Description

Technical Field

[0001] The present application relates to the technical field of precision casting production, and in particular, to a guide vane grinding support device. Background Art

[0002] The information provided in this section is for the purpose of generally presenting the background of the present application. To the extent described in this section, the work of the presently named inventors and aspects of the description that may not constitute prior art at the time of filing are neither explicitly nor implicitly admitted to be prior art to the present application.

[0003] None of the aspects described are admitted, either expressly or impliedly, to be prior art to the present application.

[0004] Guide vane castings produced by investment casting, such as aircraft engine power turbine guide vanes, gas turbine secondary guide vanes and other castings, are prone to defects such as under-cast blades and cold shuts after smelting and pouring. They need to be repaired after the defects are eliminated, and the weld scars on the blades need to be removed before they can pass the repair.

[0005] Since the shapes of the trailing edges of the blades vary in complexity, including straight lines and curves, and the operator can only rely on pure visual grinding, the process of removing the weld scars and restoring the original shape of the blades is extremely inefficient and has poor consistency. At the same time, it is also necessary to solve the problem of how the operator can conveniently support and limit the guide and adjust the position of the guide, so as to improve the efficiency of the guide blade grinding and reduce the labor intensity of the operator.

[0037] A guide blade grinding support device is used for supporting a guide 100 produced by investment casting and then grinding and trimming the blades of the guide 100. The guide blade grinding support device includes a profiling tool 200, a workbench 1, a support plate assembly, a support rod assembly, a limiter 6, a mounting member 8, an adjustment limiter 9, a push rod assembly and a clamping member 14:

[0038] The bottom end of the support rod assembly is hinged to the workbench 1, the top end of the support rod assembly is hinged to the mounting member 8, the support plate assembly is arranged on the workbench 1, the support plate assembly is used to support the limiter 6, the limiter 6 is used to pass through the support rod assembly and limit the support rod assembly to limit the support rod assembly from rotating around the hinge point on the workbench 1;

[0039] The push rod assembly is arranged in an annular array on the mounting member 8. The first end of the push rod assembly facing radially outward along the mounting member 8 is connected to the clamping member 14. The bottom end of the adjusting limit member 9 is threadedly connected to the mounting member 8. The adjusting limit member 9 is used to abut against the second end of the push rod assembly when being screwed into the preset connection screw hole on the mounting member 8, and push the push rod assembly and the clamping member 14 radially outward along the mounting member 8, thereby pushing the clamping member 14 to abut against the inner hole of the compression guide 100.

[0040] The contour tool 200 is used to fit into the blade gap of the guide 100 and serve as a reference for grinding.

[0041] Here, the meaning of "mounting member 8" refers to a structure that provides mounting support for the push rod assembly. In some embodiments, the mounting member 8 is a disc structure, and a connecting screw hole is provided at the center of the mounting member 8 to cooperate with the adjusting limit member 9. Of course, the mounting member 8 can also be made into a ring structure as a whole, and its inner hole is a connecting screw hole. Alternatively, the mounting member 8 can be made into a ring structure, and a middle connecting ring is provided in the middle, and the inner hole of the connecting ring is a connecting screw hole.

[0042] The guide blade grinding support device of the present application uses the profiling tool 200 to be inserted between the adjacent blades of the guide 100 as a reference for grinding, so as to avoid the blade trailing edge and other parts from being out of control during the grinding and trimming process, and solves the problem of dimensional over-tolerance and poor consistency during the grinding and trimming process of the blades of the guide 100. At the same time, the present application provides an installation and operation platform through the workbench 1, and realizes the rotation of the mounting member 8 through the hinge connection between the support rod assembly and the mounting member 8, and drives the mounting member 8 to rotate around the hinge point on the workbench 1 through the support rod assembly, and the push rod assembly on the mounting member 8 can drive the clamping member 14 to move radially along the mounting member 8, so as to compress and limit the inner hole of the guide 100, facilitate the clamping and disassembly of the guide 100, and after the stable clamping of the guide 100 is completed, it can be conveniently adjusted in multiple directions with the mounting member 8, so as to facilitate the workers to perform grinding operations on different parts, reduce the difficulty of the operator's work, and improve the grinding efficiency.

[0043] Preferably, please refer to Figure 5-9As shown, the profiling tooling 200 is a block structure with a cavity shape between adjacent blades of the profiling guide 100, and the profiling tooling 200 includes a first positioning edge 201, a second positioning edge 202, a third positioning edge 203 and a grinding support edge 204. The first positioning edge 201 is used to abut the trailing edge of one of the blades of the positioning guide 100 to angularly position the profiling tooling 200, the second positioning edge 202 is used to abut the back of the adjacent blade to axially position the profiling tooling 200, the third positioning edge 203 is used to abut the inner ring of the adjacent blade to radially position the profiling tooling, and the grinding support edge 204 is used to abut the trailing edge of the adjacent blade to serve as a supporting reference edge for grinding.

[0044] It can be understood that by inserting the profiling tool 200 between adjacent blades of the guide 100 and using the grinding support edge 204 as a reference edge for grinding, workers can perform grinding operations along the grinding support edge 204. The profiling tool 200 can be used as a grinding reference to unify the grinding references at different positions and improve the accuracy and consistency of grinding.

[0045] Taking the grinding and removal of the weld scar on the trailing edge of the blade as an example, first, the weld scar on the upper surface of the blade after the repair welding is flattened; the grinding support profiling tool 200 is positioned between the adjacent blades of the guide 100 through the first positioning edge 201, the second positioning edge 202, and the third positioning edge 203 in sequence, and the position of the profiling tool 200 is fixed; the shape of the trailing edge of the repaired blade can be drawn along the grinding support edge 204 with a pen, which is convenient for intuitive observation of the grinding benchmark; the excess weld scar is removed along the drawn line with a pen test air gun and a metal rotary file, and the shape of the trailing edge of the blade can be repaired, and the operation is very efficient.

[0046] Preferably, please refer to Figure 1 , 3 As shown, the support rod assembly includes a first support rod 4 and a second support rod 5, the bottom ends of the first support rod 4 and the second support rod 5 are hinged to the workbench 1, the top ends of the first support rod 4 and the second support rod 5 are hinged to the mounting member 8, the first support rod 4 and the second support rod 5 are cross-arranged along the radial direction of the mounting member 8, and the limiting member 6 is used to be horizontally placed above the intersection of the first support rod 4 and the second support rod 5 to limit the first support rod 4 and the second support rod 5 at the same time.

[0047] It can be understood that since the first support rod 4 and the second support rod 5 are cross-arranged, the limiting member 6 can be horizontally placed above the intersection of the first support rod 4 and the second support rod 5, and the two ends of the limiting member 6 are respectively connected and limited by the support plate assembly. The first support rod 4 and the second support rod 5 can be limited at the same time by the limiting member 6 to prevent the first support rod 4 and the second support rod 5 from rotating around the hinge point on the workbench 1, thereby realizing the limitation of the mounting member 8 and the guide 100, and facilitating the workers to perform grinding operations.

[0048] Preferably, please refer to Figure 3 As shown, a first stopper 15 is provided on the first support rod 4, and a second stopper 16 is provided on the second support rod 5. The first support rod 4, the first stopper 15, the second support rod 5 and the second stopper 16 form a limiting cavity along the radial projection of the mounting member 8. The limiting member 6 is used to pass through the limiting cavity to limit the first support rod 4 and the second support rod 5 at the same time, and the first stopper 15 and the second stopper 16 are used to limit the top of the limiting member 6.

[0049] It can be understood that by respectively arranging the first stopper 15 and the second stopper 16 on the first support rod 4 and the second support rod 5, and using the first stopper 15 and the second stopper 16 to limit the top of the limiter 6 after the limiter 6 is horizontally placed above the intersection of the first support rod 4 and the second support rod 5, it is beneficial to improve the limiting stability of the limiter 6, reduce the phenomenon of unstable limiting caused by the limiter 6 sliding upward, and ensure that the workers can perform the grinding operation smoothly.

[0050] Preferably, please refer to Figure 1 , 3 As shown, both ends of the limit member 6 are respectively passed through the support plate assembly, and the support plate assembly includes a first support plate 2 and a second support plate 3. The first support plate 2 and the second support plate 3 are arranged on opposite sides of the workbench 1. The first support plate 2 and the second support plate 3 are respectively provided with a first limit through hole and a second limit through hole. The first limit through hole and the second limit through hole are used for the limit member 6 to pass through so as to support the two ends of the limit member 6. A plurality of the first limit through holes and the second limit through holes are provided.

[0051] It can be understood that the two ends of the limiter 6 are respectively limited by the first support plate 2 and the second support plate 3, which can ensure the stable limiting of the first support plate 4 and the second support plate 5 by the limiter 6. In addition, a plurality of first limiter through holes on the first support plate 2 and a plurality of second limiter through holes on the second support plate 3 are provided, so that the first support plate 4 and the second support plate 5 can be limited by the limiter 6 when they rotate to different positions, thereby improving the accuracy of adjustment and control.

[0052] Optionally, a handle 7 is provided at one end of the limit member 6, and the handle 7 can facilitate the operator to insert the limit member 6 into the first support plate 2 and the second support plate 3. The handle 7 can also limit one end of the limit member 6 to prevent the limit member 6 from falling off the support plate assembly.

[0053] Preferably, please refer to Figure 2As shown, the push rod assembly includes a first push rod 11, a connecting tube 12, and a second push rod 13. The connecting tube 12 is arranged on the mounting member 8 along the radial direction of the mounting member 8. The first push rod 11 is slidably arranged on the first side of the connecting tube 12 toward the center of the mounting member 8, and the second push rod 13 is slidably arranged on the second side of the connecting tube 12. The first end of the second push rod 13 is connected to the locking member 14. A compression spring 17 is arranged in the connecting tube 12. The compression spring 17 is used to provide an elastic force to push the second push rod 13 toward the center of the mounting member 8; the first end of the first push rod 11 is used to abut against the adjusting limit member 9, and the adjusting limit member 9 is used to push the first end of the first push rod 11 to move radially outward along the mounting member 8, and push the second push rod 13 and the locking member 14 to move through the second end of the first push rod 11.

[0054] It is understandable that by adjusting the limiting member 9 to push the first push rod 11, the first push rod 11 drives the second push rod 13 and the clamping member 14 to move, so that the clamping member 14 can abut against the inner hole of the guide 100, and because the push rod assembly and the clamping member 14 are both arranged in a ring array, a stable clamping effect on the guide 100 can be achieved, ensuring that the worker can smoothly perform the grinding operation. When the guide 100 needs to be removed, it is only necessary to lift and adjust the limiting member 9 to retract the first push rod 11 and the second push rod 13, so that the clamping member 14 can release the clamping of the guide 100, and the disassembly is very simple and efficient, which is conducive to improving the overall work efficiency.

[0055] Optionally, the retaining member 14 is an arc-shaped plate structure, and a rubber pad is provided on the side wall where the retaining member 14 contacts the inner hole of the guide 100. The arc-shaped plate-shaped retaining member 14 can facilitate the guide 100 to be smoothly inserted onto the outside of the retaining member 14, and the rubber pad can provide buffering and protection.

[0056] Preferably, please refer to Figure 2 As shown, a limiting platform is arranged at the second end of the second push rod 13, a third stopper 18 is arranged in the connecting tube 12, and a compression spring 17 is pressed between the third stopper 18 and the limiting platform.

[0057] It can be understood that when the adjustment limit member 9 is lifted to release the squeezing push on the first push rod 11, the compression spring 17 can drive the second push rod 13 to move back toward the center of the mounting member 8, thereby driving the locking member 14 to release the limit on the inner hole of the guide 100, thereby completing the disassembly of the guide 100, which is beneficial to improving the overall disassembly efficiency.

[0058] Preferably, please refer to Figure 1 , 2 As shown, the adjustment limit member 9 is a conical structure that is wide at the top and narrow at the bottom. A threaded column is provided at the bottom end of the adjustment limit member 9, which is used to cooperate with the preset connecting screw hole on the mounting member 8. The first end of the first push rod 11 is an inclined structure that is inclined downward toward the center of the mounting member 8.

[0059] It can be understood that when the adjustment limit member 9 is screwed downward, the side wall of the adjustment limit member 9 can push the first push rod 11 to move outward along the axial direction of the connecting tube 12, that is, radially outward of the mounting member 8, thereby achieving the effect of pushing the second push rod 13 and the locking member 14, and the displacement of the locking member 14 can be accurately controlled by adjusting the limit member 9 so as to accurately complete the clamping operation.

[0060] Optionally, a handle 10 is provided on the top of the adjustment limiter 9, and the adjustment limiter 9 can be conveniently turned by the handle 10, thereby improving the convenience of operation.

[0061] Preferably, please refer to Figure 4 As shown, a pair of limit support plates 20 are arranged on the top of the first support rod 4, and a rotating shaft 21 is arranged between the limit support plates 20 on both sides. The two ends of the rotating shaft 21 are respectively connected to the preset bearings on the limit support plates 20 on both sides. A connecting rod 19 is arranged on the rotating shaft 21, and the other end of the connecting rod 19 is connected to the mounting member 8. The guide blade grinding support device also includes a locking assembly, which is used to lock the limit rotating shaft 21.

[0062] It can be understood that the mounting member 8 is connected to the rotating shaft 21 via the connecting rod 19, so that the mounting member 8 can rotate around the rotating shaft 21, which is convenient for adjusting the angle of the mounting member 8 and facilitating the workers' grinding operation.

[0063] It should be noted that the top end of the second support rod 5 can be hinged to the mounting member 8 through a rotating shaft or a hinge. It is only necessary to limit the position between the first support rod 4 and the mounting member 8, and the overall rotation of the mounting member 8 will be locked, which is beneficial to reduce the number of locking structures and reduce the overall manufacturing and maintenance costs.

[0064] Preferably, please refer to Figure 4 As shown, the locking assembly includes a limit clamp 23 and a locking nut 24. One end of the rotating shaft 21 extends out to form an extension portion 22 with the limit support plate 20 on one side. The limit clamp 23 is arranged on the side wall of the limit support plate 20 and is arranged in a circular array on the outside of the extension portion 22. The outer wall of the limit clamp 23 is a slope structure. The locking nut 24 is used to cooperate with the preset thread on the outer wall of each limit clamp 23 and compress each limit clamp 23 toward the center direction of the extension portion 22 when screwed in so that each limit clamp 23 presses the extension portion 22.

[0065] It can be understood that by tightening the locking nut 24, each limit clamp 23 can clamp the extension portion 22, thereby achieving the limitation of the rotating shaft 21 and fixing the rotation angle of the mounting member 8, making it convenient for workers to arbitrarily adjust the angle of the mounting member 8 and lock it, facilitating grinding operations and effectively improving the convenience and efficiency of workers' operations.

[0066] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
