[0023] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings.
[0024] like Figure 1-4 As shown, the electric machining tool for tapered threads of this utility model includes a base, a power assembly, a transmission assembly, a tool assembly, a sliding assembly, a clamping assembly, and a feed assembly. Specifically, the power assembly includes a motor 3, and the transmission assembly includes a reducer 2 and a shaft connector 4. The motor 3 is fixed to one end of the base 1, the reducer 2 is located in front of the motor 3, and the shaft connector 4 is located at the output end of the reducer 2. The motor 3 and the reducer 2 are enclosed by a motor cover 17, which is rectangular in shape. An operation panel is provided on the motor cover 17, and the operation panel is electrically connected to the motor 3 and the reducer 2 for controlling the start and stop of the power assembly and the transmission assembly, as well as setting corresponding parameters.
[0025] The tool assembly includes a tool holder 5, a tool collet 6, and a tool holder nut 8. The tool holder 5 is bolted to the shaft connector 4. The tool collet 6 is disposed inside the tool holder 5. The tool holder nut 8 is threaded onto the tool holder 5, securing the tool collet 6. The tool collet 6 is tapered, with its tapered outer wall contacting the tapered inner hole of the tool holder 5. When the tool holder nut 8 is tightened onto the tool holder 5, it axially pushes the tool collet 6 towards the tool holder 5. Under the action of the tapered inner hole, the tool collet 6 gradually tightens, thereby clamping the tool. (See attached diagram) Figure 4 The document shows the cutting tool used for thread machining. The die 10 is set in the die holder 9, one end of which is inserted into the inner hole of the tool collet 6. Tightening the tool holder nut 8 clamps the die holder 9.
[0026] The sliding assembly includes a slider 24 and a slide rail 25. Two sets of slide rails 25 are arranged side-by-side and fixed to the slide groove 28 of the base 1 by screws. The slider 24 is mounted on the slide rail 25. The slide groove 28 is coaxial with the shaft connector 4, therefore, the slider 24 can slide axially in the tool assembly. The feed assembly is located between the two sets of slide rails 25. The feed assembly includes a lead screw nut 22 and a lead screw 27. The lead screw nut 22 is connected to the slider 24, and the lead screw 27 is threaded onto the lead screw nut 22 and parallel to the slide rail 25. In a preferred embodiment, the lead screw nut 22 is connected to a lead screw nut connector 23 located behind it. The lead screw nut connector 23 and the sliders 24 on both sides are connected by screws to a material clamping moving plate 21 located above it. When the lead screw 27 feeds, the lead screw nut 22 drives the slider 24 to move axially together. The lead screw 27 is further provided with a front bearing seat 20 and a rear bearing seat 26 at both ends. The front bearing seat 20 and the rear bearing seat 26 are fixed to the base 1 by screws. Bearings 19 are installed inside the front bearing seat 20 and the rear bearing seat 26, and the bearings 19 are ringed around both ends of the lead screw 27. The front bearing seat 20 and the rear bearing seat 26 provide support for the feed of the lead screw 27, and the bearings 19 facilitate the rotation of the lead screw 27. Furthermore, a handwheel 18 is also provided on the lead screw 27, see Appendix. Figure 1The handwheel 18 is threaded to the front end of the lead screw 27. The handwheel 18 facilitates the rotation of the lead screw 27, thereby controlling the relative position of the slider 24.
[0027] The clamping assembly includes a steel pipe clamp 11 and a clamping base 14. The clamping base 14 has a square bottom and a cylindrical top, with a support portion between the bottom and the top. The steel pipe clamp 11 is generally cylindrical with a tapered enlargement at one end, and is positioned within the cylindrical top of the clamping base 14. The steel pipe clamp 11 is used to clamp the steel pipe 15 to be processed. The bottom of the clamping base 14 is fixed to the clamping moving plate 21 by screws, allowing the clamped steel pipe 15 to move towards or away from the tool assembly along with the slider 24. Furthermore, a steel pipe clamp seat 13 is provided between the steel pipe clamp 11 and the clamping base 14, and the steel pipe clamp seat 13 has a flared opening that mates with the tapered enlargement of the steel pipe clamp 11. The front end of the steel pipe clamp 11 is threaded with a locking nut 16. The end face of the locking nut 16 is in close contact with the end face of the upper cylindrical part of the clamp fixing seat 14. See Appendix. Figure 3 During tightening, the locking nut 16 applies an axial tension to the steel pipe clamp 11, forcing the tapered enlarged part of the steel pipe clamp 11 to press against the flared opening of the steel pipe clamp seat 13, thereby clamping the steel pipe 15.
[0028] The base 1 also has a toolbox 12, see attached. Figure 1 and 2 The toolbox 12 is square, and inside it are arranged different sizes of chamfering cutters 7, dies 10 (including die holders 9), and pipe clamps 11. The chamfering cutter 7 is used for machining conical surfaces, and the die 10 is used for machining nuts. The chamfering cutter 7 is installed in the same way as the die 10. When machining steel pipes of different specifications, only the appropriate pipe clamp 11 and cutting tools need to be replaced, greatly improving its applicability.
[0029] The working principle of this utility model is as follows: When using the equipment, connect it to the power supply and ensure that all components are functioning normally. Select the corresponding program through the operation panel of the motor cover 17 according to the diameter of the steel pipe 15 to be processed. Turn the handwheel 18 to move the material clamping seat 14 away from the tool assembly via the slider 24. Insert one end of the steel pipe 15 into the steel pipe collet 11, ensuring that the steel pipe 15 extends to a sufficient processing length. Tighten the locking nut 16 to clamp the steel pipe 15. Select a chamfering cutter 7 of the appropriate specifications from the tools 12, insert one end of the chamfering cutter 7 into the tool collet 6, and tighten the tool handle nut 8 to clamp the chamfering cutter 7. Press the start button of the motor 3. The motor 3 converts electrical energy into mechanical energy, outputting high-speed rotational power. The power output by the motor 3 reduces the speed and increases the torque through the reducer 2, driving the chamfering cutter 7 to rotate rapidly. Turn the handwheel 18 evenly to move the material clamping seat 14 at a uniform speed towards the chamfering cutter 7, beginning the processing of the conical surface. During processing, observe the processing status and stop the equipment immediately for adjustment if any abnormalities are found. After the conical surface processing is completed, turn off the motor 3, and crank the handwheel 18 in the reverse direction to make the slider 24 drive the material clamp fixing seat 14 back to the initial position. Loosen the tool holder nut 8, remove the chamfering tool 7, select the appropriate die 10 from the tool box 12, and call the corresponding program on the operation panel to perform thread processing.
[0030] Before thread machining, push the end of the steel pipe 15 with the handwheel 18 to the position where it engages with the die 10. Then, press the corresponding machining button on the control panel. The die 10 engages with the steel pipe 15, causing the steel pipe 15 to move inward along the slide rail to achieve thread machining. After thread machining is completed, turn off the motor 3, and reverse the handwheel 18 to make the slider 24 move the material clamp fixing seat 14 back to its initial position. Loosen the locking nut 16, remove the machined steel pipe 15, remove the die 10 and put it back in the tool box 12, and turn off the power.
[0031] The feeding method of this invention is not limited to manual feeding; for example, automatic feeding can be achieved by controlling the slider 24 via circuitry. The cutting tool is made of a special cemented carbide material, which has high hardness, high wear resistance, and good heat resistance. The tool tip shape has been optimized to ensure cutting smoothness and accuracy when machining conical surfaces; and to precisely control the pitch and thread depth when machining threads.
[0032] The basic principles and advantages of this utility model have been described above. For those skilled in the art, the above embodiments are merely illustrative of the technical solutions of this utility model and not intended to limit it. Although this 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 or all of the technical features by reading this specification. Any obvious substitutions are within the protection scope of this utility model without departing from its concept.
