[0042] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0043] Referring to Figure 1 、 2 As shown in FIGS. 3, the chamfering tool includes a tool mounting seat 100 and a blade 300. The tool mounting seat 100 is provided with a connection channel 110 and a fixing channel 120. The connection channel 110 is used for the connecting rod 400 to pass through. One end of the fixing channel 120 is communicated with the connection channel 110. A fixing component 200 is provided at the end of the fixing channel 120 far from the connection channel 110. The fixing channel 120 is used for the fixing component 200 to pass through. The fixing component 200 is used to embed into a positioning groove (not marked in the figure) to fixedly connect the tool mounting seat 100 and the connecting rod 400. At least one blade mounting position 140 is provided on both sides of the tool mounting seat 100 near the two ends of the connection channel 110; there are at least two blades 300. Blades are provided on both opposite sides of each blade 300. Each blade mounting position 140 is provided with a mounting groove 141. The blade 300 can be embedded into the mounting groove 141 to be fixedly connected with the tool mounting seat 100.

[0044] In the above embodiment, through the cooperation of the connection channel 110 and the fixing channel 120 of the tool mounting seat 100, the connecting rod 400 can pass through stably and the fixing component 200 can be embedded into the positioning groove, realizing the firm connection between the tool mounting seat 100 and the connecting rod 400, reducing the probability of the chamfering tool detaching from the connecting rod 400 during the processing, and improving the safety. At least one blade mounting position 140 is provided on both sides of the tool mounting seat 100, and a mounting groove 141 is provided at the mounting position so that the blade 300 can be firmly embedded and fixed. Blades 300 are provided at the blade mounting positions 140 on both sides of the tool mounting seat 100, and effective cutting can be performed during both forward and backward movements, thereby realizing chamfering processing on the front and rear water channels of a multi-cavity template with blind holes. Compared with traditional single-direction chamfering tools, the embodiment of this application can complete the chamfering processing of the front and rear two water channels simultaneously in one feed process, greatly improving the processing efficiency, reducing the process conversion time, and reducing the need for repeated tool setting and tool changing.

[0045] In some embodiments, the blade 300 can be selected as a used cutting insert. Only the tip part of the used cutting insert is used in lathe machining, and the tip part has been worn. However, the side cutting edge of the used cutting insert can be used for chamfering machining. Therefore, using the used cutting insert as the blade 300 realizes resource recycling, meets the environmental protection requirements, reduces the production cost, does not require grinding, saves the machining time, and improves the machining efficiency.

[0046] It can be understood that, referring to Figure 3 、 4 As shown, the fixing component 200 includes a fixing nut 210, a positioning pin 220 and a spring 230. The fixing nut 210 is arranged at one end of the fixing channel 120 far from the connecting channel 110. The positioning pin 220 includes a positioning rod 221. The positioning rod 221 is arranged in the fixing channel 120 and passes through the fixing nut 210. One end of the positioning rod 221 close to the connecting channel 110 protrudes to form a positioning convex part 222. The positioning convex part 222 is used for embedding into the positioning groove. One end of the positioning convex part 222 far from the connecting channel 110 protrudes on the circumferential side to form a clamping convex part 223. One end of the spring 230 abuts against one end of the fixing nut 210 close to the connecting channel 110, and the other end of the spring 230 abuts against one end of the clamping convex part 223 close to the fixing nut 210. The fixing nut 210 is installed at one end of the fixing channel 120 far from the connecting channel 110, making the whole fixing structure more compact and facilitating assembly and adjustment. The positioning rod 221 in the positioning pin 220 passes through the fixing nut 210 and forms a positioning convex part 222 at one end close to the connecting channel 110. This convex part can be accurately embedded into the positioning groove on the connecting rod 400, thus ensuring the stable connection between the tool mounting seat 100 and the connecting rod 400 and preventing offset or vibration caused by loosening during the machining process. A clamping convex part 223 is provided at one end of the positioning convex part 222 far from the connecting channel 110, forming a reliable pre-tightening structure with the spring 230. One end of the spring 230 abuts against the fixing nut 210, and the other end abuts against the clamping convex part 223, making the positioning pin 220 always in an elastically stressed state, which helps to improve the connection stability, and at the same time facilitates installation, disassembly and replacement. The above embodiments not only ensure the high-rigidity connection of the tool, reduce the errors caused by loosening during the machining process, but also improve the convenience of tool replacement and installation, improve the machining efficiency, and enhance the durability of the overall structure.

[0047] It can be understood that, referring to Figure 4As shown, the fixing component 200 further includes a hand nut 240, and the hand nut 240 is connected to the end of the positioning rod 221 away from the connection channel 110. Through the cooperative action of the fixing nut 210, the hand nut 240, the positioning pin 220 and the spring 230, the fixing of the tool mounting seat 100 and the connecting rod 400 is more stable and convenient to adjust. The hand nut 240 is connected to the end of the positioning rod 221 away from the connection channel 110, enabling the operator to conveniently manually adjust or tighten and loosen the positioning pin 220 through the hand nut 240 without additional tools, improving the disassembly and assembly efficiency of the chamfering tool, and thus improving the chamfering processing efficiency at the end of the water delivery hole.

[0048] In some embodiments, in order to improve the connection stability and anti-loosening ability, the fixing component 200 can be provided with an anti-loosening washer and a locking spring 230 assembly. The fixing nut 210 can be a self-locking nut with a nylon locking ring inside to prevent loosening under high-frequency vibration conditions. In addition to embedding into the positioning groove on the connecting rod 400, the positioning convex portion 222 of the positioning pin 220 can be provided with a wedge-shaped locking design. When the positioning pin 220 is inserted, under the action of the spring 230, the positioning convex portion 222 can form a self-locking inclined plane structure to improve the anti-impact and anti-vibration ability. Moreover, an additional torsion spring structure is provided between the hand nut 240 and the positioning rod 221. The torsion spring can provide additional resilience after the hand nut 240 is loosened, enabling the positioning pin 220 to quickly return to its position, reducing the manual operation time and improving the processing continuity.

[0049] In some embodiments, in order to improve the disassembly and assembly efficiency, a quick-change locking mechanism can be introduced to achieve the quick disassembly and assembly of the tool mounting seat 100 without using tools. The fixing nut 210 can be replaced with a quick-change locking clip with a ball buckle structure inside. When the positioning pin 220 is inserted, it can be automatically locked, and when the hand nut 240 is rotated by a certain angle, the ball mechanism will loosen, allowing the positioning pin 220 to disengage from the positioning groove, thus quickly releasing the tool mounting seat 100. At the same time, the action of the spring 230 can ensure that the positioning pin 220 automatically springs into the positioning groove during assembly, achieving one-key locking without additional nut adjustment.

[0050] It can be understood that with reference to Figure 5As shown, three blade 300 mounting positions 140 are evenly distributed on both sides of the tool mounting seat 100 near both ends of the connecting channel 110, and six blades 300 are provided. Each blade 300 is embedded in the mounting groove 141 on the corresponding blade 300 mounting position 140 and fixedly connected to the tool mounting seat 100. The blades 300 located on both sides of the tool mounting seat 100 are evenly distributed, and the cutting force is evenly distributed at multiple points, which can effectively reduce the situation where a single point is subjected to excessive force, thereby reducing tool wear and increasing the service life of the blade 300. The multi-blade 300 structure helps to improve the quality of the processed surface and reduce burrs and chamfer size errors.

[0051] Understandably, referring to Figure 2 As shown, the blade 300 installation position 140 is further provided with a first groove 142, which is provided on the side of the blade 300 installation position 140 facing the fixing channel 120, and the first groove 142 is communicated with the installation groove 141. By providing the first groove 142 communicated with the installation groove 141, when the blade 300 needs to be replaced, there is a reserved space so that the blade 300 is more easily separated from the installation groove 141, thereby improving the efficiency of disassembling the blade 300.

[0052] For example, Figure 2 As shown, each mounting groove 141 is provided with two first grooves 142, and the two first grooves 142 are arranged on the side of the blade 300 mounting position 140 facing the fixed channel 120. When the blade 300 is embedded in the mounting groove 141, the two first grooves 142 can make the blade 300 close to the two corners of the tool mounting seat 100 and form a gap between the tool mounting seat 100. When the blade 300 needs to be replaced, the blade 300 can be more easily removed from the tool mounting seat 100, thereby improving the disassembly efficiency of the blade 300.

[0053] Understandably, referring to Figure 1 , 4 As shown, the cross section of the connecting channel 110 is set to a hexagon, and the cross section of the connecting rod 400 matches the cross section of the connecting channel 110, which can enhance the torsion resistance between the tool mounting seat 100 and the connecting rod 400, and ensure that no relative sliding or offset occurs during the high-load, high-speed rotation chamfering process. Compared with the traditional circular or square cross section, the hexagonal structure can provide more contact surfaces, effectively disperse the torque load, reduce stress concentration, and improve the stability and durability of the connection. In addition, this embodiment also has a self-alignment function. During the assembly process, the connecting rod 400 can be smoothly inserted into the connecting channel 110 and accurately positioned, reducing assembly errors and improving processing accuracy. At the same time, the direction of the tool can be ensured to be stable without an additional anti-rotation mechanism, simplifying the structural design and reducing manufacturing costs.

[0054] It is understandable that the blade 300 is detachably connected to the blade 300 mounting seat. The detachable connection design between the blade 300 and the tool mounting seat 100 enables the blade 300 to be quickly replaced after wear, extends the service life of the tool mounting seat 100, and reduces the overall maintenance cost. Since the blade 300 can be independently disassembled, there is no need to replace the entire tool mounting seat 100 when replacing the blade 300, thus reducing material waste and improving economy. The detachable connection method also facilitates daily cleaning and maintenance, preventing chip accumulation from affecting the machining quality.

[0055] In some embodiments, an elastic snap structure can be designed in the mounting groove 141 of the blade 300. One side of the blade 300 is provided with a protrusion or a card slot, and the blade 300 is fixed by the elastic force of the snap, without the need to use additional screws or tools. The replacement of the blade 300 can be completed by hand, and only a gentle press is required for disassembly or installation, significantly improving the replacement efficiency.

[0056] It is understandable that, with reference to Figure 2 As shown, the blade 300 is provided with a first connection hole (not marked in the figure), and the mounting groove 141 is provided with a second connection hole 130. An external fixing member sequentially passes through the first connection hole and the second connection hole 130 to fixedly connect the blade 300 to the tool mounting seat 100, reducing the probability of separation between the blade 300 and the tool mounting seat 100 during the chamfering process and improving the safety and stability of the chamfering tool machining.

[0057] The chamfering device according to the second aspect embodiment of the present application includes the chamfering tool according to the first aspect embodiment of the present application, and can perform chamfering on the water delivery holes of a multi-cavity number template with blind holes and improve the machining efficiency.

[0058] The chamfering method according to the third aspect embodiment of the present application, as Figure 6 shown, uses the chamfering tool according to the first aspect embodiment of the present application, and includes steps S100 to step S800:

[0059] Step S100, inserting the connecting rod 400 into the water delivery hole of the template to the chamfering position of the template; wherein, the chamfering position includes a first water delivery hole and a second water delivery hole that are opposite in position;

[0060] Step S200, placing the chamfering tool into the chamfering position;

[0061] Step S300, inserting the connecting rod 400 into the connecting channel 110;

[0062] Step S400, passing the fixing component 200 through the fixing channel 120 and embedding it into the positioning groove;

[0063] Step S500, starting the electric drill to rotate the chamfering tool;

[0064] Step S600: Push the chamfering tool forward and make it abut against the first water delivery hole, so as to form a first chamfer at the end of the first water delivery hole close to the second water delivery hole.

[0065] Step S700: Change the rotation direction of the driving end of the electric drill to change the rotation direction of the chamfering tool.

[0066] Step S800: Pull the chamfering tool backward and make it abut against the second water delivery hole, so as to form a second chamfer at the end of the second water delivery hole close to the first water delivery hole.

[0067] Through the cooperation of the connecting rod 400, the chamfering tool and the fixing component 200 in the above embodiment, the two-way chamfering processing of the relatively arranged first water delivery hole and the second water delivery hole in the blind hole template is realized, without disassembling or readjusting the tool, thus improving the processing efficiency. By inserting the connecting rod 400 into the water delivery hole to the chamfering processing position, the accurate positioning of the tool is ensured; by using the fixing component 200 to be embedded in the positioning groove, the stability and reliability of the tool mounting seat 100 during the processing are guaranteed, and the deviation is prevented. The chamfering tool is first pushed forward under the drive of the electric drill to form a chamfer of the first water delivery hole, and then by changing the rotation direction of the electric drill, the tool rotates in the reverse direction and is pulled backward to realize the chamfering processing of the second water delivery hole. This method can complete the front and rear two-way chamfering in a single clamping, avoiding the problems of step-by-step processing, repeated positioning or tool replacement in the traditional method, greatly improving the processing accuracy and consistency, reducing the human error, and improving the production efficiency at the same time.

[0068] The above has described the embodiments of the present application in detail with reference to the drawings, but the present application is not limited to the above embodiments.
