Description

Technical Field

[0001] This utility model relates to the field of milling cutter technology, and in particular to a composite milling cutter. Background Technology

[0002] In the field of machining, end mills are key tools for achieving high-precision material cutting, and their performance directly affects machining efficiency, product quality, and production costs. Traditional end mills have relatively simple functions, and when faced with complex and diverse machining needs, they often require frequent tool changes. This not only increases the complexity of the operation process but also easily introduces errors due to multiple clamping and tool setting, making it difficult to guarantee machining accuracy and reducing production efficiency.

[0003] Traditional composite cutting tools exhibit significant lifespan variations across different cutting positions, leading to premature end of the overall tool life and frequent tool replacements. This drastically increases tooling costs. Uneven tool wear also makes them unsuitable for machining various materials, further increasing production costs and management complexity.

[0004] With the rise of high-end industries such as aerospace and automobile manufacturing, the application of difficult-to-machine materials such as stainless steel, titanium alloys, and aluminum alloys, as well as carbon fiber composite materials and composite laminated materials, is becoming increasingly widespread. These materials have characteristics such as high strength, high toughness, and low thermal conductivity, posing greater challenges to the wear resistance, heat resistance, and fatigue resistance of end mills. Traditional end mills are prone to problems such as accelerated wear, chipping, excessively high cutting temperatures, and poor chip removal, affecting machining quality and tool life. To address the above issues, a composite end mill is proposed. Utility Model Content

The rotating gear two has multiple grooves inside, a connecting rotating rod slidably connected inside the rotating gear two, a connecting sliding rod fixedly connected to the outside of the connecting rotating rod, multiple supporting sliding rods fixedly connected to the outside of the rotating gear two, and a connecting sliding block fixedly connected to the outside of the connecting sliding rod. As a further description of the above technical solution: The multi-layer mechanism includes an anti-wear mechanism, the anti-wear mechanism is externally fixedly connected to a waterproof layer, and the waterproof layer is externally fixedly connected to a connecting support layer. As a further description of the above technical solution: The connecting sliding block is externally slidably connected to the outside of the protective housing, and the connecting sliding rod is externally slidably connected to the outside of the protective housing; As a further description of the above technical solution: The supporting sliding rod is rotatably connected to the outside of the protective housing, and the rotating gear two is rotatably connected to the outside of the protective housing.

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.

[0012] Reference Figures 1 to 3 The present invention provides an embodiment of a composite milling cutter, comprising a protective shell 1, a connecting mechanism 2 fixedly connected to the outside of the protective shell 1, and a multi-layer mechanism 3 fixedly connected to the inside of the protective shell 1. The connecting mechanism 2 includes a driving component 21 for driving, which is the source of power transmission for the entire composite milling cutter. Its core component is a rotating motor 211. A rotating gear 22 is fixedly connected to the outside of the driving component 21, and the rotating gear 22 plays the role of power transmission in the connecting mechanism 2. The outer casing 1 is rotatably connected to a rotating gear 23. When the rotating gear 1 drives the rotating gear 23 to rotate, the external teeth of the rotating gear 1 and the external teeth of the rotating gear 23 mesh with each other. The rotating gear 23 has multiple grooves inside. The rotating gear 23 is slidably connected to a connecting rotating rod 24 inside. The connecting rotating rod 24 is an important connecting part that connects the rotating gear 23 to other components and plays the role of power transmission and motion conversion. The connecting rotating rod 24 is fixedly connected to a connecting sliding rod 26 outside. The rotating gear 23 is externally fixedly connected to multiple supporting sliding rods 25. The supporting sliding rods 25 mainly play the role of supporting and assisting movement in the connecting mechanism 2. The connecting sliding rod 26 is externally fixedly connected to a connecting sliding block 27. The connecting sliding rod 26 and the connecting sliding block 27 cooperate with each other to convert the power transmitted from the connecting rotating rod 24 into linear sliding motion. The connecting sliding block 27 is externally slidably connected to the outside of the protective shell 1, the connecting sliding rod 26 is externally slidably connected to the outside of the protective shell 1, and the supporting sliding rod 25 is externally rotatably connected to the outside of the protective shell 1. The external rotating gear 23 is rotatably connected to the outside of the protective housing 1, the external rotating rod 24 is rotatably connected to the outside of the protective housing 1, the external rotating gear 22 is rotatably connected to the outside of the protective housing 1, the drive assembly 21 includes a rotating motor 211, the drive end of the rotating motor 211 is fixedly connected to a rotating connecting rod 212, when the rotating connecting rod 212 starts to rotate under the drive of the rotating motor 211, the rotating gear 22 fixedly connected to it rotates synchronously, and the external rotating motor 211 is fixedly connected to the outside of the protective housing 1.

[0013] Reference Figure 1 , Figure 4 The multi-layer mechanism 3 includes an anti-wear mechanism 31. As the outermost layer of the multi-layer mechanism 3, the anti-wear mechanism 31 is in direct contact with the working environment of the milling cutter. Its main function is to protect the internal structure of the milling cutter. A waterproof layer 32 is fixedly connected to the outside of the anti-wear mechanism 31. The waterproof layer 32 is set outside the anti-wear mechanism 31 and is mainly used to prevent cutting fluid, coolant and other liquids from seeping into the inside of the milling cutter, protecting the internal structure of the milling cutter and the connecting mechanism 2 from liquid corrosion. A connecting support layer 33 is fixedly connected to the outside of the waterproof layer 32. The connecting support layer 33 plays a dual role of connection and support, tightly connecting the anti-wear mechanism 31, the waterproof layer 32 and the supporting and solid inner core 34 together, so that the multi-layer mechanism 3 forms a complete whole and ensures the coordinated work between the layers. The rotating connecting rod 212 is externally rotatably connected to the outside of the protective shell 1. The rotating connecting rod 212 is externally fixedly connected to the outside of the rotating gear 22. The supporting support layer 33 is externally fixedly connected to the supporting core 34. The supporting core 34 is the core support structure of the multi-layer mechanism 3, providing strong structural strength for the entire milling cutter. The anti-wear mechanism 31 is externally fixedly connected to the inside of the protective shell 1.

[0014] Working principle: When it is necessary to fix the position of the protective shell 1, the operation of the rotating motor 211 drives the rotating connecting rod 212 and the rotating gear 1 22 to rotate, thereby driving the rotating gear 23 to rotate, which in turn drives the rotating connecting rod 24 and the connecting sliding rod 26 to rotate. At the same time, the supporting sliding rod 25 provides support for the rotation of the connecting sliding rod 26, thereby achieving the outward sliding of the connecting sliding block 27, which can fix the protective shell 1 on machinery of different sizes.

[0015] The outermost wear-resistant mechanism 31 faces the working environment directly and is made of wear-resistant material to protect the internal structure. The waterproof layer 32 is tightly attached to the wear-resistant mechanism 31 to prevent internal components from rusting. The connecting support layer 33 connects the wear-resistant mechanism 31, the waterproof layer 32 and the supporting and sturdy inner core 34, so that the multi-layer mechanism 3 forms a whole. At the same time, it disperses external forces, enhances the stability of the milling cutter structure, and ensures the shape and machining accuracy of the milling cutter. The layers cooperate with each other to improve the performance and service life of the milling cutter.

[0016] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
