[0024] like Figure 1-2 As shown, the worm processing cyclone milling cutter includes a cutter body 1 and a fixed disc 2. The fixed disc 2 is arranged at one end of the cutter body 1. The cutter body 1 is made of cemented carbide material to ensure that the cutter can withstand greater cutting force and wear during the worm processing process, and an adjustment component 3 is arranged between the cutter body 1 and the fixed disc 2. The adjustment group is used to adjust the cutting angle of the tool.

[0025] Among them, a processing hole 4 for the workpiece to pass through is opened in the middle of the cutter disc body 1 and the fixed disc 2, and a step 5 protruding axially outward is provided on the opposite surface of the cutter disc body 1 and the fixed disc 2. The step 5 has a number of positioning grooves 6 along the central axis, and the positioning grooves 6 are all connected to the processing hole 4. The positioning grooves 6 are trapezoidal and are arranged in a ring along the central axis of the tool 8 body.

[0026] like Figure 3-4 -5-6, the adjustment assembly 3 includes a swivel 7, a tool 8 and a pull rod 9. A slide groove 10 is provided between the step 5 and the cutter disc body 1. The swivel 7 is slidably arranged between the slide groove 10. The inner ring of the swivel 7 is provided with a groove 12. One end of the tool 8 is connected through the positioning shaft in the groove 12. The positioning groove 6 and the fixed disk 2 are respectively fixed with mutually socketed positioning grooves 11. The tool 8 is arranged inside the positioning groove 6. The middle part of the tool 8 is sleeved on the outside of the positioning groove 11. One end of the tool 8 is rotatably connected to the swivel 7. The pull rod 9 is fixed to the side of the swivel 7 close to the fixed disk 2, and the pull rod 9 passes through the fixed disk 2.

[0027] Among them, a positioning hole 13 is opened through the main body of the tool 8 and the fixed disk 2, and the positioning hole 13 is arranged in a ring along the central axis of the tool disk main body 1. The tool 8 and the positioning groove 6 and the fixed disk 2 are respectively provided with a gasket 14, and the gasket 14 is respectively bonded to the positioning groove 6 and the fixed disk 2. The tool disk main body 1 and the fixed disk 2 are connected by a number of fixing bolts, and the fixing bolts are arranged in a ring along the central axis of the tool disk main body 1.

[0028] The rotation of the swivel 7 in the over-adjustment component 3 drives one end of the tool 8 to rotate, so that the tool 8 rotates along the outside of the positioning groove 6, thereby realizing the adjustment of the angle of the tool 8. The angle of the tool 8 includes the front angle, the back angle, and the blade inclination angle to improve the cutting performance and life of the tool 8. For worm processing, larger front angles and back angles are generally used to reduce the cutting force and improve the cutting efficiency. The swivel 7 is locked by the fixing bolt, and the appropriate cutting depth is selected to avoid damage to the tool 8 and degradation of the processed surface quality due to excessive cutting depth, or reduced processing efficiency due to too small cutting depth, so as to reduce the cutting force and improve the cutting efficiency, thereby improving the cutting performance and life of the tool 8.

[0029] When the angle of the tool 8 needs to be adjusted, the fixing bolt that locks the swivel 7 is loosened, and the pull rod 9 is pulled. The pull rod 9 drives the swivel 7 to rotate in the slide groove 10, and the swivel 7 drives one end of the tool 8 to rotate and rotates around the outer periphery of the positioning groove 6. Due to the principle of lever, the other end of the tool 8 rotates accordingly, thereby realizing the adjustment of the angle of the tool 8. When it is adjusted to the required angle, the swivel 7 is locked by adjusting the fixing bolt to prevent the tool 8 from shaking during the processing.

[0030] Among them, according to the processing requirements of the worm and the power of the machine tool, the appropriate number of cutting edges of the tool 8 is selected. The more cutting edges the tool 8 has, the higher the cutting efficiency is, but the manufacturing difficulty of the tool 8 is also greater. Therefore, six sets of tools 8 are used for cutting operations.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents. In short, if those skilled in the art are inspired by the present invention and, without departing from the purpose of the present invention, design structures and embodiments similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
