Description

The present invention aims to improve the performance of machine tools manufacturing coils, for which two rotary disks are used, between which electric motors and spindles with drills are fixed. On the axles of electric motors, mandrels are mounted on both sides, and on one side there are circular saws and pulleys for the transfer of vra; the spindles mentioned above with drill bits. Workpieces cut by a circular saw, automatically, using a pusher, go over the chalice and clamped between one of two pairs of discs designed to periodically rotate the workpieces, this results in leading the workpieces to the spindle drills to drill the central holes and then feed them into the molds coils.

In the schematic drawing of FIG. 1 shows a side view of the proposed machine; FIG. 2 is a front view thereof, and FIG. 3 is a section along line a b in FIG. one.,

Between the two frames 1 (Fig. 1), connected by bars 2 and 3, shaft 4 is mounted in bearings 5; Two disks 6 are rigidly mounted on this shaft, between which, along the circumference of a pa, the same distance is fixed

ten electric motors 13 carrying on their axes on both sides of the mandrel 16, and on one side circular saws 18; Ten spindles 15 are attached to these disks 6, the axes of which are provided on both sides with drills 17, at which the spindles 15 are rotated by means of a belt drive, an envelope, as shown in FIG. 2, two pulleys 14 of the motors 18 and two pulleys of the spindles 15. On the top and the bottom of the machine on the supports 9 there are four grooves 8 (Figs. 1 and 2), intended for feeding the bars; Each chute for advancing the bars to the saws 18 is provided with a special device in which the grooved roller 50 (Fig. 1) receives a periodic rotation from the ratchet 46, 45, 44, a chained dog 46, the curved end of the 47th one is under the influence of passing it when the rotation of the disk 7 of the sleeves 20 (Fig. 3). E-bars m 2 and 3 having cut mandrels 16 in four places are attached rods 35 (Figs. 1 and 2), in which a square 70 carrying the plastic plate 74 with the gripper under the action of the springs 71 and 72 can move along the arms; angle 70 is hinged to the lever 86-68-67,

on the end of which 67 periodically presses the supporting mandrel 16 cartridge 73.

The fixture feeding the workpieces to the drills 17 and to the mandrels 16 consists of two pairs of disks 24 and 26, of which the disk 24 is rigidly fixed in the support 22 (Fig. 1), and the disks 26 freely move along the roller 23 with two rods 27, through the support 22, connected to the disks 25, freely mounted on the rods 21. In the holes of the disks 7 are placed an annular axle 42 (Fig. 3), interconnected by two diametrically spaced bushes 20, through which the rods 21 are passed with the rollers 30, concluded in fixed fist guides 32. Between the discs 7 is placed attached respectively to the bars 2 and 3 of columns 38 (FIGS. 1 and 3) with the slider 39 connected to lever 75, 76, the springs 77 are not conductive rod 40.

The operation of the machine is as follows: when the disks 7 are rotated, the sleeves 20 press the curved end 47 of the rod 46 and the ratchet mechanism 46, 45, 44 with the grooved roller 50, which advances the bars along the grooves 8, causes an intermittent rotation; due to the action of springs 71 and 72 on the plate 74 of the square 70, the blanks are cut by saws 18 are taken from the nile node and transferred into the space between the disks 24 and 26, which is achieved due to the pressing action of the cartridge 7 3 at the end 67 of the lever 36 - 68-67, articulated with angle 70; The fixture described above is returned to its original position by the spring 37. The blanks clamped between the disks 24 and 26 are directed to the drills 17 by means of bushings 20, which, when the disks 7 rotate, press the curved end 77 of the lever 75-76-77, which moves the slider 39 downwards, as a result , under the action of the lever 40, the ring axle 42, and with it, the workpieces are rotated 180 and fed to the drills 17 spindles 15 for drilling

central holes. The axial feed of the blanks is carried out by the rollers 80 moving in the fist guides 32. After drilling, the blanks for processing them into the form of coils fixed by means of cutters 55 installed in the holders 53 with the cutters 55 are fed from the drill back to the mandrel 16, in the same manner as described above, those. by means of an annular pin 42 and lever 75 - 76-77.

The machine is driven by an electric motor 56 (Fig. 2), connected by means of a tape drive and two bevel gears 61 and 62, with a disk 6 fitted with a screw-cutting.

The subject of the patent.

1. A machine for making coils, characterized by the use of a pair of disks 6 (Fig. 1-B) receiving, using conventional gears, along with axis 4, rotation at a constant speed from the engine and carrying electric motors 13 between them (Fig. 1) , on the axis of which mandrels 16 are mounted on one and the other side, and on one side there are round nicks. the drills are supplied by pushers 70 (fig. 2) of the workpiece cut by saws 18 from automatically advanced along the 8 bru In order to clamp these blanks between one of two pairs of disks 24, 26, connected with diametrically located bushing 20, which are connected to each other, they are connected to each other by ring pins 42 (FIG. 3), which have onors in two located on the sides the main part 6, which are rigidly connected to the axis 4 of the disc 7 (Fig. 1) and intended to periodically rotate 180 blanks, in order to supply them to the drills of the spindles 15 for drilling the central holes and then transfer them to the mandrels 16-for machining the blanks in the form of a coil is not fixed anovlennymi cutters 53 in the holder 55 (FIG. 2).

2. In the machine tool described in paragraph 1, use the attachment to feed 18 bars to the saws in order to cut blanks from them, consisting of a grooved roller 50 (Fig. 1), which receives a periodic rotation from the ratchet 46, 45, 44, in which the bent end 47 of the dog 45 supporting rod 46 is knocked by the impact of the sleeves 20 passing by it while rotating the disks 7 (Fig. 3).

3. In the machine tool described in paragraph 1, use TOviKa4a for feeding workpieces consisting of a square 35 guided (Fig. 1 and 2) square 70 carrying a plate 74 with springs 71 and 72 serving as grippers serving: 1 ) to receive the workpiece from under the saw; 2) to transfer this workpiece into the space between the disks 25 and 26 under the action of the lever 36 - 68 - 67 connected hingedly to the square 70, by pressing on its end 67 of the cartridge 73 supporting the mandrel 16 ,

and 3) to return to its original position under the influence of the spring 37.

4. In the machine described in paragraph 1, the use of a device for transferring blanks to drills 17 in order to drill holes and to mandrels 16 for further processing, consisting of two pairs of disks 24, 26, of which the first is rigidly fixed in support 23 (Fig. 1), and the second is guided in this support by rods 27 and is influenced by passing through the sleeve. 20 rods 21 from the rollers 30 at the end, moving, when the disks 7 rotate, in fixed canal guides 82, in order to communicate axial movement to the workpieces when they are drilled or put on the mandrel, and the transfer of the blanks from the drill to the mandrel is made by turning 180 sleeves 20 by a spring rod 40 (Fig. 8) connected with a slider 89, which in turn is connected to the lever 75-76-77, which is influenced by passing by it, as the disks 7, sleeves 20 rotate.
