Description

Technical Field

[0001] The utility model relates to the technical field of wire harness processing, in particular to a circumferential cutting device for air conditioner electrical wire harness processing. Background Technique

[0002] At present, during the use of the wire harness of an air conditioner electrical appliance, it is usually necessary to separate the outer wrapping cortex from the wire core for subsequent wire core connection. The wrapping cortex on the surface of the wire harness is usually cut off by a circumferential cutting device. In order to prevent damage to the insulation layer inside the wire harness, it is usually necessary to control the position of the cutting knife of the circumferential cutting device.

[0003] For example, the utility model with the patent number CN202021492918.X discloses a circumferential cutting device for electrical wire harness processing, including a cutting workbench, and a wire harness conveying unit is arranged above the cutting workbench. In this circumferential cutting device for electrical wire harness processing, two sets of telescopic tool holders can be telescopically adjusted inside the circumferential cutting cavity, and the circumferential cutting blades are installed at the ends of the telescopic tool holders. By adjusting the telescopic tool holders, the distance between the two sets of blades can be controlled. When cutting, the distance between the blades needs to be greater than the cortex thickness of the wire harness production specification, so as to avoid damaging the internal structure of the wire harness due to inaccurate cutting feed amount. At the same time, the gap needs to be controlled between 0.2 mm and 0.4 mm to avoid excessive thickness after cutting and the cortex cannot be separated from the wire harness. After completing the circumferential cutting work, the wire harness is clamped at one end by the wire stripping clamp on the fixed shaft rod, and the cut cortex is clamped at one end by the wire stripping clamp on the movable shaft rod. Then the movable shaft rod moves outward, and the cut cortex is separated from the wire harness body by the pulling force.

[0004] Although the circumferential cutting device in this patent can control the distance between the two sets of blades by adjusting the telescopic tool holders, it cannot clamp the wire harness on both sides of the cutting position. During the circumferential cutting process, the wire harness is prone to shift or bend, affecting the cutting accuracy. Summary of the Invention
