[0003] A search revealed that CN209255866U discloses a dovetail cutter structure, belonging to the field of dovetail cutter technology. The cutter head is the main body, with a first cutting edge and a second cutting edge. The first cutting edge has a first cutting section and a first cutting tip section, and the second cutting edge has a second cutting section and a second cutting tip section. This dovetail cutter structure reduces heat generated by friction during cutting, enables rapid cutting through the first and second cutting tip sections, and facilitates chip removal through chip evacuation grooves, thereby extending the service life of the dovetail cutter.

Detailed Implementation

[0018] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Example 1: Please refer to Figures 1-3 This is the first embodiment of the present invention, which provides a staggered tooth distributed drag-reducing dovetail cutter, comprising: The tool body 1, through hole 3, and limiting seat 5 are provided. The through hole 3 is evenly distributed on the circumferential surface of the tool body 1. The limiting seat 5 is symmetrically fixed on the top circumferential surface of the cutter body 1; Cutting assembly 2, connecting assembly 4, and cooling assembly 6; Cutting assembly 2 is located at the bottom end of the tool body 1; Connecting component 4 is located at the top of the cutter body 1; The cooling component 6 is located on the top circumferential surface of the cutter body 1.

[0021] Specifically, the cutting assembly 2 includes a spiral blade 21, a cutting blade 22, a first cutting edge 221, a second cutting edge 222, a conical groove 23, and a cooling groove 24. The spiral blade 21 is fixed to the bottom end of the cutter body 1. The cutting blade 22 is uniformly fixed on the circumferential surface of the bottom end of the spiral blade 21. The cutting blade 22 has a conical structure. The first cutting edge 221 is provided on the circumferential surface of the cutting blade 22. The second cutting edge 222 is provided at the bottom end of the cutting blade 22. The conical groove 23 is provided at the center of the bottom end of the cutting blade 22. The cooling groove 24 is provided on the inner side of the cutting blade 22.

[0022] Furthermore, the structure of the spiral blade 21 prevents the discharge of cutting chips during the cutting process, thereby preventing the cutting chips from affecting the cutting process of the dovetail cutter.

[0023] In use, the blade body 1 drives the spiral blade 21 and the cutting blade 22 to rotate. The first blade 221 cuts the side of the dovetail groove, and the second blade 222 cuts the bottom surface of the dovetail groove. The adjacent first blades 221 are staggered, and the second blades 222 on the bottom side are also staggered. This reduces the contact area during cutting, and prevents the blades from overheating and increasing wear without affecting the cutting process. This makes the dovetail cutter easier to use.

[0024] In summary, through the structure of the cutting assembly 2, cutting is performed by the cutting blades 22 uniformly fixed on the circumferential surface of one end of the blade body 1. The first cutting edge 221 on the circumferential surface of the cutting blade 22 and the second cutting edge 222 at the bottom are staggered, which can reduce the contact area of ​​each cutting blade 22 during cutting, thereby reducing the heat generated by each cutting blade 22 during cutting, preventing high temperature and increased wear, improving the processing quality of the dovetail cutter, and making it easier to use.

[0025] Example 2: Please refer to Figures 4-5 This is the second embodiment of the present utility model.

[0026] Specifically, the connecting component 4 includes a connector 41 and a fixing groove 42. The connector 41 is fixed on the top side of the blade body 1. The connector 41 has a rectangular structure. The fixing grooves 42 are symmetrically opened on both sides of the connector 41, and the fixing grooves 42 are located at the center of the side of the connector 41.

[0027] Furthermore, the rectangular connector 41 allows for quick assembly and disassembly of the cutter body 1, thereby improving the processing efficiency of the dovetail cutter.

[0028] Specifically, the cooling assembly 6 includes a housing 61, a cavity 62, a conduit 63, a sealing groove 64, and a sealing ring 65. The housing 61 is fastened to the inner side of the limiting seat 5. The cavity 62 is opened on the inner side of the housing 61. The housing 61 is fastened to the circumferential surface of the through hole 3. The conduit 63 is fixed on the circumferential surface of the housing 61. The conduit 63 communicates with the cavity 62 inside the housing 61. The sealing groove 64 is symmetrically opened on the inner side of the limiting seat 5. The sealing ring 65 is fixed on the inner side of the sealing groove 64.

[0029] Furthermore, the structure of the housing 61 allows for cooling of the cutter body 1 without affecting its cutting operations, thereby extending the service life of the dovetail cutter.

[0030] In use, with the cooperation of the fixing groove 42, the connector 41 is fixedly connected to the cutting equipment. At this time, the cutting equipment can drive the cutter body 1 to rotate with the cooperation of the connector 41, thereby performing cutting processing. At this time, the conduit 63 is connected to the coolant delivery pipe to deliver coolant to the inside of the housing 61. With the cooperation of the sealing groove 64 and the sealing ring 65, coolant is delivered to the inside of the cutter body 1 without affecting its rotation. It is delivered through the through hole 3 to the cooling groove 24 inside the cutter body 1 and sprayed out from the cutting position at one end of the cutter body 1. In this way, the cutting position of the cutter body 1 is cooled during the cutting process to prevent it from overheating and to extend the service life of the dovetail cutter.

[0031] In summary, through the structure of the connecting component 4 and the cooling component 6, the dovetail cutter can be quickly disassembled and replaced via the connector 41. Coolant is delivered to the inside of the cooling tank 24 through the housing 61, which can prevent the temperature at the cutting position of the cutter body 1 from being too high, thereby reducing wear and extending the service life of the dovetail cutter.

[0032] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
