Abstract:
The invention relates to a parallel positioning mechanism, especially for machining and/or manipulation and/or measuring, consisting of a platform for the carrying and/or manipulation with, for instance, a tool, a workpiece, a measuring device or the like, wherein the platform is connected with the machine frame by means of at least one positioning arm, characterised in that the platform (3) is joint-connected with at least one sliding guide (4) via at least three rotatable joints (11) of which at least two are arranged on a positioning arm (6) for the connection with the sliding guide (4), wherein the axes of rotation of the rotatable joints are mutually parallel. The direct connection may be replaced by a plurality of positioning arms (6), in which case the connection of the platform (3) with the sliding guide(s) (4) is achieved by means of at least four positioning arms (6).
Abstract:
The invention concerns a method of creating metal components using the deposition of material, where a weld deposit with the size of 2 to 200 mm3/s is created, and then cooled to a temperature of 20 to 90 °C and cleaned; after that the weld deposit is machined to the shape of the base with 1 to 3 defined contact surfaces for the next deposit and, after additional cleaning and drying, another weld deposit is created with the size of 2 to 200 mm 3 /s. It also concerns an apparatus for implementing this method, where at least three motion axes (10), (11) and (14), a head stock and a spindle (OP11 and OP12) with a tool (18) are integrated in one closed, ventilated area in the apparatus, and other technology units are connected to the body of the head stock, selected from the group of welding head (OP01), continuous cooling unit (OP02, OP03, OP04, OP05, OP06), weld deposit cleaning unit (OP09 and OP10), cleaning and drying unit (OP13 and OP14) and temperature control unit (OP89 and OP99), and the table (1) is equipped with internal cooling OP08.
