Research Of Automatically Returns Situ And Optimum Design And Implementation Of Turret Oil Passage Of The MX Machine

FAW Wu xi Diesel Engine Factory Co. processing plant has an annual production capacity of 1.5 million units cylinder production line, which in the finishing section equipped with six MX processing center. In the last decade production run has been good working conditions. But the MX processing center in the long run, with varying degrees of precision hydraulic oil leakage and distortion problems have become more obvious in the near future. MX machining center as a foreign import equipment, although long-term stability has been achieved automated production, but its critical design data, technical parameters of the core technology is still the monopoly of foreign manufacturers. Principal products under warranty as factory maintenance, will not only produce high maintenance costs, the cost and the time it takes to complete will directly affect the progress of production. So the company decided to organize personnel MX machining center for independent maintenance and technological transformation. Reduce production costs, to break the monopoly of technology, to achieve self-maintenance equipment such imports of great significance.Author Now a lot of relevant information about the transmission of large machining centers, gas-liquid system, electrical control system, clear this MX machining center for transformation of four elements:Firstly, hydraulic oil leak, through the turret dispenser demolition work, analysis of the various components of the mechanism of the dispenser, and a key member site mapping, determine fault leakage from the dispenser interior fittings and be with the change due to loss.Secondly, precision machining distortion, in conjunction with the analysis of the dispenser member, found that as between pneumatic components and grating No physical isolation, since the internal parts distributor lead to loss of oil and gas working medium traverse path may lead raster foot stage failures due to pollution risk, so to propose new solutions and implement supply circuit.Meanwhile, for the oil leak as well as precision machining distortion, binding assays clamping device hydraulic circuit and found traffic monitoring hydraulic clamp circuit design flaws, making the cylinder seal aging occurs in long-term work, in repeated intake air during exercise or other elastic media, to make appear clamping cylinder in place could result in precision machining distortion. In addition, when the turret dispenser damaged due to the Grand Circle, when leakage failure, inability to timely detect the alarm causing a lot of waste oil. To solve these problems the authors propose to increase the hydraulic volume flow monitoring on the basis of the original monitoring plan and implement it.Possible personal safety and security at last, mechanic maintenance personnel manual processing centers of the bodies back into place operation. Combined with the electrical system and the NC control system analysis. Programming determine overall program and complete programming and commissioning work to ensure that the processing center in the state to achieve the maintenance of parking Auto Home function.To solve this problem to some extent on the MX processing center due to leakage of hydraulic oil contamination risks; improved monitoring of hydraulic oil, the first time when the failure to achieve a burst of alarm, ensure accuracy and efficiency; and new tools automatically back down in situ, and other functions. Reduce the risk of failure when the machine is manually operated equipment accidents caused due to misuse, improve work efficiency. Basically put an end to the maintenance personnel security risks when manually back into place to ensure safe and efficient operation of the machine MX.
