Description

Technical Field

[0001] The present invention relates to the technical field of titanium alloy rod processing, and more specifically, to a device and method for preparing high-quality TC4 titanium alloy large-size rods. Background Art

[0002] High-quality TC4 titanium alloy large-size rod is a metal material with high precision, high hardness, high wear resistance and high fatigue strength. It is widely used in machinery manufacturing, automobile manufacturing, aerospace and medical equipment. When processing TC4 titanium alloy large-size rods, in order to remove excess material on the surface of the rod and obtain the required shape and size accuracy, a milling device is required.

[0003] Existing milling devices are mostly composed of a driving module, a distance adjustment module, a milling cutter, a cooling pipe, a clamping module and an electric module, and their working principle is as follows: the clamping module clamps and fixes both ends of the titanium alloy rod, and the distance adjustment module is connected to the milling cutter, and the distance adjustment module controls the milling cutter to be close to the titanium alloy rod. At this time, the electric module drives the clamping module to rotate, and the rotation of the clamping module will drive the titanium alloy rod to rotate. The rotation of the titanium alloy rod generates friction with the milling cutter, and the milling cutter mills the outside of the titanium alloy rod, and the cooling pipe sprays coolant on the contact point between the milling cutter and the titanium alloy rod to reduce the temperature generated by the contact between the milling cutter and the titanium alloy rod. The driving module can drive the distance adjustment module to move horizontally, and drive the milling cutter to move through the distance adjustment module to evenly mill different positions of the titanium alloy rod. Finally, the processed titanium alloy rod can be removed.

[0036] 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.

[0037] See also Figure 1 - Figure 6 As shown, a high-quality TC4 titanium alloy large-size bar preparation device includes a processing table 1 and a pair of clamping modules 2, a titanium alloy bar is installed between the pair of clamping modules 2, the clamping module 2 is away from the titanium alloy bar and an electric module is installed, the electric module is used to drive the clamping module 2 to rotate, a driving module 3 is installed at the top of the processing table 1, a distance adjustment module 4 is installed on the outside of the driving module 3, a milling cutter 5 is installed at the top of the distance adjustment module 4, and the milling cutter 5 is fitted with the titanium alloy bar, and also includes:

[0038] Sponge 6, sponge 6 is arranged on the outside of the titanium alloy rod, a lifting rod 7 is glued inside the sponge 6, the outside of the lifting rod 7 is slidably connected to a limiting square tube 8, a connecting frame 9 is fixedly connected to the outside of the limiting square tube 8, the connecting frame 9 is fixedly connected to the top of the distance adjustment module 4, a cooling pipe is installed inside the connecting frame 9, the cooling pipe is used to spray coolant, a transmission mechanism is arranged on the periphery of the limiting square tube 8, and the transmission mechanism is used to move the lifting rod 7;

[0039] The coil spring 10 is arranged on the outside of the lifting rod 7 , and a retention mechanism cooperating with the lifting rod 7 is arranged on the outside of the coil spring 10 .

[0040] When the cooling tube sprays coolant on the titanium alloy rod, the chemical components in the coolant adhere to the surface of the titanium alloy rod for a long time, and may react with the surface of the titanium alloy rod, resulting in spots, corrosion or discoloration on the surface, which not only affects the appearance quality of the titanium alloy, but also may reduce its corrosion resistance and mechanical properties. When the embodiment of the present invention is in use, the clamping module 2 clamps and fixes the two ends of the titanium alloy rod, and the distance adjustment module 4 is connected to the milling cutter, and the distance adjustment module 4 controls the milling cutter to approach the titanium alloy rod. At this time, the power module drives the clamping module 2 to rotate, and the rotation of the clamping module 2 will drive the titanium alloy rod to rotate. The rotation of the titanium alloy rod generates friction with the milling cutter, so that the milling cutter moves the outer side of the titanium alloy rod. Milling is performed, and the cooling pipe sprays coolant on the contact point between the milling cutter and the titanium alloy rod to reduce the temperature generated by the contact between the milling cutter and the titanium alloy rod. The driving module 3 can drive the distance adjustment module 4 to move horizontally, and the distance adjustment module 4 drives the milling cutter to move, so as to evenly mill different positions of the titanium alloy rod. When the milling cutter 5 contacts the titanium alloy rod, the transmission mechanism drives the lifting rod 7 to move downward along the inside of the limiting square tube 8. The downward movement of the lifting rod 7 will drive the sponge 6 to move downward and contact the titanium alloy rod. Then, under the action of the coil spring 10, the coil spring 10 releases elastic potential energy after deformation, drives the retention mechanism to operate, and forces the sponge 6 to remain stationary. As the titanium alloy rod rotates, the sponge 6 will move along the titanium alloy. The position of the milling cutter on the rod is used for adsorption of impurities and waste liquid, thereby preventing the chemical components in the coolant from adhering to the surface of the titanium alloy rod for a long time. It should be noted that the sponge 6 is a fire-retardant sponge with fire-proof and water-absorbing functions. When the sponge 6 is stationary for a period of time, although there is the blessing of the coolant, the surface of the titanium alloy rod will still have a certain temperature. At this time, the transmission mechanism will push the retention mechanism, and the retention mechanism will drive the coil spring 10 to deform again under the force, and end the restriction on the lifting rod 7. The transmission mechanism will drive the sponge 6 to rise and reset through the lifting rod 7, thereby avoiding the sponge 6 from being attached to the titanium alloy rod for a long time, causing the surface temperature to be too high and damage to occur. It should be noted that, although the sponge 6 intermittently reciprocates up and down under the action of the transmission mechanism and the retention mechanism, there is a certain period of contact gap between the sponge 6 and the titanium alloy rod, but the area of ​​the sponge 6 is larger than the area of ​​the milling cutter, and the speed at which the driving module 3 drives the distance adjustment module 4 to move horizontally is slow. When the sponge 6 contacts the titanium alloy rod next time, the contact area can make up for the gap period when it is separated. As the driving module 3 drives the milling cutter to move and the sponge 6 to move reciprocally up and down through the distance adjustment module 4, the milling cutter evenly mills the outside of the titanium alloy rod, and the sponge 6 evenly cleans the coolant attached to the outside of the titanium alloy rod. Finally, the processed titanium alloy rod can be removed;

[0041] The clamping module 2, the driving module 3, the distance adjustment module 4 and the power module are all existing technologies in milling, and the technology is mature. The functions are briefly introduced in the article without elaborating too much.

[0042] like Figure 3 - Figure 6 As shown, the transmission mechanism includes a power assembly and a reset assembly, and the power assembly includes a support rod 11, a motor 12, a turntable 13, a protrusion 14, a fixed rod 15 and a roller 16. The support rod 11 is fixedly connected to the outer side of the limiting square tube 8, and the motor 12 is installed on the side of the support rod 11 away from the limiting square tube 8. The turntable 13 is arranged on the side of the support rod 11 away from the motor 12, and the turntable 13 is transmission-connected to the output end of the motor 12, the protrusion 14 is fixedly connected to the outer side of the turntable 13, the fixed rod 15 is fixedly connected to the outer side of the lifting rod 7, and the roller 16 is rotatably connected to the outer side of the fixed rod 15. The reset assembly includes a first fixed plate 17, a second fixed plate 18 and a first spring 19, and the first fixed plate 17 and the second fixed plate 18 are respectively fixedly connected to the outer sides of the lifting rod 7 and the limiting square tube 8, and the first spring 19 is fixedly connected between the first fixed plate 17 and the second fixed plate 18.

[0043] When the motor 12 is running, it drives the turntable 13 to rotate. The rotation of the turntable 13 drives the protrusion 14 to rotate synchronously. As the turntable 13 rotates, the protrusion 14 reaches the position of the roller 16, and the inclined surface of the protrusion 14 squeezes the roller 16, so that the roller 16 is subjected to force, driving the fixed rod 15 to move downward, and the downward movement of the fixed rod 15 drives the sponge 6 to move downward through the lifting rod 7. During the downward movement of the lifting rod 7, the first fixed plate 17 is driven to squeeze the first spring 19, so that the first spring 19 is deformed and generates elastic potential energy, and the sponge 6 When it moves downward, it will fit with the surface of the titanium alloy rod. As the titanium alloy rod rotates, the sponge 6 will clean the surface of the titanium alloy rod. When the protrusion 14 passes over the roller 16, the squeezing of the roller 16 by the protrusion 14 ends. It should be noted that when the turntable 13 drives the protrusion 14 to rotate, the protrusion 14 will not hit the first fixed plate 17. The first spring 19 is no longer stressed at this time, and the elastic potential energy is released instantly, driving the lifting rod 7 to reset through the first fixed plate 17. The reset of the lifting rod 7 will drive the sponge 6 to reset and break away from the fit with the titanium alloy rod.

[0044] like Figure 4 and Figure 5 As shown, the retention mechanism includes a rotating plate 20, an inclined block 21, a guide rod 22, a block 23 and a push rod 24. The rotating plate 20 is rotatably connected to the outer side of the fixed rod 15. The rotating plate 20 is designed in an "L" shape. The inclined block 21 is fixed to the end of the rotating plate 20 away from the fixed rod 15. The inclined block 21 is designed in a "right triangle". The guide rod 22 is fixed to the outer side of the rotating plate 20, the block 23 is fixed to the outer side of the limiting square tube 8, and the push rod 24 is fixed to the inside of the turntable 13.

[0045] As the fixed rod 15 moves downward, the fixed rod 15 will synchronously drive the rotating plate 20 to move downward. As the rotating plate 20 moves downward, the rotating plate 20 drives the inclined surface of the inclined block 21 to contact the inclined surface of the clamping block 23. Since the position of the clamping block 23 is fixed, the inclined block 21 drives the rotating plate 20 to make a circular motion with the fixed rod 15 as the center. The movement of the rotating plate 20 will stretch the coil spring 10, causing the coil spring 10 to deform and generate elastic potential energy. When the inclined block 21 reaches the half position of the clamping block 23, the clamping block 23 ends its squeezing of the inclined block 21, and the coil spring 10 is stretched. When the spring 10 is no longer stressed, the elastic potential energy is released instantly, driving the rotating plate 20 to reverse and reset. The reverse reset of the rotating plate 20 will drive the inclined block 21 to reverse and reset. After the inclined block 21 is reset, the side of the inclined block 21 close to the rotating plate 20 is engaged with the right-angled side of the clamping block 23. At this time, the inclined block 21 is blocked by the clamping block 23, resulting in the rotating plate 20 being unable to move up and reset, and the fixing rod 15, the lifting rod 7 and the sponge 6 are unable to move up and reset, thereby realizing the function of the sponge 6 being retained. After the rotating disk 13 rotates a certain number of times, the protrusion 14 is Figure 4 From a viewing angle, the guide rod 22 is hit clockwise, and the guide rod 22 is swung by the force. The swing of the guide rod 22 drives the rotating plate 20 to rotate. The rotation of the rotating plate 20 drives the inclined block 21 to disengage from the engagement with the clamping block 23. At this time, the rotating plate 20 can be reset, and the sponge 6 can move up, ending its stay on the outside of the titanium alloy rod.

[0046] like Figure 7 , Figure 8 and Fig. 9 As shown, a pair of collecting plates 25 are provided on the outer side of the sponge 6, and a liquid outlet pipe 26 is installed on the side of the collecting plates 25 away from the sponge 6, and a hose is installed on the end of the liquid outlet pipe 26 away from the collecting plate 25, and a pair of limiting plates 27 are fixedly connected to both sides of the collecting plates 25, and a concave plate 28 is provided on the outer side of the limiting plates 27, and a pair of limiting round rods 29 are fixedly connected to the inner wall of the concave plates 28, and the pair of limiting round rods 29 both penetrate the limiting plates 27, and a support frame 30 is fixedly connected to the outer side of the concave plates 28, and one end of the support frame 30 away from the concave plate 28 is fixed to the inner side of the connecting frame 9, and a separation mechanism cooperating with the limiting plate 27 is provided on the periphery of the limiting plate 27, and the separation mechanism is used to separate the pair of collecting plates 25.

[0047] After the sponge 6 absorbs the coolant, if the coolant attached to it is not discharged in time, it is easy to cause the next adsorption to deteriorate. When the embodiment of the present invention is in use, in the initial state, the pair of collecting plates 25 are in a state of squeezing the sponge 6, so that the coolant inside the sponge 6 overflows and falls into the inside of the pair of collecting plates 25, and then is discharged into the inside of the hose through the liquid outlet pipe 26, and the coolant is transported to a designated position through the hose for recycling. As the lifting rod 7 moves downward, the lifting rod 7 will drive the separation mechanism to operate, and the operation of the separation mechanism will drive the limiting plates 27 fixed to the outside of the pair of collecting plates 25 to move in opposite directions. The movement of the limiting plates 27 drives the collection plates 25 to move. It should be noted that at the moment when the lifting rod 7 moves downward, the separation mechanism can drive the pair of collecting plates 25 to move. At this time, although the sponge 6 moves downward under the action of the lifting rod 7, Fig. 9 It can be seen from the viewing angle that there is a certain gap between the bottom end of the sponge 6 and the inner wall of the collecting plate 25. Therefore, when the sponge 6 moves downward and the pair of collecting plates 25 are opened, the sponge 6 has not yet touched the collecting plate 25, and the sponge 6 is made of flexible material, and the squeezing of the sponge 6 and the collecting plate 25 will not affect the sponge 6. The sponge 6 can automatically reset to the initial state after the squeezing is completed. The opening of the pair of collecting plates 25 can provide movement space for the sponge 6 to move down and fit the titanium alloy rod. The pair of collecting plates 25 will not interfere with the sponge 6. When the lifting rod 7 drives the sponge 6 to move up to a certain distance, the separation mechanism will drive the pair of collecting plates 25 to reset along the limiting round rod 29. After the sponge 6 is completely reset, the pair of collecting plates 25 just clamps the two sides of the sponge 6, squeezes out the coolant attached to the inside of the sponge 6, and discharges it through the liquid outlet pipe 26 and the hose.

[0048] like Figure 7 , Figure 8 and Fig. 9 As shown, the separation mechanism includes a pair of transmission plates 31, a pair of triangular blocks 32, a pair of guide plates 33 and a pair of second springs 34. The pair of transmission plates 31 are fixedly connected to the outer side of the lifting rod 7, the pair of triangular blocks 32 are respectively fixedly connected to the bottom ends of the pair of transmission plates 31, the pair of guide plates 33 are fixedly connected to the top ends of the pair of limit plates 27, one ends of the pair of second springs 34 are respectively fixedly connected to the pair of limit plates 27, and one ends of the pair of second springs 34 away from the limit plates 27 are fixedly connected to the inner wall of the concave plate 28.

[0049] When the lifting rod 7 moves downward, the transmission plate 31 is driven to move downward. When the transmission plate 31 moves downward, the guide plate 33 is squeezed by the triangular block 32. At this time, the inclined surface of the triangular block 32 squeezes the inclined surface of the guide plate 33, so that the guide plate 33 is forced to move. The movement of the guide plate 33 drives the collecting plate 25 to move through the limiting plate 27, thereby realizing the function of separating and opening a pair of collecting plates 25, providing a movable space for the movement of the sponge 6. In the process of the movement of the limiting plate 27, the limiting plate 27 squeezes the second spring 34, causing the second spring 34 to deform. , and generates elastic potential energy. When the lifting rod 7 drives the triangular block 32 to reset through the transmission plate 31, the triangular block 32 gradually breaks away from the squeezing of the guide plate 33, and the force on the second spring 34 gradually disappears. The second spring 34 then gradually releases the elastic potential energy, and cooperates with the upward movement of the triangular block 32, and gradually pushes the collecting plate 25 to reset through the limit plate 27. Finally, the lifting rod 7 is reset, the triangular block 32 is completely separated from the squeezing of the guide plate 33, and the second spring 34 completely releases the elastic potential energy, and pushes the collecting plate 25 to completely reset through the limit plate 27, thereby generating an extrusion force on the sponge 6.

[0050] like Fig.10 As shown, the inner walls of the pair of collecting plates 25 are fixedly connected with inclined plates 35, and the interior of the liquid outlet pipe 26 is provided with a filter screen, which is used to isolate waste chips and dust generated by milling.

[0051] When the coolant is inside the collecting plate 25, since the bottom end of the inner wall of the collecting plate 25 is in a flat state, this causes the coolant to enter the liquid outlet pipe 26 too slowly. The coolant needs to accumulate above the height of the liquid outlet pipe 26 before it can flow down, and the coolant below the height of the liquid outlet pipe 26 cannot be discharged through the liquid outlet pipe 26. When the embodiment of the present invention is in use, an inclined plate 35 is installed inside the collecting plate 25. At this time, the coolant accumulated inside the collecting plate 25 will flow down toward the low slope along the inclined plate 35, and the liquid outlet pipe 26 is just at the low slope of the inclined plate 35. The coolant inside the collecting plate 25 will accelerate to flow to the liquid outlet pipe 26, and the design of the filter net inside the liquid outlet pipe 26 can also isolate impurities and waste chips in the coolant, and perform preliminary filtration on the recovery of the coolant.

[0052] A method for preparing high-quality TC4 titanium alloy large-size bars, the method comprising the following steps:

[0053] S1, the clamping module 2 clamps and fixes the two ends of the titanium alloy rod, and the distance adjustment module 4 is connected to the milling cutter, and the distance adjustment module 4 controls the milling cutter to be close to the titanium alloy rod. At this time, the power module drives the clamping module 2 to rotate;

[0054] S2, the rotation of the clamping module 2 will drive the titanium alloy rod to rotate, and the rotation of the titanium alloy rod will generate friction with the milling cutter, so that the milling cutter mills the outer side of the titanium alloy rod, and the cooling pipe sprays coolant on the contact point between the milling cutter and the titanium alloy rod to reduce the temperature generated by the contact between the milling cutter and the titanium alloy rod;

[0055] S3, the driving module 3 can drive the distance adjustment module 4 to move horizontally, and the distance adjustment module 4 drives the milling cutter to move, so as to evenly mill different positions of the titanium alloy rod. When the milling cutter 5 contacts the titanium alloy rod, the transmission mechanism drives the lifting rod 7 to move downward along the inside of the limiting square tube 8. The downward movement of the lifting rod 7 will drive the sponge 6 to move downward and contact the titanium alloy rod.

[0056] S4, then under the action of the coil spring 10, the coil spring 10 releases elastic potential energy after deformation, driving the retention mechanism to operate, forcing the sponge 6 to remain stationary;

[0057] S5. As the titanium alloy rod rotates, the sponge 6 will absorb impurities and waste liquid along the position where the titanium alloy rod is milled, thereby preventing the chemical components in the coolant from adhering to the surface of the titanium alloy rod for a long time.

[0058] Working principle: The clamping module 2 clamps and fixes the two ends of the titanium alloy rod, and the distance adjustment module 4 is connected to the milling cutter. The distance adjustment module 4 controls the milling cutter to get close to the titanium alloy rod. At this time, the power module drives the clamping module 2 to rotate, and the rotation of the clamping module 2 will drive the titanium alloy rod to rotate. The rotation of the titanium alloy rod generates friction with the milling cutter, so that the milling cutter mills the outside of the titanium alloy rod, and the cooling pipe sprays coolant on the contact point between the milling cutter and the titanium alloy rod to reduce the temperature generated by the contact between the milling cutter and the titanium alloy rod. The driving module 3 can drive the distance adjustment module 4 to move horizontally, and the distance adjustment module 4 drives the milling cutter to move, so as to Different positions of the alloy rod are evenly milled, and when the milling cutter 5 contacts the titanium alloy rod, the transmission mechanism drives the lifting rod 7 to move downward along the inside of the limiting square tube 8, and the downward movement of the lifting rod 7 will drive the sponge 6 to move downward and contact the titanium alloy rod, and then under the action of the coil spring 10, the coil spring 10 releases elastic potential energy after deformation, driving the retention mechanism to operate, forcing the sponge 6 to remain stationary, and as the titanium alloy rod rotates, the sponge 6 will be along the position of the milling cutter of the titanium alloy rod, and adsorb impurities and waste liquid, thereby avoiding the chemical components in the coolant from adhering to the surface of the titanium alloy rod for a long time. It should be noted that , sponge 6 is a fireproof and flame-retardant sponge with fireproof and water-absorbing functions. When sponge 6 is stationary for a period of time, although there is the support of coolant, the surface of the titanium alloy rod will still have a certain temperature. At this time, the transmission mechanism will push the retention mechanism, and the retention mechanism will drive the coil spring 10 to deform again under the force, and end the restriction on the lifting rod 7. The transmission mechanism will drive the sponge 6 to rise and reset through the lifting rod 7, thereby avoiding the sponge 6 from being attached to the titanium alloy rod for a long time, causing the surface temperature to be too high and damaged. It should be noted that although the sponge 6 is under the action of the transmission mechanism and the retention mechanism, The sponge 6 and the titanium alloy rod are intermittently reciprocated up and down, and there is a certain period of contact gap between the sponge 6 and the titanium alloy rod. However, the area of ​​the sponge 6 is larger than the area of ​​the milling cutter, and the speed at which the driving module 3 drives the distance adjustment module 4 to move horizontally is slow. When the sponge 6 contacts the titanium alloy rod next time, the contact area can make up for the gap during the separation. As the driving module 3 drives the milling cutter to move and the sponge 6 to move reciprocally up and down through the distance adjustment module 4, the milling cutter evenly mills the outside of the titanium alloy rod, and the sponge 6 evenly cleans the coolant attached to the outside of the titanium alloy rod. Finally, the processed titanium alloy rod can be removed.

[0059] The clamping module 2, the driving module 3, the distance adjustment module 4 and the power module are all existing technologies in milling, and the technology is mature. The functions are briefly introduced in the article without elaborating too much;

[0060] When the motor 12 is running, it drives the turntable 13 to rotate. The rotation of the turntable 13 drives the protrusion 14 to rotate synchronously. As the turntable 13 rotates, the protrusion 14 reaches the position of the roller 16, and the inclined surface of the protrusion 14 squeezes the roller 16, so that the roller 16 is subjected to force, driving the fixed rod 15 to move downward, and the downward movement of the fixed rod 15 drives the sponge 6 to move downward through the lifting rod 7. During the downward movement of the lifting rod 7, the first fixed plate 17 is driven to squeeze the first spring 19, so that the first spring 19 is deformed and generates elastic potential energy, and the sponge 6 When the convex block 14 moves downward, it will fit with the surface of the titanium alloy rod. As the titanium alloy rod rotates, the sponge 6 will clean the surface of the titanium alloy rod. When the convex block 14 passes over the roller 16, the extrusion of the roller 16 by the convex block 14 ends. It should be noted that when the turntable 13 drives the convex block 14 to rotate, the convex block 14 will not hit the first fixed plate 17. The first spring 19 is no longer stressed at this time, and the elastic potential energy is released instantly, driving the lifting rod 7 to reset through the first fixed plate 17. The reset of the lifting rod 7 will drive the sponge 6 to reset and break away from the fit with the titanium alloy rod.

[0061] As the fixed rod 15 moves downward, the fixed rod 15 will synchronously drive the rotating plate 20 to move downward. As the rotating plate 20 moves downward, the rotating plate 20 drives the inclined surface of the inclined block 21 to contact the inclined surface of the clamping block 23. Since the position of the clamping block 23 is fixed, the inclined block 21 drives the rotating plate 20 to make a circular motion with the fixed rod 15 as the center. The movement of the rotating plate 20 will stretch the coil spring 10, causing the coil spring 10 to deform and generate elastic potential energy. When the inclined block 21 reaches the half position of the clamping block 23, the clamping block 23 ends its squeezing of the inclined block 21, and the coil spring 10 is stretched. When the spring 10 is no longer stressed, the elastic potential energy is released instantly, driving the rotating plate 20 to reverse and reset. The reverse reset of the rotating plate 20 will drive the inclined block 21 to reverse and reset. After the inclined block 21 is reset, the side of the inclined block 21 close to the rotating plate 20 is engaged with the right-angled side of the clamping block 23. At this time, the inclined block 21 is blocked by the clamping block 23, resulting in the rotating plate 20 being unable to move up and reset, and the fixing rod 15, the lifting rod 7 and the sponge 6 are unable to move up and reset, thereby realizing the function of the sponge 6 being retained. After the rotating disk 13 rotates a certain number of times, the protrusion 14 is Figure 4 From a viewing angle, the guide rod 22 is hit clockwise, and the guide rod 22 is swung by force, and the swing of the guide rod 22 drives the rotating plate 20 to rotate, and the rotation of the rotating plate 20 drives the inclined block 21 to disengage from the engagement with the clamping block 23. At this time, the rotating plate 20 can be reset, and the sponge 6 can move up, and stop being retained on the outside of the titanium alloy rod;

[0062] After the sponge 6 absorbs the coolant, if the coolant attached to it is not discharged in time, it is easy to cause the next adsorption to deteriorate. When the embodiment of the present invention is in use, in the initial state, the pair of collecting plates 25 are in a state of squeezing the sponge 6, so that the coolant inside the sponge 6 overflows and falls into the inside of the pair of collecting plates 25, and then is discharged into the inside of the hose through the liquid outlet pipe 26, and the coolant is transported to a designated position through the hose for recycling. As the lifting rod 7 moves downward, the lifting rod 7 will drive the separation mechanism to operate, and the operation of the separation mechanism will drive the limiting plates 27 fixed to the outside of the pair of collecting plates 25 to move in opposite directions. The movement of the limiting plates 27 drives the collection plates 25 to move. It should be noted that at the moment when the lifting rod 7 moves downward, the separation mechanism can drive the pair of collecting plates 25 to move. At this time, although the sponge 6 moves downward under the action of the lifting rod 7, Fig. 9 It can be seen from the perspective that there is a certain gap between the bottom end of the sponge 6 and the inner wall of the collecting plate 25. Therefore, when the sponge 6 moves downward and the pair of collecting plates 25 are opened, the sponge 6 has not yet contacted the collecting plate 25, and the sponge 6 is made of flexible material, and the squeezing of the sponge 6 and the collecting plate 25 will not affect the sponge 6. The sponge 6 can automatically reset to the initial state after the squeezing is completed. The opening of the pair of collecting plates 25 can provide a moving space for the sponge 6 to move downward and fit the titanium alloy rod. The pair of collecting plates 25 will not interfere with the sponge 6. When the lifting rod 7 drives the sponge 6 to move up to a certain distance, the separation mechanism will drive the pair of collecting plates 25 to reset along the limiting round rod 29. After the sponge 6 is completely reset, the pair of collecting plates 25 just clamp the two sides of the sponge 6, squeeze out the coolant attached to the inside of the sponge 6, and discharge it through the liquid outlet pipe 26 and the hose;

[0063] When the lifting rod 7 moves downward, the transmission plate 31 is driven to move downward. When the transmission plate 31 moves downward, the guide plate 33 is squeezed by the triangular block 32. At this time, the inclined surface of the triangular block 32 squeezes the inclined surface of the guide plate 33, so that the guide plate 33 is forced to move. The movement of the guide plate 33 drives the collecting plate 25 to move through the limiting plate 27, thereby realizing the function of separating and opening a pair of collecting plates 25, providing a movable space for the movement of the sponge 6. In the process of the movement of the limiting plate 27, the limiting plate 27 squeezes the second spring 34, causing the second spring 34 to deform. , and generates elastic potential energy. When the lifting rod 7 drives the triangular block 32 to reset through the transmission plate 31, the triangular block 32 gradually breaks away from the extrusion of the guide plate 33, and the force on the second spring 34 gradually disappears. The second spring 34 then gradually releases the elastic potential energy, and cooperates with the upward movement of the triangular block 32 to gradually push the collecting plate 25 to reset through the limit plate 27. Finally, the lifting rod 7 is reset, the triangular block 32 is completely separated from the extrusion of the guide plate 33, and the second spring 34 completely releases the elastic potential energy, and pushes the collecting plate 25 to completely reset through the limit plate 27, thereby generating an extrusion force on the sponge 6;

[0064] When the coolant is inside the collecting plate 25, since the bottom end of the inner wall of the collecting plate 25 is in a flat state, this causes the coolant to enter the liquid outlet pipe 26 too slowly. The coolant needs to accumulate above the height of the liquid outlet pipe 26 before it can flow down, and the coolant below the height of the liquid outlet pipe 26 cannot be discharged through the liquid outlet pipe 26. When the embodiment of the present invention is in use, an inclined plate 35 is installed inside the collecting plate 25. At this time, the coolant accumulated inside the collecting plate 25 will flow down toward the low slope along the inclined plate 35, and the liquid outlet pipe 26 is just at the low slope of the inclined plate 35. The coolant inside the collecting plate 25 will accelerate to flow to the liquid outlet pipe 26, and the design of the filter net inside the liquid outlet pipe 26 can also isolate impurities and waste chips in the coolant, and perform preliminary filtration on the recovery of the coolant.

Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
