The present invention discloses a boring machine which includes a table, a headstock unit which is installed on the table, a drive unit which drives the headstock unit to displace linearly along a first axis, a seat and a power unit. The seat provides for combining the headstock unit with the drive unit. The drive unit drives the headstock unit to displace linearly along the first axis, the power unit drives the headstock unit to rotate, and the power unit changes rotational speed by using the gnawing relation among main gears and speed-change gears in different sizes, so that the headstock unit can shift to different speed to cope with all kinds of machine processing. |

1. A boring machine comprising:
a table; a headstock unit, wherein the headstock unit is installed on the table and is sheathed with a gnawing tooth member; a drive unit, wherein the drive unit drives the headstock unit to displace linearly along a first axis, and is provided with a first power part and a lead screw which is driven by the first power part and is provided axially on the table; a seat, wherein the seat is provided with a fixing base to install and position the headstock unit, and an assembly part which is connected at a bottom of the fixing base and is combined with the lead screw; and a power unit, wherein the power unit drives the headstock unit to rotate, and is provided with a second power part, a main shaft, at least a speed-change shaft and at least a lever set, with the main shaft being axially provided with a main driving wheel and at least two main gears in different sizes, the main driving wheel being gnawed with the gnawing tooth member, the speed-change shaft being axially provided with two speed-change gears in different sizes, the second power part driving one speed-change gear to rotate, the lever set levering the speed-change shaft to displace linearly along the first axis to change the gnawing relation among the main gears and the speed-change gears. |
