Description

Auxiliary positioning device for wire harness crimping machine

Technical Field

The utility model relates to the technical field of wire harness crimping machines, in particular to an auxiliary positioning device of a wire harness crimping machine.

Background Art

The wire harness crimping machine is an important equipment for wire harness crimping in the electric power field. Through the wire harness crimping machine, the wire harnesses can be connected.

After searching, according to the patent number "CN216850695U", an auxiliary positioning device for a wire harness crimping machine is disclosed, including a base, a crimping tool and a crimping tool seat. The top end surface of the base is provided with a slide groove for the crimping tool seat to slide up and down. The bottom of the crimping tool seat is provided with a buffer assembly, and the buffer assembly includes a guide rod provided at the bottom of the crimping tool seat and a spring sleeved on the guide rod. By sliding the crimping tool seat in the slide groove, and providing a guide rod at the bottom of the crimping tool seat, and a spring sleeved on the guide rod, the crimping tool seat and the crimping tool can obtain a buffer force when crimping the wire harness before rigid crimping, so that the clamping connection between the terminal and the wire is more stable, and the quality of the wire harness is improved.
