Welding device for automobile seat

Abstract

The invention discloses a welding device for an automobile seat, and relates to the field of automobile part manufacturing. The welding device comprises a servo turntable, a fixed shell, a sleeve positioning and feeding device, a front end fixing device, a rear end fixing device and supporting and clamping devices; when an automobile seat framework is produced, all parts are usually welded to an automobile framework, for example, an automobile headrest sleeve and other parts are welded to an automobile framework; and the positioning of the positioning tool is troublesome. According to the welding device, during positioning, the framework only needs to be placed on four lower positioning blocks; then clamping air cylinders extend to drive pressing rods to press downwards; the framework is clamped by upper positioning blocks and the lower positioning blocks, so that pre-positioning can be completed; and during feeding of the sleeve positioning and feeding device, a pneumatic expansion sleeve only needs to be sleeved with a sleeve, so that automatic positioning can be achieved, and a pre-welding position can be reached; the front end fixing device and the rear end fixing device finish final positioning, so that the positioning accuracy is improved, and the welding quality is improved; and the framework can rotate along with the servo turntable, and welding of other positions is facilitated.

Description

technical field [0001] The invention relates to the field of automobile component manufacturing, in particular to a welding device for automobile seats. Background technique [0002] The car seat is composed of a car seat frame and a skin wrapped around the car seat frame, and the car seat frame mainly supports the seat. [0003] The car seat frame usually needs to be welded to the car frame during production, such as the car headrest sleeve and some other parts are welded to the car frame, and the general frame needs to be positioned and fixed during welding. The existing positioning is generally Set up multiple positioning and clamping tools on one positioning plate. This kind of positioning tooling is more troublesome when positioning, and it takes a long time to prepare for positioning, and it is difficult to adjust the position of the car frame once it is positioned, especially on the car frame. After the front side welding is completed, it is difficult to weld the bac...

[0003] The car seat frame usually needs to be welded to the car frame during production, such as the car headrest sleeve and some other parts are welded to the car frame, and the general frame needs to be positioned and fixed during welding. The existing positioning is generally Set up multiple positioning and clamping tools on one positioning plate. This kind of positioning tooling is more troublesome when positioning, and it takes a long time to prepare for positioning, and it is difficult to adjust the position of the car frame once it is positioned, especially on the car frame. After the front side welding is completed, it is difficult to weld the back side due to the narrow space, and sometimes it needs to be clamped and welded again in reverse

[0004] Secondly, when welding the car frame, it is usually necessary to weld the sleeve used to fix the headrest to the frame. The existing sleeve is troublesome for loading and positioning, and sometimes there will be positioning deviation, resulting in inaccurate welding position of the sleeve
