Technical Field
[0001] This utility model relates to the field of milling cutters, specifically a multi-functional high-hardness tungsten steel milling cutter. Background Technology
[0002] In the field of machining, end mills are commonly used cutting tools. Among them, high-hardness tungsten carbide end mills are widely used in the machining of various metal materials due to their excellent hardness and wear resistance. However, traditional tungsten carbide end mills have relatively limited functionality, serving only as cutting tools and lacking versatility and convenience. In actual work, it is often necessary to disassemble or install end mills and tighten various sizes of threaded structures. These operations usually require the preparation of multiple tools, which not only increases the cost of carrying and storing tools but also reduces work efficiency.
[0003] Furthermore, when a milling cutter needs to be removed due to wear or damage, the lack of suitable tools can lead to difficulties in the disassembly process, or even damage to the threaded structure or the milling cutter itself. Therefore, there is an urgent need in the market for a multi-functional high-hardness tungsten carbide milling cutter that can be used as both a cutting tool and a wrench, and is compatible with various threaded structure sizes. Utility Model Content
[0004] The purpose of this invention is to provide a multifunctional high-hardness tungsten carbide end mill to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional high-hardness tungsten steel end mill, comprising a high-hardness tungsten steel end mill body, wherein an insert wrench is integrally formed on the top of the high-hardness tungsten steel end mill body, and a sleeve wrench is provided on the top surface of the insert wrench; both sides of the top surface of the high-hardness tungsten steel end mill body are rotatably connected to extension lever arms, which are used in conjunction with the insert wrench and the sleeve wrench.
[0006] Preferably, the insert wrench includes a hexagonal boss, which has a hexagonal plate-like structure and is located between two sets of extending lever arms.
[0007] Preferably, the socket-type wrench includes multiple layers of grooves, which are stepped.
[0008] Preferably, the multi-layered buckle groove includes hexagonal groove one, hexagonal groove two, and hexagonal groove three, wherein hexagonal groove one,
[0009] Hexagonal slot 2 and hexagonal slot 3 are arranged sequentially from bottom to top, and the slot opening size of hexagonal slot 1, hexagonal slot 2 and hexagonal slot 3 increases progressively.
[0010] Preferably, the top surface of the high-hardness tungsten carbide end mill body is provided with two side grooves, which are symmetrically distributed about the center of the top surface of the high-hardness tungsten carbide end mill body. The side grooves are used to accommodate the extension lever arm.
[0011] Preferably, the extending lever arm includes a limiting shaft, a through hole, and a lever. The limiting shaft is fixed between two parallel sidewalls of the side groove. The limiting shaft passes through the through hole, which is opened on the surface of the lever. The lever is square and its thickness is less than the lateral depth of the side groove.
[0012] Preferably, the surface of the paddle has an opening, and the end of the paddle away from the limiting shaft has a picking groove.
[0013] Preferably, rubber strips are fixed on both parallel sidewalls of the side groove. After the paddle is vertically stored inside the side groove, the paddle is limited by the slot and the side groove.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This utility model proposes a multi-functional high-hardness tungsten carbide end mill that integrates the functions of an insert wrench and a socket wrench into the end mill body. This allows the end mill to be used as a cutting tool while also functioning as a wrench, greatly facilitating tool use and portability, and reducing tool costs. The hexagonal boss design of the insert wrench allows it to be inserted into and drive the rotation of the hexagonal slotted threaded structure. The multi-layered groove design of the socket wrench accommodates three different sizes of hexagonal screw end plates, enhancing the wrench's applicability and flexibility. By adding a rotatable extension lever arm to the end mill body, when the end mill is used as a wrench, the user can simultaneously move two levers to increase the rotational torque using the lever principle, significantly reducing the force required to tighten the threaded structure and improving work efficiency.

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] Please see Figures 1-6 This utility model provides a technical solution: a multifunctional high-hardness tungsten carbide end mill, including a high-hardness tungsten carbide end mill body 1. The top of the high-hardness tungsten carbide end mill body 1 is integrally formed with an insert-type wrench. The insert-type wrench includes a hexagonal boss 2, which has a hexagonal plate-like structure and is located between two sets of extended lever arms. The reason for setting the hexagonal boss 2 on the top of the high-hardness tungsten carbide end mill body 1 is that when the high-hardness tungsten carbide end mill body 1 is disassembled and idle or damaged, the hexagonal boss 2 can be inserted into the screw connection structure set in the hexagonal slot. Rotating the high-hardness tungsten carbide end mill body 1 drives the screw connection structure to rotate through the hexagonal boss 2. At this time, the high-hardness tungsten carbide end mill body 1 can be used as a wrench.
[0025] The top surface of the insert wrench is equipped with a socket wrench, which includes multiple layers of grooves in a stepped shape. The grooves include hexagonal groove 1 3, hexagonal groove 2 4, and hexagonal groove 3 5, which are arranged sequentially from bottom to top, and the groove size of hexagonal groove 1 3, hexagonal groove 2 4, and hexagonal groove 3 5 increases progressively. After adding hexagonal groove 1 3, hexagonal groove 2 4, and hexagonal groove 3 5 to the top surface of the hexagonal boss 2, while satisfying the normal use of the hexagonal boss 2, hexagonal groove 1 3, hexagonal groove 2 4, and hexagonal groove 3 5 are respectively adapted to three standard-sized hexagonal screw end plates for tightening the screw end plates.
[0026] The high-hardness tungsten carbide end mill body 1 has two rotatably connected extension arms on both sides of its top surface, which are used in conjunction with insert wrenches and socket wrenches. The top surface of the high-hardness tungsten carbide end mill body 1 has two side grooves 6, which are symmetrically distributed about the center of the top surface of the high-hardness tungsten carbide end mill body 1. The side grooves 6 are used to accommodate the extension arms. The extension arms include a limiting shaft 7, a through hole 8, and a lever 9. The limiting shaft 7 is fixed between two parallel side walls of the side groove 6 and passes through the through hole 8. The through hole 8 is opened on the surface of the lever 9. The lever 9 is square and its thickness is less than the lateral depth of the side groove 6. The surface of the lever 9 has an opening 10, and the end of the lever 9 away from the limiting shaft 7 has a slot 11. Rubber strips 12 are fixed on both parallel side walls of the side groove 6. After the lever 9 is vertically stored inside the side groove 6, the lever 9 is limited by the slot 11 and the side groove 6.
[0027] The reason for adding the lever 9 is to make it easier to use the wrench structure when using the high-hardness tungsten carbide end mill body 1. After the lever 9 is vertically retracted into the side groove 6, the lever 9 is blocked by the rubber strip 12 to prevent the lever 9 from swinging in the side groove 6. At this time, the top of the high-hardness tungsten carbide end mill body 1 can be inserted into the tool body clamp for normal installation. When the high-hardness tungsten carbide end mill body 1 is disassembled, the finger is placed in the picking groove 11 and the lever 9 is rotated around the limiting shaft 7. During this process, the lever 9 passes over the rubber strip 12. When both levers 9 are adjusted to extend from the side groove 6, the two levers 9 are moved at the same time to drive the high-hardness tungsten carbide end mill body 1 to rotate, saving the force required to rotate the high-hardness tungsten carbide end mill body 1 to drive the wrench to tighten the screw structure.
[0028] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
