When the two support assemblies 20 move closer to or farther away from each other, the two second motors 13 always drive the two support assemblies 20 to rotate, and the two support assemblies 20 are used to support the workpiece, and the workpiece is in contact with the grinding roller 12. A guide plate 14 is obliquely arranged on one side of the lower end of the feeding platform 11, and the upper end of the guide plate 14 is connected to the lower end of the feeding platform 11, and a collection box 15 is arranged below the lower end of the guide plate 14.

[0043] A plurality of steel pipes are placed in the material holding box 10, and the steel pipes move from the discharge port 102 to the feeding platform 11, and the material control component 50 makes the steel pipes slide one by one between the two support components 20, and the driving component 30 drives the two support components 20 to extend from the two ends of the workpiece to the inside of the steel pipe. Subsequently, the two support components 20 support the steel pipe, and the two second motors 13 drive the steel pipe to rotate through the two support components 20. At the same time, the grinding roller 12 rotates under the drive of the first motor 121, so as to grind the steel pipe. After grinding, the two support components 20 are driven by the driving component 30 to separate from the inside of the steel pipe, and the lifting component 40 drives the grinding roller 12 to rise until the polished steel pipe enters the collecting box 15 from the lower end of the feeding platform 11 and the guide plate 14, which can improve the degree of automation, carry out large-scale production and assembly line operation, and improve the production capacity and economic benefits of the enterprise.

[0044] As an embodiment, in conjunction with the attached Figure 2 It can be seen that the support assembly 20 includes a first turntable 21 arranged on the side of the feeding platform 11, the first side of the first turntable 21 away from the feeding platform 11 is connected to the power output end of the second motor 13, the second motor 13 is connected to the driving assembly 30, and a first rotating shaft 22 is arranged on the second side of the first turntable 21. The first rotating shaft 22 is parallel to the feeding platform 11, and the first rotating shaft 22 rotates under the drive of the third motor 221; two support plates 25 are arranged in parallel on both sides of the first rotating shaft 22, and are respectively connected to the first rotating shaft 22 through two connecting assemblies. When the first rotating shaft 22 rotates, the two connecting assemblies drive the two support plates 25 to approach or move away from the first rotating shaft 22. The connecting assembly includes two first sliders 23 which are respectively threadedly connected to and penetrate two threaded sections with opposite rotation directions on the first rotating shaft 22; two groups of transmission parts are respectively connected to two support plates 25 through the two first sliders 23, and each group of transmission parts is composed of two first connecting rods 24, the first ends of the two first connecting rods 24 are respectively hinged to the two first sliders 23, and the second ends of the two first connecting rods 24 are respectively hinged to the support plates 25.

[0045] The driving assembly 30 drives the two supporting assemblies 20 to extend into the two ends of the steel pipe through the two second motors 13, and then the third motor 221 drives the first rotating shaft 22 to rotate, and the first rotating shaft 22 drives the two first sliders 23 to move away from or approach each other, and the two first sliders 23 drive the supporting plate 25 to move closer to or away from the first rotating shaft 22 through the first connecting rod 24, so that the supporting plate 25 hits or separates from the inner wall of the steel pipe. When the support plate 25 hits the inner wall of the steel pipe, the second motor 13 drives the first turntable 21 to rotate, and the first turntable 21 drives the third motor 221 and the supporting assembly 20 to rotate, so that the support plate 25 drives the steel pipe to rotate, so that the grinding roller 12 grinds the outer wall of the steel pipe.

[0046] Specifically, the third motor 221 is a forward and reverse motor.

[0047] As an embodiment, in conjunction with the attached Figure 3 It can be seen that the driving assembly 30 includes two movable plates 31 which are parallel and slidably arranged below the feeding table 11.

The first gear 34 rotates under the drive of the fourth motor 35.

[0048] The fifth motor 421 drives the first gear 34 to rotate, and the first gear 34 drives the two movable plates 31 to move relative to or away from each other through the two first racks 33. The two movable plates 31 drive the two second motors 13 to move closer to or away from each other through the two support plates 32. The two motors drive the two supporting assemblies 20 to move closer to or away from each other, which can effectively and conveniently make the steel pipe slide to the grinding roller 12, and can also effectively support the workpiece, thereby driving the workpiece to rotate.

[0049] Specifically, the fourth motor 35 is a forward and reverse motor.

[0050] As an embodiment, in conjunction with the attached Figure 4 It can be seen that the lifting assembly 40 includes two second sliders 41 respectively connected to the rotating shafts at both ends of the grinding roller 12; the first screw 42 is threadedly connected to and penetrates one of the second sliders 41, and rotates under the drive of the fifth motor 421; the first optical axis 43 is arranged parallel to the first screw 42, and is slidably connected to and penetrates the other second slider 41.

[0051] The fifth motor 421 drives the first screw 42 to rotate, and the first screw 42 drives the grinding roller 12 to rise and fall through the second slider 41. The first optical axis 43 can maintain the balance of the grinding roller 12 when it is raised and lowered, which can effectively facilitate the polished steel pipe to enter the collection box 15 from the lower end of the feeding table 11 and the guide plate 14.

[0052] Specifically, the fifth motor 421 is a forward and reverse motor.

[0053] Specifically, the first screw 42 is perpendicular to the feeding platform 11 .

[0054] As an embodiment, in conjunction with the attached Figure 5It can be seen that the material control component 50 includes a U-shaped material stopper 51, the middle of which is rotatably arranged on one side of the feeding platform 11, a first cantilever 52 is arranged above the feeding platform 11, a first end of the first cantilever 52 is connected to the first side of the material stopper 51, a first material stopper plate 521 arranged at the second end corresponds to the through groove 54 on the bottom surface of the feeding platform 11, a second cantilever 53 is arranged below the feeding platform 11, a first end of the second cantilever 53 is connected to the second side of the material stopper 51, and a second material stopper plate 531 arranged at the second end corresponds to the through groove 54 on the bottom surface of the feeding platform 11; the spacing between the first material stopper plate 521 and the second material stopper plate 531 is adapted to the diameter of the workpiece, a cam 55 is arranged below the feeding platform 11, and rotates under the drive of the sixth motor 56, and the circumferential curved surface of the cam 55 abuts against the side of the material stopper 51, and when the cam 55 rotates, it can drive the material stopper 51 to swing with its middle part as the rotating axis.

[0055] When the sixth motor 56 drives the cam 55 to rotate, so that the cam 55 drives the material blocking rack 51 to descend, a workpiece will slide between the two cantilevers; when the material blocking rack 51 rises, a workpiece will slide between the two support assemblies 20, and at the same time, due to the rise of the second cantilever 53, the remaining workpieces are blocked on the feeding table 11 between the material control assembly 50 and the material storage box 10, preventing the remaining workpieces from sliding off the feeding table 11 between the material control assembly 50 and the material storage box 10. The through groove 54 provided on the bottom surface of the feeding table 11 facilitates the second cantilever 53 to pass upward through the feeding table 11 to block the workpiece. When the material blocking rack 51 completes a lifting, it can make a workpiece slide between the two support assemblies 20, so as to achieve the purpose of interval material unloading. The whole mechanism has a compact structure and a good material control effect.

[0056] As an embodiment, in conjunction with the attached Figure 1 It can be seen that a discharge plate 103 inclined toward the discharge port 102 is provided in the material holding box 10, so that the material can be discharged conveniently.
