The specific embodiment
A kind of rigid tapping machine as shown in Figure 1 is with the synchronous electric main shaft of AC permanent-magnet; Comprise housing 8, stator module 4, p-m rotor assembly 5, rotating shaft 1, upper end cover 17, bottom end cover 2, top chock 9 and step 11; Said upper end cover 17 and bottom end cover 2 are installed in the top and bottom of housing 8 respectively; Said stator module 4 is installed in housing 8 inwalls; It is inner and be connected with bottom end cover 2 with upper end cover 17 respectively with lower bearing 10 on being installed in step 11 through the upper bearing (metal) 6 that is installed on the top chock 9 that said rotating shaft 1 is installed in housing 8; Said rotating shaft 1 passes and in the termination that it passes cutter is installed from bottom end cover 2; Said p-m rotor assembly 5 be installed on the said rotating shaft 1 and said p-m rotor assembly 5 corresponding with stator module 4, the rear end of said rotating shaft 1 is provided with encoder 7, is provided with the locking nut 3 that moving axially of lower bearing 10 limited between said step 11 and the bottom end cover 2; The upper end of said housing 8 is provided with clamping device; Said clamping device comprises the holding piece one and holding piece two with housing 8 upper ends parcels, and said holding piece one and holding piece two be installed in the tapping machine rocking arm 12 that is positioned on the rigid tapping machine Z axle 13 with the mode of interference fit, and said adding holds sheet one and be provided with installing hole with holding piece two.Be provided with sealing ring between part that said rotating shaft 1 stretches out from bottom end cover 2 and the bottom end cover 2.
When carry out after integral body wraps the synchronous electric main shaft housing of AC permanent-magnet 8 upper ends; rocking arm 12 left end endoporus and clamping device adopt interference fit, and earlier with the heating of rocking arm 12 left ends, the electric main shaft hot jacket that will wrap while hot advances in the rocking arm 12 left end endoporus; stretching screw 14 (threaded) is screwed into installing hole inside; the nut 15 that tightens up with right-hand member is locked in advance during assembling, wait rocking arm 12 recovery normal temperature after, will tighten up nut 15 again and tighten.Like this, the synchronous electric main shaft of AC permanent-magnet is when work, and stability is better, but shock resistance.Have oilhole 16 on the rocking arm 12, when the synchronous electric main shaft of need dismountings AC permanent-magnet, can feed hydraulic oil, under the high pressure effect, the synchronous electric main shaft of AC permanent-magnet can be pulled down from the left end endoporus of rocking arm 12 smoothly.
In theory, during tapping, when the synchronous electric main shaft of AC permanent-magnet turned around, the feeding total amount of rigid tapping machine Z axle 13 should equal the pitch of screw tap.That is:
P＝F/S
The pitch of P-screw tap in the formula, mm
The amount of giving of F-Z axle, mm/min
The S-speed of mainshaft, r/min
Give regularly when the pitch P of workpiece, guarantee that the precision of machining screw is good, uniformity is strong, can set the rotating speed of the synchronous electric main shaft of AC permanent-magnet according to the metering F that send of rigid tapping machine Z axle 13.When at the high speed rigid tapping, the asynchronous electric speed of mainshaft is corresponding asynchronous, and rotary speed unstabilization is fixed, so the precision of machining screw is very low, the synchronous electric main shaft of AC permanent-magnet is under high-speed case, and stabilization of speed is so machining accuracy is high.
The above; It only is preferred embodiment of the present invention; Be not that the present invention is done any restriction, every technical spirit all still belongs in the protection domain of technical scheme of the present invention any simple modification, change and equivalent structure transformation that above embodiment did according to the present invention.
