Before he finished speaking, Zhuang Jianye had already walked to the NB-8600 five-axis CNC skin milling machine, pointed to the equipment that was processing parts, and continued to introduce: "In the past, the inner surface shape of the skin surface was relatively simple. Three-axis CNC milling machine processing.

However, the internal structure of Yun-18NB is more complicated, and the three-coordinate milling machine cannot process the internal complex grid shape very well. It needs the latest five-coordinate CNC skin milling machine to complete it.

After all, the NB-8600 five-axis CNC skin milling machine has increased the spindle speed to 10,000 revolutions per minute, and the processing speed has increased to 10 meters per minute compared to the previous three-axis 860 type. The skinning time is only half of the original CNC bed.

Not only that, the equipment also has a function, which is to integrate the performance of automatic hole making. It is well known that structural reinforcements such as stringers and shear corners must be installed in the skin to form a complete aircraft frame. Therefore, the skin must be pre-installed. Leave riveting holes.

Under normal circumstances, a skin of the mid-section fuselage of the Y-18NB transport aircraft has an average of 460 such holes. There are 17 such skins in the front and middle sections of the Y-18NB transport aircraft, requiring 7820 holes to be punched.

In order to better perform hole processing, the bottom of the machine tool is also equipped with two vacuum suction furniture, which can realize flexible tooling, and cooperate with the computer to control the processing accuracy at plus or minus 0.2mm.

In addition, due to the thermal expansion and contraction of metal, it has a great impact on the accuracy of hole making. We also integrated a set of temperature compensation functions on the NB-8600. This function can be used to accurately perform on the CNC machine tool. Control the accuracy of the skin process holes at different temperatures.

All three functions are at the leading level in the world today. "

Listening to Zhuang Jianye's introduction, the leaders and heads of leaders and military leaders all nodded in satisfaction when looking at the parts being processed on the NB-8600 five-axis CNC skin milling machine.

After introducing the NB-8600 five-axis CNC skin milling machine, Zhuang Jianye led everyone to move forward, and then pointed to another large-scale machine that was being processed, and continued to introduce: "This is the NB that our Ascendas Group has just applied. —9800 type five coordinateless CNC riveting machine.

As mentioned before, the manufacturing of large aircraft fuselage panels requires riveting the stringers, cut corners, frames and skins into small panels, or butting these panels into large panels, and the production of these panels has been used in the past. Is a semi-automatic riveting machine.

The biggest trouble of this semi-automatic riveting machine is that it needs to manually draw lines in the riveting area. This is a very technical skill. Not only does it require extremely sophisticated experience, even a little carelessness will cause extremely serious errors. The efficiency is very low, and usually it takes a week to manufacture a small three-meter-long panel.

For this reason, our Ascendas Group has developed this NB-9800 five-coordinate-free CNC riveting machine through continuous research and development. It does not require marking operations. It only needs one person to complete automatic positioning, and it can complete 10 meters in 2 days. The manufacturing of large-scale siding panels realizes the complete automation of aircraft siding manufacturing. "

If the previous NB-8600 five-coordinate CNC skin milling machine is just amazing; then the NB-9800 five-coordinate CNC riveting machine just introduced by Zhuang Jianye has completely surprised the leaders and chiefs.

Facts speak louder than words, and no matter how brilliant Zhuang Jianye is, he can't match the wishes of these leaders.

The NB-9800 five-coordinate-free CNC riveting machine is really one person up and down, and the entire equipment has a length of five meters and a height of four meters. The flexible tooling fixtures on both sides can clamp up to ten meters long siding blanks. .

The mechanical arms on both sides, an adsorbing beam, and a shearing triangle, are accurately installed in the place that needs to be fixed by the computer under the guidance of the photoelectric probe, and then the riveting head begins to slowly drop, as the booming With sound, rows of rivets accurately connect several components together.

Both stable and accurate.

The most important thing is the high efficiency!

In this way, with a sigh of three points and a surprise of seven points, the leaders and others follow Zhuang Jianye's occupation in the No. 0 workshop and continue to advance a series of automatic drilling and riveting machines such as NB-1600 sliding rail. .

NB-2800 CNC beam milling machine, NB-7500 large five-axis gantry milling machine and other equipment are all enthusiastic and fascinating.

After visiting the surrounding equipment, Zhuang Jianye led the leaders and others to an assembly station, pointed to the assembly table composed of multifunctional assembly vehicles that could change the height, length, and width at will, and said: "This is one of ours. No. assembly area, thanks to the wide application of our high-precision indoor laser measurement and positioning system and the support of supporting CNC equipment, we have upgraded the Pulse I production assembly line, which was previously only applicable to small aircraft, to include fighter jets. , Helicopter and large aircraft pulse Ⅲ production line.

The place we occupy at this moment is the No. 1 working area of ​​the Pulse III production line, which is mainly responsible for the overall assembly of the front fuselage, middle fuselage, rear fuselage, left and right wings and tail section.

Leaders, please look over there..."

As Zhuang Jianye said, he stretched his hand and pointed to a few technicians not far away who were operating portable notebook computers: "There. It is to operate the laser positioning system in front of the computer. Using this system, the accurate docking error of the fuselage can be controlled. After the plus and minus 0.25mm **** joint is smooth, the NB-1600 sliding rail type automatic drilling machine can carry out precise hole making and riveting.

It is precisely by using this method that we can confidently say that we can finally assemble an 18NB transport aircraft in three days~lightnovelpub.net~Because the station we designed is very automated and the installation efficiency is very fast, usually one worker The workload of the position is three days. After three days, all the workstations are rotated, and the cycle is repeated to form an efficient and fast assembly process like a pulse. "

The leaders and leaders in the army nodded suddenly, and then attentively watched the deserted but orderly work scene in the huge factory building.

Suddenly, the military leader’s gray eyebrows were slightly raised twice, turned around and looked around, and asked suddenly: "Xiao Zhuang, I think the aircraft produced at your workstation is not a large one. The transport plane is more like a fighter jet that has never been seen before."

"The old chief has really good eyesight. I really can’t hide anything from you. It’s not long since our No. 0 workshop has just been completed. We always use a model to check what is going on with our Pulsation III production line. Take a model and try it out. It’s not a terrific new model. It is the improved version of Real Dragon II, Real Dragon V. The features are nothing but the additional vertical take-off and landing function..."

When Zhuang Xin said this, the big leader didn’t have much at first, and only felt that it was an ordinary compliment. But after hearing that, her old eyes widened unconsciously, and her voice suddenly rose: "What did you say? VTOL fighter?"
