[0021] Please see Figures 1 to 3This utility model provides a technical solution: a wire harness terminal crimping and positioning device, including a base frame 1, a workbench 2 fixedly connected to the surface of the base frame 1, a first mounting seat 3, a second mounting seat 4, and a third mounting seat 5 fixedly connected to the surface of the workbench 2, a cylinder frame 6 fixedly connected to the surface of the first mounting seat 3, a downwardly oriented lifting cylinder 7 on the cylinder frame 6, and a crimping mold 8 fixedly connected to the bottom of the piston rod of the lifting cylinder 7. A crimping base 9 fixedly connected to the surface of the second mounting seat 4, and a plurality of limiting grooves 10 flush with the loading hole 15 on the surface of the crimping base 9. The surface of the third mounting base 5 is provided with a first support plate 11 and a second support plate 12 fixedly connected. A reciprocating moving mechanism 13 is provided between the first support plate 11 and the second support plate 12. The reciprocating moving mechanism 13 includes a ball screw 1301 rotatably connected between the first support plate 11 and the second support plate 12, a first support rod 1302 and a second support rod 1303 fixedly connected to the first support plate 11 and the second support plate 12 on both sides of the ball screw 1301, and a servo motor 1304 located on the first support plate 11. A movable frame 1305 is provided with a threaded connection on the ball screw 1301. The movable frame 1305 is slidably connected to the first support rod 1302 and the second support rod 1303. A rotary cylinder 14 is installed on the side wall of the movable frame 1305. The piston rod of the rotary cylinder 14 is fixedly connected to the side wall of the feeding plate. The surface of the feeding plate has several equidistant loading holes 15. Above each loading hole 15 is a movable pressure rod 16, which penetrates the feeding plate and has a positioning ring 17 at its bottom. The positioning ring 17 is a downward-facing semi-circular arc shape and is located within the loading hole 15. Several pressure rods 16 are connected by a transverse synchronizing rod 18. A miniature cylinder 19 is provided on the surface of the feeding plate, and the piston rod of the miniature cylinder 19 is fixedly connected to the transverse synchronizing rod 18. A loading platform 20 is located on the surface of the worktable 2 below the feeding plate.

[0023] The specific usage and function of this embodiment are as follows: In use, several wire harness products that need to be crimped can be sequentially placed into the loading holes 15 on the surface of the feeding plate by an automated feeding device. Then, the miniature cylinder 19 located on the surface of the feeding plate drives the horizontal synchronous plate to move downward, thereby realizing that the pressure rod 16 below moves downward synchronously until the bottom positioning ring 17 can press tightly against the wire harness product, ensuring the stability of subsequent movement and crimping. Then, the servo motor 1304 on the reciprocating movement mechanism 13 drives the ball screw 1301 to rotate, thereby enabling the moving frame 1305 to move towards the crimping position. The base 9 moves to one side, allowing the wire harness product on the feeding plate to quickly and stably reach the surface of the crimping base 9 and align with each limit slot 10 in sequence. Then, the lifting cylinder 7 above drives the crimping mold 8 downward to align with the terminal of the wire harness product for crimping. After completion, the servo motor 1304 reverses, driving the receiving seat to move back. After reaching the top of the loading platform 20, the rotary cylinder 14 drives the feeding plate to rotate 90 degrees. Then, the micro cylinder 19 retracts the piston rod, and the crimped wire harness located in the loading hole 15 can fall into the loading platform 20 together, completing the entire crimping process.
