[0035] The preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] like Figures 1 to 17 As shown, this embodiment provides a polishing detection device based on automatic feeding and cutting of steel pipes, comprising: a steel pipe feeding component 1, a cutting component 2, a handling robot component 3, a polishing component 4, a good product conveyor belt 5 and a detection component 6, wherein the steel pipe feeding component 1 is arranged at one end of the cutting component 2, the polishing component 4 is arranged at the other end of the cutting component 2, and the polishing component 4 is connected to the good product conveyor belt 5 and the detection component 6 through the handling robot component 3; the steel pipe feeding component 1 is used to separate and feed the steel pipe raw materials 12 one by one to convey them to the cutting component 2; through the The cutting component 2 cuts the steel pipe raw material 12 according to the preset length, and sends the cut steel pipe to the polishing component 4 for polishing; the polished steel pipe is transported to the detection component 6 by the handling robot component 3. When the steel pipe is detected to be qualified, it is transported to the good product conveyor belt 5 by the handling robot component 3. When the steel pipe is detected to be unqualified, it is transported to the unloading chute 68 of the detection component 6 by the handling robot component 3; the preset length refers to the pre-set cutting length for the steel pipe raw material 12, which can be adjusted according to actual conditions and needs.

[0037] Among them, the steel pipe feeding assembly 1 includes a feeding frame 11, a pushing structure 13, a material dividing cylinder 14 and a lifting plate 15, the lifting plate 15 is tilted and movably arranged on one side of the feeding frame 11 by the material dividing cylinder 14, and a material trough 151 is arranged on the top of the lifting plate 15, the position of the material trough 151 corresponds to the feeding position of the cutting assembly 2, and the pushing structure 13 is movably arranged next to the material trough 151; the feeding process of the steel pipe feeding assembly 1 is as follows: first, the lifting plate 15 is driven to move tilted downward by the material dividing cylinder 14, so that a single steel pipe raw material 12 enters the material trough 151; then, the lifting plate 15 is driven to move tilted upward by the material dividing cylinder 14, and the steel pipe raw material 12 in the material trough 151 is pushed into the cutting assembly 2 through the pushing structure 13 toward the direction of the cutting assembly 2, so as to realize the separation and feeding of the steel pipe raw materials 12 one by one.

[0038] It is worth noting that, in the face of a large number of long steel pipes piled up in the actual application environment, if the feeding device of the prior art is used, it cannot meet the actual application requirements of separating and feeding a large number of steel pipe raw materials 12 piled up one by one. In contrast, this embodiment designs the steel pipe feeding assembly 1 based on the optimization design of the overall structure and for the actual application environment of a large number of long steel pipes piled up.

[0039] The feeding frame 11 in the steel pipe feeding assembly 1 is used to install the pushing structure 13, the material dividing cylinder 14 and the ejecting plate 15, and is used to carry and stack a large amount of steel pipe raw materials 12. The pushing structure 13 refers to a structure used to push the steel pipe raw materials 12 in the material trough 151 into the cutting assembly 2. The material dividing cylinder 14 refers to a driving structure arranged at the bottom of the ejecting plate 15, thereby driving the ejecting plate 15 to move upward and downward. Figure 2 As shown, the ejector plate 15 is tilted and movably arranged on one side of the loading frame 11 through the material separation cylinder 14, that is, the ejector plate 15 is tilted and inserted on one side of the loading frame 11, and the other side of the loading frame 11 is used to stack the steel pipe raw materials 12. When the ejector plate 15 moves downward to the side or below the steel pipe raw materials 12, the single material can be separated through the material trough 151. Preferably, the side wall of the loading frame 11 is provided with an inclined groove to provide a guide rail for the movement of the ejector plate 15. Figure 3 and Figure 4As shown, a material trough 151 is provided on the top of the ejector plate 15, the position of the material trough 151 corresponds to the feeding position of the cutting component 2, and the size of the material trough 151 corresponds to the size of a single steel pipe raw material 12, and the pushing structure 13 is movably arranged next to the material trough 151; the loading process of the steel pipe loading component 1 is as follows: first, the ejector plate 15 is driven to move obliquely downward by the material dividing cylinder 14, so that a single steel pipe raw material 12 enters the material trough 151; then, the ejector plate 15 is driven to move obliquely upward by the material dividing cylinder 14, and when it moves to the corresponding position of the cutting component 2, the steel pipe raw material 12 in the material trough 151 is pushed into the cutting component 2 in the direction of the polishing component 4 by the pushing structure 13, so as to realize the separation and loading of the steel pipe raw materials 12 one by one.

[0040] like Figure 2 As shown, the material distribution cylinder 14 in this embodiment is arranged at the bottom of the ejection plate 15, so as to utilize the bottom space of the ejection plate 15 to set the material distribution cylinder 14, and lower the center of gravity of the entire steel pipe feeding assembly 1, thereby ensuring the stability of the feeding process of the steel pipe feeding assembly 1. Preferably, the telescopic direction of the material distribution cylinder 14 is consistent with the tilting direction of the ejection plate 15. Then, the telescopic movement of the material distribution cylinder 14 can be directly controlled by using the telescopic movement of the ejection plate 15. More preferably, the tilting angle of the ejection plate 15 is 15°-35°, so as to avoid the angle being too small to ensure the feeding process of a single material, and to avoid the angle being too large to increase unnecessary driving force.

[0041] like Figure 5 As shown, the pushing structure 13 of this embodiment includes a pushing cylinder 131, a linear guide 132 and a pushing plate 133. The pushing plate 133 is movably arranged at one end of the material trough 151 away from the cutting component 2 through the pushing cylinder 131 and the linear guide 132. A pushing baffle 134 is arranged on the outer side of the pushing plate 133. The position of the pushing baffle 134 corresponds to the position of the material trough 151, and the size and shape of the pushing baffle 134 are matched with the size and shape of the material trough 151, so that it can move well in the material trough 151 to ensure that the steel pipe raw material 12 is pushed into place.

[0042] like Figure 6As shown, the cutting assembly 2 of this embodiment includes a cutting frame 21, a limiting feeding structure 22, a driven limiting structure 23, a cutting structure 24 and a material detection structure 25, wherein the limiting feeding structure 22 is arranged at one end of the cutting frame 21 close to the steel pipe feeding assembly 1, and the cutting structure 24 is arranged at one end of the limiting feeding structure 22 away from the steel pipe feeding assembly 1, and the two ends of the cutting structure 24 are both provided with the driven limiting structure 23, and the driven limiting structure 23 is away from the steel pipe feeding assembly 1. A material detection structure 25 is provided at one end; after the steel pipe is pushed into the limit feeding structure 22, the limit feeding structure 22 drives the steel pipe to pass through the driven limit structure 23 and the cutting structure 24 in sequence, until the sensor 253 of the material detection structure 25 detects the presence of material, and the cutting structure 24 starts to work and cuts the steel pipe; when the cutting structure 24 is reset and stopped, the limit feeding structure 22 continues to drive the steel pipe in the direction of the material detection structure 25, so as to push out the cut steel pipe. The difference between the limit feeding structure 22 and the driven limit structure 23 is that the limit feeding structure 22 is equipped with a corresponding driving structure to provide power for the transportation of the steel pipe raw material 12.

Above the motor 245, the cutting blade 249 is connected to the output shaft of the cutting motor 245; in the cutting process of the cutting structure 24, the cutting motor 245 is first started to make the cutting blade 249 rotate at high speed, and the cutting cylinder 248 drives the cutting motor 245 to move downward, and the upward force is generated by the compression of the cutting spring 242 to slow down the movement speed of the cutting cylinder 248 to achieve buffering, so that the cutting blade 249 can smoothly cut the steel pipe, and the overall cutting process is stable and reliable. When the cutting is completed, the cutting cylinder 248 is reset and the cutting motor 245 stops rotating.

[0044] like Figure 8As shown, the material detection structure 25 of this embodiment includes a detection bracket 251, a detection cylinder 252, a sensor 253 and a sensing baffle 254. The sensing baffle 254 is movably arranged in the detection bracket 251 through the detection cylinder 252, and is used to achieve a blocking effect on the steel pipe, so as to assist in the cutting of the steel pipe; the sensor 253 is arranged on the side of the detection bracket 251 close to the driven limiting structure 23; when the sensor 253 detects the steel pipe, the sensing baffle 254 is pushed downward by the detection cylinder 252, so that the sensing baffle 254 is lowered into place to prevent the steel pipe from continuing to move, thereby achieving a limiting effect on the steel pipe in the forward direction, which is convenient for the cutting structure 24 to cut the steel pipe; until the steel pipe is cut, the sensing baffle 254 is pulled upward by the detection cylinder 252 to remove the blocking effect, so that the steel pipe can continue to move forward, providing a basis for entering the next cutting operation.

When the cut steel pipe enters the polishing bracket 45, it is brought to the polishing position by the polishing sliding cylinder 46. The polishing position refers to the contact position between the polishing component 4 and the steel pipe. Then, the two ends of the cut steel pipe are supported by the ejector mechanism 44. After the cut steel pipe is supported, the polishing mechanism 43 is used to polish the steel pipe, and at the same time, the sliding table 42 cooperates with the sliding to polish the cut steel pipe.

When the steel pipe is placed on the polishing bracket 45, the steel pipe is supported by the tangent surfaces of the two polishing bearings 454 and the steel pipe. When the steel pipe rotates on the polishing bearings 454, the polishing bearings 454 will also rotate with the steel pipe to reduce the wear marks on the surface of the steel pipe and ensure the actual polishing effect.

[0049] like Fig.16 As shown, the steel pipe described in this embodiment is transported to the designated position by the transport manipulator assembly 3, that is, the detection position where the detection assembly 6 is located. The detection assembly 6 includes a detection frame 61, a detection ejector mechanism 62, a detection slide 63, a detection camera 64, a detection rotation mechanism 65, a detection linear guide 66, a detection sliding cylinder 67 and a discharge chute 68. The steel pipe is clamped by the detection rotation mechanism 65, and the detection ejector mechanism 62 holds the other end of the steel pipe. When the transport manipulator assembly 3 leaves the designated position, the detection sliding cylinder 67 delivers the steel pipe to the detection position. The detection slide 63 drives the detection camera 64 to scan and take pictures of the steel pipe above the steel pipe. When the detection camera 64 completes the scanning and taking pictures of one side of the steel pipe, the detection rotation mechanism 65 drives the steel pipe to rotate 180°, and then the detection slide 63 and the detection camera 64 scan and take pictures of the other side of the steel pipe. By comparing the photos taken twice with the sample photos, it is judged whether there are sand holes and deep scratches on the surface of the steel pipe. After the inspection is completed, the steel pipe is brought back to the initial position by the inspection sliding cylinder 67, waiting for the handling robot assembly 3 to pick up the material. Fig.17 As shown, the detection rotating mechanism 65 includes a detection mounting frame 651, a detection rotating cylinder 652, a detection pneumatic clamp mounting plate 653 and a detection pneumatic clamp 654. When the steel pipe reaches a preset detection position, the detection pneumatic clamp 654 clamps the steel pipe. When the steel pipe needs to be flipped, the detection rotating cylinder 652 rotates, and the detection pneumatic clamp 654 installed on the detection rotating cylinder 652 will also flip accordingly, thereby driving the steel pipe to flip.

[0050] In summary, the present embodiment includes a steel pipe feeding component 1, a cutting component 2, a handling robot component 3, a polishing component 4, a good product conveyor belt 5 and a detection component 6 that work in coordination. The steel pipe feeding component 1 can separate and feed the steel pipe raw material 12 one by one, and then transport it to the cutting component 2, and cut it according to a preset length, and then send the cut steel pipe to the polishing component 4 for polishing, and the polished steel pipe is transported to the detection component 6 by the handling robot component 3. When the steel pipe is detected as qualified, it is transported to the good product conveyor belt 5 by the handling robot component 3. When the steel pipe is detected as unqualified, it is transported to the discharge trough 68 of the detection component 6 by the handling robot component 3. Therefore, the present embodiment can realize automatic feeding and cutting of the accumulated long steel pipes through automated equipment integration and optimized design, and coordinately realize subsequent processes such as polishing and detection, effectively improving the automation level of steel pipe processing and production, and ensuring product consistency and production yield, and effectively reducing labor costs.
