Description

Clamp type deep bow thickness gauge

Technical Field

The utility model relates to the technical field of testing instruments, in particular to a clamp type deep bow thickness gauge.

Background

In the prior art, in the thickness measurement of various building partition boards and the thickness measurement of non-edge parts of plates, an inner caliper and an outer caliper are commonly used, and a certain distance from the edge parts is required to be used as thickness measurement points when the thickness of various partition boards and inorganic hard heat insulation products is measured. The measuring method of the external clamp matched with the vernier caliper quoted in the relevant standards is complex to operate, and the secondary measurement is easy to introduce artificial operation errors, so that the measuring result is inaccurate.

Taking the thickness measurement of the partition wall board as an example, the thickness measurement of the partition wall board requires that the thickness is measured at a position 100mm away from the edge part, and the thickness is measured by matching an external caliper with a vernier caliper. During measurement, the outer caliper is taken down after being clamped to a distance of 100mm, the distance between the jaws is measured by a vernier caliper to serve as a measured value, each plate measures six positions, the quantity of outgoing detection samples is different from 8 to 80 according to the batch range, and the quantity of the samples at the measuring point is 6 times that of the samples.

However, the measuring method of using the external caliper to match with the vernier caliper can increase the workload of a tester, and the external caliper is taken down from a measuring position, and the process of using the vernier caliper to measure the distance between the jaws introduces the artificial operation error of secondary measurement, thereby increasing the measurement error, and if the operation error is caused in the process of taking out the external caliper, the measurement error needs to be measured again, thereby increasing the difficulty of the measurement work and reducing the working efficiency.
