Mechanical processing by processing equipment to the metal rough parts through the material removal way, to meet the requirements of the drawing. At present, the machining of metal parts is mostly realized by metal cutting. Human factors can lead to low machining efficiency and poor accuracy consistency of parts.
With the continuous development of robot technology and the decrease of demographic dividend, automated processing units and production lines based on robots have been more and more used. It is not only limited to the more mature automobile cylinder block and cylinder head industry, at present, the processing of parts in various industries are developing towards the direction of automatic processing, including aerospace structural parts, automobile engine parts have realized automatic processing at present.
I. Automatic realization of loading and unloading of mechanical processing machine tools
The automatic realization of loading and unloading of machining machine tools mainly includes truss manipulator and joint robot. Today we are going to look at the characteristics of articulated robots.
Advantages of joint robot:
The biggest advantage of joint robot is strong flexibility, not limited by the structure of machine tools, can be applied to many machine tools. It can be used in a wide range of applications. In addition to being used in machine tool loading and unloading, joint robot can also be used in grinding, polishing, welding, assembly, handling palletizing and other fields.
Disadvantages of articulated robots:
Compared with the truss manipulator, the joint robot occupies a larger site space, and its arm span (working range) is limited. If a machine wants to increase the working range, it must be equipped with its walking shaft, so the price of joint robot is higher.
Two, the characteristics and composition of the machine man-machine automatic line
Based on robot machine and automatic line is set processing equipment automation, artifacts and automation automation, positioning of workpiece clamping, workpiece conveying automation, automation of chip removal, automatic line protection automation, workpiece and tool chain is equal to the automatic detection and automatic control of automated production systems, has good flexibility, production efficiency and precision is higher, Greatly reduce the labor intensity of operators, easy to achieve mass production. Its typical feature is the processing equipment in accordance with the established process line in turn, with robots and automatic conveying devices, other auxiliary devices and so on connected, so that it according to the prescribed procedures for automatic work.
In the automatic line, the workpiece with a certain production rhythm, according to the process sequence automatically through each station, automatically complete the predetermined processing process, and finally form qualified products.
The typical machine and automatic line is mainly composed of robots, processing equipment, process equipment, transport equipment, auxiliary equipment, control system and so on. Based on the process requirements, process, productivity requirements, automation and other factors, machine and automatic line structure and complexity is very different.
Three, the difficulties in the application of robot technology in mechanical processing
Under the background of rapid development of Chinese industry, robot technology will be more and more widely used in mechanical processing. In order to give full play to its advantages, technical personnel must have a comprehensive understanding and grasp of the problems existing in the application of robot technology in machining at the present stage, and on this basis, optimize and improve the work according to the relevant needs.
Covering a large area, high cost, but also to ensure high precision, the machine tool processing technology requirements are higher and higher. And the workpiece up and down the machine process is complex, resulting in a long processing cycle. And the use of hybrid processing robot can achieve in situ processing, the workpiece is not moving, the robot can be flexible "walk", but also can operate multiple machines at the same time, greatly improving the production efficiency. At the same time, the hybrid processing robot can also be integrated with measurement and sensing technology, which truly reflects the "wisdom" of manufacturing industry.
