Description

Technical Field

[0001] This invention relates to the field of rolling mill equipment technology, and in particular to an integrated cleaning and testing device suitable for rolling mills. Background Technology

[0002] Rolls are core process components in rolling production lines, and their surface condition and geometric accuracy directly affect the surface quality and rolling stability of the rolled material. During long-term service, rolls are prone to accumulating contaminants such as oxide scale, oil, and metal debris. Additionally, wear, thermal fatigue, and other factors can cause defects such as out-of-roundness and localized damage. Therefore, rolls typically require cleaning before and after each use, and their surface quality and key geometric parameters must be inspected.

[0003] Currently, the cleaning of rolls is mostly done manually by hand-held spray guns or by immersion in tanks. This is not only labor-intensive and inefficient, but also consumes a lot of cleaning fluid and water resources. The cleaning effect is unstable due to human factors, and the water spray during the cleaning process can also pollute the working environment. Although some automatic cleaning equipment such as spray or brush has been used, its functions are relatively simple. It usually only has the ability to clean. After the rolls are cleaned, manual visual inspection or testing with the help of special measuring tools and instruments is still required.

[0004] However, rolls require numerous inspection items, such as surface defects, roundness, straightness, radial runout, and step length. Different parameters often necessitate different inspection methods, sometimes even requiring the rolls to be transported to specialized inspection equipment. When cleaning and inspection are handled by different equipment, the rolls need to be hoisted, transported, and repositioned multiple times between machines. This not only results in long work cycles and large space requirements but also easily introduces positioning errors due to repeated clamping. Furthermore, because the roll's position before and after cleaning differs from the inspection benchmark, it is difficult to directly compare the surface condition of the roll before and after cleaning, making it difficult to objectively assess the cleaning effect. In addition, relying on manual visual inspection or sampling to inspect the surface quality of rolls is highly subjective and inconsistent, failing to meet the requirements for comprehensive, rapid, and traceable inspection of roll surface quality. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned defects and provide an integrated cleaning and testing device suitable for rolling mill rolls.

[0006] In order to overcome the defects in the background technology, the technical solution adopted by the present invention to solve its technical problem is: an integrated cleaning and testing equipment for rolling mills, including an integrated housing assembly as the integrated base of the whole machine, which is provided with a moving drive mechanism to drive the rolling mills to each station;

[0016] Two lifting wheels are arranged in parallel rolling within each of the bearing boxes. A toothed area is formed on the outer periphery of each lifting wheel. A rotating column is also rotatably arranged within the bearing box. A rotating drive gear is coaxially arranged on the rotating column. The rotating drive gear meshes with the toothed areas on the outer periphery of both lifting wheels.

[0017] The end of the rotating column is coaxially provided with a mating groove for engaging with the docking part of the clamping drive mechanism, thereby driving the roll to rotate.

[0018] Further improvements include alignment arrows on the lifting wheel and the bearing housing; an indexing arrow at the end of the rotating column; and an indexing mark centered on the central axis of the rotating column on the bearing housing.

[0019] In a further improvement, the functional box mechanism includes an outer box, a lifting and moving box, and a mixing box;

[0020] The outer casing has a cavity in its inner wall. At least four conduits communicating with the cavity are vertically connected to the upper end of the outer casing. The conduits also extend to the outside through the integrated casing assembly. The free ends of the conduits are connected to a water supply mechanism through pipelines. A spray hole communicating with the cavity is opened at a preset position on the inner wall of the outer casing.

[0021] A lifting and moving box is installed on the top of the outer casing. A limit block is installed on the section of the lifting and moving box inside the outer casing.

[0022] The upper end of the lifting moving box is connected to the output end of the lifting drive mechanism; the upper end of the lifting moving box is also provided with a lifting distance measuring component for measuring distance, which is used to detect the displacement distance of the lifting moving box.

[0023] As a further improvement, flexible bristles adapted to the outer periphery of the roller are provided on both sides of the air outlet window at the lower end of the mixing box.

[0024] In a further improvement, the visual acquisition mechanism includes a support assembly on which multiple camera modules and multiple light source modules are mounted.

[0026] The rear end of the movable plate assembly is provided with a movable column that can be inserted into the annular box. The preset interface on the annular box is connected to the gas supply mechanism through a pipeline.

[0027] The movable plate assembly is also equipped with a dimension measuring component, which is used to detect the total length of the roll and the length of the steps at both ends of the roll.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] See Figure 1 and Figure 2 This embodiment provides an integrated cleaning and testing equipment for rolling mill rolls, including an integrated housing assembly 1, which serves as the integrated base of the whole machine. Inside the housing assembly 1, a moving drive mechanism 6 is provided to drive the rolling mill rolls to each workstation to complete subsequent cleaning, drying and testing operations.

[0045] At least one set of positioning and bearing drive mechanism 5 is provided, all of which are set on the moving drive mechanism 6. It is used to roll the two ends of the bearing roll so that the rolling roll can be driven by the moving drive mechanism 6 to move along the horizontal preset trajectory, so that the rolling roll can be moved to the inspection station and the cleaning and drying station.

[0046] The lifting drive mechanism 4 is set on the integrated box assembly 1 and located directly above the preset trajectory of the horizontal movement of the roll. It is set one-to-one with the rolls that are moved directly below it and carried by the positioning and bearing drive mechanism 5, ensuring that each roll has a corresponding lifting drive mechanism 4. Its output end is connected to the functional box mechanism 3 located below it, driving the functional box mechanism 3 to move up and down, so that it moves down and covers the rolls. In the covered state, the washing and drying operations are performed, thereby improving the water utilization efficiency.

[0047] The clamping drive mechanism 7 is symmetrically arranged on both sides of the preset horizontal movement trajectory of the roll. It is installed in the integrated housing assembly 1 and is used to cooperate with the docking parts at both ends of each set of positioning and bearing drive mechanism 5 to trigger the positioning and bearing drive mechanism 5 to drive the roll to rotate. It is used for auxiliary rotation in the cleaning and drying station, as well as auxiliary rotation and roll step and length dimension detection in the detection station.

[0048] A visual acquisition mechanism 8 and multiple roundness measuring components 9 are provided on the outside of the functional box mechanism 3 and on the horizontal movement trajectory of the roll. The visual acquisition mechanism 8 is used to detect appearance defects of the roll and compare the surface state of the roll before and after cleaning. The roundness measuring components 9 are used to detect the radial runout of the roll during rotation, the radius difference of each area of ​​the roll, and the straightness of the roll on the positioning and bearing drive mechanism 5.

[0049] The equipment's workflow consists of four stages: "transfer—inspection—cleaning and drying—inspection".

[0050] Inspection process: The moving drive mechanism 6 drives the positioning and bearing drive mechanism 5 to move horizontally together with the roll, and moves the roll to the inspection station (below the vision acquisition mechanism 8).

[0051] The visual acquisition mechanism 8 first acquires an image of the surface of the roll before cleaning;

[0052] When the roll returns to the station after cleaning, the roundness measuring component 9 performs multi-point distance measurement on different positions along the axial direction of the roll. The lifting drive mechanism 4 drives the functional box mechanism 3 to move up and down, thereby moving the roundness measuring component 9 up and down. This allows for the detection of the closest point at different positions on the roll, the determination of the straightness of the roll after load, and the detection of whether the radius difference in different areas of the roll is within the tolerance range. This design can be used to detect rolls of different sizes.

[0053] The clamping drive mechanism 7 cooperates with the docking parts at both ends of the positioning and bearing drive mechanism 5 to drive the roll to rotate. The clamping drive mechanism 7 is used to detect the total length of the roll and the length of each step of the roll. At the same time, the roundness measuring component 9 detects the radial runout of the roll when it rotates.

[0054] The visual acquisition unit 8 acquires surface images of the rolls after cleaning, detects defects in the rolls' appearance, compares the images before and after acquisition, and evaluates the cleaning effect.

[0055] Cleaning and drying process: The moving drive mechanism 6 moves the roller to the cleaning and drying station (directly below the function box mechanism 3).

[0056] The lifting drive mechanism 4 drives the functional box mechanism 3 to move down and cover the roller. The clamping drive mechanism 7 cooperates with the docking parts at both ends of the positioning and bearing drive mechanism 5 to trigger the positioning and bearing drive mechanism 5 to drive the roller to rotate. The functional box mechanism 3 cleans and dries the roller, realizing simultaneous rotation and cleaning and drying.

[0057] In a specific embodiment, a detachable filter mechanism 2 is installed inside the integrated housing assembly 1 to receive the wastewater generated after cleaning. After filtering the wastewater, impurities, iron filings and other solid residues are filtered out. The filtered wastewater is collected inside the integrated housing assembly 1 for subsequent recycling. At the same time, the water mist generated during rinsing will also condense on it. This method can avoid secondary pollution from impurities and water mist affecting detection accuracy and electrical safety.

[0058] See Figure 2 In a specific embodiment, the moving drive mechanism 6 includes two parallel main tracks 605 and two drive shafts 606. Two sliding plates 603 are slidably arranged on each main track 605. At least one set of positioning and bearing drive mechanisms 5 is installed on the corresponding sliding plates 603 on the two main tracks 605. After the rolling bearing roller is rolled on the positioning and bearing drive mechanism 5, the corresponding sliding plate 603 will move synchronously, thereby driving the roller to move horizontally. Installing multiple positioning and bearing drive mechanisms 5 can realize the simultaneous parallel transfer of multiple rollers. The two sets of corresponding sliding plates 603 operate alternately: when one set performs cleaning, drying / inspection operations in the workstation, the other set completes roller disassembly and loading in the loading and unloading area, realizing the alternating cycle of "one set of operations, one set of disassembly" or "one set of installation, one set of operations", improving equipment utilization and work cycle.

[0059] Two drive shafts 606 are rotatably mounted inside the integrated housing assembly 1, and the drive shafts 606 are perpendicular to the main track 605. Two moving drive gears 602 are coaxially mounted on each drive shaft 606, and the moving drive gears 602 respectively mesh with the toothed areas opened at the lower end of the corresponding slide plate seat 603. The integrated housing assembly 1 is respectively equipped with a moving motor 601 coaxially connected to the drive shaft 606. The moving motor 601 drives the drive shaft 606 to rotate, and drives the slide plate seat 603 to move along the main track 605 through the gear transmission of the moving drive gears 602. That is, one drive shaft 606 synchronously controls two slide plates 603 (located on two main tracks 605, in a corresponding group), ensuring that the two ends of the positioning and bearing drive mechanism 5 move synchronously without deviation, and realizing the parallel and stable alternating movement of the rollers.

[0060] The slide plate seat 603 is equipped with a moving distance measuring component 604, which is used to measure and provide real-time distance feedback on the displacement of the slide plate seat 603. The moving distance measuring component 604 is used to precisely control the roller conveying distance, ensuring that the roller stops accurately at the cleaning and drying station and the inspection station.

[0061] See Figure 3 and Figure 4 In a specific embodiment, the positioning and bearing drive mechanism 5 includes two relatively distributed bearing boxes 505, which are connected by at least two connecting rods 502 to maintain the spacing and synchronize the movement.

[0062] Two lifting rollers 501 are arranged in parallel rolling within each of the bearing housings 505. A toothed area is formed on the outer periphery of each lifting roller 501. A rotating column 508 is also rotatably arranged within each bearing housing 505. A rotary drive gear 503 is coaxially mounted on the rotating column 508. The rotary drive gear 503 meshes with the toothed areas on the outer periphery of both lifting rollers 501. When the rotary drive gear 503 rotates, it drives the two lifting rollers 501 to rotate synchronously. Specifically, both ends of the roll are respectively inserted into the gaps between each set of lifting rollers 501, utilizing the gaps to achieve automatic centering, bearing, and positioning of the roll. The roll rotates as the lifting rollers 501 rotate.

[0063] The end of the rotating column 508 is coaxially provided with a mating groove 506 for cooperating with the docking part (i.e., the rotating top column 706) of the clamping drive mechanism 7; the clamping drive mechanism 7 inputs rotational power into the rotating column 508 through the mating groove 506, and through the meshing transmission of the rotating drive gear 503 and the lifting wheel 501, it finally drives the roller to rotate.

[0064] In a further embodiment, the lifting roller 501 and the bearing housing 505 are provided with alignment arrows 504; before operation, the vision acquisition mechanism 8 acquires images of the alignment arrows 504, and the clamping drive mechanism 7 drives the roller to rotate slowly, aligning the two alignment arrows 504, which serve as the reference zero position for the circumferential rotation of the roller; the end of the rotating column 508 is provided with an indexing arrow 507, and the bearing housing 505 is provided with an indexing mark 509 centered on the central axis of the rotating column 508; after the reference is established, the alignment arrows 504 are aligned with the bearing housing 505. 4. Alignment: The indexing arrow 507 points to the initial position on the indexing mark 509. If a defect is detected at a certain circumferential position of the roll, the clamping drive mechanism 7 can record the rotation drive angle at the moment of detection. During unloading, the worker can manually rotate the roll to the corresponding angle by checking the direction of the indexing arrow 507 on the indexing mark 509, thus quickly moving the defect position to a position that is easy to handle. The indexing mark 509 is designed according to a transmission ratio (2:1), and each overlap of the arrows is equivalent to the roll theoretically completing 2 revolutions, used for manual rough angle reading and periodic verification. Alternatively, the reference zero position can also be established based on the surface features of the roll.

[0065] See Figure 5 In a specific embodiment, the functional box mechanism 3 includes an outer box 301, a lifting and moving box 309, and a mixing box 307;

[0066] The outer casing 301 has a receiving cavity 311 in its inner wall. At least four conduits 308 communicating with the receiving cavity 311 are vertically connected to the upper end of the outer casing 301. The conduits 308 extend to the outside through the integrated casing assembly 1 and guide the lifting and lowering of the outer casing 301. The free end of the conduit 308 is connected to the water supply mechanism through a pipeline. A water spray hole 302 communicating with the receiving cavity 311 is opened at a preset position on the inner wall of the outer casing 301. The water spray hole 302 is directly facing the roller and can rinse the surface of the roller when spraying water.

[0067] A lifting and moving box 309 is installed on the top of the outer casing 301. A limit block 306 is provided on the section of the lifting and moving box 309 located inside the outer casing 301. Multiple tension springs 310 are provided between the limit block 306 and the inner top wall of the outer casing 301. A preset interface on the lifting and moving box 309 is connected to the air supply mechanism through a pipeline. A mixing box 307 is provided at the lower end of the lifting and moving box 309. Air inlets 305 are densely distributed on the section of the mixing box 307 located inside the lifting and moving box 309. An air outlet window 304 is provided at the lower end of the mixing box 307. Air enters the lifting and moving box 309 in sequence, enters the mixing box 307 through the air inlets 305, mixes, and is sprayed out from the air outlet window 304 to dry the surface of the roll and blow away the water mist generated during washing.

[0068] The upper end of the lifting moving box 309 is connected to the output end of the lifting drive mechanism 4, which is used to drive the lifting moving box 309 and the outer box 301 to move up and down; the upper end of the lifting moving box 309 is also provided with a lifting distance measuring component 312 for measuring distance, which is used to detect the displacement distance of the lifting moving box 309.

[0069] In a further embodiment, flexible bristles 303 adapted to the outer periphery of the roller are provided on both sides of the air outlet window 304 at the lower end of the mixing box 307. The lower ends of the bristles 303 abut against the surface of the roller and are brushed as the roller rotates. When air is blown out of the air outlet window 304, the residue on the bristles 303 can also be blown away.

[0070] Lifting and lowering process: When the lifting drive mechanism 4 drives the lifting moving box 309 to move upward, the limit block 306 moves upward and abuts against the inner top wall of the outer box 301, the tension spring 310 is compressed, thereby driving the outer box 301 to move upward together, opening the cleaning space to allow the rollers to enter and exit; when the lifting drive mechanism 4 drives the lifting moving box 309 to move downward, the outer box 301 moves downward accordingly, the outer box 301 first covers the rollers and falls on the moving drive mechanism 6, then the lifting moving box 309... As the roller continues to move downward, the limiting block 306 moves away from the inner top wall of the outer casing 301, and the tension spring 310 is stretched. Under the action of the spring, the outer casing 301 is pressed downward. At the same time, the mixing box 307 continues to move downward with the lifting moving box 309, so that the brush bristles 303 adhere to the surface of the roller with a certain clamping force. At this time, the clamping drive mechanism 7 drives the roller to rotate and the water spray hole 302 sprays water to rinse. The brush bristles 303 perform circumferential brushing on the surface of the roller, which significantly improves the cleaning efficiency and cleaning effect.

[0071] See Figure 6 In a specific embodiment, the visual acquisition mechanism 8 includes a support assembly 803, on which multiple camera modules 801 and multiple light source modules 802 are mounted. During detection, the light source modules 802 provide supplementary lighting to the roll surface, while the camera modules 801 perform visual acquisition of the roll surface. Simultaneously, the roll rotates, and the visual acquisition mechanism 8 detects the surface condition and appearance defects of the roll before and after cleaning, enabling comparison of cleaning effects and determination of surface quality.

[0072] See Figure 7In a specific embodiment, the clamping drive mechanism 7 includes a movable plate assembly 705 and an annular housing 707; the movable plate assembly 705 is arranged at the front end of the annular housing 707 and a sliding unit 702 is arranged at the rear end; a rotating top column 706 is rotatably arranged on the movable plate assembly 705 along the axial direction, and the end of the rotating top column 706 is connected to the docking part (fitting groove 506) on the positioning and bearing drive mechanism 5; a rotating drive assembly 701 is arranged on the movable plate assembly 705, and the output end of the rotating drive assembly 701 is coaxially connected to the rotating top column 706, driving the rotating top column 706 to rotate, and can detect and feedback the rotation angle of the rotating top column 706 in real time, thereby calculating the rotation angle and number of rotations of the roll. Specifically, the rotating drive assembly 701 includes a motor and an encoder.

[0073] The rear end of the movable plate assembly 705 is provided with a movable column 704 that is inserted into the annular box 707. The preset interface on the annular box 707 is connected to the air supply mechanism through a pipeline. When the annular box 707 is inflated, the air pressure pushes the movable column 704 to move, which in turn pushes the movable plate assembly 705 forward together with the rotating top column 706, so that the end of the rotating top column 706 docks with the matching groove 506 on the positioning and bearing drive mechanism 5. After the pressure is released, the movable plate assembly 705 retracts and resets, realizing a quick switch between docking and disengagement. After the rotating top column 706 docks with the matching groove 506, under the sliding action of the sliding unit 702, the movable drive mechanism 6 moves the positioning and bearing drive mechanism 5 and then drives the annular box 707 to move together, so that the annular box 707 can passively follow the roll between the inspection station and the cleaning and drying station, ensuring that docking can be achieved when the roll is moved to any station.

[0074] The movable plate assembly 705 is also equipped with a dimension measuring component 703. After the rotating top column 706 is engaged with the positioning bearing drive mechanism 5, it measures the distance between the two end faces of the roll as a reference to detect the total length of the roll. During the movement of the roll, the dimension measuring component 703 scans the end of the roll, thereby detecting the length of the steps at both ends of the roll. In a further embodiment, the end of the rotating top column 706 has a frustum conical structure.

[0075] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
