Description
Technical field:
The utility model relates to a kind of adjustable turn-to-turn withstand voltage test frame, can be supporting with the withstand voltage instrument of rotor turn-to-turn, be used for carrying out rotor turn-to-turn voltage-withstand test, and belong to electric tool rotor turn-to-turn voltage-withstand test technical field.
Background technology:
Single phase series motor is the heart of electric tool, its quality good or not plays a crucial role to normal use of electric tool, electric tool is when manipulating, the insulation system of single phase series motor is subjected to the combined action of high temperature and high mechanical stress and is fragile, in order to improve the insulation quality of single phase series motor, should strengthen the on-line testing of single phase series motor rotor in manufacture process, the withstand voltage test of single phase series motor rotor is one of main contents of rotor on-line testing, during rotor turn-to-turn withstand voltage test at present, normally measured rotor is clipped on the anchor clamps of the withstand voltage instrument of rotor turn-to-turn, respectively head on epitrochanterian a slice commutation sheet with two probes then, form the loop, when surveying second, two probes are shifted to another adjacent commutation sheet separately successively, so analogize, finish until all commutation built-in testings, there is following shortcoming in such test:
1. test speed is slow;
2. the different rotor commutation sheet of diameter will change different probes;
3. different axle head diameters will be with different anchor clamps.
Summary of the invention:
The purpose of this utility model is invented a kind of can test fast automatically, need not to change probe and anchor clamps exactly, with the supporting turn-to-turn withstand voltage test frame of the withstand voltage instrument of rotor turn-to-turn.
For realizing above purpose, the technical solution of the utility model provides a kind of turn-to-turn withstand voltage test frame, its characteristics are, it is by front rack, the conducting strip support, conducting strip, crank base, motor, crank, driving wheel, tail-bracket, base plate, running roller, lead, spring, bracket base is formed, the top is equipped with the front rack of two running rollers that can support testpieces respectively, tail-bracket is fixed on the left side of base plate center line, the right side, the conducting strip of semicircular in shape groove props up the inboard that is placed on front rack, the center of circle that makes semi-circular recesses is at front rack, on the center line of tail-bracket, bracket base is used the inboard of Bolt Connection conducting strip support, and be fixed on the upper end and the same plane of conducting strip support upper end of base plate upper roll wheel, two conducting strips that can move forward and backward place in the conducting strip bracket chute, the spring that conducting strip is resetted places in the inside groove of conducting strip support, one end of spring withstands conducting strip, draw lead on the conducting strip, crank base places the rear side in the middle of front rack and the tail-bracket and is fixed on the base plate, rotate before and after being connected in crank base with pin and making crank the lower end of crank, the left side of crank upper end is equipped with motor, the right side is equipped with driving wheel, and driving wheel is rotated by driven by motor.
The withstand voltage test of single phase series motor rotor is achieved in that
1. the two ends with measured rotor rest between two running rollers of front rack, tail-bracket, a simultaneously epitrochanterian circle commutation sheet with two conducting strips separately because conducting strip withstands spring, therefore two conducting strips can tightly touch the two ends of commutation sheet;
2. putting down crank makes driving wheel contact with the iron core cylindrical of rotor;
3. the pulse high-voltage of turn-to-turn withstand voltage test is applied on the commutation sheet of measured rotor by lead, conducting strip;
4. the direct current of the withstand voltage instrument of rotor turn-to-turn is by the motor-driven driving wheel simultaneously, and driving wheel drives measured rotor again and rotates;
5. rotate a circle, conducting strip just can touch epitrochanterian each piece commutation sheet, promptly finishes the turn-to-turn withstand voltage test to each piece commutation sheet of measured rotor.The utility model has the advantages that:
1. speed is fast, and just can finish test 1 second;
2. do not need anchor clamps, do not change the phase changer that probe just can be tested different size automatically.
