Description

Technical Field

[0001] This utility model relates to the field of mechanical assembly technology, specifically a mechanical seal assembly machine. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy, performing linear reciprocating or oscillating motion. It has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device and has no transmission backlash, resulting in smooth movement. Therefore, it is widely used in the hydraulic systems of various machines. The output force of a hydraulic cylinder is directly proportional to the effective area of ​​the piston and the pressure difference between its two sides. A hydraulic cylinder basically consists of a cylinder barrel and cylinder head, a piston and piston rod, a sealing device, a cushioning device, and a venting device. The cushioning and venting devices are optional depending on the specific application, while the other devices are essential.

[0003] When assembling a hydraulic rod, the piston rod needs to be inserted horizontally into the cylinder. However, existing equipment cannot ensure that the piston rod and the cylinder are horizontal during assembly, which causes the inner wall of the cylinder to press against the sealing ring at the end of the piston rod, resulting in damage to the sealing ring and affecting the assembly accuracy of the hydraulic rod. To solve the above problems, this application proposes a mechanical seal assembly machine. Utility Model Content

[0004] (a) Purpose of the utility model

During the assembly of the hydraulic rod, the fixed height and horizontal direction of the piston rod can be flexibly adjusted, allowing the piston rod to coincide with the center of the cylinder body. This enables the piston rod to be quickly inserted into the cylinder body, and the piston rod moves horizontally. The assembly process reduces damage to the sealing rings on the piston rod and improves the assembly accuracy of the hydraulic rod, thus solving the problems mentioned in the background art.
