In the process of moving the correction clamping assemblies 8, the connecting pipe slides along the corresponding groove on the rotating shaft 18 through the guide block.

[0107] The interval adjusting assembly can drive the correction clamping assemblies 8 to clamp and correct the guide rail to be detected. Specifically, the two ends of the guide rail to be detected are placed on the corresponding end face support plates 802, and the second servo motor 19 drives the rotating shaft 18 to rotate, which drives the connecting pipe to rotate, so as to drive the second bevel gear 810 to rotate, and then drives the second bidirectional screw 804 fixed with the first bevel gear 805 to rotate, so that the correction clamping plate 807 can move along the first sliding rail 801 through the second sliding block 806, thereby clamping and correcting the guide rail to be detected.

[0108] After the guide rail to be detected is clamped, the upper surface of the guide rail is detected first. The detection assembly 14 is driven by the brake motor 1303 to rotate and placed in a vertical state. The second screw 1103 is driven to rotate by rotating the first adjusting knob 1104, which drives the height adjusting assembly 12 to move along the second sliding rail 1101 through the fourth sliding block 1202, thereby adjusting the front and back positions of the detection assembly 14. The connecting shaft 1205 is driven to rotate by rotating the second adjusting knob 1207, which drives the third screw 1203 to rotate through the transmission of the worm 1206 and the worm gear 1204, thereby driving the inclination adjusting assembly 13 to move along the first mounting bracket 1201 through the second mounting bracket 1301, so as to adjust the height of the detection assembly 14.

[0109] The detection assembly 14 is moved to the upper end of the guide rail to be detected, and then the detection assembly 14 is moved downward, so that the roller 1413 of the detection assembly 14 contacts the upper end of the guide rail, the second connecting plate 1411 rotates around the first fixed seat 1410, and the third connecting plate 1416 drives the sliding plate 1406 to move along the slide rod 1403 through the opening, thereby compressing the spring 1404.

[0110] The first screw 1002 is driven to rotate by the third servo motor 1004, which drives the longitudinal adjusting assembly to slide along the limiting rod 1003 through the third sliding block 1102, thereby driving the detection assembly 14 to move, so that the roller 1413 moves along the upper end of the guide rail. When the straightness of the upper end of the guide rail is defective, the sliding plate 1406 moves along the slide rod 1403.

[0111] When the guide rail side is detected, the detection assembly 14 is first driven to rotate by the brake motor 1303 to be in a horizontal state, then the position of the detection assembly 14 is adjusted by the height adjusting assembly 12 and the longitudinal displacement adjusting assembly 11, so that the roller 1413 of the detection assembly 14 is in contact with the side of the guide rail, and then the detection assembly 14 is driven to move by the transverse displacement adjusting assembly 10, so that the side of the guide rail can be detected;

[0112] When the sliding plate 1406 moves, the brush 1414 moves, the resistance wire 1419 on the outside of the ceramic rod 1418 is contacted by the brush 1414, and the resistance value in the circuit is changed with the movement of the brush 1414. The straightness can be detected by detecting the change of the current in the circuit. When the resistance in the circuit increases, the current decreases, and vice versa. The current can be detected by the oscilloscope connected in the circuit, and the change of the current is displayed on the operation panel.

[0113] And the distance between the laser receiver 1409 and the laser emitter 1408 also changes. Since the laser emission speed is constant, the time changes with the change of the distance. According to the emission and reception time between the laser receiver 1409 and the laser emitter 1408, the distance can be detected and displayed on the operation panel, so that the straightness of the guide rail can be further detected, and the detection error can be reduced.
