Embodiment Construction
[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0046] like figure 1 As shown, the present invention provides a throat area control device for spot welding of turbine guide vanes, including a double-blade airfoil positioning fixture, a pre-weld measuring tool and a welding fixture, wherein the double-blade airfoil positioning fixture plays a role of quick clamping and The function of disassembling the double blade body; the pre-weld measuring tool cooperates with the double blade body positioning fixture to fine-tune the throat area of the blade; the welding fixture is used to weld the adjusted blade body and the edge plate to complete the qualified throat area turbine blades.
[0047] The double-leaf blade positioning fixture includes a compression screw 1, a rotating compression beam 2, a first compression block 3, an area adjustment block 4, a blade body positioning matching base 5, a circular permanen...

The invention provides a throat area control device and method in turbine guide vane electric welding process. Before a vane, firstly, the turbine guide vane is fixed through a dual-vane-body positioning clamp; then, the throat area on the welded turbine vane is calculated through a measuring tool for measuring before welding; and finally, by means of an area adjusting block, fine adjustment is performed on an angular direction positioning point of the vane body, and the throat area is adjusted qualified. An inductor external controller adopted by the device and method can display the area ofthe corresponding state in real time and transiently, and according to the corresponding changing, the area is controlled within a qualified range before welding and then is fixed. Due to the fact that the device is accurate in design, the requirement on experience of an operator is low. The device is successfully applied in actual welding, an original outdated welding method is replaced, and because the design concept is advanced, the device is easily popularized in turbine guide vane welding.
Description
technical field [0001] The invention is applied to combined welding of high vortex guide vanes, and is particularly suitable for a throat area control device and method in the spot welding process of turbine guide vanes. Background technique [0002] In the field of aero-engines, integrated fixed clamping welding is used for the welding of relatively complex high-pressure turbine guide vanes in China. The welding process does not control the turbine throat area that affects the important performance of aero-engines. The welding quality is limited by the casting wool, resulting in welding As a result, the throat area of the turbine blade is unqualified and scrapped. This technology has been solidified and applied for more than ten years, and has a huge impact on the production of aero-engines. In order to solve the disadvantages of this technology in practical application, it is urgent to innovate in technology and invent a method and control device to solve this problem. ...
