AI Technical Summary

Technical Problem

The positioning device and mold of the existing sealing strip welding machine are fixedly installed, which makes mold replacement cumbersome, positioning accuracy low, and affects welding quality and production efficiency.

Method used

The device employs a self-priming positioning mechanism, which uses a strong magnetic strip and a positioning beam to achieve rapid installation and precise positioning of the lower mold. Combined with the sliding cooperation of the slide rail and slider, it ensures the synchronous movement accuracy of the upper and lower molds. The detachable lower mold can adapt to the processing requirements of rubber strips of different specifications.

Benefits of technology

It enables rapid mold installation and precise positioning, improves welding accuracy and production efficiency, reduces the complexity of manual operation, and expands the scope of application.

Abstract

This utility model discloses a high-efficiency self-priming positioning device for welding sealing strips. The device is installed on the worktable of a sealing strip welding machine, with transverse plates slidably arranged on both sides of the worktable. The positioning device includes a mounting base, a lower mold, and an upper mold. The mounting base is fixed to the transverse plates, the lower mold is detachably mounted on the mounting base, and the upper end face of the upper mold is fixed to a lifting seat, allowing the upper mold to move up and down above the lower mold. Both the upper and lower end faces of the lower and upper molds are provided with receiving grooves for placing sealing strips. The upper end face of the mounting base has a first mounting groove and a second mounting groove. A strong magnetic strip is installed in the first mounting groove, and a positioning beam is installed in the second mounting groove. The bottom surface of the lower mold has a positioning groove that can be adapted to the positioning beam. The mold in this application is positioned by the strong magnetic strip adsorption and the positioning beam in conjunction with the positioning groove, preventing displacement of the mold during the sealing strip welding process and preventing misalignment problems during sealing strip welding.
