SU88795A1 - Automatic Countersinking Machine - Google Patents

Description

Countersinking nuts are usually produced on drill nn on lathes.

The proposed automatic machine for countersinking nuts feeds, countersinks and removes nuts from the machine automatically.

In order to automate the processing of the nuts, the machine is equipped with springs, pressing the working spindles through rollers to the distribution discs carrying curves and surfaces for removing the spindles, feeding the nuts to the holder sockets and dropping the nuts after countersinking.

The drawing shows a general view of the machine with the location of the left and right shpinddely.

From pin 1, the rotation is transmitted to shaft 2 through gears 3 and 4. From shaft 2 through tines 5 and 5, the rotation is transmitted to two shpindles 7, and through tines 8, 9 v. 10 - two shpinddel m //. The two spindles 7 have one guide 12 and move together. The other two types of case 11 (Fig. 2) each have their own guide. Spindle 7 rotates in one direction, and spindle // rotates in different directions, by means of parasitic pinion 10. On the shaft 2, the distributor disks 13 W. 14 eccentric 15, reinforced by means of brute force consisting of 16, 17, and 18 /five.

The working stroke of the spindles is carried out by means of springs 20, which press the working pieces by means of rollers to the distribution disks 13 and 14.

The distributor disk 13 has three curves on the nose nosepx, one of which retracts the spindles 7 back, first the nuts are fed to the holders 21, the second curve ejects the nuts from the holders 21, the countersinking of the nuts occurs at the same time. The spindles 11, through the roller 22, rest on the distribution disk 14, which performs two fuctions, the nut bolts and the spindles retraction. The third curve of the disk 13 during the retraction of the chapters 11 backwards causes the nuts to be dropped.

The nuts to be countersinked are poured into the reservoir of the bunker 23, from which, with the help of the distributor 24, they get into the magazine 25, and then into the holders 21.

The distributor 24 is driven by an cam / 5 and roller 26.

: No. 88795 P me .c me of the invention

An automatic countersink nut machine consisting of a frame carrying four spindles for fastening the cutting tool and distribution discs, characterized in that, in order to automate the process of countersinking the nuts, it is equipped with springs pressing the working spindles through rollers to the distribution discs m. there are curved surfaces on it for removing the spindle nipples, feeding the nuts into the holders' holders and dropping the nuts after countersinking.
