Spacing arrangement designed for work operations such as fixed welding of workpieces and containing at least one axially adjustable spacing element 1, which can be locked in the adjusted position or released from it, for placement between two workpieces 31, 32 or one workpiece and a fixture, etc. The arrangement can also be provided with or designed to interact with elements 33, 34 for positioning of the spacing element 1 relative to the workpiece or pieces and clamping of the latter against the spacing element. A tubular element, such as a piston 5, can be clamped by a rotary axle 3 in a position projecting relative to a housing 2 or be released to enable a retracted position. The arrangement can be provided with an adjustment element 4 functioning as an adjustable extension piece of the housing 2 for fine-setting of the spacing distance, which moreover can be regulated by connection of extension pieces 25-27 to the adjusting element. <IMAGE> |
