The riveted joints have good appearance quality and will not have a significant impact on the appearance of the car body. At the same time, riveting technology can also reduce the heat-affected zone and deformation that may occur during the welding process, further improving the overall quality of the car body.

[0003] A Chinese patent discloses a vehicle body positioning device (publication number CN202754762U). The patent includes a base with symmetrical support structures fixed on both sides of the base. The top surface of the support structure is provided with four clamping mechanisms for supporting and clamping the vehicle body, and the four clamping mechanisms are opposite each other. The support structure includes a vertical frame erected vertically and a horizontal frame fixed to the vertical frame, and the four clamping mechanisms are arranged on the horizontal frame. A drive mechanism for moving the horizontal frame up and down is also provided, including a motor, a chain wheel, two inner guide rails, a counterweight block, a chain, a first guide wheel, a second guide wheel, and a third guide wheel. A limit sensor and a precision limit sensor are also provided for sensing the position of the horizontal frame.

[0004] Therefore, based on the above search and in combination with the existing ones, since the car body is large in size and thin in thickness, it is easy to deform. When the above device clamps the car body, the car body parts may become loose due to the small contact range. However, in order to increase the fixing effect, when the above device excessively clamps the car body, the car body will be deformed due to insufficient rigidity and weak deformation resistance, and secondary processing and correction are required. Therefore, the utility model provides a riveting positioning device for automobile body-in-white to solve the above-mentioned problems. Utility Model Content
