The driving end of a servo motor 3 installed at the middle position of the tooling support frame 2 is sequentially connected to the upper flipping tooling 7 through a lower synchronous pulley 4, a synchronous belt 5, an upper synchronous pulley 6 and a transmission shaft 9, and the transmission shaft 9 is installed on the top of the tooling support frame 2 through a shaft support frame 8.

[0035] The flipping tooling 7 includes a tooling body 15. Both the left and right sides of the tooling body 15 are connected to the outer transmission shaft 9 through shaft mounting blocks 16. Along the vertical direction on the tooling body 15, a number of mounting horizontal grooves 17 are evenly distributed. At the middle position of the mounting horizontal grooves 17, a mounting vertical groove 18 is provided. Two heating sheets 20 to be processed are respectively placed in the mounting horizontal grooves 17, and the convex portions near the middle of the heating sheets 20 are located in the mounting vertical grooves 18.

[0036] On the tooling body 15 on one side of the top of the mounting horizontal grooves 17 on both sides of the mounting vertical groove 18, a rotating shaft hole 19 is provided. One side of the top of a pressing plate 21 is rotatably installed in the rotating shaft hole 19 through a rotating shaft 22.

[0037] Among them, a number of mounting horizontal grooves 17 are evenly distributed along the vertical direction at the front end and the rear end on the tooling body 15.

[0038] The second embodiment of the flipping tooling:

[0039] On the tooling body 15 on one side of the top of the mounting horizontal grooves 17 near the left or right side, a rotating shaft hole 19 is provided. One side of the top of a pressing plate 21 is rotatably installed in the rotating shaft hole 19 through a rotating shaft 22.

[0040] At the bottom of the support base 1, there is also an equipment platform 10.

On the support base 1 directly above the sliding grooves 11, there are clamping grooves 12. The bottom of the locking bolt 13 passes through the clamping groove 12 and is then connected to the sliding block 14 located in the sliding groove 11. The sliding block 14 can freely move in the sliding groove 11 in the front-back direction. The sliding groove 11 is an inverted T-shaped groove, and the sliding block 14 is an inverted T-shaped block. The bottom of the locking bolt 13 is connected to the lower sliding block 14 by means of a thread.

[0041] A brief description of the working process of the present utility model:

[0042] (1) Use belt drive to flip the flipping tooling 7, so as to realize multi-piece welding in one furnace.

[0043] (2) Locate the flipping tooling 7 and press the workpiece, i.e., the heating sheet 20, with the pressing plate 21, so as to realize positioning and ensure welding stability.

[0044] (3) Pretreatment before welding, pickling, scraping and acetone cleaning.

[0045] (4) Press the edge of the welding position with the pressing plate 21 to ensure the flatness of the weld seam.

[0046] (5) Electron beam welding, lay the weld seam flat and complete the electron beam welding.

[0047] (6) Use the flipping function to flip the other side and continue welding.

[0048] (7) X-ray flaw detection, and the electron beam welding shall meet the welding quality grade I of GJB1718A-2005.

[0049] (8) Treatment of the reinforcement height on the front and back of the weld seam.

[0050] The locking bolt 13 and the sliding block 14 of this tooling adopt the fixing mechanism of T-shaped nut and screw, so that the tooling can be firmly attached to the platform surface, ensuring excellent stability in a complex welding environment. The specially arranged installation cross groove 17 inside the tooling is used to accurately place the heating sheet 20. By fixing each part with the pressing plate 21, this not only ensures the consistency of the welding effect, prevents the deformation of parts caused by temperature changes during the welding process, ensures the welding quality and processing accuracy, but also greatly improves the welding efficiency and reduces the welding cost by flipping through the flipping function.
