Description

Technical Field

[0001] The utility model relates to the field of laser cutting machines, and particularly relates to a crossbeam carriage mounting structure of a laser cutting machine. Background Art

[0002] A laser cutting machine is a laser device that uses a laser to cut plates. The laser cutting machine mainly includes two longitudinally extending beds, a workbench arranged between the two beds, a crossbeam carriage spanning across the two beds, an x-axis driving mechanism for driving the crossbeam carriage to move back and forth, a y-axis carriage slidably arranged on the crossbeam carriage along the y-axis, a y-axis driving mechanism for driving the y-axis carriage to move left and right, a z-axis carriage slidably arranged on the y-axis carriage, a laser cutting head arranged on the z-axis carriage, and a z-axis driving mechanism for driving the z-axis carriage to move up and down. The crossbeam carriage needs to be connected to the x-axis guide rails on the two beds through x-axis sliders. However, the crossbeam carriage has a large spanning length and a heavy mass, making the installation difficult and inefficient. The installation hole positions at the left and right ends where the crossbeam carriage is fixedly matched with the x-axis sliders require high-precision opening requirements to ensure that both ends of the crossbeam carriage can be smoothly screwed to the x-axis sliders on the corresponding x-axis guide rails.

[0003] It can be seen that the prior art still needs to be improved. Summary of the Utility Model

[0004] In view of the above deficiencies of the prior art, the purpose of the present utility model is to provide a crossbeam carriage mounting structure, aiming to reduce the installation difficulty and improve the installation efficiency.

[0005] To achieve the above purpose, the present utility model adopts the following technical solutions:

[0006] A crossbeam carriage mounting structure of a laser cutting machine, wherein the crossbeam carriage is slidably arranged on a first bed and a second bed. The crossbeam carriage includes a crossbeam main body and a first support and a second support respectively arranged at both ends of the crossbeam main body. The crossbeam main body, the first support, and the second support form a gantry structure. A first slider is fixed to the bottom of the first support, and the first slider is slidably connected to a first guide rail on the first bed. A second guide rail on the second bed is connected to the bottom surface of a skateboard through a second slider. The first guide rail and the second guide rail extend longitudinally. A floating support assembly is arranged on the skateboard, and the second support is connected to the floating support assembly.

[0007] As a further improvement of the above technical solution, the floating support assembly includes a third guide rail arranged on the skateboard and extending transversely and a third slider slidably connected to the third guide rail.

[0008] As a further improvement of the above technical solution, two sets of floating support assemblies are provided.

[0009] As a further improvement of the above technical solution, a first inner plate connected to one of the floating support components and a second inner plate connected to the other floating support component are provided inside the second support.

[0010] As a further improvement of the above technical solution, a space for the slide plate to be embedded and enabling relative movement between the second support and the slide plate is provided at the bottom of the second support.

[0011] As a further improvement of the above technical solution, the first support is composed of a bottom plate and multiple enclosing plates.

[0012] As a further improvement of the above technical solution, safety light curtains are provided on both the first support and the second support.

[0013] Advantages of the present utility model: Compared with the traditional installation method that requires precise alignment of both ends of the crossbeam carriage simultaneously, which is complex and time-consuming, the crossbeam carriage installation structure provided by the present utility model first installs with the first support as a reference, and then adopts the connection method of the floating support component and the second support, which can be finely adjusted according to the installation hole positions on the second support, ensuring that the second support and the second slider on the slide plate can be quickly and reliably connected into a whole, thereby reducing the installation difficulty and improving the installation efficiency.

Detailed Embodiment

[0018] The utility model provides a crossbeam carriage mounting structure for a laser cutting machine. To make the purpose, technical solution and effects of the utility model clearer and more definite, the following further elaborates on the utility model with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0019] Please refer to Figure 1 , the utility model provides a crossbeam carriage mounting structure for a laser cutting machine. The crossbeam carriage is slidably arranged on a first bed body and a second bed body. The crossbeam carriage includes a crossbeam main body and a first support and a second support respectively arranged at both ends of the crossbeam main body. The crossbeam main body, the first support and the second support form a gantry structure, and the crossbeam main body, the first support and the second support can be spliced into one body by welding; a first slider is fixed at the bottom of the first support, and the first slider is slidably connected with a first guide rail on the first bed body. A second guide rail on the second bed body is connected with the bottom surface of a slide plate through a second slider. The first guide rail and the second guide rail extend longitudinally. A floating support assembly is arranged on the slide plate, and the second support is connected with the floating support assembly.

[0020] During actual assembly, the first guide rail on the first bed body has been pre-assembled with the first slider slidably connected thereto. Similarly, the second guide rail on the second bed body has been pre-assembled with the second slider slidably connected thereto. The second slider is pre-connected with the slide plate, so that the second slider can move back and forth; then the crossbeam carriage is hoisted and installed. First, the bottom plate of the first support of the crossbeam carriage is screwed to the first slider, that is, the first support is used as the installation reference, and then the second support is installed. Since the floating support assembly on the slide plate can horizontally move and adjust its connection position with the second support according to the installation hole positions on the second support, it is ensured that the second support can be installed quickly and accurately, thereby reducing the installation difficulty and improving the installation efficiency.

[0021] Compared with the traditional installation method that requires precise alignment of both ends of the crossbeam carriage at the same time, which is complex and time-consuming in operation, the crossbeam carriage mounting structure provided by the utility model takes the first support as the reference for prior installation, and then adopts the connection method of the floating support assembly and the second support, which can be finely adjusted according to the installation hole positions on the second support, ensuring that the second support and the second slider on the slide plate can be quickly and reliably connected into a whole, thereby reducing the installation difficulty and improving the installation efficiency.

[0022] Preferably, the floating support assembly includes a third guide rail disposed on the slide plate and extending transversely and a third slider slidably connected to the third guide rail. Since the third slider can slide freely transversely on the third guide rail, the third slider moves to a matching position according to the installation hole position on the second support, and then the inner plate in the second support is screwed to the third slider. The design of the third guide rail and the third slider provides a very large installation tolerance for the transverse installation of the second support, greatly reducing the production requirements of the crossbeam slide, thereby reducing the manufacturing cost.

[0023] The laser cutting machine will generate heat when working, which will cause the metal parts such as the beam slide to expand thermally, especially the beam body will expand to both ends to release thermal stress. If the lateral position of the first support and the second support cannot be adaptively changed, that is, the first support and the second support limit the outward expansion of the beam body, then the beam body can only be deformed up and down inside, that is, the horizontally extended beam body is deformed into an upper arch or a lower arch under the action of thermal stress; which then causes the Y-axis guide rail on the beam body to deform, thereby affecting the cutting accuracy. In the beam slide installation structure provided by the utility model, the lateral position of the second support can be dynamically adjusted. When the beam slide undergoes thermal expansion, the first support is limited, and the beam body will prompt the second support to slide outward to release thermal stress. The third slider moves with the second support. The third slider achieves the effect of floating support for the second support, ensuring that the beam body maintains straightness.

[0024] In addition, the dynamic positioning design composed of the second support and the floating support assembly can help absorb and disperse the vibrations generated during the cutting process, preventing these vibrations from being directly transmitted to the fixed end of the first support, thereby reducing the vibration accumulation in the entire system and improving the stability and accuracy of cutting.

[0025] In this embodiment, two groups of floating support assemblies are provided. The two groups of floating support assemblies can form a more reliable support bearing capacity for the second support, and the two groups of floating support assemblies can also share the load with each other. The two groups of floating support assemblies can provide a more uniform distribution of supporting force, which means that the stability of the second support during movement will be significantly improved, reducing the deflection or shaking that may be caused by single-point support, and ensuring the accuracy and stability during the cutting process.

[0026] Since the second support is composed of a surrounding plate, the interior of the second support is hollow. Therefore, a first inner plate connected to one of the floating support components and a second inner plate connected to the other floating support component are provided inside the second support. That is, the first inner plate and the second inner plate are screwed to the corresponding third sliders, and the assembly is simple. The first inner plate and the second inner plate are built into the second support, which can not only enhance the mechanical strength and stability of the second support, but also the double connection points of the first inner plate and the second inner plate with the floating support components ensure the stable combination of the second support and the slide plate, and the structural integrity can be maintained even in a high-intensity working environment.

[0027] Preferably, a space for the slide plate to be embedded is provided at the bottom of the second support, enabling relative movement between the second support and the slide plate. On the one hand, the internal space of the second support is reasonably utilized, allowing the floating support components to be hidden inside the second support. On the other hand, the dynamic position adjustment of the second support does not interfere with the slide plate.

[0028] The first support is composed of a bottom plate and multiple surrounding plates, forming a more robust framework that can withstand greater loads and reduce deformation caused by external forces. The first support composed of multiple surrounding plates can better isolate the heat generated in the cutting area, prevent heat diffusion from affecting other sensitive components, and at the same time, the channels formed between the surrounding plates are conducive to air circulation to assist in heat dissipation. The bottom plate of the first support is provided with mounting holes that cooperate with the first slider and can be directly screwed to the first slider.

[0029] Drive motors are provided on the first support and the second support. The drive motors are drivingly connected to gears, and the gears are in transmission connection with the racks on the first bed body and the second bed body. When the laser cutting machine is working, the crossbeam carriage moves back and forth under the drive of the drive motor. To avoid collisions between the staff and the crossbeam carriage, safety light curtains are provided on both the first support and the second support. It can be understood that a set of safety light curtains includes a transmitter and a receiver. The transmitter is arranged on the crossbeam carriage, and the receiver is arranged on the bed body. The transmitter emits infrared rays towards the receiver to form a pair of rays. The safety light curtain forms a virtual protective wall through the infrared beam. Once a person or an object enters the detection range of the light curtain, the safety mechanism is immediately triggered, causing the drive motor to stop running and the movement of the crossbeam carriage to pause immediately, effectively avoiding potential collision injuries.

[0030] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0031] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "coupled" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection, an electrical connection or a connection that can communicate with each other; it may be a direct connection, or an indirect connection through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements.

[0032] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solutions and the inventive concept of the present utility model, and all such changes or substitutions should fall within the protection scope of the present utility model.
