Prebending mechanism of preassembled hasp

Abstract

The invention relates to the field of processing of vehicle parts, in particular to an automatic prebending mechanism of a preassembled hasp. The automatic prebending mechanism comprises a linear driving unit, a guide unit and a pressing head; the linear driving unit is fixed on a frame; the pressing head is hinged to a moving end of the linear driving unit, and is freely suspended; the linear driving unit drives the pressing head and the guide unit to relatively move; the guide unit includes a base, a guide pin and a guide plate, wherein the guide pin is fixed on the base; any one of the base and the guide plate is fixed on the frame, and the other one is connected with the pressing head; the linear driving unit pushes the guide plate or the base to move; and when a gap of the guide plate moves to the guide pin position, the front end of the guide plate sinks, and the pressing head presses the hasp on a preassembled part to downwards bend to realize free prebending of the hasp. The guide unit provides a special moving rail to the pressing head, so that the consistency of each moving trajectory of the pressing head can be guaranteed, the bending quality is guaranteed, the working efficiency is improved, and the cost is saved.

Description

technical field [0001] The invention relates to the field of auto parts processing, in particular to an automatic pre-bending mechanism for pre-installed buckles. Background technique [0002] With the rapid development of platformization and modularization in the automobile manufacturing industry, the flexibility of the automobile production line is becoming higher and higher. Therefore, an automobile welding production line is often equipped with several models. In order to ensure the production rhythm and normal switching of multiple models at the main assembly station, the current common practice of OEMs is to arrange pre-assembly (assembly) stations for different models before the main assembly station, and connect different welding assembly stations through buckles. or a single piece, and then transported to the main assembly station for welding operations. Usually, a buckle is extended outward on the side wall outer panel, and then the buckle is bent to realize the f...

AI Technical Summary

Problems solved by technology

At present, most of the buckles are bent manually, which requires a huge amount of labor and very low work efficiency. Moreover, the bending quality of the buckles is uneven, which affects the product quality.
