The method for inspecting a digitally printed vehicle head and bottom plate according to claim 1, characterized in that: The following steps are involved: S1: The user pushes the connecting rod (41) with a glove, the connecting rod (41) drives the pulling plate (42) to move to the left, the pulling plate (42) drives the clamping plate (43) to move to the left, and at the same time compresses the spring (44), the clamping plate (43) moves to the left and separates from the guardrail (107), and then the bottom plate base (101) is removed, and then S2 is executed; S2: The user pushes the hand push plate (5), the hand push plate (5) drives the push rod (32) to move toward a side away from the positioning block (31), the push rod (32) drives the movable plate (33) to move toward a side away from the positioning block (31), the movable plate (33) drives the clamping rod (34) to move toward a side away from the positioning block (31), so that the clamping rod (34) is separated from the positioning block (31), and the positioning block (31) is pulled out through the bottom plate (106) and the bottom plate connecting shell (105), and then S3 is executed: S3: The bottom plate (106) and the bottom plate base (101) are placed on a three-coordinate detection device respectively. The three-coordinate detection device extracts the processed bottom plates (106) and bottom plate bases (101) at a ratio of 2%-3% and sends them out for dimension measurement and accuracy verification using a three-coordinate device. Then, a machine test is performed. The user directly installs the bottom plate (106) and the bottom plate base (101) on the test device, performs a production test according to the production acceptance standard, and verifies the actual accuracy.
