Description

Technical Field

[0001] The utility model relates to the technical field of radial drilling machines, in particular to a radial arm and a radial drilling machine. Background Art

[0002] A radial drilling machine is a drilling machine with a rocker that can rotate and rise and fall around a column, and the spindle box usually moves horizontally on the rocker. When drilling holes on a vertical drilling machine, the centering of the tool and the workpiece is achieved by moving the workpiece, which is obviously very inconvenient for some large and heavy workpieces; while a radial drilling machine can use the position of the moving tool axis for centering, which brings great convenience to machining holes on large and heavy workpieces in single-piece and small-batch production.

[0003] In the existing radial drilling machines, the sliding of the sliding arm along the main axis relies on the motor-driven screw to drive the sliding arm to move, and the motor also has to bear the weight of the sliding arm. In the process of lifting the sliding arm, the burden on the motor is relatively large, which can easily lead to damage to the motor in the long run, and then cause damage to the radial drilling machine. In addition, most driving wheels are single-slotted, and single-slot driving wheels are difficult to bear the workload of the radial drilling machine. Therefore, a radial arm and a radial drilling machine are needed to improve the above problems. Utility Model Content
