Technical Field

[0001] This utility model relates to the field of flaw detection technology for ferromagnetic parts, and in particular to a miniature magnetic yoke magnetic particle flaw detector. Background Technology

[0002] The miniature magnetic yoke flaw detector is a small magnetic particle flaw detector used for non-destructive testing of ferromagnetic parts. It can detect surface and shallow surface latent cracks and defects of the tested parts without damaging the material or affecting the performance of the tested parts. The magnetization principle is to use a magnetizing coil to generate a magnetic field at both ends of the contact surface between the magnetic yoke and the tested parts to detect cracks and defects within the range of the two magnetic yoke end faces. Since magnetic yoke flaw detectors are mostly used to inspect welds of large structures, they need to be portable and easy to operate. Therefore, the magnetic yoke flaw detectors made need to be as small as possible and easy to hold.

[0003] Traditional types of equipment suffer from problems such as low detection accuracy, poor stability, inconvenience of use, and limited functionality due to a lack of stable support and flexible adjustment structures, dedicated fixed components, convenient power supply design, and functional expansion interfaces, making them difficult to adapt to complex detection scenarios.

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figure 1-4This utility model discloses a miniature magnetic yoke magnetic particle flaw detector, comprising: a main body 1 and a detection component. Two mounting blocks 7 are provided on one side of the outer surface of the main body 1, and a fixing block 15 is fixedly connected between each of the two mounting blocks 7. The two mounting blocks 7 provide a stable mounting carrier for the fixing blocks 15, allowing the fixing blocks 15 to be firmly connected to the main body 1, laying the foundation for the subsequent installation of components such as adjusting bolts 16. Adjusting bolts 16 are detachably connected between the two fixing blocks 15 via adjusting nuts 14. The adjusting bolts 16 can be adjusted in position between the two fixing blocks 15, and the adjusting nuts 14 can fix the adjusting bolts 16 in the desired position, enabling flexible adjustment of the spacing between related components. An installation groove 8 is provided on the side of the fixing blocks 15 away from the fixing blocks 15. The installation groove 8 provides installation space for other supporting components, facilitating the precise assembly of subsequent components with the fixing blocks 15 and ensuring the integrity of the overall structure of the equipment. The inner surface of the mounting block 7 is fixedly connected to a positioning post 9, which plays a positioning and guiding role in the mounting groove 8, ensuring that the subsequent strap connecting block 10 can be accurately installed and maintain a stable position. The outer surface of the positioning post 9 is rotatably connected to the strap connecting block 10, which can rotate around the positioning post 9, making it convenient to fix the main body of the equipment 1 in a suitable detection position by strapping, thus improving the stability of the equipment during the detection process. The lower surface of the mounting block 7 is provided with an output connection port 12 and a module series connection port 13 on the left and right sides, respectively. The output connection port 12 is used to connect the power cord 5 to realize power output, and the module series connection port 13 is used to realize the series connection of multiple equipment modules, expanding the detection function and range of the equipment. The front surface of the mounting block 7 is fixedly connected to a battery mounting slide 11, which provides a dedicated mounting slide for the battery, facilitating the quick installation and removal of the battery and ensuring that the equipment can obtain power supply in a timely manner.

[0019] The fixing block 15 houses a power control module, which regulates the power supply to the equipment, including current and power switch settings, ensuring stable operation of all components under appropriate power conditions. The output connection port 12 and the module series connection port 13 are positioned parallel to each other. This parallel arrangement prevents interference when installing connecting cables and facilitates quick identification and connection by operators, improving operational convenience. The number of output connection ports 12 corresponds to the number of mounting blocks 7, ensuring that each mounting block 7 can achieve independent power output through the output connection port 12, guaranteeing the independence and stability of power supply to each part of the equipment. The fixing blocks 15 are symmetrically arranged on the side walls of the mounting blocks 7. The symmetrically arranged fixing blocks 15 on the upper and lower sides ensure even force distribution on both sides of the mounting block 7, improving the stability of the connection between the mounting block 7 and the main body 1 of the equipment. This also guarantees balance during subsequent adjustment of the adjusting bolts 16. The two fixing blocks 15 are staggered, allowing for a more rational arrangement of the adjusting bolts 16 within a limited space, preventing components from obstructing each other, improving the convenience of adjustment operations, and optimizing the overall compactness of the equipment structure. The outer surfaces of the adjusting nut 14 and the fixing blocks 15 abut against each other, ensuring that the adjusting nut 14 can tightly fix the adjusting bolts 16, preventing the adjusting bolts 16 from shifting position due to vibration or other factors during equipment operation, and ensuring the stability of the equipment after adjustment. The battery mounting slide 11 is located on the front surface of the mounting block 7. The centrally located position of the battery ensures a more balanced center of gravity for the entire device after installation, preventing tilting during use due to battery misalignment and improving safety. The detection component, located on the outer surface of the main body 1, includes a magnetized probe 2, a handle 3, a switch 4, a power cord 5, and a light source 6. This component is the core of the magnetic particle inspection function, with each part working collaboratively. The magnetized probe 2 generates a magnetic field, the handle 3 facilitates gripping, the switch 4 controls start / stop, the power cord 5 transmits electrical energy, and the light source 6 provides illumination. The handle 3 is fixedly attached to the upper surface of the main body 1, allowing operators to easily move or adjust the inspection position, thus improving ease of operation. For flexibility, a switch 4 is fixedly connected to the inner surface of the handle 3. Positioning the switch 4 on the inner surface of the handle 3 allows the operator to quickly access the switch while gripping the handle 3, facilitating timely control of the equipment's start and stop, improving operational efficiency and safety. Magnetized probes 2 are fixedly connected to both the left and right sides of the lower surface of the equipment body 1. These magnetized probes 2 form a uniform magnetic field in the detection area, ensuring comprehensive coverage of the part's inspection surface and improving the accuracy of flaw detection. A light source 6 is positioned between the two magnetized probes 2, directly illuminating the area inspected by the magnetized probes 2. This allows the operator to clearly observe the magnetic powder distribution in the inspection area and promptly detect defects. A power cord 5 is fixedly connected to the side wall of the equipment body 1.The power cord 5 is fixed to the side wall of the main body 1, preventing it from swinging and affecting the testing operation, while ensuring a secure connection between the power cord 5 and the main body 1. One end of the power cord 5 is detachably connected to the output connector 12, facilitating replacement and maintenance. In case of a fault, the power cord 5 can be quickly separated from the output connector 12 for replacement without affecting the normal operation of other components. The switch 4 is located in the center of the inner surface of the handle 3, allowing for convenient and quick operation regardless of whether the operator holds the handle 3 with their left or right hand, improving the versatility and ease of operation. The light source 6 is fixedly connected to the lower surface of the main body 1, ensuring its stable position during operation and preventing displacement due to equipment movement or vibration, thus guaranteeing precise alignment between the illumination area and the testing area.

[0020] Working principle: First, push the adapter battery along the slide of the battery mounting slide 11 to complete the battery installation and power the device. Then, check the power cord 5 and disconnect one end from the output connection port 12 on the lower surface of the mounting block 7 to ensure a secure connection. If the detection function needs to be expanded, multiple device modules can be connected in series through the module series connection port 13. According to the position and shape of the workpiece to be detected, the binding strap connecting block 10 rotates around the positioning post 9, and the binding strap fixes the main body 1 of the device in a suitable detection position. If the distance between the device and the workpiece needs to be adjusted, the adjusting nut 14 can be rotated to loosen it and move the adjusting bolt 16 between the two fixing blocks 15. After adjusting to the appropriate position, tighten the adjusting nut 14 to fix the adjusting bolt 16 and ensure the accurate detection position of the device. The operator holds the handle 3 on the upper surface of the main body 1 with both hands, so that the hands can naturally reach the handle. 3. Switch 4 in the middle of the inner surface of the device is pressed to start the device. The power control module in the fixing block 15 inside the device starts to work and regulates the power supply, so that the magnetized probes 2 on the left and right sides of the lower surface of the device body 1 generate a magnetic field. At the same time, the light source 6 between the two magnetized probes 2 lights up to illuminate the detection area. The operator holds the handle 3 to move the device and make the magnetized probe 2 fit against the surface of the workpiece to be detected. The magnetic powder distribution is observed through the area illuminated by the light source 6 to determine whether there are defects in the workpiece. After the detection is completed, press the switch 4 on the inner surface of the handle 3 again to turn off the device power. Disconnect the power cord 5 from the output connection port 12. If there are series-connected device modules, disconnect the connection at the module series connection port 13. Finally, remove the device body 1 from the detection position, remove the straps, take out the battery in the battery mounting slide 11, clean the device and put it away.
