Abstract

The invention discloses a measuring device for measuring the flatness of a workpiece, and belongs to the technical field of flatness measurement. The measuring device comprises a bottom plate, a measuring assembly and three supporting column adjusting pieces. The measuring assembly comprises a measuring rod, a measuring piece and a side plate. Each supporting column adjusting piece comprises a sliding rod and at least one supporting column, the sliding rods are slidably arranged on the bottom plate, the sliding direction of the sliding rods is parallel to the plate face of the side plate, eachsupporting column comprises a universal supporting column and a special supporting column, the universal supporting columns are vertically arranged, and the bottom ends of the universal supporting columns are slidably inserted into the sliding rods in the axial direction of the sliding rods. The top ends of the universal supporting columns extend opposite to the bottom plate, the bottom end of the special supporting column is coaxially and detachably inserted into the top ends of the universal supporting columns, and the special supporting column is a rod piece with the adjustable length. Themeasuring device provided by the invention can be suitable for measuring the planeness of different workpieces to be measured.

Description

technical field [0001] The invention belongs to the technical field of flatness measurement, and more particularly relates to a measuring device for measuring the flatness of workpieces. Background technique [0002] After the die casting is processed, it needs to be tested for flatness to ensure the machining accuracy of the workpiece, so as to ensure the installation accuracy of the workpiece. [0003] In the related technology, firstly, three support columns of equal height are fixed on the bottom plate to support the workpiece to be measured, so as to ensure that the surface of the workpiece to be measured is arranged horizontally. Then, the flatness at different positions of the surface to be measured on the workpiece to be measured is respectively detected by using a dial gauge. [0004] However, the positions of the support points of different workpieces to be measured are different, and the thicknesses are different (the distance between the support point and the su...
