When being the application of the utility model specific embodiment, uses Fig. 5 the control circuit schematic diagram in the automatic processing system.

The specific embodiment

Below in conjunction with specific embodiment the utility model is specifically described.

Specific embodiment:

As shown in Figure 1 and Figure 2.This kind automatic tapping machine can be improved the back gained by the DJ-88 tapping machine that the male forever machinery plant in Shuande, Guangdong produces.Automatic tapping machine is made up of base 1, fuselage cradle, column 2, main shaft 3.Column 2 is supporting fuselage cradle, and fuselage cradle is made of entablature 4, sill 5.Main shaft 4 places that entablature 4, sill are 5 are equipped with clutch 6, clutch 7 and abutment sleeve 8 down.The below of last clutch 6 is connected with upper belt pulley, and the top of following clutch 7 is connected with down belt pulley, and two belt pulleys are relative, 8 control main shaft 3 liftings of positioning sleeve and last clutch, down clutch from close.Rotating shaft 9 is installed in the fuselage cradle, and 8 of rotating shaft 9 and abutment sleeves are connected with interlinked mechanism 10.As shown in Figure 4, an end of rotating shaft 9 is provided with at the inside recessed connecting hole 16 of axial direction, and connecting hole 16 is hexagonal configuration.But connecting hole 16 is connected with the power transmission shaft of the motor 11 of rotating.Motor 11 is fixed on the fuselage cradle by fixed head 17.The rotation of motor 11 control rotating shafts 9, thereby by 3 liftings of interlinked mechanism 10 control main shafts.Rotating shaft 9 other ends are fixed with L-shaped induction metal plate 12, are fixed with an inductor 15 on the fuselage cradle of sheet metal 12 belows.Sheet metal 12 and inductor 15 are sensors of a pairing.Sheet metal 12 is being followed rotating shaft 9 and is together being rotated, thereby inductor 15 can obtain the upper limit position of main shaft according to the position of sheet metal 12.Sill 5 is provided with the spacing adjustable limiting bolt 14 in main shaft lower position, and caging bolt 14 moves downward by the motion restriction main shaft 3 of restriction interlinked mechanism 10.Detecting the sensor 13 of main shaft lower position is located on the caging bolt 14.Whether sensor 13 contacts with caging bolt 14 by the trace 18 that detects interlinked mechanism, learns whether main shaft arrives the lower position.

As shown in Figure 5, the circuit of automatic control system is made of elements such as sensor, relay road, energization delay relays.

Operation principle: in the time of in automatic tapping machine being applied to automatic Jia Shi system, utilize control circuit manually to control also and can control automatically to tapping machine.When manually controlling, switch S 3 is pulled the below.When the S1 switch was pulled the left side, relay K 7 got electric, and rotating motor forward rotation drives the rotating shaft rotation descends main shaft, and tapping machine carries out tapping.When the S1 switch was pulled the left side, relay K 8 got electric, and rotating motor backward rotation drives the rotating shaft rotation rises main shaft, and tapping machine withdraws from tapping.And the charging action of switch S 2 control feed arrangements.When controlling automatically, switch S 3 is pulled the top.At this moment, the job step of system is as follows:

1, switch S 3 is pulled the top and is got to automated location, and the magnetic valve D1 that controls feed arrangement then gets electric, feed arrangement feeding then, and material is delivered to sensors X 3 places that limit the position then, sensors X 3 senders then, relay K 3 then.

2, relay K 3 gets, magnetic valve D1 outage, magnetic valve D2 are got, feed arrangement stops charging, and the cylinder of feed arrangement retreats, when the cylinder of feed arrangement falls back on the position of sensors X 4, it is electric that sensors X 4 senders get relay K 4, and magnetic valve D2 outage makes the cylinder of feed arrangement stop to return then.Simultaneously, relay K 3 electric make relay K 7 electric, time delays device KT begins the timing of switching on, motor M just changes then, the motor drives rotating shaft is rotated, main shaft descends then, the beginning tapping.

If the tapping of 3 main shafts time that time delays device KT sets imperfect tense, promptly main shaft in the time of setting when arriving the lower position with not ing, time delays device KT sender, relay K 6 self-locking, blank is controlled power supply, control circuit quits work.

When if the tapping of main shaft was finished in the time that time delays device KT sets, when to be main shaft arrive the lower position in the time of setting, the trace 18 of bindiny mechanism makes sensor 13 senders, relay K 1 must be electric then, relay K 7 outages then, and any action outage does not take place in time delays device KT then, relay K 8 gets simultaneously, motor M counter-rotating, main shaft is to rising, and tapping process stops to return.When main shaft rose to upper limit position, sheet metal 12 arrived inductors 15 places at this moment, thus upper limit position sensors X 2 senders.Then, relay K 2 electric, K8 outage then, motor M stops then, magnetic valve D1 gets electricly then, begins a new circulation.

The sensor of the sensor of detection main shaft upper limit position of the present utility model and detection main shaft lower position also can be located at other place.
