Abstract

The invention relates to devices for marking products and can be used in various branches of mechanical engineering. The purpose of the invention is to increase reliability, the pneumatic cylinder 2 moves the carriage 10 along the guides 9 until it stops against the stop 12. Then, under the action of the pneumatic cylinder 2, the lever 4 rotates the cam 5, which presses on the roller 6 and lowers the actuator 7 with the stamping elements 8 onto the part 25. Occurs marking. At the same time, the pin 14 of the bar 15 enters the hole of the limiter 12. During the reverse stroke of the rod 3 of the pneumatic cylinder 2, the lever 4 rotates, the roller 6, rolling around the cam 5, rises together with the actuator 7 under the action of the springs 28. The pin 14 of the bar 15 leaves the hole of the limiter 12 and the carriage 10 moves to the limiter 11 and stops, and the lever 4 rotates the cam 5 again, the roller 6 with the actuator 7 is lowered and the stamping elements 8 are in contact with the cushion 22 of the bath 21. A new paint is applied and the cycle is repeated when a new part 25 is fed. . 1 s.p. file, 3 ill. Ј СО С VI H VJ Yu Yu Yu

Description

The invention relates to devices for marking products and can be used in various branches of mechanical engineering.

A marking device is known which comprises a stigma holder, a paint bath, a wetting roller, a clamp consisting of a pneumatic cylinder, levers and an axis, and disks mounted thereon, supporting the adhesive holder.

Closest to the technical essence of the invention is a device for marking parts, comprising a frame, an actuator in the form of a pneumatic cylinder mounted on it, a lever connected at one end to a rod of the latter, a cam fixed to its free end, a roller for interacting with the latter, stamping elements, axial movement of the latter and stroke limiters.

A disadvantage of the known device is its low reliability due to the complexity of controlling the marking process.

The purpose of the invention is to increase reliability.

This goal is achieved in that a device for marking parts, comprising a frame, an actuator in the form of a pneumatic cylinder, connected at one end to the rod of the last lever, mounted on its free end, a cam, a roller for interacting with the latter, stamping elements, axial movement drive the latter and the stroke limiters, equipped with guides and a carriage mounted on them, the movement of the stamping elements is fixed on the carriage, the roller on the drive, and the travel stops on the guides, in addition about, the device is provided attached to the drive elements moving the stamp strip with pins for periodic interaction with stroke limiters.

In FIG. 1 shows a device for marking at the time the carriage stops above the part; in FIG. 2 is a part of the marking device at the time of imprinting on the part; FIG. 3 is a section AA in FIG.

The device for marking parts contains a frame 1, a drive mounted on it in the form of a pneumatic cylinder 2, a lever 4 connected at one end with its rod 3, a cam 5 mounted on its free end, a roller b interacting with it, mounted on an axial displacement actuator 7 elements 8, guides 9, a carriage 10 mounted on them, on which the drive 7 is fixed

axial movement of the stamp elements 8. On the guides 9 there are limiters 11.12 of the stroke of the carriage 10 having holes 13 for interacting with

pins 14 of the bar 15 fixed to the actuator 7. The stamping elements 8 are axially spring-loaded with springs 16.17 mounted on the guides 18.19 mounted on the actuator 7.

The guides 9 are fixed on the housing 20, having on the carriage 10 side of the bath 21 with stamp pads 22 and mounted on the bracket 23, made with grooves 24 for raising and lowering the housing 20, which allows marking parts 25 of different heights. The bracket 23 is mounted on the frame 26 of the stepping conveyor 27, which periodically moves the parts

0 25.

The device operates as follows.

Parts 25 are stepped conveyor 27 fed to the marking position, triggered

5 switch (not shown in the drawings) and gives a signal to turn on the pneumatic cylinder 2. The rod 3 of the pneumatic cylinder 2 through the lever 4 first turns the cam 5, the roller 6 goes into the cavity of the cam 5, the drive 7 under

0 the action of the springs 28 raises the stamping elements 8 from the baths 21 with stamping pads 22. The pin 14 of the strip 15 leaves the hole 13 in the limiter 11 and the carriage 10 moves along the guides 9 to the given details 25. At the end of the stroke, the carriage 10 abuts the limiter 12 and stops, and the lever 4, under the action of the pneumatic cylinder 8, rotates, rotates the cam 5, which presses on the roller 6 and lowers the drive

0 7 with stamping elements 8 on part 25. The marking process is taking place. Simultaneously with the lowering of the actuator 7, the pin 14 of the strip 15 enters the hole 13 of the limiter 12. At the end of the marking

5, the rod 3 of the pneumatic cylinder 8 runs into the switch and a command is given to reverse the rod 3 of the pneumatic cylinder 2. The lever 4 is rotated, the roller 6 is moved to the cavity of the cam 5, there is a rise

0 drive 7 with stamping elements 8 and the output pin 14 from the hole 13 of the limiter 12. The carriage 10 is unlocked and returns to its original position, where it abuts against the limiter 11, and the lever 4

5 turns the cam 5 and lowers the actuator 7 with the stamping elements 8 onto the cushions 22 in the bathtubs 21. This completes the operation of the device, the Step conveyor 27 delivers new parts 25 and the cycle repeats.
