An intermittent automatic circulation lubrication system

Abstract

The invention discloses an intermittent automatic cycle lubricating system which comprises a five-way solenoid directional valve with a first exhaust port and a second exhaust port, a cylinder body and a piston. One end of a piston rod is sleeved with a flange cover, the other end of the piston rod is fixedly connected with a nut, the flange cover is embedded in the cylinder body, the outer side of the piston rod is sleeved with a spring, a gasket is fixedly arranged between the spring and the nut, the spring is fixedly arranged between the flange cover and the gasket, a second cavity is defined by the flange cover, the piston and the inner wall of the cylinder body, the second cavity is communicated with the first exhaust port, an oil suction mouth and an oil discharge channel are arranged in the cylinder body, an inlet of the oil discharge channel is communicated with a first cavity in the cylinder body, an outlet of the oil discharge channel is communicated with the second exhaust port, and the second exhaust port is communicated with a third exhaust port. The system is compact in structure, flexible and reliable in use, good in controllability, capable of being mounted in any closed space of a machine tool, especially suitable for small space on the machine tool needing to be lubricated with a small amount of lubricating oil, and also suitable for other equipment or devices needing to be lubricated with a small amount of lubricating oil.

Description

technical field [0001] The invention relates to a lubricating system, in particular to an intermittent automatic circulation lubricating system, and the lubricating system is especially suitable for lubricating a narrow space in a numerical control machine tool. Background technique [0002] In recent years, domestic high-end CNC machine tools have developed rapidly, and have made great progress in terms of function, precision, and reliability. The lubrication system is an important part of the CNC machine tool, which is of great significance to ensure the machining accuracy of the machine tool and prolong the service life of the machine tool. While the middle and high-end CNC machine tools are developing towards high precision and high speed, higher requirements are put forward for the lubrication system of machine tools. However, the traditional lubrication system of machine tools can no longer meet the needs of machine tool development. For machine tools with compact str...

Problems solved by technology

However, the traditional lubrication system of machine tools can no longer meet the needs of machine tool development. For machine tools with compact structure and narrow space, especially high-end five-axis head machine tools, the coverage of the existing lubrication system often cannot cover the narrow space on the machine tool, and it is difficult to meet other requirements. Lubrication requirements, and the problem of recycling lubricating oil has not been well resolved
