Description

Outer diameter measuring device for rotor coil of alternating current motor Technical Field The utility model relates to the technical field of alternating current motor test tools, in particular to an alternating current motor rotor coil outer diameter measuring device. Background After the rotor coil of the alternating current motor finishes winding, the maximum outer diameter of the rotor coil is required to be consistent with the designed outer diameter, if the maximum outer diameter of the coil exceeds the designed maximum outer diameter too much, the rotor coil can be contacted with the claw pole when the claw pole is assembled, so that the motor does not generate electricity, the motor can be directly burned when serious, at present, the maximum outer diameter of the rotor coil can only be roughly measured by a vernier caliper, the measuring position is the maximum outer diameter of the rotor coil, and the measuring mode has a great error to influence the quality of the motor. Disclosure of Invention In order to solve the problems, the utility model provides an outer diameter measuring device for a rotor coil of an alternating current motor. The technical scheme for solving the technical problems is as follows: An outer diameter measuring device of a rotor coil of an alternating current motor comprises a main bracket; Further, the method further comprises the following steps: the coil supporting component is connected with the main support; A measuring block, wherein one end of the measuring block is contacted with the circumferential surface of the measured coil; The auxiliary support is positioned above the coil supporting component, the auxiliary support is connected with the main support, the measuring block is movably matched with the auxiliary support, a first through hole is formed in the auxiliary support, and the other end of the measuring block is in clearance fit with the first through hole; the mounting plate is connected with the main support, a second through hole is formed in the mounting plate, and the first through hole is communicated with the second through hole; The numerical display comprises a display body and a measuring head, wherein the display body is arranged on the mounting plate, and the measuring head is inserted into the second through hole and matched with the axial end of the measuring block. Further, be equipped with first recess and second recess on the main support, be equipped with the screw hole in the first recess, coil support part and screw hole screw-thread fit, the auxiliary support is located the second recess.
