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.

Known vibration machine (patent SU 1404294, B24B 31/06, publication 06/23/1988), in which to exclude contact of the moving parts of the container interacting with the elastic support when operating in resonant mode, a support is provided in the form of a spiral spring, which is located inside cups. The cavity of the support is filled with a magnetic fluid that changes viscosity until it hardens, which leads to a decrease in the amplitude of the oscillation to zero under the influence of a magnetic field. Thus, it becomes possible to widely control the amplitude of the oscillations of the working chamber. At the same time, for the smooth operation of the device requires forced cooling of the liquid, which generally complicates the design and reduces manufacturability.

Known vibration machine (patent SU 861030, B24B 31/06, publication 09/07/1981), which consists of an elastically mounted container and a vibrator. A load is installed on the side of the container on a horizontal bar, which can be moved along the bar and fixed in a certain position using a latch. Thus, it is possible to adjust the horizontal displacement of the vibration center, thereby adjusting the amplitude of the vertical vibrations of the container.

A device for vibroimpact processing of parts is known (patent RU No. 122937; B24B 39/00, publication April 27, 2009), which contains a ball-filled working chamber with a vibrodrive, a shaft for turning the workpiece, and a rotation mechanism in the form of an overrunning clutch, as well as a lever and bracket connected to the vibrator. The lever disk enters with a gap in the groove of the bracket cassette with the ability to rely on the support point of the disk located on the lever and rotate the shaft during oscillation, which is accompanied by increased noise.

Known devices either create additional noise during operation, or are difficult to control the amplitude of the oscillation of the lever.

A technical problem that has not been solved in known devices, the solution of which is provided by the claimed utility model, is to reduce the noise of a working device; simplification of machine settings and regulation of modes; expanding technological capabilities.

The technical result is achieved due to the fact that in the device for finishing and hardening processing of parts containing a vibrating platform with a container in which a lever with a shaft is fixed to the bracket, the lever at one end is provided with a clip with an overrunning clutch located inside it, in accordance with a useful model, - a disk is installed on the outer end of the lever, and the bracket consists of two forks holding two glasses, inside which a rod is fixed, entwined with springs, while the glasses are threaded.

In addition, one glass is provided with an internal thread, and the second with an external thread.

The use of an arm, which consists of two forks holding two glasses, inside which a rod is fixed, entwined with springs, is aimed at reducing noise, because the springs do not allow the rod to hit the cup body. By screwing one cup into another by means of a thread, the springs can be fixed in different positions, this makes it possible to adjust the stiffness of the springs, which allows changing the swing amplitude of the lever and, as a consequence, the speed of rotation of the part on the shaft, depending on the installed disks.

Placing a removable disk on the outer end of the lever simplifies the adjustment of modes and the setup process, and also extends the technological capabilities of the vibrating machine, as the device can handle a wider range of different parts.

A device for finishing and hardening processing of parts is illustrated by drawings, which show:

in FIG. 1 - device for finishing and hardening processing of parts, side view;

in FIG. 2 - device for finishing and hardening processing of parts, top view, view A of FIG. one,

in FIG. 3 - bracket, side view.

A device for finishing and hardening processing of parts comprises a container 1 on a vibration platform 2, a lever 3 at one end of which has a thread for installing a weighting removable disk 4, a shaft 5 with a part 6, mounted in the bearing units 7 (Fig. 1, 2). The lever 3 is connected to the base of the container 1 by means of a height-adjustable bracket 8, and on the other hand is provided with a cage 9, inside which there is an overrunning clutch 10, mounted on the shaft 11. The bracket 8 consists of forks 12 and 13, holding cups 14 and 15, inside which is fixed to the rod 16, entwined with springs 17 and 18 (Fig. 3). The glasses 14 and 15 are provided with internal and external threads, respectively, for regulating their position relative to each other. A nut 20 is provided for fixing the position of the glasses. An indicator 20 is installed on the outside of the container 1.

The device operates as follows. Pre-carry out the adjustment of modes and adjustment of the vibrating machine. Moving the disk 4 along the thread of the lever 3, you can change the force on the lever 3 to give more torque to the rotation of the part 6.

The height adjustment of the bracket 8 is carried out by screwing or unscrewing the cups 14 and 15. This allows you to change the force on the springs 17 and 18, thereby changing the swing range of the lever 3 and the speed of rotation of the part 6. In this case, the rod 16 fixed between the forks 12 and 13 restricts the movement of the lever 3 in the upper and lower position.

Fix part 6 on the shaft 5, pour in the container 1 a working medium, for example, abrasive granules or metal balls. Turn on the vibrator 21. Vibrating platform 2 with a container 1 fixed on it with a working medium, performs oscillatory movements. Under the influence of kinetic energy, the lever 3 with the clip 9 performs rocking movements.

In this case, the freewheel 10 rotates, it enters and disengages from the shaft 11. The shaft 11 rotates at a certain angle, as a result of which the shaft 5 rotates with the part 6. The indicator 20 allows you to track the speed of rotation of the part 6.

It is possible to process heavy parts or several parts that are simultaneously mounted on the shaft. To do this, install discs 4 of various weights.
