[0019] Combined with appendix Figure 1 and attached Figure 2As shown, a positioning fixture for ultrasonic welding of high-voltage lines includes a support platform 1, a clamping positioning block 2, a positioning block two-axis moving mechanism 3, a terminal positioning seat 4, a positioning seat lifting mechanism 5, a gripper 6, a clamping block 7, and a toothed rack 8. Two mutually symmetrical positioning block two-axis moving mechanisms 3 are installed on the left and right sides of the support platform 1, and the clamping positioning block 2 is installed on the positioning block two-axis moving mechanism 3. The positioning seat lifting mechanism 5 and the gripper 6 are installed on the front and rear sides of the support platform 1, respectively. The terminal positioning seat 4 is installed on the lifting part of the positioning seat lifting mechanism 5. The two fingers of the gripper 6 are fixed with clamping blocks 7. The inner sides of the two clamping blocks 7 are provided with toothed racks 8, and the two toothed racks 8 are staggered.

[0020] As attached Figure 3 As shown, the positioning block two-axis moving mechanism 3 includes a lifting cylinder 31, a horizontal cylinder 32, a slider 33, an inclined groove 34, a pin 35, and a base 36. The piston rod of the lifting cylinder 31 is fixed on the base, and the cylinder body of the lifting cylinder 31 is fixed on the base 36. The slider 33 is slidably connected to the X-axis horizontal straight groove in the base 36. The pressing positioning block 2 is slidably connected to the Y-axis horizontal straight groove on the base 36. The X-axis horizontal straight groove and the Y-axis horizontal straight groove are perpendicular to each other. The upper end face of the slider 33 is provided with an inclined groove 34. The bottom end face of the pressing positioning block 2 is vertically connected to a pin 35, and the bottom end of the pin 35 is placed in the inclined groove 34. The cylinder body of the horizontal cylinder 32 is fixed on one side of the base 36, and the piston rod of the horizontal cylinder 32 is connected to the slider 33.

[0021] The lifting cylinder 31 can drive the pressing and positioning block 2 to move vertically.

[0022] The extension and retraction of the piston rod of the horizontal cylinder 32 can drive the slider 33 to move horizontally and linearly back and forth.

Then, the end of the terminal is placed in the positioning groove of the terminal positioning seat 4, and the tail of the terminal is placed on the support platform 1. Next, the end of the wire harness is placed on the tail of the terminal. At this time, the gripper 6 drives the two gripping blocks 7 to clamp the wire body of the wire harness. The wire body is also engaged by two toothed rows 8, thereby improving the clamping strength. Then, the two positioning block two-axis moving mechanisms 3 drive the two pressing positioning blocks 2 to move above the support platform 1 and then move down until the tail of the terminal and the wire harness are pressed and fixed on the support platform 1. Finally, the positioning seat lifting mechanism 5 drives the terminal positioning seat 4 to move down, so that the terminal positioning seat 4 is disengaged from the terminal, and the ultrasonic welding machine can then weld the connection between the terminal and the wire harness.
