Description

This invention relates to metalworking and can be used in the finishing treatment with a free abrasive.

 Installations for centrifugal abrasive machining of parts in containers are known, consisting of a planetary gear and containers installed in a carrier having a horizontal axis of rotation and performing a planetary motion. Moreover, the carrier is made in the form of a rotor, and the containers are installed rotatably relative to the axis of the rotor at an adjustable angle to the axis of its rotation. Ll The disadvantage of this installation is that the forces acting on the parts are variable in magnitude. The magnitude of the force acting on each particle in the container depends on the position of the container relative to the carrier.

The aim of the invention is to improve the processing performance during polishing.

This goal is achieved by the fact that the installation is equipped with guide rings mounted parallel to the plane of rotation of the carrier, sliders.

in which the axes of the connectors are mounted, and the rollers mounted on the axes of the containers with the possibility of contact with the inner surface of the rings, while in the carrier there are radial grooves in which spring-loaded sliders are placed. The axis of the guide rings is offset relative to the axis of rotation — the carrier is measured by the value

g "j

h

where g is the acceleration of free fall,

OPC - carrier speed.

FIG. Figure 1 shows the kinematic scheme of the installation; figure 2 shows a diagram of the interaction of the rollers with guide rings.

The apparatus comprises a carrier 1 fixed rigidly on a shaft 2, which waddles in bearing supports 3.

The pilots made radial grooves 4, in which the sliders 5, which were loaded by springs 6, are placed.

At both ends of the shaft 7, guide rollers 10 are installed, interacting with the inner surface of the guide rings 11. The torque on the carrier shaft 2 is transmitted from drive 12 via chain drive 13, 14. Rotation to drive sprockets 9 of containers 8 is transmitted from drive 15 through sprockets 16-19, chain drive. The guide rings are installed with an eccentricity relative to the axle of rotation of the carrier 2.

, Installation works as follows.

When the drive 15 is turned on, the rotation through the sprockets 16-19, 9 of the chain transmission is transmitted to the shafts 7 of the containers. At the same time they are. begin to rotate around their own, making a relative movement with speed

When turning on the drive 12 rotation

through the transmission 13, 14 is transferred to the shaft 2 of the carrier 1. Rotating, the carrier 1. fascinates. sliders with 7 rollers of containers 8 installed in them. Thus, the containers will rotate with the planet carrier around axis 2, making a portable movement. Under the action of the springs 6, the slides 5 are pressed from the center of the carrier until the guide rollers 10 interact with the guide rings 11. AS BELOW the axis of the rings 11 is offset relative to the axis of the carrier 1, then when the carrier rotates, the distance from axis 2 to axis 7 containers 8 will be changed by law

where is the distance from axis 2 to axis 7

containers 8; R is the radius of the ring; e is the eccentricity of the ring relative to the carrier, (SJy, is the rotational speed of the carrier,

t is time;

 container radius. The application of the proposed installation allows us to substantially improve the quality of finishing (for example, polishing) by stabilizing the forces acting on the working environment, while simultaneously increasing the production of the treatment, since there is no processing where there is no processing.
