Abstract

The invention relates to vibration processing of parts and can be used in various industries as a grinding machine. The machine has high productivity due to the preservation of the frequency of movement of the working medium 9 throughout the entire processing cycle. This is achieved by changing the gap between the working medium 9 and the lid 5 of the container 4. 1, which is consistent with the shape of the part.

The invention relates to vibration processing of parts with a free working medium and can be used in various industries as a grinding machine.

A device is known consisting of an elastically mounted container and vibration exciters.

The disadvantages of this device include the low productivity and quality of processing due to the presence of various zones of dynamic exposure of abrasive particles to the workpiece located in the container.

Also known is a machine for vibration processing of parts, comprising a container, inside of which there is a tedder with blades, a vibration exciter and an elastic suspension system,

The disadvantage of this installation is the low productivity due to the low efficiency of the agitator.

As a prototype, a vibrating machine containing an elastically mounted container and a vibration exciter is selected.

The disadvantages of this machine include low productivity due to the constant gap between the working medium and the container lid.

The purpose of the invention is to increase the productivity of the process by providing optimal design and technological parameters of the equipment during the entire processing cycle.

This is achieved by the fact that in a vibrating machine containing an elastically mounted platform with a vibration exciter and a container equipped with a movable cover connected to a crank mechanism introduced into the machine, there is a kinematic between the inserted shaft of the part rotational drive and the crank mechanism communication.

The drawing shows a kinematic diagram of the machine.

The vibrating machine consists of an elastically mounted platform 1 (vibration exciter and

guide columns are not shown) on which the electric drive 2 for rotating the workpiece 3 and the container 4 with the movable cover 5 connected to the crank 5 by the connecting rods 7 are mounted. The torque of the crank 6 is transmitted from the shaft of the electric drive 2 via a V-belt transmission 8, and processing of part 3 is carried out by the working medium 9.

0 Vibrating machine works as follows.

After starting the vibration exciter, the working medium 9 acquires a linear alternating movement. At the same time

5, the part 3 is rotated. Since the projection of the part 3 changes over a wide range during rotation, resulting in a violation of the periodicity of movement of the working medium 9, it is necessary

0 to adjust the gap between the medium and the cover in order to maintain periodicity of movement. The larger the projection area of the part, the smaller this gap should be due to the inhibition of the fluid flow by the part.

Thus, the kinematic coupling 8 together with the crank 6 and the connecting rods 7 provides a change in the gap according to the shape of the part.

0 Thus, an increase in the process productivity is achieved by maintaining the periodicity of the movement of the working medium in the closed volume of the container, which guarantees high dynamic characteristics of the medium.
