Utility model content
The purpose of this utility model is to provide a kind of internal thread tapping machine, solves existing device structure complicated, long processing time during machining internal thread, the problem that working (machining) efficiency is low.
The technical scheme that the utility model adopts comprises V belt translation, motor driven belts drive motion, the large belt shaft of V belt translation is connected with camshaft by electromagnetic clutch, cam being rotatable be hinged in frame, sector gear afterbody is connected with cam activation, composition higher pair, rotatably be hinged in frame in the middle part of sector gear, when cam rotates, can drive sector gear with in the middle part of sector gear with frame hinged place for axle does oscillating motion, the tooth of the head gear of sector gear engages with the tooth of the tooth bar of band ball nut, when sector gear clockwise oscillation, the tooth bar of band ball nut is driven to move down by head gears meshing, tooth bar with ball nut and ball-screw form rolling screw pair, ball-screw is fixedly connected with pinion, pinion engages with gear wheel, screw rod is arranged on gear wheel center by the axle sleeve of gear wheel, gear wheel rotates, screw rod also rotates, screw rod can slide in the axle sleeve of gear wheel, in screw rod and frame, nut forms sliding spiral pair, screw tap is arranged on the lower end of screw rod.
Further, the pitch of described screw tap is identical with the pitch of screw rod.
The beneficial effects of the utility model are that structure is simple, the tapping of internal thread processed disposablely to complete fast, improve working (machining) efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model internal thread tapping machine;
In figure, 1. V belt translation, 2. electromagnetic clutch, 3. cam, 4. sector gear, 5. tooth bar, 6. ball-screw, 7. pinion, 8. gear wheel, 9. screw rod, 10. screw tap, 11. nuts, 12. motors, 13. frames.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The purpose of this utility model is the deficiency being to overcome prior art, and provides a kind of energy disposable rapid processing internal thread, the internal thread tapping machine that efficiency is high.
As shown in Figure 1, motor 12 rotating band transmission 1 is moved, the large belt shaft of V belt translation 1 is connected with cam 3 axle by electromagnetic clutch 2, cam 3 is rotating to be hinged in frame 13, sector gear 4 afterbody is flexibly connected with cam 3, composition higher pair, rotatably be hinged in the middle part of sector gear 4 in frame 13, when cam 3 rotates, can drive sector gear 4 with in the middle part of sector gear 4 with frame 13 hinged place for axle does oscillating motion, the tooth of the head gear of sector gear 4 engages with the tooth of the tooth bar 5 of band ball nut, when sector gear 4 clockwise oscillation, the tooth bar 5 of band ball nut is driven to move down by head gears meshing, tooth bar 5 with ball nut forms rolling screw pair with ball-screw 6, ball-screw 6 is fixedly connected with pinion 7, pinion 7 engages with gear wheel 8, screw rod 9 is arranged on gear wheel 8 center by the axle sleeve of gear wheel 8, gear wheel 8 rotates, screw rod 9 also rotates, screw rod 9 can slide in the axle sleeve of gear wheel 8.The sliding spiral pair that screw rod 9 forms with nut 11 in frame 13.Screw tap 10 is arranged on the lower end of screw rod 9, and the pitch of its plug tap 10 is identical with the pitch of screw rod 9.
Operation principle of the present utility model is: during work, motor 12 rotating band transmission 1 rotary motion, the large belt shaft of V belt translation 1 is connected with cam 3 axle, at cam 3 rise motion stage by electromagnetic clutch 2, make sector gear 4 clockwise oscillation, drive the tooth bar 5 of band ball nut to move downward.In the process that the tooth bar 5 of band ball nut moves downward, ball-screw 6 rotary motion, thus pinion 7 also rotates, gear wheel 8 is driven to rotate by gears meshing, screw rod 9 also rotates, screw rod 9 relative frame under the effect of the nut 11 of frame 13 moves downward simultaneously, makes the screw tap 10 be arranged on screw rod 9 move downward and rotate, namely achieves the tapping of internal thread.In the drawback movement stage of cam 3, sector gear 4 counter-clockwise swing, tooth bar 5 moves upward, ball-screw 6 counter rotational movement, thus pinion 7 also reversely rotates, drive gear wheel 8 to reversely rotate by gears meshing, screw rod 9 also reversely rotates and moves upward with relative frame, and screw tap 10 also moves upward and rotates backward, exit tapping, electromagnetic clutch 2 is separated, thus makes cam 3 stop motion, completes a tapping.
The utility model has the advantage of:
1, owing to have employed effective combination of cam mechanism, sector-shape rack-and-pinion mechanism, rolling screw vice mechanism, gear mechanism and slip screw vice mechanism, the tapping of internal thread processed disposablely to complete fast, improve working (machining) efficiency;
2, compact conformation, friction are little, shock-resistant.
The above is only to better embodiment of the present utility model, not any pro forma restriction is done to the utility model, every any simple modification above embodiment done according to technical spirit of the present utility model, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
