[0017] Now, the present utility model will be further described in detail in conjunction with the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0018] Figure 1 is a structural schematic diagram of the present utility model; Figure 2 is a structural schematic diagram of the horizontal cylinder, slide plate, and slide plate stroke limiting mechanism of the present utility model.

[0019] Combined with the attached Figure 1 and the attached Figure 2 As shown, a welding fixture with a pressing block stroke adjustment includes a base 1, a lifting mechanism 2, a base 3, a horizontal cylinder 4, a slide plate 5, a pressing block 6, a slide plate stroke limiting mechanism 7, a wire harness positioning mechanism 8, a wire harness clamping mechanism 9, and a terminal support 10. The wire harness positioning mechanism 8, the wire harness clamping mechanism 9, the terminal support 10, and two lifting mechanisms 2 are installed on the base 1. The wire harness clamping mechanism 9 and the terminal support 10 are located between the two lifting mechanisms 2. The base 3 is fixed on the lifting mechanism 2. The slide plate 5 and the pressing block 6 are slidably connected to the base 3. The slide plate 5 is fixed on the piston rod of the horizontal cylinder 4. An inclined groove 11 is provided on the slide plate 5. A pin 12 is provided at the bottom of the pressing block 6. The pin 12 is placed in the inclined groove 11. A spring is connected between the pressing block 6 and the base 3. The slide plate stroke limiting mechanism 7 is installed on the base 3. The slide plate stroke limiting mechanism 7 is located in front of the slide plate 5.

[0020] The horizontal cylinder 4 drives the slide plate 5 to move horizontally left and right. The moving slide plate 5 will force the pin 12 to move along the inclined groove 11, thereby driving the pressing block 6 to move horizontally back and forth. Since the diameter of the pin 12 is smaller than the width of the inclined groove 11, the gap between the pin 12 and the inclined groove 11 will cause the stroke of the moving slide plate 5 to not be completely converted into the stroke of the pressing block 6. The spring on the pressing block 6 will pull the pressing block 6 and the pin 12 against the inclined groove 11, thereby eliminating the gap. Until the slide plate 5 moves forward and abuts against the slide plate stroke limiting mechanism 7.

[0021] The slide plate stroke limiting mechanism 7 is a bolt. The slide plate stroke limiting mechanism 7 is threadedly connected to the threaded hole in the front end plate of the base 3. Rotating the slide plate stroke limiting mechanism 7, the slide plate stroke limiting mechanism 7 will move forward or backward along the threaded hole, so that the maximum forward stroke of the slide plate 5 can be adjusted.

[0022] The wire harness positioning mechanism 8 includes a positioning block 81, a positioning block lifting cylinder 82, and a positioning block horizontal moving cylinder 83. The cylinder body of the positioning block lifting cylinder 82 is fixed on the base 1. The piston rod of the positioning block lifting cylinder 82 is fixed with the positioning block horizontal moving cylinder 83. The piston rod of the positioning block horizontal moving cylinder 83 is fixed with the positioning block 81.

[0023] The positioning block lifting cylinder 82 can drive the positioning block 81 to move up and down. The positioning block horizontal moving cylinder 83 can drive the positioning block 81 to move horizontally. When the positioning block 81 moves in front of the terminal support 10 and the wire harness terminal abuts against the positioning block 81, the wire harness can be positioned at the welding position.

[0024] The wire harness clamping mechanism 9 includes a finger cylinder 91, a clamping plate 92, and a wire harness support block 93. The cylinder block of the finger cylinder 91 is fixed on the sliding seat 13. Clamping plates 92 are respectively fixed on the two fingers of the finger cylinder 91. C-shaped grooves are provided on the clamping plates 92. A wire harness support block 93 is fixed to the rear end of the cylinder block of the finger cylinder 91.

[0025] The wire harness is placed on the wire harness support block 93. After the wire harness is positioned, the finger cylinder 91 drives the two clamping plates 92 to clamp and fix the wire harness.

[0026] The terminal support 10 is fixedly connected to the sliding seat 13.

[0027] The lifting mechanism 2 includes a single-rod cylinder, an outer box body, and an inner box body. The inner box body is fixed on the base 1. The inner box body is slidably connected inside the outer box body. The cylinder block of the single-rod cylinder is fixed inside the outer box body. The piston rod of the single-rod cylinder is fixed on the base 1. The base 3 is fixed on the top of the outer box body.

[0028] Specifically, the base 1 includes an upper layer plate 21, a lower layer plate 22, arc-shaped strip holes 23, adjusting bolts 24, and screws. The upper layer plate 21 is placed on the lower layer plate 22. Two symmetric arc-shaped strip holes 23 are provided on the left and right sides of the upper layer plate 21. Two screws are threadedly connected to the lower layer plate 22. The two screws respectively pass through the two arc-shaped strip holes 23. An adjusting bolt 24 for propping against the upper layer plate 21 is rotatably connected to one side of the lower layer plate 22.

[0029] The upper layer plate 21 can rotate on the lower layer plate 22. When rotating, the screws will move along the arc-shaped strip holes 23. After the upper layer plate 21 rotates and abuts against the adjusting bolt 24, the screws can be tightened, thereby fixedly connecting the upper layer plate 21 to the lower layer plate 22 and realizing the adjustment of the horizontal orientation of the welding positioning seat.

[0030] The working mode of this application is as follows: Place the terminal on the terminal support 10. The two horizontal cylinders 4 drive the two pressing blocks 6 to move towards the left and right sides of the terminal through the sliding plate 5. The lifting mechanism 2 drives the pressing blocks 6 to move downward. The two pressing blocks 6 can press the terminal tightly on the terminal support 10. The wire harness positioning mechanism 8 positions the terminal wire harness to the welding position. The wire harness clamping mechanism 9 clamps and fixes the wire harness. Finally, the wire harness and the terminal can be welded.
