Description

Technical Field

[0002] With the deepening of mechanization and the refinement of specialized division of labor, in the process of industrial processing and manufacturing, a product needs to go through multiple processes to be completed. The automation level of each process is very low and the labor intensity is high. In addition, there are a large number of transportation and transfer links in the transition between different processes. In order to improve the quality of products and the efficiency of production activities, people have been committed to the development of stable and efficient automated processing, assembly and testing systems.

[0003] The existing end cover product assembly process is as follows: the required accessories are transported to the assembly site, the end cover oil filling hole is manually inspected with a high-pressure air gun, the press is manually operated to press and install the sliding bearing, the skeleton oil seal and the big end bearing are manually knocked and installed with a hammer, the big end bearing is manually drilled with a drilling machine to drill the locating pin hole, the big end bearing elastic locating pin is manually knocked and installed, the self-lubricating bearing is manually drilled with a drilling machine to drill the locating pin hole, the self-lubricating bearing elastic locating pin is manually knocked and installed, and the oil nozzle is manually installed. All of the above processes are completed by manual labor combined with a press and a drilling machine, and are purely manual operations. The conditions are simple, the process is complicated, it is easy to make mistakes, the production efficiency is low, the product quality is difficult to guarantee, and the labor intensity of the personnel is high.
