Abstract
Description
Technical Field
[0001] This invention relates to the field of mechanical manufacturing technology, specifically to a tool, equipment, and method for closing the mounting seat hole. Background Technology
[0002] In the field of aero-engines, the precision and reliability of components are crucial, especially those located at critical connection points. For a specific type of aero-engine component, the material is the difficult-to-machine high-temperature alloy GH3536. GH3536 is known for its high strength, excellent corrosion resistance, and heat resistance, but its high hardness and toughness also make it prone to thermal deformation during machining, affecting the component's precision. This component has a wall thickness of 1.2mm to 1.4mm and poor overall rigidity. To ensure engine stability and other performance characteristics, the component features 12 evenly distributed support mounting seats on its smaller end. Each mounting seat also has a boss on its outer circumference. A ball joint and a ball head need to be installed in each mounting seat hole. The ball head rotatably connects to the ball joint seat. To prevent the ball joint from falling out, the bosses on the outer circumference of the support mounting seats need to be narrowed by 60° (i.e., a diameter reduction). Because the ball joint inside the support mounting base is a key part connecting the flame tube and the engine combustion chamber, the ball joint needs to rotate freely so that the locating pin can accurately enter the ball joint for connection when the combustion chamber components are assembled. Therefore, the finishing quality must be ensured after the ball joint seat is assembled into the support pin mounting base. Due to the difficulty in machining GH3536 high temperature alloy, as well as the poor overall rigidity and complex structure of the parts, this finishing process is particularly difficult.
[0003] Traditional finishing methods use impact finishing. Due to the part's structure, during processing, the front face of the support mounting base needs to be supported against a temporary pressure plate. Two people then hold the part down while one person manually strikes the punch with a hammer to finish the finishing process. This method requires visual inspection to ensure the punch and support mounting base hole are aligned. Due to individual differences, the finished finish may be uneven, with one side having more or less than the other. Because impact finishing is used, the finished area is prone to peeling due to varying individual force. Furthermore, the hammering can easily cause cracks and deformation, affecting the part's quality. Therefore, traditional finishing methods are not only time-consuming and labor-intensive, but also difficult to guarantee finishing quality, easily damaging the part, resulting in low overall production efficiency, low finished part qualification rate, and high cost.
[0004] To address the above issues, it is necessary to explore technologies and utilize existing production conditions to innovate processing methods to solve the problem of the finishing of the ball joint after assembling the support mounting base and the ball joint, so as to ensure the processing quality and efficiency of the parts, improve the processing quality of the parts, and enable the parts to meet the performance requirements of aero-engines. Summary of the Invention
[0005] To address the problems of easy damage to parts, low closing efficiency, and high cost in the existing technology of mounting seat hole closing, the present invention provides a tool, device, and method for closing mounting seat holes.
[0006] To achieve the above objectives, the present invention employs the following technical solution:
[0007] A tool for closing mounting hole, comprising a body and a tip;
[0008] The front end of the main body is provided with a front tongue; when closing, the front tongue cooperates with the U-shaped space located between the part and the support mounting base;
[0009] The tip is located inside the body and can move horizontally along the body. A constricting groove is provided at one end of the tip near the front tongue. The angle between the groove wall and the horizontal direction is equal to the angle between the side wall of the constricted boss and the horizontal direction. A pushing device is provided at the other end of the tip to push the tip toward the part and constrict the boss.
[0010] Optionally, the jacking device includes a clamping screw that passes through the rear end of the body and connects to the rear end of the tip.
[0011] Optionally, the clamping screw is connected to the center via a cylindrical pin.
[0012] Optionally, the end of the clamping screw furthest from the tip is detachably connected to a movable handle.
[0013] Optionally, a stop is provided at the end of the front tongue near the tip, and the bottom of the stop is provided with an arc-shaped surface, which fits against the outer wall of the support mounting base when the end is closed.
[0014] Optionally, the main body is provided with a keyway, which is parallel to the axis of the support mounting base and located directly above the axis of the support mounting base.
[0015] Optionally, a locating pin is provided radially on the top tip, and the free end of the locating pin is inserted into the keyway and can move freely within the keyway along the axial direction of the support mounting base.
[0016] Optionally, the body is also provided with a handle.
[0017] A parts processing device includes the aforementioned mounting seat hole closing tool.
[0018] A method for sealing the mounting hole using the aforementioned sealing tool includes:
[0019] The front tongue is placed against the inside of the U-shaped space between the part and the support mounting base, and fits against the inner wall of the U-shaped space;
[0020] Align the axis of the top point with the axis of the support mounting base, and make the end of the boss abut against the side wall of the constriction groove.
[0021] The jacking tip moves toward the part until the outer wall of the boss is completely flush with the side wall of the closing groove, thus completing the closing.
[0022] Compared with the prior art, the present invention has the following beneficial effects:
[0023] This invention discloses a tool for closing mounting holes, comprising a body and a tip. A front tongue is provided at the front end of the body. During closing, the front tongue engages with a U-shaped space between the part and the mounting base, ensuring the tool is stably positioned within this space. This guarantees the stability and accuracy of the closing process. Furthermore, the engagement of the front tongue with the U-shaped space effectively prevents deformation of the thin-walled part due to stress during closing. The tip is located inside the body, moving horizontally. A closing groove is provided at the tip near the front tongue. By ensuring the angle between the groove wall and the horizontal direction is equal to the angle between the side wall of the closed boss and the horizontal direction, the closing angle accuracy is guaranteed, effectively preventing inconsistencies due to individual operation. A pushing device is provided at the other end of the tip, allowing the tip to move towards the part for closing, preventing deformation and peeling of the closing area due to varying individual operating forces. This tool has a simple structure and is easy to operate. It can not only achieve precise sealing, but also save a lot of manpower and improve sealing efficiency and quality.
[0024] The jacking device includes a clamping screw, which passes through the rear end of the body and connects to the rear end of the tip. By using the clamping screw, during the closing process, the tip can be jacked up by rotating the screw to close the boss. This design is simple, has low manufacturing costs, and can provide sufficient jacking force.
[0025] The clamping screw is connected to the center point via a cylindrical pin, ensuring a secure connection between the clamping screw and the center point. This prevents loosening or detachment during the jacking process, improving the reliability and safety of the tool.
[0026] The end of the clamping screw furthest from the tip is detachably connected to a movable handle. The design of the movable handle allows the operator to easily rotate the clamping screw for jacking operations. Simultaneously, the detachable handle facilitates the carrying and storage of the tool.
[0027] A stop is provided at the end of the front tongue near the tip, and the bottom of the stop has an arc-shaped surface that fits against the outer wall of the support mounting base during the closing process. The stop further enhances the stable positioning of the tool during closing, preventing displacement. The arc-shaped surface at the bottom of the stop fits against the outer wall of the support mounting base, effectively positioning the tool while preventing damage to the outer wall of the support mounting base.
[0028] The main body has a keyway that is parallel to and directly above the axis of the support mounting base. This keyway design ensures that the tip remains parallel to the axis of the support mounting base during movement, thereby guaranteeing the accuracy and consistency of the finishing process.
[0029] A locating pin is radially arranged on the tip, and the free end of the locating pin is inserted into the keyway, allowing it to move freely within the keyway along the axis of the support mounting base. The locating pin's insertion into the keyway further restricts the movement direction of the tip, ensuring that the tip's pushing direction is always parallel to the axis of the support mounting base, thus further improving the stability and accuracy of the closing process.
[0030] The main body is also equipped with a handle, which makes it easier for the operator to hold and apply force to move the tool, thus improving the convenience and efficiency of operation.
[0031] The present invention also provides a parts processing equipment, including the above-mentioned mounting seat hole closing tool, which can realize automated or semi-automated closing operation, thereby improving production efficiency and processing quality.
[0032] This invention also provides a method for closing the aforementioned mounting hole closing tool. This method ensures the stability of the closing tool by placing the front tongue against the inner wall of the U-shaped space between the part and the supporting mounting base; then, aligning the axis of the tip with the axis of the supporting mounting base, and placing the end of the boss against the side wall of the closing groove, further ensuring the stability, accuracy, and consistency of the closing; finally, by pushing the tip towards the part until the outer wall of the boss is completely against the side wall of the closing groove, precise closing of the boss can be achieved, improving the machining quality and performance of the part. The method is simple, easy to operate, and highly efficient. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0045] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.
[0046] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0047] In the description of the embodiments of the present invention, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0048] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.
[0050] The present invention will be further described in detail below with reference to specific embodiments. These descriptions are for explanation purposes only and are not intended to limit the scope of the invention.
[0051] See Figure 1 and Figure 2For a specific type of aero-engine part, the material is the difficult-to-machine high-temperature alloy GH3536. GH3536 high-temperature alloy is known for its high strength, excellent corrosion resistance, and heat resistance, but its high hardness and toughness also make it prone to thermal deformation during processing, affecting the part's precision. The part's wall thickness reaches 1.2mm to 1.4mm, and its overall rigidity is poor. To ensure the engine's stability and other performance, the part has 12 evenly distributed support mounting seats 10 designed on its small end. Each support mounting seat 10 also has a boss 11 on its outer circle. A ball joint seat 12 and a ball head 13 need to be installed in the hole of each support mounting seat 10. The ball head 13 is rotatably connected to the inside of the ball joint seat 12. To prevent the ball joint seat 12 from falling out, the boss on the outer circle of the support mounting seat 10 needs to be narrowed by 60°, i.e., the diameter needs to be reduced. The structure after the reduction is shown in [reference needed]. Figure 2 Because the ball head 13 inside the support mounting base 10 is a key part connecting the flame tube and the engine combustion chamber, the ball head 13 needs to rotate freely so that the locating pin can accurately enter the ball head 13 for connection when the combustion chamber components are assembled. Therefore, the finishing quality must be ensured after the ball head seat 12 is assembled into the support mounting base 10. Due to the difficult machining of GH3536 high temperature alloy, as well as the poor overall rigidity and complex structure of the parts, this finishing process becomes particularly difficult.
[0052] Example 1
[0053] See Figures 3 to 5 This invention provides a tool for closing mounting holes, comprising a body 1, the front end of which is provided with a front tongue 4; during closing, the front tongue 4 engages with a U-shaped space located between the part and the support mounting base 10; a tip 2 is provided inside the body 1, which can move along the horizontal direction of the body 1; a closing groove 14 is provided at one end of the tip 2 near the front tongue 4, the angle between the groove wall of the closing groove 14 and the horizontal direction is equal to the angle between the side wall of the closed boss 11 and the horizontal direction; a pushing device is provided at the other end of the tip 2, used to push the tip 2 towards the part to close the boss 11.
[0054] During the closing process, simply place the front tongue 4 against the U-shaped space between the part and the support mounting base 10, ensuring it fits against the inner wall of the U-shaped space; align the axis of the tip 2 with the axis of the support mounting base 10, and place the end of the boss 11 against the side wall of the closing groove 14; push the tip 2 towards the part until the outer wall of the boss 11 is completely fitted against the side wall of the closing groove 14, completing the closing. This tool has a simple structure and is easy to operate. It not only achieves precise closing but also saves a significant amount of manpower, improving closing efficiency and quality.
[0055] Example 2
[0056] See Figures 3 to 5 This invention provides a tool for closing mounting holes, comprising a body 1 and a tip 2; the front end of the body 1 is provided with a front tongue 4; during closing, the front tongue 4 engages with a U-shaped space located between the part and the support mounting base 10; the tip 2 is disposed inside the body 1 and can move along the horizontal direction of the body 1; a closing groove 14 is provided at one end of the tip 2 near the front tongue 4, the groove wall of the closing groove 14 forming an angle of 30° with the horizontal direction; a clamping screw 5 is provided at the other end of the tip 2, the clamping screw 5 passing through the rear end of the body 1 and connecting to the rear end of the tip 2, optionally, the clamping screw 5 is connected to the tip 2 via a cylindrical pin 7, and a movable handle 9 is detachably connected to the end of the clamping screw 5 away from the tip 2. During closing, the movable handle 9 can be connected to the clamping screw 5, and by rotating the movable handle 9, the clamping screw 5 is pushed towards the part under the thread engagement with the body 1, thereby causing the tip 2 to move towards the part and closing the boss 11.
[0057] Example 3
[0058] See Figures 3 to 5 This invention provides a tool for closing mounting holes, comprising a body 1 and a tip 2; the front end of the body 1 is provided with a front tongue 4; during closing, the front tongue 4 engages with a U-shaped space located between the part and the support mounting base 10; the tip 2 is disposed inside the body 1 and can move along the horizontal direction of the body 1; a closing groove 14 is provided at one end of the tip 2 near the front tongue 4, the groove wall of the closing groove 14 forming an angle of 30° with the horizontal direction; a clamping screw 5 is provided at the other end of the tip 2, the clamping screw 5 passing through the rear end of the body 1 and connecting to the rear end of the tip 2, optionally, the clamping screw 5 is connected to the tip 2 via a cylindrical pin 7, and a movable handle 9 is detachably connected to the end of the clamping screw 5 away from the tip 2.
[0059] See Figure 6 The front tongue 4 is provided with a stop 6 near the tip 2. The bottom of the stop 6 is provided with an arc-shaped surface. When closing the part, the arc-shaped surface fits against the outer wall of the support mounting base 10, ensuring that when the closing tool is placed on the outer diameter of the support mounting base 10, the tip 2 is concentrically positioned with the hole of the support mounting base 10. This further improves the stable positioning of the tool during closing, prevents deviation during the closing process, and prevents the tool from damaging the outer wall of the support mounting base 10.
[0060] Example 4
[0061] See Figures 3 to 6This invention provides a tool for closing mounting holes, comprising a body 1 and a tip 2; the tip 2 is located inside the body 1 and moves horizontally; a handle 3 is provided on the body 1, optionally the handle 3 is installed at the rear end of the body 1; a front tongue 4 is provided at the front end of the body 1, which engages with a U-shaped space between the part and the support mounting base 10 during closing; a stop 6 is provided at the end of the front tongue 4 near the tip 2, the bottom of the stop 6 having an arc-shaped surface, which interacts with the support mounting base 10 during closing. The outer wall fits snugly. Optionally, the stop block 6 is connected to the body 1 by countersunk screws. The tip 2 can move horizontally along the body 1. The tip 2 is provided with a constricting groove 14 at one end near the front tongue 4. The groove wall of the constricting groove 14 forms an angle of 30° with the horizontal direction. The other end of the tip 2 is provided with a clamping screw 5. The clamping screw 5 passes through the rear end of the body 1 and connects to the rear end of the tip 2. Optionally, the clamping screw 5 is connected to the tip 2 by a cylindrical pin 7. The end of the clamping screw 5 away from the tip 2 is detachably connected to a movable handle 9.
[0062] The main body 1 is provided with a keyway 15, which is parallel to the axis of the support mounting base 10 and located directly above the axis of the support mounting base 10. The tip 2 is provided with a locating pin 8 in the radial direction. The free end of the locating pin 8 is inserted into the keyway 15 and can move freely in the keyway 15 along the axis of the support mounting base 10 to control the travel of the tip 2. Optionally, when the locating pin 8 moves to the end of the keyway 15 near the end of the part, it just meets the closing size requirement at the closing point.
[0063] See Figures 7 to 8 First, place the part with its large end facing down on the platform. Then, hold the handle 3 with one hand and pick up the finishing tool. With the other hand, rotate the movable handle 9 to adjust the distance between the tip 2 and the body 1 to be greater than the axial length of the support mounting base 10. Place the tool on the outer diameter of the support mounting base 10, ensuring that the stop block 6 fits against the outer diameter of the support mounting base 10. Place the front tongue 4 on the body 1 into the U-shaped space of the support mounting base 10 of the part, making it fit against the front face of the support mounting base 10. Make the end of the boss 11 abut against the side wall of the finishing groove 14 inside the tip 2. By rotating the movable handle 9, the tip 2 moves in the finishing direction. The finishing part of the boss 11 will be evenly squeezed and enter the 60° tapered hole on the tip 2, i.e., the finishing groove 14. When the positioning pin 8 on the tip 2 moves to the limit in the groove, the finishing size requirement is met. Reverse the movable handle 9, the tip 2 moves back, and the tool is removed. The finishing is complete, and the finishing of the next support mounting base 10 can be performed.
[0064] See Figure 9 and Figure 10To further illustrate the beneficial effects of this invention, a comparison is made between existing finishing methods and the finishing method of this invention. Traditional finishing methods use impact to finish the part. Due to the structure of the part, during processing, the front end of the support mounting base needs to be supported against a temporary pressure plate, then two people need to hold the part down while one person manually strikes the punch with a hammer to finish the finishing operation. It is evident that due to differences in individual force, the finished area will have numerous pits, resulting in poor finishing quality, and the hammering process poses safety hazards to both the part and the operator. When using the finishing tool provided by this invention, finishing can be easily achieved simply by rotating the movable handle 9, and the finished surface is smooth without any pits or damage, greatly improving finishing efficiency, finishing quality, and the safety of the finishing operation.
[0065] The present invention also provides a parts processing equipment, including the above-mentioned mounting seat hole closing tool, which can realize automated or semi-automated closing operation, thereby improving production efficiency and processing quality.
[0066] This invention provides a method for closing the mounting hole using the aforementioned tool, comprising:
[0067] S1: The front tongue 4 is placed against the inside of the U-shaped space between the part and the support mounting base 10 and fits against the inner wall of the U-shaped space;
[0068] S2: Align the axis of the tip 2 with the axis of the support mounting base 10, and make the end of the boss 11 abut against the side wall of the constriction groove 14.
[0069] S3: The push-in tip 2 moves towards the part until the outer wall of the boss 11 is completely fitted with the side wall of the closing groove 14, thus completing the closing.
[0070] This method ensures the stability of the closing tool by placing the front tongue 4 against the inner wall of the U-shaped space between the part and the support mounting base 10. Then, the axis of the tip 2 is aligned with the axis of the support mounting base 10, and the end of the boss 11 is placed against the side wall of the closing groove 14, further ensuring the stability, accuracy, and consistency of the closing. Finally, by pushing the tip 2 towards the part until the outer wall of the boss 11 is completely against the side wall of the closing groove, precise closing of the boss is achieved, improving the machining quality and performance of the part. The method is simple, easy to operate, and highly efficient.
[0071] In summary, this invention provides a tool, device, and method for closing mounting holes. By providing a front tongue at the front end of the main body, during closing, the front tongue engages with the U-shaped space between the part and the supporting mounting base. This allows the tool to be stably positioned within the U-shaped space, ensuring stability and accuracy in the closing process. Furthermore, the engagement of the front tongue with the U-shaped space effectively prevents deformation of the thin-walled part due to stress during closing. By ensuring that the angle between the wall of the closing groove and the horizontal direction is equal to the angle between the side wall of the closed boss and the horizontal direction, the closing angle accuracy is guaranteed, effectively preventing inconsistencies caused by individual operation. A jacking device at the other end of the tip allows the tip to move towards the part, closing the boss without deformation or peeling due to varying individual operating forces. This invention, through technological innovation, explores and summarizes a tool and operating method for quickly closing mounting holes, and uses a closing fixture to solve the quality problems of closing holes in this type of part. It has high technical content and reference value in terms of operability and practicality, and has also accumulated rich technical experience for the processing of similar parts in the future.
[0072] The above description is merely a preferred embodiment of the present invention and is not intended to limit the technical solution of the present invention in any way. Those skilled in the art should understand that, without departing from the spirit and principles of the present invention, the technical solution can be modified and replaced in several simple ways, and these modifications and replacements are all within the scope of protection covered by the claims.
