Technical Field

[0001] This utility model belongs to the field of stainless steel sewage pump casing processing technology, and in particular relates to a processing device for stainless steel sewage pump casing. Background Technology

[0002] In the production and processing of stainless steel sewage pumps, the surface treatment of the pump casing (such as polishing and grinding) is a key step in ensuring its performance and service life.

[0003] Existing pump casing processing equipment often fails to fully expose concealed areas such as the bottom of the pump casing when fixing it, resulting in blind spots during processing and requiring multiple disassemblies and adjustments. Furthermore, traditional equipment requires manual adjustment of the clamping distance when adapting to pump casings of different specifications, which is cumbersome and inefficient. Rigid jaws are often used to directly clamp the inner walls of the pump casing's inlet and outlet. Since stainless steel has high hardness but its surface is easily scratched, this clamping method can easily cause scratches and deformation on the inner wall of the pump casing, affecting the sealing performance and appearance quality of the pump casing. This is especially true for precision-machined pump casings, where the repair cost after damage is high.

[0004] To solve the above problems, there is an urgent need for a processing device for a stainless steel sewage pump casing with a rotating function. Utility Model Content

The drive shaft 11 is rotatably connected to the positioning plate 4 at the top of the fixed base 2 via bearings, and the driven shaft 12 is rotatably connected to the positioning plate 4 at the top of the movable base 3 via bearings. The ends of the drive shaft 11 and the driven shaft 12 are respectively fixedly connected to the two fixed disks 5. This arrangement allows the stainless steel sewage pump casing to rotate at a certain angle, which facilitates the exposure of the dead corners at the bottom of the sewage pump casing, making it convenient to perform comprehensive processing on the sewage pump casing.

[0025] Furthermore, the drive assembly includes a gear 13 fixedly connected to the drive shaft 11, a rack 14 slidably connected to the positioning plate 4, the rack 14 meshing with the gear 13, and an electric actuator 15 connected to the rack 14 on the positioning plate 4.

The guide groove 18 is opened on the operating table 1, and the guide rod 19 is fixed to the bottom of the support platform 16. The hydraulic rod 17 is fixed to the operating table 1 and can drive the support platform 16 to rise and fall. The support platform 16 rises and falls on the operating table 1 through the guide rod 19 and the guide groove 18, which facilitates the raising of the stainless steel sewage pump casing and makes it easy to move the stainless steel sewage pump casing between the two three-jaw chucks 6.

[0027] Furthermore, the telescopic rod 10 is provided with a corrugated sleeve 20 on its outer side. The corrugated sleeve 20 is sleeved on the outer side of the telescopic rod 10 and can extend and retract with the telescopic rod 10, thus protecting the telescopic rod 10.

[0028] The specific working principle is as follows:

[0029] In use, first place the stainless steel sewage pump casing on the support platform 16, then raise the support platform 16 by using the hydraulic rod 17. When the stainless steel sewage pump casing is raised between the two three-jaw chucks 6, and the inlet and outlet of the sewage pump casing are aligned with the three-jaw chucks 6 on both sides, then push the moving seat 3 by the telescopic rod 10 until the two three-jaw chucks 6 fix the sewage pump casing. At this point, the sewage pump casing can be processed.

[0030] When it is necessary to process the dead corner at the bottom of the sewage pump casing, firstly, the support platform 16 is lowered by the hydraulic rod 17, and then the rack 14 is moved by the electric push rod 15. The movement of the rack 14 can drive the drive shaft 11 and the fixed plate 5 on one side to rotate through the gear 13. Since the drive shaft 11 and the driven shaft 12 are connected together by the sewage pump casing, the driven shaft 12 will rotate with the drive shaft 11. As the rack 14 moves, the bottom of the sewage pump casing will be exposed, and then the bottom of the sewage pump casing can be processed. After the processing is completed, the three-jaw chuck 6 is separated from the sewage pump casing, the telescopic rod 10 is retracted, and then the sewage pump casing can be removed.
