Automatic feed gets lathe tailstock boring axis aperture

In the axis kind in the spare parts, have there is aperture to need to machine among many axis. The treatment method with axial the commonnest aperture is: In lathe tailstock jacket places bit, hand brace aperture, make up in tool carrier next boring cutter, undertake car boring is machined. This kind of method is versed in to more shallow oily Kong Jia very convenient, treatment precision also can assure. But deeper to those axis aperture, it is very difficult that treatment rises. On one hand, the hand shakes when tailstock bore, tailstock sleeve distance is very short, when the hand shakes feed reachs sleeve journey limit, must shake again time, push before will whole tailstock, next again the hand shakes treatment. Undertake repeatedly so, labor strength is great, efficiency is very low. On the other hand, when precision work needs after be being gotten, because get the limitation of tool carrier dimension, boring cutter arbor is very fine, if aperture is deeper, criterion the stiffness of boring cutter is very poor, treatment precision is very poor, cannot machine at all even. Deep aperture is machined on lathe, the means of settlement that is not worth a problem to arbor stiffness normally is, tailor-made one arbor, load tailstock aperture inside, the hand shakes tailstock undertakes boring, its treatment process and bore are same, need to undertake repeatedly. Such, labor strength is very great still, more important is, because need to relapse intermittence feed, and the hand shakes feed speed is impossible also very even, treatment precision and exterior surface roughness are poorer, the quality with higher short of asks. Accordingly, to general small-sized plant character, treatment axis kind of deep aperture optimal settling way is change one's costume or dress lathe slightly, make tailstock can automatic feed. Should make lathe tailstock can automatic feed, can design a variety of improvement plan, among them a kind of the simplest way is will tailstock and procrastinate greatly board between add outfit receive board have rigid connection, such, should procrastinate greatly board when undertaking fore-and-aft feed, tailstock advances subsequently, realized the motor-driven feed of tailstock. Use this method to should note the problem below: At ordinary times, be in when tailstock locking handle when loosening the position, the locking below tailstock is pressed piece with lathe there is space between slideway. And when handle is in locking position, press a slideway be been in by impaction to go up, attrition power is very great. So, must adjust press an adjustment that go up nut, make tailstock locking handle is in locking when, pressure piece with clearance is not had already between slideway, do not have locking force again. Use this kind of method, can realize lathe motor-driven feed to machine deep aperture, rose to machine quality and productivity already, reduced labor intensity of the worker greatly again at the same time. And machine tool itself did not do any altering almost, do not need to improve cost, do not destroy any component with original lathe. If want a machine tool to restore original turning function, need to tear open next receiving only board, adjust again press below tailstock piece adjust nut returns former position can, very convenient.
