Drop hammer impact testing machine

Abstract

The invention provides a drop hammer impact testing machine which is simple and practical in structure and can be used for conveniently measuring the depth of a hammer head which impacts into a sample. The drop hammer impact testing machine comprises a frame, a hammer lifting mechanism, a sample lifting mechanism, an electric appliance cabinet and a grating ruler, wherein the hammer lifting mechanism is arranged in the center on the upper part of the frame and comprises a pair of guide rods, an electromagnet sucker and a hammer body component; the hammer body component is movably connected with and positioned between the pair of guide rods; the sample lifting mechanism is arranged in the center of the lower part of the frame; the electric appliance cabinet is in transmission connection with the hammer component through a chain; the grating ruler is connected with the hammer component; the hammer component comprises a lifting block and a hammer lifting block; the lifting block is arranged above the hammer lifting block and is connected with the top surface of the electromagnet sucker; a proximity switch is arranged on the lifting block; a contact for triggering the proximity switch is arranged on the hammer lifting block. The impact depth of the sample is conveniently measured by the machine, and the operation is simple.

Description

technical field [0001] The present invention relates to testing equipment, in particular to the improvement of drop weight impact testing equipment. Background technique [0002] The existing drop hammer impact testing machine is manually operated. Each time the hammer head is manually hung on the hook, the hook is pulled up to the specified height, and then the hammer head is released, and the hammer head impacts the sample by its own weight to complete the impact test. . After a test, manually continue to place the sample on the workbench, and then continue to lift the hammer head for impact and reciprocating action, which consumes a lot of labor time, increases labor costs, and has low work efficiency. At the same time, the existing testing machine does not have the function of measuring the depth of the hammer penetrating into the sample, and cannot effectively analyze the performance of the sample in the form of data quantification.
