Problems solved by technology

When stretching a steel sample, the iron oxide scale on the surface of the steel sample will inevitably fall into the rotating mechanism of the universal testing machine table after falling off, which not only increases the probability of failure of the universal testing machine, but also affects the smooth progress of the experiment; The wear of the rotating parts of the testing machine will affect the lubrication effect and the accuracy of the test results, which will shorten the service life of the universal testing machine, increase the maintenance workload and increase the difficulty of maintenance

Abstract

The invention discloses a protective device for a universal testing machine, which comprises a base, a protective cover and a nut, the base, the protective cover and the nut are fixed and arranged sequentially from bottom to top, the protective cover is arranged in a cylindrical shape, and the Corresponding fixing screws are provided on the protective cover, more than one magnet is fixed on the nut, and more than one iron metal mesh is covered on the nut, and the structure of each iron mesh is matched. The iron metal mesh corresponds to a magnet, and the iron metal mesh is movably connected to the wire nut; the protective device of the universal testing machine is simple in operation, reasonable in structure, convenient to install and disassemble, and highly popular.

Description

technical field [0001] The invention relates to a protective device for a universal testing machine. Background technique [0002] According to the needs of metal performance inspection, the quality inspection departments of metallurgical factories are equipped with hydraulic multifunctional universal testing machines. During use, it was found that when the hydraulic universal testing machine is running, since the universal testing machine relies on the screw nut in the base and the screw drive connected to the lower worktable to realize the predetermined action, that is, the lower worktable passes through the rotating screw Complete the up and down movement with the screw nut in the fixed base, while the lead screw and screw nut of the transmission part are completely exposed outside. When stretching a steel sample, the iron oxide scale on the surface of the steel sample will inevitably fall into the rotating mechanism of the universal testing machine table after falling o...
