Abstract

The invention provides an automatic riveting mechanism for hollow rivets, belongs to the technical field of automatic riveting equipment, and is used for solving the technical problems of low workingefficiency and poor riveting quality of existing manual riveting. The automatic riveting mechanism comprises a mechanical arm, a riveting mechanism and a hollow rivet used for being connected with a workpiece; the riveting mechanism is linearly mounted at the end of the mechanical arm; a CCD camera is arranged at the tail end of the mechanical arm; the riveting mechanism comprises a mounting base,a fixing base and a riveting base; the fixing base is connected with the mounting base through a pin shaft; the riveting base is slidably connected with the lower end of the fixing base; a pluralityof cylinders are evenly distributed between the riveting base and the fixing base; a solid positioning cylinder is arranged at the lower end of the fixing base; a stamping boss matched with the positioning cylinder is arranged at the lower end of the riveting base; the positioning cylinder passes through the middle of the stamping boss; and the diameter of the positioning cylinder is smaller thanthe inner diameter of the hollow rivet. The automatic riveting mechanism for the hollow rivets not only can accurately position the hollow rivets, but also can efficiently complete riveting tasks in ahigh-precision manner.

Description

technical field [0001] The invention belongs to the technical field of automatic riveting equipment, and relates to an automatic riveting mechanism, in particular to an automatic riveting mechanism for a hollow rivet. Background technique [0002] At present, hollow rivet riveting technology is widely used in automobile, aerospace and precision workpiece manufacturing industries, so the demand for hollow rivet riveting mechanism is also increasing day by day. Existing hollow rivet riveting devices generally include a base and a rotating column rotatably connected to the base, and the operator can turn the rotating shaft outwards to perform riveting according to requirements. [0003] However, this kind of operation requires a lot of manpower and energy. Due to the limited energy of the operator, it is easy to cause missing riveting, and the force used in the operation process is determined by the operator based on his own experience, which cannot guarantee a certain riveting...
