Description

Technical Field

[0001] This utility model relates to the field of waterjet cutting machine technology, and in particular to a material clamping and traction structure for waterjet cutting machine equipment. Background Technology

[0002] A waterjet cutter is an advanced device that uses high-pressure water jets for cutting. It pressurizes water to hundreds of megapascals using a booster pump, then ejects it through extremely fine nozzles, creating a high-speed, high-energy water jet. For cutting hard materials such as metal and stone, abrasive materials (such as garnet sand) are mixed into the water jet to enhance its cutting ability.

[0003] However, the traditional material clamping and pushing traction structure used in waterjet cutting equipment generally adopts a unidirectional clamping design, that is, only applying fixing or pushing force to one side of the material. This structure has significant defects when dealing with complex cutting scenarios: when the high-pressure water jet impacts the material surface, the unidirectional force is prone to cause slight displacement or vibration of the material. Especially when cutting thin plates, this instability will directly cause the cut to tilt, increase the edge burrs, or even the material to break. Utility Model Content

[0004] This utility model discloses a material clamping and pushing traction structure for waterjet cutting equipment, which aims to solve the problem of the significant defects of the unidirectional clamping design, that is, applying fixing or pushing force only on one side of the material, when dealing with complex cutting scenarios: when the high-pressure water jet impacts the material surface, the unidirectional force is prone to cause slight displacement or vibration of the material. Especially when cutting thin plates, this instability will directly cause the technical problem of slanted cut, increased edge burrs, or even material breakage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A material clamping and traction structure for a waterjet cutting machine includes a waterjet cutting machine assembly and two conveyor frame assemblies, and further includes:

[0007] Clamping and pushing mechanism: The clamping and pushing mechanism is set on the two conveyor frame assemblies. Support plates are set on the outer walls of both sides of the two conveyor frame assemblies. A traction frame is set on the top outer wall of the support plate via an electric guide rail. Two assembly frames are set on the top outer wall of the traction frame via an electric guide rail. A first electric telescopic rod is set on the bottom outer wall of the assembly frame. A clamping assembly is set on the movable end of the first electric telescopic rod.

[0008] Correction mechanism: The correction mechanism is installed on the bottom outer wall of the traction frame.

[0009] In this case, a bidirectional clamping structure is adopted, which solves the problem that traditional unidirectional clamping designs are prone to material displacement or vibration in complex cutting scenarios, improves cutting accuracy and stability, and is especially suitable for thin plate cutting. It reduces cut tilt and edge burrs, and reduces the risk of material breakage. The structure achieves bidirectional stable clamping and automatic correction of materials by setting clamping and pushing mechanisms and correction mechanisms. The support plates on the two conveyor frame assemblies drive the traction frame to move through electric guide rails. The first electric telescopic rod at the bottom of the assembly frame can adjust the height of the clamping assembly to ensure adaptability to materials of different thicknesses.

[0010] In a preferred embodiment, the clamping assembly includes an assembly box disposed at the movable end of the first electric telescopic rod. Two limiting slots are formed on opposite outer walls of the assembly box. Slider blocks are slidably disposed on the inner walls of the four limiting slots. Clamping plates are disposed on opposite outer walls of the two sliders. Racks are disposed on the bottom outer walls of the two clamping plates. Two assembly rods are disposed on opposite inner walls of the assembly box. Two sector wheels are disposed on the outer walls of the assembly rods, meshing with the racks. A drive assembly is disposed on each sector wheel.

[0011] Specifically, an innovative gear and sector wheel transmission structure is adopted to achieve synchronous and symmetrical movement of the clamping plates. The limiting slots and slider structure in the assembly box ensure the linearity and stability of the clamping plate movement, while the meshing design of the sector wheel and rack makes the clamping force distribution more uniform. When the material is fed into the clamping area, the sliders in the four limiting slots guide the clamping plates to move in parallel. The racks at the bottom of the two clamping plates mesh with the sector wheels to ensure that the clamping forces on both sides are completely symmetrical. This design eliminates the material twisting and deformation caused by asynchrony in traditional clamping devices, and is particularly suitable for clamping brittle materials.

[0012] In a preferred embodiment, the correction mechanism includes two push plates, a groove is provided on the bottom outer wall of the traction frame, and a bidirectional threaded rod is provided on the inner wall of the opposite side of the groove via a bearing. Both push plates are provided on the outer wall of the bidirectional threaded rod, and a motor is externally connected to one end of the threaded rod.

[0013] In particular, the push plate design driven by a bidirectional threaded rod enables real-time automatic correction of the material position. The motor drives the bidirectional threaded rod to rotate, causing the two push plates to move synchronously in opposite directions along the slide. The guide design of the slide ensures smooth push plate movement, accurately adjusts the material position, and improves production efficiency and product consistency.

[0014] As described above, a material clamping and traction structure for a waterjet cutting machine includes a waterjet cutting machine assembly and two conveyor frame assemblies. It further includes: a clamping and pushing mechanism: the clamping and pushing mechanism is mounted on the two conveyor frame assemblies. Support plates are provided on both outer walls of the two conveyor frame assemblies. A traction frame is mounted on the top outer wall of the support plates via an electric guide rail. Two assembly frames are mounted on the top outer wall of the traction frames via an electric guide rail. A first electric telescopic rod is mounted on the bottom outer wall of the assembly frame, and a clamping assembly is mounted on the movable end of the first electric telescopic rod. A correction mechanism: the correction mechanism is mounted on the bottom outer wall of the traction frame. The material clamping and traction structure for a waterjet cutting machine provided by this utility model has the technical effect of improving cutting accuracy and stability.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0021] The material clamping and pushing traction structure disclosed in this utility model for waterjet cutting equipment is mainly used in unidirectional clamping designs, that is, only applying fixing or pushing force to one side of the material. This structure has significant defects when dealing with complex cutting scenarios: when high-pressure water jets impact the surface of the material, unidirectional force can easily cause the material to deviate slightly or vibrate. Especially when cutting thin plates, this instability can directly cause the cut to tilt, increase the edge burrs, or even the material to break.

[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A material clamping and pushing traction structure for a waterjet cutting machine includes a waterjet cutting machine assembly 1 and two conveyor frame assemblies 2, and further includes: a clamping and pushing mechanism: the clamping and pushing mechanism is disposed on the two conveyor frame assemblies 2, and a support plate 4 is disposed on the outer walls of both sides of the two conveyor frame assemblies 2. A traction frame 3 is disposed on the top outer wall of the support plate 4 via an electric guide rail. Two assembly frames 5 are disposed on the top outer wall of the traction frame 3 via an electric guide rail. A first electric telescopic rod 9 is disposed on the bottom outer wall of the assembly frame 5, and a clamping assembly is disposed on the movable end of the first electric telescopic rod 9; a correction mechanism: the correction mechanism is disposed on the bottom outer wall of the traction frame 3.

[0023] In the specific implementation process, a two-way clamping structure is adopted, which solves the problem that traditional one-way clamping design is prone to material deviation or vibration in complex cutting scenarios, improves cutting accuracy and stability, and is especially suitable for thin plate cutting. It reduces cut tilt and edge burrs, and reduces the risk of material breakage. The structure realizes two-way stable clamping and automatic correction of materials by setting clamping and pushing mechanism and correction mechanism. The support plate 4 on the two conveyor frame components 2 drives the traction frame 3 to move through the electric guide rail. The first electric telescopic rod 9 at the bottom of the assembly frame 5 can adjust the height of the clamping component to ensure adaptability to materials of different thicknesses.

[0024] Reference Figure 2 , Figure 3 and Figure 4In a preferred embodiment, the clamping assembly includes an assembly box 10, which is disposed at the movable end of the first electric telescopic rod 9. Two limiting slots 15 are provided on the outer wall of each opposite side of the assembly box 10. Slider 14 is slidably disposed on the inner wall of each of the four limiting slots 15. Clamping plates 11 are disposed on the outer wall of each of the two sliders 14 on opposite sides. Racks 16 are disposed on the bottom outer wall of each of the two clamping plates 11. Two assembly rods 17 are disposed on the inner wall of each opposite side of the assembly box 10. Two sector wheels 20 are disposed on the outer wall of the assembly rods 17. The sector wheels 20 mesh with the racks 16. A drive assembly is disposed on the sector wheels 20.

[0025] Specifically, an innovative gear and sector wheel 20 transmission structure is adopted to achieve synchronous and symmetrical movement of the clamping plate 11. The limiting slots 15 and sliders 14 in the assembly box 10 ensure the linearity and stability of the movement of the clamping plate 11. The meshing design of the sector wheel 20 and the rack 16 makes the clamping force distribution more uniform. When the material is fed into the clamping area, the sliders 14 in the four limiting slots 15 guide the clamping plate 11 to move in parallel. The racks 16 at the bottom of the two clamping plates 11 mesh with the sector wheel 20 to ensure that the clamping force on both sides is completely symmetrical. This design eliminates the material twisting and deformation caused by asynchrony in traditional clamping devices and is particularly suitable for clamping brittle materials.

[0026] Reference Figure 4 In a preferred embodiment, the drive assembly includes a second electric telescopic rod 18, which is disposed on the bottom inner wall of the assembly box 10. The movable end of the second electric telescopic rod 18 is provided with a mounting bracket 19, and both ends of the mounting bracket 19 are hinged with connecting plates 22. Both fan-shaped wheels 20 are provided with connecting brackets 21, and the outer walls on both sides of the connecting plate 22 are hinged to the connecting brackets 21.

[0027] The second electric telescopic rod 18 uses the hinge structure of the mounting frame 19, the connecting plate 22 and the connecting frame 21 to convert linear motion into precise rotational motion of the sector wheel 20. The rotation of the sector wheel 20 and the gears cooperate to achieve relative clamping of the two clamping plates 11.

[0028] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the correction mechanism includes two push plates 7, a groove 12 is provided on the bottom outer wall of the traction frame 3, and a bidirectional threaded rod 13 is provided on the inner wall of the opposite side of the groove 12 through a bearing. Both push plates 7 are provided on the outer wall of the bidirectional threaded rod 13, and a motor 6 is externally connected to one end of the threaded rod.

[0029] In particular, the push plate 7 is designed with a bidirectional threaded rod 13 to drive it, which realizes real-time automatic correction of the material position. The motor 6 drives the bidirectional threaded rod 13 to rotate, so that the two push plates 7 move synchronously in opposite directions along the slide 12. The guiding design of the slide 12 ensures that the push plate 7 moves smoothly, accurately adjusts the material position, and improves production efficiency and product consistency.

[0030] Reference Figure 3 In a preferred embodiment, a first protective pad 8 is provided on one outer wall of the push plate 7, the slide groove 12 has a "T" shaped structure, and a second protective pad 23 is provided on one outer wall of the clamping plate 11.

[0031] It should be noted that a first protective pad 8 is added to the push plate 7. The first protective pad 8 is made of highly elastic polyurethane material, which effectively solves the problem of surface damage caused by the hard push plate 7 directly contacting the material. A second protective pad 23 is set on the clamping plate 11. The second protective pad 23 is made of wear-resistant silicone material, which solves the problem of material edge damage caused by the hard clamping plate 11 directly clamping the material.

[0032] Working principle: In use, the material is first placed on the two conveyor frame assemblies 2. The electric guide rail is started to move the traction frame 3 to a suitable position. The motor 6 drives the bidirectional threaded rod 13 to rotate, so that the two push plates 7 move synchronously in opposite directions along the slide groove 12 to realize automatic correction of the material position. Then, the first electric telescopic rod 9 on the first traction frame 3 adjusts the height of the clamping assembly to adapt to the material position. The second electric telescopic rod 18 extends and retracts. Through the transmission of the mounting frame 19, connecting plate 22 and connecting frame 21, the fan-shaped wheel 20 rotates, which drives the clamping plate 11 to move synchronously and symmetrically. After the material is stably clamped, it is pushed to the cutting area. The structure on the second traction frame 3 is the same as above to clamp the other side of the material to realize bidirectional clamping and fixing for cutting.

[0033] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
