Description
Technical field
The present invention relates to a kind of centrifuge coupon level commutation locking device, particularly relate to a kind of centrifuge coupon level commutation locking device that can change coupon level angle simply, rapidly.
Background technology
Routine test centrifuge and precision centrifuge are the large important compositions of two in centrifuge.The hypergravity that routine test centrifuge is mainly used in components and parts detects, and this detection needs higher acceleration precision usually, and is all large batch of, has high requirements to the operability of centrifuge and ease for use.Precision centrifuge then for the calibration of inertial navigation and inertial guidance linear accelerometer, defines the accuracy requirement of each grade precision centrifuge for linear accelerometer setting angle in " the precision centrifuge calibrating standard of linear accelerometer ".
Be arranged on centrifuge by fixture by components and parts or accelerometer in process of the test, the acceleration being rotated the centrifugal force generation brought by centrifuge realizes the hypergravity detection of components and parts or the calibration of linear accelerometer.Modern components and parts detect or accelerometer calibration usually needs to be commutated, to realize detection or the calibration of 90 °, 180 °, 270 °.
The coupon level commutation locking device be applied on ground installation is more ripe, but the level commutation locking device being used centrifuge test specimen rarely has bibliographical information.And due to the special after the match stress of centrifuge, the such device on ground installation can not be indiscriminately imitated on centrifuge.
At present, in process of the test, be usually equipped with testing stand, piece fixture is connected on testing stand by the mode be spirally connected, and when needs commutate, then fixture and test specimen together must be pulled down, again be screwed onto again on testing stand after commutation, the level commutation of test specimen could be realized.Owing to operating steps such as all will carrying out screw disassembling, fixture commutates, screw is reinstalled at every turn, greatly reduce detection or calibration efficiency, as large batch of components and parts detection or linear acceleration meter calibrating need be carried out, then need repeatedly to install and remove fixture, waste the plenty of time, meanwhile, the accuracy requirement of the test specimen setting angle of precision centrifuge is also met.
Summary of the invention
Object of the present invention is just to provide a kind of centrifuge coupon level commutation locking device that can change coupon level angle simply, rapidly to solve the problem.
The present invention is achieved through the following technical solutions above-mentioned purpose:
