DESCRIPTION:
BRIEF SUMMARY
The invention relates to a device for receiving tools.
A device of this type is described in the EP-311 789 B1 or in the U.S. Pat. No. 5,048,700.
The present invention is concerned with the method for manufacturing the receiving device in such a way that, on the one hand, a precise gauge is created for the tools inserted therein and, on the other hand, the expense of manufacturing it is kept as low as possible, so that the overall device can be manufactured economically.
To accomplish this task, on which the invention is based, it is proposed that the housing be manufactured in a suitable way in the shape of a shell with a wall of uniform or variable thickness, e.g. by injection molding a plastic, in such a way that this upper section of the housing is closed by a base. The housing has receiving holes for receiving the tools, e.g. a drill. Several receiving holes per measurement size can also be arranged here arbitrarily above one another and/or next to one another. The upper section of the housing and its base have outer dimensions which correspond to those of the finished receiving device.
The receiving holes preferably are extended by threaded bushes, which can be designed as an independent component. Steadying brackets for receiving and centering the threaded bushes can here be provided on the base plate, so that the individual components are automatically centered when they are inserted into one another. Inside the threaded bushes, adjustment screws can be provided, which form the base of the particular receiving hole and which can be screwed up or down as needed, depending on the length of the tool being received, e.g. a drill, a plug gauge, or the like. These adjustment screws can be operated either by a hex wrench or by a standard screwdriver or also by the drill itself.
The actual gauges can be foraged by pins which can be inserted into the recess. However, round contact bodies have the disadvantage of offering only a relatively small measurement surface since the curvature of the pin really makes available only the very small tangent surface as the actual measurement surface.
The invention furthermore proposes that the actual gauges be formed by plates which can be inserted into the recess. In this case, recesses are provided in these plates so as to form the two mutually opposite measurement surfaces. Here it is possible to design each of these gauges as a plate with a U-shaped recess, or to design the gauges as plates which are cut out U-shaped at the positions that coincide with the fine measurement channels, so that the gauges are connected together, and it is only necessary to insert a plate for each measurement size of several channels. In this case, the gauges suitably are manufactured of flat stock, preferably of metal. Furthermore, the plates or only the edges of the U-shaped cut-outs, which form the actual gauges, can also be hardened.
Another advantage of designing the gauges as plates is that the gauges can be clamped into packages, so that several of these plates can be finish-processed at the same time to the particular dimensions that are intended. At the same time, a coding to classify the plate can be provided on it, a reciprocal coding being provided on the base plate, on the housing, or on another structural part. The edges of the actual gauges are then inserted into the recesses situated in the upper section of the housing.
The individual threaded bushes preferably consist of hemi-shells, which are then joined for actual use. In this connection, it is therefore proposed that each hemi-shell have half of the thread on its inside, the two hemi-shells then being joined by suitable means. The hemi-shells are securely held together by appropriate means, such as clips, glue, rivets, etc. At the same time, their upper and/or lower ends are fastened on the base and/or in the upper section of the housing.
The invention also provides that, after all the structural parts have been. inserted, the upper section of the housing be wholly or partly filled with suitable materials, so that the
