[0002] The rapid development of the modern metalworking industry has led to higher requirements for precision, efficiency, and cost in tube processing. Currently, a wide variety of laser tube cutting machines are available on the market, including dual-chuck and side-mounted chuck configurations. Single-chuck cut-off laser tube cutting machines are particularly popular among small and medium-sized enterprises due to their simple structure and easy maintenance. However, existing single-chuck cut-off laser tube cutting machines typically clamp tubes to fixed dimensions, making them incapable of handling tubes of varying sizes and specifications. This poor adaptability impacts production efficiency. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The single-chuck truncation laser tube cutting machine in the prior art mostly has a fixed clamping size for tubes, cannot transport tubes of different specifications and sizes, has poor applicability, and easily affects production efficiency. The following describes a clamping device for a single-chuck truncation laser tube cutting machine provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0023] Example 1:

[0024] In order to optimize the design and control strategy of the clamping and conveying device and ensure the stability of the pipe body 1 during conveying, Figure 1 、 Figure 2 and Figure 3 As shown, a clamping device for a single-chuck truncation-type laser tube cutting machine is proposed. A tube body 1 is provided for conveying and transmitting. A supporting mechanism 2 is provided at the bottom of the tube body 1. Multiple mechanisms are connected and fixed by the supporting mechanism 2. A clamping mechanism 3 is provided on the top of the supporting mechanism 2. The clamping mechanism 3 is used to fix and convey tube bodies 1 of different specifications. A correction mechanism 4 is provided on one side of the clamping mechanism 3. The correction mechanism 4 is used to further correct the tube body 1.

[0025] In order to enhance the adaptability of the device and thus meet the diversified production needs of pipes of different sizes and shapes, a clamping mechanism 3 is proposed, which includes a left slide 301 and a right slide 302. A clamping cylinder is installed on one side of the right slide 302. A left guide rail 303 and a right guide rail 304 are fixed to the mounting plate 201 by bolts. A left rack 307 and a right rack 308 are installed on the top of the left slide 301 and the right slide 302 respectively. Two sliders 305 are fixedly connected to the bottom of the left slide 301 and the right slide 302. A cylindrical gear 306 is fixedly connected to the mounting plate 201. The left rack 303 and the right rack 304 are fixed to the mounting plate 201. 07 and the right rack 308 are meshed with the cylindrical gear 306, and the left skateboard 301 and the right skateboard 302 are respectively connected to the left rubber-coated roller wheel group 309 and the right rubber-coated roller wheel group 310. The bottom of the left skateboard 301 and the right skateboard 302 are respectively installed with the left motor reducer group 311 and the right motor reducer group 312. The drive shafts of the left motor reducer group 311 and the right motor reducer group 312 are both installed with sprocket chain transmission groups 313. Each chain in the two sprocket chain transmission groups 313 is installed with a chain group preload wheel 314. By adjusting the left motor reducer group 311 and the motor reducer group 312, the chain preload wheel 314 is tightened. The coordinated control of the right speed reducer unit 312 can realize pipe transportation. When the pipe falls into the clamping device, the right slide 302 is pushed by the clamping cylinder to slide forward along the left guide rail 303 and the right guide rail 304, and at the same time drive the right rack 308 to move. Since the right rack 308 and the left rack 307 are both engaged with the cylindrical gear 306, the left rack 307 will also move in the opposite direction synchronously with the right rack 308. Since the left rack 307 is fixed to the left slide 301, the right slide 302 and the left slide 301 move in the opposite direction synchronously along the left guide rail 303 and the right guide rail 304, and the left 308 is moved by the rubberized roller group. 9 moves synchronously with the right rubber-coated roller wheel group 310 to the center, thereby clamping the pipe body 1 in the center and improving the precision. The left rubber-coated roller wheel group 309 and the right rubber-coated roller wheel group 310 are driven to rotate by the left motor reducer group 311 and the right motor reducer group 312. The left rubber-coated roller wheel group 309 and the right rubber-coated roller wheel group 310 are driven to rotate by the sprocket chain transmission group 313. The left rubber-coated roller wheel group 309 and the right rubber-coated roller wheel group 310 are synchronously rotated in opposite directions by the left motor reducer group 311 and the right motor reducer group 312, driving the pipe to be fed forward, thereby improving the conveying precision and efficiency of the device.

[0026] Since the contact positions between all rollers in the left rubber-coated roller group 309 and the right rubber-coated roller group 310 and the pipe are concave structures, the clamping effect can be effectively maintained, the applicability of the clamping device is increased, and it can also be beneficial to the vertical centering and correction of the clamped pipe to a certain extent.

[0027] Example 2:

[0028] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the problem in the prior art that the clamping size of the pipe by the single-chuck truncation laser pipe cutting machine is mostly fixed, the applicability is poor, and the pipes of different specifications and sizes cannot be transported, thereby affecting production efficiency. However, when the pipe body 1 is transported to the final position, in order to ensure its stability, it needs to be further corrected.

[0029] In order to ensure the stability of the overall transportation of the pipe body 1, combined with Figure 1 and Figure 4 As shown, a correction mechanism 4 is proposed, which fixes a connecting plate 401 on the receiving mounting plate 201, and symmetrically installs two correction cylinders 402 and correction feeding rollers 403 on the connecting plate 401. The two correction feeding rollers 403 are symmetrical in the upper and lower directions relative to the final center position of the pipe body 1. When the pipe is transported to the correction position, the two correction cylinders 402 synchronously drive the corresponding correction feeding rollers 403 to clamp the pipe body 1, which can not only ensure that the pipe is centered in the upper and lower directions, but also effectively support and assist in transporting the pipe.

[0030] In order to connect and support multiple mechanisms, a supporting mechanism 2 is proposed. By installing a receiving mounting plate 201, the top of the receiving mounting plate 201 is fixedly connected with a left guide shield 202 and a right guide shield 203. The tops of the left guide shield 202 and the right guide shield 203 are symmetrically inclined at a certain downward angle. When the pipe body 1 is sent to the upper position of this device, the pipe body 1 falls from the top of the device, and the left guide shield 202 and the right guide shield 203 will guide the pipe body 1 and introduce the pipe body 1 into the clamping mechanism 3.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
