Description

The invention is intended for processing plastic products and can be used in enterprises of local industry producing dominoes and the like. products.

The aim of the invention is the expansion of technological capabilities.

FIG. Figure 1 shows schematically the kinematic diagram of the automaton; in fig. 2 is a view B in FIG. one; in fig. 3 shows the node I in FIG. one; in fig. 4 - product - domino chip; in fig. 5 - mounting rod in the shaft; in fig. 6-8 - two-stage pusher in operation; in fig. 9-10 - interaction of the spindle with the program disk.

The multi-spindle boring machine contains a frame on which the loading device 1 is mounted, a spindle drive unit 2, a vertical shaft 3 inside which the rod 4 passes, a non-driving software disk 5. In addition, the machine includes a chip-pushing unit 6.

The device for removing chips and dust contains a dust extraction system 7 and a blowing system 8. The camshaft 9 is driven by an electric motor 10 through a safety clutch 11, a gearbox 12, a chain drive 13, in one of the sprockets 14 of which the overrunning clutch 15 is integrated.

On the camshaft 9 are located the cam 16 of the drive of the loading device 1, the cam 17 for driving the rod 4 with the program disk 5 into translational motion of the cam-fuck 18 for turning the vertical shaft 3, the cam 19 of the blowing system 8, the flywheel for manual rotation when adjusting the machine.

The cycle of the machine corresponds to the time of one revolution of the camshaft 9.

A rotary table 21 is mounted on the vertical shaft 3, which consists of a 32-position disk, twenty-eight positions of which are equipped with floating jigs 22, which are fixed with the possibility of precise drilling installation, and a disk 23 for turning the vertical shaft with evenly spaced about thirty-two rollers circumferentially 24. The stem 4 is fixed in the shaft 3 with the possibility of synchronous rotation together with the shaft 3 and the translational movement up and down from the fist 17.

Coaxially with a vertical shaft 3, a spindle drive assembly 2 is installed on the bed. The assembly contains fourteen 1b spindles 2 with drills 25 (according to the number of hole positions in the domino set) arranged according to the position of the holes “A” (FIG. 4) in the domino set “B, Fourteen radial transfer arms 26 serve to drive the spindles 2 into a downward translation — working stroke — from the program disk 5 up — idling — from the spring 27. To drive the spindles 2 into rotation, the machine is equipped with an electric motor 28 with a belt th transmission 29 consisting of two belts, each of which is designed to rotate the pinion 30 through the parasitic seven spindles 2.

The ejection unit 6 of the finished chips consists of a rail 31, two gears 32 and 33, one of which is equipped with a lever 34, half-pusher 35 and spring 36.

To receive the finished chip and transport it to the place of control, there is a receiving tray 37, a grooved tray 38, a lever 39 and a spring 40.

The boot device 1 contains a quick-detachable hopper 41, a cut-off valve 42 with a spring 43, a two-stage pusher 44, a plate 45, a lever 46, a spring 47.

To prevent domino chips from being pushed out of the bunker in the zone of four free positions of the 32-position turntable 21, the copier 48 is fixed on the latter to turn the lever 49 and stop the two-stage pusher 44. To return the lever 49, spring 50 serves. shaft 9

f. The lever 51 serves. The pins 52 are fixed on the plane of the disk 5.

The device for removing chips and dust contains a dust extraction system 7 representing a receiver-duct with fourteen tubes connected to the dust extraction unit.

0 drilling zones, and a blowing system 8, representing an annular air duct with fourteen tubes, to the drilling zones and one tube for blowing through the conductor 22 after ejecting the finished “B. The machine works as follows.

5 From the electric motor 10 through the safety II, the gearbox 12, the chain gear 13 with the overrunning clutch 15 integrated in the sprocket 14, the rotation is transmitted to the camshaft 9, the cams 16-19 of which and the flywheel 20 actuate

0 automatic.

From the cam 16, through the lever 46, a two-stage pusher 44 of the loading device 1 is received to move forward. The pusher 44 is made two-stage.

5 to reduce stroke.

When the pusher 44 moves forward, the end of the lower step pushes the chip "B" into the jig 22 of the turntable 21, while the end of the upper step pushes the chip "B out of the quick-release bunker 41. When the pusher moves back, the slam-shut 42 and spring 43 cuts the chip and it lowers onto the plate 45 .

As the pusher travels forward, the cycle repeats. The working stroke of the pusher - pushing the tongue from the spring 47, the hollow 5 of that move - back from the fist 16.

Pisces are pushed into conductors at twenty-eight positions of a 32-position turntable.

On the four free positions of the turntable under the action of the copier 48, the lever 49 turns and stops the two-stage pusher — the chip is not fed to the turntable. The return of the lever 49 - from the spring 50.

The fist-lug 18, acting on the rollers 24 of the 32-position disk 23, drives the vertical shaft 3, the rod 4 with the program disk 5 and the rotary table 21 fixed on the shaft 21 with twenty-eight conductors 22 into pulse rotation, turning it in one cycle by 1 / 32 turns.

During vysto software disk 5, mounted on the rod 4, receiving the translational movement up and down from the fist 17, through the levers-translation 26 causes the spindles 2 of the drive unit drills 25 in translational motion: down - working stroke (drilling) - from the software disk 5 , up - idling - from the spring 27.

In this case, the program disk 5 with the corresponding pins 52 interacts with the corresponding ends of the transfer levers 26. If, under the lever of the transfer lever, there was a pin of the program disk, drilling occurs, if not, the transfer lever into the corresponding spindle is fixed, drilling does not occur. When moving the rod 4 with the program disk 5 down, all the spindles with drills 25 are returned to their original position by the action of the springs 27. For a complete rotation of the vertical shaft 3, the tongue in the conductor passes successively past all the spindles, which drill the required number of holes in it according to a predetermined program.

The rotational movement of the spider is obtained from the electric motor 28 through a belt drive 29 and parasitic gears 30. With the forward movement of the rod 4 with the program disk 5, the latter drives the track 31 of the ready-to-push piece assembly 6, which through gears 32 and 33, into translational movement half-pusher movement 35. Working stroke — pushing out the finished chip — from rail 31, idle — back — from spring 36.

A domino chip "B" is pushed out of the conductor 22 into the receiving tray 37, and then, under the action of the lever 39, is transported along the grooved tray 38.

to the place of control. Lever 39 receives a rolling motion from the turntable 21, for each cycle shifts the domino chips “B” by a step equal to the width of the chip. The return of the lever 39 is from the spring 40. From the fist 19 of the shaft 9, periodically when lifting the drills, the system 8 is blown off. The system 7 dust suction works continuously when the machine operates. In the following, the cycle repeats.

The use of the device enables the automation of drilling operations in a wide range of hole locations on the chips with improved working conditions and culture.
