Abstract

"APERFEIçOAMENTO EM DISPOSITIVO MANDRILADOR PARA ACABAMENTO DE FUROS DE ALTA PRECISãO E MEIOS DE SUPRESSãO DE FOLGA" do tipo que possui um membro (10) suporte de ferramenta móvel geralmente perpendicularmente ao eixo longitudinal de um corpo cilíndrico (2). O movimento do membro (10) suporte de ferramenta é causado pela rotação do anel rotativo (3) que está montado para rotação sobre o mencionado eixo longitudinal, essa rotação do anel (3) age para movimentar uma travessa (5) ao longo do eixo longitudinal. A travessa (5) se movimenta e está fixada junto à uma haste alongada (7) com extensão oblíqua (8). A extensão oblíqua (8) está alojada deslizantemente dentro do membro (10) suporte de ferramenta. A travessa (5) se estende substancialmente perpendicular ao eixo longitudinal do corpo cilíndrico (2) e possui nas suas extremidades roscas (5"') engatadas com a rosca externa (3') do anel rotativo (3). O movimento axial da travessa (5) ocorre dentro de um rasgo (24) axialmente estendido no corpo cilíndrico (2).
