Description

Technical Field

[0001] The utility model relates to the technical field of production of connecting wire harnesses, in particular to an end wire stripping device for automotive connecting wires. Background Art

[0002] An automotive wire harness is the network main body of an automotive circuit. Without a wire harness, there would be no automotive circuit. A wire harness refers to a component formed by crimping contact terminals (connectors) made of copper material with wires and cables, and then externally molding an insulator or adding a metal shell, etc., and bundling the wire harness to form a connection circuit. The body wire harness connects the entire body, and generally has an H shape. The wire harness industry chain includes wire and cable, connectors, processing equipment, wire harness manufacturing, and downstream application industries. The wire harness has a very wide range of applications and can be used in automobiles, household appliances, computers and communication equipment, various electronic instruments and meters, etc.

[0003] When producing a connecting wire harness, it is necessary to use cold pressing or hot welding methods to connect the end of the connecting wire harness with an external terminal block. Before that, it is necessary to perform wire stripping processing on the end of the connecting wire harness to expose the metal wire at the end of the connecting wire harness. Based on this, an end wire stripping device for connecting wires is proposed, which is used for batch wire stripping processing of connecting wire harnesses. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an end wire stripping device for automotive connecting wires, effectively solving the deficiencies of the prior art.

[0005] To achieve the above purpose, an embodiment of one aspect of the utility model provides an end wire stripping device for automotive connecting wires, including a bottom plate. Vertically placed vertical support frames and two mounting frames are respectively installed on the top surface of the bottom plate. The top and bottom of one side of the vertical support frame are respectively installed with an upper moving frame and a lower moving frame that can move vertically, and cutting knives are installed between the adjacent outer walls of the two. The middle parts of the two mounting frames are hollowed out, and rotatable top push rods are respectively installed inside them. Limiting grooves are respectively opened on one side of the two top push rods, and connecting shafts are installed inside both of them. One ends of the two connecting shafts are respectively fixedly connected to two corners of the lower moving frame. Support legs are respectively installed on both sides of the bottom surface of the upper moving frame. The bottom ends of the two support legs are respectively installed with rollers, and the two rollers are in rolling connection with one side of the two top push rods. A wire placing seat is installed at the top of the two mounting frames.

[0006] Preferably, according to any of the above solutions, a slantingly placed reinforcing rod is installed between one side of the vertical support frame and the bottom plate. A pneumatic cylinder is installed on the top surface of the vertical support frame, and its output end is fixedly connected to the top surface of the upper moving frame. The reinforcing rod in this solution facilitates the stable support of one side of the vertical support frame and improves its structural strength. At the same time, the pneumatic cylinder is installed at the top of the vertical support frame. Through its own extension or shortening action, it facilitates driving the upper moving frame and the lower moving frame to move synchronously, so as to cut off the insulating skin of the wire by two cutting knives.

[0007] Preferably, according to any of the above solutions, two guide rails are installed at both the top end and the bottom end of one side of the vertical support frame. The four guide rails are grouped in pairs. One side of the upper moving frame and the lower moving frame are respectively slidably connected to the two guide rails. Using this solution facilitates guiding the movement of the upper moving frame and the lower moving frame, making the two cutting knives align with each other and avoiding dislocation. The vertical support frame is vertically placed and is perpendicular to the bottom plate, providing an installation position for the four guide rails. Then, through the extension action of the pneumatic cylinder, the upper moving frame and the lower moving frame are pushed to move towards each other, and the insulating skin of the wire is cut off by the two cutting knives.

[0008] Preferably, according to any of the above solutions, tension springs are arranged between both sides of the bottom surface of the lower moving frame and the bottom plate. Using this solution facilitates pulling the lower moving frame. After the pneumatic cylinder shortens, it drives the upper moving frame to rise a certain height, and at the same time, the two support legs rise synchronously. The two tension springs pull the lower moving frame downward, so that the two cutting knives move away from each other, facilitating the preparation for cutting the insulating skin of the wire next time.

[0009] Preferably, according to any of the above solutions, rectangular tubes are arranged on both sides of the bottom surface of the upper moving frame. The top ends of the two support legs are respectively fixedly connected to the two rectangular tubes by bolts. Using this solution facilitates providing an installation position for the two support legs. At the same time, adopting the shape of rectangular tubes can prevent relative rotation between the two support legs and the bottom end of the upper moving frame, making the two rollers stably contact the two top push rods.

[0010] Preferably, according to any of the above solutions, the two wire placement seats are located on both sides of the cutting knife. Arc-shaped blocks are arranged on the opposite sides of the two wire placement seats. Using this solution facilitates providing a placement position for the wire. At the same time, using two wire placement seats enables the wire to be vertically placed relative to the cutting knife, facilitating the subsequent cutting of the insulating skin. The cutting knife adopts a concave structure near the battery cell to avoid scratching the battery cell.

Detailed implementation mode

[0022] The following further describes the present utility model in conjunction with the accompanying drawings, but the protection scope of the present utility model is not limited to the following description.

[0023] As Figures 1 to 7 shown, an end wire stripping device for an automotive connecting wire includes a bottom plate 1. A vertically placed vertical support frame 9 and two mounting frames 15 are respectively installed on the top surface of the bottom plate 1.

Limiting grooves 14 are respectively opened on one side of the two push rods 5, and connecting shafts 3 are installed inside both of them. One ends of the two connecting shafts 3 are respectively fixedly connected to the two corners of the movable lower frame 2. Support legs 6 are respectively installed on both sides of the bottom surface of the movable upper frame 11. Roller wheels 16 are installed at the bottom ends of the two support legs 6.

[0024] An inclined strengthening rod is installed between one side of the vertical support frame 9 and the bottom plate 1. An air cylinder 8 is installed on the top surface of the vertical support frame 9, and its output end is fixedly connected to the top surface of the movable upper frame 11. As an alternative technical solution of the present utility model, the strengthening rod facilitates the stable support of one side of the vertical support frame 9 and improves its structural strength. At the same time, the air cylinder 8 is installed at the top of the vertical support frame 9. Through its own extension or shortening action, it is convenient to drive the movable upper frame 11 and the movable lower frame 2 to move synchronously, so as to realize the cutting of the insulating skin of the wire by the two cutting knives 7.

The position of the cutting knife 7 close to the battery core adopts a concave structure to prevent it from scratching the battery core.

[0029] The end wire stripping device of the automotive connecting wire requires the following steps during use:

[0030] 1) During use, separate the wires of the wire harness and place them on the two wire placement seats 12 respectively;

[0031] 2) The pneumatic cylinder 8 extends, pushing the upper moving frame 11 to descend in height, and at the same time, the two support legs 6 push one end of the two ejector rods 5;

[0033] 4) The upper moving frame 11 and the lower moving frame 2 push the two cutting knives 7 to cut the insulating skin of the wire;

[0034] 5) Pull the wire harness outwards to complete the wire stripping.

[0035] In summary, when the user is using it, by setting two mounting brackets 15, and there are two wire placement seats 12 provided at the tops of both of them. At the same time, an upward moving bracket 11 and a lower mounting bracket 2 that move vertically are installed on one side of the vertical support frame 9.
