Description

Technical Field

[0001] The utility model belongs to the technical field of milling cutters, and particularly relates to a multi-functional hole-expanding milling cutter. Background Technique

[0002] A milling cutter is a common cutting tool for machining the surface of a workpiece. According to different machining tasks, milling cutters can be divided into ordinary milling cutters and hole-expanding milling cutters. A hole-expanding milling cutter can machine an existing round hole into a larger round hole or a polygonal hole. It is a milling cutter, not a drill bit. The characteristic of a hole-expanding milling cutter is the inserted teeth composed of two or more cutting edges. The tooth pitch corresponds to the hole diameter. The inserted teeth can quickly and stably increase the diameter of the existing hole and can perform milling during the machining process. A hole-expanding milling cutter usually does not drill holes in metal workpieces but processes existing holes. Hole-expanding milling cutters are widely used in the aviation, automotive, and mold industries. However, in existing hole-expanding milling cutters, when installing the milling cutter, it is not stable enough, and the milling cutter cannot work better. Therefore, a multi-functional hole-expanding milling cutter is proposed.

[0003] For example, the Chinese patent with the publication number CN204135429U discloses a multi-functional hole-expanding milling cutter, which overcomes the problem of deviation in the coaxiality of stepped holes caused by inaccurate tool alignment during the multi-inner-diameter hole-expanding process in the prior art. The utility model includes a primary hole-expanding drill rod and a primary hole-expanding milling cutter. The primary hole-expanding milling cutters are annularly and evenly distributed at one end of the primary hole-expanding drill rod. A secondary hole-expanding milling cutter is sleeved outside the primary hole-expanding drill rod, and an adjusting device for fixing it on the primary hole-expanding drill rod is provided on the secondary hole-expanding milling cutter.

[0004] The above patent has the following problems:

[0005] Compared with the prior art, when the milling cutter is installed and fixed, it is not stable enough. After long-term use, the bolts may become stripped, resulting in the unstable operation of the milling cutter, thus affecting the normal operation of the milling cutter and its working efficiency. Moreover, in the prior art, the milling cutter is not provided with a protective sleeve and cannot be protected when not in use, which may cause the milling cutter to be corroded and affected by moisture, affecting the service life of the milling cutter and increasing the manufacturing cost of the milling cutter. In view of this, we propose a multi-functional hole-expanding milling cutter. Content of the Utility Model

[0006] The purpose of the utility model is to provide a multi-functional hole-expanding milling cutter for the above-mentioned existing technical problems, achieving the effects of stable installation and setting a protective sleeve.

[0007] In view of this, the utility model provides a multi-functional reaming milling cutter, including a tool shank, and further including: a cutter head is movably installed on one side of the tool shank, bolts are movably installed at both ends of the other side of the cutter head, gaskets are fixedly arranged between the bolts, a limiting groove is fixedly arranged inside the cutter head, a positioning screw is movably installed inside the limiting groove, a protective sleeve is movably installed on the surface of the cutter head, a waterproof layer is fixedly arranged inside the protective sleeve, an anti-corrosion layer is fixedly arranged inside the waterproof layer, and limiting blocks are fixedly installed inside the anti-corrosion layer.

Then, the protective sleeve can be used to protect the cutter head. Then, the waterproof layer can be used to protect the cutter head to prevent water pollution. Then, the anti-corrosion layer can be used to carry out anti-corrosion work on the cutter head. Combined with the waterproof layer, it can extend the service life of the cutter head. Then, the limiting blocks can be used to limit the cutter head inside the anti-corrosion layer to improve stability. With combined use, it can protect the cutter head, protect it when not in use, prevent the cutter head from being corroded and affected by moisture, not affect the service life of the cutter head, and reduce the manufacturing cost of the cutter head.

[0009] Preferably, first ventilation holes are fixedly arranged at both ends of the tool shank, and first dust-proof nets are fixedly arranged inside the first ventilation holes. An installation plate is fixedly installed on one side of the tool shank to ventilate the inside of the tool shank.
