[0015] Example

[0016] The technical scheme of the present invention will be further described below in conjunction with the drawings.

[0017] Such as figure 1 As shown, a low-energy compact high-current cyclotron magnetic field precision measurement device has an appearance of a turntable structure, including an upper rotating drive part, a middle rotating part and a lower rotating positioning part. The upper rotary driving part includes a stepping motor 1 and a drive shaft 2; the middle rotary part includes a swing arm 3 and a rotating track 4; the lower rotary positioning part includes a positioning shaft sleeve 5, a positioning shaft 6 and a precision angle encoder 7.

[0018] Such as figure 2 As shown, the connecting drive shaft 2 is sleeved with a hexagonal rotation connecting key 9 with a gap between the two, and the hexagonal rotation connecting key 9 and the swing arm 3 are rigidly connected. When the drive shaft 2 rotates, after the outer hexagon rotates through a cert...

Abstract

The invention discloses a device for measuring a magnetic field of a cyclotron. The device comprises a rotary driving part, a rotary part and a rotary positioning part, wherein a driving shaft is connected with a swing arm through a key; the rotary positioning part is positioned in the lower part of the rotary part; and the swing arm and a positioning shaft are in a rigid connection. The rotary driving part is separated from the rotary positioning part, so that a positioning component is not influenced by a driving connection gap, thereby reducing the circumference error of the rotary positioning system and improving the measurement accuracy of the magnetic field.

Description

technical field [0001] The invention belongs to the technical field of measuring magnetic variables, and in particular relates to a cyclotron magnetic field measuring device. Background technique [0002] The magnetic field is the most important component of a cyclotron. The magnetic field provides a binding force and a strong focusing force for the beam movement. The distribution of its field directly determines the performance of a cyclotron. In order to accurately measure the magnetic field distribution, at present, in the magnetic field measurement of low-energy cyclotrons, a manual magnetic measuring device with large gears for circumferential positioning is generally used, that is, a stepping motor drives a swing arm equipped with a magnetic measuring Hall plate. While rotating, it drives the rotating part of the angle encoder to rotate. Due to the backlash error in gear positioning and machining error due to the limitation of processing equipment during gear processi...
