Abstract

Patente de Invenção:<B>"MáQUINA-FERRAMENTA ELéTRICA"<D>. Em uma máquina-ferramenta elétrica que trabalha de forma rotativa e/ou por percussão como sejam martelo de furar ou martelo de percussão ou máquina de percussão/furadeira, que apresenta uma carcaça de máquina (10) com um eixo porta-ferramenta (11) acionado eletricamente para o acionamento de um porta-ferramentas (12) assim como um mecanismo de percussão mecânico (16) que apresenta um batedor (18) que acelera direta ou indiretamente o cabo de ferramenta no seu sentido axial e o solicita com choques e apresenta uma unidade de acionamento (20) que deriva a aceleração do batedor (18) a partir de um movimento de rotação, abrange a unidade de acionamento, para a realização de um maior número de rotações do eixo porta-ferramenta (11) pela dispensa de um eixo de transmissão intermediário, um elemento de apalpação (21) deslocável axialmente e que gira em sincronismo com o eixo porta-ferramenta
