Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically to an inverted precision laser cutting machine. Background Technology

[0002] Laser processing is a processing technology that uses a high-power laser beam to cut, weld, surface treat, drill, and micro-machine workpieces. Due to its advantages such as small spot size, concentrated energy, small heat-affected zone, and non-contact with the workpiece, laser processing has been widely used as an advanced manufacturing technology in the fields of automobiles, electronics, electrical appliances, aerospace, metallurgy, and machinery manufacturing.

[0003] Laser cutting machines are high-precision processing equipment. They can process very small wedge angles, high aspect ratio cuts, irregular shapes, etc., with small kerfs, smooth cut surfaces, and high cutting accuracy.

[0004] Existing enclosed laser cutting machines typically consist of a gantry frame mounted on the machine frame, with a three-axis moving module and laser cutter installed on the gantry frame. The laser cutting machine is then enclosed by an outer casing, and laser processing takes place inside the casing. Laser processing generates a large amount of dust, which, over time, settles on components such as the guide rails of the three-axis moving module, thus affecting the processing accuracy. Summary of the Invention

[0005] The purpose of this invention is to further reduce the impact of dust on the moving module and improve the processing accuracy of the equipment by designing a suspended laser cutting machine.

The laser cutting head is installed on the slide of the Z-axis module.

[0007] Preferably, a triangular support frame is provided between the support column and the stabilizing platform. The triangular support frame includes a pressure plate and a reinforcing plate. The pressure plate is fixed on the support column, and the stabilizing platform is installed on the pressure plate. The support column is provided with a fixing hole, and the reinforcing plate is provided with an insert block. The reinforcing plate is inserted into the fixing hole through the insert block, and its top is fixed to the pressure plate.

[0008] Preferably, it also includes a reinforcing frame, which is mounted on the X-axis module and the side of the Z-axis module is fixedly connected to the reinforcing frame.

[0009] Preferably, the bottom of the X-axis module is also provided with a conduit fixing bracket.

[0010] Preferably, the stabilizing platform is made of marble.

[0011] Preferably, the support column has a lower housing and an upper housing on its outer side, and the lower housing and the upper housing are respectively provided with door panels, and the upper housing is also provided with a main unit bracket.

[0012] Compared with the prior art, the beneficial effects of this utility model are: by inverting the three-axis moving module and the laser cutter on the top, the interference of dust and waste residue on the moving module is reduced, thereby improving the laser processing accuracy during long-term use; there is no interference from the moving module and the laser on the machine base table, which allows for more flexible installation of extension parts and material clamps.

Detailed Implementation

[0015] 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.

[0016] like Figures 1-7 As shown, this utility model provides a technical solution: an inverted precision laser cutting machine, including a base 1, support columns 2, a processing table 3, a stabilizing table 4, a Y-axis module 5, an X-axis module 6, a Z-axis module 7, and a laser cutting head 8. Support columns 2 are respectively provided at the four corners of the top of the base 1. The processing table 3 is fixedly installed in the middle of the four support columns 2, and the processing table 3 is used to fix the workpiece to be processed. The stabilizing table 4 is set on top of the support columns 2. The Y-axis module 5 is installed at the bottom of the stabilizing table 4, and the X-axis module 6 is installed at the bottom of the stabilizing table 4. The Y-axis module 5 is mounted on a slide table, the Z-axis module 7 is mounted on a slide table of the X-axis module 6, and the laser cutting head 8 is mounted on a slide table of the Z-axis module 7. The Y-axis module 5, X-axis module 6, and Z-axis module 7 are all linear modules. The Y-axis module 5 and X-axis module 6 are both installed upside down, with the guide rail on top and the slide table on the bottom. This upside-down and module-upside-down installation method prevents dust and waste generated during laser processing from falling onto the guide rail, thus avoiding the impact of dust on the three-axis moving modules.

[0017] The stabilizing platform 4 serves as the mounting base for the three-axis moving module and the laser cutter. To improve its stability, it is made of a single large piece of marble, resulting in a relatively heavy platform. To better secure the stabilizing platform 4, a triangular support frame 9 is provided between the support column 2 and the stabilizing platform 4. The triangular support frame 9 includes a pressure plate 901 and a reinforcing plate 902. The pressure plate 901 is fixed to the support column 2, and the stabilizing platform 4 is mounted on the pressure plate 901. The support column 2 has a fixing hole 201, and the reinforcing plate 902 has an insert 903. The reinforcing plate 902 is inserted into the fixing hole 201 through the insert 903, and its top is fixed to the pressure plate 901. The triangular support frame 9 increases the pressure-bearing area, thereby better distributing the pressure to the support column, making the stabilizing platform 4 more stable during use.

[0018] To enhance the rigidity of the Z-axis module 7, a reinforcing frame 10 is provided. The reinforcing frame 10 is installed on the X-axis module 6, and the side of the Z-axis module 7 is fixedly connected to the reinforcing frame 10. The reinforcing frame 10 surrounds and fixes the Z-axis module 7, reducing the shaking generated when the Z-axis module 7 moves in the XY direction.

[0019] At the bottom of the X-axis module 6, there is also a conduit fixing bracket 11 to facilitate the fixing of the movable module and the circuit and pneumatic cables of the laser.

[0020] A lower housing 12 and an upper housing 13 are provided on the outside of the support column 2. A door panel is provided on the lower housing 12, and components such as double doors, flip doors and observation windows are provided on the upper housing 13, thereby forming a sealed laser cutting space. A host bracket 14 is also provided on the upper housing 13 for fixing the monitor and mouse and keyboard.

[0021] In summary, by suspending the three-axis moving module and laser cutter at the top, and using an inverted XY module, dust and waste will naturally fall due to gravity. The installation of these components at the top reduces the interference of dust and waste on the moving module and laser cutter, thereby improving the accuracy of the equipment during long-term use.

[0022] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
