Method for detecting deviation of mechanical center of clamping-type steel pipe conveying mechanism

Abstract

The invention discloses a method for detecting a deviation of a mechanical center of a clamping-type steel pipe conveying mechanism. The method comprises the following steps: putting a positioning flange into a positioning hole in the center of a clamping mechanism rack; feeding one end of a clamping sample pipe into the positioning flange in an alignment manner, and feeding the other end of the clamping sample pipe into a space between an upper clamping part and a lower clamping part in the clamping mechanism rack; enabling the upper clamping part and the lower clamping part to synchronously act, and clamping the clamping sample pipe in the center of each of the upper clamping part and the lower clamping part; putting detection flanges at two ends of the clamping sample pipe; enabling a thin steel wire to extend out of the mechanical center in an equipment process and penetrate through detection center holes of the detection flanges, and fixing the thin steel wire at two ends of the whole production unit; quickly detecting a mechanical center deviation value on two sides of the clamping mechanism rack through the detection flanges respectively for performing accurate mechanical adjustment. The detection method is simple and convenient to use and intuitive, has a hand feel, and can quickly detect and adjust the mechanical center of the clamping-type steel pipe conveying mechanism, thereby remarkably improving the detection efficiency.

Description

technical field [0001] The invention relates to a method for detecting and adjusting the mechanical center, in particular to a method for detecting and adjusting the mechanical center of a clamping steel pipe conveying mechanism. Background technique [0002] The clamping conveying mechanism usually refers to a mechanical mechanism that clamps workpieces and other objects forward or backward. The clamping conveying mechanism is widely used in steel pipe production process equipment, such as the second roller of the mandrel processing machine tool. Conveying mechanisms such as pinch, three-roller pinch for three-roller centering equipment, two-roller pinch for eddy current testing, and three-roller pinch for ultrasonic testing. [0003] As the equipment runs for a long time, the wear and looseness of parts will deteriorate the stability of the equipment, which will cause the technical indicators of the mechanical center to decline. The deviation of the mechanical center of t...
