[0028] Understandably, referring to Figures 1 to 4The square tube cutting machine of this utility model includes a frame 100, a clamping mechanism 200, and a conveying mechanism 300. The frame 100 is equipped with a laser assembly 110, which is used to cut square tubes. The clamping mechanism 200 includes a turntable 210, a first driving member 220, and four clamping assemblies 230. The turntable 210 is rotatably connected to the frame 100. The first driving member 220 is used to drive the turntable 210 to rotate on the frame 100. The turntable 210 has a rectangular hole 211. The four clamping assemblies 230 are evenly arranged circumferentially along the rectangular hole 211. Each clamping assembly 230 includes a second... The second drive component 231, the movable block 232, and the roller 233 are connected to the movable end of the second drive component 231. The roller 233 is rotatably connected to the movable block 232. The second drive component 231 is used to drive the movable block 232 to move towards the rectangular hole 211. The conveying mechanism 300 includes a moving component 310 and two rolling components 320. The two rolling components 320 are arranged opposite to each other on the rectangular hole 211. The moving component 310 is used to drive the two rolling components 320 to move closer to each other to clamp the square tube. The rolling components 320 are used to drive the square tube to move along the axial direction of the turntable 210.

[0029] The laser assembly 110 is mounted on the frame 100, and the turntable 210 is rotatably connected to the frame 100. The turntable 210 has a rectangular hole 211, and four clamping assemblies 230 are evenly spaced around the rectangular hole 211. The square tube passes through the rectangular hole 211. The second driving member 231 drives the movable block 232 to move closer to the rectangular hole 211 so that the roller 233 can abut against the square tube. The four rollers 233 cooperate to position the square tube in the rectangular hole 211, so that the position of the square tube can be kept stable. Then the first driving member 220 drives the turntable 210 to rotate to adjust the position of the laser assembly 110 cutting the square tube and improve the cutting accuracy. In addition, two rolling components 320 are arranged opposite each other on the rectangular hole 211. The moving component 310 can drive the two rolling components 320 to move closer to each other so that the two rolling components 320 can clamp the square tube. The rolling components 320 can drive the square tube to move along the axial direction of the turntable 210, so that the square tube can slide on the roller 233. This makes the square tube transport flexible and stable, reduces the positioning error of the square tube, and can replace manual adjustment of the position of the square tube, realize continuous processing of the square tube cutting machine, and improve production efficiency.

[0030] The four clamping components 230 are arranged around the rectangular hole 211, so that the four clamping components 230 can cooperate to position the square tube in the rectangular hole 211, thereby improving the positioning accuracy of the square tube.

[0031] It should be noted that the first driving component 220 can be an electric motor, pneumatic motor, etc., and the second driving component 231 can be a linear cylinder, electric actuator, linear slide module, etc., without limitation.

[0032] Understandably, referring to Figure 1 , Figure 2 and Figure 4 The moving component 310 includes a fixed base 311, a guide rod 312, two springs 313 and two sliders 314. The fixed base 311 is fixedly connected to the turntable 210, the guide rod 312 is fixedly connected to the fixed base 311, the sliders 314 are slidably connected to the guide rod 312, the springs 313 are arranged between the fixed base 311 and the sliders 314, and the springs 313 are used to drive the two sliders 314 to move closer to each other. Two rolling components 320 are respectively connected to the two sliders 314. The fixed base 311 is fixedly connected to the turntable 210, the guide rod 312 is fixedly connected to the fixed base 311, and the slider 314 is slidably connected to the guide rod 312. One end of the spring 313 abuts against the fixed base 311, and the other end abuts against the slider 314 to drive the two sliders 314 to move closer to each other. By setting two rolling components 320 respectively on the two sliders 314, the two rolling components 320 can move closer to each other to clamp the square tube, thereby adapting to square tubes of different sizes, improving the stability and flexibility of clamping, and facilitating the movement of the square tube driven by the rolling components 320.

[0033] The guide rod 312 has a fixed connection to a limiting part 316 at its center. The diameter of the limiting part 316 is larger than the diameter of the guide rod 312. The spring 313 can drive the slider 314 to abut against the limiting part 316. When the square tube is pushed between the two rolling components 320, the square tube can drive the two rolling components 320 to move away from each other, causing both sliders 314 to separate from the limiting part 316 and compress the spring 313. This allows the square tube to be clamped between the two rolling components 320 by the elastic force of the spring 313, preventing the square tube from shifting or being damaged due to uneven force during transportation and improving the transportation stability of the square tube.

[0034] Furthermore, the number of guide rods 312 can be set to multiple, and the multiple guide rods 312 are arranged in parallel at intervals. The spring 313 can be sleeved on the guide rod 312 to stabilize the position of the spring 313, reduce the positional displacement of the spring 313, and improve the stability of use.

[0035] Specifically, refer to Figure 1 and Figure 2The slider 314 is provided with a guide portion 315, which is inclined. The two sliders 314 are symmetrically arranged so that the distance between the two guide portions 315 gradually increases in the direction away from the fixed base 311. The guide portions 315 are provided on the sliders 314. By symmetrically arranging the two sliders 314, the distance between the two guide portions 315 gradually increases in the direction away from the fixed base 311, allowing the two guide portions 315 to form a conical guide space. This allows the sliders 314 to abut against the wall of the guide portion 315 when the square tube is inserted between the two sliders 314. This makes it easier to open the two sliders 314 and smoothly enter the rectangular hole 211, improving the accuracy and efficiency of square tube insertion, preventing the square tube from getting stuck at the end of the rectangular hole 211, and improving reliability.

[0036] Specifically, refer to Figure 1 , Figure 2 and Figure 4 The rolling assembly 320 includes a guide roller 321 and a third drive member 322. The guide roller 321 is rotatably connected to the slider 314, and the third drive member 322 is used to drive the guide roller 321 to rotate. The guide roller 321 is rotatably connected to the slider 314 and is connected to the output end of the third drive member 322. The third drive member 322 can drive the guide roller 321 to rotate, so that the guide roller 321 can abut against and push the square tube to move axially along the turntable 210.

[0037] By setting two rolling components 320 facing each other on the rectangular hole 211, the two guide rollers 321 cooperate to clamp the square tube, improving the stability and continuity of the square tube during the conveying process, and making the axial movement of the square tube accurate, thereby improving the cutting accuracy of the square tube and improving the production quality.

[0038] It should be noted that the third drive component 322 can be an electric motor, a pneumatic motor, etc., and is not limited here.

[0039] Understandably, referring to Figure 1The conveying mechanism 300 also includes multiple sets of support assemblies 330, which are spaced apart on the frame 100. Each support assembly 330 includes a support rod 331, a support roller 332, and a fourth driving member 333. The support rod 331 is rotatably connected to the frame 100, and the support roller 332 is rotatably connected to the support rod 331. The fourth driving member 333 drives the support rod 331 to rotate, thereby allowing the support roller 332 to support the square tube. The multiple sets of support assemblies 330 are spaced apart on the frame 100, and the support rod 331 is rotatably connected to the frame 100. The fourth driving member 333 can drive the support rod 331 to rotate on the frame 100, adjusting the position of the support roller 332. This allows for flexible adjustment of the position supporting the square tube, adapting to square tubes of different sizes and improving the versatility and adaptability of the square tube cutting machine. Furthermore, the multiple sets of support assemblies 330 can form multiple support points along the length of the square tube, reducing the bending of the square tube and improving conveying stability.

[0040] Specifically, refer to Figure 1 and Figure 5 The support roller 332 has a guide groove 336 on its side wall to accommodate the square tube. The guide groove 336 is arranged around the support roller 332, and its bottom wall is arc-shaped. By providing the guide groove 336 around the side wall of the support roller 332, the square tube can be supported in the guide groove 336, thus limiting the conveying direction of the square tube, reducing its positional deviation, and improving the stability of the conveying. By setting the bottom of the guide groove 336 to be arc-shaped, the square tube can rotate smoothly in the guide groove 336 when the turntable 210 drives it to rotate, reducing the collision damage between the square tube and the guide groove 336 and improving the conveying stability of the square tube.

[0041] Specifically, refer to Figure 1 The fourth driving component 333 includes a linear cylinder 334 and a sliding sleeve 335. The fixed end of the linear cylinder 334 is hinged to the frame 100, and the movable end of the linear cylinder 334 is hinged to the sliding sleeve 335. The sliding sleeve 335 is slidably connected to the support rod 331. By setting the sliding sleeve 335 to be slidably connected to the support rod 331, when the linear cylinder 334 drives the sliding sleeve 335 to slide on the support rod 331, the sliding sleeve 335 can drive the support rod 331 to rotate on the frame 100. This facilitates the adjustment of the position of the support roller 332. Furthermore, the cooperation of the linear cylinder 334 and the sliding sleeve 335 improves the supporting force of the support rod 331 and enables precise adjustment of the position and angle of the support roller 332, thereby improving the reliability of the support assembly 330.

[0042] Understandably, referring to Figure 1 and Figure 3The first driving component 220 includes a motor 221, a first gear 222, and a second gear 223. The first gear 222 is connected to the output end of the motor 221, and the second gear 223 is fixedly connected to the turntable 210. The first gear 222 and the second gear 223 mesh. Both the first gear 222 and the second gear 223 are rotatably connected to the frame 100. The first gear 222 is connected to the output end of the motor 221, and the second gear 223 is fixedly connected to the turntable 210. By setting the first gear 222 and the second gear 223 to mesh, when the motor 221 drives the first gear 222 to rotate, the second gear 223 can drive the turntable 210 to rotate, so that the turntable 210 can rotate at a stable speed and angle. This improves the rotation accuracy of the square tube, facilitates the laser assembly 110 to cut the square tube, improves the cutting accuracy of the square tube, and improves the reliability of the square tube cutting machine.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
