Description
Technical field
The utility model relates to a kind of tiller adapter sleeve processing floating reamer 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 adapter sleeve, to connect, gear etc. is fixed in rotating shaft, connecting hole on adapter sleeve needs to carry out fraising processing, and (fraising is one of the method for fine finishing in hole, apply very wide aborning, for less hole, for internal grinding and right boring, fraising is a kind of comparatively economical and practical processing method, fraising is that reamer excises trace meter layer from workpiece hole wall, to improve the method for its dimensional accuracy and hole surface quality), but reamer chuck of the prior art is fixed, and centring property is poor, fraising weak effect.
Utility model content
The utility model is intended to provide a kind of tiller adapter sleeve processing floating reamer chuck, to improve fraising effect.
Floating reamer chuck is used in tiller adapter sleeve processing in this programme, comprise the reamer set gradually from left to right vertically, chuck, screw, spring, collet body and taper shank, reamer right-hand member by screw fastening on chuck, screw comprises screwing, lower screw, taper shank left end is provided with threaded portion, taper shank right-hand member is with tapering, taper shank right-hand member size reduces from left to right gradually, collet body right-hand member is threaded on taper shank, chuck left end is provided with bar-shaped trough, lower bar-shaped trough, collet body is stretched out through upper bar-shaped trough in screwing one end, lower screw stretches out collet body through lower bar-shaped trough, reamer right side is provided with centre bore, taper shank left side is provided with top, spring connecting taper shank left side and chuck.
During work, reamer is by screw fastening on chuck, and taper shank is contained on machine tool chief axis, cut with scissors during fraising to move after pressurized on the centre bore top of its afterbody taper shank leading portion top till, taper shank drives reamer to carry out ream.Reamer has one to float freely in collet body, is convenient to centering.This programme structure is simple, convenient and swift, facilitates reamer automatic centering, substantially increases fraising effect.
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 adjusting nut being connected to threaded portion, adjusting nut is against on collet body right side, plays spacing and auxiliary fixing effect, can also prevent collet body from loosening.
Further, described top be that bulb is top, facilitate centering, and the top bearing capacity of bulb is strong, makes structure more stable.
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: reamer 1, chuck 2, screw 3, spring 4, collet body 5, adjusting nut 6, taper shank 7.
Embodiment is substantially as shown in Figure 1: tiller adapter sleeve processing floating reamer chuck comprises the reamer 1 set gradually from left to right vertically, chuck 2, screw 3, spring 4, collet body 5 and taper shank 7, reamer right-hand member by screw fastening on chuck, screw comprises screwing, lower screw, taper shank left end is provided with threaded portion, also comprise the adjusting nut 6 being connected to threaded portion, adjusting nut is against on collet body right side, play spacing and auxiliary fixing effect, can also prevent collet body from loosening, taper shank right-hand member is 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 can not have influence on result of use again simultaneously.Taper shank right-hand member size reduces from left to right gradually, collet body right-hand member is threaded on taper shank, and chuck left end is provided with bar-shaped trough, lower bar-shaped trough, and collet body is stretched out through upper bar-shaped trough in screwing one end, lower screw stretches out collet body through lower bar-shaped trough, reamer right side is provided with centre bore, and taper shank left side is provided with top, described top be that bulb is top, facilitate centering, and the top bearing capacity of bulb is strong, makes structure more stable, spring connecting taper shank left side and chuck.
During work, reamer is by screw fastening on chuck, and taper shank is contained on machine tool chief axis, cut with scissors during fraising to move after pressurized on the centre bore top of its afterbody taper shank leading portion top till, taper shank drives reamer to carry out ream.Reamer has one to float freely in collet body, is convenient to centering.This programme structure is simple, convenient and swift, facilitates reamer automatic centering, substantially increases fraising effect.
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.
