Abstract
At least one brush rotatable about an axis parallel to the plate (1) and to a plane containing a row of bearing surfaces (4) of openings (2) of the plate (1), is moved along a rectilinear path (5a, 5b, 5c) parallel to the plane of the bearing surfaces (4) of the openings (2) of the row of the plate (1). Preferably, the device comprises a brushing unit mounted at the end of an articulated arm of a robot permitting the movement of the brushing unit in succession along rectilinear paths (5a, 5b, 5c) constituting several groups in which the paths are parallel to the same direction.
Claims8
A process for deburring and chamfering edges of through openings having axes extending through a plate for maintaining a bundle of tubes arranged in a regular network, each of said through openings comprising at least three bearing surfaces for a respective tube of said bundle, said bearing surfaces of all of said through openings of said plate being disposed in planes perpendicular to faces of said plate and parallel to said axes of said through openings, a group of said bearing surfaces of a rectilinear row of said openings of said network being disposed in each one of said planes in an aligned manner in a rectilinear direction, and said planes and said rectilinear rows of openings constituting at least a first group of parallel planes and of rows parallel to a first direction and a second group of parallel planes and of rows parallel to a second direction, said process comprising the steps of
- (a) moving at least one brush which is rotatable about an axis parallel to said plate so as to cause it to sweep across at least one face of said plate;
- (b) deburring and chamfering said edges of said through openings in successive rectilinear rows;
- (c) for each of said rectilinear rows, moving said at least one brush with said axis of rotation thereof parallel to the planes of said first group of planes, in a rectilinear path of a first group of paths parallel to said planes of said first group of planes;
- and
- (d) for each of said rectilinears rows of said second group of rows, moving said at least one brush with said axis of rotation thereof parallel to the planes of said second group of planes, in a rectilinear path of a second group of rectilinear paths parallel to said planes of said second group of planes.
