The embodiments of this utility model will be described below based on its overall structure.

[0024] Reference Figure 1In this embodiment of the utility model, the metal pipe weld polishing device includes: a device panel assembly 1, an angle adjustment assembly 2 rotatably connected to one outer end of the device panel assembly 1, a polishing and grinding assembly 3 provided at one inner end of the device panel assembly 1, a handle assembly 4 fixedly provided on one upper side of the device panel assembly 1, a device panel assembly 5 fixedly provided at one end of the polishing and grinding assembly 3, and a motor assembly 6 fixedly provided at the other inner end of the device panel assembly 1.

[0025] Reference Figure 3 The device panel assembly 1 includes a device panel body 10. Locking screw holes 11 are provided through the inner two ends of the device panel body 10. A tension roller bearing 12 is provided through the outer end of the inner middle of the device panel body 10.

A handle fixing through hole 15 is provided through the upper other end of the device panel body 10. A grinding roller bearing 16 is provided through the lower end of the device panel body 10.

[0026] Reference Figure 4 The angle adjustment assembly 2 includes an adjustment roller 20, a magnet ring 21 fixedly sleeved on the outside of the adjustment roller 20, a locking arm 22 rotatably connected to one end of the adjustment roller 20, a through hole 23 through one end of the locking arm 22, and anti-slip grooves 24 around the outside of the through hole 23 at one end of the locking arm 22. A synchronous arm 25 rotatably connected to the other end of the adjustment roller 20, a synchronous gear 26 fixedly installed at one end of the synchronous arm 25, and the through hole 23 is adapted to the locking screw hole 11. The angle adjustment assembly 2 is provided in two sets.

[0027] The above solution involves simultaneously rotating two sets of angle adjustment components 2. Through the meshing of two sets of synchronous gears 26, the two sets of angle adjustment components 2 can rotate at the same angle. By rotating and adjusting the opening angle of the two sets of angle adjustment components 2, the distance between the outer polishing belt 31 of the polishing roller 37 and the weld can be adjusted. This allows for flexible adjustment to meet different usage requirements. After adjusting to the appropriate angle, the locking bolts installed through the two sets of transition holes 23 are screwed into the locking screw holes 11 and tightly fitted with the anti-slip ring pattern 24 to complete the angle positioning. At this time, the magnetic rings 21 in the two sets of angle adjustment components 2 are attached to the surface of the metal pipe to complete the adhesion and adsorption. Then, by holding the handle assembly 4 and pushing and pulling the polishing device back and forth, the weld can be quickly polished, making the use more convenient.

[0028] Reference Figure 5The polishing and grinding assembly 3 includes a transmission base belt 30, a polishing and grinding belt 31 fixedly disposed on the outer side of the transmission base belt 30, a drive roller 32 attached to the upper inner side of the transmission base belt 30, a drive roller shaft 33 fixedly passing through the inside of the drive roller 32, a drive roller pulley 34 fixedly sleeved on one end of the outer side of the drive roller shaft 33, a tension roller 35 attached to one end of the inner side of the transmission base belt 30, a tension roller shaft 36 fixedly passing through the inside of the tension roller 35, a grinding roller 37 attached to the lower inner side of the transmission base belt 30, a grinding roller shaft 38 fixedly passing through the inside of the grinding roller 37, a drive roller bearing 13 and a drive roller bearing 52 fixedly passing through the drive roller shaft 33, a tension roller bearing 12 and a tension roller bearing 51 fixedly passing through the tension roller shaft 36, and a grinding roller bearing 16 and a grinding roller bearing 53 fixedly passing through the grinding roller shaft 38.

[0029] Using the above scheme: drive roller 32 drives transmission base belt 30 and polishing belt 31 to rotate. At the same time, tension roller 35 and polishing roller 37 will rotate simultaneously. By holding handle assembly 4, the outer polishing belt 31 of polishing roller 37 can be attached to the weld seam of metal pipe to carry out polishing work.

[0030] Reference Figure 6 The second device panel assembly 5 includes a second device panel body 50. A tension roller bearing 51 is embedded through the middle of the outer end of the second device panel body 50. A drive roller bearing 52 is embedded through the upper middle of the second device panel body 50. A handle fixing through hole 54 is opened through the other upper end of the second device panel body 50. A grinding roller bearing 53 is embedded through the lower end of the second device panel body 50.

[0031] Reference Figure 7 The motor assembly 6 includes a drive motor 60, one end of which is rotatably connected to a motor shaft 61. A motor pulley 62 is fixedly sleeved on the outer side of one end of the motor shaft 61. A motor bearing 14 is fixedly passed through the motor shaft 61. The motor pulley 62 is connected to the drive roller pulley 34 through a belt structure.

[0032] The above solution is adopted: the drive motor 60 drives the motor shaft 61 to drive the motor pulley 62 to rotate, thereby driving the drive roller pulley 34 to rotate through the belt structure, thus driving the polishing and grinding assembly 3 to operate as a whole.

[0033] The working principle of this utility model is as follows: During use, the drive motor 60 drives the motor shaft 61 to rotate the motor pulley 62, which in turn drives the drive roller pulley 34 to rotate via the belt structure. This drives the drive roller 32 and drive roller shaft 33 to rotate. At this time, the drive roller 32 drives the transmission base belt 30 and polishing belt 31 to rotate. Simultaneously, the tension roller 35 and polishing roller 37 rotate. By holding the handle assembly 4, the outer side of the polishing belt 31 of the polishing roller 37 is brought into contact with the weld seam of the metal pipe to perform polishing work. During polishing, the two sets of angle adjustment components 2 are rotated simultaneously, and the two sets of meshing synchronous gears 26... The two sets of angle adjustment components 2 can rotate at the same angle. By rotating and adjusting the opening angle of the two sets of angle adjustment components 2, the distance between the outer polishing belt 31 of the polishing roller 37 and the weld can be adjusted. This allows for flexible adjustment to meet different usage needs. After adjusting to the appropriate angle, the locking bolts installed through the two sets of transition holes 23 are screwed into the locking screw holes 11 and tightly fitted with the anti-slip ring pattern 24 to complete the angle positioning. At this time, the magnetic rings 21 in the two sets of angle adjustment components 2 are attached to the surface of the metal pipe to complete the adhesion and adsorption. Then, by holding the handle component 4 and pushing and pulling the polishing device back and forth, the weld can be quickly polished, making it more convenient to use.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
