The output shaft of the servo motor 7 is coaxially fixedly connected to one end of the lead screw 5 through a coupling, and the sliding block 9 is slidably connected to the guide rail 3.

[0026] Example 2, refer to Figure 1-2 This embodiment is an optimization based on embodiment 1. Specifically, it is an adjustable wire harness terminal machine, which also includes a wire harness positioning mechanism disposed on the inverted U-shaped frame 2.

[0027] Specifically, the wire harness positioning mechanism includes four guide telescopic rods 16, a clamping cylinder 14 fixedly installed on the inner wall of the top middle of the inverted U-shaped frame 2, and a lower pressure plate 15 fixedly connected to the telescopic end of the clamping cylinder 14.

[0028] Furthermore, the telescopic ends of the four guide telescopic rods 16 are respectively fixed to the outer walls of the four corners of the top of the lower pressure plate 15, and the tops of the four guide telescopic rods 16 are all fixed to the inner wall of the top of the inverted U-shaped frame 2. Through the telescopic guiding effect of the four guide telescopic rods 16, the accuracy and stability of the downward pressing action of the lower pressure plate 15 can be guaranteed.

[0029] Furthermore, the top of the processing base 1 is provided with five equally spaced wire harness placement slots 17, and the bottom of the lower pressure plate 15 is provided with five equally spaced wire harness slots. The five wire harness placement slots 17 are symmetrically distributed above and below the corresponding five wire harness slots.

[0030] In this embodiment, five wire harnesses are placed sequentially in their respective wire harness placement slots 17, and terminal bodies 18 are fitted onto the ends of each wire harness for processing.

Then, under the guidance of the guide rail 3, the adjusting block 8, which is threadedly connected to the lead screw 5, will drive the sliding block 9 to move forward in an orderly manner. When the sliding block 9 moves above each processing station, the two arc-shaped pressure blocks 13 will be moved down to the designated position by the electric push rod 10. The two arc-shaped pressure blocks 13 will be centered and pressed by the pneumatic finger 12 to press and assemble the wire harness and the terminal body 18. After the processing is completed, the electric push rod 10 will control the two arc-shaped pressure blocks 13 to reset and move to the next processing station to repeat the above processing steps. In this way, by flexibly adjusting the working position of the pneumatic stamping component, it can adapt to the processing needs of multiple batches of wire harness terminals, which is conducive to improving production efficiency.
