Description

Technical Field

[0001] This application relates to the field of wire harness processing, and particularly to a wire harness processing crimping device. Background Technique

[0002] Wire harness processing refers to the process of peeling, cutting, welding, insulating, and assembling components such as wires, cables, or connectors according to design requirements. This processing is usually used for manufacturing the electrical connection parts in products such as automobiles, electronic devices, aerospace aircraft, and household appliances. Wire harness crimping processing refers to the process of firmly connecting a wire or cable to a connector terminal by using a crimping tool with mechanical force.

[0003] During the crimping process, for wire harnesses of different sizes and types, different models of connector terminals are used. When crimping, different models of crimping parts need to be replaced to squeeze the connector terminals. However, it is rather inconvenient to repeatedly disassemble and assemble the crimping parts during replacement. Moreover, the crimped connector terminals may get stuck in the crimping parts, thus affecting the removal of the connector terminals after crimping and reducing the overall processing efficiency of the wire harness.

[0004] Regarding the above related technologies, the inventor believes that there are defects in the inconvenient repeated disassembly and replacement of connector terminals during wire harness processing. Therefore, a wire harness processing crimping device is proposed to solve the above problems. Utility Model Content

On both upper and lower ends of one side of the support frame, fixing plates are welded. One end edge of the fixing plate is welded with a fixing rod. A spring is sleeved on the outer surface of the fixing rod at one end of the fixing plate. A sliding mechanism is further provided on the outer surface of the support frame for adjusting the movement of the movable frame.

[0008] Preferably, the sliding mechanism includes a sliding groove symmetrically formed in the middle of one end of the inner wall of the support frame. A limiting rod is welded to one side edge of the movable frame. A cylinder is installed on the other side of the support frame, and a limiting plate is fixedly connected to the output end on one side of the cylinder. Guide grooves are symmetrically formed at one end of the limiting plate, and one end of the limiting rod passes through the sliding groove and is placed inside the guide groove.

[0009] Preferably, a groove is formed at a position corresponding to the fixing groove on the outer surface of the mounting plate. One side of the outer surface of the fastening bolt is located in the groove, and the fastening bolt and the groove are engaged with each other.

One end of the mounting plate 4 is fixedly installed with a crimping member 5. At both front and rear ends on one side of the connecting plate 3, fixing grooves 6 are symmetrically opened. Inside the fixing grooves 6, fastening bolts 7 are rotatably installed. At the corresponding position on the outer surface of the mounting plate 4, a groove is opened. One side of the outer surface of the fastening bolt 7 is located in the groove, and the fastening bolt 7 and the groove are engaged with each other. One side of the outer surface of the fastening bolt 7 is placed at one end of the mounting plate 4 and is threadedly connected with a fastening nut 8. One end of the inner wall of the crimping member 5 passes through the connecting plate 3 and is provided with a through hole 9. At both upper and lower ends on one side of the support frame 1, fixing plates 10 are welded. One end edge of the fixing plate 10 is welded with a fixing rod 11. The outer diameter of the fixing rod 11 is smaller than the inner diameter of the through hole 9. One end edge of the fixing rod 11 extends into the through hole 9. The through hole 9 and the fixing rod 11 are coupled with each other. One end of the fixing plate 10 is sleeved with a spring 12 on the outer surface of the fixing rod 11. A sliding mechanism is further provided on the outer surface of the support frame 1 for adjusting the movement of the movable frame 2.

[0021] By placing the mounting plate 4 at the edge of the outer surface of the connecting plate 3, aligning the positions of the fixing groove 6 and the groove, rotating the fastening bolt 7 to be engaged in the groove, rotating the fastening nut 8 to be threadedly connected to the outer surface of the fastening bolt 7, and making the fastening nut 8 abut against the upper surface of the mounting plate 4, multiple fastening bolts 7 cooperate with the fastening nuts 8 to fix the mounting plate 4 on the connecting plate 3, which helps to conveniently disassemble and assemble the crimping member 5. At the same time, the two crimping members 5 after crimping are separated from each other, the two connecting plates 3 are separated and moved, and the fixing rod 11 is inserted into the moving through hole 9, so that the fixing rod 11 pushes out the wire harness terminal stuck in the crimping member 5, and the spring 12 buffers and supports the moving connecting plate 3 to keep the connecting plate 3 in a stable moving state, reflecting the overall installation and fixing effect of the crimping member 5.

[0022] Refer to Figure 1 and Figure 2, the sliding mechanism includes a sliding groove 13 symmetrically opened at the middle of one end of the inner wall of the support frame 1. A limiting rod 14 is welded to the edge of one end of the movable frame 2. A cylinder 16 is installed on the other side edge of the support frame 1. A limiting plate 17 is fixedly connected to the output end on one side of the cylinder 16. Guide grooves 18 are symmetrically opened at one end of the limiting plate 17. One end of the limiting rod 14 passes through the sliding groove 13 and is placed inside the guide groove 18. Fixed guide rails 15 are symmetrically arranged at the edge of the front end surface of the support frame 1. The upper and lower edges of the limiting plate 17 are respectively located inside the fixed guide rails 15, and the fixed guide rails 15 and the limiting plate 17 are mutually fitted.

[0023] By starting the cylinder 16 to push the limiting plate 17 to move along the inside of the fixed guide rail 15, the limiting plate 17 drives the limiting rod 14 to move along the inside of the guide groove 18, and at the same time makes the limiting rod 14 move along the inside of the sliding groove 13, thereby enabling the limiting rod 14 to adjust the distance between the two movable frames 2. Place the wire harness terminal in the crimping member 5, and make the mutually approaching crimping members 5 crimp the wire harness terminal, reflecting the extrusion effect of the wire harness terminal in the crimping member 5.

At the same time, start the cylinder 16 to push the limiting plate 17 to move along the inside of the fixed guide rail 15. The input end of the power supply of the cylinder 16 is electrically connected to the output end of the external power supply, so that the limiting plate 17 drives the limiting rod 14 to move along the inside of the guide groove 18, and at the same time makes the limiting rod 14 move along the inside of the sliding groove 13, thereby enabling the limiting rod 14 to adjust the distance between the two movable frames 2. Place the wire harness terminal in the crimping member 5, and make the mutually approaching crimping members 5 crimp the wire harness terminal. After crimping, the two crimping members 5 are separated from each other, and at the same time, the two connecting plates 3 are separated and moved, and the fixing rod 11 is inserted into the through hole 9 in the movement, so that the fixing rod 11 ejects the wire harness terminal stuck in the crimping member 5, and the spring 12 buffers and supports the moving connecting plate 3 to keep the connecting plate 3 in a stable moving state; compared with the prior art, this solution has the effect of facilitating the convenient disassembly, replacement and installation of the crimping member 5, improves the overall installation effect of the crimping member 5, solves the problem that the wire harness terminal is not easy to take out when stuck in the crimping member 5, and reflects the ejection effect of the fixing rod 11 on the wire harness terminal after crimping in the crimping member 5.
