High-accuracy floating electromagnet tensile force testing device and method thereof

Abstract

The invention discloses a high-accuracy floating electromagnet tensile force testing device and a method thereof. An electromagnet comprises a body and a floating armature positioned at one end of thebody; the high-accuracy floating electromagnet tensile force testing device comprises a bottom plate and a bearing table which is arranged on the bottom plate and used for bearing the body; a power-on assembly for powering on a coil in the body is arranged on the bearing table; a force servo assembly is arranged on the bottom plate; the force servo assembly is connected with the floating armatureby a buffer assembly so as to drive the floating armature to move in the direction of the central axis of the body. The high-accuracy floating electromagnet tensile force testing device has the mainbeneficial effects that: the high-accuracy floating electromagnet tensile force testing device is simple in structure and ingenious in design; the device can take a buffering effect on the force servoassembly, and thus, a problem of insufficiently accurate measured value caused by a higher pressure when the device just works or at the moment when the device completes working is avoided, and meanwhile, direct acting of an acting force on a pressure sensor can be avoided so as to greatly prolong the service life of the pressure sensor.

Description

technical field [0001] The invention relates to a tension testing device, in particular to a high-precision floating electromagnet tension testing device and a method thereof. Background technique [0002] In recent years, with the rapid development of the automobile industry, aviation industry, and shipbuilding industry, the demand for electromagnets, especially floating electromagnets, has gradually increased, and the requirements for performance indicators such as speed and electromagnetic force have become higher and higher.

Problems solved by technology

[0004] However, there is no buffer device in the above-mentioned invention, and the cylinder is directly connected to the sensor. The moment of work and the moment of completion of the work, its force is relatively large, resulting in inaccurate measurement data of the sensor and easy damage to the sensor.

In addition, whether there is a problem with the coil in the electromagnet cannot be detected directly. It needs to be detected by other detection coil detection devices. The operation process is cumbersome and affects work efficiency.
