Tool for assembling piston rod of hydraulic oil cylinder

Abstract

The invention discloses a tool for assembling a piston rod of a hydraulic oil cylinder, and relates to the technical field of piston assembly. The tool comprises a main rack, a supporting device, a transmission device, a fastening device, a clamping structure and a central control device, wherein the main rack comprises a main rack body; the supporting device comprises a main shaft, a pressure rodand a protection plug; the pressure rod is in sliding fit with an installation hole; one end of the protection plug is connected with the upper surface of the pressure rod; the transmission device comprises a bearing seat and a lifting rod; the lifting rod is rotationally matched with a rectangular rotating groove; the bearing seat is rotationally matched with the lifting rod through a guide shaft; the clamping structure comprises first claw arms, bearing and second claw arms; and one ends of the plurality of first claw arms are all connected with the surface of a positioning shaft, and the other ends of the plurality of first claw arms are connected with one ends of the plurality of second claw arms through the two ends of the plurality of bearings. According to the tool for assembling the piston rod of the hydraulic oil cylinder, the large-weight cylinder body and rod body can be taken and used through the clamping structure and the transmission device, and the purpose of saving labor cost is achieved.

Description

technical field [0001] The invention relates to the technical field of piston assembly, in particular to a tool for assembling a piston rod of a hydraulic oil cylinder. Background technique [0002] The piston rod is a connecting part that supports the work of the piston. Most of them are used in cylinders and cylinders. The piston rod is a moving part with high technical requirements and frequent movements. For example, in hydraulic cylinders, the piston rod, Cylinder, end cover, and piston are composed of several parts. The quality of its processing will directly affect the reliability and life of the entire product. The piston rod has high requirements for processing, and its surface roughness is required to be Ra0.4~0.8 μm has strict requirements on coaxiality and wear resistance. The basic feature of oil cylinder rods is slender shaft processing, which is difficult to process and has always troubled processing personnel. Piston rods are mainly used in hydraulic pneumati...
