Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-frequency transformer manufacturing, and in particular to an automatic grinding inductance testing mechanism. Background Technology
[0002] A high-frequency transformer is an electrical device used in high-frequency circuits and is widely used in switching power supplies, communication equipment, and power electronics. Compared with traditional low-frequency transformers, high-frequency transformers operate at frequencies between tens of kilohertz and hundreds of megahertz. Their core materials, winding designs, and magnetic field characteristics are significantly different. The core materials of high-frequency transformers are iron powder cores or ferrite materials to reduce high-frequency losses and hysteresis losses, ensuring the efficient operation of the transformer. Special attention needs to be paid to factors such as inter-turn capacitance and leakage inductance in the winding design to reduce the loss of high-frequency signals.
[0003] In switching power supplies, high-frequency transformers play a role in voltage boosting, isolation, and current regulation. They can efficiently convert DC power into high-frequency AC power, and then convert it back to the required DC power through rectification and filtering. Their advantages are small size, light weight, and high efficiency, making them suitable for miniaturized and high-efficiency electronic devices. The working principle of high-frequency transformers mainly relies on the principle of electromagnetic induction, and energy is transferred by changing the ratio of voltage and current. The design needs to take into account high-frequency characteristics, magnetic saturation, and temperature rise, so there are high requirements for material selection, structural design, and manufacturing process.
[0004] In the traditional transformer manufacturing process, the production of magnetic cores relies on the back-and-forth extension and retraction of cylinders for grinding. This process is not only inefficient and slow, but also generates a lot of noise, which interferes with the production environment. Furthermore, it lacks the function of real-time inductance testing, which can easily lead to instability and quality fluctuations in production. Therefore, an automatic grinding inductance testing mechanism is proposed to solve the above problems. Utility Model Content

The operating table 1 supports and facilitates operation of the workpiece 3. The placement table 2 supports the workpiece 3. The fixing frame 4 supports the torque motor 5, which drives the connecting rod 17 to deflect. The connecting rod 17 pushes and pulls the fixing block 7. The slide rail 6 restricts the movement direction of the fixing block 7. The fixing block 7 fixes the cylinder 8, which pushes the top block 9 to move. The top block 9 contacts the workpiece 3 and moves it. A cylinder 10 pushes the top block 11 to move, which contacts the workpiece 3 to keep it stable. 2 is used to drive the two clamping blocks 14 to move simultaneously. The slide rail 2 13 is used to limit the movement direction of the clamping blocks 14. The clamping blocks 14 are used to clamp the workpiece 3 and keep the workpiece 3 stable. A test assembly is installed on the top of the operating table 1. The test assembly includes a cylinder 4 15. The bottom of the cylinder 4 15 is fixedly connected to the top of the operating table 1. A test probe 16 is fixedly connected to the output end of the cylinder 4 15. The cylinder 4 15 is used to drive the test probe 16 to move.

Then, control cylinder 3 12 to drive clamping block 14 to move on slide rail 2 13, so that clamping block 14 clamps workpiece 3. Then, control cylinder 2 10 to push top block 2 11 to firmly hold workpiece 3. Then, control cylinder 1 8 to drive top block 1 9 to hold the other side of workpiece 3. Then, control cylinder 4 15 to drive test probe 16 to move, so that test probe 16 contacts the pin of workpiece 3. Finally, control the torque motor 5 to rotate, and under the limit of slide rail 1 6, the connecting rod 17 pushes and pulls the fixing block 7, driving cylinder 1 8 to move back and forth, thereby grinding workpiece 3. When the data detected by test probe 16 indicates that the grinding has reached a suitable value, torque motor 5 stops immediately and controls each cylinder to disengage from workpiece 3. Workpiece 3 is removed and the next workpiece 3 is placed on it, and the above operation can continue. The operation is convenient and labor-saving, and the grinding accuracy can be precisely controlled.
