[0002] Laser cutting is a technique that uses a high-power-density laser beam to irradiate the material being cut, rapidly heating it to its vaporization temperature and causing it to evaporate and form a hole. As the beam moves across the material, the hole continuously forms a narrow kerf, thus completing the cutting of the material. In summary, the existing technology has the following problems: Laser cutting technology is commonly used in the cutting of metal tubes. Laser cutting clamping fixtures are auxiliary tools specifically designed for laser cutting equipment to ensure that the metal tube does not move during the cutting process, thereby guaranteeing cutting accuracy and quality. Typically, clamping fixtures use bolts to adjust the clamping components to position the metal tube. Bolt adjustment is cumbersome, and the accuracy of bolt adjustment is easily affected by the skill level of the technician, leading to a decrease in clamping accuracy. Furthermore, bolt adjustment is time-consuming and inconvenient. However, existing laser cutting clamping fixtures lack components for more stable clamping of metal tubes. Therefore, this paper proposes a laser cutting clamping fixture to solve the above problems. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a clamping fixture for laser cutting, which has the advantage of providing more stable clamping for metal tubes during laser cutting. This solves the problem commonly encountered in existing laser cutting technology for cutting metal tubes. Laser cutting clamping fixtures are auxiliary tools specifically designed for laser cutting equipment to ensure that the metal tube does not move during the cutting process, thereby guaranteeing cutting accuracy and quality. Typically, clamping fixtures use bolts to adjust the clamping components to position the metal tube. Bolt adjustment is cumbersome, and the accuracy of bolt adjustment is easily affected by the skill level of the technician, leading to a decrease in clamping accuracy. Furthermore, bolt adjustment is time-consuming and inconvenient. However, existing clamping fixtures used in laser cutting lack components for more stable clamping of metal tubes.

[0004] This utility model is implemented as follows: a clamping fixture for laser cutting includes a clamping base and two adjusting frames. The top of the clamping base and the bottom of the adjusting frames are movably connected. A fixed clamping ring is fixedly connected to the front side of the adjusting frame. A movable clamping ring that cooperates with the fixed clamping ring is movably connected to the inner cavity of the adjusting frame. An adjusting shell is fixedly connected to the rear side of the movable clamping ring. An adjusting device is provided in the inner cavity of the adjusting shell.

[0005] In a preferred embodiment of this invention, the adjusting device includes two right-angled adjusting blocks. The side of each right-angled adjusting block near the adjusting frame penetrates the adjusting shell and extends to the outer side of the inner cavity of the adjusting shell. A spring is fixedly connected to the front side of each right-angled adjusting block, and the surface of the spring is fixedly connected to the inner cavity of the adjusting shell. A square outer shell is fixedly connected to the rear side of each right-angled adjusting block. A square inner rod is movably connected to the inner cavity of the square outer shell, and the surface of the square inner rod is movably connected to the inner cavity of the adjusting shell. By providing the adjusting device, when the height of the moving clamping ring needs to be adjusted according to the size of the metal tube, the adjusting device has an adjusting function on the position of the moving clamping ring.

[0006] In a preferred embodiment of this invention, a circular column is fixedly connected to each of the two adjustable right-angle blocks on opposite sides. The inner cavity of the adjusting shell is movably connected to two rotating frames that cooperate with the circular columns via a rotating shaft. The inner cavity of the rotating frame is movably connected to the surface of the circular column. By setting the circular column and the rotating frame, when the rotating frame rotates, it can generate a squeezing force on the circular column. The circular column subjected to the squeezing force can drive the adjusting right-angle blocks to move.

[0007] In a preferred embodiment of this invention, the inner cavity of the adjusting shell is movably connected to two compression control frames that cooperate with the rotating frame. The surface of the compression control frame contacts the surface of the rotating frame. The rear side of the compression control frame penetrates the adjusting shell and extends to the outer side of the inner cavity of the adjusting shell. The rear side of the adjusting shell is fixedly connected to a limiting frame that cooperates with the compression control frame. The surface of the limiting frame is movably connected to the inner cavity of the compression control frame. By setting the compression control frame and the limiting frame, pulling the compression control frame causes it to move along the surface of the limiting frame. The limiting frame restricts the movement of the compression control frame. When the compression control frame moves, it can generate a compressive force on the rotating frame.

[0008] As a preferred embodiment of this invention, the rear side of the adjustment frame is provided with a right-angle groove for use with the adjustment right-angle block. The surface of the adjustment right-angle block contacts the inner cavity of the right-angle groove. The number of right-angle grooves is several and they are evenly distributed on the rear side of the adjustment frame. By setting the right-angle groove, when the adjustment shell and the moving clamping ring move to the appropriate position, the squeezing control frame is released, and the restoring force generated by the spring returning to its shape will drive the adjustment right-angle block to be inserted into the inner cavity of the right-angle groove. The cooperation between the adjustment right-angle block and the right-angle groove has a limiting effect on the position of the adjustment shell and the moving clamping ring.

[0009] As a preferred embodiment of this utility model, the bottom of the adjustment frame is fixedly connected to a plug-in block, and the inside of the clamping base is provided with a plurality of plug-in slots that cooperate with the plug-in block. The surface of the plug-in block is movably connected to the inner cavity of the plug-in slot. By setting the plug-in block and the plug-in slot, when the plug-in block moves to the inner cavity of the plug-in slot, it can drive the movable clamping ring and the fixed clamping ring to move to the top of the clamping base. The cooperation of the plug-in block and the plug-in slot allows the movable clamping ring and the fixed clamping ring to be limited to an appropriate position according to the length of the metal tube.

[0010] As a preferred embodiment of this utility model, a baffle groove is provided on the left side of the clamping base, and a baffle is movably connected to the inner cavity of the baffle groove. The rear side of the baffle contacts the surface of the insertion block. By setting the baffle and the baffle groove, when the insertion block moves into the inner cavity of the insertion groove, the baffle is moved into the inner cavity of the baffle groove. When the rear side of the baffle contacts the surface of the insertion block, the baffle has a limiting effect on the position of the insertion block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model solves the problem of existing laser cutting technology commonly used in the cutting of metal tubes by setting up an adjustment device, adjusting right-angle blocks, springs, square outer shells and square inner rods in combination. Laser cutting clamping fixtures are auxiliary tools specifically used for laser cutting equipment to ensure that the metal tube does not move during the cutting process, thereby ensuring cutting accuracy and quality. Usually, clamping fixtures use bolts to adjust the clamping components to position the metal tube. Bolt adjustment is relatively cumbersome, and the accuracy of bolt adjustment is easily affected by the skill level of the technician, resulting in a decrease in clamping accuracy. Moreover, bolt adjustment is time-consuming and inconvenient. However, existing clamping fixtures used in laser cutting do not have components that provide more stable clamping for metal tubes.

[0013] 2. By setting an adjustment device, the two circular cylinders subjected to the extrusion force will move backward. When the circular cylinders move, they will drive the adjusting right-angle block to move backward. When the adjusting right-angle block moves, it will drive the square outer shell to move along the surface of the square inner rod. At the same time, the force generated when the adjusting right-angle block moves causes the spring to undergo elastic deformation. The restoring force generated by the spring returning to its shape will drive the adjusting right-angle block to be inserted into the inner cavity of the right-angle groove. The adjustment device has the function of adjusting the position of the moving clamping ring. Attached Figure Description

[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown in the figure, the present invention provides a clamping fixture for laser cutting, including a clamping base 1 and two adjusting frames 2. The top of the clamping base 1 and the bottom of the adjusting frame 2 are movably connected. A fixed clamping ring 3 is fixedly connected to the front side of the adjusting frame 2. A movable clamping ring 4 that cooperates with the fixed clamping ring 3 is movably connected to the inner cavity of the adjusting frame 2. An adjusting shell 5 is fixedly connected to the rear side of the movable clamping ring 4. An adjusting device 6 is provided in the inner cavity of the adjusting shell 5.

[0022] refer to Figure 4 The adjusting device 6 includes two adjusting right-angle blocks 601. The side of the adjusting right-angle block 601 near the adjusting frame 2 passes through the adjusting shell 5 and extends to the outside of the inner cavity of the adjusting shell 5. A spring 602 is fixedly connected to the front side of the adjusting right-angle block 601. The surface of the spring 602 is fixedly connected to the inner cavity of the adjusting shell 5. A square outer shell 603 is fixedly connected to the rear side of the adjusting right-angle block 601. A square inner rod 604 is movably connected to the inner cavity of the square outer shell 603. The inner cavity of the square outer shell 603 is movably connected to the surface of the square inner rod 604. The surface of the square inner rod 604 is fixedly connected to the inner cavity of the adjusting shell 5.

[0023] The above solution is adopted: by setting the adjustment device 6, when the height position of the movable clamping ring 4 needs to be adjusted according to the size of the metal tube, the adjustment device 6 has the function of adjusting the position of the movable clamping ring 4.

[0024] refer to Figure 4Two right-angled adjusting blocks 601 are fixedly connected to circular columns 7 on opposite sides. The inner cavity of the adjusting shell 5 is movably connected to two rotating frames 8 that cooperate with the circular columns 7 via a rotating shaft. The inner cavity of the rotating frames 8 is movably connected to the surface of the circular columns 7.

[0025] Using the above scheme: By setting up a circular column 7 and a rotating frame 8, when the rotating frame 8 rotates, it can generate a squeezing force on the circular column 7. The circular column 7 subjected to the squeezing force can drive the adjusting right-angle block 601 to move.

[0026] refer to Figure 4 The inner cavity of the adjusting shell 5 is movably connected to two extrusion control frames 9 that cooperate with the rotating frame 8. The surface of the extrusion control frame 9 is in contact with the surface of the rotating frame 8. The rear side of the extrusion control frame 9 penetrates the adjusting shell 5 and extends to the outer side of the inner cavity of the adjusting shell 5. The rear side of the adjusting shell 5 is fixedly connected to a limiting frame 10 that cooperates with the extrusion control frame 9. The surface of the limiting frame 10 is movably connected to the inner cavity of the extrusion control frame 9.

[0027] The above scheme is adopted: by setting the extrusion control frame 9 and the limiting frame 10, the extrusion control frame 9 is pulled to move along the surface of the limiting frame 10. The limiting frame 10 has a limiting effect on the movement position of the extrusion control frame 9. When the extrusion control frame 9 moves, it can generate extrusion force on the rotating frame 8.

[0028] refer to Figure 3 The rear side of the adjustment frame 2 is provided with a right-angle groove 11 that works with the right-angle block 601. The surface of the right-angle block 601 contacts the inner cavity of the right-angle groove 11. There are several right-angle grooves 11 and they are evenly distributed on the rear side of the adjustment frame 2.

[0029] The above solution is adopted: by setting the right angle groove 11, when the adjusting shell 5 and the moving clamping ring 4 move to the appropriate position, the squeezing control frame 9 is released, and the restoring force generated by the spring 602 returning to its shape will drive the adjusting right angle block 601 to be inserted into the inner cavity of the right angle groove 11. The cooperation between the adjusting right angle block 601 and the right angle groove 11 has a limiting effect on the position of the adjusting shell 5 and the moving clamping ring 4.

[0030] refer to Figure 2 The bottom of the adjustment frame 2 is fixedly connected to the plug-in block 12. The inside of the clamping base 1 is provided with several plug-in slots 13 that cooperate with the plug-in block 12. The surface of the plug-in block 12 is movably connected to the inner cavity of the plug-in slot 13.

[0031] The above solution is adopted: by setting the insertion block 12 and the insertion slot 13, when the insertion block 12 moves into the inner cavity of the insertion slot 13, it can drive the movable clamping ring 4 and the fixed clamping ring 3 to move to the top of the clamping base 1. The cooperation of the insertion block 12 and the insertion slot 13 allows the movable clamping ring 4 and the fixed clamping ring 3 to be limited to an appropriate position according to the length of the metal tube.

[0032] refer to Figure 2 A baffle groove 14 is provided on the left side of the clamping base 1. A baffle 15 is movably connected to the inner cavity of the baffle groove 14. The rear side of the baffle 15 contacts the surface of the insertion block 12.

[0033] The above scheme is adopted: by setting baffle 15 and baffle groove 14, when the plug-in block 12 moves into the inner cavity of the plug-in groove 13, baffle 15 is moved into the inner cavity of baffle groove 14. When the rear side of baffle 15 contacts the surface of plug-in block 12, baffle 15 has a restrictive effect on the position of plug-in block 12.

[0034] The working principle of this utility model:

[0035] When using the clamping fixture for laser cutting, if a more stable clamping force is required on the metal tube, the user first inserts the insertion block 12 into the appropriate insertion slot 13 according to the length of the metal tube. Simultaneously, the insertion block 12 will move the fixed clamping ring 3 and the movable clamping ring 4 to the top of the clamping base 1. Then, the baffle 15 is moved into the inner cavity of the baffle groove 14. When the rear side of the baffle 15 contacts the front side of the insertion block 12, the position of the insertion block 12 is restricted. Next, the metal tube is placed on top of the fixed clamping ring 3. Then, the extrusion control frames 9 are pulled towards opposite sides, causing them to move along the surface of the limiting frame 10. When the extrusion control frames 9 move, they will exert extrusion force on the rotating frame 8. The rotating frame 8, subjected to this extrusion force, will exert extrusion force on the circular column 7. The two circular columns 7 subjected to this extrusion force will move backward. When the circular columns 7 move, they will... The adjustment right-angle block 601 will move backward. When the adjustment right-angle block 601 moves, it will cause the square outer shell 603 to move along the surface of the square inner rod 604. At the same time, the force generated by the movement of the adjustment right-angle block 601 causes the spring 602 to undergo elastic deformation. When the adjustment right-angle block 601 disengages from the right-angle groove 11 and moves completely into the inner cavity of the adjustment shell 5, it pulls the moving clamping ring 4 towards the side closer to the metal tube. When the bottom of the moving clamping ring 4 contacts the surface of the metal tube, the squeezing control frame 9 is released. The restoring force generated by the spring 602 returning to its shape will cause the adjustment right-angle block 601 to be inserted into the inner cavity of the right-angle groove 11. The cooperation of the adjustment right-angle block 601 and the right-angle groove 11 has a limiting effect on the position of the adjustment shell 5 and the moving clamping ring 4. The setting of the moving clamping ring 4 and the fixed clamping ring 3 has a limiting effect on the position of the metal tube. At this time, the clamping fixture used for laser cutting completes a more stable clamping of the metal tube.

[0036] In summary, this laser cutting clamping fixture, through the coordinated use of the adjustment device 6, the adjusting right-angle block 601, the spring 602, the square outer shell 603, and the square inner rod 604, solves the problem commonly encountered in existing laser cutting technology for cutting metal tubes. This laser cutting clamping fixture is a specialized auxiliary tool for laser cutting equipment, ensuring that the metal tube does not move during the cutting process, thus guaranteeing cutting accuracy and quality. Typically, clamping fixtures use bolts to adjust the clamping components to position the metal tube. Bolt adjustment is cumbersome, and the accuracy of bolt adjustment is easily affected by the skill level of the technician, leading to a decrease in clamping accuracy. Furthermore, bolt adjustment is time-consuming and inconvenient. However, existing laser cutting clamping fixtures lack components for more stable clamping of the metal tube.
