Abstract

ferramenta de impacto. é fornecida uma ferramenta de impacto que é capaz de detectar, de forma mais confiável, excesso de torque de reação que atua sobre um corpo de ferramenta. mais especificamente, é fornecida uma ferramenta de impacto portátil que faz com que uma ferramenta de ponta (119) gire de modo a executar uma operação de usinagem predeterminada, sendo que a ferramenta de impacto portátil compreende um corpo de ferramenta (103), um motor (111) que é alojado no corpo de ferramenta (103) e faz com que a ferramenta de bico (119) gire, um primeiro sensor (151) que detecta o estado de torque da ferramenta de ponta (119), um segundo sensor (159) que detecta o estado de movimento do corpo de ferramenta (103), e um mecanismo de desligamento de torque (134) que desliga a transmissão de toruqe entre o motor (111) e a ferramenta de ponta (119). o mecanismo de desligamento de torque (134) é configurado para desligar a transmissão de torque sob a condição de que o primeiro sensor (151) e o segundo sensor (159) detectem, respectivamente, um valor de limiar predefinida para o primeiro sensor (151) e para o segundo sensor (159).
