Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machining, in particular to a turning and milling power ram of a numerical control machining center. Background Art

[0002] A numerical control vertical machining center and a numerical control vertical milling machine with a tool magazine. When the general spindle or tool is too long, the mechanical rigidity decreases, the torque is not concentrated, and it is easy to vibrate. A ram is installed on the milling machine. The ram is to ensure the mechanical rigidity and accuracy when the machine tool spindle or tool extends during machining. The existing ram is the main guiding structure during use. It is necessary to use lubricating oil to lubricate the ram, reduce the wear of the ram during work, and improve the service life.

[0003] There is a existing turning and milling power ram of a numerical control vertical machining center CN218926911U, which includes a vertical U-shaped ram body and an oil tank fixedly connected to the vertical U-shaped ram body. A plurality of oil outlet holes are arranged on the inner bottom surface of the oil tank in a polygonal shape. Oil guide grooves are arranged on multiple sides of the inner wall of the vertical U-shaped ram body. The upper end of the oil guide groove penetrates through the inner top wall of the vertical U-shaped ram body and is matched and communicated with the oil outlet hole. The oil outlet hole and the oil guide groove are both arranged in three groups. For this new type of turning and milling power ram of a numerical control vertical machining center, the lubricating oil in the oil tank is dispersed through the oil outlet holes and flows into the oil guide grooves on the inner wall of the vertical U-shaped ram body. The lubricating oil flows along the oil guide grooves to the lower end of the inside of the vertical U-shaped ram body, so that the lubricating oil can fully lubricate the inner wall of the vertical U-shaped ram body, reduce the wear of the vertical U-shaped ram body during operation, and extend its service life.

[0004] However, the lubricating oil of the existing power ram cannot be recycled after use, which will cause waste. And during use, the lubricating oil will directly slide down along the oil guide groove, resulting in insufficient lubrication, serious wear inside the ram, and reduced service life. To solve the above problems, a turning and milling power ram of a numerical control machining center is proposed. Summary of the Utility Model

[0005] According to the above existing technical problems, the utility model provides a turning and milling power ram of a numerical control machining center, which is characterized by including a ram body, an oil tank, an oil outlet, an oil baffle, a screw, a rotary handle, an oil filling port, a collection box, a filter screen, and a recovery pipe. An oil tank is arranged on the ram body, an oil outlet is arranged on the oil tank, an oil baffle is arranged at the oil outlet, a screw is arranged on the oil baffle, a rotary handle is arranged on the screw, an oil filling port is arranged on the oil tank, a collection box is arranged on the ram body, a filter screen is arranged on the collection box, and a recovery pipe is arranged on the collection box;

[0006] Further, the fuel tank is located above the ram body. An oil outlet is provided at the lower end of the fuel tank. The upper end of the oil baffle is square and the lower end is conical. The upper end of the oil baffle is located at the oil outlet, and there is a sealing ring around the upper end. The upper surface of the oil baffle is connected to the screw rod through a bearing. The screw rod is threadedly connected to the upper surface of the fuel tank. The upper end of the screw rod is fixedly connected to the rotary handle. There is a gap between each side of the bottom surface of the conical lower end of the oil baffle and the edge of the inner wall of the ram body;

[0007] Further, the collection box is located below the ram body. A filter screen is provided on the upper surface of the collection box. There is an oil return pump in the collection box, which is connected to an external controller. One end of the recovery pipe is connected to the collection box and the other end is connected to the fuel tank.

[0008] The beneficial effects of the present utility model:

[0009] The present utility model injects lubricating oil into the fuel tank through the oil injection port. When the inner wall of the ram body needs to be lubricated, the rotary handle is rotated to drive the screw rod to rotate downward and fall on the upper surface of the fuel tank, thereby driving the oil baffle to move downward. The upper end of the oil baffle slowly leaves the oil outlet. When the upper end of the oil baffle just leaves the oil outlet, the lubricating oil in the fuel tank enters the ram body along the inclined surface of the conical lower end of the oil baffle, and then through the gap between each side of the bottom surface of the conical lower end of the oil baffle and the edge of the inner wall of the ram body, so that the lubricating oil slides down along the side wall of the ram body to achieve lubrication. The falling lubricating oil passes through the filter screen and enters the collection box. Larger impurities are blocked by the filter screen. The lubricating oil re-enters the fuel tank from the recovery pipe under the action of the oil return pump in the collection box, realizing the circulation of the lubricating oil, recovering it during use, reducing waste, and at the same time making the lubricating oil closely slide along the side wall of the ram body, avoiding the situation of insufficient lubrication, reducing the internal wear of the ram, and extending the service life.
