A Small Aperture Magnet Measuring Field Tooling

Abstract

The invention discloses a small-diameter magnet measuring field tooling, which includes a hollow shaft, a positioning plate, a positioning plate bushing, an indexing pin, an indexing pin bracket and a probe positioning sleeve. The positioning plate is provided with a measuring field positioning hole. The measuring field positioning hole runs through both ends of the positioning disk, the hollow shaft passes through the measuring field positioning hole, and there are at least 3 pin holes arranged on the hollow shaft, and the pin holes are distributed at equal intervals along the axial direction of the hollow shaft. The positioning plate bushing is movably connected with the positioning plate, the indexing pin bracket is arranged on one end surface of the positioning plate, and the indexing pin bracket is provided with an indexing pin, the indexing pin is adapted to the pin hole, and the probe The positioning sleeve is arranged at one end of the hollow shaft. The invention has the advantages of simple structure, low cost and convenient use, can accurately locate multiple points, and is used for measuring and obtaining a large amount of data and analyzing the magnetic field distribution.

Description

technical field [0001] The invention relates to a superconducting magnet field measuring tool, in particular to a small aperture magnet measuring field tooling. Background technique [0002] The shimming tool is a necessary tool for the production of high-uniformity superconducting magnets, and is used to install the magnetic field size detection probe. Conventional manual measurement (such as Gauss meter) cannot be accurately positioned due to manual operation, the measurement error is large, and the measurement data is far from meeting the analysis accuracy; although the results of the three-dimensional magnetic field measurement system are accurate, the operation is very complicated and the cost is relatively high. high, low efficiency, and not suitable for daily use; and the existing measuring field tools are generally large in size, made of plastic or aluminum alloy, which can only adapt to the measuring field of large-aperture magnets, and cannot meet the needs of smal...

Conventional manual measurement (such as Gauss meter) cannot be accurately positioned due to manual operation, the measurement error is large, and the measurement data is far from meeting the analysis accuracy; although the results of the three-dimensional magnetic field measurement system are accurate, the operation is very complicated and the cost is relatively high. high, low efficiency, and not suitable for daily use; and the existing measuring field tools are generally large in size, made of plastic or aluminum alloy, which can only adapt to the measuring field of large-aperture magnets, and cannot meet the needs of small-aperture magnets. The centering method of aperture measuring field tools generally adopts the method of extending the legs to find the center of the magnet. It is self-evident that the error is large, and the measuring point cannot accurately reflect the magnetic field size of the actual position.
