Self-lubricating synchronous working cylinder

Abstract

The invention discloses a self-lubricating synchronous working air cylinder which solves the problems that an air cylinder is free of maintenance due to long-term storage and poor in synchronism. The self-lubricating synchronous working air cylinder is composed of a cylinder body, an air inlet connector, an adjusting ring, a piston rod, an end socket, a big piston, a cylinder sleeve, a small piston, a first-stage guide sleeve, a second-stage guide sleeve and the like. The air inlet connector is arranged at the left end of the cylinder body. The adjusting ring is arranged between the air inlet connector and the big piston. The big piston is connected with the cylinder sleeve and then arranged in the cylinder body. The first-stage guide sleeve is arranged at the right end of the cylinder body. The right end of the small piston is connected with the piston rod. The right end of the piston rod is connected with the end socket. The small piston and the piston rod are jointly arranged in the cylinder sleeve. The second-stage guide sleeve is arranged at the right end of the cylinder sleeve. The self-lubricating synchronous working air cylinder is good in synchronism, long in storage life, free of maintenance, good in economy, scientific in design, simple in structure, low in cost, wide in application range and capable of being widely applied to the mechanical industry with gas as power.

Description

technical field [0001] The invention relates to the technical field of cylinder design, in particular to a telescopic cylinder, in particular to a self-lubricating synchronous working cylinder. Background technique [0002] The traditional cylinder is sealed with a rubber sealing ring, which has the following disadvantages: [0003] 1) The cylinder must be inspected and repaired regularly, and long-term storage cannot be realized: the rubber sealing ring must be used in conjunction with the corresponding grease and oil, and the grease will become viscous and cracked after a certain period of storage with the cylinder, and the sealing ring will swell. The friction force of the dynamic seal increases, resulting in the failure of the piston and the like to work normally. Therefore, the cylinder must be overhauled regularly, the cylinder is disassembled, cleaned, replaced with a new sealing ring and assembled and debugged. The tedious maintenance work requires a lot of manpowe...

AI Technical Summary

Problems solved by technology

The tedious maintenance work requires a lot of manpower, material resources and time, especially for weapons and equipment, a series of problems caused by the maintenance work are particularly prominent

[0004] 2) Poor synchronization of multiple cylinders: Due to the differences between individual cylinders, for the case where multiple cylinders are required to be used synchronously and jointly, the synchronization between the cylinders during the working process is poor, and it is not suitable for occasions with high synchronization requirements
