[0003] It can be seen that in the process of machining parts, the existing five-axis CNC machining centers mostly place the pre-machined part blocks on the five-axis chuck and clamp them, then drive the five-axis CNC body to push the clamped part blocks to the cutting edge of the CNC tool, and drive the CNC tool to rotate and cut the part blocks, and at the same time use the cutting fluid to directly spray the CNC tool for synchronous cooling, thereby assisting the CNC tool to complete the cutting and production of parts. However, in the actual five-axis CNC machining center processing parts scene, due to the excessively fast flow rate of the direct-spray cutting fluid, the debris after the CNC tool cuts the parts is splashed everywhere, which not only causes trouble for cleaning the workbench after use, but also too much part debris adheres to the surface of the cut part, resulting in obstruction of the cutting fluid flow, reducing the contact area between the cutting fluid and the tool and parts, reducing the cooling efficiency, causing unnecessary waste of cutting fluid resources, and seriously affecting the normal use of cutting fluid flushing cooling.

[0043] The bottom of the support plate 22 is fixedly connected with a column rod 210 . Two column rods 210 are provided and are symmetrically distributed. The bottoms of the two column rods 210 penetrate and are inserted into the top of the fixing plate 211 .

[0044] The front side of the support plate 22 is sleeved with a swing rod 1 213, the bottom of the swing rod 1 213 is rotatably connected to a swing rod 214, the right end of the swing rod 214 is sleeved with a piston rod 215, the outer surface of the piston rod 215 is penetrated and inserted with an air cylinder 217, the bottom of the piston rod 215 is slidingly and sealingly connected between the inner walls of the air cylinder 217, the top left side of the air cylinder 217 is penetrated and rotatably connected to the bottom of the swing rod 214, a drainage tube 1 218 is penetrated and inserted at the bottom of the right side of the air cylinder 217, the output end of the drainage tube 1 218 is penetrated and inserted with a pressure tank 219, the bottom of the pressure tank 219 is fixedly connected to the top of the fixed plate 211, the top right side of the pressure tank 219 is penetrated and inserted with a drainage tube 220, and the output end of the drainage tube 220 is penetrated and inserted into the outer surface of the liquid outlet pipe 29.

[0045] An elastic inclined plate 216 is inserted through the inner bottom wall of the liquid outlet pipe 29. Two elastic inclined plates 216 are provided. The two elastic inclined plates 216 are symmetrically distributed. An elastic inclined plate 222 is inserted through and elastically connected to the bottom nozzle of the liquid outlet pipe 29. The bottom inclined surface of the elastic inclined plate 216 is slidably connected to the elastic inclined plate 222.

[0046] A cutting fluid box 28 is fixedly connected between the inner walls of the integrated drill box 12, the front end of the cylindrical tube 27 is inserted through the cutting fluid box 28, the input end of the liquid outlet pipe 29 is inserted through the left side of the cutting fluid box 28, and the bottom of the integrated drill box 12 is rotatably connected to the drill bit 13.

[0047] In the prior art, the cutting fluid is cooled by direct spraying to the CNC tool. When in use, the cutting fluid flow rate of the direct spraying is too fast, resulting in the debris after the CNC tool cuts the parts being splashed everywhere, which not only causes trouble in cleaning the workbench after use, but also too much debris adheres to the surface of the part after cutting, resulting in obstruction of the cutting fluid flow, reducing the contact area between the cutting fluid and the tool and the part, reducing the cooling efficiency, and causing unnecessary waste of cutting fluid resources. The present application sets a lifting and spraying speed adjustment component 2. When in use, the output end of the ventilation drive cylinder 21 is extended to the right, driving the fixedly connected slider 25 to move to the right, thereby causing the slider 25 to drive the L-shaped hollow swing plate 26 to move along the L-shaped groove plate 2 3 moves to the right, and at the same time, the slider 25 drives the cylindrical tube 27, the cutting fluid box 28, the liquid outlet pipe 29, the integrated drill box 12 and the drill bit 13 to move to the right. When the rear end of the L-shaped hollow swing plate 26 moves to the right to the rightmost side of the horizontal groove of the L-shaped groove plate 23, the front bottom of the L-shaped hollow swing plate 26 can be rotated around the axis of the slider 25 under the action of the continuous rightward extension force of the output end of the cylinder 21, and the L-shaped hollow swing plate 26 drives the cylindrical tube 27 to rotate, and the cylindrical tube 27 drives the cutting fluid box 28, the liquid outlet pipe 29, the integrated drill box 12 and the drill bit 13 to rotate, so that after the rear end of the L-shaped hollow swing plate 26 rotates to be flush with the top wall of the vertical groove of the L-shaped groove plate 23, the drill bit 13 is indirectly It can be rotated to a vertical state, and the bottom of the drill bit 13 is located directly above the part clamped by the five-axis machine body 11. At this time, the output end of the cylinder 212 can be driven to shrink downward by ventilation, and the fixedly connected support plate 22 can be driven to move downward, so that the support plate 22 drives the cylinder 1 21 and the L-shaped groove plate 23, the slider 25, the L-shaped hollow swing plate 26 and the cylindrical tube 27, the cutting fluid box 28, the liquid outlet pipe 29, the integrated drill box 12, and the drill bit 13 to move downward, and at the same time, the support plate 22 drives the swing rod 1 213 to move downward, and then the bottom of the swing rod 1 213 squeezes the swing rod 214 to move downward, and drives the swing rod 214 to rotate around the left axis of the top of the air cylinder 217. At this time, the right end of the swing rod 214 can pull the piston The rod 215 moves upward along the inside of the air cylinder 217, so that the inner cavity of the air cylinder 217 forms an air suction power state, and then the air cylinder 217 can provide air suction power for the inner cavity of the drainage tube 218, so that the drainage tube 218 can suck the compressed gas in the pressure tank 219 into the air cylinder 217, so that the piston rod 215 can perform a lifting decompression adjustment operation on the compressed gas in the pressure tank 219, and further enable the drainage tube 220 to drain the decompressed gas in the pressure tank 219 into the liquid outlet pipe 29, and finally, after the decompressed gas in the drainage tube 220 contacts the cutting fluid in the liquid outlet pipe 29, the flow rate of part of the cutting fluid will be slowed down, thereby realizing a covering slow-flow spraying operation on the cutting fluid in the liquid outlet pipe 29.Avoid the problem of splashing of parts due to excessively fast cutting fluid spraying speed from the outlet pipe 29 when the drill bit 13 descends to drill and cut parts, reduce the problem of poor cooling effect of cutting fluid and waste of resources, improve the efficiency of cutting fluid cooling the drill bit 13, increase the strength of cutting fluid to clean parts without splashing, and ensure the normal use of cutting fluid cooling process;

[0048] If the support plate 22 is lowered to be flush with the top of the fixed plate 211, the drill bit 13 can complete the first drilling and cutting process of the part. At this time, the output end of the cylinder 212 can be driven to extend upward, driving the support plate 22 to drive the swing rod 1 213 to move upward, and then the bottom of the swing rod 1 213 pulls the swing rod 214 to move upward, and drives the swing rod 214 to rotate around the left axis of the top of the cylinder 217. At this time, the right end of the swing rod 214 can push the piston rod 215 along the cylinder The interior of the cylinder 217 moves downward, so that the inner cavity of the cylinder 217 can form a blowing force, so that the cylinder 217 can provide a blowing force for the inner cavity of the drainage tube 1 218, and then the drainage tube 1 218 can perform a gas-increasing operation on the inner cavity of the pressure tank 219, so that the piston rod 215 can perform a pressurized inflation operation on the compressed gas in the pressure tank 219, and further the drainage tube 220 can drain the pressurized gas in the pressure tank 219 to the liquid outlet pipe 29, and then the drainage tube 220 can be filled with gas. After the high-pressure gas contacts the cutting fluid in the liquid outlet pipe 29, the flow rate of the cutting fluid will become faster. When the high-speed flowing cutting fluid flows to the nozzle position of the liquid outlet pipe 29, the two elastic inclined plates 216 will, under the action of the impact force of the cutting fluid, move the elastic inclined plate 216 on the left inner bottom wall of the liquid outlet pipe 29 downward to squeeze the elastic inclined plate 222 to move to the right, and simultaneously move the elastic inclined plate 216 on the right inner bottom wall of the liquid outlet pipe 29 downward to squeeze the other elastic inclined plate 222 to move to the left, so that the two elastic inclined plates 222 can move together, thereby realizing the point-by-point adjustment of the spray volume at the nozzle end of the liquid outlet pipe 29, avoiding the splashing of parts debris when the cutting fluid with too fast a spray speed flushes and cools the cutting part of the drill bit 13, and the incomplete contact between the cutting surface of the part and the position to be cooled of the drill bit 13, resulting in the problem of poor cooling effect of the cutting fluid, reducing the problem of waste of cutting fluid resources, improving the cooling efficiency of the cutting fluid, increasing the cooling effect of the drill bit 13 without splashing debris, and ensuring the normal progress of the part processing cooling process.

[0049] It should be noted that the adjustment of the cutting fluid spraying speed of the liquid outlet pipe 29 is to indirectly provide pressure relief and pressure boosting power for the pressure tank 219 through the telescopic movement of the piston rod 215. When the pressure tank 219 provides pressure relief power for the drainage pipe 220, the drainage pipe 220 can cover the cutting fluid in the liquid outlet pipe 29 with a slow-flow spraying speed, further reducing the impact force of the cutting fluid spraying into the surface of the drill bit 13, and strengthening the cooling of the cutting friction part of the drill bit 13. When the boost power is provided, the flow rate of the cutting fluid in the liquid outlet pipe 29 can be indirectly accelerated, so that when the cutting fluid flows to the nozzle of the liquid outlet pipe 29, the elastic inclined plate 1 216 can be pressed down by the two elastic inclined plates 1 216 under the impact force of the cutting fluid to adjust the opening size of the two elastic inclined plates 222, thereby completing the point-type spray volume adjustment switching of the liquid outlet pipe 29, further ensuring the high efficiency of cooling the drill bit 13 and the drilling cutting surface of the part, thereby completing the cooling process of the part and the drill bit 13.

[0050] This solution provides a lifting and lowering spray speed adjustment component 2. During the continuous up and down movement of the piston rod 215, the liquid outlet pipe 29 can be indirectly driven to perform a covering slow-flow spray speed operation and a point-type spray volume adjustment operation, thereby avoiding excessive cutting fluid spray speed, which causes splashing when the cutting fluid flushes the cooling drill bit 13 and the debris on the cutting surface of the part, causing difficulties in cleaning after cutting, reducing unnecessary waste of cutting fluid resources, improving the accuracy of cutting fluid cooling the drill bit 13, and increasing the effect of splash-free flushing and cooling of debris after part cutting, thereby ensuring the normal use of the cutting fluid cooling process.

[0051] like Figures 6 to 8 As shown, a cooling and lubricating component 3 is provided inside the lifting and lowering injection speed regulating component 2;

[0052] The cooling and lubrication assembly 3 includes a sodium oleate soap box 31, which is fixedly connected to the top of the support plate 22. The inner bottom wall of the sodium oleate soap box 31 is fixedly connected to a water pump 32. The output end of the water pump 32 is penetrated and plugged with an infusion tube 33, and the output end of the infusion tube 33 is penetrated and plugged into the rear end of the L-shaped hollow swing plate 26.

[0053] By setting up the cooling and lubricating component 3, when in use, the L-shaped hollow swing plate 26 can be moved to the right, and the water pump 32 can be powered on to transport the sodium oleate soap liquid in the sodium oleate soap box 31 to the infusion pipe 33, and then the infusion pipe 33 will transport the transported sodium oleate soap flow to the L-shaped hollow swing plate 26, and then the L-shaped hollow swing plate 26 will introduce the sodium oleate soap into the cutting fluid box 28, so that the sodium oleate soap can cool the cutting fluid, and avoid the cutting fluid being unable to penetrate into the cutting gap between the drill bit 13 and the part when cooling the drill bit 13 and the cutting surface of the part, resulting in the drill bit 13 being cut for a long time due to excessive friction temperature, resulting in the drill bit 13 becoming blunt, the part drilling and cutting deformation and blackening, reducing the phenomenon of the drill bit 13 cutting parts at high temperature, improving the flexibility of the cutting fluid to soak and cool the drill bit 13, and strengthening the strength of the cutting fluid to penetrate and cool the gap of the part, to ensure the normal use of the part processing cooling.

[0054] It should be noted that the sodium oleate soap agent strengthens the cooling process of the cutting fluid. When the L-shaped hollow swing plate 26 moves to the right, the sodium oleate soap agent in the sodium oleate soap agent box 31 is indirectly transferred to the cutting fluid box 28 and merged with the cutting fluid in the cutting fluid box 28, thereby increasing the cooling effect and lubrication and wetting effect of the cutting fluid. This ensures that when the liquid outlet pipe 29 performs point-type spray cooling on the cutting surface of the part, the cutting fluid can penetrate into the gap of the part drilling and cutting, thereby ensuring that the drill bit 13 can cool the drilling and cutting parts normally for a long time.

[0055] By setting a cooling and lubricating component 3, the present solution can indirectly transfer the sodium oleate soap in the sodium oleate soap box 31 to the cutting fluid box 28 under the action of the suction power of the water pump 32, so that the sodium oleate soap can cool the cutting fluid in the cutting fluid box 28, thereby avoiding the cutting fluid from failing to cool the cutting gap between the drill bit 13 and the parts, resulting in a decrease in the accuracy of the drill bit 13 and severe wear of the parts due to excessive friction heat between the drill bit 13 and the cutting contact surface, reducing the possibility of the cutting fluid failing to penetrate the cutting gap, improving the wettability of the cutting fluid in cooling the drill bit 13, strengthening the cooling effect of the cutting fluid, increasing the range of the cutting fluid lubricating and cooling parts, and ensuring the normal CNC machining of the parts.

[0056] like Fig. 9 and Fig.10 As shown, the interior of the lifting and lowering spray speed regulating component 2 is provided with a quantity regulating component 4;

[0057] The amount adjustment component 4 includes an annular plate 41, which is fixedly connected to the front side of the slider 25. The front circular surface of the annular plate 41 is provided with slide grooves 42 in sequence. There are four slide grooves 42, and the four slide grooves 42 are vertically distributed in pairs. The interiors of the four slide grooves 42 are penetrated and slidably connected with column blocks 45. The front ends of the four column blocks 45 are rotatably connected with fan-shaped liquid partition plates 44. The rear end outer wall of the cylindrical tube 27 is provided with an arc groove 43. There are four arc grooves 43, and the four arc grooves 43 are distributed in a ring shape.

[0058] The outer surface of the fan-shaped liquid isolation plate 44 penetrates and is rotatably connected to the arc-shaped groove 43 , and the bottom end of the fan-shaped liquid isolation plate 44 is sleeved between the inner walls of the arc-shaped groove 43 .

[0059] By setting the adjustment component 4, when working, the four fan-shaped liquid partition plates 44 can be indirectly driven to rotate around the axis of the rear side wall of the arc groove 43 while the L-shaped hollow swing plate 26 and the cylindrical tube 27 rotate, so that the sliding end of the fan-shaped liquid partition plate 44 inserted into the outer side of the arc groove 43 can pull the column block 45 to slide to the right along the inside of the slide groove 42, and then when the column block 45 moves to the right to be flush with the rightmost end of the slide groove 42, the four fan-shaped liquid partition plates 44 can be coupled to each other, forming a into a closed state, thereby realizing that the four fan-shaped partition plates 44 can perform a rotational flow adjustment operation on the inner cavity of the cylindrical tube 27, thereby preventing excessive sodium oleate soap from flowing into the cutting fluid box 28, causing an imbalance in the ratio of cutting fluid and sodium oleate soap, leading to the problem of failure of cutting fluid cooling, reducing the occurrence of poor effects of cutting fluid cooling the drill bit 13 and parts, improving the efficiency of cooling by the cutting fluid fusion sodium oleate soap, enhancing the cooling and lubrication effect of the sodium oleate soap, and ensuring the normal use of cutting fluid penetration cooling.

[0060] It should be noted that the process of controlling the intake of sodium oleate soap is to maintain a high effect of the cutting fluid in cooling the drill bit 13 and parts, and the four fan-shaped partition plates 44 only start to close the inner cavity of the cylindrical tube 27 after a certain amount of sodium oleate soap is taken into the cutting fluid while the L-shaped hollow swing plate 26 rotates, and after the four fan-shaped partition plates 44 are completely coupled and closed, the power supply of the water pump 32 can be disconnected and the suction output can be stopped, thereby completing the enhancement of the cutting fluid effect and controlling the output of the sodium oleate soap.

[0061] By setting up the volume adjustment component 4, the present scheme can indirectly drive the four fan-shaped liquid partition plates 44 to perform a rotational flow adjustment operation under the action of the rotational movement of the cylindrical tube 27, so as to avoid the problem of uneven intake of the sodium oleate soap activator in the cutting fluid, which causes a decrease in the cooling effect of the cutting fluid, reduces the cooling failure problem of the drill bit 13 and parts, improves the flexibility of the sodium oleate soap activator to enhance cooling, strengthens the strength of the cutting fluid to cool the drill bit 13 and parts, and ensures the normal cooling effect of the cutting fluid.

[0062] like Fig.11 and Fig.12 As shown, a corner assembly 5 is provided inside the CNC machine room 1;

[0063] The corner assembly 5 includes a drive motor 51, which is fixedly connected to the inner bottom wall of the CNC machine room 1. The output end of the drive motor 51 is fixedly connected to a spur gear 52. The top of the spur gear 52 is meshed with a semi-annular rack 53. The inner ring surface of the semi-annular rack 53 is fixedly connected to the outer wall of the hollow semi-cylindrical box 223.

[0064] By setting the corner assembly 5, when working, after the drill bit 13 completes the drilling and cutting of the part clamped by the five-axis machine body 11, the output end of the second cylinder 212 can be ventilated and started to extend upward, and the drill bit 13 can be indirectly driven to move upward until it is separated from the top surface of the part cutting, and the extension of the output end of the second cylinder 212 can be stopped. At this time, the output shaft of the driving motor 51 can be driven to rotate, and the fixedly connected spur gear 52 can be driven to rotate, so that the spur gear 52 drives the semi-annular rack 53 meshing at the top to rotate, and then the semi-annular rack 53 pulls the hollow semi-cylindrical box 223 to rotate, further making the hollow semi-cylindrical box 223 rotate. The core semi-cylindrical box 223 drives the lifting and lowering spray speed adjustment component 2, the cooling and lubrication component 3 and the amount adjustment component 4 as well as the drill bit 13 and the integrated drill box 12 to rotate, so that the liquid outlet pipe 29 can perform an angle spray cooling operation on the five-axis body 11 used for clamping parts, thereby avoiding the problem of residual part debris adhering to the heat dissipation surface of the five-axis body 11 after part cutting, causing the heat dissipation blockage of the five-axis body 11, reducing the possibility of residual debris corroding the five-axis body 11, improving the cooling effect of the five-axis body 11, increasing the cooling service life of the five-axis body 11, and ensuring the normal progress of the five-axis CNC machining process.

[0065] It should be noted that the cooling process of the five-axis machine body 11 is that after the drill bit 13 completes the drilling and cutting of the parts, the hollow semi-cylindrical box 223 starts to drive the liquid outlet pipe 29 to rotate, so that the liquid outlet pipe 29 rotates a certain angle to flush and cool the machine body and debris in different directions of the five-axis machine body 11, ensuring the cleanliness of the five-axis machine body 11 for secondary use and improving the efficiency of five-axis CNC machining parts.

[0066] Method of use: When the present invention is used, first install the CNC machine room 1 on the designated processing position, then inject cutting fluid and sodium oleate soap activator into the cutting fluid box 28 and the sodium oleate soap agent box 31 respectively, then manually open the front door of the CNC machine room 1, place the pre-cut parts block on the clamping plate of the five-axis machine body 11 and clamp it, close the front door of the CNC machine room 1, then the output end of the cylinder 1 21 in the lifting and spray speed adjustment component 2 can be ventilated to extend to the left, and the output end of the ventilation drive cylinder 2 212 can be retracted downward, so that the liquid outlet pipe 29 can perform covering slow flow spray speed operation and point-type spray volume adjustment operation, then the lifting and spray speed adjustment component 2 drives the cooling and lubrication component 3 to spray the cutting fluid in the cutting fluid box 28 with the sodium oleate soap activator for cooling operation, and further the lifting and spray speed adjustment component 2 drives The regulating component 4 performs a rotational flow adjustment operation, and then makes the output shaft of the driving motor 51 in the corner component 5 rotate, which can indirectly drive the liquid outlet pipe 29 to perform a corner liquid spray cooling operation on the surface of the five-axis body 11. After the chip cooling of the five-axis body 11 is completed, the output shaft of the driving motor 51 can be driven to rotate again, so that the drill bit 13 can be rotated to the top of the five-axis body 11 again. Then, when the output end of the ventilation start cylinder 2 212 extends upward to be flush with the lateral end of the L-shaped groove 1 221, the operation of cylinder 2 212 is stopped, and the output end of cylinder 1 21 is started again to retract to the right. When the rear side of the L-shaped hollow swing plate 26 moves to the right to be flush with the leftmost end of the L-shaped groove plate 23, the operation of cylinder 1 21 is stopped, and then the front door of the CNC machine room 1 is opened, the cut parts are taken out, and the device stops running.
