Therefore, they should not be construed as limitations on this utility model.

[0019] Examples of embodiments of this utility model Figures 1 to 3As shown, a tapping machine for preventing tap breakage includes a base 1. An operating table is mounted on the top of the base 1, and a lifting mechanism is mounted on the operating table. A control box 4 is mounted on the lifting mechanism, and a control switch is mounted on the left side wall of the control box 4. A connecting shaft 5 is mounted at the bottom of the control box 4, and a connecting rod 50 is connected to the connecting shaft 5. The connecting rod 50 is connected to the lifting mechanism and moves up and down with the connecting shaft 5. A protective shell 6 is mounted at the bottom of the connecting shaft 5. The protective shell 6 is a hollow frustum-shaped cone structure, with both its upper and lower surfaces open. The upper surface of the protective shell 6 is connected to the bottom surface of the connecting shaft 5. A torque protector 60 is mounted at the bottom of the connecting shaft 5, located inside the protective shell 6. A mounting spindle 61 is mounted at the bottom of the torque protector 60. A tapping head 7 is mounted at the bottom of the mounting spindle 61, which engages with the tap for tapping. The tapping head 7 clamps the tap and rotates it for tapping. The side of the tapping head 7... A tapping head stabilizing rod 70 connected to the protective housing 6 is provided on the wall. A ring-shaped laser ring lamp 71 is provided at the bottom of the tapping head 7. The laser ring lamp 71 is coaxial with the tap. A motor 8 for driving the tapping head 7 to perform tapping is provided on the control box 4. Preferably, the connecting shaft 5 is provided at the bottom of the control box 4 through the motor. At this time, the motor 8 is located at the bottom of the control box 4 near the front. A mounting ring is provided at the bottom of the motor 8. The output shaft of the motor 8 is coaxial with the mounting ring. The top of the outer wall of the connecting shaft 5 is connected to the inner ring of the mounting ring. The output shaft of the motor 8 passes through the connecting shaft 5, the torque protector 60 and the mounting spindle 61 and is connected to the input end of the tapping head 7. Preferably, the tapping head 7 holds a calibration shaft. After calibration by the laser ring lamp 71 and the calibration shaft, the tapping head 7 releases the calibration shaft and holds the tap to perform tapping. The laser ring lamp 71, the motor 8, the lifting mechanism, the torque protector 60 and the tapping head 7 are all electrically connected to the control box.

[0020] By aligning the center of the laser ring emitted by the laser ring lamp 71 with the drilling position to be tapped, the tapping position can be quickly determined, allowing the tap to be aligned with the required drilling hole. The vibration generated by the tap during tapping is distributed to the protective housing 6 through the tapping head stabilizing rod 70, and also distributed to the lifting mechanism through the connecting shaft 5. The lifting mechanism and the protective housing 6 together share the vibration generated by the tap, making the tapping process more stable and preventing excessive tap vibration that could lead to tap breakage. Finally, the torque protector 60 monitors the load change of the tap in real time. When the force of the tap rotation is overloaded, the control box 4 automatically stops the motor 8 to prevent the tap from breaking due to excessive resistance.

[0021] Further improvements, such as Figure 1 and Figure 2As shown, a spindle stabilizer 62 connected to the protective housing 6 is provided on the side wall of the mounting spindle 61. Multiple spindle stabilizers 62 are provided and are arranged at equal intervals along the circumference of the side wall of the mounting spindle 61. The spindle stabilizers 62 further enhance the ability to distribute the vibration of the tapping head 7, thereby reducing the vibration of the tap on the tapping head 7. The multiple equally spaced spindle stabilizers 62 make the vibration distribution more uniform.

[0022] Further improvements, such as Figure 1 and Figure 2 As shown, the operating table includes a connecting platform 2, the bottom end of which is connected to the base 1. A groove 20 is provided on the top surface of the connecting platform 2. A buffer pad 21 is provided in the groove 20, covering the bottom of the groove 20. A worktable 22 is provided on the buffer pad 21. The lifting mechanism is provided on the worktable 22. The groove 20 collects the waste chips and coolant generated during tapping, preventing the waste chips and coolant from falling to the ground and being difficult to clean. The buffer pad 21 buffers the vibration generated during operation, avoiding excessive vibration that could cause the tap to become unstable.

[0023] Further improvements, such as Figure 1 and Figure 3 As shown, the lifting mechanism includes a mounting base 3, which is located at the top of the operating table. The mounting base 3 is positioned on the top surface of the worktable 22. A hydraulic rod 30 extending vertically is mounted on the mounting base 3. A connecting sleeve 31 is fixedly fitted onto the output shaft of the hydraulic rod 30. The connecting rod 50 is connected to the connecting sleeve 31. The control box 4 is located at the top of the output shaft of the hydraulic rod 30. The hydraulic rod 30 and the connecting shaft 5 are connected as one unit through the connecting rod 50 and the connecting sleeve 31, thereby sharing the vibration generated during lifting and tapping, thus reducing the vibration amplitude and improving the stability of the tapping machine during operation.

[0024] Further improvements, such as Figure 2 and Figure 3 As shown, multiple tap head stabilizing rods 70 are provided, and the multiple tap head stabilizing rods 70 are arranged at equal intervals along the circumference of the side wall of the tap head 7. The multiple tap head stabilizing rods 70 make the vibration of the tap head 7 more evenly distributed.

[0025] Further improvements, such as Figure 1 and Figure 3 As shown, the base 1 has a cavity 10 inside, and a power supply 11 electrically connected to the control box 4 is provided inside the cavity 10. The outer wall of the base 1 has an electrical cabinet door 12 for switching the cavity 10, which facilitates the maintenance of the power supply 11 or the wiring of the power supply 11.

[0026] Further improvements, such as Figure 1 and Figure 3 As shown, stabilizing blocks 9 are provided on both opposite side walls of the base 1. The bottom surface of the stabilizing block 9 is coplanar with the bottom surface of the base 1. The base 1 and the stabilizing block 9 are integrally formed. The stabilizing block 9 increases the contact area between the base 1 and the ground, and also increases the weight of the base 1, thereby increasing the stability of the tapping machine.
