Description

Technical Field

[0001] The invention relates to the technical field of nut processing equipment, and in particular to a high-speed rail nut side hole processing device and a use method thereof. Background Art

[0002] High-speed rail nuts refer to nuts used in high-speed railway track systems that withstand high strength and durability requirements. They are usually used to fix and connect connecting parts such as railway tracks, bridges, and vehicles to ensure the safety, stability, and long-term reliability of the high-speed rail system.

[0003] Among them, when processing the side holes of the nut, the size of the processed holes is often small, and the debris generated by the smaller holes is usually difficult to discharge in time. As the cutting depth of the drill bit increases, the debris may accumulate in the side hole, which may cause the drill bit to vibrate or deflect, deviate from the normal running trajectory, and affect the drilling quality. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a high-speed rail nut side hole processing device, including a drilling table, a connecting frame 1 is fixedly connected to the top of the drilling table, two clamping blocks are slidably connected to the top of the drilling table, threaded rods are rotatably connected to the side walls of the two clamping blocks, the outer walls of the two threaded rods are threadedly connected to the inner wall of the drilling table, a motor is fixedly connected to the top of the connecting frame 1, a gear 1 is fixedly connected to the bottom output end of the motor, a gear 2 is meshedly connected to the outer wall of the gear 1, and an air suction component is arranged on the inner wall of the connecting frame 1;

[0005] The drilling mechanism includes a rotating rod rotatably connected to the inner wall of the connecting frame 1, the outer wall of the rotating rod is fixedly connected to the inner wall of the gear 2, a sliding rod 1 is arranged on the inner wall of the connecting frame 1, a slider is fixedly connected to the outer wall of the sliding rod 1, the outer wall of the sliding rod 1 is slidably connected to the inner wall of the rotating rod through the slider, a connecting plate is rotatably connected to the outer wall of the sliding rod 1, the bottom of the connecting frame 1 is fixedly connected to an electric telescopic rod, the bottom output end of the electric telescopic rod is fixedly connected to the top of the connecting plate, the bottom of the sliding rod 1 is fixedly connected to a drill bit, and three water spray holes are opened on the inner wall of the drill bit;

[0006] The water spraying mechanism comprises a liquid storage tank fixedly connected to the top of the connecting frame 1, an extrusion plate is slidably connected to the inner wall of the liquid storage tank, a rotating rod is arranged on the inner wall of the sliding rod 1, six connecting rods are fixedly connected to the bottom of the rotating rod, and the bottoms of the six connecting rods are fixedly connected to the top of the rotating rod, a concave-convex ring is arranged on the top of the liquid storage tank, and the bottom of the concave-convex ring is fixedly connected to the top of the rotating rod, two spring return rods 1 are fixedly connected to the top of the liquid storage tank, and the tops of the two spring return rods 1 are slidably connected to the bottom of the concave-convex ring, an infusion pipe is connected through the inner wall of the liquid storage tank, a water inlet one-way valve is fixedly connected to the inner wall of the infusion pipe, and a pressurizing component is arranged on the inner wall of the liquid storage tank. The staff connects the infusion pipe with the water pump to transport the coolant into the liquid storage tank, and then places the nut to be processed on the drilling table, and then rotates the threaded rod to push the clamping block to move to clamp the nut. After the clamping is completed, the motor is started to drive the gear 1 to rotate, and the gear 2 is rotated through the gear 1, so that the rotating rod rotates. When the rotating rod rotates, the sliding rod is rotated through the slider to make the drill bit rotate, and then the electric telescopic rod is started to extend, pushing the connecting plate down, making the sliding rod down, making the drill bit down, close to the nut, and drilling the side of the nut. At the same time, when the rotating rod rotates, it will also drive the connecting rod to rotate, making the rotating rod rotate, so that the concave-convex ring rotates, making the contact surface between the spring return rod and the concave-convex ring change from concave to convex, so that the spring return rod is squeezed, accumulating rebound force, pushing the extrusion plate down, squeezing the coolant in the liquid storage tank, and when the spring return rod contacts the concave position of the concave-convex ring again, the rebound force of the spring return rod is released, so that the extrusion plate returns to its position, and so on and so forth, the squeezed coolant will be squeezed frequently, pass through the inner wall of the sliding rod and the rotating rod, and then enter the drill bit, and be sprayed out through the water spray hole, so that the coolant has a large impact force, which can flush out the debris generated when the drill bit is drilling, effectively preventing the accumulation of debris, thereby reducing the vibration of the drill bit.

[0007] Preferably, the air suction component includes a sliding groove opened on the inner wall of the connecting frame 1, a sliding ring is slidably connected to the inner wall of the sliding groove, two sliding rods 2 are fixedly connected to the top of the sliding ring, two connecting frames 2 are arranged on the top of the connecting frame 1, and the side walls of the two connecting frames 2 are fixedly connected to the outer wall of the spring return rod 1.

[0008] Preferably, the air suction assembly also includes two fixed frames fixedly connected to the top of the connecting frame one, the outer walls of the two fixed frames are rotatably connected to the rotating frames, the inner walls of the two rotating frames are slidably connected to the top of the sliding rod two, and the bottoms of the two connecting frames two are slidably connected to the inner walls of the rotating frames. When the spring reset rod one descends, it will also drive the connecting frame two to descend, push the rotating frame to rotate, make the rotating frame tilt, push the sliding rod two to rise, and make the sliding ring rise. After the sliding ring rises, negative pressure will be generated at the bottom of the sliding ring.

[0009] Preferably, the air intake assembly also includes three air intake pipes that are connected through the inner wall of the sliding rod. The outer walls of the three air intake pipes are rotatably connected to the inner wall of the sliding groove. As the sliding ring continues to rise, the sliding ring will separate from the air intake pipe, thereby eliminating the obstruction to the air intake pipe, and the negative pressure will enter the rotating rod through the air intake pipe, sucking the coolant in the rotating rod into the sliding groove. When the spring return rod returns to its position, the connecting frame will also return to its position, allowing the sliding ring to return, squeezing the coolant in the sliding groove, allowing the coolant to enter the sliding rod, and allowing the coolant in the sliding rod to generate impact force again.

[0010] Preferably, the boosting assembly includes two arc blocks 1 slidably connected to the inner wall of the liquid storage tank, the inner walls of the two arc blocks 1 are slidably connected to arc blocks 2, the side walls of the two arc blocks 2 are fixedly connected to the inner wall of the liquid storage tank, and the outer walls of the two arc blocks 1 are fixedly connected to spring return rods 2.

[0011] Preferably, the boost assembly also includes an inclined block 1 fixedly connected to the side walls of the sliding rod 2, the side walls of the two spring return rods 2 are fixedly connected to the inclined block 2, the outer wall of the liquid storage tank is fixedly connected to two fixed frames, the inner walls of the two fixed frames are slidably connected to sliding plates, and the side walls of the two sliding plates are fixedly connected to blocking blocks. When the sliding rod 2 rises, the inclined block 1 will be driven to rise, so that the inclined block 1 contacts the inclined surface of the inclined block 2. At this time, the inclined block 1 will squeeze the inclined block 2, so that the inclined block 2 moves toward the direction of the rotating rod, pushing the spring return rod 2 to move, so that the spring return rod 2 accumulates rebound force, and the spring return rod 2 will push the arc block 1 to move, so that the two arc blocks 1 are close to each other. Since the arc block 2 is stationary, when the two arc blocks 1 are close to each other, the aperture through which the coolant passes will become smaller, thereby making the impact force generated by the coolant stronger.

[0012] Preferably, the boost assembly also includes a push rod fixedly connected to the side wall of the sliding plate, the side walls of the two push rods are fixedly connected to the side wall of the inclined block two, the outer walls of the two blocking blocks are slidably connected to the inner wall of the fixed frame, the bottoms of the two fixed frames are connected with air pipes, the outer walls of the two air pipes are connected to the inner wall of the liquid storage tank, and five air inlet holes are opened on the top of the fixed frame. When the inclined block two moves toward the direction of the rotating rod, it will also drive the push rod to move, pushing the sliding plate to move, and when the sliding plate passes over the air inlet hole, the sliding plate will squeeze the gas in the fixed frame.

[0013] A method for using a high-speed railway nut side hole processing device comprises the following steps:

[0014] S1: Coolant sprays out from the side hole;

[0015] S2: secondary extrusion coolant;

[0016] S3: Increase the spray pressure of coolant.

[0017] The present invention has the following beneficial effects:

[0018] (1) When the present invention is used, the staff connects the infusion tube to the water pump to transport the coolant into the liquid storage tank, and then places the nut to be processed on the drilling table, and then rotates the threaded rod to push the clamping block to move and clamp the nut. After the clamping is completed, the motor is started to drive the gear 1 to rotate, and the gear 2 is rotated through the gear 1, so that the rotating rod rotates. When the rotating rod rotates, the sliding rod 1 is rotated through the slider to rotate the drill bit, and then the electric telescopic rod is started to extend, pushing the connecting plate down, allowing the sliding rod 1 to descend, allowing the drill bit to descend and approach the nut to drill the side of the nut. At the same time, when the rotating rod rotates, it will also drive the connecting rod to rotate, so that the rotating rod rotates. The concave-convex ring is thereby rotated, and the contact surface between the spring return rod 1 and the concave-convex ring changes from concave to convex, so that the spring return rod 1 is squeezed, accumulating rebound force, pushing the extrusion plate down, and squeezing the coolant in the liquid storage tank; when the spring return rod 1 contacts the concave position of the concave-convex ring again, the rebound force of the spring return rod 1 is released, allowing the extrusion plate to return to its original position, and so on and so forth, so that the squeezed coolant is frequently squeezed, passes through the inner walls of the sliding rod 1 and the rotating rod, and then enters the drill bit and is sprayed out through the water spray hole, so that the coolant generates a greater impact force, which can flush out the debris generated when the drill bit is drilling, effectively preventing the accumulation of debris, thereby reducing the vibration generated by the drill bit.

[0019] (2) When the spring return rod 1 descends, the present invention will also drive the connecting frame 2 to descend, push the rotating frame to rotate, make the rotating frame tilt, push the sliding rod 2 to rise, and make the sliding ring rise. After the sliding ring rises, negative pressure will be generated at the bottom of the sliding ring. As the sliding ring continues to rise, the sliding ring will be separated from the suction pipe, thereby eliminating the obstruction to the suction pipe. The negative pressure will enter the rotating rod through the suction pipe and suck the coolant in the rotating rod into the sliding groove. When the spring return rod 1 returns to its original position, the connecting frame 2 will also return to its original position, thereby allowing the sliding ring to return to its original position, squeezing the coolant in the sliding groove, allowing the coolant to enter the sliding rod 1, and allowing the coolant in the sliding rod 1 to generate an impact force again, effectively preventing the impact force generated by the coolant from being reduced when the extrusion plate returns to its original position, resulting in debris being difficult to be flushed out in time, which may increase the difficulty of subsequent cleaning.

[0020] (3) When the sliding rod 2 rises, the inclined surface block 1 will be driven to rise, so that the inclined surface block 1 contacts the inclined surface of the inclined surface block 2. At this time, the inclined surface block 1 will squeeze the inclined surface block 2, so that the inclined surface block 2 moves toward the rotating rod, pushing the spring return rod 2 to move, so that the spring return rod 2 accumulates the rebound force, and the spring return rod 2 will push the arc block 1 to move, so that the two arc blocks 1 are close to each other. Since the arc block 2 is stationary, when the two arc blocks 1 are close to each other, the aperture through which the coolant passes will become smaller, thereby making the impact force generated by the coolant It is stronger and effectively prevents part of the coolant from entering the sliding groove, reducing the amount of coolant, resulting in a reduction in the impact force of the coolant, affecting the impact on the debris. In addition: when the sliding rod 2 returns, the inclined surface block 2 is separated from the inclined surface of the arc block 1, and the rebound force of the spring return rod 2 is released, allowing the arc block 1 to return, thereby allowing the coolant to flow normally, avoiding the aperture from becoming smaller, and the coolant is difficult to replenish in time, so that the rotating rod coolant is not filled, resulting in the coolant sprayed out of the sliding groove can only replenish the rotating rod, and it is difficult to generate a large impact force.

[0021] (4) In the present invention, when the inclined plane block 2 moves toward the direction of the rotating rod, it will also drive the push rod to move, and push the sliding plate to move. When the sliding plate passes over the air inlet, the sliding plate will squeeze the gas in the fixed frame. At this time, the squeezed gas will be blocked by the blocking block. Since the movement of the sliding plate will also drive the blocking block to move, as the sliding plate continues to move, a gap will be left between the blocking block and the air pipe, and the gas will enter the liquid storage tank from the air pipe, spraying gas onto the coolant in the liquid storage tank, increasing the gas in the coolant. The injection of gas helps to improve the fluidity of the coolant, increase the flow rate and kinetic energy, and thus more effectively remove chips and debris. BRIEF DESCRIPTION OF THE DRAWINGS

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.

[0035] For example, see Figure 1 - Figure 5The present invention is a high-speed rail nut side hole processing device, comprising a drilling platform 1, a connecting frame 11 is fixedly connected to the top of the drilling platform 1, two clamping blocks 12 are slidably connected to the top of the drilling platform 1, threaded rods 13 are rotatably connected to the side walls of the two clamping blocks 12, and the outer walls of the two threaded rods 13 are threadedly connected to the inner wall of the drilling platform 1, a motor 14 is fixedly connected to the top of the connecting frame 11, a gear 15 is fixedly connected to the bottom output end of the motor 14, and a gear 2 16 is meshedly connected to the outer wall of the gear 15, and an air suction component 4 is arranged on the inner wall of the connecting frame 11;

[0036] The drilling mechanism 2 includes a rotating rod 21 rotatably connected to the inner wall of the connecting frame 11, the outer wall of the rotating rod 21 is fixedly connected to the inner wall of the gear 2 16, a sliding rod 22 is provided at the inner wall of the connecting frame 11, a slider is fixedly connected to the outer wall of the sliding rod 22, the outer wall of the sliding rod 22 is slidably connected to the inner wall of the rotating rod 21 through the slider, a connecting plate 23 is rotatably connected to the outer wall of the sliding rod 22, an electric telescopic rod 24 is fixedly connected to the bottom of the connecting frame 11, the bottom output end of the electric telescopic rod 24 is fixedly connected to the top of the connecting plate 23, a drill bit 25 is fixedly connected to the bottom of the sliding rod 22, and three water spray holes 251 are opened on the inner wall of the drill bit 25;

[0037] The water spray mechanism 3 includes a liquid storage tank 31 fixedly connected to the top of the connecting frame 11, a squeezing plate 311 is slidably connected to the inner wall of the liquid storage tank 31, a rotating rod 32 is arranged at the inner wall of the sliding rod 22, six connecting rods 321 are fixedly connected to the bottom of the rotating rod 32, and the bottoms of the six connecting rods 321 are fixedly connected to the top of the rotating rod 21, a concave-convex ring 33 is arranged on the top of the liquid storage tank 31, and the bottom of the concave-convex ring 33 is fixedly connected to the top of the rotating rod 32, and two spring return rods 34 are fixedly connected to the top of the liquid storage tank 31. The top is slidably connected to the bottom of the concave-convex ring 33, and a liquid infusion tube 35 is connected to the inner wall of the liquid storage tank 31, and a water inlet check valve 351 is fixedly connected to the inner wall of the liquid infusion tube 35. A booster component 5 is provided on the inner wall of the liquid storage tank 31. The staff connects the liquid infusion tube 35 to the water pump to transport the coolant into the liquid storage tank 31, and then places the nut to be processed on the drilling table 1, and then rotates the threaded rod 13 to push the clamping block 12 to move and clamp the nut. After the clamping is completed, the motor 14 is started to drive the gear 15 to rotate, and the gear 15 rotates the gear 2 16, so that The rotating rod 21 is rotated. When the rotating rod 21 rotates, the sliding rod 22 is rotated through the slider to rotate the drill bit 25, and then the electric telescopic rod 24 is started to extend, pushing the connecting plate 23 down, allowing the sliding rod 22 to drop, allowing the drill bit 25 to drop close to the nut, and drilling the side of the nut. At the same time, when the rotating rod 21 rotates, it will also drive the connecting rod 321 to rotate, allowing the rotating rod 32 to rotate, thereby rotating the concave-convex ring 33, so that the contact surface between the spring return rod 34 and the concave-convex ring 33 changes from concave to convex, so that the spring return rod 34 is squeezed, accumulating resilience, and pushing the nut. The movable extrusion plate 311 descends to squeeze the coolant in the liquid storage tank 31. When the spring return rod 34 contacts the recessed position of the concave-convex ring 33 again, the resilience of the spring return rod 34 is released to return the extrusion plate 311. This reciprocating process frequently squeezes the extruded coolant, passes through the inner walls of the sliding rod 22 and the rotating rod 21, and then enters the drill bit 25 and is sprayed out through the water spray hole 251, so that the coolant generates a greater impact force, which can flush out the debris generated when the drill bit 25 drills a hole, effectively preventing the accumulation of debris, thereby reducing the vibration generated by the drill bit 25.

[0038] For example 2, please refer to Figure 6 - Fig. 9 The present invention is a high-speed rail nut side hole processing device. On the basis of embodiment one, the suction component 4 includes a sliding groove 41 opened on the inner wall of the connecting frame 11, and a sliding ring 42 is slidably connected to the inner wall of the sliding groove 41. Two sliding rods 43 are fixedly connected to the top of the sliding ring 42. Two connecting frames 44 are arranged on the top of the connecting frame 11, and the side walls of the two connecting frames 44 are fixedly connected to the outer wall of the spring return rod 34.

[0039] The air suction assembly 4 also includes two fixed frames 45 fixedly connected to the top of the connecting frame 11, and the outer walls of the two fixed frames 45 are rotatably connected with the rotating frames 451. The inner walls of the two rotating frames 451 are slidably connected to the top of the sliding rod 43, and the bottoms of the two connecting frames 44 are slidably connected to the inner walls of the rotating frames 451. When the spring return rod 1 34 descends, it will also drive the connecting frame 44 to descend, push the rotating frame 451 to rotate, make the rotating frame 451 tilt, push the sliding rod 43 to rise, and make the sliding ring 42 rise. After the sliding ring 42 rises, negative pressure will be generated at the bottom of the sliding ring 42.

[0040] The air suction component 4 also includes three air suction pipes 46 that are connected through the inner wall of the sliding rod 22. The outer walls of the three air suction pipes 46 are rotatably connected to the inner wall of the sliding groove 41. As the sliding ring 42 continues to rise, the sliding ring 42 will separate from the air suction pipe 46, thereby eliminating the obstruction of the air suction pipe 46, and the negative pressure will enter the rotating rod 21 through the air suction pipe 46, and the coolant in the rotating rod 21 will be sucked into the sliding groove 41. When the spring return rod 34 returns to its position, the connecting frame 44 will also return to its position, so that the sliding ring 42 returns to its position, squeezing the coolant in the sliding groove 41, allowing the coolant to enter the sliding rod 22, so that the coolant in the sliding rod 22 can generate impact force again.

[0041] The booster assembly 5 includes two arc blocks 51 slidably connected to the inner wall of the liquid storage tank 31, the inner walls of the two arc blocks 51 are slidably connected to arc blocks 511, the side walls of the two arc blocks 511 are fixedly connected to the inner wall of the liquid storage tank 31, and the outer walls of the two arc blocks 51 are fixedly connected to spring return rods 512.

[0042] The booster assembly 5 also includes an inclined surface block 1 52 fixedly connected to the side wall of the sliding rod 2 43, and the side walls of the two spring return rods 2 512 are fixedly connected with the inclined surface block 2 53. The outer wall of the liquid storage tank 31 is fixedly connected with two fixed frames 54, and the inner walls of the two fixed frames 54 are slidably connected with sliding plates 541. The side walls of the two sliding plates 541 are fixedly connected with blocking blocks 543. When the sliding rod 2 43 rises, the inclined surface block 1 52 will be driven to rise, so that the inclined surface block 1 52 and the inclined surface block 2 53 At this time, the inclined surface block 1 52 will squeeze the inclined surface block 2 53, so that the inclined surface block 2 53 moves toward the rotating rod 32, pushing the spring return rod 2 512 to move, so that the spring return rod 2 512 accumulates the rebound force, and the spring return rod 2 512 will push the arc block 1 51 to move, so that the two arc blocks 1 51 are close to each other. Since the arc block 2 511 is stationary, when the two arc blocks 1 51 are close to each other, the aperture through which the coolant passes will become smaller, thereby making the impact force generated by the coolant stronger.

[0043] The boost assembly 5 also includes a push rod 542 fixedly connected to the side wall of the sliding plate 541, the side walls of the two push rods 542 are fixedly connected to the side wall of the inclined block 2 53, the outer walls of the two blocking blocks 543 are slidably connected to the inner wall of the fixed frame 54, the bottoms of the two fixed frames 54 are connected with air pipes 544, the outer walls of the two air pipes 544 are connected to the inner wall of the liquid storage tank 31, and five air inlet holes 55 are opened on the top of the fixed frame 54. When the inclined block 2 53 moves toward the rotating rod 32, it will also drive the push rod 542 to move, pushing the sliding plate 541 to move. When the sliding plate 541 passes over the air inlet hole 55, the sliding plate 541 will squeeze the gas in the fixed frame 54.

[0044] The method for using the high-speed rail nut side hole processing device comprises the following steps:

[0045] S1: Coolant sprays out from the side hole;

[0046] S2: secondary extrusion coolant;

[0047] S3: Increase the spray pressure of coolant.

[0048] A specific application of this embodiment is as follows: when the present invention is used, the staff connects the infusion tube 35 to the water pump to transport the coolant into the liquid storage tank 31, and then places the nut to be processed on the drilling table 1, and then rotates the threaded rod 13 to push the clamping block 12 to move and clamp the nut. After the clamping is completed, the motor 14 is started to drive the gear 15 to rotate, and the gear 15 is used to rotate the gear 2 16, so that the rotating rod 21 is rotated. When the rotating rod 21 rotates, the sliding rod 1 22 is rotated through the slider to rotate the drill bit 25, and then the electric telescopic rod 24 is started to extend, pushing the connecting plate 23 to descend, allowing the sliding rod 1 22 to descend, allowing the drill bit 25 to descend, close to the nut, and drilling the side of the nut. At the same time, when the rotating rod 21 rotates, it will also drive the connecting rod 321 to rotate, so that The rotating rod 32 rotates, thereby rotating the concave-convex ring 33, so that the contact surface between the spring return rod 34 and the concave-convex ring 33 changes from concave to convex, so that the spring return rod 34 is squeezed, and the resilience is accumulated, pushing the extrusion plate 311 down, squeezing the coolant in the liquid storage tank 31, and when the spring return rod 34 contacts the concave position of the concave-convex ring 33 again, the resilience of the spring return rod 34 will be released, so that the extrusion plate 311 returns to its original position, and so on and so forth, the squeezed coolant will be squeezed frequently, passing through the inner walls of the sliding rod 22 and the rotating rod 21, and then entering the drill bit 25, and being sprayed out through the water spray hole 251, so that the coolant generates a large impact force, and can flush out the debris generated when the drill bit 25 drills a hole, effectively preventing the accumulation of debris, thereby reducing the vibration generated by the drill bit 25;

[0049] The water inlet check valve 351 in the liquid delivery tube 35 prevents the coolant from flowing back into the liquid delivery tube 35 when the coolant is squeezed by the squeezing plate 311;

[0050] Secondly, when the spring return rod 34 descends, it will also drive the connecting frame 24 to descend, push the rotating frame 451 to rotate, make the rotating frame 451 tilt, push the sliding rod 24 to rise, and make the sliding ring 42 rise. After the sliding ring 42 rises, negative pressure will be generated at the bottom of the sliding ring 42. As the sliding ring 42 continues to rise, the sliding ring 42 will separate from the suction pipe 46, thereby canceling the obstruction of the suction pipe 46, and the negative pressure will enter the rotating rod 21 through the suction pipe 46, and the coolant in the rotating rod 21 will be sucked into the sliding groove 41. When the spring return rod 34 returns, the connecting frame 24 will also return, so that the sliding ring 42 returns, squeezes the coolant in the sliding groove 41, and allows the coolant to enter the sliding rod 22, so that the coolant in the sliding rod 22 generates an impact force again, effectively preventing the impact force generated by the coolant from being reduced when the extrusion plate 311 returns, resulting in the difficulty of the debris being flushed out in time, which may increase the difficulty of subsequent cleaning;

[0051] Secondly, when the sliding rod 2 43 rises, it will drive the inclined plane block 1 52 to rise, so that the inclined plane block 1 52 contacts the inclined plane of the inclined plane block 2 53. At this time, the inclined plane block 1 52 will squeeze the inclined plane block 2 53, so that the inclined plane block 2 53 moves toward the rotating rod 32, pushing the spring return rod 2 512 to move, so that the spring return rod 2 512 accumulates the rebound force, and the spring return rod 2 512 will push the arc block 1 51 to move, so that the two arc blocks 1 51 are close to each other. Since the arc block 2 511 is stationary, when the two arc blocks 1 51 are close to each other, the aperture through which the coolant passes will become smaller, thereby allowing the coolant to The impact force generated is stronger, which effectively prevents part of the coolant from entering the sliding groove 41, reduces the amount of coolant, and reduces the impact force of the coolant, affecting the impact on the debris. In addition, when the sliding rod 43 returns to its original position, the inclined surface block 53 is separated from the inclined surface of the arc block 1 51, and the rebound force of the spring return rod 512 is released, so that the arc block 1 51 returns to its original position, thereby allowing the coolant to flow normally, avoiding the aperture from becoming smaller, and the coolant is difficult to be replenished in time, so that the rotating rod 21 is not filled with coolant, resulting in the coolant sprayed out of the sliding groove 41 can only replenish the rotating rod 21, and it is difficult to generate a large impact force;

[0052] Secondly, when the inclined plane block 53 moves toward the rotating rod 32, it will also drive the push rod 542 to move, and push the sliding plate 541 to move. When the sliding plate 541 passes over the air inlet 55, the sliding plate 541 will squeeze the gas in the fixed frame 54. At this time, the squeezed gas will be blocked by the blocking block 543. Since the movement of the sliding plate 541 will also drive the blocking block 543 to move, as the sliding plate 541 continues to move, a gap will be left between the blocking block 543 and the gas pipe 544, and the gas will enter the liquid storage tank 31 from the gas pipe 544, spraying gas to the coolant in the liquid storage tank 31, so that the gas in the coolant increases. The injection of gas helps to improve the fluidity of the coolant, increase the flow rate and kinetic energy, and thus more effectively take away the chips and debris;

[0053] When the rebound force of the spring return rod 512 is released, the blocking block 543 returns to its position, and the push rod 542 also returns to its position, thereby returning the sliding plate 541 to its position, so that the air inlet hole 55 is connected to the interior of the fixed frame 54 again, and the gas is replenished in the fixed frame 54 through the air inlet hole 55.
