(54) SURFACE POLISHING MACHINE

(57) Use: in machine tools for polishing stainless steel sheets. SUBSTANCE: machine includes a base, a rotation drive 9, spindles 2 with polishing elements 4. located on the branches of a magnetostrictive vibrator 1, mounted on supports 5-8 for rotation. The ends of the spindles located in the zone of maximum expansion of the vibrator are fixed on it. Due to the rotation of the spindles, their vibration and the table feed with the parts fixed on it, a mirror surface with an original pattern is formed on the surface to be treated. 5 ill.

about

The invention relates to machine tool industry and can be used in the processing of metals, in particular for polishing stainless steel sheet products.

Technical solutions are known for polishing parts, which are machine tools comprising a bed, a conveyor, an oscillation mechanism, and a carriage drive of a carriage with drums provided with polishing elements. Polishing is carried out by feeding a sheet (part) fixed to the conveyor. The polishing drums reciprocate and rotate. However, such devices have low productivity. The complexity of the design leads to the need for frequent repairs and the need for frequent repairs.

Closest to the claimed technical solution is a device for surface finishing. On the vertical shaft of the drive there are two conical flanges and a housing mounted rotatably relative to the axis of the drive and bearing horizontal spindles in contact with: the flange. A cylinder with a second conical flange is mounted on the flange. opposite end. The device is provided with means for vertically moving each spindle and for providing periodic contact of its cone with one of the flanges. Processing of the product is carried out by rotating the spindles around its own axes during the approach and removal of grinding elements to the product. However, an increase in productivity can be achieved by increasing the number of tool drums, which will complicate the drive rotation and start / 1; nb will complicate the changeover when changing the drums.

The aim of the invention is to improve the quality of the machined surface by applying reciprocating vibrations to the rotating spindle, which allows to reduce the height of the combs in various planes. . .

This is achieved by using a magnetostrictive vibrator with spindles mounted on it and provided with polishing elements to create polishing movements. The vibrator is rotatably mounted on supports, two of which are located in the zero tension zone and two end supports are located in the maximum tension zone. On the branches x of the vibrator mounted spindles with polishing elements,

moreover, in the zone of maximum tension of the vibrator, the ends of the spindle are fixed, and in the zone of zero tension they freely move along the surface of the vibrator.

Fig. 1 is a front view polishing machine; figure 2 is the same side view; in Fig.Z is a longitudinal section along the spindle block; figure 4 is a transverse section along the spindle block; on the

figure 5-plot of stretching magnetostrictive vibrator,

In the machine for polishing the surface spindle; the unit consists of a magnetostrictive vibrator 1, on the branches of which

spindles 2 and 3 are installed with polishing elements fixed to them 4. The vibrator 1 is mounted rotatably on two rolling bearings 5 and 6 located in the zero-tension zone and

on two supports 7 and 8 located at the ends. Spindles 2 and 3 are mounted on the branches of the vibrator 1 so that in the zone of maximum expansion their ends are fixed, and in the zone of zero tension freely

move along the cylindrical surface of the vibrator 1. In the zone of zero tension of the vibrator 1 there is a pulley 9, a ring of the current lead 10, soldered to the shell of the vibrator 1 and the current lead 11 mounted on

separate bracket. For the installation of the processed sheets 12 and 13 there is a table

14. On the carriage 15 are the drive motor 16 and the spindle unit 17. The machine operates as follows.

The processed sheets 12 and 13 are laid and fixed on the table 14. The carriage 15, on which the drive 16 and the spindle unit 17 are mounted, is lowered and presses the polishing elements 4 to the machined

the plane of the sheets 12 and 13. The drive 16 is turned on, from which the rotation through the V-belt drive is transmitted to the pulley 9 and

magnetostrictive e-mail 1. The vibrator 1 is turned on and the spindles 2 and 3 are oscillating with

 maximum amplitude. Thank you

plentiful supply of abrasive suspension, on

the top forming a polishing zlondov 4 there is a cooling of the vibrator 1.: - v; V-VS :: v; -; c: -: -: / Г- / К- - - ..:, -;
