Description

Technical Field

[0001] This invention relates to the field of CNC machining centers, and more particularly to a CNC machining center for rotor machining and its control system. Background Technology

[0002] Machining centers evolved from CNC milling machines. The biggest difference between them and CNC milling machines is that machining centers have the ability to automatically change machining tools. By installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed in a single setup via an automatic tool changer, thus achieving multiple machining functions.

[0003] In existing CNC machining centers for rotor machining, a large amount of debris is generated during the machining process, and a large amount of cutting fluid may also be sprayed during the machining process. In existing technology, slag discharge troughs are usually set on both sides of the machining table to collect debris and cutting fluid. However, during the collection process, debris is very likely to block the slag discharge troughs, making it difficult for the cutting fluid to be discharged and causing it to overflow the surface of the machining table. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a CNC machining center for rotor machining and its control system.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a CNC machining center for rotor machining, comprising a housing, wherein a machining table is provided within the housing, and further comprising: Two inclined grooves are symmetrically arranged on both sides of the processing table, and the bottom of the inclined grooves is inclined. A pushing assembly, each of which is disposed inside the inclined groove, is used to push debris in the inclined groove toward the end of the inclined groove; A collection component for collecting debris at the end of the chute; The processing terminal is used to control the pushing component to make close contact with the bottom of the inclined groove during the pushing process, and to disengage the pushing component from the bottom of the groove during the resetting process. Specifically, existing CNC machining centers generate a large amount of debris when machining workpieces, and may also spray a large amount of cutting fluid during the machining process. In existing technology, slag discharge troughs are usually set on both sides of the machining table to collect debris and cutting fluid. However, during the collection process, debris is very likely to clog the slag discharge troughs, making it difficult for the cutting fluid to be discharged and causing it to overflow the surface of the machining table. The present invention sets up inclined grooves, and blows debris into the interior of the inclined grooves on both sides by existing wind blowing or other means, so that the debris can slide along the inclined surface of the groove into the collection component, and the cutting fluid can also flow with the inclined surface. However, some of the chips have a certain amount of heat after cutting. After falling into the inclined chute, they may stick together. By setting up a pushing component to push them in the inclined chute, the sticky chips can be removed from the inclined chute, making it easier to collect the chips. Furthermore, if the component is pushed back directly during the reset process, the impurities will be pushed away from the end of the collection component. Therefore, the present invention controls the bottom of the pushing component to detach from the bottom of the tank during reset, thereby avoiding the situation where the impurities are pushed in the opposite direction.

[0006] Preferably, the actuating component includes: A screw, which is rotatably connected inside an inclined slot, and a motor is fixed to one end of the screw; A push plate is inserted into an inclined groove. The push plate has a fixed part and a movable part. The fixed part is threadedly connected to a screw. The movable part is vertically slidably sleeved on the outside of the fixed part. A first spring is provided between the push plate and the fixed part. An electric cylinder, wherein the movable end of the electric cylinder is connected to a movable part via a connector; The motor can be started to drive the screw to rotate, thereby moving the push plate in the inclined groove. Through the cooperation of the moving part and the fixed part, the push plate can be contracted and extended to meet the height changes at different positions in the inclined groove. Furthermore, during reset, by activating the electric cylinder, the movable part can be pulled upward through the connecting piece, thereby causing the bottom of the push plate to detach from the bottom surface of the inclined groove.

[0007] Preferably, the connector includes: A sleeve is fixed to the inner wall of the movable part, and the movable end of the electric cylinder is slidably inserted into the sleeve. A pull plate, which is fixed to the bottom of the movable end of the electric cylinder; During the start-up of the electric cylinder, when the electric cylinder retracts, it can adjust the pull plate to move upward, so that the pull plate contacts the top of the inner wall of the sleeve, pulling the sleeve and the moving part upward as a whole, so that the bottom of the moving part separates from the bottom surface of the inclined groove, providing space for impurities to pass through.

[0008] Preferred options also include: The permeable trough is formed on the top surface of the fixed part; A liquid level sensor is installed inside the permeable tank and is used to detect the liquid level information in the permeable tank. The liquid level sensor is used to detect the liquid level inside the permeable tank. When the liquid level inside the permeable tank is high, it means that the liquid level at the end of the push plate away from the collection component is too high and will be submerged from the top of the push plate. In this case, in order to ensure the smooth discharge of the cutting fluid, the movable part needs to be adjusted to rise so that the cutting fluid can be discharged from the bottom of the movable part.

[0009] Preferred options also include: A slide groove is formed on the bottom surface of the movable part; A filter screen is vertically slidably connected inside a slide groove, and a second spring is provided between the filter screen and the slide groove. In this invention, when there is too much cutting fluid and the movable part needs to be adjusted to rise, a filter screen is installed at the bottom of the movable part to prevent impurities from entering the bottom of the movable part. When the movable part rises, the filter screen can move downward under the push of the second spring, thereby blocking impurities from entering the bottom of the movable part and ensuring that the movable part will not be stuck when it descends.

[0010] Preferred options also include: A guide bar is fixed to the inner wall of the slide groove, and a guide surface is provided at the bottom of the guide bar; A telescopic plate, which is fixed to the top of the filter screen, and the top of the movable end of the telescopic plate is fixed to a second spring; The design incorporates a telescopic plate. When the movable part descends, it causes the guide strip to descend synchronously. Guided by the guide surface, the filter screen moves away from the guide strip and compresses the telescopic plate. This causes the telescopic plate to retract and make room, ensuring that the side of the filter screen that blocks impurities does not contact the inner wall of the chute during its ascent. This prevents impurities from getting stuck on the filter screen and causing it to jam under the push of the inner wall of the chute during its ascent.

[0011] Preferably, the collection component includes: A collection box is fixed to the outer wall of the shell and is located at one end of the inclined groove. A drain pipe is fixedly connected to the side wall of the collection box. A filter plate is fixed to the inner wall of the collection box and is positioned above the drain pipe. In this process, the debris flows into the collection box along the inclined channel and is blocked by the filter plate, while the cutting fluid can be discharged from the drain pipe through the filter plate, thus ensuring the separation of dry and wet materials in the collection box and facilitating the separate treatment of debris and cutting fluid.

[0012] Secondly, the present invention provides a control system for a CNC machining center for rotor machining, the control method comprising the following steps: The liquid level information is obtained, which is generated by the liquid level sensor detecting the liquid level height in the permeable tank; The liquid level information is compared with the preset liquid level height information. When the liquid level information is greater than the preset liquid level height information, the liquid level abnormality information is determined. Based on the abnormal liquid level information, the electric cylinder is controlled to retract, causing the moving part to detach from the bottom surface of the inclined trough.

[0013] Preferably, the specific method of using the liquid level sensor includes the following steps: Obtain the liquid level height in the permeable tank; Liquid level information is generated based on the liquid level height in the permeable tank; The liquid level information is sent to the processing terminal.

[0014] Compared with the prior art, the present invention has the following beneficial effects: I. This invention, by setting up inclined grooves, blows debris into the inclined grooves on both sides using existing wind or other methods, allowing the debris to slide along the inclined surface of the grooves into the collection component, and the cutting fluid can also flow along the inclined surface. However, some debris has a certain amount of heat after cutting, and may stick after falling into the inclined grooves. By setting up a pushing component, the sticky debris can be pushed out of the inclined grooves, thus facilitating the collection of debris.

[0015] Second, if the component is pushed back directly during the reset process, the impurities will be pushed away from the end of the collection component. Therefore, this invention controls the bottom of the pushing component to detach from the bottom of the tank during reset, thereby avoiding the situation where the impurities are pushed in the opposite direction.

[0024] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0025] like Figures 1 to 6 The CNC machining center for rotor machining shown includes a housing 1, a machining table 2 inside the housing 1, and further includes: Two inclined grooves 3 are symmetrically opened on both sides of the processing table 2, and the bottom of the inclined grooves 3 is inclined. Each pusher assembly is disposed inside the inclined groove 3 and is used to push the debris in the inclined groove 3 toward the end of the inclined groove 3; The collection component is used to collect debris from the end of the inclined chute 3; Processing terminal 24 is used to control the pushing component to make close contact with the bottom of the inclined groove 3 during the pushing process, and to disengage the pushing component from the bottom of the groove during the reset process; Specifically, existing CNC machining centers generate a large amount of debris when machining workpieces, and may also spray a large amount of cutting fluid during the machining process. In existing technology, slag discharge grooves are usually set on both sides of the machining table 2 to collect debris and cutting fluid. However, during the collection process, debris is very likely to clog the slag discharge grooves, making it difficult for the cutting fluid to be discharged and causing it to overflow the surface of the machining table 2. The present invention provides a sloping groove 3, which blows debris into the sloping groove 3 on both sides by existing wind or other means, so that the debris can slide along the slope of the sloping groove 3 into the collection assembly, and the cutting fluid can also flow with the slope. However, some of the debris has a certain amount of heat after cutting. After falling into the inclined groove 3, it may stick together. By setting up a pushing component to push it in the inclined groove 3, the sticky debris can be removed from the inclined groove 3, which makes it easier to collect the debris. Furthermore, if the component is pushed back directly during the reset process, the impurities will be pushed away from the end of the collection component. Therefore, the present invention controls the bottom of the pushing component to detach from the bottom of the tank during reset, thereby avoiding the situation where the impurities are pushed in the opposite direction.

[0026] As a further embodiment of the present invention, the driving component includes: Screw 4 is rotatably connected inside the inclined groove 3, and a motor 5 is fixed to one end of screw 4; Push plate 6 is inserted inside inclined groove 3. Push plate 6 has fixed part 7 and movable part 8. Fixed part 7 is threadedly connected to screw 4. Movable part 8 is vertically slidably sleeved on the outside of fixed part 7. First spring 9 is provided between push plate 6 and fixed part 7. Electric cylinder 10, the movable end of electric cylinder 10 is connected to movable part 8 via a connector; Among them, by starting the motor 5, the screw 4 can be driven to rotate, thereby causing the push plate 6 to move in the inclined groove 3. Through the cooperation of the movable part 8 and the fixed part 7, the push plate 6 can be contracted and extended, thereby satisfying the height change of different positions in the inclined groove 3. Furthermore, during reset, by activating the electric cylinder 10, the movable part 8 can be pulled upward through the connecting piece, thereby causing the bottom of the push plate 6 to detach from the bottom surface of the inclined groove 3.

[0027] As a further embodiment of the present invention, the connector includes: Sleeve 11 is fixed on the inner wall of movable part 8, and the movable end of electric cylinder 10 is slidably inserted into sleeve 11. Pull plate 12, which is fixed to the bottom of the movable end of electric cylinder 10; During the start-up of the electric cylinder 10, when the electric cylinder 10 retracts, it can adjust the pull plate 12 to move upward, so that the pull plate 12 contacts the top of the inner wall of the sleeve 11, pulling the sleeve 11 and the movable part 8 to move upward as a whole, so that the bottom of the movable part 8 separates from the bottom surface of the inclined groove 3, providing clearance space for impurities to pass through.

[0028] As a further embodiment of the present invention, it also includes: Water permeable channel 13 is formed on the top surface of the fixing part 7; Liquid level sensor 14 is installed inside the permeable tank 13 and is used to detect the liquid level information in the permeable tank 13. The liquid level sensor 14 is used to detect the liquid level inside the permeable tank 13. When the liquid level inside the permeable tank 13 is high, it means that the liquid level at the end of the push plate 6 away from the collection component is too high and will be submerged from the top of the push plate 6. At this time, in order to ensure the smooth discharge of the cutting fluid, the movable part 8 needs to be adjusted to rise so that the cutting fluid can be discharged from the bottom of the movable part 8.

[0029] As a further embodiment of the present invention, it also includes: Slide 15, slide 15 is formed on the bottom surface of movable part 8; A filter screen 16 is vertically slidably connected inside a slide groove 15, and a second spring 17 is provided between the filter screen 16 and the slide groove 15. In this invention, when there is too much cutting fluid and the movable part 8 needs to be adjusted to rise, in order to prevent impurities from entering the bottom of the movable part 8, a filter screen 16 is provided at the bottom of the movable part 8. When the movable part 8 rises, the filter screen 16 can move downward under the push of the second spring 17, thereby blocking impurities from entering the bottom of the movable part 8 and ensuring that the movable part 8 will not be stuck when it descends.

[0030] As a further embodiment of the present invention, it also includes: Guide bar 18 is fixed on the inner wall of slide groove 15, and guide surface 19 is provided at the bottom of guide bar 18; Telescopic plate 20 is fixed to the top of filter screen 16, and the top of the movable end of telescopic plate 20 is fixed to the second spring 17. In this design, by setting the telescopic plate 20, when the movable part 8 descends, it will drive the guide bar 18 to descend synchronously. Under the guidance of the guide surface 19, the filter screen 16 can be pushed to the side away from the guide bar 18 and compress the telescopic plate 20. This causes the telescopic plate 20 to retract and make room, so that the side of the filter screen 16 that blocks impurities does not contact the inner wall of the slide 15 during the upward process. This prevents impurities from getting stuck on the filter screen 16 and avoids jamming caused by the push of the inner wall of the slide 15 during the upward process of the filter screen 16.

[0031] As a further embodiment of the present invention, the collecting components include: Collection box 21 is fixed on the outer wall of housing 1. Collection box 21 is set at one end of inclined groove 3. Drainage pipe 22 is fixedly connected to the side wall of collection box 21. Filter plate 23 is fixed on the inner wall of collection box 21 and is positioned above drain pipe 22. In this process, the debris flows into the collection box 21 along the inclined groove 3 and is blocked by the filter plate 23, while the cutting fluid can be discharged from the drain pipe 22 through the filter plate 23, thereby ensuring the separation of dry and wet materials in the collection box 21 and facilitating the separate processing of debris and cutting fluid.

[0032] like Figure 7 The control system of a CNC machining center for rotor machining shown includes the following steps: The liquid level information is obtained by the liquid level sensor 14 detecting the liquid level height of the permeable tank 13; The liquid level information is compared with the preset liquid level height information. When the liquid level information is greater than the preset liquid level height information, the liquid level abnormality information is determined. Based on the abnormal liquid level information, the electric cylinder 10 is controlled to retract, causing the movable part 8 to detach from the bottom surface of the inclined trough 3.

[0033] As a further embodiment of the present invention, the specific method of using the liquid level sensor 14 includes the following steps: Obtain the liquid level height of the permeable tank 13; Liquid level information is generated based on the liquid level height in the permeable tank 13; The liquid level information is sent to the processing terminal 24.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
