[0033] The embodiment of the present application discloses a processing equipment and method of a porous diffuser.

The control member 4 further includes a controller which is connected with the frequency converter to cooperate with each other.
[0038] The electric control structure 2 is provided with a sensor group 23 which is connected with the drilling tool 3. The sensor group 23 is mainly used to monitor the working state of the drilling tool 3 in real time and transmit the working state data to the control member 4. The working state data includes the speed, pressure or temperature. The sensor group 23 is connected with the frequency converter to detect the drilling data information of the drilling tool 3 and transmit the data to the frequency converter. The frequency converter sends control instructions to the electric control structure 2 to control the speed fluctuation of the drilling tool 3.
[0039] Specifically, the drilling tool 3 is driven by the electric control structure 2 to rotate at high speed and contacts the surface of the diffuser. The drilling tool 3 drills the surface of the diffuser. However, the contact with the surface of the diffuser causes the drilling tool 3 to be subjected to a reaction force, which reduces the speed of the drilling tool 3. After the speed is reduced, the sensor group 23 monitors the speed data information and transmits the data to the control member 4. The frequency converter of the control member 4 provides a frequency signal to the electric control structure 2 to control the speed of the drilling tool 3 to reach the specified speed, thereby ensuring the stability of the speed during drilling and making the drilled hole wall smooth.
[0040] Further, referring to Figure 2As shown, the electric control structure 2 includes a main shaft motor 21 and a control console 22; the main shaft motor 21 is connected with the control console 22, the main shaft motor 21 extends a driving shaft 211, the driving shaft 211 is connected with the drilling tool 3, the main shaft motor 21 drives the drilling tool 3 to rotate at high speed through the driving shaft 211, the outer joint 12 is installed on the control console 22, so that the control line 13 can transmit data signals to the control component 4, the control console 22 is also provided with a liquid inlet 221, an oil inlet 222, an air inlet 223 and a plurality of signal interfaces 224, the signal interfaces 224 can be connected with the power output line of the driving shaft 211, the encoder signal output line and the like, the liquid inlet 221 and the oil inlet 222 can be respectively connected with the cooling liquid delivery pipe and the lubricating oil delivery pipe, so as to respectively deliver the cooling liquid and the lubricating oil to the drilling tool 3.
[0041] The main shaft motor 21 drives the drilling tool 3 through the driving shaft 211, so as to realize the high-speed rotation of the drilling tool 3 to provide accurate drilling for the diffuser, and the control console 22 can be connected with various driving elements through various interfaces, so as to improve the stability of drilling.
[0042] Further, referring to Figure 3 As shown, the sensor group 23 includes an encoder, a temperature sensor, a rotating speed sensor, an eddy current displacement sensor and a vibration sensor, the encoder is a high-resolution encoder, which is greater than or equal to 17 bits, the encoder is used for encoding and converting signals (such as bit streams) or data into a signal form available for communication, transmission and storage, and encoding and converting signals transmitted by the temperature sensor, the rotating speed sensor, the eddy current displacement sensor and the vibration sensor, and then transmitting the converted signals to the control component 4.
[0043] The temperature sensor can monitor the temperature change of the drilling tool 3 in the drilling process in real time, such as a PT100 sensor for the temperature of the driving shaft, and the rotating speed sensor can monitor the rotating speed of the drilling tool 3 in real time, the real-time rotating speed sensor feedback accuracy is ±0.02%, the eddy current displacement sensor is used for detecting the displacement and vibration of the drilling tool 3, and the frequency response is 8Mv / μm, these sensors are collectively referred to as the sensor group 23, which can read the position of the driving shaft 211 and the drilling tool 3, monitor the temperature to prevent overheating failure, change the instant rotating speed and manage the risk cutting position amplitude feedback.
[0044] Specifically, the data transmitted by the temperature sensor, the rotating speed sensor and the eddy current displacement sensor are analyzed by the encoder, and the data are converted into electrical signals and transmitted to the control component 4, so as to cooperate with the control component 4 to issue control instructions to the drilling tool 3, and improve the control accuracy.
[0045] In some embodiments, referring to Figure 3As shown, a cooling channel 212 is provided inside the drive shaft 211 of the spindle motor 21. The cooling channel 212 is connected to the liquid inlet 221. The drive shaft 211 is also provided with a cooling port 213 connected to the cooling channel 212. The liquid inlet 221 on the control console 22 is connected to the cooling channel 212. The liquid inlet 221 can be externally connected to a coolant delivery pipe and a delivery pump to deliver coolant to the liquid inlet 221. The coolant delivered by the liquid inlet 221 can be delivered to the drive shaft 211 and the drilling tool 3 through the cooling channel 212. The coolant is used to cool the high-speed rotating drive shaft 211 and the drilling tool 3 to reduce the impact of high temperature generated during drilling.
[0046] The drilling tool 3 has a water-cooling tank 31 inside, which is connected to the cooling port 213. After the coolant is transported through the cooling channel 212, it can enter the water-cooling tank 31. The water-cooling tank 31 expands the contact area between the coolant and the drilling tool 3, accelerates the heat exchange rate, and improves the cooling effect.
[0047] The control console 22 can be equipped with a drain port, and a drain pump can be installed at the drain port. A return water pipe is connected to the drain port in the water cooling tank 31, and the drain pump is used to extract the cooled water to the drain port.
[0048] The control console 22 can be equipped with a control bearing. The drive shaft 211 and the main spindle motor 21 can be separated. The drive shaft 211 is pivotally connected to the control bearing. Both the drive shaft 211 and the main spindle motor 21 can be equipped with meshing drive gears, so that the main spindle motor 21 can drive the drive shaft 211 to rotate through the drive gears. This method ensures that when the drive shaft 211 is connected to the liquid inlet 221, the water flow will not affect the main spindle motor 21. Other linkage methods can also be used, which will not be elaborated here.
[0049] In some embodiments, reference Figure 3 As shown, the water-cooling tank 31 is a V-shaped groove, and the drilling tool 3 is also provided with several liquid outlets 32. The liquid outlets 32 are connected to the water-cooling tank 31, and the liquid outlets 32 allow the coolant in the water-cooling tank 31 to be discharged from the liquid outlets 32. The purpose of the V-shaped groove in the water-cooling tank 31 is that when the drilling tool 3 rotates at high speed, the coolant in the water-cooling tank 31 will be subjected to centrifugal force and diffuse away from the axis. When the water-cooling tank 31 is a V-shaped groove, the tank wall is an inclined surface, which allows the coolant to diffuse along the inclined surface under the action of centrifugal force. The liquid outlets 32 are located at the top opening of the water-cooling tank 31, so the coolant can flow along the tank wall to the liquid outlets 32 under the action of centrifugal force and be discharged.
[0050] The bottom of the console 22 is also provided with a through cylinder 5, which is inserted with the driving shaft 211 and pivotally connected with the drilling tool 3. The pivotal connection can be that a sealing bearing 33 is arranged at the bottom of the through cylinder 5, and the drilling tool 3 rotates along the sealing bearing 33, and meanwhile, the water leakage is avoided.
[0051] The through cylinder 5 is provided with a spacing groove 51 and a liquid inlet 221. The liquid outlet 32 is communicated with the spacing groove 51 through the liquid inlet 221. The through cylinder 5 is used for receiving the cooling liquid discharged from the liquid outlet 32. The cooling liquid in the spacing groove 51 is used for secondary cooling. Since the through cylinder 5 covers a part of the driving shaft 211 and the drilling tool 3, when the cooling liquid is in the spacing groove 51, a certain heat exchange is provided, and the secondary cooling is realized.
[0052] When the liquid discharge pump and the recovery pipe are arranged, the recovery pipe can be arranged in the spacing groove 51. When the spacing groove 51 is full, the cooling liquid is recovered through the liquid discharge pump and the recovery pipe.
[0053] Specifically, the cooling liquid in the water cooling groove 31 is moved along the groove wall under the influence of the centrifugal force caused by the high-speed rotation of the drilling tool 3, so that the heat exchange with the drilling tool 3 is realized in the moving process, and the cooling efficiency is improved. The cooling liquid is discharged to the spacing groove 51 of the through cylinder 5 through the liquid outlet 32. The through cylinder 5 covers a part of the driving shaft 211 and the drilling tool 3, so that the cooling of the driving shaft 211 and the drilling tool 3 is provided from the outside by the gradually filled cooling liquid in the spacing groove 51, and the cooling efficiency is improved.
[0054] Since the drilling tool 3 rotates at high speed, the cooling liquid discharged from the liquid outlet 32 enters the spacing groove 51. When the cooling liquid in the spacing groove 51 gradually increases, the cooling liquid will overflow the liquid outlet 32. At this time, the cooling liquid will produce a certain backflow. However, due to the effect of the centrifugal force, the cooling liquid of the liquid outlet 32 will drive the cooling liquid in the spacing groove 51 to rotate synchronously, and the water flow vortex is formed. In this case, the cooling liquid can accelerate the flow speed and heat exchange speed in the drilling tool 3, so as to further improve the cooling efficiency.
[0055] Further, with reference to Figure 3 or Figure 4As shown, the bottom of the through-tube 5 is provided with a sealing bearing 33, the bottom of the sealing bearing 33 is provided with a flushing nozzle 6, and the flushing nozzle 6 penetrates the sealing bearing 33 and communicates with the spacing groove 51. A communication port can be formed in the sealing bearing 33 to communicate the spacing groove 51 with the flushing nozzle 6. The flushing nozzle 6 is used to receive the cooling liquid in the spacing groove 51. After receiving the cooling liquid, the flushing nozzle 6 will be opened by the increasing water pressure in the spacing groove 51, so that the cooling liquid is sprayed from the flushing nozzle 6. The flushing nozzle 6 is aligned with the outer wall of the drilling tool 3, so that the cooling liquid is sprayed to the outer wall of the drilling tool 3 to achieve external cooling, and reduce the sparks or sparks generated when the drilling tool 3 contacts the diffuser.
[0056] The nozzle of the flushing nozzle 6 is provided with a one-way valve. When the air pressure or water pressure in the spacing groove 51 is sufficient, the one-way valve is opened by the water pressure or air pressure, so that the flushing nozzle 6 is opened by the water pressure or air pressure, and the cooling liquid is sprayed to the drilling tool 3.
[0057] When the spacing groove 51 is filled with cooling liquid, the driving shaft 211 continues to add cooling liquid to increase the water pressure in the spacing groove 51, so that the flushing nozzle 6 is opened by the water pressure.
[0058] Further, referring to Figure 4 As shown, the console 22 is further provided with a pressure pump 225, the pressure pump 225 communicates with the air inlet 223, and the air inlet 223 communicates with the spacing groove 51. The pressure pump 225 is a small air pump. The pressure pump 225 is used to pressurize the spacing groove 51 through the air inlet 223, so that when the water pressure or air pressure is not enough, the pressure pump 225 provides a pressure boost to open the flushing nozzle 6 by the water pressure. At the same time, the water spraying force of the flushing nozzle 6 is different with different water pressure or air pressure. When the water spraying force is different, different effects can be achieved. For example, when the water spraying force is large, the surface of the drilling tool 3 can be washed, so that the surface of the drilling tool 3 is not attached with the debris generated by drilling. When the water spraying force is small, the position of the water spraying is lowered to the contact point of the drilling tool 3 and the diffuser, so that the cooling liquid is sprayed to the drilling position to prevent sparks or sparks.
[0059] Further, the through-tube 5 is further provided with a plurality of adjusting parts 52, the adjusting parts 52 are hinged with the flushing nozzle 6, the flushing nozzle 6 is located outside the through-tube 5 and is connected with the spacing groove 51 through a metal hose 61.
