[0001] The invention relates to the field of numerical control machining centers, and in particular to a CNC numerical control machining center for rotor machining and a control system thereof. Background Art
[0002] The machining center is developed from the CNC milling machine. The biggest difference between the machining center and the CNC milling machine is that the machining center has the ability to automatically exchange machining tools. By installing tools of different purposes on the tool magazine, the machining tools on the spindle can be changed through the automatic tool changer in one clamping, realizing multiple machining functions.
[0003] The CNC machining center for rotor machining in the prior art will generate a large amount of debris when machining the workpiece, and a large amount of cutting fluid may also be sprayed during the machining process. In the prior art, slag discharge grooves are mostly set on both sides of the machining table to collect the debris and cutting fluid. However, during the collection process, the debris is very likely to block the slag discharge groove, resulting in difficulty in discharging the cutting fluid and flooding the surface of the machining table. Summary of the invention
[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a CNC machining center for rotor machining and a control system thereof.
[0005] To achieve the above objectives, in a first aspect, the present invention provides a CNC machining center for machining a rotor, comprising a housing, a machining table being arranged in the housing, and further comprising: Two inclined grooves, the two inclined grooves are symmetrically arranged on both sides of the processing table, and the groove bottoms of the inclined grooves are in an inclined state; A pushing assembly, each of which is arranged inside the chute, and is used to push the debris in the chute toward the end of the chute; A collecting assembly, the collecting assembly is used to collect debris at the end of the chute; A processing terminal, the processing terminal is used to control the pushing component to be in close contact with the bottom of the chute during the pushing process, and to push the component away from the bottom of the chute during the resetting process; Specifically, in the prior art, a CNC machining center will generate a large amount of debris when machining a workpiece, and a large amount of cutting fluid may also be sprayed during the machining process. In the prior art, slag discharge grooves are usually set on both sides of the machining table to collect the debris and cutting fluid. However, during the collection process, the debris is very likely to block the slag discharge groove, making it difficult for the cutting fluid to be discharged, and the cutting fluid may not cover the surface of the machining table. The present invention provides an inclined groove, and blows the debris to the inside of the inclined grooves on both sides by existing wind blowing or other methods, so that the debris can slide along the inclined surface of the inclined groove to the collection component, and the cutting fluid can also flow along the inclined surface; However, some chips have a certain amount of heat after cutting, and may get stuck after falling into the chute. By setting a pushing component to push the chips in the chute, the stuck chips can be separated from the chute, so that the chips can be collected easily. Furthermore, during the process of resetting the pushing component, if it retreats directly, the impurities will be pushed to the end away from the collecting component. Therefore, when resetting, the present invention controls the bottom of the pushing component to separate from the bottom of the groove, thereby avoiding the impurities being pushed in the opposite direction.
[0006] Preferably, the pushing assembly comprises: A screw rod, the screw rod is rotatably connected to the inside of the chute, and a motor is fixed to one end of the screw rod; A push plate, the push plate is inserted into the inclined groove, the push plate has a fixed part and a movable part, the fixed part is threadedly connected to the screw, the movable part is vertically slidably sleeved on the outer side of the fixed part, and a first spring is arranged between the push plate and the fixed part; An electric cylinder, wherein the movable end of the electric cylinder is connected to the movable part through a connecting piece; Among them, by starting the motor, the screw rod can be driven to rotate, so that the push plate can move in the inclined slot, and the push plate can be contracted and extended by the cooperation of the movable part and the fixed part, so as to meet the height changes of different positions in the inclined slot; And when resetting, by starting the electric cylinder, the movable part can be pulled upward through the connecting piece, so that the bottom of the pushing plate is separated from the bottom surface of the inclined groove.
[0007] Preferably, the connecting member comprises: A sleeve, wherein the sleeve is fixed on the inner wall of the movable part, and the movable end of the electric cylinder is slidably inserted in the sleeve; A pulling plate, the pulling plate being fixed to the bottom of the movable end of the electric cylinder; Among them, in the process of starting the electric cylinder, when the electric cylinder contracts, the pulling plate can be adjusted to move upward, so that the pulling plate contacts the top of the inner wall of the sleeve, and the sleeve and the movable part are pulled upward as a whole, so that the bottom of the movable part is separated from the bottom surface of the inclined groove, providing space for impurities to pass through.
[0008] Preferably, it also includes: A water-permeable groove, the water-permeable groove is arranged on the top surface of the fixing part; A liquid level sensor, the liquid level sensor is arranged inside the water permeable tank, and the liquid level sensor is used to detect the liquid level information in the water permeable tank; Among them, a liquid level sensor is set to detect the liquid level inside the water permeable groove. When the liquid level in the water permeable groove is high, it means that the liquid level at the end of the push plate away from the collecting component is too high and will submerge the top of the push plate. At this time, in order to ensure the smooth discharge of the cutting fluid, it is necessary to adjust the movable part to rise so that the cutting fluid can be discharged from the bottom of the movable part.
[0009] Preferably, it also includes: A chute, the chute being provided on the bottom surface of the movable part; A filter screen, the filter screen is vertically slidably connected inside the slide slot, and a second spring is arranged between the filter screen and the slide slot; Among them, when there is too much cutting fluid and the movable part needs to be adjusted to rise, in order to prevent impurities from entering the bottom of the movable part, the present invention arranges a filter net at the bottom of the movable part. When the movable part rises, the filter net can move downward under the push of the second spring, thereby blocking impurities from entering the bottom of the movable part, ensuring that the movable part will not be stuck when it descends subsequently.
[0010] Preferably, it also includes: A guide bar, the guide bar is fixed on the inner wall of the slide groove, and a guide surface is provided at the bottom of the guide bar; A telescopic plate, the telescopic plate is fixed on the top of the filter screen, and the top of the movable end of the telescopic plate is fixed to the second spring; Among them, by setting a telescopic plate, when the movable part descends, it will drive the guide bar to descend synchronously. Under the guidance of the guide surface, the filter net can be pushed to the side away from the guide bar and compress the telescopic plate, so that the telescopic plate shrinks and makes way, so that the side of the filter net that blocks impurities does not contact the inner wall of the slide groove during the rising process, thereby avoiding impurities from being stuck on the filter net. During the rising process of the filter net, it is pushed by the inner wall of the slide groove and becomes stuck.
[0011] Preferably, the collecting assembly comprises: A collecting box, the collecting box is fixed on the outer wall of the shell, the collecting box is arranged at one end of the chute, and a drainage pipe is fixedly connected to the side wall of the collecting box; A filter plate, the filter plate is fixed on the inner wall of the collection box, and the filter plate is arranged above the drain pipe; Among them, after the debris flows into the collection box along the chute, it is blocked by the filter plate, while the cutting fluid can be discharged from the drain pipe through the filter plate, thereby ensuring the separation of dry and wet in the collection box, making it easy to handle the debris and cutting fluid separately.
[0012] In a second aspect, the present invention provides a control system for a CNC machining center for rotor machining, the control method comprising the following steps: Acquiring liquid level value information, wherein the liquid level value information is generated by detecting the liquid level height of the water permeable tank by a liquid level sensor; Compare the liquid level value information with the preset liquid level height value information, and when the liquid level value information is greater than the preset liquid level height value, determine the liquid level abnormality information; The electric cylinder is controlled to retract according to abnormal liquid level information, so that the movable part is separated from the bottom surface of the chute.
[0013] Preferably, the specific method of using the liquid level sensor includes the following steps: Get the liquid level of the water permeable tank; Generate liquid level value information according to the liquid level height of the water permeable tank; Send the liquid level value information to the processing terminal.
[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides an inclined groove, and uses existing wind blowing or other methods to blow the debris into the inside of the inclined grooves on both sides, so that the debris can slide along the inclined surface of the inclined groove to 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 after falling into the inside of the inclined groove, it may get stuck. By providing a pushing component to push in the inclined groove, the stuck debris can be separated from the inclined groove, thereby facilitating the collection of the debris.
[0015] Second, during the process of resetting the pushing component, if it retreats directly, the impurities will be pushed to the end away from the collecting component. Therefore, during resetting, the present invention controls the bottom of the pushing component to separate from the bottom of the groove, thereby preventing the impurities from being pushed in the reverse direction.

In the prior art, slag discharge grooves are usually set on both sides of the machining table 2 to collect the debris and cutting fluid. However, during the collection process, the debris is very likely to block the slag discharge groove, making it difficult for the cutting fluid to be discharged, and the cutting fluid may not cover the surface of the machining table 2. The present invention provides the inclined groove 3, and blows the debris to the inside of the inclined groove 3 on both sides by existing wind blowing or other methods, so that the debris can slide along the inclined surface of the inclined groove 3 to the collection component, and the cutting fluid can also flow along the inclined surface; However, some chips have a certain amount of heat after cutting, and may get stuck after falling into the chute 3. By setting a pushing component to push in the chute 3, the stuck chips can be separated from the chute 3, so that the chips can be collected easily. Furthermore, during the process of resetting the pushing component, if it retreats directly, the impurities will be pushed to the end away from the collecting component. Therefore, when resetting, the present invention controls the bottom of the pushing component to separate from the bottom of the groove, thereby avoiding the impurities being pushed in the opposite direction.

An electric cylinder 10, wherein the movable end of the electric cylinder 10 is connected to the movable part 8 via a connecting piece; By starting the motor 5, the screw rod 4 can be driven to rotate, so that the push plate 6 moves in the chute 3. Through the cooperation of the movable part 8 and the fixed part 7, the push plate 6 can be contracted and extended, so as to meet the height changes of different positions in the chute 3. When resetting, by starting the electric cylinder 10 , the movable part 8 can be pulled upward through the connecting piece, so that the bottom of the push plate 6 is separated from the bottom surface of the inclined groove 3 .
