Description
Technical Field
[0001] The utility model belongs to the technical field of turbine tile positioning fixtures, and in particular relates to a full-circumferential positioning tool fixture for turbine tiles. Background Art
[0002] In the production process of gas turbine turbine equipment, turbine blades are important parts. They are made of high-temperature alloys. Turbine blades are located near the nozzle of the gas turbine, and the stability of the gas turbine is relatively high. In the production and processing of turbine blades, it is often necessary to clamp and position the turbine blades. The existing positioning fixture of turbine blades is to clamp a single blade through the existing claw equipment, and then carry out subsequent production and processing. The existing clamping operation of a single turbine blade has low production efficiency and cannot meet the requirements of mass production.
[0003] The existing clamping equipment uses a claw fixing method during the clamping process of the turbine blade, which often fails to properly position the parts. Since the turbine blade has a curvature, the clamping force of the claw is often too large, causing damage to the turbine blade. However, if the clamping force of the claw is too small, the fixation is not firm and there is shaking, which ultimately affects the quality of subsequent processing of the turbine blade. At the same time, in the traditional method of using claws, only a few points on the outer surface of the part are subjected to force. During the long process of part processing, the turbine blade is often deformed and damaged due to the concentrated force. Traditional positioning and clamping equipment often has relatively fixed locations and cannot complete the clamping of multiple parts of the part. Utility Model Content
