激光反馈自动校正装置,是用圆光栅和激光干涉仪组成丝杠磨床传动链误差测量系统,把临床测量机床的动态误差信号,反馈到由步进电机等组成的校正执行机构,对机床误差进行“随时”的自动校正,在丝杠加工过程中,使机床误差逼近于“零”,以达到控制磨削高精度丝杠的目的.激光是六十年代出现的新技术,激光干涉原理正在计量领域里应用,如光电光波比长仪、激光丝杠检查仪等.但激光应用在机加工恒温车间里和直接应用在精密机床上,还要解决许多难题,如激光波长小数有理化问题、振动问题、温度、气压修正问题、激光防护及可靠工作问题等.就机床来说,过去往往用制造“母机”的方法,如涡轮母机.丝杠母机等,来提高零件加工精度,但这种主要靠机械的手段.来提高精度的方法.已本文介绍了观察激光引爆猛炸药爆轰成长过程的实验方法和用太安(PETN)作为第一装药的实验结果.测试装置的设计原则是:(1)利于观察激光引爆和爆轰成长,这就要求激光易于照射装药,装置的密封性好:(2)能较直观地观察爆轰成长过程,这就要求装置透光性好,装配方便.测试装置的玻璃盖片的作用是当激光照射装药表面时,阻止炸药的溅射,从而防止炸药飞散造成的冷却,保持了炸药初始反应的温度和
Automatic laser feedback correction device is composed of a circular grating and laser interferometer screw grinder drive chain error measurement system, the clinical measurement of the dynamic error signal machine tool, fed back by the stepper motor and other components of the correction of the implementing agencies, the machine error “Automatic” at any time, in the lead screw machining process, the machine error is close to “zero”, in order to achieve the purpose of controlling the grinding of high precision screw.Laser is a new technology appeared in sixties, laser interferometry principle is being measured Applications in the field, such as optical and optical wavelength ratio meter, laser lead screw tester, etc. However, laser applications in the machining and thermostatic workshop directly on the precision machine tools, but also solve many problems, such as laser wavelength decimal physical problems, vibration Problems with temperature, pressure correction, laser protection and reliable work issues, etc. In the past, the machine tools used to make “main machine” methods such as turbomachinery and screwdriver to improve the machining accuracy of parts. However, By mechanical means to improve the accuracy of this article has been introduced to observe the detonation of laser detonation explosives detonation growth of the experimental method and the use of PET (PETN) The first experimental results of the design of the test device design principles are: (1) conducive to observe the laser detonation and detonation growth, which requires the laser easy to irradiate the charge, the device has good sealing: (2) can be more intuitive observation Detonation growth process, which requires a good light transmission device, easy assembly.The cover glass test device is the role of the laser radiation when the surface coating, to prevent the sputtering of explosives, thereby preventing the dispersion caused by the cooling of explosives, to maintain Explosive initial reaction temperature and
