[0026] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-3 A fixed tool comprises a base 300 and at least one positioner 400 arranged on the base 300; a C-frame 410 is provided at the output end of the positioner 400, and a driving push rod 420 is provided on one side of the C-frame 410; it also comprises a lifting platform 100 fixed on the base 300, and a positioning tool 200 is provided on the lifting platform 100; the positioning tool 200 comprises a limit frame 210, a servo motor 220 is provided on the side of the limit frame 210, and a co-directional twin screw 230 is provided at the output end of the servo motor 220, a screw sleeve 240 is installed on the external thread of the co-directional twin screw 230, and a clamp seat 250 is fixed on the top of the screw sleeve 240.

[0028] The base 300 serves as the foundation of the entire tooling and provides a stable support. The positioner 400 is mounted on the base and is used to adjust the position of the C-frame 410 to meet different cleaning requirements. A driving push rod 420 is provided on one side of the C-frame 410. By extending and retracting the driving push rod 420, the position and angle of the C-frame 410 can be changed, thereby clamping or loosening the bogie. The lifting platform 100 is fixed on the base 300 and is used to adjust the height of the entire positioning tooling. The lifting platform 100 includes but is not limited to electric / hydraulic / starting / screw / scissor lifts, which can be safely selected. The bogie can be adjusted to different heights by rising or falling the lifting platform 100. The positioning tooling 200 includes a limit frame 210, and a servo motor 220 is provided on its side. The servo motor 220 drives the co-rotating twin screws 230 through precise control, and the rotation of the co-rotating twin screws 230 drives the screw sleeve 240 to move. A clamp seat 250 is fixed on the top of the screw sleeve 240. When the screw sleeve 240 moves along the double screw 230 , the clamp seat 250 will move accordingly to clamp or release the bogie.

[0029] The bogie is placed on the positioning tooling 200 through a suspension device. After the servo motor 220 is activated, the co-directional twin screws 230 driven act on the screw sleeve 240. The screw sleeve 240 cooperates with the co-directional twin screws 230 to feed and move. The clamping seat 250 on the top of the screw sleeve 240 will move from the inside to the outside accordingly, thereby clamping the steering port on the inner side of the bogie. After the bogie is fixed, laser cleaning operation is performed. After cleaning is completed, the driving push rod 420 on the C-frame 410 drives the two sides of the bogie to be clamped, and the servo motor 220 is operated in reverse to make the clamp seat 250 release the bogie, and then the lifting platform 100 moves down to make room for the turning of the bogie, and the positioner 400 is used to drive the C-frame 410 to turn it over with the bogie, and the lifting platform 100 moves up and aligns with the bogie to clamp the bogie again by driving the servo motor 220, and the driving push rod 420 is operated in reverse to make the C-frame 410 disengage from the clamping of the bogie, and at this time, the reverse side of the bogie is laser cleaned.

[0030] In some embodiments, the bottom of the limiting frame 210 is provided with guide rails 211 located on both sides of the screw sleeve 240 , and the bottom of the clamping seat 250 is fixed with sliders 251 located on the top of the guide rails 211 , and the sliders 251 slide along the guide rails 211 .

[0031] The design of the guide rail 211 and the slider 251 provides a flexible adjustment method, so that the clamping seat can be moved within a certain range as needed, increasing the adaptability of the tooling. The precise positioning of the clamping seat 250 can be achieved by sliding the slider 251 on the guide rail 211. This precise control is essential to ensure the correct position of the bogie during the laser cleaning process.

[0032] Guide rails 211 are installed at the bottom of the limit frame 210. These guide rails can be linear guide rails or curved guide rails, depending on the path requirements for the movement of the clamping base 250. A slider 251 is fixed at the bottom of the clamping base 250. The slider 251 matches the guide rail 211 to ensure stability and guidance during the sliding process. When the position of the clamping base 250 needs to be adjusted, the operator can push or pull the clamping base 250 to slide the slider 251 along the guide rail 211. This sliding can be manual or achieved by mechanical or electric means. After the clamping base 250 is moved to the appropriate position, the slider 251 can be fixed by a locking mechanism (such as a screw, a wedge block or other fixing device) to ensure that the clamping base remains stable during the laser cleaning process.

[0033] In some embodiments, the clamp seat 250 is an L-shaped plate, and a rib plate is provided on the inner side of the L-shape of the clamp seat 250. The design of the L-shaped plate provides a larger contact area, which helps to disperse the force and enhance the overall structural strength of the clamp seat. The shape of the L-shaped plate makes the clamp seat more stable when it cooperates with the guide rail 211, reduces shaking during the sliding process, and ensures the accuracy of the clamping process.

[0034] The clamp seat 250 is designed with an L-shaped plate. This shape usually has a long side and a short side. The long side is used to contact the guide rail 211, and the short side is in contact with the bogie for clamping the bogie; or the long side is in contact with the bogie, and the short side is in contact with the guide rail 211. The specific adjustment can be adaptive. Ribs are arranged on the inner side of the L-shaped plate. These ribs can be horizontal or vertical, and are used to enhance the structural strength of the clamp seat to prevent deformation when subjected to force. During the laser cleaning process, the clamp seat 250 stably clamps the bogie through its L-shaped structure and ribs to ensure that the bogie does not move or slide during the cleaning process. The clamp seat 250 slides along the guide rail 211 through the slider 251 at its bottom to adjust the clamping position. The design of the L-shaped plate allows the clamp seat to remain stable when sliding, and the ribs provide additional support.

[0035] In some embodiments, the top of the lifting platform 100 is provided with a lifting platform 260 located on both sides of the limiting frame 210. The lifting platform 260 is located on both sides of the limiting frame 210 to provide a stable support point for the bogie to prevent the bogie from tilting or sliding during the cleaning process. By lifting on both sides, the lifting platform 260 helps to disperse the weight of the bogie and reduce the instability caused by the center of gravity shift. The design of the lifting platform 260 makes it more convenient for the operator to place and remove the bogie, especially when the bogie is heavy or large in size.

[0036] When the bogie is placed on the lifting platform 100, the lifting platform 260 supports the bogie from both sides to ensure that the bogie remains horizontal and stable during the laser cleaning process. When the lifting platform 100 performs the lifting operation, the lifting platform 260 moves with the lifting platform to maintain the support function for the bogie and ensure the stability of the bogie during the entire cleaning process.

[0037] In some embodiments, the limiting frame 210 is a slot-shaped seat. The design of the slot-shaped seat allows the limiting frame 210 to be closely matched with a specific part of the guide rail 211 or the co-rotating twin screws 230 to provide precise positioning.

[0038] In some embodiments, an electric slide rail 310 is disposed on the top of the base 300 , and the bottom of the positioner 400 is adapted to the electric slide rail 310 and is slidably connected thereto.

[0039] The electric slide 310 allows the positioner 400 to move freely on the base 300, providing greater operating space and flexibility, so that the positioner can be easily adjusted to the desired position. The electric slide 310 system is usually equipped with a precise position feedback device, such as an encoder, to ensure that the moving position of the positioner 400 can be accurately controlled to meet high-precision cleaning requirements.

[0040] Reference Figure 4 The bogie laser cleaning equipment includes the fixed tooling, a workstation 600 and at least one laser cleaning robot 500; the fixed tooling is arranged in the middle of the workstation 600, and the laser cleaning robot 500 is arranged on the side of the workstation 600.

[0041] Placing the fixed tool in the middle of the workstation 600 and the laser cleaning robot 500 on the side helps optimize the use of the workspace, making the equipment layout more compact and improving production efficiency. This layout allows the operator to easily approach the laser cleaning robot 500 from the side for operation and monitoring. The structural design of the fixed tool reduces the safety risks of the operator during the laser cleaning process, especially when handling large or heavy bogies. The fixed tool can ensure the stability and safety of the operation.

[0042] The fixture is installed in the middle of the workstation 600 as the main support and positioning device for the bogie. It is responsible for stably fixing the bogie to ensure its accurate position during the laser cleaning process. The laser cleaning robot 500 is installed on the side of the workstation 600. This position allows the robot's laser head to be flexibly moved to any position of the bogie on the fixture for cleaning.

[0043] In some embodiments, the bottom of the laser cleaning robot 500 is slidably provided with a linear slide 510, and the linear slide 510 is provided on the side of the workstation 600. The linear slide 510 is fixed on the side of the workstation 600 to provide a stable moving path for the laser cleaning robot. Through the rapid movement of the linear slide 510, the laser cleaning robot 500 can move from one cleaning position to another in a short time, thereby improving the overall efficiency of the cleaning operation.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
