The guide block 531 is mounted on a protective cover, which is correspondingly covered on the cylindrical grinding wheel 31 and the end face grinding wheel 32. The flow guide block 531 is provided with one or more water outlets, and the metal hose 532 is connected to each water outlet, thereby forming a multi-path output, improving the cooling effect and the selection of a cooling area. For example, three groups of metal hoses 532 are connected to the flow guide block 531, so that the ground surfaces of the workpieces are cooled from three angles, and the cooling effect is good.
In one embodiment, the flow splitting module 51 is mounted to the turret 10, and in particular, the flow splitting module 51 is mounted to the support column 121 with the limiting ring 122 positioned above the flow splitting module 51, such that the liquid inlet pipe 54 is connected to the flow splitting module 51 after passing through the limiting ring 122, reducing the complexity of the connection above the flow splitting module 51.
The spindle device 30 is used for processing the outer circle and the end face of a workpiece, and the spindle device 30 and the shunting module 51 are respectively located on two sides of the turret 10, so that the processing space of the spindle device 30 is prevented from being affected by a pipeline connected with the shunting module 51, and the space utilization rate is improved. Further, the distance between the splitter module 51 and the rotating device 20 is greater than the distance between the spindle device 30 and the rotating device 20. Optionally, the diversion module 51 is located above the internal grinding apparatus 40, thereby reducing the path through which the air circuit assembly 381 and the cooling water circuit 371 are connected to the internal grinding apparatus 40. The internal grinding wheel 41 of the internal grinding device 40 protrudes out of the housing 36 to avoid interference.
In one embodiment, the grinding fluid supply system 50 further comprises a recycling device provided with a magnetic separator and a circulating pump device connected to the recycling device, the circulating pump device being connected to an output pipeline of the magnetic separator. The recovery device is a grinding fluid recovery mechanism connected to the grinding machine, and grinding fluid is cooled and then gathered to the recovery device, so that the grinding fluid is recycled. The magnetic separator is arranged on the recovery device and provided with a magnetic part, and the magnetic part can be arranged into a permanent magnet or an electromagnet to adsorb metal particles mixed in the grinding fluid, so that the content of the metal particles in the grinding fluid is reduced, and the recycling rate of the grinding fluid is improved.
The circulating pump device is located at the output end of the magnetic separator and used for conveying the cutting fluid with preset pressure to the fluid inlet pipe 54 to keep the conveying pressure of the cutting fluid stable.
