[Industrial applications]

 The present invention relates to a punching device.

[0002]

[Prior art]

 For example, in the case of assembling furniture, it is necessary to provide a large number of rows of holes for inserting bolts and wood screws in the component panel (work). Conventionally, when arranging such holes in a workpiece, marking is made in advance at the position where the holes are to be drilled in each workpiece, and a worker holds the electric drill by hand to drill each hole. The method is generally done. In addition, when there are many drilling points, a large drilling device with a large number of electric drills installed in a row is provided to improve work efficiency, and one workpiece is set in the drilling device, and a large number of electric drills are used. There is also a method of arranging holes one at a time.

[Problems to be solved by the device]

 However, the above-mentioned conventional drilling method has the following problems. First, in the method in which a worker holds an electric drill by hand to drill each hole, in the method in which one hole is drilled with a drill, the worker always holds the electric drill. Since it is necessary to work by working on it, the fatigue of the worker is remarkable. Furthermore, there is a problem that work efficiency is reduced due to fatigue, mistakes in drilling are more likely to occur, and the frequency of defective products increases. On the other hand, in the method using a large-sized drilling device, the problems such as fatigue of workers, resulting in reduction of work efficiency and occurrence of drilling errors can be solved, but since many electric drills are installed in a row, There is a problem that it has to be expensive. Therefore, an object of the present invention is to provide a punching device which is inexpensive and has good workability.

[0004]

Means for Solving the Problems In order to solve the above problems, the present invention has the following configuration. That is, a long guide rail, a piercing means that is movable along the guide rail in the longitudinal direction of the guide rail, and is capable of piercing a work, and the work at a specific position with respect to the guide rail. And a fixing means for fixing to.

[0005]

[Action]

 The operation will be described. Since the piercing means is provided so as to be movable along the guide rail in the longitudinal direction of the guide rail, the worker can perform the piercing work without holding the piercing means. Since the piercing means can move along the guide rail in the length direction of the guide rail, when arranging a large number of holes in a workpiece, simply set the guide rails parallel to the arranging direction of the holes and Can be set.

【Example】

 Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. In FIG. 1, 10 is a guide rail, which is a single metal linear rail. On the front surface of the guide rail 10, a large number of hemispherical recesses 12 are provided at predetermined intervals in the length direction. Although described in detail later, the recess 12 constitutes a positioning mechanism for a slider (described later), and is recessed at the same intervals as the intervals of a large number of holes arranged in the work 14. A scale 16 is printed on the front surface of the guide rail 10. The scale 16 can measure the distance and position the work 14 and the punching means (described later). The guide rail 10 is fixed to an appropriate support base 18 (see FIG. 2).

Reference numeral 20 denotes a slider, which is attached to the guide rail 10. The slider 20 is provided so as to be slidable in the length direction of the guide rail 10. The slider 20 is slidable in the length direction of the guide rail 10 by an appropriate mechanism (for example, a dovetail structure) (not shown), and cannot be removed from the guide rail 10. The slider 20 is provided with a positioning mechanism (described later) so that the slider 20 can be accurately positioned at a predetermined position with respect to the guide rail 10. Further, the slider 20 is provided with a position fixing mechanism (described later), and the position can be fixed on the guide rail 10 by rotating the handle 22a. Reference numeral 24 is an electric drill which is an example of a piercing means, and rotates the piercing blade 28 around the axis by the rotation of the motor 26. The rotation of the blade 28 enables the work 14 to be punched. The electric drill 24 is vertically movable along two guide poles 30a and 30b provided upright on the upper surface of the slider 20. The electric drill 24 is constantly urged upward by an urging means (not shown) such as a spring, and an operator grips the handle 22b and moves the handle 22b downwards against the urging force of the urging means. It is designed to move downward when pushed down. This downward movement makes it possible to punch the work 14. The electric drill 24 may be attached to the slider 20 so as to be vertically movable as shown in the figure, or may be attached to the slider 20 via a dedicated attachment jig so that the position of the blade 28 can be moved horizontally.

Reference numeral 32 is a stopper, which is fitted onto the guide pole 30a. The stopper 32 is slidable in the vertical direction along the guide pole 30a, and its position can be fixed by tightening the nut 34. The stopper 32 is provided to regulate the amount of downward movement of the electric drill 24. By adjusting the position of the stopper 32, the depth of the hole formed in the work 14 can be adjusted, or the through hole or the bottomed hole can be formed. It is possible to select a hole. Reference numerals 36a and 36b denote alignment parts, which are means for determining the position of the work 14 relative to the guide rail 10 (the position in the length direction of the guide rail 10).

As shown in FIG. 2, the alignment portion 36a includes a Z-shaped angle 38a and a plate 40a fixed to the angle 38a. The angle 38a is fixed to the left end of the guide rail 10 via a bolt 42. The plate 40a is fixed at a right angle with respect to the guide rail 10, and the right side surface serves as a reference plane for positioning the work 14. Therefore, the position of the work 14 in the length direction of the guide rail 10 is determined by bringing the left end surface of the work 14 into contact with the right side surface of the plate 40a. On the other hand, the alignment portion 36b includes a slide member 44 fitted onto the guide rail 10 and slidable in the length direction of the guide rail 10, an S-shaped angle 38b extending from the slide member 44, and an angle 38b. It consists of a plate 40b fixed to the. Since the alignment portion 36b is movable with respect to the guide rail 10, the work 14 can be sandwiched between the plates 40a and 40b. By sandwiching the work 14 between the plates 40a and 40b, the position of the guide rail 10 of the work 14 in the longitudinal direction is determined. When the handle 22c is tightened in this state, the alignment portion 36b can be fixed to the guide rail 10 at that position.

In FIG. 1 and FIG. 2, 46 a and 46 b are pressing portions that are an example of fixing means, and fix the work 14 at specific positions with respect to the guide rail 10. The pressing portion 46a is provided on the angle 38a of the alignment portion 36a and moves up and down when the handle 22d is rotated. On the other hand, the pressing portion 46b is provided at the angle 38b of the alignment portion 36b and moves up and down when the handle 22e is rotated. By moving the pressing portions 46a and 46b upward, the work 14 can be clamped between the lower surface of the guide rail 10 and the position of the work 14 with respect to the guide rail 10 can be completely fixed.

The positioning mechanism of the slider 20 will be described in detail with reference to FIG. The slider 20 attached to the guide rail 10 is provided with a through hole 48 that is perpendicular to the length direction of the guide rail 10, and a female screw is engraved inside. A ball joint mechanism including a ball 50 and a spring 52 is incorporated in the through hole 48. The ball 50 is constantly urged to the left by the spring 52. The left end of the ball 50 is formed in the lower portion of the slider 20 and slightly protrudes from the inner wall surface of the inverted U-shaped recess 54 that slides on the guide rail 10. The amount of protrusion of the ball 50 is regulated by the member 56. Further, the biasing force of the spring 52 can be adjusted by the screwing amount of the male screw 58 screwed into the through hole 48. The left end of the ball 50, which slightly protrudes from the inner wall surface of the recess 12, can be fitted into the recess 12 provided in the front of the guide rail 10, and when the slider 20 moves along the guide rail 10. When the ball 50 is pushed into the through hole 48 against the biasing force of the spring 52 and the ball 50 faces the recess 12, the left end of the ball 50 fits into the recess 12 and the slider 20 is positioned. It will be possible. The slider 20 may have a positioning mechanism other than that described above. If the position of the slider 20 should be set independently of the recess 12, it may be set by referring to the scale displayed on the scale 16. Good.
