[0002] In the automotive manufacturing industry, pipe fabrication is a critical process that involves welding and other operations on metal and non-metallic pipes of various shapes and sizes. To ensure machining accuracy and efficiency, pipes need to be positioned and secured during processing. Traditional pipe fixtures typically utilize fixed structural designs, which restrict them to specific pipe sizes. For pipes of different shapes or sizes, different fixtures must be replaced, resulting in long production preparation times, high costs, and limited production flexibility.

[0003] With the development of the automotive industry and advancements in technology, the requirements for pipe processing are also increasing. These requirements not only require higher processing precision but also require the ability to quickly change molds to accommodate small-batch, high-variety production. Therefore, developing a machining and positioning tool that can flexibly adapt to a variety of shapes and sizes of automotive pipes has become a key need within the industry.

[0004] While some existing solutions offer adjustable clamps, most offer only limited adjustment ranges, failing to meet the positioning requirements for complex-shaped pipes. Alternatively, their complex structures can be inconvenient to operate, hindering efficiency in practical applications. Furthermore, traditional clamps often lack sufficient adaptability, making it difficult to maintain stable and reliable grip when handling irregularly shaped pipes, making them inconvenient to process.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a positioning tool for automobile pipe processing to overcome the shortcomings in current practical applications. Summary of the Invention

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0032] like Figure 1 、 3 -7 shows an automobile pipe processing and positioning tool provided by one embodiment of the present invention, comprising a supporting base plate 1, and further comprising:

[0033] A plane adjustment component 13 is installed on the support base 1, and a plurality of top support clamping components 12 are installed on the plane adjustment component 13. The plane adjustment component 13 can adjust the position of the top support clamping components 12 in the X and Y directions;

[0034] The plurality of supporting and clamping assemblies 12 cooperate to fix the pipe 11 to be processed at a specified height position;

[0035] The supporting and clamping assembly 12 includes an H-shaped frame 14, a supporting roller 15, a vertical plate 18, a centering elastic telescopic rod 20, a mounting column 21, a supporting telescopic cylinder 24, a direction adjustment member and a positioning clamp. The supporting telescopic cylinder 24 is fixed on the plane adjustment assembly 13. The telescopic core shaft end of the supporting telescopic cylinder 24 is rotatably mounted with the mounting column 21. The telescopic core shaft of the supporting telescopic cylinder 24 is also mounted with a direction adjustment member for driving the mounting column 21 to rotate. The upper end of the mounting column 21 is hinged with a vertical plate 18, and the upper end of the vertical plate 18 is fixed with an H-shaped frame 14. A supporting roller 15 is rotatably mounted on both sides of the H-shaped frame 14. Positioning clamps for clamping and fixing the pipe fittings 11 to be processed are also mounted on both sides of the middle of the H-shaped frame 14. A centering elastic telescopic rod 20 for elastically supporting the vertical plate 18 in the center is also mounted on the mounting column 21.

[0036] In an embodiment of the present invention, according to the shape of the pipe to be processed 11, the position of the supporting and clamping assembly 12 is adjusted in advance by the plane adjustment assembly 13, and the mounting column 21 is driven to rotate by the direction adjustment assembly, so that the supporting roller 15 and the positioning clamping assembly are adapted to the pipe to be processed 11, thereby meeting the clamping and fixing requirements for pipes to be processed 11 of different shapes. When performing the positioning and clamping operation, the pipe 11 to be processed is first clamped and fixed by a supporting clamping assembly 12, that is, the supporting telescopic cylinder 24 is controlled to extend to the specified position, and then the pipe 11 to be processed is placed on the two supporting rollers 15, and then the positioning clamp is started to clamp the pipe 11 to be processed, and the positioning clamp and the two supporting rollers 15 are used to cooperate to position and clamp the pipe 11 to be processed; after one supporting clamping assembly 12 is fixed, the supporting telescopic cylinders 24 of the remaining supporting clamping assemblies 12 control the extension. Because the vertical plate 18 is hingedly connected to the mounting column 21, and the central elastic telescopic rod 20 elastically supports the vertical plate 18 in the center, the vertical plate 18 of the supporting clamping assembly 12 can be adaptively rotated, that is, the two supporting rollers 15 are closely matched with the shape of the pipe 11 to be processed, thereby improving the reliability of the support, and then the corresponding positioning clamp is started to complete the overall positioning and fixation of the pipe 11 to be processed.

[0037] like Figure 1-3As shown, as a preferred embodiment of the present invention, the support base plate 1 adopts a U-shaped structure, and the plane adjustment assembly 13 includes a locking nut 2, a main guide sleeve 3, a secondary guide rod 4, a main guide rod 5, a secondary guide sleeve 6, an adjustable base 7, a moving seat 9 and an adjusting telescopic cylinder 10. A main guide rod 5 is fixed on the inner side of the support base plate 1, and a secondary guide rod 4 is fixed on both sides of the main guide rod 5. The adjustable base 7 is provided with multiple main sleeves 3 slidably connected to the main guide rod 5 are fixed in the middle of the bottom of the adjustable base 7, and secondary guide sleeves 6 slidably connected to the secondary guide rod 4 are fixed on both sides of the bottom of the adjustable base 7. A locking nut 2 for locking and fixing the adjustable base 7 is also installed on the secondary guide sleeve 6, that is, the secondary guide sleeve 6 and the secondary guide rod 4 are locked and fixed by the locking nut 2, thereby ensuring the stability of the adjustable base 7; for the structure of the locking nut 2, multiple rotating handles can be arranged to facilitate manual locking and fixing.

[0038] A movable seat 9 is provided on the inner side of the adjustable base 7 for sliding movement. The lower end of the top support telescopic cylinder 24 of the top support clamping assembly 12 is fixed on the movable seat 9. An adjusting telescopic cylinder 10 is also fixed to one end of the adjustable base 7. The end of the telescopic core shaft of the adjusting telescopic cylinder 10 is fixedly connected to the movable seat 9. The position of the movable seat 9 in the adjustable base 7 can be adjusted by adjusting the telescopic cylinder 10. For the adjustable base 7, it is preferred to open side sliding grooves 8 on both sides of the cavity of the adjustable base 7. The two sides of the movable seat 9 are also fixed with ridges that are slidably connected to the side sliding grooves 8 to improve the stability of the movement of the movable seat 9.

[0039] By loosening the locking nut 2, the position of the adjustable base 7 can be stably adjusted; by controlling the extension and contraction of the telescopic cylinder 10, the position of the movable seat 9 can be stably adjusted, thereby meeting the purpose of flexible adjustment of the top support telescopic cylinder 24 in the X and Y directions.

[0040] like Figure 1 、 3 -7, as a preferred embodiment of the present invention, the upper end of the telescopic core shaft of the supporting telescopic cylinder 24 is rotatably connected to the lower end of the mounting column 21 through a rotary connector 28. The rotary connector 28 is not limited as long as it satisfies the requirement that the mounting column 21 can rotate stably relative to the supporting telescopic cylinder 24.

[0041] The supporting roller 15 adopts a central arc-shaped concave structure, which ensures the reliability of centering the pipe 11 to be processed.

[0042] A central elastic telescopic rod 20 is provided on each side of the vertical plate 18. The cylinder of the central elastic telescopic rod 20 is fixedly connected to the mounting column 21. The central elastic telescopic rod 20 adopts an arc-shaped structure, and the center of the central elastic telescopic rod 20 is located on the axis of the hinge shaft between the vertical plate 18 and the mounting column 21. The telescopic end of the central elastic telescopic rod 20 is also installed with a rolling ball 27. For the hinge connection between the vertical plate 18 and the mounting column 21, a notch can be opened at the lower end of the vertical plate 18, and then a hinge connection can be made. The vertical plate 18 is also perpendicular to the plane where the H-shaped frame 14 is located, which improves the overall reasonable reliability. The central elastic telescopic rod 20 can clamp the vertical plate 18 in the center. After the vertical plate 18 squeezes the central elastic telescopic rod 20 on one side, the central elastic telescopic rod 20 on the other side can maintain its original state or elastically extend, without limitation. The use of the rolling ball 27 can reduce friction and improve reliability.

[0043] The direction adjustment component includes a worm gear 22, a direction motor 23, a support frame 25 and a worm 26. The worm gear 22 is fixed to the lower part of the mounting column 21, and the support frame 25 is fixed to the telescopic core shaft of the top supporting telescopic cylinder 24. A worm 26 meshing with the worm gear 22 is rotatably mounted on the support frame 25. A direction motor 23 for driving the worm 26 to rotate is also fixed on the support frame 25. The arrangement of the worm gear 22 and the worm 26 has a self-locking effect, can maintain stability after direction adjustment, and is flexible and reliable.

[0044] The positioning clamping parts include a positioning clamp 16, a clamping telescopic cylinder 19, a circular frame 29, a push-pull rod 33 and a support shaft 34. A movable opening 17 is respectively opened on both sides of the middle part of the H-shaped frame 14. The positioning clamp 16 is rotatably installed in the movable opening 17 through the support shaft 34. The lower end of the positioning clamp 16 is hinged with a push-pull rod 33, and the other end of the push-pull rod 33 is hinged on the circular frame 29. The circular frame 29 is slidably sleeved on the vertical plate 18. The clamping telescopic cylinder 19 is also fixed to the two ends of the lower side of the circular frame 29, and the cylinder body of the clamping telescopic cylinder 19 is also fixedly connected to the side wall of the vertical plate 18. By controlling the contraction of the clamping telescopic cylinder 19, the positioning clamp 16 can be pulled to rotate around the support shaft 34 through the push-pull rod 33, so that the two positioning clamps 16 cooperate to clamp and fix the pipe 11 to be processed on the upper side of the supporting roller 15; the sliding connection between the circular frame 29 and the vertical plate 18 is limited to improve the stability of the movement of the circular frame 29, thereby improving the consistency of the clamping operation of the two positioning clamps 16.

[0045] The cam 32 is connected to the support 31 of the second frame 14 so that the cam 32 can move freely, and the cam 32 of the second frame 14 can move freely.

[0046] The above embodiment of the present invention provides a positioning tool for processing automobile pipe fittings, and its working principle is as follows:

[0047] Based on the shape and size of the pipe 11 to be processed, the operator first adjusts the X and Y positions of the support clamp assembly 12 on the support base 1 using the plane adjustment assembly 13. Simultaneously, the mounting column 21 is driven to rotate by a direction adjustment member (e.g., a worm gear 22 and worm 26 mechanism) so that the support roller 15 and the positioning clamp adapt to the shape of the pipe 11 to be processed.

[0048] Select a support clamping assembly 12 as the starting point, control the support telescopic cylinder 24 to raise the mounting column 21 to the specified position, and then place the pipe 11 to be processed on the two support rollers 15. Start the positioning clamping member (such as the bending chuck 30) and use it together with the support rollers 15 to initially fix the pipe 11 to be processed.

[0049] After the first support and clamping assembly 12 completes the initial fixation of the pipe 11 to be processed, the remaining support and clamping assemblies 12 are activated in sequence. Since the vertical plate 18 is hingedly connected to the mounting column 21 and a central elastic telescopic rod 20 provides central elastic support, as the support telescopic cylinder 24 extends, the vertical plate 18 can adaptively rotate, ensuring that the two support rollers 15 closely match the shape of the pipe 11 to be processed, thereby improving the reliability of the support.

[0050] After all the supporting and clamping components 12 have completed the adaptive adjustment, the corresponding positioning clamping parts are started. Through the coordinated action of the positioning clamp 16, the push-pull rod 33 and the clamping telescopic cylinder 19 and other components, the overall stable positioning and fixation of the pipe 11 to be processed is completed, and it is ready to enter the processing process.

[0051] In summary, the present invention not only improves the adaptability and flexibility in processing automobile pipe fittings of different shapes and sizes, but also ensures the stability and precision of the pipe fittings during the processing.

[0052] The control of each component can be carried out using a PLC controller disclosed in the prior art. The model and circuit connection of each component are not specifically limited and can be flexibly set in actual application.

[0053] The circuits, electronic components and modules involved are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.

[0054] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
