Sign positioning device of automatic riveting machine

Abstract

The invention discloses a sign positioning device of an automatic riveting machine. The sign positioning device comprises a gantry support and a positioning mechanism; the gantry support comprises a first gantry frame and a second gantry frame; the second gantry frame is fixedly erected on the top surface of the first gantry frame; the positioning mechanism comprises a workpiece front-end positioning assembly and a workpiece side-edge positioning assembly; the workpiece front-end positioning assembly is used for positioning the front-end length of a workpiece; and the workpiece side-edge positioning assembly is used for positioning the side-edge length of the workpiece. According to the sign positioning device, signs in multiple sizes can be positioned, the device is wide in application range, high in positioning accuracy and high in riveting quality, the labor cost is greatly reduced, the working efficiency is improved, and the device is easy to popularize and apply and has the brighteconomic benefit and social benefit prospects.

Description

technical field [0001] The invention relates to the technical field of riveting, in particular to a signboard positioning device for an automatic riveting machine. Background technique [0002] With the rapid development of basic equipment such as roads and bridges, other facilities such as billboards and traffic signs around the road are gradually improving. The existing billboards and traffic signs are all types of signs, usually two or more There are multiple pieces, and the plates need to be connected together through the cooperation of reinforcing ribs and aluminum profiles. The existing riveting operations are mostly riveted by manual riveting guns. The signboard is large in size, and there are many positions that need to be riveted. The riveting pressure is consistent. Manual riveting operations are required to be repeated, which increases the labor intensity of personnel and increases the production and molding time of signage. At the same time, when manual riveting ...

[0002] With the rapid development of basic equipment such as roads and bridges, other facilities such as billboards and traffic signs around the road are gradually improving. The existing billboards and traffic signs are all types of signs, usually two or more There are multiple pieces, and the plates need to be connected together through the cooperation of reinforcing ribs and aluminum profiles. The existing riveting operations are mostly riveted by manual riveting guns. The signboard is large in size, and there are many positions that need to be riveted. The riveting pressure is consistent. Manual riveting operations are required to be repeated, which increases the labor intensity of personnel and increases the production and molding time of signage. At the same time, when manual riveting operations are performed manually, the riveted workpiece is positioned by manual visual inspection or other positioning tools, and the positioning accuracy is low. As a result, it is difficult to maintain a uniform rivet position, and riveting errors are prone to occur, or relative stress conflicts between the plates caused by large position deviations, resulting in signs that are prone to separation and damage to the plates after riveting, and riveting guns are used on the market. , time-consuming and labor-intensive, and the riveting efficiency is low, and riveting failure is prone to occur
