Everyone was attracted by Li Xiang's voice, and stepped forward one after another, Wang Guangtai took the lead, took the bolt in Li Xiang's hand, came to the bottom of his eyes to take a look, and after a while, nodded lightly and handed the bolt to Xu Changjian. Pen ~ fun ~ pavilion www.biquge.info

Xu Changjian took it and looked at it carefully, and sure enough, there was a thin crack on the bolt, from the bottom to the top, almost all through the entire bolt.

At this time, the young man who took the cylinder head to the three-coordinate testing room also came back, holding the disassembled cylinder head in his hand, and said a little breathlessly: "Mr. Wang, Xu Ban, just measured in the three coordinates, the parallelism of the bottom surface of the cylinder head is 0.02, which meets the process requirements, and it should not be a problem with the cylinder head." ”

Xu Changjian's face changed slightly, it seems that the cause of the water leakage is not caused by the cylinder head, as for the gasket, I also did a surface pressure test just now, and there is no problem, so the problem can only be this bolt.

Li Xiang took two steps forward and said: "It seems that because the strength of this bolt is not enough, cracks occurred during the test run, which made its net torque insufficient, which caused the water in the water cavity hole to seep into the cylinder liner, so that the engine emitted black smoke during the test run." ”

"Okay, now that the cause of the problem has been found, Xu Changjian, you can inform Luan Yunping of the technical quality test team and let him deal with it." Wang Guangtai said.

Luan Yunping is the leader of the technical quality test team, and Su Qiwen is equivalent to Su Qiwen in his position, but Luan Yunping is younger, and he has won the attention of the company's leaders, and there are faint signs of replacing Mu Zhongyue.

Wang Guangtai then turned his head to Li Xiang and said, "Young man, you are very good, not arrogant or impatient, and you can accurately analyze the problem, which is very good." ”

Li Xiang smiled slightly, and said modestly: "Mr. Wang, you have won the award, and I just made a theoretical analysis based on this phenomenon, and thanks to these masters who tested and repaired, without them, the cracked bolts would not have been found." ”

Li Xiang knew in his heart that he would have a long time to work in the future, and there would be many opportunities to deal with these front-line employees.

Sure enough, after listening to Li Xiang's words, Xu Changjian and others, who were still a little jealous and slanderous in their hearts, also had a smile on their faces, after all, it was also a very brilliant thing to be able to find out the problem in front of the big leader.

As a class leader, Xu Changjian is very clever, he can see that Wang Guangtai attaches great importance to this Li Xiang, and Li Xiang is not as arrogant as other college students, but very approachable, and he gave them all the credit for the problem analysis just now, which made him very happy.

"You're Li Gong, right? Thanks to you today, otherwise, when we find the crack on this bolt, we don't know when, it is likely to affect the machine off the assembly line. Xu Changjian said.

Li Xiang responded with a smile: "Xu Ban, you are too polite, I just came to our China Machinery Company, there are still many places to learn, and I will have to take care of Xu Ban in the future." ”

Wang Guangtai looked at Li Xiang and Xu Changjian humility to each other, was very satisfied, and said: "Okay, Xu Changjian, you arrange someone to repair this machine as soon as possible, so as not to affect the offline line; Li Xiang, you take a look in the workshop again, and I'll go back first. ”

After Wang Guangtai finished speaking, he walked away, leaving Li Xiang in the repair area of the test workshop.

"Go to someone from the assembly shop and change the bolt and screw it on." Xu Changjian arranged.

The young man who was still inspecting the cylinder head said yes and trotted to the assembly workshop.

"Li Gong, are you a college student who just arrived?" Xu Changjian took advantage of this gap to ask.

Li Xiang nodded and said: "Yes, I was just assigned to our Zhongji Company yesterday and arranged to be a technician in the processing group, and I came to assemble and test it today." ”

After hearing this, Xu Changjian said with a smile: "Then I will ask Li Gongduo for instructions." ”

After hearing this, Li Xiang waved his hand again and again, and said: "Xu Ban, are you kidding, I studied mechanical design and manufacturing, and I came to you mainly to study." I hope Xu Ban won't trouble me in the future. ”

"How so? It's too late for us to welcome it. Xu Changjian said.

After experiencing the engine leakage incident, the relationship between Li Xiang and the employees of the repair class in the test workshop has become much closer, which is rare among newly hired college students.

Generally, college students who have just joined the company are either condescending, feel that they are superior, and are aggressive in speaking and doing things; Either that, in front of the computer, I don't know what to do.

Only Li Xiang, in less than two days, the body processing workshop, assembly workshop, test workshop, and fitter workshop, almost all front-line operators know Li Xiang, a young man who has just come to the company, and his impression is not bad.

Just when Li Xiang and Xu Changjian were chatting, the operator of the assembly workshop finally came, holding a torque wrench and a bolt in his hand, and walked to the engine that had been disassembled.

This operator Li Xiang knew that when he looked at the assembly workshop just now, Li Xiang knew him, his name was Qian Xiaoliang, and he was the operator of the cylinder head installation process.

I saw that he was very skillful in putting the cylinder head and bolts, picking up the torque wrench in his hand, adjusting the torque required by the process, and closing them one by one.

"Xiaoliang, when you go back to close it later, you must take a look at the bolts, I suspect that there is a problem with this batch of bolts." Li Xiang said.

Qian Xiao nodded and said, "No problem, Li Gong." There's nothing to do with me here, so I'll go back to work first. ”

Then, Xu Changjian beckoned the people in the class, reinstalled the disassembled engine, and hoisted it into the test platform for a second test run.

When the engine started running, everyone stared closely, for fear of another water leakage, but fortunately, until the test was completed, there was no water leakage.

Li Xiang took out his mobile phone to check the time, and estimated that his online measurement tooling was almost ready, so he said hello to Xu Changjian and went to the fitter workshop.

When he came to the fitter workshop, Li Xiang happened to see the fitter master Zhang Dongxu stop the machine tool, so he stepped forward and asked, "Master Zhang, is my tooling ready?" ”

Zhang Dongxu looked up and said with a smile: "Yes, it's just done, it's really time for you to come." It's all there, go and see. ”

Li Xiang walked to the place where the tooling was placed, and saw that there were all kinds of tooling on the ground, Li Xiang was very happy, and thanked Zhang Dongxu repeatedly.

Zhang Dongxu didn't have much of a fight, waved his hand and said: "Okay, you can bring them all back, try it online, if it's not suitable, I'll bring it over and change it for you." ”

Li Xiang nodded, took a cardboard box, put all the tooling in it, and carried it to the machine body processing workshop.

Li Xiang was not only happy at this time, but also had a sense of accomplishment, after all, this was also the first project that Li Xiang had personally completed after stepping into the job.

Compared with those newcomers who are still familiar with their jobs, Li Xiang already has his own achievements.
