Description

The invention relates to the processing of parts with a granular working medium and can be used in the finishing and hardening of large parts with their fixation in vibrating containers,

A device for vibration treatment is known, which comprises an operating unit elastically mounted on the base with a source of oscillations, while the operating unit is composed of a working capacity elastically connected to each other and a reactive mass with a fixture rigidly attached thereto for mounting the workpieces 1.

A disadvantage of the known device is high energy consumption, due to the use of an electromagnetic vibrator as a source of vibrations, and as an elastic connection between the active and reactive masses - elastic metal rods.

The purpose of the invention is to reduce the power consumption of the device.

The goal is achieved by the fact that in a device for vibration processing, containing an elastically mounted on the basis of the working body with a source of oscillations, the working body is composed of a working capacity elastically connected to each other and a reactive mass with a fixed fixture on it, the reactive mass is made in the form of a cylindrical shell enclosing the working capacitance, mounted on the base with the help of an elastic teapot suspension, with the source of oscillations It is complete in the form of a system of two eccentric vibrators with elastic rods mounted on a cylindrical shell on either side of its vertical axis with an inclination relative to the latter, and the ends of the rods are attached to the working capacity.

FIG. 1 schematically shows the device, a general view; in fig. 2 - the same, side view.

The working tank 1 (Figs. 1 and 2) with the help of elastic elements consisting of shock absorbers 2 and buffers 3 is suspended in a cylindrical shell 4. A oscillation source is attached to the cylindrical shell and is a box 5 in which the engine 6 is fixed , connected by a chain transmission 7 with the shafts 8. The shafts 8 are installed in the supports 9 of the box. Eccentrics 10 are fastened on the shafts, which are connected to tank 1 by means of elastic rods 11. The angle between the action planes of the rods 11 is 90 °.

Hydraulic cylinders 12 with brushes 13 are securely attached to the ends of the shell 4. Consoles 14 are fastened to the console. Rods 15 with grippers 16 are inserted in the console to hold the part 17 during machining. Shell 4 with a source of vibrations and an elastically fixed container 1 ( the working body) with the help of elastic timbers 18 is introduced to the posts 19 of the base.

The device works as follows.

The rotation from the shaft of the electric motor 6 is transmitted through the chain transmission 7 to the shafts 8 with eccentrics 10. The eccentrics attach alternating vibrations to the connecting rods 11, which through the elastic elements of nonlinear stiffness excite the capacitance of capacitance 1. Each rod excites the oscillation of capacitance in its plane. As a result of the addition of two displacements made at an angle of 90 ° and a change in the phase angle between the eccentrics of the container, oscillations along a trajectory of various shapes can be given. By adjusting the gap between the stops of the buffers 3, you can change the magnitude of the amplitude of the capacitance oscillations.

Item 17 is secured in the jaws 16 of the fixture, which is rigidly mounted on the shell. Thus, the part oscillates with the shell in antiphase with oscillations of the working capacity. The fixture is introduced and removed from the working tank by means of hydraulic cylinders 12.

B of the proposed design, the power link between the source of oscillations and the working capacity is mechanical, elastic, non-linear, which allows the device to operate stably in resonant modes, and this in turn makes it possible to save energy source of oscillations 4-5 times. When the device is operating in the resonant mode, power consumption is necessary only to replenish the internal losses in the elastic elements of the suspension, and the drive.
