(1) motion of the in the vertical direction of the relative workbench of instrument magnetic pole is controlled elevating mechanism 21 and the manually common realization of control lifting platform mechanism automatically by main shaft, the power source that main shaft is controlled elevating mechanism 21 automatically is servomotor 79, the power of servomotor 79 outputs passes to leading screw 86 by connecting shaft cover 80 and key 81, leading screw 86 cooperates together with nut 87, thereby the rotation of leading screw 86 is converted into moving up and down of nut 87, nut 87 is fixed on the sliding sleeve 64 by nut seat, sliding sleeve 64 is fixed on the main shaft 65, main shaft 65 is fixed together by magnetic core clamping device 17 and electromagnetism rubbing head 16 again, thereby has realized moving up and down of electromagnetism rubbing head 16; Regulate by manpower and manually control lifting platform mechanism, when manpower acts on manual axle 38, manually axle 38 rotates, manually axle 38 sends power to bevel gear 43 by key 42 and nut 44 again, because bevel gear 43 is meshed with bevel gear 45, and bevel gear 45 is fixed on the screw rod 51 by key 47 and nut 46, historical facts or anecdotes has showed the rotation of screw rod 51, screw rod 51 is connected with nut 50, and nut is fixed on the base 1, therefore screw rod 51 not only rotates but also is moving up and down, screw rod 51 is fixed on the table base 2 by taper roll bearing 48 and bearing gland 49 again, and the compound motion of screw rod 51 is converted into moving up and down of workbench 34 thus.The motion of the in the vertical direction of the relative workbench 34 of instrument magnetic pole moves up and down and the common realization of moving up and down of workbench 34 by electromagnetism rubbing head 16.
(2) power source of main shaft lengthwise movement is servomotor 27, servomotor 27 sends power to the gear 24 that is fixed on its output shaft, because gear 24 is meshed with gear 29, and gear 29 is fixed on the leading screw 22, therefore power is sent on the leading screw 22, by the cooperating of leading screw 22 and nut, the rotation of leading screw 22 is changed into the movement of main spindle box 11, thereby realized vertically moving of main spindle box 11 again.
(3) the workbench transverse shifting is driven by servomotor 53, servomotor 53 is by exporting lower rotating speed and larger torque behind gearbox 62 reductions of speed, gearbox 62 sends power to leading screw 4 simultaneously, by sending power to workbench 34 with cooperating of nut 3, workbench 34 is just laterally mobile on dovetail guide 35 again for leading screw 4.
(4) Renewal process of magnetic abrasive is:
The automatic replacing of magnetic abrasive is controlled by timer, and regularly change interrupt service routine the replacing of magnetic abrasive is controlled, thus the automatic replacing of realization magnetic abrasive.
After main program started, work step was made as 1, pass is made as 1, and abrasive material is regularly changed program initialization; Change abrasive material, abrasive material is regularly changed the time zero clearing; Please be with processing working procedure; Set pass; Set work step; Completion of processing is then put back to magnetic abrasive abrasive material storehouse, timeing closing interrupt service routine.If undressed complete, then continue the operation pass and add 1, pass also added 1 when perhaps work step added 1, until completion of processing.
The replacing of concrete abrasive material of the same race is carried out according to timing mode: the abrasive material in the control system is regularly changed the timing of interrupt service routine control timer, after arriving process time, control system just forces process to be suspended, and turns and carry out interrupt service routine.Interrupt service routine control tool magnetic pole 94 moves to the top of useless abrasive material bucket 9c in the magnetic abrasive storehouse 9, cuts off the electric current of solenoid 97, makes instrument magnetic pole 94 lose magnetic force, and magnetic abrasive just can fall into useless abrasive material bucket 9c automatically.Then according to current work step number, control tool magnetic pole 94 moves in the corresponding abrasive material bucket, solenoid 97 is connected weak current, and (size of this electric current mixes up in advance, make magnetic pole absorb a certain amount of magnetic abrasive material) circuit, allow instrument magnetic pole 94 be drawn onto abrasive material, then move certain distance on the control tool magnetic pole 94, automatically switch to again heavy-current line, allow magnetic pole that the magnetic abrasive material is sucked.Last control tool magnetic pole 94 moves to the original place, the processing of proceeding to interrupt.Every certain process time, abrasive material can be changed once automatically like this.
The not replacing of abrasive material of the same race: add man-hour whenever a work step finishes, control system will control tool magnetic pole 94 moves to the top of abrasive material bucket 9b, the abrasive material of absorption all will be put back among the original abrasive material bucket 9b automatically, and then move in the corresponding abrasive material bucket of new work step, solenoid 97 is connected the certain magnetic abrasive of weak current absorption, after moving certain distance on the control tool magnetic pole 94, automatically switch to again heavy current, so just finished the automatic replacing of abrasive material.
(5) complex-curved digital scanning is measured and programming:
The level that can cause measuring-signal when gauge head contacts with surface of the work changes.When gauge head does not contact workpiece, since the not conducting of light emitting diode of photoisolator, the phototriode cut-off, and the level of exporting to LPT 8255 is high level.When gauge head and workpiece (must be metalwork) Surface Contact, the light emitting diode conducting, phototriode is conducting also, exports to 8255 signal and just becomes low level by high level.Gauge head lifts, and output level can become high level again.When the level of photoisolator output was low level, control system was carried out record to the coordinate of probe location, thereby obtains the coordinate of a measuring point.
Gage outfit is by a side setting in motion during measurement, and gauge head moves down under the automatic control of control system, and when touching workpiece, it is mobile that gauge head stops, and then the current coordinate of system's register gauge head raises gauge head the displacement h of regulation
0, then moving to opposite side, gauge head whenever moves and moves a step, and control system all will detect gauge head and whether contact surface of the work, if contact then stops to move to right and records the position coordinates of gauge head, moves distance h on then
0, continue again mobile.If gauge head mobile regulation apart from l0 the time, still do not contact workpiece, then also to stop to move to right, move down and transfer to, touch workpiece, record probe location coordinate.So measure, until surveyed all paths of procedure stipulation.
In the process of measuring, the centre of sphere track of gauge head is on the equidistant surface of contour surface, adopt the radius of conductive contact to equal magnetic pole Probe-radius and machining gap sum, the formed track of measuring point line then, just can be used as the track that moves when the instrument magnetic pole is processed, and then directly be recorded as nc program according to the program format of ISO code.
