Traditionally, various parts of boards such as printed circuit boards,
There is a drilling machine that automatically changes the drill bit to make a hole of a desired diameter. This is done by first moving the spindle onto the desired drill among the various drills provided on the tool post stand, then lowering the spindle to grip the drill at the tip of the spindle, and then moving the spindle onto the workpiece. The drill is moved to an arbitrary location on the surface to be machined, rotated and lowered, and then held in a collet to drill a hole in the workpiece.

By the way, such a drilling machine is provided with a pressure shaft at the tip of its spindle. This presser shaft consists of a dust collection cup to suck up and discharge chips generated during drilling, and a workpiece holding bush to prevent the workpiece from floating up during drilling, but conventionally, these were integrated into one piece. It was configured. The diameter of the hole through which the drill is inserted into the workpiece holding bushing has to be slightly larger than the outer diameter of the tool post in order to be able to replace the drill, so it has become considerably larger than the diameter of the drill.
For this reason, when the thickness of the plate to be machined is thin, the periphery of the machined hole rises due to the vacuum force for sucking and discharging chips, resulting in frequent burrs.

〔考案の目的〕[Purpose of invention]

The attachment and detachment of the work holding bushes 6b, 6ba, and 6bb mentioned above will be explained in detail with reference to FIG. In FIG . 6, parts that are the same as or equivalent to those in FIGS. 1 to 5 are given the same reference numerals. It is made slightly larger than the diameter of the flange 62, and when the spindle 5 moves above the hole 61, descends, moves in the direction of arrow A or B, and then rises, the workpiece holding bush 6b is removed from the dust collection cup 6a. The presser bush is detached from the holding base 9 and returned. Here, a groove 63 is cut in the direction of arrows A and B from the hole 61 of the workpiece presser bushing holder 9 with a width t 2 larger than the thickness t 1 of the collar 62 of the workpiece presser bushing 6b, and a groove 63 is cut in the direction of the arrows A and B of the workpiece presser bushing holder 9. When moving in the A or B direction, the work holding bush 6b moves using it as a guide. Also, the hole 64 of the dust collection cup 6a of the work holding bush 6b
The diameter D 2 of the fitting part 65 is made slightly smaller than the width l 1 of the elongated hole 66 which communicates with the hole 61 and is provided with the groove 63, so that the fitting part 65 can move inside the elongated hole 66. It has been made possible. Incidentally, when the dust collecting cup 6a and the work holding bush 6b are fitted into the hole 64 with a fitting portion 65, the O-ring 16 prevents them from coming off easily.

As described above, according to the present invention, the dust collecting cup attached to the press shaft spindle side and the work holding bushing which can be attached to and detached from the dust collecting cup are separately configured, and after the drill is attached to the spindle, Since the workpiece holding bushing is attached to the dust collection cup, the inner diameter of the workpiece holding bushing (drill insertion hole diameter) can be set as small as close to the outside diameter of the drill. This makes it possible to hold the workpiece (flat plate-shaped object to be machined) closer to the machining area, and prevents burrs from forming around the periphery of the machined hole even when the workpiece is thin, resulting in high-quality hole drilling. The effect is that processing is achieved.
