Abstract
Drill for drilling rails and track rigs, in railroad applications, including a body which supports a motor driving a drilling tool through a reduction unit. Elements are provided for the translatory motion of the drilling tool with respect to the body. There are also elements for removably fixing the body with respect to the element to be drilled.
Claims32
Drill for drilling rails and track rigs, in railroad applications, comprising:
- a body;
- a reduction unit supported by said body;
- a motor for driving a drilling tool of said drill, said motor being supported on said body, and said reduction unit being interposed between said motor and said drilling tool;
- translatory motion means for causing translatory motion of said drilling tool with respect to said body, said translatory motion means comprising a hollow shaft forming at an end thereof a supporting spindle for said tool, said shaft being movable to an advanced drilling position along a longitudinal axis of said tool and having a duct extending thereinto along said longitudinal axis up to said tool;
- fixing means for removably fixing said body with respect to an element to be drilled;
- and
- a scrap expelling device for expelling drilling scrap, said expelling device comprising an abutment rod, said rod being fixedly supported at an end thereof at said body for extending in said duct inside said hollow shaft with a further free end thereof being arranged proximate to said supporting spindle, said free end of said rod expelling the drilling scrap upon a return movement of said shaft from said advanced position.

Drill for drilling rails and track rigs, in railroad applications, comprising:
- a body comprising a first wing and a second wing;
- a reduction unit supported by said body;
- a motor for driving a drilling tool of said drill, said motor being supported on said first wing of said body, and said reduction unit being interposed between said motor and said drilling tool;
- translatory motion means for causing translatory motion of said drilling tool with respect to said body;
- and
- fixing means for removably fixing said body with respect to an element to be drilled;
- wherein said means for removably fixing said body with respect to the element to be drilled comprises interchangeable jigs, said jigs being removably coupled to a free end of said second wing of said body.

Drill for drilling rails and track rigs, in railroad applications, comprising:
- a body comprising a first wing and a second wing;
- a reduction unit supported by said body;
- a motor for driving a drilling tool of said drill, said motor being supported on said first wing of said body, and said reduction unit being interposed between said motor and said drilling tool;
- translatory motion means for causing translatory motion of said drilling tool with respect to said body;
- and
- fixing means for removably fixing said body with respect to an element to be drilled;
- means for an initial positioning of said actuation lever;
- wherein
- said initial positioning means comprises a cap which is fixed to an end of said actuation lever, said cap being rotatably coupleable around a tang, said tang being axially aligned with, and fixedly coupled to a driving shaft of said gear which meshes with said slider, a polygonal bar segment being furthermore provided which is accommodated in a polygonal seat formed by said tang, said bar being removably engageable in a polygonal cavity formed by said cap for jointly rotationally coupling said cap to said tang, a stem being connected to said bar, said stem ending with a button that protrudes from said cap, said polygonal bar segment being removably disengageable from said polygonal cavity for an initial positioning of said actuation lever.

Drill for drilling rails and track rigs, in railroad applications, comprising:
- a body;
- a reduction unit supported by said body;
- a motor for driving a drilling tool of said drill, said motor being supported on said body, and said reduction unit being interposed between said motor and said drilling tool;
- fixing means for removably fixing said body with respect to an element to be drilled;
- translatory motion means for causing translatory motion of said drilling tool with respect to said body, said translatory motion means comprising a hollow shaft forming at an end thereof a supporting spindle for said tool, said shaft being movable to an advanced drilling position along a longitudinal axis of said tool;
- and
- a scrap expelling device for expelling drilling scrap, said expelling device comprising an abutment rod, said rod being fixedly supported at an end thereof at said body for extending inside said hollow shaft with a further free end thereof being arranged proximate to said supporting spindle;
- a refrigeration system for providing cooling-lubricating fluid to the drilling tool, said refrigeration system comprising a cylindrical hole extending inside said rod, a duct extending in said hollow shaft along said longitudinal axis up to said tool, said hole and said duct being in fluid communication, a fluid coupling and a pressure relief valve mounted in said body, said fluid coupling and said relief valve being in fluid communication with said hole and said duct for introducing and respectively letting off said fluid from said refrigeration system, said fluid coupling being located at a lowest point of said refrigeration system.
