Abstract
The utility model discloses a drilling tool which comprises a drill chuck, a rotary drilling rod and a feeding drilling rod. The drilling tool is characterized in that belt pulleys are respectively installed on the drill chuck and the rotary drilling rod, and a supporting plate connected with the drill chuck is additionally arranged on the feeding drilling rod. The belt pulley installed on the rotary drilling rod is fixed through a locking nut. The supporting plate is fixed on the feeding drilling rod through a fixture, a fixing bolt is arranged on the fixture, two bearings are arranged at the upper part of the drill chuck for fixing the supporting plate, and the supporting plate additionally arranged on the feeding drilling rod can drive the drill chuck to rotate for 360 degrees. The utility model has the advantages that the drilling and the tapping can be performed in the narrow space and inside the box body parts without using other equipment, thereby the operation is convenient and the cost is saved.
Description
Technical field
The utility model relates to a kind of drilling tool, is specially adapted to the drilling tool in the little working space of mountain pass and box parts internal bore and tapping.
Background technology
Existing drilling tool, particularly radial drill, bench drill etc. to the little working space of mountain pass and box parts internal bore and tapping the time, because inconvenience is used in the restriction in space, cause the waste of time and equipment.
Summary of the invention
The utility model proposes the existing radial drill of a kind of utilization, bench drill, by transforming, can be at the drilling tool of the little working space of mountain pass and box parts internal bore and tapping.Task of the present utility model is finished like this: install a gripper shoe on the feeding drilling rod additional, gripper shoe is connected with drill chuck again, respectively install a belt pulley on rotary drill rod and the drill chuck additional, drive by belt, when rotary drill rod rotates, drive belt pulley, drill chuck is worked asynchronously, the utlity model has following effect: do not use miscellaneous equipment, can hole and tapping convenient and saving cost in little space of mountain pass and box parts inside.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a vertical view of the present utility model
The drawing explanation
1 bearing block 2, bearing 3, belt pulley 4, gripper shoe 5, feeding drilling rod 6, stiffener 7, anchor clamps 8, locknut 9, rotary drill rod 10, set bolt 11, belt 12, drill chuck
The specific embodiment
Describe embodiment in detail in conjunction with above accompanying drawing, a belt pulley 3 will respectively be installed additional on drill chuck 12 and the rotary drill rod 9, belt pulley 3 on the rotary drill rod 9 is fixing by locknut 8, locknut 8 internal diameters are taper, one end of gripper shoe 4 adopts two bearings 2 and bearing block 1 to be fixed on drill chuck 12 tops, the other end is that anchor clamps 7 are installed on the feeding drilling rod 5, anchor clamps 7 are fixing by set bolt 10, because gripper shoe 4 is installed on the feeding drilling rod 5 by anchor clamps 7, so gripper shoe 4 can drive the 360 degree rotations of drill chuck 12 levels, the two ends of gripper shoe 4 add stiffener 6 to increase the intensity of gripper shoe 4, two belt pulleys 3 are connected by belt 11, when rotary drill rod 9 rotates, drive belt pulley 3 rotations, drill chuck 12 is worked asynchronously.
