Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clamping devices, in particular to a three-way joint clamping device. Background Art
[0002] A tee is a fitting used to connect three pipes. It plays a key role in changing the direction of fluid flow, diverting or merging it, and is widely used in numerous fields, including chemical engineering, petroleum, natural gas, and construction. The tee clamping device is used to securely fasten the tee during machining, installation, or testing, ensuring operational accuracy and stability, safeguarding the safe and efficient operation of the entire piping system and preventing leaks, pressure imbalances, and other issues caused by loose joints.
[0003] Traditional tee clamping devices primarily consist of a fixed base, clamping arms, and a drive screw. The fixed base provides basic support and a mounting platform for the device. There are typically two or three clamping arms, one end of which is connected to the fixed base and allows for a certain degree of rotation through a hinge or other means. The drive screw works in conjunction with the clamping arms. Rotating the drive screw causes the clamping arms to move relative to each other, thereby tightening or loosening the tee positioned between them. These components work together to achieve the basic securing function of the tee.
[0004] From a structural perspective, the clamping method of the traditional three-way joint clamping device cannot be fixed from multiple angles. The number of its clamping arms is limited and the movement method is relatively simple. Most of the time, the joint is clamped by a simple opening and closing action, and there is a lack of multi-directional adjustment and constraint mechanisms. This situation makes it impossible to fully restrict the displacement and rotation of the joint when facing complex working conditions or when there are special fixing requirements for the three-way joint. For example, in some application scenarios of high-precision machining or bearing multi-directional external forces, the joint will shift and tilt due to loose fixation, affecting the machining accuracy, reducing the sealing and reliability of the connection, and even causing leakage and failure of the pipeline system, increasing maintenance costs and safety risks, and limiting its application in a wider range of engineering fields with higher requirements.

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] Reference Figure 1-Figure 2 The utility model provides an embodiment: a three-way joint clamping device, including a workbench 1, a plurality of straight slots 2 are opened inside the workbench 1, a rotating cylinder 3 is provided at the bottom of the workbench 1, and the output end of the rotating cylinder 3 is fixedly connected to a turntable 4, a clamping component is provided on the top of the workbench 1, and an adjusting component is provided at the bottom of the workbench 1, and the adjusting component is used to adjust the angle of the three-way joint;
[0025] The clamping assembly includes a side platform 6, which is fixedly connected to the top of the workbench 1. A connecting platform 7 is fixedly connected between the side platforms 6. A sliding shaft 8 is slidably connected inside the connecting platform 7. One end of the sliding shaft 8 is fixedly connected to a pushing platform 9. A plurality of arc-shaped slide grooves 5 are opened inside the turntable 4. A fixed shaft 10 is fixedly connected to the bottom of the pushing platform 9, and the fixed shaft 10 is slidably connected inside the arc-shaped slide groove 5.
[0026] Specifically, first, when the three-way joint needs to be clamped, the relevant personnel starts the rotating cylinder 3. After the rotating cylinder 3 starts working, it first applies power to the turntable 4 and drives the turntable 4 to rotate. During the rotation process of the turntable 4, the multiple arc chute 5 arranged inside it will undergo centripetal displacement due to the rotation of the turntable 4. At this time, the fixed shaft 10 at the bottom of the push table 9 is inside the arc chute 5 and contacts it. As the arc chute 5 moves centripetally, the fixed shaft 10 will start to slide inside the straight groove 2 under the action of this thrust. The sliding of the fixed shaft 10 further causes the push table 9 on its top to move synchronously. The push table 9 is in the position where the force is generated. After the movement, it will drive the sliding shaft 8 to slide along a specific track inside the connecting platform 7. When multiple push platforms 9 slide between the side platforms 6 at the same time, the three-way joint can be effectively clamped. This multi-angle fixing method can constrain the three-way joint from different directions, effectively preventing the displacement or rotation of the three-way joint caused by insufficient constraint force in a certain direction, thereby effectively ensuring the accuracy and stability of the operation process, further improving the quality level of the product during processing, installation or use, reducing errors or adverse consequences caused by loose clamping, and providing reliable guarantee for the smooth progress of related process flows.
[0027] Reference Figure 3 The adjustment component includes a base 11, which is arranged at the bottom of the workbench 1, and an electric motor 13 is fixedly connected to the top of the base 11, and a transmission column 14 is fixedly connected to the output end of the electric motor 13, and an electric motor 2 16 is fixedly connected to the top of the base 11, and the output end of the electric motor 2 16 is fixedly connected to the transmission column 2 17, and the top of the base 11 is fixedly connected to the vertical plate 12, and the transmission column 14 is rotatably connected to the inside of the left vertical plate 12, and one end of the transmission column 14 is fixedly connected to the worm 15, and the transmission column 2 17 is rotatably connected to the side wall of the right vertical plate 12, and the top of the transmission column 2 17 is fixedly connected to a connecting frame 18, and a worm gear 19 is rotatably connected to the inside of the connecting frame 18, and the worm gear 19 is meshed with the worm 15, and the side wall of the worm gear 19 is fixedly connected to a side frame 20, and the side frame 20 is rotatably connected to the outer wall of the connecting frame 18. The top of the side frame 20 is fixedly connected to a support platform 21, and the support platform 21 is fixedly connected to the bottom of the workbench 1.
[0028] Specifically, when faced with the task of adjusting the angle of the workbench 1 to change the angle of the three-way joint, the electric motor 13 is first started. The electric motor 13 starts to run and outputs power to the transmission column 14, causing the transmission column 14 to rotate inside the vertical plate 12. At the same time as the transmission column 14 rotates, the worm 15 at one end thereof also rotates. Due to the specific meshing relationship between the worm 15 and the worm gear 19, the rotation of the worm 15 further drives the worm gear 19 to start rotating. During the rotation of the worm gear 19, it will drive the side frame 20 of its side wall to rotate. As the side frame 20 rotates, the inclination angle of its top side frame 20 will also change accordingly, and the angle change of the top side frame 20 will directly drive the workbench 1 to change the horizontal angle, thereby realizing the angle adjustment of the three-way joint in the horizontal direction. When the electric motor 2 16 is started, the electric motor 2 16 will drive the transmission column 2 17 rotates on the side wall of the vertical plate 12, and drives the connecting frame 18 on the top of the transmission column 2 17 to rotate together. During the rotation process, the connecting frame 18 will immediately drive the side frame 20 and the support platform 21 of its side wall to rotate. This rotational movement can change the vertical angle of the workbench 1, and achieve the angle change of the three-way joint in the vertical direction, so that the entire device can be flexibly and accurately adjusted according to different installation environments and the specific shape and angle requirements of the three-way joint. This flexible adjustment feature greatly enhances the adaptability of the device to various actual working conditions, so that it can fully play an effective role in a variety of complex and changeable pipeline systems. Whether it is a large-scale pipeline network in industrial production or a small-scale pipeline layout in a building facility, it can meet the needs of three-way joint angle adjustment, ensure the accuracy and stability of the pipeline connection, and improve the installation quality and operation efficiency of the entire pipeline system.
[0029] Working principle: First, when the three-way joint needs to be clamped, the rotating cylinder 3 is started. The rotating cylinder 3 first outputs the turntable 4 to drive the turntable 4 to rotate. During the rotation process, the turntable 4 will drive the multiple arc-shaped slide grooves 5 inside it to move centripetally. Since the fixed shaft 10 at the bottom of the push table 9 slides inside the arc-shaped slide groove 5, the displacement of the arc-shaped slide groove 5 will drive the fixed shaft 10 to slide inside the straight groove 2. The displacement of the fixed shaft 10 further drives the push table 9 on its top to move synchronously. After the push table 9 is subjected to force, it drives the sliding shaft 8 to slide inside the connecting table 7. Multiple push tables 9 slide synchronously between the side tables 6 to achieve effective clamping of the three-way joint. Multi-angle fixation can constrain the three-way joint from all directions to avoid displacement or rotation due to insufficient constraint in a certain direction, which can effectively ensure the accuracy and stability of the operation and improve product quality. When it is necessary to adjust the angle of the workbench 1 to change the angle of the three-way joint, start the electric motor. 13. The electric motor 13 outputs to the transmission column 14 to drive the transmission column 14 to rotate inside the vertical plate 12. At this time, the worm 15 at one end of the transmission column 14 can rotate, and the worm 15 further drives the worm wheel 19 to rotate through the meshing relationship with the worm wheel 19. The rotation process of the worm wheel 19 will drive the side frame 20 of its side wall to rotate and change the inclination angle of the top side frame 20, thereby driving the workbench 1 to change the horizontal angle. Starting the electric motor 2 16 will drive the transmission column 2 17 to rotate on the side wall of the vertical plate 12 and drive the connecting frame 18 on the top of the transmission column 2 17 to rotate. When the connecting frame 18 rotates, it immediately drives the side frame 20 and the support platform 21 of the side wall to rotate, thereby changing the vertical angle of the workbench 1, so that the device can be flexibly adjusted according to different installation environments and the specific shape and angle requirements of the tee joint, thereby enhancing the adaptability of the device to various actual working conditions and enabling it to play an effective role in a variety of piping systems.
