Description of drawings
Do further detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention:
Structural representation when Fig. 1 is tapping, the feeding of drilling screw all-in-one.
Structural representation when Fig. 2 is tapping, drilling screw all-in-one withdrawing.
The specific embodiment
Shown in Fig. 1 or 2, a kind of tapping, drilling screw all-in-one are provided with little soldered tooth 2 in the inside of housing 1; Its endoporus is provided with turning cylinder 3; Turning cylinder 3 flexibly connects one through key 4 and takes turns glue 5, takes turns glue 5 and is interference fit with turning cylinder 3, takes turns the upper and lower taper seat and the following taper seat of being respectively equipped with of the excircle of glue 5; Close in the bottom surface of taking turns glue 5 and brief summary and to be provided with spring 6 between the tooth 2, the below of little soldered tooth 2 is an external gear; On the upper surface of housing 1 cavity, be provided with 1～4 pinion 7,7 one-tenth circumferential arrangement of pinion, the internal tooth engagement of each pinion 7 and big soldered tooth 8, simultaneously pinion 7 also with the external gear engagement of the below of little soldered tooth 2; The inwall of big soldered tooth 8 is provided with a taper seat, and the angle of this taper seat is identical with the last taper seat angle of taking turns glue 5, and the inwall of little soldered tooth 2 also is provided with a taper seat, and the angle of this taper seat is identical with the following taper seat angle of taking turns glue 5; Be provided with end cap 9 in the upper end of housing 1; Be provided with clutch shaft bearing 10 in the end cap 9, the below of clutch shaft bearing 10 is provided with bearing cap 17, clutch shaft bearing 10 internal diameters and firm bar 11 interference fit; The lower end of firm bar 11 is positioned at the internal diameter of end cap 9, and is threaded with big soldered tooth 8; Below housing 1, be provided with second bearing 12 in the endoporus,, turning cylinder 3 cooperates with the internal diameter of second bearing 12.
Described firm bar 11 outer walls are provided with the internal thread 13 that communicates with internal diameter, are provided with push rod 14 in it.
Also be connected with holding clamp 15 on the described end cap 9.
The main shaft 16 of small drilling machine is inserted in the endoporus of firm bar 11 of this tapping, its upper end of drilling screw all-in-one; And with push rod 14 main shaft is held out against, the lower end of its turning cylinder 3 can connect screw tap, is used for machining internal thread; Install and fix the connector and the circular die of circular die in the lower end of turning cylinder 3; Can threading, when small drilling machine main shaft 16 rotates, can realize that tapping, drilling screw are integrated.
Its dynamic course of work is following:
As shown in Figure 1, when main shaft 16 rotated, the holding clamp 15 that connects on the housing 1 was fixed on the lathe bed of small drilling machine, so housing 1 does not rotate; Firm bar 11 is threaded with big soldered tooth 8, and main shaft 16 promptly rotates big soldered tooth 8 through firm bar 11; Because turning cylinder 3 is the feeding state; Turning cylinder 3 has the power of a reaction force that makes progress and spring 6 all the time; The last taper seat of taking turns glue 5 is combined closely with the taper seat of big soldered tooth 8, produce very big frictional force, make and take turns glue 5 rotations; Drive turning cylinder 3 through key 4 simultaneously and rotate, thereby realize turning to identical feeding with main shaft 16.
As shown in Figure 2, when the feeding end, screw tap or circular die need from the screw thread of processing, withdraw from; When upwards pulling up, turning cylinder 3 promptly has a downward power, makes turning cylinder 3 produce downward displacement; At this moment, take turns the following taper seat of glue 5 and the taper seat of little soldered tooth 2 and combine closely, produce very big frictional force; Make and take turns glue 5 rotations, because big soldered tooth 8 drives pinions 7, pinion 7 drives little soldered tooth 2 again; Change the direction of little soldered tooth 2 through the two-stage transmission, make little soldered tooth 2 make turning cylinder 3 counter-rotatings, thereby realize withdrawing from of screw tap or circular die through taking turns glue 5.
