Description

Technical Field

[0001] This utility model is a milling cutter that is easy to assemble and disassemble, belonging to the field of milling cutter technology. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. During operation, each cutting tooth sequentially and intermittently removes the excess material from the workpiece. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces.

[0003] Chinese patent CN220190569U proposes a permanent magnet synchronous motor that facilitates end cap installation. By fixing a positioning baffle to a designated position on the left side inside the cutter bar, the positioning baffle blocks and positions the two sets of locking rods, thereby preventing the milling cutter from shaking or slipping during use. However, during use, the fixed part of the milling cutter will be subjected to force and wear for a long time, which will cause the milling cutter to shake, resulting in a reduction in the life of the milling cutter and a deterioration in the machining effect. There is an urgent need for a milling cutter that is easy to disassemble and assemble to solve the above problems. Utility Model Content

The terminal block 9 is installed on the circumferential surface of the locking housing 3. The brush 8 is installed on the circumferential surface of the terminal block 9. The wire 7 is installed inside the milling cutter housing 1. The milling cutter fixing mechanism 2 includes a machining milling cutter 21.

This design solves the problem that when the fixed part of the original milling cutter is subjected to force and wear for a long time during use, the milling cutter will wobble, resulting in a reduction in the life of the milling cutter and a deterioration in the machining effect.

[0015] As the first embodiment of this utility model: two fixing grooves are formed on the circumferential surface of the milling cutter housing 1, and the outer side of the limiting block 24 is located inside the corresponding fixing groove. The two fixing grooves are 180° apart with the milling cutter housing 1 as the axis. A limiting groove is formed inside the fixing housing 23. Limiting plates 241 are installed on both sides of each limiting block 24. Each limiting plate 241 is located inside the corresponding limiting groove. Two limiting rods 25 pass through the corresponding limiting blocks 24. Four limiting guide rails are formed inside the milling cutter housing 1. The circumferential surface of the limiting post 22 is... Four limit bars are installed, each inside the limit guide rail. A permanent magnet is installed at the upper end of the limit post 22. The electromagnetic coil 5 is located at the upper end of the limit post 22 and is connected to the wire 7. Two conductive rings 6 are connected to the wire 7 respectively.

When the limiting block 24 reaches the fixed groove, the return spring 26 will push the limiting block 24 into the fixed groove. At this time, the milling cutter 21 and the limiting post 22 will be fixed inside the milling cutter housing 1. Then, the terminal 9 is energized, and the electromagnetic coil 5 is energized through the brush 8, the wire 7 and the conductive ring 6.
