Cutter head rotation adopts worm reducer, double chain transmission mode, reducer installed in the body, enhance the stability of transmission and displacement accuracy; Cutter head adopts enlarged cylinder seat, double cylinder positioning design, strong synchronization, stable and accurate positioning, while avoiding the wear of cutter head side sleeve. Rotary station (rotation station) adopts synchronous belt transmission mode, which has the advantages of fast transmission speed, high precision and low noise.
4. Feeding mechanism:
Y axis adopts one connecting plate, X axis square tube beam double rail design, after tempering treatment, on the basis of ensuring the rigidity, reduce the weight of components, more stable operation, more accurate position; Guide rail and screw are imported from Taiwan brand products, guide rail and screw assembly adopts strict scientific assembly process, the company is equipped with advanced laser collimator, laser interferometer and other testing equipment, to ensure the assembly accuracy, effectively improve the feeding accuracy and running speed. Using floating pneumatic clamp, clamping force, stable feeding; Integral dovetail drag plate, good rigidity, easy to move clamp; When feeding, the clamp can float down automatically to facilitate the plate to enter the clamp mouth, which greatly reduces the labor intensity of the operator. Multi-point automatic lubrication system is adopted for each moving part to ensure comprehensive lubrication and avoid wear of moving parts due to insufficient lubrication. All welding parts, casting parts are tempered to eliminate internal stress; Machined parts are all processed in the company (precision parts are all finished by the machining center), and assembled after passing the inspection, which effectively controls the machining tolerance of each part and eliminates the accumulated tolerance in the assembly process of parts
5. Working table:
Adopt universal ball, brush mixing, pneumatic lifting type work table, reduce the noise and vibration of machine tool working, to process the plate surface has a good protection, can effectively prevent the plate surface scratch. The unique dustproof design structure of working table can prevent the collision plate accident caused by too large gap, and play a dustproof effect on guide rail and screw; Effectively prolong the service life of guide rail and screw. Table periphery and table hairless brush part of stainless steel protection, beautiful and generous, durable, prevent plate scratch work table. Data line protection from the traditional built-in way to the fuselage side drag chain protection Settings, reduce the gap of the table, prevent scraping board, collision board.
6. Control system:
Imported motherboard superordination machine type movement control CARDS, and cooperate with panasonic servo unit RTEX bus and using full closed-loop transmission signal, to avoid the step pulse transmission way signal lost, the phenomenon such as transmission delay, and no signal feedback, improved the signal transmission speed and accuracy, can effectively enhance the speed and precision of the equipment. The communication speed of bus control mode is fast and the cycle is short, which greatly improves the accuracy of the coordination between axes in the multi-axis coordinated action. The control information is sent in the form of instruction packet, which has stronger anti-interference ability than the traditional pulse control method and can effectively avoid the influence of large power equipment on the control system. All control functions are realized through network cable transmission to avoid the workload of troubleshooting caused by too many data lines; The upper computer control system can access or write the information it needs through THE RTEX bus in time, and the obtained information can also interact with or store with the factory management system, so as to facilitate the relevant personnel to timely understand the operation dynamics and production status of the equipment; The bus connection between the host computer and the servo motor driver can make each servo motor work better.
7. Programming software:
Windows platform display, suitable for the use of general staff habits, easy to operate; Processing program graphical display, processing products at a glance, reduce the possibility of processing error; Software compatible with G code programming, CAD programming and CNCKad programming, convenient for different operators of programming habits.
