Description

Technical Field

[0001] The present invention relates to a degreasing device for crankshaft processing, in particular to a surface degreasing device for surface processing of a crankshaft applied to the field of crankshaft processing. Background Art

[0002] When the crankshaft is processed, residual grease will hinder the contact between the quenching liquid, nitriding agent or coating and the metal surface, resulting in uneven heat treatment hardness and decreased coating adhesion. It will also cover up defects such as cracks. In addition, the remaining grease mixed into the engine lubricating oil circuit may block the filter or accelerate the deterioration of the engine oil. Therefore, surface degreasing operation is required after processing.

[0003] The specification of Chinese invention patent CN118080448B discloses a crankshaft cleaning machine. By using the traction track arranged inside the equipment shell as the power source for the rotation of the crankshaft and adjusting the injection pressure of the cleaning liquid sprayed onto the surface of the crankshaft, with a simple structural design, the stability of the whole system is improved and the cost is reduced on the premise of ensuring the cleaning effect.

[0004] The specification of Chinese invention patent CN113522874B discloses a surface cleaning machine for a crankshaft of an electric vehicle part after machining, which realizes efficient cleaning operations by using a support unit, a clamping unit and a brushing unit.

[0005] When the existing crankshaft cleaning devices clean the surface, they usually use clamping devices and self-propelled devices to achieve automated cleaning operations. However, in the actual processing process, the degree of oil fouling consolidation on the surface of the crankshaft varies. A large amount of flushing will cause waste of the flushing liquid. In addition, in order to achieve the purpose of degreasing, the cleaning liquid usually contains surfactants. After a single flushing operation, the filtered cleaning liquid can often be reused. However, the oil fouling blocks washed down are immersed in the flushing liquid stored for filtering and recycling. During the continuous dissolution process, it will consume the surfactants in the flushing liquid, resulting in poor quality of the flushing liquid during recycling. Summary of the Invention

[0006] Aiming at the above-mentioned prior art, the technical problems to be solved by the present invention are how to reduce the consumption of the cleaning liquid when cleaning the oil fouling blocks with a relatively high degree of consolidation on the surface of the crankshaft, and further reduce the content of effective surfactants in the cleaning liquid to be recycled after flushing.

[0007] To solve the above problems, the present invention provides a surface degreasing device for crankshaft surface machining, including a rinsing rack for rinsing and degreasing the crankshaft. The inner top wall of the rinsing rack is sequentially installed with a spectral component, a laser component, a cleaning component, a drying component, and a detection component. Among them, the spectral component is used to detect the degree of consolidation of grease on the crankshaft surface, the laser component is used to set micropores in the grease area where the consolidation degree exceeds the set threshold for cracking operation, the cleaning component is used to rinse the grease area on the crankshaft surface, the drying component is used to air-dry the surface of the rinsed crankshaft, and the detection component is used to detect whether there are hidden injuries on the surface of the dried crankshaft;

[0008] An action component and a clamping component are installed inside the rinsing rack. The action component is used to drive the clamping component holding the crankshaft to move linearly inside the rinsing rack;

[0009] A separation component is installed inside the rinsing rack and is located below the clamping component. The separation component includes a conveyor belt, and a number of separation units are installed on the surface of the conveyor belt. Each separation unit includes two vertical shaft plates. A closed shield and an arc-shaped filter cover are rotatably connected to the surfaces of the two vertical shaft plates. Among them, a fixed rod is installed through the inside of the arc-shaped filter cover. The surface of the fixed rod extending out of the arc-shaped filter cover is rotatably sleeved with a movable ring, and the surface of the movable ring is fixedly connected to the closed shield. The inner diameter of the closed shield is larger than the outer diameter of the arc-shaped filter cover, and the arc lengths of both the closed shield and the arc-shaped filter cover exceed half of the circumference.

[0010] In the above surface degreasing device for crankshaft surface machining, through spectral detection and laser cracking technology, stubborn oil stain blocks are effectively decomposed. The dynamic interception and separation design is adopted to reduce the consumption of surfactants, thereby indirectly reducing the consumption of cleaning liquid. While improving the cleaning efficiency, resource conservation and process reliability are taken into account.

[0011] As a further improvement of the present application, a driving motor is installed on the surface of one of the vertical shaft plates in each separation unit, and the output end of the driving motor is connected to the end of the movable ring. The end of the fixed rod is fixedly connected to the surface of the vertical shaft plate.

[0012] As a further improvement of the present application, the action component includes a guide rail component. A conveyor belt and a slide rail located outside the conveyor belt are connected to the surface of the guide rail component. A through drainage pipe is provided inside the slide rail. A storage pool is arranged below the rinsing rack, and the tail end of the drainage pipe is inside the storage pool.

[0013] As a further improvement of the present application, the separation component is installed at a position close to the laser component of the cleaning component, and the cross-sectional width of the separation component in the vertical direction is smaller than the cross-sectional width of the cleaning component in the vertical direction. A guide roller is installed inside the conveyor belt, and both sides of the guide roller are rotatably installed through a horizontal plate installed on the surface of the guide rail member. A discharge frame is provided through the area inside the washing rack corresponding to the separation component, and the discharge frame is arranged tilted downward.

[0014] As a further improvement of the present application, the clamping assembly includes a vertical plate installed on the surface of the conveyor belt, and the bottom of the vertical plate is slidably connected to the slide rail, a driving motor and a lifting plate are installed on the surface of the vertical plate, the output end of the driving motor is connected to the clamping assembly through a telescopic sleeve, the clamping assembly includes a movable plate connected to the telescopic sleeve, the top of the lifting plate is slidably connected to the hydraulic cylinder, the output end of the hydraulic cylinder is connected to the movable plate, a plurality of No. 1 frame members are connected to the surface of the movable plate close to the hydraulic cylinder, the tail end of the No. 1 frame member is rotatably connected to the swing plate through an axis rod, the tail end of the swing plate is connected to the No. 2 frame member through a axis rod, and the bottom of the surface of the No. 2 frame member is connected to a sliding block, and the sliding block is slidably connected to the surface of the hydraulic cylinder away from the movable plate, and an L-shaped block is installed at the bottom of the sliding block.

[0015] As a further improvement of the present application, an isolation plate is fixed to the inner wall of the arc-shaped filter cover, magnetic baffles are movably installed on both ends of the bottom of the isolation plate through shafts, and an electromagnetic plate is installed on the surface of the isolation plate.

[0016] As a further improvement of the present application, the tail end of the magnetic baffle in the vertical direction is in contact with the inner surface of the arc filter cover, and the length of the electromagnetic plate is smaller than the distance between the isolation plate and the bottom of the arc filter cover.

[0017] As another improvement of the present application, a small electric extension rod is installed inside the arc-shaped filter cover, and the tail end of the small electric extension rod is connected to the top of the isolation plate. The isolation plate and the inner wall of the arc-shaped filter cover are slidably connected, and the fixed end of the small electric extension rod passes through the interior of the fixed rod.

[0018] In summary, through spectral detection and laser pyrolysis technology, precise treatment is carried out on oil stains with different degrees of consolidation, effectively decomposing stubborn oil stain blocks. During the cleaning process, a dynamic interception and separation design is adopted, and a rotatable interception filter cover and a closed protective cover are used to achieve rapid separation of oil stain blocks from the cleaning liquid, reducing the secondary effect of surfactants on the intercepted oil stains, thereby reducing the consumption of the cleaning liquid. Through the cooperation of the isolation plate, electromagnetic plate and magnetic moving baffle, contact between the collected oil stain blocks and the subsequent cleaning liquid is avoided, ensuring the interception efficiency. The integration of the drying and detection modules realizes the instant air drying and hidden damage detection of the crankshaft after cleaning, forming a complete automated processing flow. The separation component cooperates with an adjustable isolation plate and a magnetic moving baffle to optimize the discharge effect of oil stain blocks and reduce residues, enabling the overall solution to improve the cleaning efficiency while taking into account resource conservation and process reliability, and is applicable to the surface treatment scenario of high-precision crankshafts.

[0031] The following describes two implementation manners of the present application in detail with reference to the accompanying drawings.

[0032] The first implementation manner:

[0033] Figures 1 - 2 A surface degreasing device for crankshaft surface machining is shown, including a flushing rack for flushing and degreasing the crankshaft. The inner top wall of the flushing rack is successively installed with a spectral component 100, a laser component 200, a cleaning component 300, a drying component 400 and a detection component 500. The spectral component 100 is used to detect the degree of consolidation of the grease on the crankshaft surface. The laser component 200 is used to set micropores in the grease area where the consolidation degree exceeds the set threshold for cracking operation. The cleaning component 300 is used to flush the grease area on the crankshaft surface. The drying component 400 is used to air-dry the surface of the cleaned crankshaft. The detection component 500 is used to detect whether there are hidden injuries on the surface of the dried crankshaft;

[0034] A movement component 600 and a clamping component 700 are installed inside the flushing rack. The movement component 600 is used to drive the clamping component 700 holding the crankshaft to move linearly inside the flushing rack;

[0035] Figures 5 - 6 It is shown that a separation component 900 is installed inside the flushing rack below the clamping component 700. The separation component 900 includes a conveyor belt. A number of separation units are installed on the surface of the conveyor belt. Each separation unit includes two vertical shaft plates. A closed shield 902 and an arc-shaped filter cover 901 are rotatably connected to the surfaces of the two vertical shaft plates. A fixed rod 905 is installed through the inside of the arc-shaped filter cover 901. The fixed rod 905 extends out of the surface of the arc-shaped filter cover 901 and is rotatably sleeved with a movable ring 903. The surface of the movable ring 903 is fixedly connected to the closed shield 902. The inner diameter of the closed shield 902 is larger than the outer diameter of the arc-shaped filter cover 901, and the arc lengths of both the closed shield 902 and the arc-shaped filter cover 901 exceed half of the circumference.

[0036] One of the vertical shaft plates in each separation unit is mounted with a driving motor 904 on its surface, and the output end of the driving motor 904 is connected to the end of the movable ring 903. The end of the fixed rod 905 is fixedly connected to the surface of the vertical shaft plate.

[0037] Specifically, when cleaning the crankshaft, after clamping the crankshaft with the clamping assembly 700, the action assembly 600 drives it to automatically walk in the flushing rack, and it passes through the spectral assembly 100, the laser assembly 200, the cleaning assembly 300, the drying assembly 400, and the detection assembly 500 in sequence. Among them, the spectral assembly 100 (which can be completed by a hyperspectral camera and is a prior art) scans and analyzes the oil stain condition on the surface of the crankshaft, and then marks the relatively solidified areas (marking can be carried out when the solidification degree exceeds 70% or the thickness ≥ 200 μm, and it can also be adjusted according to the actual situation), and transmits them to the laser assembly 200. The laser assembly 200 performs laser operations on the marked areas (a fiber laser can be used, and the laser assembly is controlled with a power of 20 - 100 W, a pulse frequency of 20 - 50 kHz, and an energy density of 2 - 10 J / cm²), so that the surface of the oil stain blocks with a higher solidification degree forms a cracked state. Then it moves to the cleaning assembly 300 (using a spray head, and the spray head is connected to a water pipe for supplying cleaning liquid, and the cleaning liquid contains surfactants for removing oil). After preliminary flushing, the cracked oil stain blocks are flushed to the separation assembly 900, and then the flushing operation continues. The flushing operation enters the working area of the drying assembly 400 for air drying treatment. Then, the detection assembly 500 (that is, an ultrasonic flaw detection structure for crack detection) is used to detect cracks on the surface of the crankshaft.

[0038] In this embodiment, the gap between two adjacent separation units is relatively small to reduce the possibility of the flushed oil stain blocks falling on the surface of the conveyor belt. For the convenience of viewing in the drawings, the interval is increased;

[0039] After the flushed oil stain blocks fall into the arc-shaped filter cover 901, the driving motor 904 drives the closed shield 902 to rotate, so that the closed shield 902 rotates above the arc-shaped filter cover 901, playing a role in blocking the passage of the subsequent cleaning liquid. At this time, in the mixture of the oil stain blocks and the cleaning liquid located inside the arc-shaped filter cover 901, the oil stain blocks are intercepted, and the cleaning liquid flows away naturally, realizing the rapid interception of the oil stain blocks. Then, the closed shield 902 continues to rotate, making the arc-shaped filter cover 901 open, and continues to receive the oil stain blocks. Then the closed shield 902 is blocked until it moves near the discharge frame 800. The oil stain blocks inside the arc-shaped filter cover 901 are transferred to the surface of the discharge frame 800 through an inclined operation and discharged through the discharge frame 800.

[0040] The action component 600 includes a guide rail part, the surface of which is connected to a conveyor belt and a slide rail 601 located outside the conveyor belt, and a drainage pipe is provided inside the slide rail 601. A storage pool is arranged under the flushing rack, and the tail end of the drainage pipe is on the inner side of the storage pool. A filter net is installed inside the storage pool to filter tiny oil particles.

[0041] Specifically, the design of the slide rail 601 allows the vertical plate equipped with the clamping assembly 700 to move along the surface of the conveyor belt, thereby realizing automated guiding operation, and the design of the drainage pipe therein can transfer the cleaning liquid entering the slide rail 601 to the storage pool.

[0042] Figure 4 It is shown that the separation component 900 is installed at a position of the cleaning component 300 close to the laser component 200, and the cross-sectional width value of the separation component 900 in the vertical direction is smaller than the cross-sectional width value of the cleaning component 300 in the vertical direction. Guide rollers are installed inside the conveyor belt, and the two sides of the guide rollers are rotatably installed through transverse plates installed on the surface of the guide rail parts. A discharge frame 800 is provided through the area inside the washing rack corresponding to the separation component 900, and the discharge frame 800 is arranged tilted downward.

[0043] Specifically, the separation component 900 is located in the initial area where the crankshaft is flushed. Therefore, the oil blocks after the laser cracking operation can quickly fall to the surface of the separation component 900 after a short flush. Subsequently, after isolation treatment by the separation unit, the contact time between the oil blocks and the cleaning fluid during the flushing process can be reduced, thereby reducing the decomposition of the oil components by the surfactant molecules in the cleaning fluid, and further reducing the consumption of the degreasing components in the cleaning fluid, so that the degreasing effect of the cleaning fluid that is subsequently recycled will not be greatly affected, thereby reducing the waste of the cleaning fluid.

[0044] Figure 3 It is shown that the clamping assembly 700 includes a vertical plate installed on the surface of the conveyor belt, and the bottom of the vertical plate is slidably connected to the slide rail 601, and a driving motor 603 and a lifting plate 602 are installed on the surface of the vertical plate. The output end of the driving motor 603 is connected to the clamping assembly 700 through a telescopic sleeve 604. The clamping assembly 700 includes a movable plate 702 connected to the telescopic sleeve 604, and the top of the lifting plate 602 is slidably connected to the hydraulic cylinder 701, and the output end of the hydraulic cylinder 701 is connected to the movable plate 702. A plurality of No. 1 frame members 703 are connected to the surface of the movable plate 702 close to the hydraulic cylinder 701. The tail end of the No. 1 frame member 703 is rotatably connected to the swing plate 704 through an axis rod, and the tail end of the swing plate 704 is connected to the No. 2 frame member 705 through a axis rod, and the bottom of the surface of the No. 2 frame member 705 is connected to a sliding block, and the sliding block is slidably connected to the surface of the side of the hydraulic cylinder 701 away from the movable plate 702, and an L-shaped block is installed at the bottom of the sliding block.

[0045] Specifically, when clamping the crankshaft, place the end of the crankshaft in the middle of the two clamping components 700, so that the end of the crankshaft is within the effective clamping area of the L-shaped block. Then start the hydraulic cylinder 701. The hydraulic cylinder 701 extends, driving the movable plate 702 in the direction close to the driving motor 603. At this time, the first frame member 703 moves synchronously, driving the swing plate 704 to tilt, and then driving the second frame member 705 to move, driving the L-shaped block to move closer to the center of the hydraulic cylinder 701, forming a clamping effect.

[0046] The function of the telescopic sleeve 604 is mainly to provide a moving space for the hydraulic cylinder 701 to drive the clamping. The crankshaft component clamped by the clamping component 700 can be driven by the driving motor 603 to rotate in the flushing rack, so as to realize a comprehensive cleaning operation.

[0047] Figure 7 As shown, a partition plate 906 is fixed to the inner wall of the arc-shaped filter cover 901. The two ends of the bottom of the partition plate 906 are movably installed with magnetic moving baffles through shaft members, and an electromagnetic plate 907 is installed on the surface of the partition plate 906.

[0048] The end of the magnetic moving baffle in the vertical state is in contact with the inner surface of the arc-shaped filter cover 901, and the length value of the electromagnetic plate 907 is less than the distance value between the partition plate 906 and the bottom of the arc-shaped filter cover 901.

[0049] Specifically, during the process of the first round of the arc-shaped filter cover 901 intercepting the oil stain blocks and the second round of the arc-shaped filter cover 901 intercepting the oil stain blocks, when the second flushing and intercepting occurs, the cleaning liquid will come into contact with the oil stain blocks intercepted by the first round of the arc-shaped filter cover 901, causing the oil stain blocks to be rinsed a second time. On the one hand, the oil stain blocks will be dissolved, and on the other hand, unnecessary surfactants will be consumed. Therefore, it needs to be improved.

[0050] After the first round of the arc-shaped filter cover 901 intercepts the oil stain blocks, at this time, the closed shield 902 blocks above the arc-shaped filter cover 901. After the solid-liquid separation is completed, the electromagnetic plate 907 is started, causing the magnetic moving baffle to move inward, so that the oil stain blocks intercepted outside the magnetic moving baffle can enter below the partition plate 906. Then the electromagnetic plate 907 switches its working state, causing the magnetic moving baffle to move outward. When it moves to the vertical state, due to the length limitation, the magnetic moving baffle maintains its current state, preventing the cleaning liquid from dissolving the oil stain blocks intercepted by the first round of the arc-shaped filter cover 901 a second time when the second round of the arc-shaped filter cover 901 intercepts the oil stain blocks.

[0051] During subsequent discharging, the electromagnetic plate 907 is restored to the attracting state, and the formed notch allows the intercepted oil stain blocks to be discharged (as Figure 8 shown).

[0052] The second implementation method:

[0053] Figure 9 It is shown that a small electric telescopic rod 908 is installed inside the arc-shaped filter cover 901, and the tail end of the small electric telescopic rod 908 is connected to the top of the isolation plate 906. The isolation plate 906 is slidably connected to the inner wall of the arc-shaped filter cover 901, and the fixed end of the small electric telescopic rod 908 penetrates through the inside of the fixed rod 905.

[0054] Different from the first embodiment, in this embodiment, when discharging materials in the first embodiment, due to the folding of the electromagnetic plate 907 and the angle formed by the magnetic moving baffle and the isolation plate 906, the problem that there is residue when the oil stain block is discharged is improved.

[0055] When discharging materials in this embodiment, different from the first embodiment, at this time, it is necessary to use the small electric telescopic rod 908 to lift the isolation plate 906. At this time, the electromagnetic plate 907 remains in the closed state. After lifting the isolation plate 906, the electromagnetic plate 907 is turned on to generate an attractive effect with the magnetic moving baffle, so that the magnetic moving baffle moves inward, so that there is a large gap between the oil stain block intercepted in the lower arc-shaped filter cover 901 and the isolation plate 906. After that, when discharging materials, the residue of the oil stain block can be reduced (as Figure 10 shown).

[0056] During the subsequent process of the small electric telescopic rod 908 driving the isolation plate 906 to descend, at this time, the magnetic moving baffle still remains in the inwardly inclined state when moving inward. When the isolation plate 906 moves to the initial position, the electromagnetic plate 907 starts to generate a repulsive effect with the magnetic moving baffle, so that the magnetic moving baffle gradually moves outward and is intercepted by the inner wall of the arc-shaped filter cover 901 when moving to the vertical state, forming a stable contact state.

[0057] Combined with the current actual needs, the above-mentioned embodiment adopted in this application, the protection scope is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
