Pneumatic hydraulic pull riveting system

Abstract

The invention discloses a pneumatic hydraulic pull riveting system. The system comprises a control assembly, a piston assembly, an upper shell, an oil tank, a pull gun piston assembly and a gun barrel; the control assembly is mounted on the upper portion of the piston assembly, a connecting nozzle is mounted on the control assembly, and an upper oil pipe assembly and an oil returning pipe are mounted on the control assembly; the upper oil pipe assembly and the oil returning pipe are inserted into the lower portion of the piston assembly through reserved through holes to be communicated with the oil tank; a handle gasket ring and a handle seat are mounted at the top end of the upper shell, and a handle hexagonal screw is mounted on the handle seat; a handle is welded to the lower portion of the gun barrel, the pull gun piston assembly is mounted in the gun barrel, a switch valve is arranged on the handle, and an oil nozzle and a gas nozzle which are communicated with the gun barrel are mounted at the lower end of the interior of the handle and are connected with the connecting nozzle through a pipeline; and the system is controlled by a gas path to be on and off, an oil path provides power, the size is small, output pressure is large, parts are sealed through a homemade sealing ring, output hydraulic stability is ensured, carrying and maintaining are convenient, and work efficiency is improved.

Description

technical field [0001] The invention relates to the field of hydraulic systems, in particular to a pneumatic hydraulic riveting system. Background technique [0002] At present, the existing pumps are large in mass, bulky, bulky, inconvenient to transport and carry, inflexible, inconvenient to maintain, unstable in seal, unstable in output pressure, and low in efficiency. For example, an aviation hydraulic pump is a hydraulic pump that provides hydraulic oil for the reciprocating motion of pneumatic tools through a double-acting cylinder. Its power source is 0.49MPa pressure gas, and Kunlun No. 15 aviation hydraulic oil is used as power oil. The hydraulic pump has the shortcomings of unstable output pressure and low efficiency, and it is bulky, inconvenient to use, and inflexible in use, which needs to be improved. Contents of the invention [0003] The purpose of the present invention is to provide a pneumatic hydraulic riveting system to solve the problems raised in the...
