Abstract

The invention discloses a vernier caliper calibrating device. The calibrating device comprises a base, and further comprises a movable platform, a first clamp, a second clamp, an image acquisition device and a grating scale, wherein the movable platform is arranged on the base in a sliding manner; the first clamp is arranged on the movable platform, and is used for fixing the body of the vernier caliper; the second clamp is fixedly arranged on the base, and is used for fixing the vernier of the vernier caliper; the image acquisition device is fixedly arranged on the base, and is used for acquiring the scale images of the vernier caliper; the grating scale comprises an indicative grating and a scale grating; the indicative grating is fixed on the base; the scale grating is fixed on the movable platform. The calibrating device takes the grating scale with high precision to replace a standard gauge block for calibrating as calibrating standard; the precision of the vernier caliper calibrating device is improved; the whole calibrating process can be operated automatically; manual labor is saved; the calibrating efficiency is improved.

Description

technical field [0001] The invention relates to a verification device, in particular to a vernier caliper verification device. Background technique [0002] Vernier caliper (called caliper for short) is a measuring tool for measuring length, inner and outer diameter, and depth. The vernier caliper is composed of two parts, the main ruler and the sliding vernier attached to the main ruler. There are two sets of movable claws on the main scale and vernier of the vernier caliper, which are the inner measuring claw and the outer measuring claw. The inner measuring claw is usually used to measure the inner diameter, and the outer measuring claw is usually used to measure the length and outer diameter; the depth gauge and the vernier Connected together, you can measure the depth of the groove and cylinder. Commonly used vernier calipers can be divided into three types according to their accuracy: 0.1 mm, 0.05 mm and 0.02 mm vernier calipers. [0003] Vernier calipers are one of...
