The Design of Portable Drilling Machine for The Railway Rails
Abstract:This text analyzed the present condition of Chinese domestic and international railroad steel rail borer machine and designed a kind of new model of small scaled then the hold type railroad steel rail borer machine.The borer machine from bay, clip track mrvhsnidm, gear rack drive and small scaled electric drill composition.Adopted to imitate a shape clamping, effectively raised the location accuracy of drilling, clipped track mrvhsnidm the adoption quickly clip tight mrvhsnidm and availably reduced a hours of labour and clipped tight the force used is also little.Then the transform merit of the hold type railroad steel rail borer machine mainly embodiment lowered the labour intensity of blacksmith, raised a working efficiency.
Key words:Steel rail borer machine;The dead point cotter dies;Four-bar linkage
