[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides Figure 1-4 The thread insert with chip removal groove shown in the figure comprises an insert body 1 . The top cross-section of the insert body 1 is arranged in a triangular shape. Cutting edges 101 are arranged on multiple ends of the insert body 1 .

[0025] It should be noted that the setting angle of the cutting edge 101 is determined according to the actual cutting state, and its inclination angle is between 7°-21°. The triangular main structure shape is adopted because the existing machine tools mostly use triangular grooves for the installation of threaded inserts. When the insert is installed, one end with the cutting edge 101 is exposed, and the insert will be stuck in the triangular groove, and the inner wall of the groove and the side wall of the insert body 1 will form a mutual obstruction, so that the cutting edge 101 can complete the cutting of the workpiece thread.

[0026] Also includes:

[0027] A chip guard structure is provided at the top of the blade body 1 and is located near the end of the cutting edge 101;

[0028] Specifically, the chip blocking structure includes a chip blocking protrusion 102, which is opened at the end of the top of the blade body 1. The chip blocking protrusion 102 is set to a "W" shape, and the outer protruding end of the chip blocking protrusion 102 is set in the same direction as the cutting edge 101.

[0029] It should be noted that the chip blocking protrusion 102 is set to a "W" shape so that when the cutting edge 101 cuts the workpiece, the chips cut off the workpiece are supported by the outer convex end of the chip blocking protrusion 102 and then diverted along the two sides and the middle, so that the chips can be easily removed.

[0030] The chip removal structure is provided at the top of the blade body 1 and is located between the cutting edge 101 and the chip blocking structure. The chip removal mechanism is used to discharge and guide the cutting debris by cooperating with the chip blocking structure. The chip removal structure is opened between the chip blocking protrusion 102 and the cutting edge 101;

[0031] Specifically, the chip removal structure includes a first chip removal groove 103 . The first chip removal groove 103 is opened at the top of the insert body 1 and is located between the outer convex end of the chip blocking protrusion 102 and the cutting edge 101 . The first chip removal groove 103 is configured to be wavy.

[0032] Furthermore, the chip removal mechanism also includes a plurality of second chip removal grooves 104 , which are symmetrically opened at the end of the top of the blade body 1 with the cutting edge 101 as the center, and the second chip removal grooves 104 are opened close to the inner concave surface of the chip blocking protrusion 102 .

[0033] It should be noted that the middle height of the first chip groove 103 gradually decreases towards both sides, so that the workpiece chips blocked by the convex end of the chip blocking protrusion 102 will first be blocked to the middle of the first chip groove 103, and then the chips will be discharged along the two ends of the first chip groove 103 according to the characteristics of the first chip groove 103, and the end of the second chip groove 104 close to the middle of the blade body 1 is higher than the end close to the side of the blade body 1, so that the workpiece chips blocked at the concave end of the chip blocking protrusion 102 can be discharged by the second chip groove 104.

[0034] The fastening mechanism is arranged at the top end of the blade body 1 and is used for fastening the blade body 1 after it is fixed on the machine tool.

[0035] Specifically, a fastening groove 105 is provided in the middle of the top of the blade body 1, and the fastening groove 105 is used to accommodate the fastening mechanism. A mounting hole 106 is provided in the middle of the bottom of the fastening groove 105 and passes through the blade body 1. The fastening mechanism includes a fastening cover plate 2, and the fastening cover plate 2 is arranged in the fastening groove 105. A hexagonal groove 201 is provided in the middle of the fastening cover plate 2.

[0036] Furthermore, a plurality of docking slots 107 are provided around the sides of the bottom end of the fastening groove 105, and the plurality of docking slots 107 are used to connect the fastening cover 2. A plurality of docking pins 202 are provided around the sides of the bottom end of the fastening cover 2, and the plurality of docking pins 202 are respectively connected with the plurality of docking slots 107 through-and-through.

[0037] It should be noted that when the blade is fixed, a fastening bolt is required to pass through the mounting hole 106. At this time, the nut of the fastening bolt will be placed in the fastening groove 105, and the nut of this type of fastening bolt is mostly hexagonal. After the fastening bolt fixes the blade body 1, the hexagonal groove 201 of the fastening cover 2 is aligned with the nut of the fastening bolt, and the interlacing cooperation between the docking column 202 and the docking slot 107 is utilized to block the fastening bolt with the sleeve by the fastening cover 2, thereby avoiding the fastening bolt from loosening during the operation of the blade body 1 and ensuring the stable operation of the blade body 1.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
