A kind of automatic feeder of lathe

Technical field

The utility model relates to a kind of automatic feeder of lathe, relates in particular to a kind of automatic feeder of processing the lathe of bar shaft-like workpiece.

Background technology

At present, though its processing work of miniature numerical control lathe such as numerical control instrument lathe has realized automation, but the discharging after its material loading and the processing still needs manually to operate, can not realize the automatic feed of bar shaft-like workpiece, therefore big, the poor stability of labour intensity, production efficiency are low, are not suitable for producing in enormous quantities processing bar shaft-like workpiece.

For this reason, it is that the Chinese utility model patent " a kind of full-automatic numerical control lathe " of ZL96227272.8 (notification number is CN2252079Y) has disclosed a kind of such structure that one patent No. is arranged, a kind of full-automatic numerical control lathe, comprise feeding and material-pulling device, the bin stock disk of pay-off links with the support that is fixed on the spindle stock side, on the common mandrel of bin stock disk and support disc spring and driving lever is installed; The discharging opening of bin stock disk bottom is connected with the material road; Feed appliance is provided with a semicircle or other is similar to the breach of workpiece profile; The forked end of fork is stuck on the round pin of feed appliance; The moveable hinge chain type block and the push rod of material-pulling device are installed on the lathe carriage, and push rod has tooth bar and is meshed with little sector gear; At lathe tailstock sleeve Inner Front End push rod is installed, sleeve rear end is fixed with tooth bar and is meshed with big sector gear; Large and small two sector gears connect with key.Overcome the shortcoming that existing numerically controlled lathe can not automatic loading/unloading, improved production efficiency greatly.But the feeding of this lathe and material-pulling device are made of the complicated mechanical drive mechanism, and this mechanical transmission structure relates to that parts are many, transmission is complicated, cost is high.

Also having a patent No. is that the Chinese invention patent " a kind of automatic feeding device for lathe " of ZL200510061651.2 (publication number is CN1775430Y) has disclosed a kind of such structure, by the discharge parts that are contained on the lathe, the storage bin parts, a kind of automatic feeding device for lathe that drive disk assembly is formed, the discharge parts are above the headstock of lathe, and be connected with the storage bin parts by the passage of discharge parts, the storage bin parts are positioned at the top of headstock spindle, the base plate of storage bin parts is fixed in the upper cover plate of headstock, drive disk assembly is positioned at the opposite side of headstock, drive disk assembly is moved by the transmission mechanism control on the lathe, the workpiece to be processed of drive disk assembly control storage bin parts falls, it is characterized in that liftout parts in addition, liftout is towards parts and driving member thereof, the liftout parts are contained on the storage bin parts, the ejector beam of liftout parts can be over against the workpiece to be processed in the storage bin parts, liftout is contained on the lathe rear base plate towards parts, liftout can be over against the liftout parts towards the jumper bar of parts, make the ejector beam action of liftout parts, liftout is connected with driving member towards parts, driving member also is contained on the rear base plate, by the transmission mechanism control action of lathe, driving member control liftout is towards the jumper bar axially reciprocating of parts.It has, and feeding is fast, and feeding stability is good, and feeding efficient height can improve the automaticity and the production efficiency of lathe greatly, is specially adapted to the automatic processing of short and small shaft-like workpiece.The drive disk assembly that this automatic feeding device for lathe relates to is made of cam, roller wheel, connecting elements, adjustment means, and structure is more complicated also, and it is also numerous and diverse, stable bad that whole drive system is moved.

In sum, the automatic feeder on the existing machine tool also can improve further.
