The ups and downs of life in the Siheyuan

The next day, Li Yuan was driven away by Representative Tong early in the morning.

At Kyoto Daiichi Machine Tool Factory, Li Yuan saw the same type of CNC machine tool used for fan blade processing in a workshop.

A large group of people surrounded Representative Tong and Li Yuan and praised Li Yuan for being young and promising.

Then, everyone gathered around Representative Tong, hoping to get more orders.

A young chief instructor with simple clothes and short hair explained to Li Yuan.

After hearing about the design concept, machining accuracy and operation methods of the lathe, Li Yuan expressed his gratitude with a smile.

Then, with the puzzled look in Representative Tong's eyes and the genuine expressions of the factory leaders, Li and Yuan left the No. 1 Machine Tool Factory.

"Lao Li, what's going on? What do you mean by leaving without saying anything?"

Representative Tong had been holding back just now and did not ask his doubts in front of the people in the machine tool factory.

"Old boy, it's hard to get back. Look at their project leader. He graduated from the Workers' and Agricultural University.

Some of the technical parameters mentioned are completely incorrect.

It has been so long, but they are still competing with three-axis, and the 5-axis design concept is even more unacceptable.

The accuracy still depends on controlling the step pulse of the motor.

Calibration depends entirely on the operator's feeling. The processing accuracy of such a machine tool can reach 100um, which is also the limit of the machine tool.

If you want to reach 50um, it probably depends on the operator's touch.

The control program is a mess, how do you ask me to start?"

"Lao Li, I asked you to come out this time because I hope you can help them get these things done. You can't back down."

"Old boy, you saw it too.

Who are the people who received us today? Most of them are managers, but few are highly skilled.

With this style, how long do you think it will take me to get everything done?

Do you think, with my temper, I will get angry?

Based on their performance today, do you think there is room for improvement in the future? "

"It's precisely because of the difference that I need your help to improve!" Representative Tong couldn't help but raise his voice.

Li Yuan looked out the car window and did not answer.

After more than ten seconds, Representative Tong took a few deep breaths.

"I'm sorry, you know I'm not targeting you, it's just that I value Turbofan 8 too much and I hope it can appear in the blue sky as soon as possible."

"Old boy, time is waiting for me, I can't spend my time on them.

Originally, I wanted to wait until the policy became clearer before taking action.

However, today I changed my mind.

I want to set up my own laboratory in Kyoto, I want to recall them, and I want to design CNC machine tools myself."

Representative Tong was aroused by Li Yuan, "Old Li, you should have done this a long time ago! I'll go find Mr. Chu and ask him to run the procedures for you."

"Okay, please do everything. I'll also go find the old leader and get him to take action.

Such a two-pronged approach should have miraculous effects.”

"Okay, let's take action in the limelight."

Representative Tong sent Li Yuan home, and the driver turned around and rushed to the military compound.

After Li Yuan called home and made an appointment with Leader Xu at 10 a.m. the next day, he dived into the reverse chamber laboratory.

He had to get the prosthetic limbs prepared for Uncle Song as soon as possible, otherwise there would be no time to do this when the laboratory was up and running.

In order to rush the work, Li Yuan did not hesitate to use the inner breath. The inner breath was directly attached to the tool and began to process the required parts.

For most of the day, he completed precision machining of all the parts that had been initially processed.

The next step is assembly, which are all simple tasks for him.

The controller uses the Wukong series microcontroller, and the battery is a lithium-ion battery that Nuwa independently completed the formula.

Although this battery has various shortcomings, it is much better than the commonly used lead-acid batteries today.

Small size, high power density, fast storage and fast release.

As long as the protective circuit is designed to avoid over-storage and over-discharge, failure and fire can be avoided.

As for the collision, explosion and fire, that is impossible. It is installed into the aluminum alloy frame of the prosthetic limb, providing all-round protection without blind spots.

There are only two small hydraulic joints installed, one at the knee and the other, of course, at the ankle.

Each joint has a single-chip microcomputer WK6901 to control its respective hydraulic pump.

In order to control accurately, three sets of "myoelectric signal sensors" are used to capture the intention of muscle movement.

This is supplemented by a gyroscope, pressure sensor and acceleration sensor.

All information is transmitted to the single-chip computer WK6901 for comprehensive calculation, and then electrical signals are sent to the two joints.

According to the control electrical signal, the hydraulic pump starts to move according to the set motion curve, making the lower limbs swing, stretch, stand upright and other movements.

The reason why hydraulic joints are chosen is that the damping characteristics of hydraulics are more human-like, making control easier.

A micro interface, using the RS485 communication protocol, can modify parameters according to the specific user experience.

In the early 80s, the entire prosthesis was definitely a product of the era.

I wanted to install it for Uncle Song today, but seeing that it was already 11 o'clock at night, Li Yuan had to give up.

After locking the door and returning to the inner courtyard, Li Yuan felt warm in his heart when he saw that the light in the bedroom was still on.

The three children are usually quite sensible. As long as he is working, they will not disturb him and are already asleep now.

Back in the bedroom, Yang Ting was sewing. Although there was no shortage of these clothes at home, she still retained her past habits.

Adhering to the habit of keeping the old for three years with the new and mending for another three years.

Hearing the commotion, Yang Ting quickly put down her sewing and stood up to bring her foot wash.

"You're tired, wash your feet and relieve yourself." Yang Ting was as gentle and considerate as ever.

"How's your life at home?"

Recently, the second son of Lao Yang's family, also known as the second brother-in-law, has poor factory performance and cannot pay wages, making the family uneasy every day.

"That's it." When it came to home, Yang Ting sighed secretly.

Although it is said that she is a married daughter, she is throwing water out. But how can family love be easily separated?

Over the years, she has taken many things back for that home.

Fortunately, there are no old people in the family, otherwise, there would have been a big commotion long ago.

Therefore, not only is the Yang family very satisfied with this son-in-law, Yang Ting is also grateful from the bottom of her heart.

She quit her job for him, but she didn't regret it at all.

She was extremely satisfied that her husband was excellent at his job, capable in bed, and generous with his money.

Taking care of this family is her biggest wish now.

"Take some money and let your brother start a small business, such as a breakfast stall, a small restaurant, or selling clothes."

"That won't work. How much have we supported them over the years? My second brother is also a failure, and he is constantly manipulated by his wife.

I don’t think about how to work hard, I just revolve around my wife every day.”

Li Yuan hugged Yang Ting onto his lap and said with a smile, "I also like to hang around my wife."

Yang Ting hit Li Yuan, "You're not serious!"

But he didn't see her go down. Instead, he put his arms around Li Yuan's neck and took the initiative to kiss her.

Li Yuan ducked his head left and right and whispered: "Indecent!"

Yang Ting held Li Yuan's head with both hands, preventing him from moving, and forcefully sealed it.

I don't know how long it took, but Yang Ting's voice begging for mercy came from the room.

A storm slowly subsided.
