The front bumper is plugged and matched with the plug hole of the radiator grille body 13 through the plug on the front bumper body 12 (i.e., position A). Therefore, on the inspection fixture, the positioning of the matching position of the two parts needs to be made according to the product data. When designing, a disassembly positioning block is made, and a mark is engraved on the positioning block. When inspecting different single parts (i.e., the front bumper or the radiator grille), different disassembly positioning blocks are installed to ensure the measurement of the two single parts; when the front bumper or the radiator grille needs to be measured at the same time , remove all disassembled positioning blocks.

The profiling radiator grille positioning block can be plugged together with the inserts through the profiling grille insert holes 20, so as to connect the profiling radiator grille positioning block and the front bumper together; the profiling radiator grille positioning block is also provided with a pin guide hole 18 and a second locking pin 19, which are respectively used to lock and position the profiling radiator grille positioning block; specifically, refer to Figure 3As shown, the front bumper includes a front bumper body 12 and a front bumper frame 14. The front bumper is plugged and matched with the plug hole of the radiator grille body 13 through the plug on the front bumper body 12 (i.e., position A). Therefore, on the inspection fixture, the positioning of the matching position of the two parts needs to be made according to the product data. During the design, a disassembly positioning block is made, and a mark is engraved on the positioning block. When inspecting different single parts (i.e., the front bumper or the radiator grille), different disassembly positioning blocks are installed to ensure the measurement of the two single parts; when the front bumper or the radiator grille needs to be measured at the same time, all the disassembly positioning blocks are removed. If they are not removed, the assembly state of the front bumper or the radiator grille cannot be installed, and the product and the disassembly block interfere with each other and cannot be used. After the disassembly is completed, the assembly measurement can be realized; the inspection fixture can directly match the two parts, the two parts can be actually matched, and the gap between the two parts is directly measured, and then the assembly state is installed on the inspection fixture to measure the size. It is not necessary to rely on the measurement data of a single part to analyze the actual matching state of the two parts, which greatly reduces.

[0043] The utility model provides a check fixture for automobile front bumper and radiator grille. The check fixture positioning is made by imitating the installation points on the front bumper / grille real car. The check fixture is used to fix the product to be tested (i.e., the front bumper or radiator grille) on the check fixture. When the detection block is closed, the product is in a state to be detected. The surface difference gap of the product can be detected by using a dial indicator / surface difference gauge / pointed feeler gauge. Specifically, when detecting the radiator grille, the product is first installed, and then the imitation front bumper positioning block is inserted into the installation position (the lower part of the radiator grille is positioned on the front bumper), and the locking pin is tightened to reach the detection state. When detecting the front bumper, the imitation grille positioning block is first installed into the installation position (the upper part of the front bumper is positioned on the radiator grille), and the locking pin is tightened, and then the product is loaded, and the locking pin on the positioning block is tightened to reach the state to be detected.

[0044] The inspection fixture for the automobile front bumper and radiator grille provided by the utility model adopts a three-in-one matching assembly inspection fixture design, which can save the development of two sets of inspection fixtures and reduce the development cost of the inspection fixture; it can simultaneously perform separate or combined inspections on the front bumper and radiator grille, simulate the actual vehicle installation state, reduce the matching time of the front bumper assembly, and has strong practicality.
