Embodiment 1

[0055] In order to solve the problem that the existing grinding method has different fixtures, grinding wheels and rollers used in different areas of processing the guide vane 47, resulting in complicated process switching process, low processing efficiency and low dimensional accuracy of the processed guide vane 47, Such as figure 2 , image 3 , Figure 4 and Figure 5 As shown, the present invention provides a multi-station continuous grinding device for guide vanes. The multi-station continuous grinding device for guide vanes includes: a four-axis linkage slow-feed grinder 1, a roller 2, a grinding wheel 3 and a fixture 4, and the roller 2 is installed on the roller shaft of the four-axis slow-feed grinding machine 1, the grinding wheel 3 is installed on the grinding wheel shaft of the four-axis slow-feed grinder 1, and the fixture 4 is installed on the rotary table 5 of the four-axis slow-feed grinder 1 ;

[0056] Such as Figure 4 As shown, the side of the roller 2 ...

Embodiment 2

[0079] The present invention provides a method for processing guide vanes using the multi-station continuous grinding device for guide vanes of the present invention, the method comprising:

[0080] Step 1, such as Figure 7 As shown, tighten the fifth compression screw 34 of the basin back positioning and clamping mechanism, so that the fifth compression screw 34 presses against the end of the blade body and basin of the basin back positioning and clamping mechanism towards the pressure plate 37, and the blade body and basin towards the pressure plate 37. The other end presses the second spring 38 of the positioning and clamping mechanism on the back of the basin to release the basin to the positioning and clamping mechanism;

[0081] When the fifth compression screw 34 is tightened, the fifth compression screw 34 will press the end of the blade body basin towards the pressure plate 37. Since the blade body basin phase pressure plate is installed on the bottom surface of the ...

Abstract

The invention discloses a multi-station continuous grinding device and method for a guide vane and belongs to the technical field of gas turbine vane machining. The multi-station continuous grinding device for the guide vane comprises a four-shaft linkage slow feeding grinding machine, a rolling wheel, a grinding wheel and a clamp; the rolling wheel is installed on a rolling wheel shaft of the four-shaft linkage slow feeding grinding machine; the grinding wheel is installed on a grinding wheel shaft of the four-shaft linkage slow feeding grinding machine; the clamp is installed on a rotating table of the four-shaft linkage slow feeding grinding machine; the side face of the rolling wheel comprises four grinding areas; the structure of the four grinding areas is the same as the structure of four machining areas of an installing plate of the guide vane; a structure ground by the side face of the rolling wheel and opposite to the concave and convex structure of the side face of the rolling wheel is formed on the side face of the grinding wheel; and the clamp comprises a bottom plate which is provided with an upper installing plate positioning and clamping mechanism, a lower installing plate positioning and clamping mechanism, a vane body tight pressing mechanism, a radial positioning and clamping mechanism and a pot back positioning and clamping mechanism. By means of the device and method, four to-be-machined stations of the guide vane can be subjected to continuous grinding.

Description

technical field [0001] The invention relates to the technical field of gas turbine blade processing, in particular to a multi-station continuous grinding device and method for guide blades. Background technique [0002] With the development of aviation machinery processing industry technology, the requirements for the accuracy of the mounting plate on the multi-connected guide vane are getting higher and higher. In the process of manufacturing aero-engine or gas turbine blades, the mounting plate and blade body of the guide Guaranteed casting without margin. Since the material of the guide vane is high-temperature casting alloy, which is a difficult-to-machine material, the processing performance is poor, resulting in low processing efficiency. The mounting plate of the guide vane is mainly machined to ensure accuracy. Feed grinding is used to machine the mounting plate of the guide vanes. [0003] The mounting plate of the guide vane mainly has four processing areas, such ...
