Description

Technical Field

[0001] This invention relates to the field of machinery, and more specifically to a pipe fitting processing fixture and its welding apparatus. Background Technology

[0002] Existing pipe fittings are typically fixed during welding using clamping methods. However, this presents difficulties for fixing multi-way pipe fittings, which consist of a main pipe and multiple branch pipes. Traditional clamping methods struggle to position the branch pipes, thus affecting the overall fixation of the fitting. During actual pipe fitting manufacturing, connecting components need to be installed at the opening of the branch pipe furthest from the main pipe. Because existing technologies cannot effectively position the branch pipes, the installation efficiency of the connecting components is affected. Therefore, the technical problem this application aims to solve is: how to simultaneously position the main pipe and branch pipes within the pipe fitting. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this solution effectively addresses the difficulty in positioning pipe fittings. By setting an installation groove on the mounting base, the main pipe can be installed and positioned. The first driving component can drive the push plate to move, thereby facilitating the adjustment of the positions of the first and second supports. This allows the first and second arc-shaped openings to position and lock the branch pipes. Since the main pipe and the branch pipes are fixedly connected or integrally formed, the position of the main pipe will not change after the branch pipes are positioned and locked.

Detailed Implementation

[0033] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.

[0034] like Figures 1 to 11 As shown, this embodiment proposes a pipe fitting processing fixture. The processing fixture 11 is used to clamp the pipe fitting. The pipe fitting includes a main pipe 12 and a branch pipe 13. The side of the main pipe 12 is provided with a branch pipe 13. The branch pipe 13 is used to install the connecting assembly 14. The processing fixture 11 includes: a base plate 15, a mounting base 16, a first support 17, a second support 18, and a first driving member 19.

[0035] A mounting base 16 is fixed on the base plate 15. The mounting base 16 is provided with a mounting groove 20 for mounting the main tube 12. The first support 17 is fixed on the mounting base 16 or the base plate 15, and the first support 17 has a first arc-shaped opening 21 for mounting the branch tube 13.

[0036] The first driving member 19 is mounted on the mounting base 16. The first driving member 19 has an output end that moves in a straight line. A push plate 22 is mounted on the output end of the first driving member 19. The second support 18 is fixed on the push plate 22. The second support 18 is provided with a second arc-shaped opening 23 for mounting the branch pipe 13.

[0037] This solution effectively solves the technical problem of difficult pipe positioning. By setting the mounting groove 20 on the mounting base 16, the main pipe 12 is installed and positioned. The first driving component 19 can drive the push plate 22 to move, thereby facilitating the adjustment of the positions of the first support 17 and the second support 18. This facilitates the positioning and locking of the branch pipe 13 by the first arc-shaped opening 21 and the second arc-shaped opening 23. Since the main pipe 12 and the branch pipe 13 are fixedly connected or integrally formed, the position of the main pipe 12 will not change after the branch pipe 13 is positioned and locked.

[0038] Furthermore, the first driving component 19 in this solution is a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder. The cylinder body of the first driving component 19 is fixed on one side of the mounting base 16. The mounting base 16 is provided with a through hole for the piston rod of the first driving component 19 to pass through. The push plate 22 is located on the other side of the mounting base 16 and is mounted on the piston rod of the first driving component 19.

[0039] To improve the smoothness of the push plate 22's movement, a sliding rod is fixed on the push plate 22, and a sleeve is provided on the mounting base 16. The sliding rod is slidably installed in the sliding hole of the sleeve.

[0040] In this scheme, the main tube 12 and the branch tube 13 are pre-fixed, then the main tube 12 and the branch tube 13 are installed into the processing fixture 11, and then the connecting assembly 14 is installed onto the opening at the top of the branch tube 13.

[0041] In this design, the mounting groove 20 is arranged at an angle to allow the main pipe 12 to be arranged in an inclined direction. Within the structure of the main pipe 12 and the branch pipe 13, the main pipe 12 is inclined, while the branch pipe 13 is arranged vertically.

[0042] There are four branch pipes 13, which are linearly distributed along the length of the main pipe 12 and arranged in a vertical direction.

[0043] In one embodiment of this invention, the first support 17 includes a first horizontal arm 24 and a first vertical arm 25. The first horizontal arm 24 is fixed to one side of the mounting base 16 via the first vertical arm 25, and the push plate 22 is located on the other side of the mounting base 16. The second support 18 includes a second horizontal arm 26 and a second vertical arm 27. The second horizontal arm 26 is fixed to the push plate 22 via the second vertical arm 27. The first arc-shaped opening 21 is provided on the first horizontal arm 24, and the second arc-shaped opening 23 is provided on the second horizontal arm 26.

[0044] In one embodiment of this invention, the first arc-shaped opening 21 and the second arc-shaped opening 23 are each semicircular, forming a circular opening. When the first transverse arm 24 and the second transverse arm 26 engage, the first arc-shaped opening 21 and the second arc-shaped opening 23 are joined together to form a circular opening.

[0045] Furthermore, the tops of the first transverse arm 24 and the second transverse arm 26 are respectively provided with raised steps, which are semi-circular, and the two raised steps form a circle. The outer periphery of the top of the branch pipe 13 has a first annular portion 54, which is pressed onto the raised steps.

[0046] In one embodiment of this invention, the inner wall of the first arc-shaped opening 21 of the first transverse arm 24 is provided with a first notch 28, the lower end of the first notch 28 extending to the lower surface of the first transverse arm 24. In another embodiment of this invention, the inner wall of the second arc-shaped opening 23 of the second transverse arm 26 is provided with a second notch 29, the lower end of the second notch 29 extending to the lower surface of the second transverse arm 26.

[0047] This solution, by setting a first notch 28 and a second notch 29, avoids the formation of negative pressure on the circumference of the branch pipe 13 when the first arc-shaped opening 21 and the second arc-shaped opening 23 are separated, thus facilitating the separation of the first transverse arm 24 and the second transverse arm 26.

[0048] As one embodiment of this invention, the first transverse arm 24 is provided with a clamping device, which is used to clamp the connecting component 14 onto the branch pipe 13.

[0049] The bottom outer periphery of the connecting assembly 14 has a second annular portion 55, which is pressed against the first annular portion 54, and the clamping device is used to press the second annular portion 55 downward.

[0050] As one embodiment of this example, the clamping device includes a clamping arm 30, a guide post 31, and a locking member 32. One end of the clamping arm 30 is slidably mounted on the guide post 31 in a vertical direction, and the other end of the clamping arm 30 is used to clamp the connecting assembly 14.

[0051] A spring 33 is fitted on the guide post 31. The spring 33 is located between the clamping arm 30 and the first transverse arm 24. The locking member 32 is used to lock the clamping arm 30.

[0052] The other end of the clamping arm 30 is provided with a receiving port 56, which is used to pass through the connecting assembly 14, so that the lower end of the clamping arm 30 can be pressed onto the second annular portion 55.

[0053] Furthermore, the guide post 31 is provided with an L-shaped locking groove 49, which has a vertical groove 50 and a horizontal groove 51, with the horizontal groove 51 located at the bottom of the vertical groove 50. The locking member 32 includes a collar 52 and a locking pin 53. The collar 52 is disposed on the outer periphery of the guide post 31 and is pressed against the clamping arm 30. The locking pin 53 is fixed on the collar 52 and is disposed in the L-shaped locking groove 49. The locking pin 53 can be adjusted by rotating the collar 52 and moving the collar 52 up and down. When the locking pin 53 is located in the horizontal groove 51, the clamping arm 30 clamps the second annular portion 55.

[0054] This application also proposes a welding apparatus, including the aforementioned pipe fitting processing fixture. The welding apparatus is used to weld the gap at the connection point of the connecting assembly 14, or to weld the target area according to specific welding requirements.

[0055] Furthermore, it includes a welding module 34 and a drive module 35, wherein the drive module 35 is used to drive the movement of the processing fixture 11, and the welding module 34 is used to weld the pipe fittings and connecting components 14.

[0056] Furthermore, the drive module 35 includes a mounting plate 36, a support plate 37, a frame 38, a guide rod 39, a lifting plate 40, a lifting component 41, and a moving module 42. The support plate 37 is fixed on the mounting plate 36, the frame 38 is located above the support plate 37, and the frame 38 is fixed on the support plate 37 by the guide rod 39.

[0057] The lifting plate 40 is located between the support plate 37 and the frame 38, and the lifting plate 40 can be slidably mounted on the guide rod 39 in the vertical direction;

[0058] The lifting component 41 is an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder. The lifting component 41 is mounted on the support plate 37, and the mounting plate 36 is provided with a clearance for mounting the lifting component 41. The output end of the lifting component 41 is connected to the lifting plate 40.

[0059] The movable module 42 is mounted on the lifting plate 40, and the movable module 42 is used to mount the processing fixture 11. The movable module 42 can be a one-axis module or a two-axis module, such as... Figure 6 As shown, the one-axis module uses a single linear drive component to drive the linear reciprocating motion of the machining fixture 11; as Figure 9 As shown, the two-axis module consists of two vertically arranged linear drive components used to drive the machining fixture 11 to move in a plane. Since the one-axis and two-axis modules are common mechanisms in automated equipment, their structure, installation method, and working principle will not be described in detail.

[0060] The welding module 34 in this solution is existing technology. The welding module 34 has a laser welder 43 and a drive mechanism 44. The drive mechanism 44 is fixed on the mounting plate 36 by a bracket 45. The drive mechanism 44 is a three-axis drive module in the prior art. The laser welder 43 is also existing technology.

[0061] In this design, the frame 38 has a baffle 46 in the middle, and the baffle 46 has a light-transmitting opening 47 to facilitate welding of the connecting component 14 through the light-transmitting opening 47 using a laser welder. The baffle 46 also has a clearance hole 48 for the guide post 31 to pass through.

[0062] Two openings are formed between the baffle 46 and the frame 38 to allow the processing fixture 11 to pass and avoid interference when the processing fixture 11 is lifted.

[0063] In this scheme, there are four connecting components 14. After the connecting components 14 are pre-installed on the branch pipe 13, they are pressed by the clamping device. Then, the moving module 42 drives the processing fixture 11 to the processing position. The lifting component 41 drives the processing fixture 11 and the moving module 42 to move upward as a whole, so that the connecting components 14 are aligned with the light-transmitting port 47. The laser welder welds the target area. After one connecting component 14 is welded, the lifting component 41 falls. Then, the moving module 42 drives the processing fixture 11 to move a specified distance. The lifting component 41 drives the processing fixture 11 and the moving module 42 to move upward as a whole, so that the laser welder can continue to weld the connecting components 14. The processing steps are repeated until all four connecting components 14 are welded.

[0064] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this invention, and these all fall within the protection scope of this invention.
