[0002] Alloy CNC blades are the mainstream products in the field of modern metal cutting applications. They are mainly used in metal turning, milling, cutting and grooving, thread turning and other fields. Alloy CNC blades can play a key role in metal processing and adapt to different processing needs, such as turning, machine tool processing, composite material processing, high-precision processing, etc. They are also widely used in wood processing and plastic processing. They can perform cutting, grooving, engraving and other operations. Alloy CNC blades are characterized by high efficiency and high wear resistance, and their processing efficiency is more than 4 times higher than that of traditional welding blades and alloy blades.

[0003] In the prior art, a non-standard carbide threaded insert for a CNC machine tool disclosed in announcement number CN210731273U includes a insert body, a serrated thread and an installation opening, and a convex plate body is installed above the middle of the insert body, and the convex plate body and the insert body are an integrated structure.

[0004] However, in actual use, when the non-standard carbide threaded insert for the CNC machine tool is used, the convex plate body is fixedly installed on the insert body, and the serrated thread and the insert body are also fixedly installed. Therefore, when the serrated thread on the outer side of the insert body is replaced after long-term use, the insert body and the convex block body can only be replaced as a whole, which is a waste of materials. Utility Model Content

Therefore, during the use of the blade body, when the serrated thread on the outer side of the blade body is replaced after long-term use, only the blade body and the convex block body can be replaced as a whole, which is a waste of materials.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: an alloy CNC blade with a chip breaker groove, comprising a blade body, a plurality of mounting grooves arranged outside the blade body and a fixing assembly arranged inside the mounting groove, wherein a cutting blade is inserted in the middle of the fixing assembly;

[0007] The fixing assembly comprises a limiting rod, the top end of which passes through the mounting groove, an elastic plate is fixedly mounted on the top end of the limiting rod, and a tension spring is sleeved on the outer side of the limiting rod.

[0008] As a further solution of the utility model: a slot matching the limit rod is provided at the connection between the installation slot and the limit rod, the slot is provided on the installation slot, and a fixing bin matching the elastic plate is provided at the connection between the installation slot and the elastic plate, the fixing bin is provided on the blade body.

[0009] As a further solution of the utility model: one end of the tension spring is fixedly installed on the elastic plate, and the other end is fixedly installed inside the fixed bin.

[0010] As a further solution of the utility model: one end of the tension spring is fixedly installed on the elastic plate, and the other end is fixedly installed inside the fixed bin.

[0011] As a further solution of the utility model: bumps are fixedly mounted on both sides of the top of the cutting blade and the blade body, and chip breaking grooves are arranged in the middle of the two groups of bumps.

[0012] As a further solution of the utility model: a mounting opening is provided in the middle of the blade body.

[0013] As a further solution of the utility model: the outer sides of the blade body and the cutting blade are coated with an AlCrN coating.

[0014] The beneficial effects of the utility model are:

[0015] 1. The elastic plate of the assembly is manually fixed so that the elastic plate pulls the tension spring and the limit rod below out of the slot on the blade body, and then the cutting blade can be inserted into the inside of the installation slot. Then, the elastic plate is loosened so that the tension spring below the elastic plate rebounds to the position of the limit rod, and the limit rod is inserted into the limit slot of the cutting blade, so as to achieve the effect of detachable replacement of the cutting blade and avoid material waste during replacement.

[0016] 2. The protrusions are fixed protrusions. During the use of the blade body and the cutting disc, the protrusions on both sides of the blade body can lift the waste chips at the cutting workpiece through the chip breaking grooves on the inner side. In this way, the waste chips can be quickly separated from the workpiece by the lifting of the protrusions, thereby achieving the chip breaking effect. BRIEF DESCRIPTION OF THE DRAWINGS
