The rocker arm lifting motor 17 rotates to drive the screw nut 15 to move, the screw nut 15 drives the cylinder 14 to move on the outer upright post 11, the rocker arm 4 is driven to move, and the safety nut is arranged at the top end of the screw nut 15, so that the rocker arm 4 can be prevented from falling. The swing arm 4 must be clamped to the outer column 11 during rotation and be able to rotate 360 degrees outside the inner column 13.
The base 1 is further provided with a hydraulic pump motor 18 and a cooling liquid motor 19, the hydraulic pump motor 18 is connected with a clamping device, and the clamping device is arranged between the outer upright post 11 and the inner upright post 13, and between the outer upright post 11 and the cylinder 14.
Install headstock 6 on the horizontal rail of 4 one ends of rocking arm, install main shaft 3 in the headstock 6, rotary part and main shaft feeding and speed change mechanism are installed to main shaft 3, a spindle motor 16 is installed to headstock 6 upper end, spindle motor 16 is connected with rotary part, speed change mechanism, the 5 outsides of headstock are provided with control panel 5, control panel 5 is connected with the singlechip, the singlechip is connected with the controller electricity, the controller is connected with rocking arm elevator motor 17, hydraulic pump motor 18, coolant liquid motor 19 and spindle motor 16, the headstock outside still is connected with a hand wheel 12, hand wheel 12 is connected with main shaft 3.
The main spindle head 6 contains the main spindle 3 and its rotary parts and spindle feed and speed change mechanisms, which drive the main spindle 3 to perform the main movement of the radial drilling machine. The headstock 6 is mounted on a horizontal rail of the swing arm 4, and an operator can move the headstock by himself when the radial position of the headstock 6 needs to be changed during machining. Thus, by moving the headstock 6 on the swing arm and rotating the swing arm 4, the spindle 3 can be very easily adjusted to a proper position required for machining. When a metal workpiece is machined, the outer upright post 11 and the inner upright post 13 are clamped, the rocker arm 4 and the outer upright post 11 are clamped, the spindle box 6 and the rocker arm 4 are clamped, next machining operation can be carried out, and clamping and releasing are achieved by driving a clamping device through a hydraulic motor.
A control panel 5 is arranged on the outer surface of the spindle box 6, a button on the control panel 5 is electrically connected with a single chip microcomputer, and the single chip microcomputer is electrically connected with a contactor (for controlling the starting of a motor) and a plurality of sensors (such as a limit switch, a Hall sensor and the like). As shown in fig. 2, the control panel 5 is provided with a main brake 51, a spindle motor stop button 56, a spindle motor start button 57, a column/headstock clamping button 55, a column/headstock release button 54, a rocker arm raising button 53, and a rocker arm lowering button 52.
Fig. 3 is an I/O distribution diagram of the present invention, fig. 4 is a circuit diagram of the present invention, the model of the single chip microcomputer is AT89C51, when a workpiece is machined, the main gate 51 on the control panel 5 is opened first, and after the workpiece to be machined is fixed, the rocker arm needs to be adjusted. The following takes the lifting process of the rocker arm as an example: when a rocker arm rising button SB3 on the control panel 5 is pressed, the single chip microcomputer sends an instruction to enable a hydraulic pump motor M3 forward contactor KM4 to be powered on, an oil-tight circuit of the rocker arm is switched on, the hydraulic pump outputs pressure oil to the rocker arm through an electromagnetic valve, the rocker arm is released, and a signal is obtained when the rocker arm releases a limit switch SQ 2. Then the forward contactor KM4 loses power, M3 stops rotating, then the forward contactor KM2 of the rocker arm ascending/descending motor M2 is electrified, the rocker arm starts to ascend, when the rocker arm ascends to a specified position, the SB3 is released, the KM2 loses power, the reverse contactor KM5 of the hydraulic pump motor M3 is electrified, reverse pressure oil is output to the rocker arm, and the rocker arm is clamped. When the rocker is clamped, the rocker clamping limit switch SQ3 is signaled, the M3 reverse contactor is de-energized, the M3 stops rotating, and the rocker lifting process is finished.
Loosening and clamping processes of the spindle box/the upright: the spindle box/upright post release button SB5 is pressed down, the tightness oil circuit of the spindle box/upright post is connected, the single chip microcomputer sends out an instruction to enable the forward contactor KM4 of the hydraulic pump motor M3 to be powered on, the M3 rotates forwards, the spindle box/upright post is released, after the spindle box/upright post is in place, the limit SQ4 of the spindle box/upright post obtains information, the KM4 is powered off, the forward rotation of the M3 stops, and the indicator lamp HL1 is on. The rocker arm is manually adjusted to rotate, and the main spindle box moves to a proper position along the radial direction of the rocker arm. When the clamping button SB6 is pressed, the indicator lamp HL1 is turned off, the reverse contactor KM5 of the hydraulic pump motor M3 is electrified, the M3 is reversely rotated, and the spindle box/upright post is clamped. When the hydraulic pump is in place, the clamping limit switch SQ4 obtains information, the KM5 loses power, the M3 is turned reversely and stops, the indicator lamp HL2 is lightened, the rocker arm is clamped again, and a driving circuit of the hydraulic pump motor M3 is shown in figure 5.
To ensure safety when machining a workpiece, each section must have a delay of 2-3 seconds after the end of the run from the next section.
In the processing process, the rotating speed of the spindle motor 16 and the descending height of the spindle 3 can be seen through monitoring software of the upper computer. The rotation speed monitoring of the spindle motor 16 is realized by a hall sensor, the circuit diagram is shown in fig. 6, namely, a magnet is fixed at the rotating part of the motor, a hall switch is arranged at the periphery of the movement track of the magnet, the hall switch periodically senses magnetic lines of force when the motor rotates to generate pulse voltage, the pulse is counted within a certain time, the rotation speed of the motor can be converted, and the real-time rotation speed of the motor is displayed on upper computer software by a singlechip. The descending height of the main shaft 3 is calculated by the rotation angle of the hand wheel 12, because the feeding movement of the main shaft 3 is controlled by the hand wheel 12, the main shaft is fed downwards by rotating the hand wheel 12, and the larger the rotation angle of the hand wheel 12 is, the more the main shaft 3 descends. The single chip microcomputer obtains the descending depth through calculation and displays the descending depth on an upper computer in real time. Through the monitoring of the rotating speed and the descending depth of the main shaft 3, the workpiece can be conveniently and accurately machined.
