Abstract
The utility model relates to a device for detecting the natural frequency of a beam. The device comprises a vibration exciter, a base, a slide way, a fixing bolt, a clamping fixture, a bolt, a clamping plate and an upright column, wherein the slide way is arranged on the base; the vibration exciter is fixed on the clamping fixture and mounted in the slide way through the fixing bolt; the upright column is fixed at one end of the base; and the clamping plate is mounted on the upright column through the bolt and can clamp a cantilever beam. The product has a simple structure, is convenient to use, operate and mount, saves time and labor, improves the detection precision, and guarantees the accuracy of vibration shape analysis; and the relative positions between the vibration exciter and the cantilever beam have no need to be aligned one by one during detection.
Description
Technical field: the utility model relates to a kind of beam natural frequency pick-up unit.
Background technology: at present, existing semi-girder frequency detecting device, vibrator and semi-girder do not have special-purpose stationary fixture, need be during detection by the relative position between part centering vibrator and the semi-girder, not only trouble is time-consuming, and influence accuracy of detection, make the conformal analysis that shakes error occur.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, a kind of beam natural frequency pick-up unit is provided, it has mainly solved existing semi-girder frequency detecting device, vibrator and semi-girder do not have special-purpose stationary fixture, need be during detection by the relative position between part centering vibrator and the semi-girder, trouble not only, and influence problem such as accuracy of detection.The purpose of this utility model is achieved in that beam natural frequency pick-up unit is made of: vibrator, base, slideway, set bolt, anchor clamps, bolt, clamping plate, column.Base is provided with slideway, and vibrator is fixed on the anchor clamps, and is installed in the slideway by set bolt, but its move left and right, column is fixed on an end of base, and clamping plate are contained on the column by bolt.This product structure is simple, uses operation easy for installation, need not during detection by the relative position between part centering vibrator and the semi-girder, and is time saving and energy saving, improved accuracy of detection, the accuracy of the conformal analysis that guaranteed to shake.
