Description

Technical Field

[0001] This utility model relates to the field of pipe welding equipment, and in particular to a pipe fitting docking aid. Background Technology

[0002] In the field of building construction, pipe fittings are a key component in constructing various pipeline systems, covering multiple important systems such as water supply and drainage, heating, ventilation, air conditioning, and fire protection.

[0003] When welding pipe fittings, the adjacent ends of two pipe fittings are aligned, and the gap between the two pipe fittings is welded shut with a welding gun, making the two pipe fittings a single unit, thus increasing the length of the pipe fitting.

[0004] Currently, many pipe fitting connection operations still rely heavily on manual experience. It is not easy to align adjacent ports between pipe fittings, which can lead to misalignment during welding. Misalignment affects the quality of welding between pipe fittings, and consequently affects the improvement of the qualified rate of welded pipe processing. Utility Model Content

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example 1 See Figures 1 to 5 This utility model provides a pipe fitting docking aid, including a base 1, on which two n-shaped fixing clips 2 are rotatably arranged. One end of the opening of the fixing clip 2 is rotatably connected to the base 1, and the other end is detachably connected to the base 1. The movable end of the fixed clamp 2 is rotatably equipped with a locking hook 3, and a locking groove 4 is opened on the base 1. The locking hook 3 and the locking groove 4 are detachably connected. A torsion spring is provided between the locking hook 3 and the fixing clamp 2. The elastic force of the torsion spring can ensure that the locking hook 3 remains stable in the locked state and will not easily loosen, thereby further enhancing the clamping force and stability of the fixing clamp 2 on the pipe fitting 16. Two sets of V-shaped pads 5 are fixedly installed on the base 1, and each set of pads 5 corresponds to one of the fixing clips 2; A slider 6 is slidably installed inside the fixed clamp 2. An inverted V-shaped clamping block 7 is fixedly installed on the slider 6. A lifting rod 8 is fixedly installed on the side of the slider 6 away from the clamping block 7. The lifting rod 8 is slidably connected to the fixed clamp 2.

[0023] Loosen the detachable connection between the open end of the fixing clamp 2 and the base 1, and then rotate the fixing clamp 2 outward to a suitable angle with its rotation connection point with the base 1 as the axis, so that it is in a fully open state, providing sufficient space for the placement of the pipe fitting 16. The pipe fitting 16 to be welded is placed stably on the corresponding V-shaped pad 5 on the base 1. The design of the V-shaped pad 5 can adapt well to the circular surface of the pipe fitting 16, providing initial positioning and support for the pipe fitting 16, ensuring that the pipe fitting 16 will not roll randomly during placement, and that its axial direction is roughly consistent with the expected docking direction. Rotate the fixing clamp 2 back to its original position around the rotating connection point, and reconnect the open end of the fixing clamp 2 to the base 1 so that the locking hook 3 is inserted into the locking groove 4. At this time, the pipe fitting 16 is initially fixed in the fixing clamp 2, but there is still a certain amount of room for movement so as to make subsequent precise adjustments.

[0024] According to the diameter of the pipe fitting 16 and the specific welding requirements, the position of the clamping block 7 is adjusted by operating the lifting rod 8 on the slider 6. Pushing the lifting rod 8 up or down will cause the slider 6 to slide in the fixed clamp 2, thereby causing the inverted V-shaped clamping block 7 on the slider 6 to descend and adjust the clamping block 7 to a height that is in close contact with the surface of the pipe fitting 16 and can provide uniform pressure, ensuring that the clamping block 7 can stably clamp the pipe fitting 16 without causing excessive squeezing damage to the surface of the pipe fitting 16. When the clamping block 7 presses down on the pipe fitting 16, the clamping block 7 exerts a reaction force on the fixed clamp 2, making the connection between the locking hook 3 and the locking groove 4 more tightly subjected to force. This is because the reaction force generated when the clamping block 7 presses down on the pipe fitting 16 will be transmitted to the locking hook 3 through the fixed clamp 2, causing the locking hook 3 to be more firmly embedded in the locking groove 4. With the V-shaped pad 5 and the adjustable clamp 7, the pipe fitting 16 can be accurately positioned in the required position, ensuring that the axes of the two pipe fittings 16 are on the same straight line, which greatly improves the alignment accuracy during welding. This is crucial for ensuring welding quality and can effectively reduce welding defects caused by inaccurate pipe fitting 16 connection, such as misalignment and skewness, thereby improving the strength and sealing of the welded joint. A pressure rod 9 is rotatably mounted on the fixed clamp 2, and a connecting rod 10 is rotatably mounted in the middle of the pressure rod 9. The connecting rod 10 is rotatably connected to the upper end of the lifting rod 8. A spring 11 is fitted on the outside of the lifting rod 8. The upper end of the spring 11 is fixedly connected to the upper end of the lifting rod 8, and the lower end is fixedly connected to the fixing clamp 2.

[0025] Hold one end of the pressure rod 9 and apply downward pressure to make the pressure rod 9 rotate around the rotational connection point with the fixed clamp 2. When the pressure rod 9 rotates, the connecting rod 10, which is rotatably set in the middle, will rotate with the movement of the pressure rod 9. Since the other end of the connecting rod 10 is rotatably connected to the upper end of the lifting rod 8, the rotation of the connecting rod 10 will drive the lifting rod 8 to slide downward in the fixed clamp 2. As the lifting rod 8 slides downward, the spring 11 sleeved on its outer side will be compressed. At the same time, the movement of the lifting rod 8 will drive the slider 6 and the inverted V-shaped clamp 7 on the slider 6 to move downward together, so that the clamp 7 can fit tightly against the surface of the pipe fitting 16 and effectively clamp the pipe fitting 16.

[0026] A ratchet 12 is fixedly mounted on the pressure rod 9. The ratchet 12 is coaxial with the rotation axis of the pressure rod 9. A pawl 13 is rotatably mounted on the fixed clamp 2. The pawl 13 cooperates with the ratchet 12.

[0027] Since a ratchet 12 is fixedly installed on the pressure rod 9, and the ratchet 12 is coaxial with the rotation axis of the pressure rod 9, the ratchet 12 will rotate together with the pressure rod 9. When the pressure lever 9 is pressed down, causing the ratchet 12 to rotate, the pawl 13 will slide between the teeth of the ratchet 12, allowing the ratchet 12 to rotate clockwise, thereby realizing the pressing operation of the pressure lever 9. However, once the pressure lever 9 has a tendency to reverse upward (for example, due to an unexpected external force or operational error, an attempt is made to lift the pressure lever 9), the pawl 13 will be locked between the teeth of the ratchet 12, preventing the ratchet 12 from rotating counterclockwise, thus limiting the reverse rotation of the pressure lever 9. This ensures that once the pressure lever 9 is pressed down, it will not easily spring back, thereby ensuring that the clamping force of the clamping block 7 on the pipe fitting 16 will not be accidentally lost.

[0028] A torsion spring is provided between the pawl 13 and the fixing clamp 2.

[0029] After the pipe fitting 16 is welded, the fixed state of the pipe fitting 16 needs to be released. First, the elastic force of the torsion spring on the pawl 13 needs to be overcome, and the pawl 13 needs to be disengaged from the teeth of the ratchet 12 so that it is temporarily disengaged from the engagement relationship with the ratchet 12. In this way, the lifting rod 8 slides upward under the action of the spring 11, which drives the clamping block 7 to move upward and loosens the clamping on the pipe fitting 16.

[0030] Slide grooves 14 are provided on both sides of the slider 6, and slide rails 15 are provided on both sides of the inner wall of the fixing clamp 2. The slider 6 is slidably connected to the slide rails 15 through the slide grooves 14.
