AI Technical Summary
In the existing technology, when the bearing roller flaw detector sprays magnetic suspension liquid on rollers of different models, the fixed distance between the spray head and the spraying station leads to differences in the spraying effect, which affects the test results.
A magnetic suspension spraying mechanism was designed, including a slide rail, a slide base, an electrode head, and a spray head. The spray head can be flexibly adjusted through the slide base drive assembly and the lead screw drive assembly to adapt to rollers with different outer diameters and ensure consistent spraying distance.
Ensure that the distance between the sprayer and the roller circumference remains consistent during each spraying process to ensure the effectiveness of the test.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of flaw detection technology, and in particular to a magnetic suspension spraying mechanism applied in a bearing roller flaw detector. Background Technology
[0002] Rail transit systems such as trains, subways, and light rail are becoming increasingly important in the national economy due to their advantages of large capacity and high speed, and the safety of rail transit is receiving increasing attention. During rail transit operation, wheel bearings are critical components. Wheel bearings mainly consist of an inner ring, an outer ring, and rollers located between the inner and outer rings. To ensure safe vehicle operation, each component of the wheel bearing must undergo flaw detection during the manufacturing process to ensure that each component meets quality requirements. Currently, the inspection of rollers on wheel bearings mainly uses magnetic particle testing. First, the rollers are magnetized, then a magnetic suspension is sprayed onto them, and finally, the traces of magnetic powder on the rollers are manually inspected to determine whether the rollers meet quality requirements.
[0003] In related technologies, when the same equipment sprays magnetic suspension liquid onto rollers of different models, the fixed distance between the spray head and the spray station can lead to differences in the spraying effect, which in turn affects the test results.
[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a magnetic suspension spray mechanism for use in bearing roller flaw detectors to solve the above problems. Utility Model Content
[0005] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a magnetic suspension spraying mechanism for use in bearing roller flaw detectors.
[0006] To achieve the above and other related objectives, the technical solution provided by this utility model is: a magnetic suspension spray mechanism applied in a bearing roller flaw detector, comprising a base, a slide rail and a liquid accumulation tank on the base, the liquid accumulation tank being located on the middle side of the slide rail, a slide block one and a slide block two on the slide rail and on both sides of the liquid accumulation tank, an electrode head one and a spray head one on the slide block one, and an electrode head two and a spray head two on the slide block two, the electrode head one and the electrode head two being arranged opposite to each other to form a magnetization assembly for clamping and magnetizing the roller, the spray head one being arranged corresponding to the electrode head one, and the spray head two being arranged corresponding to the electrode head two; further comprising a spray head three, the spray head three being arranged corresponding to the circumferential surface of the roller clamped and fixed by the magnetization assembly, the spray head three being driven by a lead screw transfer module one to approach or move away from the circumferential surface of the roller clamped and fixed by the magnetization assembly.
[0007] A preferred technical solution is as follows: the first slide is provided with a drive assembly for driving the first electrode head to rotate, and the second slide is provided with a drive assembly for driving the second electrode head to rotate.
[0008] The preferred technical solution is as follows: the base is provided with a second lead screw transfer module and a third lead screw transfer module. The second lead screw transfer module is used to drive the first slide block to slide on the slide rail, and the third lead screw transfer module is used to drive the second slide block to slide on the slide rail.
[0009] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:
[0010] The magnetic suspension spraying mechanism provided by this utility model for use in bearing roller flaw detectors has an end face spraying structure that corresponds to the electrode head structure that clamps and fixes the end face of the roller. Its peripheral spraying structure can adapt to rollers with different outer diameters, ensuring that the distance between the spraying structure and the peripheral surface of the roller is consistent during each spraying process, thereby ensuring the detection effect.

[0013] Please see Figure 1 It should be noted that in the description of this utility model, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. These terms are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. The terms "horizontal," "vertical," and "suspended," etc., do not indicate that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0014] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly.
