Abstract

The invention provides ball seat inner size measurement equipment. The ball seat inner size measurement equipment comprises a measurement tool and a dial indicator arranged thereon, the measurement tool can be used for placing the ball seat and mechanically transmitting a ball seat inner circle size measurement result to the dial indicator; since one inner circle is fixed by adopting three points,a measurement rod is placed between two support rods capable of moving tiny; on the basis of positioning the inner circle, the measurement rod and the dial indicator can be protected more conveniently.

Description

technical field [0001] The invention belongs to the field of measurement and detection. In particular, it relates to a measuring tool for measuring the diameter of an inner spherical surface within a certain distance from an end surface. Background technique [0002] A dial gauge is a length measuring instrument that converts general linear displacement (linear motion) into rotational motion of a pointer through gears or levers, and then reads on the dial. Dial gauges are widely used indicating measuring tools in precision measurement. It is a comparative measuring tool and can only measure relative values, not absolute values. It is mainly used to check the shape and position error of the workpiece. (such as roundness, flatness, verticality, circular runout, etc.), and is also commonly used for precision alignment of workpieces. The application of the dial indicator is various, and the fixture of the workpiece to be measured is generally set according to the actual need...
