Problems solved by technology

[0002] After the center disk is processed by the traditional turning and milling process, due to the high precision requirements of the center disk, it is necessary to accurately detect the outer diameter, thickness of the disk surface and the inner hole of the center disk. When testing the inner hole of the center disk, If the center hole is deflected, it will cause errors in the inner hole diameter test, so it is necessary to ensure the verticality of the center hole of the center disc

Abstract

The invention discloses an inner bore detection mechanism for a central plate. The detection mechanism comprises a lifting test sliding table (1), a support rod (3) and a support platform (5). The lifting test sliding table (1) is installed on the support rod (3) in a sliding mode; and the support rod (3) is installed at one side of the support platform (5). A plurality of support plates (7) that are distributed uniformly at the same circumference are installed on the support platform (5) at the peripheral direction; rotating plates (10) are hinged to the inner sides of the support plates (7) by hinging shafts (4); and gaps are left between the support plates (7) and the rotating plates (10). A reset spring (8) and a rotating cylinder (9) are installed in the gaps. Testing heads (13) are installed at the tops of the rotating plates (10); contact sensors (11) are installed at the inner side walls of the testing heads (13); and the contact sensors (11) are arranged in the central hole of the central plate. The inner bore detection mechanism has advantages of simple structure, convenient testing, and high testing precision.

Description

technical field [0001] The invention relates to an inner hole detection mechanism, in particular to a center disk inner hole detection mechanism. Background technique [0002] After the center disk is processed by the traditional turning and milling process, due to the high precision requirements of the center disk, it is necessary to accurately detect the outer diameter, thickness of the disk surface and the inner hole of the center disk. When testing the inner hole of the center disk, If the center hole is deflected, it will cause errors in the inner hole diameter test, so it is necessary to ensure the verticality of the center hole of the center disc. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art, and provide a central disc inner hole detection mechanism with simple structure, convenient testing and high testing accuracy. [0004] The object of the present invention is achieved through the follo...
