[0019] In some embodiments, the multi-functional testing device for motor products further includes a second retaining ring, which is fixed to the side of the shaft mounting end near the handle end, and the bearing is disposed between the first retaining ring and the second retaining ring.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0029] See attached figures. Figure 3 As shown, this utility model provides a multifunctional testing device for motor products, comprising:
[0030] A rotating component 1 extends along a first direction x. A measuring through hole 11 is provided along the length of the rotating component 1. The rotating component 1 inserts the rotating shaft of the motor product through the measuring through hole 11 for measurement, thereby determining whether the length of the rotating shaft of the motor product meets the standard. A reference object can be set in the measuring through hole 11 to help identify whether the length of the rotating shaft is qualified. For example, a scale can be set on the hole wall in the measuring through hole 11 to determine the length of the rotating shaft.
[0031] Positioning component 2, connected to the rotating component 1, includes a positioning ring 21 and a positioning pin 22. The positioning pin 22 extends along a first direction x and is fixed to the end of the positioning ring 21 away from the rotating component 1. The positioning component 2 detects whether the position of the positioning pin hole on the end cover of the motor product conforms to the standard by aligning the positioning pin 22 with the positioning pin hole on the end cover of the motor product. For example, when the shaft of the motor product is inserted into the measuring through hole 11, the positioning pin 22 can also align with the positioning pin hole, which serves as the basis for judgment.
[0032] The bearing 3 connects the rotating component 1 to the positioning component 2. By utilizing the cooperation between the bearing 3, the rotating component 1, and the positioning ring 21, the rotation of the motor product shaft can be checked to see if it can rotate and whether there is any jamming during rotation. For example, the rotating component 1 can be twisted to make it drive the shaft to rotate synchronously, thereby observing whether the working condition of the motor product shaft is qualified.
[0033] By integrating multiple testing functions—whether the shaft length of the motor product is qualified, whether the shaft rotation is qualified, and whether the position of the locating pin hole of the motor product's end cover is qualified—operators can perform multiple tests on the motor product simultaneously in one testing step. This greatly improves the efficiency of motor product testing and simplifies the equipment required for testing, thereby saving a significant amount of cost.

The limiting groove 12 is connected to the measuring through hole 11. The limiting groove 12 is used to detect whether the installation of the flat key of the motor product is qualified. When the rotating shaft is connected into the measuring through hole 11, the flat key will also be connected into the limiting groove 12 at the same time, thereby determining whether the installation of the flat key is qualified. At the same time, the limiting groove 12 and the flat key can drive the rotating shaft to rotate when the rotating component 1 rotates, thereby determining whether the rotating shaft is qualified.
[0035] In some embodiments, the positioning pin 22 includes a first positioning pin 22, a second positioning pin 22, a third positioning pin 22, and a fourth positioning pin 22. The first positioning pin 22, the second positioning pin 22, the third positioning pin 22, and the fourth positioning pin 22 are evenly arranged on the positioning ring 21. The four positioning pins 22 are used to detect the motor product, which further improves the detection accuracy.
[0036] In some embodiments, the end of the positioning ring 21 away from the rotating member 1 is provided with a mounting hole, and the positioning pin is fixed to the positioning ring 21 through the mounting hole. The mounting hole is used to install and fix the positioning pin 22.
[0037] In some embodiments, the rotating component 1 includes a shaft mounting end 13 and a handle end 14, the shaft mounting end 13 being connected to the handle end 14, the diameter of the shaft mounting end 13 being smaller than the diameter of the handle end 14, and the shaft mounting end 13 being used to mount the bearing 3, so that the rotating component 1 is mated with the bearing 3.
[0038] Continue to combine with the appendix Figure 1 and attached Figure 2 As shown, in some embodiments, the multifunctional testing device for motor products also includes a first retaining ring 4. The first retaining ring 4 is fixed to the side of the shaft mounting end 13 away from the handle end 14. The first retaining ring 4 is used to prevent the bearing 3 from falling off the rotating part 1. At the same time, by removing the first retaining ring 4, the bearing 3 can be separated from the positioning component 2, thereby facilitating the replacement of parts.
[0039] Continue to combine with the appendix Figure 2 As shown, in some embodiments, the multifunctional testing device for motor products further includes a second retaining ring 5. The second retaining ring 5 is fixed to the side of the shaft mounting end 13 near the handle end 14. The bearing 3 is disposed between the first retaining ring 4 and the second retaining ring 5. The second retaining ring 5 is used to restrict the bearing 3 and prevent the shaft wheel from shifting position during operation, thereby ensuring the accuracy of the test results.
[0040] Continue to combine with the appendix Figure 3As shown, in some embodiments, the shaft mounting end 13 is provided with a snap-fit groove 131 along its circumferential direction y on the side away from the handle end 14, and the first retaining ring 4 is disposed in the snap-fit groove 131. The snap-fit groove 131 is used to load the first retaining ring 4, further improving the stability of the multi-functional testing device for motor products.
