Abstract
By, according to the invention, designing a surface treatment tool with a grinding head (16, 17) with cylindrical rollers (18), so that the tool (16, 17, 18) is balanced by weight because the tool's centre of gravity is close to the tool's surface treatment area, the tool (18) will automatically adjust according to the surface (25) of the treated workpiece, regardless of the level of the surface. Hereby is achieved a previously unknown simple way to surface treat, be it flat and curved workpiece surfaces alike. Furthermore, the tool (16,17,18) is balanced by weight so that treatment pressure can be adjusted according to need.
Claims4
A surface treatment tool for treatment of workpiece surfaces (25), which tool comprises a rotating tool head (13,14,15,16) which is radially mounted several rotating tools (17,18), which rotating tools (17,18) include cylindrical, cutting or grinding rollers (18), wherein the tool head (13,14,15,16) is fitted with opposite bearings (12) being rotatably mounted to ends (10,11) of a suspension thereby providing said tool head (13,14,15,16) with an axis (20) of rotation, wherein the suspension is rotatably mounted to a fitting bearing (9) thereby providing the suspension with an axis (21) of rotation which is perpendicular on the axis (20) of rotation of the tool head (13,14,15,16), wherein the fitting bearing (9) is rotatably mounted to a fitting bracket (8) that is tiltable about a tilt axis (22) perpendicular to the axis (21) of the rotation of the suspension, wherein the ends (10,11) of said suspension are rotatably mounted to said opposite bearings (12) at a position below the fitting bracket (8) such that the axis of rotation (20) of the tool head is positioned at a level below the axis of rotation (21) of the suspension (10, 11).
