Abstract

The invention relates to the field of machining materials by cutting and can be used in metal-cutting machines for feeding billets in the machining zone, having the form of rotation bodies with a central hole. The purpose of the invention is to simplify the design of the feed cartridge. In case 1, an opening 8 is made, offset from the central opening. In the hole 8 there is a piston 10 spring-loaded with an elastic element 9 with an annular pusher 11 rigidly fixed on it, which encloses the collet 2. The piston cavity 5 of the hole 4 and the over piston cavity 12 of the hole 8 are interconnected. 1 il.

The invention relates to the processing of materials by cutting and can be used in metal-cutting machines, for example, automatic lathes for feeding blanks in the form of bodies of revolution with a central hole.

The purpose of the invention is to simplify the design of the feed cartridge.

The drawing shows the cartridge, General view, cut.

The feed cartridge contains a cylindrical body 1, in the central hole of which a collet 2 is installed with a piston shank 3 located in its hole, installed in a cylindrical hole 4 made in body 1, a piston cavity 5 of which is connected to the external line by a system of channels 6 and 7 supply of working fluid

The housing 1 also has a piston 10 biased with respect to the central bore 8, in which a piston 10 is mounted spring-loaded with an elastic element 9 and a ring pusher 11 rigidly fixed on it, which encloses the collet 2. At the same time, the piston cavity 5 of the hole 4 and the over-piston cavity 12 of the hole 8 interconnected.

The device works as follows.

A cartridge with an annular billet 13 secured on the collet 2 is conveyed by a manipulator (conventionally not shown) to the receiving collet 14 of the cutting machine and is aligned with it. Then, through channels 7 and 6, the working fluid (fluid) is fed under pressure into the super-piston cavity 5, which causes

Moving the piston 3, the shank of which releases the collet 2. At the same time, the working fluid is also fed into the super-piston cavity 12, as a result of which the piston 10 is moved and the push rod 11 rigidly attached to it pushes the workpiece 13 from the collet 2 to the receiving collet 14 of the machine.

Subsequently, the fluid is drained from the supra-organ cavities 5 and 12 and the manipulator changes the cartridge into the loading zone, in which it captures the next billet, and inserts the collet 2 into its opening. At the same time, during the axial movement of the cartridge, the billet 13 will act on the pusher 11 , shifts it to its original position.

Claims (1)

Invention Formula A feed cartridge comprising a housing in the central opening of which a collet is fixed with a shank of a piston installed in it, installed in a cylindrical opening made in the housing, the piston bore associated with a system of channels for connecting the working fluid to the external main line, as well as The housing has a spring-loaded pin with an annular pusher fixed on it to the collet, which is characterized in that, in order to simplify the construction, the pin is designed as a piston, and rofessional them and openings nadporganeva cavity surface bonded to the cylindrical cavity above the piston apertures.
