Description

[Detailed Description of the Invention] The present invention relates to a steadying device used in a flexible multi-spindle drilling machine that simultaneously drills a large number of holes in a plate material.

As shown in Fig. 1, a flexible multi-spindle drilling machine has a fixed rail 1 mounted horizontally on the top of a column, and a plurality of sliding rails 2 protruding perpendicularly to the fixed rail 1 so as to be slidable. A plurality of spindles 3 are slidably attached to a rail 2.

The upper pulleys of each spindle 3 are connected by a belt (not shown) driven by a motor (not shown).

A table on which a workpiece is placed is provided below the spindle 3 and is movable up and down, and drilling work is performed by raising and lowering this table.

However, when there are a large number of spindles 3, correctly positioning them is a troublesome task, and there is a risk that the spindles 3 may swing during cutting. A kite board 5 having a number of spindles 3 and 4 is provided on the lower surface of the sliding rail 2, and each spindle 3
By passing this through the receiving hole 4, the positioning of the spindle 3 is facilitated, and the spindle 3 is prevented from swaying.

However, although this guide plate is extremely convenient because it can achieve the two purposes of positioning and steadying at the same time, on the other hand, each time the position of the hole to be drilled changes, a guide plate 5 with a corresponding receiving hole 4 is prepared. Another drawback arises in that it has to be done.

The present invention aims to solve the above-mentioned drawbacks and provide a steadying device that can prevent the spindle from wobbling, and can also easily adapt to changes in the mounting position of the spindle. The explanation will be based on the drawings.

The proposed device has an inverted mounting rod 11 as shown in Figure 2.
and a steady plate 12 that is removably connected to this. A long groove 13 is provided in the longitudinal direction of the center of the mounting rod 11, and a pair of bolt holes 15 are bored in the bottom surface of the tip of the bent part 14. Set up

The steady plate 12 includes a pair of opposing left and right plates 121.
A clamping hole 17 for clamping the spindle 16 is provided at the tip thereof, and a screw hole 19 is provided at the side surface for screwing in a connecting bolt 18 connecting both plates.

A bolt hole 2 is provided at the rear end of both plates 121 through which a connecting bolt 20 for connecting the plate plate 121 to the mounting rod 11 is passed.
1, pass the connecting bolt 20 through it, screw its tip into the bolt hole 15 of the mounting rod 11, and attach the plate plate 121.
is connected to the mounting rod 11.

Fig. 3 shows the steady rest device installed on a spindle.
Also remove the mounting arm 24 that protrudes from 3.

Then, the spindle 16 is held between its drill chuck 25 and the spindle body 23 by the clamping hole 17 of the steady plate 12 of this device.
Both plates 121 are connected with connecting bolts 18 while being clamped between them.

This is then attached to the mounting rod 11 using two fastening bolts 20.
Connect to.

After that, attach the fixing bolt 26 to the mounting rod 11 and the sliding rail 22.
, penetrate from the bottom to the top through each long groove of the mounting arm 24, and tighten with a nut 27, thereby fixing the present steadying device and the spindle body 23 to the slide rail 22 at the same time.

A recess 29 formed in the center of the long groove 28 of the sliding rail 22 is used as a stopper by inserting the head of the fixing bolt 26 when the device is not in use.

As explained above, in this case, the spindle body is tightened and fixed to the sliding rail by two-point support by the mounting arm protruding from the spindle body and this device, so that the spindle of the flexible multi-spindle drilling machine can be tightened and fixed. In addition to being able to easily eliminate vibration, the mounting rod is inverted so that it is clamped close to the tip of the spindle, which has a great anti-shake effect.

The broken steady plate can be separated and detachably connected to the mounting rod, so it can be attached to the spindle without removing the drill chuck, making installation extremely easy.

Mounting to the sliding rail is done by tightening a common fixing bolt that passes through the mounting rod and the mounting arm of the spindle body, so if the position of the hole to be drilled changes, you can easily loosen this fixing bolt. It has the convenience of being able to change the mounting position, and in this respect it has the advantage of being easier to handle than conventional kite boards.
