Abstract

The invention discloses a device for measuring radius of a spherical crown and a measuring method thereof. The device comprises an outer measuring rod (1), an inner measuring rod (2), a dial indicator (4) and a standard block (3), wherein the inner measuring rod (2) is arranged inside the outer measuring rod (1), and contacts with the surface of the measured spherical crown by a measuring rod outer circle or an inner hole; and the standard block (4) is added by the dial indicator (4) to read out the end surface fall of two measuring rods; and then the radius of the measured workpiece is calculated. The device has a very simple structure, convenience in use and high measuring precision.

Description

technical field [0001] The invention relates to a device for measuring the radius of a spherical cap, and also relates to a method for measuring the radius of a spherical cap with the measuring device being convenient to use and high in measurement accuracy. Background technique [0002] In the process of industrial production and product maintenance, it is often necessary to measure the spherical radius of some spherical products. For example, concrete delivery pump swing cylinder ball socket, oil cylinder ball head, internal combustion engine nozzle oil pump roller pin. Since the spherical cap is smaller than a hemisphere, and the central angle corresponding to any arc on its surface is less than 180°, it is difficult to measure the radius of the spherical cap with conventional measuring tools. The arc caliper currently sold in the market is mainly suitable for measuring the arc radius of a cylinder. Someone has modified a vernier caliper for measuring the radius, but the...
