Description

Technical Field

[0001] The utility model belongs to the technical field of commutator processing, and in particular relates to a commutator inner hole patency detection device which can reduce extrusion damage when obstructed. Background Art

[0002] The commutator (English: commutator), commonly known as the commutator, is a component on a DC permanent magnet series-excited motor that allows the motor to continue rotating. When the coil passes through the current, it will rotate by attraction and repulsion under the action of the permanent magnet. When it turns to balance with the magnet, the contact piece on the commutator corresponding to the wire that was originally carrying electricity is separated from the brush, and the brush is connected to the contact piece corresponding to the group of coils that generate the driving force. This process is repeated continuously, and the DC motor starts to rotate. After searching, the "commutator inner hole patency detection mechanism" disclosed in the application number "CN202121524190.9" is also an increasingly mature technology. The first plug gauge is used to detect the inner hole from top to bottom, and the second plug gauge is used to detect the inner hole from bottom to top. In this way, the patency of the commutator inner hole is automatically detected to improve production efficiency. However, if the commutator inner hole is not smooth, the first plug gauge detects the inner hole from top to bottom, and the second plug gauge detects the inner hole from bottom to top, which will generate resistance and squeeze the commutator. At the same time, the commutator will be squeezed, and the excessive squeezing force will cause damage to the commutator. In view of this, we provide a commutator inner hole patency detection device that can reduce squeezing damage when blocked to solve the above problems. Utility Model Content
