Description
Technical field
The utility model relates to a kind of tiller tube kind part tap holder.
Background technology
Tiller with small diesel engine or gasoline engine for power, the features such as have lightweight, volume is little, and structure is simple.Tiller is widely used in the nonirrigated farmland, paddy field, orchard etc. on Plain, mountain area, hills.Mix corresponding facility can carry out drawing water, generate electricity, spray the operation such as medicine, spray, also can draw towed vehicle and carry out short-distance transport, tiller freely can be exercised in field, user-friendly and deposit, eliminating the worry that large-scale farm machinery cannot enter mountain area field, is that vast farmers consumer substitutes the cultivated optimal selection of ox.
Tiller is provided with tube kind part; so that connected row travelling wheel and power output shaft; thread mill drilling is needed in tube kind part; to connect by screw fastening on power output shaft; but tapping tool of the prior art screw tap in tube kind part tapping often can be lost because cutting force increases suddenly, and this have impact on production efficiency greatly.
Utility model content
The utility model is intended to provide a kind of tiller tube kind part tap holder, to enhance productivity.
Tiller tube kind part tap holder in this programme, comprise the taper shank set gradually of turning left from the right side vertically, right friction plate, left friction plate, power transmission shaft, nut, screw tap holder, tapered sleeve and steel ball, taper shank right-hand member is with tapering, power transmission shaft outer rim cover has thread bush, thread bush outer rim is provided with external screw thread, taper shank left end is provided with groove, groove is threaded on thread bush, power transmission shaft left end is provided with boss, right friction plate is connected with between boss right side and groove floor, left friction plate is connected with between boss left side and thread bush, nut is connected to thread bush outer rim and offsets with groove end face, screw tap holder right-hand member is enclosed within power transmission shaft right-hand member and is connected with transmission pivot pin, screw tap holder left end is provided with installing hole, installing hole sidewall is provided with the chute slided for steel ball, chute passes in installing hole, be provided with in the middle part of screw tap holder and be threaded with tapered sleeve right-hand member, the internal taper hole of tapered sleeve left end extends on steel ball.
During work, taper shank is arranged on machine tool chief axis, when taper shank rotates, makes drive axis by right friction plate, left friction plate, then drives screw tap holder and screw tap to rotate tapping by power transmission shaft.Unclamp nut, taper shank can be regulated the size of the frictional force of power transmission shaft, when screw tap cutting force is too large, produces and skid between power transmission shaft and right friction plate, left friction plate, protection screw tap is in order to avoid lose because cutting force increases suddenly.Tapered sleeve clamps screw tap shank by steel ball; This programme structure is simple, and convenient and swift, processing ease, can protect screw tap in order to avoid lose because cutting force increases suddenly, substantially increase production efficiency.
Further, the tapering of taper shank is No. 3 Morse's tapers, and Morse's taper is the international standard of a tapering, for stationary fit accurately to locate.Because tapering is very little, utilize the principle of frictional force, certain moment of torsion can be transmitted, again because be taper fit, so can dismantle easily.In the certain limit of same tapering, workpiece is free to dismounting, operationally can not have influence on result of use again simultaneously.
Further, thread bush left end is the conical surface of right-to-left size reduction vertically, nut of can easily backing off.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: taper shank 1, right friction plate 2, left friction plate 3, power transmission shaft 4, nut 5, tapered sleeve 6, steel ball 7, the conical surface 8.
Embodiment is substantially as shown in Figure 1: tiller tube kind part tap holder comprises taper shank 1, right friction plate 2, left friction plate 3, power transmission shaft 4, nut 5, screw tap holder, tapered sleeve 6 and the steel ball 7 of turning left from the right side vertically and setting gradually, taper shank right-hand member is with tapering, the conical surface of taper shank is No. 3 Morse's tapers, Morse's taper is the international standard of a tapering, for stationary fit accurately to locate.Because tapering is very little, utilize the principle of frictional force, certain moment of torsion can be transmitted, again because be taper fit, so can dismantle easily.In the certain limit of same tapering, workpiece is free to dismounting, operationally result of use can not be had influence on again simultaneously, power transmission shaft outer rim cover has thread bush, thread bush outer rim is provided with external screw thread, taper shank left end is provided with groove, groove is threaded on thread bush, power transmission shaft left end is provided with boss, right friction plate is connected with between boss right side and groove floor, left friction plate is connected with between boss left side and thread bush, nut is connected to thread bush outer rim and offsets with groove end face, thread bush left end is the conical surface of right-to-left size reduction vertically, can easily to back off nut, screw tap holder right-hand member is enclosed within power transmission shaft right-hand member and is connected with transmission pivot pin, screw tap holder left end is provided with installing hole, installing hole sidewall is provided with the chute slided for steel ball, chute passes in installing hole, be provided with in the middle part of screw tap holder and be threaded with tapered sleeve right-hand member, the internal taper hole of tapered sleeve left end extends on steel ball.
During work, taper shank is arranged on machine tool chief axis, when taper shank rotates, makes drive axis by right friction plate, left friction plate, then drives screw tap holder and screw tap to rotate tapping by power transmission shaft.Unclamp nut, taper shank can be regulated the size of the frictional force of power transmission shaft, when screw tap cutting force is too large, produces and skid between power transmission shaft and right friction plate, left friction plate, protection screw tap is in order to avoid lose because cutting force increases suddenly.Tapered sleeve clamps screw tap shank by steel ball; This programme structure is simple, and convenient and swift, processing ease, can protect screw tap in order to avoid lose because cutting force increases suddenly, substantially increase production efficiency.
Above-described is only embodiment of the present utility model, 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 the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.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.
