Description

The invention relates to devices for volumetric vibration treatment, in particular, industrial vibration systems widely used in the industry, designed to vibro-encrypt parts with a free abrasive, where the process: vibro-processing is driven by vibrating the working chamber of the bunker with its parts and abrasive material, and can be used in various industries.

A known apparatus for volumetric vibration treatment of parts in a V-shaped container, inside of which there is a agitator with blades C1, passing through the opposite walls of the container.

A disadvantage of the known installation is the processing time.

The aim of the invention is to intensify the machining process and to ensure the machining process of parts for one turn of the agitator.

The goal is achieved due to the fact that parts with abrasives are placed between two blades of a rotator installed rotatably around its own axis, forming separate volumes in the working volume of the container, and a brake device is installed on your agitator, which regulates the speed of rotation of the agitator.

Figure 1 presents the proposed installation, the overall look; Fig. 2 shows a device 10 regulating the rotation speed of the agitator; FIG. 3 shows the trajectories of the movement of the mass of abrasive and parts in the working container.

It includes a brake disc b, fastened on the axis 3 of the agitator, and a brake pad 7 interacting with it, which by means of a force-adjustable spring 8 is pressed against the inertial wedge 9, which has

The installation operates as follows. The mass of abrasive and Parts located in container 1 by means of the impact on it of the source of vibrations is moved in the container along a trajectory close to the V-shaped forming wall of the container. At the same time, the mass of abrasive and parts presses on the blade of the agitator, moving it around the axis. Moreover, the angular speed of movement of the blade, determined by the speed adjustment mechanism, will be slightly lower than the speed of movement of individual parts and abrasive grains, as a result of which they will receive additional movement in the volume between the two blades. The cumulative (taking into account this movement and the angular movement of the blades themselves) will be a petal movement trajectory. - The rotation speed of the agitator is slowed down by periodically affecting the brake pad 7 on the disc 6. The pad 7 is moved when the container moves to the right (in fig. Down) due to the interaction with the inertial wedge 9, the inertia force of which is sufficient to overcome the force of the spring 8. Clamping force and, consequently, the decelerating force of the agitator is controlled by the force of the spring 8. With an increase in the deceleration of the agitator, the proportion of the additional movement of the abrasive and parts in the volume between the two blades increases. By setting the braking to a size that is sufficient for the part to be fully machined in one turn of the agitator, the process is also continuous (parts are unloaded from one cavity between the blades of the agitator while others are loaded and processed). The intensification of the vibration treatment process in the device of the proposed construction thus occurs due to the additional movement of parts in the volumes between the two blades with the formation of a lobe path of motion. This makes it possible to reduce the labor intensity of the vibration treatment of parts by 1.5–2 times and makes it possible to automate the process. An apparatus for volumetric vibration treatment of parts in a V-shaped container, inside of which is an agitator with blades passing through opposite racks of the container, which differs in that, in order to intensify the vibratory processing process, the agitator is rotatably mounted around its own axis , and its blades are made with the possibility of dividing the working volume of the container into several smaller volumes, while the installation is equipped with a braking device mounted , on the drive shaft of the agitator.
