Twisting degree measurer for discrete holes

Abstract

The invention relates to a twisting degree measurer for discrete holes. The twisting degree measurer consists of a 'V'-shaped clamp, a locking mechanism and a digital inclinometer, wherein the lockingmechanism is vertically arranged in the center of the 'V'-shaped clamp; the digital inclinometer is horizontally arranged on one side of the 'V'-shaped clamp; the 'V'-shaped clamp consists of a basepart and dovetail-shaped locating parts; the dovetail-shaped locating parts are symmetrically connected below the base part and are integrated; two ends of the base part and two sides of the dovetail-shaped locating parts are of hollow structures; a 'V'-shaped groove is formed between the dovetail-shaped locating parts; the locking mechanism consists of a handle, an eccentric wheel, an eccentric connector, an upper expander, a lower expander, a dilator, a connection rod and a connection rod sleeve; the connection rod sleeve is arranged in the center of the base part; the connection rod is inserted into the connection rod sleeve; the upper end of the connection rod is connected with the eccentric connector, the eccentric wheel and the handle in sequence; the upper expander, the dilator andthe lower expander are arranged at the middle part and the lower part of the connection rod. The twisting degree measurer for the discrete holes is simple and ingenious in structure, firm in localization, accurate in measurement and innovative.

Description

technical field [0001] The invention belongs to the technical field of steel pipe processing equipment, in particular to a discontinuous hole torsion measuring instrument. Background technique [0002] Structural steel pipes, especially photovoltaic support pipes, in order to meet the requirements of mounting parts, often process a certain number of mounting holes on the surface of the steel pipes, and have high requirements for the torsion of the mounting holes. There are many ways to measure torsion, such as a general-purpose three-coordinate measuring instrument, and a digital inclinometer used to detect square pipes. The above-mentioned detection tools have disadvantages such as high cost, low efficiency, and poor versatility, especially for round steel pipes with discontinuous The batch torsion detection of holes cannot meet the fast, accurate and batch measurement. In order to more accurately and quickly detect the torsion of discontinuous installation holes of circul...
