[0029] like Figures 1 to 4As shown, the dial processing magic drill according to the embodiment of the utility model includes: a cutter body 100, a connecting portion 110 is provided on the cutter body 100, and the connecting portion 110 is used to connect with the dial processing equipment, a first positioning groove 120 is provided on the cutter body 100, and the first positioning groove 120 is arranged at the lower end of the cutter body 100 along the axis of the cutter body 100, and the first positioning groove 120 is cylindrical, and a plurality of fixing grooves 130 are arranged on the side of the cutter body 100, and the plurality of fixing grooves 130 are uniformly distributed along the axial direction of the cutter body 100; a cutter head 200, a cutter tip 210 is provided at the lower end of the cutter head 200, and the cutter tip 210 is conical, and the cutter head 200 is provided with a cutter tip 210. A first positioning column 220 is arranged at the upper end of the head 200. The first positioning column 220 is arranged along the axis of the cutter head 200. The first positioning column 220 is cylindrical. The diameter of the first positioning column 220 is the same as the diameter of the first positioning groove 120. A plurality of fixing blocks 230 are arranged on the side of the cutter head 200. The plurality of fixing blocks 230 correspond to the plurality of fixing grooves 130 one by one. The first positioning column 220 cooperates with the first positioning groove 120 to limit the axial and radial translation of the cutter head 200 along the cutter body 100. The plurality of fixing blocks 230 cooperate with the plurality of fixing grooves 130 to limit the axial rotation of the cutter head 200 around the cutter body 100.

[0030] Insert the cutter head 200 into the cutter body 100 along the axial direction of the cutter body 100. At this time, the first positioning column 220 and the first positioning groove 120 are embedded together to ensure that the cutter head 200 is installed at the axial center position of the cutter body 100 to prevent the cutter head 200 from shaking during rotation due to eccentric installation. After the cutter head 200 is installed in place axially, rotate the cutter head 200 along the circumference of the cutter body 100 so that the fixing block 230 is inserted into the fixing groove 130, and the positioning of the cutter head 200 along the circumferential rotation of the cutter body 100 is completed, so that the cutter head 200 rotates with the cutter body 100 to realize drilling, grooving and other processes.

[0031] Thus, the cutter head 200 and the cutter body 100 are designed in a split type, and the axial and radial positioning of the cutter head 200 is completed by the cooperation between the first positioning groove 120 and the first positioning column 220, and the circumferential positioning of the cutter head 200 is completed by the cooperation between the fixing block 230 and the fixing groove 130. Thus, the cutter head 200 can be conveniently replaced, and the cutter head 200 is accurately positioned and reliably fixed on the cutter body 100.

[0032] like Figures 1 to 4As shown, the cutter body 100 is provided with a chip removal groove 300, and the chip removal groove 300 includes a first chip removal segment 310 and a second chip removal segment 320. The first chip removal segment 310 is located at the lower end of the cutter body 100, and the first chip removal segment 310 is spirally arranged on the cutter body 100. The second chip removal segment 320 is located at the upper end of the cutter body 100, and the second chip removal segment 320 is arranged on the cutter body 100 in the vertical direction. A connecting portion 110 is provided at the upper end of the cutter body 100, and the cutter body 100 is connected to the processing equipment through a magic drill. Two chip removal grooves 300 are evenly distributed along the circumference of the cutter body 100. The upper end of the chip removal groove 300 is the second chip removal segment 320, and the second chip removal segment 320 is arranged outside the cutter body 100 in the up-down direction. The lower end of the chip removal groove 300 is the first chip removal segment 310, and the first chip removal segment 310 is spirally surrounded on the outside of the cutter body 100.

Through the cooperation between the second positioning groove 140 and the second positioning column 240, the cutter head 200 is further positioned to ensure that the cutter head 200 is installed at the axis center position of the cutter body 100, to avoid the cutter head 200 from shaking during the rotation process, and to improve the processing accuracy of the dial processing magic drill.

[0034] like Figure 3 and Figure 4 As shown, the opening direction of the fixing groove 130 is the same as the rotation direction of the cutter body 100, and the protruding direction of the fixing block 230 is opposite to the rotation direction of the cutter body 100. Therefore, during the rotation of the cutter body 100, the force applied by the material to be processed to the cutter head 200 will press the cutter head 200 against the cutter body 100, so that the connection between the cutter head 200 and the cutter body 100 is tight and stable, preventing the cutter head 200 from shaking or falling during the processing.

[0035] like Figure 3 and Figure 4 As shown, a snap-fit ​​groove 150 is provided in the fixing groove 130, and a snap-fit ​​portion 250 is provided at a corresponding position of the fixing block 230. When the fixing groove 130 and the fixing block 230 are in place, the snap-fit ​​groove 150 and the snap-fit ​​portion 250 are snap-fitted with each other. The blade body 100 and the blade head 200 are further locked by snapping. The blade head 200 can be easily inserted into the blade body 100 for snap-fitting. After being inserted into place, the blade head 200 is firmly fixed and will not loosen during use. The blade head 200 can be quickly and firmly fixed, and the blade head 200 can be easily replaced.

[0036] like Figure 3 and Figure 4 As shown, a first magnetic attraction portion 160 is also provided in the fixing groove 130, and a second magnetic attraction portion 260 is provided at a corresponding position of the fixing block 230, and the first magnetic attraction portion 160 and the second magnetic attraction portion 260 attract each other. The fixing block 230 is automatically adsorbed to the fixing groove 130 by magnetic attraction, which can ensure that the cutter head 200 is installed in place and is not easy to loosen. In addition, the installation and removal of the cutter head 200 does not require additional screwing or locking steps, and the operation is quick and easy.

[0037] like Figure 3 to Figure 4 As shown, the cutter body 100 is further provided with a coolant channel 400, which is arranged in the cutter body 100 along the axial direction of the cutter body 100, and the outlet of the coolant channel 400 is arranged toward the cutter head 200. The coolant is directly supplied to the cutter head 200 through the coolant channel 400, so as to cool the drill bit and prevent the chips from being welded to the cutter tip 210, thereby helping the chips to be discharged quickly.

[0038] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
