Milling cutter carries out cutting to workpiece through rotary motion, can effectively remove the excess material on the surface of workpiece, and is processed into the shape and size required. Iron core processing usually requires high precision and surface quality, and milling cutter can ensure the precision and stability in the processing process while ensuring high efficiency. In the processing of iron core, the high-efficiency cutting performance of milling cutter can significantly shorten the processing time and improve the production efficiency. Especially in the processing of iron core with high hardness or complex shape, milling cutter can provide high-precision cutting to ensure smooth surface and accurate size. Milling cutter can realize various machining processes, such as face milling and slot milling, to meet the machining requirements of iron core with different shapes and sizes. In addition, milling cutter can effectively control the machining precision, avoid the errors or rough surface caused by traditional cutting methods, ensure that the size and shape of each iron core meet the design standards, and improve the product quality and performance. The application of milling cutter not only improves the machining efficiency, but also improves the machining quality of iron core, which meets the strict requirements of modern manufacturing industry for precision machining.

The blade is usually fixed on the cutter body by screws, and the other side of the blade relies on the embedded part of the cutter body for limiting and supporting. This wear will cause slight changes in the position of the blade, affecting the stability and precision of the cutting process, increasing the roughness of the machined surface, and exceeding the technical requirements of the machining precision. In addition, wear will also affect the fixation between the blade and the cutter body, and further cause vibration during cutting. Vibration not only affects the machining quality, but also accelerates the wear of the cutting tool, further shortening the service life of the cutting tool.

[0004] Therefore, we propose an iron core cutting tool. UTILITY MODEL CONTENTS

[0025] The inner wall of positioning rod 35 is provided with reinforcing mechanism 4, reinforcing mechanism 4 includes spring one 41, one end of spring one 41 is fixedly connected on the inner wall of positioning rod 35, the other end of spring one 41 is fixedly connected with reinforced connecting block 42, top connecting strip 43 is slidably connected on the inner wall of positioning rod 35, the outer wall of top connecting strip 43 is fixedly connected with one end of spring two 44, the other end of spring two 44 is fixedly connected with bottom connecting strip 45, the outer wall of reinforced connecting block 42 is slidably connected with the inner wall of positioning rod 35, the bottom of reinforced connecting block 42 is provided with inclined plane, reinforced connecting block 42 is provided with several, reinforced connecting block 42 is symmetrically arranged, the outer wall of bottom connecting strip 45 is slidably connected with the inner wall of positioning rod 35, the side of top connecting strip 43 close to reinforced connecting block 42 is arc-shaped.

[0026] The utility model discloses a kind of iron core cutting tools, the blade 2 needing to be positioned is placed on tool body 1 when using, at this time threaded rod 34, positioning rod 35 are inserted simultaneously through blade 2, then screwdriver is rotated bolt head 36, so that bolt head 36 drives threaded rod 34 to rotate, so that threaded rod 34 is screwed with internal thread groove 32, with internal thread groove 32 and threaded rod 34 are screwed with each other, positioning rod 35 and positioning groove 38 are inserted at this time, until bolt head 36 drives fixed sheet 33 to be closely in contact with the surface of blade 2, at this time installation is completed.

[0027] Positioning rod 35 can significantly enhance the stability between blade 2 and tool body 1 through the insertion effect with positioning groove 38. This principle is based on geometric constraints and mechanical positioning principle. Specifically, the precise insertion between positioning rod 35 and positioning groove 38 forms a geometric constraint, which limits the displacement or loosening of blade 2 during cutting due to external force or vibration, thereby ensuring that blade 2 always maintains a stable position. In addition, through insertion, positioning rod 35 helps to evenly distribute the force received by blade 2 during processing to the entire contact surface, avoiding excessive local stress and reducing friction and vibration between blade 2 and tool body 1. This uniform distribution of force not only improves the fixation and shock resistance between blade 2 and tool body 1, but also effectively reduces the relative displacement caused by vibration or friction, improving the stability of the cutting process. Positioning rod 35 provides additional fixing force through insertion with positioning groove 38. This fixing force ensures high precision of the insertion position through precision machining, allowing blade 2 to be precisely positioned on tool body 1, thereby ensuring that blade 2 is always in optimal working condition, maintaining the stability and precision of cutting. The insertion effect of positioning rod 35 and positioning groove 38 is equivalent to providing a locking mechanism for blade 2, effectively preventing blade 2 from loosening or position deviation during use, reducing processing errors or quality problems caused by inaccurate blade 2 position. Therefore, the insertion effect of positioning rod 35 and positioning groove 38 not only ensures the precise positioning between blade 2 and tool body 1, but also effectively enhances the stability of blade 2, preventing blade 2 position deviation caused by external factors during cutting, ensuring the precision and quality of the processing process.

[0028] When positioning rod 35 moves to the bottom of positioning groove 38, the bottom of positioning groove 38 is in contact with bottom connecting strip 45, causing bottom connecting strip 45 to be pressed against top connecting strip 43 through spring 44, and the arc-shaped portion at the top of top connecting strip 43 is in contact with the inclined surface of reinforced connecting block 42, causing reinforced connecting block 42 to move in the direction of compression spring 41, and causing reinforced connecting block 42 to be more closely in contact with the inner wall of positioning groove 38.

[0029] When the reinforced connecting block 42 is in close contact with the inner wall of the positioning groove 38, a strong locking mechanism is formed, which ensures the stable fixation of the blade 2 on the tool body 1 and reduces the loosening or position deviation of the blade 2 caused by external factors such as vibration and friction. Through this locking effect, the blade 2 maintains a more stable position during cutting, thereby improving the stability of cutting and machining precision. During cutting, vibration often causes the blade 2 to produce slight displacement or oscillation, which not only affects the quality of the machined surface, but also can cause cutting instability, further exacerbating tool wear. The close contact between the reinforced connecting block 42 and the positioning groove 38 effectively enhances the fixing force between the blade 2 and the tool body 1, so that the blade 2 is not easily disturbed by vibration, reducing the amplitude of vibration, thereby reducing the negative effects caused by vibration. This directly improves the stability of the cutting process, ensuring that the blade 2 always maintains an accurate position, thereby improving the working effect of the tool and the machining quality. Through this structure, the fixation between the blade 2 and the tool body 1 is effectively guaranteed, ensuring high-precision machining results and reducing machining errors caused by loosening or position deviation of the blade 2.
