Generally speaking, the five-axis and five-linkage machining center can realize all-round processing of all sides of the workpiece.

However, the surface of the workpiece clamped on the workbench cannot be processed, and some special workpieces need to process this surface, so the workpiece needs to be removed from the clamping position and turned over and clamped again.

In order to ensure the accuracy of repeated clamping, then it is necessary to add an additional set of mechanical devices to ensure the "positioning error of repeated clamping". An extra set of mechanisms means several more axes of motion.

Generally, these extra axes are auxiliary axes and will not participate in the cutting movement, so the name of this kind of machine tool with more than five axes is called "X-axis five-linkage machine tool" (X is greater than 5), for example, 7-axis 5-linkage machine tool, 9-axis 5-linkage machine tool

The 9-axis 5-linkage machine tool is an advanced CNC machine tool with multiple axial and linkage functions. For example, 3 linear axes, 3 rotary axes and 3 die axes enable complex multi-axis machining operations.

The 9-axis 5-linkage machine tool has the linkage function of multiple axes, and can carry out more complex process processing, such as five-axis linkage and inclined machining, which overcomes the problem that cannot be completed by traditional machine tools.

It can be used in a variety of machining processes, such as milling, cutting, boring, grinding, etc., to meet the needs of different workpiece processing.

Through linkage control, multi-axis simultaneous processing is realized, which greatly improves production efficiency and processing efficiency.

It is widely used in aerospace, automobile manufacturing, mold engineering, medical equipment and other fields, and is suitable for processing workpieces with various complex shapes.

Therefore, the 9-axis sound complicated, but in fact, compared with the 5-axis linkage, it does not add much technical difficulty, but in order to be able to process the back of the fixture, a symmetrical fixture is added.

The most difficult thing is the 5-axis linkage, which is very simple for laboratories that have accumulated experience in 4-axis linkage.

Regardless of the axes, the core is the automation control module.

The automation module control circuit has two parts, one is the real-time control CPU KT32F202M, which is used to realize multi-axis linkage. The other part is the i1 CPU, which enables human-computer interaction and issues instructions to the KT32F202M.

When developing the 4-axis simultaneous machine tool, the future multi-axis needs were taken into account, so the control module was designed with a plug-in platform. It consists of a power board, an i1 main CPU board, a linkage CPU board, a driver board, and a backplane.

Regardless of the development of multi-axis linkage machine tools in the future, the power board, i1 main CPU board, linkage CPU board and backplane remain unchanged, but a few driver boards can be added.

Each drive board has 6 drives and acquisitions, so when applying 9 axes, the number of drives can be increased to 2.

As long as the program of the i1 main CPU board is upgraded, it can meet the needs of 9-axis applications.

The platform design concept should be the latest design concept at present, and in order to maintain the advanced nature, this part is not patented.

When negotiating with the three manufacturers who purchased 4-axis machine tool technology, Zhao Ting had already explained that if the control module was provided by Longhua, Longhua would provide the subsequent version upgrade for free.

If you produce it yourself, you will need to charge for the version every time you upgrade the version.

The upgrade of the software version is mainly to collect the records of the use problem regularly, continuously optimize the control algorithm, and increase the processing routines of different devices.

This is similar to the continuous upgrading of the Windows system in later generations.

When the three manufacturers listened to Zhao Ting's introduction, they all chose to purchase the control module.

It only took one month for Li Guocheng to manually complete the small feature machine with 9 axes and 5 linkages.

If the design of this feature phone meets expectations, it can be upgraded to gyroscopes and accelerometers in the future.

At that time, a laser welding torch and a special manipulator can be installed to complete the precision operations such as automatic bonding and welding of the above-mentioned chips, which can improve product production efficiency and yield.

The volume of the whole function machine is 1200*1000*600mm, which is placed directly on the test bench.

After checking all the installation lines and interfaces to make sure that they were correct, Li Guocheng confidently pressed the start button.

During a week of testing, various machining modes were tested, and the results met the design requirements.

Li Guocheng loaded a routine of a crankshaft with a complex curved surface, put a piece of steel into the material port, and after more than an hour, a perfect crankshaft appeared in Li Guocheng's hand.

The machining accuracy is not much worse than his manual processing, but the processing efficiency is only less than one-tenth of Li Guocheng's.

Looking at the feature machine on the desktop, he was full of pride in his heart, and visited Sam's Country several times, allowing him to 'pick up' a lot of the latest technology and material formulas.

Standing on the shoulders of giants, Xiangjiang Longhua High-tech Branch has basically digested all the material formulas. With the assistance of Li Guocheng, the materials research laboratory led by Zhou Xiaojuan has reached a higher level.

Especially when it comes to tool steels and bearing steels, the performance parameters are far ahead of those of the West.

Now the main business of the rolling mill is the production of special steel, although it has long been given the formula conveyed by Li Guocheng, but the output has not been high, and the cost remains high.

After Li Guocheng returned, as an expert, he stayed in the rolling mill for more than a month, constantly optimizing the refining process, and with the assistance of mental power, the output was slowly improved.

After a month, the process and process were stabilized, and the yield of special steel increased to 89%, and the output exploded.

Therefore, in the negotiation of Longhua 4-axis machine tool technology transfer, the rolling mill was the first to stand up and support.

In terms of the cognition of the leadership of the rolling mill, it is just to make friends with Longhua Technology, in fact, in another half a year, they will find that they are the ones who take a big advantage.

Li Guocheng has informed Zhao Ting that in the future, there will be factories to purchase technology, and the transfer fee will be directly increased to 5000W.

The reason was that the previous cost accounting was inaccurate, and the R&D investment was much larger than the data approved at that time. In addition, in order to continue the development of 5-axis simultaneous machining centers, it is necessary to accumulate sufficient funds.

It is also preached that the research of machine tools in Longhua laboratory has come to a standstill, and it is necessary to accumulate sufficient research and development funds.

This operation did not scare the factories that did not cooperate, but blew up Representative Luo.

"Lao Li, this joke is a bit big, no money? You Longhua will have no money?! ”

"Hehe, Longhua's stall is too big, and the exhibition hall is a gold-swallowing beast, in order to ensure the healthy development of the main business, we have to compress the investment in other businesses."

"Big brother, rest assured, the first fee of 2000W is guaranteed to arrive in one week, and you can't stop our project."

Representative Luo was sweating profusely and offered to pay for R&D expenses.

Li Guocheng didn't expect such an unexpected gain, "Lao Luo, rest assured, as long as the funds are in place, we will start the research immediately."

"I promise to arrive in a week, Lao Li, look, do you want to start now."

"You have said so, this face must be given, rest assured, I will ask them to start research and development in a while."

Getting the desired result, Representative Luo left Building 1 satisfied.

On the way back to Building 3, when he calmed down, he always felt that Li Guocheng agreed too quickly and too easily, and a feeling of being calculated came to his heart.
