[0049] The cutting edge 302 at one corner of the blade 301 close to the axis of the base disc 1 is provided with a machining position slot 202 at the position corresponding to the limiting groove 201, so that the cutting edge 302 is arranged in the base disc 1 and in contact with the shaft of the base disc 1 to realize cutting.

[0050] The positions corresponding to the other two corners of the blade 301 are provided with protection grooves 203, and the groove surface of the protection groove 203 is not in contact with the blade 301, which is used to protect the cutting edges 302 of the other two corners of the blade 301 and avoid scratching the groove surface of the limiting groove 201.

[0051] The groove surface of the limiting groove 201 away from the machining position slot 202 is close to the angle adjusting structure 4, and the upper part of the groove surface is provided with a clearance slope 204 facing the groove top of the limiting groove 201.

[0052] Further, the angle adjusting structure 4 is arranged between the machining tool 3 and the groove bottom of the tool groove 2, which is used to change the relative angle between the machining tool 3 and the base disc 1, so as to adjust the machining angle of the machining tool 3 and the shaft to be machined, and cut the thread grooves 603 of different specifications.

The threaded column 405 is connected with the base disc 1 through thread matching. When the threaded column 405 rotates, the support block 402 can be displaced relative to the base disc 1, and the support block 402 is displaced from the outside of the base disc 1 to the inside of the base disc 1 through the rotation of the threaded column 405.

[0056] The support block 402 is slidingly arranged in the sliding groove 401, the sliding groove 401 is arranged in the base disc 1, the sliding groove 401 is communicated with one side of the limiting groove 201, the support block 402 is slidingly arranged in the limiting groove 201, the lower end of the support block 402 is slidingly arranged on the groove bottom surface of the limiting groove 201, and the upper end of the support block 402 is in abutment with the bottom of the blade 301. Because the support block 402 is fixedly arranged at the end away from the threaded column 405, the inclined block 403 is arranged on the support block 402, and the inclined surface of the inclined block 403 faces the bottom of the blade 301.

[0057] And the angle supporting structure 5 is arranged between the machining tool 3 and the top of the tool groove 2, the angle adjusting structure 4 is arranged at the end of the machining tool 3 away from the machining position, and the angle supporting structure 5 is arranged at the end of the machining tool 3 close to the machining position. The machining tool 3 can swing around the position of the angle fixing structure 6 as a fulcrum.

[0058] Preferably, when the threaded column 405 is rotated, the support block 402 slides towards the blade 301 and the limiting groove 201, the inclined block 403 on the support block 402 guides one end of the blade 301 to the support block 402, and the other end of the blade 301 swings around the position of the angle fixing structure 6 as a fulcrum; when the support block 402 approaches the position of the angle fixing structure 6, the blade 301 starts to do lever movement under the pushing of the support block 402, so that the end of the blade 301 close to the machining position swings downward, and the angle between the blade 301 and the base disc 1 increases, so that the angle of the blade 301 is adjusted.

[0059] It is worth noting that the end of the blade 301 close to the sliding groove 401 is provided with a chamfer 305, when the support block 402 in the sliding groove 401 slides into the limiting groove 201, the inclined surface of the inclined block 403 on the support block 402 can be clamped into the inclined surface of the chamfer 305, so as to enter between the blade 301 and the groove bottom of the limiting groove 201, and drive the blade 301 to swing.

[0060] In addition, the avoiding inclined surface 204 is arranged on the end groove surface of the limiting groove 201 away from the machining position slot 202, the avoiding inclined surface 204 is located on the upper part of the groove surface, and the avoiding inclined surface 204 faces the groove top of the limiting groove 201.

[0061] Preferably, when the angle adjustment of the blade 301 is not performed, the blade 301 is placed in the clamping groove 201 and is separated from the angle support structure 5; when the angle adjustment is performed by rotating the threaded column 405, the supporting block 402 pushes the blade 301 from the bottom of the blade 301, and the blade 301 is limited by the shape of the clamping groove 201 and cannot rotate, but moves upward in the clamping groove 201 until the chamfer 305 of the blade 301 slides to the avoiding inclined surface 204 on the upper part of the clamping groove 201, at this time, the blade 301 also abuts against the angle support structure 5, so that the chamfer 305 of the blade 301 starts to get rid of the limitation of the clamping groove 201 and slides on the avoiding inclined surface 204, so that the blade 301 is no longer aligned with the clamping groove 201, and the blade 301 starts to swing to realize the angle adjustment; during the swinging of the blade 301, the blade 301 is moved upward in the previous process and has a certain spacing with the bottom of the clamping groove 201, so that a gap space for relative swinging without interference is generated between the blade 301 and the clamping groove 201, so that the angle swinging of the blade 301 is realized normally.

[0062] Further, the angle support structure 5 is used for providing a swinging fulcrum for the angle swinging of the machining tool 3 and maintaining the normal swinging thereof.

[0063] Please refer to Figure 4 and Figure 5 In the embodiment, the angle support structure 5 includes a rotating member, the rotating member is composed of a fixed end and a rotating end, the fixed end is arranged on the top of the tool groove 2, and the rotating end is connected to the top of the machining tool 3, so that the machining tool 3 swings relative to the tool groove 2.

[0064] The fixed end of the rotating member includes a ring-shaped pressing plate 501, a fixed screw 502 and an arc-shaped block 503.

[0065] The rotating end of the rotating member includes an arc-shaped groove plate 504.

[0066] Specifically, the ring-shaped pressing plate 501 is located on the surface of the base disc 1 and is screwed and locked with the base disc 1 through the fixed screw 502, a plurality of arc-shaped blocks 503 are fixedly connected on the ring-shaped pressing plate 501, and each tool groove 2 is matched and corresponded with one arc-shaped block 503.

[0067] The arc-shaped block 503 is located on the top of the clamping groove 201, the bottom of the arc-shaped block 503 is an arc-shaped protrusion, and the bottom of the arc-shaped block 503 is located in the clamping groove 201; the arc-shaped groove plate 504 is fixedly arranged on the top surface of the blade 301, the top of the arc-shaped groove plate 504 is an arc-shaped concave surface, and the arc-shaped concave surface is matched and rotationally connected with the arc-shaped protrusion of the arc-shaped block 503.

[0068] Preferably, please refer to Figure 8When the angle adjustment of the blade 301 is not performed, the blade 301 is located at the groove bottom of the limiting groove 201, and the arc-shaped groove plate 504 on the blade 301 is separated from the arc-shaped block 503; please refer to Figure 5 When the blade 301 is pushed by the bottom supporting block 402, the blade 301 moves upward, and the arc-shaped groove plate 504 moves upward and is matched with the arc-shaped block 503 in clamping. At this time, when the supporting block 402 continues to push the blade 301, the blade 301 is blocked by the arc-shaped block 503, and starts to swing through the lever action, thereby realizing the angle adjustment of the blade 301.

[0069] Further, the machining tool 3 is provided with an angle fixing structure 6 at the end away from the machining position, which is used to limit and fix the blade 301 after the blade 301 is separated from the limiting of the limiting groove 201 in the angle adjustment.

[0070] The angle fixing structure 6 comprises a sliding column 601, a sliding cavity 602, a threaded groove 603, and a nut 604.

[0071] Specifically, the sliding column 601 is fixedly connected to the side surface of one end of the chamfer 305 of the blade 301, the sliding column 601 is arranged in the sliding cavity 602, the sliding cavity 602 is arranged in the base disc 1, one end of the sliding cavity 602 is communicated with the limiting groove 201, and the other end penetrates the outer wall of the base disc 1. The end of the sliding column 601 away from the blade 301 is provided with the threaded groove 603, and the threaded groove 603 is threadedly matched with the nut 604. The end of the sliding column 601 provided with the threaded groove 603 penetrates out of the base disc 1.

[0072] Preferably, when the blade 301 moves upward in the limiting groove 201, the sliding column 601 vertically slides in the sliding cavity 602. When the blade 301 starts to swing, the sliding column 601 swings in the sliding cavity 602, and the swinging direction is the vertical direction. The sliding cavity 602 is used to limit the transverse displacement direction of the blade 301 on the sliding column 601, that is, perpendicular to the rotating direction of the rotating member, so as to avoid that the blade 301 is still limited by the sliding cavity 602 after the blade 301 moves upward and separates from the limiting of the limiting groove 201, and avoid that the blade 301 deviates from the machining position and affects the machining. When the angle adjustment of the blade 301 is completed, the nut 604 is tightened, so that the nut 604 abuts against the outer wall of the base disc 1, and the swung blade 301 is fixed.

[0073] It is worth noting that, because the machining tool 3 is used to machine the helical groove on the surface of the shaft member in the embodiment, the main force borne by the blade 301 in the machining process is in the direction that the blade 301 follows the rotating direction of the base disc 1 (because it is necessary to cut the helical groove along the axial direction of the shaft member), and the force acting on the axial direction of the base disc 1 is small. Therefore, the frictional resistance between the nut 604 and the base disc 1 can ensure that the blade 301 will not be loosened after the angle adjustment.

[0074] In addition, please refer to Figure 6 In the embodiment, the flexible gasket 7 is further arranged between the nut 604 and the outer wall of the base disc 1, the flexible gasket 7 is sleeved on the slide column 601, and the flexible gasket 7 is arranged as an elastic rubber pad.

[0075] It is preferred that the outer wall surface of the base disc 1 is a curved surface, the slide column 601 also swings at an angle relative to the base disc 1, the surface area of the base disc 1 abutting against the nut 604 is small, the frictional resistance is also small, and therefore the elastic rubber pad capable of elastically deforming is arranged between the two, the deformation of the rubber pad and the larger frictional resistance of the surface of the rubber pad can generate larger frictional resistance between the nut 604 and the base disc 1 when the nut 604 locks the blade 301, and the flexible gasket 7 can avoid the blade 301 from being loosened.
