Description

Technical Field

[0001] This invention relates to the field of flywheel misaligned slot hole processing technology, specifically to a flywheel misaligned slot hole processing device and processing method. Background Technology

[0002] A flywheel is a device that regulates the energy balance of a mechanical system by storing and releasing rotational kinetic energy. Its core function is to buffer speed fluctuations and stabilize power output. Common flywheel types include traditional metal flywheels, high-performance flywheels, and variable-speed flywheel sets. During flywheel machining, machine tools are used to machine displaced slots on different stepped surfaces of the flywheel by using a multi-axis moving gantry and drill bit.

[0003] For example, the patent publication number CN113787215A discloses an automatic drilling machine, which includes a main frame, a worktable installed on the upper end of the main frame, and sealing plates installed at both the front and rear ends of the main frame. The front end of the sealing plates has two sets of symmetrical heat dissipation holes. An electrical box is installed inside the main frame. A secondary frame is installed at the lower left end of the main frame. A slag changing box is installed on the upper end of the secondary frame. A door is installed at the front end of the slag changing box. The upper surface of the slag changing box is higher than the upper surface of the worktable. A workpiece is placed in the middle of the upper end of the worktable. A fixing mechanism and a driving mechanism are arranged sequentially from front to back on the upper end of the worktable. The fixing mechanism is located inside the workpiece, and the driving mechanism is located behind the workpiece.

[0004] Although the above-mentioned device solves the problem of debris collection, it still has the following drawbacks: After the drill bit has machined the flywheel into a slot, the worker needs to check the hole diameter of the machined slot. If the removed flywheel is found to have a smaller hole diameter (due to tool wear), the flywheel must be moved back to the machining platform for repositioning and machining. Since the flywheel is large and heavy, it is very inconvenient to move. Therefore, the existing machine tools for machining out-of-position slots lack an online detection structure for the diameter of the machined hole. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a flywheel misaligned slot hole processing device to solve the problems mentioned in the background technology, enabling online detection of the hole diameter after flywheel processing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flywheel misalignment slot machining device, comprising a machining platform installed in a machine tool, a multi-axis moving frame connected in the machine tool, a tool fixing shaft connected to one end of the multi-axis moving frame, and a drill bit connected in the tool fixing shaft. A limiting ring is sleeved on the outer side of the tool fixing shaft, and a U-shaped frame rod is fixedly connected to the outer wall of the limiting ring. A fixed seat is connected between the two crossbars of the U-shaped frame rod. A detection rod for detecting the flywheel hole diameter of the workpiece is fixedly connected to the bottom surface of the fixed seat. A marking ring is embedded on the outer side of the detection rod away from the fixed seat. The marking ring is tapered. A liquid storage core is movably placed inside the detection rod. A three-way groove communicating with the liquid storage core is opened at the center of the end of the detection rod with the marking ring. A screw cap for sealing the liquid storage core is threaded through the outer wall of the fixed seat end of the detection rod.

[0007] Furthermore, the detection rod has interconnected annular grooves, rectangular grooves, and openings. A metal trigger ring is fixedly connected in the annular groove, and a movable block is slidably connected in the rectangular groove. The end of the movable block passes through the opening and is slidably connected to it. The movable block is composed of an arc-shaped protrusion and a vertical plate. Two symmetrically arranged second springs are fixedly connected to the outer wall of the vertical plate of the movable block. The other end of the second spring is fixedly connected to the inner wall of the rectangular groove. The two second springs are located on both sides of the arc-shaped protrusion of the movable block. A metal trigger plate is fixedly connected to the side of the two vertical plates near the metal trigger ring. A cable is fixedly connected to the top of the metal trigger ring. After the cable passes through the detection rod, one end is connected to a buzzer. The buzzer is fixedly installed with a fixed base.

[0008] Furthermore, a wiping block is detachably connected to the bottom of the detection rod, and the wiping block is located below the marking ring.

[0009] Furthermore, a protective structure is connected to the outer side of the detection rod. The protective structure includes an upper protective plate and a lower protective plate. The upper protective plate is fixedly connected to the outer wall of the detection rod by a crossbar. Two symmetrically arranged vertical sliders are fixedly connected to the outer wall of the lower protective plate. The inner wall of the upper protective plate has a vertical groove corresponding to the vertical slider. A top plate is fixedly connected to the top of the lower protective plate. A first spring is fixedly connected to the top of the top plate. The other end of the first spring is fixedly connected to the upper protective plate. The bottom surface of the lower protective plate abuts against the top surface of the workpiece flywheel.

[0010] Furthermore, a limiting post is slidably connected to the center line of the first spring, the limiting post is fixedly connected to the upper protective plate, and the other end of the limiting post is slidably connected to the top plate.

[0011] Furthermore, an electric actuator is horizontally mounted on the U-shaped frame rod, and the output shaft of the electric actuator is fixedly mounted to the end of the fixed base. Two symmetrically arranged movable slots are opened on the top of the U-shaped frame rod, and movable blocks that are fixedly connected to the fixed base are slidably connected in the movable slots.

[0012] Furthermore, a fixed ring is fixedly connected to the bottom surface of the multi-axis moving frame, a top ring is fixedly connected to the top of the limiting ring and rotatably connected to the fixed ring, teeth are fixedly connected to the outer wall of the limiting ring, a motor is embedded in the multi-axis moving frame, a rotating gear is fixedly connected to the output end of the motor, and the rotating gear meshes with the teeth.

[0013] A processing method based on the above-mentioned flywheel misaligned slot hole processing device includes the following steps:

[0014] S1: When the drill bit descends to drill a hole on the workpiece flywheel, it drives the U-shaped support rod to descend synchronously, causing the detection rod and marking ring to descend into the already drilled slot. If the slot is qualified, the marking ring descends smoothly. If the hole diameter is too small, the inner wall of the hole will fit against the outer wall of the marking ring. As the detection rod continues to descend, a mark is drawn on the inner wall of the slot. The worker can use this mark to determine that the hole diameter is non-compliant. Without removing the workpiece flywheel, the worn drill bit can be replaced and the hole can be re-drilled.

[0015] S2: When the diameter of the slot is significantly smaller than expected, the inner wall of the slot will press against the movable block as the detection rod continues to descend. After being pressed, the movable block will slide in the opening or rectangular slot, causing the vertical plate of the movable block to slide, so that the metal trigger plate and the metal trigger ring come into contact. After the metal trigger ring is connected, the buzzer will be triggered to make a sound through the cable.

[0016] S3: When the detection rod descends, the wiping block will first contact the slot, and the wiping block can wipe the waste and debris in the slot clean.

[0017] S4: When the detection rod descends, the upper protective plate drives the lower protective plate to descend. During the drilling process, the upper and lower protective plates protect the position of the detection rod to prevent cutting fluid from entering the detection slot. As the drill bit continues to penetrate deeper, the upper protective plate slides outside the lower protective plate to ensure the smooth descent of the detection rod.

[0018] S5: When the detection rod follows the drill bit in the reset state, the lower protective plate is always in contact with the top surface of the workpiece flywheel under the action of the first spring. When the workpiece flywheel is driven to rotate by the processing platform, the lower protective plate can act as a scraper to scrape away the waste chips on the top surface of the workpiece flywheel.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This flywheel misalignment slot machining device features a synchronously lifting detection rod mounted on one side of the drill bit, with a marking ring at the bottom for marking. This design allows for real-time monitoring of the machined hole diameter using the detection rod and marking ring. If the hole diameter is too small, the worker can promptly detect the anomaly through the marking ring; simultaneously, the marking ring can also indicate whether the drill bit is worn. Thus, during the flywheel machining process, online monitoring of the drilled slot diameter is achieved, facilitating subsequent rework and accurate assessment of drill bit wear, thereby improving processing efficiency and quality control.

[0021] This flywheel misalignment slot processing device, through the coordinated operation of a movable block, a metal trigger plate and a metal trigger ring, and a buzzer, can provide an immediate alarm when the slot diameter is smaller than the specified size. When the smaller-than-expected diameter is detected, the movable block will slide due to compression. This action will trigger the metal trigger plate to contact the metal trigger ring, thereby activating the buzzer to sound an alarm. This design can alert workers to significant processing discrepancies even without visually observing markings, facilitating rapid corrective action and ensuring product quality while improving production efficiency.

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Please see Figures 1-8 A flywheel misalignment slot machining device includes a machining platform 2 installed in a machine tool, a multi-axis moving frame 1 connected in the machine tool, a tool fixing shaft 7 connected to one end of the multi-axis moving frame 1, and a drill bit 3 connected in the tool fixing shaft 7. A limiting ring 13 is sleeved on the outer side of the tool fixing shaft 7. A U-shaped frame rod 4 is fixedly connected to the outer wall of the limiting ring 13. A fixed seat 11 is connected between the two crossbars of the U-shaped frame rod 4. A detection rod 8 for detecting the diameter of the flywheel 6 hole in the workpiece is fixedly connected to the bottom surface of the fixed seat 11. A marking ring 16 is embedded on the outer side of the end of the detection rod 8 away from the fixed seat 11. The marking ring 16 is tapered. A liquid storage core 26 is movably placed inside the detection rod 8. A three-way groove 30 communicating with the liquid storage core 26 is opened at the center of the end of the detection rod 8 with the marking ring 16. A screw cap 23 for sealing the liquid storage core 26 is threaded through the outer wall of the fixed seat 11 at one end of the detection rod 8.

[0033] In the flywheel misaligned slot processing device of the present invention, when the drill bit 3 is performing drilling operations, the multi-axis moving frame 1 descends, the tool fixing shaft 7 rotates, and the drill bit 3 descends at the same time, driving the U-shaped frame rod 4 to descend synchronously, driving the detection rod 8 and the marking ring 16 to descend into the slot that has been drilled. The detection rod 8 can detect the slot that has been drilled.

[0034] When the slot is of acceptable diameter, the marking ring 16 descends smoothly. When the slot diameter is too small, the inner wall of the hole will fit against the outer wall of the marking ring 16. As the detection rod 8 continues to descend, a mark is drawn on the inner wall of the slot. Based on this mark, the worker can determine that the hole diameter is non-compliant and replace the worn drill bit 3 to re-drill the hole without removing the workpiece flywheel 6.

[0035] The marking ring 16 is tapered to facilitate its smooth sliding into the slot. Since the slot diameter has a standard value, the diameter of the marking ring 16 can be set according to the standard value. That is, the diameter of the marking ring 16 can be set to be the same as the standard value. When the hole diameter is smaller than the standard diameter, it will be marked by the marking ring 16 to remind the worker that the hole diameter is smaller than the standard value.

[0036] The detection rod 8 is equipped with a liquid storage core 26. The liquid is smoothly introduced into the marking ring 16 through the three-way groove 30, so that the marking ring 16 always maintains the function of a marker pen. The marking ring 16 can be a fiber pen tip, a plastic microporous pen tip, or a nylon hard pen tip. This ensures both smooth liquid flow and wear resistance of the marking ring 16.

[0037] The cap 23 seals the liquid storage core 26 and can be unscrewed from the end of the detection rod 8, making it convenient to replace the liquid storage core 26.

[0038] A synchronously lifting detection rod 8 is installed on one side of the drill bit 3, and a marking ring 16 is provided at the bottom of the detection rod for marking. This structural design allows for real-time detection of the diameter of the machined hole using the detection rod 8 and the marking ring 16. When the hole diameter is too small, the worker can promptly detect the abnormality through the marking on the marking ring 16; simultaneously, the marking ring 16 can also be used to determine whether the drill bit 3 has worn. Thus, during the machining of the workpiece flywheel 6, online detection of the diameter of the drilled slot is achieved, facilitating subsequent rework and accurate assessment of the wear condition of the drill bit 3, thereby improving machining efficiency and quality control.

[0039] As a preferred embodiment of the present invention, the detection rod 8 has an interconnected annular groove 32, a rectangular groove 33, and an opening 34. A metal trigger ring 27 is fixedly connected in the annular groove 32, and a movable block 21 is slidably connected in the rectangular groove 33. The end of the movable block 21 passes through the opening 34 and is slidably connected to the opening 34. The movable block 21 is composed of an arc-shaped protrusion and a vertical plate. Two symmetrically arranged second springs 35 are fixedly connected to the outer wall of the vertical plate of the movable block 21. The other end of the second spring 35 is fixedly connected to the inner wall of the rectangular groove 33. The two second springs 35 are located on both sides of the arc-shaped protrusion of the movable block 21. A metal trigger plate 29 is fixedly connected to the side of the two vertical plates near the metal trigger ring 27. A cable 31 is fixedly connected to the top of the metal trigger ring 27. After the cable 31 passes through the detection rod 8, one end is connected to a buzzer 10. The buzzer 10 is fixedly installed with the fixed base 11.

[0040] Specifically, when the diameter of the slot is significantly smaller than expected, the marking ring 16 continuously marks the slot as the detection rod 8 descends. At the same time, the inner wall of the slot will press against the movable block 21. After being pressed, the movable block 21 will slide within the opening 34 and the rectangular slot 33, causing the vertical plate of the movable block 21 to slide, so that the metal trigger plate 29 abuts against the metal trigger ring 27. After the metal trigger ring 27 is connected, the buzzer 10 is triggered to make a sound through the cable 31.

[0041] Under normal circumstances, the movable block 21 is pulled by the second spring 35, which keeps the metal trigger plate 29 away from the metal trigger ring 27, thus preventing the buzzer 10 from sounding an alarm. When the diameter is too small, the movable block 21 is compressed, the second spring 35 is stretched, causing the metal trigger plate 29 to contact the metal trigger ring 27, and thus sounding an alarm.

[0042] Through the coordinated operation of the movable block 21, the metal trigger plate 29, the metal trigger ring 27, and the buzzer 10, an immediate alarm can be provided when the diameter of the slot is smaller than the specified size. When the smaller diameter is detected, the movable block 21 will slide due to compression. This action will trigger the metal trigger plate 29 to contact the metal trigger ring 27, thereby activating the buzzer 10 to sound an alarm. This design can alert workers to significant processing discrepancies even without visually observing markings, facilitating rapid corrective action and ensuring product quality while improving production efficiency. In practical applications, after the buzzer 10 sounds the alarm, it can force the multi-axis moving frame 1 to reset, stopping the drilling operation.

[0043] As a preferred embodiment of the present invention, a wiping block 20 is detachably connected to the bottom of the detection rod 8, and the wiping block 20 is located below the marking ring 16.

[0044] Specifically, when the detection rod 8 is about to enter the slot, the wiping block 20 can first wipe away the iron filings in the slot to prevent the detection from being affected.

[0045] As a preferred embodiment of the present invention, a protective structure is also connected to the outer side of the detection rod 8. The protective structure includes an upper protective plate 5 and a lower protective plate 9. The upper protective plate 5 is fixedly connected to the outer wall of the detection rod 8 by a crossbar. Two symmetrically arranged vertical sliders 36 are fixedly connected to the outer wall of the lower protective plate 9. The inner wall of the upper protective plate 5 is provided with a vertical groove 38 corresponding to the vertical sliders 36. A top plate 37 is fixedly connected to the top of the lower protective plate 9. A first spring 24 is fixedly connected to the top of the top plate 37. The other end of the first spring 24 is fixedly connected to the upper protective plate 5. The bottom surface of the lower protective plate 9 abuts against the top surface of the workpiece flywheel 6.

[0046] Specifically, when the detection rod 8 descends, the upper protective plate 5 drives the lower protective plate 9 to descend. During the drilling process, the upper protective plate 5 and the lower protective plate 9 protect the position of the detection rod 8 to prevent cutting fluid from entering the detection slot. As the drill bit 3 continues to penetrate deeper, the upper protective plate 5 slides outside the lower protective plate 9 to ensure the smooth descent of the detection rod 8. This ensures that during the drilling operation, the upper protective plate 5 and the lower protective plate 9 can always protect the detection rod 8 to prevent oil from entering the detection hole and causing the mark to become invalid.

[0047] After the drill bit 3 rises, the upper protective plate 5 and the lower protective plate 9 extend under the action of the first spring 24. At this time, the lower protective plate 9 always presses against the top surface of the workpiece flywheel 6. When the processing platform 2 rotates and drives the workpiece flywheel 6 to rotate, the lower protective plate 9 acts like a scraper to scrape off the cutting fluid on the surface of the workpiece flywheel 6, making the detection effect better. Moreover, most of the slots are through holes, and the oil can fall smoothly from the hole diameter.

[0048] During drilling, the drill bit 3 is driven down by the multi-axis moving frame 1 and rotates on its own under the rotation of the tool fixing shaft 7. When the drill bit 3 descends to contact the surface of the flywheel 6, the drill bit 3 drills a hole in the surface of the flywheel 6 (this is the prior art).

[0049] At the same time, the detection rod 8 is fixed to the bottom surface of the multi-axis moving frame 1 by the limiting ring 13 and the fixing ring 14 at the end of the U-shaped frame rod 4. In other words, the U-shaped frame rod 4 is not affected by the rotation of the tool fixing shaft 7 and the drill bit 3, but only moves up and down with the multi-axis moving frame 1.

[0050] When the drill bit 3 descends, it drives the U-shaped support rod 4, the detection rod 8, and the upper protective plate 5 to descend. At this time, the upper protective plate 5 will slide on the outside of the lower protective plate 9 (the vertical groove 38 and the vertical slider 36 mentioned below). In this way, the upper and lower protective plates can always prevent the cutting fluid from splashing onto the bottom of the detection rod 8, which would cause the mark to become invalid.

[0051] Before the drill bit 3 descends, the upper protective plate 5 and the lower protective plate 6 are always in the extended state under the influence of the elastic potential energy of the first spring 24. This setting can provide sufficient protection. At the same time, after the drill bit 3 rises, the flywheel 6 needs to rotate to change the drilling position. The flywheel 6 rotates due to the rotation of the motor, so that the bottom surface of the lower protective plate 6, which is in contact with the surface of the flywheel 6, can push the waste chips and impurities on the surface of the flywheel 6, which can have a scraping effect and prevent waste chips from directly entering the hole that has just been drilled (because when the drill bit 3 descends again, the hole that has just been drilled needs to be inspected).

[0052] As a preferred technical solution of the present invention, a limiting post 28 is slidably connected to the center line position of the first spring 24, the limiting post 28 is fixedly connected to the upper protective plate 5, and the other end of the limiting post 28 is slidably connected to the top plate 37.

[0053] Specifically, when the upper protective plate 5 descends, the vertical groove 38 on the inner wall of the upper protective plate 5 slides outside the vertical slider 36 on the outer wall of the lower protective plate 9. At this time, the first spring 24 is compressed, and the limiting post 28 ensures the vertical stability of the first spring 24 when it is compressed, preventing the first spring 24 from bending and deforming and losing its spring effect.

[0054] As a preferred embodiment of the present invention, an electric actuator 12 is horizontally mounted on the U-shaped frame rod 4. The output shaft of the electric actuator 12 is fixedly mounted to the end of the fixed base 11. Two symmetrically arranged moving slots 22 are opened on the top of the U-shaped frame rod 4. A moving block 25 fixedly connected to the fixed base 11 is slidably connected in the moving slot 22.

[0055] Specifically, since the hole diameters on flywheels 6 of different workpieces vary, the distance between two adjacent slots needs to be adjusted. Once the hole diameter and the distance between the two holes are known, the electric push rod 12 can be controlled by the operating end of the machining tool to move the fixed seat 11 on the U-shaped frame rod 4, causing the moving block 25 on the ground of the fixed seat 11 to slide in the moving groove 22 of the U-shaped frame rod 4, so that after each descent of the drill bit 3, the detection rod 8 can match a newly drilled slot.

[0056] In addition, each drill bit 3 can be matched with a detection rod 8. Since the moving groove 22 here is a through groove at the end of the U-shaped frame rod 4, when it is necessary to replace the detection rod 8 that matches the slot (drill bit 3), it is only necessary to open the connection between the electric push rod 12 and the fixed seat 11, and the fixed seat 11 can be removed from the U-shaped frame rod 4, which makes it easy to remove the detection rod 8.

[0057] As a preferred technical solution of the present invention, a fixed ring 14 is fixedly connected to the bottom surface of the multi-axis moving frame 1, a top ring 17 that is rotatably connected to the fixed ring 14 is fixedly connected to the top of the limiting ring 13, teeth 19 are fixedly connected to the outer wall of the limiting ring 13, a motor 18 is embedded in the multi-axis moving frame 1, a rotating gear 15 is fixedly connected to the output end of the motor 18, and the rotating gear 15 is meshed with the teeth 19.

[0058] Specifically, since the hole diameters on flywheel 6 of different workpieces vary, not only does the distance between two adjacent slots need to be adjusted, but the position of the detection rod 8 also needs to rotate around the axis of drill bit 3. After knowing the hole diameter and the distance between the two holes, the motor 18 can be controlled to operate, so that its output shaft drives the rotating gear 15 to mesh with the teeth 19, thereby driving the limit ring 13 to rotate. This causes the fixed ring 17 at the top of the limit ring 13 to rotate within the top ring 14, so that the limit ring 13 drives the U-shaped frame rod 4 to rotate when it rotates.

[0059] A processing method based on the above-mentioned flywheel misaligned slot hole processing device includes the following steps:

[0060] S1: When drill bit 3 descends to drill a hole on workpiece flywheel 6, it drives U-shaped support rod 4 to descend synchronously, driving detection rod 8 and marking ring 16 to descend into the already drilled slot; for qualified slots, marking ring 16 descends smoothly; for smaller hole diameters, the inner wall of the hole will fit against the outer wall of marking ring 16. As detection rod 8 continues to descend, a mark is drawn on the inner wall of the slot. Workers can use this mark to determine that the hole diameter is non-compliant, and replace the worn drill bit 3 and re-drill without removing workpiece flywheel 6.

[0061] S2: When the diameter of the slot is significantly smaller than expected, the inner wall of the slot will press against the movable block 21 as the detection rod 8 continues to descend. After being pressed, the movable block 21 will slide in the opening 34 and the rectangular slot 33, causing the vertical plate of the movable block 21 to slide, so that the metal trigger plate 29 and the metal trigger ring 27 come into contact. After the metal trigger ring 27 is connected, the buzzer 10 will be triggered to make a sound through the cable 31.

[0062] S3: When the detection rod 8 descends, the wiping block 20 will first contact the slot hole, and the wiping block 20 can wipe the waste and debris in the slot hole clean.

[0063] S4: When the detection rod 8 descends, the upper protective plate 5 drives the lower protective plate 9 to descend. When the drill bit 3 is drilling, the upper protective plate 5 and the lower protective plate 9 protect the position of the detection rod 8 to prevent the cutting fluid from entering the detection slot. As the drill bit 3 continues to go deeper, the upper protective plate 5 slides on the outside of the lower protective plate 9 to ensure the smooth descent of the detection rod 8.

[0064] S5: When the detection rod 8 is in the reset state following the drill bit 3, the lower protective plate 9 is always in contact with the top surface of the workpiece flywheel 6 under the action of the first spring 24. When the workpiece flywheel 6 is driven to rotate by the processing platform 2, the lower protective plate 9 can act as a scraper to scrape away the waste chips on the top surface of the workpiece flywheel 6.

[0065] In the above structure, the electric actuator 12, motor 18, and buzzer 10 are all existing mature technologies, so they will not be described in detail here. After the last slot is completed, the workpiece flywheel 6 can rotate once more to inspect the last slot. That is, the workpiece flywheel 6 rotates once more to allow the drill bit 3 to enter the first slot and the inspection rod 8 to inspect the last slot.

[0066] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

5. A processing method based on the flywheel misaligned slot processing device according to any one of claims 1-4, comprising the following steps: S1: When the drill bit (3) descends to drill a hole on the workpiece flywheel (6), it drives the U-shaped frame rod (4) to descend synchronously, driving the detection rod (8) and the marking ring (16) to descend into the already drilled slot; if the slot is qualified, the marking ring (16) descends smoothly; if the hole diameter is too small, the inner wall of the hole diameter will fit against the outer wall of the marking ring (16). As the detection rod (8) continues to descend, a mark is drawn on the inner wall of the slot. Based on the mark, the worker can determine that the hole diameter is not compliant. Without removing the workpiece flywheel (6), the worn drill bit (3) is replaced and the hole is re-drilled. S2: When the diameter of the slot is too small, the inner wall of the slot will press against the movable block (21) as the detection rod (8) continues to descend. After being pressed, the movable block (21) will slide in the opening (34) and the rectangular slot (33), causing the vertical plate of the movable block (21) to slide, so that the metal trigger plate (29) and the metal trigger ring (27) come into contact. After the metal trigger ring (27) is connected, the buzzer (10) will be triggered through the cable (31) to make a sound. S3: When the detection rod (8) descends, the wiping block (20) will first contact the slot, and the wiping block (20) will wipe the waste in the slot clean; S4: When the detection rod (8) descends, the upper protective plate (5) drives the lower protective plate (9) to descend. When the drill bit (3) is drilling, the upper protective plate (5) and the lower protective plate (9) protect the position of the detection rod (8) to prevent the cutting fluid from entering the detection slot. As the drill bit (3) continues to go deeper, the upper protective plate (5) slides on the outside of the lower protective plate (9) to ensure the smooth descent of the detection rod (8). S5: When the detection rod (8) is in the reset state following the drill bit (3), the lower protective plate (9) is always in contact with the top surface of the workpiece flywheel (6) under the action of the first spring (24). When the workpiece flywheel (6) is driven to rotate by the processing platform (2), the lower protective plate (9) can act as a scraper to scrape away the waste on the top surface of the workpiece flywheel (6).
