Abstract

FIELD: process engineering.

SUBSTANCE: invention relates to machine building and can be used for vibromechanical treatment of parts with free filler by surface plastic deformation. This machine comprises motor, bed, props, vibroexciter and vibroplatform arranged at props to support the container with working fluid and processed part. One end of said vibroplatform is secured at posts by pivoted mounts. Opposite end of said platform rests on props with pneumatic dampers secured at said bed to perform angular oscillatory displacement to make working fluid in container perform elliptical motion. Said vibroexciter is composed of two-way crank gear with cams arranged in symmetry on common shaft and articulated via V-belt drives with the motor shaft both working ends while con-rods are articulated with vibroplatform.

Description

The invention relates to vibration processing of parts with a free filler (polished balls, granules, abrasives) by methods of surface plastic deformation and can be used in machines for finishing and hardening of parts.

A device (type Installation for Vibro-processing Parts UVD-3 or UVD-1) for vibration processing of parts, consisting of a vibrating plate mounted on pneumatic shock absorbers. Two guide racks are attached to the bottom of the plate, limiting its movement in the longitudinal and transverse directions. A container with a component and a working medium fixed in it is installed on the stove.

Also known is a vibration machine closest to the claimed technical solution (Patent RU No. 20099840; B24B 31/06, publication March 30, 1994) containing a container with a workpiece and a working medium mounted on a vibrating platform driven by vibration exciter. The vibrating platform is connected to the base by means of an elastic connection, and the end of the vibrating platform through the hinge element is mounted on a vertical guide rack with the possibility of reciprocating movement. The vibrating platform relative to the rack is mounted cantilever.

The disadvantage of this device is the destruction of the guide rack due to variable loads during reciprocating movements of the hinge element. The interaction of the working environment with the part does not provide sufficiently effective processing of the part due to the small component of the horizontal movement of the working environment.

The technical task of the invention is to increase the reliability of the vibrating machine and increase its service life, as well as increasing the efficiency of interaction of the working environment with the workpiece.

The technical result is achieved by the fact that in a vibrating machine for finishing and hardening processing of parts containing an electric motor, base, racks, vibration exciter and a vibration platform mounted on racks, on which a container with a working medium and a workpiece is fixed, according to the claimed invention, one end platform is mounted on two racks by means of hinged supports, and the other end under the container mounting point rests on racks with pneumatic shock absorbers mounted on the base, with angular vibrational movement to bring the working medium in the container to elliptical motion, while the vibration exciter is made in the form of a double-sided crank mechanism, the eccentrics of which are located symmetrically on the common shaft and are connected via V-belt drives with two working ends of the motor shaft, and the connecting rods are pivotally connected to vibration platform.

The device of the vibrating machine is illustrated by drawings, where in the neutral position are shown:

in FIG. 1 is a side view of a vibrating machine for finishing and hardening processing of parts;

in FIG. 2 - section aa.

A vibrating machine for finishing and hardening processing of parts is shown in FIG. 1, where, on the base 1, racks 2 with pneumatic shock absorbers 3 and two racks 4 for hinged supports are mounted 5. A container 8 is fixed on top of the platform 6 of the vibration platform 7.

The electric motor 9 drives the vibrating platform 7 with the help of eccentrics 10 symmetrically mounted at both ends on a common shaft 11 (Fig. 2). The crank mechanisms 12 are connected to the electric motor 9 through V-belt drives 13 and through the connecting rods 14 interact with the vibroplatform 7.

After starting the electric motor 9, the vibration platform 7 acquires angular oscillations α. The movement of the working medium 14 in the container 8 will have horizontal and vertical components. This movement of the working medium 14 allows to intensify the process of processing parts 15, mounted in the container 8.

The supply of compressed air to the cylinders of pneumatic shock absorbers 3 is carried out from the pneumatic manifold 16 through the pipe 17.

The proposed design of the vibrating machine eliminates the vertical movement of the hinge element along the vertical guide rack. This reduces the harmful effects of loads on the structure, increases the service life of the machine, and also increases its reliability. The angular movement of the vibrating platform leads to an elliptical movement of the working medium in the container, in which the processing of parts is intensified.
