The positioning block moves horizontally along the X-axis using an X-axis moving terminal / wire harness positioning mechanism, and horizontally along the Y-axis using a Y-axis moving terminal / wire harness positioning mechanism. This allows for the selection of which positioning mechanism to use for positioning the terminals and wire harness based on the direction of movement of the welding torch on site.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] Schematic diagram; Figure 3 This is a schematic diagram of the horizontal moving mechanism of the pressing block of this utility model.

[0022] As attached Figure 1 As shown, a multi-directional positioning terminal positioning fixture includes a carrier 1, a terminal clamping block 2, a clamping block lifting mechanism 3, a clamping block horizontal moving mechanism 4, a clamping block stroke limiting mechanism 5, a wire clamping mechanism 6, an X-axis moving terminal harness positioning mechanism 7, a Y-axis moving terminal harness positioning mechanism 8, and a base plate 9. The base plate 9 is equipped with the carrier 1, the clamping block lifting mechanism 3, the wire clamping mechanism 6, the X-axis moving terminal harness positioning mechanism 7, and the Y-axis moving terminal harness positioning mechanism 8. The two clamping block lifting mechanisms 3 are located on the left and right sides of the carrier 1, respectively. The Y-axis moving terminal harness positioning mechanism 8 is located behind the carrier 1, and the wire clamping mechanism 6 is located in front of the carrier 1. The clamping block lifting mechanism 3 is connected to the clamping block horizontal moving mechanism 4, and the clamping block 2 is connected to the clamping block horizontal moving mechanism 4. The X-axis moving terminal harness positioning mechanism 7 is installed on one of the clamping block lifting mechanisms 3.

[0023] The X-axis moving terminal harness positioning mechanism 7 includes a single-rod cylinder 71, a rotating plate 72, and a baffle 73. The cylinder body of the single-rod cylinder 71 is hinged to the horizontal moving mechanism 4 of the pressure block, and the piston rod of the single-rod cylinder 71 is hinged to the left side of the rotating plate 72. The baffle 73 is fixed to the right side of the rotating plate 72, and the lower side of the rotating plate 72 is hinged to the horizontal moving mechanism 4 of the pressure block.

[0024] The piston rod of the single-rod cylinder 71 extends and retracts, which can pull the rotating plate 72 to rotate back and forth in the left and right directions of the X-axis. This allows the baffle 73 to be swung to the front of the carrier 1 or moved away from the front of the carrier 1.

[0025] The Y-axis movable terminal harness positioning mechanism 8 includes a horizontal slide cylinder 81 and a baffle 82. The cylinder body of the horizontal slide cylinder 81 is fixed on the base plate 9, and the slide of the horizontal slide cylinder 81 is fixed at the rear end of the baffle 82. The piston rod of the horizontal slide cylinder 81 is perpendicular to the piston rod of the single rod cylinder 71.

[0026] The horizontal slide cylinder 81 can drive the baffle 82 to move horizontally in the Y-axis direction.

[0027] The pressing block lifting mechanism 3 includes a lifting cylinder 31 and a lifting housing 32. The cylinder body of the lifting cylinder 31 is fixed on the base plate 9, and the lifting housing 32 is fixed on the piston rod of the lifting cylinder 31. The cylinder body of the single-rod cylinder 71 and the rotating plate 72 are both hinged to the lifting housing 32.

[0028] The lifting cylinder 31 can drive the lifting housing 32 and the terminal pressure block 2 to move up and down.

[0029] As attached Figure 3 As shown, the horizontal moving mechanism 4 of the pressure block includes a horizontal cylinder 41, a horizontal slide plate 42, an inclined groove 43, and a pin 44. The cylinder body of the horizontal cylinder 41 is fixed on the lifting housing 32, and the piston rod of the horizontal cylinder 41 is fixed on the horizontal slide plate 42. The horizontal slide plate 42 is slidably connected to the horizontal straight groove inside the lifting housing 32. The horizontal slide plate 42 is provided with an inclined groove 43. One end of the pin 44 is connected to the bottom of the terminal pressure block 2, and the other end of the pin 44 is placed in the inclined groove 43. The pin 44 and the end face of the horizontal slide plate 42 are perpendicular to each other. The terminal pressure block 2 is slidably connected to the horizontal straight groove at the outer end of the lifting housing 32.

[0030] The horizontal cylinder 41 drives the horizontal slide plate 42 to move horizontally back and forth, thereby causing the pin 44 to move along the inclined groove 43, which in turn drives the terminal pressure block 2 connected to the pin 44 to move horizontally in a straight line.

[0031] As attached Figure 2 As shown, the pressure block stroke limiting mechanism 5 includes an inclined block 51, a pin 52, and an adjusting screw. The inclined block 51 has an inclined surface for blocking the pin 52. The pin 52 is vertically connected to the tail end of the terminal pressure block 2. The terminal pressure block 2 is slidably connected to the inside of the lifting housing 32. The adjusting screw is threadedly connected to the threaded hole of the lifting housing 32, and the end of the adjusting screw is movably connected to the inclined block 51.

[0032] Rotating the adjusting screw allows it to move horizontally along the threaded hole, thereby causing the inclined block 51 to move horizontally back and forth. When the terminal pressure block 2 moves forward, the pin 52 at the tail end of the terminal pressure block 2 will stop moving when it hits the inclined surface of the inclined block 51, thus achieving the purpose of limiting the forward stroke of the terminal pressure block 2.

[0033] The wire clamping mechanism 6 includes a jaw and clamping blocks. The cylinder of the jaw is fixed to the base plate 9, and clamping blocks are fixed to both fingers of the jaw. The jaw controls the opening and closing of the two clamping blocks to clamp and fix the wire harness.

[0034] The working method of this application is as follows: First, the terminal is placed on the carrier 1, and the baffle 73 of the X-axis movable terminal harness positioning mechanism 7 or the baffle 82 of the Y-axis movable terminal harness positioning mechanism 8 is placed in front of the carrier 1. The terminal rests on the baffle 73 or the baffle 82. Then, the terminal pressing blocks 2 on the left and right sides move horizontally towards the terminal, and after moving above the terminal, they move downward, thereby pressing the left and right sides of the terminal firmly onto the carrier 1. Next, the wire harness is passed through the two clamping blocks of the wire clamping mechanism 6 and moved onto the terminal, with the wire harness end resting on the baffle 73 or the baffle 82. The two clamping blocks of the wire clamping mechanism 6 clamp the wire harness, thus completing the positioning of the terminal and the wire harness. Finally, the terminal and the wire harness end can be soldered.

[0035] If the welding torch moves in the Y-axis forward-backward direction, swing the baffle 73 outward and away from the carrier 1, allowing the baffle 82 to move forward to the front end of the carrier 1 for positioning the terminals and wire harness. If the welding torch moves in the X-axis horizontal direction, place the baffle 73 at the front end of the carrier 1 for positioning the terminals and wire harness.

[0036] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
