Description
Technical field
The utility model relates to a kind of tiller dust cover tool for processing.
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, but clamping tool of the prior art often fixes insecure when clamping dust cover or operation is too complicated, and these not only have impact on machining accuracy, and have impact on production efficiency.
Utility model content
The utility model is intended to provide a kind of tiller dust cover tool for processing, to enhance productivity.
Tiller dust cover tool for processing in this programme, comprise axle body, also comprise spline pin, locating piece, expansion set and conical indenter, axle body left end is detachably connected on machine tool chief axis, axle body right-hand member is the first taper surface that diameter rightward reduces gradually, axle body central is provided with slideway, pull bar slides in slideway, pull bar right-hand member stretches out axle body and is connected and fixed conical indenter, conical indenter outer rim is the second taper surface that diameter reduces left gradually, axle first taper surface right-hand member is fixing lug boss, fixing lug boss circumference is connected and fixed multiple locating piece, expansion set one end is the first inner conical surface coordinated with the first taper surface, the expansion set other end is the second inner conical surface coordinated with the second taper surface, expansion set is hollow and is circumferentially with dilatation joint, rubber seal plug is provided with in dilatation joint.
Compared with prior art, the utility model has the advantage of: comprise axle body, also comprise spline pin, locating piece, expansion set and conical indenter, axle body left end is detachably connected on machine tool chief axis, axle body right-hand member is the first taper surface that diameter rightward reduces gradually, axle body central is provided with slideway, pull bar slides in slideway, pull bar right-hand member stretches out axle body and is connected and fixed conical indenter, conical indenter outer rim is the second taper surface that diameter reduces left gradually, axle first taper surface right-hand member is fixing lug boss, fixing lug boss circumference is connected and fixed multiple locating piece, expansion set one end is the first inner conical surface coordinated with the first taper surface, the expansion set other end is the second inner conical surface coordinated with the second taper surface, pull pull bar can realize expansion set two ends swelling simultaneously workpiece, expansion set is hollow and is circumferentially with dilatation joint, dilatation joint is convenient to expansion set and is expanded, rubber seal plug is provided with in dilatation joint, rubber seal plug can prevent iron filings from entering in expansion set, affect expansion set to coordinate with the contact of conical indenter or axle body.
During work, be enclosed within by workpiece on expansion set, inner hole of workpiece and expansion set are located, workpiece intrados is then against on locating piece and locates, then pull pull bar, the first taper surface is against the first inner conical surface, and the second taper surface is against the second inner conical surface, expansion set two ends expansion swelling simultaneously workpiece, thus the processing carried out workpiece, this programme convenient mounting and clamping is quick, processing ease, tiller dust cover can be fixed fast, substantially increase production efficiency.
Further, pull bar is provided with anti-rotation groove along glide direction, axle body sidewall is provided with the anti-turn screw stretching into anti-rotation groove, prevents pull bar from rotating.
Further, the first inner conical surface is provided with chute, and the first taper surface is provided with spline pin, and spline pin inserts in the chute on the first inner conical surface, prevents from relatively rotating between expansion set and axle body causing work pieces process unstable.
Further, axle body left end is circumferentially with multiple installing hole, can be fastened on machine tool chief axis, facilitate installing/dismounting by bolt or screw.
