Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chip removal devices for numerical control machine tools, in particular to a machine tool chip removal and cleaning device and method based on numerical control machine tool processing. BACKGROUND

[0002] If the chips (such as metal chips, powder) generated during the processing of a numerical control machine tool are not cleaned in time, they will accumulate in the processing area, causing tool wear, workpiece precision degradation, and even machine tool failure. The chip removal and cleaning device quickly transfers the chips to the collection box, ensuring continuous processing.

[0003] Referring to the machine tool chip removal and cleaning device disclosed in patent application No. CN115971960A, water is pumped into the guide pipe and the adjusting pipe, and finally sprayed out by the pipe valve. Not only can it wash the chips on the workpiece surface and the conveyor belt surface, but also can cool the workpiece, reducing the damage rate of the workpiece. The water flow is recycled by the graded filter screen and returned to the guide box, while the workpiece chips are blocked by the graded filter screen. When the guide box is pushed to the bottom of the machine tool discharge port, the push rod will contact and push the fixed block to rotate, and then the guide pipe will be driven to rotate, without manual rotation adjustment, improving the automation level of the device.

[0004] The above-mentioned machine tool chip removal and cleaning device in the prior art has the following defects in actual use: Most current machine tool chip removal devices are mainly designed to collect metal chips generated during processing from the machine tool working area to prevent chip accumulation from affecting processing precision and normal operation of the machine tool. However, the existing machine tool chip removal device only transfers and concentrates the chips, lacks the ability to compress the chips while collecting them, and cannot achieve integrated automatic operation of waste chip recycling, compression, and cutting fluid recycling. Since the fluffy metal chips cannot be compressed, the collection container will soon be filled with chips, requiring frequent cleaning and replacement, which not only increases the workload of the operator, but also occupies a large amount of storage space. In addition, additional equipment and manpower are required for subsequent compression and packaging of fluffy chips and cutting fluid recycling.

[0005] Therefore, the present application proposes a machine tool chip removal and cleaning device and method based on numerical control machine tool processing to solve the above problems. SUMMARY

[0006] In view of the deficiencies of the prior art, the machine tool chip removal and cleaning device and cleaning method based on numerical control machine tool machining are provided, which solve the problem that the function of the existing machine tool chip removal device is limited to the transfer and concentration of chips, lacks the ability to compress the collected chips, and cannot realize integrated automatic operation of waste chip recycling, compression, and cutting fluid recycling.

[0014] Furthermore, a transmission wheel is rotatably arranged directly below the disk.

Step 2: During the intermittent stop period when the chip shaping mechanism continues to rotate and enters the next stage, the pressurizing mechanism compresses the metal chips that have entered the chip shaping mechanism. Step 3: The chip shaping mechanism loads the compressed metal chips, which slide onto the top of the discharge plate under the combined action of gravity and internal thrust during subsequent rotation.

[0017] This invention provides a machine tool chip removal and cleaning device and method based on CNC machine tool machining. Compared with the prior art, it has the following advantages: 1. A chip removal and cleaning device and method for CNC machine tool processing, comprising a chip shaping mechanism and a power component. The shaping mechanism, driven by the power component, achieves intermittent rotation. During the intervals when the chip shaping mechanism stops rotating, its position is securely locked by the power component. This stable position facilitates the entry of subsequent cutting waste chips and prepares the pressurizing mechanism for compressing metal waste chips. Furthermore, while metal waste chips enter multiple shaping units, the pressurizing mechanism simultaneously injects them into the shaping units already loaded with metal waste chips. The pressure is applied to form metal scrap into a metal cake. At the same time, the metal scrap, which has already been compressed into a cake, is being squeezed while the pressurizing mechanism drives the air supply component. The gas pressure accelerates the speed at which the metal cake leaves the shaping unit. In this process, multiple extrusion columns, power components, air supply components, gas flow conversion components, and cutting and shaping mechanisms can form a highly efficient and compact linkage, working together to achieve a continuous process of metal scrap recycling, extrusion shaping, cutting fluid recovery, and metal cake unloading, greatly improving the recycling efficiency of metal scrap.

[0018] 2. A chip removal and cleaning device and method for CNC machine tool processing, which sets multiple shaping units in the chip shaping mechanism so that each shaping unit can load cutting chips during intermittent stop periods and provides multiple independent spaces for the compression and shaping of cutting chips. This allows the compressed metal chips to form a fixed-shape metal cake, which is convenient for subsequent storage and transportation. Moreover, during the compression of the metal chips, the cutting fluid remaining on the metal chips can be separated from the metal chips under the extrusion pressure and collected in the cutting fluid collection channel, which is convenient for subsequent recycling of cutting fluid. Furthermore, the shaping unit and the extrusion groove are designed separately, which can realize the quick assembly or disassembly of the shaping unit, thereby facilitating the cleaning or maintenance of each shaping unit.

[0019] 3. A chip removal and cleaning device and method for CNC machine tool processing, comprising a pressurizing mechanism, an air supply component, and a gas flow direction conversion component. When the pressurizing mechanism compresses the metal waste in the forming unit, the push rod can simultaneously apply pressure to the corresponding air supply component, thereby causing the air in the air inlet channels at two relative positions to flow through the gas flow direction conversion component to the air delivery channel located near the discharge plate. This allows the gas to enter the bottom of multiple corresponding support plates through the air delivery channel and vent at that position, pushing the support plates upward and providing power for the top plate to push the compressed metal cake out of the compression cylinder, thereby achieving the purpose of automatic unloading.

[0020] 4. A chip removal and cleaning device and method for CNC machine tool processing, which, by setting a secondary filtration component, can filter the cutting fluid a second time after it enters the cutting fluid collection channel, thereby facilitating subsequent processing of the cutting fluid. Furthermore, by pulling the secondary filtration component out of the cutting fluid collection channel as a whole, multiple filter plates can scrape off impurities and metal slag adhering to the inner wall of the cutting fluid collection channel, achieving the purpose of quickly cleaning the cutting fluid collection channel and reducing the difficulty of cleaning.

The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] This invention provides three technical solutions: a machine tool chip removal and cleaning device based on CNC machine tool processing, specifically including the following embodiments: like Figures 1-6The first embodiment is shown: a chip removal and cleaning device for CNC machine tool processing, including a CNC machine tool body 1 and a chip removal port opened on one side of the bottom of the CNC machine tool body 1. Below the chip removal port is a chip removal and cleaning mechanism for bulk collection of metal waste chips. The chip removal and cleaning mechanism includes: Two side plates 2 are arranged opposite each other on both sides of the chip discharge port, and a horizontal plate 3 is fixedly installed on the top of the two side plates 2. The chip shaping mechanism 4 is located between the two side plates 2. It is used to collect metal chips in batches during intermittent rotation, provide space for compressing and shaping the collected metal chips, and recover the cutting fluid remaining in the metal chips. The pressurizing mechanism 5 is located on the top of the horizontal plate 3 and is used to apply extrusion force to the metal chips collected in the chip shaping mechanism 4, so as to cooperate with the chip shaping mechanism 4 to complete the compression and shaping of metal chips and the discharge of metal cake. The guide plate 6 is fixedly mounted on the side walls of the two side plates 2. Multiple feeding troughs 7 for directional conveying of metal scrap are evenly distributed on the side wall of the guide plate 6 near the chip shaping mechanism 4. A discharge plate 8 is also fixedly mounted on the side wall of the two side plates 2 away from the guide plate 6. The positions of the multiple feeding troughs 7 correspond one-to-one with the positions of the multiple extrusion troughs 42. A vibration motor is installed at the bottom of the feeding trough 7. The vibration motor ensures that the chips falling on the surface of the feeding trough 7 are evenly distributed, and the chips can enter the compression cylinder 431 faster under the action of the vibration motor. Since the intermittent rotation time of the shaping unit 43 is a fixed value, the amount of chips entering the compression cylinder 431 is relatively stable. When the amount of chips entering the compression cylinder 431 is small, the extrusion column 56 enters the compression cylinder 431 to the same depth at the corresponding position, reducing the extrusion pressure between the chips and resulting in a denser chip cake.

[0026] like Figures 8-16 , Figure 20The second embodiment is shown, which differs from the first embodiment in that: the chip shaping mechanism 4 includes a shaping roller 41 rotatably disposed between two side plates 2 and end caps detachably disposed at both ends of the shaping roller 41. Multiple sets of chip shaping components are evenly provided on the outer wall of the shaping roller 41. Each set of chip shaping components is composed of multiple equidistantly arranged extrusion grooves 42. A shaping unit 43 is detachably disposed inside each extrusion groove 42 by bolts. Multiple second filter holes 44 for discharging cutting fluid are also evenly provided on the inner wall of the extrusion groove 42. A cutting fluid collection channel 45 for collecting cutting fluid is provided at the center of the inner part of the shaping roller 41. A cutting fluid delivery channel is provided between the multiple extrusion grooves 42 and the cutting fluid collection channel 45. A one-way valve is provided in each cutting fluid delivery channel, which only allows cutting fluid to flow to the cutting fluid collection channel 45. A transmission pipe 47 connected to the cutting fluid collection channel 45 is also fixedly provided at one end of the shaping roller 41. The bottom of the inner cavity of the extrusion groove 42 is provided with a vent hole that communicates with the gas delivery channel 49.

[0027] In this embodiment, each set of waste material shaping components has an air inlet channel 48 at both ends, and the inner cavities of the two air inlet channels 48 are connected. An air delivery channel 49 is provided inside the shaping roller 41 and below the waste material shaping component. An air guide pipe is fixedly installed inside one end of the air delivery channel 49. The air guide pipe passes through the shaping roller 41 and the end cap and extends to the outside. Multiple exhaust holes 411 are provided on the side wall of the shaping roller 41. Each exhaust hole 411 is connected to the corresponding air inlet channel 48. An air supply component 410 is provided inside each air inlet channel 48. The air supply component 410 includes a piston column 4101 that is sealed and slidably installed inside the air inlet channel 48. Guide rods 4102 are fixedly installed on both sides of the bottom of the piston column 4101. A second spring 4103 is slidably sleeved on the outer wall of the guide rod 4102 and located between the piston column 4101 and the air inlet channel 48. Lifting holes are provided at the bottom of the inner cavity of the air intake channel 48 and at the positions corresponding to the two guide rods 4102. The guide rods 4102 are slidably disposed in the lifting holes at the corresponding positions. The limit position of the air supply component 410 is not lower than the position of the exhaust hole 411. The end of the air guide pipe is flush with the outer wall of the end cap to ensure that the air guide pipe can be sealed and slidably disposed on the outer wall of the annular air pipe 4121. In this embodiment, a secondary filtration assembly 46 is detachably installed inside the cutting fluid collection channel 45 for secondary filtration of the incoming cutting fluid and rapid cleaning of the cutting fluid collection channel 45. The secondary filtration assembly 46 includes a pull rod 461 and multiple filter plates 462 uniformly fixedly sleeved on the outer wall of the pull rod 461. One end of the pull rod 461 slides through the end cap and is fixedly provided with a handle. A sealing plug 463 is also fixedly sleeved on the outer wall of the pull rod 461. The sealing plug 463 is detachably installed inside the end cap. A through hole adapted to the structure of the sealing plug 463 is opened at the center of the end cap. The sealing plug 463 and the end cap are detachably connected by bolts. When the filter plate 462 furthest from the sealing plug 463 is installed inside the cutting fluid collection channel 45, it is in close contact with the inner wall of one end of the cutting fluid collection channel 45. An avoidance groove is opened on the outer wall of the side plate 2 to facilitate the installation and removal of the sealing plug 463.

[0028] In this embodiment, the shaping unit 43 includes a compression cylinder 431 and a plurality of first filter holes 432 evenly opened on the lower part of the inner wall of the compression cylinder 431. A relief groove 433 is provided at the center of the bottom of the compression cylinder 431. A top plate 434 is slidably and sealed inside the relief groove 433. A support rod is fixedly provided at the bottom of the top plate 434. The bottom end of the support rod slides through the relief groove 433 and is fixedly provided with a support plate 435. A lifting groove adapted to the outer diameter of the support plate 435 is provided at the bottom of the compression cylinder 431. The support plate 435 is slidably and sealed inside the lifting groove. A first spring 436 is slidably sleeved on the outer wall of the support rod between the lifting groove and the support plate 435. The area of ​​the inner wall of the extrusion groove 42 near the second filter hole 44 is recessed inward to form a larger inner diameter movement space, which is used to reserve a gap for the flow of cutting fluid between the second filter hole 44 and the first filter hole 432.

[0029] In this embodiment, a gas flow conversion component 412 is also provided on the outer wall of one of the side plates 2. The gas flow conversion component 412 includes an annular air pipe 4121. An air inlet 4122 and an air outlet 4123 communicating with the interior are respectively opened on the outer wall of the annular air pipe 4121. The annular air pipe 4121 is fixedly installed on the side wall of one of the side plates 2, and the side wall of the annular air pipe 4121 is slidably connected to the outer wall of one of the end caps. During the intermittent rotation of the shaping roller 41, during each intermittent stop of the shaping roller 41, the air outlet 411 and the air inlet 4122 are always opposite each other and form a connected gas channel. At this time, the air outlet 4123 and the end of a lower air guide pipe are directly opposite each other. The air outlet 4123 and the air guide pipe form a gas transmission channel, while the gas transmission channels 49 at other positions are blocked and sealed by the side wall of the annular air pipe 4121.

[0030] like Figure 7 , Figures 17-19The third embodiment is shown, which differs from the second embodiment in that: the pressurizing mechanism 5 includes a first vertical plate 51 and a second vertical plate 52 arranged opposite to each other. A slide rail 53 is fixedly installed on the side wall of the second vertical plate 52 relative to the first vertical plate 51. A sliding sleeve 54 is slidably sleeved on the outer wall of the slide rail 53. A lifting plate 55 is slidably sleeved on the outer wall of the sliding sleeve 54 and the first vertical plate 51. A plurality of mounting through holes are evenly opened on the top of the lifting plate 55. A pressing column 56 is fixedly installed inside each mounting through hole. A push rod 57 is fixedly installed on both sides of the bottom of the lifting plate 55. The lifting plate 55 completes intermittent lifting and lowering by the drive of the power component. The positions of multiple extrusion columns 56 correspond one-to-one with the positions of multiple extrusion grooves 42, and the outer diameter of the extrusion column 56 is adapted to the inner diameter of the compression cylinder 431. The positions of the two push rods 57 are adapted to the positions of the two air intake channels 48. When the air intake channel 48 rotates to the position opposite to the push rod 57, the push rod 57 can push the air intake channel 48 to move down during its downward movement. The first vertical plate 51 and the second vertical plate 52 are respectively fixedly installed on the top of the two side plates 2.

[0031] In this embodiment, the power assembly includes a drive shaft 58 that rotates through the side plate 2. A disc 59 and a limiting disc 510 are fixedly mounted on the outer wall of the drive shaft 58 in sequence. A drive rod 511 is also fixedly mounted on the outer wall of the disc 59. A drive rod 512 is eccentrically mounted on the side wall of the disc 59. The other end of the drive rod 512 is rotatably mounted on the side wall of the sliding sleeve 54.

[0032] In this embodiment, a transmission wheel 513 is rotatably arranged directly below the disk 59. Multiple arc-shaped limiting grooves 514 are evenly opened on the outer wall of the transmission wheel 513, and a transmission groove 515 is opened on the outer wall of the transmission wheel 513 between two adjacent arc-shaped limiting grooves 514. The transmission shaft 58 is driven to rotate by a servo motor 516. A notch is provided on one side of the outer wall of the limiting plate 510. When the complete arc-shaped area of ​​the limiting plate 510 away from the notch is located in the arc-shaped limiting groove 514, it can restrict the rotation of the transmission wheel 513. When the notch position meets the area of ​​the arc-shaped limiting groove 514, the transmission wheel 513 can rotate. When a part of the notch position of the limiting plate 510 meets one of the arc-shaped limiting grooves 514, the drive rod 511 just slides into one end of one of the transmission grooves 515 and pushes the transmission wheel 513 to rotate intermittently. The transmission wheel 513 is fixedly sleeved on the outer wall of the transmission tube 47. The transmission tube 47 rotates through the side plate 2 and extends to the outside. The servo motor 516 is fixedly installed on the outer wall of the side plate 2, and the output shaft of the servo motor 516 and the transmission shaft 58 are connected by a coupling.

[0033] This invention also provides a cleaning method for a machine tool chip removal and cleaning device based on CNC machine tool processing, the method comprising the following steps: Step 1: During the intermittent rotation and stoppage of the chip shaping mechanism 4, the cutting chips that fall on the top of the guide plate 6 are evenly fed into different positions inside the chip shaping mechanism 4 through multiple feeding troughs 7. The specific process is as follows: The chip shaping mechanism 4 treats the slag-like cutting chips. During operation, the metal chips formed in the CNC machine tool body 1 fall onto the top of the guide plate 6 through the chip discharge port under the action of gravity. Under the action of the vibration motor, the metal chips falling onto the top of the guide plate 6 are evenly distributed in multiple feeding grooves 7. The metal chips slide down through multiple feeding grooves 7 to the position close to the outer wall of the shaping roller 41. During an intermittent stop during the intermittent rotation of the chip shaping mechanism 4, multiple shaping units 43 of one group are exactly opposite to the bottom chip discharge port of the feeding groove 7. The metal chips slide down into the compression cylinder 431 at the corresponding position under the action of gravity and vibration. Then, the servo motor 516 continues to drive the transmission shaft 58 to rotate. The transmission shaft 58 drives the disc 59, the limit disc 510 and the drive rod 511 to rotate synchronously. After the drive rod 511 enters one of the transmission grooves 515, it moves the transmission wheel 513 to rotate at a fixed angle, so that the shaping roller 41 is synchronously driven. As the wheel 513 rotates at a preset angle, the multiple shaping units 43 loaded with metal scrap gradually rotate to the top, that is, the multiple shaping units 43 are directly below the pressurizing mechanism 5. After the drive rod 511 just finishes toggling the rotation of the transmission wheel 513, the arc-shaped surface of the outer wall of the limiting disk 510 opposite to the notch enters one of the arc-shaped limiting grooves 514. The transmission wheel 513 cannot rotate due to the combined action of the arc-shaped limiting groove 514 and the limiting disk 510. At this time, the disc 59 drives the transmission rod 512 to pull the sliding sleeve 54 down, and the multiple extrusion columns 56 enter the compression cylinder 431 in the corresponding position and in a stationary state. The metal scrap in the compression cylinder 431 is reduced in volume due to the extrusion of the extrusion columns 56. It should be noted that the interval time of each shaping roller 41 is a fixed value. During the interval time, the amount of scrap entering the shaping unit 43 is in a relatively stable state. In this state, the metal scrap will not be completely compressed, and a certain gap will remain between the scrap.

[0034] Under the pressure of the extrusion column 56, the cutting fluid remaining on the metal scrap is squeezed out and enters the cutting fluid collection channel 45 through the second filter hole 44 and the cutting fluid delivery channel. After being filtered again by multiple filter plates 462, the cutting fluid is discharged to the outside through the single discharge port transmission pipe 47. At the same time, the two push rods 57 push the piston column 4101 at the corresponding position to move down along the intake channel 48. The piston column 4101 compresses the air in the intake channel 48 and passes it through the exhaust port 411 and the intake port 4. 122 enters the annular air pipe 4121. The gas passes through the inner cavity of the annular air pipe 4121 and enters the air conveying channel 49 located near the discharge plate 8 through the exhaust port 4123. The air conveying channels 49 in other positions are blocked by the side wall of the annular air pipe 4121. The gas pushes the support plate 435 to move upward along the lifting groove through the air conveying channel 49 and the air hole at the bottom of the extrusion groove 42. After the top plate 434 moves upward, it pushes the compressed metal cake away from the compression cylinder 431. The metal cake slides out of the compression cylinder 431 under the action of gravity.

[0035] When the transmission rod 512 moves upward and pushes the multiple extrusion columns 56 back to their original positions, the drive rod 511 re-enters the transmission groove 515 at the next position and once again drives the transmission wheel 513 to rotate, thus entering the next process of recycling metal scrap and compressing it.

[0036] Step 2: During the intermittent stop period when the chip shaping mechanism 4 continues to rotate and enters the next stage, the pressurizing mechanism 5 compresses the metal chips that enter the chip shaping mechanism 4. Step 3: The chip shaping mechanism 4 loads the compressed metal chips, which slide onto the top of the discharge plate 8 under the combined action of gravity and internal thrust during the subsequent rotation.
