[0002] During the production process of welded pipes, if the welding process is not properly controlled or the raw materials contain impurities, welding spatter, welding slag, oxides or other forms of impurity residues may appear in the weld seam inside the welded pipe.

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.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0026] See also Figure 1-4The utility model provides a technical solution: a welding pipe grinding machine, including a grinding assembly 2, a cleaning assembly 3, a clamping assembly 4 and a driving assembly 5. The driving assembly 5 is arranged on the lower side of the clamping assembly 4, and the welding pipe main body 1 is arranged between the clamping assembly 4 and the driving assembly 5. The grinding assembly 2 is arranged on the left side of the driving assembly 5, and the cleaning assembly 3 is installed on the grinding assembly 2. The grinding assembly 2 includes a hollow shaft motor 21, and the hollow shaft motor 21 is connected to a driving rod 23. The right side of the driving rod 23 is arranged inside the welding pipe main body 1, and a grinding block 24 is fixed on the outer side of the right end of the driving rod 23. The driving rod 23 is a hollow structure. The cleaning assembly 3 includes an air intake port 32, and an air intake port 32 is opened on the right side of the driving rod 23. A windshield block 31 is fixed to the right side of the air intake port 32. The cross-sectional diameter of the windshield block 31 is smaller than the cross-sectional diameter of the grinding block 24. A rotary joint 33 is installed on the left side of the hollow shaft motor 21, and the rotary joint 33 is connected to a negative pressure air source;

[0027] During use, the hollow shaft motor 21 provides power for the grinding process, driving the grinding block 24 to rotate at high speed. The driving rod 23 connects the hollow shaft motor 21 and the grinding block 24 to transmit rotational power. The hollow structure provides the necessary air flow channel for the cleaning component 3. The grinding block 24 is in direct contact with the inside of the weld pipe to perform fine grinding operations to remove unevenness on the inner wall. The air intake 32 uses the suction generated by the negative pressure air source to promptly absorb the fine slag generated during the grinding process. The windshield block 31 is used to reduce the air entering the other end, thereby increasing the suction to the grinding end. The rotary joint 33 is connected between the hollow shaft motor 21 and the negative pressure air source to keep the driving rod 23 connected to the negative pressure air source when rotating, and continuously generate negative pressure suction.

[0028] The connection between the hollow shaft motor 21 and the drive rod 23 is fixed by a connecting rod 22. The connecting rod 22 makes the connection between the hollow shaft motor 21 and the drive rod 23 more stable, and the hollow shaft motor 21 and the drive rod 23 can be separated by removing the connecting rod 22, thereby simplifying the maintenance process.

[0029] The clamping assembly 4 includes a support frame 41, a threaded rod 42 is movably installed on the front side of the support frame 41, an internal thread block 44 is installed on the outside of the threaded rod 42, two groups of first clamping wheels 46 are movably installed on the outside of the internal thread block 44 through bearings 45, and two groups of first clamping wheels 46 are movably installed on the outside of the internal thread block 44 through bearings 45. These clamping wheels can move with the lifting and lowering of the internal thread block 44, and the lifting and lowering of the thread block can be controlled by rotating the threaded rod 42.

[0030] Two sets of second clamping wheels 53 are movably installed at the lower end of the support frame 41. The two sets of second clamping wheels 53 are perpendicular to the first clamping wheels 46. When the first clamping wheels 46 are clamped and released by the lifting and lowering of the threaded rod 42, the second clamping wheels 53 provide additional support and fixation at the lower end of the support frame 41 to ensure that the welded pipe will not move or shake in the vertical direction.

[0031] A wheel disc 421 is fixed to the upper end of the threaded rod 42 . The design of the wheel disc 421 increases the operating area, provides better torque transmission, and enables the threaded rod 42 to be rotated more easily.

[0032] Two sets of guide rods 43 are fixed to the front end of the support frame 41. The guide rods 43 are movably installed on both sides of the internal thread block 44. The function of the guide rods 43 is to ensure that the internal thread block 44 can maintain the correct position and direction during the lifting process.

[0033] The driving assembly 5 includes a driving motor 52. The driving motor 52 is installed at the lower end of the support frame 41 through the motor bracket 51. The driving motor 52 is connected to the second clamping wheel 53 on the left. The two groups of second clamping wheels 53 are connected through a synchronous transmission belt 54. When the welded pipe is clamped by the two groups of second clamping wheels 53, the power of the driving motor 52 can be used to make the welded pipe body 1 rotate and move under the drive of the two groups of second clamping wheels 53. When the second clamping wheel 53 on the left rotates, the second clamping wheel 53 on the right will also rotate synchronously through the transmission action of the synchronous transmission belt 54.

[0034] As an embodiment of the present invention, when the welded pipe grinding machine is used, the position of the first clamping wheel 46 can be easily adjusted by rotating the wheel disc 421 on the threaded rod 42. At the same time, the second clamping wheel 53 also provides necessary support to ensure that the welded pipe body 1 is firmly clamped. The drive motor 52 is started, so that the entire welded pipe body 1 is moved smoothly under the drive of the two sets of clamping wheels.

[0035] When the hollow shaft motor 21 is started, it will provide powerful power to the grinding block 24, making it rotate at high speed. The grinding block 24 is in direct contact with the inside of the weld pipe. During the grinding process, the grinding block 24 will effectively remove the uneven parts of the inner wall of the weld pipe. Since the driving rod 23 is a hollow structure, it provides an air flow channel. When fine slag is generated during the grinding process, the suction port 32 will use the suction generated by the negative pressure air source to suck in the fine slag in time, and the design of the wind shield block 31 cleverly reduces the air entering the other end, thereby increasing the suction to the grinding end, making the suction effect more significant. The rotary joint 33 is connected between the hollow shaft motor 21 and the negative pressure air source, which ensures that the driving rod 23 can still maintain communication with the negative pressure air source during rotation, thereby continuously generating negative pressure suction. The fine slag generated during the grinding process will be continuously sucked in and discharged through the air flow channel, effectively keeping the inside of the weld pipe clean and improving the efficiency and quality of the grinding.
