Description

P zssstyy machines d.d drilling of buttons, which contain also a bunker with a nested disk, days, where, sleeves, chutes, distributor. I wired, and a disk with grippers, 1 nodachi billets to the index of vertical spindle-set spindles back and forth motion. These machines have low productivity.

The proposed machine has a high productivity with simultaneous supply of blanks to all the saws and drilling of all the holes in pguiii with each drill with simultaneous ejection of all drilled buttons from under the spindle. The particularity of the machine lies in the fact that iodine diner bukker rdally installed in the guide working from the cam IALI d, 1 pulling the blanks from the sockets of the dinna to the directional distributor disk. Rotary cone clips are mounted in the disk for workpieces and the iris is arranged to periodically rotate them when the holes are drilled next time. The device for turning the cone clips consists of

central cam and a leverage system.

Pa figs. 1 is a schematic view of the machine is cut; in fig. 2- ciicpxy type; FIG. 3 - | Bottom line on LOL ia fn | -. 2; in fig. 4-section but BB and FIG. five; in fig. 5 is a sectional view of explosives in FIG. four; in fig. 6 is a sectional view of the ABC in FIG. 7; in fig. 7 -:) A cut-down on ABCGDE in FIG. 6; in fig. 8 - designed to rotate the conical lugs 15.

The machine contains a bunker /, li which is handled by nyiOBHu, on a conical bottom 2 with a disk 3, fitted with edges 4 on the edges.

The bunker joins the vibration from the eccentric 5 through 6 and 6: lever 7 d, 1 so that all the workpieces in the bunker part 1 should be in 1 jack 4 in the mountain 11: oita.

In one slot 4 of the disk 3 is placed simultaneously tpp; button blanks. This is done in order to have a stock of needles for dropping onto the drill hole and thereby eliminate the need for a good course of operation of the machine.

Under the bunker bottom / radnally

The fingers 10 from the cam 9 are installed in the guides A |), which serve for gztalkkvvanp logger 113 slots 4 of the bunker and feed them through 1), 1;

For compactness, a nest dipper, an e-bunker, and a distribution disc are horizontally spaced; 1 is located with a 1 cm by hinge on the bunker itself in the center of the machine.

Distribution DPSK /, with the help of cam 14, slider /; Snezhem r1z chagov 16, performs a rotation of 5-7 ° protpv clockwise, then m / i; part of the circle forward clockwise. During this movement, the disk 12 captures the workpiece and moves it along the plane of the fixed table 17 to the cone clamps / 6, equipped with an adapted for their ne | iodic rotation. The latter consists of a central cam 19, a slider 20 and a system of levers 21, 22, 23 and 24. The conical clips also perform an upward and downward movement by means of a disk 26 and a lever 27.

After finishing the workpiece to the clipping clamp, the distribution disc. The disk 12 returns to its original position, and the workpieces are fixed in a cone clamp. To turn the drill through, the indicated bite is rotated four times with pauses in time.

While drilling holes in button blanks, the spreading disc 12 does not rotate, and the tapered clamps are locked by retainer 28 due to the effects of the DISC 29 and the leverage system 30.

For drilling - the holes are vertically mounted, rotating retainers 31 with collet chucks for clamping drills. The reciprocating motion of the spindles is so.

On the main camshaft 32, there is a disc 33, which has a purpose to act on the disks 34 and 55 and cause them to move along the main distributor in r, y and 32.

 35, priodpp Kisepxy, clicks on the rocker 36, which is his own kitsom m and pressing the pnginel. The spindle with drill goes down. The drill, drill, drills the holes in the button magazine.

Through the chip drive, the drive disk 35 goes down, and the pindle rises up, the drill is released from the button hole. The cone clamp rotates L turn, i.e., 90.

The system of fur snakes, and turning the .u-ix button blanks in clamped cones, n the system of mechanics, iodnimayih and lowering their I1ppdell, interact in strict and consistent.

At the end of the button drilling process, the spreading disc 12 repeats movement 5-7 ° counterclockwise n 60 ° but clockwise. In this case, the movable button is drilled out of the raised taper clamp 18 by means of the hook 37. At the same time, the next button blank is fed by the clamp 13 under the taper clamp 18.

The machine has a pneumatic device for removing sawdust formed during drilling. The pneumatic device works by blowing the lisch at the moment when the button is clamped with a tapered clamp m.

The machine is driven by an electric motor 38, from whose pulley through a text-driven transmission, the rotation is transmitted by one belt to the drive column 39, and the second belt to the drive shaft of the gearbox 40, transmitting the main shaft 32.

Drive column 39 transmits rotation through a belt drive to pin 41 of one of the pinchings 31. All of the spindles are connected to each other, low by area.
