Description

Technical Field

[0001] This utility model relates to a chip removal and oil return structure for a precision machine tool, belonging to the field of machine tools. Background Technology

[0002] Machine tools use the movement of cutting tools to process workpieces that are clamped and driven to rotate or move by the spindle. Since the temperature of both the cutting tool and the workpiece is high during processing, coolant is sprayed onto them to cool them down. Generally, an oil tank is located at the bottom of the machine tool, and a circulating pump draws coolant from the oil pump and sprays it onto the cutting tool and workpiece. The coolant flows downwards into the oil tank, achieving recycling. During the processing, metal slag is generated and falls downwards with the coolant, entering the oil tank along with it. If this metal slag is not filtered out, it may damage the circulating pump, affecting coolant circulation. Furthermore, when the metal slag is drawn by the circulating pump and sprayed onto the workpiece or cutting tool with the coolant, it can easily damage the cutting tool and the processed workpiece, shortening the service life of the machine tool and reducing the processing accuracy and quality of the workpiece.

[0003] Existing technology involves installing a liquid collection tank inside the machine tool's oil tank and a filter screen at the inlet of the liquid collection tank. After the coolant and metal slag entering the oil tank are filtered once by the filter screen, the coolant flows into the liquid collection tank for recycling. However, the filtration of metal slag in the coolant is insufficient, and some metal slag particles of considerable size enter the liquid collection tank. When the coolant mixed with metal slag is recycled, it still has a negative impact on the machining accuracy of the workpiece. Summary of the Invention

[0004] The purpose of this invention is to provide a chip removal and oil return structure for precision machine tools, which solves the technical defect in the prior art where the metal slag in the collected coolant cannot be effectively removed, thus affecting the machining accuracy of the workpiece when the coolant is circulated to cool the workpiece and machine tool.

[0005] To solve the above problems, the technical solution adopted by this utility model is: a chip removal and oil return structure for a precision machine tool, including a chip removal hood and an oil tank. The chip removal hood has a front slag outlet and a side slag outlet. Metal slag generated during machine tool processing and coolant used to cool the machine tool and workpiece fall downwards onto the chip removal hood. The oil tank is located below the chip removal hood and has a liquid collection tank, a front liquid collection channel, a side liquid collection channel, and a main liquid collection channel. The front liquid collection channel and the side liquid collection channel are respectively connected to the front slag outlet and the side slag outlet. A pre-filter is installed in the front liquid collection channel and the side liquid collection channel respectively. The screen plate and side filter screen plate, the front liquid collection channel and the side liquid collection channel are all connected to one end of the main liquid collection channel. The other end of the main liquid collection channel is equipped with a main liquid collection screen plate and is connected to the liquid collection tank. At least one circulating pump is installed at the liquid collection tank. The metal chips and coolant on the chip discharge hood enter the front liquid collection channel and the side liquid collection channel from the front slag outlet and the side slag outlet, respectively. After being filtered by the front filter screen plate and the rear filter screen plate, they enter the main liquid collection channel. After being filtered again by the main liquid collection screen plate in the main liquid collection channel to remove metal chips, the coolant enters the liquid collection tank and is drawn by the circulating pump to cool the machine tool tools and workpieces.

The total liquid collection screen is set between the baffle A and the baffle C. The liquid collection tank is set between the baffle E, the baffle C, and the inner wall of the oil tank. A total connecting channel is opened at the rear end of the baffle C, which runs through both sides, to connect the total liquid collection channel and the oil collection tank.

[0007] As a further improvement of this utility model, a front chip collection frame with a hollow structure is provided in the front liquid collection channel. The metal chips and coolant discharged from the front slag outlet fall into the front chip collection frame, and the larger metal chips are filtered by the front chip collection frame. A side chip collection frame with a hollow structure is provided in the side liquid collection channel.

[0016] 2. This utility model, by setting multiple baffles inside the oil tank, divides the oil tank into corresponding liquid collection channels. On the one hand, it increases the length of the liquid collection channels, allowing sufficient time for metal slag to settle, and enabling the metal slag to be more fully filtered out and left outside the liquid collection tank inside the oil tank. On the other hand, this utility model sets up front and side liquid collection channels, so that the coolant in the chip removal hood can be discharged into the oil tank in a timely manner, avoiding the accumulation of coolant in the chip removal hood and affecting the processing of the workpiece. At the same time, it avoids the coolant circulation in the oil tank being affected by the inability to replenish the coolant in time, thereby affecting the cooling of the machine tool and workpiece.

[0020] 6. This utility model uses a pull-out method to install the front filter screen, side filter screen, and main liquid collection screen, which facilitates the installation and disassembly of the front filter screen, side filter screen, and main liquid collection screen, and also facilitates the cleaning of metal slag inside the oil tank.

[0021] 7. The structure of the chip removal hood in this utility model, with a larger upper end and a smaller lower end, makes it easier for coolant and metal slag to be collected downwards and enter the oil tank.

[0022] 8. This utility model is equipped with a liquid collection filter screen to further filter the coolant entering the liquid collection tank, thereby reducing the metal slag content in the coolant entering the liquid collection tank.
