Embodiment

[0020] The auxiliary device that the inventive method adopts, as figure 1 , 2 As shown, the upper part is horizontally opened with a chute that matches the shape of the caliper body, and the upper edge of the chute of the caliper is vertically provided with a locking screw hole, and a locking screw is connected to the locking screw hole; auxiliary device The lower part of the jaw is a claw, and a calibration plane perpendicular to the extending direction of the chute is processed on the jaw; a spherical calibration part is fixed on the calibration plane.

[0021] A kind of continuation verification method for the display value error of a large-scale universal caliper of the present invention, the specific verification method is as follows:

[0022] 1) Clamp the first standard gauge block with the measuring claws of the caliper, record the indicated value pointed to by the movable measuring claw when the caliper measures the first standard gauge block, and compare it with the ...

Abstract

The invention relates to a continuous verification method for the indication error of a large-range universal caliper, which belongs to the field of measurement verification. In the continuous verification method of the present invention, the first standard gauge block is measured by a caliper, and the position of the movable measuring claw of the caliper is locked after measurement; The spherical calibration part of the second standard gauge block is used as a continuous zero point to perform indication error verification, and the indication error is subtracted from the actual length of the two standard gauge blocks to obtain the error of the measurement indication at this point. The splicing verification method of the invention can realize the error verification of the indicated value labeling of a large-scale universal caliper.

Description

technical field [0001] The invention relates to a continuous verification method for the indication error of a large-range universal caliper, which belongs to the field of measurement verification. Background technique [0002] The caliper is a general tool used to measure the length of the product, and the accuracy of the caliper indication is an important prerequisite for the caliper to be able to measure accurately. The traditional process of caliper error verification is done by standard gauge blocks. At present, the longest standard gauge block that can guarantee accuracy is only 1000mm, and for large-scale general-purpose calipers, there is no more accurate error verification method for the error verification of the indication value above 1000mm, and only multiple The method of superimposing the standard gauge blocks will cause the error values ​​of multiple standard gauge blocks to accumulate, resulting in a large error in the measurement of the large-range general-p...
