The electromagnetic impact device 30 is disposed on the base 10 and above the workpiece fixing device 20, and is used for impacting the workpiece for detection.

It can be appreciated that the electromagnetic impact device 30 can accelerate through the electromagnetic coil, so as to achieve the impact force caused by the speed required by higher height in the prior art, further reduce the height space required by the equipment, improve the application range of the equipment, and increase the adaptability of the equipment.

Referring to fig. 2, the electromagnetic impact device 30 includes an impact hammer 31, an acceleration assembly 32, and a fixing assembly 33.

The impact hammer 31 is accelerated by a magnetic field generated by energizing an acceleration coil 322 diffracted on the acceleration tube 321, and the impact speed required for the impact experiment is reached under the combined action of the acceleration of the electromagnetic field and the gravity. Thereby greatly reducing the length required for accelerating tube 321.

Referring to fig. 2 to 5, the acceleration assembly 32 further includes a reset coil 323, and the reset coil 323 is uniformly diffracted on the acceleration tube 321.

It should be noted that, in some embodiments of the present utility model, the reset coil 323 opposite to the magnetic field provided by the accelerating coil 322 is further included, and when the reset coil 323 is powered on, the impact hammer 31 can be automatically lifted and reset, so that manual reset is not needed, and labor intensity is reduced.

Referring to fig. 1, the electromagnetic fixing rod 332 is provided with a scale for adjusting the falling impact height of the impact hammer 31.

After the reset coil 323 drives the impact hammer 31 to rise, the electromagnetic fixing rod 332 is electrified to generate magnetic force, so that the impact hammer 31 can be adsorbed. The adjustment of the impact force can be accomplished by adjusting the height of the electromagnetic fixing rod 332 in the accelerating tube 321 or adjusting the intensity of the magnetic field generated by the accelerating coil 322.
