Description
Technical Field
[0001] This utility model relates to the technical field of flange processing equipment, and in particular to a clamping device for flange processing. Background Technology
[0002] Flanges are mainly used to connect pipes and play an important role in fields such as machinery, HVAC engineering, and petrochemicals. During the processing of flanges, drilling and other procedures are required. When performing these procedures, the flanges to be processed need to be fixed and clamped. Clamping devices for flange processing are used to fix and clamp the flanges.
[0003] Existing clamping devices for flange processing are often designed with specific needs in mind, tailored for flanges of a particular diameter range. This lack of adaptability becomes even more pronounced in multi-variety, small-batch production scenarios, significantly hindering the production line's flexibility. Furthermore, the flange processing process, including drilling, generates a large amount of metal shavings. These shavings typically scatter around the clamping device, on the workbench, and even on the floor, affecting clamping stability and potentially causing workpiece positioning deviations and reducing product processing accuracy. Moreover, the scattered metal shavings pose a safety hazard, potentially injuring operators or damaging other parts of the processing equipment. Utility Model Content
[0004] Based on this, the present invention provides a clamping device for flange processing, which can quickly fix and clamp flange bodies of different sizes, as well as guide and collect metal waste generated during processing.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A clamping device for flange processing includes a clamping disc, a guide tube fixedly provided on the inner wall of the clamping disc, a fixing sleeve fixedly connected to the outer wall of the guide tube, a rubber ring provided on the inner wall of the fixing sleeve, a tapered sleeve in contact with the outer wall of the rubber ring, and a flange body in contact with the outer wall of the tapered sleeve.
[0006] A collection plate is installed at the lower end of the clamping plate, and a guide bar is welded to the inner wall of the collection plate. Both ends of the guide bar are fixedly connected to limit rods.
[0007] Preferably, the conduit is threadedly connected to the fixing sleeve, and the outer wall of the conduit is threaded.
[0008] Preferably, the inner wall of the fixing sleeve is in close contact with the outer wall of the rubber ring, and the inner diameter of the fixing sleeve is larger than the outer diameter of the rubber ring.
[0009] Preferably, the conical sleeve is movably connected to the conduit, and the inner wall of the conduit has a slotted design.
[0010] Preferably, the outer wall diameter of the flange body is the same as the outer wall diameter of the collecting tray, and the inner wall of the clamping tray is configured with a funnel-shaped structure.
[0011] Preferably, the guide bar is threadedly connected to the limiting rod, and the limiting rod is symmetrically arranged about the central axis of the guide bar.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a clamping disc to connect the conduit. The clamping disc, as the core load-bearing component, has a funnel-shaped inner wall design. This inclined inner wall structure provides a basis for adapting to flange bodies of different sizes. The clamping disc connects to the conduit, fixing and supporting the entire clamping assembly, ensuring the overall stability of the device during processing. The conduit is not only a key component connecting the clamping disc, but its outer wall is also threaded, forming a threaded connection with the fixing sleeve. This threaded engagement allows the fixing sleeve to move flexibly along the axial direction of the conduit. By rotating the fixing sleeve, its position on the conduit can be precisely adjusted. The fixing sleeve abuts against the tapered sleeve. When the fixing sleeve moves along the axial direction of the conduit, it pushes the tapered sleeve to move synchronously. Because the tapered sleeve is tapered and matches the funnel-shaped inner wall of the clamping disc, their inclination angles are mutually... When the tapered sleeve is pushed by the fixed sleeve towards the funnel-shaped inner wall of the clamping disc, the outer wall of the tapered sleeve will come into close contact with the inner wall of the clamping disc and generate radial clamping force. For flange bodies of different sizes, the position of the tapered sleeve on the guide tube can be adjusted simply by rotating the fixed sleeve. When the diameter of the flange body is large, the fixed sleeve is rotated away from the clamping disc, so that the contact position between the tapered sleeve and the inner wall of the clamping disc moves outward, thereby providing a larger clamping range. When the diameter of the flange body is small, the fixed sleeve is rotated towards the clamping disc, so that the contact position between the tapered sleeve and the inner wall of the clamping disc moves inward, ensuring that the clamping force is concentrated and stable. This structure does not require replacement of parts, and can achieve quick fixed clamping of flange bodies of different sizes through simple thread adjustment, effectively improving the adaptability and operating efficiency of the device. 2. This utility model provides a stable foundation support for the installation of the collection tray through precise cooperation with the guide bar. As the core component for waste chip collection, the collection tray has a guide bar welded to its upper end. The guide bar is compatible with the clamping disc's locking structure, ensuring that the collection tray can be accurately installed below the clamping disc, further guaranteeing the stability of the collection tray during processing. The device is equipped with limiting rods, which fix both sides of the guide bar, restricting its displacement in the lateral direction. This reliably limits the collection tray, preventing it from shifting or falling off due to processing vibrations, and ensuring that waste chips fall accurately into the collection tray. When the clamping disc and the conical sleeve clamp the flange body, the waste generated from drilling and other processes will fall naturally along the funnel-shaped slope of the inner wall of the clamping disc under the action of gravity. Due to the good guiding properties of the funnel-shaped structure, the waste will not splash randomly, but will concentrate and slide down along the inner wall, eventually landing accurately in the collection tray directly below. This achieves centralized collection of waste without the need for an additional power device. The waste can be guided and collected by the characteristics of the structure itself, which simplifies the device structure, effectively maintains the cleanliness of the processing environment, and facilitates the unified treatment and recycling of waste in the future.

[0015] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.
[0016] like Figure 1-4The clamping device shown includes a clamping plate 1, a guide tube 2 welded to the inner wall of the clamping plate 1, a fixing sleeve 3 fixedly connected to the outer wall of the guide tube 2, the guide tube 2 and the fixing sleeve 3 being threadedly connected, and the outer wall of the guide tube 2 being threaded; a rubber ring 4 is bonded to the inner wall of the fixing sleeve 3, the inner wall of the fixing sleeve 3 and the outer wall of the rubber ring 4 being tightly fitted, and the inner diameter of the fixing sleeve 3 being larger than the outer diameter of the rubber ring 4; a tapered sleeve 5 abutting against the outer wall of the rubber ring 4, the tapered sleeve 5 being movably connected to the guide tube 2, and the inner wall of the guide tube 2 being slotted; and the outer wall of the tapered sleeve 5 abutting against the flange body 6.
[0017] The clamping disc 1 connects to the guide tube 2. As a core load-bearing component, the clamping disc 1 features a funnel-shaped inner wall design. This inclined inner wall structure provides a basis for adapting to flange bodies 6 of different sizes. The clamping disc 1 connects to the guide tube 2, fixing and supporting the entire clamping assembly, ensuring the overall stability of the device during processing. The guide tube 2 is not only a key component connecting the clamping disc 1, but its outer wall is also threaded, forming a threaded connection with the fixing sleeve 3. This threaded engagement allows the fixing sleeve 3 to move flexibly along the axial direction of the guide tube 2. By rotating the fixing sleeve 3, its position on the guide tube 2 can be precisely adjusted. The fixing sleeve 3 abuts against the tapered sleeve 5. When the fixing sleeve 3 moves along the axial direction of the guide tube 2, it pushes the tapered sleeve 5 to move synchronously. Because the tapered sleeve 5 is tapered and matches the funnel-shaped inner wall of the clamping disc 1, their inclination angles are mutually matched. When the tapered sleeve 5 is pushed by the fixed sleeve 3 towards the funnel-shaped inner wall of the clamping disc 1, the outer wall of the tapered sleeve 5 will come into close contact with the inner wall of the clamping disc 1, generating a radial clamping force. For flange bodies 6 of different sizes, the position of the tapered sleeve 5 on the guide tube 2 can be adjusted simply by rotating the fixed sleeve 3. When the diameter of the flange body 6 is large, the fixed sleeve 3 is rotated away from the clamping disc 1, so that the contact position between the tapered sleeve 5 and the inner wall of the clamping disc 1 is moved outward, thereby providing a larger clamping range. When the diameter of the flange body 6 is small, the fixed sleeve 3 is rotated towards the clamping disc 1, so that the contact position between the tapered sleeve 5 and the inner wall of the clamping disc 1 is moved inward, ensuring that the clamping force is concentrated and stable. This structure does not require replacement of parts, and can achieve quick clamping of flange bodies 6 of different sizes through simple thread adjustment, effectively improving the adaptability and operating efficiency of the device.
[0018] like Figure 1-4 As shown, a collection plate 7 is installed at the lower end of the clamping plate 1. The outer diameter of the flange body 6 is the same as the outer diameter of the collection plate 7. The inner wall of the clamping plate 1 is set in a funnel shape. A guide bar 8 is welded to the inner wall of the collection plate 7. Both ends of the guide bar 8 are fixedly connected to limit rods 9. The guide bar 8 and the limit rods 9 are threadedly connected. The limit rods 9 are symmetrically arranged about the central axis of the guide bar 8.
[0019] The clamping disc 1 engages and secures the guide bar 8. The clamping disc 1 not only clamps the flange body 6, but its funnel-shaped inner wall also provides a crucial channel for guiding the waste debris downwards. The clamping disc 1 engages and secures the guide bar 8, providing a stable foundation for the installation of the collection tray 7 through precise cooperation with the guide bar 8. The collection tray 7, as the core component for waste debris collection, has the guide bar 8 welded to its upper end. The guide bar 8 is compatible with the clamping structure of the clamping disc 1, ensuring that the collection tray 7 can be accurately installed below the clamping disc 1, further guaranteeing the stability of the collection tray 7 during processing. The device is equipped with limiting rods 9, which fix both sides of the guide bar 8, restricting its displacement in the lateral direction, thereby controlling the collection... The collection disc 7 acts as a reliable limiter, preventing it from shifting or falling off due to processing vibrations, ensuring that waste chips fall accurately into the collection disc 7. When the clamping disc 1 and the conical sleeve 5 are used to clamp the flange body 6, the waste generated from drilling and other processes will fall naturally along the funnel-shaped slope on the inner wall of the clamping disc 1 under the action of gravity. Due to the good guiding properties of the funnel-shaped structure, the waste chips will not splash randomly, but will concentrate and slide down along the inner wall, eventually falling accurately into the collection disc 7 directly below, thus achieving centralized collection of waste chips. No additional power device is required; the guidance and collection of waste chips can be completed by utilizing the characteristics of the structure itself. This simplifies the device structure, effectively maintains the cleanliness of the processing environment, and facilitates the unified treatment and recycling of waste chips in the future.
[0020] Working principle: In use, take out the device and place it in the designated position. Secure the clamping disc 1 to the guide bar 8, and thread the limiting rod 9 onto the guide bar 8. Adhere and secure the fixing sleeve 3 to the rubber ring 4. Then, fit the flange body 6 onto the guide tube 2, and secure the conical sleeve 5 to the guide tube 2. Rotate the fixing sleeve 3 with its threads until it abuts against the conical sleeve 5. Clamp the clamping disc 1 and the conical sleeve 5 to fit flange bodies 6 of different sizes. Finally, drill holes in the flange body 6 and guide the generated waste to the collection tray 7 for subsequent unified processing. This completes the device's operation.

Those skilled in the art can modify or make equivalent substitutions to the technical solutions described in the foregoing embodiments.
