Description

 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 a vibration exciter.

 The disadvantage of this device is the low productivity and quality of processing due to the presence of various zones of the dynamic impact of abrasive particles on the workpiece located in the container.

 Also known installation for vibration processing of parts containing a container, inside of which is located 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, the UVD-1 vibrating machine was selected, which contains an elastically mounted container and a crank-type vibration exciter.

 The disadvantage of this machine is its low technological capabilities due to the impact on the workpiece of a constant mass of the working medium.

 The purpose of the invention is the expansion of technological capabilities by changing the intensity of the impact of the working environment on the part during processing.

 This is achieved by the fact that in a vibrating machine containing an elastically mounted vibration platform with a container, guide columns and a vibration exciter, the vibration platform is made hollow with movable walls and with a central window over which the container is mounted without a bottom.

 The drawing shows the kinematic diagram of the machine.

 The vibrating machine consists of an elastically mounted vibration platform 1 with movable walls 2 (vibration exciter, guide columns and the mechanism for moving the walls are not shown), on which a container 3 without a bottom is mounted above the window. A device 4 is mounted on the side wall of the container 3 for fastening and rotating the workpiece 5. The working medium 6 is loaded into the volumes of the vibration platform 1 between the movable walls 2 and the container 3.

 The machine operates as follows.

 After starting the vibration exciter, the working medium 6 acquires a vertical alternating movement. With an increase in the processing intensity, the walls 2 are shifted to the edge of the window in the vibration platform 1 and the entire mass of the working medium acts on the part 5. Then, as the part rotates for those sections that require less intensive processing (for example, the edges), the walls 2 are shifted in the opposite direction and the working medium fills the vacant volume in the vibration platform without the possibility of free movement in the vertical direction. Thus, the reduced mass of the working medium 6 acts on the part 5, which leads to a decrease in the processing intensity.

 Technical advantages of the proposed technical solution over the prototype: a change in the mass of the working medium acting on the part during processing due to the movable walls is provided; Isolation of a part of the working medium due to the hollow vibrating platform has been achieved.
