Detailed Implementation

[0015] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0016] High-speed machines are high-speed gear machining tools, such as... Figure 1 The main components include a rotary worktable, a drive spindle housing 33, a fixed tailstock, and a chip removal mechanism. The rotary worktable is used to place the workpiece to be processed, the drive spindle housing 33 is used to install the machining tool, and the fixed tailstock is used to clamp the workpiece to be processed. The workpiece is automatically processed by the machining tool. This application mainly focuses on improving the automatic chip removal device 1 of the machine tool. The following is a description based on a specific embodiment.

[0017] Example 1: This embodiment provides an automatic chip removal device 1 for a high-speed machine, including a frame and a rotary worktable mounted on the frame, and further including: A chip collection tray 11 is arranged around the rotating worktable, and the chip collection tray 11 is provided with a chip discharge slot; The scraper assembly 12 is located inside the chip collection disc 11 and one end is mounted on the rotary worktable. The scraper assembly 12 is used to push the chips from the chip collection disc 11 into the slot. The spiral chip conveyor 13 includes an inlet end and an outlet end. The inlet end is located inside the frame and below the slot of the chip collection tray 11, and the outlet end extends outside the frame. An external chip conveyor is located on one side of the frame, and the receiving end of the external chip conveyor is located below the discharge end of the spiral chip conveyor 13. The spiral chip conveyor 13 is used to send the chips that enter the spiral chip conveyor 13 to the external chip conveyor.

[0018] In this embodiment, the high-speed automatic chip conveying device 1 includes a frame, a rotary table, a chip collection disc 11, a scraper assembly 12, a spiral chip conveyor 13, and an external chip conveyor. The frame provides a stable mounting reference. The rotary table is horizontally mounted above the frame to support workpiece processing. The chip collection disc 11 forms a closed chip collection space around the outer periphery of the rotary table, and its edge is provided with a through slot as a chip discharge channel. The scraper assembly 12 is located inside the chip collection disc 11 and one end is fixedly connected to the rotary table. The spiral chip conveyor 13 is installed inside the frame, with the inlet end facing the bottom of the slot and the outlet end extending outside the frame. The external chip conveyor is located on one side of the frame, with the receiving end located below the outlet end of the spiral chip conveyor 13. During high-speed machining, the rotary table drives the workpiece to rotate simultaneously... The rotating scraper assembly 12 rotates synchronously, causing the processed chips to fall into the chip collection disc 11. The rotating scraper assembly 12 pushes the chips towards the slot, where they fall into the feed end of the spiral chip conveyor 13. The spiral chip conveyor 13 then conveys the chips to the discharge end, finally discharging them into an external chip conveyor, which then delivers them to a designated collection area. This device achieves precise chip collection through the cooperation of the chip collection disc 11 and the scraper assembly 12. The scraper assembly 12, powered by the rotating worktable, requires no additional drive, simplifying the structure and reducing energy consumption. The spiral chip conveyor 13 and the external chip conveyor form a continuous conveying channel, achieving fully automated chip removal throughout the process. This adapts to the pace of high-speed machining, improves chip removal efficiency, reduces manual intervention and equipment failure, and ensures continuous and stable operation of the high-speed machine.

[0019] Example 2: This embodiment provides an automatic chip removal device 1 for a high-speed machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0020] The frame is equipped with a chip collection trough located below the slot of the chip collection disc 11. The bottom of the chip collection trough is equipped with a chip collection funnel 111, and the feed end of the spiral chip conveyor 13 is located below the chip collection funnel 111.

[0021] In this embodiment, a chip collection groove is added directly below the slot of the chip collection disc 11 inside the frame. The inner sidewall of the groove slopes downwards and converges to the bottom. A chip collection funnel 111 with a large opening at the top and a small opening at the bottom is fixedly installed at the lowest point of the bottom of the chip collection groove. The upper end of the funnel is in contact with the bottom of the chip collection groove, and the lower end is directly opposite the feed end of the spiral chip conveyor 13. After the chips in the chip collection disc 11 fall into the chip collection groove through the slot, they slide and converge along the inclined sidewall towards the chip collection funnel 111. Then, they are guided by the converging structure of the funnel and fall vertically into the feed end of the spiral chip conveyor 13. This design achieves initial aggregation of chips through the chip collection groove, preventing them from scattering and accumulating inside the frame. The chip collection funnel 111 enhances the guiding effect, ensuring that all chips enter the spiral chip conveyor 13, improving the collection and utilization rate and avoiding leakage. At the same time, the two work together to buffer the chips, reduce the impact on the feed end of the spiral chip conveyor 13, extend the service life of the components, and improve the stability of chip discharge.

[0022] Example 3: This embodiment provides an automatic chip removal device 1 for a high-speed machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0023] The scraper assembly 12 includes a scraper 121 and a mounting rod 122 connected to each other. The scraper 121 is located inside the chip collection disc 11, and the mounting rod 122 is connected to the rotary table.

[0024] In this embodiment, the scraping assembly 12 consists of a scraper 121 and a mounting rod 122. One end of the mounting rod 122 is fixedly connected to the rotary table. One end of the flat scraper 121 is vertically fixed to the other end of the mounting rod 122. The bottom of the scraper 121 is in close contact with the inner bottom surface of the chip collection disk 11, and its width matches the radial width of the chip collection disk 11 to cover the entire chip collection area. When the rotary table rotates, it drives the mounting rod 122 to make a circular motion, which in turn drives the scraper 121 to slide along the inner bottom surface of the chip collection disk 11. The close contact design of the bottom of the scraper 121 prevents the chips from slipping away from the bottom.

[0025] Example 4: This embodiment provides an automatic chip removal device 1 for a high-speed machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0026] The spiral chip conveyor 13 includes: The housing 131 is connected to the frame, and a conveying channel is formed inside the housing 131; The screw conveyor rod 132 is installed inside the conveying channel; A drive motor 133 is mounted on the housing 131 and is used to drive the screw conveyor 132 to rotate.

[0027] In this embodiment, the spiral chip conveyor 13 includes a housing 131, a spiral conveying rod 132, and a drive motor 133. The housing 131 has a cylindrical conveying channel extending along its length, with an inlet and an outlet at its two ends. The spiral conveying rod 132 is coaxially mounted within the conveying channel, with its two ends rotatably engaged with the end walls of the housing 131 via bearings. The spiral blades are evenly distributed along the rod, and their edges are tightly fitted against the inner wall of the channel. The drive motor 133 is bolted to the outer side of one end of the housing 131, and its output shaft is coaxially connected to one end of the spiral conveying rod 132 via a transmission structure. Chips are collected from the housing... After the chip funnel 111 falls into the feed end of the spiral chip conveyor 13, the drive motor 133 drives the spiral conveyor 132 to rotate in the conveying channel. The spiral blades generate axial pushing force, continuously conveying the chips along the channel to the discharge end and discharging them to the external chip conveyor. The adaptive design of the spiral conveyor 132 and the channel achieves seamless conveying and high chip removal efficiency, meeting the needs of high-speed machines for conveying large amounts of chips. The drive motor 133 provides stable power to ensure uniform chip removal speed, precisely matching the processing rhythm of high-speed machines. The bearing connection reduces rotational friction, lowers energy consumption and component wear, and extends the service life of the equipment.

[0028] Example 5: This embodiment provides an automatic chip removal device 1 for a high-speed machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0029] The external chip conveyor includes a receiving section, a lifting section and a discharging section connected in sequence. The receiving section is located below the discharging end of the spiral chip conveyor 13.

[0030] In this embodiment, the external chip conveyor is divided into a receiving section, a lifting section, and a discharging section connected in sequence. The three sections are integrally formed or bolted together to form a continuous conveying path. The upper surface of the horizontally arranged receiving section is open and directly opposite the discharge direction of the spiral chip conveyor 13. The upper part of the receiving section is directly above the discharge end of the spiral chip conveyor 13. The lower end of the inclined upward lifting section is connected to the receiving section, and the upper end is connected to the discharging section. The horizontal discharging section extends to the designated collection area and has a discharge port at the end. After the chips discharged by the spiral chip conveyor 13 fall into the receiving section, they are conveyed to the connection of the lifting section. The traction force generated by the internal structure of the lifting section is used to convey the chips upward along the inclined path, and then to the discharging section. Finally, the chips are discharged into the collection container through the discharge port. The precise docking between the receiving section and the spiral chip conveyor 13 ensures that no chips are missed. The inclined design of the lifting section enables the vertical height of the chips to be raised, meeting the needs of different collection areas and increasing installation flexibility. The three-section integrated structure ensures the continuity of the conveying path, making the chip conveying smooth and without jamming.

[0031] Example 6: This embodiment provides an automatic chip removal device 1 for a high-speed machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0032] A liquid collection tank 141 is provided on one side of the receiving section. A partition 142 is provided between the receiving section and the liquid collection tank 141. The partition 142 is provided with multiple filter holes. The receiving section and the liquid collection tank 141 are connected through the filter holes. A liquid pump for pumping liquid from the liquid collection tank 141 is provided on the liquid collection tank 141.

[0033] In this embodiment, a vertical partition 142 is provided between the receiving section and the collection tank 141. The height of the partition 142 is the same as the side wall of the receiving section. One end of the partition 142 is connected to the end side wall of the receiving section, and the other end extends to the inner side wall of the collection tank 141. Multiple through-filter holes are evenly distributed on the partition 142 to connect the receiving section with the inside of the collection tank 141. A liquid pump is installed on the collection tank 141. The input end is connected to the inside of the collection tank 141, and the output end can be connected to the cutting fluid recovery pipe or storage container. The debris mixed with cutting fluid falls into the receiving section. Subsequently, the debris moves with the conveying structure, and the cutting fluid seeps into the collection tank 141 through the filter holes under the action of gravity, achieving initial separation of the two. The cutting fluid accumulated in the collection tank 141 can be extracted and recycled by the pump. This structure achieves efficient separation of debris and cutting fluid through the filter holes, avoiding resource waste and environmental pollution. The collection tank 141 realizes centralized collection of cutting fluid, and the pump ensures rapid discharge and recycling, improving resource utilization and reducing production costs. The dryness of the separated debris is improved, which is convenient for subsequent centralized processing and recycling.

[0034] Example 7: This embodiment provides an automatic chip removal device 1 for a high-speed machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0035] The external chip conveyor can be any one of the following: chain plate chip conveyor, scraper chip conveyor, or magnetic chip conveyor.

[0036] In this embodiment, the external chip conveyor can be selected from existing chain plate type, scraper type or magnetic chip conveyor that can be purchased externally. The chain plate type chip conveyor is equipped with an annular chain inside, and scrapers 121 that are evenly distributed and perpendicular to the direction of movement are fixedly installed on the chain. The scraper type chip conveyor is equipped with a conveying groove and a sliding scraper 121 that is attached to the inner wall of the groove. The magnetic chip conveyor is equipped with a magnetic roller and a conveyor belt that is adsorbed on the surface of the roller.

[0037] All three types have a three-section structure consisting of a receiving section, a lifting section, and a discharge section, and the connection method of the three sections is consistent with the assembly position. When using a chain plate chip conveyor, the motor drives the chain to circulate, which drives the scraper 121 to receive the chips and convey them through the lifting section to the discharge section for discharge. When using a scraper chip conveyor, the drive mechanism drives the scraper 121 to slide back and forth in the conveying trough, pushing the chips through the lifting section to the discharge section for discharge. When using a magnetic chip conveyor, the magnetic roller rotates to drive the conveyor belt to move. Metal chips are attracted to the conveyor belt under the action of magnetic force. After moving with the conveyor belt to the lifting section and leaving the magnetic area, they fall to the discharge section for discharge under the action of gravity.

[0038] Multiple types of options allow the device to adapt to metal chips of different shapes and materials. The chain plate type is suitable for larger and irregularly shaped chips, the scraper type is suitable for small chips, and the magnetic chip conveyor is suitable for magnetic metal chips. All types of chip conveyors can deliver chips stably and efficiently, meeting the needs of different high-speed machining scenarios and improving the versatility and practicality of the device.
