Background
The spoke type casing part needs to weld a spoke plate on an outer ring to form an inner ring characteristic, the spoke plate is large in overhang length, and the size processing is carried out on the split inner ring characteristic after welding. The welded parts are deformed, the height difference of the inner rings is inconsistent, the structural rigidity of the parts is poor, the machining is difficult, and the dimension of the parts in a free state after the machining is difficult to ensure. Therefore, the method for processing the split type features is urgent.
Disclosure of Invention
The invention aims to provide a technical scheme capable of solving the deformation problem in the process of processing or after processing of a spoke plate part.
The invention specifically provides a processing scheme of a part split type characteristic, and the structure of a part 3 to be processed is shown in fig. 5, wherein a spoke plate 302 is welded on the inner side surface of an outer ring 301 to form a split type inner ring 303. The processing stability of the inner ring is poor due to the excessive overhang of the web 302.
The center of the disc-shaped clamp 1 is provided with an adjustable auxiliary supporting component 2, and the auxiliary supporting component 2 can move along the vertical direction and is locked by a locking bolt 102 fixed on a bracket 101.
The inner ring gap 304 is filled by a feeler gauge between the inner ring of the valve halves. And the inner ring clearance is avoided during processing, and the processing stability is improved.
The part 3 to be machined is placed on the fixture 1, all the auxiliary supporting assemblies 2 are adjusted to be lower than an inner ring clamping plane of the part 3 to be machined, the end face of the part inner ring 303 is pressed, the adjustable supporting height is adjusted, and meanwhile, the inner ring pressing plate 103 is pressed until the value of a measuring table is unchanged. Each web 302 is clamped.
The cover 4 is used for covering the radial plate 302, so that the phenomenon that the radial plate is disturbed by air flow due to rotation of parts during machining is avoided, and the stability of the planeness of the split structure after machining is guaranteed after machining. The covering may be a rubber or other material. In particular use, the covering is a rubber.
According to the invention, each radial plate is supported and clamped through the adjustable auxiliary support assembly, so that the radial plates, the outer ring and the inner ring are sufficiently supported, the problem of inconsistent height difference of the inner ring caused by deformation in the process of machining parts or after machining is prevented, and the integral rigidity of the part structure is improved.
