Description

Technical Field

[0001] This invention relates to the field of sweeper housing flipping technology, specifically to a sweeper housing flipping device and method for processing sweeper housings. Background Technology

[0002] As the core structural component of a sweeper, the sweeper housing is often an integrally designed irregular curved surface. It must meet high processing requirements, including waterproofing, drop resistance, and assembly precision. During the entire processing cycle, including milling, grinding, drilling, painting, and assembly, the housing needs to be rotated and positioned from multiple angles and directions. This is a crucial step in ensuring both processing quality and efficiency. Currently, the rotation of sweeper housings during processing mainly relies on manual rotation or simple tooling. Some small workshops even manually rotate and position the housing by hand. However, existing rotation devices have the following drawbacks in practical use: For small-sized or thin-walled housings, if the clamping spring damping is fixed and too large, the spring clamping force will exceed the tolerance range of the housing structure, which can easily cause the side wall of the housing to be squeezed and deformed, the surface to be indented, and even damage to precision structures such as buckles and mounting holes, directly reducing the yield rate of finished products. For large-sized or thick-walled housings, if the fixed damping is too small, the spring clamping force will be insufficient and unable to provide a stable clamping preload. The housing is prone to slight displacement and shaking during flipping and processing, which not only affects the processing accuracy of milling, drilling, and painting processes, but may also cause the housing to flip and slide due to loose clamping, posing a safety hazard. Meanwhile, the fixed flipping speed, lacking adaptive speed adjustment, poses a significant challenge for large housings. The housing's inherent inertia generates substantial centrifugal force and impact loads during flipping, further exacerbating clamping loosening and housing misalignment. Additionally, it causes instantaneous impacts to the flipping shaft, drive gears, and other transmission components, leading to wear and deformation over time, reducing overall equipment stability. Furthermore, high-speed flipping increases the risk of large housings falling, posing a significant safety hazard. For small housings, the fixed speed and lack of speed-up design fail to match the characteristics of low loads, resulting in prolonged flipping times. Frequent flipping significantly increases auxiliary processing time, slowing down the entire production line and hindering batch processing needs, leading to processing efficiency far below design expectations. Moreover, the fixed curvature of the curved clamping plate prevents adjustment based on housing size, hindering full-fit clamping of irregularly shaped curved surfaces and directly impacting positioning stability.

[0003] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

The end of the rotating shaft is fixedly connected to the side of the arc-shaped clamping plate by bolts. A rotating speed adjustment assembly is provided on the outside of the rotating shaft, and the rotating speed adjustment assembly is linked to the damping adjustment assembly. A rack is fixedly connected inside the frame below the bidirectional threaded rod. A first telescopic rod is bearing-connected to the side of each of the two vertical ends of the base. The first telescopic rod is drive-connected to the damping adjustment assembly, and a drive gear is sleeved and fixed on the outer side of the upper end of each of the two first telescopic rods. The drive gear is meshed with the rack.

[0006] Preferably, the threads on the outer sides of the two ends of the bidirectional threaded rod have opposite directions, and the left end of the bidirectional threaded rod extends out of the outer surface of the frame. Both movable plates are threadedly connected to the outer sides of the two ends of the bidirectional threaded rod, and the outer sides of the upper ends of the two movable plates are slidably connected to the inner wall of the frame.

[0007] Preferably, the upper surfaces of both support seats are bolted with second telescopic rods, and lifting plates are sleeved on the outer sides of the first and second telescopic rods. The front of the lifting plates is equidistantly connected with speed-regulating rollers via shafts.

[0008] Preferably, the outer side of the upper end of the first telescopic rod is provided with threads, and the first telescopic rod and the lifting plate are connected by threads, while the lifting plate and the second telescopic rod are connected by sliding.

[0009] Preferably, the damping adjustment assembly includes a fixed cylinder, which is fixed inside the support base, and a movable cylinder is slidably connected through one end of the fixed cylinder. A lead screw is rotatably connected inside the fixed cylinder, and an adjusting plate is threadedly connected to the outside of the lead screw. A buffer spring is installed between the side of the adjusting plate and the inner wall of the movable cylinder. The end of the lead screw is connected to the bottom end of the first telescopic rod through a bevel gear set.

[0010] Preferably, the flipping speed adjustment assembly includes a connecting sleeve, which is fixedly installed on the side of the adjustment plate by bolts, and a linkage slip ring is fixedly connected to the outer side of the right end of the connecting sleeve by four connecting rods. The side of the linkage slip ring is provided with a rolling groove. A conical adjustment platform is sleeved and fixed on the outer side of the flipping shaft, and a ball bearing is embedded at an equal angle at the left end of the conical adjustment platform.

[0011] Preferably, the connecting sleeve and the flip shaft are both hollow inside, and the right end of the connecting sleeve extends into the interior of the flip shaft. The ball and the groove on the linkage slip ring are in a rolling connection. The conical adjustment platform is designed with a conical shape that is narrower on the left and wider on the right.

[0012] Preferably, the arc-shaped clamping plate is provided with arc-shaped extension clamping plates on both the left and right sides, a turntable is sleeved and fixed on the outer side of the flipping shaft, guide wheels are symmetrically arranged on the side of the turntable, and a pull rope is wound and connected to the outer side of the guide wheel.

[0013] Preferably, both of the arc-shaped extension clamps are hinged to both sides of the arc-shaped clamping plate, and a torsion spring is installed at the connection position between the shaft end of the arc-shaped extension clamp and the arc-shaped clamping plate. The two ends of the pull rope are fixedly connected to the opposite surfaces of the turntable and the arc-shaped extension clamp, respectively.

[0014] The present invention also provides a flipping method for processing the casing of a sweeper, applicable to the aforementioned flipping device for processing the casing of a sweeper, the method comprising the following steps: S1. Lifting and positioning: The cylinder drives the base and the arc-shaped clamping plate to lift and lower, so that the arc-shaped clamping plate can be accurately moved to the clamping position of the sweeper housing, adapting to the needs of housings of different heights. S2. Adaptive clamping: The motor drives the bidirectional threaded rod to rotate, which drives the two sets of movable plates and arc-shaped clamping plates to move relative to or towards each other. By adjusting the clamping distance, it can achieve firm clamping and fixing of housings of different sizes. S3. Damping adaptive adjustment: When the arc-shaped clamping plate moves, the drive gear moves synchronously along the rack and drives the first telescopic rod to rotate, which drives the lead screw to rotate through the bevel gear set; the adjustment plate moves synchronously with the arc-shaped clamping plate, and stretches or compresses the buffer spring according to the size of the machine housing to complete the damping adjustment, ensuring clamping stability and avoiding damage to the machine housing; S4. Adaptive adjustment of tilting speed: When the adjustment plate moves, it synchronously drives the connecting sleeve, the linkage slip ring and the conical adjustment table to move; relying on the conical structure of the conical adjustment table and the threaded transmission of the first telescopic rod, it drives the lifting plate and the speed regulating roller to move up and down. Through the abutment linkage between the speed regulating roller and the conical adjustment table, the tilting speed is adaptively adjusted according to the shell size. S5. Clamping arc adaptive adjustment: When the adjustment plate moves to the right, the pull rope pulls the arc-shaped extension clamping plate outward; when the adjustment plate returns to the left, the pull rope is released, and the arc-shaped extension clamping plate retracts inward under the action of the torsion spring, so as to achieve a full fit between the clamping arc and the curved surface of the machine casing. S6. Tilting Processing: After completing the adaptive adjustment of clamping, damping, speed and arc, the two cylinders drive the base and the fixed sweeper housing to move upward, so that the conical adjustment table on the tilting shaft abuts against multiple speed-regulating rollers. With the help of contact friction, the tilting shaft rotates synchronously, causing the housing to rotate smoothly to the target processing angle at a preset speed.

[0015] This invention achieves adaptive adjustment and precise buffer control for the clamping of sweeper housings, effectively improving clamping stability and processing yield. Precise lifting and positioning are achieved by a cylinder-driven base and clamping plate, while a motor-driven bidirectional threaded rod moves the clamping plate relative to or towards each other. This flexibly adapts to the clamping needs of sweeper housings of different sizes, eliminating the need for manual adjustment of the clamping structure and demonstrating strong adaptability. Simultaneously, during the movement of the clamping plate, the meshing linkage of the drive gear and rack drives the lead screw to rotate. The adjusting plate moves synchronously with the clamping plate and adaptively stretches or compresses the buffer spring, achieving dynamic damping adjustment. This avoids damage to small, thin-walled housings due to excessive damping, while ensuring sufficient clamping preload for large, thick-walled housings, preventing displacement and wobbling during the flipping process. This fundamentally reduces the risk of housing damage and significantly improves processing yield.

[0016] This invention achieves adaptive and precise control of the sweeper's casing rotation speed, further optimizing processing adaptability. When the adjustment plate moves to match the casing size, it synchronously links the connecting sleeve, the linkage slip ring, and the conical adjustment platform. Relying on the left-narrow-right-wide structural design of the conical adjustment platform, combined with the threaded transmission of the first telescopic rod and the meshing of the drive gear and rack, it can drive the lifting plate and speed-regulating roller to move up and down. Through the adaptive contact between the conical adjustment platform and the speed-regulating roller, the rotation speed is automatically matched and precisely adjusted to match the casing size, adapting to the rotation processing needs of casings of different specifications and improving processing coordination and stability.

[0017] This invention enables the automatic unfolding and retraction of the arc-shaped extension clamping plate, improving clamping accuracy and automation while reducing labor costs. When the adjusting plate moves the connecting sleeve and the linkage slip ring, the arc-shaped extension clamping plate automatically unfolds and retracts through the combination of the pull rope and the torsion spring. The effective clamping arc and range of the clamping plate can be adaptively adjusted without manual intervention, allowing the arc-shaped clamping plate to achieve full fit clamping with the irregular curved surfaces of machine housings of different sizes. This effectively avoids damage to the machine housing and clamping warping caused by local stress concentration, significantly improving positioning and clamping accuracy. At the same time, the automated clamping adaptation structure is suitable for batch processing of machine housings of multiple specifications, reducing manual operation steps, lowering labor costs, and improving processing efficiency and versatility.

[0027] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0028] Please see Figures 1-8 This invention provides a technical solution: a flipping device and method for processing the casing of a sweeper, comprising a frame 1, with movable plates 2 symmetrically arranged below the frame 1, and bases 3 slidably connected to the opposite surfaces of the two movable plates 2. Support seats 4 are fixed to the upper surfaces of the horizontal ends of the two bases 3, and arc-shaped clamping plates 5 are connected to the opposite surfaces of the two bases 3. It also includes a bidirectional threaded rod 6, which is bearing-connected inside the frame 1. A motor is installed on the left side of the frame 1, and the output end of the motor is fixedly connected to the left end of the bidirectional threaded rod 6. The threads on the outer sides of the two ends of the bidirectional threaded rod 6 have opposite directions, and the left end of the bidirectional threaded rod 6 extends beyond the outer surface of the frame 1. The two movable plates 2 are threadedly connected to the outer sides of the two ends of the bidirectional threaded rod 6, and the outer sides of the upper ends of the two movable plates 2 are slidably connected to the inner wall of the frame 1. Cylinders 7 are installed above the opposite surfaces of the two movable plates 2, and the telescopic ends of the cylinders 7 are connected to the vertical ends of the bases 3 by screws. The base 3 is fixedly connected to the upper surface of the horizontal end of the base 3 with fixed plates 8. The two fixed plates 8 are connected through the interior of the two fixed plates 8 with a rotating shaft 9. The end of the rotating shaft 9 is fixedly connected to the side of the arc-shaped clamping plate 5 with bolts. The frame 1 is fixedly connected to the rack 1 below the bidirectional threaded rod 6. The two vertical ends of the base 3 are connected to the first telescopic rod 13 with bearings. The upper outer sides of the two first telescopic rods 13 are fitted with drive gears 10. The upper surfaces of the two support seats 4 are bolted to the second telescopic rod 20. The outer sides of the first telescopic rod 13 and the second telescopic rod 20 are fitted with lifting plates 12. The front of the lifting plates 12 is rotatably connected to speed-regulating rollers 19 at equal intervals through shafts. The upper outer side of the first telescopic rod 13 is threaded. The first telescopic rod 13 and the lifting plate 12 are threadedly connected. The lifting plate 12 and the second telescopic rod 20 are slidably connected. The drive gear 10 and the rack 11 are meshed.

[0029] In one embodiment of the present invention, the cylinder 7 first drives the base 3 and the arc-shaped clamping plate 5 to complete the lifting action, so that the arc-shaped clamping plate 5 is precisely moved to the clamping position of the sweeper housing; then the motor drives the bidirectional threaded rod 6 to rotate, which drives the two sets of movable plates 2 to move relative to each other or towards each other. The movable plates 2 move synchronously with the arc-shaped clamping plate 5. By adjusting the distance between the two sets of arc-shaped clamping plates 5, adaptive clamping and fixing of sweeper housings of different sizes can be achieved.

[0030] The support base 4 is equipped with a damping adjustment assembly, which includes a fixed cylinder 1401. The fixed cylinder 1401 is fixed inside the support base 4, and a movable cylinder 1402 is slidably connected through one end of the fixed cylinder 1401. A lead screw 1406 is rotatably connected inside the fixed cylinder 1401, and an adjusting plate 1404 is threadedly connected to the outside of the lead screw 1406. A buffer spring 1403 is installed between the side of the adjusting plate 1404 and the inner wall of the movable cylinder 1402. The end of the lead screw 1406 is connected to the bottom end of the first telescopic rod 13 through a bevel gear set 1405.

[0031] In one embodiment of the present invention, during the movement of the arc-shaped clamping plate 5, the drive gear 10 moves horizontally synchronously along the rack 11 and drives the first telescopic rod 13 to rotate. The first telescopic rod 13 drives the lead screw 1406 to rotate through the transmission action of the bevel gear set 1405. At the same time, the adjusting plate 1404 moves synchronously with the movement of the arc-shaped clamping plate 5, and adapts the buffer spring 1403 to stretch or compress according to the actual size of the clamped housing, thereby completing the damping adjustment of the buffer spring 1403. This avoids small-sized / thin-walled housings from being squeezed and damaged due to excessive damping, while ensuring that large-sized / thick-walled housings obtain sufficient clamping preload, preventing offset and shaking problems during flipping processing, and greatly improving clamping stability and housing processing yield.

[0032] A tilting speed adjustment assembly is provided on the outer side of the tilting shaft 9, and the tilting speed adjustment assembly is linked to the damping adjustment assembly. The tilting speed adjustment assembly includes a connecting sleeve 1501, which is fixedly installed on the side of the adjusting plate 1404 by bolts. A linkage slip ring 1503 is fixedly connected to the outer side of the right end of the connecting sleeve 1501 by four connecting rods. The side of the linkage slip ring 1503 has a rolling groove. A conical adjusting platform 1502 is sleeved and fixed on the outer side of the tilting shaft 9, and a ball bearing 1504 is rolled and connected at an equal angle to the left end of the conical adjusting platform 1502. The interiors of the connecting sleeve 1501 and the tilting shaft 9 are hollow, and the right end of the connecting sleeve 1501 extends into the interior of the tilting shaft 9. The roller groove on the linkage slip ring 1503 is rolled. The conical adjustment table 1502 is designed with a conical shape that is narrow on the left and wide on the right. Arc-shaped extension clamping plates 16 are provided on both the left and right sides of the arc-shaped clamping plate 5. A turntable 18 is fixedly sleeved on the outside of the flipping shaft 9. Guide wheels are symmetrically arranged on the side of the turntable 18, and a pull rope 17 is wound around the outside of the guide wheels. The two arc-shaped extension clamping plates 16 are hinged on both sides of the arc-shaped clamping plate 5. A torsion spring is installed at the connection position between the shaft end of the arc-shaped extension clamping plate 16 and the arc-shaped clamping plate 5. The two ends of the pull rope 17 are fixedly connected to the opposite surfaces of the turntable 18 and the arc-shaped extension clamping plate 16, respectively.

[0033] In one embodiment of the present invention, when the adjusting plate 1404 adapts to the movement of the sweeper housing of different sizes, it synchronously drives the connecting sleeve 1501, the linkage slip ring 1503, and the conical adjusting platform 1502 to move in linkage. Based on the conical structure design of the conical adjusting platform 1502 (narrower on the left and wider on the right), combined with the threaded transmission on the outer side of the first telescopic rod 13, when the first telescopic rod 13 rotates due to the meshing action of the drive gear 10 and the rack 11, it can drive the lifting plate 12 and multiple speed-regulating rollers 19 on the plate to achieve vertical displacement. Through the adaptive abutment linkage between the conical adjusting platform 1502 and the speed-regulating rollers 19, the flipping speed can be adaptively and precisely adjusted according to the size of the sweeper housing. Furthermore, by utilizing the groove on the linkage slip ring 1503 and the multiple balls 1504 on the conical adjusting platform 1502, it is possible to prevent the linkage slip ring 1503 from rotating along with the conical adjusting platform 1502, while not hindering the linkage slip ring 1503 from pushing the conical adjusting platform 1502 forward. The device moves along the housing, and when the adjusting plate 1404 moves the connecting sleeve 1501 and the linkage slip ring 1503 to the right, the pulling rope 17 pulls the arc-shaped extension clamping plate 16 to rotate and unfold outward. When the adjusting plate 1404 moves the connecting sleeve 1501 and the linkage slip ring 1503 to the left to reset, the pulling force of the pulling rope 17 is released, and the arc-shaped extension clamping plate 16 rotates and retracts inward under the elastic reset force of the torsion spring. Thus, the arc-shaped extension clamping plate 16 is automatically extended and retracted through mechanical linkage. The effective clamping arc and clamping range of the arc-shaped clamping plate 5 can be adaptively adjusted according to the size of the housing, so that the arc-shaped clamping plate 5 can fully fit and clamp the irregular curved surface of the housing of different sizes, avoiding housing damage and clamping warping caused by local stress concentration, and greatly improving the positioning and clamping accuracy. At the same time, there is no need for manual adjustment of the clamping plate structure, which has high adaptability and automation, effectively reducing the cost of manual operation and adapting to the batch processing needs of housings of multiple specifications.

[0034] A method for flipping the casing of a sweeper includes the following steps: S1. Lifting and positioning: Cylinder 7 drives the base 3 and the arc-shaped clamping plate 5 to lift and lower, so that the arc-shaped clamping plate 5 can be accurately moved to the clamping position of the sweeper housing to adapt to the housing requirements of different heights. S2. Adaptive clamping: The motor drives the bidirectional threaded rod 6 to rotate, which drives the two sets of movable plates 2 and the arc-shaped clamping plate 5 to move relative to or towards each other. By adjusting the clamping distance, it can achieve firm clamping and fixing of housings of different sizes. S3. Damping adaptive adjustment: When the arc-shaped clamping plate 5 moves, the drive gear 10 moves synchronously along the rack 11 and drives the first telescopic rod 13 to rotate, which drives the lead screw 1406 to rotate via the bevel gear set 1405; the adjustment plate 1404 moves synchronously with the arc-shaped clamping plate 5, and stretches or compresses the buffer spring 1403 according to the size of the machine housing to complete the damping adjustment, ensuring clamping stability and avoiding damage to the machine housing; S4. Adaptive adjustment of flipping speed: When the adjustment plate 1404 moves, it synchronously drives the connecting sleeve 1501, the linkage slip ring 1503 and the conical adjustment table 1502 to move; relying on the conical structure of the conical adjustment table 1502 and the threaded transmission of the first telescopic rod 13, it drives the lifting plate 12 and the speed regulating roller 19 to move up and down. Through the linkage between the two, the flipping speed is adaptively adjusted according to the size of the shell. S5. Clamping arc adaptive adjustment: When the adjustment plate 1404 moves to the right, the pull rope 17 pulls the arc-shaped extension clamping plate 16 to unfold outward; when the adjustment plate 1404 returns to the left, the pull rope 17 releases its tension, and the arc-shaped extension clamping plate 16 retracts inward under the action of the torsion spring, so as to achieve a full fit between the clamping arc and the curved surface of the machine casing. S6. Flipping Processing: After completing the adaptive adjustment of clamping, damping, speed and arc, the two cylinders 7 drive the base 3 and the fixed sweeper housing to move upward, so that the conical adjustment table 1502 on the flipping shaft 9 abuts against multiple speed-regulating rollers 19. With the help of contact friction, the flipping shaft 9 rotates synchronously, and the housing is flipped smoothly to the target processing angle at a preset speed.

A turntable (18) is fixedly sleeved on the outside of the flipping shaft (9). Guide wheels are symmetrically arranged on the side of the turntable (18), and a pull rope (17) is wound around the outside of the guide wheel.

9. A flipping device for processing the casing of a sweeper according to claim 8, characterized in that: Both of the arc-shaped extension clamps (16) are hinged to the two sides of the arc-shaped clamping plate (5), and a torsion spring is installed at the connection position between the shaft end of the arc-shaped extension clamp (16) and the arc-shaped clamping plate (5). The two ends of the pull rope (17) are fixedly connected to the turntable (18) and the opposite surfaces of the arc-shaped extension clamp (16), respectively.

10. A method for flipping over the casing of a sweeper, characterized in that: A flipping device for processing the casing of a sweeper, applicable to any one of claims 1-9, comprises the following steps: S1, Lifting and Alignment: The cylinder (7) drives the base (3) and the arc-shaped clamping plate (5) to lift and lower, so that the arc-shaped clamping plate (5) can be accurately moved to the clamping position of the sweeper housing to adapt to the housing requirements of different heights. S2, Adaptive clamping: The motor drives the bidirectional threaded rod (6) to rotate, which drives the two sets of movable plates (2) and the arc-shaped clamping plate (5) to move relative to each other or towards each other. By adjusting the clamping distance, the machine housing of different sizes can be firmly clamped and fixed. S3, Damping Adaptive Adjustment: When the arc-shaped clamping plate (5) moves, the drive gear (10) moves synchronously along the rack (11) and drives the first telescopic rod (13) to rotate, which drives the lead screw (1406) to rotate via the bevel gear set (1405); the adjustment plate (1404) moves synchronously with the arc-shaped clamping plate (5), and stretches or compresses the buffer spring (1403) according to the size of the machine housing to complete the damping adjustment, ensuring clamping stability and avoiding damage to the machine housing; S4. Adaptive adjustment of flipping speed: When the adjustment plate (1404) moves, it synchronously drives the connecting sleeve (1501), the linkage slip ring (1503) and the conical adjustment table (1502) to move; relying on the conical structure of the conical adjustment table (1502) and the threaded transmission of the first telescopic rod (13), it drives the lifting plate (12) and the speed regulating roller (19) to move up and down. Through the abutment linkage between the speed regulating roller (19) and the conical adjustment table (1502), the flipping speed is adaptively adjusted according to the shell size. S5. Clamping arc adaptive adjustment: When the adjustment plate (1404) moves to the right, the pull rope (17) pulls the arc extension clamp (16) outward; when the adjustment plate (1404) returns to the left, the pull rope (17) releases its tension, and the arc extension clamp (16) retracts inward under the action of the torsion spring, so as to achieve a full fit between the clamping arc and the curved surface of the machine shell. S6. Flipping process: After completing the adaptive adjustment of clamping, damping, speed and arc, the two cylinders (7) drive the base (3) and the fixed sweeper housing to move upward, so that the conical adjustment table (1502) on the flipping shaft (9) abuts against multiple speed-adjusting rollers (19), and drives the flipping shaft (9) to rotate synchronously by means of contact friction, so that the housing can be flipped smoothly to the target processing angle at a preset speed.
