Description

The utility model relates to finishing and hardening of parts in containers and will find application in any field using vibration processing of parts by surface plastic deformation.

A device for processing parts is known (SU 1818206, B24B 31/067, publication 06/27/2016), in which removable elements are provided in the form of an arc, attached to radial rods, which, in turn, are located on the shaft in a container with abrasive material. Locks for fastening parts are fixed on the arc, located along a sinusoid to prevent overlapping of the hardening zone of the parts with each other.

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

A device for finishing parts that is closest to the claimed technical solution (No. GB 851388, B24B 31/06, publication of 10/19/1960), in which hardened or grinded parts are mounted on brackets mounted radially on a rotating shaft, is known. In this device, parts evenly undergo processing due to rotation and passage through the working medium.

However, the brackets in this device are not adapted for fastening parts of complex shapes or large masses. The length of the radial brackets is a critical parameter that determines the number of attached parts that do not overlap each other's processing 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 a fixed container size.

A technical problem that has not been solved in the known device, the solution of which is provided by the claimed invention, is to create a universal device with the possibility of high-quality processing of parts of various sizes and configurations.

The technical result consists in improving the quality of processing, expanding the technological capabilities of the vibrating machine, reducing the time for preparatory operations, reducing the complexity, reducing the time for processing a large batch of parts as a whole.

The technical result is achieved due to the fact that in a device for processing parts containing a vibrating platform with a container mounted on it, in which a shaft with an external drive and equipment is located in the bearing units, in accordance with the claimed utility model, the equipment is made in the form of a shaft mounted a disk with holes in which the lodgement and supports are fixed, as well as with the help of pins, a clamp consisting of two plates is fixed, the upper plate being made of metal and the lower one of non-metallic mate rial.

In addition, a central hole of square cross section is made in the disk, all openings being made at the end of the disk.

The use of equipment in the form of a disk fixed to the shaft with holes in which the lodgement and supports are fixed, as well as using clamps, a clamp consisting of metal and non-metal plates is fixed aimed at achieving a technical result: improving the processing quality, expanding the technological capabilities of the vibrating machine, reducing the time by preparatory operations, reduced labor intensity, reduced time for processing a large batch of parts as a whole.

A device for processing parts is illustrated by drawings:

in FIG. 3 - interchangeable disk for mounting large parts;

.

A device for processing parts is shown in FIG. 1. On the basis of 1, racks 2 with pneumatic shock absorbers 3 and racks 4 for hinged supports 5 for the vibration platform 6 are mounted 6. From above, on the platform 7 of the vibration platform 6, a container 8 with a working medium 9 is fixed.

On the basis of 1, under the vibration platform 6, an electric motor 10 and an eccentric vibration exciter 11 are installed.

The vibration platform 6 is mounted at one end on the uprights 4 by means of articulated supports 5, and at the other end it is supported on the uprights 2 with pneumatic shock absorbers 3. Thus, the vibration platform 6 is fixed with the possibility of angular oscillatory movement.

In the bearing assemblies 12, mounted on the walls of the container 8, a shaft 13 is placed (Fig. 2). On the shaft 13, rigging 14 for fastening the workpieces 15 is rigidly fixed, which consists of a removable disk 16 with fasteners 17, with which workpieces 15 are fixed (Fig. 1, 2). At the same time, a central hole 33 of a square section (Fig. 3) is provided in the disk 16, which corresponds to the square section of the seat on the shaft 13. The element for attaching the disk to the shaft includes a stop 18 mounted on the shaft 13, a square section made on the shaft 13, and a sleeve 19. Using the nut 20, through the threads made on the shaft 13 (not shown), the disk 16 and its fastening elements are fixed. An external drive 21 is connected to the shaft 13, which rotates around its own axis.

For fastening a group of large-sized parts 15 of complex shape, a removable disk 16 is provided, for example, of a metal sheet 10 mm thick., In the end of which holes are made, located in accordance with the configuration and shape of the part 15 (Fig. 3). During installation, the natural holes of the part 15 are used.

Oversized part 15 is mounted on the disk 16 using a fastener 17, consisting of a lodgement 23, a clamp 24, 2 studs 25 (Fig. 4, 5) and supports 26, in the form of a metal cylinder with gaskets 27 of non-metallic material, for example polyamide (Fig. 4). The holes 28 are intended for rigid fixation of the supports 26 (Fig. 3). Holes 29 are used to secure the lodgement 23. Studs 25 are fixed in the holes 30, fixing the clamp 24. The clamp 24 is made of two plates: a metal plate 31 and a non-metal 32 made, for example, of polyamide, which eliminates the contact of the part 15 with the metal plate 31 and improves the quality of processing.

A device for processing parts operates as follows.

A batch of workpieces 15 is fixed on the disk 16. The part 15 is mounted on the supports 26, and on the side it is held by a tool holder 23. Then a clamp 24 is mounted over the part 15, which is fixed with two studs 25. The use of the clamp 24 makes it possible to securely fix the part 15 on the disk 16, this studs 25 make it possible to adjust the height of the mount depending on the dimensions of the part 15.

The disk 16 is mounted on the shaft 13, which is then installed in the bearing assemblies 12 of the container 8. The working medium 9 is poured into the container 8. After starting the electric motor 10, the vibration platform 6 acquires angular vibrations α, which leads to the movement of the working medium 9. It should be noted that the vibration platform drive 6 may be performed in another known manner. In particular, the proposed snap design can also be applied in the case of unidirectional movement of the vibrating platform up and down.

At the same time, an external drive 21 of the shaft 13 is launched, which leads to the rotation of the disk 16, as a result of which the position of the parts 15 in the container 8 is constantly changed, the surface of the parts 15 interacts with the working medium 9 at different angles and, as a result, the efficiency and uniformity of the finish increase - hardening processing.

For parts of complex shapes (for example, a bracket, hook, etc.), the technological process prescribes a change in the position of the parts 15 for surface treatment of the parts in accordance with the requirement of design documentation. To do this, stop the processing process, open the lid of the container, change the position of the parts 15 in the upper part of the disk 16 without dismantling the equipment and unloading the working medium 9. Then the processing of the surfaces of the parts 15 in a different position continues.

If there are several disks 16 for various parts 15, it is possible to mount other batches of parts 15 of different nomenclature on the corresponding disks 6 simultaneously with processing on the machine of the previous batch. At the end of processing a batch of parts 15, the disk 16 is replaced and the processing of a new batch is started without a complete unloading of the working medium 9.

Thus, the use of removable disks 16 can reduce the total time for preparatory operations and reduce the overall complexity of processing parts 15. Using the device for processing parts as a whole, as well as the use of the claimed fastener, allows you to achieve the required surface quality, microhardness, residual compressive stresses in the surface a layer of parts, which corresponds to paragraph 4.6 of the instruction PI 1.4.2188-2005 developed by the National Institute of Aviation Technologies OJSC.
