Description
Technical field
The utility model relates to machining technique field, especially relates to chasing bar.
Background technology
In prior art, the screw tap assembling of chasing bar, manually need fix with instrument, dismounting is very inconvenient, also often there will be screw tap and loosens, situation about even dropping, and this not only causes product tapping bad, and impact is normally produced; Also be not suitable for being arranged on automated production equipment simultaneously, carry out operatorless automated production.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, and provide a kind of fast dismounting chasing bar, screw tap easy accessibility, is applicable to being arranged on automated production equipment, carries out operatorless automated production.
For achieving the above object, the utility model adopts following technical scheme:
Fast dismounting chasing bar, includes screw tap and tooth bar, and described tooth bar one end has external screw thread, and the screw thread on this external screw thread and screw tap is same uniform pitch or pitch in proportion; The other end of tooth bar has axial trepanning, and the interior bottom of axial trepanning has the square opening of the pommel insertion of adaptive screw tap; In described axial trepanning, group is provided with fairlead, and there is spring ejection the inner of fairlead, fairlead inwall is provided with radial direction rise receive clamping section; After the pommel of screw tap inserts assembling via fairlead by this, under the ejection of spring, the automatic adduction in clamping section of fairlead clamps screw tap, reaches screw tap fast-assembling; Otherwise push back fairlead and then reach screw tap quick detach person.
The clamping section of described fairlead is ball, is embedded in the radial taper hole of fairlead, and the conical surface contact that outer convex surface and axial trepanning inwall construct, interior convex surface is the convex inside to fairlead then.
The external screw thread of described tooth bar is threaded a nut, and nut designs for stock, and one end is provided with the external screw thread that internal thread connects tooth bar, and the other end is provided with inner sliding sleeve socket tooth bar; Nut periphery is provided with mounting ears.
Be compared with the prior art, the utility model has following beneficial effect:
1, the external screw thread on tooth bar and the screw thread on screw tap are same uniform pitch or pitch in proportion, and thus tapping feeding is stablized, and stress equalization promotes Tapping Quality, reduces fraction defective, also the service life of effective extension fixture.
2, dismounting screw tap is without the need to instrument, and compressing fairlead forces spring-compressed, the clamping section of fairlead is unclamped and obtains gap for screw tap assembling, the pommel of screw tap is then via after fairlead insertion assembling, under the ejection of spring, the automatic adduction in clamping section of fairlead clamps screw tap, reaches screw tap fast-assembling; Otherwise push back fairlead and then reach screw tap quick detach person.Screw tap easy accessibility, be applicable to being arranged on automated production equipment, and more than one to less than 500 can be installed on automated production equipment simultaneously, so that the processing in a hundreds of tooth hole can be completed within the time of attacking a tooth, reach operatorless automated production, General Promotion production capacity, for user saves labour cost and time.
accompanying drawing illustrates:
Accompanying drawing 1 is the utility model preferred embodiment structural representation;
Accompanying drawing 2 is tooth bar and the fairlead combining structure schematic diagram of Fig. 1 embodiment.
detailed description of the invention:
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
Consult shown in Fig. 1,2, be preferred embodiment schematic diagram of the present utility model, the utility model, about fast dismounting chasing bar, includes screw tap 1 and tooth bar 2, described tooth bar 2 one end has external screw thread 21, and this external screw thread 21 and the screw thread on screw tap 1 are same uniform pitch or pitch in proportion; The other end of tooth bar 2 has axial trepanning 22, and the interior bottom of axial trepanning 22 has the square opening 221 of pommel 11 insertion of adaptive screw tap 1; In described axial trepanning 22, group is provided with fairlead 3, and there is spring 4 ejection the inner of fairlead 3, fairlead 3 inwall is provided with radial direction rise receive clamping section 31; After the pommel 11 of screw tap 1 inserts assembling via fairlead 3 by this, under the ejection of spring 4, the automatic adduction in clamping section 31 of fairlead 3 clamps screw tap 1, reaches screw tap 1 fast-assembling; Otherwise push back fairlead 3 and reach screw tap 1 quick detach person.
Shown in Fig. 1,2, in the present embodiment, the clamping section 31 of described fairlead 3 is ball, is embedded in the radial taper hole 32 of fairlead 3, and outer convex surface contacts with the taper seat 222 that axial trepanning 22 inwall constructs, and interior convex surface is the convex inside to fairlead 3 then.During work, fairlead 3 drives ball to move, and utilizes arbitrfary point on taper seat to obtain auto lock power, thus clamps screw tap 1.The external screw thread 21 of described tooth bar 2 is threaded a nut 5, and nut 5 designs for stock, and one end is provided with the external screw thread 21 that internal thread connects tooth bar 2, and the other end is provided with inner sliding sleeve 51 and is socketed tooth bar 2; Nut 5 periphery is provided with mounting ears 52, and this structure is simple, and make easily, cost is low, installs and uses also easy.Nut 5 does stock design, increase the guide effect to tooth bar 2, inner sliding sleeve 51 contributes to promoting axiality, meets tooth bar 2 when rotating, and also guarantees rectilinear movement, thus contribute to promoting Tapping Quality, reduce fraction defective, external screw thread on tooth bar 2 21 and the screw thread on screw tap 1 are same uniform pitch or pitch in proportion, and thus tapping feeding is stablized, stress equalization, the also service life of effective extension fixture.
The utility model dismounting screw tap 1 is without the need to instrument, only spring 4 need be forced to compress by compressing fairlead 3, make the clamping section 31 of fairlead unclamp acquisition gap to assemble for screw tap 1, after the pommel 11 of screw tap inserts assembling via fairlead 3 immediately, the pommel 11 of screw tap and square opening 221 grafting of the interior bottom of axial trepanning 22, acquisition is rotationally connected, and realizes tooth bar 2 and rotates and drive screw tap 1 to work.After screw tap 1 loads, decontrol fairlead 3, then, under the ejection of spring 4, the automatic adduction in clamping section 31 of fairlead clamps screw tap 1, reaches screw tap fast-assembling, the lasting ejection of spring 4, makes screw tap 1 stable by folder, lasting, not easily gets loose.Otherwise, when dismantle screw tap 1, push back fairlead 3, unclamp clamping section 31, screw tap quick detach person can be reached.Whole disassembly process is simple, convenient, be applicable to being arranged on automated production equipment, and more than one to less than 500 can be installed on automated production equipment simultaneously, so that the processing in a hundreds of tooth hole can be completed within the time of attacking a tooth, reach operatorless automated production, General Promotion production capacity, for user saves labour cost and time.
Certainly; more than in conjunction with embodiment, the utility model is elaborated; only for technical conceive of the present utility model and feature are described; its object is to allow person skilled in the art understand content of the present utility model and to be implemented; therefore; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
