Description
Technical field
The present invention relates to a kind of tiller dust cover processing fraising chuck.
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 dust cover; in order to avoid dust enters into engine or the transmission system of tiller; dust cover needs thread mill drilling; so that by screw fastening on tiller; but reaming tool of the prior art cutter when reaming to dust cover often can be lost because cutting force increases suddenly, and this have impact on production efficiency greatly.
Summary of the invention
The invention is intended to provide a kind of tiller dust cover processing fraising chuck, to enhance productivity.
Tiller dust cover processing fraising chuck in this programme, comprise the taper shank set gradually of turning left from the right side vertically, first screw, first spring, conehead, nut, first steel ball and drive sleeve, taper shank left end is provided with tapering, taper shank left end is provided with the first centre bore, first screw is connected in the first centre bore, centre bore left end is slidably connected conehead, the first spring is provided with between conehead and the first screw, drive sleeve right-hand member is enclosed within taper shank left end, taper shank left end is circumferentially with the first chamber of accommodation first steel ball, the groove of accommodation first steel ball is provided with in drive sleeve right-hand member endoporus, nut right-hand member is fixed on taper shank, nut left end is threaded in drive sleeve right-hand member, cutter is fixed on drive sleeve left end.
Taper shank is contained on machine tool chief axis, and main shaft overlaps transmitting torque, rotary screw by 3 steel balls, nut, shipowners, and change spring to the pressure of conehead, namely changeable steel ball overlaps the size of the frictional force on inwall between three grooves to shipowner, i.e. the size of driving torque.When the cutting force of cutter is excessive suddenly, during the moment of friction produced more than the first spring spring force, between steel ball and drive sleeve, just produce skidding, thus protection cutter is avoided losing.
This apparatus structure is simple, and cutter can be avoided to lose because cutting force increases suddenly, safe and reliable.
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, also comprise the second spring, the second steel ball, clutch cover and jump ring, drive sleeve left end is provided with installing hole, installing hole sidewall is provided with the chute slided for the second steel ball, chute passes in installing hole, is connected in the middle part of drive sleeve with clutch cover right-hand member by the second spring, and in the middle part of clutch cover, endoporus is provided with the boss of locking second steel ball, fastening by jump ring between clutch cover left end and drive sleeve, fixedly secure cutter in installing hole.
Further, also comprise Quick-mounting clamp head body, the second screw, Quick-mounting clamp head body is fixed in installing hole, can pass through the second screw fastening between Quick-mounting clamp head body and cutter, and each only needs are by unclamping the second screw and removable cutting tool, convenient and swift.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
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: taper shank 1, first screw 2, first spring 3, conehead 4, nut 5, first steel ball 6, drive sleeve 7, second spring 8, second steel ball 9, clutch cover 10, jump ring 11, Quick-mounting clamp head body 12, second screw 13.
Embodiment is substantially as shown in Figure 1: tiller dust cover processing fraising chuck comprises taper shank 1, first screw 2, first spring 3, conehead 4, nut 5, first steel ball 6 and the drive sleeve 7 of turning left from the right side vertically and setting gradually, taper shank left end is provided with tapering, the tapering 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, taper shank left end is provided with the first centre bore, first screw is connected in the first centre bore, centre bore left end is slidably connected conehead, the first spring is provided with between conehead and the first screw, drive sleeve right-hand member is enclosed within taper shank left end, taper shank left end is circumferentially with the first chamber of accommodation first steel ball, the groove of accommodation first steel ball is provided with in drive sleeve right-hand member endoporus, nut right-hand member is fixed on taper shank, nut left end is threaded in drive sleeve right-hand member, cutter is fixed on drive sleeve left end, also comprise the second spring 8, second steel ball 9, clutch cover 10 and jump ring 11, drive sleeve left end is provided with installing hole, installing hole sidewall is provided with the chute slided for the second steel ball, chute passes in installing hole, be connected by the second spring with clutch cover right-hand member in the middle part of drive sleeve, in the middle part of clutch cover, endoporus is provided with the boss of locking second steel ball, fastening by jump ring between clutch cover left end and drive sleeve, fixedly secure cutter in installing hole, also comprise Quick-mounting clamp head body 12, second screw 13, Quick-mounting clamp head body is fixed in installing hole, second screw fastening can be passed through between Quick-mounting clamp head body and cutter, each only needs are by unclamping the second screw and removable cutting tool, convenient and swift.
Taper shank is contained on machine tool chief axis, and main shaft overlaps transmitting torque, rotary screw by 3 steel balls, nut, shipowners, and change spring to the pressure of conehead, namely changeable steel ball overlaps the size of the frictional force on inwall between three grooves to shipowner, i.e. the size of driving torque.When the cutting force of cutter is excessive suddenly, during the moment of friction produced more than the first spring spring force, between steel ball and drive sleeve, just produce skidding, thus protection cutter is avoided losing.
This apparatus structure is simple, and cutter can be avoided to lose because cutting force increases suddenly, safe and reliable.
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.
