Description

TECHNICAL FIELD

[0001] The application relates to the technical field of commutator detection, in particular to a positioning tool, a positioning mechanism and a detection device. BACKGROUND

[0002] The commutator is an important part of a motor, and whether the commutator is qualified is an important factor affecting whether the motor can normally work. Therefore, the produced commutator needs to be inspected to ensure that the commutator is in a qualified state. If the unqualified commutator is installed in the motor, the motor will be adversely affected.

[0003] REFERENCE Figure 1 The commutator comprises a shell 600 and a plurality of hooks 601. The shell 600 is provided with a plurality of commutator segments 604, the plurality of commutator segments 604 are arrayed along the circumferential direction of the shell 600, the plurality of hooks 601 are respectively arranged on the corresponding commutator segments 604, the plurality of hooks 601 are arrayed along the circumferential direction of the shell 600, a through hole 602 is formed in the shell 600, a shaft sleeve 603 is arranged in the through hole 602, and a boss 605 is arranged on the end face of the shell 600.

[0004] When the commutator is detected, the detection device is usually used to detect the performance of the commutator in multiple aspects, such as segment-to-segment detection, segment-to-shaft detection and height detection. The segment-to-segment detection and the segment-to-shaft detection need to be powered, and the related detection structure will be pressed on the commutator during the height detection.

[0005] In the related art, the detection device comprises a moving mechanism for driving the commutator to move and a segment-to-segment detection structure for segment-to-segment detection. The segment-to-segment detection structure comprises a plurality of detection strips, and the detection strips are electrically connected to the same loop in a group of two. The detection strips are in contact with the corresponding hooks on the commutator to detect whether the two adjacent commutator segments are conductive. The moving mechanism comprises a moving block, the moving block is provided with a groove, the groove is arc-shaped, the groove is provided for the hooks to be inserted, and a fixing bead is arranged in the groove, and the end of the fixing bead extends into the adjacent two hooks.

[0006] The moving block is driven to move towards the commutator, the end of the fixing bead extends into the adjacent two hooks, the shell is fixed in the groove, the moving block is driven to move in the detection device, the commutator is moved to the next detection structure, then the moving block is separated from the commutator, and finally the moving block is reset.

[0007] When the diameter of the groove is the same as the diameter of the commutator, the small commutator is easily driven by the groove wall due to the small weight of the small commutator. However, the diameter of the groove needs to be larger than the diameter of the commutator to ensure that the moving block will not drive the commutator to move when the moving block is separated from the commutator.

[0008] When the moving block drives the commutator in the vertical state to move, the commutator generates inertia of movement. Since the head of the commutator is heavier than the tail, the center of gravity of the commutator is above, and the moving block exerts a force on the upper part of the commutator, so that the upper part of the commutator is not in a vertical state with the lower part of the commutator. In addition, the diameter of the groove is larger than the diameter of the commutator, so that the commutator has a place to tilt. When the moving block is separated from the commutator, the commutator is prone to tilting, so that the positioning between the commutator and the detection device is inaccurate, which affects the detection result of the detection device on the commutator, and the unqualified commutator is easily detected as a qualified commutator, which finally causes damage to the motor.
