[0020] When processing the electric vehicle instrument circuit board, first adjust the circuit board platform 1 to a suitable height, place the electric vehicle instrument circuit board on the circuit board platform 1, drive the alignment clamping plate 2 to move toward the middle, so that the front and rear sides of the electric vehicle instrument circuit board are in contact with the limiting pressure plate 22, and the spring 23 at the side end of the limiting pressure plate 22 elastically pushes the front and rear sides of the electric vehicle instrument circuit board to align and press between the limiting pressure plates 22, and then connect the negative pressure pipeline to make the negative pressure hole 24 adsorb the lower surface of the electric vehicle instrument circuit board, rotate the driving column head 13, and move the side clamping plate 3 toward the middle. The movement of the side clamping plate 3 simultaneously pushes the longitudinal adjustment frame 11 to move left and right, and clamps the electric vehicle instrument circuit board clamped at the upper end of the longitudinal adjustment frame 11 in the center position to ensure the stability of the clamping support, and then the clamped electric vehicle instrument circuit board can be processed. When the processing position is blocked during processing, adjust the position of the two sets of alignment clamping plates 2 to make the electric vehicle instrument circuit board shift to one side, so that the processing position is in an unobstructed state and the processing of the electric vehicle instrument circuit board can continue.

[0021] In this embodiment, the middle part of the lower end surface of the circuit board platform 1 is connected to the support base 4 through an electric push rod 41; and the electric push rod 41 is embedded and fixed inside the support base 4.

[0024] As a preferred embodiment, the two groups of threaded rods 12 rotate by driving the column head 13, so that the two groups of drive blocks 32 on the surface move closer or farther away synchronously, which facilitates the side clamping plate 3 to clamp the left and right sides of the electric vehicle instrument circuit board, ensures the stable clamping of the electric vehicle instrument circuit board, and at the same time clamps and moves the electric vehicle instrument circuit board to the center position.

[0025] In this embodiment, the lower end surface of the alignment clamping plate 2 is slidably connected to the electric slide 15 via a slider 25 , and the side end of the alignment clamping plate 2 is connected to a negative pressure pipeline via a negative pressure pipe joint 21 .

[0026] As a preferred embodiment, the electric slide 15 moves forward and backward by driving the slider 25 to move, thereby clamping the front and rear sides of the electric vehicle instrument panel circuit board. The negative pressure pipeline is connected to the adsorption hole 24 through the internal chamber of the alignment clamp 2, so that the alignment clamp 2 is adsorbed by negative pressure.

It forms a cross clamping structure for the electric vehicle instrument circuit board, reduces the clamping area, and conveniently reserves more processing space. It is convenient to adjust the processing position of the clamped electric vehicle instrument circuit board, avoids the clamping device from limiting and hindering the normal processing operation, and is suitable for the clamping device for processing electric vehicle instrument circuit boards.
