Detection device for tensioning of motor rotor guide bar

The invention belongs to the technical field of motor rotor conducting bar detection, and particularly relates to a motor rotor conducting bar tensioning detection device which solves the technical problems in the background technology and comprises an upper pressing plate, a fixed supporting base and a vertical pushing oil cylinder. The upper pressing plate and the lower pressing plate are symmetrically arranged up and down, the center of each of the upper pressing plate and the lower pressing plate is provided with a through hole with the same size as a motor rotor vent hole, each of the upper pressing plate and the lower pressing plate is provided with a plurality of bolt holes with symmetrical positions, a double-thread screw penetrates through each pair of bolt holes with corresponding positions, and the two ends of the double-thread screw penetrate through the upper pressing plate and the lower pressing plate and then are matched with fastening nuts; the piston end of the vertical pushing oil cylinder is arranged upwards, the piston end of the vertical pushing oil cylinder is connected with a positioning block used for being connected with a guide bar in a clamping mode, and an oil cylinder supporting base is arranged at the bottom of the vertical pushing oil cylinder. According to the invention, the accurate value of the tensioning strength of the conducting bar can be rapidly detected, the rotor iron core is not damaged, and the rotor iron core can be continuously used after detection is completed.
