[0016] To better understand the purpose, structure, and function of this invention, the following detailed description of a tee fitting processing device is provided in conjunction with the accompanying drawings.

[0017] like Figures 1 to 4 As shown, a tee pipe processing device of the present invention includes a support frame, a base 2 for placing a tee pipe 4 inside the support frame, a first push rod 5 on the support frame, a pressure plate 6 for pressing the tee pipe 4 on the first push rod 5, and a grinding component for processing the pipe opening on the side wall of the pressure plate 6 corresponding to the pipe opening position of the tee pipe 4. The grinding component can simultaneously grind and process the three pipe openings of the tee pipe 4 after it is fixed, which is convenient to operate, saves time, and improves work efficiency.

[0018] Specifically, the bracket 3 consists of a base plate 1 and a support 3 mounted on the base plate 1. The base 2 for placing the T-tube 4 is located in the middle of the top surface of the base plate 1. The first push rod 5 is mounted on the support 3 and is connected to an external power supply. The telescopic end of the first push rod 5 is set downwards. The pressure plate 6 is mounted on the telescopic end of the first push rod 5. After the T-tube 4 is placed on the base 2, it will be located below the pressure plate 6. When the first push rod 5 is activated, the first push rod 5 drives the pressure plate 6 to press down, thereby fixing the position of the T-tube 4. The grinding assembly for grinding the end face of the pipe opening specifically includes a support arm 9 provided on the side wall of the pressure plate 6. The support arm 9 extends outward on the pressure plate 6. A second push rod 10 is provided on the support arm 9. The second push rod 10 is connected to an external power supply. The second push rod 10 is located on the top surface of the support arm 9 and is fixed by a buckle. A connecting plate 11 is also slidably provided on the support arm 9. A guide groove is opened on the support arm 9 corresponding to the position of the connecting plate 11 for sliding. A second drive motor 12 is provided on the connecting plate 11. The second drive motor 12 is connected to an external power supply. A grinding disc 13 is provided on the output end of the second drive motor 12. The end face of the three-way pipe 4 is ground by the grinding disc 13. When it is necessary to grind the end face of the pipe opening, the first push rod 5 is activated. The first push rod 5 drives the pressure plate 6 and the grinding components on it to move downward. After the pressure plate 6 presses and fixes the tee pipe 4 placed on the base 2, the grinding discs 13 on each grinding component correspond to the end faces of the tee pipe 4. Then, the second push rod 10 and the second drive motor 12 are activated. The second push rod 10 drives the corresponding connecting plates 11 to move on the support arm 9. The second drive motor 12 set on the connecting plate 11 drives the grinding discs 13 connected to its output end to move towards its end face and perform the grinding work on the end face of the corresponding tee pipe 4. In this way, the grinding work of burrs, protrusions and pits on the end faces of each tee pipe 4 is completed in one go. The operation is simple and convenient.

[0019] like Figure 1 and Figure 2As shown, a positioning part 8 is also provided on the pressure plate 6. The positioning part 8 can facilitate the positioning of the three-way pipe 4 and fix the three-way pipe 4 at the same position on the base 2, so as to facilitate the grinding of the pipe opening of the three-way pipe 4 by the grinding assembly. The positioning part 8 specifically includes a through groove 85 opened on the pressure plate 6, and the through groove 85 is opened in front of the pressure plate 6 corresponding to the center pipe direction of the three-way pipe 4. Furthermore, a first positioning plate 81 and a second positioning plate 82 are slidably arranged in the through groove 85, and the first positioning plate 81 and the second positioning plate 82 are symmetrically arranged with respect to the midpoint of the pressure plate 6. At the same time, a screw 83 is rotatably arranged in the through groove 85, and the screw 83 is arranged along the length direction of the through groove 85. One end of the screw 83 passes through the pressure plate 6, and the first positioning plate 81 and the second positioning plate 82 are both threadedly connected to the screw 83. A first drive motor 84 is provided on the side wall of the pressure plate 6. The first drive motor 84 is connected to an external power supply and is connected to the screw 83. The screw 83 has a two-way thread that can rotate in both directions. The first positioning plate 81 and the second positioning plate 82 are respectively connected to the threaded positions in both directions, so that the first positioning plate 81 and the second positioning plate 82 can move relative to each other when the screw 83 rotates.

[0020] When it is necessary to adjust the distance between the first positioning plate 81 and the second positioning plate 82 on the positioning part 8, the first drive motor 84 drives the screw 83 connected to its output end to rotate, and the first positioning plate 81 and the second positioning plate 82, which are threadedly connected to the screw 83, move closer to each other. When it is necessary for the first positioning plate 81 and the second positioning plate 82 to move further apart, the first drive motor 84 can be reversed. The first drive motor 84 will also drive the screw 83 to reverse, and the first positioning plate 81 and the second positioning plate 82, which are threadedly connected to the screw 83, will move further apart. In this way, the tee pipe 4 can be positioned by the positioning part 8 according to the maximum diameter of the middle pipe of the tee pipe 4, so that the center of the tee pipe 4 of different sizes can be aligned with the center of the base 2 under the action of the positioning part 8. When grinding the end face of the pipe, the pressure plate 6 drives the positioning part 8 to descend. The first positioning plate 81 and the second positioning plate 82 on the positioning part 8 push the tee pipe 4, which is off-center from the center of the base 2, so that its center position moves to the center of the base 2 and coincides with the center of the base 2. Then the pressure plate 6 presses and positions the tee pipe 4. Of course, in order to prevent the first positioning plate 81 and the second positioning plate 82 from damaging the tee pipe 4 during descent, the bottom ends of the first positioning plate 81 and the second positioning plate 82 are chamfered, and they can be rounded or beveled.

[0021] Preferably, the grinding disc 13 has symmetrically arranged grooves 14 along its radial direction, and a first cutting part 15 and a second cutting part 16 are respectively slidably arranged in each groove 14. The first cutting part 15 and the second cutting part 16 can clean and cut burrs, protrusions and pits inside and outside the opening of the tee pipe 4. Specifically, the first cutting part 15 includes a first cutting blade 152 slidably arranged in its corresponding groove 14, and a first threaded rod 151 rotatably arranged in the groove 14. The free end of the first threaded rod 151 is provided with a first turntable 153. By rotating the first threaded rod 151, the radial distance of the first cutting blade 152 on the grinding disc 13 can be changed. The second cutting part 16 includes a second cutting blade 162 slidably arranged in its corresponding groove 14, and a second threaded rod 161 rotatably arranged in the groove 14. The free end of the second threaded rod 161 is provided with a second turntable 163. By rotating the second turntable 163, the radial distance of the second cutting blade 162 on the grinding disc 13 can be changed. The first cutting blade 152 and the second cutting blade 162 are cross-shaped, and the sliding groove 14 for their sliding is also cross-shaped. This limits the movement of the first cutting blade 152 and the second cutting blade 162 within the sliding groove 14, ensuring that they can only move along their respective corresponding first threaded rods 151 and second threaded rods 161 within the sliding groove 14. The first cutting blade 152 can cut the inner wall of the pipe opening, and the second cutting blade 162 can cut the outer wall of the pipe opening. When adjusting the first cutting part 15, the first turntable 153 can be rotated. The first turntable 153 drives the first threaded rod 151 to rotate, and the first cutting blade 152, which is threadedly connected to the first threaded rod 151, will move within its corresponding sliding groove 14. When the first cutting blade 152 moves to the appropriate position, the rotation of the first turntable 153 is stopped. When the second cutting blade 162 needs adjustment, the second turntable 163 can be rotated. The second turntable 163 drives the second threaded rod 161 to start rotating, and the second cutting blade 162, which is threadedly connected to the second threaded rod 161, will move in its corresponding slide groove 14. It can be stopped when it moves to the appropriate position. It should be noted that the longitudinal axis of the grinding disc 13 corresponding to each pipe opening of the tee pipe 4 coincides with the axis of the pipe opening of the fixed tee pipe 4. When the pressure plate 6 descends and fits against the tee pipe 4, the transverse center of the grinding disc 13 coincides with the transverse center of the pipe opening. Thus, when the grinding disc 13 rotates to grind the corresponding pipe opening, the center line of the grinding disc 13 coincides with the center line of the pipe opening, which facilitates the cutting treatment of the inner and outer walls of the pipe opening by the first cutting blade 152 and the second cutting blade 162.

[0022] To facilitate the position adjustment of the grinding components mounted on both sides of the pressure plate 6, a U-shaped frame 17 is slidably mounted on the pressure plate 6, and a third push rod 18 is provided between the pressure plate 6 and the U-shaped frame 17. The third push rod 18 is connected to an external power supply, and the U-shaped frame 17 is connected to the support arms 9 of the two extension arms of the corresponding U-shaped frame 17. When a different size tee pipe 4 is replaced and the position of the grinding components on both sides of the pressure plate 6 needs to be adjusted, the third push rod 18 can be activated. The third push rod 18 drives the U-shaped frame 17 to move on the pressure plate 6, and the grinding components connected to the U-shaped frame 17 will move accordingly, thereby completing the movement of the grinding components and enabling the longitudinal axis of the grinding disc 13 to coincide with the center of the pipe openings on both sides of the tee pipe 4 fixed on the base 2.

[0023] As another preferred embodiment, pressure-stopping parts 7 are also distributed on the pressure plate 6. Multiple pressure-stopping parts 7 are evenly spaced on the pressure plate 6, and these parts can adapt to the clamping and limiting of tee pipes 4 of different sizes, facilitating the use of tee pipes 4 of different sizes in the tee pipe fitting processing device. The pressure-stopping part 7 includes a pressure rod 71 slidably disposed on the pressure plate 6, with a limiting piece 72 at the top of the pressure rod 71 and a pressure-stopping ball 73 at the bottom. The pressure-stopping ball 73 can better contact the arc-shaped surface of the tee pipe 4, preventing damage between the pressure rod 71 and the tee pipe 4. Simultaneously, a spring 74 is sleeved on the pressure rod 71 between the pressure-stopping ball 73 and the pressure plate 6. When the pressure plate 6 and its pressure-stopping parts 7 are needed to press down on the tee pipe 4 to limit its movement, the first push rod 5 is activated. The first push rod 5 drives the pressure plate 6 to descend. The pressure-stopping parts 7 on the pressure plate 6 descend with the pressure plate 6. The pressure-stopping parts 7 that first contact the surface of the tee pipe 4 will compress the spring 74. The pressure plate 6 will continue to move downward to allow other pressure-stopping parts 7 to contact the tee pipe 4, thereby increasing the contact area between the pressure-stopping parts 7 on the pressure plate 6 and the tee pipe 4, and better improving the stability of the tee pipe 4 when it is being ground by the grinding disc 13. When the first push rod 5 drives the pressure plate 6 to move upward, the compressed spring 74 will push the pressure rod 71 downward to its initial position through the pressure-stopping ball 73, and limit the pressure rod 71 through the limiting piece 72 to prevent the pressure rod from detaching from the pressure plate 6.

[0024] Instructions for use: Place the T-connector 4 on the base 2 and ensure it is flush against the inner wall of the base 2. Then, activate the first push rod 5 and the second drive motor 12. The first push rod 5 moves the pressure plate 6 and its pressure-stopping part 7 downwards. The positioning part 8 will move the T-connector 4, which is off-center from the base 2, to a new position. Then, the pressure-stopping part 7 will be flush against the surface of the T-connector 4 to fix its position. Activate the second push rod 10, which moves the connecting plate 11. The connecting plate 11, through the second drive motor 12, moves the grinding disc 13 toward its corresponding port. The position is moved and it is polished. The first cutting blade 152 and the second cutting blade 162 set on the grinding disc 13 will also cut the burrs, protrusions and pits on the inner and outer walls of the pipe opening. After the processing is completed, the second push rod 10 is started again. The second push rod 10 drives the grinding disc 13 on the connecting plate 11 and the second drive motor 12 away from its corresponding tee pipe 4 opening and moves to the initial position. Then the first push rod 5 works again, and through the pressure plate 6, it drives the pressure stop part 7 and the polishing assembly on the pressure plate 6 to move upward to the initial position. Finally, the processed tee pipe 4 can be taken away.
