Embodiment Construction

[0017] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0018] The installation orientations of the components in this embodiment are all subject to the accompanying drawings in the specification.

[0019] A kind of hydraulic oil cylinder piston design that prevents the damage of the cylinder barrel of the present embodiment, such as figure 1 and figure 2 As shown, it includes a cylinder 1 and a piston 2 sleeved in the cylinder 1. The piston 2 includes a piston 2 head 21 and a piston rod 9. The piston 2 head 21 is in the shape of a guide ring and is connected to the cylinder. The rod cavity is adjacent to the rod chamber, and the right end of the piston 2 head 21 is adjacent to the rodless chamber of the oil cylinder, and is provided with a boss 22;

[0020] There is a gap between the head 21 of the piston 2 and the cylinder 1; a copper sleeve 3 is ar...

Abstract

The invention provides hydraulic oil cylinder piston design capable of preventing a cylinder tube from being damaged. According to the design, the cylinder tube and a piston sleeved with the cylindertube are included, the piston comprises a piston head and a piston rod, and the piston head is in a guiding ring shape and is adjacent to a rod cavity of an oil cylinder. The right end of the piston head is adjacent to a rodless cavity of the oil cylinder and provided with a boss, a copper sleeve is arranged between the cylinder tube and the boss, the outer diameter of the copper sleeve is seamlessly attached to the cylinder tube through an O-shaped sealing ring, and the inner diameter of the copper sleeve is seamlessly attached to the boss through an O-shaped sealing ring. A thread flange isarranged at the right end of the copper sleeve, the inner diameter of the thread flange and the piston rod are fixed through a thread, and the right end of the thread flange reversely jacks the rightend face of the boss of the piston through a tightening bolt to enable the copper sleeve to be fixed to the boss. The problem that due to the self-weight of a piston, the piston rubs a cylinder tube to damage an oil cylinder is solved, meanwhile the sealing effect of the piston is ensured, and the pressure maintaining effect is achieved.

Description

technical field [0001] The invention relates to the technical field of hydraulic oil cylinders, in particular to a hydraulic oil cylinder piston design capable of preventing cylinder barrel damage. Background technique [0002] In the prior art, Y-shaped sealing rings, guide rings, and combined seals are usually used between the piston and the cylinder barrel of the hydraulic cylinder. When the oil cylinder is installed horizontally, due to the dead weight of the piston itself, the seal at the bottom end of the piston will be damaged. The self-weight compression of the piston itself causes the entire piston to shift. When the piston moves, it will rub against the cylinder, resulting in damage to the cylinder, which in turn makes the sealing effect of the piston invalid, and eventually causes damage to the cylinder. Contents of the invention [0003] The purpose of the present invention is to propose a hydraulic cylinder piston design that prevents damage to the cylinder ba...
