fig. 2 is a partial sectional view of the spindle provided in the present embodiment.
Detailed Description
The spindle center water outlet cooling device of the present invention is further described with reference to fig. 1 to 2.
A spindle center goes out water cooling device, characterized by: comprises a rotary joint 2 and a main shaft 3;
a first channel 23 with a closed upper end and an open lower end is arranged in the rotary joint 2, an inlet 21 communicated with the first channel 23 is arranged on the side wall of the rotary joint 2, and a cooling liquid pipeline and an air blowing pipeline are connected to the inlet 21; namely, the inlet 21 is connected with a shuttle valve 9 through an oil pipe 8, one inlet 21 of the shuttle valve 9 is connected with the unclamping cylinder 1 through an air pipe, and the other inlet 21 of the shuttle valve is sequentially connected with the cloth belt filter tank 5 and the water pump 6 through oil pipes.
The main shaft 3 is internally provided with a second channel 24 which penetrates through two ends of the main shaft 3, and the second channel 24 is arranged coaxially with the main shaft 3. The lower end of the rotary joint 2 is rotatably connected to the upper end of the main shaft 3, and the first channel 23 is in butt joint with the second channel 24.
When the cooling device is used, the water pump 6 pumps cooling liquid to enter the cloth belt filtering tank, the cooling liquid enters the first channel 23 and the second channel 24 through the shuttle valve after being filtered, and finally enters the cutter arranged at the lower end of the main shaft 3, so that the cooling liquid flows to the cutting point of the cutter and a workpiece to be cooled, the cutting quality is improved, and the service life of the cutter is prolonged. When the tool changing is carried out, the cloth belt filter tank 5 stops working, the knife beating cylinder 1 starts blowing air, the air enters the shuttle valve from the air pipe, the air enters the first channel 23 and the second channel 24, dust and water drops in the first channel 23 and the second channel 24 are blown away, and finally the tool changing is carried out. In the above structure, the first channel 23 and the second channel 24 can realize ventilation and cooling liquid ventilation, and the structure is simple and the cost is reduced.
The embodiment is further configured as follows: the upper end of the second channel 24 is provided with a connecting counterbore 31, the lower end of the rotary joint 2 is provided with a connecting column 25 which is rotatably connected to the connecting counterbore 31, and the connecting column 25 is provided with a sealing ring 7. With this structure, on the basis of realizing the rotatable connection, the sealing when the first passage 23 is butted with the second passage 24 is realized, so that the air flow or the cooling liquid circulates in the first passage 23 and the second passage 24.
The embodiment is further configured as follows: the swivel joint 2 also has a plurality of overflow outlets 22 in communication with the first channel 23 in the side wall. After the overflow port is plugged with a corresponding pipeline, the cooling liquid can be led to other parts, so that the cooling effect is further improved, and the structure is simple. In particular applications, where the overflow outlet 22 is not connected to a pipe, a sealing cap or plug is provided to seal it.
