[0002] CNC blades are the general term for indexable turning blades, and 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. CNC blades are the general term for indexable turning blades, and 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. There are four types of CNC blades: integral, inlaid, shock-absorbing, and special types. During the use of CNC blades, the commonly used back angles are 0°, 5°, 7°, and 11°, but each blade with a different back angle is an independent whole. When in use, it is necessary to replace the blade to perform cutting operations with different back angles. The workload of disassembly and replacement is large. At the same time, different independent blades are produced according to different back angles, which will increase the cost of use.

[0003] In summary, the utility model solves the existing problems by designing an adjustable CNC blade. Utility Model Content

However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0021] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this article includes any and all combinations of one or more related listed items.

[0023] For examples, see Figure 1-4 , the utility model provides a technical solution:

[0024] An adjustable CNC blade comprises a handle 1, a positioning frame 2 whose bottom is fitted with the top of the handle 1, and a rotating shaft is provided at the bottom of the positioning frame 2 to form a rotational connection with the top of the handle 1, a positioning groove 101 is provided at the bottom of one end of the positioning frame 2 at the top corner of the handle 1, a CNC blade 5 is placed inside the positioning groove 101, a groove is provided at the center of the inner bottom of the positioning groove 101, a sleeve 7 is installed inside the groove, a support rod 8 at the bottom of the sleeve 7 passes through the bottom of the handle 1 and is fixedly connected with the top of a push block 9, and a spring 10 is sleeved on the outer ring surface of the support rod 8 and can slide up and down.

[0025] For example, please refer to Figure 1 , Figure 2 and Figure 3A circular hole groove 201 is provided at one end of the top of the positioning frame 2, and a first step groove 3 is provided at the inner bottom of the circular hole groove 201. A hexagonal bolt 4 is installed on the inner side of the circular hole groove 201 at the top of the first step groove 3. After the hexagonal bolt 4 is tightened, its top is flush with the top edge of the circular hole groove 201. The angles of the back angles of the four edges of the CNC blade 5 are 0°, 5°, 7° and 11° respectively, and the top of the CNC blade 5 is square and each side is perpendicular to the top plane. The inner space size of the positioning groove 101 is a cube. After the CNC blade 5 is placed inside the positioning groove 101, the position of the back angle of the CNC blade 5 will not change.

[0026] The threaded hole 501 and the hexagonal bolt 4 can be threadedly connected to fix the CNC blade 5, and the bottom edge of the second step groove 6 coincides with the top edge of the sleeve 7. After the bolt is inserted into the second step groove 6, it is threadedly connected to the inside of the sleeve 7, and the thickness of the bolt cap will not affect the tightening degree of the hexagonal bolt 4.

[0027] For example, please refer to Figure 1 , Figure 2 and Figure 4 The sleeve 7 can rotate inside the groove opened at the inner bottom of the positioning groove 101, and the outer ring surface of the sleeve 7 fits with the inner side surface of the groove. After the sleeve 7 is placed in the groove, its top is flush with the top edge of the groove. The bottom of the support rod 8 passes through the inner bottom of the groove and the bottom of the tool handle 1 and is fixedly connected to the top of the push block 9, and the support rod 8 can rotate freely. The top of the spring 10 is fixedly connected to the bottom of the tool handle 1. The bottom of the spring 10 squeezes the push block 9 so that the sleeve 7 is completely received in the inner side of the groove, and after pushing the push block 9 up, the sleeve 7 can be completely separated from the groove.

[0028] The working process of the utility model is as follows: when using an adjustable CNC blade designed by the present invention, when installing the CNC blade 5 on the tool handle 1 of the CNC machine tool during the use of the CNC machine tool, the CNC blade 5 is first placed in the positioning groove 101, and then a bolt is inserted into the second step groove 6 and threadedly connected with the inside of the sleeve 7. At this time, the positioning frame 2 is rotated, and the hexagonal bolt 4 is inserted into the inner side of the circular hole groove 201, and the bottom screw rod passes through the first step groove 3 and is connected with the threaded hole 50101 on the top of the CNC blade 5. At this time, the CNC blade 5 can be used for processing operations. When a CNC blade with a different back angle is required, When operating, it is only necessary to unscrew the hexagonal bolt 4, rotate the positioning frame 2, and then push the push block 9 upwards to lift the CNC blade 5 through the sleeve 7. Since the angles of the four edge back angles of the CNC blade 5 are 0°, 5°, 7° and 11° respectively, the CNC blade 5 with different back angles can be rotated to the processing position according to needs, and then the above installation operation can be repeated to switch the CNC blade 5 with completely different back angles. There is no need to replace the CNC blade 5 as a whole, and only different back angles need to be adjusted, thereby effectively reducing the use cost of the CNC blade 5 and improving the switching efficiency of the blade.

[0029] In summary, the device can effectively reduce the use cost of CNC blades and improve the switching efficiency of blades.
