Abstract
The utility model discloses a hand-operated tapping machine. According to the hand-operated tapping machine, torque is input through a hand-operated wheel, the torque applied to the hand-operated wheel by human hands is amplified and transferred to a working screw tap through a speed reducing mechanism composed of a driving bevel gear and a driven bevel gear, and more labor is saved in a manual tapping process. The hand-operated tapping machine comprises a multifunctional T-shaped groove workbench, a working frame and a feeding mechanism, wherein the working frame can be lifted vertically, and the feeding mechanism is composed of a feeding thrust threaded rod and a feeding nut; a forced spiral feeding mode is adopted for the hand-operated tapping machine in the tapping process, and the problem that thread stripping occurs in the tapping process is solved. Meanwhile, because the feeding mode is similar to a numerical control tapping equipment mode, the working screw tap can be a hand screw tap or a machine screw tap and can even be an extruded screw tap or an inner bore tapping knife. The hand-operated tapping machine has the advantages of being simple in structure, convenient to operate, high in machining precision, wide in application range, good in adaptability, high in practicality and the like.

Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of hand-rail type tapping machine is provided.
For achieving the above object, the utility model adopts following technical proposals:
A kind of hand-rail type tapping machine, vertical direction comprises successively: adjusting handle, rail plate, falsework slide block, dust cover, falsework and workbench, described adjusting handle is connected with leading screw and is fixed on rail plate upper end, described falsework slide block is installed on rail plate, described dust cover is arranged on falsework upper surface, described falsework slip front is provided with rail plate lock valve, the upper end of feeding thrust threaded rod is connected and fixed by feeding nut, feeding nut is fixed on and feeds in nut holder front end draw-in groove, feed nut holder and be bolted on falsework slip front, described feeding thrust threaded rod lower end promotes to overlap and be connected on engaging sleeve with feeding, feeding promotion engaging sleeve is trapped and is fixed with keyway push rod upper end, upper and lower corresponding connection of two covers, tap chuck and screw tap are installed in keyway push rod lower end, and the bar top cover of keyway push rod has spring, and the bar bottom of keyway push rod is through rotating mounting centre bore, rotate mounting upper surface and be connected by dynamic bevel gear, rotate mounting lower end and be arranged on falsework by bearing, drive bevel gear is connected with bearing and is fixed on workbench by bearing fixed cap, afterbody in drive bevel gear is provided with hand-operated wheel, dust cover covers by dynamic bevel gear installment work frame, and falsework below is provided with workbench.On described table surface, be provided with T-shaped groove.
The beneficial effects of the utility model are: 1. the falsework entirety of this hand-rail type tapping machine can be along rail plate vertical lift, can arbitrarily regulate as required the distance of falsework and workbench, and on falsework slide block, be furnished with rail plate lock valve, after locking, can guarantee this device falsework stable in the time of normal work; 2. on falsework, fix feeding scale, can accurately indicate the feeding distance of cutter, can accurately control screw thread working depth.3. be installed into thrust threaded rod and feed nut, solved easy stripped thread and the poor problem of crudy in manual tapping process.4. the workbench of this hand-rail type tapping machine adopts T-shaped groove planar structure, can meet the fixing various multi-form technological equipments of user.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structure side view;
Fig. 3 is the utility model structure top view;
Structural representation when Fig. 4 is the utility model motion;
Wherein 1. falsework height adjusting handles, 2. rail plate, 3, feeding scale, 4. feeding thrust threaded rod, 5. feed nut fixed mount, 6. feed nut, 7. feeding promotes to overlap on engaging sleeve, and 8. feeding promotion engaging sleeve is trapped, 9. spring, 10. keyway push rod, 11. by dynamic bevel gear, 12. rotate mounting, 13. falseworks, 14. bearings, 15. rail plate lock valves, 16. falsework slide blocks, 17. dust covers, 18. drive bevel gear, 19. bearing fixed caps, 20. hand-operated wheels, 21. tap chucks, 22 screw taps, 23. workbench.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As Fig. 1, 2, shown in 3 and 4, a kind of hand-rail type tapping machine, first the feed nut 6 of selecting the feeding thrust threaded rod 4 identical with processing screw tap pitch when use and match is arranged on feed nut fixed mount 5, part to be processed is placed on workbench 23, unclamp rail plate lock valve 15, rotation adjusting handle 1, falsework slide block 16 is moved on rail plate 2, after falsework 13 positions adjustment are suitable, by rail plate lock valve 15, falsework 13 is fixed, hand-operated wheel 20 turns clockwise, now drive bevel gear 18 is by rotating moment of torsion that hand-operated wheel 20 is inputted and amplify with being engaged by dynamic bevel gear 11, and drive rotation mounting 12 to rotate on falsework 13 by bearing 14, also driven keyway push rod 10 simultaneously, tap chuck 21, screw tap 22 rotates together.When inferior feeding promote engaging sleeve trap 8 drive feedings promote to overlap on engaging sleeves 7 and feeding thrust threaded rod 4 rotate, because feed nut 6 maintains static, so will force feeding thrust threaded rod 4 to be rotated down propelling, in progradation, promote engaging sleeve and trap 8 by Compress Spring 9, screw tap 22 enters duty, in process, necessarily guarantee that processing parts can not move, the feeding reading of observing feeding scale 3 arrives after the working depth of predetermined screw thread, be rotated counterclockwise hand-operated wheel 20, feeding thrust threaded rod 4 is upwards return, spring 9 stretches and drives keyway push rod 10 rollbacks simultaneously, when screw tap 22 departs from after processing parts completely, process finishing.Dust cover 17 plays the effect of protective cone gear, and bearing fixed cap 19 plays the effect of fixing drive bevel gear 18.
By reference to the accompanying drawings the specific embodiment of the present utility model is described although above-mentioned; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
