Description

Technical Field

[0001] The invention relates to the technical field of hardware processing equipment, in particular to a drilling machine for precision hardware processing and a use method thereof. Background Art

[0002] Hardware: Traditional hardware products, also known as "small hardware", refer to five metals: gold, silver, copper, iron and tin. They can be made into works of art or metal devices such as knives and swords through artificial processing. Hardware in modern society is more extensive, such as hardware tools, hardware parts, daily hardware, construction hardware and security products. Drilling machines are tools used for drilling, expanding holes, countersinking, tapping and other operations on metals, alloys, plastics and other materials.

[0003] Among them, when using a drilling machine to drill holes in softer materials in hardware, such as copper and silver, the cut chips tend to adhere to the drill bit. Since precision parts usually require higher processing accuracy, the chips adhere to the drill bit, causing the drill bit to wear faster and affect the processing accuracy. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a drilling machine for precision hardware processing, comprising a placing table, a connecting frame is fixedly connected to the top of the placing table, two clamping blocks are slidably connected to the top of the placing table, two threaded rods are threadedly connected to the inner wall of the placing table, the side walls of the two clamping blocks are rotatably connected to the side walls of the threaded rods, an electric telescopic rod is fixedly connected to the bottom of the connecting frame, the bottom output end of the electric telescopic rod is fixedly connected to the top of the sliding block, and the top of the sliding block is fixedly connected to a motor;

[0005] The drilling mechanism includes a rotating rod rotatably connected to the inner wall of the sliding block, a pulley 1 is fixedly connected to the outer wall of the rotating rod, a pulley 2 is fixedly connected to the bottom output end of the motor, a transmission belt is sleeved on the outer walls of the pulleys 1 and 2, a drill bit is fixedly connected to the bottom of the rotating rod, a connecting hole is opened on the inner wall of the drill bit, and a connecting groove is opened on the inner wall of the rotating rod;

[0006] The extrusion mechanism includes a liquid storage tank fixedly connected to the top of the sliding block, an extrusion plate is slidably connected to the inner wall of the liquid storage tank, a fixed ring is fixedly connected to the top of the rotating rod, and an extrusion ring is fixedly connected to the top of the extrusion plate. A connecting ring 1 is arranged at the bottom of the connecting frame, and the bottom of the connecting ring 1 is fixedly connected to the top of the extrusion ring, and a spherical rod is rotatably connected to the top of the fixed ring, and the bottom of the connecting ring 1 is rotatably connected to the top of the spherical rod. A delivery hose is connected through the outer wall of the liquid storage tank, and a water inlet check valve is fixedly connected to the inner wall of the delivery hose. A scratching assembly is arranged on the inner wall of the liquid storage tank, and the delivery hose is connected to the water pump to deliver coolant to the liquid storage tank. After that, the staff will work on the drilling hole. The workpiece is placed on the placement table, and then the threaded rod is rotated to push the clamping block to move and clamp the workpiece. After clamping, the electric telescopic rod is started to push the sliding block down, so that the rotating rod and the drill bit are lowered and close to the workpiece. At the same time, the motor is started to drive the second pulley to rotate, so that the transmission belt rotates, thereby rotating the pulley one, and rotating the rotating rod and the drill bit until the drill bit contacts the workpiece to drill a hole in the workpiece. At the same time, when the rotating rod rotates, it will also drive the fixed ring to rotate, so that the spherical rod rotates around the center of the fixed ring, and the ball of the spherical rod rotates at the top of the fixed ring and the bottom of the connecting ring one, the spherical rod will tilt, and the connecting ring one will be pulled by the spherical rod to move downward. Fig. 9 As shown, the connection ring will drop down and the extrusion ring will drop, so that the extrusion plate will drop down and squeeze the coolant in the liquid storage tank. As the fixed ring continues to rotate, the two balls of the spherical rod will be in a vertical state again, as shown in FIG. Figure 5 As shown, the coolant will be squeezed frequently by reciprocating like this. Since the coolant transported into the liquid storage tank will fill the liquid storage tank and the connecting groove, the squeezed coolant will spray out through the connecting hole, causing impact and contact with the workpiece. The coolant will splash back to the surface of the drill bit to rinse the surface of the drill bit, thereby reducing the debris attached to the surface of the drill bit, such as copper debris, aluminum debris, etc., reducing the impact of the debris on the drill bit, effectively reducing the wear rate of the drill bit, and maintaining good processing accuracy.

[0007] Preferably, the scratch assembly includes three connecting frames rotatably connected to the bottom of the inner wall of the liquid storage tank, a connecting rod 1 is fixedly connected to the outer wall of the rotating rod, the tops of the three connecting frames are fixedly connected to the bottom of the connecting rod 1, a concave and convex ring is fixedly connected to the inner wall of the liquid storage tank, and a reciprocating assembly is arranged on the inner wall of the liquid storage tank.

[0008] Preferably, the scratch assembly also includes a spring sliding plate slidably connected to the inner wall of the connecting frame, the inner walls of the three connecting frames are slidably connected with sliding frames, the side walls of the three spring sliding plates are rotatably connected with connecting rods, and the bottoms of the three sliding frames are rotatably connected to the inner walls of the three connecting rods. When the rotating rod rotates, the connecting rod will also be driven to rotate, thereby rotating the connecting frame and causing the spring sliding plate to rotate around the center of the rotating rod. When the spring sliding plate rotates and contacts the protruding position of the concave-convex ring, the spring sliding plate will be squeezed and move toward the rotating rod, while accumulating rebound force.

[0009] Preferably, the scratch assembly also includes a scratch ring slidably connected to the inner wall of the connecting groove, the top of the scratch ring is fixedly connected to the bottom of the three sliding frames, the outer walls of the three sliding frames are slidably connected to the inner wall of the connecting rod one, and a connecting ring two is provided on the outer wall of the rotating rod, the top of the three sliding frames are fixedly connected to the bottom of the connecting ring two, when the spring sliding plate moves toward the rotating rod, the connecting rod will rotate to lift the sliding frame, thereby allowing the connecting ring two to rise, scratching the inner wall of the connecting groove, cooperating with the connecting frame to rotate in the liquid storage tank to disturb the coolant, thereby effectively preventing the coolant from precipitating.

[0010] Preferably, the reciprocating assembly includes three fixed frames fixedly connected to the inner wall of the liquid storage tank, the inner walls of the three fixed frames are slidably connected with spring plates, the bottoms of the three spring plates are fixedly connected with connecting rod 2, and the bottoms of the three fixed frames are provided with two water inlet holes. When the sliding frame rises, it will drive connecting ring 2 to rise until connecting ring 2 contacts connecting rod 2, and connecting ring 2 will lift connecting rod 2, so that the spring plate rises and accumulates rebound force. When the spring plate rises, the coolant in the liquid storage tank will enter the fixed frame through the water inlet hole.

[0011] Preferably, the reciprocating assembly also includes a fixed ring fixedly connected to the outer wall of the liquid storage tank, a sliding ring is slidably connected to the inner wall of the fixed ring, three sliding rods are fixedly connected to the top of the sliding ring, the outer wall of the extrusion ring is fixedly connected to the side walls of the three sliding rods, and three air inlet holes are opened on the outer wall of the fixed ring. When the extrusion ring descends, the sliding rods will also be driven to descend, allowing the sliding ring to descend. When the sliding ring covers the air inlet holes, the sliding ring will squeeze the gas in the fixed ring.

[0012] Preferably, the reciprocating assembly also includes three air pipes that are connected to the bottom of the fixed ring, the inner wall of the liquid storage tank is connected to the outer walls of the three air pipes, the tops of the three spring plates are fixedly connected with inclined blocks, the inner wall of the liquid storage tank is slidably connected with three spring air blocking blocks, the outer walls of the three spring air blocking blocks are slidably connected to the bottom of the inner wall of the fixed ring, and the inner walls of the three air pipes are fixedly connected with air outlet one-way valves. At this time, the squeezed gas will be blocked by the air outlet one-way valve, and the gas pressure will increase. When the sliding ring squeezes the gas and the spring plate rises, the spring plate will drive the inclined block to rise, so that the inclined block contacts the spring air blocking block. Since the contact surfaces of the two are inclined surfaces, the inclined block will squeeze the spring air blocking block, so that the spring air blocking block moves away from the rotating rod. As the spring air blocking block continues to move, the spring air blocking block will block the air pipe. At this time, the inside of the fixed ring is in a sealed state, the sliding ring descends, and the gas pressure will increase again.

[0013] A method for using a drilling machine for precision hardware processing includes the following steps:

[0014] S1: Start the equipment: connect the power of the electric telescopic rod and the motor, and start the drilling machine;

[0015] S2: Workpiece clamping: The worker places the workpiece to be drilled on the placement table, and then rotates the threaded rod to push the clamping block to move and clamp the workpiece;

[0016] S3: Drilling: Start the electric telescopic rod to push the sliding block down, so that the rotating rod and the drill bit can be lowered close to the workpiece. At the same time, start the motor to drive the second pulley to rotate, so that the transmission belt rotates, thereby rotating the first pulley, rotating the rotating rod and the drill bit, until the drill bit contacts the workpiece, and drills the workpiece;

[0017] S4: Debris flushing: When the rotating rod rotates, it will also drive the fixed ring to rotate, so that the spherical rod rotates around the center of the fixed ring, and the ball of the spherical rod rotates on the top of the fixed ring and the bottom of the connecting ring 1. The spherical rod will tilt, and the connecting ring 1 will be pulled by the spherical rod and move downward. The descent of the connecting ring 1 will cause the extrusion ring to descend, thereby causing the extrusion plate to descend, squeezing the coolant in the liquid storage tank. The squeezed coolant will spray out through the connecting hole, generating impact and contact with the workpiece, and the coolant will splash back to the surface of the drill bit to flush the surface of the drill bit.

[0018] The present invention has the following beneficial effects:

[0019] (1) When the present invention is used, the delivery hose is connected to the water pump to deliver coolant into the liquid storage tank. After that, the worker places the workpiece to be drilled on the placement table, and then rotates the threaded rod to push the clamping block to move and clamp the workpiece. After the clamping is completed, the electric telescopic rod is started to push the sliding block down, so that the rotating rod and the drill bit are lowered and close to the workpiece. At the same time, the motor is started to drive the second pulley to rotate, so that the transmission belt rotates, thereby rotating the first pulley, and rotating the rotating rod and the drill bit until the drill bit contacts the workpiece to drill the workpiece. At the same time, when the rotating rod rotates, it will also drive the fixed ring to rotate, so that the spherical rod rotates around the center of the fixed ring, and the ball of the spherical rod rotates at the top of the fixed ring and the bottom of the connecting ring. The spherical rod will tilt, and the connecting ring will be pulled by the spherical rod to move downward. Fig. 9 As shown, the connection ring will drop down and the extrusion ring will drop, so that the extrusion plate will drop down and squeeze the coolant in the liquid storage tank. As the fixed ring continues to rotate, the two balls of the spherical rod will be in a vertical state again, as shown in FIG. Figure 5 As shown, the coolant will be squeezed frequently by reciprocating like this. Since the coolant transported into the liquid storage tank will fill the liquid storage tank and the connecting groove, the squeezed coolant will spray out through the connecting hole, causing impact and contact with the workpiece. The coolant will splash back to the surface of the drill bit to rinse the surface of the drill bit, thereby reducing the debris attached to the surface of the drill bit, such as copper debris, aluminum debris, etc., reducing the impact of the debris on the drill bit, effectively reducing the wear rate of the drill bit, and maintaining good processing accuracy.

[0020] (2) When the rotating rod of the present invention rotates, it will also drive the connecting rod 1 to rotate, thereby rotating the connecting frame and causing the spring sliding plate to rotate around the center of the rotating rod. When the spring sliding plate rotates and contacts the protruding position of the concave-convex ring, the spring sliding plate will be squeezed and move toward the rotating rod, while accumulating rebound force. When the spring sliding plate moves toward the rotating rod, it will cause the connecting rod to rotate and lift the sliding frame, thereby causing the connecting ring 2 to rise and scratch the inner wall of the connecting groove. The connecting frame rotates in the liquid storage tank to disturb the coolant, thereby effectively preventing the coolant from precipitating and accumulating sediment, which will cause the connecting hole to be blocked, reducing the impact force of the coolant spray, and affecting the impact on the drill bit surface.

[0021] When the sliding frame of the present invention rises, it will drive the connecting ring 2 to rise until the connecting ring 2 contacts the connecting rod 2. The connecting ring 2 will then lift the connecting rod 2, thereby allowing the spring plate to rise and accumulate rebound force. When the spring plate rises, the coolant in the liquid storage tank will enter the fixed frame through the water inlet hole. When the extrusion plate returns to its original position, the coolant injected by the delivery hose may be difficult to fill the interior of the liquid storage tank in time. When the spring sliding plate rotates to the concave position of the concave-convex ring again, the rebound force of the spring sliding plate will be released, allowing the spring sliding plate to return to its original position. The sliding frame will then descend, thereby allowing the connecting ring 2 to descend. At this time, the liquid extrusion pressure on the spring plate will be reduced, and the rebound force of the spring plate will be released, allowing the spring plate to return to its original position, squeezing the coolant in the fixed frame into the liquid storage tank again, increasing the liquid pressure in the liquid storage tank. This reciprocating process effectively prevents the pressure of the extrusion pressure on the liquid from decreasing when the extrusion plate returns to its original position, resulting in an intermittent decrease in the impact force of the coolant on the drill bit surface, thereby affecting the flushing of debris.

[0022] (4) When the extrusion ring of the present invention descends, it will also drive the sliding rod to descend, allowing the sliding ring to descend. When the sliding ring covers the air inlet, the sliding ring will squeeze the gas in the fixed ring. At this time, the squeezed gas will be blocked by the gas outlet one-way valve, and the gas pressure will increase. When the sliding ring squeezes the gas and the spring plate rises, the spring plate will drive the inclined block to rise, allowing the inclined block to contact the spring gas blocking block. Since the contact surfaces of the two are inclined surfaces, the inclined block will squeeze the spring gas blocking block, allowing the spring gas blocking block to move away from the rotating rod. As the spring gas blocking block continues to move, the spring gas blocking block will block the gas supply pipe. At this time, the interior of the fixed ring is in a sealed state, the sliding ring descends, and the gas pressure will increase again until the extrusion plate returns to its position, allowing the extrusion ring to return to its position. This allows the sliding rod to return to its original position, and the sliding ring to return to its original position. At this time, the extrusion pressure on the spring plate is reduced, the spring plate will drop, the inclined block will separate from the spring air block, and the resilience of the spring air block will release and return to its original position. At this time, although the return of the sliding ring will reduce the gas pressure in the fixed ring, the gas pressure in the fixed ring is still relatively high. When a gap leaks out between the spring air block and the air pipe during the return process, the gas in the fixed ring will enter the air pipe through the gap, and then enter the liquid storage tank through the air pipe. The injection of gas can speed up the flow rate of the coolant, thereby allowing the spring plate to squeeze the coolant in the fixed frame. When it enters the liquid storage tank again, the impact force of the coolant is increased, which effectively prevents the impact force of the squeezed coolant from being too small when the spring plate returns.

A connecting ring 34 is provided at the bottom of the connecting frame 11, and the bottom of the connecting ring 34 is fixedly connected to the top of the extrusion ring 35. A spherical rod 36 is rotatably connected to the top of the fixed ring 33, and the bottom of the connecting ring 34 is rotatably connected to the top of the spherical rod 36. A delivery hose 37 is connected through the outer wall of the liquid storage tank 31, and a water inlet check valve 371 is fixedly connected to the inner wall of the delivery hose 37. A scratch assembly 4 is provided on the inner wall of the liquid storage tank 31, and the delivery hose 37 is connected to the water pump to transport coolant into the liquid storage tank 31. Then the staff will The workpiece is placed on the placing table 1, and then the threaded rod 13 is rotated to push the clamping block 12 to move and clamp the workpiece. After the clamping is completed, the electric telescopic rod 15 is started to push the sliding block 14 down, so that the rotating rod 21 and the drill bit 25 are lowered and close to the workpiece.

[0040] For example 2, please refer to Figure 6 - Fig.10The present invention is a drilling machine for precision hardware processing. On the basis of embodiment one, the scratch assembly 4 includes three connecting frames 41 rotatably connected to the bottom of the inner wall of the liquid storage tank 31, a connecting rod 42 is fixedly connected to the outer wall of the rotating rod 21, the tops of the three connecting frames 41 are fixedly connected to the bottom of the connecting rod 42, a concave-convex ring 43 is fixedly connected to the inner wall of the liquid storage tank 31, and a reciprocating assembly 5 is arranged on the inner wall of the liquid storage tank 31.

When the rotating rod 21 rotates, the connecting rod 42 is also driven to rotate, so that the connecting frame 41 rotates, and the spring sliding plate 44 rotates around the center of the rotating rod 21. When the spring sliding plate 44 rotates and contacts the protruding position of the concave-convex ring 43, the spring sliding plate 44 will be squeezed and move toward the rotating rod 21, while accumulating rebound force.

[0042] The scratch assembly 4 also includes a scratch ring 47 slidably connected to the inner wall of the connecting groove 26, the top of the scratch ring 47 is fixedly connected to the bottom of the three sliding frames 46, the outer walls of the three sliding frames 46 are slidably connected to the inner wall of the connecting rod 1 42, and a connecting ring 2 48 is provided on the outer wall of the rotating rod 21, the top of the three sliding frames 46 are fixedly connected to the bottom of the connecting ring 2 48, when the spring sliding plate 44 moves toward the rotating rod 21, it will make the connecting rod 45 rotate and lift the sliding frame 46, so that the connecting ring 2 48 rises, scratches the inner wall of the connecting groove 26, cooperates with the connecting frame 41 to rotate in the liquid storage tank 31, disturbs the coolant, and effectively prevents the coolant from precipitating.

[0043] The reciprocating assembly 5 includes three fixed frames 51 fixedly connected to the inner wall of the liquid storage tank 31, and the inner walls of the three fixed frames 51 are slidably connected with spring plates 52. The bottoms of the three spring plates 52 are fixedly connected with connecting rods 2 53, and the bottoms of the three fixed frames 51 are provided with two water inlet holes 54. When the sliding frame 46 rises, it will drive the connecting ring 2 48 to rise until the connecting ring 2 48 contacts the connecting rod 2 53, and the connecting ring 2 48 will lift the connecting rod 2 53, so that the spring plates 52 rise and accumulate rebound force.

The outer walls of the three spring air blocking blocks 58 are slidably connected to the bottom of the inner wall of the fixed ring 55. The inner walls of the three air pipes 56 are fixedly connected with gas outlet one-way valves 561. At this time, the squeezed gas will be blocked by the gas outlet one-way valves 561, and the gas The body pressure will increase. When the sliding ring 551 squeezes the gas and the spring plate 52 rises, the spring plate 52 will drive the inclined plane block 57 to rise, so that the inclined plane block 57 contacts with the spring air blocking block 58. Since the contact surfaces of the two are inclined planes, the inclined plane block 57 will squeeze the spring air blocking block 58, so that the spring air blocking block 58 is away from the rotating rod 21. As the spring air blocking block 58 continues to move, the spring air blocking block 58 will block the gas supply pipe 56. At this time, the interior of the fixed ring 55 is in a sealed state, the sliding ring 551 drops, and the gas pressure will increase again.

[0047] The method of using the drilling machine for precision hardware processing includes the following steps:

[0048] S1: Start the equipment: turn on the power of the electric telescopic rod 15 and the motor 16, and start the drilling machine;

[0049] S2: Workpiece clamping: The worker places the workpiece to be drilled on the placement table 1, and then rotates the threaded rod 13 to push the clamping block 12 to move and clamp the workpiece;

[0050] S3: Drilling: Start the electric telescopic rod 15 to push the sliding block 14 downward, so that the rotating rod 21 and the drill bit 25 are lowered close to the workpiece. At the same time, start the motor 16 to drive the pulley 23 to rotate, so that the transmission belt 24 rotates, thereby rotating the pulley 1 22, and rotating the rotating rod 21 and the drill bit 25 until the drill bit 25 contacts the workpiece, and the workpiece is drilled;

[0051] S4: Debris flushing: When the rotating rod 21 rotates, it will also drive the fixed ring 33 to rotate, so that the spherical rod 36 rotates around the center of the fixed ring 33, and the ball of the spherical rod 36 rotates on its own at the top of the fixed ring 33 and the bottom of the connecting ring 34. The spherical rod 36 will tilt, and the connecting ring 34 will be pulled by the spherical rod 36 to move downward. The descent of the connecting ring 34 will cause the extrusion ring 35 to descend, thereby causing the extrusion plate 32 to descend, squeezing the coolant in the liquid storage tank 31. The squeezed coolant will be ejected through the connecting hole 251, generating an impact and contacting the workpiece, and the coolant will splash back to the surface of the drill bit 25 to flush the surface of the drill bit 25.

[0052] A specific application of this embodiment is as follows: when the present invention is used, the delivery hose 37 is connected to the water pump to deliver coolant into the liquid storage tank 31. Thereafter, the staff places the workpiece to be drilled on the placement table 1, and then rotates the threaded rod 13 to push the clamping block 12 to move and clamp the workpiece. After the clamping is completed, the electric telescopic rod 15 is started to push the sliding block 14 down, so that the rotating rod 21 and the drill bit 25 are lowered and close to the workpiece. At the same time, the motor 16 is started to drive the pulley 23 to rotate, so that the transmission belt 24 rotates, thereby rotating the pulley 1 22, and rotating the rotating rod 21 and the drill bit 25 until the drill bit 25 contacts the workpiece to drill the workpiece. At the same time, when the rotating rod 21 rotates, it will also drive the fixed ring 33 to rotate, so that the spherical rod 36 rotates around the center of the fixed ring 33, and the ball of the spherical rod 36 rotates at the top of the fixed ring 33 and the bottom of the connecting ring 1 34, the spherical rod 36 will tilt, and the connecting ring 1 34 will be pulled by the spherical rod 36 to move downward. Fig. 9 As shown, the connection ring 1 34 descends to make the extrusion ring 35 descend, thereby making the extrusion plate 32 descend, squeezing the coolant in the liquid storage tank 31. As the fixed ring 33 continues to rotate, the two balls of the ball rod 36 will be in a vertical state again, as shown in FIG. Figure 5 As shown, the coolant will be squeezed frequently by reciprocating. Since the coolant transported into the liquid storage tank 31 will fill the liquid storage tank 31 and the connecting groove 26, the squeezed coolant will be ejected through the connecting hole 251, and will impact and contact the workpiece. The coolant will splash back to the surface of the drill bit 25, and the surface of the drill bit 25 will be washed, thereby reducing the debris attached to the surface of the drill bit 25, such as copper debris, aluminum debris, etc., reducing the influence of the debris on the drill bit 25, effectively reducing the wear rate of the drill bit 25, and maintaining good processing accuracy;

[0053] Secondly, when the rotating rod 21 rotates, it will also drive the connecting rod 1 42 to rotate, so that the connecting frame 41 rotates, and the spring sliding plate 44 rotates around the center of the rotating rod 21. When the spring sliding plate 44 rotates and contacts the protruding position of the concave-convex ring 43, the spring sliding plate 44 will be squeezed and move toward the rotating rod 21, while accumulating resilience. When the spring sliding plate 44 moves toward the rotating rod 21, it will cause the connecting rod 45 to rotate and lift the sliding frame 46, so that the connecting ring 2 48 rises, scratches the inner wall of the connecting groove 26, and cooperates with the connecting frame 41 to rotate in the liquid storage tank 31 to disturb the coolant, thereby effectively preventing the coolant from precipitating and accumulating sediment, resulting in blockage of the connecting hole 251, reducing the impact force of the coolant injection, and affecting the impact on the surface of the drill bit 25;

[0054] Secondly, when the sliding frame 46 rises, it will drive the connecting ring 48 to rise until the connecting ring 48 contacts the connecting rod 53, and the connecting ring 48 will lift the connecting rod 53, so that the spring plate 52 rises and accumulates the rebound force. When the spring plate 52 rises, the coolant in the liquid storage tank 31 will enter the fixed frame 51 through the water inlet hole 54. When the extrusion plate 32 returns to its original position, the coolant injected by the delivery hose 37 may be difficult to fill the liquid storage tank 31 in time, and when the spring sliding plate 44 rotates to the concave position of the concave-convex ring 43 again, the spring sliding plate 44 will be rotated to the concave position of the concave-convex ring 43. The resilience of the plate 44 will be released, allowing the spring sliding plate 44 to return to its original position, and the sliding frame 46 will drop, thereby causing the second connecting ring 48 to drop. At this time, the liquid squeezing force on the spring plate 52 will be reduced, and the resilience of the spring plate 52 will be released, allowing the spring plate 52 to return to its original position, squeezing the coolant in the fixed frame 51 into the liquid storage tank 31 again, increasing the liquid pressure in the liquid storage tank 31, and so on, effectively preventing the pressure of the squeezing force on the liquid from decreasing when the squeezing plate 32 returns to its original position, causing the impact force of the coolant on the surface of the drill bit 25 to decrease intermittently, affecting the flushing of the debris;

[0055] Secondly, when the extrusion ring 35 descends, it will also drive the sliding rod 552 to descend, allowing the sliding ring 551 to descend. When the sliding ring 551 covers the air inlet hole 553, the sliding ring 551 will squeeze the gas in the fixed ring 55. At this time, the squeezed gas will be blocked by the gas outlet one-way valve 561, and the gas pressure will increase. When the sliding ring 551 squeezes the gas and the spring plate 52 rises, the spring plate 52 will drive the inclined surface block 57 to rise, allowing the inclined surface block 57 to contact the spring gas blocking block 58. Since the contact surfaces of the two are inclined surfaces, the inclined surface block 57 will squeeze the spring gas blocking block 58, allowing the spring gas blocking block 58 to move away from the rotating rod 21. As the spring gas blocking block 58 continues to move, the spring gas blocking block 58 will block the gas supply pipe 56. At this time, the interior of the fixed ring 55 is in a sealed state, the sliding ring 551 descends, and the gas pressure will increase again until the extrusion plate 32 returns to its original position, allowing the extrusion The ring 35 returns to its original position, thereby allowing the sliding rod 552 to return to its original position, and allowing the sliding ring 551 to return to its original position. At this time, the squeezing force on the spring plate 52 is reduced, the spring plate 52 will drop, the inclined block 57 will separate from the spring air blocking block 58, and the resilience of the spring air blocking block 58 will release and return to its original position. At this time, although the return of the sliding ring 551 will reduce the gas pressure of the fixed ring 55, the gas pressure in the fixed ring 55 is still relatively high. When a gap leaks out between the spring air blocking block 58 and the air pipe 56 during the return process, the gas in the fixed ring 55 will enter the air pipe 56 through the gap, and then enter the liquid storage tank 31 through the air pipe 56. The injection of gas can accelerate the flow rate of the coolant, thereby allowing the spring plate 52 to squeeze the coolant of the fixed frame 51. When entering the liquid storage tank 31 again, the impact force of the coolant is increased, effectively preventing the impact force of the squeezed coolant from being small when the spring plate 52 returns to its original position;

[0056] When the two balls of the spherical rod 36 are vertical, the extrusion ring 35 will rise back to its original position, thereby returning the sliding rod 552 and the sliding ring 551 to their original positions, allowing the air inlet 553 to be connected with the interior of the sliding ring 551 again, and replenishing the gas in the fixed ring 55.
