the first step is as follows: installation of the guide plate and the driving disc: inserting the shaft sleeve into the mounting hole of the guide plate until the guide plate is abutted against the convex ring, and rotatably matching the driving disc with the convex ring through the rotating groove;
the second step is that: and (3) mounting a test needle seat: the guide sleeve is in rotating fit with the rotating groove of the shaft sleeve, the detection end of the test needle rod on the test needle seat faces the guide sleeve, meanwhile, the test end of the test needle rod is inserted into the through hole of the guide sleeve, then, a stress column on the test needle seat penetrates through the linear sliding groove and then is inserted into the arc-shaped groove, the linear sliding block is in sliding fit with the guide groove, the test needle rod on the test needle seat is inserted into the through hole by adjusting the axial position of the guide plate and rotating a proper angle, and then the convex ring is detachably connected with the guide plate through a connecting piece;
in a second step, the mounting of the needle bar is tested: arranging a check ring on the outer peripheral surface of the test needle rod, inserting a spring into the outer periphery of the test needle rod, connecting one end of the spring with the end surface of the check ring, which is far away from the test end of the test needle rod, inserting the test needle cylinder from the end, which is far away from the test end, of the test needle rod, abutting the check ring against the inner peripheral surface of the test needle cylinder, which is close to the test end of the test needle rod, abutting one end of the spring, which is far away from the check ring, against an abutting ring in the test needle cylinder, penetrating a rubber insulating sheet at one end, which is far away from the test end, of the test needle rod, through the test needle cylinder, inserting the part, which is located between the test needle cylinder and the rubber insulating sheet, into a push needle chute, so that the test needle cylinder is located in an;
the third step: installing a limiting ring plate: moving the limit ring plate to one side of the guide plate far away from the driving disc, wherein a channel of the limit ring plate is opposite to the mounting hole of the guide plate, and then detachably mounting limit columns between the limit ring plate and the guide plate through a connecting piece, wherein the limit columns are distributed along the edge of the limit ring plate, so that a space for the test needle seat to move is formed between the limit ring plate and the guide plate;
the fourth step: installing a ring baffle: the baffle ring plate penetrates through the shaft sleeve and then abuts against the driving disc, meanwhile, an arc-shaped groove on the driving disc is covered, and the baffle ring plate is detachably connected with the driving disc through a connecting piece;
the fifth step: and (3) mounting and testing: the driving module is started to drive the driving part to work so as to drive the driving disc to rotate around the shaft sleeve, the stress column drives the linear sliding block to relatively slide on the guide groove under the arc guiding action of the arc-shaped groove, whether the linear sliding block is in a clamping state or not in the sliding process is judged, and if yes, the first step is returned; if not, the installation is finished.
10. Use of a modular armature measuring jig according to any of claims 1 to 8 characterised by the steps of:
the method comprises the following steps: inserting an armature rotor into the guide sleeve, wherein each commutator segment of the armature rotor corresponds to the through hole on the guide sleeve;
step two: a lead wire connected with a lead terminal on the test needle sequentially passes through the first threading groove and the second threading groove and then is connected with the armature rotor measuring system;
step three: and starting the driving module, driving the driving disc to rotate by using the driving part, driving the linear sliding block to relatively slide on the guide groove under the arc guiding action of the arc groove by using the stress column, and simultaneously driving the test needle on the test needle seat to contact with the commutator segments on the armature rotor after penetrating through the through hole, thereby forming an effective loop of integral detection and observing and acquiring a measurement result through the armature rotor measurement system.
