Description

Technical Field

[0001] This utility model relates to the field of bolt capacitor processing technology, and more specifically, to bolt capacitor riveting equipment. Background Technology

[0002] Bolted capacitors are electrolytic capacitors with bolted terminal connections. They feature high performance and high ripple resistance, and are mainly used in high-voltage, high-current applications such as uninterruptible power supplies and frequency converters. Bolted capacitors use metal bolts and insulating gaskets to form the electrode connection, and are suitable for high-voltage circuits from 400V to 700V, with capacitances exceeding 1000μF. During the manufacturing process of bolted capacitors, riveting equipment is required to secure the cap to achieve a sealed crimping effect. Traditional riveting equipment typically uses a transmission structure to drive the riveting head to rotate, thus tightening the connector.

[0003] However, when using this type of riveting equipment, the riveting head is mostly fixed by bolts, which means that tools are needed to replace or disassemble the riveting head, resulting in a slow disassembly speed and affecting the flexibility of the equipment during use.

[0004] Furthermore, traditional riveting equipment typically uses a one-piece clamping block, which makes it unsuitable for clamping different types of bolts and capacitors. Utility Model Content

When fixing the bolt container, the second motor 14 can be controlled to rotate the lead screw 13.
