Description

Technical Field

[0001] The invention belongs to the technical field of parallelism measurement, and more specifically, particularly relates to a portable parallelism measuring device. Background Art

[0002] Parallelism measurement refers to measuring the degree of parallelism between two planes or two straight lines. Parallelism evaluates the parallel state between straight lines, between planes, or between a straight line and a plane. The dial indicator is a universal length measuring tool made of a precision rack and pinion mechanism, commonly used to measure the position error of a workpiece, including parallelism error. The dial indicator uses a tiny movement of the measuring rod, which is amplified by the gear transmission and converted into the rotation of the pointer on the dial, thereby reading the size of the measured dimension. Its graduation value is 0.01 mm, that is, the measurement accuracy can reach two decimal places.

[0003] The parallelism measuring devices currently used still have the following problems:

[0004] 1. In order to improve the portability of the parallelism measuring device, the parallelism measuring range is short and it is impossible to measure a longer workpiece; it is impossible to increase the measuring length of the workpiece while ensuring portability;

[0005] 2. The workpiece to be measured is usually placed on a platform, and it is impossible to automatically fix the workpiece to be measured before measurement, which makes the workpiece easy to move;
