Fig. 2 is a structure diagram of the utility model in an exploded state.
Description of reference numerals: 1-base, 2-detection panel, 3-back cover, 4-linear slide rail, 5-Hall element, 6-magnet, 7-adjusting bolt, 8-adjusting groove, 9-reset spring and 10-adjusting hole.
Detailed Description
The invention will be further described with reference to the embodiments shown in the drawings to which:
as shown in fig. 1 ~ 2, the utility model discloses mainly include base 1, detection panel 2 and hou gai 3, be equipped with linear slide rail 4 on the base 1, detection panel 2 passes through bottom slider sliding connection on linear slide rail 4.
The detection device is characterized in that a Hall element 5 is fixed on the base 1, a magnet 6 is arranged at the bottom of the detection panel 2, the magnet 6 faces the Hall element 5, when the detection panel 2 moves along a linear slide rail 4 on the base 1, the Hall element 5 and the magnet 6 are subjected to position change, a magnetic field is changed, and finally a digital signal is output and a position information value is read by a power meter.
Connect adjusting bolt 7 on magnet 6, adjusting bolt 7 passes through threaded connection and detects panel 2, and adjusting bolt 7 one end is equipped with adjusting groove 8, when using, stretches into adjusting groove 8 through the instrument, drives adjusting bolt 7 and rotates to required threshold region is transferred to the position of adjusting magnet 6.
The rear cover 3 is provided with an adjusting hole 10, the adjusting hole 10 faces the adjusting groove 8 of the adjusting bolt 7, and the adjusting hole 10 facilitates a screwdriver to extend into the adjusting groove 8 to adjust the adjusting bolt 7.
The utility model discloses a theory of operation is: when an object touches the front end of the detection panel, the detection panel overcomes the pressure of the return spring to move, so that the electric magnet moves towards the Hall element, the Hall element and the magnet are subjected to position change, the magnetic field changes, finally, a digital signal is output, the numerical value is read by the power meter, and the position information is known according to the change of the numerical value.
The utility model discloses simple structure, compactness, reasonable, job stabilization is reliable, and the position detection precision can reach mu level, and its structure is comparatively simple simultaneously, and the cost is lower, is fit for using widely on a large scale. The utility model discloses rely on high-accuracy magnet, high-accuracy hall element, base and detection panel to reach the testing result of high accuracy, the axis of guaranteeing close magnet and hall element's central point are concentric in the setting of linear slide rail, have guaranteed the degree of accuracy of testing result.
