Abstract
The invention discloses a positive and negative rotation tap chuck, and relates to the field of car assembling. The positive and negative rotation tap chuck comprises a transmission mechanism and a positioning mechanism, the transmission mechanism comprises a taper handle, transition gears and a chuck body, a driving gear is fixed to one end of the taper handle through a positioning pin, the positioning pin extends to the end of the taper handle, the tail of the chuck body is sleeved with a driven gear in a non-contact mode, a driving pin is arranged on the driven gear to extend to the end face, a square key is arranged at the tail of the chuck in the radial direction and extends to the circumferential face of the chuck body, the taper handle and the chick body are coaxial, the square key is located between the taper handle and the chuck body, the driving gear is in gear fit with the driven gear through the two transition gears, a positioning mechanism comprises a tap box, the transmission mechanism is located inside the tap box, the taper handle and the chuck head extend to the exterior of the tap box, positive-phase backward tapping is achieved at the same time, the structure is simple, operation is easy, and large torque can be borne.
Description
Technical field
The present invention relates to assembling field, be specifically related to a kind of rotating tap chuck.
Background technology
Automobile is by the organic assembling body of each parts, therefore last procedure of auto-producing must be assembling, the each parts of no person cannot be combined and mutually coordinate and play its due function, and so-called assembling refers to various parts or assembly to connect by the technology specified and quality requirement the production process being combined into complete product.Relate to a procedure in production process: tapping, tapping is used for the internal thread of process component, and its instrument is screw tap.
In automobile assembling process, not only to rotate forward and carry out tapping, if tapping is hampered, easily cause tapper main shaft frequently to reverse, therefore, need reverse tapping simultaneously, at present to solution many employings friction-type reversion tapping of reversion tapping, utilize friction tapping must maintain larger axial compressive force, usually by manually providing, make the moment of torsion needed for transmission tapping be restricted first, second operation effort in the overall process of tapping, the wearing and tearing of device are also larger.
Summary of the invention
The invention provides a kind of rotating tap chuck, to realize tapping antithesis simultaneously, structure is simple, is easy to operation, can bears moment of torsion large.
This programme is as follows: rotating tap chuck, comprise transmission mechanism and detent mechanism, transmission mechanism comprises taper shank, excessive gear and chuck, taper shank one end is fixed with driven wheel by alignment pin, alignment pin extends to taper shank end, chuck afterbody is set with driven gear, driven gear is provided with drive pin and extends to end face, chuck afterbody radial direction is provided with square button, described square button extends on chuck periphery, described taper shank is coaxial with chuck, square button is positioned between taper shank and chuck, driven wheel and driven gear are connected by two transition gear gears, detent mechanism comprises cone box, it is inner that transmission mechanism is positioned at cone box, it is outside that taper shank and chuck extend to cone box.
This programme operation principle is as follows: when taper shank rotates clockwise and presses down tapping, chuck screw tap is pushed up upwards together, square button is stuck between alignment pin, and taper shank is rotated forward, after having attacked silk by alignment pin, square button and colleting movable wire cone, taper shank upwards lifts, square button and alignment pin depart from, and are stuck between drive pin downwards, and now machine tool chief axis drives chuck to rotate backward by taper shank, driven wheel, transition gear and driven gear, accordingly, the operation of forward and reverse tapping is completed.Structure of the present invention is simple, can bear moment of torsion large.
Further, taper shank stationary drive gear one end is provided with axial circular hole, and chuck afterbody extends in axial circular hole, and axial circular hole can play the effect of positioning and guiding to chuck, make transmission more stable.
Further, alignment pin has two at least, and drive pin has two at least, and taper shank is in chuck transmission process, and the increase of alignment pin and drive pin, can make transmission safety and stability more.
Further, cone box sidewall is provided with handle in taper shank radial direction, facilitates in the course of work, fixture, more stable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: driven wheel 1, taper shank 2, alignment pin 3, driven gear 4, drive pin 5, chuck 6, square button 7, transition gear 8, handle 9, cone box 10, directional hole 11.
Embodiment is substantially as shown in Figure 1: transmission mechanism comprises taper shank 2, excessive gear and chuck 6, taper shank 2 one end is fixed with driven wheel 1 by alignment pin 3, alignment pin 3 extends to taper shank 2 end, chuck 6 afterbody is set with driven gear 4, driven gear 4 is provided with drive pin 5 and extends to end face, chuck 6 afterbody radial direction is provided with square button 7, square button 7 extends on chuck 6 periphery, taper shank 2 is coaxial with chuck 6, square button 7 is positioned between taper shank 2 and chuck 6, taper shank 2 stationary drive gear 1 one end is provided with axial circular hole, chuck 6 afterbody extends in axial circular hole, guiding can be positioned to chuck 6.
As shown in Figure 2, driven wheel 1 and driven gear 4 are connected by two transition gear 8 gears, detent mechanism comprises cone box 10, it is inner that transmission mechanism is positioned at cone box 10, it is outside that taper shank 2 and chuck 6 extend to cone box 10, cone box 10 sidewall is provided with handle 9 in taper shank 9 radial direction, convenient hand steered device at work.In enforcement, alignment pin 3 has two at least, and described drive pin 5 has two at least, and handle is in chuck transmission process, and the increase of alignment pin 3 and drive pin 5, can make transmission safety and stability more.
When taper shank 2 rotates clockwise and presses down tapping, chuck 6 is pushed up upwards together with screw tap, square button 7 is stuck between alignment pin 3, taper shank 2 drives screw tap to rotate forward by alignment pin 3, square button 7 and chuck 6, after having attacked silk, taper shank 2 has upwards lifted, and square button 7 and alignment pin 3 depart from, be stuck between drive pin 5 downwards, drive chuck 6 to rotate backward by taper shank 2, driven wheel 1, transition gear 8 and driven gear 4.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
