Assembling device for decorative rings and shells of lamps of automobiles

Abstract

The invention relates to an assembling device for decorative rings and shells of lamps of automobiles. The assembling device is characterized in that a rotary supporting mechanism comprises a first support, a second support, a corner cylinder, a driving shaft seat, a driven shaft seat and a supporting seat, the first support and the second support are respectively mounted on a bottom plate, the corner cylinder is mounted on the first support, a rotary shaft of the corner cylinder is fixedly connected with the driving shaft seat, a rotary shaft section on the driven shaft seat is mounted on the second support via bearings, the supporting seat is connected onto the driving shaft seat and the driven shaft seat, and a shell positioning form board with a shell positioning cavity is mounted on the supporting seat; a pressing mechanism comprises at least three clamping cylinders which are respectively mounted on two sides of the supporting seat, two ends of each pressing arm are respectively connected with the corresponding clamping cylinder and a corresponding pressure head, and flexible protective cushions are arranged on the lower portions of the pressure heads. The assembling device has the advantages that scratching to surface coatings of the decorative rings is reduced, and the assembling quality and the manufacturing efficiency can be improved.

Description

technical field [0001] The invention relates to an assembly device for an automobile lamp decorative ring and a shell, and belongs to the technical field of motor vehicle lamp manufacturing. Background technique [0002] At present, in the manufacture of automobile lamps, for example, when assembling the rear combination lamp, it is necessary to first assemble the bezel or reflector with the front of the housing by crimping, and then rotate the assembled bezel housing assembly by 180°, and then Self-tapping screws are used to connect and fix the decorative ring or reflector to the housing, so the assembly of the housing and the decorative ring requires two assembly processes. Install the bezel or reflector on the shell through an assembly tool and reach the pre-tightened position, take out the bezel shell assembly, rotate the bezel shell assembly 180° and put it into the assembly tool of the next process. The tooling is positioned with the bezel as a reference, and the beze...

AI Technical Summary

Problems solved by technology

When assembling the self-tapping screws, the bezel template is positioned against the bezel, so during the assembly process of the bezel and the shell, due to the two clamping and positioning, it is easy to cause the bezel to be positioned during the loading, unloading and positioning of the bezel. Scratching of the coating on the surface of the ring reduces the yield of the lamp assembly

At the same time, due to the two assembly processes, it is necessary to install and position the shell and the bezel separately, which increases labor intensity and reduces production efficiency.
