Bicycle frame assembly welding workpiece positioning and clamping tool

Abstract

A positioning and clamping fixture for bicycle frame assembly welding workpieces includes a base, a first positioning and clamping mechanism, a second positioning and clamping mechanism, a third positioning and clamping mechanism, and a fourth positioning and clamping mechanism. The base has a slide rail with a through-type structure along its central axis, and several sets of assembly holes are provided on the left and right sides of the slide rail. The first positioning support mechanism, the second positioning and clamping mechanism, the third positioning and clamping mechanism, and the fourth positioning and clamping mechanism are arranged sequentially from front to back, and are all installed on the base by bolts engaging with the assembly holes provided on the base. Each mechanism has a groove at its bottom that mates with the base slide rail and an elongated hole that mates with the bolts. This utility model, through the optimized design of the positioning and clamping structures of the various components of the bicycle frame and their interrelationships, ensures that the technical parameters of the assembled bicycle frame meet the design requirements and can be matched with welding operations of different types and sizes of bicycle frames, achieving the goals of improving the versatility of the welding fixture and product quality, and reducing production costs.
