[0002] As an important carrier for recording key information about bearings, the clarity and legibility of the information on the surface of railway bearing marking plates are directly related to the safe operation and maintenance efficiency of the railway system. At present, the railway industry still generally uses traditional mechanical grinding methods to remove rust from bearing marking plates.

[0003] For example, Chinese patent CN203765429U discloses a rust removal machine for railway passenger car axle box accessories. The dustproof ring grinding head is lowered by a cylinder and rubs the upper surface of the dustproof ring to remove the rust. The same method is used for rust removal of end covers. Although mechanical grinding and rust removal is simple to operate, it can easily damage the substrate of the marking plate while removing the rust layer, resulting in permanent damage to important information. Utility Model Content

[0004] This invention provides a rust removal device for bearing signboards. The laser beam acts on the rust layer in a non-contact manner, without causing additional physical pressure or scratches to the signboard, thus avoiding damage to the signboard substrate.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figures 1 to 4 As shown, a bearing marking plate rust removal device according to an embodiment of the present invention includes a frame 1, a worktable 2 on one side of the frame 1, and an adjustment component 3 and a laser component 4 above the worktable 2. Figure 5 As shown, the laser assembly 4 includes a mounting cylinder 41 and a laser 42. The laser 42 is disposed inside the mounting cylinder 41. The mounting cylinder 41 is connected to the adjustment assembly 3, and the adjustment assembly 3 drives the mounting cylinder 41 to move.

[0020] like Figure 1 As shown, when rust removal is required, the wheelset 100 and the marking plate 200 are placed on one side of the bearing marking plate rust removal device, the laser component 4 is aligned with the marking plate 200, and the laser 42 is started to perform rust removal after the distance between the laser component 4 and the marking plate 200 is adjusted to the correct position using the adjustment component 3.

[0021] This embodiment uses laser rust removal to clean the signboard 200. The laser beam acts on the rust layer in a non-contact manner, and the laser energy is rapidly converted into heat energy, instantly vaporizing and removing the rust layer. The rust removal task can be completed in a very short time without causing additional physical pressure or scratches to the signboard 200. The adjustment component 3 adjusts the distance between the laser 42 and the signboard 200 by driving the mounting cylinder 41 to move, ensuring that the laser 42 removes rust from the signboard 200 at a suitable distance, removing only the rust layer and maintaining the clarity and integrity of the markings.

[0022] like Figure 3As shown, the adjustment assembly 3 includes a guide rail 31, a drive member 32, a lead screw (not shown in the figure), and a sliding seat 33. The guide rail 31 is disposed on the surface of the worktable 2. The drive member 32 is disposed at one end of the guide rail 31 and connected to the lead screw. The lead screw is disposed inside the guide rail 31 and passes through the sliding seat 33. The sliding seat 33 is slidably connected to the guide rail 31.

[0023] In this embodiment, the driving component 32 is a motor. When the driving component 32 rotates the lead screw, the sliding seat 33 connected to the lead screw moves along the lead screw. Since the laser component 4 has a certain volume and weight, in order to ensure that the sliding seat 33 remains stable when moving, the sliding seat 33 is slidably connected to the guide rail 31.

[0024] like Figure 6 As shown, a first displacement sensor 34 is provided at the bottom of the sliding seat 33, and a second displacement sensor 35 is provided on the surface of the guide rail 31 through the mounting bracket 36. The first displacement sensor 34 and the second displacement sensor 35 are arranged opposite to each other.

[0025] In this embodiment, the first displacement sensor 34 can move with the sliding seat 33, while the second displacement sensor 35 is fixed on the surface of the guide rail 31. The change in distance between the first displacement sensor 34 and the second displacement sensor 35 corresponds to the displacement of the laser component 4, thereby enabling the monitoring of the position of the laser component 4.

[0026] The first displacement sensor 34 and the second displacement sensor 35 are inductive sensors, capacitive sensors, or photoelectric sensors.

[0027] Inductive displacement sensors use changes in inductance to measure changes in an object's position. They typically consist of a fixed coil and a movable coil. When the movable coil moves closer to or further away from the fixed coil, the inductance of the fixed coil changes. By measuring the changed inductance, the change in the object's position can be determined.

[0028] A capacitive displacement sensor measures changes in an object's position by detecting changes in capacitance. It typically consists of two parallel plates, one of which is movable. As the movable plate moves closer to or further away from a fixed plate, the capacitance between the two plates changes. By measuring this change in capacitance, the change in the object's position can be determined.

[0029] Photoelectric displacement sensors use the reflection and transmission of light to measure changes in an object's position. They typically consist of a light source, a receiver, and a movable reflector. When the reflector moves, the reflected light signal changes. By measuring this changing light signal, the change in the object's position can be determined.

[0030] like Figure 5As shown, the laser assembly 4 also includes a mounting box 43, which is connected to one side of the mounting cylinder 41 via a fixing cylinder 44. The mounting box 43 contains a galvanometer (not shown in the figure). The galvanometer is a core component for high-precision beam control in the laser system. Its core function is to guide and position the laser beam by quickly and accurately adjusting the angle of the reflector, thereby meeting the requirements for beam movement speed, trajectory accuracy, and scanning range, and better removing rust from the marking plate 200.

[0031] Furthermore, a field lens 45 is provided on one side surface of the mounting box 43. The field lens 45 is a key optical element in the laser assembly 4 that is used in conjunction with the galvanometer. Its core function is to receive the laser beam deflected by the galvanometer, focus it onto the surface of the marker plate 200, and define the effective scanning range of the laser, thereby solving the problems of laser beam divergence and limited focusing range after the galvanometer is deflected.

[0032] like Figure 5 and Figure 6 As shown, the mounting box 43 has heat dissipation holes (not shown in the figure) at both the top and bottom. The mounting box 43 has heat dissipation fins 431 inside, with the ends of the fins located within the heat dissipation holes. By providing the heat dissipation fins 431 and heat dissipation holes, the heat generated inside the mounting box 43 can be quickly released to the outside, improving the reliability of the laser assembly 4.

[0033] like Figure 2 and Figure 3 As shown, the frame 1 includes a support frame 11 and a support plate 12. Multiple support frames 11 are connected by connecting blocks 13, and the support plate 12 is disposed on the surface of the support frame 11. The frame 1 has a simple structure and is easy to assemble. By selecting support frames 11 of different sizes, the overall size of the frame 1 can be flexibly adjusted to better meet actual operational needs.

[0034] Furthermore, a cooling assembly 5 is provided inside the frame 1. The cooling assembly 5 is connected to the mounting cylinder 41 via a connecting pipe (not shown in the figure), which is used to supply cooling medium to the interior of the mounting cylinder 41. The laser 42 generates heat during operation, and cooling the laser 42 is essential for its normal operation. In this embodiment, the cooling assembly 5 supplies cooling medium to the interior of the mounting cylinder 41, which effectively removes the heat generated by the laser 42 and prevents the laser 42 from overheating.

[0035] Specifically, in this embodiment, the cooling medium is air. Using air as the cooling medium is convenient and low-cost. The cooling component 5 continuously blows air into the interior of the mounting cylinder 41, and the heated air flows out through the pores on the surface of the mounting cylinder 41, carrying away the heat.

[0036] like Figure 1As shown, the bottom of the frame 1 is provided with a foot 6, which includes a support rod 61, a foot cup 62, and a pad 63. The top of the support rod 61 is threaded to the support frame 11, and the bottom of the support rod 61 is connected to the foot cup 62. The pad 63 is located at the bottom of the foot cup 62. By turning the support rod 61, the height of the frame 1 and the worktable 2 can be adjusted, thereby adjusting the laser assembly 4 to a suitable height to align with the marking plate 200.

[0037] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
