Description

Technical Field

[0001] This utility model relates to the field of external flange manufacturing technology, specifically to a rough boring device for manufacturing external flanges. Background Technology

[0002] External flanges, as key components in mechanical connections, are widely used in the connection of equipment such as pipelines, valves, and pumps. Their manufacturing precision directly affects the sealing performance, stability, and service life of the equipment. Rough boring is one of the core steps in the flange manufacturing process. It aims to remove excess material from the blank through boring, forming a bore diameter and surface quality that meet design requirements, laying the foundation for subsequent precision machining.

[0003] A search revealed a utility model patent with Chinese patent publication number CN219336044U, which discloses a rough boring device for manufacturing an outer flange. The device includes a housing, with two through holes symmetrically distributed in the bottom wall of the inner cavity of the housing. A sliding rod extending into the housing is slidably connected to both the front and rear sides of the housing. A limiting frame is fixedly installed on the opposite side of the two sliding rods. A motor base is fixedly installed on the right side wall of the inner cavity of the housing. A first motor is fixedly installed on the top of the motor base, and a turntable is fixedly installed on the output end of the first motor.

[0004] When using the above-mentioned device, after processing a flange, the finished product needs to be removed and a new workpiece needs to be installed. The operation requires multiple steps and is quite time-consuming. Furthermore, the boring period is a downtime, which is not conducive to improving work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a rough boring device for manufacturing external flanges, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rough boring device for manufacturing an outer flange, comprising a worktable, a vertically arranged support frame fixedly connected to the outer wall of one end of the worktable, a boring assembly fixedly connected to the top of the support frame, a mounting frame rotatably connected to the top of the worktable, two symmetrically arranged three-jaw chucks fixedly connected to the outer wall of the top of the mounting frame, a reversing assembly fixedly connected to the bottom of the worktable, the reversing assembly including a telescopic electric cylinder fixedly connected to one end of the inner wall of the top of the worktable, a moving rod fixedly connected to the output end of the telescopic electric cylinder, a horizontally arranged rack fixedly connected to the outside of the moving rod, an incompletely toothed ring adapted to the rack fixedly connected to the outside of the rotating shaft of the mounting frame, a reinforcing structure fixedly connected to the outside of the moving rod, a positioning structure fixedly connected to each diagonal position of the mounting frame, and a dust collection assembly fixedly connected to the bottom of the worktable.

[0007] As a further preferred embodiment of this technical solution, the reinforcement structure includes two insert rods fixedly connected to both ends of the movable rod, and the outer wall of the mounting bracket near the support frame has insertion holes adapted to the two insert rods.

[0008] This design allows for the alternating use of two three-jaw chucks, enabling the replacement of finished flanges during the downtime of machining one flange. This maximizes time utilization and improves the efficiency of the equipment. When boring a flange fixed inside the three-jaw chuck below the boring assembly, the finished flange inside the other three-jaw chuck is located on the side, allowing for the removal and installation of new flanges. After machining, the switch of the telescopic electric cylinder at the bottom of the worktable is activated, causing the cylinder to gradually retract. Its output end drives the moving rod to move synchronously. The insert rod at the end of the moving rod, which is inserted into the mounting bracket, first disengages. Then, the rack on the outside of the moving rod engages with the incomplete gear ring, causing the mounting bracket to rotate half a turn. The two three-jaw chucks fixed at the top of the mounting bracket alternate positions. Then, the moving rod continues to move, and the other insert rod on it re-inserts into the mounting bracket, reinforcing the mounting bracket and ensuring the stability of the flange during machining.

[0009] As a further preferred embodiment of this technical solution, the positioning structure includes an extension block fixedly connected to the corner of the mounting bracket, a vertically arranged second insertion rod slidably connected inside the extension block, the second insertion rod and the extension block being fixedly connected by the same spring, and a positioning hole being provided on the outer wall of the top of the workbench, one of the second insertion rods being slidably connected inside the positioning hole.

[0010] As a further preferred embodiment of this technical solution, the dust collection assembly includes a dust collection hood fixedly connected to the outer wall of the bottom of the workbench. A collection pipe is fixedly connected to one side of the outer wall of the dust collection hood. One top end of the collection pipe contacts the inner wall of the top of the mounting frame. A material drop hole adapted to the collection pipe is opened inside the mounting frame. The material drop hole is located directly below the boring assembly. A sealing plate is fixedly connected to one side of the outer wall of the dust collection hood. A suction structure is fixedly connected inside the sealing plate.

[0011] As a further preferred embodiment of this technical solution, the extraction structure includes a fan fixedly connected inside the sealing plate, and a metal mesh frame is fixedly connected to the outer wall of the sealing plate near the gas collection hood, the metal mesh frame being connected to one end of the bottom of the collection pipe.

[0012] When the fan inside the sealing plate is activated, it draws the air outward from the air collection hood and collection pipe, creating a negative pressure at the top opening of the collection pipe. This allows the debris generated during processing to be promptly removed, ensuring a clean working environment. The airflow and debris then enter the metal mesh frame, where the debris is intercepted and collected, preventing it from splashing and facilitating centralized processing.

[0013] As a further preferred embodiment of this technical solution, the boring assembly includes an electric cylinder fixedly connected to the outer wall of the top of the support frame, an installation frame fixedly connected to the output end of the electric cylinder, an electric motor fixedly connected inside the installation frame, a tool holder fixedly connected to the output end of the electric motor, and a tool clip fixedly connected to one end of the bottom of the tool holder.

[0014] As a further preferred embodiment of this technical solution, two stabilizing sleeves are fixedly connected to the inner wall of the top of the workbench, and the two stabilizing sleeves are respectively located on both sides of the workbench, with the moving rod slidably connected inside the two stabilizing sleeves.

[0015] This utility model provides a rough boring device for manufacturing external flanges, which has the following advantages: (1) By setting a reversing component, the two three-jaw chucks can be used alternately. The blank time when one of the flanges is being processed can be used to replace the finished flange, which can make full use of time and improve the working efficiency of the device. When the flange fixed inside the three-jaw chuck below the boring component is being bored, the finished flange inside the other three-jaw chuck is located on the side, which can be used to disassemble and install a new flange. After the processing is completed, the switch of the telescopic electric cylinder at the bottom of the worktable is turned on. The telescopic electric cylinder begins to gradually retract, and its output end drives the moving rod to move synchronously. The insert rod 1 inserted into the mounting frame at the end of the moving rod first disengages. Then the rack outside the moving rod meshes with the incomplete gear ring. The incomplete gear ring drives the mounting frame to rotate half a turn. The two three-jaw chucks fixed at the top of the mounting frame alternate positions. Then the moving rod continues to move, and the other insert rod 1 on it is inserted into the mounting frame again, which can realize the reinforcement of the mounting frame and ensure the stability of the flange during processing.

[0016] (2) By setting up a dust collection component, the fan inside the sealing plate is started. The fan draws the air out of the air collection hood and the collection pipe, so that the top opening of the collection pipe will generate negative pressure. The debris generated during the processing will be drawn out in time, which helps to ensure the cleanliness of the working environment. The airflow and debris then enter the metal mesh frame, and the debris will be intercepted and collected by the metal mesh frame, which can prevent debris from splashing and facilitate centralized processing.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] This utility model provides a technical solution: such as Figure 2 As shown in Figure 4, in this embodiment, a rough boring device for manufacturing an outer flange includes a worktable 1. A vertically arranged support frame 4 is fixedly connected to the outer wall of one end of the worktable 1. A boring assembly 7 is fixedly connected to the top of the support frame 4. A mounting frame 2 is rotatably connected to the top of the worktable 1. Two symmetrically arranged three-jaw chucks 3 (preferably K11 series, specific dimensions depending on the flange model to be processed) are fixedly connected to the outer wall of the top of the mounting frame 2. A reversing assembly 5 is fixedly connected to the bottom of the worktable 1. The reversing assembly 5 includes a telescopic electric cylinder 502 fixedly connected to one end of the inner wall of the top of the worktable 1. A moving rod 503 is fixedly connected to the output end of the telescopic electric cylinder 502. A horizontally arranged rack 504 is fixedly connected to the outside of the moving rod 503. An incomplete gear ring 501 adapted to the rack 504 is fixedly connected to the outside of the rotating shaft of the mounting frame 2. A reinforcing structure is fixedly connected to the outside of the moving rod 503. A positioning structure is fixedly connected to each diagonal position of the mounting frame 2. A dust collection assembly 6 is fixedly connected to the bottom of the worktable 1.

[0020] The reinforcement structure includes two insert rods 506 fixedly connected to both ends of the movable rod 503. The outer wall of the mounting bracket 2 near the support frame 4 has insertion holes that are compatible with the two insert rods 506.

[0021] When boring the flange fixed inside the three-jaw chuck 3 below the boring assembly 7, the finished flange inside the other three-jaw chuck 3 is located on the side, allowing for the removal and installation of new flanges. After machining, the switch of the telescopic electric cylinder 502 at the bottom of the worktable 1 is turned on, and the telescopic electric cylinder 502 begins to gradually retract. Its output end drives the moving rod 503 to move synchronously. The insertion rod 506 at the end of the moving rod 503, which is inserted into the mounting frame 2, first disengages. Then, the rack 504 outside the moving rod 503 meshes with the incomplete gear ring 501. The incomplete gear ring 501 drives the mounting frame 2 to rotate half a turn. The two three-jaw chucks 3 fixed at the top of the mounting frame 2 alternate positions. Then, the moving rod 503 continues to move, and the other insertion rod 506 on it is inserted into the mounting frame 2 again, which can strengthen the mounting frame 2 and ensure the stability of the flange during machining.

[0022] The positioning structure includes an extension block 507 fixedly connected to the corner of the mounting bracket 2. A vertically arranged insert rod 508 is slidably connected inside the extension block 507. The same spring 509 is fixedly connected between the insert rod 508 and the extension block 507. A positioning hole is opened on the top outer wall of the workbench 1, and one of the insert rods 508 is slidably connected inside the positioning hole.

[0023] During the rotation of the mounting bracket 2, the extension block 507, which was originally located below the boring assembly 7, moves closer to the positioning hole at the top of the worktable 1. The second insertion rod 508 is set on the extension block 507. Previously, one end of the spring 509 was connected to the extension block 507, and the other end was in an extended state due to the compression of the worktable 1. When the second insertion rod 508 moves to the top of the positioning hole at the top of the worktable 1 with the rotation of the mounting bracket 2, the spring 509 retracts and can drive the second insertion rod 508 to be inserted into it, which facilitates the reinforcement work of the mounting bracket 2.

[0024] like Figure 2 and Figure 3 As shown, the dust collection assembly 6 includes a dust collection hood 602 fixedly connected to the outer wall of the bottom of the workbench 1. A collection pipe 601 is fixedly connected to one side of the outer wall of the dust collection hood 602. One end of the top of the collection pipe 601 contacts the inner wall of the top of the mounting frame 2. The mounting frame 2 has a material drop hole adapted to the collection pipe 601. The material drop hole is located directly below the boring assembly 7. A sealing plate 603 is fixedly connected to one side of the outer wall of the dust collection hood 602. A suction structure is fixedly connected inside the sealing plate 603.

[0025] The extraction structure includes a fan 605 fixedly connected inside the sealing plate 603. A metal mesh frame 604 is fixedly connected to the outer wall of the sealing plate 603 near the gas collection hood 602. The metal mesh frame 604 is connected to one end of the bottom of the collection pipe 601.

[0026] During boring operations, the fan 605 inside the sealing plate 603 is activated. The fan 605 draws the air outward from the air collection hood 602 and the collection pipe 601, thereby creating a negative pressure at the top opening of the collection pipe 601. The debris generated during the processing is then promptly removed, which helps to ensure the cleanliness of the working environment. The airflow and debris then enter the metal mesh frame 604, where the debris is intercepted and collected, preventing debris from splashing and facilitating centralized processing.

[0027] like Figure 1 As shown in Figure 2, the boring assembly 7 includes an electric cylinder fixedly connected to the top outer wall of the support frame 4. The output end of the electric cylinder is fixedly connected to a mounting frame, and an electric motor is fixedly connected inside the mounting frame. The output end of the electric motor is fixedly connected to a tool holder, and a tool clip is fixedly connected to one end of the bottom of the tool holder.

[0028] The electric motor can start and drive the tool holder to rotate. The rotation of the tool holder drives the tool holder and the blade to rotate. Then, the electric cylinder is controlled to extend and drive the mounting frame to move down. The blade can then bore the inner hole of the flange. This structure is existing technology and will not be described in detail here. For specific details, please refer to the utility model patent with publication number CN221582090U.

[0029] like Figure 2 As shown, two stabilizing sleeves 510 are fixedly connected to the inner wall of the top of the workbench 1. The two stabilizing sleeves 510 are located on both sides of the workbench 1. The moving rod 503 is slidably connected inside the two stabilizing sleeves 510, so that the movement process and state of the moving rod 503 are sufficiently stable, which is beneficial to improving the reinforcement effect of the mounting bracket 2.

[0030] This utility model provides a rough boring device for manufacturing external flanges, the specific working principle of which is as follows: When the device is working, while boring the flange fixed inside the three-jaw chuck 3 below the boring assembly 7, the finished flange inside the other three-jaw chuck 3 is located on the side, allowing for the removal and installation of new flanges. After machining is completed, the switch of the telescopic electric cylinder 502 at the bottom of the worktable 1 is turned on, and the telescopic electric cylinder 502 begins to gradually retract. Its output end drives the moving rod 503 to move synchronously. The insert rod 506 at the end of the moving rod 503, which is inserted into the mounting frame 2, first disengages. Then, the rack 504 outside the moving rod 503 meshes with the incomplete gear ring 501. The incomplete gear ring 501 drives the mounting frame 2 to rotate half a turn, and the two three-jaw chucks 3 fixed at the top of the mounting frame 2 alternate positions. Then, the moving rod 503 continues to move, and the other insert rod 506 on it is inserted into the mounting bracket 2 again, which can strengthen the mounting bracket 2 and ensure the stability of the flange during processing. During the rotation of the mounting bracket 2, the extension block 507, which was originally located below the boring assembly 7, approaches the positioning hole at the top of the worktable 1. The second insert rod 508 is set on the extension block 507. Previously, one end of the spring 509 was connected to the extension block 507, and the other end was in an extended state due to the compression of the worktable 1. When the second insert rod 508 moves to the top of the positioning hole at the top of the worktable 1 with the mounting bracket 2 rotating half a turn, the spring 509 retracts and can drive the second insert rod 508 to be inserted into it, which facilitates the reinforcement of the mounting bracket 2.

[0031] During boring operations, the fan 605 inside the sealing plate 603 is activated. The fan 605 draws the air outward from the air collection hood 602 and the collection pipe 601, thereby creating a negative pressure at the top opening of the collection pipe 601. The debris generated during the processing is then promptly removed, which helps to ensure the cleanliness of the working environment. The airflow and debris then enter the metal mesh frame 604, where the debris is intercepted and collected, preventing debris from splashing and facilitating centralized processing.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
