Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of forging production, more particularly, it relates to a rolling ring station measuring device and method for wind power flange. BACKGROUND

[0002] The wind power flange is a key connecting component of the tower drum of a wind turbine generator set, and the dimensional accuracy thereof is directly related to the safety and reliability of the entire machine. Such a large ring is usually formed by rolling ring process, that is, through the continuous rolling of the rolling mill, the radial deformation of the ring blank is generated until the target size is reached. Since the rolling process belongs to hot incremental forming, dynamic monitoring and accurate measurement of the size of the workpiece are the core link to ensure that the final product meets the design requirements.

[0003] In the existing production process, the size measurement of the flange during the rolling process generally relies on traditional manual methods. Specifically, the operator needs to use large calipers, templates and other simple tools to measure the key dimensions of the workpiece such as the outer diameter, inner diameter and height step by step and offline after the rolling mill is intermittently stopped. During measurement, the measurement tool needs to be moved close to the high-temperature workpiece for comparison and reading, or the workpiece needs to be unloaded from the station with the help of hoisting equipment and transported to a specific detection platform for measurement. Then, the rolling process parameters are adjusted empirically based on the measurement results.

[0004] However, the above-mentioned traditional measurement method has a series of problems to be solved. First, the hoisting and placement of the workpiece cannot guarantee accurate centering with the measurement reference, and the lack of effective self-adaptive centering mechanism causes inherent errors in the measurement results due to the non-uniformity of the reference, which cannot provide reliable basis for subsequent processing. Secondly, the step-by-step measurement process is not only inefficient, resulting in too long equipment downtime, but more seriously, it cannot obtain synchronous size data of multiple dimensions of the workpiece at the same time node. This asynchrony makes it difficult for the operator to fully judge the true roundness and shape of the workpiece. In addition, during the measurement process, the contact force generated when the measurement tool contacts the high-temperature workpiece, or the lack of rigidity of the measurement device itself, can easily disturb the rolling workpiece which is in a delicate force balance, and even cause it to move slightly. This interference will further damage the accuracy of the measurement, making the measurement process fall into an inefficient cycle of "measurement-disturbance-re-measurement".

[0005] Therefore, in order to solve the above technical problems, the present application provides a rolling ring station measuring device and method for wind power flange. SUMMARY

Detailed Implementation

[0022] Example 1: like Figures 1-10 As shown, this invention provides a ring rolling station adjustment and testing device for wind turbine flanges, including a support base 1 and a measuring base 2 mounted on the support base 1. The measuring base 2 is equipped with a telescopic device 3. The telescopic device 3 is a prior art device whose power end can perform vertical displacement, which will not be described in detail here. It also includes: The positioning component 5, which is set on the support base 1, is used to center and lock itself according to the self-weight of the flange rolling ring. It includes a placement and compression structure set on the support base 1, and multiple sets of moving positioning structures are arranged around the circumference of the placement and compression structure. The placing compression structure is self-compressed due to the self-gravity of the flange ring, the moving positioning structure is driven to rotate towards the center of the placing compression structure by the compression displacement of the placing compression structure, and multiple sets of the moving positioning structure jointly limit the flange ring to be positioned at the center of the placing compression structure. The placing compression structure comprises a support column 501 arranged on the support base 1, and the upper end of the support column 501 is provided with a workbench 502, the workbench 502 is internally provided with an embedding cavity, and the support column 501 can enter the cavity of the workbench 502; in the embodiment, after the forging is placed on the surface of the workbench 502, the workbench 502 moves downward, and the top end of the support column 501 enters the cavity of the workbench 502. The support column 501 is further provided with a receiving table 503, the receiving table 503 is provided with a plurality of sets of compression elastic components, the compression elastic component comprises a pressure-bearing telescopic rod 504 arranged on the receiving table 503, the top end of the pressure-bearing telescopic rod 504 is fixedly connected with the bottom surface of the workbench 502, the bottom end of the pressure-bearing telescopic rod 504 is fixedly connected with the top end of the receiving table 503, and the outer side of the pressure-bearing telescopic rod 504 is provided with a pressure-bearing spring 505, one end of the pressure-bearing spring 505 is fixedly connected with the bottom surface of the workbench 502, and the other end of the pressure-bearing spring 505 is fixedly connected with the top end of the receiving table 503. It should be noted that when the flange ring forging is placed on the surface of the workbench 502, the workbench 502 is in a sunken state and gradually moves downward through the buffering of the pressure-bearing spring 505 and the pressure-bearing telescopic rod 504. In the embodiment, when the heavy flange is placed on the surface of the workbench 502, the self-weight of the heavy flange overcomes the elastic force of the compression elastic component and drives the workbench 502 to produce a compression displacement downward, and the displacement is the initial input of the entire positioning process. The support column 501 is further provided with a fixing table 506, a plurality of inclined grooves 512 are circumferentially arranged on the fixing table 506, and it should be noted that the inclined groove 512 is a sliding groove with shallow depth at one end, deep depth at the other end and smooth transition in the middle, and the cross section of the inclined groove 512 can be triangular. Each set of the moving positioning structure corresponds to the position of the inclined groove 512, and the moving positioning structure comprises a guard plate 507 arranged on the circumference of the workbench 502, the guard plate 507 is rotatably installed with a positioning connecting rod 508 through a rotating shaft, the upper end of the positioning connecting rod 508 is provided with a torsion spring shaft 509, the torsion spring shaft 509 is coupled with a positioning push plate 510, the lower end of the positioning connecting rod 508 is provided with a positioning roller 511, the positioning roller 511 moves in the inclined groove 512, and the inclined groove 512 is limited by the groove for the positioning roller 511. It should be noted that the positioning connecting rod 508 is folded, and has a folding degree, which enables the lower end of the positioning connecting rod 508 to slide along the inclined surface of the inclined groove 512 when the positioning connecting rod 508 rotates around the rotation shaft, and the positioning push plate 510 is an elastic steel plate with a certain arc, when the elastic steel plate with an arc contacts the circumferential surface of the flange rolling ring, the elastic arc surface of the positioning push plate 510 will bend according to the arc of the circumferential surface of the flange rolling ring, so that the surface of the positioning push plate 510 is fitted with the circumferential surface of the flange rolling ring, and the torsion spring shaft 509 enables the positioning push plate 510 to rotate around the axis, and the original set angle is restored when the positioning push plate 510 is separated from the flange rolling ring; In the embodiment, when the self-weight of the flange rolling ring presses the workbench 502 and makes it move downward, at this time the positioning roller 511 at the lower end of the positioning connecting rod 508 will slide in the inclined groove 512, and the positioning roller 511 will be pressed to slide from the shallow position to the deep position, which macroscopically indicates that the lower end of the positioning connecting rod 508 moves from the center to the circumferential edge of the fixed table 506, and since the positioning connecting rod 508 rotates around the rotation shaft, according to the principle of lever, the outward swing of the lower end of the connecting rod will inevitably cause the centripetal swing of the upper end of the connecting rod around the rotation shaft, and the upper ends of the plurality of circumferentially distributed connecting rods are then simultaneously gathered to the center, and the positioning push plate 510 gradually bends under the action of the torsion spring shaft 509, and since the positioning push plate 510 is an elastic arc plate, it will automatically fit the circumferential surface of the flange rolling ring, facilitating the pushing of the flange rolling ring, and the positioning push plate 510 at the upper end of the connecting rod fits the outer circle of the flange under the action of the torsion spring, and the elastic arc surface design can adapt to different diameters and small amount of out-of-roundness, realize surface contact, and uniformly apply force; The surface of the workbench 502 is provided with a plurality of balls 513 for reducing the friction between the flange rolling ring and the surface of the workbench 502, and the surface of the workbench 502 is provided with an anti-collision groove corresponding to the position of the positioning connecting rod 508; It should be noted that since the self-weight of the flange rolling ring is large, the pushing force of the positioning push plate 510 is large enough, and the synchronous centripetal motion of the plurality of positioning push plates 510 accurately pushes the flange to the center of the workbench 502 to complete positioning, and the design of the balls 513 on the surface of the workbench 502 greatly reduces the friction force of pushing the flange, making the centering process smooth and accurate; The flange self-weight drives the movement of the positioning assembly 5, which first realizes the automatic unification and high-precision positioning of the workpiece reference, effectively eliminating the measurement error caused by the placement deviation; on this basis, the elastic arc positioning push plate 510 and the gravity continuous locking mechanism give the device better adaptability and stability, which can resist disturbance during measurement and firmly maintain the positioning reference; in addition, this process completely utilizes the workpiece gravity as a power source, without the need for external energy, and the structure is simple and reliable. This automatic operation of "placing and positioning" not only greatly shortens the auxiliary time of adjustment and measurement, improves the production efficiency, but also reduces manual intervention, and ensures the safety of heavy workpiece operation.

[0023] It is important to emphasize that this center positioning function realizes the automatic unification of the workpiece reference by purely mechanical means, establishing a unique and accurate origin for all subsequent measurements.

[0024] Working principle of gravity self-locking positioning: The operator places the heavy flange forging on the table surface of the workbench 502 by hoisting equipment, and the huge self-weight of the flange immediately acts on the workbench 502, overcoming the pre-tightening force of the pressure spring 505, and driving the entire workbench 502 to stably sink along the axial direction of the support column 501. This sinking action is the initial trigger signal of the entire positioning process, and the vertical downward displacement of the workbench 502 is the input source for all subsequent actions. When the workbench 502 sinks, the guard plate 507 fixed on its circumference also synchronously moves downward, and the folding positioning link 508 hinged on the guard plate 507 through a rotating shaft is thus subjected to a downward pulling force. The positioning roller 511 at the lower end of the positioning link 508 is originally placed at the shallowest part of the inclined groove 512 of the fixed table 506. When the downward pulling force is transmitted to the positioning link 508, the positioning roller 511 is forced to roll from the shallow end to the deep end of the inclined groove 512 under the constraint of the inclined groove 512. Due to the change in the depth of the inclined groove 512, the pure vertical downward movement of the positioning roller 511 is forcibly converted into a horizontal directional component by the inclined surface of the inclined groove 512, resulting in the outward swinging of the lower end of the positioning link 508 (away from the center of the support column 501). The folding positioning link 508 is essentially a lever, and the rotating shaft at its middle part is the fulcrum. According to the principle of the lever, the outward swinging of the lower end of the positioning link 508 inevitably leads to the centripetal swinging of the upper end of the positioning link 508 around the fulcrum, which is in the opposite direction towards the center of the support column 501. Since the inclined groove 512 is circumferentially uniform, all positioning links 508 follow the same movement law, and therefore, the upper ends of all positioning links 508 are synchronously and uniformly gathered towards the center. With the centripetal movement of the upper end of the positioning link 508, the positioning push plate 510 connected through the torsional spring shaft 509 at the end of the positioning link 508 gradually contacts the outer circumferential surface of the flange. The torsional spring shaft 509 ensures that the push plate can adaptively adhere to the workpiece surface, and the elastic curved surface of the push plate itself allows it to further adhere to flanges with different diameters or slightly different curved surfaces, realizing flexible surface contact and avoiding damage or inaccurate positioning caused by point contact. The uniform centripetal force generated by multiple push plates pushes the flange to fine-tune its position on the workbench 502, and the distributed ball bearings 513 on the table surface greatly reduce the friction, allowing the flange to be easily and smoothly moved. Finally, under the joint action of the circumferentially distributed positioning push plates 510, the flange is accurately corrected to the geometric center of the workbench 502, completing the automatic centering.

[0025] The three-position measuring assembly 4 is further provided with a stabilizing component for stabilizing the positioning of the flange rolling ring, the stabilizing component comprising a pressing seat 6, the bottom end of the pressing seat 6 being provided with a pressing plate 7.

[0026] It should be noted that the pressing plate 7 is located above the horizontal line of the probe, when the telescopic device 3 drives the three-position measuring assembly 4 to move downward, the outer ring probe 408 and the inner ring probe 411 will sink to below the surface of the flange rolling ring one step ahead of the pressing plate 7, at this time, the outer ring probe 408 is located on the circumferential outside, and the inner ring probe 411 is located on the inside of the inner circle; In the embodiment, when the telescopic device 3 moves downward as a whole, the pressing plate 7 is first pressed against the upper surface of the flange which has completed the preliminary centering, an additional vertical downward pressure is applied, the pressure is superimposed with the weight of the workpiece, the self-locking effect of the centering mechanism is significantly enhanced, the posture of the workpiece on the table is more stable, this action ensures that the workpiece will not be slightly deviated due to the contact force when the subsequent measuring probe contacts the workpiece, and provides an important static reference guarantee for high-precision measurement; The three-position measuring assembly 4 arranged at the lower end of the telescopic device 3 is used for measuring the outer diameter, the inner diameter and the depth of the flange rolling ring, comprising an outer ring probe 408, an inner ring probe 411 and a depth probe 413 which move according to the center position of the flange; The three-position measuring assembly 4 further comprises a transmission box 401 arranged at the lower end of the telescopic device 3, the transmission box 401 is internally provided with a driving motor 402, the power output end of the driving motor 402 is provided with a driving gear 403, the transmission box 401 is rotationally provided with a threaded rod 404 inside, the threaded rod 404 is provided with a driven gear 405 which is engaged with the driving gear 403, the two ends of the threaded rod 404 are both threadedly connected with a moving plate 406, each moving plate 406 is provided with a differential allowing component 407 which has elastic contraction displacement, the outer ring probe 408 and the inner ring probe 411 are respectively connected with one group of differential allowing components 407, the differential allowing component 407 comprises a differential allowing telescopic rod 4071 arranged on the side of the moving plate 406, the outer side of the differential allowing telescopic rod 4071 is provided with a differential allowing spring 4072, the transmission box 401 is provided with a guide rod 409 which penetrates through the moving plate 406 on the symmetrical two sides, the tail end of the guide rod 409 and the tail end of the threaded rod 404 are jointly connected with a mounting plate 410; Among them, one end of the differential allowing telescopic rod 4071 is connected with the probe, the other end of the differential allowing telescopic rod 4071 is connected with the moving plate 406, one end of the differential allowing spring 4072 is connected with the probe, the other end of the differential allowing spring 4072 is connected with the moving plate 406, wherein the differential allowing component 407 and the moving plate 406 connected with the outer ring probe 408 are located at one end of the threaded rod 404 close to the circumference of the workbench 502, the differential allowing component 407 and the moving plate 406 connected with the inner ring probe 411 are located at one end of the threaded rod 404 close to the center of the workbench 502; It should be noted that in the initial state, the outer ring probe 408 is located outside the outer ring of the flange ring after moving downward by the telescopic device 3, and the inner ring probe 411 is located inside the inner ring of the flange ring after moving downward by the telescopic device 3; The driving motor 402 drives the driving gear 403 to rotate, thereby driving the driven gear 405 and the threaded rod 404 to rotate. At this time, the outer ring probe 408 and the inner ring probe 411 located outside the flange circumference and inside the inner circle move in the same direction. When one of the two probes first contacts the inner circle or the outer circle, and the other probe has not yet contacted, the driving motor 402 is still driven. The probe contacting the surface of the flange ring has an error-allowed relative fixed displacement due to the action of the error-allowed spring 4072 and the error-allowed telescopic rod 4071 in the error-allowed component, which ensures that the two probes cannot be simultaneously measured due to the change of the inner diameter and the outer diameter of the flange. At the same time, when the probe contacts the surface of the workpiece, the error-allowed component 407 allows the probe to retract slightly after overcoming the spring force, which ensures that both probes can reliably contact the surface even if the workpiece has a small amount of out-of-roundness, avoiding the measurement failure problem of "one contact, one suspended" caused by size changes. The bottom end of the transmission box 401 is provided with an electric telescopic rod 412, and the end of the electric telescopic rod 412 is provided with a depth probe 413. The outer surface of the movable end of the electric telescopic rod 412 is circumferentially provided with a clamping plate 414. It should be noted that the clamping plate 414 has a certain length, so that it can be blocked by the inner circle of the flange when contacting the surface of the flange, and cannot continue to sink with the depth probe 413. The clamping plate 414 is provided with a clamping spring 415, one end of which is connected with the clamping plate 414, and the other end is connected with the bottom end of the transmission box 401. When the lower pressing plate 7 fixes the flange forging, the telescopic device 3 stops moving, and at this time the electric telescopic rod 412 starts to drive the depth probe 413 to move downward. Since the clamping plate 414 contacts the surface of the flange and cannot continue to sink, the depth probe 413 continues to sink. When the depth probe 413 touches the bottom, the displacement distance from the bottom of the flange to the clamping plate 414 can be measured, that is, the depth of the flange. The stable component integrated in the three-position measurement assembly 4 in the embodiment can press the workpiece before measurement, combine the weight of the workpiece with the additional downward pressure, greatly enhance the stability of the positioning assembly 5, effectively eliminate the micro displacement that may be caused when the measurement probe contacts the workpiece, and ensure the relative static of the measurement reference during the entire process. Relying on the accurate positioning, the three-position measurement assembly 4 synchronously drives the double-side probes by the driving motor 402, cooperates with the unique differential allowance component 407, and realizes the synchronous and adaptive measurement of the outer diameter and the inner diameter. This not only guarantees the same time of data acquisition and improves the measurement efficiency, but also ensures that all size measurements are based on the same center reference, thereby overcoming the measurement risk caused by the non-uniform reference or the geometric error of the workpiece, significantly improving the overall reliability and precision of the measurement. The three-position measurement assembly 4 also accurately measures the depth based on the fixed workpiece, and has a simple and reliable structure. Through the ingenious design of mechanical linkage, the whole system forms an efficient measurement process based on accurate centering, stable pressing, and synchronous measurement. In the case of no complex sensor, high-efficiency, high-precision, and high-stability comprehensive measurement are realized, which is especially suitable for the prominent working conditions of heavy flange rings.

[0027] Working principle of the measurement process: 1. Stable pressing After the automatic centering and self-locking of the flange workpiece are completed, the telescopic device 3 drives the whole three-position measurement assembly 4 and the stable component above to descend synchronously. In the descending process, the lower pressing plate 7 of the stable component will first contact and press the upper surface of the flange due to its higher position. The additional downward pressure and the gravity of the workpiece are superimposed, which greatly enhances the self-locking effect of the centering mechanism, firmly locks the workpiece in the centered position, and forms a stable measurement reference. This process effectively prevents any micro-displacement that may be caused by the subsequent probe contact; 2. Radial synchronous measurement After the stable component presses the workpiece and the telescopic device 3 stops descending, the driving motor 402 in the transmission box 401 starts to work. Through the driving gear 403, the driving motor 402 synchronously drives the driven gear 405 on the threaded rod 404, so that the threaded rod 404 rotates. The rotation of the threaded rod 404 drives the moving plate 406, the outer circle probe 408, and the inner circle probe 411 on it to move synchronously and oppositely in the radial direction, respectively approaching the outer circle and the inner circle of the flange; When one of the probes (for example, the inner circle probe 411) first contacts the workpiece surface, the differential allowance spring 4072 in the differential allowance component 407 behind it is compressed, allowing the probe to have a small amount of elastic retraction displacement. The driving motor 402 continues to operate until the other probe (the outer circle probe 408) also reliably contacts the workpiece, ensuring that even if the workpiece has a roundness error, both probes can obtain effective measurement contact points at the same time. The workers record the final mechanical position of each probe moving plate 406, and then the accurate outer diameter and inner diameter sizes can be calculated; 3. Depth measurement After the radial measurement is completed or during the process, the electric telescopic rod 412 at the bottom of the transmission box 401 starts to work, driving the depth probe 413 to move downward. During the downward movement, the reference plate 414, which is fitted outside the electric telescopic rod 412, first contacts the upper surface of the flange and then stops moving downward (its position is limited by the flange surface), while the depth probe 413 continues to move downward until it contacts the bottom surface to be measured (such as the stepped surface of the flange). The extension displacement of the depth probe 413 relative to the reference plate 414 is the depth or thickness dimension of the flange. The design of the reference plate 414 eliminates the error caused by the workpiece installation tilt or surface unevenness in the depth measurement. Example

[0028] like Figures 1-10 As shown, this invention provides a method for adjusting and testing the rolling ring of a wind turbine flange, comprising the following steps: S1: Begin placing the flange ring forging on the compression structure; S2: The compression structure begins to move downwards due to the pressure of the weight of the flange ring forging; S3: The moving positioning structure distributed around the circumference of the flange rolling ring begins to squeeze towards the center of the flange rolling ring from the circumferential edge through the downward moving placement compression structure. S4: The compressed flange ring is gradually pushed towards the center of the compression structure by the moving positioning structure. Due to the large weight of the flange ring, when the flange ring finally stabilizes, the flange ring has been fixed by the multi-directional compression of the moving positioning structure. S5: At this time, the telescopic structure drives the three-position measurement component 4 to move downward; S6: When the three-position measuring component 4 moves down, the stabilizing component connected to it moves down synchronously. When the stabilizing component contacts the surface of the flange forging, it presses down on the flange rolling ring to stabilize the flange rolling ring. S7: Finally, the outer ring probe 408, inner ring probe 411, and depth probe 413 simultaneously measure the outer diameter, inner diameter, and depth of the flange rolling ring.
