Problems solved by technology

The whole process is time-consuming and labor-intensive, and the positioning may be inaccurate due to manual flipping of the electromagnetic driver, which may cause internal stress in the connection between the electromagnetic driver and the vibration table, causing the excitation direction to shift during the vibration test and affecting the vibration test results.

Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0021] A positioning and locking device for a vibration simulation table, comprising: a rotatable turntable 3 and a positioning thimble; a groove is formed on the side of the turntable 3, and when the positioning thimble abuts against the groove, the turntable is locked; when the positioning thimble Unlock the turntable when moving away from the groove.

[0022] In one embodiment of the present invention, the turntable 3 has two different locking positions, corresponding to two different grooves where the positioning thimble abuts respectively; when the positioning thimble does not loc...

Abstract

The invention provides a positioning and locking device for a vibration simulation platform. The positioning and locking device comprises a rotatable turntable and at least one telescopic positioning ejector pin; at least two grooves are formed in the side face of the turntable, and the positioning ejector pin abuts against the grooves to lock the turntable. The fixed connection of a to-be-locked workpiece is not disassembled, and the direction of the to-be-locked workpiece is changed by rotating the turntable; a positioner is matched with the grooves for positioning, so that the positioning precision and the positioning operation speed are improved.

Description

technical field [0001] The invention relates to the field of positioning and locking, in particular to a positioning and locking device for a vibration simulation table. Background technique [0002] Mechanical vibration test is an effective means to detect the dynamic performance of mechanical equipment and test the dynamic stiffness of structures, and it is widely used in the design and inspection of aerospace structures. Dynamic tests generally include sinusoidal vibration tests, sweep frequency vibration tests and random vibration tests in the X, Y, and Z directions of the structure. During the vibration test in different directions, it is often necessary to turn over the electromagnetic driver in the shaking table equipment. The current method of flipping the electromagnetic driver is to remove the connecting bolts between the electromagnetic driver and the vibrating table after completing the test in one direction, change the excitation direction of the electromagneti...
