Device and method for measuring rotation angle and wave height of metal wire

Abstract

The invention discloses a device and a method for measuring a rotation angle and a wave height of a metal wire. One end of the measured metal wire is fixed on a rotation angle regulation disk and the other end of the measured metal wire passes through a flat-opening clamp and is connected with a forcemeter; a stretching force is applied to one end, connected with the forcemeter, of the measured wire, so that the measured metal wire is straightened; the flat-opening clamp clamps the measured metal wire tightly and releases the forcemeter; the rotation angle regulation disk is rotated to observe change of a waveform between any two points in a projection of the measured wire; when the first point reaches the wave crest, the degree of the rotation angle regulation disk is recorded; the rotation angle regulation disk is rotated according to the same direction, the degree of the rotation angle regulation disk is recorded when the second point reaches the wave crest; the rotation angle of the measured metal wire is calculated; and the wave height value of the measured metal wire in the projection is read. By the measurement device and the measurement method, the stretching force applied to the metal wire can be controlled effectively during measurement, and the rotation angle and the wave height can be measured precisely; and the device has a simple structure and is convenient to operate.

Description

technical field [0001] The invention relates to a testing device and method for the rotation angle of a wire, in particular to a measuring device and a measuring method for the rotation angle and wave height of a metal wire. Background technique [0002] In the division and slicing process of hard materials such as monocrystalline silicon and polycrystalline silicon in the field of electronics and solar energy, and gemstones in the LED field, the most used method is to use linear metal monofilaments to move in one direction or reciprocating under a certain tension. way to split slices. When the metal monofilament is moving, through the mortar transportation and injection system, before the metal monofilament contacts with the silicon rod and other objects to be cut, the mortar containing extremely hard abrasive particles is sprayed on the metal monofilament, and is cut by the metal monofilament belt. Through the continuous grinding process of extremely high hardness abrasiv...
