Description

Technical Field

[0001] This invention relates to the field of tooling and fixture equipment technology, and in particular to a clamping system for positioning and adjusting the orientation of large cylindrical main structural components. Background Technology

[0002] In the machining of a large cylindrical main structural component, positioning, clamping, and flipping are crucial steps. The process generally consists of three stages: First, the back-facing part is placed on a fixture, positioned, and clamped before machining begins. Second, the large cylindrical main structural component is flipped 180° along its axis. Third, the belly-facing part is positioned and positioned before machining begins. Traditional clamping methods use two sets of fixtures to accommodate different machining states of the large cylindrical main structural component. After one machining state is completed, the part must be hoisted onto the other set of fixtures, and the positioning and adjustment process requires a worker to lift the part with slings and manually crank it. This method has low automation and using two sets of fixtures is cumbersome, significantly impacting machining efficiency.

[0003] Currently, clamping devices for large cylindrical main structural components have largely solved problems such as low positioning and attitude adjustment efficiency. However, due to the immaturity of current automated clamping and attitude adjustment technology, there is still no unified automated assembly scheme. Existing clamping and attitude adjustment device patents have the following problems: The small missile section docking fixture disclosed in CN10795306A can achieve fine-tuning of missile elevation, lateral adjustment, and axial force application, but cannot adjust the pitch, yaw, and roll motion of the section; a six-degree-of-freedom attitude adjustment platform and method for missile tube docking disclosed in CN114932517A can solve the pitch, yaw, and roll attitude adjustment of cylindrical parts, but cannot perform 180° rotation of cylindrical parts; a support method for assembling, adjusting, and positioning aircraft fuselage components disclosed in CN111977018A can adjust the attitude of cylindrical aircraft fuselage components, but cannot clamp cylindrical parts.

[0004] Therefore, for the automated clamping and orientation adjustment of large cylindrical main structural components, it is crucial to research a clamping device that can achieve automatic positioning, orientation adjustment, and automatic flipping. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention provides a clamping system for positioning and adjusting the orientation of large cylindrical main structural components.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The clamping system for positioning and adjusting large cylindrical main structural components provided by this invention, wherein the clamping device, through a first clamping device and a second clamping device, enables clamping of the large cylindrical main structural component in two different machining states on the same set of fixtures. Addressing the different tool interference areas in different machining states, the operator can quickly disassemble or install clamping rings to reconstruct the clamping envelope surface without replacing the entire set of tooling. This overcomes the limitation of traditional tooling being only applicable to a single machining state, ensuring interference avoidance during machining while significantly reducing auxiliary time and tooling costs caused by state switching.

[0017] 2. The clamping system for positioning and adjusting large cylindrical main structural components provided by this invention integrates a first clamping device, a second clamping device, a clamping ring drive roller, a servo motor, and a reducer to form an active collaborative flipping system. When a processing state is completed, the system controls the servo motors of the first and second clamping devices to synchronously drive the drive rollers inside the clamping ring base, causing the clamping ring and internal cylindrical sections to rotate 180° around the horizontal axis. A spring plunger driven by a cylinder engages with the stop on the clamping ring locking plate to achieve rigid mechanical locking. During the flipping process, the cylindrical sections are always clamped by the clamping ring, eliminating the need for manual intervention, crane assistance, or secondary clamping and alignment. This solves the problems of high safety risks, low efficiency, and easy damage to the surface of parts associated with manual or crane-assisted flipping of large cylindrical main structural components, significantly improving processing cycle time and automation level.

[0018] 3. The clamping system for positioning and attitude adjustment of large cylindrical main structural components provided by this invention addresses the challenge of positioning and attitude adjustment before machining large cylindrical main structural components. It constructs a distributed automatic attitude adjustment system consisting of a front-end adjustment device, an intermediate adjustment device, a positioning device, and a limiting device. The front-end adjustment device, through a ball joint support driven by a servo motor and a cross-hing structure, performs pitch and roll adjustment when the cylindrical section is in a back-up position. It also performs yaw adjustment when the part is in a back-up position using a push plate of a double-rod cylinder, ensuring that the front end of the part does not rotate relative to the clamping ring during rotation. The intermediate adjustment device, through an axial movement mechanism, a lifting mechanism, a yaw adjustment mechanism, and a rotation adjustment mechanism, provides combined adjustment of axial, pitch, yaw, and roll multiple degrees of freedom for the central area of ​​the cylindrical section when it is in a back-up position. The positioning device and the limiting device provide an initial reference and axial safety boundary for attitude adjustment. The above devices work together to achieve automatic alignment and closed-loop attitude control of the cylindrical section in both machining states. Compared to traditional manual posture adjustment methods, this invention eliminates manual operation, improves the accuracy, repeatability and efficiency of the posture adjustment process, and significantly reduces the labor intensity of operators.

[0019] 4. The clamping system for positioning and adjusting large cylindrical main structural components provided by this invention has a positioning device on the front side of the first clamping device and a limiting device on the rear side of the second clamping device. The positioning device provides an initial reference before adjustment; during the clamping and adjustment of the cylindrical section, the limiting device prevents the cylindrical section from detaching from the clamping ring area due to accidental axial movement, thus providing a mechanical hard limiting effect. To avoid interference during part flipping, both the positioning device and the limiting device have telescopic and rotational functions, avoiding errors caused by repeated disassembly and installation. Simultaneously, the spring plunger driven by the cylinder engages with the stop on the clamping ring locking plate, achieving rigid locking after the clamping ring is flipped into position, further ensuring the stability and safety of clamping under cutting conditions.

Driven by the lifting motor 430, the inclined wedge platforms 426 on both sides of the bottom of the lifting platform 428 move in opposite directions along the lifting slide rail 429. At this time, the first slide 425 and the second slide 427 slide relative to each other, and the lifting platform 428 moves up and down along the lifting side plate 422, thereby realizing the lifting of the lifting unit 42.

Located in the middle of the second retaining ring base 512, the second lower retaining ring 508 is supported on the second retaining ring base 512 by the second rotating roller 509 and the second support roller 510. Multiple second pressure roller modules 504 are evenly distributed on both sides of the second retaining ring base 512, and the second lower retaining ring 508 is pressed against the second rotating roller 509 and the second support roller 510 by the multiple second pressure roller modules 504.

The top of the second upper retaining ring 501 is provided with an arc-shaped guard plate 514, and a disassembly retaining ring 515 is provided above the arc-shaped guard plate 514. 01 is positioned above the second lower clamping ring 508.

After the infrared window 72 at the back of the second end of the cylinder section 7 is processed, when it is necessary to rotate to the belly-up position, the disassembly clamping ring 515 is installed on the second upper clamping ring 501. At this time, the second motor 511 drives the rotation of the second rotating roller 509 and the second supporting roller 510 to rotate the cylinder section 7, thereby achieving a 180° rotation of the cylinder section 7. The second cylinder 507 is positioned above the second clamping ring. Above the first end of the ring base 512, and on the second cylinder 507, there is a second spring plunger 506. The second locking plate 503 is symmetrically arranged at both ends of the second ring base 512. During the rotation of the second upper ring 501 and the second lower ring 508, the second cylinder 507 extends, and the second spring plunger 506 contacts the second upper ring 501. When the positioning pin of the second spring plunger 506 is fully inserted into the positioning hole of the second upper ring 501, it can be determined that the 180° rotation of the cylinder section 7 is completed. At this time, the second locking plate 503 fixes the second lower ring 508, which is rotated to the locking position, that is, the appropriate position, through the locking port on the second lower ring 508, so as to achieve rigid locking.

[0034] like Figure 9As shown, the limiting device 6 includes a limiting strip 601, a limiting strip support 602, a limiting telescopic rod 603, a limiting connecting square tube 604, a limiting pressure plate 605, a limiting connecting plate 606, and a limiting bottom square tube 607.

The limiting pressure plate 605 is fixed to the first end of the limiting connecting square tube 604. When the limiting connecting square tube 604 rotates... During the process, when the limiting pressure plate 605 is in horizontal contact with the limiting bottom square tube 607, it can be determined that the limiting connecting square tube 604 has rotated to the limiting position. At this time, the limiting pressure plate 605 is used to connect the limiting connecting square tube 604 and the limiting bottom square tube 607 through the limiting fastener 608. The first end of the limiting telescopic rod 603 is slidably disposed on the second end of the limiting connecting square tube 604, and the second end of the limiting telescopic rod 603 is fixed at two different heights on the limiting connecting square tube 604 through the limiting locking member 609. The second end of the limiting telescopic rod 603 is provided with a limiting strip support 602, and the first end of the limiting strip 601 is disposed on the limiting strip support 602. The limiting bar 601 uses the stop inside the cylindrical section 7 to limit the circumferential rotation of the cylindrical section 7. Before the first clamping device 1 and the second clamping device 5 rotate the cylindrical section 7, the positioning device 3 lowers its height and rotates 90° to prevent interference with the cylindrical section 7 during rotation. Specifically, the limiting telescopic rod 603 descends inside the limiting connecting square tube 604, and then the limiting connecting square tube 604 rotates 90° relative to the limiting bottom square tube 607.

[0035] like Figures 10-12 As shown, section 7 is divided into two processing states: back-facing and belly-facing.

[0036] This invention provides a clamping system for positioning and adjusting the orientation of large cylindrical main structural components, such as... Figures 1-12 As shown, an automated tooling fixture with a high degree of automation is provided, which integrates two sets of tooling fixtures into one, can automatically rotate the cylinder section 7 by 180°, and improves the efficiency of the cylinder section 7's orientation adjustment process. The specific implementation process is as follows: S1: The first clamping device 1 and the second clamping device 5 are capable of clamping the cylindrical section 7 in two states: with its belly facing up and its back facing up. They also have the function of rotating the front end of the cylindrical main structural component along the central axis. When the cylindrical section 7 is in the back-facing state, it is placed above the first lower clamping ring 108 and the second lower clamping ring 508. After the cylindrical section 7 is adjusted and positioned by the front adjustment device 2 and the positioning mechanism device 3, the first upper clamping ring 101 and the first lower clamping ring 108 in the first clamping device 1, and the second upper clamping ring 501 and the second lower clamping ring 508 in the second clamping device 5 are fixed by the locking plate to complete the clamping of the cylindrical section 7. After the cylindrical section 7 is processed in the back-facing state, the first motor 111 and the second motor 511 drive the rotating roller to rotate the cylindrical section 7 by 180° to adapt to the processing area when the cylindrical section 7 is facing up. At this time, the intermediate adjustment device 4 and the positioning device 3 are used to adjust and position the cylindrical section 7.

[0037] S2: The front-end adjustment device 2 has the functions of pitching, yawing, and rolling adjustment of the cylinder section 7 when it is in the back-facing position, and preventing relative rotation between the cylinder section 7 and the retaining ring during rotation. When the cylinder section 7 is in the back-facing position and is placed on the support retaining ring 516 above the first lower retaining ring 108 and the second lower retaining ring 508, after the cylinder section 7 reaches the axial limit, the push plate 205 rises and falls with the extension and retraction of the intermediate electric cylinder 209, thereby realizing the pitch adjustment of the cylinder section 7. The push plate 205 rotates at a small angle around the intermediate vertical electric cylinder 208 with the extension and retraction of the left and right vertical electric cylinders 208, thereby realizing the small-angle roll adjustment of the cylinder section 7. The double-rod cylinder 201 extends and presses against the inner side of the cylinder section 7 to realize the yaw adjustment of the cylinder section 7.

[0038] S3: The positioning mechanism device 3 has the functions of lifting, rotating, and positioning using the front stop of the cylindrical section 7. When the cylindrical section 7 is placed on the ring of the first clamping device 1 and the second clamping device 5, the positioning stop 71 on the first end of the cylindrical section 7 completes the circumferential rotation positioning of the cylindrical section 7. Before the first clamping device 1 and the second clamping device 5 rotate the cylindrical section 7, the positioning mechanism device 3 lowers its height and rotates 90° to prevent interference to the cylindrical section 7 during the rotation. Specifically, the positioning telescopic rod 303 descends inside the positioning connecting square tube 304, and then the positioning connecting square tube 304 rotates 90° relative to the positioning connecting square tube 304.

[0039] S4: The intermediate adjustment device 4 has the function of pitching, yawing and rolling the cylinder section 7 when it is in the back-facing position. When the cylinder section 7 is placed above the first lower retaining ring 108 and the second upper retaining ring 501 in the belly-facing position, the lifting unit 42 lifts the cylinder section 7 away from the retaining ring, and the axial movement unit 41 makes the cylinder section 7 reach the axial limit position. The pitch adjustment of the cylinder section 7 is achieved by the height difference between the front and rear lifting units 42, and the yaw adjustment of the cylinder section 7 is achieved by the yaw adjustment unit 43.

[0040] S5: The limiting mechanism 6 has the functions of lifting, rotating, and limiting the cylinder section 7 using the rear end face. The limiting bar 601 uses the rear end face inside the cylinder section 7 to limit the cylinder section 7 axially. Before the first clamping device 1 and the second clamping device 5 rotate the cylinder section 7, the limiting mechanism device 6 reduces its height and rotates 90° to prevent interference to the cylinder section 7 during rotation. Specifically, the limiting telescopic rod 603 descends inside the limiting connecting square tube 604, and then the limiting connecting square tube 604 rotates 90° relative to the limiting bottom square tube 607.
