摘　　要：给出了激光校正的原理和激光测量方法,并用于某型号继电器,具体测试了其簧片气隙的大小和分布情况。利用继电器金属簧片进行了大量的激光校正测试试验,测试结果表明:激光照射后,簧片得到的校正量h与激光测量点到激光校正点的间距x2成正比例线性关系,可用h=kx2近似表示;而激光功率P和照射时间t与簧片获得的校正量h之间则大致成抛物线关系,起始时功率越大,时间越长,校正量越大,但过了拐点之后情况则相反。测试结果同时表明:在性能指标范围内,激光校正并不会影响继电器簧片的机械寿命。分析和计算证明,选择合适的激光功率P与时间参数t,利用激光对该继电器的簧片气隙进行校正是可行的;结合气隙大小的测试数据分析可知,生产线上绝大多数继电器的簧片气隙调整只需通过静簧片的激光校正就能得以实现,与手工校正相比具有较高的校正效率。The principle of laser-adjusting and the method of laser-measuring were described and applied to adjust the gaps of one model relay. A plenty of tests and measurements for adjusting relay＇s springs by laser beam were finished. After data analyzed, several results were summarized and shown as follows： the laser-adjusting quantum h is in linear direct proportion to the distance x2 between measuring point and adjusting point, and the formula can be expressed by h=kx2. The laser power P and the irradiation time t are approximate parabola relation curves to adjusting quantum h. The stronger the power P and the longer the irradiation time t, the bigger the quantum h at the rise phase, But when it is over the inflexion, the results are opposite. The experimental results also show that there is no negative influence of laser-adjusting on the relay＇s mechanical life. It is feasible for adjusting the relay＇s gap by laser beam when the laser power P and the time t set equal each other. With combining the test data of the relay＇s gap, it is known that the gap of the most relays on the assembly line can be adjusted correctly after adjusting the settled spring only, which will be more efficiency in comparon of laser-adjusting with manual-adjusting.
