Detailed Description
The present invention will be described in further detail with reference to specific examples.
As shown in fig. 1 to 3, the utility model provides a controllable support of hardness tester magnetism, which comprises a base 1, a magnetic device 2 and a shifting piece 3; the top surface of the magnetic device 2 is a mounting surface for mounting a device to be tested. The magnetic device 2 is arranged inside the base 1, and the magnetic device 2 is demagnetized and electrified through the poking sheet 3; when making base 1 produce magnetism through stirring plectrum 3, can firmly adsorb fixedly part one end, guaranteed the complete level of face of detecting during the detection, surveyed a bit after, stir plectrum 3 and demagnetize, rotate or the translation part, stir 3 logical magnetic adsorption of plectrum again, test.
The top surface of base 1 is V profile or plane, and V type support angle does not have the regulation, can be big or small, generally is 45, and the bottom of V profile is provided with the recess for prevent stress concentration, and conveniently process the V profile, the less V type support then need not to set up the recess in general in-service use. The base 1 may be a cylinder, and the lower end thereof is provided with a mounting post 4. The base material can be 45 steel and other low alloy steel, and the cylinder of bottom and base 1 are integrative, are the position with the sclerometer cooperation, and the bottom cylinder inserts the interior fixing support of sclerometer.
The utility model provides a magnetic device 2 is current device, including iron core and winding outside the iron core and rather than power assorted conductive winding, conductive winding lug connection DC power supply or connect DC power supply through the current regulator.
