Description

Technical Field

[0001] This utility model belongs to the field of cutting tool technology, and relates to a milling cutter, particularly a high-precision carbide milling cutter. Background Technology

[0002] Currently, most milling cutters are of a single, integrated structure, with multiple cutter bodies molded together on the cutter head. When several of these cutter bodies are damaged, the entire milling cutter structure needs to be replaced, resulting in high wear and significantly increased replacement costs. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a high-precision carbide end mill with a separate cutter body.

[0004] The objective of this utility model can be achieved through the following technical solution: A high-precision carbide end mill, including a cutter head, characterized in that multiple cutter grooves are formed along the circumferential direction at the upper edge of the cutter head, and a cutter body is installed in each of the cutter grooves. The cutter body is installed into the cutter groove of the cutter head by screws. The cutter body has a mounting surface and a clamping surface. The mounting surface has several raised limiting ribs. A clamping member is provided between the clamping surface and the cutter groove, and the clamping surface is pressed by the clamping member to limit the cutter body. Both sides of the clamping member have integrally formed limiting posts. The outer wall of the limiting post has an arc surface structure. The cutter head has a limiting groove for guiding the limiting ribs to extend into and a guide groove for guiding the limiting post at one end of the clamping member to extend into. The cutter body has an extension groove for the limiting post at the other end of the clamping member to extend into.

[0005] In the aforementioned high-precision carbide end mill, corresponding screw holes are provided on both the cutter body and the cutter groove.

[0006] In the aforementioned high-precision carbide end mill, the cutter head has a shaft hole in the middle.

[0007] Compared with existing technologies, this high-precision carbide end mill has the advantages of high-precision installation and high-precision machining. Attached Figure Description

[0008] Figure 1 This is a 3D view of a high-precision carbide end mill.

[0009] Figure 2 This is a structural diagram of a single cutter body mounted on the cutter head in this high-precision carbide end mill.

[0010] In the figure, 1 is the cutter head; 2 is the cutter body; 3 is the mounting surface; 4 is the clamping surface; 5 is the limiting rib; 6 is the clamping component; 7 is the limiting post; 8 is the limiting groove; 9 is the guide groove; 10 is the extension groove; 11 is the screw hole; and 12 is the shaft hole. Detailed Implementation

[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0012] like Figure 1-2 As shown, this high-precision carbide end mill includes a cutter head 1. Multiple slots are formed along the circumference of the upper edge of the cutter head 1, and a cutter body 2 is installed in each slot. The cutter body 2 is installed into the slot of the cutter head 1 by screws. The cutter body 2 has a mounting surface 3 and a clamping surface 4. The mounting surface 3 has several raised limiting ribs 5. A clamping element 6 is provided between the clamping surface 4 and the slot. The clamping surface 4 is pressed together by the clamping element 6 to limit the cutter body 2, thereby positioning the cutter body 2 and improving the installation accuracy of the cutter body 2, thus improving the subsequent machining accuracy of the cutter body 2. The clamping component 6 has integrally formed limiting posts 7 on both sides. The outer wall of the limiting post 7 is an arc surface structure. The cutter head 1 has a limiting groove 8 for the limiting rib 5 to extend into and a guide groove 9 for the limiting post 7 at one end of the clamping component 6 to extend into. The cutter body 2 has an extension groove 10 for the limiting post 7 at the other end of the clamping component 6 to extend into. The clamping component 6 of the corresponding thickness is selected according to different milling cutters and milling cutter body 2. The limiting structure limits the milling cutter body 2 to prevent the cutter body 2 from being misaligned when it is installed alone.

[0013] Preferably, the cutter body 2 and the cutter groove are provided with corresponding screw holes 11.

[0014] Preferably, the cutter head 1 has a shaft hole 12 in the middle.

[0015] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0016] Although this document frequently uses terms such as cutter head 1, cutter body 2, mounting surface 3, clamping surface 4, limiting rib 5, clamping element 6, limiting post 7, limiting groove 8, guide groove 9, insertion groove 10, screw hole 11, and shaft hole 12, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
