[0016] Figure 2 This is a schematic diagram of the three-dimensional structure of the utility model without the shield.
[0017] The components in the accompanying drawings are marked as follows: 1: base, 2: measuring part 1, 21: high-precision ruler, 22: slide, 3: vertical plate, 4: measuring part 2, 5: interferometer, 6: mounting base, 61: shield, 7: distance sensor, 8: bracket, 81: monitor, 9: warning light. DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] Example 1: A CNC machine tool processing detection system, such as Figure 1-2 As shown, it includes: a base 1, which firmly supports the entire system. A vertical plate 3 is vertically provided on one side of the base 1, and a measuring piece 2 is horizontally arranged on the top. A measuring piece 2 4 with the same structure is vertically installed on the front of the vertical plate 3. These two measuring components are composed of a high-precision scale plate 21 and a slide 22 with mounting holes, which are closely connected to the workpiece clamp (moving left and right) and the processing spindle (moving up and down) of the machine tool respectively. The actual displacement is tracked by the movement of the slide 22 on the high-precision scale plate 21. Two interferometers 5 are also installed on the base 1, with built-in laser straightening parts, which are responsible for monitoring the straightness and displacement accuracy in the horizontal direction (left and right toward the laser probe) and the vertical direction (vertically upward toward the laser probe). Measuring piece 1 2, measuring piece 2 4, and interferometer 5 are all connected to the equipment's control center. They not only detect data accuracy issues with the transmission system by comparing the actual moving distance with the preset value of the servo motor control system, but also use the laser interferometer 5 to accurately measure the straightness and parallelism of the workpiece clamping table and machining spindle during operation, providing the control center with comprehensive detection data, thereby achieving real-time monitoring and precision verification of the CNC machine tool processing process, ensuring efficient and stable operation of the equipment;
[0020] It should be noted that before installing the detection system, the installation positions of the measuring parts and the interferometer 5 should be flexibly designed according to the corresponding machine tool structure to ensure the effectiveness of the connection between the measuring instrument and the machine tool components during subsequent installation.
[0021] Example 2: Based on Example 1, Figure 1-2As shown, it also includes: a mounting seat 6. Specifically, one end of the high-precision scale plate 21 of measuring piece 1 2 and measuring piece 2 4 is fixed with a mounting seat 6, and these mounting seats 6 are all equipped with a sliding shield 61. One end of the shield 61 is tightly connected to the slide 22 on the same high-precision scale plate 21. The shield will shield the adjacent high-precision scale plates, so that when the slide 22 moves with the workpiece clamp or the processing spindle, the shield 61 can slide smoothly on the mounting seat 6 synchronously; this design not only forms an effective protective barrier on the high-precision scale plate, but also greatly reduces the pollution of the high-precision scale plate 21 and the measurement interference caused by the debris generated during the processing, thereby ensuring the accuracy of the measurement data and the long-term stable operation of the system.
[0022] In a preferred embodiment: Figure 1-2 As shown, it also includes: a distance sensor 7. A distance sensor 7 is provided on the base 1 and the vertical plate 3. There are two distance sensors 7 on the base 1 and the vertical plate 3. Among them, the sensors on the base 1 are respectively located on the left and right sides thereof, with the detection ends facing downward. Such a configuration can accurately monitor the position and offset of the base 1 after a period of time. At the same time, the two distance sensors 7 on the vertical plate 3 are respectively installed on both sides of its lower part, with the detection ends facing backward, to accurately monitor whether the vertical plate 3 as a whole is skewed after a period of time. The purpose of this additional distance sensor 7 is to avoid the position offset of the entire installed support component due to the influence of machine tool processing, which in turn leads to the overall misalignment of the measuring component, ensure the system's ability to capture the dynamic position of the key components of the machine tool, provide the control center with richer and more accurate feedback information, help reduce and avoid potential problems, and ensure the overall processing quality and efficiency.
[0023] In a specific embodiment: Figure 1 As shown, it also includes: a bracket 8, a bracket 8 is provided on the upper part of the vertical plate 3, a monitor 81 is installed at one end of the bracket 8, the visual probe of the detector is facing the relative center point on the base 1, and a warning light 9 is installed on the bracket 8. The warning light 9 is connected to the detection instrument signal in the system. The operation of the machine tool and the work of the detection components are monitored through the monitor 8, and the processing faults are recorded and analyzed. The online fault diagnosis method of the CNC machine tool based on the machine learning algorithm is learned to provide early warning in the future, thereby improving the reliability of the equipment use, and the system operation status is displayed through the warning light 9, which enhances the system's ability to capture and feedback the dynamic position of the key components of the machine tool. It also enables operators to quickly identify and respond to potential problems through intuitive visual means, thereby further optimizing the processing process.
