In order to avoid left and right misalignment of the steel pipes stacked up and down, the steel pipe positioning assembly also includes a right baffle 26 arranged on the processing table 11, and a left baffle 62 fixed on the processing table 11. The right baffle 26 is located on the right side of the side baffle 21, and the length of the steel pipe is adapted to the distance between the right baffle 26 and the left baffle 62. The left baffle 62 and the right baffle 26 are respectively attached to the left and right sides of the side baffle 21, and the processing table is connected by the fixing plate 61. Two locking cylinders 22 are provided, the right baffle plate 26 is fixed on the fixed plate 61 on the rear side, and a locking plate 23 is provided on the piston rod extending from the locking cylinder 22. The sides of the two locking plates 23 close to each other are provided with arc grooves for locking the steel pipes between the side baffle plates 21, and the arc grooves pass through from left to right. The locking plate 23 is located on the lower side of the side baffle plates 21. The locking cylinder 22 can control the two locking plates 23 to approach each other, so as to clamp the steel pipes arranged up and down between the two side baffle plates 21 and at the bottom. After the steel pipes are clamped, they can be polished by the inner wall polishing assembly.

[0030] The inner wall polishing assembly includes a slide plate 31 slidably connected to the processing table 11 left and right, a polishing motor 32 is installed on the slide plate 31, and a polishing wheel 33 is installed at the end of the No. 1 output shaft extending from the polishing motor 32, the diameter of the polishing wheel 33 is adapted to the inner diameter of the steel pipe to be processed, that is, when the slide plate 31 moves to the left and the polishing motor 32 is energized, the polishing wheel 33 can enter the steel pipe clamped by the two locking plates 23 and polish the inner wall of the steel pipe. In order to realize the automatic left and right movement of the slide plate 31 and the polishing wheel 33, a translation motor 34 is provided on the processing table 11, and the No. 2 output shaft extending from the translation motor 34 is connected to a threaded shaft threadedly connected to the slide plate 31.

[0031] The dust removal assembly includes a vacuum cleaner (not shown in the figure), the vacuum port in the vacuum cleaner is connected to a vacuum tube 42, a slide groove 43 is provided in the upper side surface of the processing table 11, and a dust suction plate 44 connected to the vacuum tube 42 is slidably connected to the slide groove 43 for left and right movement, a rectangular groove for accommodating the vacuum plate 44 is provided in the left baffle plate 62, and a push-pull cylinder 45 for controlling the left and right positions of the vacuum plate 44 is provided on the processing table 11, specifically, the push-pull cylinder 45 is fixed on the left baffle plate 62, and when the steel pipe is clamped by the locking plate 23, the push-pull cylinder 45 can control the vacuum plate 44 to the right and sleeve on the left end of the clamped steel pipe, and at this time, the vacuum tube 42 is connected to the steel pipe.

[0032] In order to enable automatic discharge of the steel pipe after the inner wall is polished, a discharge mechanism is also included, which includes a discharge port 51 arranged on the upper side of the processing table 11, and the discharge port 51 passes through the processing table 11 outwardly, and the discharge port 51 is offset front and back from the side baffle 21.

After the inner wall of the steel pipe is polished, the two locking plates 23 move forward together. When the steel pipe clamped by the locking plates 23 is placed on the upper side of the discharge port 51, the locking plate 23 located at the front side moves forward again so that the polished steel pipe can fall into the discharge port 51 and be discharged. After that, the two locking plates 23 move backward together until they are reset to clamp the next steel pipe.

[0034] In the above process, the steel pipe located between the side baffles 21 will abut against the upper side of the locking plate 23 and will not fall. When the two locking plates 23 are reset, the steel pipe located in the side baffles 21 will fall and fall between the two locking plates 23. At this time, the two locking plates 23 can continue to approach each other to clamp the next steel pipe.

[0035] In the second embodiment of the discharge mechanism, there is no requirement for the front and rear width of the locking plate 23, and a blocker is installed on the side baffle 21, and the pop-up plate in the blocker extends between the two side baffles 21, and each side baffle 21 is provided with two blockers distributed on the left and right. In this embodiment, when the locking plates 23 jointly push the clamped steel pipe forward to be placed in the discharge port 51, the blocker can block the steel pipe between the side baffles 21 and prevent it from falling prematurely.

[0036] In order to facilitate the staff to stack the steel pipes between the side baffles 21, an obliquely arranged expansion plate 24 is installed at the upper end of each side baffle 21.

[0037] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
