Description

The invention relates to finishing and hardening processing of parts in containers and will be used in any area that uses vibration processing of parts by the method of surface plastic deformation.

A device for machining parts (SU 1818206, В24В 31/067, publication 05/30/1993) is known, in which removable elements are provided in the form of an arc attached to the radial rods, which in turn are located on the shaft in a container with an abrasive material. Locks are fixed on the arc for fastening parts located along a sine wave to prevent the parts from hardening overlapping each other.

However, the arc is a structurally complex element for production, since the uniform distribution of locks along a sinusoid on the arc requires sufficiently accurate calculations and markings during manufacture. Also, locks for fastening parts have certain limitations in size, shape and weight of parts that can be fixed in them.

A device for trimming parts is closest to the claimed technical solution (no. GB 851388, ВBB 31/06, publication 10/19/1960), in which reinforced or ground parts are mounted on brackets mounted radially on a rotating shaft. In this device, parts are uniformly processed, due to the rotation and passage through the working environment.

However, the brackets in this device are not designed for mounting parts of complex shapes or large masses. The length of the radial arms is a critical parameter that determines the number of attached parts that do not overlap each other's machining zones. This requires an increase in the dimensions of the container when installing a large number of parts, or to reduce the number of simultaneously processed parts with fixed container sizes.

A technical problem that is not solved in a known device, the solution of which is provided by the claimed invention, is to create a universal device with the ability to process parts of various sizes and configurations.

The technical result consists in expanding the technological capabilities of a vibrobank, reducing the time for preparatory operations, reducing labor intensity, reducing the time for processing a large batch of parts in general.

The technical result is achieved due to the fact that in the device for processing parts containing a vibrating platform with a container in which a shaft with an external drive and equipment is placed in the bearing units, in accordance with the claimed utility model, the equipment is made in the form of a disk with holes mounted on the shaft equidistant from its center, while in the holes are mounted fasteners consisting of a lodgement and sleeves, which are fixed on the disk with a pin.

Placing a shaft in the container with a snap-in, which is made in the form of a disk with holes in which fasteners are mounted, consisting of a lodgement and bushings and fixed to the disk with a pin, is aimed at expanding the technological capabilities of the vibrating machine, reducing the time for preparatory operations, reducing labor intensity, reduction of time for processing a large batch of parts in general.

A device for processing parts is illustrated by drawings, which depict:

in fig. 1 - a device for processing parts, front view;

in fig. 2 is a device for machining parts, section A-A of FIG. one;

in fig. 3 - a removable disk for fastening small parts;

in fig. 4 — fastener for fastening small parts, section BB, FIG. 3;

On the elastic vibroplatform 1, a container 2 is installed in which the shaft 3 is fixed in the bearing assemblies 4 (Fig. 1). On the shaft 3 fix the snap-in 5, which consists of a removable disk 6 with fasteners 7, with which the workpiece 9 is fixed (Fig. 1, 2). To the shaft 3 is connected external drive 8, carrying out its rotation around its own axis.

There are several modifications of removable disks 6 for fastening various types of parts 9 (Fig. 3, 4).

For fastening a group of small parts 9, a removable disk 6 with holes 10 equidistant from the center is provided for fixing fasteners 7 (FIG. 3).

Part 9 is mounted on the disk 6 by means of a fastener 7 consisting of a cradle 11 and a sleeve 12, which create the necessary clearance and protect the part 9 from contact with the disk 6. The fastener 7 with part 9 is fixed on the disk 6 using studs 13 (Fig . four).

The device for processing parts works as follows.

On the disk 6, a batch of machined parts 9 is fixed. The disk 6 is mounted on the shaft 3, which is then installed in the bearing units 4 of the container 2. The working medium 15 is filled into the container 2. After starting the drive, the vibrating machine (not shown) vibrates, to the movement of the working environment 15.

At the same time, the external drive 8 of the shaft 3 is started, which causes the disk 6 to rotate, as a result, the position of the parts 9 in the container 2 constantly changes, the surface of the parts 9 interacts with the working medium 15 at different angles and, consequently, improves the efficiency and uniformity of the finishing -hardening processing.

For parts of complex shapes (for example, bracket, hook, etc.), the technological process prescribes a change in the position of parts 9 for surface treatment of parts according to the requirements of the design documentation. To do this, stop the process, open the lid of the container, change the position of the parts 9 in the upper part of the disk 6 without dismantling the equipment and unloading the working medium 15. Then the surface treatment of the parts 9 in a different position continues.

If there are several disks 6 for different parts 9, it is possible to mount other lots of parts 9 of different nomenclature on the corresponding disks 6 simultaneously with the machining of the previous batch.

At the end of processing the batch of parts 9 replace the disk 6 and begin processing the new batch without completely unloading the working environment 15.

Thus, the use of removable disks 6 reduces the total time for preparatory operations and reduces the complexity. It also reduces the time for processing a large batch of parts 9 as a whole.
