Description

Technical Field

[0001] This utility model relates to an auxiliary fixing fixture for corrugated pipe production, belonging to the field of corrugated pipe production technology. Background Technology

[0002] Corrugated pipes, as tubular components with annular corrugated outer walls, are widely used in numerous fields such as petrochemicals, aerospace, automotive manufacturing, and building water supply and drainage due to their excellent flexibility, pressure resistance, and sealing properties. In the production process of corrugated pipes, auxiliary fixing fixtures play a crucial role. They must not only ensure the positional accuracy of the corrugated pipe during processing but also ensure that it does not shift or deform under the influence of cutting forces, pressure, and other external forces, thereby guaranteeing product quality and production efficiency.

[0003] Although existing fixing clamps can perform routine fixing operations on bellows, they have revealed many problems that urgently need to be solved in practical applications.

[0004] From a usability perspective, the current operating procedure is rather cumbersome. Before processing the corrugated pipe, workers must first place it in the designated position of the fixture and secure it initially using bolts and clips. Next, because the processing technology requires the corrugated pipe to be under tension to ensure processing accuracy, workers must manually adjust the distance between the various components of the fixture. This adjustment process not only requires frequent use of wrenches and knobs, but also requires workers to repeatedly adjust the spacing and force based on the specifications and material of the corrugated pipe, relying on experience, until the appropriate tension is achieved. Such multiple steps not only consume a lot of time and energy, increasing the workload of workers, but also significantly reduce overall production efficiency when facing batch processing tasks, causing great inconvenience to workers and seriously affecting the ease of use of the fixture, thus rendering the fixture unusable.

[0005] From a protective perspective, existing clamps use a rigid connection to the bellows. When the clamp applies pressure to the bellows, the lack of an effective buffering and pressure dispersion mechanism causes the pressure to concentrate at the contact point between the bellows and the clamp. As a thin-walled pipe, the bellows material typically possesses a degree of flexibility, making it difficult to withstand excessive localized pressure. Under rigid compression, the bellows is highly susceptible to damage such as dents, wrinkles, and even cracks, thus rendering the clamps inadequate in terms of protective function. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides an auxiliary fixing fixture for corrugated pipe production, which overcomes the shortcomings of the prior art and effectively solves the problems of insufficient ease of use and insufficient protection of the fixing fixture.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A corrugated pipe production auxiliary fixing fixture includes a frame, on both sides of which a plurality of guide grooves are symmetrically opened, and in the middle of the frame is a sliding groove.

[0009] Two sliders are slidably connected to the inner wall of the chute. A bidirectional threaded rod is threadedly connected to the middle of the two sliders. A rotating wheel is fixed at both ends of the bidirectional threaded rod. A connecting structure is provided at the upper end of the two sliders. Two clamping frames are provided on the connecting structure. The connecting structure can move the two clamping frames in opposite directions in the width direction of the frame, and can also move the two clamping frames in the length direction of the frame, so as to fix the corrugated pipe and tension it at the same time.

[0010] Preferably, the connection structure includes a connecting frame, with stabilizing grooves on both sides of the connecting frame, stabilizing blocks slidably connected to the inner walls of the two stabilizing grooves, guide rods slidably connected to the middle of the two stabilizing blocks, pulling blocks fixed to the upper ends of the two guide rods, support frames fixed to the adjacent sides of the two stabilizing blocks, fixing frames slidably connected to the adjacent sides of the two support frames, and clamping frames fixed to the adjacent ends of the two fixing frames.

[0011] Preferably, the lower middle part of the two connecting brackets is fixed to the upper end of the two sliders, the outer surface of the two sliders is slidably connected to the inner wall of the two sides of the slide groove, the middle part of the two sliders is threadedly connected to the outer surface of the two sides of the bidirectional threaded rod, the vertical cross-section of the two sliders is T-shaped, and the outer surface of the bidirectional threaded rod is rotatably connected to the inner wall of the middle part of the frame.

[0012] Preferably, the outer surface of each stabilizing block is slidably connected to the inner wall of each stabilizing groove, the vertical cross-section of each stabilizing block is I-shaped, the outer surface of each guide rod is slidably connected to the inner wall of the middle part of each stabilizing block, the outer surface of one guide rod is slidably connected to the inner wall of one guide groove, each guide groove is inclinedly opened on one side of the frame, the vertical cross-section of each guide rod is cross-shaped, the upper end of each guide rod is fixed to one side of each pulling block, and the outer surface of each pulling block is slidably connected to the inner wall of one side of each connecting frame.

[0013] Preferably, the adjacent sides of each pair of stabilizing blocks are fixed to the adjacent sides of each pair of supporting frames, the outer surface of each supporting frame is slidably connected to the inner wall of one side of each connecting frame, and the vertical cross-section of each connecting frame is U-shaped.

[0014] Preferably, each of the support frames has a groove in the middle, and a sliding plate is slidably connected to the inner wall of each groove. A spring is fixed to the separating side of each pair of adjacent sliding plates, and the proximal side of each pair of adjacent sliding plates is fixed to the separating end of each pair of adjacent fixed frames. The proximal end of each pair of adjacent fixed frames is fixed to the middle of the separating side of each pair of adjacent clamping frames. The adjacent clamping frames are arranged opposite each other, and the vertical cross-section of each clamping frame is arc-shaped.

[0015] Preferably, the proximal ends of each pair of adjacent springs are fixed to the disjoint sides of each pair of adjacent slide plates, the disjoint ends of each pair of adjacent springs are fixed to the inner walls of the disjoint sides of each pair of adjacent frame slots, each pair of adjacent frame slots penetrates the proximal sides of each pair of adjacent support frames, and the outer surface of each fixed frame is slidably connected to the inner wall of each frame slot.

This completely changes the cumbersome process of traditional fixture adjustment in steps, bringing convenience to the workers and thus improving the ease of use of the fixing fixture.

[0018] 2. This corrugated pipe production auxiliary fixing fixture uses a manually operated rotating wheel to rotate the work, allowing the support frame, frame groove, slide plate, spring, fixing frame, and clamping frame to work together to achieve a flexible clamping effect. This avoids stress concentration caused by rigid contact and effectively reduces the risk of corrugated pipe denting or cracking due to excessive extrusion, thereby improving the protective function of the fixing fixture.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example

[0025] This utility model provides an auxiliary fixing fixture for corrugated pipe production.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The system includes a frame 1, with several guide grooves 2 symmetrically arranged on both sides of the frame 1, and a sliding groove 3 in the middle of the frame 1. Two sliders 4 are slidably connected to the inner wall of the sliding groove 3. Two bidirectional threaded rods 5 are threadedly connected to the middle of the two sliders 4. Both ends of the bidirectional threaded rods 5 are fixed with wheels 6. A connecting structure is provided at the upper end of each of the two sliders 4. The connecting structure includes a connecting frame 7. A stabilizing groove 8 is arranged on both sides of the connecting frame 7. A stabilizing block 9 is slidably connected to the inner wall of each of the two stabilizing grooves 8. A guide rod 10 is slidably connected to the middle of each of the two stabilizing blocks 9. A pulling block 11 is fixed to the upper end of each of the two guide rods 10. A support frame 12 is fixed to the adjacent side of each of the two stabilizing blocks 9. A fixing frame 16 is slidably connected to the adjacent side of each of the two support frames 12. A clamping frame 17 is fixed to the adjacent end of each of the two fixing frames 16.

[0027] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4It is worth noting that the lower center of the two connecting brackets 7 is fixed to the upper ends of the two sliders 4. The outer surfaces of the two sliders 4 are slidably connected to the inner walls of both sides of the slide groove 3. The middle of the two sliders 4 is threadedly connected to the outer surfaces of both sides of the bidirectional threaded rod 5. The vertical cross-sections of the two sliders 4 are T-shaped. The outer surface of the bidirectional threaded rod 5 is rotatably connected to the inner wall of the middle part of the frame 1. The outer surface of each stabilizing block 9 is slidably connected to the inner wall of each stabilizing groove 8. The vertical cross-section of each stabilizing block 9 is I-shaped. The outer surface of each guide rod 10 is slidably connected to the inner wall of the middle part of each stabilizing block 9. One of the guide rods 10 is slidably connected to the inner wall of one of the guide grooves 2. Each guide groove 2 is inclined and opened on one side of the frame 1. The vertical section of each guide rod 10 is cross-shaped. The upper end of each guide rod 10 is fixed to one side of each pull block 11. The outer surface of each pull block 11 is slidably connected to the inner wall of one side of each connecting frame 7. The adjacent sides of each pair of adjacent stabilizing blocks 9 are fixed to the opposite sides of each pair of adjacent support frames 12. The outer surface of each support frame 12 is slidably connected to the inner wall of one side of each connecting frame 7. The vertical section of each connecting frame 7 is U-shaped.

[0028] In use, this invention involves manually rotating the wheel 6, causing the bidirectional threaded rod 5, fixed to the center of the wheel 6, to rotate synchronously. Guided by the sliding groove 3, the two opposing threads on the outer surface of the bidirectional threaded rod 5 drive the sliders 4 on both sides to slide away from each other axially. The displacement of the sliders 4 is transmitted through the connecting frame 7, causing the four stabilizing blocks 9 within the stabilizing groove 8 to move synchronously. Because the guide rod 10 passes through the stabilizing blocks 9 and is in contact with the inner wall of the inclined guide groove 2, the stabilizing blocks 9, during horizontal movement, are constrained by the inclined surface of the guide groove 2, resulting in a lateral approaching motion while moving away from each other.

[0029] This combined motion is transmitted through the support frame 12 to the slidingly connected fixed frame 16, ultimately driving the clamping frames 17 to achieve synchronous action: the diagonal clamping frames 17 stretch the bellows when moving away, while the adjacent clamping frames 17 complete lateral clamping as they move closer. This innovative design allows the clamping and tensioning processes to be completed simultaneously. The operator only needs to operate the rotating wheel 6 once to achieve stable fixing and tensioning of the bellows, realizing the effect of integrated clamping and tensioning. This completely changes the cumbersome process of step-by-step adjustment of traditional clamps, bringing convenience to the operator and thus improving the ease of use of the fixed clamp.

[0030] When faced with corrugated pipes of different lengths, the operator can pull the pull block 11 to slide the guide rod 10, which is fixedly connected to it, out of the current guide groove 2 along the through hole in the middle of the stabilizing block 9. The frame 1 has multiple sets of guide grooves 2 in different positions. The user selects the appropriate guide groove 2 according to the actual length of the corrugated pipe and then reinserts the guide rod 10. The position of the new guide groove 2 changes the appropriate corrugated pipe length, achieving precise positioning and fixing of corrugated pipes of different specifications, greatly improving the versatility and flexibility of the clamp. Example

[0031] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Based on Embodiment 1, a flexible clamping function has been added;

[0032] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that each support frame 12 has a groove 13 in the middle, and a slide plate 14 is slidably connected to the inner wall of each groove 13. A spring 15 is fixed to the side away from each pair of adjacent slide plates 14. The side near each pair of adjacent slide plates 14 is fixed to the side away from each pair of adjacent fixed frames 16. The side near each pair of adjacent fixed frames 16 is fixed to the middle of the side away from each pair of adjacent clamping frames 17. The two adjacent clamping frames 17 are arranged opposite each other. The vertical cross-section of each clamping frame 17 is arc-shaped. The side near each pair of adjacent springs 15 is fixed to the side away from each pair of adjacent slide plates 14. The side away from each pair of adjacent springs 15 is fixed to the inner wall of the side away from each pair of grooves 13. The two adjacent grooves 13 pass through the side near each pair of adjacent support frames 12. The outer surface of each fixed frame 16 is slidably connected to the inner wall of each groove 13.

[0033] In use, this invention involves manually rotating the wheel 6, causing the bidirectional threaded rod 5, fixed to the center of the wheel 6, to rotate synchronously. Guided by the sliding groove 3, the two opposing threads of the bidirectional threaded rod 5 drive the sliders 4 on both sides to slide in opposite directions along the axial direction. This displacement is transmitted through the connecting frame 7 to the four stabilizing blocks 9 within the stabilizing groove 8. Because the guide rod 10 penetrates the stabilizing block 9 and is tightly fitted to the inner wall of the inclined guide groove 2, the stabilizing block 9, when moving horizontally, is constrained by the inclined surface of the guide groove 2, resulting in a combined horizontal separation and lateral convergence motion.

[0034] The combined motion is transmitted from the support frame 12 to the fixed frame 16, driving the clamping frame 17 to perform synchronous actions: the diagonal clamping frames 17 stretch the bellows as they move away, while the adjacent clamping frames 17 complete lateral clamping. During clamping, the reaction force of the bellows keeps the clamping frames 17 that are moving closer together, causing the fixed frame 16 to remain stationary, while the two support frames 12 continue to move closer under the continuous drive of the stabilizing block 9. At this time, the spring 15, which is fixed to the inner wall of the support frame 12 slot 13, is compressed under the support of the sliding plate 14 of the fixed frame 16. The elastic force generated by the compression of the spring 15 is transmitted to the clamping frame 17 through the sliding plate 14 and the fixed frame 16 to perform a flexible and progressive clamping operation on the bellows. This elastic buffering mechanism not only provides buffer space for the bellows tension but also adaptively adjusts the clamping force to achieve a flexible clamping effect, avoiding stress concentration caused by rigid contact, effectively reducing the risk of the bellows denting or breaking due to excessive compression, thereby improving the protective function of the fixed clamp.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
