Description

Technical Field

[0001] This utility model relates to the field of laser processing equipment technology, and in particular to a gantry structure for a laser processing center. Background Technology

[0002] A laser cutting machine uses a laser beam emitted from a laser source, which is focused into a high-power-density beam through an optical path system. This beam irradiates the workpiece surface, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas, coaxial with the beam, blows away the molten or vaporized metal, thus achieving the cutting purpose. The gantry structure of a laser processing center is a high-rigidity frame system. Columns support beams to form a portal frame, providing a stable motion platform for laser processing.

[0003] Chinese Patent No. CN216607661U discloses a novel laser cutting machine, comprising a main structure. The main structure includes a machine base, a set of linear transmission mechanisms disposed on the end face of the machine base, a gantry-type mounting frame, a first Y-axis transmission mechanism fixedly disposed on the end face of the gantry-type mounting frame, a side mounting plate, and a lifting mechanism fixedly disposed on the end face of the side mounting plate, and a laser cutting machine. The laser cutting machine housing achieves displacement adjustment in the X, Y, and Z axes through the linear transmission mechanisms, the first Y-axis transmission mechanism, and the lifting mechanism. A workpiece table is set on the machine base, and the workpiece to be cut is placed on the workpiece table. In addition, a waste exhaust fan or a CCD image detection device is provided. The waste exhaust fan can further blow the waste material to the waste exhaust trough, while the CCD image detection device can remotely monitor the cutting effect of the workpiece.

[0004] However, the above technical solution has the following shortcomings: the gantry of the laser cutting machine lacks a structure for local absorption and treatment of the fumes generated during cutting, which causes the fumes to spread. It only relies on a large hood on the outside of the device to be used in conjunction with a fan to extract the fumes, but this design is not conducive to the precision processing of high-value materials and limits the applicability of the device. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a gantry structure for laser processing center equipment. By setting an efficient smoke removal structure on the gantry mounting frame, it can achieve a good smoke removal effect in combination with traditional large-hood smoke removal equipment, thereby expanding the applicability of the device.

[0006] The technical solution of this utility model is a gantry structure for a laser processing center, including a worktable and a smoke removal mechanism. A gantry-type mounting frame is provided above the worktable, a movable seat is provided on the gantry-type mounting frame, and a mounting base is provided on the movable seat. The smoke removal mechanism includes a support on the mounting base, a collection and treatment box on the support, two negative pressure air ducts, both connected to the collection and treatment box and made of soft material, a rigid pipe connected to the negative pressure air ducts, a dust suction hood provided at the end of the rigid pipe away from the negative pressure air duct, and a mounting assembly provided on the mounting base. The mounting assembly includes a fixed frame, a mounting plate provided on the fixed frame, and multiple fixing bolts distributed in a ring array and penetrating the mounting plate. The fixing bolts are threadedly connected to the mounting base, and the rigid pipe is provided on the fixed frame.

[0007] Preferably, the mounting base is provided with a cutting assembly, which includes a push cylinder mounted on the mounting base, a lifting seat driven and connected to the push cylinder, and a cutting machine body mounted on the lifting seat; two dust suction hoods are located on both sides of the cutting machine body.

[0008] Preferably, the distance between the cutting head and the dust hood is less than one centimeter.

[0009] Preferably, the lifting base is provided with a guide block, and the mounting base is provided with a groove for the guide block to slide vertically.

[0010] Preferably, a support plate is provided on the gantry-type mounting frame, and a first movable block is provided on the support plate, which moves longitudinally on the worktable.

[0011] Preferably, the support plate is provided with multiple rectangular arrays of housings, and the interior of the housings is movably connected to omnidirectional balls, which are rolled on the worktable.

[0012] Preferably, a second movable block is provided on the movable base, and the second movable block moves laterally on the gantry-type mounting frame.

[0013] Preferably, the gantry-type mounting bracket is provided with two horizontally distributed guide rails, and the movable seat is provided with a limit slider, which is slidably connected to the guide rails.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] This utility model, through its smoke removal mechanism, enables the cutting machine to capture over 90% of the smoke and dust before it diffuses when cutting high-precision workpieces. This avoids secondary dust diffusion caused by airflow disturbances in large-scale smoke removal equipment. When used in conjunction with a large-scale smoke removal device installed on the outside of the workbench, it expands the applicability of the device. At the same time, the installation components facilitate the replacement or maintenance of the pipeline structure, improving the ease of use of the equipment and demonstrating its practicality.

[0021] Example 1

[0022] like Figure 1 - Figure 4 As shown in the figure, the gantry structure of the laser processing center equipment proposed in this embodiment includes a worktable 1 and a smoke removal mechanism; a gantry-type mounting frame 2 is provided above the worktable 1, a movable seat 3 is provided on the gantry-type mounting frame 2, a mounting seat 4 is provided on the movable seat 3, and a cutting assembly is provided on the mounting seat 4. The cutting assembly includes a push cylinder 5 provided on the mounting seat 4, a lifting seat 6 drivenly connected to the push cylinder 5, and a cutting machine body 7 provided on the lifting seat 6; two dust suction hoods 12 are respectively located on both sides of the cutting machine body 7, and the distance between the cutting head and the dust suction hood 12 is less than 3 cm.

[0023] The smoke removal mechanism includes a support 8 mounted on the mounting base 4, a collection and treatment box 9 mounted on the support 8, two negative pressure ducts 10, both connected to the collection and treatment box 9 and made of soft material, a rigid pipe 11 connected to the negative pressure duct 10, a dust collection hood 12 mounted on the end of the rigid pipe 11 away from the negative pressure duct 10, and a mounting assembly mounted on the mounting base 4. The mounting assembly includes a fixing frame 13, a mounting plate 14 mounted on the fixing frame 13, and multiple fixing bolts 15 arranged in a ring array and penetrating the mounting plate 14. The fixing bolts 15 are threaded onto the mounting base 4, and the rigid pipe 11 is mounted on the fixing frame 13.

[0024] In this embodiment, the internal structure of the collection and processing box 9 is equipped with a negative pressure fan (not shown) so that the suction force generated at the dust hood 12 absorbs the fumes produced during cutting. When the cutting machine body 7 is cutting the workpiece, the negative pressure fan generates suction, and the dust hood 12 absorbs the fumes generated during cutting. The fumes then enter the collection and processing box 9 through the rigid pipe 11 and the negative pressure air duct 10, where they are absorbed and treated by the processing liquid. The position design of the dust hood 12 ensures efficient suction, reduces the escape of fumes, and facilitates the removal of fumes when necessary. When replacing or repairing the pipeline structure, the fixing bracket 13 can be disassembled by screwing the fixing bolts 15 off the mounting base 4 and mounting plate 14, thereby enabling the pipeline structure to be replaced or repaired, which improves the ease of use of the equipment. At the same time, the following flue gas treatment structure enables the cutting machine to capture more than 90% of the dust before it spreads when cutting high-precision workpieces, avoiding the secondary diffusion of dust caused by airflow disturbance in large-scale smoke removal equipment, expanding the applicability of the device and making it highly practical.

[0025] It should be noted that the outer side of the workbench 1 can be equipped with a wrap-around cover and a centrifugal fan to achieve the function of smoke extraction and dust removal when cutting a large number of workpieces continuously and generating a large amount of smoke. The application range of the device can be expanded when used in conjunction with the dust removal mechanism.

[0026] Example 2

[0027] like Figure 3 As shown in the figure, the gantry structure of the laser processing center equipment proposed in this embodiment has a guide block 23 on the lifting seat 6 and a sliding groove for the guide block 23 to slide vertically on the mounting seat 4, compared with the first embodiment.

[0028] In this embodiment, the guide block 23 and the slide groove are designed to guide and stabilize the movement of the lifting seat 6, thereby ensuring the stability of the cutting machine body 7 during lifting and lowering, and ensuring the quality of cutting.

[0029] Example 3

[0030] like Figure 1 , Figure 3 and Figure 4As shown in the figure, the gantry structure of the laser processing center equipment proposed in this embodiment, compared with the first embodiment, has the following features: a support plate 16 is provided on the gantry mounting frame 2, a first moving block 17 is provided on the support plate 16, the first moving block 17 moves longitudinally on the worktable 1, a plurality of rectangular array housings 18 are provided on the support plate 16, a universal ball 19 is movably connected inside the housing 18, the universal ball 19 is rolled on the worktable 1, a second moving block 20 is provided on the moving seat 3, the second moving block 20 moves laterally on the gantry mounting frame 2, two horizontally distributed guide rails 22 are provided on the gantry mounting frame 2, and a limit slider 21 is provided on the moving seat 3, the limit slider 21 is slidably connected to the guide rails 22.

[0031] In this embodiment, the first moving block 17 is used to drive the gantry mounting frame 2 to move longitudinally and adjust, and the second moving block 20 is used to move the cutting equipment laterally, so that the cutting machine body 7 can cut the workpiece at different positions. The support plate 16 can distribute the downward pressure of the gantry mounting frame 2, and the universal ball 19 plays a supporting role, reducing the load pressure on the drive structure and extending the service life of the device. The limit slider 21 and the guide rail 22 are set to ensure the stability of the movement of the moving seat 3.

[0032] It should be noted that, since the weight of the entire frame needs to be driven, a ball screw drive or an advanced dual-drive synchronization technology combined with a cross-decoupling algorithm can be used to solve the synchronization problem of the two motors. A gantry coordinated stop function is provided to prevent mechanical damage caused by single-axis failure. A linear motor is used for drive. All of these technologies are existing molding technologies.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
