Abstract

The invention discloses a clamp device for carrying out groove milling on a wheel disk of a gas turbine and relates to a clamp device. The invention solves the problem of difficulty in positioning and clamping in the machining process of the wheel disk of the existing gas turbine. A base (1), an indexing table (16), a clamp body (5) and a gland (6) of the clamp device are arranged sequentially from bottom to top. The base (1) and the indexing table (16) are relatively fixedly arranged through a plurality of pressure plates (14). The indexing table (16) and the clamp body (5) are relatively positioned through a plurality of positioning keys (13). The clamp body (5) and the gland (6) are relatively positioned through a plurality of positioning pins (12). The clamp body (5) and the gland (6) are relatively fixed through a double-thread screw (7) and a nut (8). A support frame (3) is arranged between the base (1) and the clamp body (5). The clamp body (5) and the support frame (3) are relatively positioned through a positioning inserted pin (4). The clamp device is suitable for the positioning and clamping of the wheel disks of various types of gas turbines.

Description

Technical field [0001] The invention relates to a clamp device, in particular to a clamp device used for slot milling of a gas turbine wheel disc. Background technique [0002] Gas turbine roulette wheel groove profile requires high precision, and there are the following technical difficulties: the roulette structure is complex and difficult to clamp; the roulette mechanism is thin, the rigidity is not good, and the processing is prone to vibration and deformation; the material of the roulette is high-speed alloy steel, which is processed Sex is not good. The roulette can be milled. The roulette is required to be connected and tightened with the indexing device through a clamp. Due to the high hardness of the product roulette, it has to withstand a large cutting force during processing. After the roulette is installed, it is required to have sufficient clamping force to clamp to ensure that the roulette does not vibrate during processing. In summary, the existing gas turbine w...
