54) SETTING FOR VIBRATION TREATMENT

P

The invention relates to the vibration treatment of a part and can be used for processing fixing parts with narrow channels in vibrating containers.

A known device for vibrating processing of parts with fastening in a vertical position in a receiving oscillation from vibrators and a container loaded with working medium, containing a closed, without a shutter in the bottom of the container, a system for feeding and unloading working medium with a storage capacity and a lifting mechanism for working medium li.

The disadvantage of this installation is the lack of conditions for the late flow of the controlled flow through the container, which is not, provides high-quality processing of details with narrow channels.

The aim of the invention is to improve the quality of processing parts with narrow channels by creating a directional flow of the working medium from the container.

To do this, the container is equipped with a replaceable bottom with grooves made according to the flow areas of the machined parts, and in a closed system of supplying the working medium, a valve is installed at the outlet of the container that controls the level of the working medium in the container. In the process of moving the working medium through the container, the grooves located in its replaceable bottom organize a directed flow of the working medium through the channels of the parts.

Mounting parts

10 is produced on bearing bearings mounted on the bottom of the container that allow the parts to turn; c from the action of displacement of working media.

FIG. 1 is a longitudinal section of the proposed installation; in fig. Figure 2 is a top view of the installation with the container lid removed and conditionally removed in one piece; in fig. 3 is a diagram of the movement of the working environment and the decomposition of the force of gravity into components.

The installation contains a welded box 1, inside of which is mounted on rubber shock absorbers 2, etc.

Claims (1)

25 container 3. Four gear vibrators 4 (one on the X axis, one on the Z axis and two on the Y axis) are attached to the container 3, which are driven in rotation from the motor 5 of stationary current by the transmission system (not shown), container 3 and bearing supports b install parts 7 and fill the working medium 8. In the replaceable bottom 9 of the container 3 there are an empty slot 10, through which the working medium 8 passes and then through the spring-loaded valve 11 installed in the outlet 12, along an inclined chute 13 into the container 14. From the container 14 working medium in revisions; a bucket conveyor 15, which is set in motion from drive 16, into container 3 via nozzle 17 through opening 18.; A tensioning device 19 is available for precise amplitude adjustment. The installation operates as follows. By switching on the direct current motor 5 through the transmission system, the gear vibrators 4 begin to rotate and vibrate the contour 3 to which they are attached. Parts are located in the container. 7 AT bearing supports b. : By turning on the drive 16, the bucket conveyor .15, which captures the working media 8 (balls and abrasive slurry), is placed and fed into the container 3, at this time. m spring-loaded valve 11 is closed. As soon as the level of the working media reaches a certain mass, on which the spring-loaded kl 11 pan is adjusted, it opens and the working medium moves along the chute 13: into the hopper 14. The device uses the effect in detail. With the vertical placement of parts on the bearings, the rotation is carried out by using the effect of movement on an inclined surface, which occurs when the working media moves along the inter-blade channels. An explanation of the effect is given in FIG. 4, which shows the decomposition of forces arising from the downward movement of the working mass. The resultant force E creates a torque. An apparatus for vibratory processing of parts with fastening in a vertical position in a receiving oscillation from vibrators and a container loaded with working medium, comprising a closed supply system of working medium with a storage capacity and a mechanism for lifting the working medium, so that , in order to improve the quality of surface treatment of parts with narrow channels by creating a directional flow of working medium from the container, the latter is provided with a replaceable bottom with grooves made accordingly; The location of the boreholes of the parts being machined is in place, and in a closed system of supplying the working medium, a valve introduced into the installation is installed at the outlet of the container, which controls the level of the working medium in the container.
