[0022] Working principle: when the texture processing laser numerical control machine tool works, the workpiece is clamped on the AC turntable 3, the X-axis driving structure 22 drives the X-axis sliding saddle 21 to move forward and backward on the bed body 1, the AC turntable 3 can be adjusted in angle, so that the workpiece can move in multiple dimensions to change position, and the Y-axis driving structure 43 makes the Y-axis sliding saddle 42 move transversely on the crossbeam of the gantry 41, and the Z-axis driving structure 45 makes the Z-axis sliding saddle 44 move vertically, so that the laser box body 51 and the laser output module 52 thereon move in multiple dimensions in space to complete the processing of the workpiece surface texture. The visual camera 53 is used for monitoring and data acquisition during processing. The probe 54 adjusts the height position through the vertical telescopic structure 55, and can be flexibly adjusted in height according to the actual situation of the workpiece and laser processing when detection is needed, so as to avoid collision interference with the workpiece due to the conventional fixed position setting during complex texture processing of the laser.

[0023] The texture processing laser numerical control machine tool provided by the utility model realizes height position adjustment by installing the probe 54 on the vertical telescopic structure 55, and the probe 54 can be retracted into the laser box body 51 in a non-working state, effectively avoiding the phenomenon that the probe 54 and the workpiece collide due to the complex shape and multiple styles of the texture, and the irregular motion track of the laser in the texture processing process. The damage to the probe 54 caused by the collision interference is reduced, the detection function is avoided from being invalid, the processing cost and downtime are reduced, and the production efficiency is improved. At the same time, the problems of surface scratching of the workpiece, damage of the processing tool and precision deviation of the key components of the machine tool caused by the collision interference are prevented, the processing quality and the overall stability of the machine tool are ensured, the texture processing laser numerical control machine tool is more suitable for the special working conditions of texture processing, and the reliability and practicality of the equipment are improved.

[0024] The visual camera 53 is located in front of the laser output module 52, and the probe 54 is located beside the laser output module 52. The visual camera 53 is located in front of the laser output module 52, can accurately observe and collect data on the workpiece surface before laser processing, and obtains the initial state information of the workpiece in advance, such as surface flatness and whether there is a flaw, thereby providing an important basis for subsequent accurate processing and quality control, and helping to improve the accuracy and consistency of processing.

[0025] The probe 54 is located beside the laser output module 52, on the one hand, under the premise of not affecting the normal processing of the laser, the workpiece state and processing precision can be detected in the processing process or at a specific stage, processing information can be fed back in time, and the processing parameters can be adjusted and optimized; on the other hand, the relatively independent and reasonable layout position, combined with the vertical telescopic structure 55, further reduces the possibility of collision interference with the workpiece in the complex texture processing process, ensures the continuity and stability of processing, and reduces the downtime and production efficiency loss caused by the failure of the probe 54.

[0026] In an embodiment, as shown in Figure 2 The vertical telescopic structure 55 includes a vertically extending linear motor 551 and a support plate 552 arranged on the mover of the linear motor 551, and the support plate 552 is connected to the top of the probe 54. The linear motor 551 has the characteristics of fast response speed and high positioning accuracy. During the texture processing, when it is necessary to adjust the height of the probe 54 to adapt to different processing stages or to avoid interference with the workpiece, the linear motor 551 can quickly and accurately drive the mover to drive the support plate 552 and the probe 54 to move vertically, so as to ensure that the probe 54 can quickly reach the appropriate detection position, effectively improve the timeliness and accuracy of detection, and better guarantee the processing precision control.

[0027] In other embodiments, the driving source of the vertical telescopic structure 55 can also be a pneumatic push rod, an electric push rod, a hydraulic push rod, a screw mechanism, etc.

[0028] Preferably, the laser output module 52 is a galvanometer module, and the laser box 51 is provided with a first light path transmission element 56 connected with the light path of the galvanometer module. The galvanometer module is used as the laser output module 52, and the galvanometer has the characteristics of high speed and high precision scanning. During the texture processing, the galvanometer can quickly and accurately change the emission direction of the laser, realize efficient processing of the complex texture pattern on the surface of the workpiece, greatly improve the processing efficiency and processing precision, and meet the diversified texture processing requirements.

[0029] Further, the bottom plate of the laser box 51 is provided with a positioning pin, and the galvanometer module is provided with a positioning hole matched with the positioning pin. The positioning pin on the bottom plate of the laser box 51 cooperates with the positioning hole on the galvanometer module to play a very key role in rapid positioning. The positioning pin can be accurately inserted into the positioning hole, so that the galvanometer module can quickly find the correct position during installation, without the need for complex position calibration and debugging. This greatly shortens the replacement time of the galvanometer module, reduces the downtime of the machine tool due to replacement of the galvanometer module, and improves the overall utilization rate and production efficiency of the production equipment.

[0030] Further, the crossbeam of the portal frame 41 is provided with a support 61, and the support 61 is provided with a laser 62, and the laser 62 transmits laser to the first light path transmission element 56 in the laser box body 51 through the second light path transmission element 57. This layout can effectively utilize the space structure of the machine tool, so that the laser 62 is in a relatively high and open position, which reduces the interference of the laser 62 with the movement space of other parts of the machine tool, facilitates the flexible movement and operation of the shaft saddle, the laser box body 51 and other parts during the machining process, and guarantees the smoothness and coordination of the overall operation of the machine tool. Secondly, when the laser is transmitted between the laser 62 and the laser box body 51 through the second light path transmission element 57, the layout is beneficial to optimizing the light path design, so that the light path transmission is smoother and more stable.

[0031] Preferably, the bed body 1 is provided with a chip removal groove 11, and the chip removal groove 11 is provided with a spiral chip removal structure. During the texturing process, a large amount of cutting chips and waste materials will be generated, and the chip removal groove 11 can collect these cutting chips in time to avoid the accumulation of the cutting chips on the surface of the bed body 1. The spiral chip removal structure can efficiently transport and discharge the collected cutting chips.

[0032] The X-axis driving structure 22, the Y-axis driving structure 43 and the Z-axis driving structure 45 are all electric screw rod structures. The electric screw rod structure has good stability during movement. The cooperation between the screw rod and the nut is relatively tight and the transmission is stable. This stability enables the shaft saddle to maintain a uniform and stable state during movement, thereby ensuring that the machining track of the laser during the texturing process on the workpiece surface can be kept coherent and smooth, avoiding the problems of defects and unevenness of the machining texture caused by unstable movement, and helping to produce high-quality and uniform-appearance texture products.
