Abstract
The utility model relates to an inductance and built-in type electronic plug gauge with a double-flexible hinge, and more specifically, the utility model relates to a plug gauge used for measuring the hole diameter of mechanical components. The utility model has the advantages of simple structure, few size transferring links, high reliability and high measuring precision. The utility model has extensive application foreground in detection of the mechanical industry.
Description
The utility model relates to the built-in electronics feeler gauge of a kind of double-flexibility hinge inductance, the electronic plug gauge in specifically a kind of measurement mechanical part aperture.
The electronic plug gauge of producing both at home and abroad adopts the sensor of difference induction principle or differential transformer principle more at present, and inner structure has two types, and a kind of is single flexible hinge internal hidden type structure, and another kind is that small-sized pen type sensor is installed.It is complicated that this electronic plug gauge of two types, inner structure all seem, the pen type sensor especially is installed, and the size transmission link is many, adjusts difficulty, also has rubbing wear, influence serviceable life.
The purpose of this utility model is that proposition is a kind of simple in structure, the built-in electronics feeler gauge of double-flexibility hinge inductance of no rubbing wear.
Principle of work of the present utility model is: magnetic core and telefault directly are contained in the elastic body of a band double-flexibility hinge, the core component of having formed electronic plug gauge, by the double-flexibility hinged support, under two spring actions, two measuring staffs produce certain ergometry to the measured workpiece hole wall.The small difference in tested aperture has changed the position of magnetic core in telefault, thereby causes the variation of inductance value in the coil, obtains measurement result after handling through appliance circuit again.
Elaborate structure of the present utility model below in conjunction with accompanying drawing 1: after the steel spring plate thermal treatment of 8-10 millimeters thick as elastic body, and cut side's strip gab with wire cutting machine at its left end, circular place of opening and upper side leave the thickness of 0.25-0.3 millimeter, form first flexible hinge 6; In its upper right end-grain cutting one strip gab is arranged, circular place of opening and downside leave the thickness of 0.25-0.3 millimeter, form second flexible hinge 7, measuring staff 1,2 is installed in the upper and lower port of elastic body 9 left ends respectively, dynamometer spring 5 and 8 is installed in respectively in the hole at elastic body 9 top strip gabs and strip gab place, there is a circular hole at lower end middle part at elastic body 9 left ends, coil 4 is set in the circular hole, magnetic core 3 inserts in the coil 4, the upper end of magnetic core 3 is fixed on the upper end of elastic body 9, and magnetic core 3 and coil 4 have been formed difference induction formula sensor.
The utility model has reduced the size transmission link owing to simple in structure, has therefore improved measuring accuracy, strengthens reliability, has broad application prospects in mechanical industry detects.
Fig. 1 is a principle assumption diagram of the present utility model.
Embodiment:
Elastic body of the present utility model by the 65Mn spring steel after heat treatment processes with cutting machine, and magnetic core is processed into 2 millimeters of diameters with magnetic material, long 5 millimeters small cylinder, coil is formed by 0.06 millimeter copper cash coiling, 7 millimeters of its length, 5.5 millimeters of external diameters, measuring staff is with 45
#Steel is processed into screw shaped, studs with wimet in its termination and surveys ball.The utility model uses in Harbin Dongan Engine manufacturing company.
