Description

Technical Field

[0001] This utility model relates to the field of measuring tools, specifically to a measuring tool for a vehicle-mounted optoelectronic turntable base part. Background Technology

[0002] The vehicle-mounted optoelectronic turntable base is the foundation of the entire two-axis stabilization platform. As the overall system support, it serves as the mounting base for the entire turntable (including the de-rotation axis assembly, pitch axis assembly, optical lens barrel, and all other components), and is rigidly connected to the vehicle, ship, or other carrier by means of bolts or other methods.

[0003] When inspecting the dimensions of the base parts, refer to the instruction manual attached. Figure 7 The base component has 6 holes (Ø4.2±0.05) evenly distributed around its circumference, with a center dimension of Ø102±0.05; 2 holes (Ø2) with angles of 15°±10′, 58°±5′, and Ø111. +0.035 Dimensions such as the inner hole require measurement using a projector. However, after this process, burrs may appear on the machined surfaces, such as the faceted opening, which can introduce errors during projector measurement. Therefore, the burrs must be removed before projector measurement, which is cumbersome. Furthermore, for the dimensions 15°±10′ and 58°±5′, a compact mandrel needs to be inserted into the Ø2 hole for measurement. However, the wall thickness of the Ø2 hole is thin, and the mandrel will still introduce errors, especially given the small tolerances of the parts. Projection measurement is difficult and prone to significant errors. The angular phase relationship between the Ø2 hole and the 6-Ø4.2 holes is checked visually against the drawing, which is prone to misreading and carries a certain risk. Therefore, this invention proposes a measuring tool for this base part. Utility Model Content

[0004] To overcome the deficiencies in the prior art, this utility model provides a measuring tool for a vehicle-mounted optoelectronic turntable base part. The tool mates with the Ø111 annular groove and the Ø111 outer circle of the mating plate. By aligning the Ø2 hole with the slot and inserting the corresponding Ø2 mandrel, if there is no significant resistance during the mating and insertion operations, the dimensions are considered acceptable, and measurement is achieved. A pin is inverted and inserted into the connecting hole, ensuring that the first shaft section matches the corresponding six Ø4.2 holes. If there is no significant resistance during pin insertion and rotation through the third shaft section, the dimensions are considered acceptable, and measurement is achieved.

[0005] Technical solution

[0006] A measuring tool for a vehicle-mounted optoelectronic turntable base part includes a base plate, on which a circular mating plate is provided. The mating plate is provided with a connecting hole, and a pin for fitting a Ø4.2 hole is provided in the connecting hole. The mating plate is also provided with a slot for fitting a Ø2 hole.

[0007] Furthermore, the mating plate is perfectly matched with the annular groove on the base component.

[0008] Furthermore, the slot is aligned with the Ø2 hole on the base part.

[0009] Furthermore, the pin is inserted into the Ø4.2 hole and the Ø4.2 hole is inspected.

[0010] Furthermore, the mating plate is inserted into the annular groove, and the dimensions of the annular groove are detected.

[0011] Furthermore, the pin includes a first shaft segment that adapts to the Ø4.2 hole, a second shaft segment that adapts to the connecting hole, and a third shaft segment.

[0012] Beneficial effects

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] The Ø111 annular groove is fitted with the Ø111 outer circle of the mating plate. By aligning the Ø2 hole with the slot and inserting the corresponding Ø2 mandrel, if there is no obvious resistance during the fitting and insertion operation, the dimension is qualified and measurement can be achieved. The pin is inserted upside down into the connecting hole so that the first shaft section is adapted to the corresponding 6 Ø4.2 holes. If there is no obvious resistance when inserting the pin and rotating through the third shaft section, the dimension is qualified and measurement can be achieved. Attached Figure Description
