[0025] The present invention will be further described in detail below with reference to embodiments:

[0026] Example 1

[0027] As shown in Figures 1-5, this utility model provides a positioning fixture for the production of multi-directional stress buffer joints for high-pressure pipelines, including a mounting base 1; and a PLC controller 2 disposed on the outer surface of the mounting base 1 for control. An adjustment unit 3 is disposed on the outer surface of the mounting base 1, and a clamping and positioning unit 4 is disposed on the outer surface of the adjustment unit 3. The adjustment unit 3 includes a drive assembly disposed on the outer surface of the mounting base 1 and a mounting assembly disposed on the outer surface of the drive assembly. The clamping and positioning unit 4 includes an adjustment assembly disposed on the outer surface of the adjustment unit 3 and a clamping assembly disposed on the outer surface of the adjustment assembly. The drive assembly includes a drive motor 31, one side of which is detachably connected to the outer surface of the mounting base 1. A lead screw 32 is fixedly connected to the drive end of the drive motor 31. The other end of 32 is rotatably connected to the inner wall of the mounting base 1. The mounting assembly includes a fixing plate 35. The inner wall of the fixing plate 35 is threadedly connected to the outer surface of the lead screw 32. A movable stage 34 is detachably connected to one side of the fixing plate 35. A limit slide rod 33 is slidably connected to the inner wall of the movable stage 34. Both ends of the limit slide rod 33 are detachably connected to the inner wall of the mounting base 1. When using the positioning fixture for processing the multi-directional stress buffer joint of the high-pressure pipeline, the mounting base 1 is first placed on the outer surface of the processing table. Then, the drive motor 31 is started by the PLC controller 2. The drive end of the drive motor 31 drives the lead screw 32 to rotate, thereby driving the movable stage 34 to move under the cooperation of the limit slide rod 33 and the fixing plate 35. Thus, the movable stage 34 can be adjusted to move in the horizontal direction.

[0028] Example 2

[0029] As shown in Figures 1-5, based on Embodiment 1, this utility model provides a technical solution: Preferably, the adjusting component includes a mounting plate 41, the outer surface of which is slidably connected to the outer surface of the moving platform 34, a fixing bolt 43 detachably connected to the inner wall of the mounting plate 41, and a limiting block 42 movably engaged with the outer surface of the moving platform 34 at one end of the fixing bolt 43. The clamping component includes a hydraulic cylinder 44, one end of which is detachably connected to the outer surface of the mounting plate 41, and a moving plate 47 detachably connected to the telescopic end of the hydraulic cylinder 44. A limiting strip 46 is detachably connected to one side of the moving plate 47, and a U-shaped limiting buckle 45 fixedly connected to the outer surface of the mounting plate 41 is slidably connected to the outer surface of the limiting strip 46. The clamping component includes a mounting frame 48, one end of which is fixedly connected to the outer surface of the moving plate 47, and the inner wall of the mounting frame 48 is detachable. The mounting plate 41 is connected to a fixing bolt 410, one end of which is detachably connected to an arc-shaped clamping block 49 that is detachably connected to the outer surface of the mounting frame 48. When it is necessary to clamp the multi-directional stress buffer joint of the high-pressure pipeline, the position of the mounting plate 41 is first adjusted according to the size of the multi-directional stress buffer joint of the high-pressure pipeline. During adjustment, simply rotate the fixing bolt 43, and with the help of the limiting block 42, the mounting plate 41 moves on the outer surface of the moving platform 34. After adjusting to the appropriate position, the position of the arc-shaped clamping block 49 on the mounting frame 48 is adjusted by rotating the fixing bolt 410. After the adjustment is completed, the hydraulic cylinder 44 is started, and the telescopic end of the hydraulic cylinder 44 drives the moving plate 47 to move under the limit of the U-shaped limiting buckle 45 and the limiting strip 46, thereby adjusting the position of the arc-shaped clamping block 49, thus clamping and fixing the multi-directional stress buffer joint of the high-pressure pipeline, which facilitates its processing.

[0030] The working principle of the positioning fixture used in the production of the multi-directional stress buffer joint of this high-pressure pipeline will be explained in detail below.

[0031] As shown in Figures 1-5, when using a positioning fixture to process a multi-directional stress buffer joint for high-pressure pipelines, the mounting base 1 is first placed on the outer surface of the processing table. Then, the drive motor 31 is started by the PLC controller 2. The drive end of the drive motor 31 drives the lead screw 32 to rotate, driving the moving table 34 to move under the cooperation of the limit slide rod 33 and the fixed plate 35. This allows the moving table 34 to move horizontally. When it is necessary to clamp the multi-directional stress buffer joint of the high-pressure pipeline, the position of the mounting plate 41 is first adjusted according to the size of the multi-directional stress buffer joint of the high-pressure pipeline. During adjustment, simply rotate the first fixing bolt 43, which, in conjunction with the limiting block 42, moves the mounting plate 41 on the outer surface of the moving platform 34. After adjusting to the appropriate position, rotate the second fixing bolt 410 to adjust the position of the arc-shaped clamping block 49 on the mounting frame 48. After adjustment, start the hydraulic cylinder 44. The telescopic end of the hydraulic cylinder 44 drives the moving plate 47 to move under the limits of the U-shaped limiting buckle 45 and the limiting strip 46, thereby adjusting the position of the arc-shaped clamping block 49. This clamps and fixes the multi-directional stress buffer joint of the high-pressure pipeline, making it easier to process.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
