[0001] This utility model relates to the technical field of quality inspection tooling, and in particular to a device for detecting the slender shaft of a submersible electric pump. Background Technology

[0002] During the production process, slender shafts used in submersible electric pumps are prone to bending deformation due to their structure, which can affect the performance of the pump. Therefore, it is necessary to test the concentricity and straightness of the slender shafts to ensure that they are within the specified values.

[0003] However, existing quality inspection fixtures lack adjustability and cannot be well adapted to the inspection of products of various diameters. Utility Model Content

V-shaped supports are symmetrically arranged on the left and right sides of the upper surface of the base plate. A preliminary inspection platform is located on the rear side of the upper surface of the base plate, with its upper surface aligned with the top of the V-shaped supports. First screws are symmetrically arranged on the left and right sides of the upper surface of the preliminary inspection platform, with preliminary inspection rods threaded onto the two first screws. First nuts are tightened on the upper and lower sides of the preliminary inspection rods on the first screws. A translation screw is located on the front side of the upper surface of the base plate, connected to a drive motor. A nut seat for left-right translation is threaded onto the translation screw. Second screws are symmetrically arranged on the left and right sides of the upper surface of the nut seat, with support plates threaded onto the two second screws. Second nuts are tightened on the upper and lower sides of the support plates on the second screws. A slide rail in the front-back direction is located at the middle position of the upper surface of the support plate, with a slider slidably mounted on the slide rail. A dial indicator is mounted on the slider. Vertical plates are located on the front and rear sides of the upper surface of the slide rail, with tightening rods threaded onto the vertical plates. The two tightening rods tighten against the front and rear sides of the slider, respectively.

[0007] The upper surface of the initial inspection table has a vertical scale plate on one side of one of the first screws.

[0008] A non-conforming product collection platform is provided on the rear side of the base plate, and the bottom of the non-conforming product collection platform is equipped with casters.

[0009] The non-conforming product collection platform has an L-shaped structure.

[0010] The beneficial effects of this utility model are: this utility model can adjust the height of the initial inspection rod and the specific position and height of the dial indicator according to the slender shafts of different diameters, so as to meet the inspection needs of different products.
