Description

Technical Field

[0001] The utility model relates to a welding auxiliary fixing device for a head and a coil, belonging to the technical field of coil welding. Background Art

[0002] For internal coil-type heat exchange water tanks, due to the differences in the internal coil's spiral structure, the inlet and outlet pipe heads can be located at either end of the internal coil or at the same end. When the inlet and outlet pipe heads are located at the same end of the internal coil, the inlet and outlet pipe heads pass through the corresponding end caps connected to the inner tank port. The two pipe heads are fixed to the caps by welding, thereby constraining the internal coil and sealing the inner tank.

[0003] At present, the welding of the heads of water exchange tanks and the water inlet and outlet pipe heads of the coils on the market is done manually. During welding, the coils and heads need to be manually supported, and it is necessary to ensure that the coils and heads are placed stably. The operation is relatively inconvenient, and the welding process is easily affected by external forces, resulting in poor welding quality. At the same time, the position of the coil is not convenient to move during welding. When there is an alignment deviation between the coils and the heads, it is easy to cause welding errors, which in turn affects the welding process. Utility Model Content

[0008] Furthermore, the L-shaped plates are symmetrically distributed on the outside of the stabilizing plate, and the pushing rods cross the inside of the L-shaped plates.

[0009] Furthermore, the clamping frame is movably connected to the outer side of the L-shaped plate through a push rod, and the positioning plate is located inside the clamping frame.

[0010] Furthermore, the reset spring is symmetrically distributed between the inner top wall of the clamping frame and the positioning plate, and the bottom of the No. 1 screw is located above the positioning plate.

[0013] The beneficial effects of the utility model are:

[0014] (1) The utility model is provided with a base, and a stabilizing plate is installed on the top of the base.

When the angle needs to be adjusted, During adjustment, first turn the No. 2 screw to rotate it inside the No. 2 threaded tube, thereby moving the No. 2 screw away from the connecting rod inside the connecting block. At this time, by turning the connecting rod, the connecting rod drives the stabilizing plate to rotate on the top of the connecting block, thereby causing the stabilizing plate to drive the coil body to adjust the angle. When the adjustment is completed, reverse the No. 2 screw to rotate it inside the No. 2 threaded tube. At this time, the No. 2 screw will reposition the connecting rod inside the connecting block, thereby facilitating the position and angle adjustment of the coil body.

[0025] Specifically, such as Figure 1 As shown, the L-shaped plate 4 is symmetrically distributed on the outside of the stabilizing plate 2, the push rod 6 crosses the inside of the L-shaped plate 4, the clamping frame 7 is movably connected to the outside of the L-shaped plate 4 through the push rod 6, the positioning plate 9 is located inside the clamping frame 7, the reset spring 8 is symmetrically distributed between the inner top wall of the clamping frame 7 and the positioning plate 9, and the bottom of the No. 1 screw 11 is located above the positioning plate 9.

[0026] In this embodiment: a base 1 is provided, and a stabilizing plate 2 is installed on the top of the base 1. When the coil body 3 on the top of the stabilizing plate 2 needs to be welded, the electric telescopic rod 5 is first started to drive the push rod 6 to move, and the clamping frame 7 is driven to move to the outside of the coil body 3 by the push rod 6. At this time, the No. 1 screw 11 is rotated to rotate inside the No. 1 threaded tube 10, and then the No. 1 screw 11 is moved downward inside the No. 1 threaded tube 10. The movement of the No. 1 screw 11 pushes the positioning plate 9 at the bottom of the return spring 8, so that the positioning plate 9 positions the coil body 3 inside the clamping frame 7 to prevent it from positional displacement during welding and replace the effect of manual support.

[0027] Example 2, please refer to Figure 1 、 Figure 2 and Figure 4The difference between this embodiment and embodiment 1 is that: the outer side of the base 1 is fixedly connected to the motor 12, the interior of the base 1 is provided with a slide groove 13, the output end of the motor 12 is fixedly connected to the screw rod 14, the outer side of the screw rod 14 is threadedly connected to the ring 15, the top of the ring 15 is fixedly connected to the moving rod 16, the top of the moving rod 16 is fixedly connected to the connecting block 17, the interior of the connecting block 17 is rotatably connected to the connecting rod 18, the outer side of the connecting block 17 is fixedly connected to the No. 2 threaded tube 19, and the interior of the No. 2 threaded tube 19 is threadedly connected to the No. 2 screw rod 20.

Since a moving rod 16 is fixedly connected to the top of the ring 15, and the moving rod 16 is slidably connected to the inside of the slide groove 13, the ring 15 will drive the moving rod 16 to move inside the slide groove 13. The moving rod 16 cooperates with the connecting block 17 to make the connecting rod 18 drive the stabilizing plate 2 to move on the top of the base 1, thereby adjusting the position of the coil body 3 on the top of the stabilizing plate 2. When the angle needs to be adjusted, When adjusting, first, by turning the No. 2 screw 20, the No. 2 screw 20 rotates inside the No. 2 threaded tube 19, and then the No. 2 screw 20 moves away from the connecting rod 18 inside the connecting block 17.

When the adjustment is completed, by reversing the No. 2 screw 20, the No. 2 screw 20 rotates and moves inside the No. 2 threaded tube 19. At this time, the No. 2 screw 20 will reposition the connecting rod 18 inside the connecting block 17, thereby achieving the effect of facilitating the position and angle adjustment of the coil body 3.
