[0033] A threaded pipe cutting end face polishing device, which structure can be composed of Figures 1-5The embodiment is illustrated. In the embodiment, the threaded pipe cutting end face polishing device comprises an operation table, a driving assembly and a polishing assembly, wherein the driving assembly and the polishing assembly are arranged on the operation table. In use, the worker can first place the threaded pipe 9 between the driving assembly and the polishing assembly, then abut the threaded pipe 9 against the polishing assembly by means of the driving assembly, and drive the threaded pipe 9 to rotate, so that the polishing assembly can polish the cutting end face of the threaded pipe 9, remove sharp edges and burrs on the threaded pipe 9, and make the threaded pipe 9 form a smooth and flat cutting end face, thereby improving the subsequent welding effect of the threaded pipe 9.

[0034] Specifically, as shown in Figure 1 and Figure 2 , the operation table is provided with a driving area 11, a bearing area and a polishing area 13 arranged in sequence, wherein the bearing area is internally provided with a plurality of rotatable bearing rollers 12, and the plurality of bearing rollers 12 are parallel to each other. When the worker places the threaded pipe 9 to be processed between the driving assembly and the polishing assembly, the side wall of the bearing roller 12 will be in contact with the outer side wall of the threaded pipe 9, and the bearing roller 12 can rotate with the threaded pipe 9 when the threaded pipe 9 rotates, thereby reducing the rotation difficulty of the threaded pipe 9.

[0035] As shown in Figure 4 , the driving assembly comprises a first mounting plate 21, a second mounting plate 22 and a pipe plug, wherein the first mounting plate 21 is arranged in the driving area 11 in a lifting manner, the second mounting plate 22 is arranged on the first mounting plate 21 in a sliding manner, and the sliding direction of the second mounting plate 22 is parallel to the axis direction of the bearing roller 12. A rotating motor 3 is further arranged on the second mounting plate 22, the output shaft of the rotating motor 3 is parallel to the bearing roller 12, and the pipe plug is detachably arranged on the output shaft of the rotating motor 3. After the threaded pipe 9 is placed in the device, the worker can first align the pipe plug with the threaded pipe 9 by lifting the first mounting plate 21, then make the pipe plug close to the threaded pipe 9 by sliding the second mounting plate 22, and finally make the pipe plug inserted into one end of the threaded pipe 9. At this time, the threaded pipe 9 will be pushed by the driving assembly to the direction where the polishing assembly is located, so that the end of the threaded pipe 9 abuts against the polishing assembly. Next, the worker can start the rotating motor 3, thereby driving the threaded pipe 9 to rotate by means of the rotating motor 3, so that the threaded pipe 9 and the polishing assembly move relative to each other, thereby making the polishing assembly polish the end of the threaded pipe 9.

[0036] Optionally, in the embodiment, the pipe plug can include a stop disc 41 and a positioning plug 42, wherein the positioning plug 42 is arranged on the end face of the stop disc 41 away from the rotating motor 3, the outer diameter of the positioning plug 42 is smaller than that of the stop disc 41, and a guide cone surface 421 is arranged on the end face of the positioning plug 42 away from the stop disc 41. When the second mounting plate 22 slides towards the threaded pipe 9, the positioning plug 42 will be inserted into the interior of the threaded pipe 9, so that the inner wall of the threaded pipe 9 is in close contact with the outer wall of the positioning plug 42, and the end face of the threaded pipe 9 away from the polishing assembly is in close contact with the stop disc 41, thereby completing the positioning connection between the threaded pipe 9 and the driving assembly by means of the pipe plug.

[0037] In order to realize the lifting action of the first mounting plate 21, a first electric push rod 23 can be arranged on the operation table, and the end of the first electric push rod 23 should be connected with the bottom surface of the first mounting plate 21. Correspondingly, in order to realize the sliding action of the second mounting plate 22, a second electric push rod 24 can be arranged on the first mounting plate 21, and the end of the second electric push rod 24 should be connected with the side wall of the second mounting plate 22 away from the bearing area.

[0038] Optionally, in order to improve the stability of the action of the first mounting plate 21, a guide rod 212 perpendicular to the operation table can be arranged on the bottom surface of the first mounting plate 21, and a guide hole 111 for accommodating the guide rod 212 can be arranged in the driving area 11, thereby guiding the lifting movement of the first mounting plate 21 by means of the cooperation of the guide rod 212 and the guide hole 111. Correspondingly, in order to improve the stability of the action of the second mounting plate 22, a guide strip 211 parallel to the axis direction of the bearing roller 12 can be arranged on the top surface of the first mounting plate 21, and a guide groove for accommodating the guide strip 211 can be arranged on the bottom surface of the second mounting plate 22, thereby guiding the sliding of the second mounting plate 22 by means of the cooperation of the guide strip 211 and the guide groove.

[0039] Figure 5 The exploded view of the polishing assembly in the device is shown in the figure. In the embodiment, the polishing assembly mounting seat 5, the bearing block 6 and the polishing head 7 are arranged. The mounting seat 5 is arranged in the polishing area 13, the bearing block 6 is arranged on the mounting seat 5 in a height-adjustable manner, and the polishing head 7 is arranged on the side wall of the bearing block 6 facing the driving assembly in a detachable manner. Since the cut part of the threaded pipe 9 needs to be polished on the end face, the inner wall and the outer wall at the same time, the inner polishing column 71 and the outer polishing column 72 are arranged on the polishing head 7, wherein the inner polishing column 71 and the outer polishing column 72 are parallel to the bearing roller 12, and a polishing gap for accommodating the end part of the threaded pipe 9 is formed between the inner polishing column 71 and the outer polishing column 72.

[0040] As Figure 3As shown, after the driving assembly abuts the threaded pipe 9 against the polishing assembly, the end face of the threaded pipe 9 will be in contact with the polishing head 7, and the inner polishing column 71 and the outer polishing column 72 will be in contact with the inner side wall and the outer side wall of the threaded pipe 9, respectively. When the threaded pipe 9 rotates, the polishing head 7, the inner polishing column 71 and the outer polishing column 72 will polish the end face, the inner wall and the outer wall of the threaded pipe 9 at the same time, thereby improving the polishing efficiency of the cutting end face of the threaded pipe 9.

[0041] Optionally, in order to reduce the difficulty of inserting the end of the threaded pipe 9 into the polishing gap, the end of the inner polishing column 71 and the outer polishing column 72 away from the polishing head 7 can be provided with a tapered guide head 73, so as to avoid the end face of the threaded pipe 9 from colliding with the inner polishing column 71 or the outer polishing column 72.

[0042] In actual work process, since the threaded pipe 9 has a plurality of different diameter specifications, in order to adapt to the cutting end face polishing work of threaded pipes 9 with different diameters, the height of the bearing block 6 can be adjusted according to actual conditions to ensure that the end of the threaded pipe 9 is smoothly inserted into the inside of the polishing gap.

[0043] In order to realize the height adjustment function of the bearing block 6, the mounting seat 5 can be provided with a containing cutout 51 for accommodating the bearing block 6, and a rotatable adjusting screw 8 is arranged in the containing cutout 51, and the bearing block 6 is provided with an adjusting screw hole 61 for accommodating the adjusting screw 8. When it is necessary to adjust the height of the bearing block 6, the worker can drive the adjusting screw 8 to rotate. Since the inner wall of the containing cutout 51 limits the rotation of the bearing block 6, the bearing block 6 will move along the containing cutout 51 when the adjusting screw 8 rotates, thereby realizing the height adjustment of the bearing block 6.

[0044] In addition, when the diameter specification of the threaded pipe 9 to be processed changes, the worker should also disassemble and replace the pipe plug to ensure that the pipe plug has a good abutting positioning effect on the threaded pipe 9. In order to reduce the disassembly difficulty of the pipe plug, the output shaft end of the rotating motor 3 can be provided with a connecting flange plate 31. When the diameter of the threaded pipe 9 changes, the worker should select the specification of the pipe plug to match the threaded pipe 9 to be processed, and then assemble the pipe plug to the connecting flange plate 31 through the connecting bolt, to complete the assembly between the pipe plug and the connecting flange plate 31.

[0045] Correspondingly, when the wall thickness of the threaded pipe 9 to be processed changes, the worker should also disassemble and replace the polishing head 7, so that the distance between the inner polishing column 71 and the outer polishing column 72 matches the wall thickness of the threaded pipe 9, and ensures that the inner polishing column 71 and the outer polishing column 72 can have a good polishing effect on the inner and outer walls of the threaded pipe 9.

[0046] As an optional implementation of the embodiment, in order to facilitate the collection of the debris generated in the polishing process, the device can be provided with a debris collecting groove 131 in the polishing area 13. Figure 1 As shown in the figure, the debris collecting groove 131 should be located between the mounting seat 5 and the bearing area, so as to facilitate the centralized recovery of the debris falling from the side of the polishing assembly.

[0047] The effects of the above scheme are described as follows:

[0048] The embodiment provides a threaded pipe cutting end face polishing device, which can drive the end of the threaded pipe to abut against the polishing assembly through the driving assembly, and can drive the threaded pipe to rotate, so that the cutting end face of the threaded pipe is polished through the polishing assembly, and the polishing efficiency of the cutting end face of the threaded pipe is improved. Secondly, the height of the polishing head of the device can be adjusted according to the specification of the threaded pipe, and the polishing head and the pipe plug can be disassembled and replaced, so as to adapt to various processing requirements. In addition, the device can polish the end face and the inner and outer side walls of the threaded pipe through the polishing head, the inner polishing column and the outer polishing column at the same time, and therefore has better polishing effect and processing efficiency.

[0049] The above only describes the preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
