Description

Technical Field

[0001] This invention relates to the field of automotive processing technology, specifically a roller edge fixture for welding automotive side panels. Background Technology

[0002] As a key component of the vehicle body structure, the machining accuracy and assembly quality of the automotive side panel directly affect the overall vehicle's appearance flatness, structural strength, and safety performance. Welding and roll edge processing are the core processes in automotive side panel forming. These processes require specialized roll edge fixtures to position and clamp the side panel workpiece, ensuring no displacement or deformation during processing and meeting the dual requirements of high-precision machining and large-scale production. With the development of personalized and multi-model flexible production trends in the automotive industry, the shape contours and structural specifications of automotive side panels are becoming increasingly diverse, placing higher standards on the adaptability, adjustment flexibility, and clamping stability of the matching roll edge fixtures.

[0003] Existing automotive side panel welding roller edge fixtures mostly adopt a fixed structure or a simple adjustable structure design. During operation, the fixture base is usually fixed to the processing station, and the automotive side panel is clamped and positioned based on the preset fixed clamping points. Some simple adjustable fixtures can only achieve single linear displacement adjustment of the clamping components. The clamping position is roughly adjusted by manually turning bolts, buckles and other components. Then, the workpiece is pressed with the help of a clamping plate of fixed specifications, and then welding and roller edge processing operations are carried out.

[0004] Existing roller edge clamps of this type have many technical defects in practical applications. First, the clamping point adjustment range is limited, and they can only be adapted to a single car model or a few specifications of car side panels. They are extremely unsuitable for side panel workpieces with irregular curved surfaces and different thicknesses. Production of multiple car models requires the customization of multiple special clamps, which greatly increases production and replacement costs. Second, the height, angle and contact shape of the clamping components cannot be precisely adjusted, making it difficult to fit the complex structure of the side panel and easily leading to problems such as unstable clamping, workpiece damage or deformation.

[0005] Therefore, it is necessary to provide a roller edge fixture for welding automotive side panels to solve the above-mentioned technical problems. Summary of the Invention

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] Please see Figures 1-3 and Figures 6-10In this embodiment of the invention, a roller edge fixture for welding automotive side panels includes a base 1, multiple guide rails 2 fixedly mounted on the upper surface of the base 1, multiple mounting brackets 3 slidably mounted on the guide rails 2, a sliding assembly 4 slidably disposed on the top of the mounting brackets 3, and a clamping assembly 6 disposed above the sliding assembly 4. The sliding direction of the mounting brackets 3 on the guide rails 2 is perpendicular to the sliding direction of the sliding assembly 4 on the mounting brackets 3. Multiple locking bolts 8 are threadedly installed on the bottom of the mounting brackets 3, and the bottom ends of the locking bolts 8 are in contact with the upper surface of the base 1. The locking bolts 8 are used to lock the mounting brackets 3. The clamping assembly 6 includes a lower clamping plate 601, an upper clamping plate 602 hinged to the lower clamping plate 601, and a driving component for driving the upper clamping plate 602 to rotate. Multiple mounting grooves 604 are formed on the opposing surfaces of the upper clamping plate 602 and the lower clamping plate 601, and multiple mounting grooves 604 are provided in the multiple mounting grooves 604. The clamping module 605 includes a lifting plate 6051, a concave seat 6052 fixedly installed on the upper surface of the lifting plate 6051, a mounting seat 6054 rotatably installed inside the concave seat 6052, multiple support blocks 6055 fixedly installed on the mounting seat 6054, and a locking component for locking the mounting seat 6054. The lifting plate 6051 is slidably installed in the mounting groove 604. When the roller edge clamp is used, the car side panel is transferred to the top of the base 1 by a robot arm. The upper clamping plate 602 is driven to rotate by the driving component, so that the car side panel is clamped by the upper clamping plate 602 and the lower clamping plate 601 to achieve rigid fixation of the car side panel, ensuring the positioning accuracy and processing stability of subsequent welding and roller edge processing, avoiding workpiece displacement and deformation that affect processing quality, and then the integrated processing of car side panel welding and roller edge processing can be carried out.

[0023] This solution utilizes the bidirectional vertical sliding arrangement of the sliding mounting bracket 3 and the sliding component 4 to achieve flexible adjustment of the clamping points in a horizontal two-dimensional plane. This allows for rapid adaptation to the clamping and positioning needs of automotive side panels with different contours and sizes, eliminating the need for customized clamps for individual vehicle models. The modularly arranged clamping modules 605 on the upper clamping plate 602 and lower clamping plate 601 enable precise adjustment of the height, contact shape, and clamping angle of the clamping points. Specifically, the sliding and lifting of the lifting plate 6051 within the mounting groove 604 fine-tunes the vertical height of the support block 6055, adapting to the side panel. Due to the different surface height differences and clamping gaps in different parts, each mounting base 6054 integrates multiple support blocks 6055 with different structures. By rotating the mounting base 6054, the type of support block 6055 can be quickly switched to adapt to the specific clamping conditions such as complex curved surfaces and irregular corners of the car side panel. This greatly expands the applicable scenarios and adaptation range of the clamping component 6. For car side panel clamping operations of different structures and car models, there is no need to replace the entire fixture body. Only the clamping module 605 needs to be adjusted to complete the adaptation, which significantly improves the versatility of the fixture and processing efficiency.

[0024] In this embodiment, preferably, the clamping module 605 further includes an adjusting screw 6056, which is threadedly connected to the lower clamping plate 601 or the upper clamping plate 602. The end of the adjusting screw 6056 extends into the mounting groove 604, and the adjusting screw 6056 passes through the lifting plate 6051 and is threadedly connected to the lifting plate 6051. When adjusting the height of the lifting plate 6051, the concave seat 6052 is first manually fixed so that it cannot move, and then the adjusting screw is loosened. Adjust screw 6056 to release the threaded locking engagement between the adjusting screw 6056 and the lifting plate 6051. Then, manually fine-tune the lifting plate 6051 vertically along the mounting groove 604 to the target height. After the height is adjusted to the correct position, retighten the adjusting screw 6056 to restore the threaded locking state between the adjusting screw 6056 and the lifting plate 6051, thereby achieving rigid positioning of the lifting plate 6051. This ensures the vertical height stability of the clamping module 605, prevents loosening and displacement during processing, and guarantees clamping accuracy.

[0025] In this embodiment, preferably, a rotating shaft 6053 is rotatably mounted on the concave seat 6052, and the mounting base 6054 is fixedly connected to the rotating shaft 6053; the locking component includes an adjusting plate 6057, a connecting plate 6058, and a locking plate 6059. A through groove 60521 is provided at the bottom of the concave seat 6052, and the end of the adjusting screw 6056 extends into the through groove 60521. The adjusting plate 6057 is slidably disposed within the through groove 60521 and penetrates the through groove 60521. Connecting plates 6058 are fixedly mounted on both sides of the upper surface of the adjusting plate 6057, and a locking plate 6059 is fixedly mounted on the top of each of the two connecting plates 6058. The locking plate 6059 has an arc-shaped structure; when locking the rotating shaft 6053, the locking plate 6059 presses against the rotating shaft 6053, and the adjusting... The end of the screw 6056 presses against the adjusting plate 6057. After the support block 6055 is selected and the clamping angle is adjusted, the adjusting screw 6056 is tightened. The axial thrust of the adjusting screw 6056 pushes the adjusting plate 6057, causing the adjusting plate 6057 to slide along the through groove 60521 toward the rotating shaft 6053. Then, the connecting plate 6058 drives the arc-shaped locking plate 6059 to move synchronously, so that the locking plate 6059 is tightly pressed against the outer wall of the rotating shaft 6053, realizing the locking of the rotating shaft 6053 and preventing the mounting seat 6054 from rotating loosely. This structure realizes the multi-functional reuse of the adjusting screw 6056, which not only undertakes the height adjustment and locking function of the lifting plate 6051, but also takes into account the angle locking function of the mounting seat 6054. It simplifies the internal structure of the clamping module 605, reduces redundant parts, and improves the module integration and ease of operation.

[0026] In this embodiment, preferably, a connecting seat 603 is fixedly installed on one side of the upper surface of the lower clamping plate 601, and fixing plates 607 are fixedly installed on both sides of the connecting seat 603. A connecting shaft 606 is rotatably installed between the two fixing plates 607, the connecting shaft 606 passes through the upper clamping plate 602, and the connecting shaft 606 is fixedly connected to the upper clamping plate 602; the fixing plates 607 are fixedly connected to the connecting seat 603 by connecting bolts 608, and multiple connecting holes 6031 are opened on both sides of the connecting seat 603, the connecting bolts 608 are adapted to the connecting holes 6031, and the connecting seat 603... Both sides of 03 are provided with through slots, through which the connecting shaft 606 passes and can move up and down within the through slots; the fixing plate 607 adopts a detachable assembly structure. By selecting the connecting holes 6031 of different heights on the connecting seat 603, the installation elevation of the fixing plate 607 can be flexibly adjusted, thereby adjusting the vertical position of the connecting shaft 606 and the upper clamping plate 602, and precisely controlling the opening and closing distance between the upper clamping plate 602 and the lower clamping plate 601. This adapts to the clamping requirements of car side panels with different thicknesses and different layer structures, further expanding the adaptability of the clamp and meeting diverse clamping conditions.

[0027] In this embodiment, preferably, the driving component includes a driving disk 609 and a hydraulic cylinder 611. The driving disk 609 is fixedly installed at the end of the connecting shaft 606. A rotating seat 610 is rotatably installed on the side wall of the lower clamping plate 601. The hydraulic cylinder 611 is fixedly installed on the rotating seat 610. The telescopic end of the hydraulic cylinder 611 is rotatably connected to the edge of the driving disk 609. Through the reciprocating telescopic motion of the telescopic end of the hydraulic cylinder 611, torque is transmitted to drive the driving disk 609 to rotate around the shaft, thereby driving the connecting shaft 606 to rotate synchronously, and finally driving the upper clamping plate 602 to open and close. The hydraulic drive method ensures stable and sufficient clamping force, and the clamping process is smooth and impact-free, avoiding pressure damage and deformation to the thin-walled components of the car side panel.

[0028] Please see Figures 2-7In this embodiment of the invention, the sliding assembly 4 includes a slide 401, a support 402, and a sleeve 403. A support 301 is fixedly disposed on the top of the mounting bracket 3. The slide 401 is sleeved on the support 301, and the slide 401 slides in cooperation with the support 301. Supports 402 are fixedly installed on both sides of the slide 401, and at least two sleeves 403 are fixedly installed on each of the two support 402. A support assembly 5 is disposed below the clamping assembly 6, and the clamping assembly 6 is connected to the support assembly 5. Component 5 is detachably connected to the sliding assembly 4; the support assembly 5 includes a support platform 501, a rotating column 503, and a guide column 502. The top end of the rotating column 503 is fixedly connected to the lower clamping plate 601, and the bottom end of the rotating column 503 passes through the support platform 501. The rotating column 503 and the support platform 501 are rotatably engaged. The top end of the rotating column 503 is fixedly connected to the lower clamping plate 601. The locking assembly 7 is used to lock the guide column 502 and the rotating column 503. Multiple [items] are fixedly installed on the lower surface of the support platform 501. Guide pillars 502, the number of which is the same as the number of sleeves 403, with multiple guide pillars 502 penetrating multiple sleeves 403 respectively, and the guide pillars 502 and sleeves 403 slidingly engaged; through the above structure, the clamping assembly 6 can be quickly disassembled and modularly replaced. During disassembly, the locking assembly 7 is released from the locking constraint on the support assembly 5 and the rotating pillar 503, and the clamping assembly 6 is pulled vertically upwards, causing the guide pillars 502 to disengage from the sleeves 403, thus completing the quick disassembly of the clamping assembly 6, which can be customized according to processing requirements. The clamping assembly 6 can be flexibly replaced with a suitable clamping component 6 according to the working conditions and workpiece specifications. When installing the clamping assembly 6, first slide the slide block 401 along the support part 301 to adjust the horizontal position, then insert the guide post 502 into the sleeve 403 to achieve initial positioning, then finely adjust the vertical height of the support platform 501 and the circumferential angle of the rotating column 503, and finally complete the integrated locking of the guide post 502, the rotating column 503 and the slide block 401 through the locking assembly 7, so as to achieve stable assembly of the clamping assembly 6, improve the efficiency of fixture changeover, and adapt to the flexible production needs of multiple vehicle models.

[0029] In this embodiment, preferably, the locking assembly 7 includes a connecting box 701, a first hydraulic cylinder 703, a second hydraulic cylinder 705, a third hydraulic cylinder 707, a second locking plate 704, a third locking plate 706, and a fourth locking plate 708. The connecting box 701 is fixedly installed on the upper surface of the slide block 401. An infusion port 702 is provided on the side wall of the connecting box 701. The first hydraulic cylinder 703, the second hydraulic cylinder 705, and the third hydraulic cylinder 707 are all connected to the connecting box 701. Multiple first hydraulic cylinders 703 are provided, and the number of first hydraulic cylinders 703 is the same as the number of guide posts 502. Multiple first hydraulic cylinders 703 are symmetrically fixedly installed on two opposite side walls of the connecting box 701. Locking plates 2 and 704 are fixedly installed on the telescopic ends of the multiple first hydraulic cylinders 703, corresponding to the guide posts 502. During locking, multiple locking plates 704 press against multiple guide posts 502 respectively. The hydraulic cylinder 705 is fixedly installed on the lower surface of the connecting box 701. A locking plate 706 is fixedly installed on the telescopic end of the hydraulic cylinder 705. When locking the slide block 401, the locking plate 706 presses against the upper surface of the support part 301. The hydraulic cylinder 707 is fixedly installed on the upper surface of the connecting box 701. A locking plate 708 is fixedly installed on the telescopic end of the hydraulic cylinder 707. When locking the rotating column 503, the locking plate 708 presses against the bottom wall of the rotating column 503. The locking plate 704 has an arc-shaped structure, thus adapting and fitting to the curved surface of the outer wall of the guide post 502. The locking plate 706 has a flat plate structure, adapting to the plane of the support part 301 for locking. The locking plate 408 is a disc structure that fits against the bottom end face of the rotating column 503. Locking plates 1 (6059), 2 (704), 3 (706), and 4 (708) are all equipped with anti-slip structures to increase the friction coefficient of the contact surface, strengthen the locking firmness, and prevent locking failure. In practical use, the inlet 702 on the connecting box 701 is connected to an external oil pump. The oil pump enables the injection and extraction of hydraulic oil from the connecting box 701. During the fixture debugging stage, the hydraulic oil in the connecting box 701 is extracted, releasing the locking constraint of the locking assembly 7 on the guide column 502, slide 401, and rotating column 503. At this time, the slide 401 can slide horizontally along the support 301, the support platform 501 can rise and fall vertically, and the rotating column 503 can move circumferentially. Rotation allows for comprehensive fine-tuning of the clamping posture. After adjustment, a temporary positioning support 501 is manually positioned to prevent displacement. Then, hydraulic oil is injected into the connecting box 701 through the infusion port 702. The hydraulic oil is simultaneously distributed to cylinders 703, 705, and 707, pushing the telescopic ends of each cylinder to extend synchronously. This causes locking plate 704 to press against guide post 502 for vertical locking, locking plate 706 to press against support part 301 for horizontal locking, and locking plate 708 to press against rotating post 503 for circumferential locking. Multi-part, multi-dimensional synchronous locking is achieved through a single locking component 7, simplifying the locking operation process, reducing the need for independent locking mechanisms, improving fixture debugging and locking efficiency, and ensuring stable positioning of each component during processing.

[0030] In this embodiment, preferably, the first hydraulic cylinder 703 includes a cylinder barrel 7031, a piston 7032, and a piston rod 7033. The first hydraulic cylinder 703 is connected to the connecting box 701. The piston 7032 is slidably disposed inside the first hydraulic cylinder 703. One end of the piston rod 7033 is fixedly connected to the piston 7032, and the other end of the piston rod 7033 is fixedly connected to the second locking plate 704. The hydraulic oil in the connecting box 701 can flow smoothly into the inner cavity of the cylinder barrel 7031. The hydraulic oil pressure pushes the piston 7032 to slide axially along the cylinder barrel 7031, and then transmits thrust through the piston rod 7033 to drive the second locking plate 704 to complete the locking action. The piston rod 7033 is the extension end of the first hydraulic cylinder 703. The structures of the second hydraulic cylinder 705 and the third hydraulic cylinder 707 are similar to those of the first hydraulic cylinder 703. They adopt a unified hydraulic drive principle to ensure the synchronization of the actions of each hydraulic cylinder and improve the operational stability of the locking assembly 7.

[0031] Working principle: Before operation, the roller edge clamp for welding automotive side panels first uses the guide rail 2 on the base 1 and the sliding component 4 on the top of the support frame to complete the rough adjustment of the horizontal two-dimensional position of the clamping component 6. The mounting frame 3 slides along the guide rail 2, and the sliding component 4 slides along the support frame; their directions of movement are perpendicular. After adjustment, the mounting frame 3 is locked with locking bolts 8 to achieve initial positioning of the clamping point. For the structural characteristics of the automotive side panel, the clamping module 605 is finely adjusted. The lifting plate 6051 is raised and lowered within the mounting groove 604 by turning the adjusting screw 6056, adapting to the height difference of the side panel curved surface to adjust the height of the support block 6055. The clamping module 605 is rotated... The mounting base 6054 switches to the appropriate support block 6055 type and adjusts the clamping angle. Then, the adjusting screw 6056 pushes the adjusting plate 6057 to drive the locking plate 6059 to lock the rotating shaft 6053, thus locking the mounting base 6054. At the same time, the position of the fixing plate 607 and the connecting shaft 606 can be adjusted through the connecting holes 6031 at different heights on the connecting base 603, and the opening and closing distance of the upper and lower clamping plates 601 can be adjusted. When the clamp holds the car side panel, the hydraulic cylinder 611 extends and retracts to drive the drive plate 609 and the connecting shaft 606 to rotate, which drives the upper clamping plate 602 to rotate, and cooperates with the lower clamping plate 601 to complete the rigid clamping and fixing of the car side panel. The slide block 401 can slide along the top support part 301 of the support frame, synchronously driving the support assembly 5 and the clamping assembly 6 to move. The guide column 502 can slide vertically along the sleeve 403, and the rotating column 503 can rotate relative to the support platform 501, realizing all-round fine adjustment of the clamping posture. After the adjustment is in place, hydraulic oil is injected into the connecting box 701 through an external oil pump. The hydraulic oil is synchronously distributed to the first cylinder 703, the second cylinder 705, and the third cylinder 707, pushing the extension end of each cylinder to extend and drive the locking plate. The second 704 clamps the guide post 502, the third 706 clamps the support part 301, and the fourth 708 clamps the rotating post 503, achieving multi-dimensional synchronous locking of the guide post 502, slide 401, and rotating post 503, ensuring the overall positioning of the fixture is stable. If the clamping component 6 needs to be replaced, simply extract the hydraulic oil from the connecting box 701 to release the locking constraint, and pull the clamping component 6 upward to disengage the guide post 502 from the sleeve 403 to complete the disassembly and replacement, adapting to the clamping and processing needs of different working conditions.
