Description

An electric tricycle car state automatic riveting machine

technical field

The invention belongs to the technical field of riveting machines, in particular to an integrated automatic riveting machine for an electric tricycle.

Background technique

The riveting machine is a kind of mechanical equipment capable of punching and riveting. The car state of the electric tricycle is a component of the electric tricycle, which is installed near the wheel. The car state is composed of an outer frame and a baffle, and the two are riveted by rivets.

In the prior art, when the automatic riveting integrated machine for riveting the car state of the electric tricycle is processing the workpiece, the punching components and riveting components are distributed left and right in the horizontal direction. When punching, the linear motor drives the car state to move as a whole, and then performs Punching. After the punching is completed, the linear motor drives the car body to move a certain distance, so that the processed hole is located directly below the riveted component, and then adds rivets for riveting. In this way, the whole processing process needs the linear motor to drive the car body to move twice, reducing the In order to improve the work efficiency, and because the processed hole needs to be moved to the bottom of the riveted component after punching, it is easy to produce errors and affect the riveting effect.
