DETAILED DESCRIPTION

[0024] The utility model provides a five -axis laser processing machine tool, in order to make the purpose, technical scheme and effect of the utility model more clear, explicit, the following refers to the drawing and raises the embodiment to the utility model further detailed explanation, it should be understood that the specific embodiment described here is only used to explain the utility model, and is not used to limit the protection scope of the utility model.

[0025] Please refer to Figures 1-4 A five -axis laser processing machine tool, including bed 11, two interval settings on the bed 11's column 12, erects the upper saddle 13 and platform 14 of column 12, setting on the bed 11 and can slip between two columns 12's Y axle sliding table 15, be used for driving Y axle sliding table 15 front and back movement's Y axle drive mechanism, setting on Y axle sliding table 15's X axle sliding table 16, be used for driving X axle sliding table 16 left and right movement's X axle drive mechanism, setting on X axle drive mechanism's clamping table 2, the Z axle sliding table 17 of slidable setting on the upper saddle 13, be used for driving Z axle sliding table up and down movement's Z axle drive mechanism, and setting on Z axle sliding table 17's laser processing module 3, the clamping table 2 includes setting on X axle sliding table 16's cushion block 23, setting on cushion block 23's BC axle rotary table 21, and setting on C axle rotary head of BC axle rotary table 21's sleeve 22, the sleeve 22 is equipped with tool shank clamping mouth on it;The platform 14 is located in the back of upper saddle 13 and the upper surface of platform 14 is equipped with laser 4, and laser 4 generates laser and transmits to laser processing module 3 through optical path structure.

[0026] Compared with the five -axis laser processing machine tool of prior art adopts cradle type rotary table, the clamping table 2 of the five -axis laser processing machine tool of the utility model adopts the combination of BC axle rotary table 21 and sleeve 22, and laser processing module 3 will not interfere with clamping table 2, laser processing module 3 can process tool 7 at close range, can realize more flexible multi -angle clamping and adjustment to tool 7, satisfy the complex processing demand of tool 7, can better cope with the processing of various tool 7 chip breaking groove, helical groove and other complex profile and profile, and tool 7 blade edge passivation operation, improve the adaptability and flexibility of processing.The specially set tool shank clamping mouth on sleeve 22 can be matched and assembled with the tool shank of tool 7, solve the problem that existing clamp can not adapt tool 7 tool shank, ensure the stability and accuracy of tool 7 clamping, thereby improve the processing precision and quality.

[0027] The tool 7 is pre-installed on the tool holder, and then the clamping end of the tool holder is inserted into the tool holder clamping port of the collet 22. The clamping system in the collet 22 clamps and fixes the tool holder again, ensuring the safe and stable rotation of the tool 7. For example, the tool holder of the tool 7 adopts a BT50 tool holder, and the tool holder clamping port of the collet 22 is a BT50 interface. The BT50 is a standard international general-purpose clamp installation specification, which is widely used in various machining centers and numerical control machine tools. The BT50 tool holder is designed with a taper, which can realize quick and accurate positioning and clamping when used with the BT50 interface on the collet 22, reducing the time required for tool replacement and improving production efficiency. The close fit between the BT50 tool holder and the tool holder clamping port of the collet 22 ensures the high-precision positioning of the tool 7 and ensures the machining accuracy of the tool 7.

[0028] The tool 7 can move in multiple axes under the drive of the Y-axis sliding table 15, the X-axis sliding table 16, and the BC-axis rotary table 21. The laser on the upper surface of the platform 14 generates laser light, which is transmitted to the laser processing module 3 through the light path structure. The laser processing module 3 changes the position of the laser focal point under the drive of the Z-axis sliding table 17, and performs corresponding laser processing operations on the tool 7 on the clamping table 2, such as processing the chip breaking groove, helical groove, micro-edge, and hard alloy blade groove of the tool 7, and performing passivation on the edge of the tool 7.

[0029] It should be emphasized that the platform 14 is erected to a suitable height by the column 12, and the laser 4 on the platform 14 is externally open, so that the staff can easily install and fix the laser 4 while standing, making the installation, debugging, and maintenance of the laser 4 more convenient and efficient.

[0030] Specifically, the laser processing module 3 includes a box body 31, a visual positioner 32 installed downward on the box body 31, a probe measurer 33, and a three-dimensional laser scanning galvanometer 34.

[0031] The visual positioner 32 is installed downward on the box body 31 and can perform real-time visual monitoring and positioning on the processing area. Before processing, the position and attitude of the tool 7 can be quickly and accurately identified to ensure the accuracy of the starting point and processing path of the laser processing, greatly improving the processing precision. For example, when processing a tool 7 with a complex shape, the position of each part to be processed on the tool 7 can be accurately captured to avoid processing deviation.

[0032] The probe measurer 33 can accurately measure the size, shape, etc. of the tool 7. During the machining process, the machining state of the tool 7, such as size change, surface roughness, etc. can be monitored in real time, so as to timely adjust the machining parameters, and ensure the stability and consistency of the machining quality. For the machining of the tool 7 with extremely high precision requirements, such as micro blade machining, the accurate measurement function of the probe measurer 33 is crucial, which can ensure that the size and shape of the micro blade meet the design requirements.

[0033] The three-dimensional laser scanning galvanometer 34 can perform full-range three-dimensional scanning on the tool 7, and obtain detailed three-dimensional model information of the tool 7. This enables the laser machining to be accurately customized according to the actual shape and size of the tool 7, whether it is a complex spiral groove or a special groove type, high-precision machining can be achieved. For example, when machining the groove type of the carbide insert, the three-dimensional scanning data can be used to accurately control the machining path and energy distribution of the laser, and ensure the precision and surface quality of the groove type. At the same time, the application of the three-dimensional scanning galvanometer can also realize the comprehensive passivation treatment of the cutting edge of the tool 7. Through accurate scanning of the shape and angle of the cutting edge, the laser can uniformly passivate the cutting edge, and improve the service life and cutting performance of the tool 7.

[0034] It can be understood that the cooperative work of each component in the laser machining module 3 makes the whole machining process more efficient and accurate. The cooperation of the visual positioner 32 and the probe measurer 33 can quickly and accurately determine the machining position and monitor the machining state, reducing the preparation time before machining and the error adjustment time during machining. The three-dimensional laser scanning galvanometer 34 can complete the machining of complex shapes at one time, without the need for multiple adjustments of machining angle and position, greatly improving the machining efficiency.

[0035] Further, the laser machining module 3 further comprises a surface topography measurer 35. The surface topography measurer 35 can comprehensively evaluate the overall surface performance of the tool 7 after machining. In addition to roughness and texture, it can also detect whether there are defects, micro-cracks, etc. on the surface, and provide more comprehensive information for the quality detection of the tool 7. This helps to improve the comprehensive performance of the tool 7, such as cutting performance, fatigue resistance, etc. When machining the groove type of the carbide tool, it is ensured that the groove type surface quality is good, without defects and excessive wear, thereby improving the stability and reliability of the tool during cutting, and improving the overall performance of the tool 7.

[0036] In order to adjust the pitch and tilt of the upper saddle 13, a pad 51 is installed between the upper saddle 13 and the column 12. During the debugging process, the pad 51 needs to be disassembled and reassembled multiple times. When disassembling and reassembling the pad 51, the upper saddle 13 needs to be hoisted and disassembled at the same time. Since the upper saddle 13 will shake and shift after being hoisted, it is necessary to reassemble the upper saddle 13 in the future. The debugging process is cumbersome and time-consuming. For this reason, a pad 51 and a support plate 52 are installed between the two legs of the upper saddle 13 and the corresponding column 12. In the top view, the support plate 52 extends horizontally and its two ends extend outward from the legs. Each column 12 has a lifting component 53 on its left and right sides. The two lifting components 53 together lift the support plate 52 upward so that the upper saddle 13 rises and gets off the pad 51.

[0037] When it is necessary to replace the pad 51 or perform other maintenance operations, the operator manipulates the lifting assembly 53. The two lifting assemblies 53, through the support plate 52, smoothly lift one of the legs of the upper saddle 13 upwards until the leg of the upper saddle 13 is completely detached from the pad 51, creating a gap between the upper saddle 13 and the column 12, allowing the pad 51 to be removed. This allows for easy removal of the pad 51 to adjust the pitch and tilt of the upper saddle 13 without lifting or moving the entire upper saddle 13. After the pad 51 is re-processed and adjusted, it is reinstalled between the upper saddle 13 and the column 12. Finally, the lifting assembly 53 controls the upper saddle 13 to lower, causing its leg to re-contact the pad 51, completing one adjustment cycle. This simplifies the debugging process, reduces labor intensity, and improves work efficiency.

[0038] In this embodiment, see Figure 3 As shown, the lifting assembly 53 includes a fixing block 531 fixed to the side of the column 12 and a lifting screw 532 threadedly connected to the fixing block 531 and vertically upward toward the support plate 52. The combination of the fixing block 531 and the lifting screw 532 results in a simple structure. After the lifting screw 532 tightens onto the support plate 52, the weight of the upper saddle 13 and the support plate 52 is borne by the lifting screw 532. Tightening the lifting screw 532 controls the raising and lowering of the upper saddle 13. The threaded rotation of the lifting screw 532 allows for precise control of the lifting height, achieving a fine-tuning function. The combination of the fixing block 531 and the lifting screw 532 results in a simple structure. After the lifting screw 532 tightens onto the support plate 52, the weight of the upper saddle 13 and the support plate 52 is borne by the lifting screw 532. Tightening the lifting screw 532 controls the raising and lowering of the upper saddle 13. The threaded rotation of the lifting screw 532 allows for precise control of the lifting height, achieving a fine-tuning function.

[0039] To facilitate the fixing of the laser 4, the upper surface of the platform 14 is provided with multiple threaded holes 141, and the bottom of the laser 4 is provided with feet 41. Each feet 41 is pressed onto the platform 14 by a fork-shaped clamping block 42. The fork-shaped clamping block 42 is provided with a through hole 424, through which a screw 43 passes and connects to the threaded hole 141 on the platform 14. The multiple threaded holes 141 on the upper surface of the platform 14 provide multiple optional connection positions for fixing the laser 4, increasing the flexibility and adaptability of installation. Regardless of the size and shape of the laser 4, it can be fixed through the appropriate threaded hole 141 position, ensuring that it will not shift or shake during operation. The fork-shaped clamping block 42 is connected to the threaded hole 141 on the platform 14 by screws 43, which can firmly press the feet 41 onto the platform 14, further enhancing the fixing effect of the laser 4. This clamping method is simple and reliable, can withstand large external forces, and ensures that the laser 4 remains stable during machine tool operation, providing a stable light source for laser processing.

[0040] In this embodiment, see Figure 5 As shown, the laser 4 has three feet 41 at its bottom, and the lines connecting the fulcrums of the three feet 41 form a triangle. This triangular support structure formed by the three feet 41 effectively prevents the laser 4 from tilting or sliding, especially when operating on non-flat surfaces, ensuring the stability of the laser 4 throughout its operation. Distributing the weight of the laser 4 through three independent fulcrums avoids the localized overload problems that may arise from single-point or two-point support, ensuring a uniform weight distribution and reducing the risk of deformation or damage due to uneven gravity.

[0041] Preferred, see Figure 6 As shown, the fork-shaped pressure block 42 includes a long block body 421 and a C-shaped fork head 422 integrally formed on one end of the long block body 421. The bottom surface of the C-shaped fork head 422 is higher than the bottom surface of the long block body 421 to form an area 423 for the foot cup 41 to be embedded. The through hole 424 is formed on the long block body 421 and is a recessed stepped waist hole. The fork-shaped pressure block 42 can rotate around the foot cup 41 to facilitate the alignment of the through hole 424 with the threaded hole 141 on the platform 14 and the locking of the screw 43. The C-shaped fork head 422 of the fork-shaped pressure block 42 is designed to embed the foot cup 41, providing stable support and ensuring that the laser 4 can be firmly fixed on the platform 14 after installation, reducing positional displacement caused by external vibration or shaking during operation.

[0042] In this embodiment, the bed 11 is provided with two Y-axis guide rails extending forward and backward, and the Y-axis slide 15 is slidably connected to the Y-axis guide rails via a Y-axis slider; the Y-axis slide 15 is provided with two X-axis guide rails extending left and right, and the X-axis slide 16 is slidably connected to the X-axis guide rails via an X-axis slider; the upper saddle 13 is provided with two Z-axis guide rails extending up and down, and the Z-axis slide is slidably connected to the Z-axis guide rails via a Z-axis slider; the Y-axis drive mechanism, the Z-axis drive mechanism and the Z-axis drive mechanism are all linear motors.

[0043] Preferably, the top of the upper saddle body 13 is provided with a bracket 61, and a vertically downward-facing balancing cylinder 62 is provided on the bracket 61. The output end of the balancing cylinder 62 is connected to the top of the Z-axis slide. When the Z-axis slide moves up and down, the balancing cylinder 62 can balance (counteract) part of the load of the linear motor driving the Z-axis slide to move up and down, thereby reducing the power requirement of the linear motor and improving the service life of the linear motor.
