[0023] Please see Figures 1-5 This utility model discloses a welding and fixing fixture for heat transfer element caps, including a machine base 1. Two rotating rings 2 are rotatably arranged above the machine base 1. A fixed frame 3, which is in the shape of a rectangular ring, is fixedly connected between the two rotating rings 2. Two movable rods 4, which are in the shape of a U, are movably arranged on the fixed frame 3. A support plate 5 is fixedly connected to the side of the two movable rods 4 that are close to each other. A fixed rod 6 is fixedly connected to the top of the movable rod 4. A lifting sleeve 7 is movably fitted on the fixed rod 6. A pressure rod 8 is fixedly connected to the bottom of one end of the lifting sleeve 7. This welding and fixing fixture for heat transfer element caps can conveniently limit and fix the heat transfer element plate that needs to be capped, and can conveniently drive the rotating rings 2 to rotate, so that the limited heat transfer element plate can be flipped over to facilitate the welding and fixing operation of the cap.

[0024] Mounting blocks for rotating rods can be installed on both sides of the top of the machine base 1. The rotating rods are driven by a motor and a drive gear is fitted on the rotating rods. A toothed ring that meshes with the drive gear can be installed on the outer wall of the rotating ring 2 so that the toothed ring can be moved by the drive gear, thereby rotating the rotating ring 2 and serving to flip the fixed frame 3.

[0025] Specifically, the lifting sleeve 7 is hollow inside, and the top and bottom of the lifting sleeve 7 are provided with through holes 10 through which the fixing rod 6 passes.

[0026] A rack 9 is fixedly provided on one side of the fixed rod 6. The top and bottom of the lifting sleeve 7 are provided with clearance grooves 11 that communicate with the through hole 10 and the inner cavity of the lifting sleeve 7. The rack 9 passes through the clearance groove 11. The inner cavity of the lifting sleeve 7 is rotatably connected to a rotating shaft 12 on one side of the through hole 10. A gear 13 that meshes with the rack 9 is fixedly sleeved on the rotating shaft 12.

[0027] In this embodiment, the rack 9 meshes with the gear 13. Since the rack 9 is fixed and continuous, while the gear 13 can rotate, the gear 13 can move along the rack 9, so that the lifting sleeve 7 can move up and down along the fixed rod 6, thereby adjusting the height of the pressure rod 8. When the heat transfer element plate is supported by the support plate 5, the pressure rod 8 can cooperate with the support plate 5 to limit the heat transfer element plate.

[0028] Specifically, a worm gear 14 is also sleeved on the rotating shaft 12, and a worm 15 that meshes with the worm gear 14 is rotatably provided in the inner cavity of the lifting sleeve 7.

[0029] The lifting sleeve 7 is rotatably connected to a crank 16 whose end is connected to the worm gear 15.

[0030] In this embodiment, the end of the crank handle 16 extends into the inner cavity of the lifting sleeve 7 and is connected to the worm gear 15. By turning the crank handle 16, the worm gear 15 can rotate, and the worm gear 15 meshes with the transmission worm wheel 14, so that the rotating shaft 12 and the gear 13 can rotate accordingly. In turn, the gear 13 can move up and down along the rack 9 to adjust the height position of the lifting sleeve 7 and the pressure rod 8.

[0031] The worm gear 14 and worm 15 have good self-locking properties, which can facilitate the maintenance of the positions of the lifting sleeve 7 and the pressure rod 8.

[0032] Specifically, the two arms of the movable rod 4 are located on the side of the fixed frame 3. Limiting grooves 18 are provided on both sides of the fixed frame 3. The two arms of the movable rod 4 are threaded with adjusting bolts 17 whose ends can extend into the limiting grooves 18.

[0033] In this embodiment, the adjusting bolt 17 can be inserted into the limiting groove 18, making it difficult for the movable rod 4 to detach from the fixed frame 3. When the adjusting bolt 17 is tightened and the end of the adjusting bolt 17 abuts against the inner wall of the limiting groove 18, the movable rod 4 is less likely to move relative to the fixed frame 3.

[0034] In summary, this heat transfer element cap welding and fixing fixture can conveniently limit and fix the heat transfer element plate that needs to be welded and fixed, and can conveniently drive the rotating ring 2 to rotate, so that the limited heat transfer element plate can be flipped over, so as to facilitate the welding and fixing operation of the cap.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
