[0005] The utility model is an inspection tool for the bottom guard plate of an automotive power battery, including a pedestal. A profiling support frame, a plurality of crossbeam fixing seats and a plurality of edge fixing seats are fixed on the upper surface of the pedestal. The crossbeam fixing seats are symmetrically arranged on both sides of the profiling support frame, and the edge fixing seats are arranged on the circumferential side surface of the profiling support frame. A first vertical elbow clamp presser is fixed on the upper surface of the crossbeam fixing seat, and a second vertical elbow clamp presser is fixed on the upper surface of the edge fixing seat. A positioning post is arranged on the upper surface of the profiling support frame, and a plurality of dial indicators and profiling support blocks are arranged on the upper surface of the pedestal located inside the profiling support frame. The display device of the dial indicator is arranged outside the profiling support frame. A crossbeam is arranged between two symmetrically arranged crossbeam fixing seats. Lining plates are arranged on the upper surfaces of the profiling support frame and the profiling support blocks. Profiling holes are arranged on the upper surface of the lining plate, and detection pins are inserted into the profiling holes. A plurality of detection card plates are fixed on both surfaces of the crossbeam.

[0006] In one embodiment, the thickness of the lining plate is 5 millimeters. The crossbeam cooperates with the first vertical elbow clamp presser. Guide holes are arranged at both ends of the crossbeam, and corresponding guide holes are arranged on the upper surface of the crossbeam fixing seat. Guide posts are inserted into the guide holes.

[0007] In one embodiment, two positioning posts are arranged and are respectively inserted at both ends of the profiling support frame. One of the positioning posts is a diamond pin, and a bushing for fastening the positioning post on the profiling support frame is arranged between the positioning post and the profiling support frame.

[0008] In one embodiment, handles are provided on both sides of the upper surface of the cross beam.
