Abstract

A clamping device used for measurement of thin plates comprises a device main body; the device main body comprises a proximate matter frame, a proximate matter frame fixing piece, a proximate matter frame corner connector, a guide rail, two slide blocks, pressing blocks, air cylinders and slide rods; the proximate matter frame takes the shape of a cuboid formed by connecting a plurality of pieces of proximate matter; the guide rail is fixed on the proximate matter in the front-back direction; the two slide blocks are arranged on the guide rail; the pressing blocks are fixed on the two slide blocks which are homodromous front and back; the air cylinders are mounted on the pressing blocks through air cylinder fixing seats at the bottoms of the pressing blocks, and two air cylinders are distributed on the same pressing block in the front-back direction; the slide rods are mounted on the inner surfaces of the pressing blocks. According to the invention, a thin plate is unfolded in a suspended and smooth manner without large-area contact type support, and then damage to the surface of the thin plate, caused by large-area contact type support, can be avoided to the greatest extent, so that professional clamping technology foundations are provided for improving the measurement of flatness, thickness and other shape features of the thin plate.

Description

technical field

[0001] The invention relates to a measuring device, in particular to a clamping device for thin plate shape measurement. Background technique

[0002] In the fields of surface mount technology (SMT), precision thin board manufacturing, etc., precision thin boards are manufactured or used in large quantities. For example, the stencil base material used in the surface mount industry, the material types involve stainless steel, nickel, nickel alloy, etc., the thickness is generally within 1mm, and in the process of its processing, it needs to go through electroforming, electroplating, polishing, etching, laser cutting And other processes, semi-finished products and final finished products in the middle need to be measured for thickness uniformity to ensure that the final product meets customer requirements; in terms of precision thin plate manufacturing, such as various stainless steels provided by large steel mills for the surface mount industry, etc. The pla...
