SU1222519A2 - Device for feeding coolant - Google Patents

Description

The invention relates to metalworking, in particular to the processing of metals with an abrasive tool using cutting fluids (coolant), and is an improvement of the invention according to the author. St. No. 554145.

The purpose of the invention is the expansion of technological capabilities by using the device when working with an oscillating motion tool.

FIG. 1 shows the proposed device; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The device contains two nozzles 1 and 2, symmetrically located at the ends of the circle 3, with pipes 4 and fittings 5 Nozzles 1 and 2 with screws 6 are fastened to tam 7, which in turn are fixed by screws 8 to a rolling pin 9 installed in guides sleeve 10 of the bracket 11, which is attached by screws 12 to the casing 13 grinding steep.

The device works as follows.

Coolant flows through pipes 4 and fittings 5 into nozzles 1 and 2, after which an oscillation of the circle is turned on. When the grinding wheel 3 moves in any direction, for example to the left, the gap between the nozzle 1 and the end of the circle decreases, and between the nozzle 2 and the end of the circle increases.

Since a hydraulic wedge with overpressure occurs between the nozzles and the circle surface, the value of which is inversely proportional to the gap between the nozzle and the circle surface, a force larger than that of the nozzle 2 acts on the end of the grinding wheel from the nozzle 1 side. The result is a force that tends to move the nozzles to balance these forces, and hence the size of the gaps between the nozzles and the circle, thereby maintaining a constant gap between the nozzles and the end of the circle. as the latter moves.

Thus, the advantage of the proposed device is the possibility of using it when working with an oscillating circle shlyofalny circle.
