At this time, the square-structured gear output shaft 23 arranged on the square-structured gear output shaft positioning platform is pushed into the motor housing 14 through the sliding block 8 to be meshed with the rack assembly 33 and finish centering installation, so that the operation is convenient and the structure is simple. The specific control mode is as follows: the vertical air cylinder firstly vertically compresses the motor shell and the air cylinder, secondly, the ventilation starts two groups of compressing air cylinders to compress the end face of the air cylinder which is arranged in the upper semicircular groove in the transverse direction, finally, the two groups of centering air cylinders transversely push the rack to form a centering position, and the gear output shaft of the longitudinal pushing square structure is meshed with the rack to form a centering position, so that the control sequence is vertical-transverse-longitudinal.
The centering installation device for the gear output shaft of the square structure of the wiper is formed by simultaneously and reversely moving and pushing the racks in the motor shell through the piston rods of two groups of centering cylinders in the pneumatic principle control device, when the piston rods of the two groups of centering cylinders simultaneously move to equal displacement, the racks in the motor shell reach the middle position relative to the motor shell, and meanwhile, the gear output shaft of the square structure is installed in the motor shell in a limiting manner through being meshed with the racks, so that the gear output shaft of the square structure can be ensured to be at the middle position of the racks after being installed, and the centering positions of the racks and the gear output shaft of the square structure are achieved, so that the centering control device is particularly suitable for centering control of the pneumatic wiper for locomotives and motor trains.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
