Problems solved by technology

Although the device can complete the entire verification process and reduce human operations, the device is too complicated, and the selection of standard values ​​still uses traditional gauge blocks. In the long-distance point verification process, it is necessary to splice multiple block gauges and only Scale part of the micrometer

Abstract

The invention discloses a micrometer automatic calibration device, which comprises a base; a mobile platform arranged on the base; a first clamp arranged on the base and used for fixing a microdrum of the micrometer; a second clamp arranged on the mobile platform and used for fixing a micrometer holder; a first information acquisition mechanism arranged on the base and used for collecting graduation line information of the micrometer; a second image acquisition mechanism arranged on the mobile platform and used for collecting light and shadow images of the micrometer; a rotating mechanism comprising a large rotating disk, a small rotating disk and a rotation motor, arranged on the base and used for driving the microdrum of the micrometer to rotate; and a grating ruler displacement sensor mechanism arranged at the right side of the base and comprising a scale grating, a support frame and an indication grating. The micrometer automatic calibration device utilizes a high-precision grating ruler displacement sensor, instead of a block gauge, to serve as a standard value of the calibration device, thereby improving accuracy of the calibration result, improving calibration work efficiency and improving automation degree of the calibration process.

Description

technical field [0001] The invention relates to a verification device, in particular to an automatic verification device for a micrometer. Background technique [0002] Micrometer, also known as screw micrometer, centicard, is a precision measuring tool used to measure length, which is more precise than vernier caliper. The micrometer is composed of an anvil, a micrometer screw, a ruler frame, a locking device, a heat insulation device, a fixed sleeve, a differential cylinder and a force measuring device. Micrometers are commonly used to measure the length and outer diameter of objects. At present, the accuracy of the micrometer can be accurate to one thousandth of a millimeter, and the last decimal place needs to be estimated. [0003] Micrometer is one of the most widely used measuring tools in high-precision processing and manufacturing. Its accuracy directly affects the dimensional accuracy of parts and the quality of products. At present, the verification of micromet...
