Description

Technical Field

[0001] This utility model relates to the field of wire harness processing, and in particular to a moving mechanism for a wire harness terminal crimping machine. Background Technology

[0002] Wire harness terminals are key components in electrical connection systems, widely used in automobiles, electronic equipment, and home appliances to ensure reliable electrical contact between wires and equipment terminals. In traditional wire harness manufacturing, terminal crimping involves mechanically pressing metal terminals onto the exposed conductor portion of the wire to ensure conductivity and mechanical strength. With the development of industrial automation, manual crimping methods have been gradually replaced by crimping equipment due to their low efficiency and poor consistency.

[0003] Currently, mainstream terminal crimping equipment typically uses hydraulic or pneumatic drive mechanisms combined with a mold positioning system to complete the terminal crimping operation. The workflow involves holding the stripped cable, attaching the terminal, placing it in the designated position, and then the hydraulic press applies pressure to complete the crimping.

[0004] The operator must manually hold the cable steady until the hydraulic press completes the crimping action. This process not only increases the operator's workload but also carries the risk of crimping misalignment or incomplete connection due to human error. Furthermore, the hydraulic press has a long working cycle, requiring the operator to passively wait for the crimping to complete, significantly reducing production efficiency. Utility Model Content

The push plate extends out of the thin rod end of the placement frame and is provided with a directional component. The directional component is pressed and engaged with the second top plate. When the placement frame moves away from the pressing component, the directional component is used to push the push plate and eject the cable.

Detailed Implementation

[0023] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0024] Example: A moving mechanism for a wire harness terminal crimping machine, such as... Figures 1-3 As shown, the system includes an operating table 1, a crimping assembly 2, a base plate 3, an electric push rod 4, a moving plate 5, an electric slide rail 6, a placement rack 7, a clamping assembly, and a discharge assembly. The crimping assembly 2 is installed inside the operating table 1. The base plate 3 is connected to the front of the operating table 1. The electric push rod 4 is installed on the base plate 3. The top of the piston rod of the electric push rod 4 is connected to the moving plate 5. The electric slide rail 6 is installed inside the moving plate 5. The placement rack 7 is connected inside the electric slide rail 6. The electric slide rail 6 drives the placement rack 7 to slide back and forth. The moving plate 5 is equipped with a clamping assembly for automatically clamping cables. After the cables are crimped, the moving plate 5 is equipped with a discharge assembly for ejecting the cables.

[0025] like Figure 2 and Figure 3 As shown, the clamping assembly includes a first top plate 8, a first fixed seat 9, a pressure plate 10, and a first torsion spring 11. The first top plate 8 is connected to the movable plate 5. The first top plate 8 is located on the right side of the placement frame 7. The front end of the first top plate 8 is at the same height as the top of the placement frame 7. The rear end of the first top plate 8 is provided with a forward inclined surface, that is, the rear end of the first top plate 8 is higher than the placement frame 7. Several first fixed seats 9 are connected to the placement frame 7, and all the first fixed seats 9 are located on the right side of the placement frame 7. The pressure plate 10 is rotatably connected between the first fixed seats 9, and the two ends of the rotating shaft connecting the pressure plate 10 and the first fixed seat 9 are fitted with first torsion springs 11. One end of the first torsion spring 11 is connected to the first fixed seat 9, and the other end of the first torsion spring 11 is connected to the pressure plate 10.

[0026] like Figure 2 , Figure 4 and Figure 5 As shown, the discharge assembly includes a second top plate 12, a push plate 13, and a directional component 14. The second top plate 12 is connected to the moving plate 5. The second top plate 12 has inclined surfaces on both its front and rear sides. The top height of the second top plate 12 is lower than that of the placement frame 7. The push plate 13 is a wide plate that tilts to the right and is slidably connected to the placement frame 7. The push plate 13 extends out of the thin rod end of the placement frame 7 and is provided with a directional component 14. The directional component 14 is pressed and engaged with the second top plate 12. When the placement frame 7 moves away from the pressing assembly 2, the directional component 14 is used to push the push plate 13 and push out the cable. The push plate 13 extends towards the middle of the placement frame 7 with an auxiliary plate.

[0027] like Figure 5 As shown, the orientation assembly 14 includes a rotating plate 141, a second fixed seat 142, and a second torsion spring 143. The outer end of the thin rod of the push plate 13 is rotatably connected to the rotating plate 141. The top and bottom sides of the outer end of the push plate 13 are both connected to the second fixed seat 142. The rotating plate 141 and the aforementioned push plate 13 are fitted with the second torsion spring 143. One end of the second torsion spring 143 is connected to the rotating shaft of the rotating plate 141, and the other end is connected to the second fixed seat 142. The rotating plate 141 and the second top plate 12 are pressed together.

[0028] like Figure 3 As shown, it also includes a roller 15. The roller 15 is rotatably connected to one end of the pressure plate 10 facing the pressing assembly 2. The roller 15 is rotatably connected to the first top plate 8. The roller 15 rolls along the inclined surface at the rear end of the first top plate 8, converting sliding friction into rolling friction, significantly reducing the resistance when the pressure plate 10 rotates, and ensuring that the pressure plate 10 moves smoothly and without jamming when automatically clamping the cable.

[0029] like Figure 2As shown, it also includes a rubber pad 16. A rubber pad 16 is provided on the top surface of the placement frame 7, and a rubber pad 16 is provided on one side of the pressure plate 10 and the cable. This not only prevents the cable insulation layer from being damaged during clamping, but also counteracts the axial movement during crimping through friction, ensuring the relative position of the cable and the terminal is stable.

[0030] like Figure 1 As shown, it also includes a collection box 17. The left side of the base plate 3 is connected to the collection box 17 to avoid manually picking up the pressed finished products one by one.

[0031] like Figure 1 As shown, it also includes a guide plate 18. The left end of the movable plate 5 is connected to the guide plate 18. Through the combined effect of gravity and inclined plane guidance, the cable slides into the collection box 17 in a controlled posture.

[0032] The electric push rod 4 pushes the moving plate 5 upward, and the groove in the middle of the placement rack 7 is higher than the groove of the crimping assembly 2 where the cable is placed. The electric slide rail 6 drives the placement rack 7 forward, and the pressure plate 10 is perpendicular to the right side of the placement rack 7. The orientation assembly 14 is located in front of the second top plate 12. At this time, the operator places the cable with the terminal sleeve on the placement rack 7, and the terminal is fully extended out of the placement rack 7. Only the cable is in contact with the rubber pad 16 on the placement rack 7. Then the electric slide rail 6 drives the placement rack 7 to move backward. At this time, the cable and the terminal are higher than the crimping groove of the crimping assembly 2. When the placement rack 7 moves to the rear end of the electric slide rail 6, the connection between the terminal and the cable is located in the middle of the crimping assembly 2. At this time, the electric push rod 4 pulls the moving plate 5 down to place the terminal on the crimping assembly 2. Then the crimping assembly 2 is activated to complete the crimping of the cable terminal. After the crimping assembly 2 releases the terminal, the electric push rod 4 pushes the moving plate 5 upward. After the cable is separated from the crimping assembly 2, the electric slide rail 6 drives the placement rack 7 to return to its original position.

[0033] As the electric slide rail 6 drives the placement rack 7 to move backward, the placement rack 7 drives the push plate 13 to move backward. The rotating plate 141 rotates around the end of the push plate 13 under the pressure of the second top plate 12, and twists the second torsion spring 143. After the rotating plate 141 is separated from the second top plate 12, the second torsion spring 143 twists back to make the rotating plate 141 rotate back to its original position. The pressure plate 10 is pressed and cooperated with the first top plate 8 through the roller 15. When it passes through the inclined surface of the rear end of the first top plate 8, the first top plate 8 pushes the pressure plate 10 to rotate around the first fixed seat 9, and twists the first torsion spring 11. Finally, the pressure plate 10 rotates 90 degrees and is fastened on the placement rack 7 to complete the clamping and fixing of the cable. The rubber pad 16 provides flexible clamping force through elastic deformation to ensure the stability of the cable fixing by the placement rack 7 and the pressure plate 10. The rear end limiting structure of the crimping assembly 2 limits the distance of the terminal extending backward.

[0034] After the crimping is completed, the electric slide rail 6 drives the placement rack 7 to move forward. The placement rack 7 also drives the push plate 13 to move forward. At this time, the rotating plate 141 is pressed against the second top plate 12. However, the push plate 13 on the back side of the rotating plate 141 restricts it, so the rotating plate 141 cannot rotate backward. The rotating plate 141 slides upward along the inclined surface of the second top plate 12, thereby driving the push plate 13 to slide upward and pushing the crimped cable to roll to the right. The rolled-down cable enters the collection box 17 after being guided by the guide plate 18. At this time, the placement rack 7 slides forward to reset. The staff puts the cable to be crimped on the placement rack 7. Generally, both ends of the cable need to be connected to terminals. The staff takes out the cable that has been crimped at one end from the collection box 17, turns it around and puts it back on the placement rack 7 to perform the other end crimping operation, thus completing the crimping of both ends.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
