Abstract

The invention provides a tool positioning device with simple structure, increased processing precision and work efficiency. A hollow cylindrical ring sleeve (8A1-8A3) comprises a hole (8a) engaged with the tool in a center part along the axle direction (O) and is clamped on the head between the tool and the tool. An upper end surface (8Au) along the axle direction on the ring sleeve (8A1-8A3) forms the surface vertical to the axle (O). In addition, the ring sleeve (8A1-8A3) comprises an inclined surface (8Ad) amplifying from the lower end to the upper end along the axle direction. Thus the inclined surface may form a conical surface with an included angle between the inclined surface and the axle being 5-85 degree and also may form a curved surface with an included angle between the tangent of the outer edge intersecting to the hole (8a) and the axle (O) being 5-85 degree.

Description

technical field

[0001] The present invention relates to a hollow cylindrical tool positioning device that has a hole for fitting a tool at the central portion in the axial direction and is clamped to the tool to position the head end of the tool. Background technique

[0002] Figure 7 It is the main part front view of the conventional printed circuit board processing machine, Figure 8 is a front sectional view of the tool holder.

[0003] Figure 7 Among them, on the table 1 of the printed circuit board processing machine 100, the printed circuit board 2 and the drill holding device 50 holding the drill 3 as a tool are placed. The table 1 is supported by a guide device (not shown). The nut 4 fixed on the bottom of the workbench 1 is screwed with the feed screw 5 . The feed screw 5 is rotated by a servo motor (not shown), and moves the table 1 in a front-rear direction perpendicular to the drawing.

[0004] The slider 23 is supported by an unillustrated guide. A nut 24...
