Description

Technical Field

[0001] The present invention relates to the technical field of wind power flange measurement, and particularly to an ovality detection tooling for wind power flanges. Background Art

[0002] Wind power flanges are mainly used for connecting wind turbine towers. By welding flanges at the ends of wind turbine towers, subsequent assembly work is facilitated. In the manufacturing of wind power flanges, since wind power flanges play an important role in the installation stability of wind turbine towers, it is necessary to detect their processing accuracy during the manufacturing of wind power flanges to avoid excessive errors such as ovality affecting subsequent assembly and safety. The end face accuracy of the flange will also directly affect parameters such as ovality after flange installation. Currently, the ovality detection of wind power flanges mostly uses manual inspection tools for relevant detection work. Thanks to the relatively flexible detection, it is also widely used. However, for flanges with a large volume, the detection work is time-consuming and laborious, and it is difficult to ensure the measurement accuracy. Most of the measurement data is the measurement of the diameter. At the same time, it is not convenient to axially press and position the flange, and the axial deformation of the flange itself is not convenient for automatic control during detection, which affects the measurement accuracy. It is also not convenient to comprehensively detect the perpendicularity and hole diameter position of the processing accuracy of the flange hole and the end face. Poor flange hole accuracy will directly affect the flange assembly quality. Summary of the Invention

The fitting mounting block 301 is slidably installed on the left sliding block 203; two pressing rollers 302 are rotatably installed on the fitting mounting block 301 through brackets; two propulsion sliding shafts 303 are fixedly installed on the fitting mounting block 301, and sliding shaft sleeves 304 are respectively slidably sleeved on the two propulsion sliding shafts 303; the two sliding shaft sleeves 304 are respectively fixedly installed on both sides of the same-side sliding cylinder 201; through holes are respectively provided on the two propulsion sliding shafts 303; springs are respectively sleeved on the two propulsion sliding shafts 303; the fitting mounting block 301 slides telescopically to adapt to the diameter of the flange; the elastic fitting member 3 further includes: positioning pins 305, moving rollers 306, and a driving rotary motor 307.

[0038] In the embodiments of the present disclosure, the detection adapter 4 includes a propulsion adjustment frame 401 and an adjustment lead screw 402. The propulsion adjustment frame 401 is slidably mounted on the fitting mounting block 301. The adjustment lead screw 402 is threadedly connected to the propulsion adjustment frame 401. The adjustment lead screw 402 is rotatably mounted on the fitting mounting block 301. A ball sleeve is provided on the propulsion adjustment frame 401. The end face adaptation detection member 5 includes an end face adaptation ball 501, an end face fitting cylinder 502, and an end face fitting tension spring 503. The end face adaptation ball 501 is sleeved in the ball sleeve on the propulsion adjustment frame 401. The end face fitting cylinder 502 is slidably inserted into the end face adaptation ball 501. The end face fitting tension spring 503 is sleeved on the end face fitting cylinder 502, and the end face fitting tension spring 503 is connected between the end face adaptation ball 501 and the end face fitting cylinder 502. The end face fitting cylinder 502 is used to be attached to the flange end face. The end face adaptation detection member 5 further includes a detection shaft 504 and an insertion extrusion spring 505. The detection shaft 504 is slidably inserted into the end face fitting cylinder 502. The insertion extrusion spring 505 is sleeved on the detection shaft 504, and the insertion extrusion spring 505 is located inside the end face fitting cylinder 502. The insertion extrusion spring 505 is connected between the end face fitting cylinder 502 and the detection shaft 504. The bottom of the detection shaft 504 is a conical structure. A scale is provided on the detection shaft 504. The conical structure at the bottom of the detection shaft 504 is used to be inserted into the flange hole. The perpendicularity test member 6 includes a vertical detection frame 601, a lifting slide plate 602, a docking conical column 603, and an upward pulling spring 604. The lifting slide plate 602 is slidably mounted on the vertical detection frame 601, and the lifting slide plate 602 is fixedly sleeved on the end face fitting cylinder 502. The docking conical column 603 is fixedly mounted at the bottom of the vertical detection frame 601, and the top of the docking conical column 603 is a conical structure. The top of the vertical detection frame 601 is slidably sleeved above the detection shaft 504. The upward pulling spring 604 is sleeved on the vertical detection frame 601.The upward pulling spring 604 is located between the vertical detection frame 601 and the lifting slide plate 602. By using the perpendicularity test piece 6 and the end face adaptation detection piece 5, the end face of the flange can be adapted and detected, and the machining accuracy of the flange holes on the flange end face can be detected in real time. This structure uses the docking conical column 603 and the detection shaft 504 to achieve real-time insertion into the flange holes for detection. By moving the conical detection structure on the flange end face, the flatness of the flange end face can be measured. At the same time, by using the conical structure, the diameter and the perpendicularity of the opening of the flange holes can be measured in sequence. The end face fitting cylinder 502 can be used to fit the flange end face in real time, and the accuracy of the subsequent measurement work is higher, which can effectively ensure the detection quality of the flange holes. Multiple parameter detections can be carried out at one time, and the perpendicularity of the flange holes is easy to obtain. The detection method of this structure utilizes the characteristics of the conical structure, effectively improving the measurement efficiency of a circle of flange holes on the flange. By using the end face fitting tension spring 503, the end face fitting cylinder 502 can be driven to adhere to the flange end face by pulling. By using the multi-directional adaptation of the end face adaptation ball 501, the end face fitting cylinder 502 can be vertically attached to the flange end face, ensuring the accuracy of the subsequent perpendicularity detection. If the depth dimension of the detection shaft 504 inserted into the flange hole is too small or too large, it reflects the deviation of the flange hole diameter or the deviation of the opening position of the flange hole on the flange, either inward or outward. At the same time, under the extrusion of the upward pulling spring 604, the vertical detection frame 601 can drive the docking conical column 603 to insert into the bottom flange hole. If the value displayed on the detection shaft 504 corresponding to the top of the docking conical column 603 at this time is inconsistent with the value of the detection shaft 504 inserted downward by itself, it proves that the opening positions on both sides are offset and not perpendicular at this time. If the bottom docking conical column 603 is not completely inserted into the flange hole, it means that the opening perpendicularity of the flange hole does not meet the standard at this time. The docking conical column 603 and the detection shaft 504 of the conical structure can be disengaged from the flange hole to achieve fitting and detection on the flange end face, and the structure is more reasonable, and the end face flatness can be quickly displayed.

[0039] Embodiment 2, on the basis of Embodiment 1, the magnetic attraction pressing member 7 includes: a magnetic attraction traction block 701 and an electromagnet 702. The magnetic attraction traction block 701 is fixedly installed at the bottom of the fitting installation block 301; an electromagnet 702 is fixedly installed at the bottom of the magnetic attraction traction block 701; the electromagnet 702 is used to magnetically attract and detect the support disc 101; two rollers are rotatably installed at the bottom of the magnetic attraction traction block 701, and the two rollers at the bottom of the magnetic attraction traction block 701 are attached to the detection support disc 101. The magnetic attraction pressing member 7 can be used to assist in pulling the sliding cylinder 201 magnetically, driving the pressing roller 302 on the fitting installation block 301 to press the flange. The measurement of the flange is more stable. Because after a flange with a larger diameter is placed on the flange support ring, there is a poor fitting degree locally. Avoiding the situation that the flange with a larger diameter is not tightly attached to the flange support ring axially can improve the reliability of the detection data. Because when the actual flanges are installed and connected by bolts, the flanges will maintain a planar fit. The magnetic attraction control adopted in this structure is also simpler and more convenient.

[0040] Working principle of this embodiment: First, lift and install the flange on the flange support ring 106. It is only necessary to achieve concentricity simply, and precise alignment is not required. When lifting the flange, rotate and adjust the screw rod 402 to drive the propulsion adjustment frame 401 to move outward to facilitate the placement of the flange. After the flange is placed, drive the propulsion adjustment frame 401 to move inward to reset. By activating the electromagnet 702 to magnetically attract and detect the support disc 101, and cooperating with the rollers at the bottom of the magnetic attraction traction block 701 for support, the automatic adapter 2 can be driven to move downward as a whole, driving the two moving rollers 306 and the two rollers on the fitting wheel frame 204 to be placed inside the flange. At the same time, the pressing roller 302 will also be driven to press down on the flange for flattening work. Subsequently, by rotating the reverse screw rod 202, drive the two sliding blocks 203 to expand outward simultaneously, and use the two moving rollers 306 and the two rollers on the fitting wheel frame 204 to centrally clamp the flange. During this process, the adapter positioning disc 102 can be driven to adjust the initial position. Subsequently, the positioning bolt 105 can be tightened to position the adapter positioning disc 102. At this time, the position of the adapter positioning disc 102 is the center point of the current two moving rollers 306 and the two rollers on the fitting wheel frame 204. Subsequently, pull out the positioning pin 305, and drive the moving roller 306 to rotate by driving the rotary motor 307, driving the automatic adapter 2 to rotate around the flange as a whole. The propulsion sliding shaft 303 without a limit will be pushed by the spring sleeved on itself to push the moving roller 306 to always fit the inner circle of the flange. If the ellipticity of the inner circle of the flange deviates at this time, its diameter will change. At this time, the distance between the two moving rollers 306 and the two rollers on the fitting wheel frame 204 changes, which can drive the elastic reading disc 103 below the sliding cylinder 201 to shift. At this time, the reading on the elastic reading disc 103 can be observed, and the readings in all directions on the elastic reading disc 103 can be observed in real time to obtain the offset amount at this time, with a more comprehensive display, to reflect the ellipticity of the wind power flange. Using the end face fitting tension spring 503, the end face fitting cylinder 502 can be driven to adhere to the flange end face by pulling. Using the multi-directional adaptation of the end face adapter ball 501, the end face fitting cylinder 502 can be vertically attached to the flange end face. When rotating and adjusting the screw rod 402 to control the retraction of the propulsion adjustment frame 401, the detection shaft 504 can be driven to correspond to the center of the flange hole. As the two moving rollers 306 drive the fitting and installation block 301 to move around the inner side of the flange, the detection shaft 504 can be driven to insert into the flange hole for detection. Using its conical structure, if the depth dimension of the detection shaft 504 inserted into the flange hole is too small or too large, it reflects that the diameter deviation of the flange hole or the opening position of the flange hole on the flange appears deviated, the opening position is too inward or too outward. At the same time, under the extrusion of the upward pulling spring 604, the vertical detection frame 601 can drive the docking conical column 603 to insert into the bottom flange hole. If the value corresponding to the detection shaft 504 at the top of the docking conical column 603 is inconsistent with the value of the detection shaft 504 itself inserted downward at this time, it means that the opening perpendicularity of the flange hole does not meet the standard at this time, which will cause a deviation when the docking conical column 603 is inserted into the flange hole and cannot correspond to the reference value.After the detection of the flange holes by the docking conical column 603 and the detection shaft 504 is completed, with the drive of the fitting mounting block 301, the docking conical column 603 with a conical structure and the detection shaft 504 can be disengaged from the flange holes to achieve detection while fitting on the flange end face. During the process, the scale on the detection shaft 504 can be observed manually in real time; after the ovality measurement is completed, the handles on the two propulsion sliding shafts 303 can be pulled back manually, and the positioning pins 305 can be inserted here for positioning to facilitate the subsequent flange measurement work.
