[0029] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 The C-shaped steel size measuring mechanism 1 includes a supporting base 4 and a C-shaped steel body 36. The inner top end of the supporting base 4 is evenly rotated and connected with a transport roller 8. The C-shaped steel body 36 is placed on the top of the transport roller 8. A second servo motor 7 is fixedly installed on the outer end of the supporting base 4.

Two first servo motors 6 are fixedly installed on the side of the supporting base 4 close to the second servo motor 7, and the two first servo motors 6 are symmetrically distributed on both sides of one of the transport rollers 8. The two first servo motors 6 are both located on the side of the PLC control panel 5 away from the second servo motor 7, and one of the first servo motors 6 is located in the middle of the outer side of the supporting base 4.

[0030] A double-threaded rod 14 is fixedly installed on the driving end of the first servo motor 6, and the two ends of the double-threaded rod 14 are rotatably connected to the support base 4 respectively. The two sides of the support base 4 are fixedly installed with limited sliding rods 13 respectively. The two limited sliding rods 13 are symmetrically slidably connected with movable brackets 15. The outside of the double-threaded rod 14 is provided with two groups of threads, and the two groups of threads are symmetrically arranged, and the movable bracket 15 is threadedly connected to the double-threaded rod 14. The symmetrically arranged threads can synchronize the two movable brackets 15 to move toward or in the opposite direction, and the two movable brackets 15 move toward each other and squeeze the C-shaped steel body 36 toward the middle through the relative movement of the two movable brackets 15, so as to achieve the fixed position of the C-shaped steel body 36. In order to facilitate the subsequent measurement of the C-shaped steel body 36, a mounting plate 16 is fixedly installed on one side of the top of the mobile bracket 15 close to the center of the supporting base 4, and an anti-collision plate 17 is fixedly installed on the side of the mounting plate 16 away from the mobile bracket 15. The anti-collision plate 17 reduces the damage to the C-shaped steel body 36 caused by extrusion, and a pressure sensor 18 is fixedly installed on the bottom end of the side of the anti-collision plate 17 away from the mounting plate 16.

[0031] A mounting frame 11 is fixedly installed at one end of the support base 4 away from the second servo motor 7, and a laser scanner 12 is fixedly installed on the inner side of the mounting frame 11. When the C-shaped steel body 36 moves to the inner side of the laser scanner 12, the laser scanner 12 emits lasers from four directions to the inside to measure and depict the outer side surface of the C-shaped steel body 36.

The infrared transmitter 9 and the infrared receiver 10 are symmetrically arranged. The infrared rays emitted by the infrared transmitter 9 are received by the infrared receiver 10. When the C-shaped steel body 36 moves to the infrared transmitter 9 and the infrared receiver 10, the infrared rays emitted by the infrared transmitter 9 are received by the infrared receiver 10. When the infrared receiver 10 is between the infrared receiver 10, the infrared receiver 10 cannot receive the infrared rays emitted by the infrared transmitter 9. At this time, the infrared receiver 10 transmits the signal to the PLC control panel 5, so as to detect the position of the C-shaped steel body 36. The infrared transmitter 9 and the infrared receiver 10 are located between the first servo motor 6 close to the mounting fixed frame 11 and the mounting fixed frame 11. The end of the transport roller 8 away from the second servo motor 7 is fixedly installed with a transmission gear 19.

All the transmission gears 19 are connected by the transmission chain 20, so that all the transmission gears 19 are driven to rotate through the transmission of the transmission chain 20 to drive the C-shaped steel body 36 to move.

[0032] See also Figure 2 and Figure 3The support base plate 21 is fixedly mounted on one end of the C-shaped steel size measuring mechanism 1 away from the second servo motor 7, and the support rod 23 is level with the side of the support base 4 close to the second servo motor 7, and the top of the support roller 26 is level with the top of the transport roller 8. When the transport roller 8 transports the C-shaped steel body 36 to move to the front end of the C-shaped steel body 36 and separates from the transport roller 8, the C-shaped steel body 36 moves to the top of the support roller 26. When the C-shaped steel body 36 is completely separated from the top of the transport roller 8, the C-shaped steel body 36 is transported to the top of the support roller 26 and the movement of the C-shaped steel body 36 is blocked by the baffle 25 to prevent the C-shaped steel body 36 from being The rolling support roller 26 conveys away from the top of the support frame 24, and the storage bin 27 is fixedly installed at the end of the support frame 24 away from the support rod 23. The top of the side of the support frame 24 away from the support rod 23 is in contact and connected with the bottom end of the limit block 29 away from the support cross bar 28. The telescopic end of the first electric hydraulic rod 22 pushes the side of the support frame 24 away from the support rod 23 to rotate upward, until the top of the end of the support frame 24 away from the support rod 23 is close to the bottom end of the limit block 29, the top of the support roller 26 is level with the top of the transport roller 8, which facilitates the transfer of the C-shaped steel body 36 from the top of the transport roller 8 to the top of the support roller 26.

[0033] The PLC control panel 5 is electrically connected to the first servo motor 6, the second servo motor 7, the infrared transmitter 9, the infrared receiver 10, the laser scanner 12, the pressure sensor 18, the first electric hydraulic rod 22 and the second electric hydraulic rod 35 respectively, and the control program is set through the PLC control panel 5 to control the automatic measurement operation.

[0034] Working principle: Before use, first set the control program through the PLC control panel 5, then make preparations, control the first servo motor 6 to start through the PLC control panel 5, and the driving end of the first servo motor 6 drives the double-headed threaded rod 14 to rotate. Since two sets of thread grooves are symmetrically provided on the double-headed threaded rod 14, and the movable bracket 15 is threadedly connected to the double-headed threaded rod 14, the rotating double-headed threaded rod 14 drives the movable bracket 15 to move toward the outside of the support base 4 until the movable bracket 15 is close to the inner side of the support base 4, and then the first electric hydraulic rod 22 is controlled to extend through the PLC control panel 5, and the first electric hydraulic rod 22 is extended. The telescopic end of the rod 22 pushes the support frame 24 to rotate upward away from the side of the support rod 23 until the top of the end of the support frame 24 away from the support rod 23 is close to the bottom end of the limit block 29. At this time, the support frame 24 rotates to a horizontal position, and the top of the support roller 26 is flush with the top of the transport roller 8. The second electric hydraulic rod 35 is controlled to retract through the PLC control panel 5, and the telescopic end of the second electric hydraulic rod 35 drives the support ear 34 to move downward. The movement of the support ear 34 drives the lifting fence 33 to slide downward on the inner side of the limiting slide groove 32 until the bottom end of the lifting fence 33 is close to the inner bottom end of the storage bin 27, completing the preparation for measurement.

[0035] During measurement, the C-shaped steel body 36 is placed on the top of the transport roller 8 by external force, and then the measurement program is started through the PLC control panel 5. The PLC control panel 5 controls the second servo motor 7, the infrared transmitter 9, the infrared receiver 10 and the laser scanner 12 to start. The infrared transmitter 9 emits infrared rays, and the infrared receiver 10 receives the infrared rays emitted by the infrared transmitter 9. The driving end of the second servo motor 7 drives the transport roller 8 installed at the driving end of the second servo motor 7 to rotate. The rotating transport roller 8 drives the transmission gear 19 to rotate. The rotating transmission gear 19 is driven by the transmission chain 2. 0 drives all other transmission gears 19 to rotate, and the remaining transmission gears 19 drive the transport rollers 8 connected to them to rotate, thereby driving all the transport rollers 8 to rotate, and the rotating transport rollers 8 drive the C-shaped steel body 36 at the top of the transport roller 8 to move closer to the laser scanner 12. When the front end of the C-shaped steel body 36 moves between the infrared transmitter 9 and the infrared receiver 10, the infrared rays are blocked by the C-shaped steel body 36, and the infrared receiver 10 cannot receive the infrared rays emitted by the infrared transmitter 9. The infrared receiver 10 transmits the signal to the PLC control panel 5 in real time. At this time, the PLC control The control panel 5 controls the second servo motor 7 to turn off, and at the same time controls the first servo motor 6 to start positioning the C-shaped steel body 36. The driving end of the first servo motor 6 drives the double-headed threaded rod 14 to rotate, and the rotating double-headed threaded rod 14 drives the movable brackets 15 at both ends to move toward the middle. The movement of the movable bracket 15 drives the mounting plate 16 to move, and the movement of the mounting plate 16 drives the anti-collision plate 17 and the pressure sensor 18 to move closer to the C-shaped steel body 36, until the side of the anti-collision plate 17 away from the mounting plate 16 contacts the outer side of the C-shaped steel body 36, and the anti-collision plates 17 located on both sides of the C-shaped steel body 36 are moved closer to the C-shaped steel body 36. 7 push the C-shaped steel body 36 to move toward the middle, and the pressure sensor 18 detects the pressure when it contacts the outer side of the C-shaped steel body 36, and transmits the pressure to the PLC control panel 5 in real time. When the C-shaped steel body 36 is successfully positioned in the middle of the transport roller 8 and is in a vertical cross state with the transport roller 8, the pressure on the pressure sensor 18 increases. When the pressure reaches a predetermined value, the PLC control panel 5 controls the first servo motor 6 to rotate in the opposite direction to drive the two movable brackets 15 to move away from the C-shaped steel body 36, until the movable brackets 15 move to the inner side of the support base 4.

[0036] After the C-shaped steel body 36 is positioned successfully, the PLC control panel 5 controls the second servo motor 7 to continue to start, and the second servo motor 7 drives the transport roller 8 to rotate, thereby driving the C-shaped steel body 36 to continue to move in the direction of the laser scanner 12. The started laser scanner 12 emits a laser to the inside to start scanning. When the C-shaped steel body 36 moves to the inside of the laser scanner 12, the laser scanner 12 performs a full-scale scan on the outer side of the C-shaped steel body 36, and the laser scanner 12 transmits the scanning data to the PLC control panel 5 in real time. The transport roller 8 continues to transport the C-shaped steel body 36 through the inside of the laser scanner 12. When the front end of the C-shaped steel body 36 is separated from the transport roller 8, the C-shaped steel body 36 moves to the top of the support roller 26. When the C-shaped steel body 36 is completely separated from the top of the transport roller 8, the C-shaped steel body 36 is transported to the top of the support roller 26 and the movement of the C-shaped steel body 36 is blocked by the baffle 25 to prevent the C-shaped steel body 36 from being transported away from the top of the support frame 24 by the rolling support roller 26, and then the PLC control panel The plate 5 controls the first electric hydraulic rod 22 to retract, and the telescopic end of the first electric hydraulic rod 22 drives the support frame 24 to rotate downward. The rotation of the support frame 24 drives the support roller 26 to tilt downward away from the end of the support rod 23. When the support roller 26 tilts downward, the C-shaped steel body 36 slides downward on the top of the support roller 26 under the action of gravity. The C-shaped steel body 36 slides downward to the top of the support roller 26 and falls on the top of the guide bracket 31. Since the guide bracket 31 is designed to be inclined, the C-shaped steel body 36 falls on the top of the guide bracket 31. The C-shaped steel body 36 continues to slide close to the lifting fence 33 until the C-shaped steel body 36 slides to the inner bottom end of the storage bin 27. When the C-shaped steel body 36 inside the storage bin 27 is full, the second electric hydraulic rod 35 is controlled to extend through the PLC control panel 5. The telescopic end of the second electric hydraulic rod 35 pushes the supporting ear 34 to move upward. The movement of the supporting ear 34 drives the lifting fence 33 to slide upward to the top on the inner side of the limiting slide groove 32, and then the C-shaped steel body 36 inside the storage bin 27 can be taken out by external force.
