[0002] The electric energy metering box is generally mainly welded by thin steel plates, and heat deformation is easily generated in the welding process, so that the key size of the box body is out of tolerance. Artificial positioning cannot guarantee the precision and consistency, and seriously affects the installation precision, sealing performance and protection level of the subsequent expensive metering equipment and components, and therefore, a special tool is needed to overcome the problems of thin plate welding deformation and inaccurate positioning.

[0003] The metering box has a large demand and a high production batch. The traditional method of relying on artificial marking, alignment and deformation correction after welding is low in efficiency, high in cost and unstable in quality, and becomes a bottleneck of production capacity. The positioning device is designed to realize rapid and accurate positioning and reliable clamping of the workpiece, significantly shorten the single piece welding time, reduce the rework and scrap, reduce the dependence on high-skilled welders, and greatly improve the production efficiency and reduce the comprehensive manufacturing cost.

[0004] The metering box must ensure that the components such as electric meters are installed stably and wired reliably, and the structural precision is the basis for the metering accuracy and long-term operation safety. The positioning device strictly controls the welding deformation and guarantees the size consistency, provides key process guarantee for meeting the strict electrical safety distance, protection level requirements and product standardization and interchangeability, and finally improves the overall quality and market competitiveness of the product.

[0005] Based on this, the positioning device for welding an electric energy metering box is proposed. SUMMARY
