DESCRIPTION ANTI-SHIFT SHAFT EXTENSION LENGTH DETECTION DEVICE Technical Field of the Invention
The present invention relates to an anti-shift shaft extension length detection device.
Background of the Invention A core is fixed on a rotor shaft, an end ring is fixed on an end face of the core, and the distance from the end of the rotor shaft to the end face of the core is the shaft extension length. After a rotor is well assembled, the detection of the shaft extension length is required. A too large or small shaft extension length may influence the service performance of the motor, increase the noise during the operation of the motor, and even cause damage to the bearing or core to reduce the service life of the motor.
Summary of the Invention
An objective of the present invention is to provide a shaft extension length detection device which can be used for shaft extension length detection.
The present invention employs the following technical solutions. An anti-shift shaft extension length detection device is provided, including a soleplate; a fixed member and a meter-type universal length measurement tool are provided on the soleplate, and the meter-type universal length measurement tool is located on a front side of the first fixed member; a shaft extension positioning member is fixed on the first fixed member, the shaft extension positioning member consisting of a positioning member body and a positioning member bulge located on a rear side of the positioning member body; a positioning groove is formed in the shaft extension positioning member, the positioning groove running through the positioning member body and the 1 2017100871 26 Jun2017 positioning member bulge from front to back; a rear end of the positioning member bulge is located on a rear side of the first fixed member; and an evading space for evading an end ring of a rotor is formed between a lower edge of the rear end of the positioning member bulge and an upper end face of the soleplate; the radial section of the positioning groove at the positioning member body is circular. This arrangement is used to position the rotor shaft and prevent the end of the rotor shaft from shifting upward so as to ensure the detection precision.
Preferably, the radial section of the positioning member bulge along an axis of the positioning groove is arc-shaped, and an opening of the arc faces upward. This arrangement is convenient for the detection personnel to detect the shaft extension of the rotor shaft. The shaft extension of the rotor shaft can be detected just by two actions: putting the rotor shaft down and pushing the rotor shaft.
The shaft extension length detection device of the present invention can be used for shaft extension length detection; and the detection is convenient and the detection precision is high.

The positioning member bulge 6 consists of a first positioning member bulge segment 61 and a second positioning member bulge segment 62; and the thickness of the first positioning member bulge segment 61 is greater than that of the second positioning member bulge segment 62, and the thickness of the second positioning member bulge segment 62 is less than the distance between the rotor shaft 12 and an inner wall of the end ring 11.
As shown in Fig. 1, Fig. 2 and Fig. 3, a fitting groove 21 is formed in the first fixed member 2, the fitting groove 21 running through the first fixed member 2 from front to back and also running through the first fixed member 2 upward; a lower edge of the positioning member body 5 is located on a lower side of a lower edge of the positioning member bulge 6 so that the positioning member body 5 and the positioning member bulge 6 form a stepped structure; the first positioning member bulge segment 61 is fitted within the fitting groove 3 2017100871 26 Jun2017 21; a rear end face of the positioning member body 5 comes into contact with a front end face of the first fixed member 2, and the thickness of the first fixed member 2 from the front end face to the rear end face is less than the axial length of the positioning member bulge 6.
Wherein, an outer edge of the positioning member bulge 6 and the fitting groove 21 are the same in shape, both being arc-shaped. The radial section of the positioning groove at the positioning member body 5 is circular. The radial section of the positioning member bulge 6 along an axis of the positioning groove 41 is arc-shaped, and an opening of the arc faces upward.
