Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of magnetic particle inspection technology for parts, and more specifically, to a portable magnetic particle inspection platform for pin components of amusement facilities. Background Technology

[0002] In the safe operation and maintenance of amusement facilities, the pin shaft is a key load-bearing and connecting component. Whether there are defects such as cracks and inclusions on its surface and near surface is directly related to the safety of facility operation. Therefore, it is necessary to conduct quality inspections regularly through magnetic particle testing.

[0003] Currently, magnetic particle inspection of pin components in amusement rides mainly relies on traditional handheld magnetic particle detectors. During inspection, operators must hold the detector and continuously move it around key areas such as the outer circular surface, end face, and transition fillets of the pin component. At the same time, they must manually control the contact between the detector and the component surface, the moving speed, and the inspection angle to ensure comprehensive defect detection.

[0004] However, this inspection method has significant limitations. On the one hand, most pins are cylindrical, with some models being quite long and tens of centimeters in diameter. Operators need to keep the detector moving steadily throughout the process, which is not only labor-intensive and prone to causing operator fatigue, but may also lead to blind spots due to hand tremors, affecting the accuracy of the inspection. On the other hand, the complete inspection of a single pin requires multiple adjustments to the position and attitude of the detector, and each inspection usually takes a long time. For amusement facilities containing dozens to hundreds of pins, the overall inspection efficiency is extremely low, making it difficult to meet the requirements of operation and maintenance for inspection cycles. Furthermore, the continuous manual operation mode further restricts the improvement of inspection efficiency and cannot adapt to the needs of large-scale and efficient safety inspection of amusement facilities. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a portable magnetic particle inspection platform for amusement ride pin parts, which solves the technical problem of low efficiency in magnetic particle inspection of amusement ride pin parts in the prior art.

The two side walls have corresponding positioning notches, and the positioning notches of the cleaning fluid tank are used to position the pin. A cleaning brush is provided inside the cleaning fluid tank, and the outer peripheral surface of the cleaning brush is used to attach to and clean the pin shaft.

[0025] like Figures 1-4 The diagram illustrates a portable magnetic particle inspection platform for amusement ride pin components according to an embodiment of this disclosure. The platform includes a substrate 100, a V-groove 200, a pusher assembly 300, a rotation drive assembly 400, a magnetic particle inspection assembly 500, and a contrast enhancer nozzle 600. The V-groove 200 is disposed in the substrate 100 and has an inlet end and an outlet end. The pusher assembly 300 is disposed above the V-groove 200 and is used to push the pin along the V-groove 200 from the inlet end to the outlet end. The rotation drive assembly 400 is disposed on the V-groove 200 and is used to drive the pin in the V-groove 200 to rotate. The magnetic particle inspection assembly 500 is disposed near the outlet end of the V-groove 200 and is used to inspect the pin. The pin moves out of the V-groove 200 from the outlet end. The contrast enhancer nozzle 600 is disposed between the magnetic particle inspection assembly 500 and the V-groove 200 and is used to spray contrast enhancer onto the pin.

[0026] For example, the base 100 is easy to transport and ensures the stability of the platform structure. The four corners of the bottom are equipped with casters with brakes, which makes it easy for the platform to move flexibly in different places and can be fixed in position by braking.

[0027] The substrate is used to fix the V-groove 200, the feeding assembly 300, the rotation drive assembly 400, the magnetic particle inspection assembly 500, and the contrast enhancer nozzle 600.

[0028] The V-groove 200 consists of two inclined planes at a 90° angle. This angle design allows for better adaptation of cylindrical pin parts, ensuring their stable placement within the V-groove. The V-groove has a certain length to accommodate longer pins. It connects to the mounting frame inside the base and is fixed to the support, ensuring a secure installation and preventing movement during flaw detection.

[0029] The pusher assembly 300 can push the pin to move within the V-groove, covering part of the pin's circumference to ensure stability during the pushing process. The rotation drive assembly 400 can contact the pin surface within the V-groove, driving the pin to rotate.

[0030] The magnetic particle inspection kit 500 can effectively detect cracks, inclusions, and other defects on and near the surface of pins. The magnetic yoke of the inspector adopts a U-shaped structure. The magnetic particle inspector is connected to the internal mounting frame of the substrate via an adjustable mounting arm. The mounting arm has multiple adjustable joints, allowing for horizontal and vertical movement of the inspector and adjustment of the inspection angle. The distance between the inspector and the V-groove can be adjusted according to actual inspection requirements, ensuring accurate inspection of the pin.

[0031] The contrast enhancer nozzle 600 uses a fan-shaped nozzle, which can uniformly spray the contrast enhancer onto the pin surface, making the flaw detection results clearer. The nozzle is connected to the supply pipe, and the supply system includes a storage tank, a peristaltic pump, and a flow control valve. The storage tank is made of transparent plastic, has a certain capacity, and allows for easy observation of the remaining contrast enhancer, enabling precise control of the spraying flow rate according to actual needs. The flow control valve is installed on the supply pipe to adjust the supply speed and ensure the spraying effect. The supply system is mounted inside the substrate via a mounting bracket and connected to the internal mounting frame of the substrate.

[0032] Place the pin to be inspected in the V-groove 200. Adjust the magnetic pole spacing of the magnetic particle inspection assembly 500 and the position and angle of the mounting arm according to the pin's diameter. Simultaneously adjust the rotation drive assembly 400 to ensure good contact between the rotation drive assembly 400 and the pin surface. Set the spray flow rate of the contrast enhancer nozzle 600 using the flow regulating valve according to actual requirements.

[0033] Start the peristaltic pump, and the contrast enhancer is evenly sprayed from the reservoir through the supply pipe onto the pin surface via a fan-shaped nozzle. The contrast enhancer forms a uniform thin film on the pin surface, increasing the contrast between the magnetic powder and the pin surface, making flaw detection defects clearer.

[0034] The motor of the rotation drive assembly 400 is started, driving the pin to rotate within the V-groove. Simultaneously, the pusher assembly 300 pushes the pusher plate, causing the pin to move slowly along the V-groove. During the rotation and movement of the pin, the flaw detector of the magnetic particle inspection assembly 500 performs comprehensive flaw detection on the surface and near-surface of the pin. The magnetic field generated by the flaw detector causes leakage magnetic fields at defects on the surface and near-surface of the pin. Magnetic powder accumulates under the influence of the leakage magnetic field, thus revealing the location, shape, and size of the defects.

[0035] Once the pin has moved along the V-groove to the other end and completed one full flaw detection cycle, stop rotating the drive assembly and the pusher assembly. Observe and record the flaw detection results, then remove the pin from the V-groove to complete the flaw detection.

[0036] The movement and rotation of the pin are automatically completed by the pusher assembly 300 and the rotation drive assembly 400. Operators do not need to manually push and rotate the pin, which greatly reduces labor intensity, reduces operator fatigue, and improves the comfort of flaw detection operations.

[0037] The rotation drive assembly 400 can drive the pin shaft to rotate stably, and the pusher assembly 300 ensures that the pin shaft moves at a uniform speed, avoiding hand tremors and blind spots that may occur during manual operation. This allows the magnetic particle inspection assembly 500 to inspect the pin shaft more accurately and improves the accuracy of the inspection results.

[0038] This platform automates the inspection of pins, significantly reducing the time required for a single inspection. For amusement rides with multiple pins, the overall inspection efficiency is significantly improved, meeting the inspection cycle requirements of maintenance operations and adapting to the large-scale, high-efficiency safety inspection needs of amusement rides. Through adjustments, the platform can accommodate pins of different diameters and lengths, demonstrating strong versatility and applicability.

[0039] In some examples, such as Figure 1 , Figure 4 As shown, the pusher assembly 300 includes a movable pusher plate 310, a lead screw 320, and a first motor 330. The movable pusher plate 310 is slidably disposed above the V-groove 200 and is configured to push the pin axis from one side to move toward the magnetic particle inspection assembly 500. The lead screw 320 is threadedly connected to the movable pusher plate 310 and is used to drive the movable pusher plate 310 to move between the inlet end and the outlet end. The first motor 330 is connected to the lead screw 320 and is used to drive the lead screw 320 to rotate.

[0040] For example, the push plate is rectangular in shape, and linear sliders are installed on both sides of the movable push plate 310. Inside the base 100, corresponding to the positions of the linear sliders, two parallel linear guide rails are installed. The movable push plate 310 can slide smoothly along the linear guide rails, ensuring that there is no deviation or jamming during the pushing of the pin.

[0041] The lead screw 320 is a high-precision ball screw. The lead screw 320 and the movable push plate 310 are connected by a screw nut. When the lead screw rotates, it can reliably drive the movable push plate 310 to move along the linear guide. The first motor 330 can provide sufficient power to drive the lead screw 320 to rotate, thereby pushing the movable push plate 310 and the pin shaft to move.

[0042] When flaw detection of the pin is required, the operator starts the first motor 330. Driven by the driver, the first motor 330 begins to rotate at a preset speed and angle. This drives the lead screw 320 to rotate. Since the lead screw 320 is threadedly connected to the movable push plate 310 via a lead screw nut, and the movable push plate 310 engages with the linear guide rail inside the base 100 via a linear slider, the rotation of the lead screw is converted into linear movement of the movable push plate 310 along the linear guide rail. The movable push plate 310 pushes the pin placed in the V-groove 200 from one side at a smooth speed, moving it towards the magnetic particle inspection assembly 500.

[0043] While the pusher assembly moves the pin, the rotation drive assembly 400 drives the pin to rotate synchronously, ensuring that the pin surface passes through the detection area of ​​the magnetic particle inspection assembly 500 in all directions during the movement. Simultaneously, the contrast enhancer nozzle 600 evenly sprays contrast enhancer onto the pin surface before the pin moves, enhancing the flaw detection display effect. Through the coordinated operation of the pusher assembly, rotation drive assembly, magnetic particle inspection assembly, and contrast enhancer nozzle, efficient and accurate flaw detection of the pin is achieved.

[0044] In some examples, such as Figure 1 , Figure 2 As shown, the rotation drive assembly 400 includes several drive wheel sets, which are arranged sequentially along the length of the V-groove 200. Each drive wheel set includes a first support wheel 411 and a second support wheel 412 that are axially parallel to the length of the V-groove 200.

[0045] The rotation drive assembly 400 further includes a first drive shaft 421, a second drive shaft 422, an idler gear 430, and a second motor 440. The first drive shaft 421 is connected to the first support wheel 411 of each drive wheel assembly and is used to drive each first support wheel 411 to rotate synchronously. The second drive shaft 422 is connected to the second support wheel 412 of each drive wheel assembly and is used to drive each second support wheel 412 to rotate synchronously. The first drive shaft 421 and the second drive shaft 422 are connected by the idler gear 430, so that the first drive shaft 421 and the second drive shaft 422 are connected by transmission and rotate in the same direction. The second motor 440 is used to drive the first drive shaft 421 or the second drive shaft 422 to rotate.

[0046] For example, the drive wheel assembly consists of multiple sets of drive wheels arranged sequentially along the length of the V-groove 200. The specific number is determined according to the length of the V-groove and the pin size to ensure stable support and drive for pins of different lengths. Each drive wheel assembly consists of two support wheels, namely the first support wheel 411 and the second support wheel 412.

[0047] Both the first support wheel 411 and the second support wheel 412 are made of high-strength rubber, which has good elasticity and friction, effectively avoiding damage to the pin surface, while ensuring sufficient friction between them to drive the pin to rotate. Their axial direction is parallel to the length direction of the V-groove 200. This design allows the support wheel to better adapt to the shape and direction of movement of the pin when driving the pin to rotate.

[0048] Each first support wheel 411 is fixed to the first drive shaft 421 by a key connection, and each second support wheel 412 is similarly fixed to the second drive shaft 422 by a key connection, ensuring that the support wheels rotate synchronously with the drive shaft. The two ends of the drive shaft are mounted on brackets inside the base 100 by bearings, so that the drive shaft rotates smoothly.

[0049] The idler gear 430 is a standard spur gear that meshes with the gears on the first drive shaft 421 and the second drive shaft 422 to achieve the transmission connection between the first drive shaft 421 and the second drive shaft 422, and to ensure that they rotate in the same direction. This design allows the two sets of support wheels to rotate synchronously and in the same direction, jointly and stably driving the pin shaft to rotate. The second motor 440 is connected to the first drive shaft 421, and can also be optionally connected to the second drive shaft 422.

[0050] When the second motor 440 starts, its rotational motion is transmitted to the first drive shaft 421. The first drive shaft 421 drives the first support wheel 411 to rotate. Simultaneously, the gear on the first drive shaft 421 meshes with the gear on the second drive shaft 422 through the idler gear 430, transmitting power to the second drive shaft 422, which in turn drives the second support wheel 412 to rotate. Due to the transmission effect of the idler gear 430, the first drive shaft 421 and the second drive shaft 422 rotate in the same direction, causing the first support wheel 411 and the second support wheel 412 in each set of drive wheels to rotate synchronously and in the same direction.

[0051] The pin, placed in the V-groove 200, contacts the first support wheel 411 and the second support wheel 412 on both sides, respectively. As the drive wheel assembly rotates, the friction between the support wheels and the pin causes the pin to rotate around its own axis within the V-groove. Multiple drive wheel assemblies are evenly distributed along the length of the V-groove, working together to ensure the stability and uniformity of the pin during rotation, providing favorable rotational conditions for the magnetic particle inspection assembly 500 to perform comprehensive and accurate flaw detection on the pin's surface.

[0052] Multiple sets of drive wheels are arranged along the length of the V-groove and work together on the pin to provide a uniform and stable driving force. This ensures that the pin will not jump or slip during rotation, providing stable testing conditions for magnetic particle testing and improving the accuracy of the testing results.

[0053] The idler gear 430 enables the transmission connection between the first drive shaft 421 and the second drive shaft 422, and they rotate in the same direction. This allows the two support wheels in each set of drive wheels to rotate synchronously, further enhancing the stability and controllability of the pin rotation and preventing damage to the pin due to asynchronous rotation of the support wheels.

[0054] The rotary drive assembly has a relatively simple structural design, employing common gear transmission and motor drive methods, making it easy to install, maintain, and repair. Furthermore, the selected motors and components offer high reliability, reducing the equipment failure rate and improving its lifespan and operating efficiency.

[0055] In some examples, such as Figure 3 As shown, the magnetic particle inspection assembly 500 includes a magnetic yoke 510 and a guide wheel 520. The magnetic yoke 510 is U-shaped and has two abutment portions 511. The two abutment portions 511 are used to abut against the outer peripheral surface pin. The guide wheel 520 is provided at each of the two abutment portions 511.

[0056] For example, the yoke 510 is made of a soft magnetic material with high permeability, which can efficiently conduct and concentrate the magnetic field, improving the sensitivity of magnetic particle testing. The yoke has an overall U-shaped structure, and the opening width is designed according to the diameter range of common pins to meet the testing requirements of pins of different specifications. Two abutment parts 511 are located at both ends of the U-shaped yoke, and their ends are designed as arcs that fit the surface of the pin. The curvature is consistent with the outer circle of common pins, which can better abut the pin and ensure that the magnetic field is evenly distributed on the pin surface.

[0057] The guide wheel 520 is installed on the abutment part 511 and can rotate flexibly. It can fit against the surface of the pin and play a guiding and buffering role in the flaw detection process. The guide wheel 520 can make good contact with the surface of the pin, which does not affect the magnetic field applied to the pin by the magnetic yoke part 510, and can play a stable guiding role in the rotation and movement of the pin.

[0058] When the magnetic particle inspection assembly 500 is operating, the two abutment portions 511 of the yoke 510 abut against the pin surface. By passing an electric current through the yoke 510, a magnetic field is generated inside the yoke 510. Due to the high permeability of the yoke 510, the magnetic field is concentrated and transmitted to the pin surface through the abutment portions 511, magnetizing the pin. If there are defects such as cracks or inclusions on or near the pin surface, leakage magnetic fields will be generated at these defects, attracting magnetic particles to accumulate, thereby revealing the location, shape, and size of the defects.

[0059] During the rotation and movement of the pin, the guide wheel 520 at the contact part 511 contacts the pin surface. The guide wheel 520 is in close contact with the pin surface, and as the pin rotates and moves, the guide wheel 520 can roll on the pin surface, playing a guiding role and ensuring that the magnetic yoke part 510 and the pin always maintain good contact, so that the magnetic field is uniformly applied to the pin surface and the accuracy of flaw detection is improved.

[0060] In some examples, such as Figure 4 As shown, it also includes a cleaning assembly 700 for cleaning the pin. The cleaning assembly 700 is used to clean the pin and includes a cleaning fluid tank 710, a cleaning brush 720, and a third motor 730. The cleaning fluid tank 710 is located at the inlet end of the V-groove 200. The two side walls of the cleaning fluid tank 710, which are perpendicular to the length of the V-groove 200, can jointly support the pin. The two side walls have corresponding positioning notches 711. The positioning notches of the cleaning fluid tank 710 are used to position the pin. The cleaning brush 720 is provided inside the cleaning fluid tank 710. The outer peripheral surface of the cleaning brush 720 is used to adhere to and clean the pin.

[0061] The cleaning brush 720 is rotatably disposed inside the cleaning fluid tank 710 and located below the positioning notch 711 for cleaning the pin shaft; the cleaning assembly 700 also includes a third motor 730, which is used to drive the cleaning brush 720 to rotate.

[0062] The cleaning fluid tank 710 is located on the side of the V-groove 200 away from the magnetic particle inspection component 500, and has a positioning notch 711 on the upper part for the pin shaft to pass through. The cleaning brush 720 is rotatably disposed in the cleaning fluid tank 710 and located below the positioning notch 711 for cleaning the pin shaft. The third motor 730 is used to drive the cleaning brush 720 to rotate.

[0063] For example, the cleaning fluid tank 710 can hold sufficient cleaning water. The upper part of the cleaning fluid tank has a positioning notch 711, which can be V-shaped, trapezoidal, semi-circular, etc. Figure 4 In the illustrated embodiment, the positioning notch 711 is a first semi-circular notch. Its radius is designed based on the diameter of a common pin to ensure the pin can pass through smoothly. The edges of the positioning notch are smoothed to prevent scratching the surface when the pin passes through. The cleaning fluid tank 710 is fixed inside the base 100, located on the side of the V-groove 200 away from the magnetic particle inspection assembly 500. A drain outlet with a valve is provided at the bottom of the cleaning fluid tank to facilitate the discharge of wastewater after cleaning.

[0064] The 720 cleaning brush consists of a brush head and a handle. The brush head is made of high-strength nylon bristles, which have excellent abrasion resistance and water resistance, and can effectively remove oil, dust and residual magnetic powder from the surface of the pin. It ensures contact with the pin, and combined with the rotation and movement of the pin, it can clean the entire outer surface of the pin.

[0065] The cleaning brush 720 is rotatably mounted inside the cleaning fluid tank 710, located below the positioning notch 711. One end of the rotating shaft of the cleaning brush extends out of the cleaning fluid tank for connection to the third motor 730. The third motor 730 is connected to the rotating shaft of the cleaning brush 720.

[0066] Before flaw detection of the pin, place the pin on the V-groove 200, with one end passing through the positioning notch 711 at the top of the cleaning fluid tank 710. Depending on the degree of contamination of the pin, inject an appropriate amount of water into the cleaning fluid tank 710; a suitable amount of cleaning agent can be added to enhance the cleaning effect. During cleaning, the water level in the cleaning fluid tank 710 must be lower than the bottom of the positioning notch 711, and the cleaning brush 720 must be partially submerged in water, with its upper end in contact with the pin. This allows the cleaning brush 720 to achieve both water rinsing at its lower end and cleaning of the pin at its upper end.

[0067] After the third motor 730 is started, it drives the cleaning brush 720 to rotate. The rotating cleaning brush 720 contacts the pin surface passing through the positioning notch 711, and the bristles clean the pin surface during rotation. Due to the elasticity and dense arrangement of the bristles, it can effectively remove oil, dust, and magnetic powder residue from the pin surface. As the pusher assembly 300 pushes the pin along the V-groove 200, and the first support wheel 411 and the second support wheel 412 drive the pin to rotate, the cleaning brush 720 continuously cleans the pin surface, achieving a thorough cleaning of the pin. When the pin has completely passed through the cleaning fluid tank 710, the third motor 730 is stopped. At this point, the pin surface has been cleaned and can be used for subsequent flaw detection operations.

[0068] In some examples, such as Figure 4 As shown, the cleaning assembly 700 also includes a seal 740, which is slidably disposed on one side of the positioning notch 711 and located inside the cleaning fluid tank 710. The seal 740 has a semi-circular notch 741, which has an arc-shaped flexible sealing portion 742 for sealingly abutting against the pin.

[0069] For example, the seal 740 is made entirely of corrosion-resistant rubber material, which has good elasticity, wear resistance and water resistance, can adapt to the humid environment inside the cleaning fluid tank and maintain its sealing performance during long-term use.

[0070] The semi-circular notch 741 on the seal 740 mates with the positioning notch 711 on the cleaning fluid tank 710, and its radius is adapted to the positioning notch 711 and the diameter of a common pin. The edge of the semi-circular notch 741 is designed with an arc-shaped flexible sealing part 742, which is made of soft rubber. When the pin passes through, the flexible sealing part 742 can tightly fit the surface of the pin to form a sealing contact, effectively preventing water in the cleaning fluid tank from leaking from the gap between the positioning notch 711 and the pin.

[0071] Two guide sliders are installed on one side of the seal 740. The inner wall of the cleaning fluid tank 710 is provided with two parallel guide grooves corresponding to the positions of the guide sliders, to ensure that the seal 740 can slide smoothly along the guide grooves and maintain the position of the seal during the sliding process.

[0072] As the pin passes through, the seal 740 slides along the guide groove on the inner wall of the cleaning fluid tank 710 under the push of the pin. Due to the elasticity of the flexible seal 742, it tightly adheres to the pin surface during the pin's passage, forming a sealing structure to prevent water in the cleaning fluid tank from flowing out through the gap between the positioning notch 711 and the pin. After the pin has completely passed through the seal 740, the seal returns to its initial position under its own elasticity and the action of a possible return spring, continuing to maintain a sealing state and preventing water leakage from the cleaning fluid tank during the cleaning process.

[0073] While the seal 740 seals the pin, the third motor 730 drives the cleaning brush 720 to rotate. The rotating cleaning brush 720 brushes the surface of the pin that passes through the seal 740 and the positioning notch 711, removing oil, dust, and other impurities to facilitate subsequent magnetic particle inspection. As the pusher assembly 300 pushes the pin along the V-groove 200, the cleaning brush 720 continuously cleans the pin, while the seal 740 maintains a seal between the pin and the cleaning fluid tank, ensuring that the cleaning process takes place in a relatively enclosed environment, improving the cleaning effect and preventing water leakage to other parts of the platform.

[0074] In some examples, such as Figure 4 As shown, the cleaning assembly 700 also includes a first elastic member 750, one end of which acts on the seal 740 and the other end of which acts on the cleaning fluid tank 710, enabling the seal 740 to slide close to the pin.

[0075] For example, a compression spring is selected as the first elastic element 750, which has good elastic recovery capability and can stably provide a force close to the pin to the seal 740. One end abuts against the seal 740, and the other end presses against the cleaning fluid tank 710. The semi-circular notch 741 is aligned with the positioning notch 711, and the flexible sealing part 742 maintains appropriate contact pressure with the pin, which can ensure the sealing effect without causing excessive resistance to the insertion of the pin.

[0076] When the pin begins to insert into the positioning notch 711 and the semi-circular notch 741, the end of the pin first contacts the flexible sealing part 742, pushing the seal 740 to overcome the spring force and causing the flexible sealing part 742 to fit against the pin surface, achieving a good seal. Throughout this process, the spring maintains a constant force on the seal 740, ensuring that the flexible sealing part 742 is in close contact with the pin surface, preventing water leakage.

[0077] In some examples, such as Figure 4 As shown, the cleaning assembly 700 also includes a second elastic member 760, which acts on the flexible sealing part 742, enabling the curvature of the flexible sealing part 742 to change and seal against pins of different diameters.

[0078] For example, the second elastic element 760 can be designed as a spring, capable of acting evenly on the flexible sealing portion 742. Inside the flexible sealing portion 742, a groove matching the width of the rubber strip is provided along its axial direction. Embedding the second elastic element 760 into this groove ensures that the rubber strip and the flexible sealing portion 742 are tightly bonded and can deform together under force.

[0079] This design allows the radius of the semicircular notch 741 to accommodate a certain range of pin diameters, so that under the action of the second elastic element 760, the flexible sealing part 742 can better seal and abut against pins of different diameters.

[0080] When pins of different diameters pass through the semi-circular notch 741 of the seal 740, the pin surface exerts radial pressure on the flexible seal 742. At this time, the second elastic element 760 embedded inside the flexible seal 742 is compressed or stretched. The second elastic element 760 changes its shape accordingly based on the diameter of the pin, thereby causing a change in the curvature of the flexible seal 742. In this way, the flexible seal 742 can tightly fit the surface of pins of different diameters, achieving a good sealing effect and preventing water leakage from the cleaning fluid tank.

[0081] In some examples, such as Figure 4 As shown, the cleaning fluid tank 710 is square and integrally formed with the V-shaped groove 200. For example, the square design of the cleaning fluid tank 710, cast integrally with the V-shaped groove 200, ensures the integrity and strength of the structure. This integrated design eliminates the connection gaps between the two, enhancing not only the stability of the equipment but also avoiding the risk of leakage due to gaps. Compared to the V-shaped tank, the square cleaning fluid tank has a larger volume and more bottom space, allowing it to hold more cleaning water. During the cleaning process, the water and cleaning agent in the cleaning fluid tank are in full contact with the pin surface in a relatively sealed environment, ensuring effective cleaning.
