Magnetometer probe rotates auxiliary fixtures

Technical Field

The utility model relates to the technical field of magnetic influence measurement of civil aviation electronic equipment, in particular to a rotation auxiliary tool for a magnetometer probe.

Background

The DO-160 civil aviation magnetic influence test aims at finding the nearest distance between equipment which is allowed to be installed and a compass or a compass sensor, determining whether the equipment meets applicable equipment performance standards or assisting an installer in selecting the installation position of the equipment in an aircraft, and ensuring that the equipment normally operates in the aircraft without affecting nearby equipment.

In the test, the probe of the magnetic field intensity meter is firstly placed on a table, the probe of the magnetic field intensity meter is slowly pushed to rotate, when the number of the magnetic field intensity meter is between-10 nT and 10nT, the reading of the probe of the magnetic field intensity meter is hardly influenced by geomagnetic fields, and then the probe of the magnetic field intensity meter is stopped to rotate, so that the probe is kept still; and then gradually approaching the device to be tested to the magnetic field intensity meter probe, and measuring the minimum distance between the device and the magnetic field intensity meter probe when the magnetic field intensity meter reaches a certain specific value, and determining the distance between the device and the magnetic compass when the device is installed on an aircraft according to the distance.

In the technical scheme, firstly, a magnetometer probe is placed on a turntable, a larger rotation angle or more rotation turns are input into a speed reducing mechanism, and the input larger rotation quantity can be converted into smaller rotation angle output because the transmission ratio of the speed reducing mechanism is larger than 1, so that the turntable is driven to rotate in a small angle range, and the magnetometer probe is driven to rotate simultaneously when the turntable rotates; when the indicating value of the magnetometer is between-10 nT and 10nT, stopping inputting torque to the speed reducing mechanism, and stopping rotating the turntable; and then moving the equipment to be measured to approach the magnetometer probe, measuring the minimum distance between the equipment to be measured and the magnetometer probe at the moment when the magnetometer count reaches a certain specific value, and determining the installation position of the equipment to be measured on the aircraft according to the distance. The deflection adjustment of the magnetometer probe in the fine angle range is realized by utilizing the deceleration action of the deceleration mechanism, and compared with the mode of directly manually pushing the magnetometer probe to deflect, the magnetometer probe is easier to adjust in place, so that the test efficiency is improved.

Preferably, at least three guide wheels are arranged at the bottom of the turntable. The guide wheel can play a certain supporting role on the turntable, and meanwhile, the levelness of the turntable can be improved, so that the turntable can rotate more stably.

Preferably, the turntable is provided with a mounting groove for placing a magnetometer probe. After placing the magnetometer probe in the mounting groove, the turntable was rotated again to begin the test. The setting up the mounting groove can make the magnetometer probe stable on the carousel, prevents that the testers from touching magnetometer probe or other factors by mistake and leading to the magnetometer probe to drop from the carousel.

After the magnetometer is placed in the mounting groove, the magnetometer probe is clamped by the first clamping piece and the second clamping piece which simultaneously extend into the mounting groove, so that the magnetometer probe can be prevented from moving in the mounting groove or colliding with the inner wall of the mounting groove to influence the magnetometer indication.

Preferably, a first soft rubber block is arranged at one end of the first clamping piece, which is close to the second clamping piece, and a second soft rubber block is arranged at one end of the second clamping piece, which is close to the first clamping piece. Because the reading can be changed when the magnetometer probe receives larger pressure, the clamping force of the first clamping piece and the second clamping piece to the magnetometer probe is buffered by the first soft rubber block and the second soft rubber block, the reading error of the magnetometer is reduced, the magnetometer probe is protected from being clamped, meanwhile, the friction force to the magnetometer probe can be increased by the first soft rubber block and the second soft rubber block, and the magnetometer probe is more stable in the mounting groove.

The input shaft transmits the input torque to the intermediate shaft through the input gear, the intermediate shaft transmits the torque to the output shaft through the second gear, and finally the output shaft obtains the rotation quantity output of a smaller angle to be transmitted to the rotary disc through the meshing transmission of the input gear and the first gear and the meshing transmission of the second gear and the first gear, so that the rotary disc and the magnetometer deflect in a tiny angle range at the same time, and the fine adjustment of the deflection angle of the magnetometer probe is realized. The straight gear reduction mechanism composed of the base, the input gear, the input shaft, the first gear, the second gear, the intermediate shaft, the output gear and the output shaft is large in transmission ratio, stable in transmission ratio, simple in manufacturing and low in manufacturing cost.

Preferably, the device further comprises a manual ratchet, a swing rod, a first elastic piece and a second elastic piece; the manual ratchet wheel is coaxially connected with the input shaft; one end of the swing rod is rotationally connected with the base, and the other end of the swing rod is meshed with the ratchet wheel; the base is provided with a first elastic piece and a second elastic piece which are respectively fixedly arranged at the left side and the right side of the swing rod; one end of the first elastic piece is connected with one side of the swing rod, which is close to the first elastic piece, and one end of the second elastic piece is connected with the other side of the swing rod. The input shaft is driven to rotate by rotating the manual ratchet, when the manual ratchet rotates in one direction, one ratchet tooth on the manual ratchet pushes the swinging rod to rotate, the swinging rod tilts towards the direction of one elastic piece when rotating, and at the moment, the elastic piece is stressed and compressed; when the rotation of the manual ratchet wheel is stopped, the compressed elastic piece is deformed again to push the swing rod to reset; it will be appreciated that the manual ratchet may be rotated in both a clockwise and a counter-clockwise direction. Every time the manual ratchet wheel rotates the angle of a ratchet tooth, the carousel then rotates a less angle to the resistance to movement change of every ratchet tooth can be felt when the manual ratchet wheel is rotated to the test personnel, the rotation angle of carousel is favorable to finely tuning step by step, further improves experimental accuracy.

Preferably, scale marks are arranged on the turntable and the tray. Because the equipment that awaits measuring is being close to the in-process of magnetometer probe, the magnetometer probe probably drives the carousel and deflects together, leads to need readjusting the turned angle of carousel again when testing next equipment, and can make things convenient for the tester to remember the deflection condition of carousel when the magnetometer registration is qualified after setting up the scale mark to the zeroing of carousel resets, thereby reduces the time of adjusting carousel deflection angle when testing other equipment next time, improves test efficiency.

The utility model has the beneficial effects that: the rotating disc is utilized to drive the magnetometer probe to deflect, so that the stability of the deflection motion of the magnetometer probe can be improved; the output of a smaller rotation angle can be obtained by inputting a larger rotation angle or more rotation turns to the speed reducing mechanism by utilizing the speed reducing effect of the speed reducing mechanism, so that the fine adjustment of the deflection angle of the magnetometer probe is realized, and the test efficiency is improved; the test personnel can sense the movement resistance of each ratchet tooth when rotating the manual ratchet wheel, so that the deflection angle of the turntable is finely adjusted step by step, and the movement precision and test precision of the turntable can be improved.
