The utility model relates to a robot of crawling based on guide leads for in placing the clearance between stator core and rotor core, in order to span in the stator coil groove or on changeing the subcoil groove. Should crawl the robot includes firstly, the unilateral mechanism of second, both ends are respectively with first, the coupling mechanism that the unilateral mechanism of second connects, and guiding mechanism, it is first, the unilateral mechanism of second can adsorb on the iron core, and can move on the iron core, guiding mechanism is first including locating, barrel on unilateral mechanism of second or the coupling mechanism and be used for wearing to locate the guide on stator core or the rotor core, the both ends of guide are used for fixing the axial both ends at the ironcore, with the guide barrel, it is first, unilateral mechanism of second and the removal of coupling mechanism on the axial direction of iron core. Adopt the aforesaid to creep the robot and examineand repair and test with the rotor subassembly stator module, can labour saving and time saving, in addition can be so that creep the robot and move the route and roughly be straight path through setting up guiding mechanism.
