Description

Technical Field

[0001] The present invention belongs to the technical field of flange detection, and particularly relates to a large ring-shaped flange size detection device for a processing assembly line. Background Art

[0002] Large flanges are mainly used in large-diameter pipeline projects and are widely used in industries such as machinery, chemical engineering, wind power, and sewage treatment. Large flanges are usually made of low-alloy high-strength structural steel, such as S355NL steel. During the manufacturing process, it is necessary to strictly control the chemical composition and harmful element content of the steel ingot to reduce the inclusion content and improve the density of the forging; large ring-shaped flanges with a diameter ranging from 3.5 meters to 8 meters are essential components for the connection of wind turbine towers.

[0003] Currently, most existing large ring-shaped flanges are detected by manually operating a detection device in cooperation with a clamping and rotating mechanism for the ring-shaped flange. This detection method requires a large amount of time for the clamping and placement detection of workpieces, resulting in reduced detection efficiency and high manual labor intensity. Existing assembly line detections are mostly used for the automatic detection of small flanges. Due to the large volume and weight of large ring-shaped flanges, they are prone to contact wear or collision with other workpieces during the production and transportation processes. Therefore, it is very necessary to quickly detect large ring-shaped flanges. Through detection, it is possible to timely discover whether the dimensions of the products processed in the previous process on the assembly line are qualified, accurately control the quality of the products, and improve the qualification rate of the products. Since it is automatically detected on the production assembly line, this also reduces the manual labor intensity, shortens the detection time, and improves the production efficiency.

[0035] As Figure 1 —14 shows, the present invention provides a large ring-shaped part flange size detection device for a processing pipeline, including a transmission mechanism 1. Symmetrically arranged on both sides of the middle part of the transmission mechanism 1 are centering push mechanisms, and each centering push mechanism includes a slidable centering push plate 10; a liftable support plate 8 is arranged in the middle part of the transmission mechanism 1 through a lifting mechanism to support the flange through the support plate 8; a detection mechanism 3 is rotatably arranged above the middle part of the transmission mechanism 1.

The support bottom plate 5 is a horizontally arranged square plate-like structure. Support seats are fixedly arranged on the support bottom plate 5. A plurality of support rollers 6 are arranged equidistantly in the front-rear direction at the upper end of the support seats, and the support rollers 6 are horizontally arranged in the left-right direction. The plurality of support rollers 6 are connected by the synchronous transmission assembly, so that all the support rollers 6 can rotate synchronously.

[0037] A support frame 2 is fixedly arranged in the middle of the support bottom plate 5. The support frame 2 includes four support legs and a support flat plate. The support flat plate is a horizontally arranged square plate-like structure. A vertical support leg is fixedly arranged at each of the four corners of the lower end surface of the support flat plate. The lower ends of the four support legs are respectively fixedly connected to the left and right side edges of the middle part of the support bottom plate 5. The support flat plate is located above the middle of the transmission mechanism 1. A first motor 7 is fixedly arranged at the center of the upper end surface of the support flat plate. The output shaft of the first motor 7 is vertically downward. A vertical rotating shaft connecting rod 15 is fixedly arranged on the output shaft of the first motor 7.

[0038] A plurality of support plates 8 are arranged in the middle of the transmission mechanism 1, and the support plates 8 and the support rollers 6 are arranged in an alternating manner. A baffle 14 is fixedly arranged below the frontmost and rearmost support plates 8 respectively.

[0039] The centering pushing mechanism further includes a limit support platform 4 and a hydraulic cylinder 9. A horizontal limit support platform 4 is fixedly arranged on both sides of the middle part of the support bottom plate 5. A hydraulic cylinder 9 is fixedly arranged at the upper end of the limit support platform 4. The piston rod of the hydraulic cylinder 9 horizontally faces the side of the support roller 6. The centering push plate 10 is fixedly arranged at the end of the piston rod of the hydraulic cylinder 9. The centering push plate 10 is a "﹀"-shaped plate-like structure.

[0040] The lifting mechanism includes a second motor 11, a screw jack 12, a bevel gear commutator 13, a transverse transmission shaft, and a longitudinal transmission shaft.

[0041] Two screw jacks 12 are respectively arranged on the left and right below each support plate 8. The screw jacks 12 are fixedly arranged on the support bottom plate 5. The upper end of the screw of the screw jack 12 is fixedly sleeved with a lifting sleeve, and the lifting sleeve is rotatably arranged at the lower end surface of the support plate 8.

[0042] A second motor 11 is fixedly arranged on the upper end of the support bottom plate 5, and the output shaft of the second motor 11 is arranged along the front-rear direction.

[0043] The number of bevel gear commutators 13 is three, namely one T-shaped commutator and two SP-shaped commutators. The T-shaped commutator includes an input shaft and two output shafts on the left and right. The SP-shaped commutator includes an input shaft and an output shaft that are perpendicular to each other.

[0044] The transverse drive shaft is horizontally arranged along the left - right direction, and the longitudinal drive shaft is horizontally arranged along the front - back direction. The output shaft of the second motor 11 is fixedly connected to the input shaft of the T - type commutator. At each of the two output shafts of the T - type commutator, a transverse drive shaft is fixedly arranged. The ends of the two transverse drive shafts away from the T - type commutator are respectively fixedly connected to the input shafts of two SP - type commutators.

[0045] The second motor 11 drives the two transverse drive shafts to rotate synchronously through the T - type commutator. The two transverse drive shafts drive the two longitudinal drive shafts to rotate synchronously through the two SP - type commutators. The two longitudinal drive shafts drive the screw jacks 12 on the left and right sides to act synchronously. The screws of all the screw jacks 12 lift and lower synchronously, thereby driving all the support plates 8 to lift and lower synchronously, and further driving the flanges at the upper ends of the support plates 8 to lift and lower synchronously. All the support plates 8 lift and lower synchronously, so as to ensure that the flange is in a horizontal state and will not tilt accidentally, which affects the detection of the detection mechanism 3.

[0046] When the support plate 8 rises, the two ends of the support plate 8 are disengaged from the support seat; when the support plate 8 descends to contact the support seat, the support plate 8 descends to the lowest position. Since baffles 14 are fixedly arranged at the lower ends of the front and rear support plates 8, whether the flange at the rear side of the transmission mechanism 1 can continue to be transmitted can be controlled through the baffles 14. When the lowest height of the baffle 14 is lower than the height of the flange at the rear side, the flange at the rear side is blocked from continuing to be transmitted; when the lowest height of the baffle 14 is higher than the height of the flange at the rear side, the flange at the rear side can continue to be transmitted.

[0047] The sliding guide rail 16 is kept horizontally arranged. The sliding guide rail 16 is located above a row of support plates 8. The middle part of the sliding guide rail 16 is fixedly connected to the lower end of the rotating shaft connecting rod 15.

A linear motor 19 is respectively arranged on each sliding connection block 20, and the linear motor 19 is connected to the sliding guide rail 16. Through the mutual cooperation of the linear motor 19 and the sliding guide rail 16, the sliding connection block 20 is driven to slide on the sliding guide rail 16, so as to realize the mutual approach or mutual separation of the two sliding connection blocks 20, and further enable the detection mechanism 3 to be adapted to flanges with different outer diameters.

[0049] Two symmetrically arranged mounting grooves are provided on the sliding connection block 20, and the mounting grooves are vertically through.

[0052] A circular pressure sensor 34 is fixedly arranged at the inner opening of the mounting hole of the rotating roller 22. A top ball 23 is arranged at the outer opening of the mounting hole. A reset detection spring 33 is fixedly arranged between the top ball 23 and the pressure sensor 34. A flat groove is arranged at the outer end of the top ball 23. A connecting hole is arranged inside the top ball 23, and the connecting hole communicates with the flat groove. A connecting pipe 35 is arranged inside the connecting hole. The connecting pipe 35 passes through the reset detection spring 33 and the pressure sensor 34 and then communicates with the corresponding liquid discharge hole 30.

When the rubber pipe is not subject to external force, the rubber pipe is in a free relaxation state, and the multiple tooth-shaped baffles of the anti-leakage baffle 36 are joined to each other. At this time, the protective oil liquid inside the rubber pipe cannot seep out through the anti-leakage baffle 36. When the rubber pipe is bent by external force, the multiple tooth-shaped baffles on the anti-leakage baffle 36 are separated from each other. At this time, the protective oil liquid inside the rubber pipe can seep out to the outer adsorption sponge 32.

The fifth motor drives the tooth plate telescopic gear 47 to rotate, and the tooth plate telescopic gear 47 drives the arc-shaped tooth plate 46 to slide. When both arc-shaped tooth plates 46 extend to the outside of the installation connection box, the outer ends of the two arc-shaped tooth plates 46 are respectively clamped to one end of the hinge detection plate 39. At this time, the hinge detection plate 39 cannot rotate and is fixed to the horizontal state. When both arc-shaped tooth plates 46 extend into the installation connection box, the two arc-shaped tooth plates 46 no longer clamp one end of the hinge detection plate 39. At this time, the hinge detection plate 39 can rotate freely around the rotating shaft.

[0060] The working principle of the present invention is as follows:

[0061] Step 1: Place the flange on the support roller 6 of the transmission mechanism 1. The rotating support roller 6 drives the flange to move below the support flat plate. Then, control the second motor 11 to rotate. The second motor 11 drives two transverse transmission shafts to rotate synchronously through a T-shaped commutator. The two transverse transmission shafts drive two longitudinal transmission shafts to rotate synchronously through two SP-type commutators. The two longitudinal transmission shafts drive the screw jacks 12 on the left and right sides to act synchronously. The screws of all the screw jacks 12 rise synchronously, thereby driving all the support plates 8 to rise synchronously, and further driving the flange at the upper end of the support plate 8 to rise synchronously until the flange rises between the two sliding connection blocks 20.

[0062] Step 2: Control the hydraulic cylinders 9 on both sides to extend. The centering push plates 10 on both sides approach each other and gradually come into contact with the outer cylindrical surface of the flange. The flange is moved to directly below the detection mechanism 3 through the centering push plates 10 on both sides. Then, control the hydraulic cylinders 9 on both sides to contract, and the centering push plates 10 on both sides move away from the flange again.

[0063] Step 3: Control the third motor 24 to start. The third motor 24 drives the lifting screw 25 to rotate. Since the lifting sleeve 26 is screwed to the lifting screw 25, the lifting sleeve 26 is driven to lift and lower. The lifting sleeve 26 drives the liquid storage cylinder 27, the connecting sleeve 29, and the roller 22 to lift and lower synchronously, so that the height of the roller 22 corresponds to the height of the outer cylindrical surface of the flange. Then, control the linear motors 19 on the two sliding connection blocks 20 to start, driving the two sliding connection blocks 20 to approach each other on the sliding guide rails 16 until the rollers 22 of all the side-end face detection components 17 are in contact with the outer cylindrical surface of the flange, and at this time, the plane detection component 18 is located above the flange. During the process of the roller 22 coming into contact with the flange, the outer cylindrical surface of the flange squeezes the top block 31, the top block 31 squeezes the rubber tube, the rubber tube bends under the external force, and the multiple tooth-shaped gaskets on the leak-proof baffle 36 are separated from each other. At this time, the protective oil liquid inside the rubber tube can seep out through the leak-proof baffle 36 onto the outer adsorption sponge 32, and the protective oil liquid on the adsorption sponge 32 is smeared on the outer cylindrical surface of the flange, which can reduce the wear degree of the outer wall of the flange during the subsequent detection process.

[0064] Step 4: When the outer cylindrical surface of the flange presses against the top block 31, the top ball 23 is also subjected to a pressing force, which compresses the reset detection spring 33. The compression force of the reset detection spring 33 is transmitted to the pressure sensor 34, and the pressure sensor 34 receives a pressure signal. At this time, control the third motor 24 to rotate forward. The third motor 24 drives the lifting lead screw 25 to rotate forward. Since the lifting sleeve 26 is screwed to the lifting lead screw 25, the lifting sleeve 26 is driven to rise. The lifting sleeve 26 drives the liquid storage cylinder 27, the connecting sleeve 29, and the roller 22 to rise synchronously until the pressure sensor 34 on the uppermost side loses the pressure signal, and then stop rotating the third motor 24. Then control the third motor 24 to rotate in the reverse direction, thereby controlling the roller 22 to descend until the pressure sensor 34 on the lowermost side loses the pressure signal, and then stop rotating the third motor 24. By the process quantity of the reverse rotation of the third motor 24, the descending distance of the roller 22 can be known. Adding the distance between the pressure sensor 34 on the uppermost side and the pressure sensor 34 on the lowermost side, the thickness of the flange can be obtained.

[0065] Step 5: Control the third motor 24 to rotate again so that the height of the roller 22 corresponds to the height of the flange. At the same time, control the fourth motor to rotate. The fourth motor drives the transmission gear 40 to rotate. Since the transmission gear 40 meshes with the rack, the rack is driven to descend, and then the hinge connecting plate 38 is driven to descend inside the vertical groove. During the descent of the hinge connecting plate 38, both arc-shaped tooth plates 46 extend out of the installation connection box. The outer ends of both arc-shaped tooth plates 46 are respectively clamped with one end of the hinge detection plate 39. The hinge detection plate 39 cannot rotate and is fixed to the horizontal state, ensuring that the hinge detection plate 39 is always in the horizontal state during the descent of the hinge connecting plate 38 until the detection ball 42 at the lower end of the hinge detection plate 39 contacts the upper surface of the flange. At this time, the hinge connecting plate 38 stops descending. As the hinge detection plate 39 descends, the AI camera 41 on the hinge detection plate 39 is closer to the flange while adjusting the light intake, improving the detection accuracy of the upper surface of the flange and increasing the distance between the receiving detection plate 43 and the signal transmitter 45, thereby amplifying the detection data to improve the detection accuracy of the surface roughness. The cooperation between the hinge detection plate 39 and the detection ball 42 enables the detection ball 42 to abut against the surface of the flange.

[0066] Step 6: Control the rotation of the first motor 7. The first motor 7 drives the rotating shaft connecting rod 15 to rotate horizontally. The rotating shaft connecting rod 15 drives the sliding guide rail 16 to rotate horizontally. The sliding guide rail 16 drives the sliding connection blocks 20 on both sides to revolve around the rotating shaft connecting rod 15. The sliding connection blocks 20 drive a set of plane detection components 18 and two sets of side end face detection components 17 to revolve around the rotating shaft connecting rod 15. During the revolution of the side end face detection components 17, the roller 22 always maintains rolling contact with the outer cylindrical surface of the flange. The roller 22 drives the connecting sleeve 29 and the liquid storage cylinder 27 to rotate synchronously. The top block 31 on the roller 22 always contacts the outer cylindrical surface of the flange. The pressure sensor 34 can always detect the extrusion force of the outer cylindrical surface of the flange on the top ball 23, so as to obtain the change law of the pressure, and obtain the roughness of the outer cylindrical surface of the flange from the change law of the pressure. Through continuous adjustment of the third motor 24, the height of the roller 22 can be adjusted so that the roller 22 can detect all areas of the outer cylindrical surface of the flange.

[0067] Step 7: During the rotation of the first motor 7, control the rotation of the fifth motor so that when both arc-shaped toothed plates 46 extend into the installation connection box, the two arc-shaped toothed plates 46 no longer clamp one end of the hinged detection plate 39. At this time, the hinged detection plate 39 can rotate freely around the rotating shaft. During the horizontal rotation of the sliding guide rail 16 driven by the first motor 7, the hinged detection plate 39 fluctuates up and down, and the signal transmitter 45 at the upper end of the hinged detection plate 39 emits a fluctuation signal to the receiving detection plate 43. The receiving detection plate 43 collects the fluctuation signal, so as to detect the fluctuation change of the hinged detection plate 39 and realize the detection of the flatness roughness of the flange, and supplement the optical detection of the AI camera 41.

[0068] Step 8: Finally, control the roller 22 and the hinged detection plate 39 to rise and disengage from the flange. The lifting mechanism drives the support plate 8 to descend, so that the flange is placed back on the support roller 6, and the rotating support roller 6 moves the flange out of the detection area of the detection mechanism 3.

[0069] Step 9: Multiple sets of detection mechanisms can be set on the transmission mechanism 1. By adjusting the height of the baffle 14, it can be controlled whether the flange at the rear passes through the current detection mechanism, so that the flange can move to each set of detection mechanisms. When all the detection mechanisms are in working condition, the baffle 14 is used to block the flange from continuing to pass until a detection mechanism is idle, so as to ensure that each flange passes through the detection of the detection mechanism.
