Description

[Technical Field]

[0001] This invention belongs to the technical field of alignment gauges for drilling machines, and more specifically, to an alignment gauge, which is a jig that can easily and accurately align holes when drilling holes for passing overhead bolts or the like in concave parts (so-called C-channels) of long parts such as duct channels or raceways using a drilling machine. [Background technology]

[0002] In relation to a drilling tool for a long member, for example, Patent Document 1 listed below discloses a hydraulic drilling tool for boring holes in a lightweight channel material, which includes a hydraulic tool body having an oil tank, a hydraulic pump mechanism, and an internal hydraulic circuit, and a cylinder head and a piston that moves back and forth at the front, and a drilling mechanism detachably attached to the hydraulic tool body, the drilling mechanism comprising a punch having a flange at its base that is attached to the piston, and a head that is attached to the cylinder head and holds a pipe-shaped die that faces the punch, the head having a U-shaped recess at its side that can accommodate the lightweight channel material with its opening side facing forward, the die being screwed to the front so as to be movable back and forth, the die being able to hold the bottom surface of the lightweight channel material between the die and the head wall, and a return spring being embedded in the base end surface of the head that abuts against the flange and urges the punch, which moves forward, in a return direction (see claim 1, FIG. 2, etc. of Patent Document 1).

[0003] Furthermore, Non-Patent Document 1 below discloses a ductor punching tool that aligns a long member using an L-shaped stopper for size adjustment. That is, the center of the desired hole to be drilled in the long member is positioned at the center of the punch, the distance from that center position to the tip end face of the long member is measured using a tape measure, and once the desired position is set, the L-shaped stopper is fixed. Thereafter, the tip end face of the long member is brought into contact with the L-shaped stopper fixed in the above manner, and the handle (lever) of the punching device is pressed down to punch a hole in the long member with the punch.

[0005] [Non-Patent Document 1] https: / / www.youtube.com / watch?v=UyBNDboLeLETitle: "Electrical Work Handy Tools Negros Duct Drilling Tool MAKD" Summary of the Invention [Problem to be solved by the invention]

[0006] The hydraulic drilling tool described in Patent Document 1 can be carried around when drilling holes, but it still has the disadvantage that it cannot be set to an accurate drilling position when drilling holes in lightweight channel materials. Furthermore, the ductor drilling tool of Non-Patent Document 1 requires the user to position the center of the hole to be drilled in the long member at the center of the punch and then measure the distance from that center to the tip end surface of the long member, which is a cumbersome process. Moreover, once the desired position is determined, the L-shaped stopper is fixed in place, but the L-shaped stopper is unstable and requires adjustment each time, which is time-consuming and is considered a problem that needs to be solved.

[0007] Therefore, the object of this invention was made in consideration of the above circumstances, and is to provide an alignment gauge for a drilling device that can be attached to the drilling device and can easily and accurately align holes when drilling holes in long members (concave members) to pass ceiling bolts or the like through them at accurate positions.

[0032] A preferred embodiment of the alignment gauge for a drilling device of the present invention will be described below with reference to the drawings. As shown in Figures 11 and 12, this alignment gauge for the hole drilling device is attached to the hole drilling device 1 (Figure 1) to drill a hole 20 through which a suspension bolt or the like will pass at a predetermined position c in the long member 2 (Figure 14), and is a gauge that acts as a jig to accurately align the hole 20 to be drilled in the long member 2 (see Figure 10). Here, the long member 2 is a member such as a duct channel or raceway, commonly known as a C-channel or C-chan, and is a metal concave member such as a light channel steel whose cross-sectional shape has downward openings on both sides continuing from both ends of the upper surface, or a lip channel steel whose tip of the downward opening is slightly bent inward, as shown in Figure 14.

[0033] The hole punching device 1 is a manual device that punches a hole 20 at a desired position c in a long member 2. As shown in Figures 12 and 13, a base 12 connected to a long support member 13 is placed on the floor. A main body 14 equipped with a punch 10 for punching a hole 20 in the long member 2 and a receiving rod 11 for receiving the punch 14 are erected on the base 12. A handle 15 is attached to the main body 14, and the punch 10, which moves up and down via a link mechanism, is attached to the lower base end of the handle 15. Therefore, since the alignment gauge is attached to the main body 14 of the hole punching device 1, the tip surface 21 of one end of the long member 2 is fixed once the hole punching position is determined using the alignment gauge described below, and then the handle 15 is pressed down, causing the punch 10 to move downward and punch a hole 20 in the long member 2 between the tip surface 21 and the receiving rod 11.

[0034] The present alignment gauge shown in FIGS. 1 to 8 is as follows. This alignment gauge is a press-molded product of steel plate, and is composed of a main gauge plate 3, a plate-like body about 3 mm thick that is trapezoidal when viewed from above, and an L-shaped bent mounting piece 4. The main gauge plate 3 is not limited to a trapezoidal shape as in this embodiment, and may have any of various polygonal shapes. The mounting piece 4 has a vertical piece 41 that is approximately 37 mm wide and extends horizontally by approximately 16 mm, and is bent downward, at the center of the lower base 35 that forms one side of the trapezoidal main body gauge plate 3. The vertical piece 41 shown in Figure 5 has a mounting hole 40 drilled therein, and the mounting piece 4 is firmly fixed to the inside surface of the main body 14 of the drilling device 1 using this mounting hole 40 with bolts, so that the main body gauge plate 3 is attached to the drilling device 1 while maintaining a horizontal position.

[0035] The main gauge plate 3 has an overall trapezoidal shape, with a lower base 35 forming one end edge measuring approximately 97 mm, an upper base 34 forming the other end edge measuring approximately 37 mm, and a width dimension corresponding to the height from the upper base 34 to the lower base 35 measuring approximately 37 mm. In the center is a through hole 36 drilled with a diameter of approximately 23 mm so that the punch 10 of the hole punching device 1 can pass through. The leading edge 32 and the trailing edge 33, which slope stepwise from the front and rear ends of the upper bottom 34 to the front and rear ends of the lower bottom 35, respectively, are formed into a stepped alignment step portion 30 having multiple steps 31 that allow for free alignment of the holes 20 to be drilled in the elongated member 2 described above.

[0036] The alignment step 30 will be described (see FIGS. 2 and 3, etc.). The step portion 30 is formed as a plurality of steps 31 that are gradually inclined at 45° from an upper base portion 34 that forms the other side of the trapezoidal main body gauge plate 3 to a lower base portion 35 . The length from the through hole 36 of the alignment step portion 30 to the tip of each step 31 is set to the respective distance from the center of the through hole 36, as shown in Fig. 10. In this embodiment, the respective distances from the center of the through hole 36 are in the range of 20 mm to 50 mm, with a 5 mm pitch therebetween. In other words, the steps 31 of the step portion 30 are formed at a predetermined pitch toward the leading edge 32 and toward the rear edge 33, but in this embodiment, the predetermined pitch between the steps 31 is set to a 5 mm pitch, and the leading edge 32 and the rear edge 33 are each formed into a stair-like step 31. This is because, in normal use, holes 20 such as duct channels and raceways are frequently drilled in elongated members 2, adjusting the distance by 5 mm, in a range of 20 mm to 50 mm from the tip end surface 21 of the elongated member 2. Therefore, the length from the through hole 36 to the tip of each step 31 of the alignment step portion 30 and the pitch are not limited to those described above, and can be set to various lengths as necessary.

[0037] In addition, numbers a such as "20," "25," "30," "35," "40," "45," and "50" are displayed near each step 31 formed at 5 mm intervals on the main gauge plate 3, from the upper base 34 to the lower base 35. This serves as a guide when aligning the tip surface 21 of the long member 2 to the step 31 at the desired position on the alignment step portion 3, thereby improving the efficiency of the drilling work. In summary, the positioning step portions 30 are provided symmetrically in the left-right direction (symmetrical in the front-rear direction) with the through-hole 36 as the center, as shown in the example illustrated in FIG.

[0038] 7 and 8, an embodiment in which cross lines 37 are provided is also adopted. That is, cross lines 37 are provided on the outer periphery of the through-hole 36 on the top surface of the main gauge plate 30, extending in a cross shape in the vertical and horizontal directions and passing through the center of the through-hole 36. The center of this cross line 37 is located at the center position of the punch 10 (see symbol c), facilitating the setting work of fixing the elongated member 2 in the appropriate position (FIG. 10).

[0039] As described above, the alignment step portion 30 is formed on both the leading edge 32 and the trailing edge 33. This is because, in addition to the embodiment in which the long member 2 is inserted from left to right as shown in Figure 11, it is also possible to adopt an embodiment in which the long member 2 is inserted from right to left, which is not shown. However, it is also possible to adopt an embodiment in which the alignment step portion 30 of the main gauge plate 3 is formed only on the leading edge 32, or conversely, formed only on the trailing edge 33 (not shown).

[0040] Therefore, with the above-described alignment gauge, the leading end surface 21 of the elongated member 2 can be easily aligned by aligning it with the step 31 at a desired position on the alignment step 3 (FIGS. 9 to 11). For example, if the desired position of the hole 20 in the elongated member 2 is located at a desired distance b=40 mm from the leading end surface 21, as shown in FIG. 10, the leading end surface 21 of the elongated member 2 is aligned with the step 31 marked with the number a, labeled "40," on the alignment step 30, and the elongated member 2 is then positioned and fixed in place. Then, the handle 15 of the hole punching device 1 is simply pressed down, and the punch 10 is passed through the through hole 36 in the main gauge plate 3 (FIGS. 12 and 13). This allows the punching operation to accurately and reliably punch a hole 20 of, for example, φ=10 mm at the predetermined position c in the elongated member 2 (FIG. 14).

[0041] The above has been explained based on an embodiment, but it should be emphasized that the present invention is not limited to the illustrated examples, and includes the range of design modifications and application variations that would normally be made by a person skilled in the art, provided that they do not deviate from the technical concept.
