Description

Technical Field

[0001] This utility model belongs to the technical field of residual magnetism detection mechanism, and in particular relates to an online automatic residual magnetism detection mechanism. Background Technology

[0002] Remanence refers to the magnetic induction intensity remaining in a ferromagnetic material after the external magnetic field is removed. A remanence detection mechanism is a device used to measure the residual magnetism in ferromagnetic materials. It measures the magnetic field strength remaining in the material after demagnetization using a measuring instrument, and evaluates whether the material meets the requirements for subsequent processing or use based on the measured remanence value.

[0003] In many industrial sectors, the residual magnetism intensity after demagnetization is subject to strict standards and specifications. For example, the American standard ASTM E1444-2011 and the Chinese aviation industry standard HB / Z 72-1998 both clearly state that the residual magnetism intensity of a workpiece after demagnetization treatment must not exceed 0.3 mT (3 Gs). However, in practice, most companies still rely on manual methods to manually test the residual magnetism of workpieces one by one using instruments. This manual testing method has many drawbacks, such as insufficient measurement accuracy, low efficiency, susceptibility to environmental interference, limited measurement range, poor repeatability, difficulty in automation, and excessively high requirements for operators. These problems are particularly prominent in scenarios requiring large-scale production and high-precision testing, greatly restricting the improvement of production efficiency and quality control. Therefore, this utility model proposes an online automatic residual magnetism detection mechanism. Utility Model Content

Through the coordinated operation of a gaussmeter and a demagnetizing device, this counting scheme avoids many drawbacks of traditional manual demagnetization, such as low measurement accuracy, low efficiency, high susceptibility to environmental influences, and poor repeatability. By using an extension rod to optimize the demagnetization effect, especially on workpieces with small L / D values, the demagnetization effect is significantly improved, and the influence of the demagnetizing field is reduced.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

Specific implementation examples:

[0026] Please see Figures 1-5 As shown, this utility model discloses an online automatic residual magnetism detection mechanism, comprising a mounting plate 1, a frame 2 fixedly connected to the top of the mounting plate 1, a guide rail 3 fixedly connected to the top of the frame 2, a slider 4 slidably connected to the top of the guide rail 3, and a mounting frame 6 fixedly connected to the top of the slider 4. A translation cylinder 5 is fixedly connected to one side of the guide rail 3, and the output end of the translation cylinder 5 is fixedly connected to the slider 4. A first lifting cylinder 7 and a second lifting cylinder 11 are fixedly connected to the inner wall of the mounting frame 6, respectively. A connecting frame 8 is fixedly connected to the output end of the first lifting cylinder 7, and the bottom end of the connecting frame 8 is fixedly connected to... There is a demagnetizing coil 9. The output end of the second lifting cylinder 11 is fixedly connected to a connector 12, and the bottom end of the connector 12 is fixedly connected to an extension rod 10. The bottom end of the extension rod 10 is located inside the demagnetizing coil 9. A gaussmeter 13 is provided on one side of the mounting bracket 6. A residual magnetism detection probe 14 is provided on the outer wall of the extension rod 10, and a connecting wire harness 15 is fixedly connected between the residual magnetism detection probe 14 and the gaussmeter 13. A fixing plate 18 is provided on one side of the mounting plate 1, and a bracket 19 is fixedly connected to the top of the fixing plate 18. A workpiece body 20 is placed on the bracket 19, and the workpiece body 20 is located at the bottom of the demagnetizing coil 9.

[0027] In the specific implementation process, the first lifting cylinder 7 and the second lifting cylinder 11 respectively drive the demagnetizing coil 9 and the extension rod 10 upward to the initial position. After the upward movement is completed, the translation cylinder 5 drives the mounting frame 6 to automatically translate to the initial position on the guide rail 3 and the slider 4, so that it drives the demagnetizing coil 9 and the extension rod 10 to the initial position, preparing for the installation of the workpiece body 20. Then, the workpiece body 20 is installed on the bracket 19 to ensure that the workpiece body 20 is firmly fixed. After the workpiece body 20 is installed, the translation cylinder 5 drives the demagnetizing coil 9 and the extension rod 10 through the mounting frame 6. The rod 10 automatically returns to the working position, ready for demagnetization. Next, the first lifting cylinder 7 pneumatically lowers the demagnetizing coil 9 to the surface of the workpiece body 20 and connects it to an alternating magnetic field. This causes the workpiece body 20 to experience alternating magnetic poles and decreasing magnetic field strength, thereby disrupting its magnetic domain arrangement and achieving demagnetization. Then, the second lifting cylinder 11 pneumatically presses the extension rod 10 against the workpiece. The extension rod 10 optimizes the demagnetization effect, especially on workpiece bodies 20 with small L / D values, by increasing the effective length of the workpiece body 20 and reducing... To mitigate the effects of the demagnetizing field and improve the demagnetizing effect, a residual magnetism detection probe 14 fixed to the side of the extension rod 10 is used to detect residual magnetism. The magnetic flux measured by the residual magnetism detection probe 14 is processed by a gaussmeter 13 and output as an analog signal, which is then fed back to the analog input module of the PLC. The PLC's internal program converts the analog signal into a digital signal and sends it to the WINCC report of the industrial control computer for recording and saving. Upper and lower limits for residual magnetism data are set in the PLC. When the residual magnetism in the feedback information exceeds the limit, the PLC will trigger an alarm to remind the operator to handle the situation promptly, and the gaussmeter 13 will display... The display circuit board is modified to a constant-on mode to prevent automatic shutdown and ensure the continuity of the detection process. The system automatically executes a decaying AC demagnetization program to gradually weaken the magnetic field and ensure that the residual magnetism of the workpiece is reduced to the minimum. After demagnetization is completed, the second lifting cylinder 11 drives the extension rod 10 and the residual magnetism detection probe 14 to rise pneumatically away from the surface of the workpiece body 20. At the same time, the first lifting cylinder 7 drives the demagnetizing coil 9 to rise pneumatically to the initial position, completing one demagnetization cycle. Then, the translation cylinder 5 drives the demagnetizing coil 9 and the extension rod 10 to automatically return to the working position, waiting for the next part.

[0028] Among them, a pair of guide rods 801 are fixedly connected to the top of the connecting frame 8, and a pair of guide tubes 802 are embedded in the outer wall of the mounting frame 6, and the top of the guide rods 801 passes through the guide tubes 802 and extends to its top.

[0029] When the first lifting cylinder 7 drives the connecting frame 8 and the demagnetizing coil 9 to move up and down, it drives the guide rod 801 to move up and down along the conductor tube 802, thereby assisting the movement of the connecting frame 8 and the demagnetizing coil 9 and keeping them in stable motion.

[0030] The mounting bracket 6 has a fixed connection to a hanging bracket 1301 on one side, and the gaussmeter 13 is inserted into the hanging bracket 1301.

[0031] The bracket 1301 enables the gaussmeter 13 to be fixedly installed and kept stable.

[0032] Among them, a pair of electric telescopic rods 16 are fixedly connected to the outer wall of the extension rod 10, and a pressing block 17 is fixedly connected to one end of each pair of electric telescopic rods 16. The inner wall of the pressing block 17 is in close contact with the outer wall of the residual magnetism detection probe 14.

[0033] When the residual magnetism detection probe 14 contacts the outer wall of the extension rod 10, a pair of electric telescopic rods 16 pull the extrusion block 17 toward the extension rod 10, extruding the residual magnetism detection probe 14 and the extension rod 10 to keep them fixed.

[0034] The bracket 19 has two pairs of connecting plates 21 fixedly connected to its outer wall, and the top of the connecting plate 21 is fixedly connected to a slide cylinder 22. The output ends of the two pairs of slide cylinders 22 are fixedly connected to clamping blocks 23, and the inner walls of the two pairs of clamping blocks 23 are in contact with the outer wall of the workpiece body 20.

[0035] Two pairs of sliding cylinders 22 drive two pairs of connecting plates 21 to move toward the workpiece body 20, causing two pairs of clamping blocks 23 to approach the workpiece body 20 and clamp and fix it, so that the workpiece body 20 remains stable during the demagnetization process.

[0036] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon.

[0038] The working principle of this utility model is as follows:

[0039] In use, the first lifting cylinder 7 and the second lifting cylinder 11 respectively drive the demagnetizing coil 9 and the extension rod 10 upward to their initial positions. After the upward movement is completed, the translation cylinder 5 drives the mounting frame 6 to automatically translate to its initial position on the guide rail 3 and the slider 4, thereby driving the demagnetizing coil 9 and the extension rod 10 to their initial positions. Then, the workpiece body 20 is mounted on the bracket 19. The two pairs of sliding rod cylinders 22 drive the two pairs of connecting plates 21 and the two pairs of clamping blocks 23 to approach the workpiece body 20 and clamp and fix it. Immediately afterwards, the translation cylinder 5 drives the demagnetizing coil 9 and the extension rod 10 to automatically return to their working positions via the mounting frame 6. At the same time, the first lifting cylinder 7 drives the demagnetizing coil 9 to pneumatically descend to the surface of the workpiece body 20, applying a demagnetizing magnetic field, and the second lifting cylinder... Cylinder 11 drives the extension rod 10 to pneumatically press against the workpiece, causing the residual magnetism detection probe 14 fixed on the side of the extension rod 10 to perform residual magnetism detection. The magnetic flux measured by the residual magnetism detection probe 14 is processed by the gaussmeter 13 and output as an analog signal, which is fed back to the analog input module of the PLC. The PLC internal program converts the analog signal into a digital signal and then sends it to the WINCC report of the industrial control computer for recording and saving. After demagnetization is completed, the second lifting cylinder 11 drives the extension rod 10 and the residual magnetism detection probe 14 to rise pneumatically away from the surface of the workpiece body 20. At the same time, the first lifting cylinder 7 drives the demagnetizing coil 9 to rise pneumatically to the initial position, completing one demagnetization cycle. Then, the translation cylinder 5 drives the demagnetizing coil 9 and the extension rod 10 to automatically return to the working position, waiting for the next part.
