In order that interior axle can not be rotated relative to sleeve body but sleeve body can moved axially relatively, outside the sleeve body 104 Circle is tightly fixed in the medium pore of rotor core 103, and the back segment coaxial sleeve of the interior axle 105 is located at sleeve body 104 Interior, the interior axle 105 is provided with axially distributed keyway 1052, is also associated with leading between the sleeve body 104 and interior axle 105 To nail 106, one end of the guide pin 106 is fixedly installed on sleeve body 104, the other end width of the guide pin 106 with The width of keyway 1052 matches and is slidably connected in keyway 1052 so that interior axle 105 can not be rotated relative to sleeve body 104 but The relative sleeve body 104 of energy is moved axially.
The connection member for installing screw tap or screw die includes chuck 601 and chuck nut 602, the front end of interior axle 105 Middle part is provided with the internal taper hole for being connected with chuck 601, and the front end periphery of interior axle 105 is provided with for being connected with chuck nut 602 External screw thread.
The operation principle of the utility model is:Before start, shut down adjusting screw 414 and be in compressing shutdown travel switch 415 Position, the end face of frictional disk 408 and bears the elastic force compressing of brake spring 413 close to the front end face of rotation stop disk 409, range line The front end step surface of the rear end outward flange of screw 412 and the rear end face of rear fixed plate 204, the rear end face of rotation stop disk 409 and rear fixation The front end face of plate 204 leaves gap simultaneously, and gap length is any, and regulates the height of stroke limit screw 302.
Electric machine assembly 1 is powered during start, and the sleeve body 104 being fixedly connected with rotor core 103 drives interior axle 105, main spiral shell Bar 201, bearing axle 402, two-way bearing washer 403, the inner ring of two-way bearing 404, unilateral bearing packing ring 405, unilateral bearing 407 Inner ring, bearing axle screw 411, chuck 601, chuck nut 602 and screw tap or screw die synchronously rotate forward.Due to unilateral bearing 407 In energy relative motion state when Internal and external cycle is rotated forward, the rear end face of the frictional disk 408 of the outer ring of unilateral bearing 407 of ining succession is close to only The front end face of rotating disk 409, and bear the elastic force compressing of brake spring 413 and produce frictional force to hinder, so, frictional disk 408 is not Rotation.With interior axle 105, driving disc spacing pressing 401, bearing axle 402, double while the driving screw 201 screwed up through mother nut 202 rotates To bearing washer 403, two-way bearing 404, unilateral bearing packing ring 405, unilateral bearing internal key 406, unilateral bearing 407, frictional disk 408th, before unilateral bearing external key 410, bearing axle screw 411, chuck 601, chuck nut 602 and screw tap or screw die DL synchronization Enter, here it is the transmission mechanism of bolt and nut, the rotor core 103 of electric machine assembly for each revolution, interior axle 105 and driving screw 201 just advance the pitch of a tooth driving screw 201 distance.Acted on by the elastic force of brake spring 413, rotation stop disk 409 and range line screw 412 also with the descending advance of driving screw 201.
When the front end step surface of the rear end outward flange of range line screw 412 encounters the rear end face of rear fixed plate 204, limit of ining succession Rotation stop disk 409 away from screw 412 is obstructed and stops descending advance, and driving screw 201 departs from rotation stop disk 409 with frictional disk 408 Front end face contact continues traveling downwardly advance.
After the screw tap or screw die that interior axle 105 of ining succession is rotationally advancing touch workpiece, tapping pace receives screw tap or plate The pitch control of tooth itself, because the forward travel distance that driving screw 201 is produced relative to mother nut 202 for each revolution is intrinsic , so, interior axle 105 becomes one tooth screw tap of advance to driving screw 201 or the distance of screw die pitch enters working line for each revolution Journey, in the case where the pitch of driving screw 201 is more than screw tap or screw die pitch, often advance a tooth, and interior axle 105 all overcomes pitch to adapt to The elastic force of spring 5 carry out upwards it is axially adjustable come compensate the range difference away from.(it is equal to screw tap or screw die spiral shell in the pitch of driving screw 201 It is synchronous tapping in the case of, changes and retreat problem in the absence of the pace of interior axle 105.)
When adjustable stroke limit screw 302 encounters commutation travel switch 301 on the driving disc spacing pressing 401 of together descending advance When, tapping impulse stroke in place, is inverted by the electric machine assembly 1 of outer electrical equipment control, the spiral shell that screw tap or screw die have been produced along workpiece Line exits workpiece, meanwhile, pitch adapts to synchronous original position interior axle 5 being pushed into relative to driving screw 201 of spring 5.
Similarly, after screw tap or screw die exit workpiece, and the speed advanced by initial idle stroke is retreated.
Encounter the shutdown stroke that is fixed on rotation stop disk 409 when adjusting screw 414 is shut down on the driving disc spacing pressing 401 for together retreating When switching 415, disconnected by the power supply of the electric machine assembly of outer electrical equipment control, but electric machine assembly 1 is also in inertial rotation, driving screw 201 It is inconjunction with unilateral bearing 407 and frictional disk 408 still presses to rotation stop disk 409, forces rotation stop disk 409 to overcome own wt and brake The elastic force of spring 413 can just stop after retreating a segment distance.Due to unilateral bearing 407 reverse directions Internal and external cycle be in can not phase To motion state, it is fixed together equivalent to Internal and external cycle, so, the meeting of frictional disk 408 ined succession with the outer ring of unilateral bearing 407 and main The synchronous rotary of screw rod 201, when the rear end face of frictional disk 408 presses to rotation stop disk 409, the rear end face and rotation stop disk of frictional disk 408 409 front end face produces friction, the inertial rotation of electric machine assembly 1 is quickly stopped, and a work period completes.
By designing the elastic force of brake spring 413 and the length in the stage casing of range line screw 412, it is possible to allow a work period After the completion of rotation stop disk 409 control with the discontiguous position of rear fixed plate 204, that is, return to original state.
Above-mentioned specific embodiment is that the technical solution of the utility model is explained in detail, and the utility model is not Above-described embodiment is only limited only to, every any improvement or replacement according to the utility model principle all should be new in this practicality Within the protection domain of type.
