[0001] This utility model relates to the field of assembly technology, and in particular to a cylinder tie rod assembly machine. Background Technology

[0002] Currently, in the field of cylinder assembly, workers manually thread the tie rods one by one and tighten the four outer tie rods and eight nuts. This method relies on manual labor and has many drawbacks. First, it is extremely inefficient. Second, due to the variability in manual operation, the quality of the cylinders is easily inconsistent. The key reason for this problem is that the actions of assembling and tightening the outer tie rods of the cylinder are extremely cumbersome and have long been difficult to automate, resulting in a low level of automation.

[0003] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, a cylinder tie rod assembly machine is specially provided to solve the technical problems of low efficiency and unreliable quality in the current manual assembly of cylinder tie rods.
