BEST MODE FOR CARRYING OUT THE INVENTION
First, an embodiment of the present invention will be described with reference to FIGS. Reference numeral 1 denotes a member made of a magnetic material that is perforated. Here, a steel plate having a thickness of 3 mm is used, and the above-described electric control box made of a steel plate is a typical example. The plate 2 is 6 mm thick, 40 mm long and 70 mm wide, and has a magnet embedded therein. The magnet has two functions of adsorbing chips and adsorbing the plate material 2 to the member 1. Therefore, the circular magnet 3 is provided at the center of the plate 2, and the elongated rod-shaped magnet 4 is provided along the lower end of the plate 2. The two magnets 3 and 4 are embedded in the plate 2 and covered with a cover plate 5 as shown in FIG. The plate member 2 is preferably made of a non-magnetic material in order to make the attractive force of the magnet to the cutting chips and the member 1 more strongly act. Here, stainless steel is used, but copper alloy or synthetic resin may be used. Good.
[0005]
The plate 2 is erected vertically with respect to the member 1 so as to form a rectangular enclosure as shown in FIG. 1, and a hole is formed in the member 1 by inserting a drill from the direction of arrow 6. The chips generated at this time are prevented from being adsorbed on the inner surface of the plate material 2, especially near the magnet 3, and scattered to the outside. In the case shown in FIG. 1, it is convenient to arrange the plate material on both the front side and the rear side of the member for complete prevention of scattering.
[0006]
When the member 1 is standing up and down as shown in FIG. 1, the work can be performed while making the plate member 2 open in the shape of a U-shape and visually observing the tip of the drill. This makes it possible for the chips to fall into a U-shape because the chips fall downward. Furthermore, it is also possible to set two magnets 3 side by side or to make one large rectangle one to widen the attraction range. The magnets 3 and 4 are separated into two magnets. The large magnet is used as one magnet, and both the function of adsorbing the chips on the plate 2 and the function of adsorbing the plate 2 on the member 1 are 1 It is also possible to fulfill it individually.
[0007]
When the plate 2 is raised in a square shape as shown in FIG. 1, it is important that one plate and an adjacent plate are not easily separated or shifted. For this purpose, a connecting means 8 for another plate is provided at the end of the plate. FIGS. 4 to 7 show an embodiment of the connecting means 8, in which a pipe member 9 is welded to one end of the plate member 2 and a shaft member 10 is installed at the other end of the plate member 2. FIG. Since the shaft member 10 is disposed at a position slightly away from the end of the plate 2, the support piece 11 is welded to the end of the plate 2 for that purpose, and the shaft member 10 is fixed to the end. By inserting the shaft member 10 of one plate member 2 into the pipe member 9 of the adjacent plate member 2 as shown in FIG. In FIG. 6, the two plate members 2 and 2 intersect at a right angle. However, when this is an acute angle, that is, when the enclosing state in FIG. Does not work well, it is good to round or chamfer this corner 12.
[0008]
FIG. 7 shows a case where the member 1 has a step portion 13. At this time, the shaft member 10 has penetrated deeply into the pipe member 9, and the adjacent plate members 2 and 2 have shifted by a dimension matching the step portion 13. In this state, the plate members 2 and 2 are stuck to the member 1 and stand upright. In order to cope with such a step, the coupling means 8 installs a short pipe member 9 at the center in the vertical direction as shown in FIG. 4, while the shaft member 10 has a small support piece 11 arranged at the top and inserted. The length is large.
[0009]
FIG. 8 shows a case where five plate members 2 are combined in a pentagonal enclosure using five plate members 2. As shown in FIG. However, it is convenient to make it easier to cope with the situation of drilling.
[0010]
9 and 10 show a modification of the connecting means 8. FIG. An elongated magnet 14 is embedded in one end of the plate 2 and a cover plate 15 made of a non-magnetic material is attached thereto by bonding or welding, and an adsorbent 16 made of a magnetic material, for example, iron, is welded to the end of the other plate 2. The adsorbent 16 has a semicircular cross section, and an arbitrary angle can be selected as shown in FIG. As can be understood from FIG. 4 described above, the plate member 2 has the magnet 14 at one end and the adsorbent 16 at the other end.
[0011]
FIG. 11 shows a case in which a cover plate 17 is provided on the plate material 2 in case chips may be scattered in a direction opposite to the arrow 6 in FIG. 1 for some reason. In this case, since the cover plate 17 is openable and closable, the shaft 19 is supported by brackets 18 fixed at both ends.
[0012]
【effect】
According to the present invention, since the plate material in which the magnets are embedded is made to stand on the member made of a magnetic material capable of being perforated, chips from a drill are prevented from being adsorbed on the inner surface of the plate material and scattered around. Is done. Since the magnet has two functions of adsorbing chips and adsorbing the plate material to the members, the adsorbing of the chips and the erecting of the plate material can be achieved only by the magnet, which is structurally simple and easy to use in various places. Become good. By properly combining several prevention plates, an enclosing form suitable for the state of the perforated portion, such as a U-shape, a triangle, a square or a pentagon, can be easily obtained. Further, by preparing several types of dimensions of the prevention plate, a more flexible usage is realized.
Since the connecting means for the other plate material is provided at the end of the plate material, even if any external force such as contact of a drill acts on the plate material, the enclosing state is not easily disturbed. By adopting a combination of a pipe member and a shaft member as the connecting means, the shaft is simply inserted into the pipe, so that the handling is very simple and the structure is also simplified. it can. Further, since the coupling means is a magnet provided at the end of the plate material, the shape of the prevention plate is further simplified as compared with the aforementioned pipe material and shaft member, which is advantageous in handling.
By providing the cover plate on the plate material, even if the chips may be scattered to the outside in a direction opposite to the direction in which the drill enters, it can be completely stopped.
Although it is not an effect corresponding to the configuration of the claims, it is apparent from FIG. 4 that the shaft member is set long and a pipe material much shorter than that is installed at the center of the plate material end portion, as is apparent from FIG. Such a stepped member can be well adapted to form the surrounding shape of the plate material. Further, since the rounded adsorbent is fixed to the end of the plate as shown in FIG. 10, it is easy to optimize the enclosing form by arbitrarily determining the intersection angle of the plate.
