Description
Technical field
The utility model discloses a kind of plant equipment that is used for the boring taper hole, belong to the machining equipment technical field.
Background technology
Before the utility model was made, traditional machining equipment boring machine can not directly carry out boring to taper hole.The taper hole class part of some types, the aperture of its taper hole greatly and darker, if on horizontal boring machine it is processed, then the machining accuracy of part and working (machining) efficiency all are difficult to be guaranteed, and will have a strong impact on the assembly quality of parts.Traditional processing method is: at first the diameter dimension boring according to part taper hole small end goes out straight hole, slightly cuts with scissors taper hole with taper reamer then, finish reams taper hole by hand with bottoming reamer again when assembling.
There are some taper holes can adopt special-purpose boring cutter bar and anchor clamps, on horizontal boring machine, process.But special-purpose boring cutter bar and anchor clamps are made complicated, and technological operation is numerous and diverse, is unfavorable for industrial production in enormous quantities.
For up to ten thousand and even hundreds thousand of manufacturing batches, the special-purpose conic boring device that can process taper hole easily just seems very necessary.
Summary of the invention
The utility model provides a kind of taper hole boring lathe that can process taper hole easily at the deficiency of prior art.
The technical solution of the utility model is:
By seesawing of the tilting axis of guide in main shaft, limit the tapering variation track of boring, go out taper hole by the boring bar that is installed on the axis of guide along the track boring;
Designed and constitute gear-driven screw rod with main shaft and drive lining, cover, key successively, the pull bar promotion axis of guide that promotes to link to each other with key seesaws and finishes boring feeding, withdrawing;
Adopt the off-load belt pulley to finish the power transmission of main shaft, reduce main axis jerking, improve machining accuracy;
Dynamic balancing when having designed the balance weight solution main axis rotation that links with push-pull shaft compensates automatically.
Below introduce structure of the present utility model in detail: a kind of taper hole boring lathe comprises that headstock, main shaft and main shaft sliding bearing constitute, and is characterized in that:
Be equipped with one in the main shaft and be the axis of guide of angled bias with main shaft, one end of the axis of guide is equipped with a boring bar that axis is parallel with main-shaft axis, pull bar in the other end of the axis of guide and the main shaft is connected, and axis of guide outside has the axial keyway and the alignment pin of the interior fairlead of main shaft to be sliding connection;
Constitute gear-driven screw rod with main shaft and be connected lining, cover, key successively, and the pull bar that links to each other with key constitutes the pull bar transmission mechanism, promotion axis of guide boring feeding;
Adopt the off-load belt pulley to finish the power transmission of main shaft, reduce main axis jerking, improve machining accuracy;
Dynamic balancing when having designed the balance weight solution main axis rotation that links with push-pull shaft compensates automatically.
When the utility model used, main shaft rotated, and an end that is angled bias with main shaft in the main shaft is equipped with the axis of guide of boring bar, feeding under pull bar promotes, and boring goes out taper hole, limit switch restriction pull bar supplying position; The off-load belt pulley is finished the power transmission of main shaft, reduces main axis jerking, improves machining accuracy; The unbalance automatic compensation of main shaft that axis of guide feeding causes when solving main axis rotation with the balance weight of push-pull shaft interlock.
The utility model has the advantages that simple in structurely, control conveniently.Being fit to the fixedly taper hole of tapering in enormous quantities processes automatically.
