YH5H exhibited at the Beijing Machine Tool Show in June 2006
In 2005, Yida Riping Machine Tool Co., Ltd. (YNC) provided Dongfeng Cummins Engine Co., Ltd. with a series of production equipment for the finishing of ISBe series diesel EFI engine cylinders and cylinder heads, two of which are used to process cylinder heads. The line and cylinder line adopts network-controlled parallel line processing technology, which is the first flexible parallel line with network function designed and manufactured by China. This technology fills the domestic blank and the technical level is in domestic machine tool manufacturing. The industry is at the leading level.
The three parallel lines use a total of 10 YN5H machining center modules. The YN5H machining center is a horizontal machining center produced by YNC's latest technology introduced by NTC of Japan. It is equipped with a linear tool magazine with a capacity of 25, and a three-axis fast forward speed of 40m/min. The main shaft is lubricated with oil mist. The diameter of the main shaft bearing is 100mm, 6000r/min per minute. The maximum tool diameter and length are 250mm and 400mm respectively. The tool exchange uses a double arm robot. The tool change time is 2.7s. The machining center unit module adopts the hair sensor. Gram 18i-MB system control.
Each parallel line uses a gantry-type dual-arm manipulator to transport the workpiece above the machine. Each robot is responsible for the feeding of five machine tools. The handling capacity of the single arm of the robot is 180kg, the running speed is 80mm/min, and the speed after lifting can reach 100m per minute. The loading and unloading action of one machine can be completed within 20s. The workpiece lifting, conveying and workpiece grabbing are controlled by the servo drive and have a safety self-locking function to prevent the workpiece from falling off in the event of sudden power failure. The robot control system can randomly load and unload the machine tool according to the machining condition of each station in the processing line.
The production line for Cummins has network control functions. The Ethernet monitoring system (ET) for cylinder head and cylinder line uses the computer integrated manufacturing system configuration monitoring software of General Electric Company (GE) in the United States. The processing unit of the Nike 18i-MB system is connected, and the processing status of the equipment in the workshop can be monitored through the industrial computer in the office. At the same time, the parameters in the machining unit such as parameters and machining programs of the machine can be modified and transmitted online. It makes maintenance easier and faster. The status information of the processing unit is transmitted to the computer via Ethernet. The data can be analyzed by the data to calculate the load status of the equipment, and the pre-repair plan can be made in advance to reduce the downtime caused by the fault. Establish a database of historical faults of the equipment, and save the mechanical consumables of the equipment, all electrical components, tools, fixtures, models, manufacturer information and technical data. Reporting the corresponding data can roughly predict the demand for various consumables under mass production. Provide relevant equipment specifications, manufacturers, basic parameters, replacement cycles, etc. for spare parts, consumables and oils related to equipment, and automatically generate consumable parts replacement plan, oil change plan, etc. according to the replacement cycle, and replace parts and oil change If there is a history, statistics can be made.
The cylinder head line is composed of four automatic lines of YNX053, X054, X055 and X056. The equipment provided is the first stage equipment. The installation position is reserved for the second stage equipment in each line. The first stage of the whole line is 4min, the second stage is beat. It is 2min. The types of workpieces processed are 4 valves and 4 cylinders. The whole line has fully considered the compatibility of the two cylinder heads in the mechanical design. Each single machine has a workpiece variety identification device to identify the input workpieces. The mechanical aspect can realize the conversion processing of two kinds of workpieces without any adjustment, and the electric wire can realize the mixed processing of two kinds of workpieces. The workpiece conveyance between the lines is carried out by robots, and the workpiece buffer area is provided between the lines. The robot can feed the workpiece into the buffer area or the lowering level according to the processing condition of the lower line, and the quality of the workpiece can be performed in the buffer area. Check that another function of this buffer area is to make the processing of each line become asynchronous, which makes the processing rhythm of the whole line smoother. A workpiece printing two-dimensional code device is installed at the first feeding part of the full line, a two-dimensional code is printed for each cylinder head of the upper line, and the two-dimensional code of the workpiece is respectively read at the loading position of each line, during the processing. The status of the workpiece in each machining process can be monitored and stored in real time on the Ethernet, and the data is stored in the computer, so that the accuracy data related to the workpiece manufacturing process can be queried during the engine assembly process, and at the same time, the factory can be realized. The traceability of the engine.

YNX053 line is the automatic line of the bottom surface of the finishing cylinder head. The workpiece conveying mode is the servo drive lifting step conveying. The position of the four YN5H machining centers in the second phase is reserved, and the line beat is 2min. The YNX054 line and the YNX055 line are flexible parallel processing lines consisting of three YN5H-868 machining centers, respectively, in which two machining centers are reserved for the second phase. The YNX054 machine is equipped with a horizontal rotary clamp. The machining process is the roughing of the cylinder head race and the conduit hole and the spring seat finishing. The YNX055 machine is equipped with a clamp with horizontal and vertical flip functions, and the nozzle of the cylinder head is machined. Hole and oil supply hole. The workpiece conveying methods of these two lines are all robot type. The two-stage single-stage single-production production tempo is 11.5 min, and the line tempo is 4 min. The YNX056 line is the automatic line for the bottom hole of the cylinder head seat and the conduit hole. The workpiece conveying mode is the servo drive lifting step conveying. The position of the two YN5H machining centers for the second phase is reserved, and the line beat is 2 min. Single machine fixture with servo U-axis for hinged hole feed. The line is also equipped with an on-line inspection station to control the quality of the processing.
YNX057 cylinder processing line is a flexible parallel processing line consisting of four YN5H-868 machining centers. The workpiece conveying method is robot type. The whole line is reserved for the position of one machining center in the second phase. The single-stage production cycle is 9.5min. The whole line beat is 2.5min. The configuration and processing of the four machines are identical. They are equipped with hydraulically clamped clamps with vertical reversal. The fixtures can be used for the machining of four cylinders and six cylinders. The machining content is the roughing of the cylinder tappet holes. Finishing, a total of four processes, because the roughing and finishing are carried out on the same machining center, so the machining allowance of each sequence is uniform, which can ensure the processing precision of the tappet hole, the whole line The process capability CpK is 1.67 or more.
In the above production line, parallel processing technology, workpiece two-dimensional code recognition technology and network control and management technology are used. These advanced production and management technologies make the processing line easier to manage, and also make YNC design and manufacture level up to one. New height. YNC will continue to provide pioneering and enterprising styles, and continue to provide more advanced manufacturing equipment for the majority of machine tool users, and contribute to the development of China's equipment manufacturing industry.
