Example Embodiment
[0033] Example 1
[0034] For a bearing ball-and-socket swing nozzle housing, the inner spherical diameter of the fixed nozzle housing is SR130 mm±0.05mm, and the fixed nozzle housing 1 and movable nozzle housing 2 spherical unilateral clearance value requires 0.1mm~0.2mm , The center axis of the fixed nozzle shell sphere, the mounting hole in the swing shaft, the center axis of the movable nozzle shell sphere and the outer mounting hole of the swing shaft coincide, and the position degree does not exceed ±0.03mm.
[0035] The combined milling method of bearing ball and socket swing nozzle shell includes the following steps:
[0036] 1) Installation and machining of fixed nozzle shell: such as Figure 5 As shown, the flange 11 of the fixed nozzle housing blank 10 is downwardly fixed on the fixture, connected to the fixture, and 12 M15 screws are tightened symmetrically to ensure a firm connection. The fixture is provided with a support ring 7 and a support ring 7 The inner wall has ...
