Abstract
A mobile power tool operating assembly for performing material treatment operations, such as drilling, has permanent magnet means to mount the power tool on a ferromagnetic workpiece, and release means to permit release of the magnet means for repositioning of the tool. The release means comprises a screw threaded jack which tilts the assembly so as to overcome the magnetic attraction. The tool can then be repositioned and lowered to its normal working attitude.
Claims16
A mobile power tool mounting assembly, for mounting a power tool to perform material treatment operations, for example drilling, at selected locations on a workpiece, the mounting assembly comprising:
- a) a support structure;
- b) mounting means for mounting a power tool on said support structure;
- c) permanent magnet means mounted on said support structure for holding said structure and said tool at a selected location on said workpiece or to an associated ferro-magnetic plate or the like;
- and
- d) release means to permit release of said magnetic means from said workpiece or mounting plate to permit repositioning of said tool relative thereto;
- characterized in that
- e) said release means comprises thrust means arranged to act between said workpiece or mounting plate and said support structure at a location offset from the central region of said magnet means and actuable to exert a thrust sufficient to overcome the attraction exerted by said magnet means so as to tilt said magnetic means relative to said workpiece.
A mobile power tool mounting assembly having permanent magnet means for mounting a power tool on a workpiece, and release means therefore, said release means comprising thrust means to tilt the magnetic means relative to the workpiece, characterized in that said release means comprising thrust means arranged to act between said workpiece or a mounting plate and a support structure for the power tool, at a location offset from the central region of said magnet means.
A method of mounting a power tool for performing material treatment operations at selected locations on a workpiece, the method comprising the steps of providing a mobile power tool mounting assembly having permanent magnet means for mounting a power tool on a workpiece, and release means therefore, said release means further including thrust means to tilt the magnetic means relative to the workpiece, wherein said thrust means is arranged to act between the workpiece or a mounting plate and a support structure for the power tool at a location offset from the central region of said magnet means, and the step of causing said thrust means to act between said workpiece and said assembly so as to exert a thrust sufficient to overcome the attraction exerted by said permanent magnet means so as to tilt said assembly relative to said workpiece and enable said assembly to be re-positioned.
A method according to claim 13 characterized by the step of causing said thrust means to permit said power tool to return to its non-tilted operating attitude.
