The invention discloses a transmission shaft assembly mechanism of a direct transmission group assembly device, which is characterized in that it includes a vibrating plate for the transmission shaft, a first conveying pipe, a material receiving positioning seat for the transmission shaft, and a transplanting mechanism for the transmission shaft; The material-receiving positioning seat includes a base and a material-receiving assembly, and the material-receiving assembly includes a material-receiving bump, a material-receiving slider, a traverse cylinder for the material-receiving slider, and a jacking cylinder for the transmission shaft; the lower surface of the material-receiving slider and There is a jacking interval between the lower sides of the socket, and the height between the upper surface of the receiving slider and the lower side of the socket is consistent with the shaft length of the transmission shaft; the upper end of the first conveying pipe and the transmission shaft use a vibration plate The discharge port of the first delivery pipe is connected, and the lower end of the first conveying pipe is connected with the blanking hole on the material receiving bump. The transmission shaft assembly mechanism of the direct transmission group assembly device of the present invention has the advantages of being able to effectively ensure the orderly output and precise positioning of the transmission shafts one by one, and help realize high-precision assembly of the transmission shaft.

The invention discloses an assembly error ultrasonic detection method, by setting two ultrasonic detection point groups, and setting at least two ultrasonic detection points at intervals in each ultrasonic detection point group, thus, using the same ultrasonic detection point group The energy amplitude of the ultrasonic echo signals at different ultrasonic detection points can directly determine whether there is a rotation error between two assembly workpieces, and the average value of the energy amplitudes of the ultrasonic echo signals of the two ultrasonic detection point groups In this case, it can be judged whether there is a translation error between two assembled workpieces, that is, the assembly error ultrasonic detection method of the present invention can accurately detect the type and direction of the assembly error, and can be used to guide the operator to complete the high-precision assembly work.

The invention relates to a stripe image converter tube racking tool, which comprises a pair of circular tube formed by mutually buckled, a first end cover and a second end cover arranged on two ends of the circular tube, and a first locating device and a second locating device arranged coaxial to the circular tube, wherein annular steps with the number being equal to the number of electrodes in an image converter tube are arranged on an inner wall of the circular tube; axial positions of the annular steps are determined according to positions of the electrodes in the image converter tube; and inner holes of the annular steps are matched with the matched electrodes. According to the racking tool, the position accuracy including axial deviation, radial deviation, coaxiality and the like in a stripe tube racking process can be improved; an uncontrollable process link and manual operation are reduced, so that the consistency of racking is improved; and the efficiency for manufacturing stripe tubes and the yield are improved.
