目前我国已在服役和即将服役的PL型导弹光学非触发引信舱(简称引信舱)与发动机舱是由螺纹连接在一起的。根据地面维护要求,对接引信舱时所用的对接工具不允许碰擦引信舱表面的四个透明窗口玻璃,而且拧紧后还要检查拧松力矩不得小于某个给定的力矩值。由于有这些要求,在导弹总装时,希望有一种使用起来得心应手的方便工具。 At present, China has been in service and is about to service the PL missile optical non-triggering fuse (referred to as the fuse box) and the engine compartment is connected by a screw thread. According to the ground maintenance requirements, the docking tools used in the docking fuselage should not touch the four transparent windows on the surface of the fuse box, and the tightening torque must not be less than a given moment after tightening. Owing to these requirements, it is hoped that there will be a handy and convenient tool to use when assembling the missile.
