Description

Technical Field

[0001] The present invention relates to the technical field of numerically controlled machine tools, and in particular to a drilling and turning compound numerically controlled machine tool. Background Art

[0002] In the field of mechanical processing, CNC machine tools play an important role, capable of achieving high-precision processing of workpieces and meeting the needs of various industrial production.

[0003] To avoid high temperatures and ensure lubrication, coolant is sprayed onto the workpiece during machining. This sprayed coolant falls to the bottom of the machine tool under the influence of gravity. A coolant recovery device is installed underneath the machine tool to collect and reuse this coolant, thus achieving a certain degree of resource recycling and reducing production costs. However, during machining, the cutting of the workpiece generates a large amount of waste chips, which also fall to the bottom of the machine tool under the influence of gravity and mix with the coolant.

[0004] When coolant and waste chips mix, the coolant recovery process becomes complicated and inefficient. First, to ensure coolant purity, waste chips must be filtered out during recovery. In practice, waste chips can clog the filter, preventing smooth coolant recovery. Frequent cleaning or replacement of the filter can increase equipment maintenance workload and affect production continuity.

[0005] To sum up, the existing technology fails to effectively separate waste chips and coolant, resulting in a series of problems in the coolant recovery process, such as difficulty in filtration, easy clogging, high equipment maintenance costs, and reduced production efficiency. The existing technology has not solved the above problems well, so there is an urgent need for a drilling and turning compound CNC machine tool to solve the above problems. Summary of the Invention

[0007] The technical solution of the present invention is as follows: A drilling and turning compound CNC machine tool includes a base, a chuck, a pulley, a circulating belt and an intercepting piece. The chuck is rotatably arranged on the base and is used to clamp the workpiece. The pulleys are rotatably arranged on the base in pairs. The circulating belt is sleeved on the pulley. The circulating belt is located below the chuck and is used to collect coolant and waste chips. There is an angle between the circulating belt and the horizontal plane. The running direction of the circulating belt is toward the upper end of the circulating belt. The intercepting piece is arranged on the circulating belt and has multiple filter holes. There are multiple intercepting pieces.

The chip removal auger rotates in the chip removal channel, and the chip collection box is located next to the base. The chip removal channel is used to communicate with the chip collection box.

[0009] Optionally, it further includes a shift rod, which is used to be set beside the upper end of the circulating belt. The intercepting piece is a rubber piece. The shift rod is located on the moving path of the intercepting piece, and the shift rod is used to shift the intercepting piece.

[0010] Optionally, it also includes a motor and a rotating shaft, the motor is arranged on the base, the rotating shaft is rotatably arranged on the base, the motor is drivingly connected to the rotating shaft, the shift rod is arranged on the circumferential surface of the rotating shaft, and there are multiple shift rods.

[0011] Optionally, a baffle is further included, wherein the baffle is arranged on the base, there are two baffles and they are respectively located on both sides of the circulating belt, and the baffles contact the circulating belt.

[0012] Optionally, a liquid collecting box is further included, which is arranged beside the base and below the lower end of the circulating belt.

[0013] Optionally, it also includes a three-dimensional motion mechanism, a cutterhead, a drill rod and a turning tool. The three-dimensional motion mechanism is arranged on the base, and the cutterhead rotates on the three-dimensional motion mechanism. The cutterhead realizes movement in three-dimensional space with the help of the three-dimensional motion mechanism. The drill rod and the turning tool are both installed on the cutterhead, and the cutterhead is used to switch the tool to be used after rotation.

[0014] Optionally, it also includes a swing rail and an arc-shaped support plate, the swing rail having a first end and a second end, the first end being rotatably arranged relative to the base, the arc-shaped support plate being arranged on the second end, the swing rail having an angle with the horizontal plane, and the swing rail being used to make the arc-shaped support plate concentric with the chuck or cancel concentricity after swinging, and also includes a push plate, the push plate being installed on the tool disc, and the push plate being used to push the workpiece on the arc-shaped support plate toward the chuck.

[0015] Optionally, it also includes a slide, which is slidably arranged on the base, and the slide slides around the center of the chuck. The first end is swingably arranged on the slide, and after the slide slides, it is used to make the first end higher than the second end, or make the second end higher than the first end.

[0017] The working principle and beneficial effects of the present invention are:

[0018] When performing drilling and turning operations, the workpiece to be processed is first mounted on the chuck. The chuck starts to rotate, driving the workpiece to rotate, and the machine tool's tool drills or turns the workpiece. At the same time, the coolant spraying system sprays coolant onto the processing area to cool and lubricate it. The coolant and the waste chips generated by the processing fall together under the action of gravity and fall directly onto the circulating belt located below the chuck. Since the circulating belt is at an angle to the horizontal plane and its running direction is toward the upper end, the coolant flows to the lower end of the circulating belt through the filter holes on the intercepting plate under the action of gravity, and is finally collected by the pre-installed coolant collection device at the lower end of the circulating belt. Since the waste chips cannot pass through the filter holes, as the circulating belt moves toward the upper end, they are continuously pushed to the upper end of the circulating belt by the intercepting plate, and are collected and processed by the corresponding waste chip collection device at the upper end of the circulating belt.

[0019] By designing an inclined circulation belt and combining the ingenious design of intercepting plates and filter holes, efficient separation of coolant and waste chips is achieved, which greatly improves the problem of the traditional technology that the two are difficult to handle. It avoids the situation where waste chips clog the filter device, and there is no need for frequent cleaning or replacement of the filter device, which improves the stability of equipment use and the continuity of production. The coolant and waste chips are quickly separated, and the filtration is completed during the collection process, so that the coolant can be recycled and reused in time, improving processing efficiency.

DETAILED DESCRIPTION

[0028] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive work.

[0029] To simplify the drawings, only portions relevant to the invention are schematically depicted in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one component with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0030] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0031] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0032] Reference Figures 1 to 6, which is the first embodiment of the present invention, proposes a drilling and turning compound CNC machine tool, including a base 1, a chuck 2, a pulley 3, a circulating belt 4 and an intercepting piece 5. The chuck 2 is rotatably arranged on the base 1 for clamping the workpiece, and the pulleys 3 are rotatably arranged on the base 1 in pairs. The circulating belt 4 is sleeved on the pulley 3, and the circulating belt 4 is located below the chuck 2 for collecting coolant and waste chips. The circulating belt 4 has an angle with the horizontal plane, and the running direction of the circulating belt 4 is toward the upper end of the circulating belt 4. The intercepting piece 5 is provided on the circulating belt 4, and the intercepting piece 5 has a plurality of filter holes 7. There are multiple intercepting pieces 5. The intercepting piece 5 is used to transport waste chips to the upper end of the circulating belt 4, and the filter holes 7 are used to allow the coolant to flow to the lower end of the circulating belt 4.

[0033] In this embodiment, during drilling or turning operations, the workpiece to be machined is first mounted on chuck 2. Chuck 2 then begins to rotate, driving the workpiece in rotation. The machine tool's cutting tool then drills or turns the workpiece. Simultaneously, a coolant spray system sprays coolant onto the workpiece, providing cooling and lubrication. The coolant and waste chips generated during machining fall together under the influence of gravity, landing directly on the circulating belt 4 located below chuck 2. Because circulating belt 4 is angled with the horizontal and runs upward, the coolant, under the influence of gravity, flows through the filter holes 7 in interceptor plate 5 toward the lower end of the circulating belt 4, where it is ultimately collected by a pre-installed coolant collection device. Since the waste chips cannot pass through the filter holes 7, they are continuously pushed toward the upper end of the circulating belt 4 by interceptor plate 5 as the circulating belt 4 rotates upward. There, they are collected and processed by a corresponding waste chip collection device.

[0034] By designing an inclined circulation belt 4, combined with the ingenious design of the intercepting piece 5 and the filter hole 7, efficient separation of coolant and waste chips is achieved, which greatly improves the problem of the traditional technology that the two are difficult to handle. The situation of waste chips clogging the filter device is avoided, and there is no need to frequently clean or replace the filter device, which improves the stability of equipment use and the continuity of production. The coolant and waste chips are quickly separated, and the filtration is completed during the collection process, so that the coolant can be recycled and reused in time, thereby improving processing efficiency.

[0035] Furthermore, the base 1 has a chip removal channel 8, which is located below the upper end of the circulating belt 4. It also includes a chip removal auger 9 and a chip collection box 10. The chip removal auger 9 is rotatable in the chip removal channel 8, and the chip collection box 10 is located next to the base 1. The chip removal channel 8 is used to communicate with the chip collection box 10.

[0036] In this embodiment, the interception plate 5 on the circulating belt 4, by virtue of its structure, gradually pushes the waste chips to the upper end of the circulating belt 4. When the waste chips reach the upper edge of the circulating belt 4, they fall into the chip discharge channel 8 directly below under the action of gravity. The spiral blades of the chip discharge auger 9 fit tightly against the inner wall of the chip discharge channel 8. As the chip discharge auger 9 rotates, the waste chips are pushed forward in an orderly manner. The outlet of the chip discharge channel 8 is located above the chip collection box 10, and the waste chips eventually fall into the chip collection box 10, completing the transfer and collection from the processing area to the centralized collection point.

[0037] Automated chip collection reduces downtime due to chip cleaning. Compared to traditional manual chip cleaning, operators do not need to interrupt the machining process to clean chips, achieving online chip cleaning and improving overall production efficiency. Chips can be collected promptly and orderly into the chip box 10, preventing them from being scattered in and around the machine tool. This reduces the risk of wear on key machine tool components such as guide rails and lead screws, helping to extend the service life of the machine tool. The centralized collection of chips by the chip box 10 creates a clean and orderly working environment.

[0038] Furthermore, it also includes a lever 11, which is used to be set beside the upper end of the circulating belt 4. The intercepting piece 5 is a rubber piece. The lever 11 is located on the moving path of the intercepting piece 5. The lever 11 is used to move the intercepting piece 5.

[0039] Furthermore, it also includes a motor 12 and a rotating shaft 13, the motor 12 is arranged on the base 1, the rotating shaft 13 is rotatably arranged on the base 1, the motor 12 is drivingly connected to the rotating shaft 13, the shift rod 11 is arranged on the circumferential surface of the rotating shaft 13, and there are multiple shift rods 11.

[0040] In this embodiment, the power output by motor 12 is transmitted to a drive-connected rotating shaft 13, driving the rotation of the rotating shaft 13. Because multiple levers 11 are located on the circumference of the rotating shaft 13, as the rotating shaft 13 rotates, these levers 11 sequentially traverse a specific path alongside the upper end of the endless belt 4. Simultaneously, driven by pulley 3, the endless belt 4 transports the intercepting plate 5 toward the upper end. When the intercepting plate 5 moves into the rotational path of lever 11, lever 11 contacts the intercepting plate 5. The continuous rotation of lever 11 periodically shifts the intercepting plate 5. Because the intercepting plate 5 is made of rubber and has a certain degree of flexibility, the shifting of lever 11 causes the intercepting plate 5 to undergo a certain degree of elastic deformation and vibration. This deformation and vibration causes any waste chips that may be stuck to the intercepting plate 5 to be subjected to external forces, overcoming their adhesion to the intercepting plate 5 and breaking away from it, falling into the chip removal channel 8 below. In this way, the shifting rod 11 rotates continuously, constantly shifting the intercepting piece 5 passing by, and effectively preventing the waste chips from adhering to and accumulating on the intercepting piece 5.

[0041] The lever 11 periodically moves the rubber interceptor 5, effectively preventing debris from sticking and ensuring stable transfer of debris from the interceptor 5 to the chip removal channel 8, ensuring consistent chip removal. This prevents excessive wear on the interceptor 5 due to chip accumulation, and reduces the risk of damage to the recirculating belt 4 and drive components caused by chip blockage. This stable chip removal eliminates the need for frequent machine shutdowns for chip removal, enabling extended periods of continuous operation.

[0042] Furthermore, it includes a baffle 14 , which is provided on the base 1 . There are two baffles 14 , which are respectively located on both sides of the circulating belt 4 , and the baffles 14 contact the circulating belt 4 .

[0043] In this embodiment, when the coolant and waste chips fall from the processing area to the circulation belt 4, the baffle 14 comes into play. Since there are two baffles 14 and they are respectively arranged on both sides of the circulation belt 4, and the baffles 14 are in close contact with the circulation belt 4, when the coolant flows along the circulation belt 4, the baffle 14 will prevent the coolant from flowing out from both sides of the circulation belt 4, ensuring that the coolant can only flow along the established path of the circulation belt 4 and will not overflow from both sides.

[0044] By preventing the coolant from flowing down the sides of the circulation belt 4, the coolant can flow along the designed path of the circulation belt 4, avoiding unnecessary loss of coolant, ensuring that the coolant can be effectively collected and reused, and improving the utilization rate of the coolant. Preventing the coolant from leaking from the sides of the circulation belt 4 prevents the coolant from spilling on the ground around the machine tool, keeping the working area dry and clean. Ensuring that the coolant is concentrated in the circulation belt 4 is conducive to the smooth separation process of the coolant and waste chips, allowing the coolant to flow downward smoothly through the filter holes 7 on the intercepting plate 5. At the same time, the waste chips can also be transported to the upper end of the circulation belt 4 in an orderly manner under the push of the intercepting plate 5, ensuring the coordinated operation of the entire processing system.

[0045] Furthermore, it also includes a liquid collecting box 15, which is arranged beside the base 1 and below the lower end of the circulating belt 4.

[0046] In this embodiment, during the drilling and turning processing of the machine tool, the coolant and the waste chips fall onto the circulation belt 4 together. The circulation belt 4 separates the coolant from the waste chips by virtue of its own inclined design and the function of the interception plate 5. The coolant flows to the lower end of the circulation belt 4 under the action of gravity through the filter holes 7 on the interception plate 5. The collecting tank 15 is arranged next to the base 1 and is located directly below the lower end of the circulation belt 4. The coolant follows the guidance of the circulation belt 4 and flows continuously into the collecting tank 15. During the entire processing process, the coolant continuously falls from the circulation belt 4 into the collecting tank 15, completing the coolant collection process.

[0047] The arrangement of the collection tank 15 provides a dedicated collection space for the coolant, and its precise location below the lower end of the circulating belt 4 ensures that the coolant can be collected efficiently and accurately. After the coolant is collected in the collection tank 15, it is convenient for subsequent processing and recycling.

[0048] Furthermore, it also includes a three-dimensional motion mechanism 16, a cutter head 17, a drill rod 18 and a turning tool 19. The three-dimensional motion mechanism 16 is arranged on the base 1, and the cutter head 17 is rotatably arranged on the three-dimensional motion mechanism 16. The cutter head 17 is moved in three-dimensional space with the help of the three-dimensional motion mechanism 16. The drill rod 18 and the turning tool 19 are both installed on the cutter head 17. After the cutter head 17 rotates, it is used to switch the tool to be used.

[0049] In this embodiment, the three-dimensional motion mechanism 16 can move the cutter disc 17 to a suitable position according to the processing requirements. The three-dimensional motion mechanism 16 includes a vertical moving frame, a transverse moving frame and a longitudinal moving frame, wherein the vertical moving frame is vertically slidably arranged on the base 1, the transverse moving frame is transversely slidably arranged on the vertical moving frame, the longitudinal moving frame is longitudinally slidably arranged on the transverse moving frame, and the cutter disc 17 is rotatably arranged on the longitudinal moving frame. When drilling operation is required, the cutter disc 17 is driven by the three-dimensional motion mechanism 16 to locate the position on the workpiece where drilling is required. Then the cutter disc 17 rotates to adjust the drill rod 18 to the working position so that it is aligned with the workpiece. The drill rod 18 starts to rotate at high speed, and at the same time, with the cooperation of the three-dimensional motion mechanism 16, it feeds into the inside of the workpiece to complete the drilling operation. When turning processing is required, the cutter disc 17 rotates to switch the turning tool 19 to the working position. Chuck 2 rotates the workpiece, and three-dimensional motion mechanism 16 moves cutterhead 17 and turning tool 19 in three dimensions, according to the desired turning trajectory and dimensions. Throughout the machining process, cutterhead 17 flexibly switches between drill rod 18 and turning tool 19, depending on the machining step. Its rotation allows for rapid switching between different tools to meet diverse machining requirements.

[0050] The drill rod 18 and turning tool 19 are integrated into the cutterhead 17. The tool is switched by rotating the cutterhead 17, enabling the machine tool to conveniently perform two different machining operations: drilling and turning. This eliminates the need for manual tool changes, improving machining convenience. The three-dimensional motion mechanism 16 precisely controls the position of the cutterhead 17 in three dimensions. This, combined with tool switching on the cutterhead 17, ensures precise positioning and movement of the tools during drilling and turning operations, thereby improving machining accuracy and ensuring the dimensional and shape precision of the workpiece.

[0051] Furthermore, it also includes a swing rail 20 and an arc-shaped support plate 21, the swing rail 20 has a first end 22 and a second end 23, the first end 22 is rotatably arranged relative to the base 1, and the arc-shaped support plate 21 is arranged on the second end 23, and there is an angle between the swing rail 20 and the horizontal plane. After the swing rail 20 swings, it is used to make the arc-shaped support plate 21 concentric with the chuck 2 or cancel the concentricity, and also includes a push plate 24, the push plate 24 is installed on the tool disc 17, and the push plate 24 is used to push the workpiece on the arc-shaped support plate 21 toward the chuck 2.

[0052] In this embodiment, when preparing for processing, the bar to be processed is first placed on the first end 22 of the swing rail 20. Due to the angle between the swing rail 20 and the horizontal plane, the bar naturally rolls along the swing rail 20 toward the second end 23 under the action of gravity. When the bar rolls onto the curved support plate 21 at the second end 23, the curved support plate 21 and the bar positioned thereon remain concentric with the chuck 2. Next, the rotation of the cutter disc 17 is activated, and the push plate 24 is switched to the working position by the rotation of the cutter disc 17. The cutter disc 17 drives the push plate 24 to move, which precisely pushes the bar and smoothly pushes it toward the chuck 2. When the bar enters the clamping range of the chuck 2, the chuck 2 locks the bar, completing the bar's positioning and thus completing the entire automatic loading process. After loading is completed, the swing rail 20 can swing around the first end 22, freeing up space near the chuck 2 to facilitate processing.

[0053] The coordinated operation of the swing rail 20, curved support plate 21, and push plate 24 automates the loading process, from bar placement to precise delivery into chuck 2. This significantly reduces manual operations and reduces labor intensity. The design of the swing rail 20 and curved support plate 21 ensures that the bar remains concentric with the chuck 2 before entering. Combined with the precise push of the push plate 24, the bar is accurately positioned once inside.

[0054] The automatic loading process significantly shortens the preparation time for each operation and reduces downtime caused by manual loading. The machine tool can quickly transition from one processing cycle to the next, improving equipment utilization and production efficiency. Compared with traditional manual loading methods or complex automated loading equipment, this design achieves automatic loading through a clever mechanical structure, eliminating the need for operators to enter the machine tool, thereby improving safety.

[0055] Furthermore, it also includes a slide 25, which is slidably arranged on the base 1, and the slide 25 slides around the center of the chuck 2. The first end 22 is swingably arranged on the slide 25. After the slide 25 slides, it is used to make the first end 22 higher than the second end 23, or to make the second end 23 higher than the first end 22.

[0056] In this embodiment, during the loading phase before processing, the swing rail 20 is tilted, with the first end 22 higher than the second end 23. At this point, the operator places the bar to be processed on the first end 22 of the swing rail 20. Under the influence of gravity, the bar rolls smoothly along the inclined swing rail 20 to the curved support plate 21 at the second end 23, facilitating loading. After loading is complete, the swing rail 20 swings out of the way, freeing up space near the chuck 2 for easier processing.

[0057] After processing is complete, the unloading phase begins. First, the second end 23 of the swing rail 20 is swung to the chuck 2. Then, the slide 25 slides on the base 1, so that the second end 23 of the swing rail 20 remains in the same position, the first end 22 is lowered, and the swing rail 20 is tilted so that the second end 23 is higher than the first end 22. Because the sliding path of the slide 25 is concentric with the center of the chuck 2, the curved support plate 21 remains concentric with the center of the chuck 2 throughout the entire sliding process of the slide 25. The chuck 2 then releases the processed workpiece, and under the action of gravity, the workpiece rolls from the curved support plate 21 along the swing rail 20 to the first end 22, making it easier for the operator to collect it.

[0058] By sliding the slide 25 to change the tilt of the swing rail 20, automatic loading of bars and unloading of workpieces are cleverly achieved, significantly improving the efficiency of material loading and unloading during processing. The slide 25 slides about the center of the chuck 2, ensuring that regardless of the tilt of the swing rail 20 during loading and unloading, the curved support plate 21 remains concentric with the center of the chuck 2, ensuring accurate positioning of bars and workpieces during transport.

[0059] Furthermore, it also includes a telescopic member 26, a gear 27 and a rack 28. The two ends of the telescopic member 26 are respectively hinged to the slide 25 and the base 1. The gear 27 is coaxially arranged on the first end 22. The rack 28 is slidably arranged on the slide 25, and the rack 28 is engaged with the gear 27.

[0060] In this embodiment, one end of the telescopic member 26 is hinged to the base 1, and the other end is hinged to the slide 25. The extension or contraction of the telescopic member 26 pushes the slide 25 to slide along a trajectory centered on the center of the chuck 2. Because the rack 28 is meshed with the gear 27 coaxially disposed on the first end 22 of the swing rail 20, the linear movement of the rack 28 can be converted into the circumferential rotation of the gear 27. A screw is rotatably provided on the slide 25, and the rack 28 is threadedly connected to the screw. When the screw drives the rack 28 to move, it can drive the gear 27 to rotate, and the first end 22 of the swing rail 20 rotates about the hinge point with the slide 25, so that the swing rail 20 adjusts the tilt state of the first end 22 and the second end 23.

[0061] The telescopic member 26 is used to drive the slide 25, and the rack 28 and the gear 27 cooperate to drive the first end 22 of the swing rail 20 to rotate. This transmission method can achieve precise control of the position of the slide 25 and the inclination angle of the swing rail 20, which can ensure the accuracy and stability of the loading and unloading process and improve the success rate of loading and unloading.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
