2. Description of the Related Art Drilling with a hand drill is quite common, but it is generally as easy as it is considered to accurately drill a hole with a certain diameter at a certain position on a workpiece. is not. In particular, since the hand drill fixes the position and orientation of the drill by hand, it is almost impossible to perform accurate drilling.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A description will be given below with reference to the drawings. It is assumed that a long lumber that is a workpiece W that has been lumbered is in a state of being carried on a roller 10 of a roller conveyor that is a horizontal transfer unit 1 (see FIGS. 1 and 2).

In order to define the position of the workpiece W, the elongated defining member 2 that abuts on the lower portion of the side surface of the punched surface S of the workpiece.
Are installed along the perforated surface S on one side of the transfer means 1.
The illustrated regulating member 2 is fixed to the side frame 11 of the transfer means 1,
It has a substantially inverted L-shaped cross-section with a defining surface 12 that projects from it towards the perforated surface S of the workpiece W and abuts against it.

The pressing member 3 presses the workpiece W against the regulating member 2 to fix the workpiece W, and one or more pressing members 3 are provided on the opposite side of the regulating member 2. The pushing member 3 is provided on the reciprocating device 13 such as an air cylinder, but it may be pushed by using a spring.

A hand drill 4 is provided on the side of the drilling surface S of the workpiece W. The hand drill 4 is not particularly limited in its type, size and driving method, but a general-purpose electric drill which is very commonly used may be suitable.

The drill mounting member 5 to which the hand drill 4 is detachably attached has a drill mount 8 for supporting the hand drill 4 on its upper end and a fixing member 9 for fixing the drill mount 8. It is desirable that the drill rest 8 has a portion 14 that engages with irregularities on the outer shape so that the hand drill 4 does not come off, and the fixing member 9 is not affected by the difference in size and shape of the hand drill 4. A structure that can be fixed so as to be tied to the stand 8 is preferable.

A slide mechanism 6 is provided for moving the drill mounting member 5 in the forward and backward directions with respect to the drilling surface S. The slide mechanism 6 is provided with a pair of parallel guide shafts 15 arranged in a direction orthogonal to the transfer direction, and a thrust bearing for moving both guide shafts in a direction orthogonal to the transfer direction, which is provided below the transfer means 1. 16 and.

The slide mechanism 6 need only be capable of moving the hand drill 4 in parallel, and need not be driven. But,
It is free to perform forward and backward movements by using piston drive and the like together.

The drill mounting member 5 is connected to the tip of the slide mechanism 6 via a connecting member 17. In the case of the first embodiment shown in FIGS. 1 to 3, the drill mounting member 5 is adjusted for adjusting the drilling height. A mechanism 7 is provided in connection with this connection.

In the adjusting mechanism 7 according to the embodiment, the lower end of the drill mounting member 5 is rotatably supported by the center of the semicircular coupling member 17, and is coupled to change the drill height depending on the degree of rotation. A large number of adjusting ports 18 are concentrically opened in the member, and fixing pins 19 inserted into the adjusting holes 18 are attached to the drill mounting member 5.
It is adapted to be attached to the long groove 20 on the side surface of (FIG. 3). Reference numeral 21 denotes a rotary shaft of the drill mounting member 5.

A modification of the adjusting mechanism 7 is shown in FIG. 4, which comprises a drill mounting member 5 and two upper and lower members 22,2.
The upper member 22 is provided with a mount 8 and the lower member 23 is divided into three parts.
The upper member 22 is vertically movably fastened to the lower member 23 by the fastening member 24, and its height can be selected at the position of the adjustment hole 25 provided in the upper member 22. Have a configuration.

When the workpiece W arrives at the installation location of the device of the present invention having such a structure, it is detected by the detecting means 26 such as a limit switch and the pressing member 3 is operated by the signal. You can After the workpiece W is fixed to the regulating member 2 by the pressing member 3, the hand drill 4 is activated and moved by the slide mechanism 6 toward the drilling surface S.

When the bit 27 of the hand drill 4 hits the drilling surface S and starts drilling, the blade acts so as to bite in a spiral shape. 2 and the guide shaft 15 of the slide mechanism 6 move to the right in FIG. 2 to perform a predetermined punching operation. After that, the operator may return the drill mounting member 5 to the original position.

[0017]

As described above, according to the present invention, the generally used hand drill 4 can be detachably attached to the drill attachment member 5 which can be moved straight by the slide mechanism 6, and can be used for transportation such as a conveyor. Since it is possible to position and fix the workpiece as it is on the means 1 and to perform the necessary punching, it is possible to perform the required and sufficient precision drilling without an expensive and precise punching machine. Since the hand drill 4 can be opened and the hand drill 4 that is close at hand can be used as it is, there are significant practical effects such as expansion of its application.
