Description

Technical Field

[0001] The invention belongs to the technical field of flange detection, and in particular relates to a large-scale annular flange size detection device used in a processing line. Background Art

[0002] Large flanges are mainly used in large-diameter pipeline projects and are widely used in machinery, chemical industry, wind power and sewage treatment industries. Large flanges are usually made of low-alloy high-strength structural steel, such as S355NL steel. During the manufacturing process, the chemical composition and harmful element content of the steel ingot need to be strictly controlled to reduce the inclusion content and improve the density of the forgings; large annular flanges with a diameter of 3.5 meters to 8 meters are important parts that are essential for connecting wind turbine towers.

[0003] Existing large annular flanges are mostly inspected by manually operating a detection device and a clamping and rotating mechanism. This detection method takes a lot of time to clamp and place the workpiece, which reduces the detection efficiency and has high labor intensity. Existing assembly line detection is mostly used for automatic detection of small flanges. Due to their large size and weight, large annular flanges are prone to contact, wear or collision with other workpieces during production and transportation. Therefore, rapid detection of large annular flanges is very necessary. Through detection, it can be timely discovered whether the size of the product processed in the previous process on the assembly line is qualified, accurately control the quality of the product, and improve the product qualification rate. Since it is automatically detected on the production line, it also reduces the labor intensity, reduces the detection time, and improves production efficiency. Summary of the invention

The technical solutions of the present invention are described in detail below in conjunction with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0019] like Figure 1 As shown in FIG. 14 , the present invention provides a large-scale annular flange size detection device for a processing assembly line, comprising a transmission mechanism 1, wherein centering pushing mechanisms are symmetrically arranged on both sides of the middle part of the transmission mechanism 1, and each centering pushing mechanism includes a slidable centering pushing plate 10; a liftable support plate 8 is arranged in the middle part of the transmission mechanism 1 through a lifting mechanism, and the flange is supported by the support plate 8; a detection mechanism 3 is rotatably arranged above the middle part of the transmission mechanism 1, and the detection mechanism 3 includes a sliding guide rail 16, and two symmetrical sliding connecting blocks 20 are slidably arranged on the sliding guide rail 16, and each sliding connecting block 20 is provided with a group of plane detection components 18 and two groups of side end face detection components 17, the plane detection component 18 is located at the upper end of the flange, and the side end face detection component 17 is located on the outer side of the flange.

[0020] The transmission mechanism 1 includes a support base plate 5, a support seat, a support roller 6, and a synchronous transmission assembly. The support base plate 5 is a horizontally arranged square plate-shaped structure, on which a support seat is fixedly arranged, and a plurality of support rollers 6 are arranged equidistantly at the upper end of the support seat along the front-back direction, and the support rollers 6 are horizontally arranged along the left-right direction. The plurality of support rollers 6 are connected by a synchronous transmission assembly, so that all the support rollers 6 can rotate synchronously.

[0021] A support frame 2 is fixedly arranged in the middle of the support base plate 5, and the support frame 2 includes four support legs and a support plate. The support plate is a horizontally arranged square plate-shaped structure, and a vertical support leg is fixedly arranged at each of the four corners of the lower end surface of the support plate, and the lower ends of the four support legs are fixedly connected to the left and right edges of the middle of the support base plate 5. The support plate is located above the middle of the transmission mechanism 1, and a first motor 7 is fixedly arranged at the center of the upper end surface of the support plate, and the output shaft of the first motor 7 is vertically downward, and a vertical shaft connecting rod 15 is fixedly arranged on the output shaft of the first motor 7.

[0022] 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 alternately. A baffle plate 14 is fixedly arranged below the support plates 8 at the front and rear sides, respectively.

[0023] The centering push mechanism also 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 of the support base plate 5, and a hydraulic cylinder 9 is fixedly arranged on the upper end of the limit support platform 4. The piston rod of the hydraulic cylinder 9 is horizontally facing 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 structure.

[0024] The lifting mechanism includes a second motor 11, a screw lift 12, a bevel gear commutator 13, a transverse transmission shaft, and a longitudinal transmission shaft.

[0025] Two left and right screw lifts 12 are respectively arranged under each support plate 8. The screw lifts 12 are fixedly arranged on the support bottom plate 5. The upper end of the screw of the screw lifts 12 is fixedly sleeved with a jacking sleeve, and the jacking sleeve is rotatably arranged at the lower end surface of the support plate 8.

[0026] A second motor 11 is fixedly mounted on the upper end of the support base plate 5 , and an output shaft of the second motor 11 is arranged along the front-rear direction.

[0027] There are three bevel commutators 13, namely one T-type commutator and two SP-type commutators. The T-type commutator includes an input shaft and two left and right output shafts, and the SP-type commutator includes an input shaft and an output shaft that are perpendicular to each other.

[0028] The transverse transmission shaft is horizontally arranged along the left-right direction, and the longitudinal transmission 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, and a transverse transmission shaft is fixedly arranged at the two output shafts of the T-type commutator respectively, and the ends of the two transverse transmission shafts away from the T-type commutator are respectively fixedly connected to the input shafts of the two SP-type commutators, and a longitudinal transmission shaft is fixedly arranged at the output shafts of the two SP-type commutators respectively.

[0029] The second motor 11 drives the two lateral transmission shafts to rotate synchronously through the T-type commutator, and the two lateral transmission shafts drive the two longitudinal transmission shafts to rotate synchronously through the two SP-type commutators. The two longitudinal transmission shafts drive the screw lifts 12 on the left and right sides to move synchronously, and the screws of all the screw lifts 12 are synchronously lifted and lowered, thereby driving all the support plates 8 to rise and fall synchronously, and then driving the flanges on the upper ends of the support plates 8 to rise and fall synchronously. All the support plates 8 are lifted and lowered synchronously, thereby ensuring that the flanges are in a horizontal state, and no accidental tilting will occur to affect the detection of the detection mechanism 3.

[0030] When the support plate 8 rises, the two ends of the support plate 8 are separated from the support seat; when the support plate 8 is lowered to contact with the support seat, the support plate 8 is lowered to the lowest position. Since baffles 14 are fixedly provided at the lower ends of the support plates 8 at the front and rear ends, the baffles 14 can be used to control whether the flange on the rear side of the transmission mechanism 1 can continue to transmit. When the lowest height of the baffle 14 is lower than the height of the flange on the rear side, the flange on the rear side is blocked from continuing to transmit; when the lowest height of the baffle 14 is higher than the height of the flange on the rear side, the flange on the rear side can continue to transmit.

[0031] The sliding guide rail 16 is kept horizontally arranged, and is located above a row of support plates 8, and the middle 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 between 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 that the two sliding connection blocks 20 are moved closer to each other or farther away from each other, thereby making the detection mechanism 3 compatible with flanges of different outer diameters.

[0033] Two symmetrical mounting grooves are arranged on the sliding connection block 20 . The mounting grooves are connected vertically. A side end detection component 17 is arranged in each mounting groove. The side end detection component 17 includes a mounting shell 21 and a rotating roller 22 .

[0034] The installation shell 21 is a square cylindrical structure with an open lower end. A third motor 24 is fixedly arranged at the top of the interior of the installation shell 21. The output shaft of the third motor 24 is vertically downward. A vertical lifting screw 25 is fixedly arranged on the output shaft of the third motor 24. A lifting sleeve 26 is screwed on the outer side of the lifting screw 25. The lifting sleeve 26 is a vertically arranged square column structure. The outer side surface of the lifting sleeve 26 is in sliding contact with the inner wall of the installation shell 21. A liquid storage cylinder 27 is rotatably arranged at the lower end of the lifting sleeve 26. The liquid storage cylinder 27 stores protective oil.

[0037] Several leakage holes are evenly spaced on the side wall of the rubber tube, and each of the leakage holes is provided with a leak-proof baffle 36, which is composed of several tooth-shaped baffles abutting against each other. When the rubber tube is not subjected to external force, the rubber tube is in a free expansion state, and the multiple tooth-shaped baffles of the leak-proof baffle 36 are engaged with each other. At this time, the protective oil inside the rubber tube cannot seep out through the leak-proof baffle 36; when the rubber tube is bent by external force, the multiple tooth-shaped baffles on the leak-proof baffle 36 are separated from each other, and at this time, the protective oil inside the rubber tube can seep out through the leak-proof baffle 36 to the adsorption sponge 32 outside.

[0038] The model of the pressure sensor 34 is P3297. The pressure sensor 34 uses the piezoresistive effect. When the material is subjected to mechanical stress, its resistance value will change, so the pressure can be determined by measuring the change in resistance value.

The two transverse transmission shafts drive the two longitudinal transmission shafts to rotate synchronously through two SP-type commutators. The two longitudinal transmission shafts drive the screw lifts 12 on the left and right sides to move synchronously. The screws of all the screw lifts 12 rise synchronously, thereby driving all the support plates 8 to rise synchronously, and then driving the flange on the upper end of the support plate 8 to rise synchronously until the flange rises between the two sliding connection blocks 20.

[0045] Step 2: Control the hydraulic cylinders 9 on both sides to extend, and the centering push plates 10 on both sides approach each other and gradually contact the outer cylindrical surface of the flange, and move the flange to the bottom of the detection mechanism 3 through the centering push plates 10 on both sides. Then control the hydraulic cylinders 9 on both sides to retract, and the centering push plates 10 on both sides are away from the flange again.

[0046] Step 3, control the third motor 24 to start, the third motor 24 drives the lifting screw 25 to rotate, and since the lifting sleeve 26 is screwed to the lifting screw 25, the lifting sleeve 26 is driven to lift, and the lifting sleeve 26 drives the liquid storage cylinder 27, the connecting sleeve 29, and the roller 22 to rise and fall 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 rail 16, until the rollers 22 of all the side end 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 contact between the roller 22 and the flange, the outer cylindrical surface of the flange squeezes the top block 31, and the top block 31 squeezes the rubber tube. The rubber tube is bent by the external force, and the multiple toothed baffles on the leak-proof baffle 36 are separated from each other. At this time, the protective oil inside the rubber tube can seep through the leak-proof baffle 36 to the outer adsorption sponge 32, and the protective oil on the adsorption sponge 32 is smeared on the outer cylindrical surface of the flange, which can reduce the wear of the outer wall of the flange during subsequent inspection.

[0047] Step 4: When the outer cylindrical surface of the flange is pressed against the top block 31, the top ball 23 is also pressed and 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 the pressure signal. At this time, the third motor 24 is controlled to rotate forward, and the third motor 24 drives the lifting screw 25 to rotate forward. Since the lifting sleeve 26 is screwed with the lifting 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 the third motor 24 stops rotating. Then the third motor 24 is controlled to rotate in the opposite direction, thereby controlling the roller 22 to descend, and the third motor 24 stops rotating until the pressure sensor 34 on the lowermost side loses the pressure signal. The process quantity of the reverse rotation of the third motor 24 can be used to know the distance of the roller 22 descent, and the thickness of the flange can be obtained by adding the distance between the uppermost pressure sensor 34 and the lowermost pressure sensor 34.

[0048] 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, and the fourth motor drives the transmission gear 40 to rotate. Since the transmission gear 40 is meshed with the rack, the rack is driven to descend, and then the hinged connecting plate 38 is driven to descend inside the vertical groove. During the descent of the hinged connecting plate 38, the two arc-shaped toothed plates 46 are both extended to the outside of the installation connection box, and the outer ends of the two arc-shaped toothed plates 46 are respectively engaged with one end of the hinged detection plate 39, and the hinged detection plate 39 cannot rotate and is fixed to a horizontal state, ensuring that the hinged detection plate 39 is always in a horizontal state during the descent of the hinged connecting plate 38, until the detection ball 42 at the lower end of the hinged detection plate 39 contacts the upper end surface of the flange, at which time the hinged connecting plate 38 stops descending. As the hinged detection plate 39 descends, the AI ​​camera 41 on the hinged detection plate 39 adjusts the amount of light entering and moves closer to the flange, thereby improving the accuracy of the flange upper end surface detection and increasing the spacing between the receiving detection plate 43 and the signal transmitter 45, thereby amplifying the detection data to improve the accuracy of the surface roughness detection. The cooperation between the hinged detection plate 39 and the detection ball 42 enables the detection ball 42 to abut against the surface of the flange.

[0049] Step 6, control the first motor 7 to rotate, the first motor 7 drives the shaft connecting rod 15 to rotate horizontally, the 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 shaft connecting rod 15, and the sliding connection blocks 20 drive a set of plane detection components 18 and two sets of side end detection components 17 to revolve around the shaft connecting rod 15. During the process of the side end detection component 17 revolving, the roller 22 always keeps rolling contact with the outer cylindrical surface of the flange, and 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 is always in contact with the outer cylindrical surface of the flange, and 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 pressure change law, and the roughness of the outer cylindrical surface of the flange can be obtained from the pressure change law. By continuously adjusting the third motor 24 , the height of the rotating roller 22 can be adjusted, so that the rotating roller 22 can detect all areas of the outer cylindrical surface of the flange.

[0050] Step 7: During the rotation of the first motor 7, the fifth motor is controlled to rotate so that when both arc-shaped tooth plates 46 are inserted into the installation connection box, the two arc-shaped tooth plates 46 no longer clamp one end of the hinged detection plate 39, and the hinged detection plate 39 can rotate freely around the rotation axis. 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 sends a fluctuation signal to the receiving detection plate 43, and the receiving detection plate 43 collects the fluctuation signal, thereby detecting the fluctuation change of the hinged detection plate 39, realizing the detection of the flange surface roughness, and supplementing the optical detection of the AI ​​camera 41.

[0051] Step eight, finally control the rotating roller 22 and the hinged detection plate 39 to rise and separate from the flange, and the lifting mechanism drives the support plate 8 to descend, so that the flange is placed on the support roller 6 again, and is moved out of the detection area of ​​the detection mechanism 3 by the rotating support roller 6.

[0052] Step nine, multiple groups of detection mechanisms can be set on the transmission mechanism 1, and whether the rear flange passes through the current detection mechanism can be controlled by adjusting the height of the baffle 14, so that the flange can be moved to each group of detection mechanisms. When all the detection mechanisms are in working state, the baffle 14 is used to block the flange from continuing to pass until a detection mechanism is in an idle state, thereby ensuring that each flange is detected by the detection mechanism.
