Description
Technical field
The present invention relates to a kind of position sensor, specifically a kind of detection accuracy can reach μ grades of position sensing
Device belongs to position sensor technical field.
Background technique
In the prior art, high-precision position measurement mainly uses Hall sensor or eddy current sensor.Hall sensor
The precision of detection can achieve mm grades, then high-precision position measurement request Hall sensor is unable to reach.And eddy current sensor
Although detection accuracy can reach μ grades, structure is complicated, at high cost.
Summary of the invention
It is an object of the present invention to overcome the above deficiencies, to provide a kind of position that detection accuracy can reach μ grades
Sensor is set, position detection accuracy can reach μ grades, while its structure is relatively simple, and cost is relatively low, suitable for large-scale promotion to make
With.
According to technical solution provided by the invention, a kind of detection accuracy can reach μ grades of position sensor include pedestal,
Detection panel and rear cover, it is characterized in that: pedestal is equipped with line slide rail, detection panel is slidably connected at straight line by base slider
On sliding rail；Hall element is fixed on the pedestal, detection panel bottom is equipped with magnet, and magnet is towards Hall element；The pedestal
Side removably connects rear cover by connector, is connected between rear cover and detection panel by reset spring.
Further, connection adjusts bolt on magnet, adjusts bolt and is connected through a screw thread detection panel, adjusts bolt one end
Equipped with regulating tank, covered after described equipped with adjustment hole, adjustment hole is towards the regulating tank for adjusting bolt.
Compared with the prior art the present invention has the advantage that
The invention has the advantages of simple structure, compactness and reasonable structure, stable and reliable in work, and position detection accuracy can reach μ grades, while its structure
Relatively simple, cost is relatively low, is suitable for large range promotion use.
Detailed description of the invention
Fig. 1 is perspective view of the present invention.
Fig. 2 is decomposing state structure chart of the present invention.
Description of symbols: 1- pedestal, 2- detection panel, 3- rear cover, 4- line slide rail, 5- Hall element, 6- magnet, 7-
Adjust bolt, 8- regulating tank, 9- reset spring, 10- adjustment hole.
Specific embodiment
The present invention will be further described in conjunction with the embodiment in attached drawing below:
As shown in Figure 1 and 2, the invention mainly comprises pedestal 1, detection panel 2 and rear cover 3, pedestal 1 is equipped with line slide rail 4, inspection
Panel 2 is surveyed to be slidably connected on line slide rail 4 by base slider.
Fix Hall element 5 on the pedestal 1,2 bottom of detection panel is equipped with magnet 6, magnet 6 towards Hall element 5, when
When detection panel 2 is moved along the line slide rail 4 on pedestal 1, shift in position occurs for Hall element 5 and magnet 6, and magnetic field generates change
Change, final output digital signal is by power meter read-out position information value.
1 side of pedestal removably connects rear cover 3 by connector, passes through reset between rear cover 3 and detection panel 2
Spring 9 connects, and reset spring 9 allows rear cover 3 and detection panel 2 to remain a certain distance.
Connection adjusts bolt 7 on the magnet 6, adjusts bolt 7 and is connected through a screw thread detection panel 2, adjusts 7 one end of bolt
It equipped with regulating tank 8, when in use, is protruded into regulating tank 8 by tool, drives and adjust the rotation of bolt 7, thus regulating magnet 6
Position, threshold values region required for being transferred to.
The rear cover 3 is equipped with adjustment hole 10, and adjustment hole 10 facilitates towards the regulating tank 8 for adjusting bolt 7, adjustment hole 10
Son protrudes into the adjusting that bolt 7 is adjusted in regulating tank 8.
The working principle of the invention is: when there is object to touch detection panel front end, detection panel will overcome reset spring
Pressure is mobile, so that motor magnet is mobile to Hall element, makes Hall element and magnet that shift in position occur, magnetic field generates change
Change, final output digital signal is by power meter readout value, we are according to the variation location aware information of numerical value.
The invention has the advantages of simple structure, compactness and reasonable structure, stable and reliable in work, and position detection accuracy can reach μ grades, while its
Structure is relatively simple, and cost is relatively low, is suitable for large range promotion use.The present invention relies on high-accuracy magnet, high-accuracy Hall
Element, pedestal and detection panel reach high-precision testing result, and the setting of line slide rail guarantees the axis and Hall of close magnet
The central point of element is with one heart, to ensure that the accuracy of testing result.
