Adopt after technique scheme, PLC controller can be according to the action of the testing result control hydraulic motor of two position-detection sensors, and then realizes automatic indexing, thereby has reduced operating personnel's labour intensity, has improved working (machining) efficiency.The utility model is simple in structure, low cost of manufacture, and calibration accuracy is high.
Brief description of the drawings
Fig. 1 adopts according to the structural representation of the milling machine of the automatic indexing mechanism of the utility model one embodiment.
Fig. 2 is the schematic block circuit diagram of the utility model milling machine automatic indexing one embodiment of mechanism.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is made further instructions.
Fig. 1 shows and adopts according to the structural representation of the milling machine of the automatic indexing mechanism of the utility model one embodiment.This milling machine comprises reciprocally mobile workbench 1, milling cutter 2, main spindle box 3 and tailstock 4.Main spindle box 3 be provided with main shaft (not shown) and be connected with above-mentioned main shaft, for clamping the fixture (not shown) of one end of part 5, tailstock 4 is provided with the thimble 41 of the other end that withstands part 5.
Shown in Fig. 2, comprise PLC controller 61, hydraulic motor 62, hydraulic motor control circuit 63, gear drive 64, whether move to the primary importance sensor 65 in precalculated position and whether turn over the second place sensor 66 of predetermined corner for detection of described main shaft for detection of workbench 1 according to the milling machine automatic indexing mechanism of the utility model one embodiment.
The control output end of PLC controller 61 is connected with the control input end of hydraulic motor control circuit 63, can control by this hydraulic motor control circuit 63 action of hydraulic motor 62.Hydraulic motor 62 is connected with spindle drive by gear drive 64.The signal output part of primary importance sensor 65 and second place sensor 66 is all connected with the signal input part of PLC controller 61.
In a specific embodiment, hydraulic motor control circuit 63 is made up of several relays, contactor and magnetic valve.Gear drive 64 comprises that intermeshing the first gear 641 and the second gear 642, the first gears 641 are connected with the output shaft of hydraulic motor 62, and the second gear 642 is connected with main shaft.Primary importance sensor 65 is the first approach switch, and the sensor block 13 that can be sensed by the first approach switch in the time that this workbench 1 moves to above-mentioned precalculated position is installed on workbench 1.Second place sensor 66 is the second approach switch, and the disk 32 that can rotate with this main shaft is installed on main shaft, and the side of this disk 32 is provided with the sensor block 33 that can be sensed by the second approach switch in the time that described main shaft turns over predetermined corner.
Below taking processing generator shaft as example illustrates the course of work of the present utility model.After operating personnel complete a Pocket Machining on generator shaft side, carry out withdrawing operation, in the time that workbench 1 moves to precalculated position, the sensor block 13 on workbench 1 is sensed by the first approach switch, and the first approach switch sends to PLC controller 61 signal that puts in place.PLC controller 61 receives that this puts in place after signal, control hydraulic motor 62 by hydraulic motor control circuit 63 and rotate, hydraulic motor 62 is driven main shaft, is rotated together with the generator shaft of the disk 32 that is connected with main shaft and the fixture clamping that is connected to main shaft by gear drive 64.In the time that main shaft turns over predetermined corner (for generator shaft, this predetermined corner is 180 °), the sensor block 33 on disk 32 is sensed by the second approach switch, and the second approach switch sends to PLC controller 61 signal that puts in place.PLC controller 61 receives that this puts in place after signal, controls hydraulic motor 62 and stops operating, thereby realize automatic indexing by hydraulic motor control circuit 63.
