Description

The utility model relates to the machine-building, instrument-making industry and stone processing, in particular to vibration processing of parts.

Known devices for vibration treatment of parts as a source of vibrations in which unbalanced vibrators are used (SU No. 952544, IPC В24В 31/06, published on 08/23/1982; SU No. 956251, IPC В24В 31/06, published on 09/07/1982; SU No. 323254, IPC В24В 31/067, published 01.01.1972). These devices have one or more working chambers (containers) connected in series.

The disadvantage of the known designs is that the machines have a "connected" amplitude-frequency characteristic, i. E. changing the frequency automatically leads to a change in the amplitude of the oscillations. This narrows the technological possibilities of controlling the processing process, and, moreover, drops out of consideration of the range of potentially highly efficient vibration modes. For example, at high speeds of rotation of imbalances, the value of the amplitude is minimal, therefore, the processing performance is low.

In addition, due to the absence of a stationary container, the installation of auxiliary technological equipment (for example, a device for feeding and separating abrasive and parts) is complicated.

A device for vibration processing of parts is known (SU No. 1430239, IPC В24В 31/073, published on 10/15/1988), containing an annular container with a bottom made of elastic material and a vibrator made in the form of a vertical shaft mounted on the base with a rotation drive and a group of radially located rollers rolling around an elastic container bottom. The device is equipped with a mechanism for reciprocating the inner wall of the container by means of a screw pair. Fluctuations in the working medium are transmitted to the container from the elastic bottom, rolled by rollers.

A common feature of the claimed utility model with the aforementioned device is the presence of an annular container with a bottom made of elastic material.

The disadvantage of this device is the presence of one vibrator, which creates only vertical vibrations in the mass of the load, which does not allow for sufficiently efficient processing of parts.

The closest in technical essence and adopted as a prototype is a device for vibration processing (RU No. 2268133, IPC В24В 31/073, published on 20.01.2006), containing an annular container with outer and inner walls and a bottom made of elastic material. The outer wall is rigidly fixed to the base. The inner wall with the help of a vibrator is movably mounted with the possibility of reciprocating movement in the vertical direction and reciprocating rotational vibration around its axis. The outer and inner walls in the upper part of the device are interconnected by elastic elements located evenly at an angle to the radial direction in one direction. This design expands the ability to control parameters and control the nature of vibrations and increases the uniformity of processing parts in the working area. However, the presence of one vibrator does not allow efficiently enough, with high productivity to process parts of different names requiring different processing modes. This narrows down the technological possibilities of the processing process.

The general features of the claimed utility model with a prototype are the presence of an annular container, as well as the implementation of the bottom and walls of the container from an elastic material.

The disadvantage of the prototype is the presence of one vibrator, which creates oscillations in the mass of the load, which does not allow sufficiently efficient and productive processing of parts in intensive modes of equipment operation. In addition, it is not very convenient to regulate the vibration amplitude in the installation, because the adjustable link is located inside the installation. Therefore, it is necessary to stop processing in order to make adjustments (increase or decrease in the amplitude of oscillations).

The problem to be solved by the claimed utility model is to create a high-performance device that allows processing a greater number of parts per unit of time and performing intensive processing operations on parts. And also improve the quality of processing.

The technical result of the claimed utility model is to increase productivity and expand the technological capabilities of the device for processing.

The technical result is achieved in that the device for vibration treatment containing an annular container with outer and inner walls and a bottom made of elastic material. The outer wall is rigidly fixed to the base. The inner wall with the help of a vibrator is movably mounted with the possibility of reciprocating movement in the vertical direction and reciprocating rotational vibration around its axis. The outer and inner walls in the upper part of the device are interconnected by elastic elements located evenly at an angle to the radial direction in one direction. The vibrator is made in the form of a crank mechanism acting on the inner wall of the container according to the utility model, additionally contains three more vibrators consisting of crank mechanisms located at an acute angle to each other acting on the elastic bottom of the container from the side, that is, on the inner and outer walls of the container ... This allows the loading flows to be directed from the inner and outer walls of the container towards each other at an acute angle and to ensure the collision of the parts. Four crank mechanisms are driven from a bent shaft consisting of shafts connected by flexible shafts. The upper part of the annular container is made of steel by one third of the height of the inner and outer walls. The metal walls are immovable and rigidly fixed to the vibration unit, and are reinforced and connected to each other by four metal bridges. A cover is installed on the upper part of the container, which has four radially located openings for fluid supply. The liquid is fed into the container through four pipes with taps. A closed liquid circulation system is used, including a settling tank with an electric pump installed in its upper part. This provides an improvement in the quality of processing of parts, a decrease in surface roughness due to the removal of processing products from the working area of the container. In contrast to the prototype, the amplitude of oscillations in the container is regulated by means of vertical reciprocating movement of the entire container due to four screw pairs at right angles to each other and located along the perimeter of the vibration installation.

Due to lateral and bottom impulse influences on the contents of the container, a more intensive volumetric processing is carried out, the frictional forces in the loading and impact interactions increase, allowing more efficient processing. To intensify the process, the container is installed on four springs evenly distributed around the perimeter.

The presence of distinctive features allows us to conclude that the claimed utility model meets the “novelty” condition of patentability.

The claimed device is illustrated by drawings, where figure 1 shows a general view of the claimed device, and figure 2 is a top view.

The device for vibration treatment contains: a frame 1 of the body, in which an annular container 2 with a bottom and walls of elastic material is installed, vibrators 3 representing crank mechanisms driven from a curved shaft consisting of flexible shafts 4 and shafts 5, a V-belt transmission 6, an electric motor 7. The container is installed on the frame 1 with the fastening bolts 8 on the springs 9. The amplitude of the container oscillations is adjusted by screwing (unscrewing) four bolts 8. In the upper part of the container there is a cover 10 with four holes for fluid supply. The liquid is supplied from the settling tank 11 by means of an electric pump 12 to a system of four taps 13 through the supply hose 14. After processing, the liquid is drained through the drain hose 15 back to the settling tank, therefore, there is a closed liquid circulation in the installation. Shaft bearing - 16.

The device works as follows. From the electric motor 7 through the V-belt transmission 6, the rotation is transmitted to the bent shaft located in the bearings 16, and from it to the crank mechanisms 3. Which create reciprocating vibrations in the elastic bottom of the container 2. And from it, the vibrations are transmitted to the loading of the container, consisting of workpieces and abrasive (not shown in the figures). Processing is in progress. During which the processing liquid is supplied to the container 2 through the distribution system, from the settling tank 11 with the help of the electric pump 12 through the supply hose 14 to a system of four taps 13 into the container 2. The liquid is drained with the processed products back into the settling tank 11 through the drain hose 15 This is how the closed circulation of the liquid is carried out in the installation.
