TECHNICAL FIELD
[0001] The utility model belongs to the field of iron core processing, specifically relates to a tool fixture for iron core processing. BACKGROUND
[0002] Iron cores are widely used in the fields of electronics and communication as components of power transformers or inductors. The manufacturing process of iron core products includes powdering, molding, sintering, grinding, and packaging, a total of five processing procedures. In the grinding process of the iron core, the presence of impurities or burrs on the back surface of some products cannot guarantee the inductance value, parallelism, and appearance of the products. Therefore, a fixture is needed to fix the products during the grinding process.
[0003] Chinese Patent No. CN220074477U discloses a tool fixture for iron core processing, which solves the problem of inaccurate processing of the iron core due to the difficulty of positioning the iron core in the center between two clamping plates. The tool fixture includes a base, a lifting mechanism installed on the top of the base, and a clamping mechanism installed on the top of the lifting mechanism. The lifting mechanism includes a U-shaped bracket fixed to the top of the base, two side grooves symmetrically arranged inside the U-shaped bracket, two vertical columns fixedly installed inside the two side grooves, two sliding blocks movably installed on the outer sides of the two vertical columns, and two clamping plates slidably connected to the two sliding blocks. The tool fixture facilitates the upward movement of the lifting plate and the iron core placed on the top of the placing disc, so that the iron core can be positioned in the center between the two clamping plates, thereby facilitating accurate processing of the iron core.
[0004] In actual use, the existing technology drives the iron core to move up and down through the lifting plate, and then drives the screw to rotate through the rotation of the second rotary disc, which moves the movable rod two on both sides of the screw bushing, and moves the clamping plate on one side of the movable plate to clamp the iron core. However, since the clamping plate is arc-shaped, and the iron core is larger than the clamping plate, it will cause wear and shaking. When the iron core is smaller than the clamping plate, it will shake during processing. Therefore, a tool fixture for iron core processing is needed.
[0005] Therefore, the utility model is proposed. UTILITY MODEL CONTENTS
