[0029] The structure of the probe positioning crimping device disclosed in the present invention is as follows: Figure 1 As shown, specifically including:

[0030] A fixed base plate 1, which serves to fasten and support the entire device;

[0031] A crimping mechanism 2, used for crimping a semi-finished probe, such as Figure 2 , 3 , and 4, comprising a lower pressing plate 2-1 fixed on a fixed bottom plate 1, a mold plate 2-2 fixed on the lower pressing plate 2-1, a cam 2-3 inlaid outside the mold plate 2-2 and rotatable around an axis, a core mold 2-4 is provided at the center of the mold plate 2-2, and three punches 2-5 are evenly arranged along the circumference of the mold plate 2-2, and the punches 2-5 pass through the mold plate 2-2 and are inserted into the core mold 2-4;

[0032] A push positioning mechanism 3 is used to push the cam 2-3 to rotate, and further drive the punch 2-5 to crimp the semi-finished probe. Figure 5 As shown, it includes a cylinder 3-2 fixed on a fixed base plate 1, a cylinder joint 3-3 is connected to the cylinder 3-2, the cylinder joint 3-3 is connected to the cam 2-3, and a micrometer head 3-5 is fixed on the end of the fixed base plate 1 away from the cylinder 3-2, and the micrometer head 3-5 is used to locate the position of the cylinder joint 3-3.

[0033] The probe positioning and crimping device of the present invention is provided with a crimping mechanism 2 and a pushing and positioning mechanism 3. During crimping, the semi-finished probe is placed in the core mold 2-4 of the crimping mechanism 2 and pressed tightly. Then, the cylinder 3-2 in the pushing and positioning mechanism 3 drives the cylinder joint 3-3, which further drives the cam 2-3 to rotate, and presses the punch needle 2-5 toward the semi-finished probe. When the cylinder joint 3-3 reaches the positioning position of the micro-side head 3-5, the crimping of the semi-finished probe is completed. The entire crimping process does not require manual operation, thereby improving production capacity while ensuring product quality.

[0034] It should be noted that the cylinder 3 - 2 is fixed on the cylinder fixing plate 3 - 1 , and the cylinder fixing plate 3 - 1 is fixed on the fixed base plate 1 ; the micrometer head 3 - 5 is fixed on the micrometer head fixing plate 3 - 4 , and the micrometer head fixing plate 3 - 4 is fixed on the fixed base plate 1 .

[0035] like Figure 6 As shown, a center hole 2-2-1 is provided at the center of the mold plate 2-2, and three grooves 2-2-2 are evenly arranged along the circumference of the mold plate 2-2. A hole 2-2-3 is provided at the bottom end of each groove 2-2-2. The hole 2-2-3 is connected to the center hole 2-2-1, and the punching needle 2-5 passes through the hole 2-2-3. The core mold 2-4 is arranged in the center hole 2-2-1, as shown in FIG. Figure 7 As shown, the center of the core mold 2-4 is provided with a product placement hole 2-4-1, and the side wall of the core mold 2-4 is evenly provided with through holes 2-4-2 along the axial direction. The product placement hole 2-4-1 is perpendicular to and connected to the through hole 2-4-2, and the through hole 2-4-2 is connected to the hole 2-2-3. The punch 2-5 passes through the hole 2-2-3 and extends into the through hole 2-4-2. During crimping, the semi-finished probe is located in the product placement hole 2-4-1, and the cam 2-3 rotates to squeeze the punch 2-5 so that it passes through the hole 2-2-3 and the through hole 2-4-2 in turn, and the semi-finished probe is crimped.

[0036] like Figure 2 and Figure 3 As shown, the mold plate 2-2 is also fixed with an upper pressing plate 2-6, which is in a circular ring shape and serves as a limit for the cam 2-3; the mold plate 2-2 is fixed with a product guide block 2-7 by a pin, which serves as a guide for placing the semi-finished product probe, and the product guide block 2-7 is located above the core mold 2-4, and a guide hole 2-7-1 is provided in the center of the product guide block 2-7, which serves as a guide, and the guide hole 2-7-1 is connected to the product placement hole 2-4-1. When crimping, the semi-finished product probe is placed in the guide hole 2-7-1 in the product guide block 2-7, and then enters the product placement hole 2-4-1 of the core mold 2-4.

[0037] It should be noted that the above-mentioned fixing or fastening is all fixed or fastened by fastening screws or set screws, which facilitates disassembly, maintenance or replacement of parts and reduces maintenance costs.

[0038] The probe positioning and crimping device disclosed in the present invention, during crimping, firstly places the semi-finished product probe in the guide hole 2-7-1 of the product guide block 2-7, and then enters the product placement hole 2-4-1 of the core mold 2-4, and is pressed (either manually or by using an existing pressing device), and then starts the movement of the cylinder 3-2, the cylinder 3-2 drives the cylinder joint 3-3, and further drives the cam 2-3 to rotate, pressing the punch needle 2-5 toward the semi-finished product probe, and when the cylinder joint 3-3 reaches the positioning position of the micro-side head 3-5, the crimping of the semi-finished product probe is completed, and then the cylinder 3-2 returns to the original position to complete the crimping process.

[0039] The probe positioning and crimping device disclosed in the present invention is specially used for crimping precision probes, and largely replaces manual work in the processing link, ensuring that the crimping position, adjacent crimping angles, crimping depth, and crimping appearance of each finished precision probe remain highly consistent, which not only improves the crimping quality, but also greatly improves work efficiency, and has very good market promotion prospects.
