Description

Technical Field

[0001] The utility model relates to the technical field of end mills, in particular to a diamond multi-edge end mill for machining aviation composite materials. Background Art

[0002] End mill is a cutting tool commonly used in CNC machine tools and manual milling machines, mainly used for milling planes, contours, slots and cavities, etc. The cutting edge of the end mill is perpendicular to the direction of its axis, hence the name "end mill". In the prior art, the end mill is clamped by a clamping assembly and then driven to rotate by a rotating assembly, so that the end mill can cut the object.

[0003] In order to meet the requirements of high speed and high rigidity, traditional end mills generally adopt a one-piece carbide molding structure. However, when processing aviation composite materials, their service life is short and frequent tool changes lead to reduced processing efficiency. Moreover, due to the linear speed requirements of carbide tools, machine tools cannot fully exert the advantages of high-speed milling. In addition, the clamping assembly clamps and fixes the end mill, and the surface of the end mill may slip against the clamping assembly, affecting its use. Utility Model Content

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] The utility model provides a diamond multi-blade end mill for machining aviation composite materials, comprising a cutter body, a cutter blade groove is provided at the front end of the cutter body, a cutter blade is fixedly arranged in the cutter blade groove; a plug-in limiter and a reinforcing rod are provided at the rear end of the cutter body; a first magnet is provided on the rear end surface of the cutter body, and a second magnet is provided on the plug-in limiter and the reinforcing rod.

[0007] Furthermore, the blade body is made of cemented carbide, the blade is made of diamond, and the blade is fixed on the blade groove by vacuum welding.

[0008] Furthermore, the blade extends to the outside of the blade groove, and the bottom of the blade is provided with a chamfer.

[0009] Furthermore, a chip discharge groove is provided in the blade groove for discharging waste chips generated by blade cutting.

[0010] Furthermore, a clamping seat is provided at the rear end of the cutter body for clamping and fixing the cutter body and fixing it to the machine tool. A plug hole is provided on the clamping seat, and the rear end of the cutter body is plug-fitted with the plug hole.

[0011] Furthermore, the plug-in limiter and the reinforcing rod are both inserted on the inner bottom of the plug-in hole; the cross-section of the plug-in limiter is polygonal, and the reinforcing rods are arranged in four numbers, and the four reinforcing rods are arranged in a matrix around the outside of the plug-in limiter.

[0012] The beneficial effects of the utility model are:

[0013] 1. By setting up a separately welded diamond blade, it has a longer service life than the integrated carbide blade, which can greatly reduce the number of tool changes and effectively improve the processing efficiency; the diamond blade can adapt to higher linear speeds, which can give full play to the advantages of high-speed milling of machine tools and improve processing efficiency.

[0014] 2. By setting the plug-in limit body and the magnet, a magnetic connection and a rotation limit are added between the cutter body and the clamping assembly, which effectively prevents the up and down relative sliding and relative rotation between the cutter body and the clamping assembly, ensuring the use effect; moreover, in the process of the magnet being pulled out, the debris in the installation chamber can also be adsorbed and brought out, which plays a certain cleaning role, further prevents wear and tear, and extends the service life.

The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0022] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated. Example

[0023] like Figure 1~Figure 5 As shown, a diamond multi-edge end mill for machining aviation composite materials includes a cutter body 1 made of cemented carbide, the diameter of the cutter body 1 is in the range of 8-32 mm, specifically, in order to further improve the cutting efficiency, the diameter of the cutter body 1 is 32 mm, further, the front end of the cutter body 1 is adapted to be provided with a blade groove 12, the number of the blade grooves 12 is set to 8-18 according to the diameter range of the cutter body 1, specifically, in order to adapt to the cutter body 1 with a diameter of 32 mm, thereby further improving the cutting efficiency, the blade grooves 12 are set to 16, preferably, in order to prevent chips The accumulation affects the cutting efficiency, and each blade groove 12 is connected to a chip groove 121; and each blade groove 12 is fixedly fitted with a blade 4. Preferably, in order to cut the side and bottom surfaces of the prefabricated hole, the side outer edge and the bottom outer edge of the blade 4 extend to the outside of the blade groove 12. Furthermore, in order to facilitate chamfering and reduce wear and extend the service life, the bottom of the blade 4 is provided with an arc-shaped chamfer. Furthermore, in order to solve the problems of short tool life and high-speed milling adaptation of machine tools, the blade 4 is made of diamond material and fixed by vacuum welding.

[0024] Through this solution, by setting up a separately welded diamond blade 4, it has a longer service life than an integrally set carbide blade, can greatly reduce the number of tool changes, and effectively improve the processing efficiency; the diamond blade is more adaptable to higher linear speeds, can give full play to the advantages of high-speed milling of machine tools, and improve processing efficiency.

[0025] Preferably, in order to cooperate with the rotational motion to more efficiently remove chips and cut, the chip removal groove 121 is configured as a structure that rises in a spiral from the bottom end of the tool body 1, and the blade 4 is also adapted.
