Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a high-efficiency machining device for the pump shaft of a submersible electric pump. Background Art

[0002] A submersible electric pump consists of three parts: the downhole part, the surface part, and the intermediate part connecting the downhole and surface parts. The downhole part is composed of a multistage centrifugal pump, a protector, and a submersible motor, which plays the main role in pumping oil and is the main unit of the submersible electric pump. Among them, the pump shaft is an important component of the submersible electric pump, so the processing technology and processing accuracy requirements for the pump shaft are extremely strict.

[0003] For example, the authorized announcement number "CN218555009U" is a machining device for a pump shaft of a submersible electric pump. Although it provides a pump shaft clamping part that is convenient for fixing pump shafts of different sizes, has strong practicability, stable connection between the pump shaft clamping part and the pump shaft, accurate positioning, and simple operation. However, the pump shaft is only driven by a fixing knob to rotate the fixing threaded rod, thereby pushing the fixing arc plate to fix the pump shaft in the pump shaft clamping part. If the pump shaft is not placed on the center line, machining deviation will occur; if the fixing is not firm, when the machining tool processes the pump shaft, the machining accuracy will be reduced.

At this time, start the vacuum cleaner 22 to ensure that the metal chips generated during machining are sucked into the storage box of the vacuum cleaner 22, and start the second cylinder 18 to extend the second telescopic rod 19 and process the pump shaft 13. When the pump shaft 13 needs to rotate, first start the third cylinder 24, then shorten the third telescopic rod 25 to disengage the second positioning block 26 from the pump shaft 13, then start the motor 9 to rotate the motor shaft 10. When it rotates to the specified position, stop the motor 9, then start the third cylinder 24 again to make the second positioning block 26 press tightly against the pump shaft 13, and then start the second cylinder 18 to process the pump shaft 13. When machining different positions in the length direction of the pump shaft 13, first start the third cylinder 24, then shorten the third telescopic rod 25 to disengage the second positioning block 26 from the pump shaft 13, then start the first cylinder 4 to extend or shorten the first telescopic rod 5 to reach the specified position, then start the third cylinder 24 again to make the second positioning block 26 press tightly against the pump shaft 13, and then start the second cylinder 18 to process the pump shaft 13.
