Abstract
A machine for truing the collectors or other rotating contact members of a motor, comprises a tool-holder carriage adapted to be fixed either against a brush-holder support associated with the collector or rotor, or against the face of the lower access opening of the casing of the motor, the engagement being provided by a connector coupled to the frame. Truing is effected by an abrasive stone driven in reciprocating motion along the collector. A double blowing and suction nozzle eliminates the dust. A brush and a sensor may be mounted on the carriage to eliminate the adherent dust and monitor eccentricity. The carriage is borne by a pivotable fork, by a parallelogram and by a double carriage rolling in a pit beneath the railway track.
Claims12
A machine for truing electrical connection members of a rotor rotatably mounted with respect to non-rotating casing parts of electrical machinery such as a traction motor, the machine having a tool holder system attachable to said non-rotating parts and comprising:
- a first carriage located between the machinery and supported to roll in a longitudinal direction;
- a second carriage supported on the first carriage and operative to roll in a transverse direction;
- a turret borne by the second carriage and operative to rotate about a vertical axis;
- arm means articulated at one end to the turret about a substantially horizontal axis;
- a first support articulated about a horizontal axis to the arm means at the other end thereof, and rotatable about a vertical axis;
- a second support articulated to the first support about a substantially horizontal axis;
- means for fixing the second support to a non-rotating part of the machinery;
- a tool-holder carriage borne by the second support to move with respect thereto in a substantially horizontal direction;
- means for driving the tool-holder carriage horizontally with a reciprocation motion;
- a grinding tool borne by said tool-holder carriage;
- and means for advancing said tool-holder carriage toward the rotor members to be trued.
