Gravity offset device for high-precision micrometer balls made of diamagnetic materials

Abstract

The invention discloses a gravity counteracting device with a high-precision micro-metering ball made of a diamagnetic material. The gravity counteracting device comprises an optical platform, a big-gradient strong magnetic field system and a strong magnetic field apparent gravity analysis device; the optical platform is provided with a three-dimensional displacement ball firing device; the three-dimensional displacement ball firing device comprises an upper three-dimensional displacement platform and a lower three-dimensional displacement platform, and the upper three-dimensional displacement platform and the lower three-dimensional displacement platform are fixedly connected through a detecting bracket to form an integral body; the upper three-dimensional displacement platform is fixedly provided with a pencil-shaped cylinder with a central hole; a diamagnetic material wire is inserted into the central hole of the pencil-shaped cylinder; the lower three-dimensional displacement platform is fixedly provided with an electric sparking plug; and the positions of the upper three-dimensional displacement platform and the lower three-dimensional displacement platform are adjusted to enable the electric sparking plug and the diamagnetic material wire to be located at the same axial line. As the magnetic force is utilized for generating a no-gravity environment, influence from the gravity to the eccentricity and roundness of the micro-metering ball in the process of firing the diamagnetic material micro-metering ball is accordingly reduced or removed.

Description

technical field [0001] The invention relates to the field of micro-nano measuring balls for three-coordinate measuring machines, in particular to a gravity offset device for preparing high-precision micro-measuring balls based on magnetizing diamagnetic materials. Background technique [0002] With the development of nano-processing technology, when the accuracy of micro-products increases, the demand for high-precision micro-3D measurement also increases accordingly. The most reliable way to measure the size, shape and spatial position of 3D parts is to use a spherical tail, contact probing system, such as a micro-nano CMM. In a touch probe, the most important component is the ball tip. A contact probe enables measurement of high aspect ratio micro-holes, grooves and sidewalls that are difficult to measure with non-contact probes. When the ball is manufactured by EDM, the tip of the fiber heats up and starts to melt, eventually forming a sphere. The larger the spherical ...

Problems solved by technology

Because the rotation method compensates for the eccentricity of the measuring ball, the coaxiality cannot be guaranteed, so the produced micro-metering ball does not meet the requirements of the coaxiality
