Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, and in particular to a chip-rolling device for a CNC lathe used in machining. Background Technology

[0002] A CNC lathe for machining is a machine tool controlled by a CNC system for turning operations. It is mainly used for cutting the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc-shaped parts. It can also perform grooving, drilling, reaming, boring, and other operations. The chip removal equipment for CNC lathes is a key auxiliary device for CNC machine tools. Its main function is to quickly remove the chips generated during the machining process from the machining area, while separating the chips from the cutting fluid, ensuring the machining efficiency and accuracy of the machine tool. The chip removal equipment uses mechanical transmission or fluid power to transport the machining waste from the working area to the collection device, ensuring the cleanliness and safety of the machining environment.

[0003] Existing chip-rolling equipment struggles to adjust the guide angle of the collection port according to different chip shapes during chip rolling. Fixing the collection port easily leads to chip accumulation or blockage. Furthermore, when chips generated from different processes are directly discharged through the chip conveyor, chip entanglement can easily occur, clogging the conveyor's channels. Moreover, when faced with chips of varying weights and discharge speeds, it is difficult to quickly adjust the conveying speed according to the chip conditions, resulting in a mismatch between the conveying speed and the machine tool's cutting speed. This leads to chip accumulation and reduced production efficiency. Therefore, this application provides a chip-rolling device for CNC lathes used in machining to meet these needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a chip removal device for CNC lathes used in machining to solve the problems of existing collection port guide angle being fixed, unable to adapt to chips of different shapes, easily causing accumulation or blockage, and chip conveyor directly handling chips of different processes, which is prone to entanglement and blockage of the channel, and the conveying speed adjustment is lagging behind, making it difficult to match the machine tool cutting speed and chip weight changes, resulting in chip accumulation and affecting efficiency.

[0008] Optionally, the forming extrusion assembly includes a frame, which is installed on the inner walls of both ends of the machine tool body. A first collection groove is installed on the top of the frame, which is located at the bottom of the chuck and the tool holder. A second collection groove is installed at the bottom of the first collection groove, which is located inside the frame.

[0009] Optionally, a guide wedge is installed on the inner wall of one end of the frame, a weighing platform is installed on the inner wall of the other end of the frame, an induction weighing plate is installed on the top of the weighing platform, and a first hydraulic cylinder is installed at one end of the top of the weighing platform.

[0010] Optionally, a first push plate is installed at the output end of the first hydraulic cylinder, a second hydraulic cylinder is provided above the guide wedge, a second push plate is installed at the output end of the second hydraulic cylinder, the second push plate is slidably connected to the surface of the guide wedge, and two support plates are installed at the bottom of the second collection tank.

[0011] Optionally, the inner walls of the two support plates are rotatably connected by torsion spring rotating columns, and water seepage plates are installed at both ends of the torsion spring rotating columns. A protruding plug is installed on one end surface of the water seepage plate, and two sets of elastic columns are installed at the bottom of one end of the second collection tank. The two sets of elastic columns are positioned above the protruding plug.

[0012] Optionally, the tension adjustment assembly includes a cylinder, which is installed at one end of the chip conveyor frame. A piston sleeve is installed at the output end of the cylinder, and a round shaft is inserted into the inside of the piston sleeve. A rotating base is installed at one end of the round shaft, and the rotating base is located inside the protective cover.

[0013] Optionally, a sleeve is fitted onto the surface of the circular shaft, and multiple mounting plates are installed at the ends of the sleeve. The multiple mounting plates are distributed around the sleeve, and multiple sets of connecting plates are rotatably connected to the surface of the mounting plates.

[0014] Optionally, one end of the multiple sets of connecting plates is rotatably connected to multiple sliding plates, one end of the multiple sliding plates is slidably connected to a slide groove bracket, the slide groove bracket is installed at the end of the rotating base, multiple drive shafts are installed at the ends of the multiple sliding plates, transmission belts are sleeved on the surfaces of the multiple drive shafts, and arc-shaped drive plates are installed at the ends of the sliding plates.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting up a flow guiding component and adjusting the rotary knob to drive the threaded rod to extend and retract, the tilt angle of the guide plate is adjusted. This allows the shavings collection port to adapt to the flow requirements of shavings of different shapes, such as ribbons and spirals, reducing the probability of accumulation and blockage due to shape differences and improving the multi-angle adaptability of the collection port. Simultaneously, when shavings are discharged through the guide plate, they work in conjunction with the variable frequency fan under the tilted base to accelerate shavings discharge, reducing the risk of collection port blockage. Furthermore, the dynamic guidance of the guide plate can improve the throughput of shavings of different shapes and reduce the number of manual interventions. By setting up a forming extrusion assembly and utilizing the dual collection troughs on the frame for graded processing, the first collection trough guides the shavings, while the second collection trough intercepts the flowing shavings through the rectangular frame at the bottom and the water-permeable tray, forcibly shaping irregularly shaped shavings and regularizing them, reducing the risk of entanglement caused by direct discharge. Subsequently, when the water-permeable tray reaches the critical weight limit, it begins to flip to achieve dynamic unloading, avoiding manual intervention and separating the cutting fluid. Then, the torsion spring pull flips the water-permeable tray back to its original position to continue the interception operation. At the same time, the secondary extrusion of the combination of the guide wedge and the push plate increases the density of the shavings, initially shaping them into regular shapes, improving the throughput of the chip conveyor channel, and reducing the risk of blockage.

[0016] By setting up a tension adjustment component, the weighbridge can monitor the weight of the shavings in real time. Combined with the dynamic adjustment of the conveyor belt tension by the control center, the circumference of the drive belt can be adjusted, and the drive speed of the motor can be adjusted to quickly match the chip removal speed with the cutting speed, thereby improving transportation efficiency. At the same time, the cylinder-driven piston sleeve shaft drives the arc-shaped drive plate to extend and retract, thereby adjusting the conveyor belt tension and effectively meeting the transportation needs of shavings with different densities. The expansion and contraction of the arc-shaped drive plate ensures that the conveyor belt always maintains optimal tension, reducing downtime caused by shavings jamming. Furthermore, by changing the tension of the drive motor drive belt, the load on the drive motor is made more even, extending the service life of the drive motor and reducing the occurrence of overload.

[0026] like Figures 1 to 12As shown, an embodiment of the present invention provides a chip removal device for a CNC lathe used in machining, including a machine tool base 1, a machine tool body 2 mounted on the top of the machine tool base 1, a control center 3 mounted on the surface of the machine tool body 2, a chuck 4 mounted on the inner wall of the machine tool body 2, a tool post 5 slidably connected inside the machine tool body 2, a chip removal frame 9 provided at the bottom of the machine tool body 2, a drive motor 10 mounted on the top of the chip removal frame 9, a transmission belt 17 sleeved on the output end of the drive motor 10, a protective cover 11 mounted on the end of the drive motor 10, a bellows 12 mounted on one end of the protective cover 11, a conveyor belt 14 mounted inside the chip removal frame 9, and the chip removal frame 9... A weighing scale 15 is installed on the inner wall, a chip collection and transfer vehicle 13 is set below the end of the conveyor belt 14, and a guide groove 16 is installed on the top of one end of the chip conveyor frame 9; a guide flow assembly 6 is installed on the inner wall of the machine tool body 2, which is used to adjust the guide angle according to different chip rolls; a forming and extruding assembly 7 is set above the conveyor belt 14, which is used to compact and shape the chip rolls; a tension adjustment assembly 8 is installed on the inner wall of the conveyor belt 14, which is used to adjust the tension of the conveyor belt 14; the guide flow assembly 6 is installed above the forming and extruding assembly 7, and the forming and extruding assembly 7 is installed at one end of the tension adjustment assembly 8.

[0027] As an implementation method in this embodiment, such as Figures 3 to 5As shown, the guiding flow assembly 6 includes an inclined base 61, which is installed on the top of the inner wall of the machine tool body 2. Multiple fans 62 are installed inside the inclined base 61. A rotating rod 63 is rotatably mounted below the inclined base 61. A guide plate 64 is installed at the end of the rotating rod 63. A rotating sleeve 65 is rotatably connected to the end of the guide plate 64. A threaded rod 66 is rotatably connected inside the rotating sleeve 65. Bolts 67 are threaded onto the surface of the threaded rod 66. Rotating cylinders 68 are installed at both ends of the bolts 67 and are rotatably connected to the machine tool body. Springs 610 are installed on both ends of the guide plate 64 on the inner wall of the machine tool body 2. The springs 610 are connected to the inner wall of the machine tool body 2. A knob 69 is provided at the end of the threaded rod 66. When the workpiece is being cut, the guide flow assembly 6 starts to operate. At this time, the threaded rod 66 on the machine tool body 2 is rotated by rotating the knob 69. When the threaded rod 66 rotates, it is extended at one end of the machine tool body 2 by the action of the bolt 67. When the threaded rod 66 extends, the rotating sleeve 65 connected to the end of the threaded rod 66 is pushed and begins to move. The movement of sleeve 65 causes the guide plate 64, which is rotatably connected to both ends of the rotating sleeve 65, to rotate around the rotating rod 63 mounted on the surface of the machine tool body 2. At this time, the flipping angle of the guide plate 64 is adjusted according to the shape of the corresponding shredded material to maintain the smooth conveying of the shredded material. When the guide plate 64 flips, the rotating cylinders 68 installed at both ends of the bolt 67 drive the bolt 67 to flip in accordance with the tilt angle of the threaded rod 66. Then, after the shredded material falls onto the guide plate 64, it continues to move towards the collection port. At this time, when the shredded material moves towards the collection port, the tilting base 61... Multiple fans 62 installed in the unit start to drive, and the generated wind force acts on the surface of the guide plate 64, which accelerates the flow of the shavings on the surface of the guide plate 64 to the collection port. This avoids the accumulation caused by the entanglement of shavings of different shapes when the flow of shavings increases, which would slow down the flow speed and cause blockage. At the same time, the flipping of the guide plate 64 also causes the spring 610 installed at the bottom to stretch. When shavings fall onto the guide plate 64, the spring 610 will generate a slight elastic force to react on the surface of the guide plate 64, further preventing the accumulation of shavings.

[0028] As an implementation method in this embodiment, such as Figures 4 to 8As shown, the forming and extrusion assembly 7 includes a frame 71, which is installed on the inner walls of both ends of the machine tool body 2. A first collection groove 72 is installed on the top of the frame 71, and the first collection groove 72 is located at the bottom of the chuck 4 and the tool holder 5. A second collection groove 73 is installed at the bottom of the first collection groove 72 and is located inside the frame 71. A guide wedge 74 is installed on the inner wall of one end of the frame 71, and a weighing platform 75 is installed on the inner wall of the other end of the frame 71. An induction weighing plate 76 is installed on the top of the weighing platform 75. A first hydraulic cylinder 77 is installed at one end of the top of the weighing platform 75, and a first push plate 78 is installed at the output end of the first hydraulic cylinder 77. A guide wedge 78 is installed above the guide wedge 74. A second hydraulic cylinder 79 is provided, and a second push plate 710 is installed at the output end of the second hydraulic cylinder 79. The second push plate 710 is slidably connected to the surface of the guide wedge block 74. Two support plates 711 are installed at the bottom of the second collection tank 73. A torsion spring rotating column 712 is rotatably connected to the inner wall of the two support plates 711. Water seepage support plates 713 are installed at both ends of the torsion spring rotating column 712. A protruding plug 714 is installed on one end surface of the water seepage support plate 713. Two sets of elastic columns 715 are installed at the bottom of one end of the second collection tank 73. The two sets of elastic columns 715 are positioned above the protruding plug 714. When the shavings are guided through the first collection tank 72 installed on the top of the frame 71 on the inner wall of the machine tool body 2, they are then rolled... The chips continue to flow into the second collection tank 73. As the chips fall into the second collection tank 73, they gradually flow towards the bottom opening of the second collection tank 73. At this time, the slowly flowing chips begin to enter the rectangular opening of the second collection tank 73. Then, the water-permeable plate 713 installed on the bottom support plate 711 of the second collection tank 73 begins to intercept the chips. At the same time, the cutting fluid continues to flow downward through the holes in the water-permeable plate 713. Then, when the weight of the chips on the water-permeable plate 713 reaches the elastic critical value of the elastic column 715 locking the protruding plug 714 and the torsion critical value of the torsion spring rotating column 712, the water-permeable plate 713 begins to rotate around the torsion spring rotating column 712. At this point, the initially accumulated and shaped shavings begin to fall downwards onto the induction weighing plate 76 mounted on the bottom of the weighing platform 75. Upon receiving a feedback signal from the induction weighing plate 76, the first hydraulic cylinder 77 drives the first push plate 78 mounted on the output end to push the shavings on the induction weighing plate 76. The first push plate 78 pushes the shavings, causing them to fall into the space formed between the weighing platform 75 and the guide wedge 74. Then, the second hydraulic cylinder 79 starts operating, driving the second push plate 710 at the output end to push the shavings. At this point, the shavings, which are compressed again, fall from the bottom opening formed between the weighing platform 75 and the guide wedge 74 into the guide groove 16.

[0029] As an implementation method in this embodiment, such as Figures 10 to 12As shown, the tension adjustment assembly 8 includes a cylinder 81, which is installed at one end of the chip conveyor frame 9. A piston sleeve 82 is installed at the output end of the cylinder 81. A round shaft 83 is inserted into the piston sleeve 82. A rotating base 810 is installed at one end of the round shaft 83, which is located inside the protective cover 11. A sleeve 84 is fitted onto the surface of the round shaft 83. Multiple mounting plates 85 are installed at the end of the sleeve 84, and the multiple mounting plates 85 are distributed around the sleeve 84. Multiple sets of connecting plates 86 are rotatably connected to the surface of the mounting plates 85. One end of 86 is rotatably connected to multiple sliding plates 87. One end of each sliding plate 87 is slidably connected to a slide rail bracket 89, which is mounted at the end of the rotating base 810. Multiple drive shafts 88 are mounted at the ends of the sliding plates 87, and transmission belts 17 are sleeved on the surfaces of the drive shafts 88. An arc-shaped drive plate 811 is mounted at the end of each sliding plate 87. When the drive cylinder 81 starts, the cylinder 81 drives the output end to move. As the output end of the cylinder 81 moves, the piston sleeve shaft 82 mounted at the output end moves synchronously. Then the piston sleeve... Shaft 82 continues to move around the surface of the inner circular shaft 83, and then contacts the sleeve 84 fitted onto the surface of the circular shaft 83, pushing it to one end. At this time, the movement of the sleeve 84 causes the mounting plate 85 to move synchronously, and the movement of the mounting plate 85 causes the connecting plate 86 to move along with the sliding plate 87. Due to the action of the sliding groove bracket 89 installed at the end of the sliding plate 87, when the connecting plate 86 moves the sliding plate 87, the sliding plate 87 is limited by the sliding groove bracket 89, so the sliding plate 87 moves within the groove. The sliding plate 87 slides on the bracket 89. When the sliding plate 87 slides on the groove bracket 89 installed at the end of the rotating base 810, the drive shaft 88 installed at the end of the sliding plate 87 moves synchronously. At this time, the circumferential size formed by multiple drive shafts 88 changes, and the transmission belt 17 sleeved on the drive shaft 88 also changes accordingly. At this time, the movement of the sliding plate 87 causes the arc-shaped drive plate 811 installed at one end of the sliding plate 87 to move synchronously in all directions, and then the conveyor belt 14 connected to the surface of the arc-shaped drive plate 811 begins to expand.

[0030] The working principle of the technical solution provided by this invention is as follows: When using this device, first clean the inside of the machine tool body 2 to remove the original chips and maintain a clean working environment. Then, push the chip conveyor frame 9 into the machine tool base frame 1, push the chip collection and transfer cart 13 under the chip conveyor frame 9, fix the workpiece on the chuck 4, and then adjust the tool holder 5 to cut the workpiece on the chuck 4 after setting the parameter data through the control center 3.

[0031] When the workpiece is being cut, the guide flow assembly 6 starts operating. At this time, the threaded rod 66 on the machine tool body 2 is rotated by rotating the knob 69. When the threaded rod 66 rotates, it extends at one end of the machine tool body 2 under the action of the bolt 67. When the threaded rod 66 extends, the rotating sleeve 65 rotatably connected to the end of the threaded rod 66 is pushed and begins to move. The movement of the rotating sleeve 65 causes the guide plate 64 rotatably connected to both ends of the rotating sleeve 65 to rotate around the rotating rod 63 installed on the surface of the machine tool body 2. At this time, the flip angle of the guide plate 64 is adjusted according to the shape of the corresponding chip to maintain the smooth conveying of the chip. When the guide plate 64 flips, the rotating cylinders 68 installed at both ends of the bolt 67 drive the bolt 67 to follow the threaded rod. The tilt angle of 66 is reversed, and the shavings fall onto the guide plate 64 and continue to move towards the collection port. At this time, as the shavings move towards the collection port, the multiple fans 62 installed at the bottom of the tilt base 61 are driven, and the generated wind force acts on the surface of the guide plate 64, causing the shavings on the surface of the guide plate 64 to flow faster to the collection port. This avoids the accumulation caused by the entanglement of shavings of different shapes when the shavings flow rate increases, which would slow down the flow speed and cause blockage. At the same time, the flipping of the guide plate 64 also causes the spring 610 installed at the bottom to be stretched. When the shavings fall onto the guide plate 64, the spring 610 will generate a weak elastic force to react on the surface of the guide plate 64, further preventing the accumulation of shavings.

[0032] When the chips flow through the guide plate 64 to the collection port, the forming and extrusion assembly 7 starts operating. At this time, the chips are guided through the first collection groove 72 on the top of the frame 71 installed on the inner wall of the machine tool body 2, and then continue to flow into the second collection groove 73. When the chips fall into the second collection groove 73, they flow towards the bottom opening of the second collection groove 73 little by little. At this time, the slowly flowing chips begin to enter the rectangular opening of the second collection groove 73, and then the water-permeable plate 713 installed on the bottom support plate 711 of the second collection groove 73 begins to intercept the chips. At the same time, the cutting fluid continues to flow downward through the holes in the water-permeable plate 713. Then, when the weight of the chips on the water-permeable plate 713 reaches the elastic critical value of the elastic column 715 locking the protruding plug 714 and the torque critical value of the torsion spring rotating column 712, the water-permeable plate 713 begins to rotate around the torsion spring rotating column 712. At this time, the initial accumulation and shaping... The shavings begin to fall downwards onto the induction weighing plate 76 mounted on the bottom of the weighing platform 75. Upon receiving a feedback signal from the induction weighing plate 76, the first hydraulic cylinder 77 drives the first push plate 78 mounted on its output end to push the shavings onto the induction weighing plate 76. The first push plate 78 pushes the shavings, causing them to fall into the space between the weighing platform 75 and the guide wedge 74. Then, the second hydraulic cylinder 79 starts operating, driving the second push plate 710 at its output end to push the shavings. The shavings, now compressed again, fall from the bottom opening between the weighing platform 75 and the guide wedge 74 into the guide groove 16, and then move onto the conveyor belt 14. The initially formed shavings continue to be conveyed on the chip conveyor frame 9 via the conveyor belt 14. When the shavings pass the weighing scale 15 at the bottom of the conveyor belt 14, the weight of the formed shavings is obtained, and the data is transmitted to the control center 3.

[0033] After the data from the weighbridge 15 is transmitted to the control center 3, the tension adjustment component 8 is activated based on the weight and speed of the shavings. At this time, the drive cylinder 81 starts, driving the output end to move. As the output end of the cylinder 81 moves, the piston sleeve 82 installed at the output end moves synchronously. Then, the piston sleeve 82 continues to move around the surface of the inner round shaft 83, and then contacts the sleeve 84 fitted onto the surface of the round shaft 83, pushing it to one end. The movement of the sleeve 84 causes the mounting plate 85 to move synchronously, and the movement of the mounting plate 85 causes the connecting plate 86 to move along with the sliding plate 87. Due to the action of the sliding groove bracket 89 installed at the end of the sliding plate 87, when the connecting plate 86 moves the sliding plate 87, the sliding plate 87 is limited by the sliding groove bracket 89, so the sliding... The sliding plate 87 slides on the slide bracket 89. When the sliding plate 87 slides on the slide bracket 89 installed at the end of the rotating base 810, the drive shaft 88 installed at the end of the sliding plate 87 moves synchronously. At this time, the circumference of the circle formed by multiple sets of drive shafts 88 changes, and the transmission belt 17 sleeved on the drive shaft 88 also changes accordingly. At this time, the movement of the sliding plate 87 causes the arc-shaped drive plate 811 installed at one end of the sliding plate 87 to move synchronously in all directions. Then, the conveyor belt 14 connected to the surface of the arc-shaped drive plate 811 begins to expand. Subsequently, the tension of the conveyor belt 14 is adjusted, and the conveying speed is increased. During the tension adjustment process, the air box 12 installed on the protective cover 11 at one end of the drive motor 10 continuously provides airflow to the transmission belt 17 and other parts to achieve the effect of reducing temperature.
