Description

Technical Field

[0001] The present application relates to the technical field of numerically controlled machine tools, and in particular to a chip removal mechanism for a high-precision aircraft engine blade processing machine tool. Background Art

[0002] The shape of aircraft engine blades is complex and requires high processing precision, so the processing of aircraft engine blades is usually carried out on five-axis linkage machine tools. Five-axis linkage machine tools are high-end CNC machine tools. Five-axis linkage means that there are at least five coordinate axes on a machine tool, namely three linear coordinates and two rotational coordinates. Therefore, five-axis linkage machine tools have high processing efficiency and precision. The workpiece can be clamped once to complete the processing of multiple surfaces. Equipped with high-end CNC systems, complex spatial surfaces can be processed with high precision, thus processing aircraft blades that meet the precision requirements.

[0003] Five-axis machine tools are typically equipped with a chip conveyor, which collects the various metallic and non-metallic debris generated by the machine. The chip conveyor consists of a conveyor belt installed at the bottom of the machine tool's interior, and a collection cart located outside. Chips generated during machining fall onto the conveyor belt, which then transports them to the collection cart, completing the chip removal process. This prevents accumulation within the machine tool and ensures proper operation.

[0004] Regarding the above-mentioned related technologies, during machine tool processing, some debris falls directly onto the conveyor belt at the bottom of the machine tool, and some debris falls onto the machine tool bed and worktable surface. After the machine tool processing is completed, the operator needs to use a handheld brush to brush off the debris on the bed and worktable surface; since there are often tools or fixtures installed on the worktable, the worktable surface is not a regular plane, and the cleaning process is inconvenient. In addition, the surface temperature of the tool in the machine tool that has just finished working is high, and the operator is prone to accidentally touch it and cause burns when cleaning with a handheld brush. Summary of the Invention

[0005] In order to make it easier to clean the debris on the worktable surface of the machine tool, the present application provides a chip removal mechanism for a high-precision aircraft engine blade processing machine tool.

[0006] The chip removal mechanism of a high-precision aero-engine blade machining machine provided in this application adopts the following technical solution:

[0007] A chip removal mechanism for a high-precision aircraft engine blade processing machine tool is arranged inside the machine tool, and the machine tool includes a base and a bed arranged in the base. The chip removal mechanism includes a linear drive component and an air supply component arranged on the base, a support rod arranged at the output end of the linear drive component, and an exhaust duct arranged on the support rod. The moving direction of the output end of the linear drive component is parallel to the width direction of the bed, the support rod is arranged along the length direction of the bed, the exhaust duct is located on the top side of the bed, the air outlet of the exhaust duct faces the bed, and the end of the exhaust duct away from the air outlet is connected to the output end of the air supply component.

[0008] By adopting the above technical solution, the linear drive component drives the exhaust duct to move back and forth, and the exhaust duct can blow air toward the surface of the bed and the workbench, thereby blowing off the debris on the surface of the bed and the workbench, and avoiding the accumulation of debris on the workbench surface. Therefore, the debris cleaning process is simpler and does not require the operator to contact the workbench surface, thereby reducing the possibility of the staff being burned during cleaning, and is safer.

[0010] By adopting the above technical solution, since there are multiple exhaust ducts, the air outlet of each exhaust duct is smaller, so that the wind force is more concentrated, it is easier to blow off the debris, and the chip removal effect is better; the connecting block can adjust the position of the exhaust duct along the height direction of the bed, so the position of each connecting block can be adjusted according to the actual situation of the workbench surface of the bed. While ensuring the blowing effect, the exhaust duct can be avoided when moving to avoid collision between the exhaust duct and the fixture or tool on the workbench surface, which helps to smoothly carry out the chip removal process.

[0011] Optionally, the exhaust duct is rotatably arranged on a connecting block, the rotation axis of the exhaust duct is parallel to the support rod, the connecting block is respectively provided with a first magnet and a second magnet on both sides of the exhaust duct, and the exhaust duct is provided with a locking magnet. When the exhaust duct rotates to both sides, the first magnet and the second magnet can be attracted to the locking magnet respectively, and a pushing member is provided at both ends of the base in the width direction of the bed. When the exhaust duct moves to one side of the pushing member, the pushing member is used to push the exhaust duct to rotate.

[0012] By adopting the above technical solution, under normal circumstances, the locking magnet on the exhaust tube is attracted to the first magnet or the second magnet, so that the exhaust tube is in a tilted state, which helps to enhance the blowing effect of the exhaust tube and makes it easier to blow away debris; when the exhaust tube moves to one end of the base, the pushing member pushes the exhaust tube to rotate, so that the exhaust tube is converted to another tilted state and then moves in the opposite direction, so that the air outlet of the exhaust tube can always be tilted in the moving direction of the exhaust tube, which helps to ensure the blowing effect.

[0013] Optionally, a conveyor belt is provided in the base on at least one side of the bed, the conveyor belt is provided along the length direction of the bed, and a collection box is provided in the base at the conveying end of the conveyor belt.

[0014] By adopting the above technical solution, the debris falling from the bed and the workbench surface will fall onto the conveyor belt, and the conveyor belt can transport the debris to the collection box, so that the debris can be collected and cleaned up in a unified manner.

[0015] Optionally, guide plates are provided on both sides of the conveyor belt and at one end of the conveyor belt away from the collecting box, and the guide plates are arranged to be inclined downward from the side away from the conveyor belt to the side close to the conveyor belt.

[0016] By adopting the above technical solution, the setting of the guide plate can prevent debris from falling to both sides of the conveyor belt, so that the debris can fall onto the surface of the conveyor belt or directly into the collection box, thereby reducing the possibility of debris accumulating on the base at the bottom of the conveyor belt, thereby reducing the need to clean the base.

[0017] Optionally, a wiping assembly is provided in the base, and the wiping assembly includes a first power member, a roller and first bristles. The first power member is provided at one end of the conveyor belt close to the collection box. The roller is rotatably provided at one end of the conveyor belt close to the collection box and is transmission-connected to the first power member. The axis of the roller is parallel to the width direction of the conveyor belt. The first bristles are provided on the roller and the first bristles close to the side of the conveyor belt abut against the surface of the conveyor belt.

[0018] By adopting the above technical solution, the first power member drives the roller to rotate, and the first bristles on the roller can clean the surface of the conveyor belt, and clean the debris and coolant adhering to the surface of the conveyor belt into the collection box, thereby reducing the possibility of the debris adhering to the surface of the conveyor belt moving to the bottom of the conveyor belt and falling onto the base.

[0019] Optionally, a motor is connected to one side of one of the pulleys of the conveyor belt, and the first power member includes a driving gear coaxially connected to the motor output shaft and a driven gear coaxially connected to the roller, and the driven gear is meshed with the driving gear.

[0020] By adopting the above technical solution, when the motor drives the conveyor belt to operate, the driving gear and the driven gear can be used to drive the roller to rotate, thereby cleaning the surface of the conveyor belt.

[0021] Optionally, a filter is provided at the opening of the collection box, a pump body is provided outside the collection box, the liquid inlet of the pump body is connected to the inside of the collection box, a chip box is provided on one side of the collection box in the base, a cleaning assembly is provided on the top of the filter, the cleaning assembly includes a second power member, a conveyor belt and a brush plate, the second power member is provided at one end of the conveyor belt close to the collection box, the conveyor belt is transmission-connected to the second power member, the conveying end of the conveyor belt is located at the top of the chip box, the brush plate is provided on the belt surface of the conveyor belt, and the brush plate on the side of the conveyor belt close to the filter abuts against the filter.

[0022] By adopting the above technical solution, the arrangement of the filter screen and the pump body allows the coolant that falls into the collection box to be recycled after filtration, which can reduce the waste of coolant and reduce the cost of use; when working, the second power member drives the conveyor belt to operate, and the brush plate on the conveyor belt moves with the operation of the conveyor belt, so the brush plate at the bottom of the conveyor belt can continuously brush the debris that falls on the surface of the filter screen into the chip collection box, avoiding the accumulation of debris on the filter screen and causing the filtering effect of the filter screen to be weakened.

[0023] Optionally, a motor is connected to one side of one of the pulleys of the conveyor belt, and the second power member includes a driving bevel gear coaxially connected to the motor output shaft and a driven bevel gear coaxially connected to one of the pulleys of the conveyor belt, and the driving bevel gear and the driven bevel gear are meshed with each other.

[0024] By adopting the above technical solution, when the conveyor belt is running, the driving bevel gear and the driven bevel straight wheel can drive the conveyor belt to run, so no additional power source is required, which helps to save energy and reduce costs.

[0025] Optionally, a spray pipe is provided on the exhaust cylinder, the openings of the spray pipe and the exhaust cylinder are oriented in the same direction, and one end of the spray pipe away from the opening is connected to the liquid outlet of the pump body.

[0026] By adopting the above technical solution, when the exhaust duct blows air to the surface of the bed, the spray pipe can spray coolant to the surface of the bed, thereby further cleaning the debris on the surface of the bed and the workbench, helping to enhance the cleaning effect and ensure the smooth operation of the machine tool.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. After the machine tool is finished working, the linear drive component drives the exhaust duct to move back and forth, and the exhaust duct blows air to the surface of the bed and the worktable, thereby blowing off the debris on the surface of the bed and the worktable, so that the next processing of the machine tool can proceed smoothly, and the debris cleaning process is easier.

[0029] 2. When the exhaust duct moves, the air outlet of the exhaust duct tilts downward toward the bed, so the exhaust duct can more easily blow off the debris on the surface of the workbench, which helps to enhance the cleaning effect of the debris.

[0030] 3. When the conveyor belt is running, the motor drives the roller to rotate through the cooperation of the driving gear and the driven gear, and the roller drives the first brush to rotate. The first brush can clean the debris adhering to the surface of the conveyor belt into the collection box, thereby reducing the possibility of debris falling to the bottom of the base with the conveyor belt. It is only necessary to empty the collection box regularly, which is more convenient.

[0031] 4. When the conveyor belt is running, the motor drives the conveyor belt through the cooperation of the active bevel gear and the driven bevel gear, and the conveyor belt drives the brush plate to move.

[0039] The present application is further described in detail below with reference to the accompanying drawings.

[0040] The embodiment of the present application discloses a high-precision aircraft engine blade processing machine tool chip removal mechanism, specifically using its application in a machine tool as an example for description. Figure 1 The machine tool in this embodiment is a five-axis linkage machine tool, which includes a base 1, a bed 2, a workbench 3, a fixture 33 and a tool 4. The base 1 is a rectangular frame structure with a cavity inside. The bottom of the bed 2 is fixedly installed on the bottom wall inside the base 1, the top surface of the bed 2 is horizontal, the bed 2 is located in the center of the base 1, and a gap is left between the bed 2 and the two side walls inside the base 1. The workbench 3 includes a mounting block 31 and a placement table 32. The mounting block 31 is slidably connected to the top surface of the bed 2 along the length direction of the bed 2, and the placement table 32 is slidably connected to the top surface of the mounting block 31 along the width direction of the bed 2. The mounting seat of the fixture 33 is fixedly connected to the top surface of the placement table 32, and the fixture 33 can rotate around the length direction and the width direction of the bed 2 as axes respectively. The mounting seat of the tool 4 is fixedly installed at one end of the top surface of the bed 2, and the tool 4 can slide in the vertical direction. Therefore, the machine tool can realize movement in three directions and rotation in two directions. The workpiece is clamped in the fixture 33, and the machine tool starts to operate to process the required shape of the aviation blade.

[0041] Reference Figure 2The chip removal mechanism includes a linear drive 5, an air supply 6, and an exhaust duct 7. The linear drive 5 is a linear motor 132, fixedly mounted on the base 1 and located above the workbench 3. The length of the linear drive 5 is parallel to the width of the bed 2. The air supply 6 is a blower, fixedly mounted on the base 1. The exhaust duct 7 is located at the output end of the linear drive 5, located above the workbench 3. The air inlet of the exhaust duct 7 is connected to the air outlet of the air supply 6. The air outlet of the exhaust duct 7 faces downward and is slender and rectangular and is arranged along the length of the bed 2. Therefore, the linear drive 5 drives the exhaust duct 7 to move back and forth, blowing air onto the surfaces of the workbench 3 and the bed 2, thereby blowing debris into the base 1 and making the debris cleaning process easier.

[0042] In order to make the wind force in the exhaust duct 7 more concentrated, a plurality of exhaust ducts 7 are provided. Figure 3 and Figure 4 The output end of the linear drive 5 is fixedly connected to a horizontally disposed support rod 8 in a direction perpendicular to the length of the linear drive 5. Multiple connecting blocks 9 are evenly spaced along the length of the support rod 8. The number of connecting blocks 9 is the same as the number of exhaust ducts 7, and each connecting block 9 is connected to only one exhaust duct 7. This ensures that the blown air has a sufficient coverage area while also concentrating the wind force, making it easier to blow debris off the surfaces of the workbench 3 and bed 2. A protective net 72 is installed at the air outlet of the exhaust duct 7 to prevent debris from entering the exhaust duct 7 and causing blockage.

[0043] To further enhance the blowing effect of the exhaust duct 7, the exhaust duct 7 is hinged to the bottom of the connecting block 9. The hinge axis is located on the top side of the exhaust duct 7 and is parallel to the length of the support rod 8. Brackets 91 are welded to the bottom of the connecting block 9 on both the left and right sides of the exhaust duct 7. The two brackets 91 are symmetrically arranged. A first magnet 92 and a second magnet 93 are respectively bonded to the sides of the two brackets 91 that are close to each other. The first magnet 92 and the second magnet 93 are both block-shaped structures, and the angle between the first magnet 92 and the second magnet 93 is a right angle. The magnetic poles of the sides of the first magnet 92 and the second magnet 93 that are close to each other are opposite. A locking magnet 71 is bonded to the top of the exhaust duct 7. When the exhaust duct 7 is rotated to one side, the locking magnet 71 and the first magnet 92 are attracted to each other, securing the exhaust duct 7. When the exhaust duct 7 is rotated to the other side, the locking magnet 71 and the second magnet 93 are attracted to each other, securing the exhaust duct 7. In order to facilitate the switching of the air outlet direction of the exhaust duct 7, a pushing member 11 is provided on the base 1 at both ends of the linear driving member 5 in the length direction. There are multiple pushing members 11 and the number is the same as the exhaust duct 7. Each pushing member 11 corresponds to an exhaust duct 7. The pushing member 11 is a horizontally arranged plate structure, and the pushing member 11 and the corresponding exhaust duct 7 are approximately at the same height.

[0044] In the initial state, the locking magnet 71 is attracted to the first magnet 92, so that the air outlet of the exhaust tube 7 faces the lower left side. The linear drive member 5 drives the exhaust tube 7 to move to the left side through the support rod 8. When the exhaust tube 7 moves to the left side of the base 1, the exhaust tube 7 abuts against the pusher 11 on the base 1. As the support rod 8 moves, the pusher 11 causes the exhaust tube 7 to rotate to the right. When the air outlet of the exhaust tube 7 rotates to the lower right side, the locking magnet 71 is attracted to the second magnet 93, fixing the exhaust tube 7 in this state. Then the linear drive member 5 drives the exhaust tube 7 to move to the right, and this reciprocating cycle is repeated until the debris on the workbench 3 and the bed 2 is blown off. Therefore, the air outlet of the exhaust tube 7 can always be tilted obliquely downward in the direction of movement of the exhaust tube 7, making it easier for the exhaust tube 7 to blow debris to the side away from the exhaust tube 7, thereby blowing the debris off and achieving a better cleaning effect.

[0045] Since the workbench 3 is arranged on the surface of the bed 2, in order to avoid the exhaust duct 7 from colliding with the workbench 3 and the fixture 33 on the workbench 3 when moving, all the exhaust ducts 7 are arranged above the fixture 33. In order to further enhance the chip removal effect of the exhaust duct 7, refer to Figure 2 and Figure 4 , the connecting block 9 is slidably arranged on the support rod 8 in the vertical direction. A vertical T-shaped block 94 is welded on the connecting block 9, and a vertical T-shaped slot 81 is provided on the support rod 8, in which the T-shaped block 94 is clamped; a plurality of first threaded holes are spaced apart along the length direction on the support rod 8, and the axis of the first threaded hole is arranged along the width direction of the bed 2, and each first threaded hole corresponds to a connecting block 9; a plurality of connecting holes 95 are evenly spaced apart along the vertical direction on the connecting block 9, and a locking bolt 96 is passed through the connecting hole 95 coaxial with the first threaded hole, and one end of the locking bolt 96 is threadedly connected to the first threaded hole, thereby fixing the connecting block 9 on the support rod 8. Therefore, the position of each connecting block 9 on the support rod 8 can be adjusted according to the position of the workbench 3 and the clamp 33. The height of the connecting blocks 9 on both sides of the workbench 3 is reduced, thereby reducing the distance between the corresponding exhaust duct 7 and the bed 2, so that the chip removal effect is better.

[0046] After the position of the connecting block 9 is adjusted, the position of the exhaust tube 7 changes, so the original pusher 11 is not at the same height as the exhaust tube 7 after the position change. In order to enable the pusher 11 to push the exhaust tube 7 to rotate and ensure the blowing effect of the exhaust tube 7, the pusher 11 is slidably set on the base 1 in the vertical direction. A vertical connecting seat 10 is fixedly connected to the base 1 by bolts. The connecting seat 10 is provided with multiple and each connecting seat 10 corresponds to a pusher 11. A plurality of second threaded holes 101 are spaced apart in the vertical direction on the connecting seat 10. The spacing between two adjacent second threaded holes 101 is equal to the spacing between two adjacent first threaded holes. A through hole coaxial with the second threaded hole 101 is provided on the pusher 11. A fixing bolt 12 is passed through the through hole. The end of the fixing bolt 12 is threadedly connected to the second threaded hole 101 coaxial with the through hole, thereby fixing the pusher 11 on the connecting seat 10. Therefore, after the position of the connecting block 9 is adjusted, the pushing member 11 is adjusted accordingly so that the pushing member 11 is still at the same height as the exhaust tube 7, and the pushing member 11 can push the exhaust tube 7 to rotate.

[0047] Since the machine tool will continuously spray coolant to cool down during processing, the coolant and the chips fall together. The coolant makes the chips easily adhere to the surface of the workbench 3 or the bed 2 and are not easy to blow off. In order to further enhance the cleaning effect of the chips, refer to Figure 3 A spray pipe 21 is fixedly connected to the side wall of the exhaust duct 7. The spray pipe 21 has a flat body and a rectangular nozzle. The length of the nozzle is parallel to the length of the bed 2. The nozzle of the spray pipe 21 and the air outlet of the exhaust duct 7 face the same direction. Therefore, when cleaning chips after machine tool processing, the exhaust duct 7 blows air downward, while the spray pipe 21 sprays coolant downward, making it easier to wash away the chips.

[0048] The exhaust pipe 7 and the spray pipe 21 can make the debris fall into the base 1 on both sides of the bed 2. In order to facilitate the collection of the debris, refer to Figure 5 Conveyor belts 13 are provided on both sides of the left and right sides of the bed 2 in the base 1. The conveyor belts 13 are used to receive fallen debris and coolant. The length direction of the conveyor belt 13 is parallel to the length direction of the bed 2. A motor 132 for driving the conveyor belt 13 is fixedly installed on the base 1. A collection box 15 is provided at the conveying end of each conveyor belt 13 in the base 1. The collection box 15 is located below the conveyor belt 13, and the opening of the collection box 15 faces upward. Therefore, the motor 132 drives the conveyor belt 13 to operate, and the debris and coolant that fall onto the top surface of the conveyor belt 13 can be discharged into the collection box 15, which is convenient for collecting the debris. A wiping component 17 is provided at the conveying end of the conveyor belt 13, which can wipe the surface of the conveyor belt 13 so that the debris adhering to the surface of the conveyor belt 13 falls into the collection box 15.

[0049] The body of the conveyor belt 13 is made of PVC material, which has a good anti-seepage effect. The coolant is not easy to leak downward through the body of the conveyor belt 13. Protective plates 131 are provided on both sides of the conveyor belt 13. The protective plates 131 can intercept debris and coolant on the top surface of the conveyor belt 13. Guide plates 16 are provided on both sides of the conveyor belt 13 and on the end of the conveyor belt 13 away from the collection box 15. One end of the guide plate 16 is fixedly connected to the frame on which the conveyor belt 13 is located, and the other end of the guide plate 16 abuts the side wall of the base 1 or the bed 2. The guide plate 16 is arranged downwardly from the side away from the conveyor belt 13 to the side close to the conveyor belt 13, so that debris and coolant can fall along the guide plate 16 onto the surface of the conveyor belt 13. In order to further reduce the possibility of debris and coolant falling onto the base 1 at the bottom of the conveyor belt 13, a collection trough 14 is slidably provided on the base 1 at the bottom of the conveyor belt 13. The collection trough 14 is arranged along the length direction of the conveyor belt 13 and the opening is upward. The bottom of the base 1 is provided with an escape opening for the collection trough 14 to slide out; therefore, the collection trough 14 can collect debris and coolant falling from the top, and the collection trough 14 can be pulled out and cleaned regularly.

[0050] Reference Figure 6 The wiping assembly 17 includes a roller 172, a first bristle brush 173, and a first power member 171. The roller 172 is rotatably connected to a frame at one end of the conveyor belt 13 near the collection box 15. The axis of the roller 172 is parallel to the width of the conveyor belt 13. The first bristles 173 are arranged on the outer surface of the roller 172 along the axis of the roller 172. The first bristles 173 are arranged in multiple rows in a circular array. The first bristles 173 on the side closest to the conveyor belt 13 abut the surface of the conveyor belt 13. The first power member 171 includes a rotating shaft 1711, a driving gear 1712, and a driven gear 1713. The rotating shaft 1711 is coaxially fixedly connected to the output shaft of the motor 132, and the pulley at the end of the conveyor belt 13 near the collection box 15 is coaxially fixedly connected to the end of the rotating shaft 1711 away from the motor 132. The driving gear 1712 is coaxially fixedly connected to the rotating shaft 1711, and the driven gear 1713 is coaxially fixedly connected to one end of the roller 172. The driving gear 1712 and the driven gear 1713 are meshed. Therefore, when the motor 132 drives the conveyor belt 13 to operate, the driving gear 1712 and the driven gear 1713 can simultaneously drive the roller 172 to rotate. The rotation direction of the roller 172 is opposite to that of the pulley of the conveyor belt 13, so that the debris adhering to the surface of the conveyor belt 13 can be brushed down to the collection box 15, thereby enhancing the chip removal effect and making the device more energy-efficient.

[0051] In order to make the coolant falling into the collection box 15 recyclable, refer to Figure 5The bottoms of the two collection boxes 15 are connected by a connecting pipe 151. A filter 152 is installed at the opening of the collection boxes 15. A pump body 18 is installed at the bottom of one of the collection boxes 15 within the base 1. The liquid inlet of the pump body 18 is connected to the interior of the collection box 15 through the side wall of the bottom of the collection box 15. The liquid outlet of the pump body 18 is connected to a pipe 22. The end of the pipe 22 away from the pump body 18 is connected to a first delivery pipe 221. A first valve body 2211 is installed on the first delivery pipe 221. The end of the first delivery pipe 221 away from the pipe 22 extends into a tank for storing coolant. During processing, the first valve body 2211 is opened, and the sprayed coolant can be filtered and reused, thereby reducing usage costs. The end of the pipeline 22 away from the pump body 18 is also connected to a second delivery pipe 222, and a second valve body 2221 is installed on the second delivery pipe 222. The end of the second valve body 2221 away from the pipeline 22 is connected to multiple hoses 23, and each hose 23 is connected to a spray pipe 21. Therefore, after the machine tool processing is completed, the first valve body 2211 is closed and the second valve body 2221 is opened, and the spray pipe 21 can spray, thereby enhancing the chip removal effect and making more full use of the coolant.

[0052] The two collecting boxes 15 are arranged at intervals, and a chip box 19 is provided between the two collecting boxes 15. The openings of the chip box 19 and the collecting box 15 are flush. A cleaning component 20 is provided on the top of the filter 152. The cleaning component 20 can clean the debris accumulated on the surface of the filter 152 into the chip box 19, thereby ensuring the unobstructed flow of the filter 152.

[0053] Reference Figure 6The cleaning assembly 20 includes a conveyor belt 202, a brush plate 203, and a second power member 201. The conveyor belt 202 is arranged on the side of the roller 172 away from the conveyor belt 13. The conveyor belt 202 is arranged along the width direction of the conveyor belt 13. One end of the conveyor belt 202 is located above the filter screen 152, and the other end of the conveyor belt 202 is located above the chip box 19. A plurality of brush plates 203 are provided, and are arranged on the outer surface of the conveyor belt 202 at intervals along the length direction of the conveyor belt 202. The length direction of the brush plates 203 is parallel to the width direction of the conveyor belt 202. A second bristle 2031 is provided on the side of the brush plate 203 away from the belt surface of the conveyor belt 202. The second bristles 2031 on the brush plate 203 at the bottom of the conveyor belt 202 abut against the surface of the filter screen 152. The second power member 201 includes a driving bevel gear 2011, a driven bevel gear 2012 and a connecting shaft 2013. The driving bevel gear 2011 is coaxially fixedly connected to the rotating shaft 1711, and the driven bevel gear 2012 is rotatably set on the base 1. The driven bevel gear 2012 is coaxially fixedly connected to one end of the connecting shaft 2013, and the other end of the connecting shaft 2013 is coaxially fixedly connected to one of the pulleys of the conveyor belt 202. The driving bevel gear 2011 and the driven bevel gear 2012 are meshed. Therefore, when the motor 132 drives the conveyor belt 13 to operate, the conveyor belt 202 can be driven to operate through the cooperation of the active bevel gear 2011 and the driven bevel gear 2012, and the conveyor belt 202 drives the brush plate 203 to move. When the brush plate 203 at the bottom of the conveyor belt 202 moves, the debris falling on the surface of the filter screen 152 can be brushed into the chip collecting box 19, thereby reducing the debris accumulated on the surface of the filter screen 152, so that the filter screen 152 can remain unobstructed, thereby ensuring the screening efficiency and allowing the coolant to circulate better.

[0054] The implementation principle of the chip removal mechanism of a high-precision aircraft engine blade processing machine tool in the embodiment of the present application is as follows: during machine processing, the motor 132 is started, and the motor 132 drives the conveyor belt 13 to operate. The debris and coolant falling on the surface of the conveyor belt 13 can be transported to the opening of the collection box 15 by the conveyor belt 13, and the debris falls on the filter 152, and the coolant enters the collection box 15; while the motor 132 drives the conveyor belt 13 to operate, the driving gear 1712 and the driven gear 1713 cooperate to drive the roller 172 to rotate, and the first bristles 173 on the roller 172 will adhere to the debris brush on the surface of the conveyor belt 13. To the filter screen 152 on the open side of the collection box 15; at the same time, the motor 132 drives the conveyor belt 202 to operate through the cooperation of the active bevel gear 2011 and the driven bevel gear 2012, and the conveyor belt 202 drives the brush plate 203 to move, and the second bristles 2031 on the brush plate 203 at the bottom of the conveyor belt 202 brush the debris that falls on the filter screen 152 into the chip collection box 19; during the machine tool processing, the first valve body 2211 is opened, the second valve body 2221 is closed, and the pump body 18 is opened, and the pump body 18 draws the coolant filtered by the filter screen 152 into the box for placing the coolant, so that the coolant can be recycled.

[0055] After the machine tool processing is completed, the first valve body 2211 is closed, the second valve body 2221 is opened, and the pump body 18 is opened. The pump body 18 draws the coolant in the collection box 15 into the spray pipe 21, and then sprays it out through the spray pipe 21; in the initial state, the locking magnet 71 and the first magnet 92 on the exhaust tube 7 are attracted to each other, and the air outlet of the exhaust tube 7 is facing the lower left. The linear drive member 5 drives the exhaust tube 7 to move through the support rod 8. The exhaust tube 7 blows air downward while moving, and the spray pipe 21 sprays downward, so that the debris on the surface of the workbench 3 and the bed 2 can be cleaned to the conveyor belts 13 on both sides of the bed 2 , the conveyor belt 13 then transports the debris to the filter 152 on the top of the collection box 15, and the brush plate 203 on the conveyor belt 202 brushes the debris into the chip collection box 19; when the exhaust cylinder 7 moves to the left side of the base 1, the exhaust cylinder 7 abuts against the pusher 11, and as the support rod 8 moves, the exhaust cylinder 7 rotates to the right until the locking magnet 71 and the second magnet 93 on the exhaust cylinder 7 are attracted. At this time, the air outlet of the exhaust cylinder 7 faces the lower right, and then the linear drive part 5 drives the exhaust cylinder 7 to move to the right again for chip removal and cleaning, and this cycle is repeated until the debris on the workbench 3 and the bed 2 are cleared.

[0056] The above are optional embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
