Description

Technical Field

[0001] The utility model relates to the field of mechanical tooling, in particular to an assembly tooling for a spring cylinder. Background Art

[0002] With the development of hydraulic technology, the types of hydraulic cylinders are increasing, and the application of spring cylinders is becoming more and more frequent. Figure 1 Figure 2 The spring cylinder 5 shown includes a flange 1, a cylinder barrel 54, a piston rod 55, a spring 52 and a lower end cover 53. During assembly, the external flange 51 needs to be connected to the piston rod. During installation, the flange needs to be compressed downward along the piston rod to a certain position, and then a key is installed between the piston rod and the flange. When the flange is compressed, due to the force of the spring below, it is very inefficient to press the flange down manually, and manual operation requires at least two workers, one worker is responsible for pressing the flange down, and the other worker is responsible for installing a key or nut on the piston rod.

[0003] In order to overcome the low labor efficiency, some manufacturers have designed some tooling. The principle of the tooling is mainly to use a screw and a nut to compress the spring, and then rely on manpower to twist the nut or install the key, so the efficiency is relatively low. In addition, because the screw is unevenly stressed when the worker twists the nut, the screw is often damaged. At this time, replacing the screw wastes time and increases the cost of assembly.

[0009] A hydraulic cylinder is fixed to the upper end of the frame. The hydraulic cylinder is located directly above the press-fit position. The hydraulic cylinder push rod is connected to a gland assembly. The gland assembly is suitable for matching with the flange of the spring cylinder.
