Abstract

MANDRIL PARA USO COM UMA FERRAMENTA ELéTRICA. é descrito um mandril que aperta ou afrouxa automaticamente os mordentes do mandril em resposta à rotação de um eixo de acionamento de ferramenta elétrica ou eixo de caixa de engrenagem. O mandril possui um corpo, diversos mordentes e um anel de ajuste que é rosqueadamente encaixado com os mordentes. O corpo do mandril e o anel de ajuste são, cada um, seletivamente rotativamente acoplados ao eixo da caixa de engrenagem da ferramenta elétrica. O corpo do mandril é também seletivamente rotativamente acoplado ao alojamento da ferramenta elétrica. é provido um seletor de modo para colocar o mandril no modo de perfuração ou modo de auto-travamento. No modo de perfuração, o corpo do mandril é rotativamente acoplado ao eixo da caixa de engrenagem e é rotativo em relação ao alojamento da ferramenta elétrica, permitindo deste modo que o corpo do mandril seja rotativamente acionado pelo eixo da caixa de engrenagem. No modo de auto-travamento, o anel de ajuste é rotativamente acoplado ao eixo da caixa de engrenagem e o corpo do mandril é rotativamente acoplado ao alojamento da ferramenta elétrica, para permitir que o anel de ajuste seja rotativamente acionado pelo eixo da caixa de engrenagem em relação ao corpo do mandril, de modo a apertar ou afrouxar os mordentes.
