Description

Technical Field

[0001] This utility model relates to the technical field of automotive wiring harness processing equipment, and in particular to a polygonal shielding mesh opening and folding mechanism. Background Technology

[0002] Shielded cables mainly consist of four parts: conductor, insulation layer, shielding layer, and sheath. The conductor carries the current, the insulation layer protects the conductor (the insulation layer includes outer insulation and inner insulation), the shielding layer suppresses electromagnetic interference, and the sheath protects the cable as a whole. To install electrical connectors at the ends of a shielded cable, it is necessary to remove the outer insulation surrounding the shielding layer and then push the end of the shielding layer back by a predetermined length in a direction substantially perpendicular to the extension direction of the inner conductor, while simultaneously widening (expanding) it. Currently, this has been achieved by injecting a compressed air jet between the inner insulation and the braided shield.

[0003] An existing Chinese patent, CN106402101B, discloses a cable clamping device for widening cable braided shielding, comprising at least two clamping bodies configured to form a channel completely surrounded by them, wherein the clamping bodies are slidable relative to each other to change the circumference of the channel.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following problems exist: In actual use, the adjacent clamping bodies must slide and fit together and limit each other to ensure that the movement of several clamping bodies is the same and that the force in all directions is uniform when the clamping bodies clamp the cable. However, due to the sliding and fitting between adjacent clamping bodies, friction loss is inevitable. Over time, this can easily affect the limiting effect between adjacent clamping bodies, change the amount of movement of the clamping bodies, and cause uneven pressure when the clamping bodies clamp the cable, thus affecting the clamping and widening effect of the clamping bodies on the shielding layer. Utility Model Content

[0038] The implementation principle of the polygonal shielding mesh opening and folding mechanism in this application embodiment is as follows: Before operation, the wire harness to be processed is fixed outside the wire harness channel by an external clamping device, and a flange is pressed on the front end of the wire harness to be processed. The diameter of the flange is smaller than the diameter of the second folding tube 610. During operation, the first base plate 11 is driven by the electric servo slide rail to move towards the wire harness to be processed, so that the wire harness to be processed enters the wire harness channel and is located between the six clamping bodies 4. The clamping bodies 4 are located in front of the flange on the wire harness. Then, the drive motor 51 and the reducer 52 drive the drive gear 53 to rotate. The drive gear 53 drives the driven gear 54 and the turntable to rotate. The turntable passes through the drive groove 55. 1. The second limiting post 43 moves within the slide groove 331, and the drive groove 551 defines the first direction of movement of the second limiting post 43. At this time, the first limiting post 42 and the second limiting post 43 both move within a groove on the side of the slide groove 331, which defines the second direction of movement of the first limiting post 42 and the second limiting post 43. Through the defined first and second directions of movement, the drive assembly 5 can more accurately define the direction of movement of the clamping body 4. Adjacent clamping bodies 4 do not need to slide against each other for positioning, thereby driving the clamping body 4 to move and clamp the wire harness shielding mesh in a ring manner, causing the wire harness shielding mesh to slightly open in a funnel shape due to compression deformation. Next, the clamping body 4 opens, and the first base plate 11 continues to move, driven by the electric servo slide rail, so that the clamping body 4 is at the rear end of the flange on the wire harness. Then, the clamping body 4 clamps and fixes the wire harness. Then, the first push cylinder 601 pushes the first connecting plate 6011 and the first slider 604 to move toward the wire harness. Then, the second push cylinder 602 pushes the second connecting plate 6022 and the second slider 606 to move toward the wire harness. The second slider 606 drives the mounting shell 607 to move together, so that the second folding tube 610 passes through the outer side of the inner insulation layer of the wire harness. At the same time, the air nozzle 614 delivers gas into the first folding tube 608 and the second folding tube 610. The gas is discharged from the second folding tube. The tube 610 enters between the inner insulation layer and the shielding layer to facilitate better separation of the inner insulation layer and the shielding layer. When the second folding tube 610 moves to the root of the shielding layer, that is, when it abuts against the flange, the second folding tube 610 stops moving due to the presence of the compression spring 613. The first folding tube 608 continues to move along the outside of the second folding tube 610 until the second folding tube 610 is completely retracted into the first folding tube 608. Then, the first folding tube 608 passes over the flange and continues to fold the shielding layer until the shielding layer is folded at a certain degree, thus completing the folding. When taking out the processed wire harness, high-pressure gas is introduced into the wire harness channel by the high-pressure gas nozzle 813 to prevent the shielding mesh from sticking to the clamping body 4.
