Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a corrugated pipe end processing device. Background Technology

[0002] Metal corrugated pipe is a type of pipe with a regular wave-like shape. Commonly used metal corrugated pipes are made of materials such as carbon steel, stainless steel, steel lined with plastic, and aluminum. Metal corrugated pipes are mainly used for non-concentric axial transmission that requires a very small bending radius, or for irregular turns, expansion and contraction, or to absorb the thermal deformation of pipes. They are also used in scenarios where it is inconvenient to install them with fixed elbows for connecting pipes to pipes or connecting pipes to equipment.

[0003] After metal corrugated pipes are cut, burrs or irregularities may appear at the ends. Therefore, grinding is required to ensure the neatness of the ends. In the existing technology, the adaptability of the inner wall of corrugated pipes of different sizes is poor. In the grinding process, it may be necessary to replace the clamps for different sizes of corrugated pipes. In some cases, only one clamp is used for positioning the corrugated pipe, which may cause the corrugated pipe to shake during the grinding process, which affects the grinding efficiency and may also cause grinding position deviation. Therefore, we urgently need a corrugated pipe end processing device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that the bellows shakes during the grinding process due to unstable clamping, and that the fit of the bellows inner wall size is poor. Therefore, a bellows port processing device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bellows end processing device includes a base and a grinding component that is lifted and mounted on the base, and a placement platform that is fixedly mounted on the base.

[0007] Multiple clamping blocks are rotatably mounted on the placement platform, and the multiple clamping blocks are arranged in a ring at equal intervals on the top surface of the placement platform. A driving unit is provided on the placement platform, which is used to drive the multiple clamping blocks to deflect and unfold and abut against the inner wall of the corrugated pipe. An auxiliary positioning component for positioning the corrugated pipe is slidably provided on the placement platform.

[0008] To position the inner wall of the corrugated pipe, preferably, the drive unit includes a gear 1 rotatably connected to a placement platform, at least two sets of rotating rods rotatably connected to the placement platform, a gear 2 fixedly connected to the end of each rotating rod, and gear 1 meshing with gear 2. A drive motor is fixedly installed at the bottom of the placement platform, and the output end of the drive motor is fixedly connected to gear 1. When the drive motor is working, gear 1 and gear 2 rotate.

[0009] To position the outer wall of the corrugated pipe, preferably, the auxiliary positioning component includes a connecting plate fixedly installed on the placement platform, a sliding plate fixedly connected to the connecting plate, a damping slide rod fixedly connected inside the sliding plate, and a bracket slidably connected to the damping slide rod, with a bonding roller fixedly connected to the bracket.

[0010] To further limit the sliding force of the bracket, the coefficient of friction between the damping slide rod and the bracket is in the range of 0.2μ-0.5μ.

[0011] To further improve the positioning effect, the number of bonding rollers is at least three sets, which are arranged in a circle at equal intervals on the outside of the placement platform. The multiple sets of bonding rollers form a clamping space for positioning the wave tube.

[0012] To accommodate various sizes of bellows inner diameters, preferably, an anti-slip pad is fixedly installed on the clamping block, and when the clamping block is unfolded, the anti-slip pad contacts the inner wall of the bellows.

[0013] In order to position the grinding component at the bellows port, preferably, a linear guide rail is fixedly connected to the base, and the grinding component is fixedly connected to the output end of the linear guide rail. When the linear guide rail is working, it drives the grinding component to reciprocate linearly along the working path.

[0014] Compared with the prior art, the present invention provides a bellows port processing device, which has the following beneficial effects:

[0015] 1. This bellows end processing device, through the setting of multiple sets of extendable clamping blocks, when the drive motor drives gear one to rotate, it will drive gear two that meshes with it to rotate. When gear two rotates, it will cooperate with the clamping blocks on the rotating rod to open or close, which can quickly adapt to various bellows inner diameters and provide a stable positioning effect on the inner wall of the bellows, improving the accuracy of bellows end processing and further improving work efficiency.

[0016] 2. This corrugated pipe end processing device, through the setting of the bonding roller, after the corrugated pipe is positioned, pushes the bracket located on the damping slide rod inside the sliding plate to bond the bonding roller to the outer wall of the corrugated pipe. Combined with the internal clamping block, the inner and outer walls of the corrugated pipe are positioned simultaneously, which effectively improves the stability of the pipe positioning during the grinding process and improves the processing accuracy of the corrugated pipe end.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model improves the adaptability to corrugated pipe inner diameters of different sizes and improves the clamping and positioning effect of corrugated pipes. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example:

[0026] Reference Figures 1-4 A corrugated pipe end processing device includes a base 1 and a grinding component 2 that is lifted and mounted on the base 1. The grinding component 2 includes a mounting plate with a detachable grinding head rotatably connected to the mounting plate, and a motor for driving the grinding head. The grinding component 2 is used to grind the end of the corrugated pipe. A linear guide rail 15 is fixedly connected to the base 1, and the grinding component 2 is fixedly connected to the output end of the linear guide rail 15. When the linear guide rail 15 is working, it drives the grinding component 2 to reciprocate linearly along the working path. Here, the linear guide rail 15 can drive the grinding component 2 to move up and down, adapting to the length of corrugated pipes of different heights. The grinding head on the grinding component 2 is used to grind the end of the corrugated pipe and remove burrs.

[0027] It also includes a placement platform 3 fixedly mounted on the base 1. Multiple clamping blocks 7 are rotatably mounted on the placement platform 3, and the clamping blocks 7 are arranged in a ring at equal intervals on the top surface of the placement platform 3. A driving unit is provided on the placement platform 3 to drive the multiple clamping blocks 7 to deflect and unfold, abutting against the inner wall of the bellows. An auxiliary positioning component for positioning the bellows is slidably mounted on the placement platform 3. The driving unit includes a gear 4 rotatably connected to the placement platform 3. At least two sets of rotating rods 5 are rotatably connected to the placement platform 3, and a gear 6 is fixedly connected to the end of each rotating rod 5, with gear 4 meshing with gear 6. A drive motor 13 is fixedly mounted at the bottom of the placement platform 3, and the output end of the drive motor 13 is fixedly connected to gear 4. Next, when the drive motor 13 is working, gear 4 and gear 6 rotate. Here, the number of rotating rods 5 is preferably five. When gear 4 rotates, it always meshes with gear 6. The other end of the rotating rod 5 is fixedly connected to a clamping block 7. Gear 6 is a quarter gear. When gear 4 rotates counterclockwise, gear 6 will rotate clockwise in coordination with rotating rod 5. In this state, clamping block 7 unfolds outward and abuts against the inner wall of the bellows. When gear 4 rotates clockwise, gear 6 will rotate counterclockwise in coordination with rotating rod 5. In this state, clamping block 7 closes inward and disengages from the inner wall of the bellows. Anti-slip pad 14 is fixedly installed on clamping block 7. When clamping block 7 unfolds, anti-slip pad 14 contacts the inner wall of the bellows.

[0028] It should be noted that gear 4 is equipped with a cover plate for collecting debris to prevent debris from affecting the transmission between gear 4 and gear 6.

[0029] Here, when the drive motor 13 drives the gear 4 to rotate, it will drive the gear 6 meshing with it to rotate. When the gear 6 rotates, it will cooperate with the clamping block 7 on the rotating rod 5 to open or close. In the open state, the clamping block 7 will adapt to and abut against different bellows inner diameters to complete the positioning of the bellows. In the closed state, the clamping block 7 will disengage from the inner wall of the bellows and release the positioning of the bellows. It should be noted that the drive motor 13 can be used to drive the gear 4 to rotate, or the drive motor 13 can be replaced by a lever, or the gear 4 can be driven to rotate manually. This effectively provides positioning and clamping for bellows of different sizes, improves the accuracy when processing the bellows port, and further improves work efficiency.

[0030] An auxiliary positioning component is slidably connected to the placement platform 3. The auxiliary positioning component includes a connecting plate 8 fixedly installed on the placement platform 3, a sliding plate 9 fixedly connected to the connecting plate 8, a damping slide rod 10 fixedly connected inside the sliding plate 9, and a bracket 11 slidably connected to the damping slide rod 10. A bonding roller 12 is fixedly connected to the bracket 11. The coefficient of friction between the damping slide rod 10 and the bracket 11 is in the range of 0.2μ-0.5μ, preferably 0.4μ, which prevents the bracket 11 from easily sliding on the damping slide rod 10, requiring external force to push it. The process involves moving the corrugated tube in a circular, equidistant arrangement of at least three sets of bonding rollers 12 on the outer side of the placement platform 3. The multiple sets of bonding rollers 12 form a clamping space for positioning the corrugated tube. Once the corrugated tube is positioned, the bracket 11 located on the damping slide rod 10 inside the sliding plate 9 is pushed to bond the bonding rollers 12 to the outer wall of the corrugated tube. Combined with the internal clamping block 7, the inner and outer walls of the corrugated tube are positioned simultaneously, effectively improving the stability of the tube positioning during the grinding process and enhancing the processing accuracy of the corrugated tube port.

[0031] In this invention, the operator places one end of the corrugated pipe on the surface of the placement table 3. At this time, the clamping block 7 is in a closed state and located inside the corrugated pipe. The drive motor 13 drives the gear 4 to rotate, causing the gear 6 meshing with it to rotate simultaneously. At this time, the clamping block 7 rotates and unfolds in conjunction with the rotating rod 5, so that the anti-slip pad 14 on the clamping block 7 is in contact with the inner wall of the corrugated pipe, achieving primary positioning. Then, by pushing the bracket 11, it slides towards the corrugated pipe on the damping slide rod 10 and is in contact with the outer wall of the corrugated pipe through the bonding roller 12, achieving secondary positioning. At this time, the output end of the drive linear guide 15 drives the grinding part 2 to move downward, and the grinding head is used to grind one end of the corrugated pipe. After the processing is completed, the drive motor 13 drives the gear 4 to rotate, and in conjunction with the gear 6, closes the clamping block 7, disengaging the bonding roller 12 from the corrugated pipe, so that the corrugated pipe can be taken out. After turning the corrugated pipe over, the above operation is repeated to complete the processing of the other end of the corrugated pipe.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
