Problems solved by technology

This method is not only inefficient, but also the piston rod guide sleeve cannot be pushed evenly and synchronously, and improper operation is easy to get stuck in the cylinder; in addition, the annular gap between the inner hole of the cylinder and the outer circle of the piston rod is very narrow, and it is easy to hit the piston Rod or cylinder inner wall, causing damage to key parts and other issues

Abstract

The invention relates to an inner semi-ring connected oil cylinder dismantling tool, and belongs to the technical field of mechanical engineering. The tool is characterized by comprising a jack sleeve, a jack sleeve locking ring and a fastening piece, wherein the jack sleeve is mounted on a piston rod; the jack sleeve is provided with the jack sleeve locking ring; and the fastening piece for clamping is mounted on the jack sleeve locking ring. The tool has the advantages of simple structure, compact assembly, low cost, convenience in use, high dismantling efficiency, no damage to the piston rod and a cylinder barrel and the like.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, and in particular relates to a tool for dismantling an inner half-ring connection type oil cylinder. Background technique [0002] At present, the inner half-ring connection is one of the typical oil cylinder structures. This structure processes the grooves on the inner wall of the cylinder, and puts the inner snap rings (also called inner half rings) cut into three pieces into the grooves sequentially. The inner snap ring, the guide sleeve retaining ring and the shaft retaining ring realize the axial positioning of the piston rod guide sleeve. For the disassembly of the inner half-ring connection type cylinder, the piston rod guide sleeve of the cylinder port must be pushed into the cylinder barrel, so that the inner snap ring of the cylinder port and the guide sleeve stop ring are exposed, and then the guide sleeve stop ring, inner Snap ring, piston rod guide sleeve and other pa...
