本文介绍一种B-42型便携式振动仪,用于处理大型铸件和焊接结构件,其目的是减少工件内的残余应力(取代热处理),该振动仪可与各种振动装置配合使用。振动仪的王作原理是以调整其偏心块为前提,以激发调整机械振动为基础来进行各种共振频率下的激发振动。其结构是以共振临界状态下,即使振动力达到50kN。振动仪仍可正常工作来考虑的。在焊接机体1上装有一空心轴4,空心轴两端装有310型轴承(如图),用锁紧螺钉将两侧偏心块2、3
This article describes a B-42 Portable Vibrometer designed to handle large castings and welded structures with the goal of reducing residual stresses in the workpieces (replacing heat treatment) that can be used with a variety of vibrating devices. Vibrometer Wang Zuo principle is to adjust its eccentric block as a prerequisite to stimulate the adjustment of mechanical vibration based on a variety of resonant frequency excitation vibration. The structure is based on the critical state of resonance, even if the vibration force reaches 50kN. Vibrometer can still work to consider. In the welding body 1 is equipped with a hollow shaft 4, hollow shaft equipped with 310 type bearings at both ends (shown), with locking screws on both sides of the eccentric blocks 2,3
