Description

Technical Field

[0001] The utility model relates to the technical field of sewage pump casing processing, in particular to a processing device for a stainless steel sewage pump casing. Background Art

[0002] Sewage pump is used to transport raw sewage, rainwater, feces or liquid containing solids such as fiber, paper scraps, fruit, etc., and the casing of the sewage pump is usually made of stainless steel. The casing of the submersible sewage pump is generally one-piece cast. After the initial forming, it is necessary to use the submersible sewage pump casing processing tooling to position the submersible sewage pump casing for fine processing. The existing submersible sewage pump casing processing tooling is complicated to operate and takes a lot of time when in use. Therefore, it is impossible to quickly position the submersible sewage pump casing, so it is very inconvenient to use, which reduces the efficiency of the submersible sewage pump casing processing.

[0003] The publication (announcement) number is CN210281424U, which discloses a submersible sewage pump casing processing tool, including a base, a support rod fixedly connected to the upper end surface of the base, a limit tube fixedly connected to the end of the support rod away from the base, a rotating shaft rotatably connected to the inner tube wall of the limit tube, and a rotating handle fixedly connected to one end of the rotating shaft. The utility model drives the rotating shaft to rotate by rotating the rotating handle, thereby driving the first bevel gear to rotate, and then drives the second bevel gear to rotate through the meshing connection, and the second bevel gear drives the connecting rod to rotate, and the connecting rod is connected through the threaded connection, and cooperates with the limiting effect of the limiting device on the threaded pipe, drives the threaded pipe away from the fixing ring, thereby driving the mounting plate to gradually move away from the fixing ring through the threaded pipe, so that the mounting plate is against the inner wall of the submersible sewage pump casing, and the submersible sewage pump casing is fixed. Because the operation is simple and convenient, the submersible sewage pump casing can be quickly positioned.

[0004] Although the above scheme can quickly position the submersible sewage pump casing, the adjustment of the mounting plate pressed against the inner wall of the casing requires the cooperation of transmission components such as the rotating shaft, the first bevel gear and the second bevel gear, in addition to the cooperation of the threaded connector and the limiter. The equipment has a complex structure for adjusting the limiter and has a high preparation cost. Moreover, the limiter is only supported at one end of the limiter pipe. The equipment has poor placement stability for the limiter of the casing, which affects the stable processing of the casing. For this reason, we propose a processing device for the stainless steel sewage pump casing. Utility Model Content
