 253 is mounted on the turning seat 252, and the turning gripper 253 is used to grip the hub. A gripping wheel 244 is also rotatably mounted on the turning gripper 253. A vision sensor 254 is also provided on the turning frame 25. The vision sensor 254 is electrically connected to the turning gripper 253 and is positioned facing the turning gripper 253. The vision sensor 254 is used to detect the position and angle of the hub and then control the rotation of the turning gripper 253. The vision sensor 254 can read the marking liquid and control the turning gripper 253 to rotate the hub. In practice, the flipping frame 25 moves as follows: the flipping slide 251 slides up and down to a position where it can grip the wheel hub. After gripping the wheel hub, the angle of the wheel hub is adjusted by rotating the gripping wheel 244 on the flipping jaw 235. Then, the entire flipping seat 252 is flipped so that the wheel hub is flipped upwards, so that the wheel hub can be aligned and gripped for the next processing step.

[0041] like Figure 1 and Figure 5 As shown, it also includes a cleaning assembly 26, which is located at one end of the conveyor frame 23 near the discharge conveyor belt 22. The cleaning assembly 26 includes a cleaning frame 261 and a cleaning air pump 262. The cleaning frame 261 has a cleaning groove 263 for the wheel hub to be inserted into, and the cleaning air pump 262 is used to blow air onto the wheel hub. A cleaning nozzle 264 is also provided at the cleaning groove 263, which is used to spray cleaning debris and cleaning fluid (marking liquid) onto the wheel hub. A collection pipe 265 is also provided on the cleaning frame, which is used to discharge the cleaning fluid and debris. In specific implementation, the machine tool 31 will drill debris on the wheel hub during processing, so it is necessary to clean the wheel hub with the cleaning air pump 262 and the cleaning nozzle 264, while the collection pipe 265 can discharge the debris and cleaning fluid.

[0042] Working principle: The precision machining device with an automated process can perform precision machining on each wheel hub according to the process cycle, reducing the need for manual labor and effectively improving processing efficiency.

[0043] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
