Description

Technical Field

[0001] The invention relates to the technical field of flange processing, in particular to processing equipment for end face gear flanges. Background Art

[0002] The end face serration flange connects the two end faces through the engagement of gears. It does not require additional sealing gaskets and can transmit greater torque and moment. Due to the special connection method, the end face serration flange can be used to connect large-diameter and high-pressure pipes and containers.

[0003] During the processing of the end face tooth flange, it is necessary to process bolt holes on the flange disc to facilitate the fixation and connection of bolts or nuts, and process the flange hole in the middle of the flange to ensure the accuracy and adaptability of the hole.

[0004] Currently, the most common processing equipment is to use a three-jaw chuck to fix the flange, and then use a drill, a turning tool, and a boring tool to process the flange's bolt holes, flange outer wall, and flange holes respectively.

[0005] When traditional equipment switches between processes such as turning, boring, and drilling, it is usually necessary to completely stop the spindle rotation, replace the tool or tooling, and then restart. The start-stop cycle consumes a lot of production time. Repeated starts and stops can easily cause cumulative errors in spindle thermal deformation, and the repeatable positioning accuracy of the workpiece is difficult to ensure. Frequent starts and stops increase equipment vibration, affecting the quality of the processed surface. There is a lack of effective and immediate means to remove debris adhered to the flange surface by high temperature, and it relies on manual cleaning at a later stage.

[0006] In view of this, we propose a processing equipment for end face tooth flange. Summary of the Invention

[0007] The purpose of the present invention is to provide a processing device for an end face gear flange to solve the problems of process switching, debris protection and cleaning, debris recovery and workpiece unloading proposed in the above background technology. To achieve the above purpose, the present invention provides the following technical solutions: a processing device for an end face gear flange, comprising a base, a three-jaw chuck driven to rotate by a rotary motor is provided on the base, the end face gear flange is fixedly mounted on the three-jaw chuck, a turning tool for turning the end face gear flange is provided on one side of the base, a lifting frame is fixedly provided on the base, and a movable table is movably provided on the lifting frame, a circular table is rotatably provided on the side of the movable table, and a plurality of drill bits driven by a drilling motor are annularly provided on the circular table.

[0008] A transmission rod is rotatably provided on the side surface of the movable platform, and gears are provided at both ends of the transmission rod. The outer ring of the circular platform is provided with an upper gear ring that meshes with the upper gear, and the outer ring of the three-jaw chuck is provided with a lower gear ring. When the movable platform moves downward, the lower gear meshes with the lower gear ring.

[0009] A movable boring tool is provided on the upper side of the movable platform.

[0010] Preferably, a strip brush is fixedly provided at the bottom of the frustum, and the strip brush is configured as a U-shaped structure surrounding the drill bit, and the bottom of the strip brush is configured as a bell mouth inclined outward.

[0011] Preferably, a groove is provided on the base, and a ring frame is rotatably arranged in the groove, a flip motor is fixedly arranged on the side of the base, and the rotating shaft of the flip motor is connected to the ring frame, and the three-jaw chuck is rotatably arranged in the ring frame.

[0012] The rotating motor is fixedly mounted on the ring frame, and a through opening for collecting machining debris is provided at the bottom of the groove.

[0013] Preferably, one side of the base is provided with an inclined opening for assisting the end face tooth flange to slide out of the three-jaw chuck.

[0014] Preferably, the three-jaw chuck includes an annular fixed plate, and three calipers are slidably provided on the fixed plate, and a control ring is rotatably provided on the bottom of the fixed plate for driving the displacement of the calipers using spiral patterns.

[0015] Preferably, a track corresponding to the drilling motor is opened on the circular table, and a slide is slidably connected in the track. The drilling motor is fixedly installed on the slide. An adjusting bolt is threadedly connected to the track, and the adjusting bolt is rotatably connected to the slide. When the adjusting bolt rotates, the slide, the drilling motor and the drill bit are pushed to adjust their positions.

[0016] Preferably, the lifting frame is provided with a laser locator for detecting the vertical displacement of the moving platform in real time and linking with the control system.

[0017] Preferably, a cyclone separator is connected below the debris passage.

[0018] A processing device for an end face gear flange comprises the following steps: S1. Place the end face gear flange on the three-jaw chuck and control the three-jaw chuck to shrink and clamp the flange.

[0019] S2. The rotating motor drives the three-jaw chuck and flange to rotate at a constant speed. The turning tool is fed radially to complete the turning of the flange end face. After the turning tool is retracted, the lifting frame drives the moving table to move downward, and the boring tool enters the rotating flange to perform fine processing on its inner wall. During this process, the lower gear of the transmission rod engages with the lower gear ring, and then the upper gear drives the circular table and the three-jaw chuck to rotate synchronously, so that the drill bit and flange positions remain synchronized.

[0020] S3. When the movable table moves downward, the strip brush contacts the three-jaw chuck and deflects outward along the bell mouth, thereby separating the drilling area without contacting the drill bit. After the drill bit is pulled out, the round table continues to drive the strip brush to rotate and brush the flange surface.

[0021] S4. After the processing is completed, the drill bit and boring tool are reset, and the flip motor drives the ring frame to flip so that the flange flips down into the groove. All the debris on the three-jaw chuck and the flange falls into the groove. The ring frame continues to flip and tilt until it is aligned with the inclined mouth. The caliper lock is released, and the flange automatically slides out along the inclined mouth.

[0022] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, a rotating motor drives the three-jaw chuck and flange to rotate at a constant speed. After the turning tool completes end face turning, the lifting frame directly drives the moving table to move downward, and the boring tool immediately enters the rotating flange cavity to fine-process the inner wall. The unique transmission gear structure (the lower gear engages the ring gear to drive the upper gear) ensures that the drilling unit (round table, chuck, drill bit) and the flange maintain precise synchronous rotation throughout the entire process. Without stopping, the turning and boring processes can be smoothly switched while the flange is continuously rotating, and the boring and drilling processes can be synchronized, greatly shortening the processing cycle.

[0023] In the present invention, when the movable platform moves downward, the elastic strip brush contacts the three-jaw chuck, and its unique trumpet-mouth structure is squeezed and adaptively deflected outward to form an umbrella-shaped isolation area. The umbrella-shaped structure effectively blocks the lateral splashing of debris in the drilling area without interfering with the drill bit. After the drill bit is withdrawn, the continuously rotating strip brush uses its contact force with the flange surface to scrape off microscopic burrs on the hole mouth, significantly improve the smoothness of the hole edge, and peel off debris adhered to the flange surface by high temperature, providing convenience for subsequent cleaning.

[0024] In the present invention, the ring frame is turned over as a whole by the turning motor, and the flange is turned down into the chip collecting groove. The chip cleaning effect is as follows: the chips on the three-jaw chuck and the flange are completely dumped and collected in the groove. Unloading effect: The ring frame continues to flip to a specific tilt angle and accurately aligns with the inclined unloading port.

[0025] After the caliper lock is released, the processed flange automatically slides out along the inclined mouth.

[0026] This allows for thorough cleaning of debris from the workpiece and rapid, automated disassembly of the workpiece itself, without the need for manual intervention. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] A transmission rod 10 is rotatably provided on the side surface of the movable table 6, and gears 11 are provided at both ends of the transmission rod 10. The outer ring of the circular table 7 is provided with an upper gear ring 12 that meshes with the upper gear 11, and the outer ring of the three-jaw chuck 3 is provided with a lower gear ring 13. When the movable table 6 moves downward, the turning tool 4 retracts, and the lifting frame 5 drives the movable table 6 to move downward, and the lower gear 11 meshes with the lower gear ring 13. During this process, the lower gear 11 of the transmission rod 10 meshes with the lower gear ring 13, and then the circular table 7 and the three-jaw chuck 3 are driven to rotate synchronously through the upper gear 11.

[0032] A movable boring tool 14 is provided on the upper side of the movable table 6 , and the boring tool 14 enters the interior of the rotating flange to perform fine processing on the inner wall thereof.

[0033] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 8 As shown, a strip brush 15 is fixedly provided at the bottom of the circular table 7, and the strip brush 15 is set as a U-shaped structure surrounding the drill bit 9. The bottom of the strip brush 15 is set as an outward-inclined bell mouth 16. When the movable table 6 moves downward, the strip brush 15 abuts against the three-jaw chuck 3 and bends outward along the bell mouth 16. After the drill bit 9 is pulled out, the circular table 7 continues to drive the strip brush 15 to rotate and brush the flange surface.

[0034] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 8 As shown, a groove 17 is provided on the base 1, and a ring frame 18 is rotatably provided in the groove 17. A flip motor 19 is fixedly provided on the side of the base 1, and the rotating shaft of the flip motor 19 is connected to the ring frame 18. The three-jaw chuck 3 is rotatably provided in the ring frame 18. After the processing is completed, the drill bit 9 and the boring tool 14 are reset, and the flip motor 19 drives the ring frame 18 to flip so that the flange flips down into the groove 17. The rotating motor 2 is fixedly mounted on the ring frame 18. A through opening 20 for collecting processing debris is provided at the bottom of the groove 17. The debris on the three-jaw chuck 3 and the flange all fall into the groove 17, and the ring frame 18 continues to flip and tilt until it is aligned with the inclined opening 21, the caliper lock is released, and the flange automatically slides out along the inclined opening 21.

[0035] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 8 As shown, one side of the base 1 is provided with an inclined opening 21 for assisting the end face tooth flange to slide out of the three-jaw chuck 3. The physical inclined surface design guides the workpiece end face tooth flange to slide automatically, avoiding the operational risks when manually disassembling the workpiece and realizing the continuity of the processing flow.

[0036] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 8 As shown, the three-jaw chuck 3 includes an annular fixed plate, and three calipers are slidably arranged on the fixed plate. The bottom of the fixed plate is rotatably provided with a control ring that uses spiral patterns to drive the displacement of the calipers. The spiral patterns of the control ring convert the rotational motion into the linear displacement of the calipers, replacing the traditional hydraulic / pneumatic clamping, avoiding the risk of fluid system leakage, and maintaining a constant clamping force through the mechanical self-locking principle.

[0037] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 8 As shown, a track 22 corresponding to the drilling motor 8 is provided on the round table 7, and a slide 23 is slidably connected in the track 22. The drilling motor 8 is fixedly mounted on the slide 23. An adjusting bolt 24 is threadedly connected to the track 22, and the adjusting bolt 24 is rotatably connected to the slide 23. When the adjusting bolt 24 rotates, it pushes the slide 23 and the drilling motor 8 and the drill bit 9 to adjust their positions. The adjusting bolt 24 and the threaded track 22 constitute a "screw-nut" fine-tuning system, which can adapt to drilling requirements of different sizes without replacing the round table 7, and realize millimeter-level mechanical positioning of the drill bit 9.

[0038] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 8 As shown, the lifting frame 5 is provided with a laser locator for detecting the vertical displacement of the moving platform 6 in real time and linking with the control system. The laser beam constructs a non-contact displacement monitoring benchmark, eliminates the measurement error caused by the mechanical contact sensor, and provides a real-time feedback signal for the closed-loop control system.

[0039] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 8 As shown, a cyclone separator is connected below the debris passage 20 to separate metal debris and coolant using a centrifugal field, thereby preventing mixed waste from clogging the recovery pipeline and achieving physical recycling and reuse of the two types of substances.

[0040] The use method and advantages of the present invention: When the processing equipment of the end face tooth flange is in operation and use, the working process is as follows: like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 8As shown: S1. Place the end face gear flange on the three-jaw chuck 3 and control the three-jaw chuck 3 to shrink and clamp the flange.

[0041] S2, the rotating motor 2 drives the three-jaw chuck 3 and the flange to rotate at a constant speed, and the turning tool 4 is radially fed to complete the turning of the flange end face. After the turning tool 4 is retracted, the lifting frame 5 drives the moving table 6 to move downward, and the boring tool 14 enters the rotating flange to fine-process its inner wall. During this process, the lower gear 11 of the transmission rod 10 is engaged with the lower gear ring 13, and then the circular table 7 and the three-jaw chuck 3 are driven to rotate synchronously through the upper gear 11, so that the drill bit 9 and the flange position are kept synchronized. In this way, while the flange keeps rotating, rapid switching between turning, boring and drilling is achieved, and the drill bit 9 and the boring tool 14 can also perform synchronous processing on the flange without the need for reciprocating start and stop to switch processes.

[0042] S3. When the movable table 6 moves downward, the strip brush 15 abuts against the three-jaw chuck 3 and deflects outward along the bell mouth 16, thereby separating the drilling area without contacting the drill bit 9. After the drill bit 9 is pulled out, the round table 7 continues to drive the strip brush 15 to rotate and brush the flange surface, thereby utilizing the elastic deformation of the strip brush 15 caused by the squeezing of the three-jaw chuck 3, and its bell mouth 16 structure forms an umbrella-shaped protective cover, which not only blocks the lateral splashing of debris, but also avoids interference with the drill bit 9. After the drill bit 9 is withdrawn, the continuously rotating strip brush 15 scrapes the hole mouth with contact force, removes the microscopic burrs produced by drilling, makes the hole edge smoother, and can also peel off the debris bonded by high temperature on the flange, which is convenient for subsequent cleaning.

[0043] S4. After the processing is completed, the drill bit 9 and the boring tool 14 are reset, and the turning motor 19 drives the ring frame 18 to turn over, so that the flange turns down into the groove 17, and the three-jaw chuck 3 and the debris on the flange all fall into the groove 17. The ring frame 18 continues to turn and tilt until it is aligned with the inclined opening 21, the caliper lock is released, and the flange automatically slides out along the inclined opening 21, thereby realizing rapid cleaning of debris and rapid disassembly of the flange.
