Embodiment Construction

[0012] like figure 1 Shown is the sudden stop mechanism of the present invention, i.e. the basic form of the present invention, consisting of a support 1, a guide shaft 2, an inertia ring 3, a bearing 4, a cylindrical spring 5, a yoke 6, and a retaining pin 7. The bracket 1 equipped with the armature is fixed on the base of the sudden stop platform, the guide shaft 2 is installed on the bracket 1, the inertia ring 3 is installed on the outside of the yoke 6, the yoke 6 is installed on the guide shaft 2 through the bearing 4, and the bracket 1 Both the armature and the yoke 6 have grooves for installing the cylindrical spring 5, and the cylindrical spring 5 keeps the yoke 6 at a certain distance from the armature on the bracket 1 in a free state, that is, the inertia ring 3 keeps a certain distance from the bracket 1 , the stop pin 7 is installed on the inertia ring 3. When the sudden stop platform needs to stop suddenly, the yoke iron 6 is energized while the sudden stop platf...

Abstract

The invention provides a hang-up mechanism for a hang-up table, which comprises a bracket, a guiding axis, an inertia ring, a bearing, a cylindrical spring, a yoke iron and a stop pin. When the yoke iron is electrified, under the effect of electromagnetic attraction, the inertia ring is attracted with the bracket along the guiding axis; the stop pin on the inertia ring moves along the inertia ring onto a motion trail of a revolving stop block on the hang-up table; the stop pin collides with the stop block; the inertia ring rotates; according to the law of conservation of kinetic energy, energy of the revolving motion of the hang-up table is transferred to the inertia ring; and the revolving axis of the hang-up table is hung up. In the invention, because the inertia ring is adopted and a spring strip is installed on the stop pin of the inertia ring, when the stop block collides with the stop pin, the kinetic energy of the revolving axis of the hang-up table is transferred so that the energy of the revolving motion of the hang-up table is transferred to the inertia ring. The hang-up mechanism greatly improves the hang-up dynamic indicators, and has the advantages of low adjacent amplitude ratio, short damped oscillation cycle, low power consumption and convenient processing and installation.

Description

technical field [0001] The invention relates to a sudden stop mechanism, in particular to a sudden stop mechanism for a sudden stop platform, which can be used as a sudden stop mechanism for rotating parts in testing equipment. Background technique [0002] The sudden stop table is a single-axis rate turntable with sudden stop function. It is mainly used for instrument performance testing. During the test, the rotary shaft of the sudden stop table works at a speed state, and then the sudden stop table is operated to make the rotary shaft stop instantly to detect the measured The performance parameters of the instrument at the moment when the speed motion suddenly stops. The sudden stop of the rotary axis of the sudden stop platform is called "sudden stop". The higher the dynamic index of the sudden stop, the better the real performance of the instrument under test can be detected. The dynamic sudden stop index of the sudden stop station includes the adjacent amplitude ratio ...
