Description

  The present invention relates to a drilling jig for drilling a workpiece.

  When disposing of an automobile or the like, it is necessary to remove automobile components such as a motor. For example, Patent Document 1 describes a motor recovery device that enables a motor to be recovered by hooking a power device to an outer panel with the door of an automobile closed, and driving the power device to peel off the door outer panel. Has been. However, in the apparatus of Patent Document 1, it may actually take a lot of time to peel off the door outer panel.

On the other hand, for example, it is conceivable to make a hole in a vehicle body panel or the like of an automobile using a drilling device as described in Patent Document 2 and take out the internal components. However, in the drilling device described in Patent Document 2, it is necessary to provide a center drill at the center of the annular outer peripheral cutting edge, and the structure becomes complicated. In order to pierce a vehicle body panel with a drilling jig having a simple structure, it is necessary to adjust the position of the drill, which takes a long time.
JP 2003-31560 A

  In view of the above facts, an object of the present invention is to obtain a drilling jig capable of reliably drilling at a desired position of an object to be drilled in a short time.

  According to the first aspect of the present invention, a drill for drilling an object to be drilled, a holding member for holding the drill at a predetermined position with respect to the object to be drilled, and for pressing the drill against the object to be drilled It has a holding member and a vertical maintaining member that maintains the approaching direction of the drill to the drilled object in a direction perpendicular to the drilled object.

  Therefore, in this drilling jig, the drill can be held at a predetermined position with respect to the drilled object by the holding member. In this state, the drill can be pressed against the object to be drilled by the pressing member and can be drilled. Thus, since the drill is pressed against the object to be drilled in a predetermined state, the drill can be reliably drilled at a desired position in a short time.

  Moreover, the approaching direction of the drill to the drilled object is maintained in the vertical direction with respect to the drilled object by the vertical maintaining means. Therefore, it becomes possible to make the drill approach the object to be drilled with certainty by the pressing force of the pressing member, and it is possible to suppress the positional deviation of the drill during drilling.

  The invention according to claim 2 is characterized in that in the invention according to claim 1, there is provided a height adjusting means for adjusting the height of the drill with respect to the holding member.

  Thereby, in a state where the drill is held at a predetermined position with respect to the drilled object by the holding member, the height of the drill can be further adjusted to finely adjust the position.

  The holding member of the present invention may be configured to have an installation member installed on the installation surface as described in claim 3, or may be related to the drilled object as described in claim 4. The structure which has a mating engagement member may be sufficient. In the structure of Claim 3, since it is not necessary to engage a holding member with a to-be-punched object, it is excellent in workability | operativity. In the invention according to the fourth aspect, by engaging the engaging member with the drilled object, the drill can be aligned with the drilled object as a result.

  The invention according to claim 5 is the swing member according to any one of claims 1 to 4, wherein the vertical maintaining member holds the drill so as to be swingable with respect to the holding member. It is characterized by having.

  That is, the vertical maintaining member can be realized with a simple configuration in which the drill is rocked with respect to the holding member by the rocking member.

  Since the present invention has the above-described configuration, it is possible to reliably drill at a desired position of the drilled object in a short time.

  1 and 2 show a drilling jig 12 according to a first embodiment of the present invention. The use of the drilling jig 12 is not particularly limited. For example, when the automobile is discarded, the drilling jig 12 can be used at the time of drilling the vehicle body panel when removing the parts attached to the automobile. . That is, as will be described later, it is preferable when a vehicle body panel 90 (see FIGS. 5 and 6) is provided with a hole 92 (FIG. 6s award), and a vehicle component (for example, a motor 96) is removed from this hole. Used.

  The drilling jig 12 has an installation member 14 installed on the floor surface FL. The installation member 14 is formed in a rectangular frame shape, and a housing 16 is held in the center in a front view. A cylindrical air drill 18 is held at the center of the casing 16, and the panel 90 can be drilled by rotating the air drill 18 while moving the casing 16 toward the panel 90 in the direction of arrow A. An air hose 40 for supplying air for driving the drill is connected to the housing 16.

  As shown in FIG. 3, a female screw 20 that penetrates the upper side 14 </ b> U in the vertical direction is formed in the approximate center of the upper side 14 </ b> U of the installation member 14, and a support rod 22 is inserted into the female screw 20. . A male screw 24 that meshes with the female screw 20 is formed on the outer periphery of the support bar 22, and when a lifting handle 26 (see FIGS. 1 and 2) provided at the upper end of the support bar 22 is rotated, the support bar 22 is rotated. Moves in the longitudinal direction, that is, in the vertical direction.

  A cylindrical pipe 29 is attached in the vicinity of the lower end of the support bar 22, and the support bar 22 is divided into an upper part 22U and a lower part 22L. The pipe 29 connects the upper portion 22U and the lower portion 22L of the support rod 22 so as not to be separated, but the upper portion 22U is rotatable independently of the lower portion 22L.

  At the lower end of the support bar 22, the casing 16 is swingably held by a swing mechanism 28. The swing mechanism 28 includes a pin 30 that passes through the support bar 22 in parallel with the upper side 14 </ b> U, and both ends of the pin 30 protrude from the support bar 22. On the other hand, a pair of insertion plates 32 project from the upper surface of the housing 16, and the pins 30 pass through the insertion plates 32. The housing 16 is swingable about the pin 30 in the arrow SW direction.

  A pair of pressing handles 34 are provided on the side surface 16S of the housing 16. By pressing the pressing handle 34, the housing 16, that is, the air drill 18 can be brought close to the panel 90, and further, it can be strongly pressed against the panel 90.

  A wheel 36 is attached to the lower side 14 </ b> B of the installation member 14 on the side opposite to the approaching direction to the panel 90. The position (height) of the wheel 36 is determined such that when the installation member 14 is tilted in the direction of arrow B, the wheel 36 contacts the floor surface FL and rotates while supporting the drilling jig 12.

  In addition, a tray 38 is attached to the lower side 14B so as to be able to receive cutting powder that is generated during drilling.

  In order to pierce a vehicle body panel 90 as an object to be drilled using the drilling jig 12 of the first embodiment having such a configuration, first, as shown by an arrow B in FIG. 12 (installation member 14) is tilted and moved to the drilling position of panel 90. At this time, it can move easily by using the wheel 36.

  Next, the elevating handle 26 is turned, and the casing 16, that is, the air drill 18 is moved up and down to finely adjust the height so that the position of the air drill 18 coincides with the drilling position.

  Then, as shown in FIG. 5, while driving and rotating the air drill 18, the air drill 18 is pressed against the panel 90 by the pressing handle 34 (see FIGS. 1 and 2), and a hole 92 (see FIG. 6) is formed in the panel 90. Wear. At this time, since the casing 16 swings around the pin 30, the moving direction of the air drill 18 can be maintained and pressed in a direction close to the vertical direction with respect to the panel 90. Depending on the position and inclination of the panel 90, the movement direction of the air drill 18 may not be perpendicular to the panel 90 by simply swinging the housing 16. What is necessary is just to adjust the whole position (especially distance with respect to the panel 90) appropriately.

  As described above, in the drilling jig 12 of this embodiment, the installation member 14 can hold the air drill 18 at a predetermined position with respect to the panel 90 via the housing 16. In this state, a pressing force can be applied to the air drill 18 using the pressing handle 34 so that the air drill 18 is strongly pressed against the panel 90 and can be reliably pierced at a desired position. In addition, since the air drill 18 can be swung around the pin 30 so that the approaching direction of the air drill 18 to the panel 90 can be maintained in a direction perpendicular to the panel 90, the position of the air drill 18 during drilling can be prevented. Eighteen punching forces can be reliably applied to the panel 90. As described above, drilling can be performed in a short time.

  In addition, after drilling, as shown in FIG. 6, the bar 94 etc. can be inserted from the hole 92, and the motor 96 etc. can be peeled off.

  7 and 8 show a drilling jig 52 according to a second embodiment of the present invention. Hereinafter, in 2nd Embodiment, the same code | symbol is attached | subjected about the same component, member, etc. as 1st Embodiment, and the detailed description is abbreviate | omitted.

  In the second embodiment, the housing 16 having the same air drill 18 as in the first embodiment is provided, but the installation member 14 of the first embodiment is not provided, and instead of this, the housing is provided. A pair of hooks 54 are provided on both side surfaces 16 </ b> S of 16. The hook 54 extends upward from the side surface 16S of the housing 16, and the upper end portion is curved in a substantially semicircular shape in the same direction as the blade edge of the air drill 18 as shown in FIG. Has been. As shown in FIG. 10, the curved portion 54B has a shape that can be hooked on the upper edge 90E of the vehicle body panel 90 (for example, between the outer panel 90A and the inner panel 90B).

  The lower end of the hook 54 is connected to the housing 16 by a rocking lock mechanism 56. As shown in detail in FIG. 9, the swing lock mechanism 56 has a bracket 58 that accommodates the vicinity of the lower end of the hook 54, and a portion between the side surface 16 </ b> S of the housing 16 and the hook 54 is a sawtooth plate 60. It is said that. A pin 62 protrudes from the side surface 16 </ b> S, and the pin 62 is inserted into the insertion hole 64 near the lower end of the sawtooth plate 60. The casing 16 can swing around the pin 62 in the arrow SW direction (see FIG. 8).

  A sawtooth 66 is formed at a position above the insertion hole 64 of the sawtooth plate 60 so as to face the hook 54, and a sawtooth 68 is formed on the hook 54 correspondingly. The saw teeth 66 and 68 engage with the downward movement of the housing 16 with respect to the hook 54 to exert a large resistance, but the movement in the opposite direction, that is, the upward movement of the housing 16 with respect to the hook 54 is allowed. ing.

  A fixing screw 70 is screwed onto the surface of the bracket 58 opposite to the saw blade plate 60 so that the hook 54 can be clamped and fixed between the tip of the fixing screw 70 and the saw blade plate 60. When the fixing screw 70 is loosened, this fixing is also released, and the housing 16 can move up and down with respect to the hook 54.

  In order to pierce the panel 90 using the piercing jig 52 of the second embodiment configured as described above, first, as shown in FIG. Hook to 90E and fix.

  Next, the fixing screw 70 is loosened, the vertical position of the housing 16 with respect to the hook 54 is adjusted, and the position of the drill is finely adjusted to match the desired drilling position.

  Thereafter, as in the first embodiment, while the air drill 18 is driven and rotated, the air drill 18 is pressed against the panel 90 by the pressing handle 34 to make a hole in the panel 90 (see FIG. 6 of the first embodiment). At this time, the housing 16 swings around the pin 62 in the direction of arrow SW shown in FIG. 6, so that the moving direction of the air drill 18 can be maintained and pressed in a direction close to the direction perpendicular to the panel 90.

  As described above, in the drilling jig 52 of the second embodiment, the air drill 18 can be held at a predetermined position with respect to the panel 90 via the housing 16 by the hook 54. In this state, a pressing force can be applied to the air drill 18 using the pressing handle 34 so that the air drill 18 is strongly pressed against the panel 90 and can be reliably pierced at a desired position. In addition, since the air drill 18 can be swung around the pin 62 so that the approach direction of the air drill 18 to the panel 90 can be maintained perpendicular to the panel 90, the position of the air drill 18 during drilling can be prevented. Eighteen punching forces can be reliably applied to the panel 90. As described above, drilling can be performed in a short time.

  In the second embodiment, the hook 54 is used as the engagement member of the present invention. However, the engagement member is not limited to this, and in short, a part of the punching jig 52 (the casing 16) is attached to the panel 90. It only needs to be engaged and fixed. For example, a clip or the like is also included in the engagement member of the present invention.
