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, described upper end cover 17 and bottom end cover 2 are installed in the top and bottom of housing 8 respectively, described 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 by the upper bearing (metal) 6 that is installed on the top chock 9 that described rotating shaft 1 is installed in housing 8, described rotating shaft 1 passes and in the termination that it passes cutter is installed from bottom end cover 2, described p-m rotor assembly 5 be installed on the described rotating shaft 1 and described p-m rotor assembly 5 corresponding with stator module 4, the rear end of described rotating shaft 1 is provided with encoder 7, be provided with the locking nut 3 that moving axially of lower bearing 10 limited between described step 11 and the bottom end cover 2, the upper end of described housing 8 is provided with clamping device, described clamping device comprises holding piece one and the holding piece two with housing 8 upper ends parcel, and described holding piece one and holding piece two are installed in the tapping machine rocking arm 12 that is positioned on the rigid tapping machine Z axle 13 in the mode of interference fit, and described adding held sheet one and holding piece two is provided with installing hole.Be provided with sealing ring between part that described 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; earlier rocking arm 12 left ends heats during assembling; 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, 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 so stabilization of speed is the machining accuracy height.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of technical solutions of the utility model.
