When in use, the corresponding first rear floor profile detection block and the first rear floor screw hole detection block are installed on the corresponding position of the crossbeam according to the design standard, and then the crossbeam is fixed above the rear floor of the vehicle to be inspected through the front stand and the rear stand. By comparing the matching degree of the first rear floor profile detection block and the first rear floor screw hole detection block with the rear floor of the vehicle to be inspected, it is determined whether the rear floor of the vehicle to be inspected is qualified.

[0005] Furthermore, a plurality of second inspection components are installed on the workbench, each of the second inspection components comprises a base and a rocker arm, the base is installed on the workbench, one end of the rocker arm is hingedly installed on the base, and the other end of the rocker arm is installed with a second rear floor profile detection block or a second rear floor screw hole detection block, the second rear floor profile detection block is provided with a second detection portion that matches the surface contour of a standard automobile rear floor, and the second rear floor screw hole detection block is provided with a second bolt detection pin. By arranging rocker arm-type detection components in different places, it is convenient to detect detection points that cannot be detected by the first inspection component.

[0006] Furthermore, two handles are installed on the upper end surface of the beam to facilitate holding and testing.

[0007] Furthermore, the cross-sections of the first trough body and the second trough body are in an inverted "T" shape, which is convenient for installation.

[0008] Furthermore, the crossbeam is made of aluminum alloy profiles, which is light and easy to produce.

[0009] Furthermore, a plurality of go / no-go gauges are installed on the workbench to facilitate checking the size of the rear floor of the car.

[0010] Furthermore, a wire measuring instrument is installed on the workbench. Since the detection point on the bottom surface of the rear floor of the car is generally too far from the edge of the workbench and cannot be reached by human hands, the detection can be achieved using the wire measuring instrument.

[0011] The beneficial effect of the utility model is that the inspection tool adopts the crossbeam as the carrier of the inspection component, which is convenient for inspecting various elements in the central area of ​​large-sized parts. BRIEF DESCRIPTION OF THE DRAWINGS
