Abstract

The invention discloses a micrometer caliper for measuring thickness. The micrometer caliper comprises a screw rod and a ruler base, the outer side of the screw rod is sleeved with a coarse adjustmentthreaded sleeve, one end of the screw rod is connected with a fine adjustment knob, the other end of the screw rod penetrates through the ruler base and is connected with a measuring shaft, one sideof the ruler base is connected with a detachable ruler frame through a pin, the bottom of the detachable ruler frame is connected with a measuring anvil, and the measuring anvil and the measuring shaft are arranged in the same direction. The micrometer caliper is flexible in structure, can be disassembled and assembled, and can select and install a proper ruler frame and a proper measuring anvil to measure the wall thickness of a product according to products of different structures. And meanwhile, a punching measurement mode is adopted, so that the wall thickness of a product with a closed structure can be measured, and the application range is wide.

Description

technical field [0001] The invention relates to the field of measuring instruments, in particular to a spiral micrometer for measuring thickness. Background technique [0002] Spiral micrometer, also known as micrometer, spiral micrometer, centimeter card, is a more precise tool for measuring length or thickness than vernier calipers. It can be accurate to 0.01mm and the measurement range is several centimeters. The existing spiral micrometer structure is one-piece fixed. It can only measure the thickness of products with simple structure and small size when using it to measure the thickness, and it is not flexible enough. measurement, the range of applications is limited. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a spiral micrometer for measuring thickness, which has a flexible and detachable structure, can measure the wall thickness of a closed structure, and expand...
