Technical Info
| The micrometer head can be divided into two types: mechanical micrometer, and electronic micrometer. Mechanical type is a micrometer head that measures the length of displacement through the thread principle. When used in platform, micrometer head has two functions, one is to generate displacement as the drive platform, and the other is to measure the reading in the displacement. The mechanical micrometer head is a micrometer adjustment device that measures the length using the thread principle and has a measurement resolution of up to the micron level with an accuracy of 0.01 mm.. Mechanical micrometer head is also called micrometer head, spiral micrometer, micrometer. In experiment, micrometer head is a tool used to generate displacement and indicate the amount of the displacement. The mounting sleeve of the micrometer head is to facilitate fixed mounting on the stand base. The main ruler on the axial sleeve has two rows of scale lines: the row that is marked with number is the whole millimeter line (1mm/grid); the other row is the half mm line (0.5mm/grid); the circumferential surface of the front part of the micrometer tube is engraved with 50 equal mark lines (0.01 mm/gird). When the micrometer tube or the fine focus knob is rotated by hand, the measuring rod advances or retreats along the direction of the axis. For every 1 gird rotated by the micrometer tube, the measuring rod moves a small displacement of 0.01 mm along the axial direction, which is also called the graduation value of the micrometer head. The micrometer head reading method is to read the scale value exposed on the main ruler of the sleeve first, pay attention to the half-millimeter line; then read the numerical value on the micrometer tube aligned with the horizontal line of the main ruler, and 1/10 graduation can be estimated. |
