A high-precision ball diameter measuring instrument

Abstract

The invention relates to a high-precision sphere diameter measuring instrument, which comprises a pulling-up device, a display device, a balance weight device and a measuring device, wherein the pulling-up device comprises clamp forceps, a vertical plate, a pulling plate, a screw rod and a connecting post, the balance weight device comprises a guide rail, a middle plate and a press block, the measuring device comprises a measuring head, a guide sleeve, a clamp seat and a sensor, the display device is used for displaying measuring results, the clamp forceps for towing the balance weight device are arranged on the pulling plate, the lower parts of the clamp forceps are connected with the screw rod passing through a middle through hole of the pulling plate, the connecting post is connected with a connecting screw rod through a screw nut and is connected with the upper part of the middle plate, the middle plate is towed to slide along the guide rail through the clamp forceps, the bottom of the vertical plate is fixedly arranged on the table top, and the top of the vertical plate fixedly supports the pull plate. The high-precision sphere diameter measuring instrument has the advantages that a display system, the balance weight device and a combined measuring head for sphere diameter measurement are organically combined, the requirements on the sizes of the measuring head, a standard workpiece and a guide sleeve as well as the matching relationship among the measuring head, the standard workpiece and the guide sleeve are extremely high, and the compact structure and the high precision of the whole sphere diameter measuring device are ensured.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a high-precision spherical diameter measuring instrument, which belongs to the application field of aerospace navigation.

[0002] Gyroscopes and accelerometers are key components in the navigation systems of satellites and rockets, among which the spherical structure gyroscopes and accelerometers used in gyroscopes and accelerometers are key components, so the accuracy of the spherical structure directly determines The accuracy of gyroscopes and accelerometers, in the production process of a certain type of navigation satellite, has a particularly high requirement for the accuracy of the spherical diameter. When using a traditional three-coordinate measuring instrument or a spherical diameter meter for measurement, due to the limitation of the accuracy of the equipment itself, there are problems when measuring the spherical diameter. very difficult

In this state at present, the use of traditional three-coordinate measuring instruments and spherometers is powerless in the face of ball diameters with high precision requirements.
