Definitions
- the invention concerns an electric grinding machine which is especially intended for deburring, i.e. grinding burrs of e.g. metal constructions etc.
- the present invention aims to present a grinding machine which has improved capabilities with respect to the exhaust efficiency of the particles which release during deburring and with respect to the ergonomics and manoeuvrability of the machine.
- the grinding machine - comprising a motor part, a transmission part, a drive spindle, a connection part for mounting a grinding disk to the drive spindle and a safety and exhaust cover which partly covers the grinding disk when mounted to the drive spindle, which cover is mounted to a bearing shaft which surrounds said drive spindle - according to the invention comprises a flexible interface between said cover and said bearing shaft, enabling that the cover is movable -with respect to the shaft and - in consequence - with respect to the rest of the whole machine.
- the flexible interface between the machine's cover and bearing shaft is preferably arranged in a way that the cover is movable along the axis of the bearing shaft.
- the flexible interface between the machine's cover and bearing shaft is, moreover, arranged in such way that the cover is pivotally movable around the axis of the bearing shaft.
- a preferred embodiment of the flexible interface comprises an O-ring of a flexible material between the cover and the bearing shaft, which O-ring may be made of a natural or synthetic rubber or elastomer.
- the grinding machine shown in figure 1 comprises a motor part 1, a square, block shaped transmission part 2, a drive spindle (not shown explicitly), including a connection part for mounting a grinding disk 3 to the drive spindle and a bearing shaft 4 which surrounds said drive spindle.
- the grinding machine may be provided with a detachable cover 5 which - when mounted to the bearing shaft surrounding the drive spindle - partly covers the grinding disk for personal safety and forming an exhaust nozzle with which can be connected, via a connection part 6 with a exhaust system (not shown).
- the cover 5 comprises an mounting part 7 the inside shape and dimensions of which are compatible with the outside shape and dimensions of the bearing shaft 4.
- a flexible interface is provided which is arranged in a way that the cover is movable with respect to said bearing shaft.
- the flexible interface is formed by an O-ring 8 between the mounting part 7 of the cover 5 and the bearing shaft 4, made of a natural or synthetic rubber or elastomer.
- the O-ring may be accommodated in a groove (not explicitly shown) in the outside of the bearing shaft 4.
- a (shallow) groove 9 at the inside of the mounting part 7 may be provided to prevent that the cover 5 may slide off from the bearing shaft 4.
- the mounting part 7 can be clamped around the bearing shaft 4 by means of any kind of (releasable) clamp coupling (not shown).
- the grinding machine's cover 5 and bearing shaft being arranged - by means of the "interfacing" O-ring 8 - that the cover is movable along the axis of the bearing shaft - and thus with respect to the grinding disk -, which in practice means a substantial improvement in operational comfort and efficiency, as well as in exhaust efficiency, thanks to improved adaptation of the plain of the cover to the plain and/or shape of the construction to be deburred.
- the grinding disk 3 can be brought closer to the construction to be deburred, viz. with less hindrance of the cover 5 thank to its flexibility, a greater deburring efficiency can be obtained.
- the comfort and efficiency is additionally improved thanks to the ability provided by the configuration discussed here that, moreover, the mounting part 7 of the cover 5 is pivotal around the axis of the bearing shaft 4 which is additionally enabled by the flexible O-ring interface 8 between the mounting part 7 and the bearing shaft 4.
