Abstract
Equipment for making a hole or cavity formation in a curved or planar wall element, and for cutting out a disc-shaped piece of material fitting the hole or cavity formation, includes a frame with devices for fixing it on the wall element, and a carriage displaceably mounted in a first linear direction. A slide is mounted to be displaceable in a direction perpendicular to the first linear direction and carries a tool unit. The carriage has wheel sets which are biased against the wall element. The wheel sets are pivotable and displaceably mounted on a respective guide slide, which is mounted to be displaceable in the first linear direction.
Claims26
Apparatus for cutting one of a hole and a cavity in a wall element having a surface, the wall element being one of curved and planar, said apparatus comprising:
- a frame;
- at least one fixing device mounted on said frame, said at least one fixing device being configured for fixing said frame to the wall element;
- at least one carriage displaceably mounted in said frame;
- a plurality of support devices connected to said at least one carriage, said support devices including one of a plurality of slide elements and a plurality of roller elements, said one of a plurality of slide elements and a plurality of roller elements being configured for contacting the surface of the wall element and for facilitating movement of said at least one carriage in a first linear direction;
- a plurality of rectilinear, parallel first guide devices fixed in said frame, each said first guide device being configured for guiding a respective said support device in said first linear direction;
- a plurality of rectilinear, parallel second guide devices interconnecting said support devices;
- a slide displaceably mounted on said second guide devices, said slide being displaceable in a second linear direction substantially perpendicular to said first linear direction;
- a tool unit carried by said slide, said tool unit being configured for cutting the one of a hole and a cavity in the wall element;
- a guide slide displaceably mounted on a selected cooperating said first guide device, said guide slide having a pivot axis substantially parallel to said second guide devices, said guide slide being pivotally connected to a respective said support device about said pivot axis, said selected support device being displaceably mounted to said guide slide such that said selected support device is displaceable in a direction substantially perpendicular to the surface of the wall element;
- and
- a plurality of biasing devices, each said biasing device being configured for biasing said one of a plurality of slide elements and a plurality of roller elements of a respective said support device against the surface of the wall element.
Apparatus for cutting out a disc-shaped piece of material from one of a web of material and a sheet of material, said apparatus comprising:
- a frame configured to be fixed to a solid supporting surface;
- at least one carriage displaceably mounted in said frame;
- a plurality of support devices connected to said at least one carriage, said support devices including one of a plurality of slide elements and a plurality of roller elements, said one of a plurality of slide elements and a plurality of roller elements being configured for contacting a profile surface and for facilitating movement of said at least one carriage in a first linear direction;
- a plurality of rectilinear, parallel first guide devices fixed in said frame, each said first guide device being configured for guiding a respective said support device in said first linear direction;
- a plurality of rectilinear, parallel second guide devices interconnecting said support devices;
- a slide displaceably mounted on said second guide devices, said slide being displaceable in a second linear direction substantially perpendicular to said first linear direction;
- a tool unit carried by said slide, said tool unit being configured for cutting out the disc-shaped piece of material from the one of a web of material and a sheet of material;
- a guide slide displaceably mounted on a selected cooperating said first guide device, said guide slide having a pivot axis substantially parallel to said second guide devices, said guide slide being pivotally connected to a respective said support device about said pivot axis, said selected support device being displaceably mounted to said guide slide such that said selected support device is displaceable in a direction substantially perpendicular to the profile surface;
- and
- a plurality of biasing devices, each said biasing device being configured for biasing said one of a plurality of slide elements and a plurality of roller elements of a respective said support device against the profile surface.
