A hydraulic cylinder assembly spreader

Abstract

The invention provides a final assembly hanger for a hydraulic oil cylinder. The final assembly hanger comprises a hanger body and a support body, wherein through holes are formed in the hanger body and the support body; the support body is in spherical fit with the hanger body; a damping member and a cylinder sleeve retainer ring are arranged at the bottom of the hanger body; the two ends of the damping member are fixedly connected with the hanger body and the cylinder sleeve retainer ring respectively; an outer cylinder retainer ring is arranged on the final assembly hanger in a matching way; the lower part of the support body has a conical structure; the damping member adopts a spiral spring or a rubber corrugated pipe; the outer cylinder retainer ring has an open elastic ferrule structure. The support body is in spherical fit with the hanger body, so that the automatic aligning effect of the support body is enhanced, the aligning amplitude is increased, force increasing caused by inclination of a cylinder sleeve as well as collision damage to an outer cylinder barrel are avoided effectively, the cylinder sleeve and a cylinder barrel assembly can be kept coaxially easily, the labor intensity of operating personnel is alleviated, the efficiency of final assembly operation is improved, and the aims of prolonging the service life of the oil cylinder and improving the safety performance are fulfilled.

Description

technical field [0001] The invention relates to the technical field of hydraulic cylinder assembly, in particular to a hydraulic cylinder assembly hanger. Background technique [0002] The final assembly of the hydraulic cylinder refers to the assembly of the cylinder and piston parts at all levels and the assembly of the outer cylinder liner after the assembly of the cylinders and piston parts is completed step by step, especially the final assembly of the hydraulic cylinder for heavy machinery. The best method is to place the assembled cylinders of all levels on the tooling stand, use lifting equipment to lift the cylinder liners, and set them on the cylinder components. The spreader used in the hoisting process is usually a combined structure of the spreader body with lifting lugs and a rotatable support, and the support mostly adopts a cylindrical or conical structure. The main defects common to these structures are: during the lifting process, it is difficult to ensure...

AI Technical Summary

Problems solved by technology

The main defects common to these structures are: during the lifting process, it is difficult to ensure the precise concentricity of the cylinder liner and the cylinder assembly. At the same time, because the support of the above-mentioned lifting device has no self-aligning function, the cylinder liner is bound to tilt during assembly.

In this case, the surface of the outer cylinder is easily strained, which will seriously affect the product quality and even cause the cylinder to be scrapped

So far, this problem has not been well resolved
