Abstract
The utility model discloses a cutting fixture of an inner ring arc section of an outlet guide vane of a compressor unit and relates to a cutting fixture. By the aid of the cutting fixture, the problems that no special cutting fixture is used in existing processing processes for inner ring arc sections and the processing precision is low are solved. A concave platform is arranged on a fixture body, the concave platform is matched with the outer circle dimension of the inner ring arc section to be processed, 36 pressing plates are arranged at the outer edge of the concave platform along the circumferential direction, 36 kidney-shaped grooves are evenly processed on the concave platform of the fixture body along the circumferential direction, one kidney-shaped groove is arranged between every two adjacent pressing plates, and the inner ring arc section to be processed is fixedly installed at a position of the concave platform of the fixture body through 36 pressing plates. The cutting fixture is used for processing the inner ring arc section to be processed.
Description
Technical field
The utility model relates to a kind of interior ring of exit guide blade sheet segmental arc cutting clamper of compressor unit.
Background technology
The every circle of ring segmental arc is made up of 36 sections segmental arcs in the exit guide blade sheet of compressor unit, and each segmental arc two ends is straight end face, and the end clearance is 0.5mm between segmental arc, and the chord length of above-mentioned 36 sections segmental arcs is 49 ± 0.05mm; In ring segmental arc process be to be annular workpieces with the turning of whole circle, utilize electric spark linear cutting machine that it is cut to 36 sections isometric interior ring segmental arcs again.Do not have special-purpose cutting clamper in the ring segmental arc process in existing, machining accuracy is low.
The utility model content
The utility model does not have special-purpose cutting clamper in the ring segmental arc process for solving in existing, the problem that machining accuracy is low, and then ring segmental arc cutting clamper in a kind of exit guide blade sheet of compressor unit is provided.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: ring segmental arc cutting clamper comprises clamp body and 36 pressing plates in the exit guide blade sheet of the compressor unit of the utility model; Be processed with concave station on the said clamp body; Said concave station matches with the excircle dimension of interior ring segmental arc to be processed; Said 36 pressing plates along the circumferential direction are provided with on the outer that is arranged on concave station; Along the circumferential direction be uniformly distributed with on the concave station of clamp body and be processed with 36 gains, be provided with a gain between two adjacent pressing plates, interior ring segmental arc to be processed is packed in the concave station place of clamp body through 36 pressing plates.
The beneficial effect of the utility model is: the interior ring segmental arc chord length that ring segmental arc cutting clamper will be processed in the exit guide blade sheet of the compressor unit of the utility model is controlled in 49 ± 0.03mm scope; Satisfy process requirements fully; Guaranteed the crudy of these parts, machining accuracy is high; The cutting clamper of the utility model is simple in structure, easy to use, processing effect is good.
Description of drawings
