The shaft section detection tool is convenient to use and has high detection precision.
[0031] Continuing to refer to Figure 2 Optionally, the detection piece 1 comprises a detection piece body 11 and a plurality of abutting rods 12, and the detection piece body 11 has a slot 110.
[0032] The plurality of abutting rods 12 are arranged in parallel with each other, one end of each abutting rod 12 is connected with the detection piece body 11, and the other end forms the detection plane 100, the abutting space 120 is defined between the plurality of abutting rods 12, the abutting space 120 is in communication with the slot 110 and together defines the accommodating hole 10. The length direction of the abutting rod 12 is the extending direction of the accommodating hole 10.
[0033] In the above implementation manner, the abutting rod 12 is used to abut against the shell and is also used to be connected with the detection piece body 11, so as to support the detection piece body 11 outside the shell. The slot 110 is arranged inside the detection piece body 11, is used to accommodate the shaft section to be detected, and is also used to contact the shaft section to be detected, so as to detect whether the length of the shaft section meets the theoretical requirement.

[0035] In combination with Figure 2 The abutting rod 12 is two, the two abutting rods 12 are connected with the one side edge of the detection piece body 11 where the slot 110 is located, and are respectively located on the opposite sides of the slot 110.
[0036] In the above implementation, the detection member body 11 is provided in a plate structure, and the abutting rods 12 are provided in two, so that the structure of the detection member 1 can be simplified, and the detection member 1 is convenient to manufacture. In addition, the detection member 1 is convenient to arrange outside the shell of the motor.

[0039] In the above implementation, the slot 110 is provided to include the insertion section 101 and the limiting section 102 which are communicated with each other along the extension direction of the slot 110, so that the shaft segment to be detected can be limited by the limiting section 102, so that the shaft segment detection tool can not be relatively deviated from the shaft segment to be detected during detection, thereby improving the detection accuracy. In addition, the shaft segment to be detected can be conveniently accommodated in the slot 110 through the insertion section 101 with a larger inner diameter, thereby improving the detection convenience.
[0040] In other examples, the inner diameter of the slot 110 can be greater than the outer diameter of the shaft segment to be detected, and the slot 110 can be in clearance fit with the shaft segment to be detected, which is not convenient for the shaft segment to be placed in the slot 110.

[0047] In the above implementation, the thickness of the detection member body 11 is set to be not less than the radius of the shaft section to be detected, so that the end of the shaft section to be detected can be in stable contact with the bottom wall of the accommodating hole 10 in the detection member body 11.
[0048] Optionally, the length of the abutting rod 12 is not greater than the depth of the slot 110.
[0049] In the above implementation, the length of the abutting rod 12 is not greater than the depth of the slot 110, so that the stability of the shaft section in the slot 110 can be improved.
[0050] Optionally, the shaft section detection tool is a metal plate.
[0051] In the above implementation, the shaft section detection tool is set to be a metal plate, so that the service life of the shaft section detection tool can be greatly prolonged.
[0052] Optionally, the shaft section detection tool is an integral structure.
[0053] In the above implementation, the shaft section detection tool is set to be an integral structure, so that the machining process of the shaft section detection tool can be simplified, and the manufacturing cost of the shaft section detection tool can be reduced.
[0054] In other examples, the shaft section detection tool can also be composed of a split structure, for example, the abutting rods 12 are connected together on one side of the detection member body 11 by welding.
[0055] The use process of the shaft section detection tool provided by the embodiment of the disclosure will be briefly introduced as follows:
[0056] When the shaft section detection tool is used to detect the shaft section of the output shaft located outside the shell, the detection plane 100 of the detection member 1 is first abutted with the shell where the output shaft to be detected is located;
[0057] Then, the shaft section to be detected is coaxially located in the accommodating hole 10.
[0058] Finally, whether the end face of the protruding end of the shaft section to be detected is in contact with the bottom wall of the accommodating hole 10 is observed by naked eyes. If the end face of the protruding end of the shaft section is in contact with the bottom wall of the accommodating hole 10, it indicates that the protruding length of the shaft section meets the theoretical requirement. If the end face of the protruding end of the shaft section is not in contact with the bottom wall of the accommodating hole 10 or the shaft section is difficult to be accommodated in the accommodating hole 10 (the length of the shaft section is greater than the hole depth of the accommodating hole 10), it indicates that the protruding length of the shaft section does not meet the theoretical requirement.
[0059] The above merely describes optional embodiments of the present disclosure, and is not intended to limit the present disclosure. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
