[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] Reference Figure 1 and Figure 3 The utility model provides an embodiment: a tapered ball-end cutter, comprising a fixed disc 1, a fixed column 3 is fixedly connected to the right side of the fixed disc 1, an annular cutter 4 is fixedly connected to the outer wall of the fixed column 3, a cutter disc 5 is fixedly connected to the right side of the fixed column 3, a plurality of cutter tips 6 are fixedly connected to the right side of the cutter disc 5 at equal intervals, a groove 7 is provided on the outer wall of the plurality of cutter tips 6, a plurality of chip removal grooves 8 are provided at equal intervals on the right side of the cutter disc 5, a tool handle 10 is provided on the left side of the fixed disc 1, and a disassembly mechanism 2 is provided on the right side of the tool handle 10;
[0034] Specifically, the annular tool 4 is fixed by the outer wall of the fixed column 3. The key to this design is that there are unequal helix angles between the fixed column 3 and the annular tool 4. This innovation makes the processing process more efficient and stable. In the traditional processing process, the high-frequency resonance phenomenon often leads to a decrease in processing accuracy and may even affect the safe operation of the processing equipment. By setting unequal helix angles between the fixed column 3 and the annular tool 4, the occurrence of this phenomenon can be effectively reduced, thereby ensuring the smooth progress of the processing process. In addition, in order to further improve the processing efficiency, the design also sets a plurality of grooves 7 on the annular tool 4. These grooves 7 can increase the chip removal and chip capacity of the ball head cutter, so that the processing process can be carried out more efficiently. During the processing process, the timely discharge of debris is also an important factor affecting the processing efficiency. To this end, the designer sets a plurality of chip removal grooves 8 on the surface of the annular tool 4 to facilitate the smooth discharge of debris.
[0035] Reference Figure 1 and Figure 2 The disassembly mechanism 2 includes a rotating column 201 and a rotating assembly. The adjacent sides of the two rotating columns 201 are respectively rotatably connected to the upper and lower sides of the handle 10. The rotating assembly is arranged on the left side of the fixed disk 1. The opposite sides of the rotating columns 201 are fixedly connected with a locking plate 202. The adjacent sides of the two locking plates 202 are fixedly connected with a clamping block 203. The upper and lower sides of the fixed disk 1 are provided with a clamping groove 204. The adjacent sides of the two clamping blocks 203 are respectively engaged with the corresponding clamping grooves 204; the rotating assembly includes a threaded column 205. The left side of the fixed disk 1 is fixedly connected with the threaded column 205. The middle part of the right side of the handle 10 is provided with a threaded groove 206. The left end of the threaded column 205 is threadedly connected to the threaded groove 206. The right side of the outer wall of the handle 10 is fixedly connected with a sealing ring 9.
[0036] Specifically, the rotation control of the rotating column 201 is achieved by flipping the two locking plates 202. During this operation, the engaging block 203 is fixed on one side of the two locking plates 202 and plays a key role. Its task is to disengage the corresponding engaging groove 204. The purpose of this operation step is to rotate the fixed disk 1. When the fixed disk 1 rotates, the threaded column 205 is separated from the threaded groove 206 on the right side of the tool handle 10. This separation process is necessary because it allows the tool handle 10 to be completely separated from the fixed disk 1, which makes the disassembly and replacement of the cutter head very convenient, thereby improving the flexibility of the ball-end cutter.
[0037] Reference Figure 1 , Figure 2 and Figure 3The outer walls of the two engaging blocks 203 are fixedly connected with rubber rings 14; the diameter of the handle 10 is larger than the diameter of the annular cutter 4; the outer wall of the annular cutter 4 is provided with Balzers AN coating; the left side of the handle 10 is fixedly connected with a hook 12, and the left side of the outer wall of the handle 10 is provided with an arc surface;
[0038] Specifically, the rubber ring 14 improves the engagement effect between the engagement block 203 and the engagement groove 204 , the Balzers AN paint increases the service life of the annular cutter 4 , and the hook 12 facilitates the storage of the ball-end cutter.
[0039] Reference Figure 1 , an indicator mark 13 is fixedly connected to the front side of the fixed disk 1; the rotation direction of the plurality of chip removal grooves 8 is right-hand spiral, and the rotation direction of the annular tool 4 is right-hand spiral; a rubber sleeve 11 is fixedly installed in the middle of the outer wall of the tool handle 10;
[0040] Specifically, the indicator mark 13 makes it easy to install the ball knife, and the rubber sleeve 11 increases the static friction of the knife handle 10, thereby facilitating use.
[0041] Working principle: The annular tool 4 fixed by the outer wall of the fixed column 3 and the unequal helix angles of the fixed column 3 enable efficient and smooth processing, thereby reducing the high-frequency resonance phenomenon during processing, and the multiple grooves 7 enable the ball-end cutter to increase the chip removal and cutting capacity to achieve the purpose of efficient processing, and the multiple chip removal grooves 8 facilitate the discharge of debris, and by flipping the two locking plates 202, the locking blocks 203 fixed on one side of the two locking plates 202 are respectively disengaged from the corresponding locking grooves 204 when the rotating column 201 rotates, and then the fixed disk 1 is rotated to separate the threaded column 205 from the threaded groove 206 on the right side of the tool handle 10, and then the tool handle 10 is separated from the fixed disk 1, making it easy to disassemble and replace the tool head, thereby improving the flexibility of the ball-end cutter.
[0042] 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 substitutions for some of the technical features therein.
