[0002] In the pipe processing and manufacturing industry, such as automotive parts production, aerospace pipe processing, and building decoration pipe manufacturing, laser cutting machines have become important equipment for pipe cutting due to their advantages of high precision, high speed, and non-contact processing. They are often required to cut pipes of different diameters. In actual production, due to the variety of product specifications, the same batch of production tasks may involve the cutting of pipes of multiple diameters.

[0003] In actual production, traditional laser cutting machine fixtures are insufficient to meet the demand for efficient and stable clamping of pipes of different diameters. When faced with cutting tasks involving multiple pipe diameters, fixtures often need to be changed frequently. The traditional fixture replacement process is cumbersome, requiring operators to manually disassemble and install different specifications of fixtures, which is time-consuming and greatly increases downtime caused by fixture replacement. When the pipe diameter changes during production, operators need to spend a lot of time and effort to adjust the fixtures. Furthermore, the positioning adjustment of traditional screw-locking fixtures requires a high level of professional skills and experience from the operators, making precise positioning during fixture replacement cumbersome and difficult. Therefore, a new laser cutting machine fixture is needed to solve the problems existing in the current technology. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4 This utility model provides a laser cutting machine fixture, comprising:

[0029] Support frame 1 is fixed on the machine base of laser cutting machine tool 2 and is used to support the fixture;

[0030] A switching mechanism 3 is located at one end of the clamp and is used to switch between clamps of different pipe diameters. The switching mechanism 3 includes an adjusting seat 9, which is fixed to one side surface of the support frame 1. An adjusting arm 10 is movably connected inside the adjusting seat 9. The first clamp 4, the second clamp 5, and the third clamp 6 are respectively fixed on the corresponding adjusting arms 10. An adjusting groove 12 is provided on the inner bottom wall of the adjusting seat 9. An adjusting slide column 11 is slidably connected in the adjusting groove 12 of the adjusting seat 9. The upper end of the adjusting slide column 11, which extends out of the adjusting groove 12, is fixed to the bottom of the adjusting arm 10. In the positioning stage before laser cutting of different pipe diameters, when the pipe diameter to be processed does not match the first clamp 4 of the current station, the first clamp 4 is adjusted to another position that does not interfere with the switching of the second clamp 5 by adjusting the adjusting slide column 11 at the bottom of the adjusting arm 10 along the adjusting groove 12 of the adjusting seat 9. The second clamp 5 that is adapted to the current pipe diameter is switched to the current station, ensuring that a pair of second clamps 5 remain stable during the cutting process. Pre-assembling clamps that are adapted to various pipe diameter specifications can save the waiting time for spare parts and meet the firm clamping requirements when processing pipe products of different specifications.

[0031] The locking mechanism 8 is fixed to the upper part of the switching mechanism 3. The locking mechanism 8 is used to lock the fixture at the current workstation. The fixture includes a first fixture 4, a second fixture 5 and a third fixture 6. The first fixture 4 is set at the current workstation of the switching mechanism 3, the second fixture 5 is set on one side of the first fixture 4 and the third fixture 6 is set on the other side of the first fixture 4. After the adjusting arm 10 of the second fixture 5 moves into place, the positioning slide rod 15, under the action of the return spring 16, causes the positioning insert 17 to be engaged in the positioning groove 13 on the upper end face of the adjusting arm 10, thus completing the locking of the second fixture 5 at the current workstation.

[0032] The locking mechanism 8 includes a spring sleeve 14, which is fixed to the upper end face of the adjusting seat 9. A positioning slide rod 15 is slidably connected inside the spring sleeve 14. A positioning insert 17 is fixed to one end of the positioning slide rod 15 that extends out of the spring sleeve 14. A positioning groove 13 is provided on the upper end face of the adjusting arm 10. The positioning insert 17 is fitted into the positioning groove 13. A return spring 16 is sleeved on the part of the positioning slide rod 15 that extends into the spring sleeve 14. One end of the return spring 16 is fixed to the end plate of the positioning slide rod 15, and the other end of the return spring 16 is fixed to the inner end wall of the spring sleeve 14. Different specifications of clamps can be accurately switched to the current working position of the adjusting seat 9 by the adjusting arm 10. The locking mechanism 8 automatically locks and manually unlocks by overcoming the spring force, which can quickly realize the switching of clamps of different pipe diameters and specifications, greatly shortening the downtime caused by clamp replacement and significantly improving the production efficiency of pipe cutting.

[0033] It is worth noting that the inner arc walls of the first clamp 4, the second clamp 5, and the third clamp 6 are fixed with anti-slip pads 7; the anti-slip pads 7 on the inner arc walls of a pair of clamps increase friction and firmly clamp the pipe.

[0034] It is worth noting that a cylinder 18 is fixed on one side surface of the support frame 1, and the output end of the cylinder 18 is fixed on one side surface of the adjusting seat 9. When the cylinder 18 is started, the output end of the cylinder 18 pushes the adjusting seat 9, causing a pair of clamps to move closer to each other until the pipe is clamped and positioned.

[0035] In the pipe processing and manufacturing industry, such as automotive parts production, aerospace pipe fitting processing, and building decoration pipe manufacturing, laser cutting machines are often used to cut pipes of different diameters. In actual production, due to the variety of product specifications, the same batch of production tasks may involve the cutting of pipes of multiple diameters.

[0036] Based on the above application scenarios, this solution provides a laser cutting machine fixture with the following working process: Before use, the laser cutting machine fixture is installed and fixed on the machine table of the laser cutting machine tool 2 through the support frame 1. According to the pipe diameter specifications of the pipe to be processed, the first fixture 4, the second fixture 5 and the third fixture 6 adapted to different pipe diameters are pre-installed at the corresponding positions of the switching mechanism 3. The front of the switching mechanism 3 is the current working position of the fixture.

[0037] In the positioning stage before laser cutting of different pipe diameters, when the pipe diameter to be processed does not match the first fixture 4 at the current station, the end plate of the positioning slide rod 15 is slid upward along the adjustment port on the side of the spring sleeve 14, causing the positioning insert 17 to disengage from the adjustment arm 10 on the first fixture 4, thereby removing the locking restriction of the adjustment arm 10 of the first fixture 4. Subsequently, the first fixture 4 is adjusted to another position that does not interfere with the switching of the second fixture 5 by moving along the adjustment groove 12 of the adjustment seat 9 via the adjustment slide pin 11 at the bottom of the adjustment arm 10. Similarly... The second clamp 5, which is adapted to the current pipe diameter, is switched to the current work position. After the adjusting arm 10 of the second clamp 5 is moved into place, the positioning slide rod 15, under the action of the return spring 16, causes the positioning insert 17 to be engaged in the positioning groove 13 on the upper end face of the adjusting arm 10, thus locking the second clamp 5 at the current work position. This ensures that the pair of second clamps 5 remain stable during the cutting process. Pre-assembling clamps that are adapted to various pipe diameter specifications can save the waiting time for spare parts and meet the firm clamping requirements when processing pipe products of different specifications.

[0038] When clamping the pipe, the pipe to be processed is placed in the switched fixture. At this time, the bottom of the pipe is supported on the table of the laser cutting machine tool 2. Then, the cylinder 18 is started. The output end of the cylinder 18 pushes the adjusting seat 9, which drives a pair of fixtures to move closer to each other. The anti-slip pads 7 on the inner arc walls of the pair of fixtures increase the friction and firmly clamp the pipe. Finally, the laser cutting machine is started to cut the pipe.

[0039] After the pipe is securely clamped on the worktable, the positioning system of the machine tool is used to precisely calibrate the position of the pipe to ensure that the laser cutting head can accurately align with the cutting starting point. The laser generator produces a high-energy laser beam, which is focused onto the surface of the pipe through the optical transmission system, causing the pipe material to rapidly absorb the laser energy and the temperature to rise sharply to the melting and boiling points, thereby achieving melting and vaporization for pipe cutting applications.

[0040] Different specifications of clamps can be accurately switched to the current position of the adjusting seat 9 by adjusting the support arm 10 along the adjusting seat 9, and automatically locked by the spring force of the locking mechanism 8 and unlocked by manually overcoming the spring force. This can quickly realize the switching of clamps of different pipe diameters, greatly shorten the downtime caused by clamp replacement, and significantly improve the production efficiency of pipe cutting.
