Embodiment Construction

[0010] 1. Welding the taillight shell and the mask can use traditional hot plate welding, ultrasonic welding, friction welding;

[0011] 2. Use the outer cover of the welded tail light to locate the connection and installation point of the whole light and the whole vehicle, and can use CNC milling die positioning or multi-point pin positioning;

[0012] 3. The connection and installation points of the tail lights determined in the processing step 2.

Abstract

A manufacture method for improving the match accuracy of the tail lamp of car includes such steps as welding the casing of tail lamp with front cover, using said front cover to determine the installation position on tail lamp, and manufacturing the installation mechanism at determined position.

Description

technical field [0001] The invention belongs to a processing method of an automobile tail light. Background technique [0002] The connection between the shell and the mask in the production of the taillight is inseparable from the welding process, and the welding accuracy is limited by the welding process itself. Due to the large deformation of the plastic material after thermal processing, and the connection and fixing points between the taillight and the vehicle are generally processed during injection molding This leads to a large error in the matching accuracy of the whole lamp after welding and the whole vehicle, which affects the matching appearance of the whole vehicle. At present, the system dimensional accuracy of hot plate welding equipment is about ±0.7mm, and the system dimensional accuracy of friction welding equipment is about ±0.4mm. It will be difficult to further improve the accuracy. Contents of the invention [0003] The invention provides a processin...
