[0035] It should be noted that the chamfering tool of the application needs to be used in combination with a machining machine tool, and the chamfering tool is installed on the main shaft of the machining machine tool, and the handle 1 is driven to rotate by the main shaft (not shown) of the machine tool;During machining, the handle 1 drives the tool body 2 to rotate synchronously, and the tool particle 3 and the assembly groove 21 are in a fixed connection relationship, so that the tool particle 3 can rotate synchronously with the tool body 2;When the tool particle 3 touches the end of the part to be machined 100, the tool disc 4 abuts against the surface of the part to be machined 100, in this case, the tool particle 3 and the tool disc 4 contact the part to be machined 100 together, forming two contact areas above and below, so that the part to be machined 100 is stressed in the two contact areas, avoiding the fine vibration of the part to be machined 100 due to the stress concentrated in a certain area, thereby reducing the problem of stress concentration due to uneven chamfer surface caused by vibration;In this way, the quality of the chamfer and the service life of the part are improved.

[0036] Referring to Figure 1 And Figure 2 The handle 1 comprises a first handle part 11 and a second handle part 12, the first handle part 11 is a cylindrical structure, the first handle part 11 is arranged at one end of the second handle part 12 and is fixedly connected with the second handle part 12 coaxially, or the first handle part 11 and the second handle part 12 are integrally formed;The second handle part 12 is also a cylindrical structure, the diameter of the first handle part 11 is smaller than the diameter of the second handle part 12, and the other end of the second handle part 12 is fixedly connected with the tool body 2 coaxially.

[0037] Referring to Figure 3 And Figure 4The cutter body 2 is provided with an assembly groove 21, the assembly groove 21 is provided with an assembly surface 211, preferably the assembly surface 211 is a plane; the assembly surface 211 is provided with a mounting groove 2111, the mounting groove 2111 is a groove, the cutter grain 3 is arranged in the mounting groove 2111, and the assembly surface 211 is further provided with a mounting hole 2112 for fixing the cutter grain 3.

[0039] Referring to Figure 5 and Figure 6 , the end surface of the cutter body 2 close to the cutter disc 4 is further provided with a first connecting hole 23, the first connecting hole 23 is a blind hole, a rotating column 24 is arranged in the first connecting hole 23, the rotating column 24 is a hollow cylindrical structure, the rotating column 24 is provided with internal threads, and the rotating column 24 is rotatably connected with the cutter body 2 through a bearing, and the rotating column 24 is used for connecting the cutter disc 4.

[0040] Referring to Figure 5 , Figure 7 and Figure 8 , the cutter disc 4 is arranged at the bottom of the cutter body 2, and the cutter disc 4 is a disc type structure; a guide groove 41 is arranged on the end surface of the cutter disc 4 close to the cutter body 2, and the guide groove 41 is a circular annular groove; the guide groove 41 is used for fine adjustment of the angle of the cutter grain 3, and the guide groove 41 is used for guiding the cutter grain 3; specifically, when the cutter grain 3 has been installed on the cutter body 2, the angle of the cutter grain 3 cannot be completely consistent due to manual installation, and therefore the guiding of the cutter grain 3 can be realized by means of the process of installing the cutter disc 4; specifically, when the cutter disc 4 is installed, in the initial stage, the guide groove 41 abuts against the cutter grain 3, when the cutter disc 4 is further fastened, the cutter disc 4 will move upward, at this time, all the cutter grains 3 will also be adjusted to a uniform angle under the pressure of the surface of the guide groove 41, thereafter, the cutter grain 3 is further fastened by the fixing piece 31, that is, the positioning work of the cutter grain 3 is completed; at the same time, after the cutter disc 4 adjusts the cutter grain 3 to a suitable angle, the guiding purpose is completed, and the cutter disc 4 can move in the opposite direction to generate a certain gap with the cutter grain 3, in this way, the cutter disc 4 does not contact the cutter grain 3, and damage of the cutter disc 4 caused by relative movement between the cutter disc 4 and the cutter grain 3 in the machining process is avoided.

[0041] As described above, the guide groove 41 of the tool disc 4 affects the installation position of the tool grain, which affects the shape of the contact surface with the part to be machined 100, thereby affecting the shape of the chamfer, so the tool disc 4 is important in the design of the chamfer tool, and various specifications of the guide groove 41 can be designed according to different chamfer requirements; according to the chamfer machining requirement, different specifications of the tool disc 4 can be replaced to meet the requirement of different chamfer sizes, thereby avoiding frequent replacement of the tool grain 3, thereby affecting the stability and durability of the overall tool.

Specifically, when the main shaft drives the chamfer tool to rotate, the tool grain 3 cuts the workpiece at a certain linear speed; the feeding movement makes the tool grain 3 move along the edge of the part to be machined 100, and at the same time, the tool disc 4 contacts the part to be machined 100, thereby realizing continuous chamfer machining, the tool grain 3 and the tool disc 4 of the utility model contact the part to be machined 100 at the same time, so that the part to be machined 100 is stressed at multiple places, thereby reducing the slight vibration generated in the machining process, thereby reducing the problem of stress concentration, thereby improving the quality of the chamfer.
