Embodiment 1, as shown in fig. 1, this embodiment provides a method for implementing magnetic force control of an electronic angle indicator
Firstly, the rotary table 1 is rotatably disposed at a corresponding position of the magnetic sensor, and in this embodiment, the counterweight pendulum is disposed on the rotary table 1, so that when the fixed position of the rotary table 1 is inclined and changed, the counterweight pendulum drives the rotary table 1 to rotate under the condition of self emphasis.
Meanwhile, the magnetic substance is arranged at the position, corresponding to the Hall sensor head 2 of the magnetic sensor, on the turntable 1, because the turntable 1 is in a rotating state, and the Hall sensor head 2 is in a fixed state, for this reason, the position, corresponding to the Hall sensor head 2, on the whole turntable 1 can be an annular belt, and the magnetic substance is arranged on the annular belt.
Because the desk plate of the learning desk needs to be fixed at an angle suitable for learning, the magnetic substance needs to be distributed on the annular belt corresponding to the Hall sensing head 2 at intervals according to the inclination angle requirement, according to the adjustment angle of the existing learning desk, the range of about 12 degrees is the optimal writing inclination angle, the range of about 30 degrees is the optimal reading angle, and the range of about 40 degrees is the optimal drawing range. For this reason, in the present embodiment, there is no arrangement of the magnetic substance on the endless belts in positions of 12 °, 30 °, 40 °. Of course, according to the implementation of the present invention, in this embodiment, the magnetic substance gradually increases according to the gaussian value of the magnetic field strength in the clockwise direction, and of course, the magnetic substance may also gradually increase according to the gaussian value of the magnetic field strength in the reverse time direction, and only the scale corresponding to the pointer needs to be turned over.
In the present embodiment, the magnetic substance is a magnetic column 3, a peripheral hole 11 for placing the magnetic substance is provided on the turntable 1, and the height of the magnetic substance gradually increases in a clockwise direction or a counterclockwise direction. The purpose of setting in this way, when the magnetic columns 3 are the same in diameter and different in length, and obtain permanent magnetic force after being magnetized by the magnetizer, according to the principle of magnetic field related to physics, when the magnetic columns 3 are pressed into the through hole diameter around the turntable 1 from low to high in sequence, the distance between the tested magnetic field intensity point and the plane of the turntable 1 is unchanged, if the center hole of the turntable 1 is penetrated on the rotating shaft and rotates, and one magnetic field intensity test point is set at one point around the turntable 1, and the test point probe is close to the highest magnetic column 3, therefore, different magnetic columns 3 pass through the test point when the turntable 1 rotates due to different heights, and the magnetic field intensity from strong to weak or from weak to strong (when the turntable rotates) is obtained; if a Hall sensor or a magnetic sensor is arranged on the periphery of the turntable 1 and is electrified, the magnetic induction head is the same as the test point probe and is arranged close to the highest magnetic column 3, and the sensor can obtain intermittent output level signals.
Embodiment 2, as shown in fig. 2, this embodiment provides a method for implementing magnetic force control of an electronic angle indicator
Basically the same as the structure provided by the embodiment, except that in the embodiment, the length of the magnetic column 3 is the same, but the diameter of the magnetic column 3 is different, and the diameter of the magnetic column 3 is arranged in the order of increasing clockwise.
The magnetizing method is that the capacitor in the magnetizing machine is charged with DC high voltage and then discharged through a coil with very small resistance. The peak value of the discharge pulse current can reach tens of thousands of amperes. The current pulse generates a strong magnetic field in the coil, and the magnetic columns 3 with different diameters are gradually placed in the coil to be magnetized in the magnetic field, so that the permanent magnetization is realized instantly. According to the principle of magnetic field related to physics, the diameters of the magnetic columns 3 are increased from small to different, so that the same magnetization is obtained within the same magnetizing time, but the magnetic field intensity obtained by the magnetic columns 3 is different due to different diameters; when the magnetic columns 3 are pressed into the through holes at different peripheries of the rotary table 1, the periphery of the rotary table 1 obtains the magnetic field intensity from strong to weak or from weak to strong, if the central hole of the rotary table 1 penetrates through the rotary shaft and rotates, the periphery of the rotary table 1 generates a jumping magnetic field from strong to weak or from weak to strong, and if a Hall sensor or a magnetic sensor is arranged at the periphery of the rotary table 1 and is electrified, the sensor can obtain intermittent output level signals.
Embodiment 3, as shown in fig. 3, this embodiment provides a method for implementing magnetic force control of an electronic angle indicator
In this embodiment, the peripheral holes 11 are eliminated as compared with the embodiment 1 and the embodiment 2, and the magnetic substance is the screen printing oil 4 which is circularly arranged and is permeated with the magnetic ferrite magnetic powder, and the diameter of the screen printing oil 4 permeated with the magnetic ferrite magnetic powder is gradually increased in the clockwise direction.
During the concrete construction, press the silk screen printing plate on the plane of the rotary table 1 according to the circular pattern, and pour the silk screen printing oil which is well adjusted in advance and is permeated with the magnetic ferrite powder into the silk screen printing plate, slightly scraping the silk screen printing plate by a scraper, and pouring the circular pattern magnetic powder oil on the circumference of the rotary table 1, wherein the size is increased from small.
According to the principle of magnetic field related to physics, when the circular patterns are dried, the magnetic powder in each circular pattern generates weak magnetic field intensity, the inner patterns are different, and the quantity of the magnetic powder in the patterns is also different, so that the magnetic field intensity of the product is also different; if a Hall sensor or a magnetic sensor is arranged on the periphery of the turntable 1 and is electrified, the magnetic induction head of the sensor is arranged close to the peripheral plane of the turntable 1, then the magnetic powder in the pattern generates a weak magnetic field to generate action on the magnetic induction head, and the sensor can also obtain intermittent output level signals.
