Problems solved by technology

Most of the existing motor commutator detection devices are imported from abroad, and the price is expensive. So far, there is no motor commutator detection device with high precision and low price in China.
When testing the insulation performance of the motor commutator, during the rotation of the motor commutator, electric sparks will be generated when the metal sheet contacts the high-voltage electrodes, and instantaneous high voltage will be generated, which will easily burn out the data acquisition system
When testing the radial circular runout of the motor commutator, due to the manufacturing error of the rotary table itself that drives the motor commutator to rotate, the swing arm line will jump, so it brings great difficulties to the detection of the radial circular runout of the motor commutator. error

Abstract

The invention provides a motor commutator detection device. The device comprises a revolving platform part, a double-headed electrode part, a transverse moving mechanism, an up and down moving mechanism and a radial measurement part. When the device measures, the motor commutator is fixed on the revolving platform part, and rotates with the revolving platform; the double headed electrode part is fixed on an extending front arm of the transverse mechanism, and is used for applying high voltage to certain two metal plates of the commutator to perform a high voltage test; and a test head of the radial measurement part is closely attached to the commutator, and is used for measuring radial circular run-out of the commutator. The commutator detection device has a simple measurement process and high measurement accuracy, and can measure a plurality of technical parameters of commutators with different sizes (the diameter is less than or equal to 400mm).

Description

technical field [0001] The invention belongs to a motor commutator detection device, which is used to detect the insulation performance and geometric accuracy of the motor commutator, mainly by applying a high voltage between two electrodes of the motor commutator, and measuring the distance between the two electrodes. The electric current is used to test its insulation performance; the radial circular runout of the motor commutator is measured by a linear sensor. Background technique [0002] The motor commutator is a part of the DC permanent magnet series motor to allow the motor to continue to rotate. At present, there is no better method for detecting the electrical parameters of the motor commutator. Most of the existing motor commutator detection devices are imported from abroad and are expensive. So far, there is no motor commutator detection device with higher precision and lower price in China. When testing the insulation performance of the motor commutator, during...
