[0031] To better understand the technical solutions and beneficial effects of this disclosure, the following further describes this disclosure in detail with specific embodiments:

[0032] As Figures 1 to 5 shown, a spray cooling device 10 in an embodiment includes a power assembly 100, a flow splitting assembly 200 and two cooling assemblies 300. The power assembly 100 includes a mounting seat 110 and a driving member 120. The driving member 120 is fixedly installed on the mounting seat 110. The flow splitting assembly 200 includes a main pipe 210 and a flow splitting switch 220. The flow splitting switch 220 includes a main flow inlet 221 and two flow splitting outlets 222. One end of the main pipe 210 communicates with an external water source, and the other end of the main pipe 210 communicates with the main flow inlet 221. Each cooling assembly 300 includes a flow splitting pipe 310, a bearing seat 320 and a rotating shaft 330. One end of the flow splitting pipe 310 communicates with one of the flow splitting outlets 222. The bearing seat 320 is fixedly installed on the mounting seat 110. The rotating shaft 330 is rotatably sleeved in the bearing seat 320. One end of the rotating shaft 330 is connected to the driving end of the driving member 120, and the other end of the rotating shaft 330 is used to connect a cutting blade 20. A cooling channel 331 is formed inside the rotating shaft 330. The cooling channel 331 is distributed along the direction from the bearing seat 320 to the cutting blade 20. The rotating shaft 330 is provided with a water injection port 330a communicating with the cooling channel 331. The bearing seat 320 is provided with a connection port 321 communicating with the water injection port 330a. The connection port 321 communicates with the other end of the flow splitting pipe 310. A pressurizing impeller structure is formed in the cooling channel 331. A plurality of groove-shaped holes 332 are formed on one side of the rotating shaft 330 close to the cutting blade 20. Each groove-shaped hole 332 communicates with the cooling channel 331.

[0033] It can be understood that since the flow splitting switch 220 includes a main flow inlet 221 and two flow splitting outlets 222, one end of the main pipeline 210 is connected to an external water source, the main flow inlet 221 is connected to the other end of the main pipeline 210, and the two flow splitting outlets 222 are respectively connected to a flow splitting pipeline 310, which ensures that the flow splitting switch 220 can control different flow directions of the external water source through the switches of their respective pipelines. Moreover, the flow splitting pipeline 310 allows the external water source to flow through the cooling channel 331 of the rotating shaft 330 to the cutting blade 20, so as to achieve the cooling effect of the cutting blade 20 at different installation positions. The present disclosure adopts the opening and closing of the flow splitting switch 220, and does not require adjusting the positions of the main pipeline 210 and the flow splitting pipeline 310 to spray the cutting blade 20, realizing the convenience of the operation of cooling the cutting blade 20.

[0034] It can also be understood that since the inside of the rotating shaft 330 has a cooling channel 331, the cooling channel 331 is distributed along the direction from the bearing seat 320 to the cutting blade 20. The rotating shaft 330 is provided with a water injection port 330a communicating with the cooling channel 331, the bearing seat 320 is provided with a connection port 321 communicating with the water injection port 330a, and the connection port 321 is connected to the flow splitting pipeline 310. When the external water source flows in, it sequentially passes through the main pipeline 210, the flow splitting pipeline 310, the bearing seat 320 and the cooling channel 331, and finally reaches the cutting blade 20, realizing the cooling effect when the cutting blade 20 works. Also, since a pressurizing impeller structure is formed in the cooling channel 331, when the rotating shaft 330 rotates, the external water source passing through the cooling channel 331 increases the water supply pressure of the external water source passing through the cooling channel 331 under the action of the rotating force, improving the water supply effect to the cutting blade 20, thereby ensuring a better cooling effect. Moreover, a plurality of groove-shaped holes 332 are formed on the surface of the rotating shaft 330 close to the cutting blade 20, ensuring that the external water source flows into the end face of the cutting blade 20 through the groove-shaped holes 332 and is sprayed onto the entire cutting blade 20 under the action of centrifugal force, thereby realizing the cooling effect of the cutting blade 20. In this embodiment, the bearing seat 320 and the rotating shaft 330 are connected by a bearing. The outer ring of the bearing is fixedly installed in the bearing seat 320, and the rotating shaft 330 is rotatably sleeved on the inner ring of the bearing.

[0035] As Figures 3 to 5 shown, in one of the embodiments, the pressurizing impeller structure includes a plurality of blades 333. The plurality of blades 333 are arranged in the cooling channel 331, and a water inlet groove 334 is formed between every two blades 333. Each water inlet groove 334 communicates with the cooling channel 331. The blades 333 are used to increase the water supply pressure when the external water source flows into the water inlet groove 334 under the rotation of the rotating shaft 330, ensuring that the blades 333 drive the external water source to be drawn into the cooling channel 331 from the water inlet groove 334, so that the external water source can be timely delivered to the cutting blade 20 through the cooling channel 331 to achieve the effect of timely cooling the cutting blade 20.

[0036] As Figures 1 to 3 shown, in one embodiment, the spray cooling device 10 further includes a filter 400. Both ends of the filter 400 are respectively connected to the main pipe 210 and the external pipe. In this embodiment, by adding the filter 400, when the external water source enters the main pipe 210, sundries such as sediment are prevented from entering the cooling channel 331, avoiding the situation of blockage of the cooling channel 331.

[0037] In one embodiment, the filter 400 is a Y-type filter. The Y-type filter can effectively filter solid particles and sand grains and other sundries in the fluid, avoid pipeline blockage and damage, and thus extend the service life of the spray cooling device 10.

[0038] As Figure 1 and Figure 2 shown, in one embodiment, the spray cooling device 10 further includes an electromagnetic water valve 500. Both ends of the electromagnetic water valve 500 are respectively connected to the main pipe 210 and one end of the filter 400, and the other end of the filter 400 is connected to the external pipe. In this embodiment, by changing the opening degree of the electromagnetic water valve 500, the flow rate of the water source is adjusted to ensure that the water source is sufficient when it enters the main pipe 210, so as to achieve a good cooling effect of the spray cooling device 10.

[0039] In one embodiment, the spray cooling device 10 further includes a plurality of flow control valves (not shown in the figure). Each flow dividing pipe 310 is provided with a flow control valve. The added flow control valve adjusts the flow area of each flow dividing pipe 310 by changing the opening degree of the valve, so as to adjust the speed and flow rate of the water source passing through, so as to achieve a good cooling effect of the spray cooling device 10.

[0040] As Figure 1 and Figure 2 shown, in one embodiment, the spray cooling device 10 further includes a main ball valve 600. The main ball valve 600 is arranged on the main pipe 210 and is used to control the external water source to flow into the flow dividing switch 220. The main ball valve 600 serves as the main switch for the external water source to enter the spray cooling device 10.

[0041] As Figure 1 and Figure 2As shown, in one embodiment, the driving member 120 further includes a coupling 121, a speed reducer 122, and a driving motor (not shown in the figure). The speed reducer 122 and the driving motor are both fixedly installed on the mounting seat 110. The driving end of the driving motor is connected to the input end of the speed reducer 122, the output end of the speed reducer 122 is connected to one end of the coupling 121, and the other end of the coupling 121 is connected to the rotating shaft 330. In this embodiment, the power output by the driving motor is transmitted to the input shaft of the speed reducer 122, then transmitted to the coupling 121 through the output shaft of the speed reducer 122, and the coupling 121 transmits the torque to the rotating shaft 330, which can effectively transmit the rotational power of the driving motor to the rotating shaft 330 and ensure the stability of power transmission.

[0042] In one embodiment, the spray cooling device 10 further includes a sealing ring (not shown in the figure). The sealing ring is disposed between the rotating shaft 330 and the bearing seat 320 to ensure the sealing of the rotating shaft 330 in the bearing seat 320, prevent moisture from seeping out, and thus improve the cooling effect of the spray cooling device 10.

[0043] As Figure 1 and Figure 2 shown, in one embodiment, the spray cooling device 10 further includes a plug 700. The plug 700 is detachably disposed at the side end of the rotating shaft 330 and is used to prevent the cooling water source from seeping out from the side end of the rotating shaft 330 when the external water source flows into the rotating shaft 330.

[0044] The present disclosure also provides an engineering cutting machine, including the spray cooling device 10 described in any of the above embodiments.

[0045] Compared with the prior art, the present disclosure has at least the following advantages:

[0046] 1) In the spray cooling device 10 of the present disclosure, since the flow splitting switch 220 includes a main flow inlet 221 and two flow splitting outlets 222, one end of the main pipeline 210 is communicated with the external water source, the main flow inlet 221 is communicated with the other end of the main pipeline 210, and the two flow splitting outlets 222 are respectively communicated with a flow splitting pipeline 310, which ensures that the flow splitting switch 220 can control different flow directions of the external water source through the switches of their respective pipelines, and the flow splitting pipeline 310 flows the external water source through the cooling channel 331 of the rotating shaft 330 to the cutting blade 20 to achieve the cooling effect of the cutting blades 20 at different installation positions. The present disclosure adopts the opening and closing of the flow splitting switch 220 and does not need to adjust the positions of the main pipeline 210 and the flow splitting pipeline 310 to spray the cutting blade 20, realizing the convenience of the operation of cooling the cutting blade 20.

[0047] 2) In the spray cooling device 10 of the present disclosure, since the interior of the rotating shaft 330 has a cooling channel 331, and the cooling channel 331 is distributed along the direction from the bearing seat 320 to the cutting blade 20. The rotating shaft 330 is provided with a water injection port 330a communicating with the cooling channel 331, and the bearing seat 320 is provided with a connection port 321 communicating with the water injection port 330a, and the connection port 321 is communicated with the shunt pipe 310. When external water source flows in, it passes through the main pipe 210, the shunt pipe 310, the bearing seat 320 and the cooling channel 331 in sequence, and finally reaches the cutting blade 20, achieving the cooling effect when the cutting blade 20 works. Also, since a pressurizing impeller structure is formed in the cooling channel 331, when the rotating shaft 330 rotates, the external water source passing through the cooling channel 331 makes the pressurizing impeller structure increase the water supply pressure of the external water source passing through the cooling channel 331 under the action of the rotational force, improving the water supply effect to the cutting blade 20, thereby ensuring a better cooling effect. And a plurality of groove-shaped holes 332 are formed on the surface of the rotating shaft 330 close to the cutting blade 20, ensuring that the external water source flows into the end face of the cutting blade 20 through the groove-shaped holes 332 and is sprayed onto the entire cutting blade 20 under the action of centrifugal force, thus achieving the cooling effect of the cutting blade 20.

[0048] The above embodiments merely represent several implementation manners of the present disclosure, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
