Abstract

The invention relates to the technical field of feeding devices, in particular to a rotating wheel type feeding device applied to high-voltage wire harness terminal electromagnetic pulse welding, which comprises a support column, a rotating disc is arranged on the support column, a conveying mechanism is arranged on the rotating disc, and the conveying mechanism comprises a first conveying arm and a second conveying arm. High-voltage wire harness limiting holes are formed in the first conveying arm and the second conveying arm correspondingly, terminal hole positions are installed at the ends, away from each other, of the first conveying arm and the second conveying arm correspondingly, the high-voltage wire harness limiting holes are arc-shaped, and a driving mechanism for driving the first conveying arm and the second conveying arm to move synchronously is arranged on the rotating disc. According to the rotating wheel type feeding device applied to electromagnetic pulse welding of the high-voltage wiring harness terminal, the situation that due to the fact that pressure exists in the horizontal direction, a high-voltage wiring harness moves backwards in the welding process, the mechanical performance and the electrical performance of a connector are reduced can be avoided, and the final welding effect is ensured.

Description

technical field [0001] The invention relates to the technical field of feeding devices, in particular to a runner-type feeding device applied to electromagnetic pulse welding of high-voltage wire harness terminals. Background technique [0002] The connection between the high-voltage wire harness and the terminal is very important. The connection quality determines the mechanical and electrical properties of the joint. When the material of the terminal and the high-voltage wire harness is different, the traditional crimping method is limited by the physical properties of the material, mechanical technology, It is difficult to ensure the reliable crimping of the joint due to factors such as the experience of technicians. For example, when the copper terminal is crimped with the aluminum alloy wire harness, due to the soft texture of the aluminum alloy, the wire harness is seriously deformed, and it is prone to loosening during its long-term service, reducing the joint’s reliab...

Problems solved by technology

[0003] However, during the electromagnetic pulse welding process, due to the distribution of electromagnetic force and deformation resistance, the terminal and the high-voltage wire harness are deformed rapidly at a certain angle and collide with each other. Because of the angle, there is pressure in the horizontal direction, resulting in the high-voltage wire harness being in the welding process. Moving backwards (away from the terminals) degrades the mechanical and electrical properties of the connector
