Welding jig and automobile lamp manufacturing method

Abstract

The invention provides a welding jig. The welding jig comprises an upper mold and a lower mold sequentially from top to bottom, a lower jig cavity is formed in the upper surface of the lower mold, the lower surface of the upper mold is provided with an upper jig cavity corresponding to the lower jig cavity, the lower mold is provided with a positioning hole located outside the lower jig cavity, the upper mold is provided with a positioning column corresponding to the positioning hole, a groove is formed in the upper surface of the lower mold, the lower jig cavity is arranged in the groove, and the upper mold can be arranged in the groove in an attaching manner; the upper mold and the lower mold are each provided with a through hole, and the through holes penetrate the groove, the lower jig cavity and the upper jig cavity; the welding jig is accurate in positioning, simple and practical, the groove, the positioning hole and the positioning column are used for ensuring perpendicularity of the welding component in the horizontal and vertical direction; through the through holes, the heating and cooling process of the jig is quickened. On this basis, the invention further provides a method for manufacturing an automobile lamp through the welding jig.

Description

technical field [0001] The invention relates to the technical field of jigs, in particular to a welding jig and a method for manufacturing a vehicle lamp. Background technique [0002] A jig is a tool used to assist in controlling position or motion (or both). Fixtures can be divided into process assembly fixtures, project test fixtures and circuit board test fixtures. Among them, the process assembly fixtures include assembly fixtures, welding fixtures, disassembly fixtures, glue dispensing fixtures, irradiation fixtures, adjustment fixtures and cutting fixtures. [0003] Among them, the welding fixture is a welding fixture designed and manufactured according to the size coordinate points of the shape of the welded part calibrated during the design of the welding product. [0004] The welding of components in the electronics industry requires that the corresponding components have high positioning accuracy. However, in the prior art, it is difficult to achieve precise po...
