Detailed Description
The following is a further detailed description of the embodiments:
reference numerals in the drawings of the specification include: the device comprises a base 1, a correction seat 2, a strip-shaped through hole 3, a limit column 4, a correction column 5, a sliding block 51, a hydraulic cylinder 6, a clamping groove 7, a clamping plate 8, a U-shaped bolt 9, a support bar 10 and a sliding groove 101.
The embodiment is basically as shown in fig. 1 and 2: the U-shaped bolt correcting device comprises a base 1 and a rectangular plate-shaped correcting seat 2, wherein a strip-shaped through hole 3 is formed in the middle of the correcting seat 2 along the length direction, supporting bars 10 are fixed at the bottoms of the correcting seats 2 on two sides of the strip-shaped through hole 3 through bolts, and the supporting bars 10 are fixed on the base 1 through bolts. The top bolt of the correction seat 2 on two sides of the strip-shaped through hole 3 is fixedly provided with a limit post 4, the limit post 4 is provided with two groups in the length direction of the strip-shaped through hole 3, each group comprises two limit posts 4 respectively positioned on two sides of the strip-shaped through hole 3, and the connecting line of the two limit posts 4 of each group is perpendicular to the strip-shaped through hole 3. The correction column 5 vertically penetrates through the strip-shaped through hole 3, a driving mechanism for driving the correction column 5 to translate in the strip-shaped through hole 3 is arranged on the base 1, the driving mechanism is a hydraulic cylinder 6 fixed on the base 1 through bolts, and the telescopic end of the hydraulic cylinder 6 is in threaded connection with the correction column 5. The side wall of the supporting bar 10 facing the bar-shaped through hole 3 is provided with a sliding groove 101 along the length direction, and the side end of the correcting column 5 is integrally formed with a sliding block 51 extending into the sliding groove 101.
The base 1 outside the correction seat 2 is detachably connected with a clamping plate 8 for detecting a U-shaped bolt 9 by bolts, and two clamping grooves 7 which are arranged side by side are formed in the clamping plate 8.
The specific implementation process is as follows: for the U-shaped bolt 9 to be corrected, a clamping plate 8 with a corresponding size is selected, the spacing between clamping grooves 7 on the clamping plate 8 is the same as the spacing between two ends of the U-shaped bolt 9, and the depths of the two clamping grooves 7 are the same. During correction, a worker holds the U-shaped bolt 9 and puts the U-shaped bolt 9 in the clamping groove 7 on the clamping plate 8 first to judge which deviation exists in the U-shaped bolt 9. Then, the hydraulic cylinder 6 is started, the hydraulic cylinder 6 drives the correction column 5 to transversely translate in the strip-shaped through hole 3, the U-shaped bolt 9 is placed between the limit column 4 and the correction column 5, the limit column 4 limits the U-shaped bolt 9, and the correction column 5 moves and extrudes the part to be corrected of the U-shaped bolt 9 to finish correction.
