Abstract

The invention discloses a measuring device for measuring the size of a plunger ring. The measuring device comprises a fixed base, a platform, two first measuring probes, a second measuring probe, anda measuring meter. The platform is installed on the fixed base by a platform adjusting screw for adjusting the front and rear positions of the platform. The two first measuring probes are arranged right above and right below the platform; and each first measuring probe is installed on the fixed base by using a longitudinal adjusting screw for adjusting the longitudinal position. The second measuring probe is installed on the fixed base at the left side or right side of the platform and the lateral position of the second measuring probe is adjusted by a first fine tuning screw connected to therear end. The measuring meter installed on the fixed base is connected with one first measuring probe and a second fine tuning screw is connected to the rear end of the other first measuring probe. According to the invention, the first measuring probes and the second measuring probe are used for replacing cylindrical heads for measurement; and on the basis of two-step calibration, a highest arc point and a largest external diameter point of the outer arc surface are determined, so that the measurement accuracy is ensured.

Description

technical field [0001] The invention relates to a measuring device for measuring the dimensions of a plunger ring and a method for using the same. Background technique [0002] It is often necessary to measure the outer diameter of the plunger ring during production and use. At present, the conventional method is to use a cylindrical head for measurement. When measuring, the reference plane of the plunger ring is often far away from the platform, which will lead to inaccurate measurement. At the same time, the plunger ring is not a conventional hollow cylindrical structure. It has an outer arc surface. The measurement of the outer diameter of the plunger ring must first determine the highest point of the outer arc surface. Neglect or encounter difficulty in finding the highest point of the arc, resulting in inaccurate measurements. Contents of the invention [0003] The purpose of the present invention is to provide a measuring device for measuring the size of the plunger...
