Abstract

The invention relates to mechanical engineering and can be used in automatic machines for a set of keys for locks. The aim of the invention is to increase the reliability of the assembly machine by providing the necessary orientation of the assembled set of keys when moving it to the gripping groove of the conveying turntable. For this, the swivel hook grip body is provided with a spring-loaded lever 21 mounted on the swing arm 17 with the ability to mate with the slotted guide 24. After the set of the required number of keys on the hook hook 20 is completed, the lever 17 is rotated counterclockwise. At the same time, the lever 21 enters the slotted guide, in which the keys hanging on the grip 20 are also located. As a result of turning the lever 17, the pusher 23 moves, which moves the set of keys oriented by the lever 2 in the guide 24, into the turning groove tables 9. 4 ill. (Oh (Oh

The invention relates to mechanical engineering, can be used in the manufacture of keys for locks, and is an improvement of the assembly machine according to ed. St. No. 1273227.

The aim of the invention is to increase the reliability of the assembly machine by providing the necessary orientation of the assembled set of keys when it is moved to the catch hole of the conveying turntable.

FIG. 1 shows the kinematic scheme of the assembly machine; in fig. 2 is a view A of FIG. 1 (key set dialing mechanism in the set dialing process): in FIG. 3 - the same, at the time of installation of the kit in the radial groove of the table; in fig. 4 view B in FIG. 3 (slit)

The machine contains a frame (not shown) with the drive 1 installed on it and kinematically connected (Fig. 1) and between itself the mechanism 2 of the long-length material, the mechanism 3 bends the spring coil, the mechanism 4 wire cuts, as well as the mechanism for supplying piece-and-key keys, which includes the transfer mechanism 5 and transport p (then 6.

from the transport rotor 6 of the mechanism for supplying piece keys 25. At the same time, the gate feeder of the loading mechanism 5 transfers the next key 25 to the gripper 26 of the transport rotor 6.

At the time of loading the key in the grip 26, the transport rotor is stationary. Further, as the rotor 6 rotates, the keys 25 are successively supplied by the grips 26 of the transport rotor 6 to the key collection set mechanism 7. From the shaft 12, the rotation is transmitted to the cam 11. As the shaft 12 rotates, the profile cam 11, which interacts with the lever 14, rotates it around the finger 13. At the same time, the lever 14 doesn’t move along the axis pn 15, which acts on the roller 16 mounted on the two shoulders the lever 17 rotates the latter around the axis 18. The lever 17 rotates the hook grip 20 into the head opening of the key 25 installed in the grip 26. Then the grip 26 moves along the axis to the center of the transport jute 6. Since at the moment of movement of the grip 26 The second end of the hook grip 20 is inserted into the hole of the head of the key 25, then the key is removed from the grip 26 and slides off with the hook grip 20 to the radial groove 10 of the table 9. At the same time, the key stem 25 ||) is inserted into the slot groove || ) aw, | hook, hook 20 is oriented relative to the axis of the base |); 1dial groove 10 of the turntable 9. L; 1lever as the cam 11 nriaid a 15 is turned lowers, the double-arm lever 17 goes along the axis 18 in the opposite direction. 1enii, with an atom, the free end of the hook grip 20 is withdrawn from the zone previously known: 1 hectare () from the grip 26 of the key 25, and the subsequent grip 26 with the key 25 is inserted into the released zone. With further rotation of the cam 11 and the tanga 15, the free end hook grip 20 is inserted into the hole of the turn of the key 25 included in the kit. Since the set of keys consists of five 1ptek, for one revolution of the cam 11, the transport rotor 6 performs five fixed turns on a given angle. The removal of keys 25 from grippers 26 is also repeated five times. When the last key is removed from the grip 26, the double-arm lever 17 rotates to a greater angle, while the spring-loaded lever 21 attached to the second arm of the pivoting lever 17 slides along the surface of the slotted guide

25, and the pusher 23, connected by means of i and tipper 22 with second arms of lever 17, pushes the set of keys 25 into the radial groove 10 of the table 9, at the same time having free gear;

The gripper 20 is withdrawn from the holes of the keys of the assembled set, which corresponds to one complete revolution of the cam 11.

At the beginning of the next rotation of the cam 11, the table 9 is rotated, moving the next set of keys 25 to the working position of the feed mechanisms 2 of a long material, bending 3 spring rings and the notch 4 wires.
