Description

Technical Field

[0001] The present invention relates to the technical field of generator production, and specifically, to a milling device for aluminum cast end covers of generators. Background Art

[0002] The aluminum cast end cover of a generator is an important component of the generator, usually cast from aluminum alloy, and is divided into a front end cover and a rear end cover. Its core functions include fixing the rotor, stator, rectifier, and brush assembly, and at the same time, it has the functions of heat dissipation, magnetic leakage prevention, and weight reduction. After casting, the aluminum cast end cover needs to be precisely processed through a milling process to achieve precision control, machining of the sealing structure, and enhancement of the end cover functionality, and a milling device is required.

[0003] Currently, when the existing milling devices are in use, the following defects exist:

[0004] First, the output ends of some milling devices integrate different types of milling cutters to perform different forms of milling processing on the motor end cover, such as leveling, hole opening, or deburring, etc. And a blowing structure is arranged on the periphery of each milling cutter to blow away the aluminum chips on the milling cutter to prevent the chips from affecting the milling process of the end cover by the milling cutter. However, the blowing structure is generally fixed on the periphery of the milling cutter and cannot move. As a result, the blowing structure can often only blow away the aluminum chips at the milling end of the milling cutter and cannot blow away the aluminum chips adhered to other positions on the surface of the milling cutter, which may cause secondary cutting or scratching of the workpiece surface. The fixed blowing direction may also cause poor heat dissipation in a local area of the cutter, exacerbating wear; at the same time, the adhered aluminum chips may block the cutting edge, affecting the tool life;

[0005] Second, when one milling cutter performs milling processing on the motor end cover, the other milling cutters are in a non-working state, that is, the blowing structures near these milling cutters are in a shutdown state. As a result, the blowing effect of the blowing structure on the working milling cutter and the motor end cover being milled cannot be fully exerted, resulting in the possibility that the chips at the cutting position may not be fully blown away, causing chip accumulation, further shortening the tool life. In view of this, we propose a milling device for aluminum cast end covers of generators. Summary of the Invention

[0006] The present invention aims at the technical problems existing in the prior art and provides a milling device for aluminum cast end covers of generators to solve the problems that the blowing structure in the existing solution is generally fixed on the periphery of the milling cutter and cannot move, and that the other milling cutters in the existing solution are in a non-working state, that is, the blowing structures near these milling cutters are in a shutdown state, so that the blowing effect of the blowing structure on the working milling cutter and the motor end cover being milled cannot be fully exerted.

[0007] To achieve the above object, a milling processing device for the aluminum casting end cover of a generator includes a workbench. A first electric guide rail is fixedly arranged at the center of the top of the workbench. A clamping device is fixedly arranged at the output end of the first electric guide rail. A lifting frame is fixedly arranged at one end of the top of the workbench. A second electric guide rail is fixedly arranged at the output end of the lifting frame. A driving device for providing an axial force is fixedly arranged at the output end of the second electric guide rail. A rotating block is fixedly arranged at the output end of the driving device. Milling heads for milling the end cover are fixedly arranged on multiple sides of the rotating block. First adjusting mechanisms are symmetrically arranged on both sides of the connection between the rotating block and the milling head. The output end of the first adjusting mechanism is provided with a second adjusting mechanism, and it rotates along with the axial force perpendicular to the vertical plane generated by the first adjusting mechanism. An air guiding mechanism for flowing gas is arranged inside the second adjusting mechanism. The air guiding mechanism rotates along with the axial force generated by the rotation of the second adjusting mechanism and adjusts its length as the second adjusting mechanism expands and contracts itself. An air blowing mechanism for purging the milling heads and the end cover is arranged at the output end of the air guiding mechanism. The air blowing mechanism swings to generate an axial force and changes the air flow direction.

[0008] The beneficial effects of the present invention are as follows:

[0009] 1) By adjusting the length of the air guiding mechanism through the expansion and contraction of the second adjusting mechanism itself, the air blowing mechanism connected to the air guiding mechanism is driven to move, changing the position of the air blowing mechanism to change the blowing position. Then, combined with the axial force generated by the swing of the air blowing mechanism itself to change the air flow direction, the aluminum chips adhered to other positions on the surface of the milling head are fully blown away, avoiding secondary cutting or scratching the surface of the end cover, preventing poor heat dissipation in a local area of the milling head from aggravating wear, and preventing the cutting end from being blocked by aluminum chips, which is beneficial to extending the service life of the milling head.

[0010] 2) By rotating the second adjusting mechanism to generate an axial force and driving the air guiding mechanism and the air blowing mechanism to rotate, changing the orientation of the output end of the air blowing mechanism. Then, combined with the axial force generated by the rotation of the first adjusting mechanism to drive the second adjusting mechanism, the air guiding mechanism and the air blowing mechanism to rotate, the air blowing mechanism can be rotated to be close to the working milling head and the attached side of the end cover being milled, increasing the wind force intensity for blowing away the aluminum chips, fully dispersing the aluminum chips on the milling head and the motor end cover, avoiding the cutting end from being blocked by aluminum chips, which is beneficial to further extending the service life of the milling head.

[0011] On the basis of the above technical solution, the present invention can be further improved as follows:

[0012] As a further improvement of this technical solution, the air blowing mechanism includes a fixed frame. One end of the fixed frame is arranged on the second adjusting mechanism. A nozzle for spraying air is rotatably arranged inside the fixed frame. The input end of the nozzle is fixedly connected to a corrugated pipe. The end of the corrugated pipe away from the nozzle is connected to the air guiding mechanism.

[0013] The beneficial effect of adopting the above further solution is that the air guide mechanism sends compressed air into the bellows, and the compressed air then enters the air nozzle through the bellows and is ejected, thereby blowing away the aluminum chips on the milling head and the end cover.

[0014] As a further improvement of the technical solution, a first motor for generating axial force is fixedly mounted on a side of the fixing frame away from the rotating block, and an output end of the first motor passes through the fixing frame and is fixedly matched with a surface of the air nozzle.

[0015] The beneficial effect of adopting the above further scheme is that the reciprocating rotation of the first motor generates axial force, driving the air nozzle to swing back and forth. The bellows has a certain flexibility and can cooperate with the reciprocating swing of the air nozzle. It can continuously deliver the compressed gas delivered by the air guide mechanism to the air nozzle, and can continuously change the direction of the airflow ejected from the air nozzle, so that the airflow can blow in and out of the milling head surface and the end cover, fully blowing away aluminum debris adhered to other positions on the milling head surface, avoiding secondary cutting or scratching the end cover surface, and preventing poor heat dissipation in local areas of the milling head to aggravate wear. At the same time, it prevents aluminum chips from clogging the cutting end, which is beneficial to extending the life of the milling head.

[0016] As a further improvement of the present technical solution, the air guide mechanism includes an outer tube, the surface of the outer tube is connected to an air inlet pipe for inputting compressed gas, the inner wall of the outer tube is slidably provided with a folded tube, one end of the folded tube away from the outer tube is fixedly connected to one end of the corrugated tube, and the centers of the outer tube and the folded tube are both arranged on the second adjustment mechanism through a mounting frame.

[0017] The beneficial effect of adopting the above further scheme is that the compressed gas enters the outer tube through the air inlet pipe, continues to flow along the outer tube and the folded tube into the bellows, and continues to be ejected from the air nozzle to blow away the aluminum chips on the milling head and the end cover.

[0018] As a further improvement of the present technical solution, the second adjusting mechanism includes a mounting plate, one end of the mounting plate is fixedly arranged on the first adjusting mechanism, a second motor for providing axial force is fixedly arranged on the top of the mounting plate, the output end of the second motor passes through the mounting plate and is fixedly connected to the top end of the outer tube, and an annular groove is opened on the inner ring of the bottom of the mounting plate, and a rotating ring is slidably arranged in the annular groove.

[0019] The beneficial effect of adopting the above further scheme is that the rotation of the second motor generates axial force, which can drive the outer tube, folding tube, air nozzle and other structures to rotate, and can change the direction of the airflow ejected from the air nozzle; and when the outer tube rotates, it can drive other structures of the second adjustment mechanism used to install and fix the outer tube and folding tube to rotate.

[0020] As a further improvement of the technical solution, an outer plate is fixedly arranged at the bottom of the rotating ring, and the mounting bracket connected to the outer tube is fixedly arranged on the outer plate. A folded plate is slidably arranged on the inner wall of the outer plate, and the mounting bracket connected to the folded tube is fixedly arranged on the folded plate, and one end of the folded plate away from the outer plate is fixedly connected to one end of the fixed bracket.

[0021] The beneficial effect of adopting the above further solution is that when the folded plate slides along the inner wall of the outer plate, it can drive structures such as the folded tube, the fixed bracket and the air nozzle to move, so as to change the position of the airflow ejected by the air nozzle.

[0022] As a further improvement of the technical solution, a first connection block is fixedly arranged on the side of the outer plate away from the outer tube, a cylinder is fixedly arranged on one side of the first connection block, a second connection block is fixedly arranged at the output end of the cylinder, and one end of the second connection block is fixedly arranged on the folded plate.

[0023] The beneficial effect of adopting the above further solution is that when the cylinder extends or contracts itself, it can drive the first connection block to move, and then drive the folded plate to slide along the inner wall of the outer plate, and then drive the folded tube and the air nozzle to move, and then drive the position of the airflow ejected by the air nozzle to be close to or far from the milling head and the end cover, so as to fully blow and sweep the milling head and the end cover.

[0024] As a further improvement of the technical solution, the first adjustment mechanism includes a third motor, the end face of the third motor is fixedly arranged on the rotating block, a rotating shaft is fixedly arranged at the output end of the third motor, one end of the rotating shaft away from the third motor passes through the rotating block and is fixedly provided with an intermediate plate, and one end of the intermediate plate away from the rotating shaft is fixedly connected to one end of the mounting plate.

[0025] The beneficial effect of adopting the above further solution is that the third motor rotates to generate an axial force, drives the rotating shaft to rotate, and then drives the intermediate plate to rotate around the rotating shaft, and then drives structures such as the mounting plate, the outer tube, the folded plate and the air nozzle to rotate, so that the air nozzle is close to the working milling head and the side of the end cover being milled, and the wind force intensity for blowing away aluminum chips can be increased to avoid aluminum chip accumulation.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] The air blowing structure of the existing milling processing device is generally fixed on the periphery of the milling cutter and cannot move; other milling cutters of the existing milling processing device are in a non-working state, that is, the air blowing structures near these milling cutters are in a shutdown state, so that the blowing effect of the air blowing structure on the working milling cutter and the motor end cover being milled cannot be fully exerted.

[0039] Therefore, the present invention provides a milling processing device for the aluminum cast end cover of a generator. Please refer to Figures 1 - 9, which includes a workbench 1. At the center of the top of the workbench 1, a first electric guide rail is fixedly arranged. At the output end of the first electric guide rail, a jaw device 2 is fixedly arranged. The jaw device 2 includes a motor and a chuck. When the motor rotates, the chuck contracts or expands, so as to clamp and release the motor end cover. At one end of the top of the workbench 1, a lifting frame is fixedly arranged. At the output end of the lifting frame, a second electric guide rail is fixedly arranged. The lifting frame includes a driving source and a lead screw and other structures. When the driving source drives the lead screw to rotate forward or backward, the second electric guide rail can be driven to move along the vertical direction. Both the first electric guide rail and the second electric guide rail include a motor, a screw rod and a slider and other structures. The motor rotates to generate an axial force, drives the screw rod to rotate, and then drives the slider to move along the plane to generate a plane force. At the output end of the second electric guide rail, a driving device 3 for providing an axial force is fixedly arranged. At the output end of the driving device 3, a rotating block 4 is fixedly arranged. The driving device 3 includes a driving system and an equipment box. The driving system is arranged in the equipment box. The driving system rotates to generate an axial force and drives the rotating block 4 to rotate. At multiple sides of the rotating block 4, milling heads 5 for milling the end cover are fixedly arranged. On both sides of the connection between the rotating block 4 and the milling head 5, a first adjusting mechanism 6 is symmetrically arranged. At the output end of the first adjusting mechanism 6, a second adjusting mechanism 7 is arranged. And as the first adjusting mechanism 6 rotates with the axial force perpendicular to the vertical plane, inside the second adjusting mechanism 7, a gas guiding mechanism 8 for flowing gas is arranged. The gas guiding mechanism 8 rotates in cooperation with the axial force generated by the rotation of the second adjusting mechanism 7 and adjusts its length as the second adjusting mechanism 7 expands and contracts itself. At the output end of the gas guiding mechanism 8, a blowing mechanism 9 for purging the milling head 5 and the end cover is arranged. The blowing mechanism 9 swings to generate an axial force and changes the air flow direction. Among them:

[0040] As shown in the present invention Figures 1 - 2 shown, considering that the blowing mechanism 9 is generally fixed on the periphery of the milling head 5 and cannot move, resulting in that the blowing mechanism 9 can often only blow away the aluminum chips at the milling end of the milling head 5, and cannot blow away the aluminum chips adhered to other positions on the surface of the milling head 5, which may cause secondary cutting or scratching of the workpiece surface. The fixed blowing direction may also cause poor heat dissipation in a local area of the milling head 5, aggravating the wear; at the same time, the adhered aluminum chips may block the cutting edge, affecting the service life of the milling head 5. Therefore, as Figure 3 shown, by adjusting the length of the gas guiding mechanism 8 through the expansion and contraction of the second adjusting mechanism 7 itself, the blowing mechanism 9 communicated with the gas guiding mechanism 8 is driven to move, changing the position of the blowing mechanism 9 to change the blowing position. Then, in cooperation with the axial force generated by the swing of the blowing mechanism 9 itself to change the air flow direction, the aluminum chips adhered to other positions on the surface of the milling head 5 are fully blown away, avoiding secondary cutting or scratching the surface of the end cover, preventing poor heat dissipation in a local area of the milling head 5 from aggravating the wear, and at the same time preventing the aluminum chips from blocking the cutting end, which is beneficial to extending the service life of the milling head 5;

[0041] When one of the milling heads 5 mills the end cap, the other milling heads 5 are in a non-operating state, that is, the air blowing mechanism 9 near these milling cutters is in a shutdown state, so that the blowing effect of the air blowing mechanism 9 on the working milling head 5 and the milled end cap cannot be fully exerted, resulting in the possibility that the debris at the working position being cut may not be fully blown away, causing the debris to accumulate, further shortening the life of the milling head 5. Therefore, as Figure 3 shown, the second adjustment mechanism 7 rotates to generate an axial force and drives the air guiding mechanism 8 and the air blowing mechanism 9 to rotate, changing the orientation of the output end of the air blowing mechanism 9. Then, in cooperation with the first adjustment mechanism 6 rotating to generate an axial force, driving the second adjustment mechanism 7, the air guiding mechanism 8 and the air blowing mechanism 9 to rotate, so that the air blowing mechanism 9 rotates to be close to the side surface of the working milling head 5 and the milled end cap, which can increase the wind force intensity to blow away the aluminum chips, fully blow away the aluminum chips on the milling head 5 and the motor end cap, avoid the blockage of the cutting end by aluminum chips, and is beneficial to further extend the life of the milling head 5.

[0042] On the above basis, the specific structure is disclosed in detail:

[0043] To realize that the air in the air guiding mechanism 8 is blown into the air blowing mechanism 9 and ejected from the output end of the air blowing mechanism 9 to blow away the aluminum chips on the milling head 5 and the end cap, the specific structure of the air blowing mechanism 9 needs to be disclosed. Therefore, as Figure 3 shown, the air blowing mechanism 9 includes a fixing frame 91. One end of the fixing frame 91 is arranged on the second adjustment mechanism 7. A nozzle 92 for ejecting air is rotatably arranged inside the fixing frame 91. The input end of the nozzle 92 is fixedly communicated with a corrugated pipe 93. The end of the corrugated pipe 93 away from the nozzle 92 is communicated and arranged on the air guiding mechanism 8. Compressed air is sent into the corrugated pipe 93 through the air guiding mechanism 8, and then the compressed air enters the nozzle 92 through the corrugated pipe 93 and is ejected, so as to blow away the aluminum chips on the milling head 5 and the end cap.

[0044] Among them, to change the direction of the air flow ejected by the nozzle 92 and fully blow the aluminum chips adhering to the surface of the milling head 5 to avoid the accumulation of aluminum chips on the milling head 5 and the end cap, the specific structure of the air blowing mechanism 9 needs to be further disclosed. Therefore, as Figure 3 shown, a first motor 94 for generating an axial force is fixedly installed on the side of the fixing frame 91 away from the rotating block 4. The output end of the first motor 94 passes through the fixing frame 91 and is fixedly matched with the surface of the nozzle 92. By the reciprocating rotation of the first motor 94 to generate an axial force, the nozzle 92 is driven to reciprocate and swing, as Figure 8As shown, the bellows 93 has a certain flexibility and can cooperate with the nozzle 92 to swing back and forth, continuously conveying the compressed gas conveyed through the air guiding mechanism 8 to the nozzle 92, thereby continuously changing the direction of the air flow ejected from the nozzle 92, enabling the air flow to blow in and out the surface of the milling head 5 and the end cover, fully blowing away the aluminum chips adhered to other positions on the surface of the milling head 5, avoiding secondary cutting or scratching the surface of the end cover, preventing poor heat dissipation in local areas of the milling head 5 from aggravating wear, and preventing aluminum chips from blocking the cutting end, which is beneficial to extending the service life of the milling head 5.

[0045] Considering that the compressed gas needs to flow through the air guiding mechanism 8, enter the bellows 93, then enter the nozzle 92, and be ejected from the nozzle 92 to the milling head 5 and the end cover, it is necessary to disclose the specific structure of the air guiding mechanism 8. Therefore, as Figure 3 shown, the air guiding mechanism 8 includes an outer tube 81. An air inlet pipe 82 for inputting compressed gas is communicatively provided on the surface of the outer tube 81. The air inlet pipe 82 is externally connected to an air compressor, and the air compressor continuously compresses air and introduces it into the air inlet pipe 82. A folded tube 83 is slidably arranged on the inner wall of the outer tube 81. One end of the folded tube 83 away from the outer tube 81 is fixedly communicated with one end of the bellows 93. The centers of the outer tube 81 and the folded tube 83 are both arranged on the second adjusting mechanism 7 through a mounting bracket 84. The compressed gas enters the outer tube 81 through the air inlet pipe 82, continues to flow along the outer tube 81 and the folded tube 83 into the bellows 93, and continues to be ejected from the nozzle 92 to blow away the aluminum chips on the milling head 5 and the end cover.

[0046] Among them, to make the second adjusting mechanism 7 rotate to generate an axial force and drive structures such as the outer tube 81, the folded tube 83, and the nozzle 92 to rotate, it is necessary to disclose the specific structure of the second adjusting mechanism 7. Therefore, as Figure 3 shown, the second adjusting mechanism 7 includes a mounting plate 71. One end of the mounting plate 71 is fixedly arranged on the first adjusting mechanism 6. A second motor 72 for providing an axial force is fixedly arranged on the top of the mounting plate 71. The output end of the second motor 72 passes through the mounting plate 71 and is fixedly connected to the top end of the outer tube 81. An annular groove is formed in the inner circle at the bottom of the mounting plate 71, and a rotating ring 73 is slidably arranged in the annular groove. By rotating the second motor 72 to generate an axial force, structures such as the outer tube 81, the folded tube 83, and the nozzle 92 can be driven to rotate. As Figure 5 shown, the orientation of the air flow ejected from the nozzle 92 can be changed. When the outer tube 81 rotates, other structures of the second adjusting mechanism 7 for installing and fixing the outer tube 81 and the folded tube 83 can be driven to rotate.

[0047] Among them, to make the second adjusting mechanism 7 itself expand and contract, driving the folded tube 83 to slide along the inner wall of the outer tube 81 to change the position of the air flow ejected from the nozzle 92, it is necessary to disclose the specific structure of the second adjusting mechanism 7. Therefore, as Figure 3As shown in the figure, an outer plate 74 is fixedly arranged at the bottom of the rotating ring 73, and a mounting bracket 84 connected to the outer tube 81 is fixedly arranged on the outer plate 74. A folding plate 75 is slidably arranged on the inner wall of the outer plate 74, and a mounting bracket 84 connected to the folding tube 83 is fixedly arranged on the folding plate 75. One end of the folding plate 75 away from the outer plate 74 is fixedly connected to one end of the fixed bracket 91. By sliding the folding plate 75 along the inner wall of the outer plate 74, as Figure 7 shown, the structures such as the folding tube 83, the fixed bracket 91 and the air nozzle 92 can be driven to move, so as to change the position of the air flow ejected from the air nozzle 92.

[0048] Among them, to make the folding plate 75 slide along the inner wall of the outer plate 74 to drive the air nozzle 92 to move and change the position of the air flow, it is necessary to further disclose the specific structure of the second adjusting mechanism 7. Therefore, as Figure 3 shown, a first connecting block 76 is fixedly arranged on the side of the outer plate 74 away from the outer tube 81. A cylinder 77 is fixedly arranged on one side of the first connecting block 76. A second connecting block is fixedly arranged at the output end of the cylinder 77. One end of the second connecting block is fixedly arranged on the folding plate 75. By the cylinder 77 extending or shortening itself, as Figure 7 shown, the first connecting block 76 can be driven to move, and then the folding plate 75 can be driven to slide along the inner wall of the outer plate 74, and then the folding tube 83 and the air nozzle 92 can be driven to move, and then the position of the air flow ejected from the air nozzle 92 can be driven to be close to or far from the milling head 5 and the end cover, so as to blow the milling head 5 and the end cover sufficiently.

[0049] Among them, to make the first adjusting mechanism 6 rotate to generate an axial force to drive the structures such as the outer tube 81, the folding plate 75 and the air nozzle 92 to rotate, and rotate the air nozzle 92 to be close to the side of the working milling head 5 and the side of the end cover to be milled, so as to increase the wind force intensity of blowing away the aluminum chips, it is necessary to disclose the specific structure of the first adjusting mechanism 6. Therefore, as Figure 3 shown, the first adjusting mechanism 6 includes a third motor 61. The end face of the third motor 61 is fixedly arranged on the rotating block 4. A rotating shaft 62 is fixedly arranged at the output end of the third motor 61. One end of the rotating shaft 62 away from the third motor 61 passes through the rotating block 4 and is fixedly provided with an intermediate plate 63. One end of the intermediate plate 63 away from the rotating shaft 62 is fixedly connected to one end of the mounting plate 71. By the third motor 61 rotating to generate an axial force, the rotating shaft 62 is driven to rotate, and then the intermediate plate 63 is driven to rotate around the rotating shaft 62, and then the structures such as the mounting plate 71, the outer tube 81, the folding plate 75 and the air nozzle 92 are driven to rotate, so that the air nozzle 92 is close to the side of the working milling head 5 and the side of the end cover to be milled, and the wind force intensity of blowing away the aluminum chips can be increased to avoid the accumulation of aluminum chips.

[0050] In summary, the overall working principle of the present invention is as follows:

[0051] When it is necessary to use this milling device to mill the aluminum cast end cover of the generator, first place the generator end cover to be milled inside the jaw device 2, and start the jaw device 2 to firmly clamp the generator end cover. Drive the second electric guide rail, the driving device 3 and multiple milling heads 5 to move up and down through the lifting frame, then use the second electric guide rail to drive the driving device 3 and multiple milling heads 5 to move horizontally, and then use the first electric guide rail to drive the jaw device 2 and the motor end cover to move horizontally. Start the milling head 5 to rotate, and the milling operation of the milling head 5 on the motor end cover can be realized. In this process, start the first motor 94 on both sides of the working milling head 5 to rotate reciprocally to generate an axial force, drive the air nozzle 92 to swing reciprocally, and continuously change the direction of the airflow ejected from the air nozzle 92, so that the airflow can blow in and out of the surface of the milling head 5 and the end cover, and fully blow away the aluminum chips adhering to other positions on the surface of the milling head 5;

[0052] When it is necessary to replace different milling heads 5 to mill the generator end cover, start the driving device 3 to drive the rotating block 4 to rotate, and then drive different milling heads 5 to rotate, and rotate other milling heads 5 above the generator end cover. At this time, it is necessary to rotate the blowing mechanism 9 beside the non-working milling heads 5 on both sides of the milling head 5 for preparation work to both sides of the milling head 5 for preparation work and the generator end cover. Start the second motor 72 to rotate to generate an axial force, which can drive structures such as the outer tube 81, the folded tube 83 and the air nozzle 92 to rotate, and change the orientation of the airflow ejected from the air nozzle 92 so that it no longer faces the non-working milling head 5 directly opposite. Then start the third motor 61 to rotate to generate an axial force, drive the rotating shaft 62 to rotate self, and then drive the middle plate 63 to rotate around the rotating shaft 62 as the axis, and then drive structures such as the mounting plate 71, the outer tube 81, the folded plate 75 and the air nozzle 92 to rotate, so that the air nozzle 92 is close to the working milling head 5 and the attached side of the end cover being milled. Then start the air cylinder 77 to extend or shorten, which can drive the first connecting block 76 to move, and then drive the folded plate 75 to slide along the inner wall of the outer plate 74, and then drive the folded tube 83 and the air nozzle 92 to move, and then drive the position of the airflow ejected from the air nozzle 92 to be close to or far from the milling head 5 and the end cover, so that the air nozzle 92 moves to a suitable position, and then make the external airflow eject from the air nozzle 92 to blow the milling head 5 and the generator end cover sufficiently.
