Description

Technical Field

[0001] This invention relates to the field of terminal tapping technology, specifically to a tapping device based on terminal processing. Background Technology

[0002] Terminal blocks are core basic components for electrical equipment wiring connections. They are mainly used to achieve neat connection and conductive fixation of cables. To meet the requirements of cable assembly and locking, the connection holes of the terminal blocks need to be pre-machined with standard internal threads. The tapping device based on terminal block machining uses a lifting and rotating drive structure to drive the tapping tool to rotate and move downward, completing the automated tapping operation of the terminal block holes. It can replace the traditional manual tapping and simple machine tool processing mode, effectively improving the efficiency and consistency of terminal block thread processing.

[0003] Current terminal block tapping devices suffer from structural wear and increased clearance under long-term continuous processing conditions. The lifting and guiding structure of the equipment is prone to excessive clearance due to long-term reciprocating sliding. The support bearings of the rotating components are prone to wear and loosening. At the same time, the tapping rod is prone to slight bending deformation under continuous high-speed rotation and reciprocating cutting force. This causes the tapping tool to circumferentially wobble and vibrate irregularly throughout the lifting and processing process, which is not easy to detect in time. As a result, the terminal block thread processing has uneven texture, thread diameter deviation, and tooth profile damage.

[0004] To address the above issues, a tapping device based on terminal block machining is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a tapping device based on terminal block processing.

An arc-shaped positioning plate is fixedly connected to the bottom of each of the several arc-shaped pressure blocks. A first spring is fixedly connected to one side of each of the several first pistons. One end of the first spring is fixedly connected to the inner wall of the ring.

[0011] Furthermore, the hydraulic transmission assembly includes several first connecting pipes connected to one side of the ring, a circular branch pipe fixedly connected to the outer ring, several first connecting pipes connected to the circular branch pipe, a second connecting pipe connected to one side of the circular branch pipe, a fixed frame fixedly connected to one side of the bearing seat, a first connecting cavity and a second connecting cavity respectively opened in the fixed frame, the second connecting pipe connected to the first connecting cavity, a first connecting pipe and a second connecting pipe respectively arranged in the fixed frame, and a one-way valve and a solenoid valve respectively installed on the first connecting pipe and the second connecting pipe.

[0014] Furthermore, a tapping detection component for detecting the wear of the tapping component is slidably installed inside the circumferential detection component. The tapping detection component includes two L-shaped lifting rods slidably connected inside the bearing seat. One end of each L-shaped lifting rod is fixedly connected to a circular plate.

The abnormality can be identified in the early stage of the yaw failure, avoiding the problem of batch workpiece defects caused by manual post-inspection. Through the cooperation between the pressure detection component, the drive component, and the hydraulic transmission component, when the tapping component deflects beyond the safety threshold, the hydraulically driven circumferential detection component can be used to clamp and pull inward, thereby applying emergency braking to the rotating tapping rod to prevent the tool from swinging at high speed and impacting the workpiece and equipment, thus improving the safety performance of equipment operation. By cooperating with the reset component and the circumferential detection component, coaxial reference calibration can be performed on multiple sets of arc-shaped pressure blocks after equipment maintenance, so that the pressure detection component returns to the initial reference value, eliminates the zero-point drift of detection caused by component wear, and ensures the reliability of subsequent sway detection results. By cooperating with the tapping detection component, the push component, and the pressure detection component, the tapping head wear can be automatically detected periodically. The tool wear and chipping status can be identified and warned through the same pressure sensing path, eliminating the need for manual visual inspection and prompting tool replacement in advance, thus reducing the production of defective products. By setting up the hydraulic transmission component, a single hydraulic path can be used to perform multiple functions, including yaw signal transmission, emergency braking hydraulic output, and wear detection force transmission. The pressure detection component can be reused to complete two types of fault monitoring, reducing the number of sensors and simplifying the overall hardware structure and control logic.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1 As shown, the tapping device based on terminal block processing includes a workbench 1, which can support and fix various components. A controller 11 is fixedly installed on the top of the workbench 1, and the controller 11 is used to control various electrical components.

[0021] To address the technical problem of circumferential runout and irregular vibration of tapping tools during prolonged tapping, which are difficult to detect in a timely manner, the following preferred technical solution is provided: like Figures 1-8As shown, a loading limit component 2 is provided on the top of the workbench 1. The loading limit component 2 is used to constrain the posture and step convey the terminal block to be processed. A lifting component 3 is provided on the top of the workbench 1. A rotating component 4 is provided on one side of the lifting component 3. A tapping component 5 is provided on one side of the rotating component 4. An arrival monitoring component 6 is provided on one side of the lifting component 3. A circumferential detection component 7 is provided on one side of the lifting component 3 to detect the circumferential sway of the tapping component 5. A hydraulic transmission component 8 is connected to one side of the circumferential detection component 7. A pressure detection component 9 is provided inside the hydraulic transmission component 8. A drive component 10 is provided inside the hydraulic transmission component 8. The drive component 10 is connected to the pressure detection component 9. A reset component 20 for calibration and reset is provided at the bottom of the circumferential detection component 7. In use, the terminal blocks to be tapped are placed in the loading limit assembly 2, and the controller 11 causes the pushing structure in the loading limit assembly 2 to move the terminal blocks to the tapping position. At this time, the hole positions of the terminal blocks to be tapped correspond to the axial center position of the tapping structure in the tapping assembly 5. During the pushing and loading process, the position monitoring assembly 6 can confirm whether the hole positions of the terminal blocks have accurately reached the tapping position. Then, the controller 11 causes the rotating assembly 4 to drive the tapping assembly 5 to rotate, and then the lifting assembly 3 drives the rotation of the tapping assembly 5. Component 4 and tapping component 5 move down synchronously, causing the tapping structure inside tapping component 5 to tap the terminal block. After tapping is completed, rotating component 4 drives tapping component 5 to rotate in the opposite direction. At the same time, lifting component 3 drives rotating component 4 and tapping component 5 to move up and reset synchronously, completing the entire tapping operation. Then, controller 11 causes the pushing structure inside loading limit component 2 to push the terminal block to the next tapping station and perform tapping operation again. This cycle repeats. Through the above operation, continuous automated tapping of the terminal block can be achieved. When the guide clearance of the lifting component 3 increases, the bearing of the rotating component 4 wears and loosens, and the tapping component 5 itself is bent and deformed and wobbles, the tapping component 5 will experience circumferential wobble vibration during the tapping process. At this time, the tapping structure inside the tapping component 5 that causes wobble will push the circumferential detection structure inside the circumferential detection component 7 to translate, so that the hydraulic oil inside the circumferential detection component 7 pushes the pressure detection component 9 through the hydraulic transmission component 8, causing the pressure value detected by the pressure detection component 9 to rise abnormally and fluctuate. Case 1: If the value of the pressure detection component 9 is between the preset warning threshold and the safety threshold, the lifting component 3 and the rotating component 4 will be stopped by the controller 11, and the alarm will be triggered to remind the user to perform maintenance. The controller 11 is existing technology and is not shown in the figure. The above operation can stop the machine and alarm in time when abnormal runout occurs during tapping. Compared with the existing technology that relies on manual inspection after the fact, it can trigger protection in the early stage of runout and avoid the generation of batch defective products. Case 2: If the value of the pressure detection component 9 continues to rise and exceeds the preset safety threshold, the controller 11 will stop the lifting component 3 and the rotating component 4. When the rotation speed of the rotating component 4 drops to the preset safe low speed, the controller 11 will open the valve structure in the hydraulic transmission component 8. Then, the drive component 10 will drive the pressure detection component 9 to move, pushing the hydraulic oil in the hydraulic transmission component 8 into the circumferential detection component 7. This will cause the circumferential detection structure in the circumferential detection component 7 to converge and clamp the braking tapping component 5. The above operation can be used to perform emergency clamping and braking on the tapping assembly 5 when the runout is severely exceeded. Compared with the existing technology, which only stops the machine and allows the tapping assembly 5 to swing freely, it can prevent the tapping assembly 5 from swinging at high speed and hitting the workpiece or equipment, thus improving the safety of the equipment. During the tapping operation, the lifting component 3 drives the rotating component 4 and the tapping component 5 to move up and down repeatedly. Therefore, when the circumferential detection component 7 performs full-range follow-up sway detection, it can capture the instantaneous sway displacement of the tapping component 5 in the lifting stroke within a certain height range in real time, thereby improving the comprehensiveness and accuracy of the equipment in detecting tapping offset faults. After situation 1 occurs and maintenance is performed, the valve structure in the hydraulic transmission component 8 is opened by the controller 11. Then, the user pushes the reference reset component 20 upward and pulls several circumferential detection components 7 closer to each other and into contact with the reference reset component 20. At this time, the value of the pressure detection component 9 is at the initial reference value. During the process, the hydraulic oil in the hydraulic transmission component 8 flows back to several circumferential detection components 7, which can restore the circumferential detection components 7 to the initial detection reference state.

[0022] like Figure 2 and Figure 3 As shown, the feeding limit assembly 2 includes a feeding frame 21 fixedly connected to the top of the workbench 1. A hydraulic cylinder 22 is fixedly installed on the top of the workbench 1. A T-shaped slide plate 23 is fixedly connected to the movable end of the hydraulic cylinder 22. The T-shaped slide plate 23 is slidably connected to the feeding frame 21. A feeding groove 24 is opened on the top of the feeding frame 21. An inclined feeding frame 25 is provided on one side of the feeding frame 21. A sliding groove is opened inside the feeding frame 21. The T-shaped slide plate 23 and the terminal block that needs to be tapped are slidably connected to the inner wall of the feeding frame 21, which can limit and guide the terminal block and push it accurately station by station. The lifting assembly 3 includes a support frame 31 fixedly connected to the top of the workbench 1. An electric push rod 32 is installed on the top of the support frame 31. The movable end of the electric push rod 32 is fixedly connected to a lifting seat 33. The lifting seat 33 is slidably connected to the support frame 31. like Figures 2-4As shown, the rotating assembly 4 includes a lifting frame 41 fixedly connected to the lifting base 33. A servo motor 42 is installed on one side of the lifting frame 41. A rotating shaft 43 is fixedly connected to the movable end of the servo motor 42. The rotating shaft 43 is rotatably connected to the lifting frame 41. The servo motor 42 is a servo motor 42 with a speed encoder, which can perform forward and reverse rotation and can detect the speed of the rotating shaft 43.

[0023] like Figure 4 and Figure 5 As shown, the tapping assembly 5 includes a coupling 51 fixedly connected to one end of the rotating shaft 43. A tapping rod 52 is fixedly connected to one end of the coupling 51, and a tapping head 53 is fixedly connected to one end of the tapping rod 52. The tapping rod 52 and the tapping head 53 form a tapping tool assembly, which can perform internal thread processing on the pre-made holes of the terminal block.

[0024] like Figure 3 As shown, the positioning monitoring component 6 includes a mounting base 61 fixedly connected to one side of the lifting seat 33. A vision sensor 62 is installed on one side of the mounting base 61. The vision sensor 62 is tilted towards the terminal block hole, which can identify the hole position and determine whether the material is in place.

[0025] like Figures 4-8 As shown, the circumferential detection assembly 7 includes a bearing seat 71 fixedly connected to one side of the support frame 31. A ring 72 is fixedly connected inside the bearing seat 71. Several first pistons 73 are evenly slidably connected inside the ring 72. A sliding rod 74 is fixedly connected to one side of each of the first pistons 73. An arc-shaped pressure block 75 is fixedly connected to one end of each sliding rod 74. A wear-resistant layer 76 is fixedly connected to one side of each of the arc-shaped pressure blocks 75. The arc-shaped pressure blocks 75 form a ring-shaped circumferential detection array, which can simultaneously detect the circumferential movement of the tapping rod 52 from multiple directions. The yaw displacement is achieved by several arc-shaped pressure blocks 75 being coaxially arranged with the tapping rod 52, while maintaining a small detection gap with the tapping rod 52. This avoids contact and friction between the arc-shaped pressure blocks 75 and the tapping rod 52 during normal tapping, ensuring detection accuracy. There is a movable gap between the arc-shaped pressure blocks 75, which facilitates subsequent clamping operations. Each of the arc-shaped pressure blocks 75 has an arc-shaped positioning plate 77 fixedly connected to its bottom. Each of the first pistons 73 has a first spring 78 fixedly connected to one side, with one end of the first spring 78 fixedly connected to the inner wall of the ring 72.

[0026] like Figure 5 , Figure 6 and Figure 8As shown, the hydraulic transmission assembly 8 includes several first connecting pipes 81 connected to one side of the ring 72. A circular branch pipe 82 is fixedly connected to the outer ring of the ring 72. The several first connecting pipes 81 are all connected to the circular branch pipe 82. A second connecting pipe 83 is connected to one side of the circular branch pipe 82. A fixed frame 84 is fixedly connected to one side of the bearing seat 71. A first connecting cavity 85 and a second connecting cavity 86 are respectively opened in the fixed frame 84. The second connecting pipe 83 is connected to the first connecting cavity 85. A first connecting pipe 87 and a second connecting pipe 89 are respectively arranged in the fixed frame 84. A one-way valve 88 and a solenoid valve 810 are respectively installed on the first connecting pipe 87 and the second connecting pipe 89. The ring 72, the several first connecting pipes 81, the circular branch pipe 82, the second connecting pipe 83, the first connecting cavity 85 and the second connecting cavity 86 are filled with hydraulic oil, which can transmit the sway displacement of the circumferential detection assembly 7 to the pressure-bearing detection assembly 9 in the form of hydraulic pressure, and realize the bidirectional controllable flow of hydraulic oil.

[0027] like Figure 6 As shown, the pressure detection component 9 includes a second piston 91 that is slidably connected within the fixed frame 84. A second spring 92 is fixedly connected to one side of the second piston 91. A pressure sensor 93 is fixedly connected to one end of the second spring 92. A sealing plug 94 is fixedly connected to one side of the second piston 91. The sealing plug 94 fits the shape of the first connecting pipe 87. The drive assembly 10 includes two electromagnets 101 fixedly connected to the inner wall of the fixed frame 84, and two magnet blocks 102 fixedly connected to one side of the second piston 91, with the two electromagnets 101 corresponding to the two magnet blocks 102 respectively.

[0028] like Figure 7 As shown, the reference reset assembly 20 includes several guide rods 201 fixedly connected to the bottom of the ring 72. A slip ring 202 is slidably connected to the outer wall of the several guide rods 201. A third spring 203 is fixedly connected to one side of the slip ring 202. One end of the third spring 203 is fixedly connected to one side of the ring 72. A positioning ring 204 is fixedly connected to one side of the slip ring 202. The positioning ring 204 is coaxially arranged with the arc-shaped positioning plate 77.

[0029] like Figures 1-8As shown, in use, the terminal block to be tapped is placed in the loading frame 21 through the feeding groove 24. Then, the controller 11 extends the movable end of the hydraulic cylinder 22, causing the T-shaped slide plate 23 to slide within the loading frame 21, thereby pushing the terminal block to be tapped to slide under the limit of the loading frame 21 until the terminal block moves to the tapping position. At this time, the hole to be tapped on the terminal block is directly below the tapping head 53. During the pushing and feeding process, the vision sensor 62 can confirm whether the hole of the terminal block has accurately reached the tapping position. Then, the controller 11 causes the servo motor 42 to drive the rotating shaft 43, coupling 51, tapping rod 52 and tapping head 53 to rotate synchronously in the forward direction. Then, the movable end of the electric push rod 32 extends to drive the lifting and lowering. The seat 33 slides on one side of the support frame 31, causing the lifting frame 41, servo motor 42, coupling 51, tapping rod 52 and tapping head 53 to move down synchronously, so that the tapping head 53 taps the terminal block. After tapping is completed, the servo motor 42 drives the rotating shaft 43, coupling 51, tapping rod 52 and tapping head 53 to rotate in opposite directions synchronously. At the same time, the movable end of the electric push rod 32 shortens, causing the lifting seat 33 to slide on one side of the support frame 31, so that the lifting frame 41, servo motor 42, coupling 51, tapping rod 52 and tapping head 53 move up and reset synchronously, completing the entire tapping operation. Then, the controller 11 causes the movable end of the hydraulic cylinder 22 to extend, pushing the terminal block that needs to be tapped to the next tapping station, and the tapping operation is performed again. This cycle continues. Through the above operations, continuous automated tapping of terminal blocks can be achieved; When the guide clearance between the lifting seat 33 and the support frame 31 increases, the bearings of the rotating shaft 43 and the lifting frame 41 wear and loosen, and the tapping rod 52 and the tapping head 53 are bent and deformed, causing circumferential oscillation during the tapping process, the oscillating tapping rod 52 will push the wear-resistant layer 76, the arc-shaped pressure block 75 and the slide rod 74 to translate, causing the first piston 73 to slide in the ring 72 and simultaneously squeeze the first spring 78. This causes the hydraulic oil in the ring 72 to enter the first connecting cavity 85 through the first connecting pipe 81, the circular branch pipe 82 and the second connecting pipe 83. Subsequently, the hydraulic oil enters the second connecting cavity 86 through the first connecting pipe 87 and the one-way valve 88, thereby pushing the second piston 91 to slide in the fixed frame 84 and squeezing the second spring 92. This causes the pressure sensor 93 on one side of the second spring 92 to be squeezed, resulting in an abnormal increase in the detection value of the pressure sensor 93. Case 1: If the value of pressure sensor 93 is between the preset warning threshold and the safety threshold, the controller 11 will stop the electric push rod 32 and the servo motor 42, and at the same time, the alarm will sound to remind the user to perform maintenance. The alarm is existing technology and is not shown in the figure. The above operation can stop the machine and alarm in time when abnormal runout occurs during tapping. Compared with the existing technology that relies on manual inspection after the fact, it can trigger protection in the early stage of runout and avoid the generation of batch defective products. Scenario 2: If the value of pressure sensor 93 continues to rise and exceeds the preset safety threshold, the controller 11 will stop the electric push rod 32 and servo motor 42. When the speed of servo motor 42 drops to the preset safe low speed, the controller 11 will open the solenoid valve 810. This will energize the two electromagnets 101, generating magnetic force that repels the two magnet blocks 102, causing the second piston 91 to slide within the fixed frame 84. Simultaneously, the second spring 92 is stretched, and the sealing plug... 94 enters and seals the first connecting cavity 85, so that the hydraulic oil in the second connecting cavity 86 enters the first connecting cavity 85 through the second connecting pipe 89 and the solenoid valve 810, and enters the ring 72 through the second connecting pipe 83, the circular branch pipe 82 and several first connecting pipes 81, so that several first pistons 73 slide in the ring 72 and stretch the first spring 78, thereby causing several sliding rods 74, several arc-shaped pressure blocks 75 and several wear-resistant layers 76 to converge inward, thereby clamping the brake tapping rod 52; The above operation can be used to perform emergency clamping and braking on the tapping rod 52 when the runout is severely exceeded. Compared with the existing technology, which only stops the machine and allows the tapping rod 52 to swing freely, it can prevent the tapping rod 52 from swinging at high speed and hitting the workpiece or equipment, thus improving the safety of the equipment. During the tapping operation, the electric push rod 32 drives the tapping rod 52 and the tapping head 53 to move up and down repeatedly. Therefore, when performing full-range follow-up sway detection on several arc-shaped pressure blocks 75 and several wear-resistant layers 76, it can capture the instantaneous sway displacement of the tapping rod 52 in real time within a certain height range, thereby improving the comprehensiveness and accuracy of the equipment in detecting tapping deviation faults. After situation 1 occurs and maintenance is performed, the solenoid valve 810 is opened by the controller 11. Then, the user pushes the slip ring 202 to move the positioning ring 204 upward synchronously, so that the slip ring 202 slides on the outer wall of several guide rods 201 and squeezes the third spring 203, so that the positioning ring 204 and several arc-shaped positioning plates 77 are on the same horizontal plane. At this time, the user pulls several arc-shaped pressure blocks 75 respectively, so that the inner ring of several arc-shaped positioning plates 77 is in contact with the outer ring of the positioning ring 204. At this time, the first piston 73 and the second piston 91 are reset, and the values ​​of several pressure sensors 93 are at the initial reference value. During the process, the hydraulic oil in the second connecting cavity 86 flows back into the ring 72, which can complete the reference calibration reset of the circumferential detection component 7.

[0030] To address the technical challenge of easily detecting wear on tapping tools, the following preferred technical solutions are provided: like Figures 3-6 As shown, a tapping detection component 30 for detecting the wear of the tapping component 5 is slidably disposed inside the circumferential detection component 7, and a pushing component 40 for transmitting the detection thrust is slidably disposed inside the hydraulic transmission component 8, and the pushing component 40 is connected to the pressure-bearing detection component 9; During prolonged tapping operations, the tapping structure within the tapping assembly 5 is prone to wear. In this case, the controller 11 performs a wear detection operation on the tapping assembly 5 at regular intervals. During this operation, the controller 11 causes the lifting assembly 3 to drive the rotating assembly 4 and the tapping assembly 5 to move upwards synchronously. Simultaneously, the rotating assembly 4 drives the tapping assembly 5 to rotate slowly, causing the tapping assembly 5 to screw into the tapping detection assembly 30. Then, the driving of the rotating assembly 4 is stopped, allowing the tapping assembly 5 and the tapping detection assembly 30 to form a threaded engagement. Afterwards, the controller 11 causes the lifting assembly 3 to drive the rotating assembly 4, the tapping assembly 5, and the tapping detection assembly 30 to move upwards a short distance synchronously, causing the tapping detection assembly 30 to push the component... 40 slides within the hydraulic transmission component 8, causing the pressure detection component 9 to move a short distance. At this time, the pressure detection value of the pressure detection component 9 remains at a preset reference value. Subsequently, through the controller 11, the rotating component 4 drives the tapping component 5 to rotate slowly. During the rotation, through the threaded engagement between the tapping component 5 and the tapping detection component 30, the tapping detection component 30 moves slowly downward. If the detection value of the pressure detection component 9 continues to decrease steadily and the fluctuation is within the preset normal wear range, it is determined that the tapping component 5 is worn normally and can continue to be used. If the pressure value of the pressure detection component 9 decreases and the fluctuation exceeds the preset abnormal range, it is determined that the tapping component 5 is abnormally worn or has chipped and needs to be replaced. At this time, an alarm is triggered to remind the user to carry out maintenance. The above operation can be used to periodically and automatically detect the wear condition of the tapping component 5. Compared with the existing technology that relies on manual visual inspection, it can judge the degree of wear and give early warning for replacement, thus avoiding the production of defective products. If the tapping structure inside the tapping assembly 5 has been inspected and the wear is determined to be normal, the tapping assembly 5 will be slowly rotated in the opposite direction to reset by rotating the assembly 4.

[0031] like Figures 4-6As shown, the tapping detection assembly 30 includes two L-shaped lifting rods 301 slidably connected within the bearing seat 71. One end of each L-shaped lifting rod 301 is fixedly connected to a circular plate 302. The circular plate 302 has a threaded groove 303. The circular plate 302 is made of wear-resistant alloy material and can withstand multiple tapping head 53 insertion tests without significant wear. At the same time, the detection cycle can adapt to the tapping head 53 cycle, reducing misjudgments caused by wear of the circular plate 302 itself. The threaded groove 303 fits with the tapping rod 52. Limiting plates 304 are fixedly connected to both sides of the L-shaped lifting rods 301. The limiting plates 304 are slidably connected to the inner wall of the bearing seat 71. A fourth spring 305 is fixedly connected to one side of the limiting plate 304. One end of the fourth spring 305 is fixedly connected to the inner wall of the bearing seat 71. One end of one L-shaped lifting rod 301 is rotatably connected to a roller 306.

[0032] like Figure 6 As shown, a guide post 401 is fixedly connected inside the push assembly 40, and an inclined block 402 is slidably connected to the outer wall of the guide post 401. The roller 306 is in contact with the inclined block 402, and the inclined block 402 is slidably connected to the inner wall of the fixed frame 84. The pressure sensor 93 is fixedly installed on one side of the inclined block 402.

[0033] like Figures 3-6As shown, during prolonged tapping operations, the tapping head 53 is prone to wear. In this case, the controller 11 performs a wear detection operation on the tapping head 53 at regular intervals. During this time, the controller 11 causes the electric push rod 32 to drive the lifting frame 41, servo motor 42, coupling 51, tapping rod 52, and tapping head 53 to move upwards synchronously. Simultaneously, the servo motor 42 drives the tapping head 53 to rotate slowly, causing it to screw into the threaded groove 303 within the circular plate 302. The servo motor 42 then stops driving, creating a threaded engagement between the tapping head 53 and the circular plate 302. Afterwards, the controller 11 causes the electric push rod 32 to drive the tapping head 53, circular plate 302, two L-shaped lifting rods 301, limit plate 304, and roller 306 to move upwards a short distance synchronously, compressing the fourth spring 305 and causing the roller 306 to push upwards at an angle. Block 402 slides under the limit of guide post 401, thereby driving pressure sensor 93 to move a short distance and squeezing the second spring 92 through pressure sensor 93. At this time, the pressure value of pressure sensor 93 is maintained at a preset reference value. Then, through controller 11, servo motor 42 drives tapping head 53 to rotate slowly. During the rotation, through the thread engagement between tapping head 53 and thread groove 303, the circular plate 302, two L-shaped lifting rods 301, limit plate 304 and roller 306 slowly move down. If the pressure value of pressure sensor 93 continues to drop steadily and the fluctuation is within the preset normal wear range, it is judged that tapping head 53 is worn normally and can continue to be used. If the pressure value of pressure sensor 93 drops and the fluctuation exceeds the preset abnormal range, it is judged that tapping head 53 is abnormally worn or chipped and needs to be replaced. At this time, an alarm is triggered to remind the user to carry out maintenance. The above operation can be used to periodically and automatically detect the wear condition of the tapping head 53. Compared with the existing technology that relies on manual visual inspection, it can judge the degree of wear and give early warning for replacement, thus avoiding the production of defective products. If the tapping head 53 has completed its inspection and has rotated to the bottom of the tapping head 53, and the wear is determined to be normal, then the servo motor 42 will drive the tapping head 53 to slowly rotate in the opposite direction to reset it.
