Description

Bidirectional rotary tool rest mechanism of electrode grinding drilling machine

Technical Field

The utility model relates to a two-way rotary tool rest mechanism of electrode coping drilling machine.

Background

The process of polishing the electrode cap of the manual welding tongs comprises the following steps: firstly, placing an electrode cap to be polished on an electrode rod; secondly, the polishing handle is pressed down to perform feeding polishing on the electrode cap; thirdly, pressing a manual uncapping switch after visually confirming that the grinding of the electrode cap reaches the standard;

the grinding of the electrode is mainly to rotate the main shaft to drive the blade to cut, and to manually control the axial feed motion of the blade to finish the grinding of the electrode. The blade edge angle is required to complete cutting, and is also required to bear large axial impact, so that the abrasion degree is large, and the blade edge angle is required to be replaced periodically. The cutting edge of the side blade fixed by the tool rest is not polished, so that no abrasion is caused; the abrasion degree of the edge angle of the grinding side is large after grinding, when the blade is replaced, the abrasion difference of the edge angles of the two sides causes the waste of the use of the blade, and the utilization rate of the blade in the grinding mode is only 50%.
