Description

Technical Field

[0002] The main function of cutting fluid in mechanical processing is to cool and lubricate the tool and workpiece, thereby effectively reducing the heat generated by friction during the cutting process. Computer numerical control machines (CNC machines) also need cutting fluid to flow out of the pipeline to the designated position for auxiliary processing when in use. However, after the processing is completed, the cutting fluid will remain at the interface between the pipeline and the cutting fluid sprayer. Since there is no effective device to prevent the liquid from flowing out, the residual cutting fluid will continue to drip into the working area. During the dripping process, the working area becomes wet, affecting the efficiency of the next clamping of the material. Therefore, a leak-proof cutting fluid spraying stop valve is proposed.

[0007] As a further improvement of the technical solution, a sealing member is fixedly connected to the top of the inner cavity of the liquid stop valve body, and the bottom of the sealing member is in contact with the top of the valve cover.

[0008] As a further improvement of the technical solution, a limiting groove is provided on the top of the valve seat, and a valve cover is slidably connected to the inner wall of the limiting groove.

[0009] As a further improvement of the technical solution, the blocking assembly includes a rotating plate hinged at the bottom of the valve seat, and the inner cavity of the liquid stop valve body is fixedly connected with a tilting frame; The bottom of the tilting frame is an inclined surface, and the bottom of the tilting frame is in contact with the surface of the rotating plate; A baffle is fixedly connected to the bottom of the tilting frame, one end of the baffle away from the tilting frame is fixedly connected to the bottom of the valve seat, and both ends of the rotating plate are in contact with the tilting frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In the leak-proof cutting fluid spray stop valve, by arranging an umbrella-shaped energy dissipation frame and a drainage frame, the cutting fluid entering the water inlet can first contact the umbrella-shaped energy dissipation frame, and the umbrella-shaped energy dissipation frame changes the flow direction of the cutting fluid, disperses the impact force of the cutting fluid, and makes the cutting fluid subsequently flow smoothly along the curvature of the drainage frame surface to the valve cover surface, thereby preventing the cutting fluid from directly falling on the valve cover surface and causing damage to the valve cover, and preventing the impact force generated by the residual cutting fluid directly falling when the cutting fluid device stops working from causing the spring to contract, thereby failing to block the residual cutting fluid.

[0013] 2. In the leak-proof cutting fluid stop valve, the diversion of the drainage frame and the umbrella-shaped energy dissipation frame, and the close fit of the valve cover and the seal due to the operation of the spring, can keep the residual cutting fluid in a1, thereby preventing the residual cutting fluid from flowing out, thereby avoiding contamination of the working area and interference with material replacement.

[0014] 3. In the leak-proof cutting fluid stop valve, if the residual cutting fluid is too much and exceeds the weight borne by the spring, the rotating plate will be in contact with the inclined surface of the tilting frame through the elastic part, thereby blocking the cutting fluid flowing out of the valve cover. At this time, the cutting fluid flowing out will stay in a2 and be blocked by the rotating plate. As the amount of cutting fluid entering cavity a2 increases, the weight of the cutting fluid borne by the spring gradually decreases. At this time, the spring will drive the valve cover to move upward and fit the seal to restore the blocking of the residual cutting fluid in a1. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] When the cutting fluid device stops working, a certain amount of residual cutting fluid will remain in the pipeline between the cutting fluid device interface and the liquid stop valve. Although the liquid stop valve is in a closed state, due to the residual pressure in the pipeline and possible pressure fluctuations, it is difficult for the liquid stop valve to completely prevent the leakage of the cutting fluid. To this end, the present invention provides a leak-proof cutting fluid spraying liquid stop valve, which includes a liquid stop valve body 100, a water inlet 110 is fixedly connected to the top of the liquid stop valve body 100, a threaded connection port 102 is fixedly connected to the bottom of the inner cavity of the liquid stop valve body 100, a water outlet interface 120 is threadedly connected to the surface of the threaded connection port 102, a buffer component 200 is provided in the inner cavity of the water inlet 110, and a control component 300 is provided in the inner cavity of the liquid stop valve body 100 for blocking the residual cutting fluid. The buffer component 200 is used to buffer the direct impact of the cutting fluid on the control component 300, and a cavity for carrying the cutting fluid is formed between the buffer component 200 and the control component 300. The inner cavity of the liquid stop valve body 100 is provided with a blocking component 400, and the blocking component 400 is located at the bottom of the control component 300. A cavity for carrying the cutting fluid flowing out of the control component 300 is formed between the blocking component 400 and the control component 300.

[0019] The water inlet 110 is connected to the water outlet position of the cutting fluid device by manually rotating the stop valve body 100. Then, when the cutting fluid device is working, the cutting fluid can reach the buffer component 200 from the water inlet 110. The buffer component 200 buffers the directly falling cutting fluid. At this time, the directly falling cutting fluid can be prevented from damaging the control component 300. The continuous inflow of cutting fluid will cause the control component 300 to move downward, and the cutting fluid will be transferred to the blocking component 400. The blocking component 400 will transfer the cutting fluid to the inner cavity of the water outlet interface 120 and flow out from the water outlet.

[0020] like Figure 1-10As shown, the present invention takes into account that in actual use, after the cutting fluid sprayed by the cutting fluid device cools the tool, the cutting fluid device needs to be closed. At this time, part of the cutting fluid will remain at the interface between the pipeline and the cutting fluid sprayer. At this time, the remaining cutting fluid will gradually drip onto the workbench surface, causing the working area to be wet and affecting the next clamping of the material. Therefore, it is necessary to set a stop valve to block the cutting fluid remaining at the interface between the pipeline and the cutting fluid after the cutting fluid device stops transmitting the cutting fluid. The cutting fluid device stops transmitting the cutting fluid. At this time, the remaining cutting fluid will stay at the interface of the cutting fluid. Then, the remaining pressure inside the cutting fluid device will cause the cutting fluid to continue to move downward to the inner cavity of the water inlet 110, contacting the surface of the buffer component 200, reducing the impact force of the cutting fluid falling directly, and then, the cutting fluid will fall into the cavity a1 between the control component 300 and the buffer component 200 as shown. Figure 4 Because the cutting fluid device has stopped working, there will be no continuous outflow of cutting fluid. Therefore, the control component 300 can block the residual cutting fluid to prevent the cutting fluid from continuously falling on the work surface and affecting the clamping of materials.

[0021] Considering that if the remaining cutting fluid is more than the weight of the control component 300, the control component 300 will move downward under the action of gravity, causing the cutting fluid to flow out, therefore, by setting a blocking component 400 at the bottom of the control component 300, when the control component 300 moves downward due to the excessive weight of the cutting fluid, the cutting fluid flowing out of it will enter the cavity a2 between the blocking component 400 and the control component 300. Figure 4 As the amount of cutting fluid entering cavity a2 increases, the weight of the cutting fluid borne by the control component 300 gradually decreases. When it drops to a tolerable range, the control component 300 will move upward to resume blocking the residual cutting fluid, while the cutting fluid entering cavity a2 will be further blocked by the blocking component 400, effectively preventing the situation where the control component 300 cannot effectively block the outflow of the cutting fluid due to excessive residual cutting fluid.

[0022] On the basis of the above, the specific structure is disclosed in detail: like Figure 2 As shown, in order to enable the buffer component 200 to buffer the directly falling cutting fluid, thereby protecting the parts of the control component 300, the buffer component 200 includes a drainage rack 210 fixedly connected to the inner wall of the water inlet 110, and four connecting rods 211 are fixedly connected to the inner wall of the drainage rack 210. The end of the connecting rod 211 away from the drainage rack 210 is fixedly connected to a support seat 212, and the top of the support seat 212 is fixedly connected to an umbrella-shaped energy dissipation frame 213 in the shape of an umbrella.

[0023] The drain rack 210 is in the shape of a funnel with a relatively large opening. The cutting fluid entering through the water inlet 110 will first contact the umbrella-shaped energy dissipation rack 213, which will change the flow direction of the cutting fluid and disperse the impact force of the cutting fluid. At this time, the cutting fluid will move from the surface of the umbrella-shaped energy dissipation rack 213 to the surface of the drain rack 210. Since the drain rack 210 is in the shape of a funnel, the cutting fluid reaching the surface of the drain rack 210 will follow its curvature to the top of the control component 300. At this time, the cutting fluid can be prevented from directly contacting the control component 300. The impact force generated causes the control component 300 to move downward, causing the residual cutting fluid to flow out of the inner cavity of the stop valve body 100, and can also protect the control component 300 to prevent damage caused by the impact on the control component 300.

[0024] In order to enable the control component 300 to block the residual cutting fluid, the inner cavity of the stop valve body 100 is fixedly connected to a valve seat 310, the top of the valve seat 310 is fixedly connected to a protrusion 312, the top of the valve seat 310 is fixedly connected to a spring 321, the end of the spring 321 away from the valve seat 310 is fixedly connected to the valve cover 320, and the protrusion 312 is located inside the spring 321.

[0025] The top of the valve cover 320 fits tightly with the top of the inner cavity of the stop valve body 100. After the cutting fluid device stops delivering the cutting fluid, the residual cutting fluid will continue to move downward under the action of its own gravity and the residual pressure in the pipeline, and contact the surface of the umbrella-shaped energy dissipation frame 213. At this time, the umbrella-shaped energy dissipation frame 213 will buffer the cutting fluid. The cutting fluid buffered by the umbrella-shaped energy dissipation frame 213 will reach the top of the valve cover 320. Due to the fit between the top of the valve cover 320 and the top of the inner cavity of the stop valve body 100, the cutting fluid can stay in a1, blocking the cutting fluid and preventing the control component 300 from flowing out the residual cutting fluid, thereby avoiding contamination of the working area and interference with subsequent operations such as clamping materials.

[0026] Considering that the fitting of the valve cover 320 and the top of the inner cavity of the stop valve body 100 blocks the cutting fluid, the spring 321 may shrink to a certain extent due to the falling of the cutting fluid. Therefore, the sealing member 101 is fixedly connected to the top of the inner cavity of the stop valve body 100, and the bottom of the sealing member 101 contacts the top of the valve cover 320. By arranging the sealing member 101 at the top of the inner cavity of the stop valve body 100, the valve cover 320 and the sealing member 101 fit together. At this time, the spring 321 at the bottom of the valve cover 320 will squeeze the sealing member 101. When the cutting fluid falls, the spring 321 Slightly shrinks. Due to the shrinkage of the spring 321, the squeezing effect of the valve cover 320 on the seal 101 is correspondingly weakened. However, relying on the elasticity of the seal 101 itself and its close fit with the valve cover 320, the seal 101 can automatically adjust its shape and fit tightly to the valve cover 320, thereby effectively filling the gap caused by the shrinkage of the spring 321, ensuring that the liquid stop valve can still maintain good sealing performance when the spring 321 is deformed due to the impact of the falling cutting fluid, thereby preventing the cutting fluid from leaking from the gap between the valve cover 320 and the top of the inner cavity of the liquid stop valve body 100.

[0027] Taking into account the characteristics of the spring 321, after the cutting fluid drives the valve cover 320 to move downward, as the force of the cutting fluid weakens or disappears, the spring 321 will cause the valve cover 320 to rebound upward, and it is difficult for the valve cover 320 to move accurately along a vertical upward trajectory. Therefore, a limiting groove 311 is opened on the top of the valve seat 310, and the valve cover 320 is slidably connected to the inner wall of the limiting groove 311. Since the valve cover 320 slides on the inner wall of the limiting groove 311, the movement trajectory of the valve cover 320 driven by the spring 321 during the expansion and contraction process will also follow the shape and direction of the limiting groove 311, so that after the cutting fluid device stops working, the valve cover 320 can move vertically upward so that it can fit stably and accurately with the seal 101.

[0028] In order to enable the blocking component 400 to further block the cutting fluid flowing out of the control component 300, the parts of the blocking component 400 need to be disclosed. Therefore, the blocking component 400 includes a rotating plate 410 hinged at the bottom of the valve seat 310, and the inner cavity of the stop valve body 100 is fixedly connected with a tilting frame 420.

[0029] The bottom of the tilting frame 420 is an inclined surface, and the bottom of the tilting frame 420 is in contact with the surface of the rotating plate 410. The bottom of the tilting frame 420 is fixedly connected with a baffle 430. The end of the baffle 430 away from the tilting frame 420 is fixedly connected to the bottom of the valve seat 310. The two ends of the rotating plate 410 are in contact with the tilting frame 420 and move downward through the valve cover 320. At this time, the cutting fluid will enter the surface a2 of the rotating plate 410 along the valve cover 320. Figure 4 At this time, the fit between the rotating plate 410 and the tilting frame 420 can block the cutting fluid reaching the surface of the rotating plate 410 and prevent the cutting fluid from flowing out.

[0030] In order to make the rotating plate 410 and the tilting frame 420 fit together, thereby blocking the cutting fluid, a groove is opened at the bottom of the tilting frame 420, and an elastic member 411 is fixedly connected to the inner wall of the groove. The end of the elastic member 411 away from the groove is fixedly connected to the surface of the rotating plate 410. By setting the elastic member 411 on the inner wall of the groove opened by the tilting frame 420, the elastic member 411 can pull the rotating plate 410 to contact and fit with the inclined surface of the tilting frame 420, thereby blocking the cutting fluid on the surface of the rotating plate 410.

[0031] Taking into account that the cutting fluid flowing out of the rotating plate 410 is not evenly distributed when the cutting fluid device is working, a diverter assembly 500 is provided at the center position of the inner cavity of the water outlet interface 120. The diverter assembly 500 includes a diverter ring 510 fixedly connected to the center position of the inner cavity of the water outlet interface 120, and a connecting column 520 is fixedly connected to the inner wall of the diverter ring 510. By providing the diverter ring 510, the cutting fluid flowing out of the rotating plate 410 can be dispersed by the diverter ring 510, so as to flow out from the water outlet interface 120 evenly.

[0032] Working principle: like Fig. 9 When the cutting fluid device is working, the working principle of the leak-proof cutting fluid stop valve is as follows: the stop valve body 100 is moved to connect the water inlet 110 with the water outlet of the cutting fluid device. The operation of the cutting fluid device can allow the cutting fluid to enter from the water inlet 110 and contact the umbrella-shaped energy dissipation frame 213. At this time, the umbrella-shaped energy dissipation frame 213 will change the flow direction of the cutting fluid and disperse the impact force of the cutting fluid, so that the cutting fluid will not directly fall onto the surface of the valve cover 320 and cause damage to the surface of the valve cover 320. At this time, the weight of the continuously falling cutting fluid will When the pressure is greater than the limit that the spring 321 can withstand, the spring 321 will shrink, and the valve cover 320 will move to the inner wall of the limit groove 311. Then, the cutting fluid on the surface of the valve cover 320 will reach the surface of the rotating plate 410. Since the weight of the continuously falling cutting fluid is heavy enough, the elastic member 411 will be stretched, and the surface of the rotating plate 410 will be separated from the inclined surface of the tilting frame 420. At this time, the cutting fluid will fall into the inner cavity of the water outlet interface 120, and will be dispersed by the diverter ring 510 in the inner cavity of the water outlet interface 120, and will flow out of the water outlet interface 120.

[0033] like Figure 4When the cutting fluid device stops working, the leak-proof cutting fluid stop valve works as follows: Since the cutting fluid device stops working, there will be no continuous cutting fluid outflow at this time, but the cutting fluid remaining at the interface between the pipeline and the cutting fluid will move downward due to the internal residual pressure and the gravity of the cutting fluid itself and contact the surface of the umbrella-shaped energy dissipation frame 213, and the impact force of the cutting fluid on the umbrella-shaped energy dissipation frame 213 will be alleviated, and the cutting fluid will gradually stay on the surface a1 of the valve cover 320, thereby blocking the remaining cutting fluid. When the amount of cutting fluid exceeds the weight that the spring 321 can bear, the spring 321 will contract and the valve cover 320 will slide on the inner wall of the limit groove 311, allowing the cutting fluid to flow into the surface a2 of the rotating plate 410. At this time, as the amount of cutting fluid entering the cavity a2 increases, the weight of the cutting fluid borne by the spring 321 gradually decreases, and the spring 321 will drive the valve cover 320 to move upward and contact with the seal 101, thereby restoring the blocking of the residual cutting fluid. At this time, the residual cutting fluid in a2 will be blocked by the elastic member 411.
