The purpose of the invention is the expansion of technological capabilities by coating in automatic mode at various lengths, improving the performance and reliability of the device. This is achieved by the fact that in a device comprising a housing 1, a shank 3, pushers 11, bushings 15, rubbing rods 14 and a loading mechanism, the latter is made in the form of a pneumatic cylinder with a single-acting coupling 4, a piston 5 with an adjusting bolt 6, a spherical stop 7, distribution disc 8 with a spherical recess, three pairs of rocker arms 10 and rods 2 with spherical tips, return springs 13 and feed limiter 17, while the body is made in the form of a cylinder. 3 il.

Description

The invention relates to the coating of a friction-mechanical method and can be used for coating a mirror cylinder liner.

The purpose of the invention is the expansion of technological capabilities by coating in automatic mode at various lengths, improving the performance and reliability of the device.

Figure 1 shows the device, a general view; in FIG. 2, the same view from the side of the processing elements; FIG. 3 is a diagram of the connection of the device to the air line.

The device consists of a body I, which plays the role of a cylinder in a loading mechanism, made in the form of a cylinder, to which it fastens a cover 2 with a stem 3, in the cover there are channels for air supply. The shank is rotatably mounted relative to the tailpiece. The coupling 4 is unilateral. Inside the housing there is a piston 5, in which an adjusting bolt 6 is installed along the axis with a spherical stop 7. Inside the housing there is a distribution disk 8 having a spherical recess in the center, which includes a spherical stop. From the side

opposite to the shank, on the body, three rocker arms 10 are mounted on axles 9, rocker arms are pressed to the thrusters with one shoulder, the other arms - to the gatokes with a spherical tip 12. Shoulders of the balancer arms connected with the rods are tucked in return springs 13. The thrusters together with rubbing rods 14 placed in sleeves 15 installed in the housing. The rubbing rods are in contact with the pushers and the workpiece 16. On the part of the part in the case, a feed limiter 17 is installed. The device is connected to the air line through air line 18 Anom 19, pressure reducing valve 20 and pressure gauge 21.

The device works as follows

The shank of the device is installed in the spindle of the drilling, boring or quill tailstock lathe, after which the device is brought into rotation (in the case of installation on a lathe, the part rotates), then the valve 19 is supplied with air through the air line 18 and unidirectional coupling 4 into the cavity of the cylinder body. The adjustment and control of the air pressure is carried out by means of a pressure reducing valve of a 10 l pressure gauge 21.

Under the action of air pressure, the piston 5 begins to communicate and the spherical support 7 presses on the distribution disk 8. The distance between the distribution disk 8 and the piston 5 is adjusted by means of an adjusting bolt 6. The distribution disk presses on three rods 12 each rod presses on the horizontal shoulder his rocker 10,

The rocker arms 10, turning on, axis x 9, with their other shoulder, press on the pushers 11, which transfer pressure to the rubbing bars 14g

The rubbing rods 14, moving under pressure relative to the surface of the part 16, previously wetted with a working fluid, produce a coating. The number of rods, rocker arms and rubbing rods,

equal to three, provide a constant contact with the self-installation of all rods with the distribution disc and a more favorable distribution of forces on the surface of the part compared to the prototype.

To limit the movement of the piston and distribution disc, in order to prevent the yokes from breaking, the feed restrictor 17 serves. The return springs 13 serve to ensure the constant contact of the rocker arms with the rods and to return these parts to their original position to replace the rubbing rods when they are fully worn.

After finishing the treatment, the air valve 19 is depressurized and the device is removed from the part. When the end stops interacting with the crane are set in the course of moving the device, the device operates in automatic rezhikg,

Compared with the prior art, the proposed device allows a 1.6-fold reduction in the complexity of coating by increasing the number of rubbing rods and increasing the reliability of the device.
