Abstract

The invention relates to a magnetic-railing-ruler-based portable flatness measurement instrument comprising a mechanical probe (7), a stepping motor (1), a magnetic railing ruler, and a pedestal (6). A support (5) is arranged at two ends of the pedestal (6); and the stepping motor (1) is installed at one end of the support (5). A lead screw guide rail (2) is arranged in the middle of the support (5); the stepping motor (1) and the lead screw guide rail (2) are connected; and a sliding block (3) is arranged on the lead screw guide rail (2). The magnetic railing ruler in an open type includes a magnetic stripe (8) and a magnetic head (9); and the magnetic railing ruler is installed at the outer surface of the sliding block (3). A fixation rack (4) is arranged on the sliding block (3); the probe (7) and the magnetic stripe (8) are fixed on the fixation rack (4) directly; the magnetic head (9) is arranged on the sliding block (3); and the magnetic head (9) and the probe (7) are embedded mutually. According to the invention, the measurement instrument can be carried to an experiment site conveniently; and flatness of the plane that can not be dismounted conveniently can be measured effectively and conveniently. The precision is high; and no reading or other difficult operation is required. The automation degree is high; and the position information and flatness information of the position can be obtained accurately.

Description

technical field [0001] The invention belongs to the technical field of flatness measurement, in particular to a portable flatness measuring instrument based on a magnetic scale. Background technique [0002] With the continuous development of science and technology in our country and the continuous transformation of the machinery industry, the requirements for measurement accuracy are getting higher and higher. The surface flatness of a plane is a common and very important measurement item in the industrial field. It has extensive and important applications for the positioning, installation and testing of various parts. Flatness means that the surface will not be absolutely flat when processing or producing industrial parts. The difference between the unevenness and absolute flatness is the flatness, which generally refers to the difference between the highest point and the lowest point between the wafer surface and the reference plane. The current flatness measuring instru...
