Embodiment Construction

[0012] Such as figure 1 The series gas-liquid damping cylinder shown is composed of a damping cylinder 1, two pistons 3 and an oil circuit circulation system 2. The damping cylinder 1 is divided into an oil cylinder part 1.1 and a cylinder part by a partition 6 inside it. 1.2. The two pistons 3 are respectively set in the damping cylinder 1 corresponding to the cylinder part 1.1 and the cylinder part 1.2, and the two pistons 3 are connected by the connecting rod 5 passing through the partition 6, and the connection of the connecting rod 5 can ensure The synchronous movement of the two pistons 3 makes the damping on both sides consistent and the transmission is more stable. The oil circulation system 2 is set on the damping cylinder 1 corresponding to the oil cylinder part 1.1, and the oil inlet and outlet of the oil circulation system 2 are set On the damping cylinder 1 at the two ends of the oil cylinder part 1.1, the two ends of the cylinder part 1.2 are then set as an air i...

Abstract

The invention belongs to the technical field of damping cylinders and particularly relates to a pneumatic tandem type air-liquid damping cylinder. The tandem type air-liquid damping cylinder is composed of a damping cylinder body, two pistons and an oil way circulating system, wherein the damping cylinder body is uniformly divided into an oil cylinder part and an air cylinder part by an internal partition plate; the oil way circulating system is arranged at the position, corresponding to the oil cylinder part, on the damping cylinder body; the pistons are arranged at the positions, corresponding to the oil cylinder part and the air cylinder part, in the damping cylinder body respectively and are connected through a connecting rod; a piston rod which is connected with an external device is arranged at one end of the corresponding piston of the air cylinder part; the oil inlet end and the oil outlet end of the oil way circulating system are arranged at the positions, corresponding to the two ends of the oil cylinder part, on the damping cylinder body; an air inlet and an air outlet which are connected with an external air supply device are formed in the positions, corresponding to the two ends of the air cylinder part, on the damping cylinder body. The damping cylinder is simple in structure, pneumatic driving and hydraulic damping are simultaneously carried out, the loss of energy is reduced, the transmission is more stable, the transmission speed is more uniform, and the damping cylinder is suitable for being mounted and used in a pneumatic system.

Description

technical field [0001] The invention belongs to the technical field of damping cylinders, and in particular relates to a pneumatic serial gas-liquid damping cylinder. Background technique [0002] Pneumatic actuators are required to achieve smooth feed movement in machining, but ordinary cylinder transmission is difficult to meet this requirement, so it is necessary to install a damping cylinder. The existing damping cylinder has a complex structure and is generally electromagnetically driven. Suitable for installation in pneumatic systems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pneumatically driven tandem gas-liquid damping cylinder for the above defects. The damping cylinder has simple structure, stable transmission and relatively uniform transmission speed, and is easy to install in the pneumatic system. [0004] The technical solution adopted by the present invention to solve its technical problem...
