Description

Technical Field

[0001] The utility model relates to the technical field of motor detection, in particular to a motor detection tool. Background Art

[0002] Missile-mounted motors are motors used in missile-mounted systems to provide power, adjust the position of mechanical components, or perform other specific functions. They have a wide range of applications in the defense and military sectors. For example, in guidance systems, missile-mounted motors can control the missile's attitude and trajectory, enabling precise strikes on targets. In torpedoes, missile-mounted motors can be used in steering systems to control the deflection angle of the rudders, achieving torpedo heading control. In drones, missile-mounted motors can control the aircraft's pitch and yaw angles for attitude adjustment. This makes missile-mounted motors an indispensable part of the defense and military sectors.

[0003] The importance of missile-mounted motors makes their quality inspection after production particularly important, and the speed detection in the quality inspection is also the most important, because whether the speed meets the standard determines whether the missile-mounted motor can be used normally. Existing missile-mounted motor detection generally directly connects the speed sensor at the drive end for detection, but some missile-mounted motor structures, such as the attached Figure 3 As shown, its drive shaft is set inside, and the drive gear 101 is fixed on the internal drive shaft and the gear 101 is exposed outside. When in use, it is only used by meshing the gear 101 with the gear in the missile-borne system. It is difficult to directly connect the speed sensor at the drive gear 101 for quality inspection of this missile-borne motor, so it is difficult to achieve detection through traditional methods.
