[0039] The grinding device disclosed in Embodiment 2 of the present invention has a structure that is basically the same as that in Embodiment 1. The difference is that a stepper motor is provided on one side of the drive shaft connected to the drive bevel gear 4. When the grinding disc 3 is rotating for grinding, it is driven to rotate at high speed. At this time, the control motor 25 is connected to the shaft 19. When the three grinding rods 15 need to rotate at high speed, the drive bevel gear 4 drives the grinding disc 3 to rotate, and the grinding rods 15 are used to grind the inner and outer diameters of the cut end face of the welded pipe fittings respectively.

[0040] The grinding device disclosed in Embodiment 3 of the present invention has a structure that is basically the same as that in Embodiment 2. The difference is that a transmission rod 10 is vertically inserted into the center of the slide groove through a bearing. The transmission rod 10 is movably inserted into the transmission sleeve rod 9. The transmission rod 10 is arranged in a prismatic structure on one side of the slide groove. When the movable slider 8 is adjusted with the adjustment plate 6, the connection and transmission between the transmission rod 10 and the transmission sleeve rod 9 are not affected.

[0041] The grinding device disclosed in Embodiment 4 of the present invention has a structure that is basically the same as that in Embodiment 3. The difference is that the three grinding blocks 20 are respectively set with grooves extending from one side to grind the cut end face of the welded pipe fitting, and are easy to disassemble and replace.

[0042] The grinding device disclosed in Embodiment 5 of the present invention has a structure that is basically the same as that in Embodiment 4. The difference is that the joint and the mating groove are correspondingly arranged, and both the joint and the mating groove are prismatic structures. When the control motor 25 moves toward the mating shaft 19, it drives the mating shaft 19 to rotate, thereby driving the three grinding rods 15 to rotate synchronously.

[0043] In use, the cutting machine on the pipe processing workbench 1 performs end cutting of the butt-welded pipe fittings. After cutting, the fittings are coaxially mounted on one side of the grinding disc 3 using a common clamping and fixing device. The drive shaft drives the bevel gear 4 to rotate the grinding disc 3 at high speed, performing flat grinding on the end of the butt-welded pipe fitting. During grinding, the three grinding rods 15 are kept out of contact with the butt-welded pipe fitting. Then, according to the diameter of the butt-welded pipe fitting, the extension ring of the rotating adjustment disc 6 is rotated, driving the adjustment disc 6 to rotate and simultaneously moving the three movable sliders 8, causing them to move the grinding rods 15 to the appropriate position. Then, the telescopic rod 24 is pushed to drive the control motor 25 to insert the butt joint into the butt groove of the butt joint shaft 19, driving the second bevel gear 18 and the three first bevel gears 17 to rotate. In turn, the transmission rod 10 drives the transmission sleeve rod 9 and the assembly shaft 14 to rotate at high speed. Then, the grinding rod 15 grinds the inner and outer diameters of the butt welded pipe fittings. During the grinding, the driving bevel gear 4 drives the grinding disc 3 to rotate slowly, achieving the effect of grinding the inner and outer diameters in all directions. In addition, when the movable slider 8 moves with the adjusting thread of the adjusting disc 6, the transmission sleeve rod 9 slides along the transmission rod 10 to maintain a stable transmission connection.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
