In addition, its fixed tooling structure is mainly pneumatic clamps, and the contact reinforcement of the terminal component surface requires high precision, which poses a hidden danger of damaging the terminal surface. Therefore, in order to solve the above problems, a crimping mechanism that improves the stability of the wiring harness terminal is proposed. Utility Model Content

The guide frames 3 are located on both sides of the top of the base plate 1, and a U-shaped push plate 2 is provided at the bottom of each guide frame 3. The middle part of the back side of the U-shaped push plate 2 is connected to the push rod end of the crimping cylinder 7, and a fixed plate 4 is installed on one side of the side hole 201 located at the top of the U-shaped push plate 2. The die base 8 arranged in the U-shaped push plate 2 is fixedly connected to one end of the strip block 11 located on the guide rail 12, and an electromagnet 15 is installed at the bottom of the placement groove 801 located on the die base 8. The electromagnet 15 and the steel plate 401 located on the back side of the rubber plate 404 form an electromagnetic clamping fixture, and one end of the guide rail 12 is connected to the traction slider 10 located on the linear motor 9.

[0022] Specific as Figure 4 As shown, guide rods 402 are installed at the four corners of the back side of the steel plate 401, and the guide rods 402 slide in the corresponding hole structure on the fixed plate 4. A spring 403 is mounted on the outer end of the guide rod 402. The spring 403 is used to move and reset the rubber plate 404 connected to the steel plate 401.

[0023] Specific as Figure 1As shown, one side of the guide rail 12 is alternately connected with a long slide bar 13, and the long slide bar 13 is slidably connected to the hole structure located on the strip block 11, and one side of the long slide bar 13 is fitted with a spring three 14. The long slide bar 13 cooperates with the guide rail 12 and under the action of the spring three 14, the stability of the connected mold base 8 and the U-shaped push plate 2 when they are moved to the crimping position is ensured.

[0024] There are two linear motors 9, and the two linear motors 9 are installed on one side of the base plate 1; the two ends of the U-shaped guide rod 5 are fixedly connected to the two sides of the back side of the U-shaped push plate 2, and the rod bodies on both sides of the U-shaped guide rod 5 are both equipped with springs 6; the top and one side of the guide frame 3 are both frame-shaped, and the two hole structures on the other side of the guide frame 3 are in sliding contact with the corresponding parts of the U-shaped guide rod 5.

Then, the two crimping oil cylinders 7 are synchronously operated to extend to move the two fixed crimped terminal parts in opposite directions and implement the crimping operation.
