Description

Technical Field

[0001] This invention belongs to the field of metal processing technology, and particularly relates to an intelligent adaptive cutting device for metal processing. Background Technology

[0002] Metal cutting is a machining method that removes excess metal from a workpiece by using the relative motion between the cutting tool and the workpiece. Cutting processes are widely used in the precision machining of various metals and are fundamental to the manufacture of complex shapes and high-precision parts.

[0003] Chinese Patent Application No. CN201810159197.1 and Publication No. CN108538718B discloses a cutting device that allows the operator to easily identify the location where the load current value of the spindle, on which the cutting tool is mounted, increases during the cutting of a workpiece. The cutting device includes: a spindle driven by rotation; and a cutting tool mounted at the front end of the spindle to cut the workpiece held by a chuck table. The cutting device performs cutting along a predetermined machining line. The cutting device also includes: a load current value detection unit that detects the load current value of the spindle during cutting; and a display unit that displays the load current value detected by the load current value detection unit. The load current value of the spindle during machining (corresponding to the machining predetermined line) is displayed on the display unit.

[0004] Chinese Patent Application No. CN201810047363.9 and Publication No. CN108335976B discloses a cutting device that eliminates unnecessary removal during the dressing of a cutting tool. The cutting device comprises: a cutting assembly having a cutting tool with a cutting edge for cutting a dressing plate; an elastic wave detection sensor disposed on the cutting assembly for detecting elastic waves generated when the dressing plate is cut by the cutting tool; and a control assembly. The control assembly has a storage unit that, during dressing by cutting the dressing plate with the cutting tool, the output signal of the elastic wave detection sensor changes as the cutting tool becomes sharpened. The storage unit pre-stores the value of the output signal of the elastic wave detection sensor when the sharpening dressing is completed as a threshold. When the output signal from the elastic wave detection sensor reaches the threshold, the cutting is stopped and the dressing is terminated.

[0054] Example 3:

[0055] Please see Figure 6This embodiment provides a technical solution: a system for an intelligent adaptive cutting device and automatic positioning mechanism for metal processing, the system including a vision inspection module, a displacement detection module, an adaptive control terminal, a robotic arm, a cutting module and a positioning module.

[0056] The adaptive control terminal is a display terminal 22; the vision detection module is a camera 20; the displacement detection module is a displacement sensor; the cutting module is a cutting assembly; and the positioning module is a clamping assembly and an automatic positioning mechanism.

[0058] This embodiment uses an adaptive control terminal to intelligently control the intelligent adaptive cutting device and automatic positioning mechanism for metal processing, thereby achieving precise cutting of metal parts. This device and mechanism not only improve processing efficiency but also ensure processing accuracy, meeting the processing needs of different metal parts.

[0059] Working principle and usage process of this invention:

[0060] In use, firstly, the metal parts to be processed are placed in the through groove 12 of the square plate 10 and clamped and fixed by the clamping assembly; during the clamping process, the cylinder 14 drives the clamping plate 13 to move toward the parts, the slot 16 clamps the parts, and then the threaded rod 17 is rotated, and the fixing plate 18 at the bottom of the threaded rod 17 moves accordingly to firmly clamp the parts; during the operation of the cylinder 14, the guide rod 15 slides on the side wall of the through groove 12 to guide the movement of the clamping plate 13 and ensure stable clamping.

[0061] Then, according to the processing requirements, the position of the square plate 10 is adjusted by the automatic positioning mechanism; four hydraulic telescopic cylinders 2 are used to vertically adjust the four corners of the square plate 10 through the connecting parts and L-shaped rods 5; during the adjustment process, the displacement sensor monitors the displacement of the L-shaped rods 5 in real time and feeds the data back to the display terminal 22; the operator can observe the displacement data through the display terminal 22 and make precise adjustments to the position of the square plate 10 according to the displacement calculation formula and the displacement error compensation calculation formula to ensure cutting accuracy.

[0062] After adjusting the position, the robotic arm 7 and the cutting assembly are started to perform cutting operations. The robotic arm 7 drives the drive motor 8 and the cutting blade 9 to move to the designated position. The rotary motor 24 drives the drive motor 8 to rotate and adjust the direction. The drive motor 8 drives the cutting blade 9 to rotate and cut the metal parts. At the same time, the camera 20 observes the parts on the square plate 10 in real time to ensure that the cutting process is carried out smoothly.

[0063] After the cutting is completed, the robotic arm 7 and the cutting assembly are shut down, and the square plate 10 is reset by the automatic positioning mechanism; then, the clamping assembly is released and the processed metal parts are taken out; the waste generated during the processing is collected through the collection tank 21 for subsequent processing.

[0064] In summary, this invention achieves precise cutting of metal parts through the coordinated use of the clamping assembly, automatic positioning mechanism, robotic arm 7, and cutting assembly. This device not only improves processing efficiency but also ensures processing accuracy, meeting the processing requirements of various metal parts.

[0065] By integrating advanced sensor technology and intelligent algorithms, this invention enables the device to monitor various parameters during the cutting process in real time. These data are transmitted in real time to the adaptive control terminal, i.e., the display terminal 22, for analysis and processing. Based on the analysis results, the adaptive control terminal can quickly adjust the cutting parameters to optimize the cutting process and ensure machining quality and efficiency.

[0066] In addition, the device is highly flexible and scalable; through simple programming and parameter settings, it can adapt to the processing needs of different types and specifications of metal parts; this flexibility makes the device have broad application prospects in the field of metal processing and can meet various complex and diverse processing needs.

[0067] In summary, the intelligent adaptive cutting device and automatic positioning mechanism for metal processing provided by this invention, through the integration of advanced sensor technology, intelligent algorithms, and adaptive control strategies, achieves efficient, precise, and flexible processing of metal parts. This device not only improves processing efficiency and accuracy but also reduces processing costs, and has broad application prospects.
