Description

Technical Field

[0001] This utility model belongs to the technical field of hydraulic cylinder production equipment, specifically relating to a hydraulic cylinder production and assembly equipment. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy, performing linear reciprocating motion (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, eliminates transmission backlash, and provides smooth movement, thus finding wide application 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 cylinders and piston rods during production, the piston rod is usually installed into the cylinder manually. For small hydraulic cylinders, manual assembly of a small number of cylinders is still feasible for workers. However, for large hydraulic cylinders and a large number of hydraulic cylinders, manual assembly alone cannot guarantee the assembly accuracy and also places a heavy burden on the workers.

[0028] Furthermore, to prevent the cylinder and piston rod from tilting, both the support mechanism 4 and the guide mechanism 5 include a second U-shaped frame 16 that cooperates with the support box 1. A telescopic rod 17 is fixedly connected to the second U-shaped frame 16. The telescopic rod 17 is preferably a hydraulic rod 7 or an electric telescopic rod 17. A support block 18 is fixedly connected to the telescopic end of the telescopic rod 17 of the support mechanism 4, and a roller 19 is fixedly connected to the telescopic end of the telescopic rod 17 of the guide mechanism 5.
