Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of component sealing, in particular to a precision sealing device for mechanical equipment. Background Technique
[0002] Generally, an oil tank is provided behind a grinding machine. Some have one oil tank, and some have double oil tanks. When using a double oil tank, it can be converted to a diesel oil tank when using diesel, and can be converted to a gasoline tank when using gasoline. It can also use one oil tank to hold lubricating oil and choose to fill the oil according to needs, which is more convenient and provides more options.
[0003] The grinding machine uses a manual valve to control the delivery of lubricating oil, effectively delivering the lubricating oil to each part that needs lubrication, reducing the part consumption of the CNC grinding machine itself, and improving the service life of the machine; at the same time, the setting of the storage oil tank can collect the excess lubricating oil after lubrication for re-lubricating the fuselage, reducing waste of resources; the setting of the manual valve simplifies the operation difficulty of workers and is beneficial to the use and maintenance of the equipment.
[0004] When the existing lubricating oil tank of a grinding machine is in use, since the oil body inside the oil tank needs to increase the pressure to be delivered to each component in the grinding machine, after long-term use, when the oil body flows out of the tank body, it is easy to leak oil at the position where the pipeline contacts the tank body. Therefore, it is necessary to seal the oil outlet at the bottom of the oil tank to prevent oil leakage for the normal passage of the oil body. When sealing, since the installation of the sealing device is relatively complex, it increases the sealing difficulty at the bottom of the oil tank. Therefore, we designed a precision sealing device for mechanical equipment to increase the sealing effect of liquid leakage. Content of the Utility Model
