Perancangan Meja Welding Fixture Portable Dengan Fitur Tilt And Lock Untuk Fabrikasi Behel Belakang Sepeda Motor

Abstract

Manufacturing motorcycle rear brackets requires high dimensional accuracy to ensure precise bolt mounting holes when installed on the vehicle frame. Inaccurate joint positioning during manual welding often leads to heat distortion and product defects. This study designed a portable welding fixture table that functions as a jig and fixture to rigidly lock the bracket pipe structure. The main table plate dimensions are designed at 24 x 20 inches with a zinc-plated steel surface to optimize electrical conductivity and corrosion resistance. To improve ergonomics, the table is equipped with a tilt and lock mechanism at 0°, 30°, and a folded position, as well as telescopic legs for height adjustment. Additional features such as guide rails and a lower storage shelf are integrated to improve work efficiency in the workshop. The design results show that the table structure can support loads of up to 158 kg with a stable caster wheel mobility system, thus ensuring a more accurate and efficient motorcycle bracket manufacturing process.
