Abstract
The invention relates to a drilling and tapping machine for pushing the feeding of a motor inner shaft by using a cylinder, relating to drilling machines and tapping machines. A motor main shaft on a machine frame is composed of a shaft sleeve body with an internal spline and an inner shaft with an external spline. The shaft sleeve body and the inner shaft are detachable. A clamping head is installed at the lower end of the inner shaft. A step shaft fixed at the rear end of the inner shaft is used for pressing a return spring on the outer end face of the shaft sleeve body. A steel ball is put on the upper end face of the step shaft in a sleeving manner. A one-way magnetic thin cylinder is fixed on the rear cover of the motor. The piston of the one-way magnetic thin cylinder presses against the steel ball. A damping and limiting mechanism composed of a limiting sleeve, a lower spring base, a locking nut, an upper spring base, a limiting screw and a pre-compression spring is arranged at the upper part of the piston rod in a sleeving manner. The pre-compression spring is installed between the upper and the lower spring bases. A magnetic induction access switch is installed on the outer wall of the one-way magnetic thin cylinder corresponding to the work starting position and the work ending position. With the help of a mechanical or hydraulic damping and adjusting mechanism, cutters can advance in place at high speed during idle stroke and also can automatically decelerate in a working condition stroke by taking the motor shaft as the lifting shaft and taking the one-way magnetic thin cylinder as the lifting power.

Can not install during tapping, during boring, damping limit mechanism will be installed.The concrete running in operating mode of mechanical type damping limit mechanism is as follows:
When being used in boring, first stop collar 9 lower surfaces of damping limit mechanism and the upper surface spacing of one-way tape magnetic thin cylinder 8 are adjusted to idle stroke length.Control method is: as long as after turning the length to axial that is threaded between stop collar 9 and lower spring cup 11, then with locking nut 12 lockings.The upper plane that regulates simultaneously stop screw 14, makes place, final position that work timing position screw 14 goes downwards to encounter lower spring cup 11, play the severity control effect, the more lower magnetic induction switch 17 of regulating on one-way tape magnetic thin cylinder 8 outer walls is positioned at the correspondence position of destination county at the magnetosphere that can sense cylinder piston 7.
Squirrel cage motor 1 energising during start, the sleeve body 3 of ining succession with rotor core 2, the interior axle 4 that drives waterproof cover 16, spline structure, Step Shaft 5, steel ball, return spring 6, with the chuck synchronous rotary.8 air inlets of one-way tape magnetic thin cylinder, cylinder piston 7 is subjected to air pressure to promote to produce axial force by steel ball, Step Shaft 5 passes to interior axle 4, the elastic force that overcomes return spring 6 advances, return spring 6 makes the steel ball that Step Shaft 5 is ined succession head on all the time piston 7, the steel ball rotation, piston 7 does not rotate, both become CONTACT WITH FRICTION, producing idle stroke advances fast, when stop collar 9 along with descending stopped by one-way tape magnetic thin cylinder 8 upper covers after, be subject to the resistance of the piston rod 10 that upper spring seat 13 that pre-pressing spring 15 upwards heads on hauls, the slack-off impulse stroke that enters of speed, and this period of slowing down hole just cutting operating mode trip segment need to be than idle stroke section period at a slow speed.the upper plane of encountering lower spring cup 11 when stop screw 14 is descending, boring puts in place, magnetosphere on piston 7 triggers the lower magnetic induction approach switch 17 of the adjusted good position of cylinder outer wall, the external air reversing valve of lower magnetic induction approach switch 17 makes one-way tape magnetic thin cylinder 8 lose heart immediately, the quick resilience of pre-pressing spring 15, return spring 6 overcomes interior axle 4, Step Shaft 5, steel ball, chuck, piston 7, the weight of piston rod 10 and all parts of damping limit mechanism and axial friction be returning quickly also, when the magnetosphere on piston 7 is got back to the upper magnetic induction approach switch 17 of initial position triggering, power-off is out of service, a boring work period completes.
In fluid pressure type damping limit mechanism operating mode, concrete running is as follows:
When the fluid pressure type damping limit mechanism is used in boring, first regulate hydraulic damper 19 height installation site, make the spacing of its damper rod lower surface and one-way tape magnetic thin cylinder 8 upper surfaces as idle stroke length, then the fixed hydraulic damper 19, advance fast in the idle stroke section when piston rod 10 is descending, after damper rod touched one-way tape magnetic thin cylinder 8 upper surfaces, hydraulic damper 19 worked, and has slowed down the downstream rate of piston rod 10.First regulate stop screw 14 before boring and highly lock behind the installation site, boring procedure is also first idle stroke, then the damping stroke.The termination of damping stroke is withstood one-way tape magnetic thin cylinder 8 upper surfaces by stop screw 14.The control method of magnetic induction switch 17 is consistent with the control method in the mechanical type damping limit mechanism.
As the tapping used time, take off the damping limit mechanism on piston rod 10, circuit switches to another control circuit, adjusting limit method is upper magnetic induction approach switch 17 invariant positions, reaches the tapping degree of depth by the upper-lower position of adjusting lower magnetic induction approach switch 17.
squirrel cage motor 1 energising during start, 8 air inlets of one-way tape magnetic thin cylinder, the in succession screw tap rotation and advancing fast of interior axle 4, after touching workpiece, pace is subjected to rotating speed and the control of screw tap pitch to carry out tapping, when the screw tap tapping degree of depth puts in place, magnetosphere on piston 7 triggers the lower magnetic induction approach switch 17 of the adjusted good position of cylinder outer wall, the external air reversing valve of lower magnetic induction approach switch 17 makes one-way tape magnetic thin cylinder 8 lose heart immediately, external A.C. contactor makes motor power commutation counter-rotating simultaneously, screw tap is retreated by rotating speed and pitch control in workpiece, after screw tap withdraws from workpiece, return spring 6 overcomes interior axle 4, Step Shaft 5, steel ball, chuck, piston 7, the weight of piston rod 10 and all parts of damping limit mechanism and axial friction returning quickly, when the magnetosphere on piston 7 is got back to the upper magnetic induction approach switch 17 of initial position triggering, power-off is out of service, a tapping work period completes.
Damping limit mechanism can be mechanical type, fluid pressure type or produce cylinder thrust difference by stroke contact switch control cylinder valve flow, cause the mode of piston rod 10 velocity variations.
