Description

Technical Field

[0001] The present invention relates to the technical field of machining, and particularly relates to a machining center with a chip removal and cleaning structure. Background Art

[0002] During the machining process, materials are cut into various shapes of waste chips, such as coiled, clumped, strip-shaped, block-shaped, and granular. If these waste chips cannot be cleaned in a timely and effective manner, it will have many adverse effects on the normal operation and machining accuracy of the machining center. On the one hand, the accumulation of waste chips in the machining area may interfere with the normal cutting of the tool and the workpiece, resulting in a decrease in machining accuracy and even damage to the tool. On the other hand, the long-term accumulated waste chips may enter key parts such as the transmission components and guide rails of the machine tool, accelerating mechanical wear, shortening the service life of the machine tool, and increasing the equipment maintenance cost.

[0003] Chinese Patent CN117884956B discloses a horizontal five-axis turning and milling compound machining center, including: a workpiece spindle for clamping a workpiece; a machining spindle for machining the workpiece; the machining spindle can move linearly along the X-axis, Y-axis, and Z-axis directions; the machining spindle can rotate around the A-axis, and the A-axis is not coaxial with the X-axis, Y-axis, and Z-axis; a milling head and a turning tool are provided on the machining spindle, and the rotation of the machining spindle around the A-axis can make the milling head or the turning tool face the workpiece respectively and machine the workpiece; it also includes a tool magazine, and replacement tools are provided in the tool magazine. The rotation of the machining spindle around the A-axis can make the tool axis of the milling head parallel to the axis of the replacement tool.

[0004] In the actual use process, it is found that due to the high-viscosity and ductile strip-shaped aluminum chips generated by aluminum alloy machining, after being mixed with the cutting fluid, the viscosity will be further increased, and it is extremely easy to adhere and wind around the surface of components such as the chip removal screw rod of the machining center. As the amount of aluminum chip winding increases, the chip removal channel will gradually be blocked, resulting in the inability of waste chips to be discharged smoothly. At the same time, the friction between the high-viscosity aluminum chips and the chip removal components increases, accelerating the wear of the equipment, not only increasing the maintenance cost, but also possibly causing waste chips to accumulate in the machining area due to poor chip removal, interfering with the normal cutting of the tool and the workpiece, and reducing the machining accuracy.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0026] Example 1 like Figures 1 to 7 As shown, this embodiment provides a machining center with a chip removal and cleaning structure, including a ball squeezing mechanism 2, the ball squeezing mechanism 2 including: a longitudinal crushing assembly 21 provided on a machine tool 100, a transverse crushing assembly 22 provided below the longitudinal crushing assembly 21, and a ball pressing assembly 23 provided below the transverse crushing assembly 22; The strip-shaped chips produced by processing first pass through the longitudinal crushing component 21, which cuts the strip-shaped chips into multiple segments in the longitudinal direction, and then passes through the transverse crushing component 22, which cuts the longer chips in the transverse direction into multiple segments. The ball pressing component 23 squeezes the small chips after cutting into balls, which reduces the contact area and thus reduces the stickiness of the chip surface for easy transportation to prevent blockage.

[0027] Further, if Figures 2 to 4 As shown, the longitudinal crushing assembly 21 includes: A base 211, the base 211 being arranged on the machine tool 100 via fasteners; A second motor 212 , the second motor 212 is mounted on the base 211 ; A longitudinal cutting roller 213 is rotatably disposed inside the base 211 and is provided with two rollers side by side, one of which is drivingly connected to the output shaft of the second motor 212 for longitudinally cutting strip-shaped chips; The first gear 214 is in driving connection with the longitudinal cutting rollers 213 and is used to drive the two longitudinal cutting rollers 213 to rotate synchronously.

[0028] In this embodiment, by providing the longitudinal crushing assembly 21, longitudinal cutting and segmentation of the strip-shaped chips are achieved, thereby providing crushed chips with appropriate sizes for subsequent transverse crushing and briquetting processes, and preventing the chips from winding and blocking the chip discharge channel due to excessive length.

[0029] Specifically, the output shaft of the second motor 212 is in transmission connection with one of the longitudinal cutting rollers 213. When the second motor 212 is started, it drives the longitudinal cutting roller 213 to rotate. The first gear 214 is in transmission connection with the two longitudinal cutting rollers 213, and through gear transmission, the two longitudinal cutting rollers 213 are kept rotating synchronously and in opposite directions to form a shearing force. After the strip-shaped chips enter the interior of the base body 211, they are clamped and cut by the two rotating longitudinal cutting rollers 213 and longitudinally cut into multiple segments. The base body 211 is fixed to the machine tool by fasteners, providing a stable installation foundation for the entire longitudinal crushing assembly, ensuring that the assembly does not shake during the cutting process and guaranteeing the cutting accuracy.

[0030] It should be noted that the setting of the fasteners facilitates the installation and disassembly of the base body 211, and is convenient for later maintenance or replacement of the longitudinal cutting rollers 213. In addition, the longitudinal crushing assembly and the lower transverse crushing assembly are arranged corresponding to each other vertically, so that the chips can directly fall into the transverse crushing assembly for the next treatment after longitudinal cutting, optimizing the chip crushing process.

[0031] Furthermore, as Figures 2 to 4 shown, the transverse crushing assembly 22 includes: A third motor 221, which is installed on the base body 211; Transverse cutting rollers 222, which are rotatably arranged inside the base body 211 and there are two arranged side by side. One of them is in transmission connection with the output shaft of the third motor 221 and is used for transversely cutting the strip-shaped chips; A second gear 223, which is in transmission connection with the transverse cutting rollers 222 and is used for driving the two transverse cutting rollers 222 to rotate synchronously.

[0032] In this embodiment, by providing the transverse crushing assembly 22, transverse segmentation cutting of the chips after longitudinal cutting is achieved, thereby further fragmenting the chips and providing smaller-sized debris for the briquetting assembly, effectively reducing the viscosity of the chips and preventing blockage of the chip discharge channel.

[0033] Specifically, the third motor 221 is fixedly installed on the side of the base body 211, and its output shaft is directly connected to the shaft end of one of the transverse cutting rollers 222. When the third motor 221 is powered on and operates, it drives the transverse cutting roller 222 to rotate. The two transverse cutting rollers 222 are arranged side by side inside the base body 211, and the shaft ends are supported by bearings. At the same time, the second gears 223 on the two transverse cutting rollers 222 are meshed with each other, and the two transverse cutting rollers 222 are kept rotating synchronously and in opposite directions through gear transmission to form a transverse shearing area; the chips after longitudinal crushing fall from above the base body 211, enter between the two transverse cutting rollers 222, and are clamped by the rotating cutting rollers and cut transversely into shorter chips.

[0034] It should be noted that the third motor 221 and the shaft end of the transverse cutting roller 222 are connected by a key to ensure the reliability of power transmission.

[0035] Furthermore, as Figures 5 to 7 shown, the briquetting assembly 23 includes: A briquetting plate 231, which is arranged at the bottom of the base body 211 and is provided with multiple semicircular tracks for extruding chips inside. A docking plate 232; A sliding rod 233, which is arranged on the docking plate 232 and penetrates through the briquetting plate 231. A mounting plate 234, which is arranged at one end of the sliding rod 233. A first spring 235, which is sleeved on the sliding rod 233 and is located between the briquetting plate 231 and the mounting plate 234. A cylinder 236, which is installed on the mounting plate 234. A pressing plate 237, which is connected to the ejector rod of the cylinder 236. A pressing rod 238, which is provided with a plurality of pressing rods 238 on the pressing plate 237 and penetrates through the briquetting plate 231. A hemispherical groove is opened at one end of the pressing rod 238 close to the docking plate 232 for extruding chips into balls. A baffle 239, which is arranged on the base body 211. When the ejector rod of the cylinder 236 contracts and encounters the baffle 239, it drives the cylinder 236 to move towards the briquetting plate 231 side, thereby separating the briquetting plate 231 and the docking plate 232 to let the chip balls fall.

[0036] In this embodiment, through the ball pressing assembly 23, the cylinder 236 drives the pressure rod 238 to squeeze in the semicircular track of the ball pressing plate 231, and cooperates with the docking plate 232 to form a closed spherical space, thereby realizing the function of squeezing the broken chips into balls, and then reducing the viscosity by reducing the chip contact area to prevent chip removal blockage; at the same time, the baffle 239 and the cylinder 236 are linked to separate the ball pressing plate 231 and the docking plate 232 after the ball pressing is completed, so that the chip balls fall smoothly.

[0037] In detail, the cylinder 236 is fixed on the mounting plate 234, and its push rod is connected to the pressure plate 237. When the cylinder 236 is extended, it drives the pressure plate 237 to move downward, so that the pressure rod 238 passes through the ball pressure plate 231 and is inserted into the docking plate 232. The pressure rod 238 slides and fits with the semicircular track in the ball pressure plate 231. The hemispherical groove at the end of the pressure rod 238 and the docking plate 232 together form a complete spherical cavity. The broken chips are squeezed into balls in the cavity. The sliding rod 233 passes through the ball pressure plate 231 and is connected to the docking plate 232. The connecting plate 232 is fixed, the mounting plate 234 is mounted on the slide bar 233, and the first spring 235 is located between the ball pressure plate 231 and the mounting plate 234. When the cylinder 236 contracts, the push rod drives the mounting plate 234 backward. At this time, the baffle 239 prevents the mounting plate 234 from moving further, forcing the cylinder 236 to move forward, forcing the first spring 235 to contract, thereby driving the slide bar 233 and the connecting plate 232 forward, separating the connecting plate 232 from the ball pressure plate 231, and allowing the chip balls to fall through the gap. The first spring 235 provides the reset force after the cylinder contracts.

[0038] It should be noted that the ball pressure plate 231 is fixedly connected to the bottom of the base 211 to ensure a stable position during the extrusion process; the docking plate 232 forms a movable component with the mounting plate 234 through the slide rod 233, which is convenient for separation from the ball pressure plate 231; multiple pressure rods 238 are evenly distributed on the pressure plate 237, which can squeeze multiple chips at the same time to improve efficiency; the installation position of the baffle 239 has been precisely calculated to ensure that when the cylinder 236 push rod is retracted to the limit position, the separation gap between the docking plate 232 and the ball pressure plate 231 is sufficient to allow the chip ball to fall, while avoiding excessive separation and chip leakage.

[0039] Further, if Figures 2 to 3 As shown, it also includes a filtering mechanism 1, and the filtering mechanism 1 includes: A first motor 101 , wherein the first motor 101 is mounted on the base 211 ; A liquid collecting shell 102, the liquid collecting shell 102 is drivingly connected to the output shaft of the first motor 101, and has a liquid outlet at the bottom; An arc-shaped filter screen 103 is provided on the liquid collecting housing 102 and is used to separate chips and cutting fluid; The liquid drainage arc plate 104 is arranged on the base body 211 and is located below the liquid collection shell 102, and is inclined horizontally downward to drain the cutting fluid.

[0040] In this embodiment, by setting the filtering mechanism 1, the first motor 101 drives the liquid collection shell 102 to rotate, and cooperates with the arc-shaped filter screen 103 wrapped outside the liquid collection shell 102 to separate the cutting fluid and the chips, thereby reducing the pollution of the cutting fluid by the chips, facilitating the recycling of the cutting fluid, and at the same time reducing the surface viscosity of the chips to prevent chip discharge blockage.

[0041] Specifically, the first motor 101 is fixedly installed on the base body 211, and its output shaft is in transmission connection with the liquid collection shell 102. When the first motor 101 is started, it drives the liquid collection shell 102 to rotate around the axis. The bottom of the liquid collection shell 102 is provided with a liquid outlet, and the outside is wrapped with an arc-shaped filter screen 103. After the mixture of the cutting fluid and the chips enters the liquid collection shell 102, with the rotation of the liquid collection shell 102, the cutting fluid is filtered out through the mesh holes of the arc-shaped filter screen 103 and flows to the liquid drainage arc plate 104 below through the liquid outlet at the bottom of the liquid collection shell 102. The liquid drainage arc plate 104 is inclined horizontally downward to guide the cutting fluid to slide down along the arc plate and be discharged, while the chips are intercepted on the arc-shaped filter screen 103 and are flipped 180° to drop the chips onto the longitudinal crushing assembly 21, realizing the separation of the chips and the cutting fluid.

[0042] Further, as Figures 8 to 10 shown, it further includes a conveying mechanism 3, and the conveying mechanism 3 includes: A chip discharge groove 301 is opened at the bottom of the machine tool 100; A screw rod 302 is arranged inside the chip discharge groove 301; A fourth motor 303, the output shaft of the fourth motor 303 is in transmission connection with the screw rod 302.

[0043] In this embodiment, by setting the conveying mechanism 3, the fourth motor 303 drives the screw rod 302 to rotate in the chip discharge groove 301, realizing the function of conveying the extruded spherical chips from the bottom of the machine tool 100 to the designated collection position, thereby avoiding chip accumulation and blocking the chip discharge channel and ensuring the normal operation of the machining center.

[0044] Specifically, the fourth motor 303 is fixedly installed at the bottom of the machine tool 100, and its output shaft is in transmission connection with one end of the screw rod 302 through a coupling. The screw rod 302 is arranged inside the chip discharge groove 301. The chip discharge groove 301 is opened along the length direction of the bottom of the machine tool 100, and the chip balls directly fall into the inside of the chip discharge groove 301.

[0045] Further, as Figures 8 to 10 shown, it further includes a cleaning mechanism 4, and the cleaning mechanism 4 includes: An arc-shaped chute 401, the arc-shaped chute 401 is arranged around the chip removal groove 301; The arc-shaped cover plate 402 has a rotating device in the arc-shaped chute 401 and is provided with teeth at one end. The arc-shaped cover plate 402 can rotate in the arc-shaped chute 401, thereby covering the chip removal groove 301 to form a cylinder, which is convenient for high-pressure water cleaning of the screw rod 302; Driving teeth 403, wherein the driving teeth 403 are engaged with the teeth on the arc-shaped cover plate 402; a fifth motor 404 , wherein an output shaft of the fifth motor 404 is drivingly connected to the driving gear 403 ; A water pump 405 , wherein the water pump 405 is installed on the machine tool 100 ; a water outlet pipe 406 , one end of which is connected to the water outlet of the water pump 405 , and the other end of which is connected to the interior of the chip discharge groove 301 ; A collection box 407 is provided on one side of the machine tool 100; The filter plate 408 is arranged inside the collecting box 407 and is used to separate chips and flushing water.

[0046] In this embodiment, a cleaning mechanism 4 is provided, in which the fifth motor 404 drives the driving gear 403 to rotate, driving the arc cover plate 402 to rotate in the arc chute 401 to cover the chip groove 301, and cooperates with the water pump 405 to inject high-pressure water into the chip groove 301 through the outlet pipe 406 to realize the cleaning function of the screw rod 302, thereby removing the chips attached to the surface of the screw rod, preventing the chips from accumulating and blocking the chip removal channel, and extending the service life of the screw rod.

[0047] Specifically, the fifth motor 404 is fixedly mounted on the machine tool 100, and its output shaft is in transmission connection with the driving gear 403. When the fifth motor 404 is started, the driving gear 403 rotates and engages with the teeth at one end of the arc-shaped cover plate 402, driving the arc-shaped cover plate 402 to rotate within the arc-shaped chute 401 surrounding the chip flute 301, until the arc-shaped cover plate 402 completely covers the chip flute 301, forming a closed cylindrical structure. At this time, the water pump 405 pressurizes the external water source and sends it into the chip flute 301 through the outlet pipe 406. The high-pressure water flow flushes the chips on the surface of the screw rod 302. The washed chips and the water flow flow along the chip flute 301 to the collection box 407 on the side of the machine tool 100. The filter plate 408 inside the collection box 407 separates the mixture, and the chips remain on the top of the filter plate. The flushing water flows through the filter plate and flows into the bottom of the collection box for recycling. Among them, the arc-shaped chute 401 provides a rotating track for the arc-shaped cover plate 402 to ensure that the cover plate accurately covers the chip discharge groove; the driving gear 403 meshes with the teeth of the arc-shaped cover plate 402 for transmission to ensure smooth rotation of the cover plate; the high-pressure water flow design of the water pump 405 can effectively wash away the chips adhered to the surface of the screw rod; the mesh size of the filter plate 408 is designed to separate chips and allow water to pass through.

[0048] Furthermore, as Figures 11 to 14 shown, it further includes a support mechanism 5, and the support mechanism 5 includes: a pressing component 51, which is arranged on the machine tool 100 and is used to press the workpiece to be machined to prevent deformation caused by gravity due to excessive length; a follow-up component 52, which is arranged on the pressing component 51 and is used to rotate together with the workpiece to be machined and can move following the turning tool on the machine tool 100 during machining.

[0049] In this embodiment, through the coordinated action of the pressing component 51 and the follow-up component 52, rigid support and dynamic follow-up of the workpiece to be machined are achieved, thereby preventing the workpiece from deforming due to gravity, ensuring the contact accuracy between the tool and the workpiece during turning and milling machining, and avoiding machining errors and equipment collision risks caused by workpiece bending.

[0050] Embodiment 2 As Figures 11 to 13 shown, the same or corresponding components as those in Embodiment 1 adopt the corresponding reference numerals in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below. The differences between this Embodiment 2 and Embodiment 1 are as follows: The pressing component 51 includes: a lower bottom plate 501, which is arranged on the machine tool 100; an upper cover plate 502, which is arranged on the lower bottom plate 501 through fasteners; an internal gear 503, which is rotatably arranged in the annular groove inside the lower bottom plate 501; a driven gear 504, which is rotatably arranged inside the lower bottom plate 501 and meshes with the internal gear 503; a toothed slide plate 505, which is slidably arranged in the chute of the upper cover plate 502 and meshes with the driven gear 504 for transmission; a first bevel gear 506, which is in transmission connection with one of the driven gears 504; a second bevel gear 507, which meshes with the first bevel gear 506; The sixth motor 508, the output shaft of the sixth motor 508 is drivingly connected to the second bevel gear 507.

[0051] In this embodiment, by providing the pressing assembly 51, the sixth motor 508 drives the second bevel gear 507 to mesh and drive with the first bevel gear 506, and through the gear pair of the driven gear 504 and the internal gear 503, the toothed slide plate 505 is driven to move horizontally in the chute, so as to realize the pressing and fixing of the workpiece to be processed, thereby preventing the workpiece from deforming due to the influence of gravity caused by its excessive length and ensuring the machining accuracy of turning and milling.

[0052] Specifically, the sixth motor 508 is fixedly installed on the top surface of the upper cover plate 502, and its output shaft is connected to the second bevel gear 507 by a key. When the motor is started, the second bevel gear 507 rotates and meshes with the first bevel gear 506 (both of their cone angles are 45°), so that the first bevel gear 506 drives the coaxial driven gear 504 to rotate. The driven gear 504 meshes with the internal gear 503, and the internal gear 503 is rotatably arranged in the annular groove of the lower bottom plate 501. When the internal gear 503 rotates, it drives other driven gears 504 to rotate, and further drives the toothed slide plate 505 to move horizontally in the chute, and the follower assembly 52 on the top surface of the slide plate gradually abuts against the side surface of the workpiece to realize pressing.

[0053] Further, as Figures 13 to 14 shown, the follower assembly 52 includes: A rotating rod 521, the rotating rod 521 is arranged on a bearing inside the toothed slide plate 505, and a chute is provided on the rotating rod 521; A sliding wheel 522, the sliding wheel 522 is slidably arranged on the chute of the rotating rod 521 and rotates synchronously with the rotating rod 521; A second spring 523, the second spring 523 is sleeved on the rotating rod 521 and is used for the sliding wheel 522 to return to its original position when the machining is stopped.

[0054] In this embodiment, through the sliding cooperation between the rotating rod 521 and the sliding wheel 522, and the reset function of the second spring 523, the function that the follower assembly 52 follows the movement of the lathe tool and rotates synchronously with the workpiece to be processed is realized. Furthermore, during turning and milling, the support position is dynamically adjusted to prevent machining errors caused by the bending of the workpiece and avoid collisions between the tool and the workpiece.

[0055] Specifically, the rotating rod 521 is installed in the through hole of the toothed slide plate 505 through a deep groove ball bearing. Its axial chute contacts the outer surface of the rod. When the rod rotates, the frictional force drives the rotating rod 521 to rotate synchronously around the bearing axis; the sliding wheel 522 is embedded in the chute of the rotating rod 521. When the turning tool moves laterally, the cutting edge pushes the sliding wheel 522 to slide in the chute, thus following the turning tool trajectory; the second spring 523 is sleeved on the end of the rotating rod 521. When the machining stops, the spring force pushes the rotating rod 521 to reset, so that the sliding wheel 522 returns to the initial position of the chute.

[0056] Working process When the machining center with the chip removal and cleaning structure is working, the strip-shaped chips generated during machining first pass through the filtering mechanism to separate the cutting fluid, and then are longitudinally cut and segmented by the longitudinal crushing component, and then transversely cut by the transverse crushing component. After that, the ball pressing component presses the crushed chips into balls to reduce viscosity for easy transportation. The conveying mechanism discharges the chip balls through the screw rod. The cleaning mechanism can cover the chip discharge groove and wash the screw rod with high-pressure water. The pressing component of the supporting mechanism presses the long rod through gear transmission. The rotating rod and the sliding wheel of the follow-up component rotate following the workpiece and move with the lathe tool, preventing the rod from deforming due to gravity and ensuring the machining accuracy.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
