[0025] like Figures 1 to 6As shown, a multi-station assembly fixture includes a fixture base plate 1. A template is provided on the upper surface of the fixture base plate 1. The template includes a lower plate 8 and an upper plate 9 located on the lower plate 8. Multiple pipe grooves 10 for placing pipe fittings 19 are provided between the lower plate 8 and the upper plate 9. Each pipe groove 10 includes a lower groove 11 formed on the upper surface of the lower plate 8 and an upper groove 12 formed on the lower surface of the upper plate 9. A baffle 3 connected to the fixture base plate 1 is provided in close contact with one side of the template, and a driving component is provided on the other side of the template. A slider 4 is provided between the driving component and the template. Vertical limiting plates 2 connected to the base plate 1 of the fixture are provided on both sides of the slider 4. The two ends of the slider 4 are respectively in contact with the two limiting plates 2. The driving component is used to control the slider 4 to move closer to the template. Multiple placement holes 5 that are adapted to the tube groove 10 are opened on the side of the slider 4 facing the tube groove 10. The placement holes 5 are used to place the shaft 18. An elastic element 7 that is in contact with the shaft 18 is provided in the placement hole 5.

[0026] The pipe fitting 19 is placed on the lower groove 11 of the lower plate 8. The lower groove 11 matches the shape of the pipe fitting 19, so that the pipe fitting 19 is placed neatly. Then the upper plate 9 is placed and fixed on the lower plate 8 to restrict the pipe fitting 19. The baffle 3 is set to prevent the pipe fitting 19 from blocking the subsequent push. Then the shaft 18 is inserted into the placement hole 5 on the slider 4. Then the slider 4 is placed on the upper end face of the fixture base plate 1. The slider 4 is controlled to move towards the template by the drive component. The two limiting plates 2 are used to restrict the movement direction of the slider 4 to prevent the slider 4 from moving off course and causing the shaft 18 and the pipe groove 10 to fail to align. After the slider 4 moves, the shaft 18 on the slider 4 aligns and assembles with the pipe fitting 19 on the template. The two fit tightly to offset the performance of the gap, which facilitates the consistency of subsequent welding, improves the positioning accuracy, makes the product quality stable, and improves the processing efficiency of multi-station.

[0027] The slider 4 has protrusions at both ends facing the template. The two protrusions are located on both sides of the placement hole 5. The protrusions help to prevent over-assembly when the shaft 18 on the slider 4 is assembled with the tube 19 in the tube groove 10, and reduce the probability of damage at the connection between the shaft 18 and the tube groove 10.

[0028] To facilitate the control of the slider 4 and the assembly of the shaft 18 with the tube groove 10, the driving component includes a cam 15 rotatably mounted on the fixture base plate 1. The cam 15 is rotatably connected to the fixture base plate 1 via a rotating shaft 16. A rotating handle 17 is connected to the side wall of the cam 15 near the rotating shaft 16. Swinging the rotating handle 17 causes the protruding side of the cam 15 to press the slider 4, which facilitates bringing the shaft 18 close to the tube groove 10 and assembling it with the tube groove 10.

[0029] To facilitate the control of the slider 4 and ensure precise assembly of the shaft 18 and the tube groove 10, the driving component includes a connecting block disposed on the fixture base plate 1. A push rod is slidably connected to the connecting block. The push rod is arranged parallel to the axis of the placement hole 5. Pushing the push rod will push the slider 4, making it easier to bring the shaft 18 close to the tube groove 10 and assemble it with the tube groove 10.

[0030] The upper end face of the fixture base plate 1 is provided with a slide rail, and the lower end face of the slider 4 is provided with a slide bar that is slidably connected to the slide rail. The slide rail is arranged parallel to the axis of the placement hole 5, which facilitates the restriction of the movement trajectory of the slider 4, so that the subsequent shaft 18 and the tube groove 10 can be properly connected.

[0031] The elastic element 7 can be an elastic spring, which facilitates the elastic push of the shaft 18 close to the tube groove 10.

[0032] like Figure 3 and Figure 5 As shown, a plug 6 is provided at the end of the placement hole 5 away from the template. The plug 6 abuts against the elastic member 7. The elastic member 7 is located between the plug 6 and the shaft 18. The plug 6 is a screw plug, which can be removed from the placement hole 5.

[0033] An upper pressure plate 13 is provided on the upper plate 9. The lower end face of the upper pressure plate 13 is provided with a receiving groove to accommodate the upper plate 9. The upper pressure plate 13 is fixedly connected to the fixture base plate 1 by bolt threads.

[0034] A positioning base plate 14 is installed under the base plate 1 of the fixture. After the shaft 18 is pushed toward the pipe 19 and assembled with the pipe 19, the upper pressure plate 13 is placed on the upper plate 9 and locked to the base plate 1 of the fixture. The whole assembly is placed into the positioning base plate 14, and the shaft 18 and the pipe 19 are then welded. After the welding is completed, the assembly can be removed.

[0035] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.
