Straightness calibration device for V-shaped conveying roller way and using method thereof

Abstract

The invention relates to a straightness calibration device for a V-shaped conveying roller way. The straightness calibration device comprises a standard sample pipe, a standard frame, a hanger, a V-shaped piece and a stay wire steel wire. The standard frame comprises bases, vertical pipes and longitudinal rods, the bases are perpendicular in pairs, the bottom ends of the vertical pipes are perpendicularly connected with the bases, a plurality of observation holes are formed in the bottom ends of the vertical pipes, the top ends of the vertical pipes are perpendicularly connected with the longitudinal rods, the bottoms of the bases are conical surfaces matched with the conical surfaces of the V-shaped rollers, and inverted first U-shaped grooves are formed in the middles of the bottoms of the bases. Cross-shaped scales are arranged on the top surface of the base. The hanger is arranged in the vertical pipe and comprises a hanging cone and a hanging wire, the hanging cone is connected with a longitudinal rod located at the top end of the vertical pipe through the hanging wire, V-shaped pieces are arranged at the two ends of the longitudinal rod respectively, second U-shaped grooves are formed in the tops of the V-shaped pieces, and the connecting line of the groove bottom circle centers of the second U-shaped grooves of the V-shaped pieces at the two ends is parallel to the longitudinal rod. Straightness calibration is carried out on the conveying roller way composed of the multiple V-shaped rollers, and compared with the prior art, the calibration precision is improved.

Description

technical field [0001] The invention relates to the technical field of round bar flaw detection equipment, more specifically, it relates to a V-shaped conveying roller table flatness calibration device and its application method. Background technique [0002] The through-type automatic ultrasonic testing of round rods is a common round rod flaw detection technology. It is made by making the round rods advance through the flaw detection equipment on the conveying equipment, and at the same time, the ultrasonic probe in the ultrasonic flaw detection equipment rotates around the round rods to form ultrasonic waves. The spiral scanning of the round bar by the probe, the coupling water is filled between the probe and the round bar, the ultrasonic wave emitted by the probe enters the round bar through the coupling water, and then the echo data is detected to detect whether there are any unacceptable defects inside the round bar. That is to say, the automatic technology must be ins...

AI Technical Summary

Problems solved by technology

This technology can think that the center of the V-shaped roller is on a straight line within the error of ±0.5mm, but the error is still relatively large, and the underlying fundamental problem is that the levelness of the rotating shaft of each V-shaped roller and the alignment with the conveying direction cannot be guaranteed. Verticality, etc., cannot ensure that round bars of various specifications are conveyed smoothly on the conveying roller table

That is to say, the calibration accuracy of the straightness of the V-shaped roller conveying roller table in the prior art needs to be improved.
