The invention discloses a welding electrical contact high temperature resistance testing device which comprises a base, an outer tank, a heat insulation tank, heating devices, a cooling device, clamping devices, a collecting tank, a door plate, a control panel and a control system. The heat insulation tank is arranged in the outer tank; the heating devices are arranged on the inner walls of four sides of the heat insulation tank; heating devices include steam heating devices and electric heating devices; the cooling device is arranged above the heat insulation tank; the clamping devices are arranged in the middles of the inner walls of the two sides of the heat insulation tank; each clamping device comprises a rotating motor, a rotating shaft, a telescopic rod, an elastic rotating shaft and a clamping block; the collecting tank is arranged at the bottom of the heat insulation tank; the door plate is arranged on the heat insulation tank; the control panel is arranged on the outer tank,and the outer tank is arranged on the base. According to the invention, a tested workpiece can be uniformly heated, the temperature can be rapidly raised, the temperature can be accurately controlled,and the test result is more accurate.
Description
technical field [0001] The invention relates to a device for testing the high temperature resistance of a welding electric contact, which belongs to the technical field of testing equipment. Background technique [0002] Electric contacts are the core components of switching appliances, which are responsible for the work of connecting, breaking, and diverting electrical appliances. The key to excellent head performance is the development and preparation of new materials. After the electrical contacts are produced, they must go through the steps of high temperature testing. [0003] In the prior art, the heating device of the high temperature resistance detection device for electric contacts heats slowly, and there is no cooling device, which may cause danger when taking the electric contact after the test is completed, and most of the existing high temperature detection devices use The electrical contacts are prevented from being in the high-temperature detection tray, whi...
