High-precision positioning mechanism for new energy automobile circuit board machining

The invention discloses a new energy automobile circuit board machining high-precision positioning mechanism which comprises supports, fixing blocks, guide rods, mounting blocks, air cylinders, stable clamping devices and lifting devices.The stable clamping devices are arranged at the upper ends of the interiors of the two supports and can be pushed by the air cylinders, and under pushing, the stable clamping devices can stably clamp the circuit board. The inner supporting piece can stably clamp the left side and the right side of the circuit board, the side edge stabilizing mechanism is arranged at the top of the supporting piece and can be driven by a motor to stabilize the front side and the rear side of the circuit board, and the bottom pressing and fixing mechanisms are arranged at the front end and the rear end of the bottom of the supporting piece and can support, lift and stabilize the bottom of the circuit board. And the lifting device is arranged in the middle of the interior of the support, the hei
