[0023] See also Figure 3 The fixed structure includes: two fixed frames 8, a plurality of fixed telescopic rods 9, a plurality of fixed telescopic sleeves 10, a plurality of clamping springs 11, four limit plates 12 and two threaded nails 13; the two fixed frames 8 are respectively provided with threaded through holes and are connected to the inner wall surfaces of the two load-bearing telescopic shafts 7, the plurality of fixed telescopic rods 9 are respectively installed on the inner wall surfaces of the two fixed frames 8, the plurality of fixed telescopic sleeves 10 are respectively sleeved on the outer wall surfaces of the plurality of fixed telescopic rods 9, the plurality of clamping springs 11 are respectively sleeved on the outer wall surfaces of the plurality of fixed telescopic rods 9, the four limit plates 12 are respectively installed on the outer wall surfaces of the plurality of fixed telescopic sleeves 10, and the two threaded nails 13 are respectively installed in the threaded through holes respectively opened in the two fixed frames 8.

[0024] See also Figure 4 Two load-bearing telescopic frames 22 are installed on the upper wall of the straightening slide 14. In this embodiment, during straightening, the two load-bearing telescopic frames 22 are raised to a certain position to support the vicinity of the bent steel plate 23 to prevent damage to the pressure sensor 15. After straightening, the two load-bearing telescopic frames 22 are reset.

[0025] See also Figure 1 The inner wall surfaces of the two fixing frames 8 are installed with bent steel plates 23.

[0026] In this embodiment, the four limit plates 12 respectively drive the several fixed telescopic sleeves 10 to move along the several fixed telescopic rods 9, and the several clamping springs 11 contract, and the bent steel plate 23 is supported by the four limit plates 12. At this time, the horizontal and vertical displacements of the bent steel plate 23 are restricted, and then the operator tightens the two threaded nails 13 to fix the bent steel plate 23.

[0027] Specifically, the operator places the bent steel plate 23 on the two load-bearing telescopic frames 22, and then starts the two load-bearing telescopic shafts 7. The two load-bearing telescopic shafts 7 drive the two fixed frames 8 to move inward and sleeve the two ends of the bent steel plate 23. During this period, the four limit plates 12 respectively drive a number of fixed telescopic sleeves 10 to move along a number of fixed telescopic rods 9, and a number of clamping springs 11 contract. The bent steel plate 23 is held against by the four limit plates 12. At this time, the transverse and longitudinal displacements of the bent steel plate 23 are restricted. Then, the operator tightens the two threaded nails 13 to fix the bent steel plate 23. After that, the operator controls the two hydraulic rods 5 to drive the bent steel plate 23 to move downward until the bent steel plate 23 contacts the pulley 20, and drives the pressure sensing frame 18 to contact the pressure sensor 15 through the pulley 20. During this period, the pressure sensing frame 18 drives the straightening telescopic rod 17 to move downward along the straightening telescopic sleeve 16, and the return spring 24 contracts. At this time, the operator zeroes the pressure sensor 15 to prepare for the straightening work.

[0028] Embodiment 2, please refer to Figure 4 , the straightening structure includes: a straightening slide table 14, a pressure sensor 15, a straightening telescopic sleeve 16, a straightening telescopic rod 17, a pressure sensing frame 18, a wheel frame 19, a pulley 20 and a straightening device 21; the straightening slide table 14 is sleeved on the outer wall surfaces of the two slide rails 2 and is connected to the lead screw 4. The pressure sensor 15 is installed on the upper wall surface of the straightening slide table 14. The straightening telescopic sleeve 16 is installed on the upper wall surface of the straightening slide table 14. The straightening telescopic rod 17 is installed on the inner wall surface of the straightening telescopic sleeve 16. The pressure sensing frame 18 is fixed on the outer wall surface of the straightening telescopic rod 17. The wheel frame 19 is installed on the upper wall surface of the pressure sensing frame 18. The pulley 20 is sleeved on the outer wall surface of the wheel frame 19. The straightening device 21 is installed above the straightening slide table 14 and moves along with the straightening slide table 14.

[0029] Please refer to Figure 4 , a return spring 24 is sleeved on the outer wall surface of the straightening telescopic rod 17. In this embodiment, if the bent steel plate 23 bends downward, the pulley 20 drives the pressure sensing frame 18 to press downward, and the return spring 24 contracts.

[0030] In this embodiment, if the bent steel plate 23 bends downward, the pulley 20 drives the pressure sensing frame 18 to press downward, and the force on the pressure sensor 15 increases. At this time, the system starts to count. When the pressure of the pressure sensor 15 returns to zero again, the system calculates the position of the bent steel plate 23 corresponding to the intermediate value. Then, the straightening slide table 14 returns to the relative initial position. At the same time, the two hydraulic rods 5 lift the bent steel plate 23 through the two fixed frames 8. The two steering motors drive the bent steel plate 23 to rotate half a circle, and then descend to the initial position. Then, the straightening slide table 14 moves the same distance along the two slide rails 2 again. At this time, the steel plate 23 bends upward, and the detected value of the pressure sensor 15 is opposite. After the system calculates again, the straightening device 21 moves to the calculated position under the action of the system and presses down to straighten the bent steel plate 23.

[0031] Specifically, before installing the bent steel plate 23, the operator starts the lead screw 4 to drive the straightening slide table 14 to move along the two slide rails 2 to one end of the bearing seat 1. When starting to straighten, the operator starts the lead screw 4 again. The pulley 20 is driven by the straightening slide table 14 to move along the bent steel plate 23. If the bent steel plate 23 bends downward, the pulley 20 drives the pressure sensing frame 18 to press downward, the return spring 24 contracts, and the force on the pressure sensor 15 increases. At this time, the system starts to count. When the pressure of the pressure sensor 15 returns to zero again, the system calculates the position of the bent steel plate 23 corresponding to the intermediate value. Then the straightening slide table 14 returns to the relative initial position. At the same time, the two hydraulic rods 5 lift the bent steel plate 23 through the two fixing frames 8. The two steering motors drive the bent steel plate 23 to rotate half a circle, and then it descends to the initial position. Then the straightening slide table 14 moves the same distance along the two slide rails 2 again. At this time, the steel plate 23 bends upward, and the detected value of the pressure sensor 15 is opposite. After the system calculates again, the straightener 21 moves to the calculated position under the action of the system and presses down to straighten the bent steel plate 23. When straightening, the two bearing telescopic frames 22 rise to a certain position to support the vicinity of the bent steel plate 23 to prevent damage to the pressure sensor 15. After straightening, the two bearing telescopic frames 22 reset, and the straightening slide table 14 detects again, repeating the above work until the pressure value detected by the pressure sensor 15 is within the tolerance range.

[0032] The above has described in detail the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present invention.
