Description

Technical Field

[0001] The present invention relates to the field of machine tool accessories, and specifically discloses a chip coiling device for a CNC lathe used in machining. Background Art

[0002] CNC machine tools are widely used in the field of machining, mainly for cutting metal materials. In metal machining, lathes are often used to perform operations such as opening holes, grinding, and planing on metals. During these processes, a large amount of spiral or arc-shaped coiled chips or coiled debris will be generated. If these coiled chips cannot be collected in a timely and effective manner, it will cause many adverse effects on the machining process. The common chip coiling collection devices on the market mainly set up collection troughs or collection boxes at the bottom of the machine tool, and rely on gravity to make the coiled chips fall naturally for collection.

[0003] For example, the invention patent with the patent application number CN117697525A discloses a chip coiling device for a CNC lathe used in machining. In the present invention, while the rotary feeding mechanism conveys the coiled chips into the centrifugal separation mechanism, the rotary feeding mechanism can also synchronously drive the centrifugal separation mechanism to rotate, thereby driving the coiled chips to rotate through the centrifugal separation mechanism, so as to throw off and separate the cutting fluid on the coiled chips by the centrifugal force of rotation. The separated cutting fluid is recovered by the cutting fluid recovery mechanism, which is convenient for the recycling of the cutting fluid, and the use of rotary separation makes it impossible for the cutting fluid to evaporate and generate harmful gases during the separation process, improving the safety of the staff; the gap between the two pressing rollers can be adjusted by the gap adjusting component, so that when the roller pressing mechanism processes coiled chips of different sizes, the gap between the two pressing rollers can be adjusted accordingly, making the gap between the two pressing rollers more suitable for the size of the coiled chips, thereby improving the squeezing and shrinking effect of the roller pressing mechanism on the coiled chips.

[0004] The existing chip coiling devices mainly rely on gravity or centrifugal force to collect the chips that fall to the bottom of the equipment. Its core structures include a screw conveyor, a chain plate type chip discharger and a centrifugal separation mechanism, but it is still limited to processing the chips that have left the processing area. For the coiled chips that are retained on the workbench due to adhesion of cutting fluid, interference of the tool path or occlusion of the fixture, some long coiled chips are highly flexible and easily wind and accumulate on the edge of the machine tool fixture or workbench, and cannot fall naturally by gravity, and manual intervention is required for cleaning, which affects the machining continuity. The prior art has not proposed an effective active collection solution, resulting in chip accumulation affecting the machining accuracy and the equipment maintenance efficiency. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a chip coiling device for a CNC lathe used in machining, so as to solve the technical problem that the existing chip coiling devices cannot actively clean the coiled chips accumulated on the machine tool workbench.

[0006] To achieve the above object, the present invention provides the following technical solution: A chip curling device for a numerically controlled lathe in machining, including a machine tool waste box, on which a machine tool protective cover is provided. An installation opening is provided on the machine tool protective cover. A machine tool workbench is provided on the machine tool waste box. On both sides of the machine tool protective cover, there are respectively two cleaning mechanisms for cleaning the chips accumulated on the machine tool workbench. When there are chips accumulated on the machine tool workbench, the cleaning mechanisms on both sides of the machine tool protective cover actively clean the chips, solving the problem that the existing chip curling devices cannot actively clean the chips on the machine tool workbench.

[0007] Further, the cleaning mechanism includes an installation cover, which is arranged at the installation opening on the machine tool protective cover. A first hydraulic rod is installed on the installation cover. The telescopic end of the first hydraulic rod is fixedly connected with a pushing frame. A bottom plate is arranged below the pushing frame. A first rotating shaft is rotatably connected to the bottom plate. The first rotating shaft penetrates through the pushing frame. A first fixing frame is arranged on the pushing frame. A first motor is installed on the first fixing frame. The power output shaft end of the first motor is fixedly connected with the first rotating shaft. A first gear is fixedly connected to the first rotating shaft. A second rotating shaft is rotatably connected between the bottom plate and the pushing frame. A second gear is fixedly connected to the second rotating shaft. The first gear and the second gear are connected by a chain drive.

[0008] There are two chip curling cleaning devices on the chain for cleaning the longer chips on the machine tool workbench. A dust suction device for sucking the smaller chips on the machine tool workbench is arranged on the bottom plate. A scraping plate device for scraping out the chips accumulated on the machine tool workbench is arranged on the pushing frame. By using chain drive, it can drive the chip curling cleaning devices to stably clean the longer chips on the machine tool workbench. This transmission method not only ensures the continuity and stability of the cleaning process, but also through the cyclic movement of the chain, can effectively expand the coverage range of the cleaning device, ensuring a comprehensive cleaning of a large area on the workbench. When the chip curling cleaning devices are difficult to handle some smaller chips, the equipped dust suction device can intervene in time and efficiently remove these fine chips through suction, avoiding the accumulation of small debris affecting the machining accuracy and equipment operation. At the same time, the design of the scraping plate device provides an additional solution for dealing with chip accumulation. It can scrape out a large amount of chips at one time, effectively cleaning both long chips and small chips, greatly improving the work efficiency.

[0009] Furthermore, the long coiled chip cleaning device includes a connecting rod fixedly connected below the chain. A fixing plate is provided on the connecting rod, and a plurality of dial rods are arranged on the fixing plate. An anti-winding component for preventing coiled chips from winding around the dial rods is arranged on the fixing plate. Multiple high-strength 40Cr alloy steel dial rods are used to perform directional cleaning on the surface of the machine tool workbench. Driven by the chain, they act synchronously to simultaneously push the longer coiled chips on the machine tool workbench out of the machine tool workbench, achieving efficient and batch coiled chip cleaning. The anti-winding component effectively prevents coiled chips from winding around the dial rods, ensuring a smooth and uninterrupted cleaning process.

[0010] Furthermore, the long coiled chip cleaning device further includes a second motor fixedly connected to the connecting rod. The power output shaft of the second motor is fixedly connected to the fixing plate. The second motor can independently control the rotation angle of the dial rods on the fixing plate, enabling the multiple dial rods to match the best cleaning posture according to the accumulation form of the coiled chips, effectively improving the cleaning efficiency and thoroughness.

[0011] Furthermore, the anti-winding component includes a sleeve plate slidably clamped on the plurality of dial rods, and a first fitting plate is fixedly connected to the sleeve plate. When coiled chips wind around the dial rods, the sleeve plate can simultaneously brush off the longer coiled chips wound on the dial rods through sliding, effectively solving the problem of coiled chips winding around the dial rods and ensuring the efficient progress of the cleaning process. Compared with the existing devices, this device realizes the automatic anti-winding function through a simple mechanical structure, eliminating the need for manual frequent cleaning of the wound coiled chips, greatly improving the continuity and efficiency of coiled chip cleaning.

[0012] Furthermore, the anti-winding component further includes two springs. Two fixing grooves are formed on the fixing plate, and the two springs are respectively installed in the two fixing grooves. The ends of the two springs away from the first hydraulic rod are fixedly connected to the sleeve plate. When it is necessary to clean the wound coiled chips on the dial rods, the sleeve plate can slide to the position of the coiled chips and brush off the coiled chips wound on the dial rods by means of the movement of the sleeve plate. After the cleaning is completed, the springs can automatically drive the sleeve plate to reset, eliminating the need for manual operation, saving time and labor costs. In addition, when the sleeve plate is not used for cleaning, the pulling force of the springs can keep the sleeve plate in a limited position, preventing it from interfering with the normal operation of the dial rods.

[0013] Further, the dust suction device includes a dust suction body fixedly connected to the bottom plate. The discharge end of the dust suction body is communicated with a dust collection box, and the air outlet end of the dust suction body is communicated with a corrugated pipe. A square pipe is communicated with the corrugated pipe, and a suction port is opened on the square pipe. The discharge end of the dust suction body is communicated with the dust collection box to achieve centralized collection of the coiled chips; while the air outlet end is communicated with the corrugated pipe, and the corrugated pipe is further connected to the square pipe with a suction port. Through the suction port on the square pipe, the smaller coiled chips on the machine tool workbench can be efficiently sucked. These coiled chips then enter the dust suction body through the corrugated pipe and are finally collected in the dust collection box. This design makes the dust suction process efficient and convenient, can quickly clean the difficult-to-handle small coiled chips on the workbench, and effectively avoids the influence of the accumulation of small coiled chips on the machining accuracy and efficiency of the machine tool.

[0014] Further, the dust suction device further includes a cross bar fixedly connected to the square pipe. A first chute is opened on the cross bar. A second hydraulic rod is arranged on the dust collection box, and the telescopic end of the second hydraulic rod is slidably clamped in the first chute. A second fitting plate that can fit with the first fitting plate is arranged on the square pipe. The cross bar is fixedly connected to the square pipe, and the first chute on the cross bar is slidably clamped and matched with the telescopic end of the second hydraulic rod on the dust collection box, so that the square pipe can flexibly move horizontally under the drive of the second hydraulic rod. In particular, the second fitting plate on the square pipe is precisely fitted with the first fitting plate on the sleeve plate. When the two are combined, the chain drives the fixed plate to move, and then drives the first fitting plate and the second fitting plate to move horizontally. With the flexibility of the corrugated pipe, the square pipe can move horizontally synchronously, greatly expanding the dust suction range and improving the collection efficiency of the coiled chips. In addition, when the first fitting plate and the second fitting plate are fitted, the telescopic movement of the second hydraulic rod can also drive the sleeve plate to move along the lever, and the coiled chips wound on the lever can be removed by means of the sleeve plate, eliminating the need for manual cleaning, saving time and effort, and effectively improving the work efficiency. Compared with the traditional dust suction device, through the ingenious cooperation of the hydraulic rod and the fitting plate, this device not only expands the dust suction area, but also realizes the function of automatically cleaning the lever, with significant improvements in automation and practicality.

[0015] Further, the scraper device includes a long plate, the long plate is fixedly connected to the push frame, a second slide groove is provided on the long plate, a limit block is slidably mounted in the second slide groove, a threaded rod is installed in the long plate, the threaded rod is threadedly connected to the limit block, one end of the threaded rod is slidably connected to the second slide groove, and the other end of the threaded rod passes through the long plate and the push frame, a third motor is fixedly connected to the push frame, the power output shaft of the third motor is fixedly connected to the threaded rod, a fixed block is slidably mounted on the limit block, a T-shaped scraper is fixedly connected below the fixed block, a plurality of adsorption holes with a radius greater than the radius of the lever are provided on the T-shaped scraper, and a plurality of magnetic ring sleeves with a radius greater than the radius of the lever are installed in the plurality of adsorption holes. When working, the T-shaped scraper can be adsorbed and fixed on the lever through the magnetic ring sleeve, so as to achieve the purpose of quickly replacing the lever with the T-shaped scraper. Driven by the second motor, the T-shaped scraper can rotate, scatter the chips on the machine tool workbench and push them to the area where the square tube can be adsorbed, effectively solving the problem of chip accumulation that is difficult to clean. Compared with existing devices, this mechanism, through the ingenious magnetic ring adsorption design and the second motor drive, not only realizes the rapid installation and removal of the T-shaped scraper, but also enhances the flexibility and thoroughness of chip cleaning, especially for chip that is difficult to clean with a lever.

[0016] The working principle and beneficial effects of this solution are:

[0017] During CNC lathe processing, chips are prone to accumulate on the machine tool workbench. The device drives the push frame to move through the first hydraulic rod, uses a visual sensor to prevent excessive extension and contraction, and the first motor drives the chain to rotate, drives the lever to rotate to a suitable angle to clean the chips. The chain rotation can also drive the fixed plate to move, so that the first fitting plate on the sleeve plate fits with the second fitting plate on the square tube. The chain rotation drives the square tube to move laterally to expand the dust suction area. The threaded rod is driven by the third motor to adsorb and fix the T-shaped scraper on the lever. The T-shaped scraper can simultaneously move some smaller chips driven by the chain, and can also scatter the chips to a position where the square tube can be adsorbed. The device drives the lever to move or replace it with a T-shaped scraper through the chain, and drives the first fitting plate to fit with the second fitting plate, and at the same time drives the square tube to move laterally, thereby solving the technical problem that the existing chip rolling device cannot actively clean the chips accumulated on the machine tool workbench, and effectively improves the cleaning efficiency and safety.

[0035] During specific implementation:

[0036] When the CNC lathe starts machining, chips will be generated on the machine tool workbench 3. When it is necessary to clean the chips accumulated on the machine tool workbench 3, first start the first hydraulic rod 5 in the mounting cover 4 at the mounting port 18. First, drive the pushing frame 6 to move away from the mounting cover 4 through the first hydraulic rod 5. During the movement, the visual sensor 8 is used to detect to prevent the first hydraulic rod 5 from overextending and retracting, which may cause the pushing frame 6 to interfere with the normal operation of the CNC lathe.

[0037] When the pushing frame 6 is moving, the first motor 13 on the first fixing frame 12 drives the first rotating shaft 11 to rotate. When the first rotating shaft 11 rotates, it will drive the first gear 15 to rotate. When the first gear 15 rotates, it will drive the chain 17 to start rotating through the second gear 16 on the second rotating shaft 14. The bottom plate 10 is fixedly connected with the pushing frame 6 through the reinforcing block 9. The first motor 13 drives the chain 17 to rotate. When the chain 17 rotates, it will drive the connecting rod 19 below to move. At this time, the second motor 20 on the connecting rod 19 can drive the fixing plate 21 to rotate. When the fixing plate 21 rotates, it will drive the shift rod 22 to rotate. After the second motor 20 drives the shift rod 22 to rotate to an appropriate angle, the first hydraulic rod 5 drives the shift rod 22 on the pushing frame 6 to approach the chips accumulated on the machine tool workbench 3. Then, the first motor 13 continuously drives the chain 17 to rotate, and the chain 17 drives the shift rod 22 to reciprocate and rotate, so as to push the chips on the machine tool workbench 3 to fall into the machine tool waste box 1 for collection.

[0038] When the lever 22 is used to curl the chips on the machine tool table 3, some longer chips are easily wound around the lever 22. At this time, the fixed plate 21 is continuously driven to move by the chain 17. When the fixed plate 21 moves, it will drive the sleeve plate 24 to move. After the first fitting plate 25 on the sleeve plate 24 is aligned with the second fitting plate 38 on the square tube 33, the second hydraulic rod 37 on the second fixing bracket 36 is started, and the slider 35 is pushed by the second hydraulic rod 37 to move towards the side close to the lever 22. When the slider 35 moves, it will drive the square tube 33 on the cross bar 34 to move. At this time, the square tube 33 will drive the second fitting plate 38 to fit with the first fitting plate 25 on the sleeve plate 24. After the first fitting plate 25 and the second fitting plate 38 are fitted, the second hydraulic rod 37 continuously drives the second fitting plate 38 on the square tube 33 to move. At this time, the second fitting plate 38 will push the first fitting plate 25, and at this time, the first fitting plate 25 will drive the sleeve plate 24 to slide on the lever 22 through the sliding hole 27. When the sleeve plate 24 moves, it stretches the spring 23 in the fixed slot 28 to store energy for subsequent reset. The chips wound around the lever 22 are withdrawn from the lever 22 through the sleeve plate 24. After the chips on the lever 22 are cleaned, the second hydraulic rod 37 contracts, driving the second fitting plate 38 to move towards the side close to the safety cover, and the sleeve plate 24 can be reset through the spring 23 in the fixed slot 28.

[0039] When some smaller chips on the machine tool table 3 cannot be removed by the lever 22, the first fitting plate 25 on the sleeve plate 24 is aligned with the second fitting plate 38 on the square tube 33 by the rotation of the chain 17. The square tube 33 is driven to move by the second hydraulic rod 37. At this time, the square tube 33 will drive the second fitting plate 38 to fit with the first fitting plate 25 on the sleeve plate 24. After the first fitting plate 25 and the second fitting plate 38 are fitted, the chain 17 is started to rotate. Since the square tube 33 is connected to the dust suction body 29 through the bellows 32, at this time, the chain 17 drives the square tube 33 to move horizontally. When the square tube 33 moves, it will drive the cross bar 34 to move horizontally on the slider 35. The horizontal movement of the square tube 33 driven by the chain 17 increases the area that can be sucked. At this time, the dust suction body 29 can be started, and the smaller chips on the machine tool table 3 are sucked through the square tube 33, then input into the dust suction body 29 through the bellows 32, and then the dust suction body 29 discharges the smaller chips into the dust collection box 30. When the dust collection box 30 is full of chips, the automatic door 31 can be automatically opened to discharge the chips into the machine tool waste box 1.

[0040] When there are a large number of relatively small coiled chips accumulated on the machine tool workbench 3, the coiled chips cannot be quickly cleaned by the dial rod 22. At this time, the chain 17 drives the dial rod 22 to move until it aligns with the adsorption hole 50 on the T-shaped scraper 47. After alignment, the third motor 45 on the third fixing frame 44 drives the threaded rod 43 to rotate. The threaded rod 43 drives the limit block 42 to slide in the second chute 49 on the long plate 41. When the dial rod 22 aligns with the adsorption hole 50, the threaded rod 43 drives the limit block 42 to move towards the side close to the dial rod 22. At this time, the limit block 42 will drive the T-shaped scraper 47 to gradually insert into the dial rod 22 through the adsorption hole 50. Since there is a magnetic ring sleeve 48 in the adsorption hole 50 and the dial rod 22 is made of 40Cr alloy steel, the dial rod 22 will be adsorbed to the magnetic ring sleeve 48 to prevent the T-shaped scraper 47 from falling during subsequent work. When the T-shaped scraper 47 completely moves onto the dial rod 22, since the fixing block 46 on the T-shaped scraper 47 is slidably clamped on the limit block 42, the chain 17 starts to drive the dial rod 22 to reverse in the initial direction, and the fixing block 46 on the T-shaped scraper 47 can be pulled out from the limit block 42. At this time, the third motor 45 drives the threaded rod 43 to drive the limit block 42 to move to the side away from the dial rod 22, and the limit block 42 interferes with the movement of the dial rod 22 during the subsequent movement of the dial rod 22.

[0041] After the T-shaped scraper 47 is installed on the dial rod 22, the chain 17 drives the T-shaped scraper 47 to move to the side close to the coiled chips. Then, the chain 17 reciprocates to drive the T-shaped scraper 47 to remove some coiled chips that cannot be cleaned by the dial rod 22. At this time, since one end of the T-shaped scraper 47 is T-shaped, the second motor 20 on the connecting rod 19 rotates to drive the dial rod 22 to rotate in cooperation with the rotation of the chain 17. The dial rod 22 drives the T-shaped scraper 47 to rotate, and the coiled chips can be dialed to the position where the square pipe 33 can suck by the T-shaped scraper 47. Then, the suction port 40 on the square pipe 33 starts to suck the coiled chips, and some adhered coiled chips can also be dispersed, making it faster and more convenient for the subsequent square pipe 33 to suck the coiled chips.

[0042] When the T-shaped scraper 47 is not needed, the operation of installing the T-shaped scraper 47 before can be repeated. First, the chain 17 drives the T-shaped scraper 47 to move to the side close to the limit block 42. Then, the threaded rod 43 drives the limit block 42 to align with the fixing block 46 on the T-shaped scraper 47. After alignment, the chain 17 drives the fixing block 46 on the T-shaped scraper 47 to move onto the limit block 42 and get stuck. At this time, the threaded rod 43 drives the limit block 42 to move to the side away from the dial rod 22, and the T-shaped scraper 47 is pulled out from the dial rod 22.

[0043] The above are only embodiments of the present invention, and common knowledge such as specific structures and characteristics known in the solution is not described in detail herein. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the present invention.
