[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] In view of the lack of a monitoring device for the axial position of the pulley during the assembly process of the automotive generator in the relevant technology, the existing height gauge and universal tool microscope are used for measurement, which has the problems of low accuracy and long measurement time, thus affecting the production progress.

[0034] First, as Figure 1 As shown, the present application provides a multi-hanging ear generator inspection fixture, which includes: a base 1 and a measuring ruler 4; wherein,

[0035] The base 1 has at least two positioning pins 2 at both ends, and the positioning pins 2 are used to be inserted into the ear holes of the generator and to be positioned and matched with the ear holes. A measuring ruler 4 is arranged at one end in the middle of the base 1, and the measuring ruler 4 is used to align with the measuring dimension groove in the pulley groove of the generator.

[0036] It is worth noting that the present application sets up a base with a measuring ruler in the middle and positioning pins at both ends, uses the positioning pins to position the ear holes, and then judges whether the motor size is qualified based on the alignment position of the measuring ruler and the motor pulley groove.

[0037] Furthermore, if Figure 2 As shown, a driving rod 5 is provided in the middle of the base 1, and the driving rod 5 is axially parallel to the two locating pins 2. Optionally, the driving rod 5 and the locating pins 2 are respectively arranged on two symmetrical sides of the base 1, and the driving rod 5 and the locating pins 2 are respectively extended in opposite directions.

[0038] It is understandable that the driving rod 5 is used for the operator to move by hand. When in use, the operator can adjust the position and posture of the positioning pin 2 to align with the hanging ear hole of the motor through the driving rod 5, and then apply a thrust to the driving rod 5 to make the positioning pin 2 extend into the hanging ear hole of the motor, and perform positioning matching.

[0039] In some preferred embodiments, the measuring ruler 4 comprises: a mounting base 41 and a ruler body 42; wherein,

[0040] A mounting base 41 is mounted in the middle of the base 1 ; a ruler body 42 is connected to the mounting base 41 , and the length direction of the ruler body 42 is parallel to the axes of the two positioning pins 2 .

[0041] It is understandable that if Figure 2 As shown, the end of the ruler body 42 is configured as a pointed alignment end, so that the operator can read the alignment position of the ruler body 42 accurately.

[0042] In the first specific embodiment provided in the present application, in order to improve the adaptability of the multi-hanging-ear generator inspection fixture, the mounting base 41 is detachably connected to the base 1 .

[0043] It is worth noting that there are many types of generators, and the standard size of the distance between the pulley teeth and the motor hanging ear hole is also different. In order to adapt to different generators, a variety of ruler bodies 42 can be set, and by replacing different ruler bodies 42 and connecting them to the mounting base 41, the inspection fixture for different motors can be quickly switched.

[0044] In the second specific embodiment provided by the present application, the measuring ruler 4 includes: a position adjustment portion and a ruler body 42

[0045] A position adjustment part is installed on the base 1, and the movable end of the position adjustment part can perform telescopic movement to get closer to or away from the base 1; a ruler body 42 is connected to the movable end of the position adjustment part, and the ruler body 42 can move with the movable end of the position adjustment part.

[0046] It is worth noting that in order to improve work efficiency, timely and rapid adjustments can be made when facing different generators, and subsequent size judgment processes can be performed. The operator can adjust the height of the position adjustment part through the position adjustment part to adapt to different generators and align it with the pulley groove of the generator.

[0047] In combination with the above second specific embodiment, in some specific implementations, the position adjustment unit includes:

[0048] A sleeve is erected on the mounting base 41; a movable rod has one end movably inserted into the sleeve and the other end extending out of the sleeve and connected to the ruler body 42. The movable rod can be telescopically moved along the sleeve to drive the ruler body 42 to approach or move away from the mounting base 41.

[0049] Furthermore, a locking piece is detachably provided on the sleeve, and the locking piece is used to pass through the sleeve and lock the movable rod.

[0050] It is worth noting that the movable rod is provided to drive the ruler body 42 to move and adjust to meet the motor size standard. After the ruler body 42 reaches the preset position by moving the movable rod, the movable rod is locked by a locking member so that the ruler body 42 maintains the position unchanged during use.

[0051] In some other preferred embodiments of the present application, in order to improve the versatility of the inspection tool, the two positioning pins 2 can be moved toward or toward each other along the base 1. Specifically, a slide rail is provided on the base 1, and the slide rail is slidably connected to the two positioning pins 2.

[0052] In a second aspect, the present application provides a generator detection method using the above-mentioned multi-hanging ear generator detection fixture, which comprises:

[0053] Step S1, move the base 1 until the two positioning pins 2 on the base 1 are respectively inserted into the two hanging ear holes of the generator and are positioned and matched with the hanging ear holes.

[0054] Step S2, adjusting the posture of the base 1 so that the measuring ruler 4 is aligned with the pulley groove of the generator.

[0055] Step S3, reading and judging whether the size of the generator is qualified according to the alignment position between the measuring ruler 4 and the measuring size groove of the pulley groove.

[0056] It is worth noting that before testing, the standard position slot layer area of ​​the measuring size slot needs to be determined according to the preset size. When observing the alignment area of ​​the measuring ruler 4, if the measuring ruler 4 is aligned with the standard position slot layer area of ​​the pulley groove, the generator size is judged to be qualified. If the measuring ruler 4 is aligned with the non-standard position slot layer area of ​​the pulley groove, the generator size is judged to be unqualified.

[0057] In summary, the present application sets up a base with a measuring ruler in the middle and positioning pins at both ends, uses the positioning pins to position the ear holes, and then determines whether the motor size is qualified based on the alignment position of the measuring ruler and the motor pulley groove.
