Abstract

The invention discloses a calibration apparatus which comprises an electronic vernier caliper and a movable clamping part. The electronic vernier caliper comprises a rule rod and a vernier which can move longitudinally along the rule rod, and the vernier is provided with a display screen which is used for displaying the movement distance of the vernier along the rule rod. The movable clamping part is used for clamping one end of a wire to be measured and is fixedly connected with the vernier. According to the invention, the calibration apparatus adopts the movable clamping part, when the movable clamping part carries one end of the wire to be measured and moves along the rule rod of the vernier, the display screen of the vernier displays the corresponding data, so the measurement process is greatly simplified and the calibration precision of a soft wire is ensured. A hand wheel is adopted as the power source of a power mechanism of the calibration apparatus, a pair of conical gears is taken as the transmission mechanism, and a nut which can move longitudinally relative to a screw rod drives the movable clamping part to move, so strict linear relation between the movement amount of the movable clamping part and the variation quantity of the vernier is realized. The calibration apparatus has the advantages of good measurement precision and simple structure.

Description

technical field [0001] The invention relates to a calibration instrument. Background technique [0002] The vernier caliper is a frequently used calibration instrument, especially the electronic vernier caliper greatly simplifies the process of data reading, with high measurement accuracy and fast measurement speed. However, the use of vernier calipers still has inconveniences. For objects to be measured with rigid materials, the measurement process of vernier calipers is relatively simple; but for objects to be measured with soft materials, if there is no good tool assistance during measurement, so that the object to be measured can be fully expanded, the measurement accuracy will be poor. . In actual work, the method of manual pulling is usually used to fully unfold the object to be measured, and then the measuring personnel will operate it. This process is relatively cumbersome, which affects the efficiency of the measurement. Contents of the invention [0003] Aimi...
