Description

The present invention relates to a drilling jig with a box-shaped housing having an interior and at least one drilling channel passing through the housing, which has an opening to the interior of the housing, and to a method for mounting a fitting with a drilling jig. In the DE 20 2007 002 845 U1 A drilling template is disclosed in which several openings are formed through which a cutting tool can be inserted. Each opening has a channel with an opening, allowing air to be extracted from the openings via an attached extraction system, thus enabling the extraction of chips through the drilling template. The use of the drilling template therefore requires interaction with the extraction system, which is complex during assembly. Furthermore, there is no movable stop to align the drilling template relative to other components. In the US 9,199,314 B1 A drilling template is disclosed in which a stop element is movable relative to a U-shaped component. This allows the stop element to be aligned relative to the U-shaped component, and a machining tool can be inserted through corresponding openings. Chips generated during machining are not collected, which can be disadvantageous, especially when installing cooling units in cabinet furniture, if chips strike elastic seals and contaminate or damage them, impairing their function. It is therefore an object of the present invention to provide an improved drilling jig and a method for mounting a fitting in which the disadvantages described above can be avoided. The drilling jig according to the invention comprises a box-shaped housing with an interior and at least one bore channel extending through the housing, which has an opening to the interior of the housing. At least one stop element is movably mounted on the housing. The housing can be aligned relative to another element, for example, a furniture carcass, by means of the at least one stop element, so that the housing can then be positioned at a predetermined distance from another point on the furniture carcass. The movable stop element can thus be used to align the housing. The housing includes an interior in which chips generated during machining can be collected, and the chips can be discharged into the housing through the opening in the at least one bore channel. Chip collection can occur without a dust extraction device, although such a device can be provided optionally. Preferably, the at least one bore channel is tubular and includes at least one pipe stub that projects at least partially into the interior of the housing. Preferably, the tube channel has two pipe stubs spaced apart at their free ends, creating an annular opening between them. During machining, for example drilling, the chip can then be moved axially along the drill bit until it reaches the annular opening in the bore channel, at which point the chip can be discharged into the interior of the housing. This prevents environmental contamination during assembly when using the drilling jig. The housing preferably has at least one discharge opening, optionally closable, which can be used as a chip outlet. For precise alignment of the housing, the at least one stop element can be clamped or snapped into place on the housing. For this purpose, the stop element can have a rib that can be inserted into a receptacle in the housing. The receptacle preferably extends at least partially into the interior of the housing, and more preferably penetrates the interior. The receptacle for the rib in the housing is closed off from the interior of the housing, which is intended for chip collection, to prevent chips from escaping through the receptacle. Optionally, several ribs or guide elements of the stop element can be inserted into the housing, or at least one rib can be guided on the outside of the housing, for example, via a groove or a guide rib. The rib on the stop element preferably projects substantially perpendicular to an axial direction of the at least one bore channel in the housing and can be inserted into the housing accordingly. For easy fixation of the stop element, the housing can have at least one flexible locking tab, which is preferably integral and can be locked onto a profiled section of the tab. The profiled section can, for example, be designed as teeth or knurling. It is also possible for the profiled section to be... The housing and the flexible locking tab are arranged on the stop element. The profile allows the stop element to be adjusted within a range of 2 mm to 10 mm, preferably between 4 mm and 8 mm. To ensure the stop element is securely attached to the housing, the profiled element features a raised detent that rests against the flexible detent bar but cannot be overcome in one direction. The detent has a chamfer on one side to allow the flexible detent bar to overcome it during initial assembly of the stop element to the housing. The raised detent acts as a safeguard against the detent bar of the stop element being pulled out. Th
