Description

Technical Field

[0001] The utility model relates to the technical field of wire harness production, and more specifically, to a wire harness terminal crimping mechanism. Background Art

[0002] In modern industrial production, wire harness terminal crimping is a crucial technological process, especially playing a vital role in fields such as electronics, electrical, communication, and automotive. Wire harness terminal crimping refers to the process of connecting wires or cables to terminals through mechanical pressure to achieve the effective transmission of electrical signals or electrical energy.

[0003] In the prior art, usually, a worker puts the terminal on the wire harness, places the sleeved terminal in the die, and then starts the crimping machine to press and connect the terminal and the wire harness together. However, during the crimping process, the worker needs to hold the wire harness terminal by hand, so the worker's hand is easily injured during crimping, forming a certain safety hazard.

[0004] After retrieval, a Chinese patent with the publication number CN219498451U discloses a wire harness terminal crimping mechanism for automobiles. This structure uses a driving motor to drive a reciprocating screw to rotate, making the moving block drive the connecting rod to move, pushing the movable rod to slide in the chute, so that the push block pushes the terminal towards the die. At the same time, an electric push rod pushes the rectangular block to slide in the rectangular groove, making the wire harness approach the terminal, thereby sleeving the terminal on the wire harness, reducing the operation of the worker's hand, and thus reducing the probability of being injured.

[0005] However, when this structure is actually used, when crimping the wire harness, it is necessary to place the terminal inside the chute and move the terminal through the push block. However, the sizes of the terminals corresponding to different wire harnesses are different, and the size of the chute of this structure is fixed, making it difficult to stably transport terminals of different sizes, resulting in the terminals shifting during the movement inside the chute, ultimately affecting the crimping effect of the wire harness terminals. In view of this, the present utility model proposes a wire harness terminal crimping mechanism. Summary of the Utility Model

[0025] Specifically, in this structure, the wire harness terminals can be placed inside the arc-shaped groove 3 opened on the surface of the crimping seat 2.

After one end of the wire harness is docked with the terminal, the first electric push rod 7 drives the movable plate 6 to extend downward, so that the crimping block 8 extends into the arc-shaped groove 3, thereby crimping the wire harness and the terminal.

[0026] In a specific embodiment, as shown in the attached Figure 1 、 2 、3, a plurality of adaptive clamping structures are provided on both inner walls of the arc-shaped groove 3 opened on the crimping seat 2. The adaptive clamping structure includes a movable block 9. A movable cavity 10 is opened on the inner wall of the arc-shaped groove 3.

A compression spring 11 is installed inside the movable cavity 10, and both ends of the compression spring 11 are respectively connected to the inner wall of the movable cavity 10 and one end of the movable block 9. A circular groove 12 is opened on the surface of the movable block 9. A ball 13 is embedded and rotatably installed inside the circular groove 12.

[0027] Specifically, in this structure, since the terminal sizes corresponding to different wiring harnesses are different, in order to ensure the transportation of terminals of different sizes, after the terminal is placed in the arc groove 3 opened by the crimping seat 2, the terminal is between the two movable blocks 9, and the elastic potential energy of the movable block 9 by the compression spring 11 can play a stable clamping effect on terminals of different sizes, and the ball 13 is rotated inside the circular groove 12, so that during the transportation of the terminal, the outer wall of the terminal is on the surface of the ball 13 to roll, thereby improving the smoothness of the terminal transportation.

[0029] Specifically, in this structure, when the terminals inside the arc groove 3 are transported, the motor 17 is used to drive the screw rod 15 inside the installation groove to operate, so that the threaded block 16 drives the push plate 14 to move horizontally, and the push plate 14 drives multiple push rods 18 to move, and then the push rods 18 drive the push block 19 to slide inside the arc groove 3, thereby transporting the terminals placed inside the arc groove 3 to ensure that the terminals are connected to the wire harness.

[0030] In a specific embodiment, as shown in the attached Figure 1 , 4 As shown, a plurality of groups of adjustment grooves 20 are provided on the surface of the movable seat 4, and the number of each group of adjustment grooves 20 is set to two. An adjustment block 21 is slidably provided inside the adjustment groove 20, and an adjustment spring 22 is connected to one end of the adjustment block 21 inside the adjustment groove 20.

The output end of the second electric push rod 27 is connected to the slider 26, and the slider 26 is fixedly installed at the bottom of the movable seat 4.

[0033] Specifically, in this structure, after the wire harness is clamped and installed on the surface of the movable seat 4, the second electric push rod 27 drives the slider 26 to slide inside the chute 25, thereby driving the wire harness clamped on the surface of the movable seat 4 to move towards the terminal inside the arc-shaped groove 3, enabling the docking operation when the wire harness is crimped with the terminal.

[0036] Meanwhile, the wire harness to be crimped is placed between two crimping rollers 23. By using two adjusting blocks 21 to slide and adjust relative to each other inside the corresponding adjusting grooves 20, the distance between the two crimping rollers 23 can be adjusted according to the size of the wire harness. Moreover, during the process of the adjusting block 21 sliding inside the adjusting groove 20, the adjusting spring 22 will be compressed, and after the adjusting spring 22 is compressed and then reset, the two crimping rollers 23 will tightly clamp the wire harness, ensuring the stability when one end of the wire harness is movably butted with the terminal;

[0037] The motor 17 drives the lead screw 15 inside the installation groove to rotate, such that the threaded block 16 drives the push plate 14 to move horizontally. The push plate 14 drives a plurality of push rods 18 to move, and further the push rods 18 drive the push block 19 to slide inside the arc-shaped groove 3, thereby transporting the terminal placed inside the arc-shaped groove 3 and ensuring the docking of the terminal with the wire harness;

[0038] Meanwhile, the second electric push rod 27 is used to drive the slider 26 to slide inside the chute 25, thereby driving the wire harness clamped on the surface of the movable seat 4 to move towards the terminal inside the arc-shaped groove 3, so as to perform the docking operation when the wire harness is crimped with the terminal;

[0039] Finally, the first electric push rod 7 drives the movable plate 6 to extend downward, so that the crimping block 8 extends into the arc-shaped groove 3, thereby crimping the wire harness and the terminal.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
