Accurate axial centering device for wire harness

Abstract

The invention discloses an accurate axial centering device for a wire harness. The accurate axial centering device is characterized in that a wire passing hole B is formed in the center of a supporting fixing plate; a clamping jaw seat is fixedly connected to the supporting fixing plate, a wire passing hole A is formed in the axis of the clamping jaw seat, and a plurality of radial sliding groovesA and a plurality of radial sliding grooves B are evenly formed in the upper portion of the clamping jaw seat in the circumferential direction; mechanical clamping jaws are slidably assembled in theradial sliding grooves A, and the middle portion and the left portion of the lower end of the mechanical clamping jaw are respectively connected with a longitudinal stop arm and a cam bearing follower; the longitudinal stop arm is connected with the inner end of the radial sliding groove B through a spring; a rotary sleeve is sleeved outside the clamping jaw seat through an axial cavity, and the inner side of the upper portion of the rotary sleeve is in rolling fit with the roller of a cam follower; a plurality of lift sliding grooves for allowing the roller to roll in and roll out are formedin the rotary sleeve in the circumferential direction; one end of the anticlockwise side of the lift sliding groove is provided with a guide inclined edge, and one end of the clockwise side of the lift sliding groove is provided with a limiting concave edge; and a cover plate is fixedly connected with the upper end of the clamping jaw seat through a connecting bolt. The accurate axial centering device can accurately position the axis of the wire harness, and can effectively reduce the labor cost.

Description

technical field [0001] The invention belongs to the technical field of wire harness processing, and in particular relates to a precise axial centering device for wire harnesses. Background technique [0002] In the wire harness processing industry, the outer diameter of the manufactured wire harness often has a certain error, and when the end face of the wire harness needs to be manufactured, it is easy to cause many quality risks in the manufacturing process. For example: when performing glue injection and waterproof treatment on the end surface of the automobile wire harness, the wire harness is usually fixed online. Due to the uncertainty of the outer diameter of the wire harness, this fixing method cannot accurately locate the axis of the wire harness, which will lead to glue injection. The unevenness will cause quality defects such as glue overflow on the surface of the wire. Due to the existence of such surface glue overflow, manual glue injection or mechanical glue i...

[0002] In the wire harness processing industry, the outer diameter of the manufactured wire harness often has a certain error, and when the end face of the wire harness needs to be manufactured, it is easy to cause many quality risks in the manufacturing process

For example: when performing glue injection and waterproof treatment on the end surface of the automobile wire harness, the wire harness is usually fixed online. Due to the uncertainty of the outer diameter of the wire harness, this fixing method cannot accurately locate the axis of the wire harness, which will lead to glue injection. The unevenness will cause quality defects such as overflow glue on the surface of the wire

Due to the existence of such surface glue overflow, manual glue injection or mechanical glue injection and manual cleaning are often used for glue injection operations. This method not only wastes a lot of manpower, but also has low production efficiency. At the same time, Product quality cannot be guaranteed
