[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese patent application number 202410118428X, filed with the Patent Office of China on January 29, 2024, entitled “A Five-Axis Laser Processing Equipment,” the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the technical field of laser processing equipment, and in particular to a five-axis laser processing equipment. Background Art

[0004] Laser processing is a field with the fastest development, widest application and greatest development potential in laser application technology. Currently, more than 20 laser processing technologies have been developed, such as laser welding, laser cutting, laser rapid prototyping, laser repair, etc., which are widely used in machinery, electronics, automobile and other industries. Compared with traditional mechanical processing methods, laser processing has incomparable advantages. Laser processing has the advantages of high processing precision, fast speed, small mechanical deformation, material saving, good flexibility and wide processing range. At the same time, laser processing can be easily combined with computer-aided manufacturing, which facilitates the control of the production process and is suitable for processing small batches, multiple varieties and complex shapes of parts.

[0005] In the field of laser cutting, five-axis laser processing equipment with five-axis linkage is usually used. It adopts a platform for coordinated movement of the workpiece along three linear axes and two rotational axes. It melts the workpiece through a focused high-power density laser beam to achieve cutting and engraving of the workpiece. Compared with the single-sided processing of three-axis linkage, the five-axis linkage realizes three-dimensional processing of the workpiece, increases the processing surface of the workpiece, improves processing efficiency, and has the ability to process workpieces with complex three-dimensional shapes. Five-axis linkage five-axis laser processing equipment can refer to a high-speed five-axis laser processing equipment disclosed in Chinese Patent Publication No. CN219616976U. The equipment comprises a machine body, which includes a base and a longitudinal mounting seat. The base and longitudinal mounting seat are respectively provided with a clamping system and a laser processing system. The clamping system includes a Y-axis linear drive mechanism, an X-axis linear drive mechanism, a bidirectional motor group, and a fixture. The bidirectional motor group includes a first rotary motor and a second rotary motor, and the rotating shaft of the first rotary motor is arranged perpendicular to the rotating shaft of the second rotary motor. The laser processing system includes a Z-axis linear drive device, a Z-axis slide, a longitudinal auxiliary drive cylinder, and a laser processing module. The longitudinal auxiliary drive cylinder is drive-connected to the Z-axis slide. The Z-axis slide is driven by the Z-axis linear drive device and the longitudinal auxiliary drive cylinder to perform a lifting motion. This can reduce the motion load of the Z-axis linear drive device, improve the movement stability and movement position accuracy of the laser processing module, and improve processing efficiency and processing accuracy.

[0006] For laser cutting of large workpieces, high-torque motors are usually used due to their large mass. Conventional five-axis laser processing equipment, after installing a high-torque motor, is prone to contact with the Z-axis drive mechanism when moving along the XY axis, making processing difficult.

[0007] Therefore, the existing technology still needs to be improved and developed.

[0050] 1 to 4 , this embodiment discloses a five-axis laser processing device, including:

[0051] The frame 10 includes a base 11 and a support 12 mounted on the base 11;

[0052] A first driving mechanism 20 is mounted on the base 11 and configured to drive the workpiece to move along the Y axis;

[0053] The swing mechanism 30 includes a high-torque motor 31 mounted at the output end of the first drive mechanism 20 and arranged along the Y-axis, a turntable 32 connected to the output shaft of the high-torque motor 31, with the output shaft of the high-torque motor 31 disposed toward the support 12. The turntable 32 includes an inclined downwardly oriented swing arm 321 and a carrier plate 322 connected to the lower end of the swing arm 321. A gap is formed between the upper end surface of the carrier plate 322 and the rotation axis of the turntable 32.

[0054] The rotation mechanism 40 is mounted on the carrier plate 322 and is configured to drive the workpiece to rotate about the C-axis, with the rotation axis of the turntable 32 intersecting the rotation axis of the rotation mechanism 40 ;

[0055] a clamp 50 mounted at the output end of the rotating mechanism 40 and configured to clamp a workpiece;

[0056] The laser module 60 includes a laser head 61 , wherein the laser output port of the laser head 61 is downwardly disposed and higher than the fixture 50 ;

[0057] The second driving mechanism 70 is mounted on the support 12 and configured to drive the laser module 60 to move along the X-axis;

[0058] The third driving mechanism 80 is mounted on the output end of the second driving mechanism 70 and is configured to drive the laser module 60 to move along the Z axis.

[0059] The five-axis laser processing equipment of this embodiment is provided with a first driving mechanism 20 on the base 11, which is configured to drive the workpiece to move along the Y-axis, a swinging mechanism 30 is provided at the output end of the first driving mechanism 20, which is configured to drive the workpiece to swing around the B-axis, a turntable 32 is provided at the output end of the swinging mechanism 30, and a rotating mechanism 40 is provided on the turntable 32, which is configured to drive the workpiece to rotate around the C-axis, and a fixture 50 is provided at the output end of the rotating mechanism 40, which is configured to clamp the workpiece. The workpiece is fixed by the fixture 50, and can move along the Y-axis when driven by the first driving mechanism 20, can swing around the B-axis when driven by the swinging mechanism 30, and can rotate around the C-axis when driven by the rotating mechanism 40.

The second driving mechanism 70 can drive the laser module 60 to move along the X-axis, and the third driving mechanism 80 can drive the laser module 60 to move along the Z-axis, thereby realizing three-dimensional processing of the workpiece by the laser module 60 with high processing accuracy.

[0060] The five-axis laser processing equipment of this embodiment can adapt to the cutting processing of large workpieces by providing a high-torque motor 31. The output end of the high-torque motor 31 is connected to a turntable 32. The turntable 32 includes a swing arm 321 and a carrier plate 322. The swing arm 321 is an inclined and sunken structure. There is a gap between the upper end surface of the carrier plate 322 and the rotation axis of the turntable 32. Through such an arrangement, the turntable 32 has a larger sinking space on the end facing the laser module 60, which is configured to install a large workpiece. In addition, the output shaft of the high-torque motor 31 is arranged toward the side of the support 12. When the workpiece moves along the Y-axis, the high-torque motor 31 will not affect the second drive mechanism 70 and the third drive mechanism 80. The structure is ingenious.

[0061] For ease of understanding, please refer to Figure 4 for the gap mentioned above. The position of the gap refers to the distance h formed between the horizontal line of the upper end surface of the carrier 322 and the rotation axis of the turntable 32. The distance h needs to be designed according to the actual size of the workpiece and is not limited to the size shown in the figure.

[0062] The five-axis laser processing equipment also includes a water cooling module, which includes a base 91 installed at the output end of the first drive mechanism 20, a sleeve 92 fixed on the base 91 and covering the high-torque motor 31, and a cold water pipe arranged in the sleeve 92. The cold water pipe is arranged around the high-torque motor 31. The sleeve 92 is also provided with a water inlet interface 93 and a drainage interface 94 connected to both ends of the cold water pipe. The base 91 is provided with an avoidance hole 911 that passes through along the Y-axis direction and is configured to pass a cable.

[0063] It should be noted that the B-axis direction mentioned in the present invention refers to the axis around which the large workpiece needs to swing, and needs to be set according to the actual processing requirements of the large workpiece. The B-axis of this embodiment is schematically illustrated using Figure 1 as an example. The direction of the swing mechanism 30 is consistent with the direction of the first drive mechanism 20, so that the B-axis and the Y-axis form parallel lines. Of course, this is just one of the settings. In other embodiments, the projections of the B-axis and the Y-axis can also be set to cross, and are not limited to the parallel setting of this embodiment. These equivalent variations or replacements are all included in the scope defined by the claims of the present invention.

[0064] In addition, the C-axis direction mentioned in the present invention is the axis around which the pointer large workpiece needs to rotate, and needs to be set according to the actual processing requirements of the workpiece. The C-axis of this embodiment is schematically illustrated using Figure 1 as an example. The direction of the rotating mechanism 40 is consistent with the direction of the third drive mechanism 80, so that the B-axis and the Z-axis form parallel lines. Of course, this is just one of the settings. In other embodiments, the B-axis and the Z-axis can also be set to be non-parallel, and are not limited to the parallel setting of this embodiment. These equivalent variations or replacements are all included in the scope defined by the claims of the present invention.

[0065] When the laser generated by the laser module 60 cuts a large workpiece, the processing position of the large workpiece is prone to overheating. In order to reduce the temperature of the cutting processing position, please refer to Figure 2. The laser module 60 of this embodiment also includes an air duct 62 that is arranged on one side of the laser head 61 and can be bent and deformed. The air outlet of the air duct 62 faces the upper end of the fixture 50. The upper end of the air duct 62 is an air inlet, which is connected to the exhaust port of the air cooler through an air duct. The cold air is increased by the air cooler and is blown to the cutting position of the large workpiece to reduce the processing temperature of the cutting position.

[0066] Please refer to Figure 6, the clamp 50 of this embodiment includes a rotating shaft 51 connected to the output end of the rotating mechanism 40, a supporting member 54 connected to the rotating shaft 51, a clamping member 52 fixed to the supporting member 54 and an adapter 53 sleeved on the clamping member 52; the supporting member 54 is provided with a limiting hole along the axial direction; the clamping member 52 is provided with an extension portion 521 at one end along the axial direction, and a tapered hole 522 and a protrusion 523 at the other end along the axis. The extension portion 521 is inserted into the limiting hole, and there is a gap between the tapered hole 522 and the protrusion 523; the adapter 53 includes a mounting portion 531 that is hollow in the middle and has elasticity and a adapter portion 532 connected to one end of the mounting portion 531 along the axial direction. The mounting portion 531 is clamped by the gap after being axially inserted into the tapered hole 522, and the adapter portion 532 has a plug hole 5321 with an open upper end.

[0067] The above-mentioned fixture can be installed in two ways according to the model of the workpiece. The first installation method is: take out the adapter 53, directly insert the plug-in end of the workpiece into the tapered hole 522 of the clamping part, and use the gap between the tapered hole 522 and the protrusion 523 to clamp the plug-in end of the workpiece, provided that the workpiece has a plug-in end that is compatible with the gap; the second installation method is: install the adapter 53 into the tapered hole 522, and use the gap between the tapered hole 522 and the protrusion 523 to clamp the mounting part 531 of the adapter 53, first complete the installation of the adapter 53, and then insert the plug-in end of the workpiece into the plug-in hole 5321 at the upper end of the adapter part 532. The size of the plug-in hole 5321 of the adapter part 532 is designed according to the size of the plug-in end of the workpiece. Therefore, different adapter parts 532 can be replaced according to the different sizes of the plug-in end of the workpiece.

[0068] A large amount of metal dust will be generated during cutting, and this metal dust is easy to accumulate in the plug hole 5321. For this reason, optionally, the adapter 532 of this embodiment is provided with an air hole 5322 along the radial direction, and the air hole 5322 is connected to the plug hole 5321. The other end of the air hole 5322 is connected to a gas generating device through a pipeline. High-pressure gas is introduced into the air hole 5322 through the gas generating device to blow away the dust in the plug hole 5321 to prevent dust from accumulating in the plug hole 5321.

[0069] Please refer to Figures 1 and 2. The bottom of the base 11 of this embodiment is provided with four adjustable horizontal support feet 111. The level of the frame 10 is adjusted by the support feet 111 to ensure the processing accuracy of the workpiece; the periphery of the support feet 111 is also provided with an anti-collision plate 112, and the bottom of the base 11 is provided with two anti-collision pads 113 arranged along the Y-axis direction. When the five-axis laser processing equipment is transported, the bottom of the base 11 can obtain a good anti-collision effect. The anti-collision plate 112 is provided with a through hole 1121 configured for bundling. When the five-axis laser processing equipment is transported, a rope is passed through the through hole 1121 to bundle the laser processing device onto the transport vehicle to avoid shaking.

[0070] Optionally, a load-bearing support foot 114 is provided between the two support feet 111 along the Y-axis direction. The support foot 114 has a good supporting effect on the middle part of the base 11, which can avoid the problem of the base 11 being sunken due to the installation of a large workpiece, thereby improving the structural stability.

The first driving mechanism 20 of this embodiment includes a first linear module 21 arranged along the Y-axis direction, a first slider 22 driven by the first linear module 21, and a first guide rail 23 arranged on both sides of the first slider 22 and slidingly matched with the first slider 22.

Under the guiding action of the first guide rail 23, the stability of the movement of the first slider 22 along the Y-axis direction can be improved.

[0072] Optionally, the first linear module 21 mentioned above adopts a linear motor. The structure of the linear motor is simple. Since the linear motor does not require additional devices to convert rotational motion into linear motion, the structure of the system itself is greatly simplified, and the weight and volume are also greatly reduced. The positioning accuracy of the linear motor is high. When linear motion is required, the linear motor can realize direct transmission, eliminating various positioning errors caused by intermediate links, so the positioning accuracy is high. The linear motor has a fast response speed, high sensitivity, and good tracking effect. The linear motor is easy to be supported by magnetic suspension, so that there is always a certain air gap between the rotor and the stator without contact, eliminating the contact friction resistance between the stators, and greatly improving the sensitivity and speed of the system. Of course, the use of a linear motor is only a preferred embodiment. In other embodiments, belt modules, rack and pinion modules, screw modules, etc. can also be used.

[0075] The third driving mechanism 80 includes a pushing device 81 arranged along the Z-axis direction, a third slider 82 driven by the pushing device 81, and a third guide rail 83 provided on both sides of the third slider 82 and slidingly engaged with the third slider 82. The laser module 60 is mounted on the third slider 82. When working, the third slider 82 is driven to move along the Z-axis direction by the pushing device 81. The third guide rail 83 is provided. Under the guiding action of the third guide rail 83, the stability of the movement of the third guide rail 83 along the Z-axis direction can be improved.

[0076] Optionally, the above-mentioned pushing device 81 adopts a linear motor. The structure of the linear motor is simple.

[0077] In order to improve the lubricity of the first guide rail 23, the second guide rail 73 and the third guide rail 83, guide rail oil is generally added to the first guide rail 23, the second guide rail 73 and the third guide rail 83. The guide rail oil can reduce the loss and friction between the machines, and has the functions of rust prevention, anti-oxidation, lubrication, adhesion, etc. However, during the operation of the laser processing device, the guide rail oil is easy to drip onto the base 11 and contaminate the base 11.
