Abstract

Использование: машиностроение; ручной инструмент дл клепки, рубки металла, забивки болтов с нат гом и других операций . Сущность изобретени : в корпусе 1 молотка закреплен ствол 3. В передней части ствола размещена втулка 4 с рабочим инструментом 5, в задней части - ударник 7 со спусковым механизмом 8. Спусковой механизм включает полый цилиндр 10 со скошенным торцом 11 и подпружиненные упоры 12. Упоры установлены в радиальных отверсти х 13 ударника. В хвостовой части рабочего инструмента 5 закреплен толкатель 19. Он проходит через осевой канал в ударнике 7 и взаимодействует с. поршнем 16. Упоры 12 перемещаютс по скошенному торцу 11 полого цилиндра и устанавливаютс . Ударник 7 под действием сжатого воздуха перемещаетс до соударени с рабочим инструментом 5, производ удар. 2 ил.Use: mechanical engineering; hand tools for riveting, metal cutting, bolt tightening and other operations. SUMMARY OF THE INVENTION: A barrel 3 is fixed in the case 1 of the hammer. In the front part of the barrel there is a sleeve 4 with a working tool 5, in the rear part there is a hammer 7 with a trigger 8. The trigger mechanism includes a hollow cylinder 10 with a beveled end 11 and spring-loaded lugs 12. Rest installed in the radial holes x13 of the striker. In the tail part of the working tool 5 is fixed a pusher 19. It passes through the axial channel in the drummer 7 and interacts with. the piston 16. The stops 12 move along the beveled end 11 of the hollow cylinder and are mounted. The drummer 7 moves under the action of compressed air before impacting with the working tool 5, producing a shock. 2 Il.
