Drawings
In order to more clearly illustrate the embodiments of the present invention, the drawings used in the embodiments will be briefly described below.
FIG. 1 is a schematic diagram of a dual head hole grinder apparatus.
Fig. 2 is a schematic diagram of the circuit of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
As shown in fig. 1, the left side is a double-head main power head 1 of the hole grinding machine, the right side is an auxiliary power head 2, the middle is a clamp 3, and a travel switch K is installed at a proper position of the auxiliary power head: when the cylinder drives the hole grinding needle to extend in place, the switch K is closed.
In order to overcome the electromagnetic interference of the electromagnetic relay and simultaneously maintain a plurality of control contacts, the invention adopts a combined control mode of controlling the electromagnetic relay by the solid-state relay, namely J11 controlling J1 and J22 controlling J2.
The initial state is: the cylinder retracts, the two motors M1 and M2 stop rotating, and the switch K is switched off.
The button SB is a jog switch, after being pressed, the normally closed contact is disconnected, the rear circuit is disconnected, Y1 is electrified, namely the cylinder extends out, after the cylinder extends in place, the travel switch K is closed, and the normally closed contacts of SB and SB are released to be closed;
after K is closed, the control end of the solid-state relay J11 is electrified, the J11 contact J11-1 is closed, the relay J1 is electrified, and in order to improve the anti-interference performance of the control end of J11, the control end of J11 is connected with R2C2 in parallel;
after the relay J1 is powered on, J1-1, J1-2 are closed, J1-3 is opened, J22 is powered on through R4, J22-1 is closed, J2 is powered on, and J2-3 is opened;
when the relay J1 is electrified, namely J1-1 is closed, the relay J1 is charged to the C1 through the R1, and the conduction of the Q1 is delayed, so that the Q1 is not conducted and the Y2 is not electrified before the J2-3 is disconnected, and the misoperation is prevented;
after J2 is powered on, J2-1 and J2-2 are closed, KM1 and KM2 are powered on respectively, and motors M1 and M2 are started.
When J1-2 is closed and J1-3 is opened, C3 is charged through R3, Q2 is conducted after voltage exceeds ZD and Q2 threshold voltage, a voltage regulator tube ZD is used for increasing threshold voltage and prolonging delay time, R5 is leakage current and preventing Q2 from being conducted mistakenly, and J1-3 is used for discharging a capacitor C3;
after a period of time delay, namely after the motor runs for a period of time, when Q2 is switched on, J22 loses power, J22-1 is disconnected, J2 loses power, J2-1 and J2-2 are disconnected, and the motors M1 and M2 stop running;
j2 is de-energized, J2-3 is closed, at the moment, because R1C1 is delayed properly, Q1 is already in an on state, when J2-3 is closed, Y2 is energized, the cylinder retracts, when the cylinder retracts, a travel switch K is triggered to be disconnected-J11 and J1 is de-energized-J1-1 is triggered to be disconnected, and because R1C1 is delayed, Q1 is delayed to be conducted until the cylinder retracts to the original position and is not cut off;
at this point, the device returns to the initial state.
