[0002] In the automotive manufacturing industry, pipe processing is a critical process that involves welding of metal or non-metallic pipes of various shapes and sizes. In order to ensure processing accuracy and efficiency, pipes need to be positioned and fixed during processing. Traditional pipe fixtures usually adopt a fixed structural design, which makes them only suitable for pipes of specific specifications. For pipes of different shapes or sizes, different fixtures need to be replaced, resulting in long production preparation time, high costs, and limited production flexibility.

[0003] With the development of the automotive industry and the advancement of technology, the requirements for pipe processing are also increasing, requiring not only higher processing accuracy, but also the ability to quickly change molds to adapt to the production mode of small batches and multiple varieties. Therefore, the development of a processing and positioning tooling that can flexibly adapt to various shapes and sizes of automotive pipes has become a key demand in the industry.

[0004] In the existing solutions, although there are some adjustable clamps, most of them can only be adjusted within a limited range and cannot meet the positioning requirements of complex-shaped pipes, or their structures are too complicated and inconvenient to operate, which affects the work efficiency in practical applications.

[0021] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0022] like Figure 1 , 3 -7, an automobile pipe processing and positioning tool provided by an embodiment of the present invention includes a supporting base plate 1, and also includes: A plane adjustment component 13 is installed on the support base plate 1, and a plurality of top support clamping components 12 are installed on the plane adjustment component 13.

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 top support roller 15 is rotatably mounted on both sides of the H-shaped frame 14.

[0023] In an embodiment of the present invention, according to the shape of the pipe 11 to be processed, the position of the top support 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 top support roller 15 and the positioning clamping assembly are adapted to the pipe 11 to be processed, thereby meeting the clamping and fixing requirements for the pipes 11 to be processed in different shapes. When performing the positioning and clamping operation, the pipe 11 to be processed is first clamped and fixed by a top support clamping assembly 12, that is, the top support telescopic cylinder 24 is controlled to extend to the specified position, and then the pipe 11 to be processed is placed on the two top support rollers 15, and then the positioning clamp is started to clamp the pipe 11 to be processed, and the positioning clamp and the two top support rollers 15 are used to cooperate to position and clamp the pipe 11 to be processed; after one top support clamping assembly 12 is fixed, the top support telescopic cylinders 24 of the remaining top support clamping assemblies 12 are controlled to extend, 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 top support clamping assembly 12 can be adaptively rotated, that is, the two top support rollers 15 are closely matched to 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.

[0024] 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 component 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 a plurality of main guide 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, a plurality of rotating handles can be arranged to facilitate manual locking and fixing.

[0025] A movable seat 9 is slidably provided on the inner side of the adjustable base 7, and 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, and 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, and convex ridges slidably connected to the side sliding grooves 8 are also fixed on both sides of the movable seat 9 to improve the stability of the movement of the movable seat 9.

[0026] By loosening the locking nut 2, the position of the adjustable base 7 can be stably adjusted; by controlling the telescopic cylinder 10 to extend and retract, the position of the movable seat 9 can be stably adjusted, thereby meeting the purpose of flexibly adjusting the top support telescopic cylinder 24 in the X and Y directions.

[0027] like Figure 1 , 3 -7, as a preferred embodiment of the present invention, the upper end of the telescopic core shaft of the top support telescopic cylinder 24 is rotatably connected to the lower end of the mounting column 21 through a swivel connector 28. The swivel connector 28 is not limited as long as it satisfies the requirement that the mounting column 21 can stably rotate relative to the top support telescopic cylinder 24.

[0028] The supporting roller 15 adopts a middle arc-shaped concave structure, which ensures the reliability of centering the pipe 11 to be processed.

[0029] A centering elastic telescopic rod 20 is provided on each side of the vertical plate 18, and the cylinder of the centering elastic telescopic rod 20 is fixedly connected to the mounting column 21. The centering elastic telescopic rod 20 adopts an arc-shaped structure, and the center of the centering 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 centering elastic telescopic rod 20 is also installed with a rolling ball 27. For the hinge of 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 centering elastic telescopic rod 20 can clamp the vertical plate 18 in the center. After the vertical plate 18 squeezes the centering elastic telescopic rod 20 on one side, the centering elastic telescopic rod 20 on the other side can maintain the original state or elastically stretch, without limitation; the use of the rolling ball 27 can reduce friction and improve reliability.

[0030] The direction adjustment member includes a worm wheel 22, a direction motor 23, a support frame 25 and a worm 26. The worm wheel 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 support telescopic cylinder 24. A worm 26 meshingly connected to the worm wheel 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 wheel 22 and the worm 26 has a self-locking effect, can maintain stability after direction adjustment, and is flexible and reliable.

[0031] 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 clamping telescopic cylinder 19 to retract, 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 top support roller 15; the circular frame 29 is limited to a sliding connection with the vertical plate 18, so as 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.

[0032] Preferably, in order to ensure the reliability of the positioning clamp 16 in clamping the pipe 11 to be processed, the positioning clamp 16 includes a bent clamp 30, a swing arm 31 and an inner bent portion 32. The lower portion of the swing arm 31 is rotatably connected to the support shaft 34, and the lower end of the swing arm 31 is connected to the inner bent portion 32. The inner bent portion 32 is an end away from the swing arm 31 that is bent upward in an arc shape. The push-pull rod 33 is hinged to the end of the inner bent portion 32 away from the swing arm 31 at one end away from the circular frame 29. The upper end of the swing arm 31 is connected to a bent clamp 30, and the bent clamp 30 is an end away from the swing arm 31 that is bent in an arc shape toward the middle of the H-shaped frame 14. The inner bent portion 32 can be used to increase the clamping swing range of the positioning clamp 16, and the clamping action can be completed in a small space (i.e., the movable opening 17). The bent clamp 30 can be used to prevent the pipe 11 to be processed from falling off, thereby improving the reliability of the support roller 15 and the positioning clamp 16 in clamping the pipe 11 to be processed.

[0033] The above embodiment of the present invention provides a positioning tool for automobile pipe processing, and the working principle is as follows: According to the shape and size of the pipe 11 to be processed, the operator first adjusts the position of the top support clamping assembly 12 in the X and Y directions on the supporting base plate 1 through the plane adjustment assembly 13. At the same time, the mounting column 21 is driven to rotate through the direction adjustment member (such as the worm gear 22 and the worm 26 mechanism) so that the top support roller 15 and the positioning clamping member adapt to the shape of the pipe 11 to be processed.

[0034] Select a top support clamping assembly 12 as the starting point, control the top 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 top support rollers 15. Start the positioning clamping member (such as the bending chuck 30) to initially fix the pipe 11 to be processed together with the top support rollers 15.

[0035] When the first top support clamping assembly 12 completes the initial fixation of the pipe 11 to be processed, the remaining top support clamping assemblies 12 act in sequence. Since the vertical plate 18 is hingedly connected to the mounting column 21, and the central elastic telescopic rod 20 provides central elastic support, the vertical plate 18 can adaptively rotate as the top support telescopic cylinder 24 extends, ensuring that the two top support rollers 15 closely match the shape of the pipe 11 to be processed, thereby improving the reliability of the support.

[0036] After all the top support 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.

[0037] In summary, the present invention not only improves the adaptability and flexibility of processing automobile pipes of different shapes and sizes, but also ensures the stability and precision of the pipes during the processing.

[0038] The PLC controller disclosed in the prior art can be used to control each component. The model and circuit connection of each component are not specifically limited and can be flexibly set in actual application.

[0039] The circuits, electronic components and modules involved are all prior art 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.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.
