The horizontal and vertical feed control mechanism of the X6132 horizontal universal milling machine table is shown in the figure. Handle 1 has upper, lower, front, rear and middle five working positions. When the handle 1 is moved forward and backward, the drum is driven by the ball at the front of the handle to move left and right axially. When the handle 1 is moved up and down, the drum 9 is rotated back and forth within a certain range by the flat groove on the hub body 3, the flat key 2 and the shaft 4.
On the circumference of the drum 9, the grooves with bevels control the micro switches SQ3, SQ4, SQ7 and SQ8, respectively. Where SQ8 is used to control the opening or disconnection of the electromagnetic clutch M5, which is used to turn on or off the electromagnetic clutch M4, i.e., to turn on or off the vertical feed motion and the lateral feed motion, respectively. SQ3, SQ4 is used to control the forward and reverse rotation of the feed motor, so that the milling machine table is moved forward, down and backward.
When the handle 1 is pulled forward, the drum 9 is moved axially to the left, and the bevel on the drum presses the lower pin 7 and acts on the microswitch SQ3 to turn the feed motor forward. At the same time, the pin 5 on the drum circumference, acting on the microswitch SQ7, so that the lateral feed electromagnetic clutch M4 through the power to work, so as to achieve the mill machine tool table forward horizontal feed movement.
When the handle 1 is pulled back, the drum 9 is moved axially to the right, the bevel on the drum presses the lower pin 8, acts on the microswitch SQ4, reverses the feed motor; the pin 5 is still in the drum round on the circle, so that the electromagnetic clutch M4 through the work of compact, to achieve the back of the table horizontal feed movement.
When the handle 1 is moved to the upper position, the drum 9 is rotated in the counterclockwise direction, and the inclined surface thereon is pressed against the pin 8 to act on the microswitch SQ4 to reverse the feed motor; the pin 6 is on the drum circumference , the lower pin 6 is pressed and acted on the microswitch SQ8 so that the electromagnetic clutch M3 is energized and pressed to achieve the upward movement of the machine table.
When the handle 1 is pulled down, the drum 9 is rotated in the clockwise direction, and the inclined surface thereon is pressed against the pin 7 to act on the microswitch SQ3 so that the feed motor is rotated forward; the pin 6 on the drum circumference is pressed, so that the micro-switch SQ8 work, so that the electromagnetic clutch M3 power on the work, to achieve the milling machine table down the feed movement.
When the handle 1 is pulled to the middle position, the top pins 8 and 7 are in the groove of the drum, the freckers SQ4 and SQ3 are released, the feed motor stops rotating, and the pins 5 and 6 are also in the drum slot, release the micro switch SQ7, SQ8, so that the electromagnetic clutch M4 and M3 power off, so the milling machine table front and rear feed movement and the upper and lower feed all stop.
