The diameter and surface roughness of the axle wheel seat and journal surfaces are crucial factors influencing wheelset assembly quality. For axle repair and maintenance, the development and research of intelligent axle grinding equipment is essential. Currently, grinding is done manually, which is time-consuming and labor-intensive. The dust generated during grinding also negatively impacts worker health. Furthermore, the varying skill and experience levels of workers lead to inconsistent axle grinding quality. Therefore, those skilled in the art have proposed an adaptive adhesive removal and cleaning device for railway axle maintenance to address the problems mentioned in the background section. Utility Model Content

[0003] The purpose of this invention is to provide an adaptive adhesive removal and cleaning device for railway axle maintenance, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An adaptive adhesive removal and cleaning device for railway axle maintenance includes a base plate, a material transfer component at the upper end of the base plate, support frames on both sides of the base plate, a ceiling rail fixedly connected to the upper end of the support frames, a robot on the ceiling rail, a grinding tool at the output end of the robot, and positioning components on both sides of the base plate.

[0006] Furthermore, the material transfer assembly includes pneumatic slide rails, lifting components, sliders, and auxiliary frames. A pair of pneumatic slide rails are fixedly connected to the upper end of the base plate, and a set of sliders are provided on the pneumatic slide rails. A lifting component is fixedly connected to the upper end of the sliders, and two sets of auxiliary frames are fixedly connected to the base plate, with the auxiliary frames placed between the two pneumatic slide rails.

[0007] Furthermore, the positioning component includes a left positioning receiving component and a right positioning receiving component. The left positioning receiving component and the right positioning receiving component are provided on both sides of the base plate, and the left positioning receiving component and the right positioning receiving component are symmetrically arranged.

[0008] Furthermore, the positioning assembly also includes positioning components. Positioning components are provided on both the left and right positioning receiving components, and the axle to be ground is engaged by the positioning components on the left and right positioning receiving components.

[0009] Furthermore, the positioning component also includes a transfer auxiliary head, a limiting rod, a transfer plate, a lifting plate, and a longitudinal lifting slide rail. The longitudinal lifting slide rail is fixedly connected to the right positioning receiving component, and the lifting plate is slidably connected to the longitudinal lifting slide rail. The right positioning receiving component is also fixedly connected to the limiting rod. The lifting plate is slidably connected to the limiting rod, and the transfer plate is fixedly connected to the lifting plate. The upper surface of the transfer plate is provided with a transfer auxiliary head.

[0010] Furthermore, the left positioning receiving component is similar to the right positioning receiving component, and is equipped with a transfer auxiliary head, a limiting rod, a transfer plate, a lifting plate, and a longitudinal lifting slide rail.

[0011] Furthermore, a tool storage rack is fixedly connected to the upper end of the right-side positioning and receiving component. A set of tool fixing plates is provided on the tool storage rack, and grinding tools are set on the tool storage rack through these tool fixing plates.

[0012] By adopting the above technical solution

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The pneumatic slide rail can drive the slider to move stably and quickly. Combined with the lifting component, the height and position of the axle can be flexibly adjusted. The auxiliary frame further ensures the stability of the axle during the transfer process. This component replaces the traditional method of manual handling and axle adjustment, which not only greatly reduces the manpower input, but also realizes the automation and efficient transfer of the axle. It avoids the fatigue and inefficiency of manual operation, allowing the axle to reach the grinding and cleaning station quickly and accurately, saving a lot of time for subsequent glue removal and cleaning operations, and significantly improving the overall maintenance efficiency.

[0015] 2. The robot installed on the overhead rail, equipped with grinding tools, can automatically complete the degumming and cleaning of the axle according to the preset program. The robot operation is characterized by strong continuity and stable operation speed. Unlike manual operation, it does not need to rest frequently and can always maintain a consistent work rhythm. Compared with manual grinding and cleaning, it further shortens the processing time of a single axle and effectively increases the number of repairs per unit time.

[0016] 3. By engaging the positioning components with the axle to be polished, the axle can be firmly and precisely fixed in the designated position, preventing the axle from shifting or shaking during the adhesive removal and cleaning process. The stability of the axle position allows the robot to accurately target the areas with adhesive layers when it drives the polishing tools, avoiding problems such as incomplete or excessive polishing caused by axle displacement. This ensures a more thorough adhesive removal and cleaning, improves the quality of the axle after maintenance, and guarantees the safety and reliability of the railway axle in subsequent use.

[0017] 4. In traditional manual glue removal and cleaning operations, workers need to be in close contact with grinding tools and axles, which poses safety hazards such as being scratched by grinding debris or accidentally injured by tools. However, this device operates automatically through robots. Workers only need to set up programs and monitor the equipment's operation status in the background. They do not need to directly participate in the grinding and cleaning operations, which effectively avoids direct contact between workers and dangerous work areas, greatly reduces the probability of workplace accidents, and protects the personal safety of workers.

[0018] 5. The overall device integrates multiple automation technologies such as automated material transfer, precise positioning, and automated grinding and cleaning. From the transfer and positioning of the axle to the removal of adhesive and cleaning, it forms a complete automated operation process. This highly automated operation mode reduces the interference of human factors on the maintenance process, lowers the probability of human operation errors, and makes the maintenance and cleaning of railway axles more standardized and stable.

During this process, the staff does not need to directly participate in the grinding and cleaning operation, but only needs to monitor the working status of the robot 8, the wear of the grinding tool 7, and the effect of adhesive removal and cleaning of the axle through the control system in the background.

[0026] In this embodiment, the material transfer assembly includes pneumatic slide rails 5, lifting components 10, sliders 11, and auxiliary frames 12. A pair of pneumatic slide rails 5 are fixedly connected to the upper end of the base plate 4, and a set of sliders 11 are provided on the pneumatic slide rails 5. Lifting components 10 are fixedly connected to the upper end of the sliders 11. Two sets of auxiliary frames 12 are fixedly connected to the base plate 4, and the auxiliary frames 12 are placed between the two pneumatic slide rails 5. When the material transfer assembly is started, the loading and transfer of the axle begins. The worker places the axle 9 to be ground on the auxiliary frame 12 of the material transfer assembly. 2 provides initial support for the axle, preventing the axle from directly contacting the base plate 4 and causing wear. Subsequently, the control system sends a start command to the pneumatic slide rail 5, which drives the slider 11 to move stably and quickly along the slide rail direction. The lifting component 10 at the upper end of the slider 11 starts simultaneously and lifts upward according to preset parameters until it contacts the bottom of the axle and smoothly lifts the axle. Under the continuous action of the lifting component 10, the axle is adjusted to the preset height. Then, the pneumatic slide rail 5 continues to drive the slider 11 to move, conveying the axle to the workpiece where the positioning component is located.

[0027] In this embodiment, the positioning assembly includes a left positioning receiving component 3 and a right positioning receiving component 6. The left and right positioning receiving components 3 and 6 are symmetrically arranged on both sides of the base plate 4. The positioning assembly also includes positioning components 13, with each of the left and right positioning receiving components 3 and 6 having a positioning component 13. The positioning components 13 engage the axle 9 to be ground. The positioning assembly further includes a transfer auxiliary head 14, a limiting rod 15, a transfer plate 16, a lifting plate 17, and a longitudinal lifting slide rail 18. The longitudinal lifting slide rail 18 is fixedly connected to the right positioning receiving component 6, and the lifting plate 17 is slidably connected to the longitudinal lifting slide rail 18. The right positioning receiving component 6 is also fixedly connected to the limiting rod 15, and the lifting plate 17 is slidably connected to the limiting rod 15. A fixed component is also fixedly connected to the lifting plate 17. The transfer plate 16 has a transfer auxiliary head 14 on its upper surface. Similarly, the left positioning receiving component 3 has a transfer auxiliary head 14, a limiting rod 15, a transfer plate 16, a lifting plate 17, and a longitudinal lifting slide rail 18. The longitudinal lifting slide rail 18 drives the lifting plate 17 to rise and fall stably along the limiting rod 15. The lifting plate 17 drives the transfer plate 16 to rise and fall synchronously. The transfer auxiliary head 14 on the transfer plate 16 contacts the surface of the axle. By finely adjusting the height and position of the transfer auxiliary head 14, the longitudinal position of the axle is further adjusted. The left positioning receiving component 3 and the right positioning receiving component 6 start synchronously. The positioning components 13 on both are in contact with both ends or the outside of the axle through a snap-fit ​​structure according to the specifications of the axle 9 to be polished. Under the precise control of the control system, the positioning components 13 gradually tighten until the axle is firmly and accurately fixed in the designated position, so as to avoid the axle from shifting or shaking during the subsequent glue removal and cleaning process.

[0028] In this embodiment, a tool storage rack 19 is fixedly connected to the upper end of the right positioning and receiving component 6. A set of tool fixing plates 21 are provided on the tool storage rack 19, and a grinding tool 20 is set on the tool storage rack 19 through the tool fixing plates 21. During the operation of the robot 8, different types of tools on the tool storage rack 19 can be replaced by the quick-change device on the grinding tool 7, thereby completing grinding with different effects.

[0029] Material loading and transfer: The worker places the axle on the auxiliary frame 12, the pneumatic slide rail 5 moves with the slider 11, the lifting component 10 lifts the axle and adjusts it to the preset height, and transfers it to the positioning station. The auxiliary frame 12 ensures stability. Precise positioning: The position of the axle is adjusted by the longitudinal lifting slide rail 18, and then the positioning component 13 of the left and right positioning receiving component snaps the axle in place. Automated glue removal: The robot 8 moves along the overhead rail 1, and the grinding tool 7 operates according to the preset path. If necessary, the grinding tool 20 can be directly replaced by the quick-release device. During the process, the worker monitors the process from the background. After the operation is completed, the positioning component 13 is released, and the transfer component sends the axle to the unloading area.

[0030] The pneumatic slide rail 5 drives the slider 11 to move stably and quickly. Combined with the lifting component 10, the height and position of the axle can be flexibly adjusted. The auxiliary frame 12 further ensures the stability of the axle during the transfer process. This component replaces the traditional method of manual handling and axle adjustment, which not only greatly reduces manpower input, but also realizes the automated and efficient transfer of the axle. It avoids the fatigue and inefficiency of manual operation, allowing the axle to quickly and accurately reach the grinding and cleaning station, saving a lot of time for subsequent glue removal and cleaning operations, and significantly improving the overall maintenance efficiency; the machine installed on the overhead rail 1 The robot 8, equipped with the polishing tool 7, can automatically complete the adhesive removal and cleaning of the axle according to a preset program. The robot 8 features continuous operation and stable speed, eliminating the need for frequent breaks like manual labor and maintaining a consistent work rhythm. Compared to manual polishing, it further shortens the processing time for a single axle, effectively increasing the number of repairs per unit time. Through the locking engagement between the positioning component 13 and the axle 9 to be polished, the axle is firmly and precisely fixed in the designated position, preventing displacement or shaking during the adhesive removal and cleaning process, ensuring the stability of the axle position. This device allows the robot 8, which drives the grinding tool 7, to accurately target areas with adhesive layers, preventing inadequate or excessive grinding caused by axle displacement. This ensures more thorough cleaning and improves the quality of axle maintenance, guaranteeing the safety and reliability of railway axles in subsequent use. In traditional manual adhesive removal, workers need to be in close contact with the grinding tool 7 and the axle, posing safety hazards such as scratches from grinding debris and accidental injury from the tool. This device, with its automated operation via the robot 8, allows workers to simply set up the program and monitor the equipment's operation from the backend, eliminating the need for direct participation in the grinding and cleaning process. This effectively avoids direct contact between workers and hazardous work areas, significantly reducing the probability of workplace accidents and ensuring worker safety. The entire device integrates multiple automation technologies, including automated material handling, precise positioning, and automated grinding and cleaning. From axle transfer and positioning to adhesive removal and cleaning, it forms a complete automated workflow. This highly automated operation mode reduces human interference in the maintenance process, lowers the probability of human error, and makes the adhesive removal and cleaning work for railway axles more standardized and stable.
