[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1:

[0034] Reference Figures 1 to 3 As shown, this utility model provides a horizontal five-axis laser processing equipment, comprising:

[0035] A frame 1, with a cantilever 3 on one side;

[0036] Laser head 7 is located below cantilever 3 and is used to cut workpieces;

[0037] The first drive mechanism 4 is mounted on the cantilever 3 and is used to drive the laser head 7 to move along the Z-axis.

[0039] The second rotating mechanism 6 is used to drive the laser head 7 to rotate around the C-axis;

[0040] The smoke extraction mechanism is located below the cantilever 3;

[0041] The second drive mechanism 8 is used to drive the workpiece to move along the X-axis;

[0042] The third drive mechanism 9 is used to drive the workpiece to move along the Y-axis.

[0043] In this embodiment, the laser head 7 is existing technology, specifically model BM109, and is connected to the laser via optical fiber. The IPG fiber laser has the following specifications: YLR-500-AC-Y14 water-cooled WC.

[0044] The workpiece can be driven to move along the X-axis by the second drive mechanism 8, and the workpiece can be driven to move along the Y-axis by the third drive mechanism 9, thereby aligning the workpiece with the laser head 7. The distance between the laser head 7 and the workpiece can be adjusted by the first drive mechanism 4, and the tilt angle of the laser head 7 can be adjusted by the first rotation mechanism 5 and the second rotation mechanism 6, realizing five-axis linkage, thereby performing drilling, texturing and cutting processing on irregular workpieces.

[0045] This invention can improve the efficiency of processing irregularly shaped workpieces, ensure the efficient completion of cutting tasks, improve the work efficiency of enterprises, and increase profits.

[0046] Furthermore, the first drive mechanism 4 includes a support frame 403, which is arranged along the Z-axis. Both sides of the support frame 403 are connected to slide rails 404 along the Z-axis. A slide plate 407 is slidably connected between the two slide rails 404. A lead screw 405 is rotatably connected to the support frame 403. One end of the lead screw 405 is shaft-connected to the output end of the motor 402. A slider 406 is threadedly connected to the lead screw 405. The slider 406 is fixedly connected to the slide plate 407. The slide plate 407 is fixedly mounted on the cantilever 3 through a support base 401.

[0047] The motor 402 drives the lead screw 405 to rotate. Through the rotation of the slider 406 and the lead screw 405, the slider 406 slides along the slide rail 404. Since the slider 406 is fixed on the cantilever 3, the support frame 403 moves along the Z-axis on the slider 406, thereby adjusting the distance between the laser head 7 and the workpiece.

[0048] Furthermore, the first rotating mechanism 5 includes a rotating motor 501 fixedly installed at the bottom of the support frame 403. The rotating motor 501 is arranged along the A-axis.

[0050] Furthermore, the second rotating mechanism 6 includes a second rotating motor 601 mounted on a fixed base 502. The second rotating motor 601 is arranged along the C-axis, and the laser head 7 is mounted on the output end of the second rotating motor 601.

[0051] The laser head 7 is driven to rotate around the C-axis by the rotary motor 601, so as to achieve full circumferential processing of the workpiece.

[0052] Furthermore, the smoke extraction mechanism includes a smoke hood 2 connected to the bottom side of the cantilever 3, and the air extraction port of the smoke hood 2 is connected to an air extraction machine through a pipe.

[0053] The exhaust fan can collect and discharge the fumes generated during processing through the fume hood 2, thus minimizing harm to the human body.

[0054] Furthermore, the third drive mechanism 9 includes a second platform 901 mounted on the frame 1. The second platform 901 is arranged along the Y-axis. Both sides of the second platform 901 are connected to slide rails 905. A slide table 904 is slidably connected between the two slide rails 905. A lead screw 902 is rotatably connected to the second platform 901. One end of the lead screw 902 is shaft-connected to the output end of a motor 906. A slider 903 is threadedly connected to the lead screw 902. The slider 903 is fixedly connected to the bottom end of the slide table 904.

[0055] The motor 3906 drives the lead screw 3902 to rotate. Under the engagement of the lead screw 3902, the slider 3903 drives the slide table 2904 to move along the slide rail 2806, thereby driving the second drive mechanism 8 to move along the Y-axis. By fixing the workpiece on the second drive mechanism 8, the workpiece is driven to move along the Y-axis.

[0056] Furthermore, the second drive mechanism 8 includes a frame 801 connected to the top of the slide table 904. The frame 801 is arranged along the X-axis. Slide rails 806 are connected to both sides of the frame 801. The slide table 804 is slidably connected between the two slide rails 806. A lead screw 802 is rotatably connected to the frame 801. One end of the lead screw 802 is shaft-connected to the output end of the motor 803. A slider 807 is threadedly connected to the lead screw 802. The slider 807 is fixedly connected to the bottom end of the slide table 804.

[0057] The motor 803 drives the lead screw 802 to rotate. The slider 807, in conjunction with the lead screw 802, drives the slide table 804 to move along the slide rail 806, thereby moving the slide table 804 along the X-axis.

[0058] Furthermore, in order to facilitate the fixing of the workpiece, a worktable 805 is fixedly connected to the top of the slide table 804, and a clamping fixture is fixedly installed on the worktable 805 for fixing the workpiece.

[0059] The horizontal five-axis laser processing equipment provided by this utility model works as follows: The clamping fixture is pre-installed and fixed on the worktable 805 by pressure plates and pressure plate bolts. The workpiece to be processed is clamped on the clamping fixture. The workpiece is aligned below the laser head 7 by the second drive mechanism 8 and the third drive mechanism 9. The distance between the laser head 7 and the workpiece is adjusted by the first drive mechanism 4. At the same time, the tilt angle of the laser head 7 is adjusted by the first rotation mechanism 5 and the second rotation mechanism 6, thereby realizing the all-round multi-dimensional cutting processing of irregular workpieces. The fumes generated during the processing are discharged through the set fume extraction mechanism. After the processing of the first workpiece is completed, the first piece is removed and its dimensions are inspected. After passing the inspection, the cutting processing of other workpieces is carried out.

[0060] Example 2:

[0061] Reference Figures 4 to 5 As shown, the difference between this embodiment and Embodiment 1 is that the clamping fixture includes a mounting base plate 10. The top of the mounting base plate 10 is provided with three sets of support components. The three sets of support components are respectively set in the middle of the mounting base plate 10 and at both ends of the mounting base plate 10. Each set of support components includes multiple fixing tubes 13. The fixing tubes 13 are fixedly connected to the top of the mounting base plate 10. A support tube 14 is slidably connected inside the fixing tube 13. The top of the support tube 14 is connected to a suction cup 15. One end of the support tube 14 is connected to a spring 11. The other end of the spring 11 is fixedly connected to the top of the mounting base plate 10. One end of the support tube 14 is connected to a PU spring tube 12. The other end of the PU spring tube 12 is connected to a vacuum pump. The PU spring tube 12 is coiled inside the spring 11 with a gap. A permanent magnet 17 is embedded in the outer wall of the support tube 14. An electromagnet 16 is embedded in the inner wall of the fixing tube 13. The permanent magnet 17 and the electromagnet 16 are correspondingly arranged.

[0062] When clamping the workpiece, the electromagnet 16 is de-energized, and the lower surface of the workpiece contacts the suction cup 15. Since the workpiece is irregularly shaped, the operator needs to press the workpiece to overcome the elastic force of the spring 11 and move it downward along the inner wall of the fixing tube 13. At the same time, the suction cup 15 is fully attached to the non-machined surface of the irregularly shaped workpiece. Then, the electromagnet 16 is energized, generating electromagnetic waves that firmly attract the permanent magnet 17 on the support tube 14 to the electromagnet 16. Then, the vacuum pump is turned on, so that the irregularly shaped workpiece is firmly attracted to the suction cup 15. At this time, the operator removes the irregularly shaped workpiece by hand, thereby achieving the fixation of the irregularly shaped workpiece. It should be noted that the PU spring tube 12 has a certain degree of elasticity, thus adapting to the movement of the support tube 14. This structural setting can realize the clamping and fixing of various irregularly shaped parts with one set of clamping fixtures, improve the versatility of clamping fixtures, avoid the need to change the clamping fixtures that are compatible with the workpiece type when changing, save time and reduce costs.
