Abstract
The invention discloses a shaft deformation detection device of three or four gear shifting fork shaft. The device comprises a detection platform and a controller. A rotation drive mechanism is arranged on the detection platform, and comprises a servo motor which is fixed on the detection platform and a bracket. The bracket is pivoted with a transmission wheel in belt transmission with the servo motor. A fixing structure which is used for fixing one end of the three or four gear shifting fork shaft is arranged on a driven wheel coaxial with the transmission wheel, wherein the center line of the shaft coincides with the center line the of the driven wheel. A detection mechanism is arranged on the detection platform, and contacts the other end of the three or four gear shifting fork shaft to detect shaft deformation. The servo motor and the detection mechanism are respectively electrically connected with the controller. The device has the advantages that the rotation drive mechanism drives one end of the three or four gear shifting fork shaft to rotate around the shaft center line; the detection mechanism on the other end can detect whether the welded shaft is deformed; and after the controller receives the data of the detection mechanism, the rotation drive mechanism is controlled to enable the three or four gear shifting fork shaft to rotate to a deformation direction, which is convenient for follow-up correction of an operator.
