Description

Technical Field

[0001] The utility model relates to the technical field of volute bracket welding, in particular to a fixing mechanism for volute bracket welding. Background Art

[0002] The volute is the water inlet pipe used for a turbine or water pump. It is named after its shape like a snail shell. The main function of the volute is to guide the water flow from the inlet steel pipe to the impeller of the turbine or water pump, so as to effectively convert mechanical energy into hydraulic energy or vice versa. This design enables the water flow to enter the impeller more evenly, thereby improving the working efficiency of the turbine or water pump.

[0003] A certain number of volute brackets need to be welded on the outer surface of the existing volute, and the welding of the volute brackets on larger volutes needs to be done manually. Since the volute bracket needs to be supported during welding, the welder cannot effectively observe whether the volute bracket is in the correct position or whether it is skewed. Therefore, the volute bracket will cause a decrease in welding quality if there is no auxiliary fixation. Therefore, the existing welding of volute brackets for larger volutes is inconvenient. For this reason, we provide a fixing mechanism for welding the volute bracket. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcoming in the prior art of lacking auxiliary fixation when welding a volute bracket for a relatively large volute, and to provide a fixing mechanism for welding the volute bracket.

[0028] Embodiment 2

[0029] As Figure 1 、 Figure 4 and Figure 5As shown in the figure, the limit block 27 is sleeved inside the fixed pipe 25. A guide groove that fits the limit block 27 is provided inside the fixed pipe 25. One side of the first clamping block 32 is fixedly connected with a slider 34. The slider 34 is sleeved inside a chute opened on the sleeve rod 31. The slider 34 is slidably connected with the sleeve rod 31. A connecting rod 35 penetrates through the first clamping block 32. The connecting rod 35 is slidably connected with the first clamping block 32. The connecting rod 35 is fixedly connected with the second clamping block 33. One end of the connecting rod 35 is fixedly connected with a limit piece 36. A spring 37 is sleeved on the outer surface of the connecting rod 35. One end of the spring 37 is fixedly connected to the outer surface of the limit piece 36. The other end of the spring 37 is fixedly connected to the inner wall of the first clamping block 32. A bearing 28 is sleeved on the outer surface of one end of the threaded rod 24. The bearing 28 is placed in a groove opened in the fixed block 21. The bearing 28 is fixedly connected with both the outer surface of the threaded rod 24 and the inner wall of the fixed block 21. One end of the worm 22 is fixedly connected with a rotating piece 29. The rotating piece 29 is placed in a rotating groove opened inside the fixed block 21. One end of the worm 22 away from the rotating piece 29 is fixedly connected with a turntable 201.

[0030] In this embodiment, by setting the clamping post 38 and using the clamping post 38 to be sleeved in a round hole opened on the volute casing bracket, the first clamping block 32 and the second clamping block 33 can better maintain the stability of the volute casing bracket while clamping the volute casing bracket. By setting the spring 37, the first clamping block 32 and the second clamping block 33 will not move after clamping the volute casing bracket, and sufficient clamping force is provided. At the same time, the pulled second clamping block 33 and the clamping post 38 can also be reset.

[0031] Working principle:

[0032] As Figures 1 - 5As shown in the figure, when the utility model is in use, the volute bracket can be clamped and fixed first. At this time, the second clamping block 33 is pulled, and the second clamping block 33 will drive the clamping column 38 away from the first clamping block 32. At the same time, the second clamping block 33 will also pull the connecting rod 35, and the spring 37 is compressed by using the connecting rod 35 and the limiting piece 36, so that the spring 37 generates elastic force. At this time, the circular hole end of the volute bracket is attached to the first clamping block 32, and the circular hole is aligned with the clamping groove opened on the first clamping block 32. Then the second clamping block 33 is released, and at this time, the elastic force of the spring 37 is instantaneously released, and the connecting rod 35, the second clamping block 33 and the clamping column 38 are reset, so that the first clamping block 32 and the second clamping block 33 can tightly clamp the volute bracket, and the clamping column 38 passes through the circular hole opened on the volute bracket and then enters the clamping groove. Then the turntable 201 can be rotated to drive the worm 22 to rotate, and the worm 22 will meshingly drive the worm wheel 23 under the action of the rotating piece 29, so that the worm wheel 23 can drive the threaded rod 24 to rotate. Furthermore, the threaded rod 24 can thread-drive the threaded sleeve 26, and the threaded sleeve 26 will move up and down under the cooperation of the limiting block 27 and the fixed pipe 25, so that the volute bracket can approach the position where the volute needs to be welded, and then the bottom plate 1 is moved, so that the volute bracket can be attached to the position where the volute needs to be welded. At this time, the volute bracket is in a stable state, and then the welder can weld the volute bracket and the volute.
