[0032] See also Figure 1-3 A fastening device for an instrument panel shell of an electric vehicle comprises a processing table 1, and a positioning assembly for positioning the instrument panel is arranged on the upper side of the processing table 1. The positioning assembly comprises a base 2 detachably connected to the upper side of the processing table 1, a workpiece pallet frame 4 is fixedly connected to the middle part of the upper side of the base 2, a pallet 15 is detachably connected to the interior of the upper side of the workpiece pallet frame 4, two support plates 10 are fixedly connected to the left and right ends of the upper side of the base 2, a rotating rod 3 is rotatably connected to the interior of the upper sides of the two support plates 10, a spring 9 is fixedly connected to the lower side of the rotating rod 3, a protrusion 11 is fixedly connected to the upper side of one end of the rotating rod 3 close to the support plate 10, the protrusion 11 penetrates the inner bottom wall of the workpiece pallet frame 4 and is located below the pallet 15, and a clamping assembly for clamping the instrument panel is arranged on the upper end of the rear side of the base 2.

[0033] Among them, the processing table 1 and the base 2 are fixedly connected by multiple bolts, and four top baffles 13 are fixedly connected to the inner wall of the upper side of the workpiece pallet frame 4, and the four top baffles 13 are arranged in a circle. Four bottom blocks 12 are fixedly connected to the inside of the lower side of the workpiece pallet frame 4, and the four bottom blocks 12 are respectively fixedly connected to the lower side of the top baffle 13, and four limit plates 14 that are in contact with the bottom of the top baffle 13 are fixedly connected to the upper side of the pallet 15, wherein the limit plate 14 passes between two adjacent baffles 13, there are two springs 9, and the two springs 9 are arranged horizontally, and the inner sides of the two support plates 10 are sleeved with movable shafts, and the inner walls of the movable shafts are sleeved and fixed to the outer side of the rotating rod 3, the protrusions 11 and the pallet 15 are arranged up and down, and the surfaces of the top baffle 13 and the bottom block 12 are both arc-shaped block structures.

[0034] It should be noted that the end of the rotating rod 3 close to the protrusion 11 passes through the workpiece pallet frame 4 and extends to the inside. When the rotating rod 3 rotates using the movable axis, it can drive the protrusion 11 to move upward and push the lower side of the pallet 15 to move upward in a straight line. The pressing and rebounding force of the spring 9 can restore the rotating rod 3 to its original position, making it convenient and faster to remove the pallet 15 and replace it.

[0037] The working principle of the above embodiment is:

[0038] Take out the corresponding pallet 15 according to the size of the instrument panel to be assembled, put it into the workpiece pallet frame 4 from between the top baffles 13 on the upper side, then rotate the limit plate 14 to abut against the lower side of the top baffle 13, and the lower side of the pallet 15 is clamped into the workpiece pallet frame 4 by the bottom stopper 12. The instrument panel is placed on the upper side of the pallet 15, and then the shell is placed on the upper side of the instrument panel. Then, the telescopic end of the cylinder 7 is started to extend the clamping plate 8 to move toward the shell. With the continuous pressure, the instrument panel and the shell are squeezed and fixed together. When the clamping plate 8 is separated, The clamped instrument panel and shell can be taken out, which effectively improves the production efficiency. When it is necessary to clamp instrument panels of other sizes, the limit plate 14 is rotated to separate from the lower side of the top baffle 13, so that the limit plate 14 is located in the empty space between the two adjacent top baffles 13, and the rotating rod 3 is pressed to rotate the movable shaft on the upper side of the support plate 10 to make the rotating rod 3 with a protrusion 11 at the other end tilt upward, and the upper side of the protrusion 11 just contacts the lower side of the tray 15, and the tray 15 is directly ejected from the workpiece tray rack 4, so that the tray 15 can be quickly removed and replaced.
