However, in the prior art, the detection of the outer diameter of the rotor is mostly performed manually. The inspector holds a micrometer with high precision, clamps the rotor in the bayonet of the micrometer, and reads it manually. The unqualified rotors are rejected, and the qualified rotors enter In the next process, the measurement of the micrometer is actually that the micrometer screw on the micrometer bears against the outer cylindrical surface of the rotor, and then reads. The detection method in the prior art will have artificial detection errors, and the rotor is stuck in the bayonet of the micrometer. Each time is measured according to the tangential line of the rotor, and the measurement accuracy cannot be guaranteed, which will affect the quality of the motor, and the detection method in the prior art is inefficient

[0021] Example: see Figures 1 to 3 As shown, a detection device for the outer diameter of a rotor includes a "匚"-shaped fixed bracket 1, and the upper and lower ends of the fixed bracket 1 are respectively provided with relative measuring seats 2. The measuring seat 2 includes a bottom plate 21, and , The rear two sides are respectively fixed with pillars 22, and the pillars 22 are fixed with arc-shaped support plates 23, and the two ends of the support plates 23 are hinged with positioning rollers 25 through the hinge shaft 24, and the middle part of the support plate 23 is plugged and fixed with guide rods 28. A T-shaped test piece 27 is inserted between the positioning rollers 25. A vertical guide groove 271 is formed on the test piece 27. The guide rod 28 is inserted into the guide groove 271 of the test piece 27. The test pieces 27 are distributed in the In the middle part of the guide rod 28, a vertical column 28 is fixed on the support plate 23 on both sides of the tes...

A rotor external diameter detection device disclosed by the present invention comprises a [-shaped fixing support, opposite measuring bases are arranged at the upper and lower ends of the fixing support respectively, and the measuring base at the lower side of the fixing support is fixed on the fixing support, and a plurality of guide columns are fixed on a bottom plate of the measuring based at the upper side of the fixing support and are plugged in the fixing support. A cylinder is fixed on the upper end face of the fixing support, and a piston rod of the cylinder penetrates the fixing support to be fixed on the bottom plate of the measuring base at the upper end of the fixing support. According to the present invention, an electromechanical device is used to substitute for the manual artificial detection of the external diameter of a rotor, thereby not only being convenient to detect the rotor, improving the detection efficiency, but also positioning the rotor effectively, and detecting the external diameter accurately.
Description
[0001] Technical field: [0002] The invention relates to the technical field of motor assembly equipment, and more specifically relates to a detection device for the outer diameter of a rotor. [0003] Background technique: [0004] At present, the stator and rotor are the important components of the motor. The best matching clearance between the rotor and the stator is calculated by the designer, and the stator and rotor are produced according to the designed clearance during production. To achieve the clearance between the stator and the rotor designed by the designer, the size of the rotor and the stator must be guaranteed It meets the design requirements, but in actual production applications, when the stator and rotor are assembled, sophisticated testing equipment must be required to measure the dimensions of the two. However, in the prior art, the detection of the outer diameter of the rotor is mostly performed manually. The inspector holds a micrometer with high precis...
