[0021] The honing device for a ceramic cylinder for an aero-engine according to an embodiment of the present invention has at least the following beneficial effects:

[0022] 1. The present invention provides a mounting member with a first cup body, which can deflect forward and backward and left and right. Therefore, the swing caused by clamping the ceramic cylinder can be corrected, so that the ceramic cylinder can be in the designed position, which facilitates uniform grinding of the ceramic cylinder, avoids uneven grinding, and improves the grinding accuracy.

[0023] Specifically, although the first cup body can swing back and forth and left and right, the intersection of the center line of the first cup body's back and forth swing and the center line of the left and right swing will not change. Therefore, when the grinding tool enters the inner side of the ceramic cylinder for grinding, the grinding tool abuts the inner surface of the ceramic cylinder, so that the inner surface of the ceramic cylinder remains upright with the intersection as the center. Furthermore, when the grinding tool moves in a circular motion along the inner surface of the ceramic cylinder and squeezes the ceramic cylinder, the grinding can be performed evenly along the circumference of the inner surface of the ceramic cylinder, thereby improving the grinding accuracy.

[0024] 3. The present invention provides a first cup body, which facilitates the placement of a ceramic cylinder inside the first cup body, so that the center of the first cup body tends to coincide with the center of the ceramic cylinder, thereby improving the stability of the fixture and reducing vibration during the grinding process.

[0025] 4. The present invention provides the first cup body, which facilitates the external connection of the first cup body with the transmission structure, thereby facilitating the front-back and left-right swinging.

[0026] 5. The present invention provides a positioning piece with a second cup body, so that the inner surface and top edge of the second cup body can be conveniently used to position the ceramic cylinder, reducing the difficulty of positioning. At the same time, ceramic cylinders of different specifications can be switched by replacing the second cup body, which facilitates product switching.

[0027] 6. The present invention provides a fixing assembly with a crossbeam and a pressing piece, thereby fixing the crossbeam on the first cup body. Then, the pressing piece is rotated so that the pressing piece abuts against the ceramic cylinder. Therefore, the pressing piece and the second cup body fix the ceramic cylinder to prevent the ceramic cylinder from moving up and down. Therefore, the grinding tool can grind the upper and lower positions of the inner surface of the ceramic cylinder.

[0028] 7. The present invention provides a pressing member with a guide channel and a guide opening. Therefore, when the grinding tool moves toward the ceramic cylinder, the grinding tool first contacts the pressing member. Specifically, the grinding tool first contacts the guide opening and then contacts the guide channel, so that the ceramic cylinder returns to the center, facilitating the grinding tool's entry into the interior of the ceramic cylinder and avoiding contact with the top surface of the ceramic cylinder, thereby preventing damage to the ceramic cylinder.

[0037] A honing device for a ceramic cylinder for an aircraft engine according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0038] The present invention aims to provide an embodiment of a honing device for a ceramic cylinder used in an aircraft engine, with the purpose of overcoming the influence of clamping deviation and improving manufacturing accuracy.

[0039] In this embodiment, the grinding device includes a frame, on which a grinding tool is provided. The grinding tool can rotate, rise and fall, and move horizontally. Therefore, when the grinding tool descends, the grinding tool enters the interior of the ceramic cylinder. Then, the grinding tool moves horizontally in a circular motion along the inner surface of the ceramic cylinder. At the same time, the grinding tool rotates to grind the inner surface of the ceramic cylinder.

[0040] In this embodiment, the frame is provided with a horizontally movable workbench, which can be moved in translation or in rotation, so that the fixture can be switched between the grinding station and the clamping station.

[0041] In some specific embodiments of the present invention, the workbench can be a turntable that can rotate at an indexing rate, so that multiple fixtures can be installed on the turntable, so that the ceramic cylinder on one fixture is ground and the other fixture is used for loading.

[0042] In some specific embodiments of the present invention, the turntable can be provided with at least three fixtures, one for loading, one for unloading, and one for grinding. Therefore, compared with the arrangement of four or five fixtures, space can be saved and manufacturing costs can be reduced. At the same time, compared with the arrangement of one or two fixtures, continuous unloading and loading of the same fixture can be avoided, and the loading and unloading time can be avoided from being too long to affect the rotation speed of the turntable.

[0043] Reference Figure 1 and Figure 2 The present invention also aims to provide an embodiment of a fixture for a honing device of a ceramic cylinder for an aircraft engine, wherein the fixture is used to install the ceramic cylinder.

[0044] In this embodiment, the fixture includes a base 12, which can be mounted on a turntable to facilitate sequential grinding.

[0045] In some specific embodiments of the present invention, the base 12 and the turntable can be positioned by matching the shaft hole, so that the positioning is precise and the assembly error is reduced.

[0046] In some specific embodiments of the present invention, the bottom of the base 13 may have a cylinder or a ring to facilitate the positioning of the shaft hole and facilitate manufacturing.

[0047] In some specific embodiments of the present invention, the base 12 may have two opposing columns, with a mounting ring 13 disposed between the two columns. The radial outer surface of the mounting ring 13 is rotatably connected to the two columns, so that the mounting ring 13 can be flipped between the two columns.

[0048] In some specific embodiments of the present invention, a limiting structure may be provided to geometrically interfere with the rotation range of the mounting ring 13 .

[0049] In this embodiment, the fixture further has a mounting member, which includes a first cup body 1 . The top of the first cup body 1 is open, the first cup body 1 is located in the mounting ring 13 , and the outer side of the first cup body 1 is rotatably connected to the inner side of the mounting ring 13 .

[0050] In some specific embodiments of the present invention, the rotation direction of the mounting ring 13 relative to the base 12 can be inconsistent with the rotation direction of the first cup body 1 relative to the mounting ring 13, thereby causing the first cup body 1 to swing forward and backward and left and right.

[0051] In some specific embodiments of the present invention, the rotation direction of the mounting ring 13 relative to the base 12 can be perpendicular to the rotation direction of the first cup body 1 relative to the mounting ring 13, thereby expanding the swing range of the first cup body 1 and facilitating manufacturing and assembly.

[0052] In some specific embodiments of the present invention, the top of the first cup body 1 can be rotatably connected to the mounting ring 13, so that the first cup body 1 can automatically stand upright by utilizing gravity, thereby simplifying or reducing the structure that restricts rotation.

[0053] In some specific embodiments of the present invention, the first cup body 1 may have an outer convex edge, and a ring is installed at the bottom of the outer convex edge. The ring is rotatably connected to the mounting ring 13 through a pin and a hole, thereby facilitating manufacturing and assembly.

[0054] In this embodiment, the fixture also includes a positioning member, which includes a second cup body 2. The top of the second cup body 2 is open and the second cup body 2 is installed in the first cup body 1. The top edge and inner surface of the second cup body 2 are used to position the ceramic cylinder.

[0055] In this embodiment, the clamp further includes a fixing assembly, including a beam 3 spanning the top of the first cup body 1 and a pressing member 4 liftably disposed on the beam 3 .

[0056] At least one end of the crossbeam 3 is detachably connected to the first cup body 1 , so that the crossbeam 3 can be kept away from the top of the first cup body 1 , making it convenient to take and place the ceramic cylinder.

[0057] The bottom of the pressing member 4 is used to abut the ceramic cylinder. A guide channel 16 is formed inside the pressing member 4 to accommodate the grinding tool into the ceramic cylinder. A guide port 15 connected to the guide channel 16 is provided on the top of the pressing member 4.

[0058] In summary, firstly, in this embodiment, a mounting part is provided so that the mounting part has a first cup body 1, and the first cup body 1 can swing back and forth and left and right. Therefore, the swing caused by clamping the ceramic cylinder can be corrected, so that the ceramic cylinder can be in the designed position, which is convenient for uniform grinding of the ceramic cylinder, avoids uneven grinding, and improves the grinding accuracy.

[0059] Specifically, although the first cup body 1 can swing back and forth and left and right, the intersection of the center line of the first cup body 1 swinging back and forth and the center line of the left and right swinging will not change. Therefore, when the grinding tool enters the inner side of the ceramic cylinder for grinding, the grinding tool abuts the inner surface of the ceramic cylinder, so that the inner surface of the ceramic cylinder remains upright with the intersection as the center. Furthermore, when the grinding tool moves in a circular motion along the inner surface of the ceramic cylinder and squeezes the ceramic cylinder, it can be evenly ground along the circumference of the inner surface of the ceramic cylinder, thereby improving the grinding accuracy.

[0060] Secondly, by setting the first cup body 1, this embodiment also facilitates the placement of a ceramic cylinder inside the first cup body 1, so that the center of the first cup body 1 tends to coincide with the center of the ceramic cylinder, thereby improving the stability of the fixture and reducing vibration during the grinding process.

[0061] Furthermore, by providing the first cup body 1, this embodiment facilitates the external connection of the first cup body 1 with a transmission structure, thereby facilitating front-to-back and left-to-right swinging.

[0062] In addition, this embodiment provides a positioning piece so that the positioning piece has a second cup body 2. Therefore, the inner surface and top edge of the second cup body 2 can be conveniently used to position the ceramic cylinder, reducing the difficulty of positioning. At the same time, by replacing the second cup body 2, ceramic cylinders of different specifications can be switched, which facilitates product switching.

[0063] At the same time, this embodiment sets a fixing component so that the fixing component has a crossbeam 3 and a pressing piece 4, so that the crossbeam 3 is fixed on the first cup body 1, and then the pressing piece 4 is rotated so that the pressing piece 4 abuts against the ceramic cylinder. Therefore, the pressing piece 4 and the second cup body 2 fix the ceramic cylinder to prevent the ceramic cylinder from moving up and down. Therefore, the grinding tool can grind the upper and lower positions of the inner surface of the ceramic cylinder.

[0064] In addition, in this embodiment, the pressing member 4 is provided with a guide channel 16 and a guide opening 15. Therefore, when the grinding tool moves toward the ceramic cylinder, the grinding tool first contacts the pressing member 4. Specifically, the grinding tool first contacts the guide opening 15 and then contacts the guide channel 16, so that the ceramic cylinder returns to the center, making it easier for the grinding tool to enter the interior of the ceramic cylinder and avoid contacting the top surface of the ceramic cylinder to prevent damage to the ceramic cylinder.

[0065] In some specific embodiments of the present invention, openings can be provided at the bottoms of the first cup body 1 and the second cup body 2 to facilitate the discharge of coolant and debris generated by grinding.

[0066] In some specific embodiments of the present invention, the mouth can be preferentially arranged at the connection between the bottom wall and the side wall of the cup body, thereby making it convenient to check the conditions of the bottom wall and the side wall and to clean from the side downward.

[0067] In some specific embodiments of the present invention, the clamping member 4 can include a spinning sleeve 5 spirally connected to the crossbeam 3, and a clamping ring 6 rotatably connected to the spinning sleeve 5. The top of the spinning sleeve 5 forms a guide opening 15, and the inner sides of the spinning sleeve 5 and the clamping ring 6 cooperate to form a guide channel 16. The clamping ring 6 is used to abut the ceramic cylinder.

[0068] It is easy to understand that in this embodiment, the clamping member 4 includes a spinning sleeve 5 and a clamping ring 6. Therefore, the spinning sleeve 5 can be rotated to achieve lifting and lowering, and the clamping ring 6 is rotatably connected to the spinning sleeve 5. The clamping ring 6 contacts the ceramic cylinder without rotating, thereby avoiding damage to the ceramic cylinder due to friction.

[0069] In some specific embodiments of the present invention, a guide column 7 and a guide hole for sliding connection may be provided between the crossbeam 3 and the clamping ring 6 .

[0070] It is easy to understand that, by providing the guide pillars 7 and the guide holes, the clamping ring 6 can be lifted and lowered smoothly, pressed evenly on the ceramic cylinder, and prevented from being biased.

[0071] In some specific embodiments of the present invention, a pin hole structure may be provided between the clamping ring 6 and the ceramic cylinder to further prevent the clamping ring 6 and the ceramic cylinder from rotating relative to each other.

[0072] In some specific embodiments of the present invention, a bearing may be provided between the clamping ring 6 and the rotating sleeve, which not only meets the rotation requirement but also facilitates the rotating sleeve to drive the clamping ring 6 to move up and down.

[0073] In some specific embodiments of the present invention, a handle 17 may be provided on the outer side of the spinning sleeve 5 , and the handle 17 is located on the top of the crossbeam 3 .

[0074] It is easy to understand that in this embodiment, by holding the handle 17, the spinning sleeve 5 can be conveniently rotated to conveniently press and fix the ceramic cylinder.

[0075] In some specific embodiments of the present invention, the crossbeam 3 can be completely removed during use, but it is easy to fall off.

[0076] In some specific embodiments of the present invention, one end of the beam 3 can be rotatably connected to the first cup body 1, and the beam 3 can swing horizontally. The first cup body 1 is provided with a limiting column 9, and the other end of the beam 3 is provided with a limiting notch 8 for accommodating the limiting column 9. The top of the limiting column 9 is provided with a limiting protrusion 10 for limiting the up and down movement of the beam 3.

[0077] It is easy to understand that in this embodiment, one end of the beam 3 is connected to the first cup body 1 by rotation. Therefore, the beam 3 can be moved away from the top of the first cup body 1 by horizontal rotation, which makes it convenient to take and place the ceramic cylinder without increasing labor intensity.

[0078] At the same time, the limiting column 9 and the limiting notch 8 can cooperate with the limiting beam 3 to facilitate the clamping member 4 to locate the ceramic cylinder, and the limiting protrusion 10 can prevent the beam 3 from rising, making it convenient for the clamping member 4 and the second cup body 2 to cooperate and fix the ceramic cylinder.

[0079] In some specific embodiments of the present invention, the crossbeam 3 may be provided with a reversible limiting arm 11 , and the limiting arm 11 and the limiting notch 8 cooperate to accommodate the limiting column 9 .

[0080] It is easy to understand that, by providing the limiting arm 11 in this embodiment, the limiting column 9 and the limiting notch 8 can be prevented from being separated from each other, thereby ensuring that the ceramic cylinder is fixed continuously and effectively.

[0081] In some specific embodiments of the present invention, the second cup body 2 can be detachably fixed to the bottom wall of the first cup body 1 .

[0082] It is easy to understand that in this embodiment, by fixing the second cup body 2 to the bottom wall of the first cup body 1, installation can be simplified and assembly can be facilitated.

[0083] In some specific embodiments of the present invention, the bottom wall of the first cup body 1 and the bottom of the second cup body 2 can be connected by screws extending up and down. The installation method is simple and effective, and replacement is convenient.

[0084] At the same time, this embodiment also allows the outer dimensions of the second cup body 2 to be close to the inner dimensions of the first cup body 1, thereby allowing the second cup body 2 to have multiple specifications, which is beneficial for universal use.

[0085] In some specific embodiments of the present invention, a positioning groove 14 for accommodating the bottom of the second cup body 2 may be provided at the bottom of the first cup body 1 .

[0086] It is easy to understand that in this embodiment, the bottom of the second cup body 2 is positioned by the positioning groove 14, so that a circular hole with a larger diameter can be used to position the second cup body 2, and the positioning accuracy is high.
