Abstract
Claims
1. A flange outer diameter detection device, characterized by: The device includes a base, with a guide plate at the upper end of the base. A fixed first measuring rod and a slidable second measuring rod are connected to one side of the guide plate. A scale is provided on the side wall of the guide plate, with the "0" mark of the scale aligned with the inner side wall of the first measuring rod. A first guide rod is provided on the rear side of the guide plate, with a slidable top block fitted on the first guide rod. A positioning bolt is provided on the top block. A clearance hole is provided on the guide plate. A driving block is provided at the end of the second measuring rod. The driving block passes through the clearance hole and is fitted onto the first guide rod. The driving block and the top block are connected by a spring.
2. The flange outer diameter detection device of claim 1, wherein: The upper end of the base is provided with a sliding groove, and a second guide rod is provided in the sliding groove. The lower end of the second side rod is provided with a sliding sleeve that cooperates with the second guide rod.
3. The flange outer diameter detection device of claim 1, wherein: A handle is provided on the side wall of the second side rod.
4. The flange outer diameter detection device as described in claim 1, characterized in that: The base has an anti-slip pad on its bottom.
5. The flange outer diameter detection device of claim 1, wherein: The base has a drawer at its front end.
6. The flange outer diameter detection device of claim 1, wherein: The scale has two movable positioning blocks on one side, which are used to indicate the maximum and minimum values of the qualified outer diameter of the flange, respectively.
7. A flange outer diameter detection device as claimed in claim 6, characterized in that: The upper end of the guide plate is provided with a guide rail, and the positioning block is connected to a slider that cooperates with the guide rail via a pull rod. The slider is provided with a locking bolt.
