Y3150 gear hobbing machine control circuit

Commonly used in general production workshops and machine repair workshops, the Y3150 type gear hobbing machine is used: the machine is mainly based on the pre-mechanical mechanism, M1 is the tool holder motor
, for forward and reverse jogging and one-way starting operation; MZ is the cooling pump motor , the control line is in the middle of the control line from the special switch dance to the thin mushroom stop
    ! '
It has forward and reverse limit switches, and is equipped with low-voltage lighting and indicator light circuits. Figure 2-13a and b are the appearance and control circuit of
    the Y3150 gear hobbing machine . When the button SB1 is pressed during operation, the contactor KM1 is electrically closed, and the main contact is closed, causing the motor M1 to drive the tool holder to move downward . When it reaches the end point, it collides with the travel switch SQ2 and stops running. If the tool holder is required to move upward, press the start button SB4 to reverse the movement of the motor upward . If you need the main motor of the knife to move downward, press button SB3 to achieve the inching operation. - r. . √,
