[0002] The motor connecting shaft refers to the dedicated shaft segment and its connecting components at the output end of the motor used to transmit rotational power and realize mechanical energy transmission. It must meet the three core functions of torque transmission, centering maintenance, and displacement compensation to ensure efficient and reliable linkage between the motor and the load equipment. The motor connecting shaft is usually connected by components such as keyways, flange bolts, and couplings. Installing these connecting components requires boring holes on the connecting shaft to facilitate connection.

[0003] Existing tapered hole boring tools are generally of one-piece structure, which is too costly to replace after damage. The boring angle of the tool is not adjustable, and the style and size of the motor connecting shaft are also different, requiring different boring depths. In order to address this technical problem, this application proposes a boring tool for motor connecting shaft. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-2 This utility model provides an embodiment of a boring tool for a motor connecting shaft, comprising a tool head 1, on which an alloy insert 5 is mounted for boring. A tool body 2 is connected to the bottom outer wall of the tool head 1 via a telescopic assembly. The tool body 2 connects to the tool head 1 and adjusts the telescopic distance of the tool head 1, thereby controlling the boring depth. A fixing groove 9 is formed on the bottom outer wall of the tool body 2, which is used to fix the tool body 2 to the inner wall of a tool holder 3. A sliding rod 16 is slidably connected to the inner wall of the tool body 2, which is used to push the telescopic assembly. A tool holder 3 is provided on the outer wall of the tool body 2. A retaining ring 4 is fixedly connected to the bottom of the tool holder 3. The boring tool can be installed on the lathe through the retaining ring 4 at the bottom of the tool holder 3. A push rod 8 is slidably connected to the inner wall of the bottom of the retaining ring 4. The push rod 8 is used to drive the fixing component. An oil storage area 14 is opened in the middle inner wall of the retaining ring 4. The oil storage area 14 is used to store hydraulic oil. The end of the push rod 8 is connected to the fixing groove 9 through the fixing component. The fixing groove 9 can be fixed by driving the fixing component through the push rod 8. A connecting rod 7 is slidably connected to the inner wall of the push rod 8. The end of the connecting rod 7 is connected to the slide rod 16. The slide rod 16 can be driven through the connecting rod 7.

[0024] Reference Figures 2-4 The telescopic assembly includes a limiting block 17 fixedly connected to the outer wall of the bottom of the cutter head 1. The outer wall of the limiting block 17 is slidably connected to the inner wall of the cutter body 2. The bottom side of the cutter head 1 is fixedly connected to the slide rod 16. A second spring 18 is sleeved on the outer wall of the cutter head 1. One end of the second spring 18 is connected to the cutter body 2, and the other end of the second spring 18 is connected to the limiting block 17. The cutter head 1 is pushed by the connecting rod 7 through the slide rod 16, which will then push the cutter head 1 out of the inner wall of the cutter body 2, thereby extending it. When the connecting rod 7 retracts backward, the second spring 18 pushes the limiting block 17, thereby causing the cutter head 1 to retract.

[0025] The fixing assembly includes a piston 15 fixedly connected to the end of the push rod 8. The outer wall of the piston 15 is slidably connected to the oil storage area 14. Oil pipes 13 are provided on both sides of the oil storage area 14. An annular oil cavity 12 is provided at the end of the oil pipe 13. Two fixing blocks 10 are slidably connected to the inner wall of the annular oil cavity 12. The outer wall of the two fixing blocks 10 on the side closest to each other is connected to the fixing groove 9. The annular oil cavity 12 is opened on the inner wall of the top side of the tool holder 3. A spring 11 is sleeved on the outer wall of the side opposite to each other of the two fixing blocks 10. One end of the spring 11 is connected to the tool holder 3, and the other end of the spring 11 is connected to the fixing groove 9. Block 10 is connected, and the piston 15 is moved by the push rod 8, thereby squeezing the hydraulic oil in the oil storage area 14 into the annular oil chamber 12 through the oil pipe 13. Then, the fixing block 10 in the annular oil chamber 12 is squeezed out, thereby clamping it in the fixing groove 9 on the bottom outer wall of the blade 2 to prevent it from vibrating. When it needs to be replaced, the connecting rod 7 is released, and the spring 11 pushes the fixing block 10, so that the hydraulic oil returns from the annular oil chamber 12 to the oil storage area 14 through the oil pipe 13, thereby making the fixing block 10 return to the inner wall of the blade holder 3, thereby releasing the blade 2, which makes it easy to replace.

[0026] The top of the cutter head 1 has a mounting groove 6, through which the blade 5 can be installed. The blade 5 is installed on the outer wall of the mounting groove 6 by screws. The blade 5 is mainly made of alloy material and is used for boring the motor connecting shaft.

[0027] Working principle: When boring is required, the tool is fixed to the lathe by the retaining ring 4 at the bottom of the tool holder 3. Then, the tool body 2 is installed into the inner wall of the tool holder 3. The lathe presses the push rod 8, which pushes the piston 15 to move, thereby squeezing the hydraulic oil in the oil reservoir 14 into the annular oil chamber 12 through the oil pipe 13. Then, the fixing block 10 in the annular oil chamber 12 is squeezed out, thus clamping it in the fixing groove 9 on the bottom outer wall of the tool body 2 to prevent it from vibrating during rotation, thereby fixing the tool body 2. After calibration, the lathe will rotate the tool holder 3 to drive the cutting tool 5 at the top of the tool head 1 to rotate, and then the boring operation will begin. When a deeper hole needs to be bored, the lathe pushes the connecting rod 7, which pushes the cutting head 1 out of the inner wall of the tool body 2, thus extending the cutting head 1. When a shallower hole needs to be bored, the connecting rod 7 retracts, and then the spring 18 pushes the limiting block 17, which in turn retracts the cutting head 1, reducing the extension distance of the cutting head 1. When the boring tool is worn and needs to be replaced, the connecting rod 7 is released, and the spring 11 pushes the fixing block 10, allowing the hydraulic oil to return from the annular oil chamber 12 along the oil pipe 13 back to the oil storage area 14, thus allowing the fixing block 10 to return to the inner wall of the tool holder 3, thereby releasing the tool body 2 for easy replacement.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
