Centrifugal machine table board fixing for acceleration test

Abstract

The invention belongs to the technical field of centrifugal machines, and particularly relates to a centrifugal machine table board fixing for an acceleration test. The table board comprises a rack protection board, a centrifugal machine support, a work cavity protection board, a work rotating disc, a cover plate and a processor; the centrifugal machine support comprises a supporting table, the processor is provided with a processing chip and a buzzer, a storage box is arranged on one side of the processor, the storage box is provided with a positioning pin, the cover plate is provided with asquare key block, a first detection switch is arranged on the inner wall of the work cavity protection board, four through holes are evenly distributed in the work rotating disc, a plug pin through hole is formed in the supporting table, and four second proximity switch supports are fixedly connected to the lower surface of the supporting table, and are connected with a second proximity switch, athird proximity switch, a fourth proximity switch and a fifth proximity switch. The work table board can be fixed, the detection function is achieved, a worker is prevented from starting a centrifugalmachine under the fixed state of the work table board and causes fixed device damage, and use is safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of centrifuges, and in particular relates to a centrifuge table top fixing device for acceleration tests. Background technique [0002] Because different test equipment produces acceleration loads in different ways, when selecting acceleration test equipment, it is necessary to carefully analyze the function and characteristics of the test piece. There are two types of commonly used equipment: centrifuges and rocket skids with slide rails. The centrifuge generates an acceleration load by rotating around a fixed axis, so the direction of acceleration always points radially to the center of rotation of the centrifuge, and the direction of the load generated by the acceleration is always radially outward from the center of rotation. When the specimen is directly installed on the experimental arm of the centrifuge, the specimen is subjected to two kinds of motions of rotation and translation at the same time. ...

AI Technical Summary

Problems solved by technology

In the existing centrifuges used for acceleration tests, because the rotation of the worktable is not fixed, it is often difficult to adjust the test piece to a suitable position and clamp and fix it when installing the test piece, resulting in time-consuming and laborious installation of the test piece. The device has no detection function, and the user does not know whether the worktable is released from the fixed state, so the centrifuge is often started when the worktable is fixed, resulting in damage to the device
