Description

Technical Field

[0001] The present invention relates to the technical field of CNC milling machines, and particularly to a CNC milling machine with a metal chip collection structure. Background Art

[0002] As a common part production equipment, a CNC milling machine will generate a large amount of metal chips carrying oil stains during the working process. If these chips cannot be processed in time, once they adhere to the parts in production in large quantities, it will greatly affect the accuracy of the parts. For example, in the processing of some precision parts, even the attachment of tiny chips may cause dimensional deviation or surface quality problems. After the existing CNC milling machines finish processing, they cannot automatically clean the waste chips generated during processing, and often require manual cleaning, which undoubtedly increases the labor intensity of workers and reduces work efficiency. Moreover, if the chips accumulate on the equipment and are not cleaned in time, it will also affect production safety and production efficiency. In addition, the metal part chips cannot be recycled in time, resulting in waste of resources.

[0003] Currently, conventional CNC milling machines lack corresponding devices for compressing metal chips. The metal chips occupy a large volume and are loose, which is not conducive to recycling. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A CNC milling machine with a metal chip collection structure. It includes a support base plate, on the top of which a cutting support is fixedly connected. On the side of the cutting support, a milling device is fixedly connected. On the top of the support base plate, a fixing device is fixedly connected. On the top of the support base plate, a metal collection device is fixedly connected. The milling device is arranged above the fixing device, and the metal collection device is arranged at the bottom of the fixing device;

[0005] The fixing device includes a fixing frame, on the top of which an arc-shaped baffle is fixedly connected. On the side of the inner wall of the fixing frame, a bidirectional moving device is fixedly connected. On the top of the bidirectional moving device, a rotating table is fixedly connected. On the top of the rotating table, a fixing component is fixedly connected. The bottom of the fixing frame is fixedly connected to the top of the support base plate. The fixing component is arranged below the milling device. The rotating table drives the fixing component to rotate to drive the workpiece to be adjusted at different angles. The bidirectional moving device adjusts the position of the workpiece to cope with different machining positions. The arc-shaped baffle is arranged on the top of the fixing frame. Through the arc design, the flying chips are reflected and bounced back, and the chips are reflected back into the interior of the fixing frame, thereby reducing the possibility of chips flying out, which is conducive to the collection of metal chips.

[0006] Preferably, the fixing component includes a fixing base plate. A clamping plate is slidably connected to the top of the fixing base plate through a chute. A screw rod penetrates and is threadedly connected to the side surface of the fixing base plate. One end of the screw rod is sleeved and fixedly connected with a conductive slip ring. The screw rod penetrates the side surface of the fixing base plate and is rotatably connected to the fixing base plate. A braking component is sleeved and fixedly connected to a part of the side surface of the screw rod on one side of the conductive slip ring. A first motor is fixedly connected to the center position of the side surface of the fixing base plate. A driving shaft of the first motor is fixedly connected with a sprocket transmission mechanism. The driving shaft of the first motor is fixedly connected to the input end of the braking component through the sprocket transmission mechanism. The bottom of the fixing base plate is fixedly connected to the top of the rotating table.

[0007] Preferably, the braking component includes a driving sprocket. A braking slot is formed in the side surface of the driving sprocket. A braking strip is rotatably connected to the inner wall of the braking slot through a rotating pin. An electromagnet column penetrates and is fixedly connected to the side surface of the driving sprocket. The electromagnet column extends into the interior of the braking slot. A torsion spring is fixedly connected to the side surface of the braking strip. One end of the torsion spring away from the braking strip is fixedly connected to the driving sprocket.

[0008] Preferably, the driving sprocket is sleeved on the side surface of the screw rod and fixedly connected to the screw rod. The driving sprocket is arranged on the side surface of the conductive slip ring. A slot adapted to the braking strip is formed in the side surface of the fixing base plate. The screw rotates to drive the clamping plate to approach or move away from the side surface of the fixing base plate through the thread. The workpiece is placed on the top of the fixing base plate, so that the clamping plate drives the workpiece to approach the side surface of the fixing base plate to clamp the workpiece. Lifting blocks are arranged on the side surfaces of the fixing base plate and the clamping plate, so that the clamping force is concentrated on the surface of the workpiece, which is more conducive to clamping the workpiece. The conductive slip ring connects the current of the first motor to the electromagnet column, so that the electromagnet column has a magnetic attraction effect while the screw rod rotates. The electromagnet column has an attraction effect to drive the braking strip to rotate, so that the braking strip is retracted into the interior of the driving sprocket. The braking strip rotates to compress the torsion spring, so that the torsion spring generates torsion. At this time, the driving sprocket rotates. When the first motor stops running, the electromagnet column loses the attraction force on the braking strip, so that the braking strip automatically rotates back to the position extending out of the driving sprocket under the torsion of the torsion spring, so that the end of the braking strip is caught in the slot formed in the side surface of the fixing base plate. One end of the braking strip abuts against the slot formed in the side surface of the fixing base plate, and the other end abuts against the side surface of the driving sprocket, so as to brake the driving sprocket, so as to maintain the clamping state after the workpiece is clamped. Compared with the traditional methods of using thread braking or using a motor to automatically clamp and using the motor to brake, this direct braking method can bear a larger load, so as to avoid the workpiece clamping failure caused by braking failure and prevent loosening during cutting.

[0009] Preferably, the metal collection device includes a material guiding pipe, a drying device is fixedly connected to the side of the material guiding pipe, a compression device is communicated with the bottom of the material guiding pipe, a coolant filter screen is fixedly connected to the bottom of the material guiding pipe, and the top of the material guiding pipe is communicated with the bottom of the fixed frame.

[0010] Preferably, the metal collection device further includes a filtering device, the filtering device is arranged at the bottom of the coolant filter screen, and the bottom of the coolant filter screen is fixedly connected to the top of the support bottom plate.

[0011] Preferably, the drying device includes an air inlet frame, an electric heating wire is fixedly connected to the inner wall of the air inlet frame, an air inlet fan penetrates and is fixedly connected to the side of the air inlet frame, an air inlet grille is communicated with the side of the air inlet frame, and a guiding plate is fixedly connected to the side of the air inlet grille.

[0012] Preferably, the air inlet grille is fixedly connected to the inner side surface of the material guiding pipe, the side of the air inlet frame is fixedly connected to the side of the material guiding pipe. The air inlet fan rotates to drive air to pass by the side of the electric heating wire and enter the interior of the air inlet grille under the driving action of the air inlet fan and reach the interior of the material guiding pipe through the guiding plate, so as to dry the metal chips, thereby separating the metal chips and the coolant. The metal chips fall in the material guiding pipe, and the metal chips and the coolant are separated under the action of the coolant filter screen. And through the filtering action of the filtering device, the fine metal chips and the coolant are filtered and separated. The air inlet grille and the guiding plate are at a certain angle inside the material guiding pipe, and the chips fall on the upper surfaces of the air inlet grille and the guiding plate, so as to extend the residence time of the chips inside the material guiding pipe, so as to better separate the coolant and the metal chips. Thus, the filtering of the metal chips and the separation of the coolant are realized, which is beneficial to the collection of the metal chips, and the coolant can be reused after being filtered.

[0013] Preferably, the compression device includes a fixed frame, a second motor is fixedly connected to the side of the fixed frame, a debris conduit is fixedly connected to the side of the fixed frame, a spiral compression plate is fixedly connected to the drive shaft of the second motor, a pipe support is fixedly connected to the bottom of the debris conduit, a vibrating rod penetrates and is rotatably connected to the side of the fixed frame, an eccentric shaft is fixedly connected to the side of the vibrating rod, a vibration guide plate is fixedly connected to the bottom of the fixed frame, the bottom of the vibration guide plate is fixedly connected to the top of the debris conduit, and the bottom of the pipe support is fixedly connected to the top of the support bottom plate. The rotation of the spiral compression plate drives the metal debris to move, thereby squeezing the metal debris, reducing the occupied space of the metal debris, and discharging it through the discharge port opened at the bottom of the debris conduit. Compared with the traditional briquetting device, a streamlined compression method is realized. While reducing the occupied space of the debris, a streamlined conveying method is maintained, thereby improving the conveying efficiency. While the spiral compression plate rotates, the drive shaft of the second motor drives the eccentric shaft to rotate. The center of the eccentric shaft is slightly offset relative to the vibrating rod. Therefore, when the eccentric shaft rotates, the vibrating rod is vibrated slightly. The vibration of the vibrating rod drives the vibration guide plate to vibrate. The vibration of the vibration guide plate drives the debris conduit to vibrate. The vibration of the debris conduit vibrates the metal debris inside the debris conduit, thereby further compressing the volume of the metal debris, reducing the occupied volume of the metal debris, and facilitating the collection of the metal debris.

[0014] The present invention provides a numerical control milling machine with a metal debris collection structure. It has the following beneficial effects:

[0015] 1. In this numerical control milling machine with a metal debris collection structure, a rotating table drives a fixing component to rotate to drive the workpiece to be adjusted at different angles, and a bidirectional moving device adjusts the position of the workpiece to cope with different machining positions. An arc-shaped baffle is arranged on the top of the fixed frame. Through the arc design, the flying debris is reflected and bounced back, and the debris is reflected back into the interior of the fixed frame, thereby reducing the possibility of the debris flying out, and facilitating the collection of the metal debris.

[0016] 2. The CNC milling machine with a metal chip collection structure is provided with a screw that rotates to drive a clamping plate closer to or away from the side of a fixed base plate through threads. The workpiece is placed on the top of the fixed base plate, so that the clamping plate drives the workpiece closer to the side of the fixed base plate to clamp the workpiece. Lifting blocks are arranged on the sides of the fixed base plate and the clamping plate, so that the clamping force is concentrated on the surface of the workpiece, which is more conducive to clamping the workpiece. The conductive slip ring connects the current of the first motor with the electromagnet column. While the screw rotates, the electromagnet column has a magnetic attraction effect, and the electromagnet column with an attraction effect drives the brake strip to rotate, so that the brake strip is retracted into the internal part of the driving sprocket. The rotation of the brake strip compresses the torsion spring, so that the torsion spring generates torsion. At this time, the driving sprocket rotates. When the first motor stops running, the electromagnet column loses the attraction to the brake strip, so that the brake strip automatically rotates back to the position where it extends out of the driving sprocket under the torsion of the torsion spring, so that the end of the brake strip is stuck into the groove opened on the side of the fixed base plate. One end of the brake strip abuts against the groove opened on the side of the fixed base plate, and the other end abuts against the side of the driving sprocket, so as to brake the driving sprocket, so as to maintain the clamping state after the workpiece is clamped. Compared with the traditional methods of using thread braking or using a motor to automatically clamp and use the motor for braking, this direct braking method can bear a greater load, so as to avoid the clamping failure of the workpiece caused by braking failure and prevent loosening during cutting.

[0017] 3. The CNC milling machine with a metal chip collection structure is provided with an intake fan that rotates to drive air to pass through the side of the heating wire and enter the inside of the intake grille under the driving action of the intake fan and reach the inside of the material guide pipe through the guide plate, so as to dry the metal chips, so as to separate the metal chips from the coolant. The metal chips fall inside the material guide pipe, and the coolant filter screen separates the metal chips from the coolant, and the fine metal chips and coolant are filtered and separated through the filtering action of the filtering device. The intake grille and the guide plate are at a certain angle inside the material guide pipe, and the chips fall on the upper surfaces of the intake grille and the guide plate, so as to extend the residence time of the chips inside the material guide pipe, so as to better separate the coolant from the metal chips. Thus, the filtration of the metal chips and the separation of the coolant are realized, which is conducive to the collection of the metal chips, and the coolant can be reused after filtration.

[0018] 4. The CNC milling machine with a metal chip collection structure is provided with a spiral compression plate that rotates to drive the metal chips to move, thereby extruding the metal chips, reducing the occupied space of the metal chips, and discharging them through the discharge port opened at the bottom of the chip conduit. Compared with the traditional briquetting device, it realizes a pipelined compression method, maintains a pipelined conveying method while reducing the occupied space of the chips, thereby improving the transfer efficiency. While the spiral compression plate rotates, the drive shaft of the second motor drives the eccentric shaft to rotate. The center of the eccentric shaft is slightly offset relative to the vibrating rod, so that the vibrating rod is slightly vibrated when the eccentric shaft rotates. The vibrating rod vibrates to drive the vibrating guide plate to vibrate, and the vibrating guide plate vibrates to drive the chip conduit to vibrate. The vibration of the chip conduit vibrates the metal chips inside the chip conduit, thereby further compressing the volume of the metal chips, reducing the occupied volume of the metal chips, and facilitating the collection of the metal chips.

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 work shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1 - Figure 2 , the present invention provides a technical solution: a numerical control milling machine with a metal debris collection structure includes a bracket bottom plate 1, a cutting bracket 2 is fixedly connected to the top of the bracket bottom plate 1, a milling device 3 is fixedly connected to the side of the cutting bracket 2, a fixing device 4 is fixedly connected to the top of the bracket bottom plate 1, a metal collection device 5 is fixedly connected to the top of the bracket bottom plate 1, the milling device 3 is arranged above the fixing device 4, and the metal collection device 5 is arranged at the bottom of the fixing device 4;

[0031] Working principle: The operator starts the fixing device 4 to clamp the workpiece to be processed, the metal collection device 5 collects the cut debris, the milling device 3 performs cutting operations on the workpiece. In addition to collecting the debris, the metal collection device 5 separates the coolant from the metal debris, collects the debris and compresses it. The separation of the coolant and the debris is realized, the coolant is filtered and reused, and the debris is compressed by the metal collection device 5 to reduce the occupied space, which is beneficial to subsequent processing.

[0032] The fixing device 4 includes a fixing frame 401. An arc-shaped baffle 402 is fixedly connected to the top of the fixing frame 401. A bidirectional moving device 403 is fixedly connected to the side surface of the inner wall of the fixing frame 401. A rotating table 404 is fixedly connected to the top of the bidirectional moving device 403. A fixing component 405 is fixedly connected to the top of the rotating table 404. The bottom of the fixing frame 401 is fixedly connected to the top of the support base plate 1. The fixing component 405 is arranged below the milling device 3.

[0033] Working principle: The operator manually places the workpiece on the top of the fixing component 405. The fixing component 405 clamps the workpiece. The rotating table 404 drives the fixing component 405 to rotate to drive the workpiece to be adjusted at different angles. The bidirectional moving device 403 adjusts the position of the workpiece, so as to cope with different machining positions. The arc-shaped baffle 402 is arranged on the top of the fixing frame 401. Through the arc design, the flying debris is reflected and bounced back, and the debris is reflected back into the interior of the fixing frame 401, thereby reducing the possibility of the debris flying out, which is beneficial to the collection of metal debris.

[0034] Please refer to Figure 1 - Figure 4 As shown in the figure, the present invention provides a technical solution: The fixing component 405 includes a fixing base plate 4051. A clamping plate 4052 is slidably connected to the top of the fixing base plate 4051 through a chute. A screw rod 4053 penetrates and is threadedly connected to the side surface of the fixing base plate 4051. One end of the screw rod 4053 is sleeved and fixedly connected with a conductive slip ring 4054. The screw rod 4053 penetrates the side surface of the fixing base plate 4051 and is rotatably connected to the fixing base plate 4051. A braking component 4055 is sleeved and fixedly connected to a part of the side surface of the screw rod 4053 on the side of the conductive slip ring 4054. A first motor 4056 is fixedly connected to the central position of the side surface of the fixing base plate 4051. A sprocket transmission mechanism 4057 is fixedly connected to the driving shaft of the first motor 4056. The driving shaft of the first motor 4056 is fixedly connected to the input end of the braking component 4055 through the sprocket transmission mechanism 4057. The bottom of the fixing base plate 4051 is fixedly connected to the top of the rotating table 404.

[0035] The braking assembly 4055 includes a driving sprocket 40551. A braking slot 40552 is formed on the side surface of the driving sprocket 40551. The inner wall of the braking slot 40552 is rotatably connected to a braking strip 40553 through a rotating pin. An electromagnet column 40554 penetrates and is fixedly connected to the side surface of the driving sprocket 40551. The electromagnet column 40554 extends into the interior of the braking slot 40552. A torsion spring 40555 is fixedly connected to the side surface of the braking strip 40553. One end of the torsion spring 40555 away from the braking strip 40553 is fixedly connected to the driving sprocket 40551. The driving sprocket 40551 is sleeved on the side surface of the screw rod 4053 and is fixedly connected to the screw rod 4053. The driving sprocket 40551 is arranged on the side surface of the conductive slip ring 4054. A slot adapted to the braking strip 40553 is formed on the side surface of the fixed bottom plate 4051.

[0036] Working principle: The operator starts the first motor 4056, and the drive shaft of the first motor 4056 drives the sprocket transmission mechanism 4057 to rotate. The rotation of the sprocket transmission mechanism 4057 drives the screw 4053 to rotate. The rotation of the screw 4053 drives the clamping plate 4052 to approach or move away from the side of the fixed base plate 4051 through the thread. The workpiece is placed on the top of the fixed base plate 4051, so that the clamping plate 4052 drives the workpiece to approach the side of the fixed base plate 4051 to clamp the workpiece. Pad blocks are provided on the sides of the fixed base plate 4051 and the clamping plate 4052, so that the clamping force is concentrated on the surface of the workpiece, which is more conducive to clamping the workpiece. The slip ring 4054 connects the current of the first motor 4056 with the electromagnet column 40554. While the screw 4053 is rotating, the electromagnet column 40554 has a magnetic attraction effect. The attraction effect of the electromagnet column 40554 drives the brake strip 40553 to rotate, so that the brake strip 40553 is retracted into the inside of the driving sprocket 40551. The rotation of the brake strip 40553 compresses the torsion spring 40555, so that the torsion spring 40555 generates torsion. At this time, the driving sprocket 40551 rotates. When the first motor 4056 stops running, the electromagnet column 40554 loses the attraction to the brake strip 40553, so that the brake strip 40553 automatically rotates back to the position extending out of the driving sprocket 40551 under the action of the torsion of the torsion spring 40555, so that the end of the brake strip 40553 is stuck into the groove opened on the side of the fixed base plate 4051. One end of the brake strip 40553 abuts against the groove opened on the side of the fixed base plate 4051, and the other end abuts against the side of the driving sprocket 40551, so as to brake the driving sprocket 40551, so as to maintain the clamped state after clamping the workpiece. Compared with the traditional method of using thread braking or using a motor to automatically clamp and using the motor to brake, this direct braking method can bear a larger load, so as to avoid the workpiece clamping failure caused by brake failure and avoid loosening during cutting.

[0037] Please refer to Figure 1 - Figure 7 As shown in the figure, the present invention provides a technical solution: The metal collection device 5 includes a material guide pipe 501. A drying device 503 is fixedly connected to the side of the material guide pipe 501. The bottom of the material guide pipe 501 is communicated with a compression device 504. A coolant filter screen 505 is fixedly connected to the bottom of the material guide pipe 501. The top of the material guide pipe 501 is communicated with the bottom of the fixed frame 401. The metal collection device 5 further includes a filtering device 502. The filtering device 502 is arranged at the bottom of the coolant filter screen 505. The bottom of the coolant filter screen 505 is fixedly connected to the top of the support base plate 1.

[0038] The drying device 503 includes an air inlet frame 5031, an electric heating wire 5032 is fixedly connected to the inner wall of the air inlet frame 5031, an air inlet fan 5033 penetrates and is fixedly connected to the side surface of the air inlet frame 5031, an air inlet grille 5034 is communicated with the side surface of the air inlet frame 5031, a guide plate 5035 is fixedly connected to the side surface of the air inlet grille 5034, the air inlet grille 5034 is fixedly connected to the side surface of the inner wall of the material guiding pipe 501, and the side surface of the air inlet frame 5031 is fixedly connected to the side surface of the material guiding pipe 501.

[0039] Working principle: The debris falls through the inside of the material guiding pipe 501. The operator turns on the power supply of the air inlet fan 5033. The air inlet fan 5033 rotates to drive air to pass by the side of the electric heating wire 5032 and enter the inside of the air inlet grille 5034 under the driving action of the air inlet fan 5033 and reach the inside of the material guiding pipe 501 through the guide plate 5035, so as to dry the metal debris, thereby separating the metal debris and the coolant. The metal debris falls in the material guiding pipe 501, and the metal debris and the coolant are separated under the action of the coolant filter screen 505. And through the filtering action of the filtering device 502, the fine metal debris and the coolant are filtered and separated. The air inlet grille 5034 and the guide plate 5035 are at a certain angle inside the material guiding pipe 501. The debris falls on the upper surfaces of the air inlet grille 5034 and the guide plate 5035, thereby prolonging the residence time of the debris in the material guiding pipe 501, so as to better separate the coolant and the metal debris. Thus, the filtration of the metal debris and the separation of the coolant are realized, which is beneficial to the collection of the metal debris, and the coolant can be reused after filtration.

[0040] Please refer to Figure 1 - Figure 9 , the present invention provides a technical solution: The compression device 504 includes a fixed frame 5041, a second motor 5042 is fixedly connected to the side surface of the fixed frame 5041, a debris conduit 5043 is fixedly connected to the side surface of the fixed frame 5041, a spiral compression plate 5044 is fixedly connected to the driving shaft of the second motor 5042, a pipe support 5045 is fixedly connected to the bottom of the debris conduit 5043, a vibrating rod 5046 penetrates and is rotatably connected to the side surface of the fixed frame 5041, an eccentric shaft 5047 is fixedly connected to the side surface of the vibrating rod 5046, a vibration guide plate 5048 is fixedly connected to the bottom of the fixed frame 5041, the bottom of the vibration guide plate 5048 is fixedly connected to the top of the debris conduit 5043, and the bottom of the pipe support 5045 is fixedly connected to the top of the support bottom plate 1.

[0041] Working principle: Metal debris enters the interior of the spiral compression plate 5044 through the debris conduit 5043. The operator turns on the power supply of the second motor 5042, and the drive shaft of the second motor 5042 drives the spiral compression plate 5044 to rotate. The rotation of the spiral compression plate 5044 drives the metal debris to move, thereby squeezing the metal debris, reducing the occupied space of the metal debris, and discharging it through the discharge port opened at the bottom of the debris conduit 5043. Compared with the traditional briquetting device, it realizes a pipeline compression method, maintains a pipeline transmission method while reducing the occupied space of the debris, thereby improving the transmission efficiency. While the spiral compression plate 5044 is rotating, the drive shaft of the second motor 5042 drives the eccentric shaft 5047 to rotate. The center of the eccentric shaft 5047 is slightly offset relative to the vibrating rod 5046. Therefore, when the eccentric shaft 5047 rotates, it vibrates the vibrating rod 5046 slightly. The vibration of the vibrating rod 5046 drives the vibration guide plate 5048 to vibrate. The vibration of the vibration guide plate 5048 drives the debris conduit 5043 to vibrate. The vibration of the debris conduit 5043 vibrates the metal debris inside the debris conduit 5043, thereby further compressing the volume of the metal debris, reducing the occupied volume of the metal debris, and facilitating the collection of the metal debris.
