Description

Technical Field

[0001] The utility model relates to the technical field of flange processing, in particular to a turning device used in a flange production line. Background Art

[0002] Flanges, also known as flanged discs or flanges, are components that connect shafts and are used to connect pipe ends. Flanges are also used on equipment inlets and outlets, connecting two pieces of equipment, such as reducer flanges. Flanges are typically used in pairs. Threaded flanges are suitable for low-pressure pipes, while welded flanges are used for pressures above four kilograms. During the flange manufacturing process, the inner bore of the flange must be deburred. This requires deburring the inner surface of both flange surfaces, and the flange must be flipped over.

[0003] Publication number CN219030874U discloses a flange flipping device suitable for flange production lines. The device comprises a conveyor frame with conveyor rollers mounted on both front and rear sides. A fixed platform is mounted in the middle of the conveyor frame. A chute is defined within the fixed platform, within which a slider is positioned. A hydraulic rod is mounted at one end of the slider. A toothed plate is mounted on the upper side of the slider. Fixing ears are located on either side of the toothed plate, with a special-shaped gear positioned between the two fixing ears. When the conveyor rollers transport the flange between two clamping plates, the hydraulic rod retracts the toothed plate. This retraction drives the special-shaped gear, which rotates around the fixing ear and passes through a fixed shaft. This rotation of the special-shaped gear then causes the clamping plates to flip, thereby flipping the flange.

[0004] However, the device can only flip a single flange at a time, and the flipping efficiency is low. At the same time, during the flipping process, there is no fixing device to fix the flange, which may cause the flange to roll off or deviate from the transmission route, easily causing damage to the flange and poor transmission. Therefore, it is necessary to design a flipping device for a flange production line that can improve the flange flipping efficiency. Utility Model Content

[0022] The following is a non-limiting detailed description of the technical solution of the present invention in conjunction with preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0023] See also Figure 1-3 The utility model provides a technical solution: a flip device for a flange production line, comprising an input component 1, a flip component 2 and an output component 3, wherein the flip component 2 is located between the input component 1 and the output component 3.

[0024] The input component 1 includes a conveyor belt 4, and two sets of rotatable rollers 5 are set on one side of the output end of the conveyor belt 4. The two sets of rotating rollers 5 are symmetrically arranged with respect to the center line of the width direction of the conveyor belt 4 as a reference, and a cavity 6 is formed between the two sets of rotating rollers 5.

[0025] The outgoing component 3 includes a conveyor belt 27, and two sets of rotatable rollers 28 are provided on one side of the input end of the conveyor belt 27. The two sets of rotating rollers 28 are symmetrically arranged with respect to the center line of the width direction of the conveyor belt 27 as a reference, and a cavity 29 is formed between the two sets of rotating rollers 28.

[0026] The flip assembly 2 is located between the rotating roller 1 5 and the rotating roller 2 8, and includes a rotatable rotating shaft 10. Connecting plates 11 are provided at both ends of the rotating shaft 10 along the axial direction. The rotating shaft 10 is movably connected to the connecting plates 11. The connecting plates 11 are fixedly connected to the frames of the conveyor belt 1 4 and the conveyor belt 2 7 at both ends along the length direction.

[0027] A rotating motor 12 is fixedly connected to one side of the connecting plates 11 away from the rotating shaft 10 , and an output end of the rotating motor 12 passes through the connecting plate 11 and is fixedly connected to the rotating shaft 10 .

[0028] Several groups of fixing components 13 are fixedly connected to the rotating shaft 10. The several groups of fixing components 13 are evenly distributed on the circumference with the axis of the rotating shaft 10 as the center. Each group of fixing components 13 includes two supporting plates 14 parallel to each other. The two supporting plates 14 are fixedly connected to a fixing block 15 on the side close to the rotating shaft 10. The fixing block 15 is fixedly connected to the rotating shaft 10. A groove 16 is formed after the two support plates 14 and the fixing block 15 are connected. The groove 16 is used to accommodate the flange and is transported and moved by rotating the rotating shaft 10.

[0029] On one side of the two support plates 14 facing away from each other, a support assembly, a pressing assembly and a limiting assembly are symmetrically arranged in sequence along the length direction of the support plates 14 , and the support assembly is close to the side of the fixing block 15 .

[0030] The support assembly includes two hydraulic telescopic cylinders 17. The two hydraulic telescopic cylinders 17 on the same support plate 14 are arranged on the side of the support plate 14 close to the fixed block 15. The two hydraulic telescopic cylinders 17 on the same support plate 14 are respectively arranged at both ends of the support plate 14 along the width direction. The telescopic direction of the output end of the hydraulic telescopic cylinder 17 is consistent with the length direction of the support plate 14.

[0031] The output ends of the two hydraulic telescopic cylinders 17 are fixedly connected to a connecting block 18, which is "L"-shaped. The two connecting blocks 18 at the same position on the two support plates 14 are fixedly connected to the opposite sides of a limit rod 19. The limit rod 19 is used to ensure that the flange does not directly contact the bottom of the groove 16, thereby supporting the flange.

[0032] According to the diameter of the flange, the output end of the hydraulic telescopic cylinder 17 is controlled to be telescopic, thereby adjusting the distance between the limit rod 19 and the inner wall of the bottom of the groove 16.

[0033] The limiting assembly includes two hydraulic telescopic cylinders 20. The two hydraulic telescopic cylinders 20 on the same support plate 14 are arranged on the side of the support plate 14 away from the fixed block 15. The two hydraulic telescopic cylinders 20 on the same support plate 14 are respectively arranged at both ends of the support plate 14 along the width direction. The telescopic direction of the output end of the hydraulic telescopic cylinder 20 is consistent with the length direction of the support plate 14.

[0034] The output ends of the two hydraulic telescopic cylinders 20 are fixedly connected to the sliders 21, and the support plate 14 is provided with a sliding groove 22 corresponding to the sliders 21. The sliders 21 slide in the sliding groove 22, and the side of the sliders 21 away from the support plate 14 is fixedly connected to the hydraulic telescopic cylinder 3 23.

[0035] The hydraulic telescopic cylinder three 23 is arranged vertically, and the output end of the hydraulic telescopic cylinder three 23 is fixedly connected to the connecting block two 24. The connecting block two 24 is "L"-shaped, and the two connecting blocks two 24 at the same position on the two support plates 14 are fixedly connected to the opposite sides with a fixing rod 25.

[0036] The output end of the hydraulic telescopic cylinder 3 23 is controlled to retract, so that the fixing rods 25 on the two support plates 14 are in contact with each other. According to the diameter of the flange, the output end of the hydraulic telescopic cylinder 20 is controlled to extend and retract, thereby adjusting the distance between the fixing rod 25 and the inner wall of the bottom of the groove 16. In this way, the flange is fixed in the horizontal direction in cooperation with the limit rod 19 to prevent the flange from shaking during rotation.

[0037] The clamping assembly includes several hydraulic telescopic cylinders 26, which are located between hydraulic telescopic cylinder 1 17 and hydraulic telescopic cylinder 2 20.

[0038] The hydraulic telescopic cylinders 26 on the same support plate 14 are symmetrically arranged at both ends of the support plate 14 along the width direction, and are arranged in a linear array along the length direction of the support plate 14.

[0039] The hydraulic telescopic cylinder four 26 is arranged vertically, and the output end of the hydraulic telescopic cylinder four 26 is fixedly connected to the connecting block three 27, and the connecting block three 27 is "L"-shaped. The two connecting blocks three 27 at the same position on the two support plates 14 are fixedly connected to the opposite sides with a pressure plate 28.

[0040] When the flange enters the groove 16, the flange is limited and fixed in the horizontal direction by the limit rod 19 and the fixing rod 25, and then the output end of the hydraulic telescopic cylinder 26 is controlled to retract, so that the pressure plate 28 presses the flange and limits and fixes the flange in the vertical direction, thereby fully limiting and fixing the flange.

[0041] In this embodiment, the flange is transferred from the conveyor belt 4 to the rotating roller 5. At this time, one of the fixed components 13 is horizontally located in the cavity 6. Under the limiting action of the connecting plate 11, the flange moves into the groove 16. According to the diameter of the flange, the output end of the hydraulic telescopic cylinder 17 is controlled to extend, so that the limiting rod 19 supports the flange to prevent the flange from contacting the bottom of the groove 16.

[0042] Then, the output end of the hydraulic telescopic cylinder three 23 is controlled to retract, so that the corresponding fixed rods 25 on the two support plates 14 are docked and contacted, and at the same time, the output end of the hydraulic telescopic cylinder two 20 is controlled to retract, so that the fixed rod 25 moves and cooperates with the limit rod 19 to limit and fix the flange in the horizontal direction. Then, the output end of the hydraulic telescopic cylinder four 26 is controlled to retract, so that the pressure plate 28 presses the flange and limits and fixes the flange in the vertical direction to prevent the flange from shaking during the subsequent rotation and movement.

[0043] After the flange is fixed, the rotating motor 12 is started, and the rotating motor 12 drives the rotating shaft 10 to rotate, so that the flange after being fixed is rotated to the side of the outgoing component 3 under the fixation of the fixing component 13 and is horizontally located in the cavity 2 9.

[0044] Then, the output end of the hydraulic telescopic cylinder 4 26 is controlled to extend and reset, and the pressure plate 28 does not press the flange. The output end of the hydraulic telescopic cylinder 3 23 is controlled to extend, and the corresponding fixing rods 25 on the two support plates 14 are separated. The flange is not limited, and the flange is driven by the rotating roller 2 8 to enter the conveyor belt 2 7 and move out, thereby completing the flipping of the flange on the production line.
