Yangtze River Daily Great Wuhan Client News Bus No. 1 Company Warranty Branch has a pair of "good brothers": Xie Jun, the leader of the chassis minor repair group, has flexible brains and many ideas; Wang Zhengkun, the leader of the car tongs delivery group, is steady and willing to work. In the 8 years that the two teamed up, they invented and created more than ten kinds of equipment such as "lifting bench" and "internal and external bearing pulling riveter", which greatly improved the efficiency of automobile maintenance.

On March 1, in the maintenance workshop, the two people cooperated tacitly, and it took only 15 minutes to replace the cross shaft in a bus transmission shaft on the "manual hydraulic jack" they had just invented. "Replacing the cross shaft is fast, safe and successful now." Xie Jun said happily.
The drive shaft is an intermediate device that transmits the power of the engine to the rear wheels. "The cross shaft inside the drive shaft is easily damaged, and the maintenance personnel have to change three or four times a day."
Before the birth of the "manual hydraulic jack" they invented, it took 2 people half an hour to assemble the cross shaft, which was time-consuming, laborious, and "expensive". The assembly is struck by hand, and the shaft head of the cross shaft is easily broken due to uneven force. "At most, I broke 5 cross shafts, and at that time, 30 cross shafts were scrapped every month." Xie Jun calculated an account, a cross shaft of 110 yuan, so calculated, the material cost will cost nearly 40,000 yuan a year.

Can you design a device that makes the cross shaft more uniform and reduces the scrap rate? In October last year, Xie Jun and Wang Zhengkun got together again to make a fuss. This time, Operation Save the Cross Axis is the tenth collaboration between the two. Xie Jun proposed to draw drawings, and Wang Zhengkun got started to operate, find waste materials, throw and wash on various machine tools, and finally turn Xie Jun's drawings into practical and convenient tools.
Half a month later, the "manual hydraulic jack" was baked: the installation time of the cross shaft was saved by half, and the installation success rate was "one hundred and one hundred", and there was almost no scrap on the installation of the cross shaft.
"Xie Jun has many ideas, but he is impatient, and it is very suitable for Wang Zhengkun, who is willing to work with few words." Huang Hanting, secretary of the party branch of a company's warranty branch, said.
Now, the two people are still using their brains to continue to modify this manual hydraulic jack, "hoping that in the future, one person can easily replace these damaged parts." (Reporter Lei Yan Correspondent Liu Ting Bai Ziwei)
