Establish robots to quickly manufacture clay-type ceramic prototype processing systems, and select the appropriate tool and robot processing trajectory for the characteristics of the materials being processed. Aiming at the cutting principle of soft materials, research on the robot adding process for clay materials, find suitable processing parameters, and make high temperature ceramic prototypes that meet the requirements of melt molding technology. Through the processing experiments on clay blanks, the feasibility of the new process was verified, and some problems were also found, such as chip sticking knife, poor chip removal and collapse in the finishing process, which required us to study later. Continue to work.
The establishment of a ceramic prototype processing path. With the automotive cover ceramic prototype, its largest size (370 * 325 * 70) mm, molded parts and high quality requirements. Therefore, the ceramic prototype of the automobile cover is taken as an example to discuss the addition of the ceramic prototype, which has a typical representativeness. The robot machining path is planned based on UG CAM. When using UG, the operator can add parameter settings and modifications through the dialog box, including geometric parameters, tools, methods, and programs. First, select the machining mode and set the relevant parameters to generate the tool path. The well is then optimized by simulating the well to generate the NC code. Finally, using the conversion program NC2JBI developed by our laboratory, the code conversion from NC code to robot is realized.
There are different errors when returning to the measuring points from different directions; there is a coordinate axis direction with the smallest error in the robot trajectory, and it should be along this direction as far as possible. The result of measuring the accuracy of the robot's trajectory; the trend of the maximum and minimum errors is basically the same, but the difference between the two is about 0.01mm; when the walking speed changes, the variation of the two errors is basically the same, and does not change with the walking speed. The conversion formula of NC code and robot code is established. Considering the path along the axis with the smallest track position error and compensating the trajectory, the algorithm and CAM software for generating the optimized robot milling path code are obtained. The actual machining obtained the ceramic-type spray prototype for the melt-molding model meets the requirements of the spray, thus verifying the feasibility of the developed hardware and software and processing technology.
The application of industrial robots in the ceramic industry has become a relatively mature technology in foreign countries. Industrial robots adapt to different workpieces and molds in the glazing and over-molding, and in the upper order of the blank mold. In this way, in the work of glazing process, which has a large dust and complicated operation, it can replace manual work and improve product quality and labor productivity. The physical labor intensity of the mold turning and the blanking operation is large, and it is necessary to avoid manual operation and easy fatigue in a relatively careful operation, resulting in low efficacy and easy damage to the blank. On the other hand, because the robot can "save" the optimal glazing "curve" of many workpieces, and each call requires very simple transfer of the relevant program to the "current" operating command of the robot. Therefore, once the workpiece changes, the robot can adapt to the workpiece at the fastest speed and spray a high quality glaze. This is hard to reach.
Rapid prototyping of industrial robots is a rapidly evolving method of manufacturing prototypes and parts, but in the past decade or so, its applications have been limited to materials such as paraffin, wood, plastics and light metals. Researchers have considered a variety of robot rapid prototyping systems by considering shortening product development time, improving equipment functionality, environmental harmony and product quality. A rapid prototyping system robotic system for milling foam materials was constructed. The robot rapid prototyping system for large-scale parts has a working space of 4m*2m *2m, which can produce many large parts. A fast and flexible wooden boat model system based on dual robots was constructed. Developed a thin-walled aluminum metal forming system based on industrial robots. Researcher Shan Zhongde from the National Institute of Mechanical Science has done a lot of work on robots to quickly manufacture molds.
The terminal is used to facilitate the connection of wires. It is actually a piece of metal enclosed in insulating plastic. There are holes at both ends to insert wires. There are screws for fastening or loosening, such as two wires, sometimes Need to connect, sometimes need to be disconnected, then you can use the terminal to connect them, and can be disconnected at any time, without having to solder or twist them together, very convenient and fast.
