Abstract

The invention discloses a countersinking limiting device, and relates to a simple countersinking depth limiting device mainly used for controlling the countersinking depth of an onboard radome. The problems that an existing device is complex in structure, high in operation difficulty, short in service life cycle, high in production and manufacturing cost, low in operation efficiency and product precision, and the like are solved. The simple countersinking depth limiting device is characterized by comprising a spindle (1), a stator (2), a bearing (3), an adjusting sleeve (4), a limiting nut (5), a protective casing (6) and a cover plate (7); the bearing (3) sleeves the spindle (1) in an interference fit mode at first and then is installed in the stator (2) in an interference fit mode to befixed by the cover plate (7) through screws; the outer cylindrical face of the stator (2) is provided with an external thread; the adjusting sleeve (4) and the protective casing (6) are provided withinternal threads; and the limiting nut (5), the adjusting sleeve (4) and the protective casing (6) are sequentially assembled with the stator (2) in a thread connection mode.

Description

technical field [0001] The invention relates to a countersink depth limiting device, in particular to a simple countersink depth limiting device for controlling the depth of a countersink mainly for an airborne radome. Background technique [0002] Spot facing is carried out on the airborne radome, and the requirements for the depth of the spot spot are usually very strict. When using the traditional method of spot facing, the depth is often determined by the operator's feeling, resulting in deep or shallow spot spot depth, high rework rate of parts, long production cycle and high cost. Therefore, we usually use the method of installing a limit device before the countersink to ensure the depth of the countersink. [0003] In the prior art, most of the countersink limit devices have complex structures and are not convenient to use; the connection between the main components such as the adjustment sleeve and the main shaft is not tight enough. Shaking will lead to scratches ...
