The side wall clamping mechanism 10 is provided with an A column clamping unit 500 and a B column clamping unit 100, and the A column clamping unit 500 and the B column clamping unit 100 are positioned on the side wall conveying trolley 20; and a first driving unit 300 that drives the a-column clamping unit 500 and the B-column clamping unit 100 to move in the X-axis direction; and a second driving unit 400 driving the B-pillar clamping unit 100 to move in the Y-axis direction. When the side wall conveying trolley 20 conveys the automobile side wall 30, the A column clamping unit 500 and the B column clamping unit 100 are separated from the first driving unit 300 and the second driving unit 400.
Therefore, when the automobile side wall 30 is preassembled on the side wall conveying trolley 20, the side wall conveying trolley 20 provides Z-direction support for the automobile side wall 30, at this time, the a-pillar clamping points of the automobile side walls 30 of different models need to be adjusted at the same position, that is, the automobile side walls 30 of different models share one a-pillar clamping point, and are positioned and clamped by the a-pillar clamping unit 500. At this time, the B pillar clamping unit 100 is only needed to clamp the B pillar clamping points of the automobile side walls 30 of different vehicle types, and the B pillar clamping unit 100 adjusts the X-direction and Y-direction positioning through the first driving unit 300 and the second driving unit 400 to complete the positioning of the automobile side walls 30 of different vehicle types. The clamping and conveying of the automobile side walls 30 of different automobile types can be realized, the problem that the traditional single automobile type conveying line is frequently replaced along with the updating of the automobile type is solved, the cost of the whole automobile is reduced, and the market competitiveness of the automobile is improved.
