In order to solve the problem, the utility model provides a when having reduced slot angular surveying error among the electric motor rotor, the novel motor core that has promoted detection efficiency detects frock.

In order to reach above-mentioned purpose, the utility model discloses a novel motor core detects frock, including examining a base and detecting the axostylus axostyle, examine a base center detachable and be equipped with the round pin axle of examining a base surface of perpendicular to, examine a base top and be provided with along the axostylus axostyle mounting bracket of horizontal direction, the rotatable cartridge of first locating hole is sold epaxial through the axle lever mounting bracket one end, and the detection axostylus axostyle passes through the second locating hole cartridge at the other end of axostylus axostyle mounting bracket, detects and is provided with two at least position complex locating pins one on the other between axostylus axostyle and the round pin axle, two locating pins set up respectively on axostylus axostyle mounting bracket and examine a base, and examine a base outer edge be provided with and detect axostylus axostyle complex angle detection scale. The effect that sets up like this lies in passing the fluting at motor core middle part through examining the round pin axle that a base center set up, fix a position motor core's mounted position, prevent that motor core position from taking place the skew in the testing process, influence measuring precision, and through two locating pins in axostylus axostyle mounting bracket and the detection axostylus axostyle, both ends about the same rotor chute of motor core are installed to the counterpoint respectively, simultaneously according to installing the reading of the detection axostylus axostyle directive angle detection scale at axostylus axostyle mounting bracket end, thereby directly reacing the angle of rotor chute in the motor core, compare in conventional detection mode, its detection efficiency has been promoted greatly. On the other hand, through the different motor core hole of detachable round pin axle adaptation, simultaneously rotatable axostylus axostyle mounting bracket also can adapt the rotor chute of different angles as required to make this equipment have good commonality, can the various size of motor core detection processes of adaptation.

The further scheme is that the head of the positioning pin is arranged in a circular truncated cone shape. The positioning pin head that the effect that sets up lies in adopting the round platform form to set up like this has better card and establishes the transition effect, reaches the purpose of rotor chute mounted position in the quick location motor core, has good auto-lock nature simultaneously, can make things convenient for motor core's installation and dismantlement.

According to a further scheme, the diameter of the detection shaft lever is smaller than or equal to that of the second positioning hole, a positioning through hole communicated with the second positioning hole is formed in one end, far away from the pin shaft, of the detection shaft lever, the detection shaft lever is fixedly arranged in the second positioning hole through a butting part penetrating through the positioning through hole, and the detection shaft lever is perpendicular to a plane where the shaft lever mounting frame is located. The effect that sets up like this lies in will detecting axostylus axostyle fixed mounting in the second locating hole through the position portion that supports, prevents to detect that the axostylus axostyle is not hard up in the second locating hole and drops, and the while is through the axostylus axostyle mounting bracket that mutually perpendicular set up and the mounted position that detects the axostylus axostyle further fixes a position motor core.

In a further scheme, a positioning pointer extending towards the angle detection scale is arranged at the lower part of the detection shaft rod. The effect that sets up like this lies in through the angle reading in the angle detection scale that sets up on the location pointer counterpoint that detects the axostylus axostyle afterbody to reduce the measuring error of chute contained angle.

The utility model discloses a novel motor core detects frock, the round pin axle that sets up through examining a base center passes the fluting at motor core middle part, location motor core's mounted position prevents that the skew from taking place at the motor core position in the testing process, influence measuring precision, set up two locating pins in axostylus axostyle mounting bracket and detection axostylus axostyle one by one again, both ends about the same rotor chute of motor core are installed to counterpointing respectively, the reading of the directional angle detection scale of location pointer through observing the detection axostylus axostyle lower part at last, reach the angle of rotor chute among the motor core.

To sum up, the utility model has the advantages of can have reduced the requirement to the measurement personnel when having promoted the big batch that detects of detection rate, corresponding inspection method is mastered more easily, has reduced rotor chute angle measurement error.
