(54) DEVICE FOR ARRANGEMENT BALLS

one

The invention relates to the field of ball production and can be used in the construction of machine tools for the processing of balls.

Basically auth. St. No. 52818O described by ycrpofcTBO for final processing of balls.

This device contains two disks, one of which is master and is associated with the drive, and the other is working, which has the possibility of axial movement and pressure relative to the master disk. The working disk is provided with rings mounted in a concentric groove made therein, which are connected to the disk by means of axially elastic elements and radially, while the axially elastic elements of different rings are stiff. The axially elastic elements are made with rigidity, the smaller, the larger the diameter of the rings with which the OR1 are connected, and the elements elastic in the radial direction are made in the form of elastic inserts placed in grooves wedged in rings and rings.

 grooves of the working disk. Concentric grooves are made on the rings in the master disk to install the balls to be processed.

The known device does not provide high performance when grinding extremely precise balls.

The aim of the invention is to further improve the quality and productivity of the processing of the balls.

This is achieved by the fact that the device is equipped with ultrasonic concentrators located on the working disk, connected with elastically mounted rings, of the working disk.

FIG. 1 shows the proposed device, a radial section; in fig. 2 - the same, top view.

The device contains a drive-related drive 1, having the possibility of axial movement and pressure relative to the work disk 2, fitted with rings 4 installed with a gap in the concentric grooves 3 made therein, connected to the disk 2 by ytipyrnx in axial and} elements 5 and 0; In this case, uirugai B, the axial nuggets of elements 5 are made with an i-eM gesture less than the larger diameter 4, s.koutoulmi are connected, and elastic n; hell in the direction of the elements 6 Shdgaolt a, 1 in the form, elastic inserts, placed in the gaps between the trotrochkamn 3 and rings 4, Rings 4 and the vauishy disk 1 are tied to the trichoche tsanagzkl 7 for {shemesheki and processing iufipHKOB 8 besides sToroj on the working frames for working iufipHKOB 8 in addition to sToroj on the working frames for working iufipHKOB 8 In addition to sToroj for working schools, iufipHKOB 8 for working with iufipHKOB 8 In addition to sToroj for working iufipHKOB 8 in addition to sToroj for working schools, iufipHKOB 8 for working with iufipHKOB 8 in addition to sToroj for working iufipHKOB 8 1g nomeslin springs 9 n Wing 10 with tatseelcha. These golovkami 11 are ultrasonic 1k locks 12, movably connected to rings 4. Ultrasonic head 12 contains a magnetostrictor, made up of a set of shsho tnn, forming a core 13, on which the 1st winding is wound 1 from a wire with a water resistant cable. an acoustic waveguide illustrator hub 15, rigidly connected to the core 13 maptostrictorg, which is scattered with a glass 16, which has fitting 17. Screws 10 pass through the hole 17 with a gap. On the glass 16, there is a thin-walled casing 18, in which provision is made for responses 19 and 2O for supplying and discharging a cooling fluid. To neutralize the oscillations of the free end of the magnetostrictor, prol laola 21 was installed at its non-working end, which was made on porous rubber. Ultrasonic head 12 is installed. on disk 2 in such a way that they are located in holes 15, which are located in disk 2. At the same time, the waterways are constantly in contact with the rings 4 with screws 10 and springs 9. Near each ring 4 on the disk 2 there are 1o at least three ultra-sonic heads. The device operates as follows. The balls 8, located in the grooves 7, are transmitted through the working disk 2 and the rings 4 to an operating force P. When, the atom is deformed by the elastic elements 5, as a result of which the rings 4 press on the waveguides 15, compressing the springs 9, which have been previously drained, KOTOja.ie from the back side abuts the cups 16, and the other into the disk-shaped heads 11, is pressed. install the necessary ultrasonic pressing force, 1x holok 12 to the rings 4. After the drive for the lead suit 1 is turned on and the pressure P is applied, ultrasonic heads 12 powered by the ultrasonic oscillator are connected to the device. At the same time, the amplitude and frequency of oscillations, the stiffness of the springs 5 9, the elastic elements 6, as well as the pressure P and the rotation speed of the working disk 1, are selected so as to cause the ultrasonic heads — rings — of the system. In addition, in order to align the working capacity of the central and peripheral rings, the ultrasonic heads associated with different rings have an amplitude and a frequency of oscillations in such a way that “4 I eat a larger ring diameter, the smaller the amplitude and frequency. The positive effect of the application of ultrasound is that when the balls are processed, a resonant mode of ultrasonic oscillations is reached, in which standing waves arise in waveguide 15, causing oscillations of the rings in the axial direction. This makes it possible to significantly reduce the amount of clamping force with a simultaneous intensification of the treatment process by reducing frictional forces and a more intensive effect of the finishing process on the surface to be treated. In addition, periodically changing the force effect causes additional damage to the balls and contributes to a more intensive and uniform application of traces of the tool on the surface of the balls. Due to this, the proposed device allows to improve pumps in while at the same time increasing the output of the finishing of the balls. The invention of the device for fine-tuning balls on the author. St. No. 52818О, differing from the fact that, in order to improve Ka4ecTw and processing performance, it is based on ultrasound-mounted hubs associated with resiliently mounted working disk rings.
