The manufacturing process for bearing cages generally includes welding the interfaces at both ends of the cage. With the continuous development of the industry, traditional stamping and welding processes can no longer meet production requirements. With the continuous advancement of automatic welding equipment, the mechanization and automation of the stamping and welding production process is an inevitable trend in the industry. When using automatic welding equipment, the workpiece must first be mounted on a tooling platform to meet the operating environment of the automatic welding equipment and maintain its operation.

After the first clamping part and the second clamping part clamp the bearing retainer, a welding port is left at the butt joint between the two, so that the welding equipment can weld the interfaces at both ends of the bearing retainer. The supporting mold has a welding groove at the position corresponding to the welding port to avoid connection during welding and to heat dissipate. During the entire welding process, the supporting mold and the clamping mold fit tightly to the inner and outer sides of the bearing retainer, with stable positioning and no offset of the welding point. However, only bearings of fixed size can be positioned between the first clamping part and the second clamping part, and the applicability is general.
