Description

Technical Field

[0001] The invention relates to the technical field of shaping tooling, and in particular to an assembly shaping tooling and an assembly method for satellite lens barrel blade ribs. Background Art

[0002] The description of the background technology in the present invention belongs to the related technology related to the present invention, which is only used to illustrate and facilitate the understanding of the invention content of the present invention, and should not be understood as the applicant explicitly believes or inferred that the applicant believes that it is the prior art of the present invention on the filing date of the first application.

[0003] C / SiC composite materials have the advantages of low density, high strength, high temperature resistance, wear resistance, corrosion resistance, high toughness, and oxidation resistance. The forming method of C / SiC composite parts is: the carbon fiber cloth is sewn on the mold with carbon fiber bundles, and the carbon fiber cloth is continuously densified by chemical vapor deposition (CVI) method, so that the carbon fiber cloth is continuously hardened and gradually forms the required part shape. Therefore, C / SiC composite parts are generally thin-walled parts.

[0004] The blade ribs in the satellite C / SiC lens barrel components include support arms and blade rib arc plates, which are formed by continuously densifying carbon fiber cloth using the chemical vapor deposition (CVI) method. After the blade rib support arms and blade rib arc plates are assembled into the blade rib as a whole, vapor deposition needs to be performed again. Considering that the blade rib support arms and blade rib arc plates are thin-walled parts, they are easy to deform under the action of pressure, and the thin wall thickness of the parts is easy to vibrate under the action of cutting force. Therefore, when assembling the blade ribs together, a certain amount of force needs to be applied during the assembly process to ensure the assembly accuracy. However, in the existing assembly and molding process, there is a lack of tooling to assist in the calibration, which affects the accuracy of the blade rib assembly and subsequent molding. Summary of the invention

[0005] The purpose of the present invention is to provide an assembly and profiling tool and an assembly method for satellite lens barrel blade ribs, so as to solve the problem that existing C / SiC composite thin-walled parts lack tooling for auxiliary profiling, thereby affecting the assembly accuracy.

[0006] The technical solution of the present invention to solve the above technical problems is as follows:

[0007] A tool for assembling and profiling satellite lens barrel blade ribs, comprising a mounting platform and a positioning sleeve, a first arm shaping assembly, a second arm shaping assembly, and a third arm shaping assembly arranged on the mounting platform; the positioning sleeve comprises a fixed cylinder and a limiting cylinder arranged on the top of the fixed cylinder, and the limiting cylinder is detachably connected to the fixed cylinder; the first arm shaping assembly, the second arm shaping assembly, and the third arm shaping assembly are respectively arranged at intervals along the circumferential direction of the fixed cylinder; the first arm shaping assembly, the second arm shaping assembly, and the third arm shaping assembly all comprise an arm clamping assembly for supporting a blade rib arm and an arc limiting assembly for limiting an arc plate of the blade rib.

[0008] The beneficial effects of adopting the above technical solution are as follows: the leaf rib as a whole includes three arms and three leaf rib circular plates, a single arm includes two arms connected to each other, an angle is set between the two arms, the arms of the three leaf ribs are fitted in pairs and connected to a leaf rib circular plate respectively, the leaf rib circular plate and the arm are separate structures, so the installation accuracy of the arm and the leaf rib circular plate affects the forming accuracy of the leaf rib as a whole. The fixed cylinder is installed on the installation platform, the limit cylinder is connected to the fixed cylinder, the leaf rib circular plate is set at the corresponding position, the tops of the three leaf ribs are respectively connected to the limit cylinder to form a circular ring, and the bottoms of the arms are respectively connected to the corresponding leaf rib circular plates. The circular arc limit assemblies are respectively fitted with the corresponding leaf rib circular plates, and the arm clamping assemblies clamp the corresponding arms. At this time, the various parts of the leaf rib as a whole are in a relatively fixed state, and then the limit cylinder is disassembled to install the fixed circular ring, and finally the leaf rib as a whole and the tooling are subjected to meteorological deposition.

[0009] This shaping tooling can not only assemble the support arms and arc plates of the blade ribs, facilitating installation, but also improve the assembly accuracy of the blade ribs. Since the assembled blade ribs are still subject to subsequent vapor deposition treatment, deformation of the components will occur during the vapor deposition process. This tooling can be used for vapor deposition together with the blade ribs as a whole, effectively preventing deformation of the components during the chemical vapor deposition process, thereby increasing the qualified rate of finished components and further improving the forming accuracy of the blade ribs. Secondly, the blade ribs need to be fine-machined after vapor deposition. This tooling also plays a role in clamping, positioning and supporting in the fine-machining of the blade ribs, thereby reducing machining damage and improving machining accuracy.

[0010] Furthermore, the mounting platform is provided with a slot for clamping the arc limit assembly, the arc limit assembly includes a mounting block and an arc limit block arranged on the top of the mounting block, the mounting block is arranged in the slot; the arc concave surface of the arc limit block faces the support arm clamping assembly.

[0011] The beneficial effects of adopting the above technical solution are: the push installation block is installed in the slot, and the arc limit block abuts against the side wall of the leaf rib arc plate, thereby limiting the leaf rib arc plate, and then the corresponding support arm is installed. Since there is an angle between the support arms of a single leaf rib, when the support arms of each leaf rib are fitted and connected to the corresponding arc plate, the position of the arc plate needs to be determined first. This technical solution limits the leaf rib arc plate by setting an arc limit block to ensure the connection accuracy between the support arm and the leaf rib arc plate.

[0012] Furthermore, a support arm tail limit assembly is provided on the top of the mounting block, and the support arm tail limit assembly includes a support platform and an support arm limit block arranged on the top of the support platform, and there is a gap between the end of the support arm limit block close to the support arm clamping assembly and the arc concave surface of the arc limit block and an arm limit groove is provided, and the support platform, the mounting block and the mounting platform are connected by a first fastener.

[0013] Furthermore, a first cushion block is provided on the side wall of the support arm limiting groove.

[0014] The beneficial effects of adopting the above technical solution are as follows: after the support arm is connected to the blade rib arc plate, the blade rib arc plate is limited by the arc limit assembly, and the support arm is located in the support arm limit groove. At this time, the support platform is installed on the mounting block, and the first pad fills the gap between the support arm limit groove and the support arm. This technical solution takes into account that the support arm and the blade rib arc plate are split structures. After the support arm is connected to the blade rib arc plate, the connection between the support arm and the blade rib arc plate is limited by the support arm tail limit assembly to avoid displacement after the support arm is connected to the blade rib arc plate, and also to avoid deformation of the connection during subsequent vapor deposition.

[0015] Furthermore, the arm clamping assembly includes a first right-angle frame and a second right-angle frame that are symmetrically and spaced apart, the bottoms of the first right-angle frame and the second right-angle frame are respectively connected to the mounting platform through second fasteners, and the tops of the first right-angle frame and the second right-angle frame are respectively provided with third fasteners for connecting the leaf rib arms.

[0016] Furthermore, the side walls corresponding to the first right-angle frame and the second right-angle frame are respectively provided with second cushion blocks.

[0017] The beneficial effect of adopting the above technical solution is: the first right angle bracket and the second right angle bracket are respectively arranged on both sides of the support arm and connected to the support arm by a third fastener, so as to limit and fix the middle part of the support arm. Since the support arm has a certain length and is arranged obliquely, the support arm clamping assembly can provide a certain support force to the middle part of the support arm, prevent the two ends of the workpiece from deviating, and ensure the assembly accuracy between the leaf ribs and between the support arm and the leaf rib arc plate.

[0018] Furthermore, a fixing assembly for fixing the blade rib arc plate is arranged between the support arm clamping assembly and the arc limit assembly, and the fixing assembly includes a first pressure plate and a second pressure plate respectively used to fix the two ends of the blade rib arc plate, and the first pressure plate and the second pressure plate are respectively connected to the mounting platform through a fourth fastener.

[0019] The beneficial effects of adopting the above technical solution are as follows: after the arc limit assembly is fitted with the blade rib arc plate, the first pressure plate and the second pressure plate are respectively installed at both ends of the blade rib arc plate to limit the two ends of the blade rib arc plate. When it is necessary to adjust the installation position of the support arm and the blade rib arc plate, the position of the blade rib arc plate is adjusted by loosening the fourth fastener. The blade rib arc plate has an arc surface. The arc limit assembly and the support arm clamping assembly of the technical solution are used in combination, which can not only limit the blade rib arc plate, but also the position of the blade rib arc plate is not easy to be displaced after the installation position of the blade rib arc plate is determined.

[0020] Furthermore, the mounting platform is embedded with an indicating limit block for indicating the placement position of the blade rib arc plate.

[0021] An assembly method for an assembly and profiling tool for satellite lens barrel blade ribs, the method comprising the following steps:

[0022] S1: After placing the blade rib arc plate at the corresponding position, the top of a single blade rib support arm is fitted with the limiting cylinder, the fitting part between the top of the support arm and the limiting cylinder is polished, and the tail of the blade rib support arm is connected with the corresponding blade rib arc plate;

[0023] S2: Install the remaining two leaf ribs in sequence, so that the tops of the three leaf rib arms form a ring, and the three leaf rib arms fit in pairs;

[0024] S3: Install the arc limit assembly on the installation platform, so that the inner side of the arc limit assembly fits with the side wall of the blade rib arc plate;

[0025] S4: Use three-coordinate measurement to detect the angle between the individual rib arms to ensure that the angle meets the tolerance requirements;

[0026] S5: Install the arm clamping assembly between the fixed cylinder and the arc limit assembly;

[0027] S6: Remove the limiting cylinder from the fixed cylinder, install the fixed ring in the circular ring, and connect the fixed ring and the corresponding blade rib support arm in sequence through pins;

[0028] S7: chemical vapor deposition is performed on the assembled blade rib as a whole and on the tooling.

[0029] Furthermore, step S1 also includes installing angle materials on the top of each leaf rib support arm, and installing back plates for clamping the corresponding support arms on the side of the leaf rib arc plate away from the arc limit assembly.

[0030] The present invention has the following beneficial effects:

[0031] The present invention can not only assemble the support arms and the arc plates of the blade ribs, facilitating installation, but also improves the assembly accuracy of the blade ribs. Since the assembled blade ribs are still subject to subsequent vapor deposition treatment, deformation of the components will occur during the vapor deposition process. The present tooling can be used for vapor deposition together with the blade ribs as a whole, effectively preventing deformation of the components during the chemical vapor deposition process, thereby improving the qualified rate of finished components and further improving the forming accuracy of the blade ribs. Secondly, the blade ribs need to be fine-machined after vapor deposition. The present tooling also plays a role in clamping, positioning and supporting in the fine-machining link of the blade ribs, thereby reducing machining damage and improving machining accuracy.

[0032] The present invention takes into account that the support arm and the blade rib arc plate are split structures. When the support arm is connected to the blade rib arc plate, the connection between the support arm and the blade rib arc plate is limited by the support arm tail limiting assembly to avoid displacement after the support arm and the blade rib arc plate are connected, and to avoid deformation of the connection during subsequent vapor deposition.

[0033] The circular arc limiting assembly and the support arm clamping assembly of the present invention are used in combination, which can not only limit the position of the blade rib circular arc plate, but also prevent the position of the blade rib circular arc plate from being easily displaced after the installation position of the blade rib circular arc plate is determined.

DETAILED DESCRIPTION

[0041] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0042] Please refer to Figure 5 The rib in the present invention comprises three arms and three rib circular arc plates 602. A single arm comprises two rib arms 601. The angle between the two rib arms 601 is 120°. The tops of the two rib arms 601 are connected by an arc segment, and the bottoms of the two rib arms 601 are tilted downward. The three ribs are bonded together. Each rib arm 601 is processed with a corresponding pin hole. The bonded rib arms 601 are connected by pins. The bottoms of the bonded rib arms 601 are connected with a rib circular arc plate 602. The two sides of the rib circular arc plate 602 are arc surfaces. The two ends of the rib circular arc plate 602 are tilted upward at a certain angle. After the three ribs are fitted together, the arc segment at the top of the rib support arm 601 forms a ring, and a fixing ring 604 is arranged inside the ring. An angle piece 603 is fitted to each rib support arm 601 and the arc segment respectively. The angle piece 603 is processed with a pin hole and is connected to the fixing ring 604 and the corresponding arc segment through a pin.

[0043] Please refer to Figure 1, an assembly and profiling tool for satellite lens barrel blade ribs, comprising an installation platform 1 and a positioning sleeve 2, a first arm shaping component 31, a second arm shaping component 32, and a third arm shaping component 33 arranged on the installation platform 1; the positioning sleeve 2 comprises a fixed cylinder 201 and a limiting cylinder 202 arranged on the top of the fixed cylinder 201, and the limiting cylinder 202 is detachably connected to the fixed cylinder 201 through a pin; the first arm shaping component 31, the second arm shaping component 32, and the third arm shaping component 33 are respectively arranged at intervals along the circumferential direction of the fixed cylinder 201. The first arm shaping component 31, the second arm shaping component 32, and the third arm shaping component 33 respectively limit the blade rib arm 601 and the corresponding blade rib circular arc plate 602 after bonding. This shaping tooling can not only assemble the blade rib support arm 601 and the blade rib arc plate 602 of the blade rib, facilitating installation, but also improves the assembly accuracy of the blade rib. Since the assembled blade rib needs to undergo subsequent vapor deposition treatment, the various components will still be deformed during the vapor deposition process. This tooling can be used for vapor deposition together with the blade rib as a whole, effectively preventing the components from being deformed during the chemical vapor deposition process, thereby increasing the qualified rate of finished components and further improving the forming accuracy of the blade rib. Secondly, the blade rib needs to be fine-machined after vapor deposition. This tooling also plays a role in clamping, positioning and supporting in the fine-machining stage of the blade rib, thereby reducing machining damage and improving machining accuracy.

[0044] Please refer to Figure 2 The mounting platform 1 is embedded with an indicating limit block 102 for indicating the placement position of the blade rib arc plate 602. The indicating limit block 102 is a block processed with an arc. The indicating limit block 102 is embedded in the mounting platform 1. The two ends of the indicating limit block 102 are connected to the mounting platform 1 through pins. Considering that the present invention is provided with three blade rib arc plates 602, three limit blocks are provided in this embodiment, and the angles between the limit blocks match the angles between the blade rib arc plates 602. The mounting platform 1 is provided with a card slot 101, and the number of the card slots 101 is 3. One end of the card slot 101 extends to the side wall of the mounting platform 1, and the other end of the card slot 101 extends to the limit block. The three card slots 101 are provided in a one-to-one correspondence with the three limit blocks.

[0045] The first arm shaping assembly 31 , the second arm shaping assembly 32 and the third arm shaping assembly 33 all include an arm clamping assembly 301 and an arc limiting assembly 302 for limiting the blade rib arc plate 602 . The arc limiting assembly 302 is arranged along the axial extension direction of the blade rib arm 601 .

[0046] Please refer to 1 and Figure 3The arc limit assembly 302 includes a mounting block 321 and an arc limit block 322 disposed on the top of the mounting block 321. The mounting block 321 is disposed in the slot 101. In this embodiment, the mounting block 321 and the arc limit block 322 are an integrated structure. The inner side of the arc limit block 322 is processed with an arc surface, which matches the shape of the leaf rib arc plate 602. The mounting block 321 is pushed to be installed in the slot 101, and the arc limit block 322 abuts against the side wall of the leaf rib arc plate 602, thereby limiting the leaf rib arc plate 602. At this time, the corresponding leaf rib support arm 601 is installed. Since there is an angle between the rib support arms 601 of a single rib, when the rib support arms 601 of each rib are fitted and connected to the corresponding arc plate, the position of the arc plate needs to be determined first. The present invention limits the rib arc plate 602 by setting an arc limit block 322 to ensure the connection accuracy between the rib support arms 601 and the rib arc plate 602.

[0047] A fixing assembly 5 for fixing the blade rib arc plate 602 is provided between the support arm clamping assembly 301 and the arc limiting assembly 302. The fixing assembly 5 includes a first pressing plate 501 and a second pressing plate 502 respectively provided at both ends of the blade rib arc plate 602. The first pressing plate 501 and the second pressing plate 502 are respectively connected to the mounting platform 1 through a fourth fastener 503. After the arc limiting assembly 302 is fitted with the blade rib arc plate 602, the first pressing plate 501 and the second pressing plate 502 are respectively installed at both ends of the blade rib arc plate 602 to limit the two ends of the blade rib arc plate 602. When it is necessary to adjust the installation position of the blade rib support arm 601 and the blade rib arc plate 602, the fourth fastener 503 is loosened to adjust the position of the blade rib arc plate 602. The blade rib arc plate 602 has an arc surface. The arc limiting component 302 and the support arm clamping component 301 of the present invention are used in combination, which can not only limit the blade rib arc plate 602, but also prevent the position of the blade rib arc plate 602 from being easily displaced after the installation position of the blade rib arc plate 602 is determined.

[0048] The limiting assembly process of the leaf rib arc plate 602: 1) Place the leaf rib arc plate 602 in the corresponding limiting block, and after the arc segment of the top of each leaf rib fits with the fixed cylinder 201, the fitted leaf rib support arm 601 is connected to the corresponding leaf rib arc plate 602. The leaf rib support arm 601 is connected with a pin and preliminarily fixed with a bow clamp; 2) The movable installation block 321 moves in the slot 101 until the arc surface of the arc limiting block 322 fits with the arc surface of the leaf rib arc plate 602, and the first pressure plate 501 and the second pressure plate 502 are respectively installed at both ends of the leaf rib arc plate 602 and the fourth fastener 503 is tightened; 3) When the installation of the leaf rib support arm 601 does not meet the tolerance requirements, the fourth fastener 503 is screwed in, and the position of the leaf rib arc plate 602 and the leaf rib support arm 601 is adjusted.

[0049] Please refer to Figure 4The arm clamping assembly 301 includes a first right angle frame 311 and a second right angle frame 312 symmetrically arranged on both sides of the leaf rib arm 601. The bottoms of the first right angle frame 311 and the second right angle frame 312 are respectively connected to the mounting platform 1 through second fasteners 313, and the tops of the first right angle frame 311 and the second right angle frame 312 are respectively connected to the corresponding leaf rib arm 601 through third fasteners 314. A second cushion block 315 is respectively arranged between the first right angle frame 311 and the second right angle frame 312 and the leaf rib arm 601. The second cushion block 315 is processed with a pin hole, which matches the pin of the leaf rib arm 601 after connection and bonding. This arrangement is to allow gas to flow around the pin hole during chemical vapor deposition, so that the pin can be effectively deposited. The first right angle bracket 311 and the second right angle bracket 312 are respectively arranged on both sides of the leaf rib support arm 601 and connected to the leaf rib support arm 601 by the third fastener 314, so as to limit and fix the middle part of the leaf rib support arm 601. Since the leaf rib support arm 601 has a certain length and is arranged obliquely, the arm clamping assembly 301 can provide a certain support force to the middle part of the leaf rib support arm 601, prevent the two ends of the workpiece from deviating, and ensure the assembly accuracy between the leaf ribs and between the leaf rib support arm 601 and the leaf rib arc plate 602.

[0050] Please refer to 1 and Figure 3A support arm tail limit assembly 4 is provided on the top of the mounting block 321, and the support arm tail limit assembly 4 includes a support platform 401 and an arm limit block 402 arranged on the top side wall of the support platform 401 and facing the leaf rib support arm 601. The support platform 401 is L-shaped, and the bottom of the support platform 401 is in contact with the mounting block 321, and the inner side of the support platform 401 is in contact with the arc limit block 322. The support arm limit block 402 has a certain length, and a clearance groove for avoiding the arc limit block 322 is provided at the bottom of the support arm limit block 402. There is a gap between one end of the support arm limit block 402 close to the support arm clamping assembly 301 and the concave surface of the arc surface of the arc limit block 322, and an arm limit groove 421 is provided. The support platform 401, the mounting block 321 and the mounting platform 1 are connected in sequence through the first fastener 403. A first cushion block 404 is respectively arranged between the arm limiting groove 421 and the side wall of the tail of the rib arm 601. When the rib arm 601 is connected to the rib circular arc plate 602, the rib circular arc plate 602 is limited by the circular arc limiting assembly 302, and the rib arm 601 is located in the arm limiting groove 421. At this time, the support platform 401 is installed on the mounting block 321, and the first cushion block 404 fills the gap between the arm limiting groove 421 and the rib arm 601. The present invention takes into account that the rib arm 601 and the rib circular arc plate 602 are split structures. When the rib arm 601 is connected to the rib circular arc plate 602, the connection between the rib arm 601 and the rib circular arc plate 602 is limited by the arm tail limiting assembly 4, so as to avoid displacement after the rib arm 601 is connected to the rib circular arc plate 602, and also to avoid deformation of the connection during subsequent vapor deposition. It is worth noting that, in this embodiment, the first fastener 403, the second fastener 313, the third fastener 314 and the fourth fastener 503 are all bolts.

[0051] The limiting assembly process of the leaf rib support arm 601: 1) After the position of the leaf rib arc plate 602 is fixed, the angle material 603 is installed on the arc section at the top of the leaf rib support arm 601; 2) The installation positions of the first right-angle bracket 311 and the second right-angle bracket 312 are respectively determined on both sides of the leaf rib support arm 601 after bonding. Since a pin is installed between the leaf rib support arm 601 after bonding, if the pin is too long, it is polished; 3) The second cushion block 315 is installed on the inner side of the first right-angle bracket 311 and the second right-angle bracket 312, and the second fastener 313 and the third fastener 314 are tightened; 4) The support arm limiting groove 421 is aligned with the leaf rib support arm 601 after bonding, so that the leaf rib support arm 601 is located in the middle position of the support arm limiting groove 421, and the first cushion block 404 is placed on both sides of the leaf rib support arm 601 to prevent the leaf rib support arm 601 from offsetting in the support arm limiting groove 421.
