Problems solved by technology
Therefore, in the past, in order to obtain better processing quality in five-axis rotary machining, the only way to eliminate the influence of blade deformation on machining is to reduce the cutting amount and tool feed rate, or modify the shape, but this is still It cannot fully meet the size requirements of the drawing, and also seriously affects the milling efficiency of the blade

The invention provides a locating and clamping device for machining a bacterial type blade shroud, which can effectively reduce influence on the location degree of the blade shroud due to shaped wire deformation, ensure the machining quality of the blade shroud and increase the machining efficiency. The locating and clamping device comprises a clamping base plate, wherein one end part of the clamping base plate is provided with a blade root locating seat. The locating and clamping device is characterized in that the other end of the clamping base plate is provided with a blade shroud compression seat, the oblique extending end of the blade shroud compression seat is provided with a back arc compression block, and the vertical end of the blade shroud compression seat is provided with a blade shroud hinge pressing plate of which the inner side is provided with an inner arc compression block; the blade shroud hinge pressing plate is provided with a trailing edge compression screw; and the blade shroud compression seat is internally provided with a leading edge ejector block.
Description
technical field [0001] The invention relates to the technical field of blade processing tooling, in particular to a positioning and clamping device for processing fungal blade crowns. Background technique [0002] Generally, the processing of the crown of the fungus blade is mainly realized by five-axis rotary milling. The crown is processed and formed at the same time as the milling of the steam channel profile. This method has high processing efficiency and good consistency of the inner back arc of the blade. Therefore, It has been widely used in the processing of blades. However, when the blade is clamped on the rotary machine tool, it is positioned and pressed by the blade root, and the blade crown is positioned and tightened by the center hole. The steam passage part of the blade is in a suspended state, and certain processing deformation will occur when milling the profile in this state. , the thinner the steam channel profile, the greater the curvature, the more seri...
