Description

The invention relates to a machine tool industry, namely, to automatic machines for finishing machining of cypinaric parts. Automatic machines are known that contain a magazine with a cutter, a feeder, a mandrel with an ejector, and a diverting box I. These machines are intended for details of a simple form and cannot be used for machining shaped sleeves that rotate the shoulders on the outer surface. Automatic machines are also known that contain a collet chuck with a spring-loaded ejector, a magazine with an orbital cutter, a feeder and a receiving tray with a Fixed stop for dropping parts 2. These machines are also not without the above disadvantages. In order to expand the technological capabilities of automatic machines for finishing parts like bushings, the proposed machine is equipped with limiters installed in the store, orientators, and the ejectors are made in a vipok hinged on the collet chucks, moment of dropping the part. FIG. 1 shows the proposed device, a general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. 2; in fig. 4 is a section, B-B in FIG. 2; in fig. 5 - Vic according to arrow G in FIG. 3; in fig. 6 is a modification of one of the components of the assembly in FIG. five; in fig. .7 view along arrow D in FIG. 2; in fig. 8, section EE of FIG. 7; in fig. 9 is a section of an LF in FIG. 7; in fig. 1O — Collet Chuck Section. On the base 1 of the automaton, the body 2 is fixed, in the bearings 3 of which the drum 4 is mounted, and in the sprockets 5 there are mounted spindles 6 with collet chucks 7 and ejectors 8 in the form of forks,

loaded with springs 9. In the two upper collet chucks 7, parts 10 are held in the machining position.

On the frame 1 fixed stand 11 with a feeder in the vice of the hollow stem 12 and the pusher 13, and the rod 12 carries the loader 14, and the pusher - the head 15.

At the entrance and exit of the magazine 16, limiters-orientators 17 and 18 are installed, and a cutter 19 connected by a pin 2O through the elastic element 21 to the lever 22, upwardly operates in turn with an adjustable stop 23 on the bracket 24, the loader 14,

Receiving tray 25 is installed with the possibility of rotation and reduced by the safety device 26, the fixed stop 27 and the visor 28.

If necessary, the safety device 26 can be made in the form of a rotary prism 29, spring-loaded spring 30.

The collet chuck 7 is equipped with an internal cone 31, which cooperates with a clamping cone 32 fixedly mounted in the spindle 6 by means of a pull rod 33 and a head 34. The 3S tool in the form of superfixed bars is fixed in the swing arms of the 36 working heads.

The machine works as follows. When machining parts 10 in the two upper collet chucks 7 with tool 35, in the lower cartridge, the machined part is removed by forks of the ejector 8 and dropped into the safety device 26 (or prism 29) of the receiving tray 25. When the receiving tray 25 is rotated, the fixed stop 27 pushes the component H from the catcher 26 (or prisms). At the same time, the rod 12 moves the loader 14c with the raw part 10 to the end of the lower cartridge 7, and the pusher 13 pours it into it; At BTO, forks 8 are pushed out.

244

After clamping parts 1O in the collet chuck 7, the rod 12c by the pusher 13 is moved to the right, and the bracket 24 through the screw 23, the lever 22 and the pin 20 interacts with the slam-shutter 19, which passes the next part from the magazine 16 to the loader 14. The limiters orientators 17 and 18 prevent 16 incorrectly oriented parts get into the store and limit their axial displacement when they are delivered to the loader 14.

After finishing the processing of parts 10 in the upper collet chucks 7, the tool 35 is retracted, the drum 4 is rotated at an angle of 120, and the receiving tray 25 rises to its original position. The cycle of the machine repeats.

invention formula

A machine for processing parts such as sleeves containing collet chucks with spring-loaded ejectors, a magazine with a cutter, a feeder, a receiving tray and a fixed stop for resetting parts, characterized in that it is equipped with in-store limiters orientators , and the extractors are fixed in the form of hinged fasteners on the collet chuck, forks, and the receiving tray contains a safety device that interacts with a fixed stop at the moment of dropping the part.
