Description

"

The invention relates to the process equipment of automated assembly production and can be used in mechanical engineering and other sectors of the national economy.

The aim of the invention is to improve the reliability of the assembly by increasing the accuracy of the primary and relative orientation of the assembled parts.

FIG. 1 shows the proposed device, the cut; FIG. 2 is a section A-A in FIG. one; in fig. 3 - section bb in fig, .2; in fig. 4 knot clamping levers; in fig. 5 is a view of B in FIG. four; in fig. 6-assembled parts; in fig. 7 - assembled product.

The device comprises a housing 1, a magazine 2 with a cavity for coils, a magazine 3 with cavities for cores. The movable base wall 4 with the windows 5 and the fixed wall 6 fixed on the rack 7. In its lower part the wall 6 is provided with clamps 8 mounted on the axis 9,

pressing the springs 10 and 11 and pressing the core against two mutually perpendicular walls of the magazine. A pair of clamping levers 12 and 13 are installed under the presses 8, each of which has a groove 14 with the passage through it and. a pin 16 pressed into the housing 15. The diameters of the studs 16 are smaller than the width of the groove of the levers 12 and 13, and therefore the latter can rotate in the plane of the drawing within the gap between the groove and the pin (Fig. 1 and 6).

I

The levers 12 and 13 are pressed against the two springs 17 in the direction of the clamping wall 4 and are unfolded in the plane of the drawing (Fig. 3 and 7) by the spring 18. The movable wall 4 and the locking levers 12 and 13 are interconnected through the lever cam 19, mounted on axis x 20, the slots of the levers 12 and 13 are pressed into the housing 15. With its profile part, the copier 19 mates with the roller 21 fixed on the movable wall 4. The yoke 22 by means of the spring 23 provides the force closure of the wall 4 with a lever copier 19. Last h through tgu 24 is connected

55356

with a lever 25 mounted on an axis 26 (at point O) with a roller 27. In the lower part of the cavity for the coils there is a feeder for the coils, which is a junction box.

5 from a table 28 mounted on a rod 29 and a clamp spring gripper 30 fixed with screws on a rod 31. Table 28 has a stepped shape, and the distance

10 between its face and the step is equal to the distance between the clamps and the 4 cores grounded by the relative wall. The rod 29 and the rod 31 are installed together with the guide

15 32 on the strap 33 and have a single drive from the slider 34 with rollers 35, interacting with the strap 33 through the finger 36. The force closure of the cam with the roller 35 is performed

20 through the compression spring 37 and the rod 38 mounted in the glass 39 attached to the bar 33.

The orienting mechanism for the coils consists of catchers 40, clamps 41, decompressed by compression springs 42. The catchers 40 are pressed into the - bar 43 and are held by the protruding adjustment bolts 44 by the protrusions of their heads. The holes 44 that are aligned along the axis of the bolts 44 are pressed in by the 45 pins. The bolts 44 are screwed through the blocking rubber dampers 47. The sleeves 48 receive a movement from the forks 49 provided with the rollers 50. The solid coupling between the cams and the roller 50 is made by the springs 51.

The assembly position consists of two guide sleeves 52 in which the pushers 53 move. The guide sleeves 52 are made with flat elements 54 of the base of the assembled parts, half-cores. Pushers 53 receive movement from levers 55, which rotate on axles 56, located in plungers 57, which can be moved in housing 58 by the amount of compression of rubber locking pipe 59,. To remove levers 12 and 13 of fixation, lever linker 19 is equipped with two pin stops 60, pressed into the copier shoulders.

The device works as follows. Coils 61 are loaded into the cavity of the magazine 2. In the cavity of the magazine 3

the cores 62 are loaded. As a result, the lower coil is lowered onto the table 28. The column of cores in the cavities of store 3 as they descend is based on the movable wall 4 and the side walls of the cavities of store 3 with the help of clamps 8, which clamp the cores to the specified walls in two mutually perpendicular planes under the action of two springs 11 and one spring 1 o, the lower pair of cores, moreover, when exiting from the clamps 8, is also based on the clamping elements 54 of the sleeves 52. By its turn to the left, the gripper gripper 30 captures the lower in olbe coil parts, the wall 4 is in the uppermost position, cam 19 is turned to the extreme position in the direction of motion-clockwise. From the actuator cam through the roller 35, the bar 33, the gripper 30 together with the rod 29 and the table 28 are set to move to the right. The table 28 abuts with its end (the first track abutment) into the movable basing wall 4. The catchers 40, together with the clamps 41, move towards each other. The coil is initially placed between the clamps: 41, and then oriented in the gripper 30 by the catchers 40. Backwardly, the catchers 40, and then the clamps 41 release the gripper-oriented coil. The little table 28, by moving to the left, releases the wall 4, which due to the rotation of the copier 19 counterclockwise

lowered by an amount sufficient to allow the table to pass into the okNO 5. Planck 33, grip 30 with a coil, rod

29 and table 28 are moved to the right until the second track support (stationing steps of table 28) is pressed into wall 4. Since the distance between the first and second track stops equals the distance between the retainer axes and the phased cores, the tick-borne grip is with the coil being oriented with respect to the axis of the core assembly. When the copier 19 is rotated counterclockwise, the pin stops 60 release the locking levers 12 and 13, which, moving up the slots, rotate about the axes 20 counterclockwise until they stop at the cores, pressing them against the wall 4. The clamping elements 54 and along the wall 4 move the cores together with the levers 12 and 13, compressing the spring, and the locking rubber washers 59. The front part of the wrench is half in the bore. Copier 19, getting the opposite

(clockwise) rotation, the pin supports 60 lower the locking levers 12 and 13, while the cores, under the force of elasticity of the washers 59, are pushed by the push rods 53 into the hole of the coil. Tick capture

The 30th move of the bar 33 to the left carries the assembled link from the position of the assembly. The cycle is over.
