Description
The utility model relates to the automatic threading device of a kind of lathe, and it belongs to the machine tooling cutter arrangement.
Traditional mantle fiber operation has two kinds of methods:
The one, the hand die handle, the operator takes die handle on the other hand during operation, and shaking lathe stays the feed of plate case handwheel on the other hand, and lathe rotates stings cutter, and hand takes die handle to exert all one's effort plate.The danger of a careless slightly hand of will damaging, very dangerous.Because manual operations, mantle fiber are not just, the commentaries on classics degree is low, and is of poor quality, and labour intensity is big, inefficiency.
The 2nd, hand tail stock threading device though this method can guarantee diehead threading quality substantially, compares safety.But the main shaft of this device is an integral slab retainer, and separately, tail and cover body three parts, tail end is for putting into the tail stock hole, and head end is the chucking screw die.The operator shakes the feed of the tailstock seat handwheel during operation, and lathe rotates and stings cutter, drags whole tailstock and moves forward along the bed surface guide rail with collar bush.Because load is big, not only the lathe rotational speed is restricted, and to the heavy wear of lathe face guide rail, thereby has significantly reduced the service life of lathe.Simultaneously, labour intensity is still bigger, and operating efficiency is also lower.
The purpose of this utility model is in order to overcome above-mentioned weak point of the prior art, improve at the tail stock threading device, the automatic threading device of a kind of lathe is proposed, the integral body cover body that is about to main sleeve is divided into two parts, head and cover body front portion are divided into leading portion, and afterbody and cover part after one's death are back segment.Leading portion is the overcoat that endwisely slips, and back segment is the interior cover of taper shank guiding that has chute, and leading portion and back segment can be linked in together closely, are connected by guider screw, and the leading portion overcoat can slide before and after the back segment chute.On engine lathe during cover system screw, sting cutter after screw die along with moving automatically before and after the leading portion overcoat, back segment and tail stock are motionless, so just can finish the mantle fiber task automatically, use this device can improve 2～4 times of work efficiency.
The utility model is made up of cover, the overcoat that endwisely slips, threading die seat, screw die and guider screw etc. in the taper shank guiding.The size of cover afterbody taper shank according to the size in tail stock hole, can closely cooperate when making it pack the tailstock core retainer plate in the taper shank guiding; The cover front portion is a hollow bushing in the taper shank guiding, has symmetrical guide chute up and down in the sleeve pipe middle part.Endwisely slip the cover body of overcoat partly for hollow bushing, and its front end has spindle nose, has equally distributed four trip bolt holes on the spindle nose.The seat hole is overlapped as concentric garden with endwisely slipping with spindle nose in the spindle nose outer end, and the interior diameter of the outer condom body that endwisely slips will be a bit larger tham the overall diameter of cover hollow bushing in the taper shank guiding, promptly leaves the gap of cooperation.Near endwisely slipping the end of overcoat hollow bushing, have two with the taper shank guiding in the corresponding guider screw of the guide chute hole overlapped.The overcoat that will endwisely slip is enclosed within the taper shank guiding and puts, and making to endwisely slip that outer to put two guide chutes in putting two guider screw holes and taper shank leading corresponding, tightens with guider screw, and the hollow bushing of the overcoat that endwisely slips can be moved forward and backward along guide chute.
In order to enlarge the scope of mantle fiber, ad hoc meter one cover threading die seat.The outer end of threading die seat has equally distributed four trip bolt holes, in screw die is packed the threading die seat outer end into the seat hole after, four trip bolts of screwing on, again threading die seat is packed into and endwisely slip in the overcoat spindle nose outer end in the seat hole, the trip bolt of on spindle nose, screwing in uniform four trip bolt holes, make screw die, cover is concentric garden in overcoat and the taper shank guiding that endwisely slips, and promptly constitutes lathe of the present utility model with the automatic threading device of bushing type.
During the mantle fiber operation, cover tail end in the taper shank of the automatic threading device guiding is packed in the tail stock core retainer plate hole, pull to workpiece with being about to tailstock, fixedly tailstock starts lathe, rotates handwheel, after workpiece and screw die interlock, handwheel stops operating, and the outer interior cover of the taper shank guiding upper edge guide chute that is enclosed within that endwisely slips moves forward, and finishes axially feeding automatically, when screw die is cut to the Len req size, main shaft reverses rapidly, and screw die withdraws from workpiece, can overlap and make M

36Outside nut.
The utility model is simple in structure, and is easy to operate, safe and reliable.General workman's operation both can guarantee product quality, can increase work efficiency 2～4 times again, and alleviate working strength of workers greatly, had reduced the wearing and tearing of lathe guide rail surface, thereby had prolonged the service life of lathe.On engine lathe, utilize the spindle nose of this device, change socket and chuck, also can bore, mill, operation such as fraising.Mechanical repair plant or professional operation producer that the utility model is specially adapted to medium-sized and small enterprises use.
Below in conjunction with accompanying drawing the utility model is further described
