Problems solved by technology

During the process, the wind power stator and rotor need to be hoisted, flipped and clamped multiple times, resulting in long processing hours, low production efficiency, and uncontrollable deformation. The window area can only be processed by side milling, which is time-consuming and laborious, and the accuracy cannot be guaranteed.

Abstract

The invention relates to a superlarge-diameter rotation body tool fixture. The superlarge-diameter rotation body tool fixture comprises a rotary workbench and a plurality of supporting devices and a benchmark device which are slidably arranged on the rotary workbench, some or all of the plurality of supporting devices are provided with fixtures, and the supporting devices and the fixtures form aninternal-external dual supporting and inwards clamping superlarge-diameter rotation body clamping mechanism. The superlarge-diameter rotation body deformation risk is reduced on the premise that the clamping stability is guaranteed; double-row staggered clamping tooth sliding ways are adopted and cooperate with locking keys on the two sides of a bottom plate, and the higher positioning precision of the supporting devices on tracks is achieved; and supporting groups with the adjustable height are adopted, workpieces are allowed to be separated from supporting of the rotary workbench face, therefore, the increased machining space is obtained, and the workpiece turning number is decreased.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a fixture for mechanical processing, and more specifically to a tooling fixture for a super large-diameter rotary workpiece. Background technique [0002] With the development of large-scale wind turbines, the size of its components also continues to increase. Wind power stator and rotor is one of the main core components of wind power generators, which is a type of rotary casting; at present, the most common wind power generator stator and rotor have an external dimension of about Φ6.9m x 1.2m, and a blank weight of about 40 tons; Compared with the overall size of the stator and rotor, its wall thickness is relatively thin, and it is easy to deform during processing; in addition, the number of holes processed in the wind power stator and rotor is large and the processing requirements are high. This makes it difficult to lift, turn over, and poor positioning accuracy in the ...
