Detailed implementation mode

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-5, the present utility model provides a technical solution: a high-precision terminal crimping device for wire harnesses, including the main body 1 of the wire harness terminal crimping device. There is a lower support base 2 on the main body 1 of the wire harness terminal crimping device, and a lower crimping die 7 is installed at the upper end of the lower support base 2. Above the lower support base 2, there is an upper mounting base 13, and a crimping driving mechanism 12 is installed on the upper mounting base 13. The crimping driving mechanism 12 is a hydraulic cylinder used for crimping drive on existing wire harness terminal crimping devices, and the movable end of the crimping driving mechanism 12 is connected to an upper crimping die 14. There is a protective cover 4 at the upper end of the lower support base 2, and a wire inlet hole 401 is opened at the front end of the protective cover 4, through which the wire harness can be inserted into the main body 1 of the wire harness terminal crimping device, and the crimping protection is carried out through the protective cover 4. Side support plates 3 are symmetrically screwed and fixed at the upper end of the lower support base 2, and the protective cover 4 is in snap-fit connection with the lower support base 2 and the side support plates 3. First positioning columns 9 are also symmetrically inserted and fastened at the upper end of the lower support base 2, and an arc-shaped limiting rod 5 is screwed and fixed at the upper end of the first positioning column 9. This structure can form a support structure for the main body 1 of the wire harness terminal crimping device through the lower support base 2, the side support plates 3, and the upper mounting base 13. The protective cover 4 is used for the protective treatment of terminal crimping to ensure production safety. The first positioning column 9 can play a role in fixing the arc-shaped limiting rod 5. Second positioning columns 10 are symmetrically arranged on both sides of the wire inlet hole 401 at the upper end of the lower support base 2. The second positioning columns 10 are fixed on the lower support base 2 by screwing, and a connecting rod 6 is movably sleeved at the upper end of the second positioning column 10. An arc-shaped limiting hole 502 is formed in the arc-shaped limiting rod 5, and the limiting hole 502 is centered on the second positioning column 10. A spring 501 is also clamped and fastened in the limiting hole 502. This structure enables the structure limited by the limiting hole 502 to move around the second positioning column 10. The other end of the connecting rod 6 is rotatably installed with a wire harness feeding guide roller 8, and a rotation driving mechanism 801 for driving the rotation of the wire harness feeding guide roller 8 is installed at the upper end of the connecting rod 6. The rotation driving mechanism 801 is an existing motor structure for driving the wire harness feeding guide roller 8 to rotate. The two wire harness feeding guide rollers 8 rotate in different directions to form a clamping conveying force, enabling the wire harness feeding guide roller 8 to perform clamping and moving processing on the wire harness, accurately controlling the wire inlet distance of the wire harness, thereby ensuring the insertion distance between the wire harness and the terminal, and further ensuring the accuracy of the terminal crimping position and the quality of wire harness terminal crimping. The connecting rod 6 is horizontally arranged, and a limiting stud 601 is fixed at the upper end of the connecting rod 6 through a threaded hole. This structure functions to relatively connect the wire harness feeding guide roller 8 and the second positioning column 10 through the connecting rod 6, enabling the wire harness feeding guide roller 8 to rotate relative to the second positioning column 10 through the connecting rod 6, and the connecting rod 6 limits the rotation of the wire harness feeding guide roller 8 relative to the second positioning column 10 through the arc-shaped limiting rod 5. The limiting stud 601 movably penetrates through the limiting hole 502, and the other end of the spring 501 is hooked on the limiting stud 601. This structure can enable the connecting rod 6 to move relative to the arc-shaped limiting rod 5 through the limitation of the limiting stud 601 and the limiting hole 502,The spring 501 can be compressed by the limit stud 601, and then the clamping and fastening of the wire harness by the wire harness feeding guide roller 8 can be realized through the rebounding force of the spring 501. A fixed frame 11 is arranged below the connecting rods 6. The fixed frame 11 adopts a U-shaped structure, and a supporting roller 1101 with a cam structure is rotatably installed at the upper end of the fixed frame 11, which can support the bottom of the wire harness to prevent the wire harness from being rubbed during clamping and conveying. Terminal positioning grooves 701 and crimping grooves 1401 are respectively formed at the upper end of the lower crimping die 7 and the lower end of the upper crimping die 14, and the positions of the terminal positioning grooves 701 and the crimping grooves 1401 correspond to each other. This structure can position the terminals through the terminal positioning grooves 701, and then the lower crimping die 7 and the upper crimping die 14 cooperate to crimp and fix the wire harness and the terminals.,

[0020] Working principle: When using this high-precision terminal crimping device for wire harnesses, first, the terminals for wire harness crimping are placed in the lower crimping die 7 through the terminal positioning grooves 701. The wire harness is inserted into the main body 1 of the wire harness terminal crimping device through the inlet hole 401. After the end of the wire harness is clamped between the wire harness feeding guide rollers 8, the wire harness feeding guide rollers 8 are driven by the rotation drive mechanism 801 under the positioning of the connecting rods 6 to clamp and convey the wire harness, accurately controlling the distance between the end of the wire harness and the inserted terminal, realizing the precise positioning of the end of the wire harness, ensuring the crimping quality of the terminals. When the wire harness is clamped between the wire harness feeding guide rollers 8, the connecting rods 6 rotate under the positioning of the second positioning posts 10, so that the limit studs 601 move under the limitation of the limit holes 502, realizing the rotational limit of the arc-shaped limiting rod 5 on the connecting rods 6. At the same time, the limit studs 601 compress the spring 501, realizing the stable positioning of the wire harness feeding guide rollers 8 on the wire harness. The first positioning posts 9 play a role in stably installing the arc-shaped limiting rod 5. After the end of the wire harness is inserted into the terminal, the supporting roller 1101 supports the wire harness. The fixed frame 11 fixes the supporting roller 1101 between the wire harness feeding guide rollers 8. The crimping drive mechanism 12 drives the upper crimping die 14 to move downward under the positioning of the upper mounting seat 13, and the terminals are crimped through the cooperation of the crimping groove 1401 and the lower crimping die 7. The lower support seat 2 reliably supports the upper mounting seat 13 through the side support plates 3, and the crimping is protected by the protective cover 4, thus completing a series of operations.

[0021] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
