Description

Hot riveting welding assembly for car lamp

Technical Field

The utility model relates to the field of welding technique, specifically be a hot rivet welding subassembly for car light.

Background

The welding machine has various types, such as single-point single function, single-point double function and single-point multiple function (the welding machine also has only one welding head, and can weld any angle between 90 degrees and 180 degrees after the form of the positioning plate is changed). And two-point, three-point, four-point and even six-point welding machines, four-corner welding machines and the like. Different types of welders also have different welding functions and work efficiencies. Welding is the process of joining metal parts using various fusible alloys (solders). The melting point of the solder is lower than that of the material to be welded, so that the welding is completed by intermolecular connection between the surfaces of the parts without melting the parts.

Application number is CN201720242250.5, the name is a but utility model patent of hot rivet welding machine of rotation work, comprises a workbench, the top fixedly connected with rivet welding frame of workstation, two spliced poles of fixedly connected with between the top of rivet welding frame inner wall and the bottom, the cope match-plate pattern has been cup jointed between two spliced poles, the bottom fixedly connected with locating lever of cope match-plate pattern, hot rivet welding head has been cup jointed to the bottom of locating lever to hot rivet welding head's top is passed the cope match-plate pattern and is connected with the output shaft transmission of cope match-plate pattern top fixed connection's motor. This hot rivet welding machine of rotatable work makes motor work, makes hot rivet welding head can be rotary motion in the locating lever, makes hot rivet welding machine in work, and hot rivet welding head self can rotary motion, and the machinery on the welding lower bolster that can be better can not damage hot rivet welding head, makes hot rivet welding machine's life extension, has also strengthened this hot rivet welding machine's work efficiency simultaneously.

However, in use, since the operation is troublesome when hot-tack welding is performed on a component such as a vehicle lamp, a hot-tack welded assembly for a vehicle lamp has been designed.
