Description

Technical Field

[0001] This utility model relates to machine tool technology, and more particularly to a central oil supply and lubrication device for a milling machine tool. Background Technology

[0002] Machine tools are machines that manufacture machines, also known as mother machines. Currently, parts requiring high precision are generally processed on machine tools, which play a vital role in the modernization of the national economy. Lubricating oil is an indispensable substance in the operation of modern machine tools; therefore, most machine tools have a lubricating oil tank for storing lubricating oil. In current technology, lubricating oil is usually poured manually into the lubricating oil tank and then distributed through pressure or a delivery pump. However, when installing a transmission hose, leaks can easily occur at the hose connection, wasting lubricating oil. Furthermore, if an integrated threaded structure is used, the processing time is longer, the manufacturing process is more complex, leading to increased tank costs and hindering future sales.

[0024] like Figures 1 to 7 As shown, this utility model discloses a central oil supply and lubrication device for a milling machine tool, comprising an oil tank 1. Multiple docking components 2 are provided at the lower end of the oil tank 1. These multiple docking components 2 allow for oil supply to different positions on the machine tool, enabling the use of a single oil tank 1. This simplifies the process by requiring only an oil drain hole on the oil tank 1. The base 3, located below the oil drain hole, is then installed onto the lower end of the oil tank 1, ensuring that the docking components 2 can be securely mounted to the oil tank 1.

[0025] The docking assembly 2 includes a base 3, an oil drain pipe 4, an elastic element 5, a spring 6, a nut 7, and a blocking plate 8. The base 3 is located at the bottom of the oil tank 1, and the oil drain pipe 4 is installed in the middle of the base 3 with its upper end connected to the oil tank 1. The elastic element 5 holds the oil drain pipe 4 in the middle of the base 3, restricting its position and ensuring that the oil drain pipe 4 is pressurized towards the oil tank 1, thereby ensuring the sealing between the oil tank 1 and the oil drain pipe 4 and preventing oil leakage.

[0026] The base 3 is installed at the bottom of the oil tank 1, and the middle of the base 3 forms an installation area 9 that extends from front to back. An installation hole 10 is provided in the middle of the installation area 9, and the width of the installation hole 10 matches the width of the mounting body 19.
