Description

Technical Field

[0001] This utility model relates to the field of magnetic particle inspection of wheelsets and axles, and more specifically, to an automatic magnetic particle inspection device for wheelsets and axles. Background Technology

[0002] Axles are critical components used to connect and support rotating parts, commonly found in various equipment and machinery. Some axles connect wheels, transmit power, and support the weight of vehicles, while others play a role in connecting and supporting rotating components in various mechanical devices. Internal defects in axles can seriously jeopardize the safety and reliability of equipment and systems. Internal defects can reduce the effective cross-sectional area of ​​the axle, thereby reducing its load-bearing capacity and strength. This may cause the axle to be unable to withstand normal stresses and loads during operation, leading to breakage and failure. Severe internal defects in axles can cause wheels to detach. This situation is extremely dangerous because a detached wheel can cause the vehicle to lose control, threatening the safety of personnel.

[0003] Magnetic particle testing of wheelsets or axles is a non-destructive testing technique used to detect internal defects in wheelsets and axles to ensure their safety and reliability. Existing magnetic particle testing setups for wheelsets or axles require manual control of the probe's position, resulting in low automation and low testing efficiency. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] like Figure 1-4As shown, in the first embodiment of the automatic magnetic particle inspection equipment for wheelsets and axles of this utility model, the inspection equipment 10 includes a first vertical beam 11, a second vertical beam 12, a crossbeam 13 fixedly connected to the top of the first vertical beam 11 and the second vertical beam 12, a lifting beam 14 movably mounted on the first vertical beam 11 and the second vertical beam 12, a first driving component mounted on the first vertical beam 11 or the second vertical beam 12 for driving the lifting beam 14 to move up and down, a first guide rail 15 mounted on the top of the lifting beam 14 along the length direction of the lifting beam 14, a first slider 17 slidably mounted on the first guide rail 15, and a component fixedly mounted on the first slider 17. The first movable frame 19 on the 7, the second drive assembly disposed on the first movable frame 19 for driving the first movable frame 19 to move along the first guide rail 15, the second guide rail 16 disposed at the bottom of the lifting beam 14 along the length direction of the lifting beam 14, the second slider 18 slidably disposed on the second guide rail 16, the second movable frame 20 fixedly mounted on the second slider 18, the third drive assembly disposed on the second movable frame 20 for driving the second movable frame 20 to move along the second guide rail 16, the first detection probe 21 mounted on the first movable frame 19, and the second detection probe mounted on the second movable frame 20.

[0022] When using the automatic magnetic particle inspection equipment 10 for wheelsets and axles of this invention, the first drive assembly moves the lifting beam 14 to a height position corresponding to the workpiece to be inspected. The second drive assembly moves the first moving frame 19 and the first inspection probe 21 located on the first moving frame 19 to the vicinity of the workpiece to be inspected. The third drive assembly moves the second moving frame 20 and the second inspection probe located on the second moving frame 20 to the vicinity of the workpiece to be inspected. The first and second inspection probes are used to perform flaw detection on the workpiece. After the inspection is completed, the automatic inspection equipment 10 is restored to its initial state by the first, second, and third drive assemblies. By using the automatic inspection equipment 10 of this application, the movement of the first and second inspection probes can be automatically controlled, improving the efficiency of flaw detection.

[0023] It is understood that there can be multiple first movable frames 19 and second movable frames 20 in this application, and the number of first detection probes 21 and second detection probes disposed on the first movable frames 19 and second movable frames 20 corresponds one-to-one.

[0024] Specifically, the first drive assembly includes a vertical lead screw 22 rotatably mounted on the second vertical beam 12, a first servo motor 23 mounted on the first vertical beam 11 or the second vertical beam 12 for driving the vertical lead screw 22 to rotate, a nut sleeved on the vertical lead screw 22 and screwed to the vertical lead screw 22, and the second end of the lifting beam 14 is fixedly connected to the nut.

[0025] Furthermore, a first vertical slide rail 24 is fixedly provided on the first vertical beam 11, and a second vertical slide rail 25 is fixedly provided on the second vertical beam 12. A first sliding block 26 that can slide on the first vertical slide rail 24 is provided, and a second sliding block 27 that can slide on the second vertical slide rail 25 is provided. The first end of the lifting beam 14 is fixedly connected to the first sliding block 26, and the second end of the lifting beam 14 is fixedly connected to the second sliding block 27.

[0026] When the first servo motor 23 rotates, it drives the vertical lead screw 22 to rotate, which in turn drives the nut to move up and down on the vertical lead screw 22. During this process, the first sliding block 26 and the second sliding block 27 move on the first vertical slide rail 24 and the second vertical slide rail 25 respectively, thereby driving the lifting beam 14 to rise and fall.

[0027] Understandably, the vertical lead screw 22 is arranged parallel to the first vertical slide rail 24 and the second vertical slide rail 25.

[0028] In this embodiment, as Figure 3 As shown, the second drive assembly includes a second servo motor 28 fixedly mounted on the first moving frame 19, a first gear 29 mounted on the output shaft of the second servo motor 28, and a first rack 30 fixedly mounted on the lifting beam 14 and meshing with the first gear 29. The first rack 30 is arranged along the length direction of the lifting beam 14.

[0029] When it is necessary to move the first moving frame 19 and the first detection probe 21 laterally along the lifting beam 14, the second servo motor 28 can be controlled to drive the first gear 29 to rotate. The first gear 29 meshes with the first rack 30, thereby driving the first moving frame 19 and the first detection probe 21 to move along the first guide rail 15 through the cooperation of the first gear 29 and the first rack 30. It can be understood that the first guide rail 15 is set parallel to the first rack 30.

[0030] Furthermore, to facilitate the insertion of the first detection probe 21 into the workpiece for detection, a first telescopic cylinder 34 is fixedly mounted on the first movable frame 19 along the length direction of the first movable frame 19. The first detection probe 21 is mounted on the first mounting member 35, and the first mounting member 35 is fixedly mounted on the extended end of the first telescopic cylinder 34.

[0031] After the first moving frame 19 is moved to face the workpiece, the first telescopic cylinder 34 can be activated to extend and insert the first detection probe 21 into the workpiece for flaw detection.

[0032] Similarly, such as Figure 3As shown, the third drive assembly includes a third servo motor 31 fixedly mounted on the second moving frame 20, a second gear 32 mounted on the output shaft of the third servo motor 31, and a second rack 33 fixedly mounted on the lifting beam 14 and meshing with the second gear 32. The second rack 33 is arranged along the length direction of the lifting beam 14.

[0033] When it is necessary to move the second moving frame 20 and the second detection probe laterally along the lifting beam 14, the third servo motor 31 can be controlled to drive the second gear 32 to rotate. The second gear 32 meshes with the second rack 33, thereby driving the second moving frame 20 and the second detection probe to move along the second guide rail 16 through the cooperation of the second gear 32 and the second rack 33. It can be understood that the second guide rail 16 and the second rack 33 are arranged parallel to each other.

[0034] Furthermore, to facilitate the insertion of the second detection probe into the workpiece for detection, a second telescopic cylinder 36 is fixedly mounted on the second movable frame 20 along its length. The second detection probe is mounted on a second mounting component, which is fixedly mounted on the extended end of the second telescopic cylinder 36.

[0035] After the second moving frame 20 is moved to face the workpiece, the second telescopic cylinder 36 can be activated to extend and insert the second detection probe into the workpiece for flaw detection.

[0036] Specifically, such as Figure 4 As shown, both the first detection probe 21 and the second detection probe include at least one illuminance probe 37, at least one black light 38, at least one camera 40, and at least one laser 39.

[0037] Furthermore, to facilitate the fixed installation of the testing equipment 10, a first fixed base 41 for fixing the first vertical beam 11 is fixed at the bottom, and a second fixed base 42 for fixing the second vertical beam 12 is fixed at the bottom.

[0038] Furthermore, in this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," "stacked," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
