Description

Technical Field

[0001] This invention relates to the field of diamond synthesis technology, and more particularly to a six-sided top press suitable for the synthesis of large-size diamonds. Background Technology

[0002] The six-sided top-pressure press is currently the main high-pressure equipment for synthesizing superhard materials such as synthetic diamond and cubic boron nitride, as well as electronic special materials such as laser crystals, sapphire single crystals, and nonlinear optical crystals. This equipment uses six top-pressure units to synchronously drive the top hammers, completing the material synthesis under high pressure and high temperature conditions. With the increasing demand for large-size diamonds and other high-end materials, higher requirements are being placed on the automation level and operational reliability of the synthesis equipment.

[0003] Regarding the safe operation of six-sided jacking presses, some technical solutions have been proposed for improvement. For example, Chinese invention patent application number 202411546432.2 discloses a six-sided jacking press that, by setting a pressure relief port and a pressure relief mechanism on the inlet pipe, in the event of a blasting accident, the jacking hammer pushing transmission component drives the switching mechanism to open the connecting pipe channel, causing the hydraulic cylinder inlet end to lose hydraulic power and preventing the jacking hammers from squeezing each other and causing damage. This solution mainly solves the safety protection problem in the event of sudden equipment failure, but it still does not address the daily maintenance, surface cleaning, and condition monitoring of the jacking hammers.

[0004] In existing technologies, the top hammers of six-sided top presses are prone to developing residual impurities such as pyrophyllite and graphite on their surface under long-term high-pressure and high-temperature cyclic conditions. Furthermore, the top hammers themselves may develop defects such as microcracks or loosening. These problems directly affect the quality of subsequent synthesized products and can even lead to damage to the top hammers under high pressure, causing equipment downtime and safety risks.

[0005] Currently, the cleaning and inspection of the top hammer mainly relies on manual operation. Operators need to enter the confined space after the equipment has cooled down and been depressurized, judge the condition of the top hammer by tapping and listening to the sound, and manually clean surface impurities. This method has the following shortcomings: First, the inspection results depend on personal experience, which is highly subjective and makes it difficult to guarantee accuracy and consistency; second, manual operation is inefficient and prolongs the non-productive time of the equipment; third, the top hammer is large and the installation position is small, making it difficult for manual personnel to fully cover the cleaning and inspection area, and blind spots are likely to exist; fourth, it is impossible to achieve automated integration of cleaning and inspection, which makes it difficult to meet the needs of intelligent manufacturing for equipment self-diagnosis and self-maintenance. Summary of the Invention

[0006] The purpose of this invention is to solve the problems of existing six-sided top presses, which rely on manual cleaning and tapping for sound detection of the top hammer, resulting in strong subjectivity, low efficiency, incomplete coverage, inability to achieve automated connection, and difficulty in meeting the self-diagnosis and self-maintenance requirements of large-size high-end material synthesis. Therefore, this invention proposes a six-sided top press suitable for large-size diamond synthesis.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A six-sided pressing machine suitable for the synthesis of large-size diamonds includes six pressing units, with gaps between two adjacent pressing units, and a detection mechanism is provided at the gap position; The detection mechanism includes a reversing component, which includes an outer frame and an inner frame movably connected to the inside of the outer frame. A reversing drive structure for driving the inner frame to switch between an avoidance state and a working state is provided between the outer frame and the inner frame. The inner frame is equipped with a detection unit for detecting the status of the top hammer of the top pressing unit and a maintenance unit for maintaining the top hammer.

[0008] In some embodiments, the reversing drive structure includes a first telescopic member disposed at one end of the outer frame, the telescopic end of the first telescopic member being provided with a push plate, and the inner frame being provided with an inclined plate at one end near the first telescopic member. In the initial state, the inner frame and the outer frame are set at a non-horizontal angle, forming the avoidance state, and the bottom ends of the push plate and the inclined plate correspond to each other; When the first telescopic component extends, the push plate acts on the inclined surface of the inclined plate, driving the inner frame to flip to a horizontal state, thus forming the working state; The outer frame and the inner frame are rotatably connected by a hinge column, and a torsion spring is provided between them for the inner frame to return to its original position after rotation.

[0009] In some embodiments, a first locking mechanism is provided between the push plate and the inclined plate for locking the position of the inner frame after it is turned horizontal.

[0010] In some embodiments, a set of detection mechanisms is provided in the gaps between the four top pressing units in the horizontal direction. Two adjacent sets of detection mechanisms can work synchronously to perform maintenance and status detection on different areas of the same top hammer.

[0011] In some embodiments, the detection unit includes a striking part, the striking part including an extension tube communicating with the interior of the outer frame, a telescopic column being elastically and movably connected inside the extension tube, the end of the telescopic column near the inner frame being provided with a curved surface, and the end of the telescopic column away from the inner frame being provided with a striking head. The inner side of the inner frame is provided with a second telescopic member, and the telescopic end of the second telescopic member is provided with a push plate, which is used to push the curved end of the telescopic column so that the telescopic column extends outward to strike the top hammer.

[0012] In some embodiments, the inner frame is provided with an opening at a position corresponding to the extension tube, and a second locking mechanism is provided in the opening for locking the telescopic column in a retracted state after the curved end of the telescopic column is pushed into the opening. The extension tube or the outer frame is equipped with a sound detector to collect the sound signal generated when the striking head strikes the top hammer, so as to determine the structural integrity of the top hammer.

[0013] In some embodiments, the maintenance unit includes a cleaning assembly, which includes a rotating motor. The rotating end of the rotating motor is provided with a rotating cover, and the rotating cover is provided with a nozzle and a cleaning rod corresponding to the top hammer. The rotating motor has a mounting plate at one end away from the rotating cover. A force-transmitting spring is provided between the mounting plate and the telescopic end of the second telescopic member, which is used to drive the cleaning assembly to move horizontally through the telescopic extension of the second telescopic member.

[0014] In some embodiments, the cleaning rod includes a fixed section and an elastic section. The fixed section is fixedly connected to the rotating cover. A pressure sensor is provided between the fixed section and the elastic section to detect the contact pressure between the cleaning rod and the top hammer, so as to determine the degree of cleanliness of the top hammer surface.

[0015] In some embodiments, the mounting plate is provided with an electromagnetic pin, and the inner frame has multi-level locking holes adapted to the electromagnetic pin, for locking the cleaning component in different horizontal positions to meet the maintenance needs of top hammers of different specifications.

[0016] In some embodiments, the first locking mechanism and the second locking mechanism are electromagnetic pins.

[0017] Compared with the prior art, the present invention provides a six-sided top press suitable for the synthesis of large-size diamonds, which has the following beneficial effects.

[0018] 1. This invention, by setting a hinge column and a torsion spring between the inner and outer frames, allows the inner frame to maintain an inclined posture in the assembled state, causing the cleaning component and the striking part to retract as a whole into the corner of the gap between the top pressing unit, completely withdrawing from the working area of ​​the six top hammers. This avoidance structure achieves spatial separation between the detection mechanism and the assembly chamber without affecting the original hinge layout, avoiding interference with the high-pressure assembly process and ensuring the effective volume of the assembly chamber and process safety.

[0019] 2. This invention employs three cleaning methods: air jet cleaning, elastic cleaning rod scraping, and tapping vibration. A pressure sensor provides real-time feedback on the cleaning level, enabling adaptive removal of stubborn impurities. After cleaning, a second telescopic component drives a telescopic column to automatically tap the top hammer. Combined with a sound detector and voiceprint recognition algorithm, this allows for an objective assessment of whether the top hammer is cracked or loose. The entire process is automated, reducing reliance on manual labor and improving the consistency and reliability of the test results.

[0020] 3. This invention incorporates multi-level locking holes and electromagnetic pins between the mounting plate and the inner frame, allowing the cleaning assembly to be horizontally locked according to different sized top hammers, achieving targeted cleaning. When a single top hammer is too large, two adjacent detection mechanisms can respectively cover the left and right areas of the top hammer, simultaneously performing cleaning and tapping detection without interference. This structure effectively solves the problem of covering large-sized top hammers and improves the equipment's adaptability to products of different specifications.

[0021] 4. This invention, through the cooperation of the second telescopic component and the force transmission spring, utilizes the rotating cover of the cleaning assembly to automatically push the synthesized pyrophyllite medium out of the center of the six top hammers, freeing up space for subsequent cleaning and inspection. Simultaneously, after the cleaning assembly is locked by the electromagnetic pin, the extension and retraction of the second telescopic component only affects the striking action, achieving structural decoupling of the three functions of "positioning, cleaning, and striking," resulting in more precise movements and effectively improving overall work efficiency.

[0022] Other advantages, objectives and features of the invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be learned from practice of the invention.

Detailed Implementation

[0034] 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.

[0035] Reference Figures 1 to 2 A six-sided pressing machine suitable for the synthesis of large-size diamonds includes six pressing units 1. There is a gap between two adjacent pressing units 1; specifically, there are gaps between the four pressing units 1 located in the horizontal direction and between the two pressing units 1 located at different heights.

[0036] Continue reading Figure 3 As shown, a detection mechanism 2 is provided in the gap between two adjacent pressing units 1. A hinge structure is provided between the pressing units 1, and the hinge structure corresponding to the gap between the four pressing units 1 in the horizontal direction is relatively large, providing installation and movement space for the detection mechanism 2.

[0037] Please continue reading. Figures 3 to 6 As shown, the detection mechanism 2 includes a reversing component 3. The reversing component 3 includes an outer frame 301 and an inner frame 302, with the inner frame 302 located inside the outer frame 301.

[0038] Please continue reading. Figure 7As shown, the outer frame 301 and the inner frame 302 are rotatably connected by a hinge post 305. A torsion spring is provided between the outer frame 301 and the inner frame 302 at a position corresponding to the hinge post 305. The torsion spring is used to reset the inner frame 302 after rotation.

[0039] like Figure 4 As shown, a first telescopic member 3011 is provided at one end of the outer frame 301.

[0040] The telescopic end of the first telescopic member 3011 is provided with a first push plate 303. Preferably, a deformation compensation pad is provided at the connection between the telescopic end of the first telescopic member 3011 and the first push plate 303. This pad can generate a certain elastic deformation to compensate for assembly errors, reduce transmission impact, and avoid rigid contact wear. The inner frame 302 is provided with an inclined plate 304 at one end near the first telescopic member 3011. The first telescopic member 3011 is preferably a hydraulic cylinder.

[0041] Initially, the inner frame 302 and the outer frame 301 are set at a non-horizontal angle, and the bottom end of the inclined plate 304 is close to the first push plate 303. Through the extension of the first telescopic member 3011, the first push plate 303 is driven to act on the inclined surface of the inclined plate 304, causing the inner frame 302 to overcome the torsion spring force and rotate until the inner frame 302 changes from an inclined state to a horizontal state. Figure 5 As shown.

[0042] A first locking mechanism is provided between the first push plate 303 and the inclined plate 304. This first locking mechanism is used to lock the position of the inner frame 302 after the inner frame 302 has turned horizontal, by locking the first push plate 303 to the outer frame 301. Figure 4 As shown, an insertion hole 3041 corresponding to the telescopic end of the first locking mechanism is provided on the inclined plate 304. The first locking mechanism can be an electromagnetic pin.

[0043] like Figures 4 to 6 As shown, the outer frame 301 has a striking part 4 on its outer side, which is obliquely aligned with the hammer direction of the pressing unit 1.

[0044] like Figure 7 , Figure 9 and Figure 10 As shown, as an example of the striking part 4, the striking part 4 includes an extension cylinder 401 that communicates with the interior of the outer frame 301. A telescopic column 402 is elastically and movably connected inside the extension cylinder 401.

[0045] Specifically, the internal channel of the extension cylinder 401 is provided with a return spring 4011, the telescopic column 402 is elastically connected to the extension cylinder 401 through the return spring 4011, and the telescopic column 402 is provided with a pressure plate 4022 that is fixedly connected to the return spring 4011.

[0046] As an option, such Figure 9 As shown, the telescopic column 402 can be configured as a two-section structure, including an inner column 403 and an outer column 404. A compensating spring 4032 is provided between the outer column 404 and the inner column 403 to prevent the telescopic column 402 from making hard contact with the top hammer of the top pressing unit 1 after it extends outward, thus playing a buffering and protective role. Specifically, a limiting groove 4031 is provided on the side of the inner column 403 near the outer column 404, and a limiting rod 4041 is provided on the side of the outer column 404 near the inner column 403. The end of the limiting rod 4041 away from the outer column 404 is fixedly connected to the inside of the limiting groove 4031 through the compensating spring 4032. The cooperation between the limiting rod 4041 and the limiting groove 4031 can limit the extension and retraction stroke of the telescopic column 402, prevent the compensating spring 4032 from excessively deforming and failing, and at the same time ensure stable striking force and uninterrupted sound wave acquisition.

[0047] like Figure 10 As shown, the end of the telescopic column 402 closest to the inner frame 302 is curved. The end of the telescopic column 402 furthest from the inner frame 302 is provided with a striking head 4021, which is a detachable structure and can be replaced.

[0048] A second telescopic member 306 is provided on the inner side of the inner frame 302, and a second push plate 3061 is provided at the telescopic end of the second telescopic member 306. The second telescopic member 306 is preferably a hydraulic cylinder.

[0049] Among them, such as Figure 10 As shown, openings are provided on both sides of the inner frame 302 corresponding to the positions of the extension cylinder 401, and a second locking mechanism is provided inside the openings. The second locking mechanism is used to lock the retracted state of the telescopic column 402 after the curved end of the telescopic column 402 is squeezed and retracted. Specifically, after the curved end of the telescopic column 402 is pushed into the opening of the inner frame 302 by the second push plate 3061, the second locking mechanism is activated, its telescopic end closes the opening of the inner frame 302, and pushes the curved end of the telescopic column 402, causing the telescopic column 402 to further retract into the extension cylinder 401 until locking is completed. The second locking mechanism can be an electromagnetic pin.

[0050] It should be added that when the inner frame 302 rotates past the curved end of the telescopic column 402 via the hinge column 305, the telescopic column 402 is also retracted into the extension cylinder 401 by compression. The inner side of the opening is designed as a smooth curved surface, and the torque of the torsion spring is greater than the elastic force of the return spring 4011. When the first telescopic member 3011 retracts and the first push plate 303 disengages from the inclined plate 304, the inner frame 302, under the rebound force of the torsion spring on the hinge column 305, presses the telescopic column 402 and returns to its inclined position.

[0051] Similarly, when the first telescopic member 3011 pushes forward again to contact and press the inclined plate 304 at the end of the inner frame 302, so that the inner frame 302 is adjusted to a horizontal state again, the smooth curved surface inside the opening and the curved end of the telescopic column 402 are used to press the curved end of the telescopic column 402 to retract into the extension cylinder 401, thereby realizing the conversion of the inner frame 302 to a tilted or horizontal state.

[0052] Optionally, depending on the usage requirements, a baffle (not shown in the figure) can be provided at the top of the inner frame (302) and at the position corresponding to the opening on the inner frame 302. The baffle will always keep pressing the curved end of the telescopic column 402 during the rotation of the inner frame 302, so as to improve the stability of the connection between the telescopic column 402 and the opening on the inner frame 302.

[0053] Alternatively, an electromagnet can be installed inside the extension cylinder 401, and an adsorption section corresponding to the electromagnet can be provided on the curved end of the telescopic column 402. When the inner frame 302 rotates and is pressed into the inside of the extension cylinder 401, the electromagnet is energized and activated. By adsorbing the curved end of the telescopic column 402, the position of the telescopic column 402 is maintained. At this time, the inner frame 302 is in an inclined state. Subsequently, when the inner frame 302 is readjusted to be horizontal, the electromagnet is de-energized and closed. Under the action of the return spring 4011, the telescopic column 402 rebounds and enters the opening of the inner frame 302, and extends to the inner side of the inner frame 302.

[0054] Please continue reading. Figure 5 and Figure 6 As shown, the inner frame 302 houses a cleaning assembly 5. As one example, the cleaning assembly 5 includes a rotating motor 501, with a rotating cover 502 at its rotating end. The rotating cover 502 has a nozzle corresponding to the top hammer and a cleaning rod 505. The cleaning rod 505 includes a fixed section fixedly connected to the rotating cover 502 and an elastic section fixedly connected to the fixed section. A pressure sensor is provided between the fixed section and the elastic section. Preferably, a friction layer can be provided on the outer side of the elastic section to increase the friction with residue on the top hammer.

[0055] A mounting plate 503 is provided at the end of the rotating motor 501 away from the rotating cover 502. A force transmission spring 504 is fixedly connected between the mounting plate 503 and the second push plate 3061. The second push plate 3061 and the mounting plate 503 are connected to the inner frame 302 for movable limitation, so that the extension and retraction of the second telescopic member 306 can drive the cleaning assembly 5 to move horizontally through the force transmission spring 504.

[0056] like Figure 7 and Figure 8As shown, an electromagnetic pin is provided on the mounting plate 503, and a slide with multiple locking holes is opened on the inner side of the inner frame 302 to lock the cleaning component 5 in different horizontal positions to accommodate top hammers of different specifications.

[0057] The specific working principle is as follows: The working principle and beneficial effects of the present invention will be explained in stages according to the order of the synthesis process.

[0058] When a six-sided press is used for large-size diamond synthesis, the six top hammers need to work closely together to compress the pyrophyllite blocks (medium). The extension and retraction distances of the top hammers are controlled by hydraulic cylinders. If the detection mechanism 2 is left between the hammers for an extended period, it will occupy the synthesis space or be damaged by high pressure. Therefore, it must be completely removed from the working area when not in use.

[0059] During the assembly process, the first telescopic component 3011 is in a retracted state. At this time, the inner frame 302 is tilted relative to the outer frame 301 under the action of the torsion spring, as shown below. Figure 4 and Figure 7 As shown. Due to the tilt of the inner frame 302, the entire cleaning assembly 5 and the striking part 4 also tilt accordingly, retracting into the corner of the press's gap. This prevents them from occupying the processing space of the six top hammers on the pyrophyllite medium in the six top pressure units 1, thus placing them within the safe working area. This ensures complete avoidance of the detection and execution mechanisms within the working area, maximizing the effective space of the synthesis chamber and preventing interference with the high-pressure synthesis process.

[0060] After the synthesis is completed and the top hammer retracts, the detection mechanism 2 needs to be inserted into the gap between the top hammers. Because the top hammers are large and the gap is small, straight-line movement is prone to collisions, so a deflection mechanism is needed to ensure smooth intervention.

[0061] At this time, the first telescopic component 3011 is activated, and its telescopic end extends forward, driving the first push plate 303 to move forward and contact and press the inclined plate 304 at the end of the inner frame 302. Due to the effect of the inclined surface of the inclined plate 304, the horizontal thrust is converted into a torque that causes the inner frame 302 to rotate around the hinge post 305. As the first telescopic component 3011 continues to extend, the inner frame 302 gradually changes from an inclined state to a horizontal state. At this time, the rotating cover 502 corresponds to the center point pointed to by the six top pressing units 1. When it turns to a horizontal state, the first locking mechanism (electromagnetic pin) is activated, and its telescopic end is inserted into the insertion hole 3041 on the inclined plate 304, locking the inner frame 302 in a horizontal working state. The inclined surface drive achieves smooth direction change and avoids hard impact; the torsion spring ensures that the mechanism automatically resets in case of power failure or other abnormalities, improving safety; and the locking mechanism ensures stable working state.

[0062] After synthesis, the top hammers retract, leaving the medium temporarily in the center of the cavity. To make room for subsequent cleaning and inspection, the pyrophyllite medium needs to be ejected. The second telescopic components 306 of the three horizontally positioned top-pressing units 1 retract, pulling the cleaning assembly 5 back via the force transmission spring 504. Subsequently, a pre-set second telescopic component 306 pushes the cleaning assembly 5 forward as a whole via the force transmission spring 504, and the rotating cover 502 ejects the synthesized pyrophyllite medium from the center of the six top hammers. This automatically completes the ejection of the synthesized medium, providing operating space for subsequent top hammer cleaning and inspection.

[0063] After diamond synthesis, impurities such as graphite and pyrophyllite may remain on the surface of the test hammer. If not cleaned, these impurities will absorb or interfere with the sound waves of subsequent impact testing, leading to inaccurate results. Furthermore, these residual impurities can contaminate the raw materials during the next synthesis process, and may even damage the test hammer due to localized stress concentration caused by high pressure. Therefore, cleaning is essential before testing.

[0064] The specific working principle is as follows: The rotating motor 501 starts, driving the rotating cover 502 to rotate in both directions. The nozzles on the rotating cover 502 are connected to the air supply line, continuously spraying high-pressure gas to blow away floating dust and loose impurities on the surface of the top hammer. Simultaneously, the elastic section of the cleaning rod 505 sweeps across the various inclined surfaces of the top hammer as it rotates, scraping away any loosely attached residue.

[0065] During the cleaning process, a pressure sensor between the fixed and elastic sections of the cleaning rod 505 monitors the contact pressure in real time. When the pressure value does not exceed the preset threshold P1, it indicates that the surface of the top hammer has been basically cleaned and the next stage can begin.

[0066] If the pressure sensor detects that the pressure value exceeds the threshold P1, it indicates that there are stubborn impurities on the inclined surface of the top hammer. At this time, the striking part 4 is activated simultaneously, and the striking head 4021 of the telescopic column 402 repeatedly strikes the top hammer. The mechanical vibration generated loosens the stubborn residue. Combined with air jet and scraping, multiple cleaning processes of "vibration + blowing + scraping" are achieved until the pressure value drops below the threshold.

[0067] During the cleaning process, the top hammers of the two top pressing units 1 are also aligned with the rotating cover 502 under the control of the hydraulic cylinder, and the elastic section of the cleaning rod 505 is pressed against the inclined surface of the top hammer, and the scraping and blowing are performed synchronously with the rotation of the cleaning rod 505.

[0068] The cleaning effect is quantitatively judged by pressure sensors to ensure thorough cleaning; the combination of multiple cleaning methods greatly improves the efficiency of removing stubborn impurities; and reduces the detection misjudgment rate and the risk of damage to the top hammer caused by impurity residue.

[0069] After the top hammer is cleaned, the tapping test begins. Traditional manual tapping and listening relies on personal experience and is inefficient; the inconsistent tapping location can easily lead to inaccurate test results.

[0070] The specific working principle is as follows: When the inner frame 302 is in a horizontally locked state and cleaning is completed, the second telescopic component 306 starts to work. At this time, the second locking mechanism is in an unlocked state.

[0071] The second telescopic member 306 extends out, and the second push plate 3061 at its end moves forward, first contacting the curved end of the telescopic column 402 located inside the inner frame 302.

[0072] As the second push plate 3061 continues to move forward, it compresses the curved surface, causing the telescopic column 402 to extend outward against the elastic force of the return spring 4011 until the striking head 4021 contacts the top hammer.

[0073] The second telescopic component 306 retracts, and the telescopic column 402 springs back into the inner frame 302 under the action of the return spring 4011. Through the reciprocating motion of the second telescopic component 306, the telescopic column 402 is pushed to repeatedly strike the top hammer.

[0074] At the moment the striking head 4021 strikes the top hammer, a sound detector (such as a high-sensitivity microphone) set on the extension tube 401 or the outer frame 301 collects the striking sound wave.

[0075] The collected audio is analyzed using a voiceprint recognition algorithm to determine whether the hammer has internal cracks (dull tone) or is loose (noise). This can be combined with manual verification to achieve a closed-loop detection process of "algorithm initial judgment + manual confirmation".

[0076] As an optional solution, the second locking mechanisms located on both sides of the outer frame 301 can be controlled separately. When one side is struck, the telescopic column 402 on the other side can remain locked and retracted to prevent the striking sounds from interfering with each other and ensure the purity of the audio acquisition.

[0077] It automates tapping detection, ensuring consistent tapping positions; voiceprint algorithms improve objectivity and accuracy; and dual-sided independent control avoids signal interference.

[0078] The hammer used for synthesizing large-size diamonds is enormous, and a single cleaning rod 505 or striking point may not be able to cover the entire surface of the hammer. Therefore, the inspection mechanism 2 is improved as follows: The specific working principle is as follows: When different sizes of top hammers are needed, the second telescopic component 306 first sends the cleaning assembly 5 to the predetermined position. Then, the electromagnetic pin on the mounting plate 503 extends and inserts into the corresponding locking hole in the inner slide rail of the inner frame 302, locking the entire cleaning assembly 5 in this horizontal position. After locking, the extension and retraction of the second telescopic component 306 no longer drives the cleaning assembly 5 to move as a whole; only the telescopic column 402 is driven by the second push plate 3061 to strike. The cleaning assembly 5 then performs fixed-point rotation cleaning under the drive of the rotating motor 501.

[0079] When a single top hammer is too large and a single cleaning component 5 cannot completely cover it, two adjacent detection mechanisms 2 are activated. For example, the left detection mechanism 2 is responsible for cleaning the left half of the top hammer, and the right detection mechanism 2 is responsible for cleaning the right half. Simultaneously, different areas of the top hammer are cleaned and tapped for detection without interference, achieving complete coverage. Multi-level locking and position adjustment ensure compatibility with top hammers of different sizes; the coordinated operation of multiple detection mechanisms 2 significantly reduces the total cleaning and detection time for large top hammers; functional decoupling makes the control logic clearer and the actions more precise and reliable.
