Two location of modular machine tool automation implementation

Two location of modular machine tool automation implementation newmaker welcome to e hall hall 8 machine accessories/other exhibition hall combination machine tools, machine tool machine tools for special purpose, mold engraving and milling machine, engraving machine, broaching machine,. 。 。 1. An overview of the machine is mainly composed of modular machine tool lathe bed, moving workbench, fixture, slide, drilling power head, drilling tapping screw sliding platform, tapping screw head, mobile CAM and hydraulic control system, etc, as shown in figure 1. Moving workbench and mobile and clamping fixture to complete parts, automatic processing. Slide drilling and the drilling power head, used to make the adjustment and drilling hole processing capacity. Tapping thread sliding table and attack power head, used to make the adjustment and tapping screw thread tapping screw thread was processing. The movement of the workbench ( Left, right) , clamp actions ( Clamping and relax) Sliding table, drilling hole and tapping screw thread slider move ( Forward, back) Are performed by the hydraulic system. Two slide mobile hydraulic system controlled by the slider move CAM to control, the movement of the workbench and clamping fixture and relaxation is controlled by solenoid valves. The workbench's movement and the movement of the sliding table shall be carried out in strict accordance with the timing synchronization, close coordination with the two kinds of sports, in order to improve production efficiency. 2. Working principle of the electricity system, automatic starting hydraulic pump motor M1, if machine tool parts storage in situ ( Workbench in borehole location SQ1, slide drilling in situ for SQ2 action, tapping screw slide in situ SQ3 action) , hydraulic system pressure and normal pressure relay PV, indicator HL1 on in situ. The workpiece on the workbench, press the start button SB, clamping solenoid valves YV1 electrical, hydraulic system control clamp the workpiece clamping, at the same time control CAM motor M2 electric operation. When clamping limit SQ4 action that has been clamping workpiece. Starting drilling power head motor M3, due to the CAM motor M2, corresponding hydraulic valve control CAM control make the reach sliding table drilling, drilling. When drilling sliding table arrived at the end of the drilling slide back automatically, to stop in situ, M3 to stop at the same time. Wait until slide back to drilling in situ, electromagnetic valve moves to the right table YV2 electrical, hydraulic system make workbench moves to the right, when the workbench to tapping screw location, limit switch SQ6 action, workbench to stop. Start tapping screw head motor M4 forward, tapping screw thread sliding table started forward, tapping screw thread processing. When tapping screw thread slider destination ( Dead space SQ7 action) Brake electromagnet DL electricity, tapping screw head braking. 0. 3 s after tapping screw head motor M4 inversion, tapping screw thread at the same time slider is controlled by control CAM make it automatic retreat, when tapping threads slide back to the in situ, tapping screw head motor M4, CAM just run a cycle, CAM motor M2 stop, delay after 3 s left shift solenoid valve YV 3 electric, artifacts left, to stop drilling location. Relaxation electromagnetic valve YV4 electricity, artifacts, relaxation relaxation limit SQ8 action, stop to relax. In situ indicator, processing process is complete. 3. I/O address table by a machining process requirement, the working process of sequence control, the state transition is shown in figure 2. Combination machine tools 4. The realization of the fault detection of combination machine tools in the actual operation, because of various former inmates can appear some fault, so the modular machine tool control, in addition to the normal control process, also must display diagnostic program, experience has shown that most of machine tool failure appeared on the detecting element, so on the machine set up 15 fault testing point, such as table 2 machine fault points can be divided into two cases. 5. Text display Settings and programming starting Step - Micro/Win TD200 configuration Wizard Wizard selection menu command Tools TD200 Wizard for navigation through the Wizard dialog. 1) choose to use the language is Chinese. (2) set the TD200 protect password for 1234. (3) didn't buy function key set for MO, TD200 update rate for the As fast As possible. (4) set the message length is 40 characters, the number of messages to article 15. (5) set up the address for VB40 news, news can make address for VB14, VB15 ( Trapezoidal figure out) 。 6. Conclusion above system through practical application, the effect is good, the Siemens PLC controller has a good performance, good cost performance, the use of TD200 in human-machine interface, much cheaper than using touch screen, and can realize the function of modular machine tool automation.
