[0002] Thin-walled tubular fittings are characterized by their lightness, material saving, space saving, and versatility, and have been widely used in many fields such as aviation, aerospace, and nuclear power. However, due to their thin walls, poor rigidity, and susceptibility to the effects of gravity, cutting force, cutting heat, and vibration during machining, thin-walled tubular fittings are prone to deformation and are difficult to achieve the required machining accuracy.

[0003] To address the aforementioned problems, existing patent (CN217371443U) discloses a clamping fixture for slender, thin-walled tubular components, comprising a mandrel and two positioning blocks. Several sets of tensioning components are sleeved on the surface of the mandrel, connected end-to-end. The positioning blocks are sleeved on the mandrel, with the tensioning components positioned between two positioning blocks. This invention, by providing a clamping fixture for slender, thin-walled tubular components, can reduce positioning errors, improve positioning accuracy, avoid deflection deformation caused by the slender, thin-walled tubular components, overcome tool chatter, and thus reduce the processing difficulty of slender, thin-walled tubular components, reduce deformation, and more easily meet processing accuracy requirements.

[0004] However, the aforementioned existing technologies are not convenient for adaptation and adjustment according to the size of thin-walled pipe fittings, resulting in limited adaptability to thin-walled pipe fittings. Utility Model Content

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] This utility model provides a clamping fixture for thin-walled pipe fittings, including a central rod 101 and an adjustment mechanism. The adjustment mechanism includes an adjustment rod 102, a rotating disk 103, and a telescopic assembly. The telescopic assembly includes an arc-shaped disk 104, a telescopic rod 105, a sliding rod 106, a spring 107, a support plate 108, a locking element, a connecting rod 109, and a base 110. The locking element includes a telescopic spring 111, a connecting block 112, an anti-slip block 113, an anti-slip layer 114, a fixing rod 115, and a lifting buckle 116. The aforementioned solution solves the problem that it is inconvenient to adapt and adjust according to the size of thin-walled pipe fittings, resulting in limited adaptability to thin-walled pipe fittings.

[0021] In this specific embodiment, the adjusting rod 102 is rotatably connected to the central rod 101 and located inside the central rod 101. The rotating disk 103 is fixedly connected to the adjusting rod 102 and located above the adjusting rod 102. The telescopic assembly includes an arc-shaped disk 104, a telescopic rod 105, a sliding rod 106, a spring 107, a supporting plate 108, and a locking member. The arc-shaped disk 104 is fixedly connected to the adjusting rod 102 and located outside the adjusting rod 102. The telescopic rod 105 is slidably connected to the central rod 101 and located outside the arc-shaped disk 104, and the telescopic rod 105 passes through the central rod 101. The sliding rod 106 is slidably connected to the central rod 101 and passes through the telescopic rod 105. The spring 107 is disposed outside the telescopic rod 105. The supporting plate 108 is fixedly connected to the telescopic rod 105 and located outside the telescopic rod 105. On the outside, the locking member is detachably connected to the rotating disk 103 and is located above the rotating disk 103. The thin-walled tube is sleeved on the outside of the abutment plate 108. When the rotating disk 103 is rotated, the adjusting rod 102 drives the arc-shaped disk 104 to rotate. The arc-shaped disk 104 pushes the telescopic rod 105 to move outward through the arc surface. The sliding rod 106 follows the telescopic rod 105 and slides inside the central rod 101 to ensure that the telescopic rod 105 slides horizontally. The spring 107 unfolds, and the abutment plate 108 abuts against the inner wall of the thin-walled tube. An extension plate for placing the thin-walled tube is provided on the outside of the abutment plate 108, thereby fixing the thin-walled tube. When it is necessary to remove the fixation of the thin-walled tube, the rotating disk 103 reverses, the spring 107 resets and drives the abutment plate 108 to retract. This method can effectively solve the problem of inconvenience in adapting and adjusting according to the size of the thin-walled tube.

[0022] The telescopic assembly further includes a connecting rod 109 and a base 110. The connecting rod 109 is fixedly connected to the central rod 101 and is located below the central rod 101. The base 110 is fixedly connected to the connecting rod 109 and is located below the connecting rod 109. The connecting rod 109 is used to connect the base 110 and the central rod 101. The base 110 is provided with multiple threaded fixing holes to facilitate fixing the base 110 to the work platform.

[0023] Secondly, the locking component includes a telescopic spring 111 and a connecting block 112. One end of the telescopic spring 111 is fixedly connected to the center rod 101 and is located outside the rotating disk 103. The connecting block 112 is fixedly connected to the other end of the telescopic spring 111 and is located above the telescopic spring 111. The connecting block 112 drives the telescopic spring 111 to perform telescopic operations.

[0024] Meanwhile, the locking component also includes an anti-slip block 113 and an anti-slip layer 114. The anti-slip block 113 is fixedly connected to the connecting block 112 and is located outside the connecting block 112. The anti-slip layer 114 is fixedly connected to the rotating disk 103 and is located below the anti-slip block 113. The connecting block 112 uses the telescopic spring 111 to make the anti-slip block 113 abut against the anti-slip layer 114 above, thereby preventing the rotating disk 103 from rotating on its own.

[0025] In addition, the locking component also includes a fixing rod 115 and a lifting buckle 116. The fixing rod 115 is fixedly connected to the anti-slip block 113 and is located above the anti-slip block 113. The lifting buckle 116 is fixedly connected to the fixing rod 115 and is located above the fixing rod 115. The lifting buckle 116 drives the fixing rod 115 to move upward, and the anti-slip block 113 drives the telescopic spring 111 to extend. The anti-slip block 113 releases its resistance to the anti-slip layer 114. The device can be adjusted by rotating the rotating disk 103.

[0026] Using a thin-walled pipe clamping fixture according to this embodiment, by setting the adjusting rod 102, the rotating disk 103, and the telescopic assembly, in specific use, the lifting buckle 116 drives the fixing rod 115 to move upward, the anti-slip block 113 releases its resistance to the anti-slip layer 114, the rotating disk 103 is rotated, the adjusting rod 102 drives the arc-shaped disk 104 to rotate, the arc-shaped disk 104 pushes the telescopic rod 105 to move outward through the arc surface, and the sliding rod 10... 6. The telescopic rod 105 slides within the central rod 101 to ensure that the telescopic rod 105 slides horizontally. The spring 107 unfolds, and the abutment plate 108 abuts against the inner wall of the thin-walled tube, thereby fixing thin-walled tubes of different sizes. The lifting buckle 116 is released, and the anti-slip block 113 abuts against the anti-slip layer 114, thereby restricting the rotating disk 103. This allows the device to be conveniently adapted and adjusted according to the size of the thin-walled tube, effectively improving the flexibility of the device in fixing thin-walled tubes.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
