Description
Technical field
The present invention relates to the armature insulation voltage-resisting test apparatus of withstand voltage properties between each commutator segment for testing armature of direct current motor and insulating property.
Background technology
Armature is the core component of direct current generator, and its structure and manufacturing process are quite complicated, so be necessary to detect armature performance before assembling, the withstand voltage properties between each commutator segment and insulating property are its main test items.Withstand voltage properties between each commutator segment of current detection and the method for insulating property as follows: first, two probes are contacted (probe is connected with cylinder piston) with second commutator segment with first commutator segment respectively, then apply voltage to commutator segment is tested, after testing, unclamp probe, armature is driven to rotate the angle of a commutator segment by a drive unit, then two probes are made to contact with second commutator segment and the 3rd commutator segment respectively, then apply voltage to commutator segment is tested, circulation is tested successively, until when the withstand voltage properties tested between all adjacent commutator segments and insulating property.Next, adjust the angle between two probes, two probes are contacted with first commutator segment and the 3rd commutator segment respectively, then apply voltage to commutator segment is tested, after testing, unclamp probe, armature is driven to rotate the angle of a commutator segment by a drive unit, then two probes are made to contact with second commutator segment and the 4th commutator segment respectively, then apply voltage to commutator segment is tested, circulation is tested successively, until when withstand voltage properties between the commutator segment testing all a slices of being separated by and insulating property.Next, then according to method above test all two panels of being separated by, three ... commutator segment between withstand voltage properties and insulating property, until when the withstand voltage properties tested between any two panels commutator segment and insulating property.In the test process of prior art, there is following feature: (1) can only test withstand voltage properties between the two panels commutator segment of constant spacing and insulating property at every turn.(2) when needs change spacing, the angle between probe must be adjusted.(3) in each test process, need probe and commutator segment are contacting and separating, therefore, cylinder piston must stretch out and retract.(4), after each test process completes, after the angle of a commutator segment must being rotated by a drive unit drive armature, just can test next time.(5) when tested armature rotating mechanism precision is not high, easily cause commutator segment and probes touch bad, upon application of a voltage, cause probes touch partial melting because contact resistance is excessive, and vestige is remained on commutator, affect serviceable life and the product quality of probe.Often complete in a commutator segment performance test process, cylinder piston must complete and stretch out and retract action, and armature need rotate an angle under the drive of rotating mechanism, and testing efficiency is low; When carrying out the test of any commutator-segment insulation withstand voltage properties, adjust very inconvenient; For avoid commutator segment and probes touch bad, require high to the rotation precision of armature rotating mechanism.
