Description

Horizontal Drill Machine {HORIZONTAL DRILL MACHINE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal drill machine, and more particularly, to a horizontal drill machine capable of drilling a groove or a hole in an inner circumferential surface of a long workpiece.

The horizontal multiaxial drilling machine is capable of simultaneously cutting a workpiece having a plurality of holes through it, such as an engine block of an automobile, with the same precision.

That is, the horizontal multi-axis drilling machine is optimized for mass production.

Such a horizontal multiaxial drilling machine is capable of arbitrarily adjusting the position of a spindle, rotating a main spindle of the spindle through a middle gear shaft and a plurality of spindle gears, and transmitting the spindle via a drill shaft via two free joints.

However, such a drive transmission method must take the following inconvenience.

That is, the horizontal multi-axis drilling machine takes a long time to prepare for the next work, such as machining one side of the workpiece, separating the processed workpiece from the holding device, and then fixing the other side facing the drill. .

In order to solve such a problem, there can be mentioned, for example, "Horizontal multi-axis drilling machine" (hereinafter referred to as "prior art") of Publication No. 20-1991-0004361.

The prior art has improved and further improved the structure of a tool guide apparatus and a tool, and a speed change device which can be shifted easily, as well as a rotatable index table of a work clamping device.

However, in the conventional horizontal multi-axis drilling machine and the prior art, drilling shafts are used when working on pipes or grooves having an inner circumferential surface which is formed long in the longitudinal direction, that is, when holes or grooves are formed on the inner circumferential surface of the pipe or on the inner surface of the pipe. There is a fear that a sagging phenomenon may occur along the longitudinal direction of the drill shaft.

In particular, the conventional horizontal multiaxial drilling machine and prior art have been problematic in that the driving force is not completely transmitted due to the sagging phenomenon of the drill shaft, so that the problem of defects in the work results has been reduced.

Publication No. 20-1991-0004361
