[0001] This utility model relates to the field of wheel processing technology, and more specifically, to a wheel and axle processing production line and a wheel production line. Background Technology

[0002] The axle is the main body of the wheelset, connecting the axle and the wheel. The axle is fixed at both ends of the wheel axle, and rolling bearings are installed at each end of the axle. These rolling bearings are press-fitted onto the journals with an interference fit. The wheel is mounted on the journals at both ends of the axle, fixed to the axle by an interference fit or heat fitting, with the journals and wheel surfaces forming rolling contact. The wheel axle manufacturing process involves steps such as grease application, bearing press-fitting, dimensional inspection, front cover assembly, polishing, and painting.

[0024] like Figure 1 As shown, in this embodiment, the wheel and axle processing production line includes: a first conveying structure 10, a grease coating structure 20, a bearing pressing structure 30, a positioning dimension detection structure 40, a front cover assembly structure 50, a break-in structure 60, and a painting structure 70. The grease coating structure 20 is disposed on the first conveying structure 10. The bearing pressing structure 30 is disposed on the first conveying structure 10 and located downstream of the grease coating structure 20. The positioning dimension detection structure 40 is disposed on the first conveying structure 10 and located downstream of the bearing pressing structure 30. The front cover assembly structure 50 is disposed on the first conveying structure 10 and located downstream of the positioning dimension detection structure 40. The break-in structure 60 is disposed on the first conveying structure 10 and located downstream of the front cover assembly structure 50. The painting structure 70 is disposed on the first conveying structure 10 and located downstream of the break-in structure 60.

[0025] In this embodiment, the grease coating structure 20, bearing pressing structure 30, positioning dimension detection structure 40, front cover assembly structure 50, break-in structure 60, and painting structure 70 are all sequentially arranged on the first conveying structure 10. Through this arrangement, the axle enters the grease coating structure 20 from the first conveying structure 10 and is automatically greased. After grease coating, the first conveying structure 10 conveys the axle to the bearing pressing structure 30, completing the bearing installation. The axle then moves to the positioning dimension detection structure 40, where its dimensions are detected to test whether the bearing installation is in place. After detection, it enters the front cover assembly structure 50 for automatic front cover assembly. After assembly, it enters the break-in structure 60 for automatic break-in of the front cover, and then enters the painting structure 70 for automatic painting. In other words, the axle is automatically processed on the axle processing production line, thereby improving the production efficiency of axle processing. Therefore, the technical solution of this embodiment effectively solves the problems of high cost and low efficiency in axle processing in related technologies.

[0026] The technical solution of this embodiment integrates the grease coating structure 20, the bearing pressing structure 30, the positioning dimension detection structure 40, the front cover assembly structure 50, the break-in structure 60, and the painting structure 70 onto the first transmission structure 10, thereby realizing continuous and automated wheel and axle processing, significantly improving production efficiency and reducing production costs.

[0027] Specifically, the implementation of the wheel and axle processing production line not only significantly shortened the total cycle time of wheel and axle processing and increased daily production, but also reduced processing errors caused by human factors through automated control, ensuring the consistency and reliability of wheel and axle product quality.

[0028] like Figure 1 As shown, in this embodiment, the wheel and axle processing production line further includes a wheelset pressing structure 80 and a second conveying structure 90. The conveying direction of the second conveying structure 90 is angled to the conveying direction of the first conveying structure 10, and the second conveying structure 90 is docked with the first conveying structure 10. The docking point between the second conveying structure 90 and the first conveying structure 10 is located upstream of the grease coating structure 20. The wheelset pressing structure 80 is located at the end of the second conveying structure 90 away from the first conveying structure 10. This design not only optimizes the layout of the production line and improves space utilization, but also, through the introduction of the second conveying structure 90, enables efficient connection between different processes, further enhancing the flexibility and processing efficiency of the production line.

[0029] Specifically, by combining the wheelset pressing structure 80 with the second transmission structure 90, the wheel and axle processing production line can handle wheel and axle of various sizes and types, improving the adaptability and versatility of the production line.

[0030] like Figure 1 As shown, in this embodiment, the wheel and axle processing production line also includes a wheelset measuring structure 100. The wheelset measuring structure 100 is disposed on the first conveying structure 10 and located at the junction of the first conveying structure 10 and the second conveying structure 90. The wheelset measuring structure 100 can monitor the dimensions of the wheel and axle in real time, ensuring processing accuracy, effectively avoiding subsequent processing problems caused by dimensional deviations, and improving the product qualification rate.

[0031] like Figure 1 As shown, in this embodiment, a buffer area 11 is provided on the first conveying structure 10, and the buffer area 11 is located upstream of the grease coating structure 20. The buffer area 11 can effectively balance the processing speed of each process in the production line, avoid the overall production progress from being affected by the delay of a certain process, and at the same time, it also provides a buffer space for production line adjustments in case of emergencies, thereby enhancing the stability and reliability of the wheel and axle processing production line.

[0032] Specifically, the rational layout of the buffer area 11 is crucial for the smooth operation of the wheel and axle processing production line. It can not only adjust the production line's cycle time to ensure that each process has sufficient time to complete processing, but also temporarily store the wheel and axle to be processed when equipment malfunctions or requires maintenance, avoiding a complete halt to the production line and reducing losses caused by production interruptions.

[0033] like Figure 1 As shown, in this embodiment, the wheel and axle processing production line also includes a bearing feeding platform 110 and a first robotic arm. Both the bearing feeding platform 110 and the first robotic arm are located on the side of the first conveying structure 10 and between the grease coating structure 20 and the bearing pressing structure 30. By automatically picking up and placing bearings with the first robotic arm, the bearing pressing process is automated, reducing labor costs and improving pressing accuracy and speed.

[0034] Specifically, the cooperation between the bearing feeding platform 110 and the first robotic arm enables the production line to quickly adapt to different types of bearing pressing requirements. The high-precision operation of the first robotic arm ensures the accuracy and consistency of bearing pressing, reduces wheel and axle failures caused by uneven pressing, and improves the service life and safety of wheel and axles.

[0035] like Figure 1 As shown, in this embodiment, the wheel and axle processing production line also includes a front cover mounting platform 121, a third conveyor structure 122, and a second robot arm. The front cover mounting platform 121, the third conveyor structure 122, and the second robot arm are all located on the side of the first conveyor structure 10 and between the positioning dimension detection structure 40 and the front cover assembly structure 50. The third conveyor structure 122 is located between the front cover mounting platform 121 and the first conveyor structure 10, and the second robot arm is positioned between the third conveyor structure 122 and the front cover mounting platform 121. This design ensures the high efficiency and accuracy of front cover assembly, reduces errors caused by manual operation, and is suitable for wheel and axle processing with complex front cover types and high assembly requirements.

[0036] Specifically, the introduction of the front cover matching platform 121 enables the wheel and axle processing production line to handle front covers of various shapes and sizes, improving assembly flexibility and production efficiency. The automated operation of the second robotic arm not only reduces labor costs but also improves the accuracy and speed of front cover assembly, ensuring the sealing and stability of the wheel and axle.

[0037] like Figure 1 As shown, in this embodiment, the wheel and axle processing production line also includes a marking structure 130, which is located at the end of the third conveyor structure 122 away from the first conveyor structure 10. The marking structure 130 enables automated marking, rapid recording and traceability of product information, and improves the efficiency of production management.

[0038] Specifically, the use of the automated marking structure 130 not only simplifies the production management process, but also improves the transparency and traceability of wheel and axle manufacturing through real-time recording and traceability of product information.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the grease coating structure 20 includes a first oil spraying structure 21 and a second oil spraying structure 22, which are located on both sides of the first conveying structure 10. The dual-sided arrangement of the first oil spraying structure 21 and the second oil spraying structure 22 ensures that the grease forms a uniform and dense coating on the axle surface, improving the axle's corrosion resistance and lubrication performance. Furthermore, this design reduces grease consumption, lowers production costs, and improves the company's economic efficiency.

[0040] like Figure 1 and Figure 2 As shown, in this embodiment, the grease coating structure 20 includes a drive structure 23, which can cooperate with the wheel drive to drive the wheel to rotate. By driving the wheel to rotate through the drive structure 23, a uniform grease coating can be formed on the wheel surface, avoiding the problem of uneven grease distribution caused by static grease application, and improving the uniformity and durability of the grease coating.

[0041] Specifically, the combination of the drive structure 23 and the grease coating structure 20 allows the grease to be evenly distributed in every corner of the wheel, especially in critical areas such as the inner and outer sides of the wheel and the rim, forming an effective lubrication and protective layer. This ensures that the wheel axle maintains good operating condition under various harsh working conditions, reduces maintenance costs, and improves equipment reliability.

[0042] In this embodiment, the driving structure includes a first pushing structure and a second pushing structure. The first pushing structure and the second pushing structure are distributed on the outer side of the two wheels and are respectively driven and cooperated with the two wheels. The first pushing structure and the second pushing structure can push the wheels to rotate.

[0043] Specifically, the first pushing structure includes a first telescopic rod and a second telescopic rod, and the second pushing structure includes a third telescopic rod and a fourth telescopic rod. The end of the first telescopic rod is hinged with a first arc-shaped block, the end of the second telescopic rod is hinged with a second arc-shaped block, the end of the third telescopic rod is hinged with a third arc-shaped block, and the end of the fourth telescopic rod is hinged with a fourth arc-shaped block. The first and second arc-shaped blocks abut against the same wheel, and the third and fourth arc-shaped blocks abut against another wheel. When the first and third telescopic rods extend, the second and fourth telescopic rods retract, at which time the wheel can rotate in a first direction. When the first and third telescopic rods retract and the second and fourth telescopic rods extend, the wheel can rotate in a second direction.

[0044] According to another aspect of this application, a wheel production line is provided. This embodiment of the wheel production line includes a wheel and axle processing production line, which is the aforementioned wheel and axle processing production line. The aforementioned wheel and axle processing production line automates the entire process of wheel and axle processing, from pressing, oiling, inspection, assembly to grinding and painting, greatly improving production efficiency and reducing labor costs. Simultaneously, through precise dimensional inspection and quality control, it ensures the processing accuracy of the wheel and axles, improving the overall quality of the product. Furthermore, the modular design of this production line facilitates maintenance and upgrades, adapts to different types of wheel and axle processing needs, and has broad application prospects. Through the above-mentioned optimized design, the wheel and axle processing production line not only improves processing efficiency and reduces production costs but also effectively ensures product quality, achieving intelligent and high-precision wheel and axle processing. Therefore, the wheel production line with the aforementioned wheel and axle processing production line also possesses the above-mentioned advantages.
