Description

Technical Field

[0001] This utility model relates to the field of milling cutter design technology, specifically to an anti-vibration carbide milling cutter. 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. When fixing a milling cutter, care should be taken to prevent vibration. Fixing it internally in a clamping assembly can better adapt to milling operations. Existing milling cutters can be modified.

[0003] Therefore, it is essential to design a carbide end mill that is both practical and structurally stable to prevent vibration. Utility Model Content

[0004] The purpose of this invention is to provide a carbide end mill with anti-vibration to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibration-resistant carbide end mill, comprising a base, a housing on one side of the base, a toothed ring rotatably connected inside the housing, a plurality of rods on one side of the toothed ring, plates on both sides of the rods, a plurality of rods fixedly connected inside the housing, the plates rotatably connected to the surfaces of the rods, a cutter body disposed between the plates, a fixed seat fixedly connected to the outside of the housing, a screw threadedly connected inside the fixed seat, a gear fixedly connected to one end of the screw, and a groove provided on the surface of the housing, the gear meshing with the toothed ring.

[0006] According to the above technical solution, the thickness of the gear is less than that of the gear ring.

[0007] According to the above technical solution, the thickness of the gear is less than that of the gear ring.

[0008] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0009] (1) By setting a screw assembly, the cutter body is inserted between the plates. The screw is rotated and connected to the screw thread inside the fixed seat. At this time, it moves downward and the gear is also driven to rotate. One side of the gear meshes with the gear ring, and its thickness is less than that of the gear ring, so that it will not disengage from the gear ring and conflict with the hole groove. As the gear ring rotates, the gear ring drives the rod one to make a displacement of the whole circumferential trajectory. The rod one pushes against the plate and rotates around the rod two, thereby clamping the cutter body between the plates. Since the thread has self-locking property, the gear and the gear ring will not shake or rotate without manual force to rotate the screw. The overall structure is stable. The external rotating screw can fix it. The operation is convenient. The protective part is used to protect the gear assembly. The double fixation of two layers of plates greatly reduces the vibration. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4This utility model provides a technical solution: a vibration-resistant carbide end mill, including a base 2, a housing 3 on one side of the base 2, a toothed ring 9 rotatably connected inside the housing 3, several rods 10 on one side of the toothed ring 9, plates 12 on both sides of the rods 10, several rods 21 fixedly connected inside the housing 3, plates 12 rotatably connected to the surfaces of the rods 21, a cutter body 1 between the plates 12, a fixed seat 5 fixedly connected to the outside of the housing 3, a screw 6 threadedly connected inside the fixed seat 5, a gear 7 fixedly connected to one end of the screw 6, a groove 8 on the surface of the housing 3, the gear 7 meshing with the toothed ring 9, the thickness of the gear 7 being less than that of the toothed ring 9, and a protective member 4 on one side of the housing 3.

[0017] Specifically, the cutter body 1 is inserted between the plates 12, and the screw 6 is rotated. The screw 6 is threadedly connected to the fixed seat 5 and moves downward. At this time, the gear 7 is also driven to rotate. One side of the gear 7 meshes with the gear ring 9, and its thickness is less than that of the gear ring, so that it will not disengage from the gear ring 9 and will not conflict with the hole groove 8. As the gear ring 9 rotates, the gear ring 9 drives the rod 10 to make a circumferential displacement. The rod 10 pushes against the plate 12 and rotates around the rod 2 11, thereby clamping the cutter body 1 between the plates 12. Since the thread has self-locking properties, the gear and the gear ring 9 will not shake or rotate without manual force to rotate the screw 6. The overall structure is stable, and the external screw can be rotated to fix it. The operation is convenient. The protective part 4 is used to protect the gear assembly. It is double-fixed by two layers of plates 12, which greatly reduces vibration.

[0018] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
