The vehicle charger processing fixture includes: a base 1, a positioning device 2 is provided on the surface of the base 1, and an adjustment device 3 is installed at the edge of the side wall of the base 1; the positioning device 2 includes a rectangular frame 21, and the rectangular frame 21 is fixedly connected to the side wall of the base 1, and a first circular hole 22 is provided on one side of the rectangular frame 21, and the interior of the first circular hole 22 is rotatably connected to a bidirectional screw 23, and the interior of the rectangular frame 21 is rotatably connected to the bidirectional screw 23, and the surface thread shape of the bidirectional screw 23 is arranged in opposite symmetry, and the bidirectional screw 2 3 is symmetrically threadedly connected with the two L-shaped rods 24, the side walls of the two L-shaped rods 24 are provided with rectangular grooves 25, and the surfaces of the two L-shaped rods 24 are provided with multiple plug holes 26; the inside of the rectangular groove 25 is slidably connected to the round hole block 28, one side of the round hole block 28 is fixedly connected to the clamping block 29, the pin 210 passes through the plug hole 26 and is slidably connected to the inside of the round hole block 28, and the surface size and shape of the pin 210 are adapted to the size and shape of the inner wall of the plug hole 26; when the on-board charger needs to be fixed, first place the on-board charger on the base 1 On the top, move the clamp block 29 so that the clamp block 29 drives the circular hole block 28 to move along the inside of the rectangular groove 25. When the circular hole block 28 moves to the schematic position and is aligned with one of the insertion holes 26, the latch 210 passes through the insertion hole 26 and is inserted into the circular hole block 28 to limit the circular hole block 28, thereby completing the position adjustment of the clamp block 29. When the position adjustment of all the clamp blocks 29 is completed, the bidirectional screw 23 is rotated at this time, and the surface thread shape of the bidirectional screw 23 is arranged in opposite symmetry by utilizing the principle of screw transmission. The rotation of the bidirectional screw 23 drives the two L-shaped rods 24 to move toward each other, and the L-shaped rod 24 drives the clamping block 29 to move toward the direction of the on-board charger, so that the clamping block 29 squeezes and fixes the on-board charger, completing the clamping and positioning of the charger, so that workers can adapt to different types of chargers by adjusting the positions of the clamping block 29 and the L-shaped rod 24 to clamp and fix them, reducing the need to replace the adapter fixture when positioning different types of chargers, resulting in material waste and reduced detection efficiency, and improving the convenience and flexibility of positioning different types of chargers.

The latch 210 is rotated, and the latch 210 drives the limiting column 214 and the protrusion 215 to rotate inside the limiting hole 217. The protrusion 215 is aligned with the limiting plate 216, so that the limiting column 214 is fixed inside the limiting hole 217, preventing the latch 210 from being separated from the circular hole block 28, and increasing the stability and firmness of the clamping block 29 on the side wall of the L-shaped rod 24. When the position adjustment of all the clamping blocks 29 is completed, the bidirectional screw 23 is rotated at this time. The principle of screw transmission is utilized. At the same time, the surface thread shapes of the bidirectional screw 23 are arranged in opposite symmetry. The rotation of the bidirectional screw 23 drives the two L-shaped rods 24 to move in opposite directions. The L-shaped rod 24 drives the clamping block 29 and the rubber pad 213 to move toward the direction of the on-board charger, so that the rubber pad 213 squeezes and fixes the on-board charger, completing the clamping and positioning of the charger, so that workers can adapt to different models of chargers by adjusting the positions of the clamping block 29 and the L-shaped rod 24 to clamp and fix them, reducing the need to replace the adapter fixture when positioning different models of chargers, resulting in material waste and detection The efficiency is reduced, and the convenience and flexibility of positioning different types of chargers are improved; during detection, if the height of the base 1 is not suitable, the bolt 36 is rotated, the bolt 36 is disengaged from the support rod 34, and the support rod 34 is slid inside the second circular hole 31 to change the height of the base 1; when the height of the base 1 is suitable, and the inner wall of the third circular hole 32 coincides with the inner wall of one of the threaded grooves 35, the bolt 36 is rotated to rotate into the threaded groove 35 to fix the support rod 34, and the height adjustment of the base 1 is completed; the inconvenience of personnel or equipment detection caused by height mismatch after the on-board charger is positioned on the base 1 is reduced.
