The longitudinal feed control mechanism of the X6132 milling machine table is shown in the figure. The longitudinal feed movement of the table is controlled by the handle 23, and the microswitch SQ1 or SQ2 is pressed while the end face clutch M5 is turned on or off, so that the feed motor is rotated forward or backward to effect operation the vertical or leftward longitudinal movement of the table. The shaft 6 is provided with a spring 7 and a fork 5 for urging the clutch M5, and the force of the spring 7 causes the shaft 6 to move leftward to drive the fork 5 to the left by the clutch M5; the longitudinal feed movement of the table。 But also by the other side of the metal machine tool to manipulate the handle, pull the handle, the lever, pendulum on the pin 10, the lower end of the fork 9 so that the bump 2, the next swing.
When the handle 23 is pulled to the left, the pressing block 16 is swung to the left, the microswitch 22 (SQ2) is pressed, and the fork 14 is rotated clockwise while the feed motor is rotated in the opposite direction. The sleeve 2 is pivoted clockwise by means of a screw and the swing block 11 so that the projection 2 also oscillates clockwise and the highest point of the projection 2 leaves the left end face of the shaft 6, under the action of the spring 7, the shaft 6 is moved leftward to drive the fork 5 to the left and the clutch M5 is turned on to realize the longitudinal feed movement of the mill table to the left.
When the handle 23 is pulled from the left to the neutral position, the presser 16 loosens the jog switch 22 (SQ2) and the feed motor stops rotating; and the projection 2 oscillates counterclockwise and its highest point pushes the shaft 6 to the right , The clutch M5 is disengaged by the fork 5, and the longitudinal feed movement to the left is stopped.
Similarly, when the handle 23 is pulled from the left to the right position, the pressing block 16 presses the microswitch 17 (SQ1), and the feed motor rotates forward. At the same time, since the projection 2 is swung counterclockwise, the highest point is left The left end face of the shaft 6 is turned on again by the spring 7 clutch M5, thereby effecting the milling machine table to the right longitudinal feed movement.
