DETAILED DESCRIPTION

[0030] The application is further illustrated below in conjunction with the accompanying drawings and examples.

[0031] The high-speed rail axle is straightened and needs to be marked with a steel stamp number on the surface of the axle to mark and distinguish different types and different production times of high-speed rail axles.

[0032] A containing groove is formed on the surface of the high-speed rail axle straightening equipment, and the steel stamping device is placed in the containing groove to complete the steel stamping marking on the high-speed rail axle after straightening. The above operation simplifies the process of high-speed rail axle machining and improves the efficiency of high-speed rail axle machining.

[0033] In the operation process of the existing steel stamping marking, the staff needs to hold the steel stamping device outside and insert it into the containing groove, and the marking on the surface of the high-speed rail axle is completed in the extrusion process. In order to smoothly insert the steel stamping device into the containing groove, the size of the inside of the containing groove is slightly larger than the size of the outside of the steel stamping device, and the steel stamping device has a certain activity gap to facilitate the insertion of the steel stamping device. However, due to the existence of a certain space, the steel stamping device is in an unstable state in the containing groove, which affects the stability of the overall structure and the steel stamping marking on the surface of the high-speed rail axle.

[0034] Referring to the accompanying Figure 1 -Appendix Figure 10 The high-speed rail axle surface stable marking equipment comprises a straightening base 100, a plurality of straightening blocks 110 for straightening the axle 200 are installed on the upper end of the straightening base 100, and the plurality of straightening blocks 110 can extrude the axle 200 in the process of approaching each other to realize the straightening machining of the axle 200.

[0035] It also comprises a steel stamping device 300, a containing groove for accommodating the steel stamping device 300 is opened on the inner side wall of the straightening block 110, and a control device 400 connected with the steel stamping device 300 is also installed on the upper end of the straightening base 100. The control device 400 comprises a position limiting assembly 420 connected with the steel stamping device 300 and a position control device 410 for controlling the linear movement of the steel stamping device 300, and the steel stamping device 300 is driven into the containing groove by the position control device 410; the steel stamping device 300 can move with the straightening block 110 towards the axle 200 to perform steel stamping on the surface of the axle 200; during the straightening of the axle, the steel stamping device 300 is controlled to move out of the containing groove, at this time the steel stamping device 300 does not move synchronously with the straightening block 110, at this time it does not affect the normal straightening machining of the axle 200.

[0036] The inner wall of the accommodating groove is provided with a locking assembly 430. After the steel stamping device 300 reaches the predetermined position, the locking assembly 430 is controlled to be in a locked state. By arranging the locking assembly 430, the stability of the steel stamping device 300 in the accommodating groove can be ensured. The steel stamping device 300 is fixed by the locking assembly 430, so as to avoid the steel stamping device 300 from separating from the accommodating groove, and the stability of the steel stamping device 300 in the steel stamping process is ensured. At the same time, the above-mentioned equipment can replace manual holding of the steel stamping device 300, so as to automatically mark after the axle straightening machining, and the efficiency of the axle machining is further improved.

[0037] Specifically, the preferred locking assembly 430 includes a first locking telescopic rod 431 and a second locking telescopic rod 432. The first locking telescopic rod 431 is located at the end of the moving path of the steel stamping device 300. The second locking telescopic rod 432 is arranged in the extension direction intersecting with the moving path of the steel stamping device 300. The first locking telescopic rod 431 and the second locking telescopic rod 432 are communicated through a conveying pipeline with a built-in control valve.

[0038] During the movement of the steel stamping device 300 towards the inside, the first locking telescopic rod 431 can be extruded by the steel stamping device 300. The control oil in the first locking telescopic rod 431 enters the second locking telescopic rod 432. The second locking telescopic rod 432 extruded can clamp and limit the steel stamping device 300 from both sides, so as to ensure the stability of the steel stamping device 300 in the accommodating groove, and ensure the stability of the steel stamping device 300 in the steel stamping process.

[0039] During the movement of the steel stamping device 300, the control valve is adjusted to be in an open state, so as to extrude the control oil in the first locking telescopic rod 431 into the second locking telescopic rod 432 to complete the clamping and limiting. At the same time, after the steel stamping device 300 moves to the predetermined position, the control valve is closed. At this time, the second locking telescopic rod 432 can stably clamp and limit the steel stamping device 300, so as to prevent the steel stamping device 300 from separating. At the same time, through the above structure design, the position of the steel stamping device 300 can be positioned. A predetermined force is applied to push the steel stamping device 300 to complete the positioning and clamping of the steel stamping device 300. Compared with the traditional locking structure, the limiting structure is simple and reliable, and meets the needs of the steel stamping on the surface of the axle.

[0040] The steel stamping device 300 includes a plurality of steel stamping blocks 340 and an accommodating box 310 for accommodating the plurality of steel stamping blocks 340. The first side wall of the accommodating box 310 is fixedly connected with a connecting workpiece 330 and a control device 400.

[0041] The outer surface of the stamped block 340 has specific numbers. By arranging multiple stamped blocks 340, different codes can be completed. By setting the connecting workpiece 330, the stamping device 300 can be installed and positioned from the outside, allowing the stamping device 300 to extend into the predetermined position in the receiving groove, ensuring the normal stamping of the axle 200 surface.

[0042] The second side wall of the receiving box 310 is fixed with a locking block 320 extending outward, and the cross section of the receiving groove is T-shaped to match the locking block 320.

[0043] By setting the locking block 320, the overall structure of the stamping device 300 can be further limited, ensuring the stability of the overall structure's positioning. The size of the receiving groove is designed to match the locking block 320, guiding the overall structure of the stamping device 300 so that it can accurately enter the receiving groove, ensuring the accurate positioning of the stamping device 300. At the same time, as the straightening block 110 deflects inward, the locking block 320 tilts inward, and the locking block 320 abuts against the upper end of the inner wall of the receiving groove, further preventing the stamping device 300 from moving out of the receiving groove, thus ensuring the stability of the stamping device 300 during the stamping process.

[0044] Traditional methods of manually positioning the stamp box from the outside using connecting rods or using other mechanical equipment for assisted gripping are difficult to adapt to the movement trajectory of the straightening equipment (the movement trajectory of the straightening block 110 is arc-shaped). A simple flexible positioning structure cannot provide good support during the transfer of the stamp box, and a simple rigid positioning structure is affected by impact forces from different directions, impacting the strength and stability of the local structure.

[0045] To solve the above problems, the limiting component 420 is designed to have a rigid state and a non-rigid state. After the position control device 410 pushes the stamping device 300 into the receiving groove, it controls the limiting component 420 to be in a non-rigid state to complete the stamping on the surface of the axle 200.

[0046] When the limiting component 420 is in a non-rigid state, the stamping device 300 can move synchronously with the straightening block 110 to complete the stamping operation on the surface of the axle 200. During the stamping process, the stamping device 300 is in a non-rigid state, and the impact generated by the straightening block 110 will not affect the limiting component 420, ensuring the normal and continuous use of the overall structure. During the process of removing the stamping device 300, the limiting component 420 is controlled to be in a rigid state. During this process, the stamping device 300 can be removed normally, allowing the stamping device 300 to be in the rated position for standby, ensuring that the stamping device 300 can correctly enter the receiving groove next time, and that the overall structure can remain stable during the stamping process without affecting the straightening of the axle 200.

[0047] The limiting component 420 includes a limiting sleeve 421. A limiting telescopic rod 422 is provided on the inner wall of the limiting sleeve 421. The telescopic end 4222 of the limiting telescopic rod 422 is connected to the stamping device 300. The base end 4221 of the limiting telescopic rod 422 is connected to the inner wall of the limiting sleeve 421. An adjusting component is provided on the inner wall of the limiting sleeve 421. The base end 4221 of the limiting telescopic rod 422 and the inner wall of the limiting sleeve 421 can be connected via a universal joint. The adjusting component controls the rigid and non-rigid states. When the stamping device 300 is stamping, the straightening block 1... 10 drives the stamping device 300 to move outward along an arc-shaped trajectory. During this process, the limiting telescopic rod 422 extends and deflects at a predetermined angle. The stamping device 300 can move synchronously to complete the stamping on the surface of the axle 200. During the reset process, the limiting telescopic rod 422 resets along the opposite trajectory. At this time, the limiting telescopic rod 422 returns to its initial state, and the control adjustment component is in a rigid state. This can achieve the limiting and fixing of the limiting telescopic rod 422 and the outer stamping device 300, ensuring that they are in a rigid and stable state.

[0048] The adjustment assembly includes multiple deformable adjustment parts 4211, which are arranged circumferentially around the limiting telescopic rod 422. The adjustment parts 4211 have rigid and non-rigid states. When the limiting telescopic rod 422 is in a rigid state, it can be limited and fixed from multiple directions. When the limiting telescopic rod 422 is in a non-rigid state, it can move freely. Through the above structural design, the limiting telescopic rod 422 can be stably supported while having sufficient free movement space to meet the control requirements.

[0049] The position control device 410 includes an electric guide rail 411 and an electric slider 412. An elastic air pump assembly 500 is provided on the moving path of the electric slider 412. The surface of the stamping device 300 is provided with an air outlet that communicates with the air pump assembly 500. During the linear movement of the electric slider 412 controlled by the electric guide rail 411, the air pump assembly 500 can be squeezed. After being squeezed, the air pump assembly 500 can discharge the internal gas. The gas is discharged from the air outlet on the surface of the stamping device 300, which can clean the surface of the stamping device 300 and prevent the accumulation of oxides from the high-temperature axle 200 on the surface of the stamping device 300, thus ensuring the normal operation of the stamping device 300 in subsequent stamping.

[0050] The vent is preferably located at the top and extends downwards to exhaust gas. The gas acts directly on the surface of the stamped block 340. The oxides are subjected to the combined effects of gravity and gas force, which can clean the surface of the stamped block 340 from top to bottom, thus minimizing the residue of oxides on the surface of the stamped block 340.

[0051] The air pumping assembly 500 includes a limiting plate 510. An elastic pumping air bag 520 is installed between the limiting plate 510 and the electric slider 412. The pumping air bag 520 is connected to two pumping pipes with built-in one-way valves. The first pumping pipe is connected to the air outlet. During the return stroke of the limiting sleeve 421 (removing the stamping device 300 from the receiving groove), the air pumping assembly 500 can be squeezed to realize the blowing process. During the process of the limiting sleeve 421 controlling the stamping device 300 to move towards the receiving groove, the air pumping assembly 500 resets under its own elastic force and can return to the inflated state. During this process, it can draw in external gas to prepare for the next air pumping.

[0052] The present invention will be further described below in conjunction with the processing method.

[0053] The method for surface stabilization marking of high-speed train axles, using the aforementioned surface stabilization marking equipment, includes the following steps:

[0054] S1. The stamping device 300 is driven by the position control device 410 to be offset from the receiving groove, and the straightening process of the axle is completed by multiple straightening blocks 110. During the continuous squeezing process of the multiple straightening blocks 110 towards the inside, the axle 200 is controlled to rotate around its own axis, and the straightening process of the axle 200 is completed.

[0055] S2. After the axle straightening process is completed, the stamping device 300 is driven into the receiving groove by the position control device 410. During this process, the control limit component 420 is in a rigid state, which allows the stamping device 300 to enter the predetermined position in the receiving groove accurately and stably.

[0056] S3. When the stamping device 300 reaches the predetermined position, the locking component 430 is locked. The stamping device 300 and the straightening block 110 move synchronously to complete the marking on the axle surface. During this process, the stamping device 300 is pressed against the surface of the axle 200 to complete the marking on the axle surface. At this stage, the control limiting component 420 is in a non-rigid state, which allows the stamping device 300 to move synchronously with the straightening block 110, avoiding damage to the outer limiting component 420 and other structures.

[0057] 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 within the protection scope of the present invention.
