DETAILED DESCRIPTION

[0017] The following is combined with Figure 1-3 This application is described in further detail.

[0018] The present application embodiment discloses a five-axis machine tool coolant circulation device, referring to Figure 1-Figure 3 , including a collecting tank 1, a rotatable rotating shaft 2 is arranged inside the collecting tank 1, a stirring member 3 is fixedly installed outside the rotating shaft 2, a piston cylinder 6 is fixedly installed inside the collecting tank 1, a pipe 16 is fixedly installed on the upper end of the piston cylinder 6, a piston plate 17 is arranged inside the piston cylinder 6, the piston plate 17 is connected to the piston cylinder 6 through a movable structure, a No. 1 one-way valve 8 is movably inserted inside the piston cylinder 6, a water inlet 7 is opened outside the piston cylinder 6, the water inlet 7 is located between the No. 1 one-way valve 8 and the piston plate 17, and a No. 2 one-way valve 9 is movably inserted inside the water inlet 7.

[0019] The outer fixed sleeve of the rotating shaft 2 is provided with a gear 4, the inner part of the collecting tank 1 is fixedly inserted with a rack 5, the gear 4 and the rack 5 are meshed, and the outer part of the rotating shaft 2 is provided with a lifting component.

[0020] The lifting assembly includes a push block 10, a support block 12 and a second connecting plate 13. There are two groups of push blocks 10. A driving structure is arranged between the two groups of push blocks 10. The support block 12 is rotatably sleeved on the outside of the rotating shaft 2. One end of the second connecting plate 13 is rotatably connected to the support block 12, and the other end of the second connecting plate 13 is rotatably connected to the push block 10.

[0021] In this embodiment, the coolant falls into the interior of the collecting tank 1. Under the action of the push block 10, the two groups of push blocks 10 approach each other. Under the action of the support block 12, the two groups of No. 2 connecting plates 13 are driven to rotate, thereby pushing the rotating shaft 2 to move upward inside the collecting tank 1. Since the gear 4 is meshed with the rack 5, the rotating shaft 2 can rotate when moving upward. The rotating shaft 2 drives the stirring member 3 to rotate to mix the coolant inside the collecting tank 1. Under the action of the moving structure, when the piston plate 17 moves toward the direction of the No. 2 one-way valve 9, the piston plate 17 pushes the water inside the piston cylinder 6 into the interior of the pipe 16. When the piston plate 17 moves away from the No. 2 one-way valve 9, the water outside the piston cylinder 6 can enter the interior of the piston cylinder 6 through the water inlet 7. Under the action of the No. 1 one-way valve 8, the water inside the piston cylinder 6 will not flow out through the water inlet 7.

[0022] Reference Figure 2-Figure 3 The driving structure includes a threaded rod 14 and a motor 15. The threaded rod 14 is rotatably inserted into the inside of the collecting tank 1. The threaded rod 14 and the push block 10 are threadedly connected. The motor 15 is fixedly installed on the outside of the collecting tank 1. The output end of the motor 15 passes through the collecting tank 1 and extends to the inside of the collecting tank 1. The output end of the motor 15 is rotatably connected to the threaded rod 14.

[0023] The moving structure comprises a No. 1 connecting plate 11 , one end of the No. 1 connecting plate 11 is rotatably connected to the push block 10 , and the other end of the No. 1 connecting plate 11 is rotatably connected to the piston plate 17 .

[0024] Furthermore, the motor 15 is connected to an external power supply. It should be noted that the model of the motor 15 can be selected as YE2-6344-37KW, which is a prior art and is widely used in society, so no further elaboration is made. The electrical components appearing in the present application are all externally connected to a power supply and a control switch when in use. The motor 15 drives the threaded rod 14 to rotate. Since the threaded rod 14 and the push block 10 are threadedly connected, the threaded rod 14 can drive the two groups of push blocks 10 to move closer to or away from each other. When the two groups of push blocks 10 move closer to each other, under the action of the No. 1 connecting plate 11, the two groups of piston plates 17 are pulled closer to each other. When the two groups of push blocks 10 move away from each other, the No. 1 connecting plate 11 drives the two groups of piston plates 17 to move away from each other.
