Description

Technical Field

[0001] The utility model relates to the technical field of commutator detection, in particular to a commutator inner hole spring sleeve detection mechanism. Background Art

[0002] The commutator is a key component in the armature of DC and AC commutator motors. It commutates the direction of rotation in the motor. Commonly known as the commutator, it commutates the current in DC and AC series motors, ensuring continuous rotation. The inclusion of a spring sleeve within the commutator improves structural stability and extends service life. However, during the commutator manufacturing process, the spring sleeve is installed by injection molding. This process can be prone to leaking, resulting in substandard commutators. Currently, there is no device capable of inspecting the spring sleeve within the commutator's inner bore. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a commutator inner hole spring sleeve detection mechanism to solve the above problems.

[0004] The technical solution of the utility model is implemented as follows: a commutator inner hole spring sleeve detection mechanism, comprising:

[0005] A testing platform, wherein a bracket is provided on the testing platform, and a testing station is provided on the testing platform for placing the commutator to be tested;

[0006] A lifting cylinder, wherein the lifting cylinder is fixedly mounted on the bracket;

[0007] A magnetic metal sensor connected to the telescopic shaft of the lifting cylinder;

[0008] Among them, the magnetic metal sensor is arranged above the detection station, and the central axis of the magnetic metal sensor coincides with the central axis of the commutator to be detected on the detection station. When the lifting cylinder is actuated, the lower end of the magnetic metal sensor is driven to descend and extend into the inner hole of the commutator to be detected.

[0009] By adopting the above technical solution, after the commutator to be inspected is moved and placed on the inspection station, the magnetic metal sensor is driven down by the lifting cylinder and extends into the inner hole of the commutator. Since the spring sleeve is made of metal, if there is a spring sleeve in the inner hole of the commutator, the magnetic metal sensor senses a metal signal, which means that the product has passed the inspection. If there is no spring sleeve in the inner hole of the commutator, the magnetic metal sensor cannot sense a metal signal, which means that the product has failed the inspection. This effectively detects whether there is a spring sleeve in the commutator, avoids the outflow of commutators with missing spring sleeves, and the inspection is very fast and convenient.

[0010] The utility model is further configured as follows: the sensing portion of the magnetic metal sensor is arranged around the lower end.

[0011] By adopting the above technical solution, when the magnetic metal sensor extends into the inner hole of the commutator, the spring sleeve is embedded in the inner wall of the inner hole, and the sensing part of the magnetic metal sensor is located around the lower end and can face the spring sleeve, thereby effectively improving the detection accuracy and effect.

[0012] The utility model is further configured to include:

[0013] A connecting plate is adjustably connected to the telescopic shaft of the lifting cylinder and is used to adjust the distance between the central axis of the telescopic shaft of the lifting cylinder and the central axis of the magnetic metal sensor.

[0014] By adopting the above technical solution, the distance between the magnetic metal sensor and the lifting cylinder can be adjusted through the connecting plate, so that the detection mechanism can adapt to commutators of various sizes and specifications.

[0015] The utility model is further configured as follows: a long strip of waist-shaped holes is opened on the connecting plate, the telescopic shaft of the lifting cylinder is connected to the waist-shaped holes by bolts, and the magnetic metal sensor is fixedly mounted on the connecting plate and is arranged downward.

[0016] By adopting the above technical solution, the telescopic shaft of the lifting cylinder can be moved in the waist-shaped hole after loosening the bolt, thereby adjusting the distance between the center axis of the telescopic shaft of the lifting cylinder and the center axis of the magnetic metal sensor. When it moves to the required distance, it is locked and fixed by the bolt, which is very convenient to adjust. BRIEF DESCRIPTION OF THE DRAWINGS

When it moves to the required distance, it is locked and fixed by the bolt, which is very convenient to adjust.
