Hydraulic supporting clamp for rotor processing

Abstract

The invention discloses a hydraulic supporting clamp for rotor processing. The hydraulic supporting clamp for rotor processing comprises a liner (2), liquid plastic (3), a first screw (4), a plunger (5), a positioning sleeve (6), a liner (7), a retaining sleeve (8), a composite cushion ring (9) and a second screw (10), wherein the positioning sleeve (6) is a main body structure part and is composed of a small end ring and a large end ring; the small end ring and the large end ring are coaxially integrated; the inner side of the large end ring is matched with a processing equipment supporting structure; and an outer side groove of the small end ring supports the liner (7). The hydraulic supporting clamp for rotor processing is simple in structure, high in practicability, short in design and manufacturing period, low in cost, convenient to use and easy to operate, can accurately position a machine element, lowers auxiliary cost brought by a conventional tool and improves the assembly efficiency.

Description

technical field [0001] The invention relates to the technical field of structural design and application of machining fixtures, and in particular provides a hydraulic support fixture for rotor machining. Background technique [0002] A certain size of the high-pressure turbine rotor of an engine requires component processing. The transfer tooling fit between the parts and the machine tool is an interference fit. The traditional tooling design needs to cool or heat the parts before assembling. After assembly, the room temperature needs to be restored, which has a long assembly cycle and waste of energy. [0003] The rear shaft structure of the high-vortex rotor is an internal support structure, and the support reference is located in the inner cavity of the rear shaft. It is not a general outer circular clamping structure, and it is difficult to fix it on the processing equipment. Therefore, a special support fixture is proposed, and the rear shaft inner cavity is used as the...

[0002] A certain size of the high-pressure turbine rotor of an engine requires component processing. The transfer tooling fit between the parts and the machine tool is an interference fit. The traditional tooling design needs to cool or heat the parts before assembling. After assembly, the room temperature needs to be restored, which has a long assembly cycle and waste of energy

[0003] The rear shaft structure of the high-vortex rotor is an internal support structure, and the support reference is located in the inner cavity of the rear shaft. It is not a general outer circular clamping structure, and it is difficult to fix it on the processing equipment. Therefore, a special support fixture is proposed, and the rear shaft inner cavity is used as the positioning reference. However, due to the positioning and assembly relationship between the fixture and the inner cavity of the rear axle, an interference fit is required. In addition to the long assembly and disassembly preparation period, the general cold and hot assembly fixtures also require special heating or cooling solutions and special disassembly process equipment. Increased requirements, etc., the process is complex and difficult
