Description

Technical Field

[0001] This invention relates to the field of pipe fitting burr removal technology, specifically to a device for removing burrs at pipe fitting weld joints. Background Technology

[0002] In fields such as pipeline engineering and machinery manufacturing, welding of pipe fittings is one of the key processes for assembling pipeline systems. However, during the welding process, the molten metal at high temperatures forms irregular burrs on the weld edge as it cools and solidifies. These burrs not only affect the appearance quality of the pipe fittings but can also scratch sealing elements, sealing rings, and other supporting components, and in severe cases, can cause safety hazards such as leaks.

[0003] Existing pipe fitting burr trimming equipment typically involves hand-held grinding devices to grind the welded areas. After grinding one area, the grinding device is moved to grind other areas. Since pipes are 360°, some areas cannot be placed with the grinding device during installation, or the angle of holding it is awkward. Furthermore, the sparks generated during grinding can cause injury, making the trimming operation inconvenient. Therefore, it is necessary to propose a pipe fitting weld burr trimming device. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a device for deburring weld joints of pipe fittings.

[0005] The technical solution adopted by this invention to solve its technical problem is: a burr trimming device for pipe fitting welds, comprising a mounting base and a fixing clamp assembly arranged in a semi-circular shape. A first rotating groove is provided on the inner wall of the mounting base. Clamping blocks are provided on the outer sides of both ends of the mounting base. A second rotating groove is provided on each clamping block. A connecting plate is fixedly connected to each clamping block. A threaded hole is provided through the connecting plate. A threaded rod is rotatably connected to the mounting base via a bearing. The threaded rod is threadedly connected to the threaded hole. A mounting frame is fixedly connected to the mounting base. A motor is fixedly mounted on the mounting frame. A drive wheel is fixedly connected to the output end of the motor via a coupling. One end of the drive wheel extends into the first rotating groove and abuts against the fixing clamp assembly. A through hole is provided on the mounting base. The fixing clamp assembly is rotatably connected within the first and second rotating grooves. A mounting groove is provided on the fixing clamp assembly, and a grinding block is fixedly mounted within the mounting groove.

[0006] Specifically, the fixing hoop assembly includes a first clamping ring and a second clamping ring, both of which are rotatably connected in a first rotating groove and a second rotating groove. One end of the first clamping ring and the second clamping ring is fixed by a bolt assembly, and the other end of the first clamping ring and the second clamping ring is connected by a rotating shaft assembly.

[0007] Specifically, the bolt assembly includes mounting holes, which are T-shaped and are respectively opened through the first clamping ring and the second clamping ring. A bolt and a nut are provided in the mounting holes, which are threadedly connected, and the bolt and nut are respectively located in the mounting holes on the first clamping ring and the second clamping ring.

[0008] Specifically, the rotating shaft assembly includes a fixing groove, which is formed on a first clamping ring and a second clamping ring. The rotating shaft is fixedly installed inside the fixing grooves located on the first clamping ring and the second clamping ring.

[0009] Specifically, a mounting rod is fixedly installed on the outer wall of the mounting base, and the rod wall is provided with anti-slip texture.

[0010] Specifically, the end of the threaded rod away from the mounting base passes through the threaded hole and extends outward to the outside of the connecting plate, and the end of the threaded rod located outside the connecting plate is fixedly connected to a rotating handle.

[0011] Specifically, the openings of the first rotating groove and the second rotating groove coincide, and the mounting base abuts against the side wall of the clamping block on the opposite side.

[0012] The beneficial effects of the present invention are as follows: The pipe fitting weld burr removal device of the present invention, in use, involves attaching a fixing hoop to the weld of the pipe fitting, then placing the mounting seat on the fixing hoop, and then driving the clamping block to clamp the pipe fitting, thereby limiting the fixing hoop within the annular rotating groove. The motor can then be started, driving the fixing hoop to rotate on the pipe fitting, and the internal grinding block rotates to grind the weld of the pipe fitting. This allows the device to directly and comprehensively grind and remove burrs from the weld of the pipe fitting without requiring multi-directional adjustments, making it simpler and more convenient to use.

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-6 As shown, the present invention provides the following technical solution: Example 1: A burr trimming device for pipe fitting welds includes a semi-circular mounting base 1 and a fixing clamp assembly. The inner wall of the mounting base 1 has a first rotating groove 2. Clamping blocks 3 are provided on the outer sides of both ends of the mounting base 1. A second rotating groove 4 is provided on each clamping block 3. A connecting plate 5 is fixedly connected to each clamping block 3. A threaded hole 6 is provided through the connecting plate 5. A threaded rod 7 is rotatably connected to the mounting base 1 via a bearing. The threaded rod 7 is threadedly connected to the threaded hole 6. A mounting frame 8 is fixedly connected to the mounting base 1. A motor 9 is fixedly mounted on the mounting frame 8. The output end of the motor 9 is fixedly connected to a drive wheel 10 via a coupling. One end of the drive wheel 10 extends into the first rotating groove 2 and abuts against the fixing clamp assembly. A through hole 11 is provided through the mounting base 1. The fixing clamp assembly is rotatably connected within the first rotating groove 2 and the second rotating groove 4. An installation groove 12 is provided on the fixing clamp assembly, and a grinding block 13 is fixedly installed within the installation groove 12. The fixing hoop assembly includes a first clamping ring 14 and a second clamping ring 15. The first clamping ring 14 and the second clamping ring 15 are rotatably connected in the first rotating groove 2 and the second rotating groove 4. One end of the first clamping ring 14 and the second clamping ring 15 is fixed by a bolt assembly, and the other end of the first clamping ring 14 and the second clamping ring 15 is connected by a rotating shaft assembly. After pipe installation and welding, and when it is necessary to remove burrs from the weld joints, the following steps are included: Step 1: For pipes of the corresponding specifications, place the first clamping ring 14, which corresponds to the pipe diameter, onto the weld joint of the pipe fitting. Then, rotate the second clamping ring 15 through the rotating shaft 20. The first clamping ring 14 and the second clamping ring 15 abut against each other, and the openings of the mounting holes 16 will overlap. Then, insert the bolt 17 and the nut 18 into the mounting holes 16 in the first clamping ring 14 and the second clamping ring 15 respectively. Then, the bolt 17 and the nut 18 can be threaded together by rotating them, and the other ends of the first clamping ring 14 and the second clamping ring 15 are fixedly connected, so that the first clamping ring 14 and the second clamping ring 15 together form a complete circular fixing hoop, which is then placed onto the weld joint of the pipe fitting. The second step is to align the first rotating groove 2 on the mounting base 1 with the fixing hoop, and push the mounting base 1 toward the fixing hoop so that the fixing hoop is engaged in the first rotating groove 2. At this time, the threaded rod 7 can be rotated by rotating the handle 22. The threaded rod 7 drives the connecting plate 5 through the cooperation with the threaded hole 6. The connecting plate 5 drives the clamping block 3 to move toward the fixing hoop and engages the fixing hoop in the second rotating groove 4 on the clamping block 3, so that the fixing hoop can only rotate in the first rotating groove 2 and the second rotating groove 4 and cannot be disengaged. Third step: Hold the mounting base 1 by the mounting rod 21, and then start the motor 9. The motor 9 drives the drive wheel 10 to rotate. The drive wheel 10 rotates by abutting against the fixed hoop. The fixed hoop drives the grinding block 13 installed inside to rotate synchronously. The grinding block 13 will grind the welded joint of the pipe fitting, making the grinding more thorough and requiring no adjustment. Fourth step: After grinding, rotate the threaded rod 7 to drive the clamping block 3 to release the fixing hoop. Then remove the mounting base 1 and disassemble the fixing hoop. This makes the grinding process simpler and more convenient, and avoids the burr trimming process being affected by external obstructions.

[0018] Example 2: The technical solutions in this example that differ from Example 1 include: The bolt assembly includes mounting holes 16, which are T-shaped and pass through the first clamping ring 14 and the second clamping ring 15 respectively. A bolt 17 and a nut 18 are disposed within the mounting holes 16, and are threadedly connected. The bolt 17 and nut 18 are located within the mounting holes 16 on the first clamping ring 14 and the second clamping ring 15 respectively. Through the threaded connection of the bolt 17 and nut 18, the first clamping ring 14 and the second clamping ring 15 are clamped and fixed by abutting against the wall of the mounting holes 16. The rotating shaft assembly includes a fixing groove 19, which is formed on the first clamping ring 14 and the second clamping ring 15. A rotating shaft 20 is fixedly installed within the fixing groove 19 on both the first clamping ring 14 and the second clamping ring 15. One end of the holding ring 15 is rotatably connected via a rotating shaft 20. The other ends of the first clamping ring 14 and the second clamping ring 15 are fixedly connected to the nut 18 via bolts 17. An installation rod 21 is fixedly installed on the outer wall of the mounting base 1. The mounting base 1 can be held by hand via the installation rod 21 for calibration during use. The rod wall of the installation rod 21 is provided with anti-slip texture. The end of the threaded rod 7 away from the mounting base 1 passes through the threaded hole 6 and extends outward to the outside of the connecting plate 5. The end of the threaded rod 7 located outside the connecting plate 5 is fixedly connected to a rotating handle 22. The threaded rod 7 can be rotated by rotating the handle 22. The openings of the first rotating groove 2 and the second rotating groove 4 coincide, and the side wall of the mounting base 1 and the clamping block 3 abuts against each other, which can prevent the clamping block 3 from rotating, so that the threaded hole 6 cannot rotate either. Thus, when the threaded rod 7 rotates, the connecting plate 5 is driven to rise and fall.
