Horizontal cylinder assembling mechanism of hydraulic oil cylinder

Abstract

The invention discloses a horizontal cylinder assembling mechanism of a hydraulic oil cylinder. The horizontal cylinder assembling mechanism comprises a cylinder pushing support provided with a pushing oil cylinder. Two tracks are laid on a foundation on the right side of the pushing oil cylinder and fixed to the foundation through track fixing devices. Two piston rod supporting trolleys used for supporting a piston rod to be assembled are arranged on the left sides of the tracks. An oil cylinder supporting trolley for supporting an oil cylinder to be assembled and a cylinder body supporting and positioning trolley are arranged on the right sides of the tracks in sequence. A supporting track is installed between the two tracks and fixedly provided with a positioning plate. The horizontal cylinder assembling mechanism is a novel guide rail type hydraulic oil cylinder horizontal cylinder assembling special device developed for solving the problem that to prevent sealing scratching in the hydraulic cylinder assembling process, assembling is difficult. The horizontal cylinder assembling mechanism is widely applied to comprehensive assembly of hydraulic cylinders which are different in diameter and length and are provided with different internal structures. According to the horizontal cylinder assembling mechanism, the hydraulic cylinder oil cylinder assembling efficiency is greatly improved, the labor intensity is relieved, and the using frequency of crown blocks is reduced.

Description

technical field [0001] The invention belongs to the technical field of production and assembly of hydraulic cylinders, in particular to a horizontal cylinder loading mechanism for hydraulic cylinders. Background technique [0002] Hydraulic cylinders are widely used in engineering practice. They are composed of basic components cylinder barrel and cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. In the assembly process, it is necessary not only to ensure the assembly accuracy, but also to avoid scratches on the surface of the piston rod during the assembly process. The traditional hydraulic cylinder assembly process needs to use driving for auxiliary assembly. This method has the following disadvantages defect: [0003] (1) The assembly process is not easy to center, and the assembly accuracy cannot be guaranteed. Due to the relatively large mass, volume and diameter of the hydraulic cylinder to be assembled, it can only be hoisted by...

AI Technical Summary

Problems solved by technology

[0003] (1) The assembly process is not easy to center, and the assembly accuracy cannot be guaranteed

Due to the relatively large mass, volume and diameter of the hydraulic cylinder to be assembled, it can only be hoisted by driving, and then centered and assembled, which will cause difficulties in the centering between the piston rod and the cylinder body, and the central axis cannot be guaranteed On the same axis, and its assembly accuracy cannot be guaranteed

[0004] (2) It is easy to scratch the outer surface of the piston rod during the assembly process. Since there is no fixed support device, it will cause collision or friction between the piston rod and other parts during the assembly process, which will cause scratches on the surface of the piston rod. Affect the quality of subsequent use

[0005] (3) Since the length, diameter and volume of different types of hydraulic cylinders are different, they cannot be used universally in the assembly process, and each assembly needs to be readjusted

The assembly process is more complicated and not easy to adjust

[0006] (4) The labor intensity in the assembly process is high and the assembly efficiency is low. The traditional assembly method can only be carried out manually, and the quality of the general cylinder is relatively large, and the manual method is labor-intensive.

[0007] The automatic assembly line of a horizontal hydraulic cylinder proposed in the application "CN 104175117 A" can only be applied to the assembly of small hydraulic cylinders, and the automatic assembly of hydraulic cylinders with large diameter, large mass and long length cannot be realized. In the application "CN 103990959 A", a horizontal cylinder loading mechanism for hydraulic cylinders cannot be guaranteed to be on the same center line due to the separation of the machine head and the tail box. There are difficulties in centering, and the height cannot be adjusted. Sliding is carried out in a chute type, and the friction force is relatively large during the assembly process, which is not convenient for assembly
