Description

Technical Field

[0001] This invention belongs to the field of aero-engine assembly, specifically relating to a perforated plate for preventing misalignment of holes in a sector-shaped part and its usage method. Background Technology

[0002] The sector-shaped segment is a set of sealing components embedded in the main combustion unit of a certain type of aero-engine. Its main functions include isolating high-temperature combustion gases and supporting the overall structure of the casing. This sector-shaped segment is machined from a ring forging and then cut, resulting in 21 pieces after the entire ring is cut. The front face of the part has a total of 12 holes, 5 of which are fitted with pins. After assembly, 3 punch points are made at the hole openings, evenly distributed along the circumference. These punch points tighten the hole openings and prevent the pins from falling off or wearing due to vibration, thus preventing pin loosening. Currently, due to the lack of clamping tools for positioning the punch points, operators generally use the punch to visually select the punch point positions. Although the punch points meet the acceptance standards, the consistency of the circumferential distribution is poor, and it requires a high level of operator skill. Careless operation can cause chamfering, damage, and deformation of the hole openings, or the punch slipping and scratching the part surface, potentially rendering the part unusable.

[0003] To address the above issues, it is necessary to explore new technologies and utilize existing production conditions to innovate processing methods to solve the problem of punching holes in parts, thereby ensuring efficient and aesthetically pleasing delivery of parts. Summary of the Invention

[0004] The purpose of this invention is to provide a punch plate for preventing mispositioning of punch points in the openings of sector-shaped parts and a method for using it, so as to solve the technical problems of poor consistency in the circumferential position distribution of punch points and high operational difficulty in the prior art.

[0005] To achieve the above objectives, the present invention employs the following technical solution: In a first aspect, this application discloses a perforated plate for preventing misalignment of the punching point of a sector segment part, comprising a sector segment plate adapted to the sector segment part, the sector segment plate being mounted on the sector segment part, a bushing being detachably provided on the sector segment plate, a spring being provided inside the bushing, and a punch for punching the point being provided at the spring.

[0006] Preferably, the sector-shaped perforated plate has through holes, and the sector-shaped perforated plate is fixed to the sector-shaped segment part by cylindrical pins.

[0007] Preferably, the sector-shaped perforated plate is provided with a positioning step hole adapted to the sector-shaped segment part, and the position of the positioning step hole corresponds to the position of the punching point of the sector-shaped segment part.

[0008] Preferably, when the bushing is in operation, it is installed at the positioning step hole on the sector plate, and the bushing has a step hole inside for assembling the spring and punch.

[0009] Preferably, the spring is fitted onto the stepped surface inside the bushing, and the punch passes through the spring and bushing for punching.

[0010] Preferably, the punch includes a first column and a second column, the diameter of the first column is smaller than that of the second column, the first column passes through the bushing and the spring for punching, and the end face of the second column contacts the spring.

[0011] Secondly, this application discloses a method for using the anti-mispositioning perforation plate for the perforation of a sector segment part as described in any one of the above claims, including: Install the sector-shaped perforated plate onto the sector-shaped segment part; The spring and punch are sequentially installed into the bushing; The punch with the bushing assembled is passed through the sector-shaped perforated plate to make a punching mark.

[0012] Preferably, the sector-shaped perforated plate has a through hole, and the sector-shaped perforated plate is fixed to the sector-shaped segment part by a cylindrical pin; including: Cylindrical pins are used to install the sector-shaped perforated plate onto the sector-shaped segment parts; The spring and punch are sequentially installed into the bushing; The punch with the bushing assembled is passed through the sector-shaped perforated plate to make a punching mark.

[0013] Preferably, the sector-shaped perforated plate is provided with a positioning step hole adapted to the sector-shaped segment part, the position of the positioning step hole corresponding to the punching point position of the sector-shaped segment part, including: Install the sector-shaped perforated plate onto the sector-shaped segment part; The spring and punch are sequentially installed into the bushing; The punches with the bushings assembled are passed through the positioning step holes of the sector plate in sequence to make punching points.

[0014] Preferably, when the punch with the bushing installed passes through the fan-shaped perforated plate to make a punching motion, the spring is compressed and generates a rebound force on the punch.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention, through technological innovation, designs a perforated plate for preventing misalignment of punching points on sector-shaped parts. The angular positional relationship between the Q5 hole (φ1.6-0.018-0.0322), the Q3 hole (φ3.14+0.1207), and the Q4 hole (φ2.41-0.018-0.0323) on the part's end face is used to determine the hole positions of the sector-shaped perforated plate. Simultaneously, the cylindrical pins on both sides of the sector-shaped perforated plate, in conjunction with the holes on the left and right sides of the part, constrain the position of the perforated plate, thus ultimately determining the punching point position. Furthermore, the addition of bushings and spring elements to the sector-shaped perforated plate makes the punching process more stable. This effectively solves the problem of poor circumferential position consistency when operators visually select punching points, and it does not require a high level of operator skill. It prevents problems such as chamfering, damage, and deformation of the hole opening caused by careless operation, and also prevents the quality risks of the punch slipping and scratching the part surface.

[0016] It has high technical content and reference value, and has also accumulated rich technical experience for the processing of similar parts in the future. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings: See Figure 3This application discloses a perforated plate for preventing misalignment of punching points on a sector-shaped part. The perforated plate 1 is adapted to the sector-shaped part and mounted on it. A bushing 3 is detachably mounted on the perforated plate 1, and a spring 5 is housed within the bushing 3. A punch 4 for punching points is positioned at the spring 5. The hole position of the perforated plate 1 is determined by the angular positional relationship of the part's end face, ensuring the perforated plate 1 fits the sector-shaped part. This facilitates rapid and accurate machining, reducing machining difficulty. The bushing and spring configuration further stabilizes the punching process. This effectively solves the problem of poor circumferential position consistency when operators visually select punching points, and it requires less skill from the operator. It prevents problems such as chamfering, damage, and deformation of the hole opening caused by careless operation, while also preventing quality risks such as the punch slipping and scratching the part's surface.

[0027] In some embodiments, a perforated plate for preventing misalignment of the punching point on a sector segment part includes a sector-shaped perforated plate 1, which is adapted to the sector segment part and mounted on it. A bushing 3 is detachably mounted on the sector-shaped perforated plate 1, and a spring 5 is disposed within the bushing 3. A punch 4 for punching is located at the spring 5. The sector-shaped perforated plate 1 has a through hole and is fixed to the sector segment part by a cylindrical pin 2. This application utilizes the structural features of the part itself to achieve precise positioning and improves the stability of the punching process through ingenious component design. Specifically, by determining the angular position of the end face of the part, we can accurately determine the position of the hole in the sector-shaped perforated plate on the part. This is similar to precisely assembling a jigsaw puzzle based on the shape and angular relationship of each piece. Simultaneously, the cylindrical pins on the left and right sides of the sector-shaped perforated plate cooperate with the holes on the left and right sides of the part, like a key inserted into a lock, further constraining the position of the perforated plate and thus accurately determining the punching point position. In addition, the bushings and spring elements added to the sector plate also play a crucial role. The springs can apply a stable force to the punch, keeping it in a relatively stable state during the punching process, reducing wobbling and deviation, just like installing a stabilizer for the punch.

[0028] In some embodiments, a suitable sector-shaped perforated plate is manufactured according to the specific dimensions and structure of the part to be processed. The size, shape, and position of the holes on the sector-shaped perforated plate 1 are perfectly matched to the part. After the sector-shaped perforated plate 1 is manufactured, it is installed on the sector-shaped part, ensuring that the cylindrical pins on the left and right sides of the sector-shaped perforated plate are accurately inserted into the corresponding holes on the left and right sides of the part, thereby fixing the position of the perforated plate. Next, a bushing is detachably installed on the sector-shaped perforated plate. This detachable design is ingenious, facilitating operation when changing the processing position later. Then, a spring is installed inside the bushing, and the punch used for punching is placed at the spring. During punching, the bushing increases the stability of the punching process, and the spring aims to generate a certain rebound when the punch contacts the surface of the part, preventing the operator from applying excessive force and causing deformation of the part.

[0029] In some embodiments, a perforated plate for preventing misalignment during punching of a sector-shaped part's orifice includes: a sector-shaped perforated plate 1, a cylindrical pin 2, a bushing 3, a punch 4, and a spring 5. The perforated plate uses the sector-shaped perforated plate 1 as the main component. The spring 5 is installed at the inner stepped surface of the bushing 3, and then the punch is installed into the entire bushing 3. Simultaneously, the bushing increases the stability of the punching process, and the spring's purpose is to generate a certain rebound when the punch contacts the part's surface, preventing the operator from applying excessive force and causing deformation of the part. This application, in conjunction with existing dedicated punching fixtures, enables rapid and accurate processing, reduces processing difficulty, improves product quality, increases work efficiency, and reduces labor costs.

[0030] In some embodiments, see Figure 4 The sector-shaped perforated plate 1 has through holes and is fixed to the sector-shaped segment part by cylindrical pins 2. This facilitates disassembly while ensuring that all holes on the perforated plate are aligned with the positions of the punching points.

[0031] In some embodiments, the sector-shaped perforated plate 1 is provided with positioning stepped holes adapted to the sector-shaped segment parts. The position of the positioning stepped holes corresponds to the punching point position of the sector-shaped segment parts. The hole positions of the sector-shaped perforated plate are determined by the angular positional relationship of each hole on the end face of the part. At the same time, the cylindrical pins on the left and right sides of the sector-shaped perforated plate cooperate with the holes on the left and right sides of the part to constrain the position of the perforated plate, thereby finally determining the punching point position. There are a total of Q5 holes with a diameter of φ1.6-0.018-0.0322, Q3 holes with a diameter of φ3.14+0.1207, and Q4 holes with a diameter of φ2.41-0.018-0.0323 on the front end face of the sector-shaped segment parts. The Q5 holes and Q4 holes are fitted with pins. After assembly, three punching points are made at the hole openings, evenly distributed along the circumference.

[0032] In some embodiments, see Figure 5 When the bushing 3 is in operation, it is installed at the positioning step hole on the sector plate 1, and the bushing 3 has a step hole inside for assembling the spring 5 and the punch 4. The bushing 3 increases the stability of the punching process.

[0033] In some embodiments, the spring 5 is fitted inside the bushing 3 at the stepped surface, and the punch 4 passes through the spring 5 and the bushing 3 for punching. The purpose of the spring 5 is to generate a certain amount of rebound when the punch 4 contacts the surface of the part, preventing the operator from applying excessive force and causing deformation of the part.

[0034] In some embodiments, see Figure 6 The punch 4 includes a first column 401 and a second column 402. The diameter of the first column 401 is smaller than that of the second column 402. The first column 401 passes through the bushing 3 and the spring 5 for punching. The end face of the second column 402 is in contact with the spring 5.

[0035] See Figure 1 , Figure 2 The front face of the sector-shaped segment part has a total of Q5 holes with a diameter of φ1.6-0.018-0.0322, Q3 holes with a diameter of φ3.14+0.1207, and Q4 holes with a diameter of φ2.41-0.018-0.0323. Pins are installed in the Q5 and Q4 holes. After assembly, three punching points are made at the hole openings, evenly distributed along the circumference. The invention's designed sector-shaped perforated plate has two cylindrical pins at its left and right ends. When assembling the sector-shaped perforated plate, the position of the fixed sector-shaped perforated plate can be determined by inserting the cylindrical pins into the two Q3 holes with a diameter of φ3.14+0.120 on the left and right sides of the sector segment, while ensuring that all holes on the perforated plate and the positions of the punching points are consistent. Simultaneously, the bushing increases the stability of the punching process, and the spring aims to generate a certain rebound when the punch contacts the part surface, preventing deformation of the part due to excessive force applied by the operator.

[0036] This application also discloses a method for using a punched anti-mispositioning hole plate for a sector-shaped part, including: Install the sector-shaped perforated plate 1 onto the sector-shaped segment part; Spring 5 and punch 4 are sequentially installed into bushing 3; The punch 4, with the bushing 3 assembled, passes through the sector-shaped perforated plate 1 to punch. The bushing increases the stability of the punching process, and the spring is designed to provide a certain amount of rebound when the punch contacts the surface of the part, preventing the operator from applying too much force and causing deformation of the part.

[0037] In some embodiments, a method of using a punched anti-mispositioning hole plate for a sector-shaped part includes: The sector-shaped perforated plate 1 is installed on the sector-shaped segment part using cylindrical pins 2; Spring 5 and punch 4 are sequentially installed into bushing 3; The punch 4, with the bushing 3 assembled, is passed through the sector-shaped perforated plate 1 to make a punching mark.

[0038] In some embodiments, a method of using a perforated plate for preventing mispositioning of holes in a sector segment part includes: installing the sector perforated plate 1 on the sector segment part; Spring 5 and punch 4 are sequentially installed into bushing 3; The punch 4, with the bushing 3 assembled, is passed through the positioning step hole of the sector plate 1 in sequence to punch the points.

[0039] In some embodiments, when the punch 4 with the bushing 3 installed passes through the fan-shaped perforated plate 1 to punch, the spring 5 is compressed, generating a restoring force on the punch 4. The combination of the bushing and the spring is also crucial. The spring can provide continuous and stable support to the punch, buffer the force on the punch during punching, reduce the wobbling or deviation of the punch, and make the punching process smoother.

[0040] In some embodiments, the method for controlling the punching position of the orifice on the sector-shaped perforated plate 1 is to determine the hole position of the sector-shaped perforated plate by the angular positional relationship of each hole on the end face of the part, and at the same time, the cylindrical pins on the left and right sides of the sector-shaped perforated plate cooperate with the holes on the left and right sides of the part to constrain the position of the perforated plate, thereby finally determining the punching position. The steps of using a perforated plate for preventing misalignment of the punching position on a sector-shaped part are as follows: Step 1: Install the sector segment part into the fixture, and at the same time use the cylindrical pins 2 on the left and right sides of the sector segment plate 1 to insert into the Q3 holes on the left and right sides of the sector segment part. Step 2: Install spring 5 into the upper end of the inner stepped surface of bushing 3; Step 3: Insert the punch 4 into the bushing 3, with the punch head facing upwards and resting on the spring 5; Step 4: Align the punch with bushing 3 installed with the positioning hole of the sector plate 1, and process one of the three punch points, Q5 hole and Q4 hole, in sequence, for a total of 5 holes.

[0041] Step 5: Using the other two types of sector-shaped perforated plates, continue processing two of the three evenly distributed punch points for holes Q5 and Q4, following steps 1-4. This method offers significant technical advantages, effectively solving several problems inherent in traditional punching operations. First, it completely eliminates the problem of poor circumferential position consistency when operators visually select punching points. Previously, visual operation could result in deviations in punching position each time; now, through precise positioning, the punching position remains consistent, greatly improving punching accuracy. Second, it significantly reduces the skill requirements for operators. Following the fixed steps disclosed in this application, even less skilled operators can successfully complete the punching work, reducing training costs and improving overall production efficiency. Furthermore, it effectively avoids problems such as squeezed, damaged, or deformed chamfered holes due to improper operation, while also preventing quality hazards caused by punch slippage and scratches on the part surface. It's like adding a "safety net" to the punching process, providing excellent protection for the parts during processing, significantly improving overall product quality, and reducing rework and waste caused by damaged parts.

[0042] In summary, this application belongs to the field of aero-engine assembly, specifically relating to a perforated plate for preventing misalignment of the punching point on a sector-shaped part and its usage method. It includes a sector-shaped perforated plate adapted to the sector-shaped part and mounted on it. A bushing is detachably mounted on the perforated plate, containing a spring, and a punch for punching is located at the spring. The position of the hole in the sector-shaped perforated plate is determined by the angular positional relationship of the part's end face, ensuring the plate fits the sector-shaped part. Simultaneously, cylindrical pins on the left and right sides of the perforated plate engage with holes on the left and right sides of the part to constrain the plate's position, thus ultimately determining the punching point position. The addition of a bushing and spring element to the perforated plate makes the punching process more stable. This effectively solves the problem of poor circumferential position consistency when the operator visually selects the punching point position, and requires less skill from the operator. It prevents problems such as chamfering, damage, and deformation of the hole opening caused by careless operation, and also prevents the quality hazard of the punch slipping and scratching the part surface.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
