Movable type loading device in any direction

Abstract

A movable type loading device in any direction comprises a circular arc guide rail, an outer slider and an inner slider, wherein a dovetail groove below the circular arc guide rail can ensure the circular arc guide rail to slide leftwards and rightwards; ball holes are arranged in a groove in the circular arc guide rail; four pressure spring balls on the inner slider can slide in the ball holes in the groove in the circular arc guide rail in a saltatory manner; the outer slider can slide on the circular arc guide rail and slide relative to the inner slider by fine-adjusting a screw rod, thus ensuring the outer slider to be precisely located in any direction between minus 90 degrees and plus 90 degrees; and a worm wheel, a worm and a force sensor are fixed on the outer slider. The device can load the test specimens, the load direction can be arbitrarily adjusted between minus 90 degrees and plus 90 degrees, simultaneously the load action point can horizontally move leftwards and rightwards and the load can be pressure or pull. The loading device can load the test specimens in different directions. The device has beautiful and concise structure and stable performance, is convenient to operate and use, can precisely determine the position and direction of the load and has wide practicability.

Description

technical field [0001] The invention relates to a loading device, in particular to a movable loading device in any direction suitable for experiments such as plane bending, oblique bending, bending-torsion combination and the like of beams. Background technique [0002] In the experiment of material mechanics, it is necessary to do the bending experiment of the cantilever beam. The existing loading device only has the one-way loading experimental device, and the loading direction of the device is unchanged. This type of loading device can generally only be used for plane bending experiments. For beams, there are mainly combined deformation forms such as oblique bending and bending torsion. The key to these experiments is to require that the load can change its orientation arbitrarily in a plane perpendicular to the beam. At present, there is no experimental device for bidirectional loading. To do a bidirectional loading experiment, two sets of loading devices must be instal...

Problems solved by technology

At present, there is no experimental device for two-way loading. To do two-way loading experiments, two sets of loading devices must be installed to cooperate with each other. The structure is complex, the operation is inconvenient, and the loading is not accurate.
