Abstract

The invention relates to the technical field of radiation monitoring, and provides a hall device positioning device. The device comprises a rotating shaft, a magnetic steel installation base, magneticsteel, a plurality of hall devices, an upper adjusting ring, a lower adjusting ring and an installing seat, wherein the magnetic steel are installed in grooves of the magnetic steel installation base, the upper adjusting ring and the lower adjusting ring are used for installing the hall devices, the installing seat is connected with a shell; the hall devices are fixed in grooves of the upper adjusting ring and the lower adjusting ring and serves as the starting point and the end point of a angle response; the upper adjusting ring and the lower adjusting ring are installed on the installing seat in an overlapped mode, the upper adjusting ring and the lower adjusting ring can rotate in the installing seat; the magnetic steel installation base and the rotating shaft are coaxially fixed on the rotating shaft, and a shaft end of the rotating shaft penetrates through the upper adjusting ring and the lower adjusting ring. The device can conveniently realize angle positioning and feedback ofa rotating mechanism, so that a mounting process of angle positioning elements is simple and convenient, the positioning precision is improved, the angle position response to the hall devices can be changed at any time, and repeated utilization is realized.

Description

technical field [0001] The present application relates to the technical field of radiation monitoring, in particular to a Hall device positioning device. Background technique [0002] For rotary mechanisms, one of the methods usually used to achieve circumferential positioning is to use Hall device positioning. A common situation is to paste the magnetic steel on the rotating shaft, and paste the Hall device on the fixed housing close to the rotating shaft according to the required angle. When the magnetic steel on the rotating shaft rotates to the position aligned with or close to the fixed housing, the Hall The device responds, and the rotating mechanism stops rotating or realizes other predetermined actions after receiving the response. In the prior art, if the magnetic steel and the Hall device are generally directly fixed on the shaft and the housing, since it is difficult to measure the accurate response distance of the Hall device in advance, it is often found that t...
