Welding tool for production of automobile seat framework

Abstract

The invention discloses a welding tool for production of an automobile seat framework. The welding tool for production of the automobile seat framework comprises a base (1), a feed clamping device, two side section clamping devices and a supporting bar clamping device, wherein the feed clamping device is provided with a sleeve (14) in advance and pushes the sleeve to the position above a slope (50) of the bottom section of a U-shaped bent pipe (2) in the automobile seat framework, the two side section clamping devices are used for fixedly clamping two side sections of the U-shaped bent pipe (2), and the supporting bar clamping device is used for fixedly clamping a first supporting bar (3) and a second supporting bar (4) so that the two ends of the first supporting bar (3) and the two ends of the second supporting bar (4) can be in fixed lap joint to the two side sections of the U-shaped bent pipe (2) correspondingly. By the adoption of the structure, the U-shaped bent pipe, the first supporting bar and the second supporting bar can be fixedly clamped, and therefore the welding tool for production of the automobile seat framework can guarantee fixed clamping of the U-shaped bent pipe and the welding precision and the product consistency of the first supporting bar and the second supporting bar during automatic welding.

Description

technical field [0001] The invention relates to the technical field of car seats, in particular to a welding tool for producing car seat frames. Background technique [0002] The car seat includes a car seat frame and a leather cushion wrapped outside the car seat frame, and the car seat frame mainly supports the seat. [0003] Such as figure 1 The base of the car seat frame generally includes a U-shaped bend 2, a first support bar 3, a second support bar 4 and a sleeve 14, the bottom of the U-shaped bend 2 is the bottom section, and the two ends of the U-shaped bend 2 The side is the side section, and an inclined plane 50 is punched on the bottom section of the U-shaped elbow 2, the sleeve 14 is welded on the inclined plane 50, and the two ends of the first support bar 3 and the second support bar 4 are respectively welded to the two ends of the U-shaped elbow 2. In this way, to increase the structural strength of the U-shaped elbow 2 and to support the cushions. [0004...

AI Technical Summary

Problems solved by technology

In this way, there will be some disadvantages: 1. The positions of the first support bar, the second support bar, and the casing are different due to the operators, and the product consistency cannot be guaranteed; 2. In the welding process, the first support bar, the second support bar, and the 2. The support bars and sleeves are easy to move relative to the U-shaped bend, which will affect the welding accuracy and welding firmness; 3. Manual welding, the welding efficiency is low
