Description

Technical Field

[0001] This utility model relates to the technical field of pipe fitting assembly equipment, and in particular to a pipe fitting ring device. Background Technology

[0002] In the field of pipe connections, in order to ensure sealing, it is often necessary to put sealing rings on the ends or specific locations of pipe fittings.

[0003] Currently, this process relies heavily on manual operation, where workers manually expand the rubber rings and slip them onto the pipe fittings. This traditional method is inefficient, labor-intensive, and unsuitable for large-scale production.

[0004] Secondly, the consistency of the ring fitting operation is poor. The position and tightness of the ring depend entirely on the worker's experience, which can easily lead to problems such as missing rings, misalignment, or twisting, directly affecting the sealing quality of the product. Furthermore, repeated manual operation can easily cause worker fatigue, and long-term operation may also cause damage to the worker's fingers. There is also a risk that the rubber ring may be permanently deformed or broken due to excessive stretching. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a pipe fitting ringing device to solve the technical problems of low efficiency and poor consistency in existing pipe fitting ringing methods.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A pipe fitting ringing device includes a worktable with a turntable for placing pipe fittings rotatably mounted on it. The worktable is also equipped with a mounting frame with a mounting assembly for holding rubber rings. A fixing plate is mounted on the mounting frame and above the mounting assembly. A ringing assembly for fitting the rubber rings from the mounting assembly onto the pipe fitting is rotatably mounted on the fixing plate. A driving component for rotating the ringing assembly is also provided on the mounting frame.

[0008] The present invention is further configured such that: the mounting assembly includes a fixed frame, a conveying plate, and a retaining ring cylinder; the fixed frame is fixed on the mounting frame, and a fixed block inclined downward toward the turntable is fixed on the fixed frame; the conveying plate is fixed at the end of the fixed block away from the turntable, and the conveying plate is used to convey the rubber ring to the fixed block; the retaining ring cylinder is fixed on the fixed block, and two opposing retaining ring clamps are provided on the telescopic end of the retaining ring cylinder, and the two retaining ring clamps are used to position the rubber ring on the fixed block.

[0009] The present invention is further configured such that: the ring assembly includes a mounting plate, a first cylinder, a spreading cylinder, and a second cylinder; the mounting plate is rotatably mounted on a fixed plate; a slide rail is fixedly mounted on the mounting plate; a slider is slidably mounted on the slide rail; the first cylinder is fixedly mounted on the mounting plate; the telescopic end of the first cylinder is fixedly connected to one end of the slider; the spreading cylinder is fixedly mounted on the slider; the telescopic end of the spreading cylinder is provided with a rubber ring clamp for spreading and clamping the rubber ring; the second cylinder is fixedly mounted on the slider; a sliding frame with the same sliding direction as the slider slides through the slider; the telescopic end of the second cylinder is fixedly connected to one end of the sliding frame; and the sliding frame is provided with an ejector plate for removing the rubber ring from the rubber ring clamp.

[0010] The present invention is further configured such that: the driving component includes a rotating shaft, a rotating block and a third cylinder; the rotating shaft is rotatably mounted on a fixed plate; one end of the rotating shaft is fixedly connected to a mounting plate; the rotating block is fixedly mounted on the end of the rotating shaft away from the mounting plate; a support block is fixedly mounted on the mounting bracket; the third cylinder is hinged to the support block; and the telescopic end of the third cylinder is hinged to one side of the rotating block.

[0013] Compared to the desired effects achieved by existing technologies:

[0014] Compared to existing technologies, this pipe fitting ring-fitting device achieves mechanization and automation of the rubber ring fitting process through the coordinated rotation design of the turntable and the ring-fitting assembly.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example:

[0022] Reference Figures 1-4 This application relates to a pipe fitting ringing device, including a worktable 1, on which a turntable 2 for placing pipe fittings is rotatably mounted. The pipe fittings can be continuously placed on the turntable 2 via a customized conveyor. A mounting bracket 3 is provided on the worktable 1. Figure 2 As shown, the mounting frame 3 is equipped with a mounting assembly for holding rubber rings. The mounting assembly includes a fixed frame 5, a conveying plate 6, and a retaining ring cylinder 7. The fixed frame 5 is fixed to the mounting frame 3, and a fixed block 8 inclined downwards towards the turntable 2 is fixed on the fixed frame 5. The conveying plate 6 is fixed to the end of the fixed block 8 away from the turntable 2. The other end of the conveying plate 6 is connected to a rubber ring conveying device. The conveying plate 6 is used to convey rubber rings to the fixed block 8. The retaining ring cylinder 7 is fixed to the fixed block 8. Two opposing retaining ring grippers 9 are provided on the telescopic end of the retaining ring cylinder 7. The two retaining ring grippers 9 are used to position the rubber rings on the fixed block 8. The aforementioned retaining ring cylinder 7 and retaining ring grippers 9 are clamping cylinder mechanisms in the prior art, and their specific principles will not be elaborated in detail here. A sensor 23 for detecting rubber rings is fixed to the end of the fixed block 8 facing the turntable 2. This arrangement allows the sensor 23 to detect whether there is a rubber ring on the fixed block 8. The sensor 23 can be a pressure sensor.

[0023] like Figure 2 and Figure 4As shown, a fixing plate 4 is provided on the mounting bracket 3 and above the fixing block 8. A collar assembly for fitting the rubber ring inside the mounting assembly onto the pipe fitting is rotatably mounted on the fixing plate 4. The collar assembly includes a mounting plate 10, a first cylinder 11, a spreading cylinder 12, and a second cylinder 13. The mounting plate 10 is rotatably mounted on the fixing plate 4. A slide rail 14 is fixedly mounted on the mounting plate 10, and a slider 15 is slidably mounted on the slide rail 14. The first cylinder 11 is fixedly mounted on the mounting plate 10, and the telescopic end of the first cylinder 11 is fixedly connected to one end of the slider 15. The spreading cylinder 12 is fixedly mounted on the first cylinder 12. A second cylinder 13 is fixedly mounted on the slider 15. A sliding frame 17, which slides along the slider 15 in the same direction as the slider 15, is fixedly connected to one end of the sliding frame 17. The sliding frame 17 has an ejector plate 18 for removing the rubber ring from the rubber ring clamp 16. The ejector plate 18 is configured to abut against one side of the rubber ring on the rubber ring clamp 16 after the rubber ring clamp 16 is opened. The aforementioned pneumatic opening mechanism, consisting of the extension and retraction of the opening cylinder 12 to control the opening and closing of the rubber ring clamp 16, is a common technical structure in the art.

[0024] like Figure 3 As shown, the mounting frame 3 is equipped with a driving component for rotating the ring assembly. The driving component includes a rotating shaft 19, a rotating block 20, and a third cylinder 21. The rotating shaft 19 is rotatably mounted on the fixed plate 4, and one end of the rotating shaft 19 is fixedly connected to the mounting plate 10. The rotating block 20 is fixedly mounted on the end of the rotating shaft 19 away from the mounting plate 10. A support block 22 is fixedly mounted on the mounting frame 3. The third cylinder 21 is hinged to the support block 22 via a shaft fixedly sleeved on it and rotatably mounted on the support block 22. The telescopic end of the third cylinder 21 is hinged to one side of the rotating block 20. The telescopic end of the third cylinder 21 can be directly rotatably connected to one side of the rotating block 20 via a bearing.

[0025] like Figure 2 As shown, the fixed plate 4 is provided with a limiting block 24, and two limiting bolts 25 are rotatably inserted on the limiting block 24 to prevent the mounting plate 10 from rotating excessively. The limiting block 24 is provided with a hydraulic buffer 26 that abuts against the mounting plate 10 when the rubber ring clamp 16 faces the mounting assembly and when the rubber ring clamp 16 faces the pipe fitting. This can prevent the third cylinder 21 from extending or retracting excessively, causing the mounting plate 10 to rotate too much.

[0026] Working principle:

[0027] First, the pipe fittings are conveyed onto the turntable 2 via an external conveyor. After the device is started, the turntable 2 is driven to rotate by an external motor, delivering the pipe fittings to the designated workstation. Simultaneously, the rubber rings are conveyed via a rubber ring conveying device and a conveyor plate 6 to the inclined fixed block 8. A retaining ring cylinder 7 drives two retaining ring grippers 9 to position and clamp the rubber rings on the fixed block 8. A sensor 23 at the end of the fixed block 8 continuously monitors the presence of the rubber rings.

[0028] Once the rubber ring and the fitting are in place, the mounting plate 10 rotates under the drive of the third cylinder 21, causing the opening cylinder 12 and its end rubber ring clamp 16 to face the rubber ring positioned and clamped on the fixing block 8. The first cylinder 11 pushes the slider 15 to move along the slide rail 14, causing the rubber ring clamp 16 to approach and insert into the inner hole of the rubber ring; the opening cylinder 12 extends, driving the rubber ring clamp 16 to open and clamp the rubber ring. After the rubber ring clamp 16 clamps the rubber ring, the first cylinder 11 drives the slider 15 to retract. Subsequently, the mounting plate 10 rotates through the rotating shaft 19 under the drive of the third cylinder 21, causing the rubber ring clamp 16 and the clamped rubber ring to turn towards the fitting. When the rubber ring clamp 16 is aligned with the fitting, the first cylinder 11 drives the sliding mechanism to bring the rubber ring clamp 16 closer to the fitting, and the second cylinder 13 pushes the sliding frame 17 and the ejector plate 18 forward, ejecting the rubber ring from the rubber ring clamp 16 and fitting it onto the end of the fitting. After the fitting is completed, each cylinder resets, and the mounting plate 10 rotates back to its initial position under the retraction of the third cylinder 21. The limit bolt 25 and the hydraulic buffer 26 work together to ensure accurate rotation angle and avoid over-rotation. The entire process is repeated cyclically to achieve automatic fitting of the pipe fitting.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
