Neodymium, iron and boron magnet plating shear force testing device

Abstract

The invention relates to a neodymium, iron and boron magnet plating shear force testing device which comprises a base, a transverse plate movement module and a vertical motor module. A control deviceand a display device are arranged on the base; the transverse plate movement module is arranged on the base and comprises a manual driving device, a transverse movement mechanism and a loading device,the transverse movement mechanism is connected with the manual driving device, the loading device is arranged on the transverse movement mechanism, and the loading device can be driven by the manualdriving via the transverse movement mechanism to move in the horizontal directions; the vertical motor module is arranged on the base and comprises an electric driving device and a pushing mechanism,the pushing mechanism is connected with the electric driving device and can be driven by the electric driving device to move at the constant speed in the vertical directions, and cross-axle movement can be formed by the constant-speed movement of the pushing mechanism in the vertical directions and the movement of the loading device in the horizontal directions, so that pressures can be applied tomagnets arranged on the loading device, and shear force on plating of the magnets can be tested. The neodymium, iron and boron magnet plating shear force testing device has the advantage that shear force on the plating of the neodymium, iron and boron magnets can be stably and accurately tested by the neodymium, iron and boron magnet plating shear force testing device.

Description

technical field [0001] The invention relates to the technical field of shear force testing devices, in particular to a shear force testing device for neodymium-iron-boron magnet coatings. Background technique [0002] NdFeB magnets are currently the permanent magnets with the strongest magnetic force. Their shapes can be processed according to specific requirements. However, their surfaces are prone to rust and usually require some protective surface treatment, such as copper plating, nickel plating, zinc plating, gold plating, Plated epoxy resin, etc. Coating performance is an important indicator of coating quality. [0003] At present, there is no device for testing the shear force of the NdFeB magnet coating on the market. In the NdFeB magnet production enterprises, the magnet is usually glued to the iron plate manually, and then a flat iron block is used to lean against it. , Hit it with a hammer, so the data cannot be measured, and it is often easy to break the edge o...
